E. J. M NEILL JOURNAL JACK BLOCK AND WHEEL CLAMP Filed March 10. 1925 arm Patented Apr. 1, 1924.
UNITED STATES EDMUND tr. McNEILn, or BALTIMORE, MARYLAND.
JOURNAL JACK BLOCK AND WHEEL CLAMP.
Application filed March 10, 1923. Serial No. 624,187.
To all whom it may concern:
Be it known that I, EDMUND J. MGNEILL, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented a certain new and useful Improvement in Journal Jack Blocks and Wheel Clamps, of which the following is a full, clear, and exact description.
This invention is in the nature of an improvement on the journal jack-block and wheel-clamp patented to Charles 0. Vest, June 21, 1921, No. 1,382,332.
The invention consists in a journal jackblock and wheel-clamp in which the clamp is freely movable in the direction of its length in the jack-block or base-piece and is provided with ratchet teeth adapted to engage complemental portions on the basepiece to hold the clamp in adjusted position, as I will proceed now to explain and finally claim. V
In the accompanying drawings illustrating the invention, in the several'figures of which like parts are-similarly designated, Figure 1 is a perspective view. Fig. 2 is a partial section and elevation illustrating the invention in use. Fig. 3 is a longitudinal section. Fig. 4 is alongitudinal section of one end of the base-piece with the wheelclamp removed. Fig. 5 is a front elevation, and Fig. 6 a side elevation of the wheelclamp detached.
As in the patent referred to, so here, 1 is a car wheel, having the ordinary or any approved rim 2. 3 is a portion of an ordinary or approved axle-box. 4 is a cross section of a track rail. 5 is any ordinary or approved lifting-jack. V
The implement of the present invention comprises a j ack-block or base-piece 6, which may be made of metal and supplied at one end with a suitable handhold 7 for handling the implement. At its opposite end this base-piece is provided with an outwardly inclined upright 8 slotted centrally at 9 and provided with the upwardly flaring grooves 10 extending from top to bottom. The horizontal portion of the base-piece is provided with a stop-lug 11, and the upper portion of the upright is provided with any suitable number of teeth 12 extending transversely across the slot 9 and offset from the grooves The wheel-clamp 13 is an inclined structure, complement'al to the inclination of the upright 8, and having the shank portion 14 adapted to fit in the slot 9 and having any suitable number of laterally projecting lugs 15 adapted to engage the grooves 10, and also having a recess 16 adapted to cooperate with the stop-lug 11 to limit the downward movement of the wheel-clamp in the upright. The face of the shank isprovided with ratchet teeth 17 complemental to'the ratchet teeth 12 of the upright and adapted to engage the latter to hold the wheel-clamp in adjusted position with relation to a wheel with which it is engaged, as indicated in Fig. 2. V The wheel-clamp is arranged in the upright loosely so as to have perfect free. 2'
dom of longitudinal movement and also so as to be capable of movement toward and from the teeth 12 to engage and disengage such teeth. The wheel-clamp is held from escape upwardly from the upright by any suitable stop, as for example a screw 18. Of course this screw may be replaced by a rivet or other device.
as shown in Fig.2, tov serve as a hold-down for the wheel while the journal box is being jacked up. j
Not only does the present invention differ from the structure shown in the patent referred to with respect to the construction, arrangement and operation of the wheelclamp, but it also diflers in the strengthening of the upright of the base-piece by connecting its upper ends by means of the cross piece 20 on the back of which are located the teeth 12. This cross-piece is offset so that in conjunction with the slot and taperclamp having a shank provided with lateral The upper end of the shank 14 has the outwardly projecting lip. 19 shaped to conform, at least vapproximately, to the back ofthe riinl2 of the wheel lugs adapted to engage the grooves, a wheelengaging lip, and transversely arranged teeth adapted to cooperate with the teeth on the upright to hold the wheel clamp in adjusted position. 2. A journal jack-block and wheel-clamp,
having a base-piece to support a lifting-j ack,
' said base piece provided at one end with an of transversely arrangedteeth crossing said outwardly inclined upright having a longitudinal slot and upwardly tapering grooves adjacent to said slot and a suitable number having a base-piece to support a lifting-jack,
said base-piece provided at one end with an outwardly inclined upright having ailongitudinal slot and upwardly tapering grooves adjacent to said slotvand a suitable'number. of transversely arranged teeth crossing said, slot, a correspondingly inclined wheel-clamp.
having a shank provided with lateral lugs adapted to engage the grooves, a wheel-engaging lip, and transversely arranged teeth adapted to cooperate with the teeth on the upright to hold the wheel clamp in adjusted position, said base-piece having a lug projecting into the slot and said shank having a recess to cooperate with said lug to stopthe descent of the wheel-clamp, and said shank having a stop to prevent the upward escape of the wheel-clamp. V a 4. A journal jack-block and wheel-clamp,
having a base-piece to support a lifting-jack,
said base-piece provided at one end With an outwardly inclined upright having a longi-' slot and provided with transverse teeth adapted to engage the teeth on the crosspiece. 7
5. A journal j ack-block and wheel-clamp,
having a base-piece to support a lifting-j ack,
said base-piece provided atone end with an outwardly inclined upright having: a longitudinal slot and upwardly tapering grooves adjacent to said slot, said upright provided with an oifset crossspiece bridging the slot and having a suitable number of transversely arranged teeth, and a wheel-clamp slidably mounted in said grooved upright within the slot and provided with'transverse teeth adapted to engage the teeth on the cross-piece, the tapering grooves and the o dset cross-piece affording ample room for the movement of the wheel-clamp intoand out of engagement with the teeth on the upright.
In testimony whereof I have hereunto set my hand this-9th day o-fMarch,A. D. 1923.
EDMUND J. 'MoNEILL.
