Description

Jam M9 E93@ M. D. BOWEN A g@ I kROADWAY MACHINE Filed April 1954 Patented Jan. 14, 1936 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to railway maintenanceof-way equipment and has for its principal object to provide simple and economical apparatus for oiling the sh joints or rail joints that will travel along the rails and deliver a blast of oilbearing air, and that can be readily rolled laterally ofi the track to let a train pass, and back again afterwards, without being disorganized.

Further objects and advantages or the invention will become apparent as the description is read in connection with the accompanying drawing, in which Fig. 1 is a perspective view showing one embodiment of the invention on a section of railway track;

Fig. 2 is a longitudinal vertical section through the air and oil tank and one end oi the carriage;

Fig. 3 is a transverse section taken on the line 3 3 of Fig. 2, and

Fig. 4 is a somewhat diagrammatic end View showing the device in solid lines on the track and in dotted lines rolled to one side thereof.

But this drawing and the corresponding description are used for the purpose of disclosure only, and are not intended to impose limitations on the claims.

The main frame of the carriage includes three tubular hoops IEB, il and l2, connected by three tubular side pieces I3, i4 and I5, and two angular side pieces i6 and Il, all welded to the peripheries of the three hoops.

The side pieces I6 and Il take the place of sleepers for the carriage and are equipped with aligned flanged Wheels i8, journaled in boxes l, welded to the sleepers.

A socket piece 2i] welded to the top of the angle pieces i6 and ll', receives one end of a guide bar 2l, the other end of which is equipped With a roller 22 for engagement with the rail 23 opposite to that on which the wheels i8 run.

Each of the end hoops lll and i2, is welded to the outer ends of tubular spokes 24, the inner ends of which are welded into hub structures comprising perforated plates 25 and tubes 2B, all welded together. After the welding the tubes 26 are bored out and nished, or hushed, to receive trunnions 27 and 28, welded to channels 29, which, together with side angles 39, form hang- 0 ers for a rectangular apparatus -bed composed of side channels 3l and end channels 32, all welded together to form one integral piece.

Assembled on the apparatus bed 3l, from left to right, in Fig. 1, is a gasoline engine 33, connected by a V-belt drive 34 with an air compressor 35, in turn connected by a coil tube 36 to a tank 31.

By arranging the apparatus in this wise, the shafts 3B and 39 of the engine and the air compressor are placed crosswise to the apparatus bed and both the starting crank lill and the belt drive 34 are made easily accessible.

The tubing 36 is connected toa pipe 4 I, (Fig. 2) extending through and Welded to the heads 42 and 43 of the tank, and provided with perforations 44 distributed substantially throughout that portion of its length exposed to the interior of the tank.

A full charge of oil should have a level in the neighborhood of that indicated at 45, hence the air from the compressor will be delivered well below the surface of the oil and so directed as to cause circulation adapted to keep all solid matter in suspension and prevent any obstructing accumulation in the bottom of the tank.

The compressor shown has air cooling fins 4S, but no other cooling is used, to the end that the entering compressed air may be hot enough to warm up the oil and make it highly iluid.

A hose nipple 4l (Fig. 2) extends through the hollow trunnion 28 and is connected with a suitable length of hose 48, tted with a nozzle 49 having iiattened discharge 5i) adapted to deliver a mixture of compressed air and entrained oil into the cracks between the iish plates or angle bars 5l and the rails 23.

Oil is taken from adjacent to the bottom of the tank through a nipple 52, welded in the head 43, and connected by an elbow 53 with an upright pipe 54, leading to a T 55 into which the hose nipple 4l is screwed.

Air is taken from the upper side of the tank through a nipple 56 welded to the tank and connected by piping 5l with an atomizer nozzle 58 comprising a tube welded to a bushing 59 threaded into the T 55.

The atomizer nozzle used in this particular embodiment is 1/2 X 6, the bushing 5S is a standard 3A. x 1%, and the T 55 is a standard 11/4" x 11/1 X en. These dimensions will suiciently indicate the sizes required for success.

The flow of air and oil is controlled primarily, and their relative proportions regulated by gate valves l and 6l, respectively. The deliversr through the nozzle 49 is controlled by a quick r operating valve 62 of the Lunkenheimer grip lever type, connected between the nozzle 49 and a hose nipple 63, which latter forms a handle to be enclosed in the operators hand with the grip lever 64 of the valve 62.

The main frame of the carriage is 30 in diameter and 72 long, the engine illustrated is a 3 bore x 31A stroke, 4 cycle single cylinder L head, air cooled, gasoline motor having a Speed range of approximately 1800 to 2600 R. P. M. and known to the trade as Briggs & Stratton Model Z.

The air compressor is a single cylinder 3% x 31/2", known to the trade as a Curtis No. 50.

The apparatus as a whole is comparatively light, and can be pushed along easily by one man, who also watches for coming trains and can quickly throw the machine from the solid to the dotted line position in Fig. 4, and back again. Another man handles the nozzle and adjusts the air and oil.

The quick operating valve enables him to start and stop the flow by simple movement of his ngers in gripping and releasing the lever 64. In starting, of course, he will hold the valve 62 open and adjust the valves 69 and 6| until the proportions of air and oil are right, after which the ow is entirely controlled by squeezing and releasing the grip lever.

One particular advantage of this equipment is that it permits the oil to be put behind the angle bars or iish plates directly at the surfaces to be lubricated. The attened nozzle causes the stream to be delivered in a thin blade or sheet, best suited to enter the joint without Waste.

The air pipe 4| is shown in Fig. 2 a considerable distance above the bottom of the tank and the nipple 52 is shown above it. This is merely for convenience in illustration. Actually the pipe 4| is only about half an inch from the bottom of the cylindrical tank, and the nipple 52 is alongside it about the same level.

The oil used for this purpose contains various foreign matter including solids, tars, waxes, etc., land when the apparatus is not in use there is a tendency for this material to settle in and clog the pipe 4|. To facilitate cleaning the right end is tted with a plug 65 and the left end with a. union 66. When these are removed a rod or other cleaning device may be run through the entire length of the pipe.
