MOUNTING FOR CAR-WHEEL JACKS.

Application filed December 14, 1923. Serial No. 680,712.

ably holding a car wheel against movement relatively to a supporting rail and which also provides means whereby a jack may be supported in a desirable position with respect to a part of the wheel supporting structure.

A further object is to provide a device of the character described in which the means for holding a car wheel against movement relatively to a supporting rail can be adjusted to hold car wheels of various sizes on a. rail of any one of a plurality of difierent sizes.

A further object of the invention is to provide a device of the character described which affords facilities for releasably holding a jack in adjusted position thereon.

Other objects and advantages will be ap parent from the following description, considered in conjunction with the accompanying drawings, in which-- Figure 1 is a view mainly in side elevation and partly in vertical section, showing a mounting embodying the invention in position to secure a car wheel to a supporting rail, the jack which may be supported on the mounting being omitted,

Figure 2 is a view at right angles to Figure 1, showing the mounting in rail securing position and showing a jack thereon, the jack being shown more or less diagrammatically, the rail being shown in section and a rim portion of the wheel being broken away.

Figure 3 is a fragmentary sectional view, taken substantially along the line 3-3 of Figure 1,

Figure l is a section along the line 4El of-Figure 1,

Figure 5 is a perspective view showing a rail clamping member or prised in the device,

Figure (3 is an enlarged fragmentary section substantially along the line 6- 6 of Figure 2, and

Figure 7 is an enlarged perspective view showing a spring latch member which is comprised in the device.

Referring now to the drawings and particularly to Figures 1 and 2 thereof, 1 designates a track trail supported on ties 2. 3 is a car wheel which is supported on the rail 1 in rolling contact with the latter, and which is mounted on an axle 4-. The latter ordinarily is rotatably supported adjacent to its ends in journal boxes, such as that indicated at 5 in Figures 1 and 2, the journal boxes being attached to the car frame (not shown) in any suitable known manner as by means of members such as those indicated at 6 and 7 in Fig. l.

The parts described so far are parts of a jaw which is comrailway car of ordinary construction and form no part of the invention.

it is desirable that the wheel 3 shall be secured against movement relatively to the supporting rail when the journal box 5 or any other part of the car wheel carrying structure has been elevated slightly above normal position for any purpose, as for in stance to permit of the replacement or repair of the. brasses within the journal box. Otherwise, injury to a workman engaged in repairing or replacing the brasses'within the journal box may result.

The mounting embodying my invention includes'mcans for releasably securing the wheel to the supporting rail. and also includes means for supporting a suitable shank in position to exert upward pressure against the journal. box for the wheel carrying axle, as will be understood from the following.

In carrying out the invention in the form now preferred by me, I provide a base designated generally 8 which includes. an elongated plate member 9 superposed upon a flat supporting loclr 10 and extending a considerable distance beyond one marginal edge of the supporting: block, whereby the plate member 9 will be substantially horizontal when the supporting block 10 is disposed upon one of the ties 2 so that the extending portion of the plate member 9 is in abutting relation at its end with the adjacent face of the web portion of the rail 1 the extending portion of the plate member 9 being positioned above the level of the base flange of the rail as clearly shown in Fig ures 2, 3 and 4:. A stationary clamping member or jaw 11 is disposed upon the extending portion of the plate 9 and is rabbeted at 12 to engage not only with the ad jacent face of the web portion of the rail but with the under and outer faces of the adjacent portion of the rail head. The jaw 11 is fixedly secured to the plate 9 by screws 13 or like securing devices.

The upper end portion of the jaw 11 is provided with a pair of opposite lateral. wings or extensions 14: which extend in close abutting relation to the rail head and terminate in end portions 15 which extend above the level of the rail. Each of the end portions 15 has a horizontal slot or elongated opening 16 therein, which slots or elongated openings are positioned in a plane slightly higher than the level of the upper face of the rail head.

A pair of movable clamping members or jaws 17 are provided to cooperate with the stationary jaw 11 for the purpose of securing the plate member 9 to the rail and for holding the wheel flange against axial movement relatively to the rail. Each jaw 17 comprises a block 18 which is cut away at 19 to engage with the outer face of a portion of the under face of the adjacent part of the rail head and which is provided with a shank 20 extending from the upper end portion thereof across the upper face of the rail head through the slot or elongated opening 16 of one of the extensions 15, the free end portion of said shank being screw threaded for engagement with an adjusting nut 21 and a washer 22 preferably being disposed upon the shank between the adjusting nut and the extension 15. Each block 18 carries a clamping arm 23 which is pivotally attached at its lower end to the block 18 by a bolt 2 1- or the like to swing about a horizontal axis in a plane contiguous to the outer face of the block and to the outer face of the rim flange of the wheel. Each clamping arm 23 may be releasably held in a desirable angular relation to the horizontal by tightening the bolt 2% so that the clamping arms 23 may be positioned in engagement with the outer faces of the flanges of wheels of different diameters. A stop member on each of the blocks .8 limits the swinging movement of the associated clamping arm 23 in one direction about the axis of the pivotal connection Qti'. for a purpose which will presently appear.

A standard 26 arising from the plate 9 extends vertically for part of its length against the outer face of the jaw member 11 and is secured to the latter by screws 27 or like securing devices. The standard 26 is formed above the level of the tread or rim portion of the wheel with an end portion 28 which is inclined toward the plane of the wheel and is provided with a threaded opening 29 for engaging the threaded rod or stem 30. The latter is provided at its outer end with a handle 31 and at its inner end with a clamping head 32 which is swivelel thereon. The latter is adapted to engage with the inner peripheral wall of the rim portion of the wheel when the adjusting screw rod 30 has been turned until the clamping head 32 has been forced against the inner peripheral wall, of the rim portion of the wheel.

The plate 9 is provided with a pair of spaced apart parallel guide bars 33 extending thereon alon the longitudinal edges of the plate for part of the length thereof, the guide bars 33 being joined integrally with the plate or formed separately and secured thereto in any suitable known manner, as ocsircd. The guide bars 33 have the confronting faces thereof undercut or grooved as indicated at 341- to engage with opposite lateral extensions 2 or portions of a base or bottom member 35 of a jack 36 which rests upon the plate 9 and is slidable on the latter toward and away from the jaw member 11. The jack 36 may be of any suitable known or preferred type of construction having the lateral cxtensions or portions at the lower end thereof for entering the grooves 34- of the guide members The jack therefore is shown more or less diagran'nnaticall v in the drawings. However, such jack preferably includes a handle 37 which is adapted to be grasped conveniently to effect sliding movement of the jack on the plate 9 between the guides 83 and the base or bottom member of the jack preferably has a laterally extending flange portion so that the opposite lateral extensions for engaging the grooves of the guides 33 will be provided by portions of such laterally extending flange when the ack aas been turned about its axis to any possible position. The jack may be held against movement from adj ustcd position along the guides 33 in any suitable known manner, preferably through the. agency of a substantially U-shaped spring latching clip 38 which is formed of a ma terial possessing inherent resiliency and having arms normally held in divergent rclation because of the resiliency of the component material, whereby 'ircssure will be exerted on the jack and on one of the guide members 34 when the latching member 38 is inserted in the manner of a wedge between the body of the jack and the adjacent face of the guide member. (inc of the. arms of the latching member iireferably is fashioned at its outer extremity to provide afinger ere.

hold or handle. 39 for convenience in manlpulating the latching member to place -it in latching position with respect to. the

jack and guide bar or to remove the latching member from latching position to release the jack. i

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The wing extensions 14 of the stationary jaw member 11 are of sullicient length that the elongated openings 16 may be spaced apart a distance suiiicientto permit of the shanks 20 of the movable clamping blocks being extended across a rail at opposite sides of the point of rolling contact of a wheel with the rail and then extended through the elongated openings 16. The distance between the shanks 20 of the movable clamping blocks may be varied by moving such shanks on the rail 1 and along the elongated opening 16 so that the clamping arms 23 will be positioned for engagement with the outer taces of the rim portions of wheels of different diameters. The stop members 25 prevent outward swinging movement of the clamping arms 28 beyond position to engage with the adjacent face of the rim portion ot a wheel of the largest diameter with which the device is adapted to be used. lVhen the nuts 21 have been tightened the clamping block and the stationary jaw 11 will be clamped against opposite sides of the rail head and the plate 9 will be held against movement relatively to the rail. At the same time, the clamping arms 23 will be held in close engagement with the inner taces of the rim portions of the wheels thus tending to hold the rim flange of the wheel against the inner face of the rail head and cooperating with the clamping head 32 when the adjusting screw 30 has been tightened to hold the wheel against upward movement from the rail. This clamping action on the wheel also tends to prevent rotation thereof. The jack 36 can then he slid on the plate 9 between the guides 33 to a desired position and after being secured against movement relatively to the plate 9 by use of the latching member 38 may be manipulated to exert upward pressure on the journal box 5.

Obviously, my invention is susceptible of embodiment in forms other than that illus trated in the accompanying drawings and I therefore consider as my own all modifications and adaptations of the form of the device herein described as fairly fall within the scope of the appended claims.

Having thus described the invention, what I claim is 1. A device of the character described comprising a base adapted to be positioned upon a railway track at one side of a track rail and in abutting relation to the latter,
