`RAILROAD WATER-COLUMN.

SPECIFICATION forming part of Letters Patent N 0. 763,063, dated J une 21, 1904.

Application filed September 21, 1903. Serial No. 173,938. (No model.)

To all whom t may concern:

Be it known th at we,ALBEnT K. MANSFIELD,

of Salem, in the county of Columbiana and State of Ohio, and GEORGE G. GUY, of Batavia, in the county of Kane and State of Illinois, have jointly invented a certain new and useful Improvement in Railroad Water-,Columns, of which improvement the following is a specification.

Our invention relates to water-columns or water-cranes for supplying water to thde tenders of locomotive-engines on a line of railroad of the class in which the water-supply valve is operated by hydraulic pressure.

The object of the invention is to provide, in connection with a valve of such character, means whereby it will be so supported and actuated as to be easily and effectively operated and its tight closure will be insured.

The improvement claimed is hereinafterv fully set forth.

1n the accompanying drawings, E1gure 1 1s a side view, partly in section, of a Water-column, illustrating an embodiment of our in-Y vention; Flg. 2, a View 1n elevation of theV with that set forth in Letters Patent of the United States No. 719,483, granted and issued to Albert K. Mansfield under date of February 3, 1903. As in said Letters Patent, a vertical stand-pipe l is suitably guided and supported, as, for example, through the intermediation' of antifriction-balls 45, on a tubular stand 2, fixed to a suitable bed or base adjacent to a line of railroad-track above a pit or subjacent space in which is located the casing 3 of a horizontally-moving water-supply valve 4, which casing 1s provided with a nozzle 5 at one of its ends for connection with a Watersupply main.. The stand-pipe l is open at each of its ends, and at and adjoining its lower end it is fitted to turn in a properly-packed stufling-box at the top of the water-supplyvalve casing 3. j

A horizontal delivery-pipe or gooseneck 7, the outer end of which is downwardly curved so as to present a horizontal discharge-opening and which may, if desired, rbe provided with a flexible discharge-pipe, is connected, with the capacity of movement in a vertical plane, to the stand-pipe 1 by a suitable joint formed at the upper end of the latter. The joint in the instance exemplified comprises a semicylindrical rocker 8, fixed to the inner end of the delivery-pipe 7, said rocker resting and turning on a semicylindrical seat or bearing 9, fixed to the top of the stand-pipe 1, as in Letters Patent No. 719,483 aforesaid. The overhanging weight of the delivery-pipe 7 is ,counterbalanced by a helical counterbalancespring 14, connected at its upper end to the deliverypipe and at its lower end to the standpipe 1.

YThe water-supply valve 4, which is of the lift or puppet type, is fitted to move horizon- 'tally toward and from a seat in the valve-cas- 3, and when closed upon said seat it is caused to make a water-tight joint therewith by a suitable packing-ring 4". A piston 4, connected with and of greater diameter than Vthe valve 4,'is fitted to traverse in a cylinder 4b vwithin the valve-casing and is caused to make a water-tight joint therewith by a packing-ring or cup-leather 4c. The inner end of the cylinder 4b is partially closed by an annular head 4, having a central opening of smaller diameter than the bore of the cylinder, this head being provided for the purpose of protecting the piston from the pressure of' thewater when flowing through the stand-pipe 1. A central hub or sleeve 4f, formed upon the pistou 4, is secured to the valve 4, and a cylindrical shell 4g extends from the valve to thepiston, said shell passand 'traverses with the piston and valve longitudinally on a pipe 30, the inner end of which is open to the supply-main nozzle 5 and is fixed in an open frame or spider 30u in the valve-casing. The pipe 30 passes through a head which closes the outer end of the cylinder 4b and is extended downwardly and inwardly, through the interposition of suitable return-bends or elbows, to a connection with the cylinder-head below its center, the end of the pipeopening into the cylinder 41. One or more drain-passages 32 lead from the cylinder 4b on the inner side of the piston to the exterior of the valve-casing; A regulatingcock 31, located in the pipe 30 exterior to the cylinder 4" and adjustable by hand, enables the flow of water through said pipe to be regulated as desired to effect the prompt closure of the supply-valve 4.

A controlling valve or cock 29 is fitted in the pipe 30 exterior to the cylinder 4b, said valve having an arm 28, through which it is operated, fixed upon one of itsends. The arm 28 is coupled by a rod or link 27 to the outer arms of a pair of double-armed levers 24, which are pivoted by a pin 25 on a stand 26, fixed to the top of the valve-casing 3. The upper or inner arms of the levers 24 carry upon their ends rollers 33, engaging a circumferential groove on a collar 34, which is fitted to slide vertically on the stand-pipe 1 and is coupled by rods 35 to arms 36 on a horizontal shaft 37, which is journaled on the delivery-pipe 7 adjacent to the rocker 8. The shaft 37 carries an upwardly-projecting arm 38, which may, as shown, be made integral with one of the arms 36, and the arm 38 is coupled by a rod 39 to an operating-lever.

40, which is journaled on the delivery-pipe 7 near its outer end, so as to be readily accessible by the fireman of a locomotive when it is desired to supplx7 water to a tender-tank. Upward movement of the operating-lever 40 will, through the connections above described, close the controlling-valve 29, whereupon the pressure in the water-supply mainand nozzle 5 will unseat the water-supply valve 4 and water will be supplied through the stand-pipe l to the delivery-pipe 7. W hen it is desired `to cut off the water-supply, the operatinglever 40 is moved downwardly into the position shown in Fig. l, thereby, through the connectionsdescribed, opening the controlling-valve 29 and admitting water through the pipe 30 to the left-hand side of the piston 4a. Said piston being of larger diameter than the water-supply valve 4, the pressure exerted upon the piston will move it to the right, closing the valve 4 and holding it seated so long as the controlling-valve 29 remains open. Water which may leak into the space at the right of the piston escapes therefrom through the drain-passage 32.

A drain-valve 41, which controls a dischargepassage 42 in the bottom of the valve-casing 3, is connected by a rod 43 with a stud on the inner arm of one of the levers 28, the drainvalve being opened by the downward movement of said arm in the closure of the controlling-valve 29 and closed by the upward movement of said arm in the opening of the controlling-valve.

It has been developed in practice that under considerable heads the water-supply valve i will sometimes be closed with undue and objectionable force, and we have therefore provided means for preventing such action, examples of which are illustrated in Figs. 4 and 5. As shown in Fig. 4, longitudinal slots 30" (or equivalently a plurality of holes) are formed in the pipe 30, terminating at such a distance from the seat of the valve 4 as to be gradually closed or nearly closed in and by the `closure of'the valve, and a perforated plug '30d is inserted in the end of the pipe adjoin- The perforation of theV ing the supply-main. plug 30l is of suiicient diameter to supply leakage past the piston 4, but not so large as to admit a sufficient volume of water to cause shock. The closing pressure on the left-hand side of the piston is opposed by the pressure of water from the supply-main admitted to its opposite side through the slots 30", which, as before stated, are gradually closed in the closure of the valve, the result being to effect an easy and quiet seating of the latter.

In the modification shown in Fig. 5 the valve and piston are separated one from the other and a spring 30c is interposed between and bears at its opposite ends against the valve and piston, respectively. A hub or sleeve 4h, which fits on the pipe 30, is vformed on the piston 4, and a similarly-fitting sleeve 4l is formed on the valve 4, said separate and unconnected sleeves being substituted for the single connecting-sleeve 4f, before described and shown. In operation the. closing force applied to the piston is transmitted to the valve through the spring 30, and being largely absorbed by the resistance of said spring the valve is caused to seat quickly and without shock. The slots and perforated plug shown in Fig. 4 may, if desired, be used in connection with the separate piston and valve above described to effect very quiet closure.

Fig. 5 also illustrates a modified form of controllingvalve. The pipe 30 in this instance terminates at the outer end or head of the cylinder 4, and a valve-casing 29d is secured to said head and surrounds the open end of the pipe 30. The interior of the valvecasing 29d communicates with the cylinder 4b by ports 29C, and communication between said cylinder and the pipe 30 is governed by acontrolling-valve29, which is of the` lift or puppet type and works between two seats, one at the end of the pipe 3() and the other in the valve-casing 29. The valve 29 is normally held to the latter seat by a spring 29", thereby establishing communication between the pipe 30 and cylinder 4b and admitting pressure to IOO the left-hand side of the piston 4", by which the water-supply valve 4 isheld to its seat. Vhen it is desired to open the water-supply valve 4, the controlling-valve 29 isshifted so as to seat at the end of and close the pipe 30 and to release pressure from the left-hand side of' the piston 4 through the ports 29 to the exterior of the cylinder, whereupon the pressure in the supply-main will unseat the water-supply valve and supply water to the delivery-pipe, as in the instance first described. The seating of' the controlling-valve -to perform this function is effected by means of a bell-crank lever 28, which is pivotedlon the valve-casing 29d in position to permit its lower arm to be pressed against the stem of the controlling-valve, and its upper arm is coupled to a vertical rod or stem 27. The stem 27 is adapted to be raised by a double-armed lever 24, which is pivoted by a pin 25 to a stand 26, fixed on the top of the valve-casing 3. The outer end of the lever 24 is coupled to the stem 27 through theintermediation of' aspring 27h, and theinner ends are provided with rollers which engage a circumferential groove in a collar 34, fitted to slide on the stand-pipe 1 and connected to an operating-lever 40, as in the instance first described.

The stand-pipe l may be moved out of and into its normal position-a1 e., that in which the connected delivery-pipe 7 stands parallel with the railroad track-by any suitable known means-as, for example, a hand-lever 46, pivoted to the stand-pipe above the tubular stand 2.
