JAMES S. PATTEN, OF BALTIMORE, MARYLAND.

CAR-AXLE LUBRICATOR, DUST-GUARD, AND WIPER.

SPECIFICATION forming part of Letters Patent No. 641,723, dated January 23, 1900.

Application filed. March 31, 1898. Serial No. 675,894. (No model.)

To all whom it may concern.-

Be it known that I, JAMEs S. PATTEN, of Baltimore, in the State of Maryland, have invented a new and Improved Oar-Axle Lubricator, Dust-Guard, and Wiper, of which the following is a specification.

This invention is a combined axle-lubricator, dust-guard, and wiper, constituting an improvement upon that for which I have filed an application, Serial No. 633,986. The oil employed as the lubricant is held in the bottom of the axle-box, such as is in ordinary use on railroads, and is taken up and transferred to the axle-journal by a rotating roller or wheel held in a V-shape swinging hanger pivoted in the arms of springs that also support a dust-guard and hold it in place.

My improvements are embodied in various features of construction and combination of parts, as hereinafter set forth, and shown in the accompanying drawings, two sheets, in which- Figure 1 is a central longitudinal section of an ordinary car-axle box and car-axle with my improved apparatus applied thereto as in practice. Fig. 2 is a transverse vertical section of the same on line 2 2, Fig. 1. Fig. 2 is a reduced face view of the rear upper dustguard. Fig. 3 is an end view of the axle-box, part of the lid being broken away. Fig. 4 is a perspective view of the upper front portion of my apparatu s. Fig. 5 is aperspective view of the remaining portion of said apparatus. Fig. 6 is a perspective view illustrating the adaptation of the lubricant-roller hanger for ready attachment to or detachment from the arms of the supporting-spring. Fig. 7 is a rear face view of a portion of the lower dustguard and wiper. Fig. 8 is a plan view of the cast-metal blank for the lower dust-guard and wiper.

The axle as, axle-box y, and bearings z are constructed and relatively arranged in the usual way.

As in my former invention, a roller 1 is journaled in the angle of a swinging slotted V- shape hanger 2, having at its upper end lateraltrunnions or pivots 8, which are detachably connected with the free ends 4 of springarms 5. The latter are integral extensions of the curved parallel springs 6, which connect the combined rear dust-guard and wiper 7 and the front dust-guard 8 and hot-box indicator 9. The said springs 6 rest on the bottom and lower front portion of the axlebox y, as shown in Fig. 1. The angles of the arms 5 with the body 6 of the springs are suit-ably constructed to adapt them for piv-' otal connection at 10 with the rear dust guard 7, whereby the latter may oscillate and accommodate itself automatically to the axle a: and adjacent rear wall of the axle-box y. The said dust-guard 7 is a thin and duly flexible metal plate, preferably malleable castiron. The curved upper edge of the same is thickened and provided with a wiper 11, Figs. 5 and 7, formed of a leather strip which is clamped and held in place by means of flexible claws or fingers 12, formed integrally with the body of the plate, on the outer or rear side thereof, and pressed inward upon the leather strip 11. The upper edge of said strip 11 is practically flush with the edge of the plate proper, 7, and both form a wear-surface that works in close contact with the axle-journal m. The same function is performed on the upper side or half of the axle by means of a horseshoe-shaped dust-guard and wi'per 13, which is shown detached in Fig. 2 The same is constructed, like the lower dust-guard 7, preferably of flexible cast metal and similarly provided with claws for holding a leather strip 13 This dust-guard 13 is inserted in the pocket or narrow compartment y, formed in the rear end of the axle-box y, and a wooden piece or cap g is driven into the mouth of said pocket to close the same dusttight. By means of this construction and arrangement of the two combined dust-guards and wipers, one within and the other exterior to the pocket y, dust is almost perfectly excluded and the escape of oil effectually prevented.

In the further explanation of the novelty and practical importance of the improvement embodied in the construction and arrangement of the two dust-guards, as above described, I will state that the ordinary wooden dust-guard is arranged in the pocket y, and if a hot box occurs and the dust-guard thereby becomes charred or if it be rendered useless by wear or other cause it cannot be entirely removed save by first detaching the axle-box from the journal, which is an opera- ICO tion requiring considerable time and labor and involving corresponding expense. I avoid these results by combining two dustguards which are so constructed and arranged as to be detachable independently without requiring removal of the axle-box from the journal-that is to say, the lower dust-guard 7 is arranged within the box y, but outside the pocket y, and is thus adapted to be applied and removed through the mouth of the box, while the upper one, 13, is arranged in said pocket y and applied and removed through the mouth of the same, and, further, its arms or lower portions (see Fig. 2) are of such length and constructed with straight and parallel outer edges, which come in contact with the sides of the pocket, that the guard will retain its position in the pocket y without the aid of any other means or device. The said arms of the guard 13 extend below the center of the journal as, as indicated by dotted lines in Fig. 1.

As a means for removing from the journal 00 the main portion of the surplus oil taken up by the roller 1 I employ wipers formed by projections 11L on the front face of the lower dust-guard 7. (See Figs. 5 and 8.) These projections are integral hollow or grooved arms standing at right angles to the body of the plate and having elongated leather pieces 15 clamped between their parallel flexible sides, which are for that purpose pressed or bent inward to the required extent. The said pieces 15 extend along and work in contact with the journal proper, 03, at points which are opposite and immediately adjacent to the curved shoulder of the same. They thus serve to wipe off the main portion of the oil, which flows rearward along the journal, so that a comparatively small quantity reaches the point where the dust-

guards

7 and 13 are located. Both the arms 1a and claws or fingers 12 of dust-guard plate 7 (see Fig. 8) are cast with the said plate-body 7 at right angles thereto, so that the blank-casting will draw easily from the mold. The projections 12 are subsequently bent or curved upward and the sides of the arms 11 bent slightly inward to clamp the respective leather strips or pieces 11 and 15.

The construction of the two dust-guards is the simplest possible, yet the distribution of metal is such as combine maximum lightness and strength with great efliciency in use and adaptation for convenient removal.

The lower edge of the flanged wheel or roller 1 runs in the oil held in axle-box y and in close working contact with the journal 00 by means of the resiliency of the arms 5, supporting the hanger 2. The latter swinging free on its trunnions 3, the wheel accommodates itself to the journal under all conditions.

The axle 16 of the roller 1 is flattened at its ends or otherwise made polygonal and fitted in corresponding notches in the angles of the slotted hanger 2,whereby it is prevented from rotating with the roller. To confine the axle 16 securely and yet provide for its easy detachment from the hanger 2 when required for substituting a new wheel or for other purpose, prongs 17, Fig. 2, composed of flexible metal, preferably copper, are cast and embedded in the body of the hanger 2 and subsequently bent down upon the axle ends, as shown. The said prongs 17 may, however, be formed of integral portions of the hanger.

As shown in Fig. 6, the free ends 4 of the spring-arms 5 are curved to form circular bearings for the trunnions 3 of the hanger 2; but such circular bearings are not closed, a narrow space at 18 being left for passage of lateral projections 3 on the trunnions 3-that is to say, such projections 3 are pendent from the outer ends of the trunnions 3 when the hanger 2 is in vertical position and engage the side edges of the bearings 4, as shown best in Fig. 5. It is apparent that when in this position the hanger2 cannot be detached either accidentally or by design; but when the hanger 2 and wheel 1 are swung up and backward to the horizontal position shown in Fig. 6 the trunnions 3 may be separated from the bearings 4, since the projections 3 will then slide laterally through the slot or space 18, before referred to. This feature of easy connection and separation of the hanger and its bearingsis of much importance and does not afiect the efficiency of the apparatus as a whole. 1

The hot-box indicator 9, which is similar to that described in my aforesaid application, is attached to the upper outer ends of the springs 6, as in such former invention, and consists of a sheet-metal box having perforations or openings and a filling of hair, felt, or some equivalent substance whose volatile element vaporizes at a temperature considerably below that required to produce a hot box. The ends of the box proper are formed of flexible portions or sections which are bent inward after the filling has been inserted.

The front dust-guard 8 is a fiat and thin metal plate riveted to and supported by the springs 6 and made of such lineal dimensions as to exceed the size of the mouth of the axlebox y, which it is arranged to cover. It lies directly under the hinged lid U3 of the axlebox, the hinge or joint of the latter as usually constructed being sufliciently loose to allow this. The plate 8 serves to exclude dust much more effectually than the axle-box lid is capable of doing, besides aiding in holding the hotbox indicator in due position.

What I claim is-- 1. The rear dust-guard whose body is constructed of flexible metal, the same having inwardly-projecting hollow arms arranged at the opposite ends thereof and adapted for holding and securing wipers proper, substantially as shown and described.

2. The combination with the axle-journal and axle-box, of the lower rear dust-guard and wiper comprising the plate composed of flexible metal and having inwardly-projecting hollow arms, and the leather pieces arranged in such arms and clamped by the -inwardly-bent sides of the latter, as shown and described.

3. The blank for the rear dust-guard and wiper, constructed of metal having a due degree of flexibility, as specified, the same comprising a fiat curved body having a series of claws or fingers projecting from the rear side or face at right angles thereto, and the hollow arms projecting from the opposite, or inner face of the body also at right angles thereto, whereby the blank is adapted to be drawn from the mold, as specified.

4. In an axle-lubricator, the combination, with the supporting spring-arms having open bearings, of the roller-hanger having trunnions which are detachable from such bearings, substantially as shown and described.

5. In an axle-lubricator, the combination, with the supporting-springs, having bearings constructed with a space or slot as specified, of the roller-hanger having trunnions provided with projections adapted to pass through such slots when in one position and to engage the bearings when the hanger is in pendent or working position, substantially as shown and described. 7

6. The combination with spring-supports, of the V-shape roller-hanger having end trunnions or pivots provided with pendent projections, as and for the purpose specified 7. The combination with the axle-box front dust-guard composed of a thin metal plate, adapted to extend over the mouth of the axleboX, and supporting-springs connected with such plate and extending to and resting upon the bottom of said axle-box, substantially as shown and described.
