1'0 (LIL whom it may concern:

Be it known that we, ELIJAH STERLING Guns and HARRY Rooonus ROMBERGER, citizens of the United States, residing at Winona, in the county of Montgomery and State of Mississippi, have invented certain new and useful. Improvements in Means for Oiling. Tracks and Applying the Air-Brakes for Stopping Railway-Trains; and we do hereby declare the following to be a full,clear, and can act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

For neutralizing the traction power of the locomotive-engine of a railroad-train and for stopping the train we provide means 0 erated by a track device which is operate by the movement of the train for effecting a flow of oil upon the to of the rails in front of the drivers and by t e same means which effects the oil flow to cause the brakes to be partially applied to destroy the momentum of the train, and while the slipping of the drivers will be effective to stop the train the conjoint effect of the oil-flow and applying the air-brakes will conduce to greater eii'ctiveness and safety Without the intervention of the engineer who from any cause may be incapacitated to act on the showing of the den er-signal. 7 Tile design of our invention is to make the en ineer more careful, and in the event of his failure to note the signal then the movement of the train will bring into action means for causing the oiling of the rails in advance-of the drivers in conjoint cooperation with means for automatically 0 crating the airhrake lever to apply the rakes. In this combination a track device, means for delivering a flow of oil on the rails to cause the driving wheels to slip, and means for app ying the brakes are caused to be operate by the movement of the train, the track device being operated from the block-house and is connected with and operates the signal, while the attachments for oiling the rails and for applying the brakes are carried on the front 0 the locomotive and connected to ether for operation by the track device. hen the train has been stopped, the engineer can cut oil the flow of oil and restore the oil-feeding mechanism and the air-brake-lever connections to their normal positions. We attain these objects by the mechanism illustrated in the accompanying drawings, in which--v V Figure l is a side view of so much of a locomotive-engine as shows those parts of our invention, including an oil-tank and a depending arm at the pilot, whereby the oil is caused to be fed to the top of the rails and the connections from the oii-feed-operating parts to the air-brake lever, whereb the brakes are caused to be artially app ied'at the same time and by t e same means, including said pending arm, and a fixed track device wherep y said pending arm is operated by the movin train. Fig. 2 shows in erspective the oi -tank and its valve-control ed feeding connections, includin the train de ending arm which is operateifiiy the track dhvice. Fi 3 is a vertical cross-section of the oil-tan showing its valve-controlled connections in the closed positions of the valves. Fi 4 shows the friction-clamp by which the va veoperating rock-rod is automatically held when rotated to hold the valves open to allow the feed of the oil. Fig. 5 shows a portion of a railroad-track, the track-impact de-' vice, its connected rock-rod leading 'to the block-house, the signal device, and its operative connections with the track-impact device, and the block-house connections whereby the impact device is set to o erate the depending arm in connection wit the dangersignal. Fig. 6 shows the track rock rod blockhouse connection. Fig. 7 shows the track rock-rod impact-arm and the abut ment for supporting it against the impact of the depending arm of the locomotive. Fig. 8 shows in top view the track reek-rod and its impactarm in its h orizontal position in which the si nal indicates safet We ave shown the usu'a SWIIIgiHg'PIVOtGQ we' hted sema hore mounted on a 0st 1 an connected a wire cord 2, by w ich it is set to show t e danger-light and which is connected to and operated'ny a crank-arm 3, connected to and o erated by a ground or track rod 4, mounts in fixed bearings and extending from the track to the station or block-house, where it is provided with suitable connections by which the attendant will cause said ground or track rod\to be rocked on its bearlngs while at its other end said ground or traclr rod has an impact. arm or crank 5 at the'side of the track whereby it may be raised to a vertical osition when the signal is set to show the ianger-li 'ht or in horizontal position when the signs is set to show safety," It is this arm or crank 5, when set vertically, that receives the impact of an arm 6, depending from the engine frame, that causes the automatic 0 eration of means whereby oil is fed to the rai sof the track and at the same time causes the air-brake lever to be operated to apply the brakes, both means coacting to stop the train and actuated by the same connections independently of the engineer.

or feeding the oils. tank 7 is mounted, preferably, in front of the pilot on the under side of. the en ine-frame 8, and is provided at each end wit a pipe 9 9, which terminates to deliver oil upon the to of the rails 10 to cause the slipping of the rivers of the locomotive. Avalve-case 11 is suitably connected with each pipe, the stem 12 of the valve rising at the rear side of the tank and has a jointed connection with the end of a horizontal arm 13, which rigidly connects with a horizontal rock-rod 14, mounted in bearings at the top of the front beam 15 of the engineframe. At one end this rock-rod has the arm 6 depending at the end of said beam beyond the side of the pilot and in the path of the track impact arm or crank 5, so that in the raised position of this crank-arm it will be struck y the dependin arm of the moving train, thereby forcing t e depending arm to swing back and causing it to pass overthe track impact-arm. ThlS movement of the depending arm will cause its connected rod 14 to be rocked, thereby causin its horizontal arms 13 to be lifted and with t cm the valves and allow the oil to fiow from the tank throu h the feed ipes upon the rails. A simp e means for olding the valves open is by friction, and for this purpose the bearing-supports 16 for the rock-rod 14 are formed by fr1ction-' clamps, each clamp having a tighteningscrew 17 to give more or less friction upon the rod to prevent it from turning except by force, the friction being suflicient to overcome the weight of the valve connections and the tendency of the depending arm to assume its normal vertical position. These frictionclamps also serve to hold the de ending arm and the valve connections in t iieir normal positions. v i i It will be understood that the impact of the, depending arm againstthe track impaet-' arm will cause the rock-rod on theengine,- frame to be turned in a forward direction, and this turning of the rod is utilized to actuate the air-brake lever to apply the ,brakes simultaneously with. oiling the rails, and for thispurpose a ull-rod 18 connects a lug 19 on the rock-r0 14 with an arm 20 of the airbrake lever 21 in the engine-cab, said pollrod -extending;along the outside of the engine, so that t e turmng of the rock-rod, will a house or station this suitable connections applying of t cause said pull-rod to be drawn forward, am thus operate the brake-lever and cause the brakes to be applied. By these same connections the engineer can pull the rod, and thereby causes-aid rock-rod to be turned back, its valve connecting horizontal arms 13 to be turned down, thereby dep rcssiiu and closing the valves and stopping the l ow of the oil: Therefore while the impact track-arm is r the primary means of causing the feed of the oil and the applying of the brakes the engineer from his )osition in the cab can control the air-hrake ever in the usual way and cut oil the feed of the oil by the same means by which the trackimpact-arm causes the brakes to be applied.

It is important to note that the track impact-arm 18 caused to have a rocking movement of half a revolution from a horizontal to a raised position to receive the impact of the depending arm of the locomotive, and therefore the impact-arm must be firmly supported. For this purpose a fixed abutment 22 serves as a stop for the impact-arm in its raised position to limit its movement, and thereby control the setting of the danger signal by controlling the rocking of its connected groundrod. This abutment also serves to prevent the force of the impact against the impact-arm from endangering any ehan e in the position of the signal. At the b ockground or track rod has y which it is rocked to raise and to lower its impact-receiving arm,

; and which, as shown, ma consist of a vertical rod 23, having a hand e 24 and connected with the ground or track rod b a crank-arm 25, so that raising the hand-r0 23 will cause the partial rotation of the ground or track rod to raise its impact-arm against the abutment and to set the danger-signal, and for this purpose the si nal-connecting wire is referably connects to the crank-arm of t esignal-rod by a chain 26 to relieve the shock of the blow of the engine depending arm against the impact-arm of said rod. means may be used to hold the hand-rodin its raised position-such, for instance, as ratchet-teeth 27 on the hand-rod engaging a fioo'rlate.

A c ain 28 connects the air-brake pull rod with the brake-lever, so that the air-brake may be operated by the engineer without moving the pull-rod which connects with the oil-feeding mechanism. This chain may also be employed to adjust the extent of the.

movement of the pull-rod to partially ap ly the brakes by partially opening the bra evalve. i

The slippin of the engine drivers andthe e brakes will notify'the engi- Any suitable neer when he may cut off-the oil-supply and stop the train'as usual; but supposing there is no .e ear or fromany cause he may not see the: signal the oil continuing to-flow and the airsbrakes partially applied the train would be stopped. Therefore the engineer, acting on the signal, may at once a ply the brakes and stop the train and at t ie same time out off the flow of oil without disturbing the signal; but in a contingency in which the engineer may be aslee or dead when the train should be stopper then the flow of oil alone would effect this, while the air-brake connections would render this more effective and with comparative quickness.

The danger-signal and the track impactarm being connected and operated by the same means the track impact-arm will he raised in operative position when the dangersignal shows, and the engineer having observed the danger-signal gives notice thereof by the whistle that he will stop. Thereupon the bloek house operator turns down the impact-arm to a horizontal position and the engine passes without operatin the impactarm, and thus avoids a waste 0 oil or causing the'brakes to be applied by the movement of the train; butit is the purpose of our invention to provide two coactin causes rendered active to safel and quick stop the train without regard to the signal or to the engineer at all stopping-places, while placing the control of these causes under the block-house operator to render them inactive under notice from the engineer.

The track rock-rod may be suitably inclosed to protect it. Obviously the oil-feeding appliance may he usedindependently of the brakeoperating appliance.
