LUBRICATOR.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed April 4. 1906. Serial No. 309,861.

T0 all whom it may concern.

Be it known that l, EUGENE E. KEEFE, a citizen of the United States, residing aty Bellows Falls, in the county of lVindham and State of Vermont, have invented a new and useful Lubricator, of which the following is a specification.

This invention relates to lubricators; and its object is to provide a device of this character for applying lubricant to the flanges of car-wheels while the car is passing around curves, so as to prevent the flanges from chipping or grinding during said movement.

Another object is to provide a lubricator which will only operate while the car is on a curve, said operation being automatic.

A still further object is to provide a lubri cater which is normally out'of contact with the car-wheels and which is applied thereto when the car moves on a curve.

Another object is to provide means for preventing the admission of dirt, &c., into the lubricant-receptacle during the operation of the device and to regulate the discharge of lubricant from the receptacle.

lith the above and other objects in view the invention consists of a receptacle which is slidably mounted on guide-rods and carries a distributing-wheel which is normally supported close to but out of contact with the flange of one of the car-wheels. A rocking lever is mounted adjacent the receptacle and is adapted to be actuated by the lateral movement of the car body while passing around curves, said rocking movement causing the distributing-wheel to move into contact with the fiange of the car-Wheel and to be rotated by frictional contact thereon. This rotation will cause the distributingwheel to remove a portion of the lubricant from the receptacle and apply it to the flange of the car-wheel as long as the car is upon the curve. Adjustable means are located within the receptacle for preventing dirt from passing into the lubricant-receptacle from the distributing -wheel and also for regulating the discharge of lubricant from the receptacle.

The invention also consists of certain other novel features of construction and combinations of parts, which will be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings, Figure 1 is a side elevation of a truck having this improved lubrie eating attachment mounted thereon, a portion of the car-body being shown in position thereabove. Fig. 2 is an enlarged section on line a: a: of Fig. 1. Fig. 3 is a section on line y y' of Fig. 2. Fig. 4 is a front elevationof the receptacle and buffer-spring, the actuating-rod being shown in section. Fig. 5 is an enlarged section through a portion of the rear of the receptacle and showing the adjustable feed-rocking device. Fig. 6 is an end elevation of the rocking lever on its standard and showing the relative positions of the operating-rod and the guide-rods, one of the positions of the rocking lever being shown by dotted lines. Fig. 7 is a detail view of the rocking lever, and Fig. 8 is a similar viewof the head on the operating-rod.

Referring to the figures by numerals of reference, l is a car-truck of any suitableconstruction, and 2 represents car -Wheels by which it is supported in the usual manner. Astandard 3 is mounted on the truck and has a base 4, which is clamped thereagainst by means of a bolt 5 or in any other desired manner, it being necessary that the standardbe veryrigidlysupported upon the truck. Said standard has a head 6, provided with laterally-extending gears 7, which are formed with parallel sleeves 8, in which are securely fastened guide-rods 9, which are parallel and extend, preferably, at right angles to the standard 8 and to points adjacent the upper portion of one of the wheels 2`. j These rods are preferably adjustably mounted within the sleeves and are held against displacement by set-screws 10.

Extending upward from the standard 3 and its head 6 is a stem 11, having 'oppositely-extending guide-arms 12 at a point adjacent its lower end, said guide-arms being disposed at right angles to the guide-rods 9. The upper end of the stem is reduced to formv a flat ear 13, which projects into a recess 14, formed within the head 15 of a lever 16. The forked portion of this lever straddles the stern 11 and arms 12, and the free ends of the fork have parallel cam- faces 17 and 18, the face 17 IOO being convex and the face 18 concave, asx

is also disposed on the rod 19 and has a roller 23 thereon which bears against the convex face 17, said head 2O and roller 23 being spaced apart a distance equal to the distance between the two faces 17 and 18.

The rod 19 has an enlargement 24 at one end, which projects between and is secured to ears 25, extending forward from the central portion of a bow-spring 26, which embraces one end of a receptacle 27 and is secured to the sides thereof in any desired manner. This receptacle is slidably mounted on the guiderods 9, which extend through the ends thereof. Suitable packing 23 is arranged upon the ends of the receptacle where the rods extend therethrough, so as to prevent leakage of lubricant at these points. Tubes 29 are loosely mounted on the rods 9 and within the receptacle, and each of these tubes supports a sleeve 30. These sleeves constitute bearings 'for trunnions 31, extending laterally from the center of a feed-wheel 32. This wheel has an annular groove 33 in its periphery and is provided at opposite sides of. the groove with annular flanges 34 and 35, the peripheries of which are at different distances from the center of the wheel. Wheel 32 projects a short distance through a slot 36, formed in the bottom of the receptacle 27, and secured within the receptacle at opposite sides of the wheel is a false bottom 37, under which are slidably mounted L-shaped clamping-plates 38, the upstanding portions of which are held in contact with the faces of the wheel by means of coiled springs 39, which are mounted on stems 40, extending inward from the sides of the receptacle. A suitable number of stirring-blades 41 extendlaterallyfrom the wheel and are for the purpose of agitating the lubricant while the wheel is revolving, so as to keep it thoroughly mixed. r

A scraping-block 42 is slidably mounted upon the bottom of the receptacle adjacent the front end thereof, and one end of this i block is shaped to nt within the groove 33 of wheel 32 and upon the flange thereof. Said block therefore prevents dirt or other undesirable accumulations upon the outer portion of the wheel 32 from passing into the receptacle 27 and mixing with the lubricant. This scraping-block 42 may be adjusted by means of a stem 43, 'which is threaded thereinto and is swiveled in the front wall of the receptacle 27. The upper end of this stem has a head 44 to facilitate its manual rotation.

The rear wall of receptacle 27 is beveled at its lower portion, as shown at 45, said beveled portion constituting part of the bottom of the receptacle and the slot 36 extending thereinto. This beveled portion constitutes a support for the feed-regulating block 46, which is held in an inclined position thereby and has one end shaped so as to conform with the periphery of wheel 32. This block is engaged by the threaded end of a stein 47,

swiveled in a sleeve 4S, extending through the rear wall of the receptacle 27, and a head 49 is located on the upper end of stem 47, so as to render the same easy to rotate. This head is preferably provided with a series of openings 50 adjacent its periphery, any one of which may be engaged by the end of a .locking-spring 51, secured to the receptacle at one end. By means of the stem 47 the block 46 can be adjusted from or toward the wheel 32, so as to regulate the quantity of lubricant carried from the receptacle upon the periphery of said wheel. 4 A cover 52 is hinged at one end to the receptacle 27 and is adapted to be held in closed position by any suitable means. This cover has an inlet opening from which extends a yoke 53, adapted to be closed by a screw-cap 54.

In use the standard 3 is rigidly fastened upon a truck in such position that the feedwheel 32 will be close to the upper portion of but not above one of the wheels 2. The guides 9 are so disposed that when longitudinal movement is imparted to the recep-` tacle the wheel 32 will assume a position with the flange of wheel 2 within the groove 33. The upper end of the lever 16 projects into an opening 55, formed in thebed 56 of the car-body, and when the trucks are in their normal positions this lever willbe supported in a substantially upright position. The receptacle 27 is filled with a suitable lubricant, which will of course be kept from escaping therefrom by the clamping-plates 3S, the scraping-block 42, and the feed-regulating block 46. /Vhen the car travels forward on a straight track, the parts will be maintained in inoperative position with the wheel 32 out of contact with wheel 2. When, however, the car reaches a curve, the oarbody 56 will swing laterally in relation to the truck and will cause the lever 16 to swing upon its pivotal connection with the stem '11. As a result of this movement the cam-faces 17 and 13 will impart a backward movement to the operating-rod 19, and the bufferspring 26 will be tensioned to such an extent as to propel4 the receptacle 27 longitudinally on the guide-rods 9. The wheel 32 will thus be brought into contact with the wheel 2, and the flange of said wheel 2 will project into groove 33, as shown in Fig. 3. Said wheel 32 will be rotated by reason of its frictional contact with wheel 2 and will carry from the receptacle and into contact with the flange of wheel 2 all the lubricant adhering to its periphery. The thickness of this adhering lu bricant will of course be regulated by the block 46. By adjusting this block away from the wheel 32 a layer of lubricant which is of considerable thickness can be left upon the wheel 32, and by adjusting said block toward the wheel this layer can be diminished in thickness. The lubricant transferred to wheel 2 in this manner will be spread upon ICO IIO

sia-Lets the flange of said Wheel and carried thereby to the rail, thereby preventing the Wheelflange from chipping and at the same time obviating the scraping or grinding sound which is often produced by Wheels While traveling around curves. Of course one of these lubricators is to be provided at each side of the car, and although one may be used in connection with each Wheel it is only necessary to use one with each of the front Wheels of the car. The lubricant applied to these Wheels Will be sufficient to lubricate the rails and prevent injury to the Wheels follow- 1D0'.

tlt is to be understood that I do not limit myself to the construction herein described, as I am aware that modifications may be made therein Without departing from the spirit or sacrificing the advantages thereof, and l therefore reserve the right to make such changes as fairly fall Within the scope of the invention.
