- spray nozzles adapted to be swung about an axis into and out of operative position with respect to-the rails; the'operationofthe valve in turn being controlled by a joint plate contactor also swingable toward andaway from q the rail and against which itfiiormally has a rolling engagement to energize and deenergize the valve in the [passing of each rail Joint.

The primary ob ect of the lIlVGIltlOIl is to provide an improved mechanism for simultaneously moving bothjthe nozzle and contactor into andout oti operat'ive position with respect to the rail. j V, 7

Another object of the invention istoiprovide an improved mounting for thecontacto'ii whereby that portion of the contactorhaving a rolling engagement upon the maybe accurately and easily adjusted for rails of different heights.

A further object of the invention is to proviee an improved mounting of the nozzles on the valve casing whereby the'angular position of the nozzle when in operative position may be determined to regulate the area i contact of the spray upon the rail joints.

Still another object of the invention is to provide improved mounting of'the valve upon the vehicleso that it may be adjusted laterally to bring its axis into the plane of the rail and at the same time evenly space the nozzles on each side of the rail.

"These objects of the invention as well as the many advantages thereof. will more fully appear as I proceed with my specification. In the drawings: Fig. 1 is a view in side elevation of a rail joint oiler embodying my invention.

j Figuretis a diagrammatic view-showing the electrical circuit between the "electromagnetic "valve and associated eontaetor and which will be more fully described latei'.

Referring nowin detail to that 'einbodi ment of the invention illustrated in the accompanying drawings, 1 indicates use. whole the frame of a rail joint oiler mounted "on front rear axles Q'and 3 respeetive'1y,;eah of which is proyided with a pair "of wheels 4-4 to run on the rails 5 arai1readtraek. The rai l'lengths in each-rail ofthetr'acks are connected together by inner and 'outerj'oint platesand bolts 6 in the "manner well known.

The wheeled frame thus genemu desc ib d' forms theve'hicle of rail joint oiler which is preferably 'seli-prgm'elled having a suit able power plant operatively connected to the rear axle but not herein shown. The frame ofthe vehicle is rectangular in plan and embodies side sills? and transverse end sills 8- 8 the side sills being duplex in their nature and each comprising a'pair oi laterally spaced 'edgewise' disposed inner and outer channels 7 a and 7b respectively, with" th' ilan'ges thereof facing toward each-ether as best shown in Figs. 3 and 5;

l is threaded a locking nut 15.

Fixed to and projecting laterally from each side sill is a plurality of brackets 9 upon which is supported a casing or tank 10 adapt ed to contain the fluid to be sprayed, preferably a low-grade, slow evaporating oil.

11 indicates as awhole the casing of an electro-magnetic valve mounted upon and projecting laterally from the outer side sill members 7 Z) at a point midway between the axles. Saidcasing includes an upright back flange 12 secured to the web of the sill member 7 b by means of bolts and nuts 13, one near each end of the back flange. Carried by each end of the back flange, vertically above and below each attaching bolt and nut 13 are set screws 14:, each of" which are threaded through the flange to engage the web of the sill member 7a. On each set screw By manipulating the set screws and nuts 14 and 15 after loosening the bolts and nuts 13,"the casing may be shifted laterally toward or away from the said sill member to accurately position the vertical axis of the valve casing in the vertical plane of the rail 5. After this adjustment has been made, the set screws and bolts are tightened up as well as the bolts and nuts 13 whereby the valve casing is secured in the desired position. Thus inaccuracies in the variousparts may be readily compensated for.

The valve casing comprises an open bottom casing member 16 and an open top casing member 17 both of which have coacting radial flanges. Interposed between said flanges is an annular. plate '18, and said flanges and plate are all secured'together by suitable bolts19 only one of which appears in Fig. 3. Said plate which has a centrally disposed apertured flange 18a therein divides the casing as a Whole into top and bottom chambers 20'. and 21 respectively, the former being a magnetic coil chamber and the latter being a pressure fluid chamber. Fluid under. pressure is admitted to said last mentioned chamber, by means of a conduit 22 leading from a pressure generating means supplied with fluid from the tank 10. As

' the pressure generating means forms no particular part of the present invention it is referredto only generally and is not herein illustrated. In the casing member 17 and surrounding the chamber 21 therein is an annular heating chamber 23 into which the exhaust gases of the power plant for propelling the vehicle is conducted by a pipe 24 opening into said chamber at the rear above the pipe 22. Said chamber opens at the front to the atmosphere for the discharge of said exhaust gases which act to heat up the fluid in the chamber 21 and thus increase its fluidity.

Depending from the bottom of the casing member 17 is a boss 25 having a taper-bottomed recess 26 therein which opens into the chamber 21' and extending transversely through said boss below said recess is a horizontal passageway 27 connected to said recess by an axially disposed port 28. In the chamber 20 is located an annular magnetic coil 29 resting at its bottom upon the plate 18 and suitably insulated from both said casing member and plate. 30 indicates the normally fixed but adjustable core of the electro-magnetic valve as a whole which is threaded through the top wall of the casing member 16 to extend a suitable distance down into the interior of said annular coil. 31 indicates the movable core of the valve which is guided in its movement by the apertured flange 18a of the plate 18. Said core is in the form of acylinder of magnetic material and threaded axially into the bottom end thereof is the top end of a stem 32. To the bottom end of said stem is fixed a block 33 in which is carried a valve member 34 in the form of a steel ball adapted to seat on the tapered bottom of the recess 26 about the port 28 to control the passage of the fluid from the chamber 21 to the lateral passageway 27. When the coil 29 is energized, it attracts the core 31 to lift the ball valve off the seat so that fluid under pressure enters to the passageway 27 and when said coil is de-energized, the core 31 descends and the ball valve seats itself and closes off the flow of fluid to said passageway.

Associated with said valve as a whole is a duplex spray nozzle head 35 comprising laterally spaced branch pipes 3636 connected at a point between their ends by a transverse pipe 37 and a transverse bar 38 below the same. The pipe 37 equalizes the pressure in the branch pipes while the'purpose of the bar 38 will later appear. To the top end of each branch pipe is secured a swing joint elbow fitting 39 the nipples 4040 of which are threaded into the ends of the transverse passage 27 This connection is such that it permits the nozzle head as a whole to be swung about an axis coincident with that of said passageway 27. The bottom end of each branch pipe 36 is bent outwardly and each end has a nozzle opening 41 facing the rail and associated with each opening is a valve stem 42. The valve stem and nozzle opening are so disposed that when the nozzle head is in its operative position with respect to a rail a conical spray of the fluid under pressure is delivered upon the joint plates of the track only and not upon the tread surface of the head of the rail, as is apparent from an inspection of Fig. 3.

Means are provided to manually swing the nozzle head about its connection with the boss 25 and such means are as follows: Secured to the outer sill member 7?) are front and rear pairs of brackets 43 l4, each bracket being of the same construction. Each bracket includes an upright plate 15 fixed to the outer face of the sill member 7?) and a V .liorizontally. disposed arm 46 suitably webbed to said plate for strength. Said arm is .of such .a length that :its .outer and projects a suitable -.distance outwardly beyond the :sill member 77) whilezi-ts innerrend-extendsa less distance inwardly beyond thesil-l 1nemher'7b. 1n :the outcr end of each arm is ;a'-longitudinally extending hole 47' and depending from said outer endis aneard-S in-whichisatransverse hole 49. The innerend of said arm has top and bottom ear-s 50.5Ti respectively and in-the ear 51=is a 'holef52-in line witlrthe hole 49 in the car 48. In said holes 49 and '52 .is journalled a transverse :rock shaft 53. The top ear'50 of said bracket has a hole 54 therein in whichis fixed a-stub shaft 55 arranged vertically .abovethe shaft 53. Gn theinner end of the shaft 53 is'fixed a pinion 56 which meshes witha segmental gear57journalled on the stub shaft 55. Saidsegmentalgear is provided with a hand lever 58 for manual operation and on the sill member 7]) is a notched quadrant 59 to eoact with a latch or.

detentGO on the lever (see Fig. 2) whereby tion. Onthe shaft 53 is a sprocket 61 fixed thereto by a set screw 62the sprocket being arranged on said shaft in the plane of. the rail 5. a A sprocket chain 63.is fixed at its top endto said sprocket and'at its bottom end-to the cross bar-38 of the nozzle head. ;On the front side'of the boss is mounted a depending'braclret 25aandsecured to the front end of said bnacketand to said nozzle head cross bar 38 is a pair of contractile springs a which normally urge the nozzle headinto its operative position. Threaded through said bracket between said springs :is a longitudinally extendingsetscrew 25?) adapted to'be engagedby the cross pipe 37 of the nozzle head under the action of the springs 35a. By

screwing said set screw-in'or out the angularity of the nozzle head when in its operative position may be determined, said set screw acting as i an adjustable stop shoulder therefor. lhis feature is important because by it, the angularity of said nozzle head'may be determ ined to properly gauge the position of the nozzle openings with respect. to rails of different heights. It apparent that when the lever 58 ismoved rearwardly the sprocket .61 and shaft 53 are rocked counter clockwise towind up the chainand thus lift the nozzle head 35into its inoperative position wi-threspect to the rail against the action of the springs 35a, the detentGO-entering theproper notch in .the quadrant to hold said nozzle .headin this position ashest shown in Fig. 2.

Ltheengagement ofthe cross pipe237 with the screw 25?). It. is'po'inted. out-atthistimethat by floosening. the set screw '62 which fixes :the sprocket 61 l on the shaft 532theangular relation =between the sprocket :61 and the rock shaftf53wmay be changed by turning the sprocket; on :the shaft and thenlocking it to thershaftbythe set serewl62. :Thus the posi-v tion ofthe-actu-atinglever need in no manner be -changed with respectto the angularity of 1 the nozzle head and this feature is advantaare provided, for automatically making andbreaking the circuit to the electromagnetic valve each tune a rail JOII'lll-lS- ap- I proaohe'd and passed whereby the passage of fluid underpressureto the nozzle headis eontrolledand such means isas follows: In

theholes rain hemed ends of the arms'afi of the-front pair of brackets 43 is journalled. a

rock shaft 65 suitably heldin said arm ends against endwise movement. -Capable ofbe ing securely fixed to said shaft is bifurcated plate .66 which includes a sleeve 67 embracing apart-of said shaftand adapted to be locked thereto byia set screw 68, and two spaced plate-likeparts 69- 69 each having a pair angle to said sleeve. Interposed betw-eensaid plate lile'parts"69.69 is one endof a flat plate-i like arm 7-1, bolts '72 with sui table I nuts thereon passing throughsthe slots 7 O70 and through suitable holes in said end of the plate like arms. The-ether endof-said arm carries a I right 7 angle. flange 73 and j ournalledon. an

diagram in Fig; 7 and in said figure, one

side of. a generator 81 and battery 82 are grounded while theother sides thereofare connected bya conductor 83 in which is interposed an alnm-eter '84. ,One'terminal of each .coi129 is connectedbya conductor 85 to an associated fixed contact 73 while tlieuother terminals of said coils are connected by a eonductor-86'and'asuitable switch 87 isinterposed between said conductors :83 and 186. When said roller 74 engages the. railas before mentioned, said ifinge-r projects below the head of the rail and intoa position to engage the inner-j oint plate. "Thus-when a Itlllj oint is'approachedthefinger engages the advancingend of theinner plateand is actuated therebyito-close the switch-and likewise close the circuit to the electro-magneticvalve'which operates %to energize isaid coil a as before deserlbed. As the joint is passedthe vfinger 75 slips off-the trailing end of said plate to open ltheswitci h breaking the circuit to the coil and dB- nergizing the same. Should .a groove 1 9e of slots/70 70 therein extending ata right wear in the periphery of the wheel which would change the relative positionof the contact or finger75 or should a section of track be encountered wherein the rails are smaller in cross section and the position of said finger need therefore be readjusted, it is only necessary to loosen the bolts 72 of the member 66 and lengthen or shorten the} arm 7 5. By either lengthening or shortening the arm 75 a new area of the roller is brought into engagement with the rail or the relative desired position of the contact linger may be readily brought about. Of course, after making this adjustment the bolts 72 are again tightened up. 'By loosening the set screw/'68 andmoving the member 66 one way or the other on the shaft, the timing of'the making and breaking of the circuit to the valve WVltllIQTGIQIlCQ to when it opens and closes maybe determined whereby the length of spraying on each joint maybe governed. Thus where some railroads desire to spray threeinches behind and three inches in front of'each o-int, this may be provided for and when it is desired that the spray be applied to theljoint plates only and not behind or in front of the same this .too, may be provided for.

Means are provided for swinging the contactor arm about the shaft 65 as an axis and preferably the same is operatively connected up with the lever 58 so that when the nozzles are swunginto their inoperative position the contactor is likewise swung into its inoperative position away from "the rail as best shown in Fig. 2. To this end I provide the following. In the hole 54 of the top arm o-f'the bracket 43 just forward of the electromagnetic valve is fixed a stub shaft 76 carrying a grooved segment 77. Secured to one end of said segment is one endof a chain 7 8 which extends around the groove of the segment and is then attached at its other end to a web 79 on the rear side of the contactor arm 71 as best shown in Fig. 6. Bythis arrangement of chain and segment, leverage onthe chain is always the same as the tangent of the segment remains constant. It is preferably desirable to connect the segment to the lever 58 so that it may be swung into inoperative position simultaneously with the nozzle head 35. To this end I find it convenientto interpose a link 80 between the lever 58 and segment 7 7 as best shown in Fig. 2. In this manner upon actuating the lever 58 the nozzle head 35 and contactor arm 71 may be simultaneously swung upwardly into inoperative position and held therein by the detent 60. When the detent is released the springs 35a act to return said parts to their operativeposition with respect to the rail as before described.

As before mentioned, the brackets of both pairs of brackets 43 and 44 are all alike and from an inspection of Fig. 1 it appears as if the rearmpst bracket of the pair 44 has no function. It is pointed out that on some railro'ads'there is no provision for turning such an oiler around so that it may run forwardly upon the other track when the end of the road has been reached. To run the oiler backward is possible but not only would the nozzle be facing in the wrong direction but the contactor would be to the rear of the nozzle so that the oiler could not operate as intended. Under such conditions, the bracket 25a would be removed from the front side of the boss 25 and-replaced upon the opposite side of the same and then hooked up with the nozzle head. The shaft would be removed from the pair of brackets 43 and replaced in the brackets 44 and the shaft 53 would likewise be removed from the arms 48 and 51 of one bracket 44 and replaced in the same position inthat bracket 43 adjacent the magnetic valve. The contactor on one side of the machine would be changed for that on the other side so that'the contactor finger 7 5 would face in the properdirection. The lever 58 and segment 77 would then be removed and replaced in reversed position. Thus when the oiler is travelling upon the second track of the railroad, with the rear end of the oiler foremost, the positions of the various operative parts relative to the direction of travel of the oiler as a whole will be the same as before. This change in the relative position of the parts may be readily made so that even though no turntable is found at the end of a run,the oiler may be used upon another track and ran rearwardly thereon. Thus a great dal of time and inconvenience is saved when such a condition is met with.

My improved rail joint oiler is ositive in operation, and is readily adjustab e to meet all contingencies. It comprises but a few parts which are strong and rigid and which are not only easily assembled but are readily accessible for inspection or repair.
