I 3 Claims.

This invention relates to means for lubricating wheel flanges and rails and more particularly to a means for lubricating theselelements operated by movement of the, locomotive and cars over 5 the rails. I 1

As is well known to those' familiar with the art, the rails of right-of-way' have verticalmovement with the cars passing thereover. This vertical movements is not ,only a general movement :of the rails and for supporting ties, but likewise a relative movement of the rails with relation to the ties. This movement is'always present in the rails and is noticeablein a,1freshly spiked rail immediately afterthe passage of a heavily loaded train thereover. 1 l

An important object of the present invention is the utilization of this vertical movement of the rail to cause operation of ameans for supplying lubricantfor lubricating the flanges of the wheel and thus transmitting the lubricant to the side faces of the rail balls forconsiderable distance in the direction in'which the train is travelling.

I A further and more specific object of the invention -is to provide apparatus of this character,

which may beoperated by the movement of the rail with relation to the ties, thus permitting storage tanks, pumps and associated mechanisms to be attached to theties and thus securely anchored. I A further object of the invention is to provide means of this character whichwhen applied to the rail strengthens the same insteadof reducing the strength thereof. h a

A still further object of the inventionis to produce an apparatus ofthis character which with but a slight modification of a rail which maybe producedin any railway shop, may be applied to the present railway systems, and which may be very readily and cheaply manufactured.

These and other objects I attain by the construction shown in the accompanying drawings wherein for the purpose of illustration I have.

my invention ports, such as ties or the like, and 11 arail supported thereby. This rail, in; accordance with my invention, is'ofisetjoutwardly, for a: desired length, as indicated 'at 1'2. Arranged in opposition to the inner face of the rail and seating 'at'its lower end .upon the base 1 3--thereof, is a; plate 14- of approximately thesamele'ngth as the oifset portion of the rail; This plate' is bolted to the rail, as indicated at 15 the-bolts 15 preferablypassing through a filler. plug, 15a arranged between the plate and rail and a gasket-,el-darranged between the inner face ofjthe filler plug and rail.

Characteristic elevations of-the filler plug and gasket are shown. in Figure 5 andit will be noted that'these-elements combinewith the plate and rail to produce beneath thehead of the rail at the inner face thereofa; chamber C. The inner face of -the. pl ate has shallow vertically extending depressions. formed therein, as indicated at 17,:the'se'depressions, when the plate is in applied position, -forminga'channels forzthe passage of lubricant fromjthecham'ber C through its upper edge and in proximity to the side face of theball .Ofthe rail.

Thefupper edge of the plate is, located slightly below-the upper surface-of the ball, of the rail, and the outer face of the ,plate at its. upper edge is beveled, as indicated at 18, so that it is disposed at an angle tothe vertical slightly greater thantheangle ofthe'inner face of the flange F of a car wheel W. The body of the plate has formed therethrough openings 19 for connection with lubricant supply conduits 20.

In combination with apparatus of the character just described I employ an oil delivery mechanism, comprisinga tank 24, a pump 25,.and operating means for .thepump generally designated at. 2 6. The. pump 25is at present shown "as a simple displacementfcylmder, the intake and exhaust check valves, of which indicated at 27 and 28 are spring seated and are included in the connection 29 of the pump with the tank, and in the connection 30 with the oil delivery conduits 20. Conduits 20 should include a flexible section. Tank 24 should be provided with a capped inlet pipe 30, as this tank is intended to be embedded in the ground, and the pump casing should be enclosed within a housing 31, having a removable cap 32 for the same reason.

The operating mechanism may be of any suitable character which permits operation of the pump by the movement of the rails resulting from a train passing over the track. I, however, prefer the construction herein illustrated, which includes bracket elements 33 rigid to the pump and secured to the ties, as at 34. Upon the bracket element 33 I mount standards 35 and 36, the upper ends of which are pivoted levers 3'7 and 38. The adjacent ends of these levers over-lap one another and are provided with a series of longitudinal spaced openings 39 for the passage of a pivot bolt 40. h r p The connection with lever 37 to its standard permit longitudinal shifting movement of the lever, the pivot for the lever projecting through a slot 41 formed therein. The outer end of this lever 3'7 is connected to link 42 aiidto the piston 43. The outer end of lever 37 is forked to receive a horizontal flange 44 formed upon one element of a clamping bracket 45 adapted to clampingly engage the base of the 'rail. 7

One arm of the fork has directed therethrough a set screw 46 engaging one face of this flange, thus forcing a fulcrum 47 formed on the opposite arm into engagement with the opposite face of the flange.

In operation of the device during passage of each wheeloIver the tall, a slight depression of thisrail results, which through the leverage is transmitted to. pump piston 43, causing reciprocation thereof. Each operation of the pump causes a small quantity of lubricant'to-be de-' livered to thec'han'iber C from which it passes through openings 17 to the upper edge of the plate. At this point, "it is picked up by the flanges of the wheels and distributed along the side faces of the rail balls as the train proceeds.

Due to thedisposition of the upper edge. of the plate below the upper surfaces of the ball of the rail, very little, if any, of this lubricant reaches the ball of the rail, and-due to the fact that there is no contact of the railwhatever with the upper edge of this plate, there is no tendency of the opening 17 to close as a result of the spreading of the metal of the rail ball. Application of the plate does not 'in any way weaken the rail, and as a matter of fact, adds to the strength thereof.

Tests of apparatus constructed in accordance with my invention have indicated that the lubricant is distributed along the right of-way for a distance as "great as two miles from the point of its application, thus rendering the device extremely valuable for usein hilly country where the tracks usually abound with curves and are difficult of access.

In use of the apparatus in hilly country where its use is most generally necessarmit will be obvious that under manycircumstances the inclination'of the track will be such that there will be a tendency of the grease to collect at one end of the compartment At this end the filler plug .15a and gasket 16 are constructed'with longitudinally spaced vertical extensions 48 and 49, which combine to produce partitions within the compartment C, sub-dividing the same into a plurality of lesser compartments. The extensions 49 of the filler plug align with the oil inlet conduits 20 and have ports 50 connecting these inlets with longitudinally extending pipes 51 directed through the extensions 49, so that the lubricant is distributed to the compartment sections formed at opposite sides of the partitions.

Means may likewise be provided for collection of excess oil which passes down the outer face of plate 14 for its return to the tank 24. In

the present instance I have shown the outer face of this plate as provided with downwardly converging ribs 52 directing such excess oil into receiving pans 53 which are connected by drain pipes 54 with tank 24.

Since it will be obvious that the construction employed may be modified to a very considerable extent without materially departing from the spirit of the invention, I do not limit myself thereto except ashereinafterclaimed.
