12 Claims.

My invention relates to apparatus for applying lubricant to the flanges of the wheels of railway rolling stock and thence to the rails on which they run, to reduce the wear of the flanges and rails and to afford easier traction; such apparatus being especially useful on curved tracks, wherein the friction and wear are especially severe at the outer rail of the curve. My present invention is particularly an improvement upon my invention set forth and claimed in my p-rior patent, No. 1,831,313, issued November 10, 1931.

Broadly, the object of my present invention is the same as that of my previous invention just referred to, in that I provide for guiding the wheel during its travel along an extent of rail wherein lubricant is to be applied, in such manner that the wheel flange is spaced an ample distance from the inner side of the rail to permit suitable lubricant-emitting means to be disposed in the best manner for applying the lubricant to the wheel flange, without exposing said means to wear or injury by the flange.

As distinguished from that prior invention, my object is to simplify the construction of such a device and to make it more reliable in operation; especially in respect of insuring that the means which determines the path of travel of the wheel shall be maintained in proper relation to the track rail on which the wheel travels and from which the flange is to be spaced as above mentioned.

Other objects will appear in the course of the following description, illustrated by the accompanying drawings, in which- Figure 1 is a plan view of one rail of a track, and parts of the cross ties thereof, showing a preferred example of my invention applied thereto, and also showing a car wheel in operative relation to the invention;

Fig. 8 is a partial plan View of this modification.

In my prior patent I fully disclose and claim a lubricant reservoir with means for conducting lubricant therefrom up to the track rail. "The reservoir is embedded below the top plane of the track bed and is provided with mechanism which is actuated by pressure of the wheel flange to force the lubricant up to the rail and wheel as the wheel passes the device.

As such a reservoir and the portions of the I conduit and mechanism thereof below the top of the track bed are suited for the supply of the lubricant in the present invention, it seems sufficient to illustrate like reservoirs only diagrammatically herein, as dotted circles, in Figs. 1 and 4, and to show only the upper portions of the conduits 2 leading up from the reservoirs I, as well as of the rods 3 for operating the reservoir mechanism of the character above mentioned with reference tosaid prior patent. Said patent also discloses and claims means for pumping air into the reservoir to facilitate the discharge of lubricant therefrom, which means is operated by means of an element depressed by the passing wheel flange; and such an element is represented as a rod d for each reservoir, only the upper parts of these being shown in Figs. 2, 5 and '7. Such pneumatic means, it will be understood, is not essential; and any one of lubricant supplying or forcing devices other than that of said prior patent may be adapted for supplying lubricant in the present invention.

My prior patent mentioned sets forth a devic in which, to guide the lubricant-receiving wheel for spacing its flange from the lubricant-receiving rail to admit the lubricant-emitting means Without wear or damage from the wheel flange,

a guide or guard rail is mounted adjacent to the opposite rail of the track and is engaged by the inner side of the wheel. The two wheels being rigidly connected by their axle, as a unit, this oppositely located guard rail will pull the pair of Wheels axially away from the side of the track where the lubricant is to be applied; it being understood that the distance between the inner faces of the rails, or gauge, is always somewhat greater than the distance between the outer faces of the flanges of a pair of wheels. Thus the pair of wheels have some freedom of movement axially at all times. On curves it is the practice to increase the gauge of the rails over that on straight track. The lubricant is applied to the rail in the tangent approach to the curve, and it is feasible to similarly increase the gauge of the rails in the approach. Such pulling of the pair of wheels away from the lubricantreceiving side of the track therefore permits a practicable lubricant-discharge means to be used, out of contact with the passing wheel flanges, if the proper relation of the oppositely located guard rail to the lubricant-receiving rail is maintained.

This maintenance, however, depends upon the security of fastening of the guard rail to the track rail opposite the lubricant-receiving rail; usually by bolts that stretch and loosen under the impacts of side thrust of the guided wheels. Also, as the relation between the two rails at the opposite sides of the track is dependent upon their fastenings to the cross ties, usually of wood with the rails secured thereto by spikes, accurate installation for the required accurate guidance of the wheels is difiicult, and if made sufficiently accurate may not be maintained so by the crosstie connection.

My present invention provides for elimination of such inaccuracy, and for maintaining the accuracy, by confining the wheel-guiding structure entirely to the rail that is to be lubricated. This is accomplished by providing a wheel guiding element at the outer side of the rail that is to be lubricated. Also, preferably, a second guiding element is provided along the inner side of the rail. In any case there is no necessity of applying any thing to the opposite track rail; and preferably the connection to the rail at the lubricating side is so made that there is no use of bolts or the like for such connection, which are liable togagement with the track rail that the guide struc ture is practically unitary with the track rail and will not be materially displaced with relation thereto under the axial side thrusts of the wheels in either direction. Further, the structure is adapted for shop production, ready for track in-' stallation, as distinguished from assembly in the track, as is required in my previous invention above referred to. This has the added advantage of convenience for those who must install the devices on the tracks.

I have shown in Figs. 1, 2, 3, 5 and 6 a construction in which the guide elements and their connecting means are made integral, in longitudinally succeeding sections; the short device in Fig. 4 also being integral, but a single section only. In Figs. 7 and 8, instead of an integral casting, rails, which may be such rails as have been discarded as unfit for use as track rails, are used for the guide elements, and brackets that engage the rail of the track are rigidly secured to the guide rails, preferably by welding. It will be understood that the construction in this example may be sectional, after the manner of the construction shown in Figs. 1, 2, 3, 5 and 6.

In the preferred construction, Figs. 1, 2, 3, 5 and 6, the device is shown in three sections; the middle section 5 being straight and the end sections 5a and 5b having diverged ends on the guide elements to receive and guide the wheels into the space between the guide elements, after the manner of guard rails well known in the art.

Transverse upright webs join the two opposite guide elements together, in each section 5, 5a or 5b, extending under the track rail and being fixed to the base thereof. Thus, in middle sec tion 5, three such ribs or webs 6 connect the outer guide element I with the inner guide ele ment 8; their transverse portions extending under the track rail 9 and engaging the bottom of the base I0 thereof. Lugs II and I2 project inward from the inner sides of the guide elements I and 8, respectively, engaging over the adjacent edge portions of the base Ill; these lugs being in the transverse vertical plane of the webs 6, and the lug I2 being continuous with the adjacent part of said web 6, in each instance. The two guide elements I and 8 and the webs 6 and lugs II and I2 are preferably parts of one integral casting; as also are feet I3 fitting on the tops of the respective cross ties I4 of the track, and flanges I5 and I6, respectively, on the ends of the guide elements 1 and 8, at one end of the section, and extending laterally outward from the respective elements. At the opposite end of the section, one of the webs 6 has its face coincident with the ends of the elements I and 8, corresponding with the flanges I5 and I6 of the first mentioned end of the section.

The section 5a, seen at the right in Figs. 1 and 2, has two transverse webs connecting its outer guide element 'Ia and inner guide element 3a; the left hand web 6a corresponding to the webs 6 of the middle section 5 in every way, and the second web Ba, near the right hand end of the section 5a differing from the others only in being wider in accordance with the divergence of the end portions Ia and 8a of the guide elements, as before alluded to, and in having its tie engaging feet I3a at the left instead of at the right of the web. The left hand ends of the elements Ia and 8a have the flanges I5a and Ifia, like the flanges I5 and I6 on the adjacent end of the middle section 5.

The section 51) forming the left end part of the device, as seen in Figs. 1 and 2, is similar to the right end section 5a just described, differing merely in that it is of formation inverse thereto and the right hand web 61) has its tie engaging feet I3b at the right, the same as the feet |3b of the left end web 6b, which Web 6b connects the diverged parts lb and 8b of the guide elements.

This left end web 6 and these flanges I51) and IBb have openings which register when the guide elements of the sections are in alinement; and the flanges I 5 and I 5a. and I6 and Ita likewise have openings registering when the guide elements of the middle and right hand sections register. Bolts I! through the registering openings hold the three sections rigidly together, preferably having lock washers I7 under their nuts I?" as seen in Fig. 6.

The outer guide elements I, Ia and lb thus alined as a unit, extend a considerable distance above the horizontal plane of the top of the track rail head 9a, and are preferably of such depth throughout their lengths as to extend down close to the tops of the ties; this ample depth giving them strength, and their cross section being slanted outward in downward extent so that their lower edges clear the edge of the rail base I0. This cross sectional shape also adds to the strength of these elements, which must guide the wheel I8 by engagement with the outer face of the wheel rim portion. These elements extend along the rail head 9a so close thereto as to cause the wheel I8 to travel with its flange I9 spaced a considerable distance inward away from the inner side of the rail head 9a.

The innerguide elements 8, 8a. and 8b, alined in their assembly as above explained, have their tops substantially in the plane of the top of rail head 9a; and they also are of suchdepth as to extend down close to the tops of the ties, and

sufficiently close thereto to prevent the wheel J traveling with its flange I9 an excessive distance from rail head So, for reasons to be explained.

As shown in Figs. 1 and 2, four lubricating devices are provided, at intervals along the guide "structure; each comprising a nozzle casing re-= ceiving lubricant from a respective conduit 2 by operation of the reservoir mechanism understood according to the previous reference to my prior patent. One of these lubricating devices is shown in detail in Fig. 5; and it will be understood that the others are duplicates of it. As here seen, the lower edge of the inner guide element B'has a recess 29 admitting the nozzle casing 2I, the lower end of which has the conduit 2 leading up into it, so that the casing 2!, curving around the edge of the rail base It toward the middle of the rail, is accommodated, to further extend upward, becoming much narrower transversely of the track and somewhat wider along the track, so that its top end forms a nozzle 22 standing closely along the inner side of the rail head So. with its top outlet end slightly below the plane of the top of said rail head 90.. Also, preferably, the inner wall 22 of this nozzle is not extended up as far as the outer wall 22" thereof next to the rail head 90.. This results in the lubricant being discharged, not vertically, but over toward the wheel flange I 9, in the form of a dab A, Fig. 5, which is directed into the throat [9 at the junction of the working face of the flange I9 with the tread I8 of the wheel I8, to pass toward the periphery of the flange I9 and not appreciably to pass onto the wheel tread I8.

- The nozzle casing 2| has ears 23 extending from its opposite sides along the inner guide element 8, to which these ears are secured by bolts 24v extending through the guide element 8 and through bosses 23 on the other side of the element 8, which seat the nuts 24 of these bolts.

The nozzle casing thus is rigidly mounted, to maintain the location of the nozzle 22 with relation to the rail head 9a; yet without any attachment to the track rail 9. It will be seen that it is not necessary to mutilate this track rail 9 in any way; as the guide structure is fastened to the rail merely by extension around the edges of its base I8, and the lubricant discharge means is supported by the guide structure.

To lubricate the engaging surfaces of the outer guide element I and the wheel I8, a small tube 25 leads from the lower part of the nozzle casing 2! out under the rail 9 and guide element 1, up along the outer side of this guide element I, and then into a socket 26 in a boss projecting out from the guide element I, which socket is the outer end of a passage 21 through the guide element I, opening through the inner working surface thereof. The inner guide element 8 the device.

preferably is similarly lubricated through a tube 28 leading from the inner sideof the nozzle casing 2| up into-a socket 29 in a boss projecting from the inner guide element 8, which socket is the end of a passage 38 through guide element 8, opening on the working surface. thereof which is engaged by the. inner face of the wheel rim portion. I

The arrangement just described has an advantage in addition to the primary one of lubricatingthe' guideelement, in thosev cases where the curve of the track, the outer rail of which is to be lubricated, has a guard rail running along its inner side, as for example the sharp curves on elevated or under-surface railroads in cities. Portions of the lubricant supplied for the inner guide element 8 will be carried by the wheel I8 on its inner face, and spread on such a guard rail, so that both the main track rail and the guard rail of the curve are lubricated. 'W'h'en the wheel I8 is guided by my device as above explained, the opposite wheel Illa being unitary with wheel I8 by connection of the axle 3|, will travel with its flange I9a very close to the opposite track rail 32, as indicated in Fig. 3.

Itis preferable that this opposite flange Illa not be crowded against rail 32, in the interest 'the Wheel tread I8 would receive most of the dab A of lubricant, instead of the throat I9, where the lubricant is most needed. It of course is not prohibitive to permit the opposite rail 32, coacting with opposite flange I960, to act as the limiting means, allowing the inner guide element 8 to be eliminated; the wheel I3 being allowed a little more axial play by increasing the gaugeywith a little more allowance of discharge to thewheel tread I8; and I wish it to be understood that such a, modification is within the scope of my invention.

- As indicated by the arrow in Fig. l, the wheel is traveling to the left, entering the device, which leads toward the curve 33, the beginning of which is indicated past the left hand end of The rods 3 are positioned to the right of the respective nozzles 22; being depressed by the wheel flange I9 just as the throat 1 I9 of the flange starts over the nozzle 22.

This results in dabbing the portion A of lubricant, understood to be of somewhat thick consistency, into the throat I9. Each succeeding nozzle 22 will dab such a portion onto a succeeding segment of the flange throat I9; so that when the wheel! passes to the left out of the device, it will have at intervals around it, in the throat I9, such dabs of lubricant. Then, when the wheel I8 passes onto the curve 33, where it is no longer guided by the device, the'centrifugal action on the pair of wheels and their axle causes the wheel flange I9 to bear close to the rail 9, so that the throat I9 smears the dabs A of lubricant along the rail, from its inner upper corner down along the inner face of its head So a slight distance. The dabs thus become a continuous coating of lubricant along those areas of the rail where it is most needed, and of course also become continuous around in the throat 19 which is'the area of the Wheel where the lubricant is most needed. The lubricant is kept away from the tread l8 of the wheel as fully as is practicable, as it is there wasted, and also is a detriment if spread on the top of rail head 9a, tending to cause slippage of locomotives or like motive apparatus.

It will be understood that the discharge mechanism of the reservoir I, in each instance, may be so adjusted as to deliver portions A so nearly the right size that there is a minimum of waste of lubricant. My present invention further contributes to this attainment by insuring that the nozzle 22 will not be worn or distorted, so that it will afford a certain required outlet capacity and thus facilitate the exactness of the discharge adjustment.

The rods 3 are bent so that their lower parts pass the edge of the rail base l and their upper ends are in the path of the wheel flange [9, as best seen in Fig. 5. Also, as seen in Figs. and 6, lips 34 preferably are cast on the inner guide element 8, straddling the upper end part of rod 3, with their ends bent partly around the rod, forming a guide for the rod 3. It will be understood that each rod 3, associated with the other nozzles 22 and inner guide elements 811 and 81), has the arrangement and guidance just described. Although not shown, since it is of minor importance with my present invention, such formation and guidance may be provided for the rods 4, before mentioned as operating pneumatic mechanism for forcing the lubricant from the reservoirs l, as described in my prior patent mentioned.

The example of Fig. 4 is useful where a limited amount of lubrication only is required, as at switch turn-outs and the like. Such a short structure may be one casting 35, with the end webs 36 connecting the outer guide element 3! and the inner guide element 38, by extension under rail 39; these webs being understood to fit around the rail base 4|] in the manner of the webs previously described, with lugs 36a. and 36b engaging over the edge portions of rail base 40. Feet 31a and 38a, understood to extend from the lower edges of the guide elements 31 and 38, respectively, serve to attach the structure to the cross ties M. The arrangement of the nozzle 22, guide element lubricating tubes 25 and 28, and operating rods 3 and 4 will be understood to be substantially that of the previous example.

In the modification of Figs. 7 and 8, rails 4| and 42 form the outer and inner guides, respectively, and are welded to the upper ends of brackets 43 of C-shape, which straddle under the rail 9, with lugs 44 and 45 engaging over the edge parts of rail base ID, as do the web lugs of the first example. The nozzle casing 46 has ears 41 secured by bolts 48 to an edge part of the base of the rail forming the inner guide 42, and its nozzle 49 projects upward beside the rail head So, and it has tubes 50 and 5| leading to passages 52 and 53 through the heads of the guide rails 4| and 42, respectively. Each bracket has feet 54 to engage the top of the tie [4. The operating rod 3 is guided in a hole in the inner guide rail base, and its upper part is bent to lie in the path of the wheel flange I9, other parts of the wheel being numbered as in the first example; and the device being understood to operate as described in connection with that example. Only one bracket 43 is shown,

but it will be understood that the plurality of brackets would be arranged substantially as are the webs of the integral cast structure of the first example. The entire structure may be continuous from end to end, or sections may be made up of the rails and brackets, suitably secured together at their abutting ends.

In any of the examples, the device is applied to the rail by sliding it onto one end thereof and therealong to the desired location, while the rail is propped up from the ties; after which the rail is lowered and secured to the ties by the spikes I40, at those ties not under the device, and by spikes l4b through feet [3, I311, I317, or 3111 and 38a, or 54, as the case may be. With the guide structure made up of sections, as the sections 5, 5a and 5b of Figs. 1, 2, 3, 5 and 6, the middle section 5 is first slid onto the rail base, to a place previously marked on the rail for correct location; then the end sections 5a and 5b are slid on until they abut the middle section 5. The sections then are bolted together before lowering the rail and spiking as just described. It will be understood that the parts may fit the rail loosely enough to be slid or driven along it, especially if a suitable lubricant is applied to the rail base ID; yet the'parts will not be so loose that the rail will not be properly supported, per se and in relation to the guide elements, with sufficient firmness and accuracy for the purpose of my invention, and for safety. It may be considered that my guide elements take the end thrust of the wheels, relieving the track rail; and that this thrust is only that of the two wheels and. their axle, and not that of the load on the wheels, as is the case when the wheels are traveling on the curve.

The castings in any of the examples, as the integral guide and web construction of Figs. 1 to 6, inclusive, or the brackets for the guide rails in Figs. 7 and 8, are preferably of high strength alloy steel, such as is used in track appliances successfully, for other purposes. The guide structure thus may be amply strong without excessive weight. The formation of the recesses that receive the rail base, in the webs or brackets, may be by simply coring and hand fitting to a model rail base in the shop; or these recesses may be milled or broached to shape for more exact fitting to the track rail.

It will be understood that where there is twoway traflic on the curve, such a lubricating apparatus may be provided at both ends of the curve, within the tangents leading thereto, with the nozzles and the operating rods arranged accordingly. Also, the length and number of nozzles of the device may be increased over that shown in Figs, 1 and 2, or may be decreased. Other modifications, not herein referred to, may occur in practice.
