LOCOMOTIVE STAND-PIPE.

SPECIFICATION forming part of Letters Patent No. 489,245, dated January 8, 1893.

`Application led May 20,1892. Serial No. 433.725. (No model.)

T0 all whom it may concern:

Be it known that I, ROBERT HENRY WHITE, a citizen of the United States, residing at Kin gs ton, in the county of Ulster and State of New York, have invented a new and useful Locomotive Stand-Pipe, of which the following is a specification.

This invention relates to stand pipes; and it has for its object to provide an improved, automatically controlled, stand pipe adapted for use in feeding locomotive tenders.

To this end it is the main and primary object of the invention to provide an improved stand pipe having means whereby the same can be easily and readily controlled by the operator, and one which is easily repaired and by means of which the iiow of water can be accurately regulated and controlled so as to prevent overiiow of the tank or tender being fed.

With. these and many other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction combina` tion and arrangement of parts hereinafter more fullydescribed,illustrated and claimed.

In the accompanying drawings;-Figurel is a vertical sectional View of a stand pipe constructed in accordance with my invention. Fig. 2 is an enlarged vertical sectional view of the main valve casing. Fig. 3 is a detail .sectional view of one of the main upright pipe supporting rollers. Fig. et is a detail sectional view of the swiveled coupling.

Referring to the accompanying drawings A represents the ordinary platform upon which ordinary tank feeders are mounted, and below the sameis located the main valve casin g B of my improved stand pipe. The said valve casing B, is provided with an upwardly extending iianged neck h at one side, and a receiving inlet h at the other side, which inlet is coupled to the main water supply pipe b2, through which the water is led to the valve casing, and intermediate of the discharge neck b, and inlet b', is located the main valve seat ha, over which are designed to work the valves forming a duplex valve for controlling and regulating the inlet of water to the valve 5o casing.

'Working directly over the valve seat b3 is the main valve O. The said valve C is provided with the depending guide flanges or plates c, working through the main valve opening and guiding the valve in its up and down movement, and between said guide plates or iianges and the top of the valve is clamped the rubber valve cushion c', having a continuous rounded bearing tace c2 adapted to fit snugly upon the top of the valve' seat and provide a tight joint. The said valve O is further provided with the central inlet opening c3, surrounding which is the raised valve seat c4, and across which extends the valve guide c5.

Secured to the upper end of the valve stem D working through the valve guide c5, is the auxiliary valve d, provided with a cushion disk d', having an annular rounded bearing face cl2 adapted to rest upon the raised valve seat surrounding the opening through the main valve O. The said valve stem D is provided at a point below the main valve C, with the lifting shoulder d3, which, when the auxiliary valve d uncovers the opening through the main valve C, is designed to engage under the main valve and lift the same from its seat thus providing means for iirst relieving the entire pressure from the main valve before raising the same, and by irst closing the main valve C, reducing the column of water, before closing the auxiliary valve. The said valve stem D works through the top of the main closed water cushion chamber E located directly below the main valve seat in the bottom ot the main casing, and provided with the top and bottom inlet and discharge open-ings e, which provides means for allowing the water to iiow to and from the chamber-above and below the cushion piston e. The said cushion piston e is carried upon the lower end of the valve stem D within said chamber, and is provided with the cup packing e2 working against the sides of said chamber, said water chamber and the piston working therein providing means for the easy seating of the duplex valve without unnecessary jar or concussion.

Secured at the center of valve stem D above the top of the Water chamber is the valve operatin g lever F. The said lever Fis fulcru med in the ott-standing bracket f, secured to the top of said water chamber and is pivotally connected at its other end in the lower end of the swivel head G. The said swivel head G is provided with lower bifurcated end g receiving one end of said lever and with the flanged sleeve g', swiveling the threaded swivel block g2 to the body of said head. The said swivel block g2 receives the lower threaded end of the operating rod H working in the main upright discharge pipe l. The said discharge pipe I works through the base guide c supported above the platform A and is provided at its lower end with a closed base 1l', which projects into the discharge neck b of the main casing B. Thebottom of the base 'i' is provided with a central raised portion t2, while surrounding thelower edge of said base is the beveled face or track 3 resting directly upon the bevel supporting rollers J. The said bevel supporting rollers J are mounted upon the spindle bolts j, passing through opposite sides of the valve casing,and supportinglugs j', secured to opposite inner sides of said casing, so as to allow the main upright discharge pipe -to be freely oscillated,wl1ile at the same time when the pipe is out of use, the same is held fixedly in position .by said support-ing rollers being at the apex of the central depressed portion of the base, which also allows the upright discharge pipe to raise as the same is turned into position for use and throws the Water openings therein above and out of alignment with the drain valve to be described.

Olamped to the upper flanged end of the discharge neck Z) and tightly surrounding the base of the discharge pipe are the packing rings K, holding in place molded leather packing rings K which provide a water tight joint While at the same time allowing the main pipe to be rotated in the valve casing.

The base of the discharge pipe is provided above the lower end of the same with the Wa ter openings L, which are designed to allow the water to flow into the discharge pipe when the same is turned in a position for use with the rollers out of the raised portion of the bottom, while at the same time allowing the same to drain when turned back out of use. When the discharge pipe is turned in position out of use a hollow drain valveZnormally registers or aligns With one of said openings L, so as to allow the water remaining in the discharge pipe to pass out of the same through said valve. The said valve is provided with an extended discharge neck Z', working through the box Z2, secured to one side of the valve casing B, and said valve is held normally against the rotating base c" by means of the spring Z3, surrounding the same and forcing the head of the valve against said base, so that when the base is returned to its normal position, one of said openings, according to the direction in which the disj charge pipe is turned, aligns with said drain guide h secured within the discharge pipe I near the lower end of the same and which is provided with a drain passage 71X in the top thereof, which communicates with the auxiliary drain opening h2, in one side of the discharge pipe and also provide means for draining said pipe. Secured at its lower end in said guide h is the main guide tube M,Which incloses the greater portion of said rod extending` up through said discharge pipe, and which is connected at its upper end to the valve operating lever N, working through the crown of the discharge pipe and pivotally connected at one end to the bracket n.

Directly under the crown of the discharge pipe is located theair chamber O, within which travels the air cushion piston P, secured to the operating rod H, and acting in an auxiliar'y capacity to aid the water cushion, in easily seating the main and duplex valves and directly below said air cushion or chamber the main discharge spout or arm Q is connected to said upright and is adapted to be swung over and away from the track as de sired.

Directly above the duplex valve in the main valve casing is located the supplemental valve seat R, secured to the top of the casing and provided with the valve opening r, over which works the spring pressed relief valve S. The said relief valve S is provided with the depending guide flanges or plates s, working through the valve opening in said upper valve seat, and also with the rubber cushion disk s', having the rounded annular bearing face s2, adapted to rest upon the top of the valve seat R, and provide a vperfectly tight joint. The relief valve S is normally held to its seat by means ot' the spring T, bearing thereagainst and the cross head U supported above said valve and the valve seat by the opposite supporting rods V, having upper threaded ends 1J, receiving the adjusting nuts fu', Working over the opposite ends of the cross head engaging said upper ends, so as to provide means for adjusting the tension of the spring, so that when the Water in the valve casing is under undue pressure, the said pressure is relieved by means of said valve. -Now it will be readily seen that by operating the operating rod, the auxiliary valve d, is first raised to allow the water to pass through the main valve c thus relieving the main valve from the pressure of the water and allowing the same to be easily7 raised from its seat. Itwill be also seen, that by raising the operating rod H, to lower the valve stem D, the main valve is first closed, thereby diminishing the column of water, which enables the tank when nearly full to be readily filled without running over, the auxiliary valve cl of course closing subsequently, while the seating ot' both valves is rendered gradual and easy without any undue jar or concussion by means of the air and lwater cushion previously described, thus providing a stand pipe easily controlled and operated.

Having thus described my invention, what IZO I claim and desire to secure by Letters Patent is;-
