Description

UNITED STATES PATENT OFFICE.
R.l A. WILDER, OF SGHUYLKILL HAVEN, PENNSYLVANIA.
FEED-WATER APPARATUS FOR LOCOIVIOTIVE-ENGINES.
Specification of Letters Patent No. 27,662, dated March 27, 1860.
To all whom it may concern:
Be it known that I, R. A. 1WILDnn, of Schuylkill Haven, in the county of Schuylkill and State of Pennsylvania, have invented a newand useful Improvement in the Method of Supplying Feed-Tater to the Boilers of Locomotive-Engines, of which the following is a full and exact description, reference vbeing had to the accompanying drawing, of which- A represents the apparatus in place on the side of the boiler, just beneath the check valve, and Figures l, 2, and 3, represent the apparatus in separate parts.
My invention consists in the arrangement of a two way valve, in'connection with the pump, the overflow pipe and the feed pipe by which the supply of feed water may be so regulated that any desired quantity may be conveyed to the boiler and a surplus if any be conveyed through an overflow pipe back to the tank. By this arrangement the pump may be kept in constant use thereby lessening the chances of its getting out of order and preventing it from freezing up in cold weather.
The dra-wings clearly illustrate and eX- plain the construction and use of my improvement.
a is the rod by which the engineer moves the arm.
o is an arm which attached to the valve regulates the direction of the flow of water.
c is a pipe connecting the pump with the valve chamber.
d is a pipe conveying the overflow of water back to the tank.
e is a hose connecting the overflow pipe with the tank.
f is a hose to convey the feed water from the tank to the direct feed pipe.
F ig. l represent-s the valve arrangement separated from the engine boiler. Fig. 2 is the valve and packing box. Fig. 3 is the arm or the lever by which the valve is moved.
YVhen it is not necessary to feed the boiler the valve is set so as to bring the opening in it in line with the pipes c and d, the pressure of the steam in the boiler keeps the check valve from lifting and the water passes from the pump through the pipe back to the tank. When the valve is moved so as to close the overflow pipe d all the water is forced into the boiler and hence it will be readily seen that by placing the valve at any point between the two positions described a portion of the water will be forced into the boiler' and a part flow back to the tank. By my improvement the supply of water to the boiler may be constant and adapted to the quantity evaporated under all circumstances.
Claim- The arrangement substantially as herein shown and described, in connection with the feed and overflow pipes and pump, of a tw o way cock, so that while a constant circulation of water is maintainedin said pipes, only such portion thereof as may be desired shall enter the boiler, all as set forth.
In witness whereof I have hereunto subscribed my name the 27th day of March, eighteen hundred and fifty seven.
R. A. VVILDER.
In presence of- IV. E. VVILsoN, W. S. COULTER.
