Our invention relates to means adapted to be secured to a locomotive whereby the inside faces of the balls of the rails, at curves in the track-rails, may be properly lubricated and thereby in turn also lubricate the throat or flange of the wheels of the locomotive and rolling stock.

Our invention has for its object the production of means whereby proper lubrication will be automatically induced through the swinging or lateral movement of the forward locomotive truck induced by a curve in the track-rails; the means. operating in such manner that a proper spraying of the lubricant onto the inside face of the ball of the rail at the outside of the curve will occur immediately forward of the wheels of the front truck of the locomotive.

The objects and advantages of our invention will be readily comprehended from the following detailed description of the accompanying drawing, wherein Figure 1 is a front elevation of a portion of a locomotive, with parts in section; showing our improved means applied thereto and in elevation. c

Figure 2 is a detail sectional elevation of the lubricant holding receptacle and the discharge controlling conduits.

Figure 3 is a detail sectional view of the valve mechanism; the view being taken substantially on the line 33 of Figure 1.

Figuretis a sectional view taken substantially on the line &4 of Figure 3.

In the particular exemplification of the invention as disclosed in the drawing, a lubricant reservoir or tankis shown at 10, of a suitable capacity and construction and pref erably attached in any convenient manner adjacent to the saddle or cylinder casting 11 of the locomotive or at a suitable point near the boiler of the locomotive, inorder that the lubricant or oil may beikept warm and therefore at a temperature which will constantly maintain its fluidity. The tank or reservoir 10 in the drawing is shown provided with an opening having a removable plug 12 to permit filling of the reservoir; the

plug or top of the tank beingprovided with a minute air ventor opening so as to permit Serial No. 310,484.

proper siphoning of the contents and avoid improper draining of the reservoir. Any suitable manner of fastening the reservoir may be employed, as for example by means of a suitable bracket as shown at 13.

The reservoir 10 is shown provided with a pair of suction tubes 14 which lead from a point slightly removed from the bottom of the reservoir toward the top thereof; curving outwardly through the sides of the reservoir Where the outer ends are connected to suitable T -couplings, as at 15, which are arranged in pipes 16 and 17 The section of each pipe 16 and 17 which enters the coupling 15 is provided with a reduced orifice or nozzle, as shown in dotted lines at 18 in Figure 2, and preferably disposed in alignment with the orifice of the tubes 14 so that the medium, air or steam which passes through the pipes 16 and 17, will induce suflicient pressure to cause the lubricant to be siphoned from the reservoir 10 and to be atomized and sprayed by the delivery ends of the pipes 16 and 17 onto the balls of thetrack-rails under certain conditions encountered in the track-rails.

The lower ends of the pipes 16 and 17 are each connected, preferably at opposite sides, to a valve casing or chambered member 19 which is shown mounted to the rear of the locomotive bumper beam 20; it being understood, of course, that any other suitable location ofthe valve casing may be employed where it will be properly positioned relative to the lubricant containing reservoir.

The valve casing or chambered member 19 is shown provided with ports 19, 19' with which the pipes 16 and 17 communicate, and

these ports in turn are provided with suitable valves 21, 21, which are preferably in the nature of poppet valves having the longitudinal side passages 22 at a point slightly removed from the enlarged heads 23 of the valves.

These heads normally seat at the upper end of the ports through the pressure of the pressure medium in the chamber of the member or casing 19. The ports are arranged in the valve casing 19 so that the poppet valves will be at aslight inclination or angle as shown in Figure 4 and for that reason the 2 shown slotted or bifurcated at 27, 2 7 to re-- closed against passage of the operating me-' upper surface of the body portion of the and thence intoreither of the'pipes 16'or 17 as the case may be and as hereinafter explained. V

The c0ver25 has an opening to receive a. "suitable pipe 26 which either leads to the air reservoir in the locomotive or which may lead to the'steam space or dome of the locomotive if so desired. y p v The valve casing 19 on its lower side is ceive the oppositely flared head 28 of a rocker arm 29 therebetween. The head 28 extends to opposite sides of the median line of the head and therefore also of the rocker arm 7 29, so that the 'ends of the head may be dis posed immediately beneath the lower ends of the poppetvalves 21. The arrangement is such that when the rocker arm is in vertical or normal position, no upward pressure on the poppet valves will be exerted and the poppet valves therefore will be seated or dium through the ports. I

We have shown the head 28 as preferably being made separate from the rocker arm 29 I and have therefore shown the head suitably secured tothe rocker arm by'means of the side plates 30, 30, see Figure 3, which are bolted, respectively, to the lower end of the head 28 and to the upper end of the rocker arm. The head 28, which is disposed between the bifurcations 27, 27 of the valve casing 19 is pivotally secured in place in any suitable manner, as for example by the bolt 31 which is disposed through the bifurcations of the valve casing from front to'rear so as to permit the head with the rocker arm to oscillate in a direction transversely of the locomotive. V a I The lower end of the rocker arm 29 is connected to a suitable bracket 32 secured to the swinging bolster 33 of the forward engine truck; the connection of the arm 29 to the bracket 32 being such that there may be relative up and down sliding movement between the arm 29 and the bracket while at the same time inducing the arm to swing about the The pipes 16 and 17, which are properly secured in place against movement, lead beyond the couplings 15 and extend down toward the truck-frame where each pipe .16 and V 17 is provided with a flexible tube or hose 34 for making flexible connection with the tubes 35, 35, which aresuitablysecured to the jour nal box as for example by means of brackets,

as at 36, so as to fixedly hold the tubes in place.

The tubes 35 have their lower ends bent outwardly toward the inside faces of the balls or heads of the rails 37, just forward of' the front wheels 38 of the locomotive sate for the up and down movement between the truck and the fixedly secured pipes 16 and 17.

reaches a curve in the track rails, causing the truck The flexible connections 34 compenv7 struck-frame to swing laterally, the arm -or lever 29 will likewise be swung about its pivot 31, thereby rocking the head 28 andcausing one of the poppet valves 21 to be moved up wardly off its seat. Movement of a poppet valve ofl' its seat will allow the pressure me-- dium, air or steamwhi'ch is in the cavity or chamber of the valve-casing belowthe cover 25, to flow past the poppet valveand into oneof the ports 19 and thence into the pipe connected therewith, either pipe 16 or pipe i i the poppet vvalve, namely the poppet valve shown to the left in Figure 4, off its seat and allow the pressure medium to enter pipe 16.; The medium flowing through the re duced orifice or nozzle, indicated in dotted lines at 18, will siphon a quantity of lubricant or oil from'reservoir 10, atomizing the oil'and spraying the same onto'the inside face of the ball of the rail on the outside of the curve, namely the rail to the right as viewed in Figure 1.

Movement of the truck-frame about a curve 2 toward the right as view'ed in Figure 1 will cause an opposite swinging movement of the truck-frame and therefore of arm 29 with its head 28 so that the end ofthe head to the right as-viewed in Figure 4 will move its poppet valve off its seat andallow the pressure medium to induce a siphon action through pipe 17 and therefore spray the oil onto the inner face of the ball of the outer rail to the left, asviewed in Figure 1. That is to say, the lubricant will be sprayed onto the rail and therefore onto the wheel fianges encountering the frictional wear'at a curve in the track-rails. I p

We prefer to mount the lubricant containing reservoir-at a point where it willbe kept sufliciently warm during cold seasons of the year sofas to maintain fluidity of the lubriv r c s0 With our improved meansit is apparent that, when the forward locomotive truck cant and have therefore shown the reservoir mounted adjacent to the saddle casting, although it is apparent that it may be mounted at a suitable point near the boiler of the locomotive. It is apparent that either air or steam may be used as the medium for siphoning the oil from the reservoir and spraying it onto the inner faces of the balls of the rails, depending upon the season of the year or the climatic conditions or zones in which the locomotive is operating.

By spraying the lubricant onto the inner faces of the balls of the rails, immediately forward of the front wheels, it is evident that the throats or flanges of the wheels will like wise be lubricated in their contact with the inner faces of the rails and that wear and tear on the wheel flanges as well as on the rails will be greatly reduced.

Through the use of our improved means, a material saving in fuel will also be obtained by reason of the reduction of the wheel-flange friction encountered on a train of cars.
