STAN D-PIPE FOR LOCOMOTIVES.

SPECIFICATION formingpart of Letters Patent No. 534,988, dated March 5, 1895.

Application filed May 10, 1893.

To all whom, it mayconcern:

Be it known that I, OTTO H. ARNER, a citizen of the United .States, residing at the city of Three Rivers, in the county of St. Joseph and State of Michigan, have invented certain new and useful Improvements in Stand-Pipes for Locomotives, of which the following is a specification.

Myinvention relates to stand-pipes for supplying water to locomotives.

The objects of my invention are, first, to provide a stand-pipe that is easily operated and held to place; second, to provide a valve that shall be operated principally by the water pressure in the Water-main third, to provide a means for preventing injury to the main water pipe from a sudden closing of the valve; fourth, to provide an easy way of starting the action of the valve; fifth, to provide a valve that is operated by the water pressure in the main pipe that does not require an elbow in the main pipe, and sixth, to simplify the construction of this kind of appliances, generally. I accomplish these objects by the mechanism shown in the accompanying drawings, in which- Figure 1. is a side view of my invention. Fig. 2 is a view partly in section on line 2--2 looking down. Fig. 3 is a sectional view on line 3-3 of Fig. 2 looking in the direction of the arrows. Fig. 4 is a sectional view on line 4=4 of Fig. 2 looking in the direction of the arrows, the pipe J not being shown. Fig. 5 is a sectional view on line 5-5 of Fig. 1 looking in the direction of the arrows. Fig. 6 is a sectional view on line 66 of Fig. 2. Fig. 7 is a sectional view on line 7-7 of Fig. 5. Fig. 8 is a sectional view on line 8-8 of Fig 5.

Similar letters of reference refer to similar parts throughout the several views.

B. is the main water pipe leading to the valve mechanism of my invention.

0 is the delivery pipe made in the usual form.

The end of the water pipe B is enlarged to unite with a valve chamber S for the main valve N. The delivery pipe 0 opens from the valve chamber S. A water cylinder A extends beyond the valve chamber S in line with the same. Fitted to this cylinder is a piston head M which is connected by piston Serial No. 473,636. (N0 model.)-

rod 1') to the valve N. The diameter of the piston head M is greater than that of valve N. Connected to the water cylinder A, at the cylinder head, by pipe R, is the auxiliary valve D. A small pipe J connects the valve chamber of this valve D to the end of the main water pipe B. The valve stem f of this auxiliary valve is a hollow tube, the opening of which extends around through the valve slide g and is adapted to be opened and closed by moving the slide g, the opening being adapted to the part of pipe R. The lever H is fixed by a set-screw to the valve stem f and is adapted to operate the slide 9 by tipping up and down, which rotates the hollow stem and so moves the slide 9.

The lever H is forked at the end, an arm passing each side of the upright portion of the delivery pipe 0, and into annular grooves in the collar G, which surrounds the pipe 0 and is adapted to rotate and reciprocate up and down on the pipe 0. The ends of the arms of the lever H are adapted to slide in the annular groove of this collar G. To the opposite sides of this collar are attached connecting rods I that passup each side of pipe 0 and connect with the double arms of the bell crank K. A connecting rod connects this bellcrank K to the operating lever L. It will thus be clear that the auxiliary valve D is operated by lever L and itsconnection to the valve stem f. By examining valve D (Figs. 5 and 7) it will be seen that when the slide is moved to one side of the port to pipe R, water will pass from the main pipe B through pipe J to valve D, through pipe E into the water cylinderA. The area of the piston head M being greater than that of valveN and the Water being under the same pressure in the cylinder as in the main pipe 13, the valve will be opened and so let the water pass into the valve chamber up through the delivery pipe C. It is thus clear that to open this main valve N, all that is necessary is to operate the auxiliary valve D, and the water pressure will open the main valve N.

To stop the flow of water, the slide 9 is moved over the port to pipe R and the water in the cylinder A will be forced out through the hollow valve stem f and by the pressure of the water in the main pipe on valve N as sisted at the start by water in the vertical ICO part of the delivery pipe O, water from pipe J will press the valve g firmly against its seat 9'.

The delivery pipe of the stand -pipe is adapted to turn so that the horizontal portion can be brought over the tender of a locomotive on a rail-way track. Pivoted to lugs on each side of valve chamber S are two levers F, the lower ends of which are held apart by coil spring P which passes through a tubular opening in the base on which my device rests, thus forcing the upper ends of the levers toward each other. On the upper end of each lever are transverse horizontal bars F bent at an obtuse angle where they join the lever, the ends of the bars being bent toward the pipe 0. On the bottom part of a movable portion of the delivery pipe 0, are two rollers 00 mounted on opposite sides. The rollers a are adapted to roll on the arms F. When the pipe is in position shown in Fig. 2, the rollers a rest in the angles of the bars F and the pipe is held in that position with force sufiicient to prevent the wind blowing the horizontal portion of the pipe from its position. When the pipe is turned one quarter around the rollers n are held by the ends of the arms F and the pipe is secured similarly in that position.

The valve E is to relieve the main pipe B from the strains due to suddenly closing the valve N, or from other causes.

The valve chamberE, is cylindrical in form. In the cylinder is a loose fitting piston head 1 connected by a piston rodt to a tight fitting cylinder head 8 at the opposite end. On the outside of the tight fitting head is a valve 8' held to place by a coiled spring 07. suitably confined. On a sudden increase of pressure, the valve 3' will compress the spring 17. and open, allowing water to escape. The water will then soon leak by the piston head 0" and press the valve seat against the valve. When the pressure subsides, the spring crowds all back tb the original place. A gradual change will only compress the spring without opening the valve. It is the sudden change in pressure that causes the damage.

My invention is capable of many variations in its details. It is immaterial how the valve D is operated or where it is located, so long as it connects, in the manner specified with the main water'pipe, and water cylinder. The form of the valve can be varied so long as it accomplishes the result; and it is clear that many variations of connecting a piston of larger areathan the main valve to the valve so that the water pressure in the main can be utilized to open the valve, and the pressure then shut off so that the direct pressure will close the valve, will readily occur to a skilled mechanic on examining my invention. There are'other relief valves that could be used in this combination than valve E. I have shown myinvention carried out in the most approved form.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination in a stand-pipe for supplying water to locomotives, with a quick closing valve of areliet' valve composed of cylinder E and ot' pistons r and 5 connected by rod t and the valve 3 adapted to compress a spring u and the spring 'Lt, substantially as described.

2. In a stand pipe for locomotives, the combination of the main water pipe, B; the water cylinder, A, at the end thereof having the same general direction; a piston, M, inside of the water cylinder; a valve, N, of lesser area than the piston, M, to close the opening at the end of said water main, the piston rod, B, connecting said valve, N, and said piston,M; the delivery pipe, 0, leading up from said water cylinder between the piston head, M, and the valve, N; a pipe, J, leading from said water main, B, through to the head of said cylinder, A; a valve case, D, in said pipe, J; a valve, g, in said valve case adapted to swing on the plate bushing, g; a passage through said valve, g, to the exterior adapted to swing o ver the port to the portion of the pipe leading to the head of said cylinder; a lever, H, connected to said valve, g, to swing the same; and suitable connections to said lever H, so that the valve can be operated to admit water to the head of the cylinder to operate the valve, and when the water valve is swung into place, allow the water to escape from said water cylinder to permit the direct pressure in the pipe to close the same, all substantially as described for the purpose specified.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
