Patrick Clark was born in Roscommon, Ireland on April 2, 1818. He and his family came to America in 1827 and settled in New Jersey. His father died soon thereafter, and his mother moved the family to New York City There Patrick's siblings and mothers all died, and he went back to the young community of Rahway. He found employment and became sole proprietor of the Rahway Manufacturing Company that manufactured his patented blowers. His inventive mind secured several patents, he he was involved with the local gas company before being hired as the engineer of the Rahway Water Board in 1878. He designed and built a mechanical filter that he let the Water Board use at no charge, and he later secured a patent for his design. In late 1880 he was one of the founders of the Newark Filtering Company, where he remained until his death.. .
Pillsbury died on March 5, 1887 in Rahway, New Jersey.

Incorporated by Joseph T. Crowell, Thomas H. Shafer, Joseph S. Smith, Patrick Clark, and Samuel Williams "to supply the city of Rahway with good and wholesome water, in quantities sufficient for all the purposes which may conduct to the safety of said city, and to the health and comfort of the citizens." This company did not build anything.

Our ingenious townsman, P. Clark, Esq., has constructed a water filter, one of which he has introduced into the City Water Works, which is a great improvement on any heretofore made. Most persons who have employed a filter for domestic use, have found its value lessened by the deposition of sedimentary matter on its inner surface. Unless frequently cleansed the filter becomes clogged or the silt, unable otherwise to escape, is forced through the filter, thus destroying the value of the appliance. For these reasons many persons have discontinued the use of such articles entirely, and prefer accepting the water in its natural state to the care and trouble of keeping a filter in good working order.
Tho improvements made by Mr. Clark obviate all the above-mentioned objections. His new filter clears itself of all impurities, as it separates them from the water. By an ingenious arrangement the silt and sediment which accumulate in ordinary filter», are carried away by a separate flow of water, and thus tho instrument never becomes foul and cannot become clogged. We believe Mr. Clark thinks of securing a patent for his filter, though he proposes to allow the city tho free use of its advantages, having, as we said, already introduced one into our Water Works, at which place he would be pleased to explain its workings to any one interested in such matters.

We are informed that a patent has been granted to our townsman, Patrick Clark, Esq., for an improvement in filters similar to the one built by him for our Water Works about sixteen months ago, and which during that time has furnished the city with unobjectionable water. The improvement being fundamental is considered valuable by by those who are competent judges. [Clark had filed an application for a patent on October 18, 1880, which was granted the following June.]

The writer took charge of the Rahway water-works on the first of June, 1879. The pumping station is on the north branch of the Rahway river, which furnishes a minimum supply of ten million gallons of water every twenty-four hours. The works have no reservoir or stand pipe, but pump directly against the mains. Two duplex compound engines are used alternately month about each engine being capable of pumping one and one-half millions every twenty-four hours. The daily consumption of the city is about five hundred thousand, but the amount for short periods occasionally runs up to on million gallons. The water remaining in the reserve pumps and mains always became grossly offensive at the end of three or four days after the stoppage of the pumps. In June, 1880, a sand filter was placed between the works and the river. The result was that the water remaining in the idle pumps and mains at the end of a month was sweet and palatable.

Page 580: Patrick Clark, Proprietor, Rahway Manufacturing Company, Manufacturers of Clark‘s Patent Single, Double and Quadruple Pressure Blowers and Exhausters.--The shops of the Rahway Manufacturing Company, of which Mr. Patrick Clark is the sole proprietor, were established by that gentleman in 1873 for the exclusive manufacture of his patent single, double and quadruple pressure blowers and exhausters. They are adapted to cupola furnaces. Smith’s forges and jeweler‘s fires, rolling-mills, steam boiler fires and for metalurgical purposes generally. Exhaust fans for removing dust from emery wheels, dry grind-stones and shavings from planing-machines, etc. Also, for ventilating buildings and mines, and for drying wool, cotton, paper, leather, oakum, glue. hair, fruit, and for all purposes where a current of air is required. Years of experience has enabled Mr. Clark to eliminate many defects of construction and design, and he now offers perfect blowers to the manufacturing community confident of their durability and efficiency, and they are guaranteed in every respect in accordance with representations. Fully two thousand of them are now in use throughout the United States. They are constructed of the best materials, the shafts being made of the best steel; the journals run in Babbitt metal, and are self-oiling, and the fans are too strong and light to be broken at the highest speeds. These blowers are noiseless and are universally commended by those who have them in use. Prices range from $20.00 to $700.00. The factory is 40x50 feet in size, built of brick, and is two stories in height. The most approved machinery is used in their manufacture and competent workmen are employed. A six-horse engine furnishes the motive power for the machinery. Mr. Clark, the patentee and manufacturer of Clark’s patent blowers and exhausters, is a native of Ireland, but came to this country in his boyhood.

In a crude way the water filter took form at Rahway under the hand of Patrick Clark.
Called on in March, 1876, to find a remedy for the "almost constant turbid condition" of the water supply of Rahway, Patrick Clark, the city engineer, reported that instead of furnishing "spring water" from an infiltration basin built in 1871, a large part of the supply was drawn from the North Branch of the Rahway River, made turbid by every rain. He advised the construction of "a large settling reserroir and filtering apparatus." The board engaged for this purpose George H. Bailey, who designed filter basins for Newark and Rahway. Almost immediately, the water board abandoned the project.
Clark became chief engineer of the Rahway Water Board on May 8, 1878. On October 21, 1880, he resigned his position and the board voted that the filter constructed by P. Clark at the works be allowed to remain there." When and under what conditions it was put in, its nature and how long it remained in service is unknown. In a special report of the Tenth Census of the United States, transmitted to the director on June 1, 1882, these words appear in a description of the Rahway waterworks: "Filtering Apparatus: Clark filter, 16 ft. sq.; 5and, 6 in. deep on fine wire cloth; cleaned once in 24 hours. Consumption, 0.5 mgd." This indicates a filtration rate of 85 mgd per acre.
Four days before his resignation, Clark applied for a patent on his filter.

Page 183: Clark's contribution to the art of mechanical filtration was the application of vertical jets of water to aid in cleaning filter media supported on a false bottom. He built a filter at Rahway, N.J., in or just before 1880. In October 1880, he applied for a paLent. In December, he, John W. Hyatt and Albert C. Westervelt incorporated the Newark Filtering Co.
