TRACK-SPR-AYING APPARATUS.

Specification of Letters Patent. Patented June 13 1922 Application filed March 10, 1920. Serial No. 364,842.

To all whom it may concern:

Be it known that JOHN NIoHoLsoN, formerly a citizen of the United States, and a resident of Houston, county of Harris, and State of Texas, did prior to his decease in rent certain new and useful Improvements in Track-Spraying iipparatus, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof. v

This invention relates to apparatus for treating railways and has special reference to apparatus of the general Cl'ldlilC'tlGI' shown and described in Patent No. 1,169,990 granted February 1, 1916 to Andrew J. Neafie.

One object of this invention is to improve the control and simplify the regulation and adjustment of track spraying apparatus of the aforesaid character.

\Vhen track spraying mechanisms as hitherto constructed approached a crossing or other irregularity requiring temporary elevation or adjustment of the parts of the track spraying device, several hand levers were necessarily adjusted in order to shutoff the supply of the liquid with which the track was being sprayed, to shut-off the air supply used to force the liquid through the nozzle, and to elevate the track spraying parts, etc.

According to this invention independent means is provided for adjusting the flow of the oil or other spraying liquid and the air so that the force of the spray discharged from the spraying nozzles is susceptible of close adjustment. However, the necessity of throwing these means out of adjustment is avoided and the operation of adjusting the sprayer in going over a frog or crossing is simplified by providing a single means. responsive to a hand lever or the-like, for quickly and easily accomplishing not only the elevation of the track spraying nozzles but also the shutting off of the supply of oil and air to the nozzles. The same means is adapted to lower the spraying apparatus and reopen the oil and air supply pipes.

Other advantages and objects of this invention will be set forth hereinafter and the appended claims set forth the features of novelty.

Referring to the drawings:

Figure 1 is a side elevation of the opera tion of a car equipped with a track spraying device which constitutes an embodiment of justing the position of the val Figure 7 is a view corresponding to Figure (5 of the oil control valve and mechanism.

10 designates a car which is intended to be representative of any suitable railway vehicle which may be equipped with the rail spraying apparatus and control mechanism of this invention. The spraying mechanism comprises a frame 11 which may, for eX- ample, be formed of piping and is composed of a transverse tubular support 12 at the bottom, a pair of vertical side supports 13 and 141. a tubular crossbar 15 at the top and a connecting rod 16 attached to the crossbar and joined at its upper end to the piston 17 of an actuating cylinder 18.

20 designates a source of compressed air which may be maintained by any suitable air pump which forms a part of the train equipment and is not shown in the drawing. Leading from the tank 20 is a pipe 21 having a small branch 22 which supplies air to either end of the cylinder 18 in response to a control valve 23 actuated by a regulating 'handle 24.

The arrangement of parts is such that upon movlng the handle lever 24 in the one direction or the other the piston Within the cylinder is actuated to elevate or lower the frame 11 and the attached parts which will now be described.

Referring particularly to Figures 3, 4; and 5. 25 designates the track spraying'nozzles which are arranged in pairs each pair being in position to spray one of the rails of the track. The arrangement of nozzles for the two rails'is identical and it will be necessary to describe only the one set in detail.

Extending; downwardly from each end of the transverse supporting pipe 12 and connected thereto, is a comparatively short pipe section 26 which supports and is connected to a yoke 27 having a central T 28, short lateral sections and downwardly extending inclined sections 29.

One of the nozzles 25 is pivotally mounted at the lower end of each of the inclined sections 29 and is yieldingly held in position by a helical. spring 30 which surrounds the inclined section 29 and is atfixed at its upper end. to a pin 31 on the pipe bracket 27 and at its lower end to a pin 32 on the nozzle 25. The parts are arranged in such manner that the pipe 1.2 constitutes a conduit through which. oil is supplied to the nozzle as well as a support for the nozzles, the oil being supplied to the pipe 12 through a flexible hose or pipe connection 33 as clearly shown in Figures 1 and 2.

The air is supplied to nozzles 25, through flexible hose 34 connected at their inner ends to an air pipe 35 which extends transversely of the car and is supported by straps 36. It has downwardly extending projections 37 terminating in T connections from which lateral branches 39 extend. the hose connections 34 being coupled to the branches 39.

The air supply pipe is designated 40 and is connected to the supply pipe 21 at its upper end and. to the pipe 35 at its lower end. The valve 41. controls the introduction of air to the pipe and the nozzles. The valve 41 is provided with an actuating lever 42 which is coupled by a link or rod 43 to a bell crank and handle lever 44 pivotally mounted at 4:5. The pipe branches 26 in the oil supply and supporting lines are provided withvalves 46 which are adapted to be concurrently actuated by the rotation of a transverse rod 47 which is accomplished by the bell crank and control lever 419 which is coupled to an arm 50 on the rod t? by a link or rod 51.

In addition to the air control valve 41 there are a pair of air control valves 52 in the air pipe branches 37. These valves are intercoruiected by a rod 53 having an actuating arm 54 which is joined to a projection on the frame 11 by means of a link 56, the arrangement oi. parts being such that the upward and downward movement of the frame causes the closing and openingof the valves 52. The up and down movement'o't the framealso effects the closing and opening of the'oil control valve 46.

A pair of guard plates 57 are hingedly connected at 58 to a substantially horizontal.

plate 59 spaced slightly above the tread oi the rail. Plate 59 is supported by a strap or bracket 60, as shown in Figures 1 and 2.

Feeh. of the plates 57 has a lateral pro jectlon 6lw1th a lug G2 at the top connected. by links 63 to a pin fi ton the T connection 3280f the nozzlcsupport. Each of the links 63 has an elongated slot where it engages the pin 6 to permit the tree upward swinging movement of each guard plate on its hinge.

Furthermore when the nozzles are elevated the pull on the links serves to swing the guard plates upwardly so that they are elevated substantially into the plane of the support plate on which they are mounted.

The operation of the apparatus will now be described:

Assuming that the parts occupy the positions in which they are shown in Figures l.. 3 and 4- it will be observed that the spray nozzles 25 are directed so as to discharge oil in linclv divided form against the side and web surit'aces of the rail while at the same time guard plates 57 prevent the oil f om being supplied to the tread surface of the rail where oil is. of course. not only unnecessary but very undesirable. The mixture of oil and air may be adjusted by varying the positions oil the levers 44: and 49 which govern the openings of the valves 41 and 4:6.

it one of the nozzles accidentally meets an obstruction it will merely be swung about its pivotal mountingon the pipe section 29 in opposition to the spring 30 and would return to its normal position as soon as the obstruction is passed.

The parts are arranged, however, in such manner as to enable the nozzles, guards, etc. to be elevated to clear the track entirely whenever it is desired to pass a frog, crossing, or the like. by merely shifting the position of the lever 2! to actuate the valve 2?) and admit air to the lower end of the cylinder '18. When this is done the frame 1.! is elevated and lifts the pipe 12 together with the projections 26 and the nozzles 25.

\Vhen these parts move upwardly into the position shown in Figure 2 the valves to are automatically shut off because the valve rod remains in a fixed position while the pipes in which the valves 45 are located are raised. the clmnge in the relation of the parts being clearly illustrated in Figures 1 and. 2. At the same time the air controlled valves 52 are adjusted since the lever arms 04 are connected, as already explained, to the lugs on the movable frame.

In other words, the arrangement of-parts is such that when the single lever 24 is suitably adjusted the frame 11 is elevated carry ing the nozzles upward and automatically shutting off both the air and'oil from the nozzles. After the crossing or the like is passed the lever 24. is again adjusted to admit air to the top of the cylinder 18, thus forcing the frame 11 downward and returning the parts to their original positions and turning on the oil and air to the nozzles This is accomplished This arrangement has a number of marked advantages some of which may be enumerated as follows:

A single control lever cares for the necessary adjustment of parts in passing a crossover or the like T e elevation and return of the nozzles is effected without the necessity of readjusting the relative oil and air openings which are independently controlled by the levers 44 and 49.

The guard plates 57 are swung from the positionshown in Figure 4 to a substantially horizontal position by the elevation of the frame 11 since they are connected by the links 63 to the T 28 which forms a part of the frame.

Various other advantages will be apparent to any one skilled in the art to which this invention pertains.

Apparatus of preferred form and construction has been illustrated and described for the purpose of showing a way in which this invention may be used, but the inventive thought upon which this application is based, is broader than this illustrative embodiment thereof, and therefore no limitations are intended other than those imposed by the appended claims.
