The Jewell Pure Water Company was incorporated in Illinois on January 25, 1888 with a capital stock $500,000, for the manufacture of water filters, etc.; incorporators, Frank F. Fisher, James McLean, and William Devine. The new company was sued by the Hyatt Pure Water Company in August to restrain use of the phrases "Jewell Pure Water Company" and "Jewell Pure Water System." The case was settled and dismissed the following February, at which point the company appears to have changed its name (or was reincorporated) as the O.H. Jewell Filter Company.
The Morison-Jewell Filtration Co. incorporated April 14, 1893 in Camden, New Jersey to Manufacture Filters, capital stock $100,000.
The company fought several patent infringement battles with the owners of the Hyatt filtering patents, and in March, 1898 agreed to license the Hyatt patents. In 1900 the O. H. Jewell Filler Co. and the Continental Filter Co. consolidated with the New York Filter Manufacturing Company to form New York Continental Jewell Filtration Co.

1891 "The Jewell Gravity
Filter," Fire and Water 22(1) (November 28, 1891)
Among the several systems in use for the mechanical filtration of water is
that known as the Jewell Gravity Filter, illustrated herewith, which,
while it has been before the public for comparatively few years, has been
quite extensively adopted, especially where large quantities of water were
to be treated, as in public water-works systems, paper mills, and other
large manufacturing establishments. The tanks of these filters are
made of cypress wood, for which material the advantages are claimed that
it is practically indestructible in water, is less expensive than steel,
and, as the tank can be shipped to its destination "knocked down," will
facilitate the erection of the latter in places where it would be a
difficult task to put up one of metal.
Among the claims in favor of the general character and operation of the
device are that most of the impurities are restrained near the surface of
the filtering medium, and that, consequently, the quantity of water needed
to wash the filter is reduced to a minimum ; also economy, in that the
filtering medium does not require to be replenished, the impurities being
washed away at regular intervals of time by simply reversing the flow of
water.
There are now in operation Jewell filters of an aggregate capacity of
upwards of 25,000,000 gallons daily capacity, serving not only to clarify
muddy water and remove suspended impurities, but also to eliminate
bacteria or other micro-organisms, and to free water for boiler use from
lime and magnesia. It is claimed that this filter will develop results
identical with those obtained in the laboratory, freeing water from
organic impurities, objectionable gases and minerals held in solution, if
in conjunction with the filter proper, there is used a re-agent suited to
the specific work to be performed.
The sizes in which the filters are made vary from 6 to 12 feet diameter by
14 feet height, with capacities ranging from 125,000 to 500,000 gallons
daily. A 2,000,000 gallon battery is now being erected for the American
Wood Paper Co., divided between its mills at Spring City and Manayunk, Pa.
This company has already had the system in use nearly two years. A battery
of gravity filters of 1,000,000 gallons capacity was also recently put in
at the works of the Kalamazoo Paper Co., Kalamazoo, Mich., and one of like
capacity is now in course of construction for the Bardee Paper Co.,
Otsego, Mich.
These filters are manufactured by the 0. H. Jewell Filter Co., No. 73 to
75 West Jackson street. Chicago, and the Morison-Allen Co., No. 145
Broadway, New York. A system of pressure filtration is also controlled by
the same manufacturers.

Final Decision on a Mechanical Filtration Patent," Engineering
News 33:44-45 (January 17, 1895)
After seven years of litigation the legal status of patents covering the
use of alum or similar coagulants in the fiItration of water has been
determined beyond appeal. It is now settled that the application of such
coagulants to water, which after such treatment is passed immediately to
and through a filter bed (in other words, without intermediate settling
basins), is an infringement upon patent No. 293,740, granted Feb. 19,
1884, to Isaiah Smith Hyatt. This patent was entitled, “A Method of
Purifying Water,” and is now owned by the New York Filter Co. The history
of the case is as follows:
In April. 1887, the Newark Filter Co., which then controlled the above
patent, filed a bill of complaint in the U. S. Circuit Court, District of
New Jersey,. against the National Water Purification Co., alleging
infringement of the patent. asking for a perpetual injunction and for
$50,000 damages. Shortly afterwards the Newark Filter Co. became the Hyatt
Pure Water Co., and in June. 1888, it began suit in the U. S. Circuit
Court for the Northern District of Illinois against another alleged
infringer of the same patent, the Jewell Pure Water Co.
The second suit was dismissed at the complainant's cost, on Feb. 13,
1889. Moreover, on July 27, following, a disclaimer to the original
Hyatt patent, mentioned above, was filed, striking out a part of the
specifications, in which certain broad claims were made. This disclaimer
is cited below. The original suit between the Hyatt and National Cos. was
continued, if we are correctly informed, until their consolidation, early
in 1892, as the New York Filter Co. as noted in our issue of Feb. 20,
1892. The American Filter Co., of Chicago, was also included in this
consolidation, and in addition the new company now holds the patents on
the filter known as the Blessing, and certain patents on the aeration of
water, formerly controlled by the U. S. Pure Water Co.
On May 1, 1893, the New York Filter Co. again took up the suit on the
Hyatt patent, alleging infringement in the case of a Jewell filter, in use
at the Murray Hill Turkish Baths, New York city. Meanwhile, the Jewell
Pure Water Co. had become the O. H. Jewell Filter Co. On June 9, 1894,
Judge Shipman, of the U. S. Circuit Court, for the Southern District of
New York, rendered a decision in favor of the New York Filter Co.. as
stated in our issue of June 28, 1894. The case was carried to the United
States Circuit Court of Appeals, a stay of injunction being granted,
meanwhile, by Judge Shipman. On Nov. 1 and 2 an argument on the appeal was
made before Judges Wallace, Lacombe and Coxe, and on Jan. 9, 1895, an
opinion was filed by Judge C. J. Wallace affirming the decree of the
Circuit Court.
Judge Wallace's opinion seems much clearer than that of the lower court.
He states very plainly that, in using alum in filers without the
intervention of settling basins, there is an infringement; but that with
such basins there is not.
Having given the history of the case, some reference may be made to the
claims of the original Hyatt patent, upon which so much litigation has
been based. The claim allowed in this patent was as follows:
The method hereinbefore described of
arresting and removing the impurities from water during an uninterrupted
passage of same from a supply-pipe into a filtering apparatus, thence
through a filter-bed contained therein, and out through a delivery-pipe
leading therefrom, which method consists in introducing into the water
simultaneously with its passage to or into the filter a substance which
will sufficiently coagulate or separate the impurities to facilitate
their arrest and removal by the filter-bed, thus obviating the necessity
of employing settling basins.
As will be seen, the above claim specifies no chemical to be used as a
coagulant. The specifications, however, refer several times to persulphate
or perchloride of iron, or “other coagulating agent." or words similar to
the three quoted, and in a paragraph stricken out in a subsequent
disclaimer. already mentioned, permanganate of potassa, was named. This
disclaimer was as follow::
I do not confine myself to the
employment of persulphate or perchloride of iron or permanganate of
potassa, but make use of any other suitable agent which is capable of
coagulating the impurities of the liquid, and preventing their passage
through the filter-bed. Neither do I limit myself to any particular
proportions or quantities of the coagulating agent, as they may be
varied according to circumstances and the character of the liquid to be
treated. Nor do I confine myself to any particular liquids. although I
contemplate chiefly the purification of water in large quantities.
In this suit the defendants had urged that the Hyatt patent was null
through lack of originality and that, whether null or not, the disclaimer
limited the patent to the two salts of iron named. After reviewing the
case and referring to some references to earlier patents, Judge Wallace
says, in answer to the first point:
The patent in suit describes a
departure from anything which appears to have been done or known in the
prior art, so far as appears by the record.
The departure consists in the discovery, in the language of the Judge.
“that the agglomerating action of the coagulants could be obtained without
waiting a considerable time for precipitation. or during the passage of
the water through the filtering-bed."
Judge Wallace's conclusions, tn regard to the disclaimer and his summary
of the case, are as follows:
The patent after the disclaimer is
to be read exactly as though the recital had never been inserted. Thus
read. it is clear that the claim covers the use of any coagulant having
similar properties to the salts of iron. which was a recognized
equivalent.
As thus construed, the infringement
of the claim by the defendants is established, although they use alum as
the coagulant instead of the salts of iron. In some of the plants of the
corporation defendant settling tanks are used between the introduction
of the coagulant and the filter-bed. In these plants the method of the
patent is not appropriated, and there is no infringement.
The decree of the Circuit Court is affirmed with costs.
Of course, the decision applies to all companies or persons making or
using mechanical filters in which alum or a similar coagulant is
used. Wherever the water receives the coagulant as it passes into
the filter, the Hyatt patent is infringed, but if settling tanks are
employed, in Judge Wallace's words, "there is no infringement."

The Consolidation of Two Mechanical Filter companies after several years
of bitter conflict, as noted from time to time in this journal, has been
effected as set forth in the following official statement:
Within the past few days, and as the result of the long and successful
litigation of the New York Filter Manufacturing Co. against the Jewell
filter, the O. H. Jewell Filter Co., of Chicago, Ill., has made settlement
for its past infringements and taken a license under the Hyatt patent, by
the terms of which it becomes the exclusive licensee under the Hyatt
patent for all territory west of Pennsylvania, north of the Ohio River and
west of the Mississippi River, including Tennessee and Kentucky. Hereafter
the New York Filter Manufacturing Co. will confine its business to the
eastern territory, and within that territory will supply the Jewell
filter. The Morison-Jewell Filtration Co., of New York and Philadelphia,
has likewise made a settlement, and is to retire from business. The New
York Filter Manufacturing Co. has elected as its President, Mr. W. G.
Warden, of Philadelphia, and as General Manager, Mr. Samuel L. Morison,
heretofore Vice-President and General Manager of the Morison-Jewell
Filtration Co. The emcee of the company will continue for the present to
be located at 120 Liberty St., New York city.
In the some connection it may be noted that the Loomis filter,
manufactured by the Loomis-Manning Filter Co., of Philadelphia, has been
declared to be an infringement on the Hyatt patent, in so far as the use
of alum is concerned. This declaration was made on Feb. 26, in connection
with a preliminary injunction granted by Judge Lacombe of the United
States Circuit Court for the Southern District of New York.

Gentlemen: We have repeatedly had called to our attention the fact that
Ira H. Jewell, of Chicago, Ill., represents himself as being identified
with the Jewell Filter, and also represents himself as being backed
financially by his father, O. H. Jewell, of the O. H. Jewell Filter
company, of Chicago. We called Mr. O. H. Jewell's attention to the
matter, and he makes the following statement, which we wish you would give
as prominent a place in your paper as you possibly can :
Chicago, Ill., February 20, 1901. To whom it may concern:
It having frequently come to my notice that Ira H. Jewell, my son, is
representing himself as identified with the “Jewell Filter,” manufactured
by the O. H. Jewell Filter company, and with myself as his financial
backer. I find it necessary to state publicly that the said Ira H. Jewell
has had no connection whatever with the O. H. Jewell Filter company since
selling his stock interest therein over one year ago, and never with its
successors in the filter business, the New York Continental Jewell
Filtration company, nor has he any business relations with me of any
description.
Any statements of his, or those of his representatives, that he is
authorized to do business of any sort for the O. H. Jewell Filter company,
or its successors, as above, are unqualifiedly false and without
foundation.
Respectfully yours, (signed) O. H. Jewell, Western General Manager, N. Y.
Continental Jewell Filter Co.
We would call attention to those interested to those interested in filters
to the name of Ira H. Jewell's company, the I. H. Jewell Filter company,
as it is so much like the O. H. Jewell Filter company as to be
misleading. The I. H. Jewell Filter company or the New York
Continental Jewell Filtration company, nor with the Standard Jewell
Filter, which we manufacture and well, and the patents of which we
control.
Yours very truly, N. Y. Continental Jewell Filtration Company, Geo. E.
Burroughs, Secretary.

1907 Engineering
News 57:582 (May 23, 1907)
Mr. Samuel L. Morison, President and General Manager of the Jewell Export
Filter Co., died in London on May 21. Mr. Morison was born in Baltimore,
Md., 56 years ago. He was a descendant of an old Maryland family. He
graduated from Harvard in the class of 1873, and became a member of the
firm of Gillies, Morison & Co., first representing the Philadelphia
house of Morris, Tasker & Co. in New England, and later carrying on an
independent business in the sale of water-works supplies. In 1879 Mr.
Morison's firm purchased the brass works of Hayden, Geer & Co., and
reorganized it as The Hayden Co. Other concerns were taken in, and the
United Brass Co. was later formed. After ten years of successful work in
the brass industry, Mr. Morison and his partner became interested in the
new business of mechanical filtration, taking up first the exploitation in
the East of the Jewell patents on mechanical filters. Mr. Morison soon
became a prominent factor in the development of the mechanical filter
business, and had an active part in several of the organizations which
finally were merged in the New York-Continental-Jewell Filtration Co.
After the business of mechanical filtration in the United States was
placed on a firm basis, Mr. Morison's energies were enlisted in the
development of the American mechanical filter for foreign countries. He
organized and became president of the Jewell Export Filter Co., and has
for several years been carrying on an extensive business in the
introduction of mechanical filters in Europe and Asia. Large filter plants
at Alexandria and Cairo, Egypt; Trieste, Austria; and in India, Russia,
England and France, were carried out under his direction. The most
important plant in the United States with whose construction Mr. Morison
was intimately connected with that of Little Falls, N.J., which still
remains the largest mechanical filger plant in the world. Some three
years ago Mr. Morison fell in an office building in New York and broke his
ankle. The fracture failed to heal property and has given constant
trouble ever since, although it has not prevented him from continuing in
active business. He sailed from New York on the "Baltic" on April
10, but the old sound, which had been growing worse of late, finally
caused blood poisoning, which resulted in his death. Mr. Morison was
a member of the Society of the Cincinnati, and of the University and
Manhattan Clubs in New York City.
1907 "Death
of Samuel L. Morison," Fire and Water Engineering 41(22):293
(May 29, 1907)
On May 21 Samuel L. Morison, president and general manager of the Jewell
Export Filter company died in London, England, from blood-poisoning, the
result of a fractured ankle. He met with the accident three years ago,
when he fell in a New York office building. The healing process was never
completed, and Mr. Morison was constantly suffering from it. He left New
York on April 10, and in London the old wound grew worse till death
ensued. Mr. Morison was born in Baltimore fifty-six years ago and
graduated from Harvard University in 1873, after which he engaged in
business in Philadelphia as a member of the firm of Gillies, Morison &
Co., the sale of waterworks supplies chiefly engaging his attention. In
1879 he purchased and organised as the Hayden company, the brassworks of
Hayden, Geer & Co., forming, in course of time, by uniting with other
concerns, the United Brass company. After following that business for ten
years, he engaged in that of mechanical filtration—a new industry in those
days, and took up the Eastern rights of the Jewell patents on that type of
filtration work. He was prominently associated for many years with the New
York Continental Jewell Filtration company, after which he organised the
Jewell Export Filter company for the development abroad of the American
mechanical filtration system, which had by this time become firmly
established in the United States and Canada. He was instrumental in
building and installing mechanical filtration plants on a large scale at
Alexandria and Cairo, Egypt, Trieste, Austria, and in several cities in
England, Russia and India. On this side of the Atlantic he was identified
with the mechanical filtration plant at Little Falls, N. J., the largest
of its kind in the world. Mr. Morison was a great favorite among
waterworks men and was always a good friend to all with whom he was
connected in business or socially.

John F. Wixford, the city chemist generally credited with the formula that
made city water clear just before the World's Fair opened on April 30,
1904. The photo is from June 1927, shortly after Wixford returned to the
city staff after an absence of 21 years. Wixford graduated from Washington
University with a degree in engineering and first joined the city in 1903.
At the time, city water flowed from faucets and hydrants with a
distinctive brown hue. The reason was the muddy Mississippi River at Chain
of Rocks, where the city still has a water works. (The mud actually is
mainly from the Missouri River, which joins the Mississippi five miles
upstream from Chain of Rocks.) Wixford adjusted the treatment method used
in Quincy, Ill., by greatly increasing the amount of lime used to get
sediment to sink much more quickly to the bottom of settling tanks. When
the city began using Wixford's formula of lime and iron oxide, the water
ran clear, and did so only one month before the fair opened in Forest
Park. Wixford tried to patent the formula, but mayor Rolla Wells
complained publicly that many people were involved in the deal. Wixford
resigned in 1906 during the controversy, but later administrations praised
his work. He died in 1935 at age 74.
