SPECIFICATION forming part of Letters Patent No. 490,666, dated January 31, 1893.

Application filed September 28, 1891. Serial No. 407.084. (No model.)

To all whom it may concern.-

Be it known that I, HIRAM D. LAYMAN, a citizen of the United States, residing at Little Rock, in the county of Pulaski and State of Arkansas, have invented certain new and useful Improvements in Automatic Railway Pumping Machinery; and I do declare the following to be a full, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, which form a part of this specification.

My invention relates to mechanisms for operating railway pumps; the objects in view being to provide a mechanism of cheap and simple construction, adaptedto be located at one side of a track and to be operated by the wheels of the passing trains.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings:Figure 1 is a plan of mechanism, located at one side of a railway track. Fig. 2 is a vertical transverse section through the mechanism and track. Fig. 3 is a detail in elevation of the train-engaging loop oreye. V

Like numerals of reference indicate like parts in all the figures of the drawings.

1 1 designate the usual track-rails, which are mounted upon the ordinary ties 2, and at the side of the track there is located the watering-tank or reservoir 3, having the discharge 4. Adjacent to the tank and rails, in a well 5,a water-box 6 is located, the same constituting a pump-head, and from the upper side thereof extendsa discharge-pipe 7 which at its point of communication with the head 6 is provided with an upwardly-opening valve 8. The remaining end of the pipe 7 communicates with the tank 3. Depending from the under side of the head 6 are the pumpcylinders 9, in which are mounted for reciprocation the plungers l0, pump-rods 11 depending therefrom, and having their lower ends pivoted as at l2to awalking-beam or lever 13. This lever 13 is fulcrumed at 14, be-

lever are connected by a rod 21.

tween the pivots 12, upon any suitable support as 15.

In bearings 16, located at one side of the well 5, a transverse shaft 17 is mounted for rotation, the outer end thereof being provided With a small gear 18, and the inner end with a crank-disk 19, having acrank-pin 20located directly over the well, and above the free end of the lever or beam 13. The crank-pin and Each of the pump-cylinders 9 is provided with an upwardly opening valve 22.

A pair of vertical standards or posts 23 is let into an opening or cavity 24, formed in the ground between the Well 5 and the track, and it is upon one of these posts 23 that the outer bearing 16, for the accommodation of the shaft 17, is formed. The posts 23 are also provided with bearings 25, and in these is mounted a transverse shaft 26, which spans the cavity or hole 24. Upon this shaft a large gear 27 is mounted, the same being loose and adapted to permit of independent movement by the shaft. At one side of the gear 27 upon the shaft 26 there is mounted fixedly upon the shafta ratchet-Wheel 28, and a looselypivoted pawl 29 is located upon the face of the gear 27, and adapted to engage the aforesaid ratchet-wheel when the latter with the shaft is moved in one direction.

30 designates a re-winding drum, and secured to the same and wound thereon is the re-winding cable 31, to the free end of which a weight 32'is secured. At one side of the rewinding drum 30 and upon the sameshaft 26 there'is also mounted a main drum 33, around which is wound a cable 34, having one of its ends secured thereto. the cable is carried parallel to the tracks for a short distance, and subsequently passed around a sheave or pulley 35, which is mounted upon a vertical shaft 36 at one side of the track. The cable 34 is then passed through a guide-eye 37, which is located upon the end of a tie and finally terminates in an eye or loop 38. This eye or loop, as best shown in Fig. 3, is provided with a pair of lugs or ears 39, through which a bearing-bolt 40 is passed. Upon this bolt a roller 41' is mounted for rotation, and the same is designed to travel The remaining end of the ends of the series of ties along a track-bar 42 which is located upon outside of the track-rails 1. This track-bar has its forward end outwardly curved as at 43, or in other words 1s diverged from the track-rails.

In operation, the bar 44 is projected from any part of the moving train, traveling in the direction of the arrow, and engaged with the loop 38, when the same is located at about the eye 37. In this manner the cable is carried forward, unwinding itself from the drum 35:, rotating the latter the shaft 26, the re- Wmdmg drum 30, and thus winding up its cable 31 thereon, rotating the ratchet-wheel 28, and through the medium of the gear 27 turning the gear 18, shaft 17, wrist-plate or disk 19, vertically oscillating the rod 21, and thus actuating the pumps, so as to force water through the'same into the water-box 6 and from the water-box to the tank. As the cable is advanced by the bar 44, the roller 41 rides againstthe track-bar 42 until it reaches the curved end 43 by which it is deflected away from the bar 44 and out of engagement therewlth. When this release takes place, the pumps stop working and the Weight 3.2 acts 1n a reverse direction upon the shaft 26, the gear 27 remaining idle and the cable 34 returned to its wound position upon the main drum 33.

In some localities, where snow and ice are prevalent, the same would render the trackbar 42 and the roller 44 inoperative, 0r ineffectual for the purpose in view; and in such instances I place the roller upon the under s de of the loop 38, as indicated by dotted l nes 1n Fig. 2, at 45, and secure to the upper side of the aforesaid loop a vertical trolleyarm 46, the upper end of which is supplied with a trolley-wheel 47, which runs upon a.

track-bar 48, similar to the bar 42, or a suitable wlre. The track-bar 49 employed in this connectlon, is of L-shape, or horizontally-disposed, having its vertical flange secured to the ends of the series of ties 2. The remainder of the construction is the same as heretofore described, and the operation is identical.
