AIR-BRAKE PUMP FOR LOCOMOTIVES.
SPECIFICATION-fo1-ming part of Letters Patent No. 268,631, dated December 5, 1882,
I Application filed February i3, 1882. (No model.) y
To all whom it may concern:
' Beit known that I, DAVID J. DAMPMAN, a citizen of the United States, residing in Philadelphia, Pennsylvania, `have invented certain Improvements in Air-Brake Pumps of Locomotives, of which the following is a specification. The object of my invention is to provide means whereby the air-brake pump of a locomotive may when occasion requires be readily adapted for lifting and forcing water. This object I attain in the manner which I will now proceed to describe, reference being had to the accompanyingdrawin gs, in Which- Figure l, Sheet 1, is a side view of a locomotive, illustrating my invention, those parts to which the invention particularly relates being shown in full lines and the remainder in dotted lines; and Fig. 2, Sheet 2, is a side view, partly in section, ot' the pump and connections constructed in accordance with my invention.`
A is the steam-cylinder, and B the air-pumpin gcylinder, usually employed on a locomotive, in connection with the system of air-brakes Inovv generally used on railroad-trains.
D is the inlet-pipe of the pump, which communicates with both ends ot' the cylinder B` through branches having check-valves a; and E is the discharge-pipe, which likewise communicates with both ends of the cylinder B through branches having check-valves b. The inlet-pipe D has two branches, F and Gr, each furnished with a stop-valve, d, the branch F terminating in a rose or strainer, e, and the branch G being adapted at the end for coupling to a length of hose. The discharge-pipe E also has two branches, F and Gr', with stopvalves d', the branch F communicating with the usual air-reservoir on the locomotive, and the branch G being adapted for the reception of hose in the same manner as the inlet-branch G, above referred to. 'Under ordinary circumstances the stop-valves d d' in the lbranches Gr G are closed and those in the branches F FI opened, the pump in this case performing its y lbearings on the frame.
reaches a water-tank it becomes necessary to replenish the supply of water in the tender, the valvesin the branches F and F are closed, these in the branches GG are opened, a length of suction-hose is attached to the branch G, and a length ot' forcing-hose is attached to the branch G', the latter being preferably furnished with the usual air-chamber in order to insure a uniform discharge, the supply of water being obtained from any adjacent pond or stream. i
In order that the pump may work effectively in pumping Water, however, it is advisable to permit a greater lift of the valves c b than when pumping air, so that the entrance of water into and its discharge from the cylinder B` shall not lbe obstructed. For this reason I `provide the casing of each of the valves a b with an adjustable stem, m, which passes through a stuffing-box in the casin g and serves as a stop to limit the lii't of the valve. These stems m may he adjusted independently of each other 5 but I prefer to use the means shown inthe drawings, whereby the stems of both ot' the inlet-valves or of both of the dischargevalves can be operated simultaneously. The means shown comprise two rods, g, one con nected to the stems m of the valves a and the other to the stems of the valves b, each rod being threaded at the upper end for adaptation to the threaded hub of a wheel, n, which is confined vertically to but can turn freelyin By turning these wheels in one direction or the other the rods g can be raised or lowered and the lift of the valves (t or governed as desired, a suitable scale and pointer serving to indicate at a glance the extent of lift ofthe valves which is permitted.
In carrying out my invention the branch G of the inlet-pipe D may in some cases be dispensed with, provision being made for attaching the suction-hose to. the branch F after removing the rose or strainer therefrom; or, it' desired, the water supply and discharge pipes maybe independent of the air-pipes, and may have an independent set of check-valves. The arrangement shown in the drawings is, however, preferred on the score of economy and convenience.
IOO
I claim as my in venticuc.
l. The combination of the pump-cylinder B, its inlet pipe and valves, with two valved discharge pipes or branches, Fand G', one conn- 5 mnnicatin g With the air-reservoir and the other adapted for receiving hose, as set forth.
2. The combination of the pnmp-cyiinderB and its valves with inlet and discharge pipes D and E, each having two valved branches, as
1o specified.
3. The combination of the pump-cylinder B and its supply and discharge pipes, the valves a, and b, with stems m, the threaded rods g, and the wheels n, confined vertically and adapted to the threaded portions of the rods g, as set I5 forth. v
1n testimony WhereoiI have signed my name to this specification in the presence of two subscribing Witnesses.
