POLING DEVICE FOR RAILROAD-CARS.

Application filed January 2'7, 1915.

To all whom it may concern:

Be it known that 1, Russian. ARTHUR, a citizen of the United States, residing at Erwin, in the county of Preston and State of West Virginia, have invented certain new and useful Improvements in Poling Devices for Railroad-Cars; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which-it appertains to make and use the same.

This invention relates to an improvement in devices for poling railroad cars, and is especially designed for use on switchingengines in railroad yards, when it is desired to move a car which is positioned upon a side track alongside the track upon which the engine is traveling.

The primary object of this invention is to provide a poling device as specified, which includes a pivoted pole having an enlarged head formed upon its outer end, for engagmg the car to be moved or poled, and to connect the inner end of the pole to a gear which is rotated by the longitudinal movement of a rack bar for moving the pole into or out of operative position. 7

Another object of this invention is to provide pneumatic means for operating the rack bar for moving the pole into or out of operative position, which pneumatic means may be operated by a person standing upon the platform of the tender of an engine.

A still further object of this invention is to provide a novel set of valves interposed in the pneumatic apparatus for operating the rack bar, which valves control the passage of air into and out of cylinders for operating the rack bar.

With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail ref erence will be had to the accompanying drawings wherein like characters designate like or corresponding parts throughout the several views, and in which- Figure 1 is a plan view of the improved poling attachment, showing the same attached to a fragment of the tender of an engine, Fig. 2 is a top plan view of the device, Fig. 3 is a fragmentary vertical section Specification of Letters Patent.

through the device, Fig. 4 is a detail vertical section through the valves, Fig. 5 is a cross sectional view on the line 55 of Fig. 4, F 1g. 6 is a cross sectional view on the line 66 of Fig. 4, and Fig. 7 is a side elevation of one of the valves used in the construction of the poling device.

. Referring more particularly to the drawings, l designates the tender of an ordinary locomotive engine, which has a sill 2 extending transversely from the upstanding sides of the tender.

The sill 2 of the tender 1 has secured to one side thereof a bracket 3, which bracket is composed of a horizontal arm or plate 4 and a vertical plate 5. The horizontal plate 4 is provided for resting upon the upper surface of the sill 2, while the vertical arm engages the outer edge of the sill, as is clearly shown in Fig. 3 of the drawings.

The horizontal plate 4 has a vertical stub shaft 6 secured thereto, adjacent its rear end, upon which stub shaft is rotatably mounted a gear 7. The gear 7 has ears 8 and 9 formed thereupon and extending outwardly from the periphery of the gear, which ears are spaced from each other and have pivotally connected thereto, and positioned between their facing sides, a pole 10. The pole 10 has an enlarged head 11 formed upon its outer end, which head has its outer end concaved, and its inner end cut diagonally for forming points 12, as is clearly shown in Fig. 1 of the drawings.

A rack 18, is slidably carried by the plate 4 and its teeth mesh with the peripheral teeth of the gear 7, for rotating the gear upon longitudinal movement of the rack bar 13. An idler or guide wheel 14 is rotatably mounted on a vertical upstanding stub shaft 15, and it engages the rear side of the rack bar 13, forming a guide for the movement of the rack bar for keeping the teeth formed thereupon always in mesh with the peripheral teeth of the gear 7. The guide wheel or roller 14 has a flange 16 formed upon its upper edge, which engages the upper surface of the rack bar 13, for preventing vertical communicating with its forward and rear ends respectively. The pipes 19 and 20 extend rearwardly along the upper surfaceof the plate 4 and communicate with a valve structure 21. The pipe 19 communicates with one side of the valve casing 22 of the valve structure 21, and the pipe 19 communicates with the valve casing diametrically opposite to the communication with the valve. casing of the pipe 20. The valve casing 22 has a rotary valve core 23 positioned interiorly, thereof, which valve core is provided with a pair of arcuate ducts 24 and 25. The ducts 2,4 and 25 form substantially a quarter of a circle in plan, and they curve oppositely, so that when the duct 24 is in communication with the pipe 20, it will also be in communication with the inlet opening 26 of the valve casing, for permitting of the passage of air throughthe duct 24, the pipe 20, and into the rear end of the cylinder 17. Wherrthe duct 24 is in communication with the inlet 26' and the pipe 20, the duct 25 will be imcommunication with the pipe 19 and anexhaust opening 27, which communicates with the, atmosphere, so as to permit of the escape of air from the cylinder li', formerly ofthe piston 18. .lVhen the valve core 23 is rotated so that the duct 25will have communication with the inlet 26 and with the pipe 19, the duct 24 will be positioned for communication with the pipe 20 and the exhaust 27, so as to permit of the escape of air from the cylinder 17, rearwardly of the piston 18, when the piston is in its outward position, and being forced rearwardly by the pressure of the air entering the cylinder through the pipe 19, utilizing the single valve structure 21 for controlling the inlet and exhaust of air into and from the cylinder 17. The valve casing 22 has communication withan air storage tank 28 by means of a pipe 29, which communicates with the inlet 26.

The side or vertical plate 5 of the bracket 3, has. a vertically positioned cylinder 30 carried thereby, in which is slidab'ly mounted a piston 31. .The piston 31 has a piston rod 32 connected thereto, which extends upwardly out of the upper end of the cylinder 30, and has a cross bar 33 mounted upon its upper end: The crossbar 33 1s posltloned, as is clearly shown in Fig. 1 of the drawings,

' for engaging the pole 10, and moving the same upwardly uponits pivotal connection with the ears8 and ,9, for raising or lowering the head 11 of the pole for properly engaging acar to be poled.

The cylinder- 30 has an air pipe 34 conimunicating with the lower end thereof,

which pipe communicates with a valve casing 35. The valve casing 35 has a vertically movable valve core 36 positioned therein. The valve core 36 is provided with a transversely extending duct 37, which extends entirely across the diameter of the core, and a second duct 38, which extends across the radius only of the core and has communication with the duct 36 by a vertical duct 35). The valve casing 35 has an inlet opening 4-0 formed therein, which has communication with the air storage tank 28 by means of the pipe 41, and a second opening 41 formed therein diametrically opposite of the opcnin g 46. The opening 41 has communication with the pipe 34. An exhaust opening 42 is also formed in the casing and is positioned directly beneath the opening 41. When the duct 37 is in communication with the inlet 40, it also communicates with the pipe 34 through the opening 41, which permits of the passage of air through the valve and into the cylinder 30, for forcing the piston 31 upwardly, for moving the pole 10 upon its pivot connection with the ears 8 and 9. hen the valve core 36 is moved downwardly, for cutting off the passage of air from the storage tank 28 into the cylinder 30', the duct 38 communicates with the pipe 3.4, and with the exhaust opening 42, through the duct 37, which permits of the exhaust of the air from the cylinder 30, and allows the piston 31 to fall downwardly within the cylinder, by gravity or its own weight. g

The valve core 23 has a valve stem 44 secured thereto and extending upwardly out. of the valve casing 22, to which stem is pivotally connected a lever The lever 45 has a handle 46 formed upon one end. The end of the lever 45 opposite to the one upon which the handle 46 is formed, is scated in a slot 47, formed in a p'late The plate 48 is secured toor formed upon the upper end of the valve stem 49, which is connected to the valve core 36 andextends upwardly out of the upper end of the valve casing 35. The end of the lever 45 being seated in the slot 47, will permit of a horizontal movement of the lever, for rotating the valve core 23, without acting upon the valve core 36. hen it is desiredto operate the valve core 36, for controlling the passage of air into the cylinder 30, the lever 45 is moved vertically upon its pivotal conncction with the valve stem 44, which will raise or lower the valve core 36, depending upon the direction of movement of the lever. v

In the operation of the improved poling device heretofore described: \Vhenit isdesired to pole a car, the valve core 23 is operated, by the rotating of the. same by means of the lever 45, which will permit of the passage of air into the cylinder 17, through the pipe 19 which will force thepiston 18 outwardly within the cylinder, and move the rack bar 13 to. the position illustrated in dotted lines in Fig. 1 of the drawing, which will rotate the gear 7 and move the pole 10 to a transversely extending position with respect to the engine tender 1, and position the head 11 'for engagement with the car to be poled. In case the head 11 of the pole is not high enough for proper engagement with the car to be poled, the valve core 36 is operated for permitting of the passage of air into the cylinder 80, which will move the piston 31 upwardly and through the engagement of the head 33 with the pole 10, move the pole upon its pivotal connection with the ears 8 and 9, or move it substantially in a vertical manner, for raising the head for properly engaging the car. After the car has been poled, to the desired position, the lever as is operated, for forcing air into the cylinder 17 through the pipe 20, which will permit of the exhaust of the air from the forward end of the cylinder, in the manner heretofore described, and will force the piston 18 forwardly within the cylinder, moving the rack bar inwardly and consequently moving the pole 10 inwardly, by the rotation of the rack, to the position indicated in solid lines in Fig. 1 of the drawings.

From the foregoing description taken'in connection with the accompanying drawings the advantages of construction and of the method of operation of the improved poling device will be readily apparent to those skilled in the art to which this invention appertains and, while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construction, combination and arrangement of parts may be altered to suit practical conditions provided such alterations are comprehended within the scope of what is claimedl hat is claimed is 1.
