DAVID F. ROBINSON, 0F LOS ANGELES, CALIFORNIA, ASSIGNOR 0F ONE-HALF TO I. 1V.[. HOLLINGSWORTH, OF LOS ANGELES, CALIFORNIA.

TRACK-OILING DEVICE.

Specification of Letters Patent.

Patented June 27, 1911.

To all whom it may concern:

Be it known that I, DAvrD F. ROBINSON, a citizen of the United States, residing in the city of Los Angeles, county of Los Angeles,

. State of California, have invented new and useful Improvements inV Track-Oiling Devices, of which the following is a specification.

My invention relates to an automatic oiling device for oiling the curves of railroad tracks, and is an improvement on the device patented byA me December 28th, 1909, by Patent No. 944,464, and the object thereof is to provide an automatic oiling device carried by the car, which will automatically and more effectually oil the curves as the car passes around the same than my former,

device.

A further object is to provide cleaning means for removing the dirt from the gutter between the guard rail and track rail in advance of the oiling device.

I accomplish this object by the mechanism described herein and illustrated in the accompanying drawings, in which,

Figure 1 is a front elevation of a part of a street car equipped with my improved devices. Fig. 2 is an enlarged side elevation of the parts of the oiling device shown at the right in Fig. 1, taken on a line near the parts under the car and looking outwardly. Fig. 3 is a section on the line 3 3 of Fig. 2, with parts removed for clearness of illustration. Fig. 4 is a central 'section of the swab wheel, the axle thereof being partly broken away. Fig. 5 is a side elevation of the swab wheel looking outwardly from the car.

In the drawings 10 is a bracket which is secured upon the bottom of the car 11.` On this bracket are pivotally mounted the

swab actuating arms

12 and 13. These arms preferably consist of bars of metal the outer ends of which are bifurcated which extend from the pivotal point outwardly about twelve inches beyond the car wheels 14 and 15 when the car is on a straight track. In Fig. 1 I have shown only the two front wheels of the car as the same appear when passing around the curve, with the main mountings of the car and other portions omitted for clearness of illustration. These swab actuating arms preferably consist of a bar of metal which extends through a yoke 16 secured upon thev top of the guide sheath 17 when the car is on a straight portion of the track as illustrated in Fig. 2. The outer ends of these bars are preferably bifurcated and the outer ends are held from spreading by a bolt 18. They are held in their eX- panded position by spring 19 which is coiled around bolt 18. Guide sheath 17 is rigidly secured to cross bar 20 which forms a part of the truck frame. In the sides of sheath 17 are slots 21 through which projects pipe 22, the outer end of which is closed by a cap 23 and the inner end of which is connected by hose 24 to reservoir 25. Within sheath 17 and longitudinally movable therethrough is the square pipe 26 which is closed at the top and is provided with bearings 27 in which a roller 2S is mounted. A roller 29 isV mounted in yoke 16 and the swab actuating arms pass between rollers 28 and 29. Pipe 22 passes through pipe 26 in liquid tight contact, and within pipe 26 pipe 22- is provided with a port 30 preferably in its lower side as best shown in Fig. 3. The lower end of pipe 26 is also closed and a round hollow pipe 31 passes through the lower end of pipe 26 and may be secured thereto by

nuts

32 and 33, or in any other suitable manner. On this pipe is revolubly mounted a swab wheel 34 which has a saucer shaped depression 35 in the iianged side of the wheel as best shown in Fig. 4. This saucer shaped depression is covered by the circular swab disk 36 which is of any suitable material, such as cloth or carpet. Swab 36 is held in place upon the swab wheel by a washer 37 and bolts 38 of which there may be any desired number. In Fig. 5 I have shown holes 332L in the wheel for three of these bolts as in practice I have found that number suliicient for the purpose. The edge of the washer is adjusted by means of these bolts to give the desired pressure upon the swab disk so as to permit the lubricant to flow out through the swab disk when oiling the curves as hereinafter explained.

The outer end of pipe 31 is closed and within the swab wheel said pipe is provided with a port 39 which permits of theescape of oil into depression 35. Between nut 32 and washer 37 a spring 40 is coiled around pipe 31, and between the swab wheel and nut 41 on the outer end of pipe 31 is a coiled t-he outer end of the handle 52.

spring 42 which is also mounted upon pipe 31. By means of springs 40 and 42 the swab wheel is normally held in a central position upon pipe 31. These springs allow the swab wheel to move longitudinally on pipe 3l so that the swab wheel automatically adjusts itself on curves of dierent radii. Pipe 31 is provided with a port 43 in that portion of the same which passes through pipe 26 so that the lubricant passes down through pipe 26 into pipe 31 through port 43 and out of pipe 31 into depression 35 through port 39, thereby coming into contact with the inner side of the swab disk, through which it flows and is spread upon the surface of the guard rail 44 when the curve is being oiled, as shown in Fig. 1. A lever 45 is pivoted in an arm 47 as best shown in Fig. 2. One end of this lever is bifurcated and the furcations straddle sheath 17 immediately below pipe 22. To the other end of the lever is secured a spring 48 which normally holds pipe 22 in its elevated position as shown in Fig. 2 and on the right in Fig. 1. The lower end of this spring is fastened to bearing 49 which bearing, as well as arm 47, is secured to cross bar 20. A pipe 50 leads out of the lower central portion of reservoir 25 and branches just below the cross bar and passes under said cross bar and thence downwardly to a point adjacent to the swab wheel where it is provided with a cutoff cock 51 having a handle 52 by means of which its plug is operated to open and close the cock as hereafter eX- plained.

Upon the lower end of each of the branches are pieces of hose 53 which have their lower ends open and lying in Contact with the swab disk on its outer side. Pipe 50 and its branches lead lubricating fluid from reservoir 25 and deliver it upon the outside of the swab disk as hereafter eX plained. On the outer end of pipe 31 is secured a cap 54 to which is secured a link bar 55 by means of a pin 56 which pivotally connects said link bar to said cap. The other end of link bar 55 is pivotally connected to IVhen the swab wheel is in its elevated position which is its normal position when the car is on the straight portion of the track, cutoff cock 51 is normally closed, but when the swab wheel is depressed as shown at the left in Fig. 1, and in dotted lines in Fig. 2 cutoff cock 51 is opened so as to permit lubricating fluid to flow to that swab wheel that is depressed. The depressing of the swab wheel also carries hose 24 downwardly at its outer end a suflicient distance to permit the lubricating fluid 57 in the reservoir to flow through the hose and into and down pipe 26 through pipe 31 and into the depression 35 in the side of the. swab wheel, whereby lubricating fluid is applied both internally and eX- ternally the swab whenever the wheel is depressed. In order to apply a very small quantity of lubricating fluid to the inner edge of the track rail 58, I provide one or more ports 59 which extend through the flange 34a as shown in Fig. 4. These ports `are filled with fibrous material 6() such as candle wicking or like material so that aV very small quantity of the lubricating fluid can be carried therethrough and applied to the track rail.

When the car is on the straight portion of the track the non-bifurcated portion of the

swab actuating arms

12 and 13 as shown in Fig. 2 will lie between rollers 28 and 29 and the swab wheel will be in its elevated position with cutoff cock 51 closed. Now as the car travels around the curve the front end of the car projects to the outside of the track as it travels around the curve. This carries the swab actuating arms to the posiltion shown in Fig. 1 with the bifurcated end of the inner arm drawn between rollers 28 and 29, thereby forcing pipe 26 downwardly against the tension of spring 48, thereby bringing the swab wheel upon the rail. Then the swab wheel is brought upon the rail the swab disk is brought into contact with the guard rail and distributes a graduated quantity of oil thereon so that when the flange of the wheel 15 contacts with the guard rail it moves thereon without the screeching sound produced by the ange of a wheel passing around an unoiled curve.

In order to remove dirt which accumulates in the groove between the guard rail and the track rail, I have provided a dirt plow 61, the point of which is adapted to pass into groove 62 between the track rail and the guard rail to the depth that the swab wheel travels so as to remove the dirt to that eX- tent from the groove. This plow is mounted upon pipe lbetween pipe 26 and nut 33, which last nut locks the plow against turning upon said pipe. The plow may be secured against turning upon said pipe in any other desired manner. I prefer to plug the outer ends of pipe 31 so as to make them solid except in that portion leading from port 48 to port 39.

As the reservoir and connecting mechanism are carried by the car truck and the swab operating arms are carried by the car body, the movement of the car body is utilized through the swab operating arms to force the swab wheel upon the track rail as the car passes around the curve, thereby bringing the swab disk into engagement with the guard rail, thereby oiling the same and preventing noise and reducing the friction between the car wheel and the guard rail.

It .will be observed that the connection between the reservoir and theinterior of the swab wheel is so arranged and proportioned that when the swab wheel is carried in vits normal elevated position, the lubricating fluid will not flow out of the reservoir. When the swab wheel is depressed, the lubricating fluid can flow down into the interior of the swab wheel, and also upon its exterior surface. It will also be observed that when the swab wheel is in its elevated position there is nothing to cause it to rotate, and that therefore there is no pressure to force the oil out of the swab disk, but when the swab disk is pressed against the guard rail and the swab wheel is revolved by its contact with the track rail, a pressure is exerted on the swab disk to squeeze the oil out of the same. The swab wheel is located as close to and in front of the advance wheel of the truck in the direction it is traveling as is permissible with the aforesaid movements of the swab wheel. By having reservoirs at each end of the car and swab wheels for each rail of the track at each end of the car, an efficient and economical device is provided for properly lubricating the curve of the track, no matter in which direction the car is traveling. It will be understood that the openings through pipe 26 and through pipe 50 are arranged to supply whatever amount ofoil is required to oil the curve, the size of the openings depending upon the liuidity of the oil, and the amount required for the purpose. It will also be observed that the dirt plow moves with the swab wheel and cleans out the groove just in advance of the swab. This plow is preferably made of spring metal so that in case any hard material gets wedged in the groove it will spring over theA same instead of bending or breaking.
