JOURNALBOX JACK.

App1ication filed July 14,

To all whom itrnay concern:

Be it known that I, GEoRen TALLION, a citizen of the United States, residing at Malone, in the county of Franklin and State of New York, have invented certain. new and useful Improvements in Journal-Box Jacks, of which the following is a specification.

This invention relates to a certain new and useful improvement in jacks for lifting car journal boxes so as to permit removal and replacement of the bearing or brasses thereof.

An object of the invention is to provide a 15, jack of the above kind which may be made of lightweight material, so as to be easily handledhy one man, and wherein a munmum-number of parts are employed so that the device embraces the desired quality of simplicity and inexpensiveness of manufacture.

Anotherobject of the invention is to provide a journal box lifting jack which does not rest upon the ground, but isapplied directly to the collar of the wheel axle,

thereby doing away with blocking of the wheels, blocking from the ground up and like objectionable steps which are necessarily followed in placing prior jacks of this kind in practical use.

Other objects will appear as the nature of the invention is better understood, and the same consists in the novel form, combinatien and arrangement of parts hereinafter more fully described, shown in the accomanying drawing and claimed.

In the drawing, wherein like reference characters indicate corresponding parts throughout the several views,

'Figure 1 is an elevational view illustrating one form of jack constructed in accordance' with the present invention applied in position for elevating a car journal box,

Figure 2 is an enlarged view, partly in elevation and partly in section, of the jack shown in Figure 1, and

Figure 3, illustrates a modified form of the invention.

Referring more in detail to the drawing, and particularly to Figures 1 and 2 thereof, this form of the invention includes a substantially Q-shaped member composed of an upper arm 5, a lower arm 6, and a central or intermediate connecting portion 7. The inner end of the upper arm is notched to I simultaneously provide a collar engaging lip 1923. Serial No. 651,448.

and abutment, the lip being disposed at the top of the arm, and in aplane with the upper surface, and the abutment being formed by the vertical wall of the notch beneath said lip. WVith this arrangement, the lip is permitted to obtain a single point of contact with the peripheral edge of the collar, while the abutment bears against the flatouter face of the collar. Thus, a structure is provided, which permits the device to be used with collars of various diameters. The lower arm 6 of the jack extends inwardly beyond the inner end of the upper arm 5. It is to be observed that the upper side of theprojecting lip is a plane with the corresponding side of the short arm 5. Also, inasmuch as this lip projects beyond the end of the short arm 5, that end is permitted to serve as an abutment for resting against the outer face of the collar.

The inner end of the lower armti is provided with a vertical lifting screw 11 inserted through the arm 6 as shown in Figure 2, and suitable means is provided upon the lower end of this screw for facilitating turning of the same, such as a transverse opening 12 adapted to receive a handle bar or the like. Observing Figure 1 of the drawing, it will be seen that the proximity of the lifting screw to the wheel of the car calls for the use of a removable handle bar or the like, since the latter may he slid back and forth in the opening to accommodate the small space existing. I also prefer to provide the lower end of the screw with a polyg onal wrench engaging head, to permit the use of the wrench whenever necessary or desired. The lifting screw 11 has a swiveled plate 13 upon the upper end thereof adapted to engage the lower surface of the journal box 10 so that this plate 13 may remain stationary while the screw 11 is rotated for thereby offering comparatively little resistance to the turning of this screw. Theplate 13 is preferably detachably fastened by means of the screw 14 to a second plate 15 which has a screw stud 16 that is llJU and 2 except that the vertically movable jaw 18, instead of being in the form of a screw, is of a'well known slidable form adapted to be actuated by means of a swinging lever 19, the actuating connection between the lever 19 and the jaw 18 being of any desired form such as a cam rotated in theend of the armfi and fixed to the lever 19. As this particular form of jaw and actuating mechanism is conventional, the same is only diagrammatically disclosed. With this form of movable liftingjaw, the use of the swivel plate 13 is eliminated.

In both forms of the invention, a suitable hand hold 20j-is formed upon the connecting porti'on i so as to facilitate handling of the jack'whe'n' placing it upon the car journal or when carrying the same from place to place.

raised so as to cause the axle box 10 to -be raised sufiiciently to permit removal of the wedge 22, after which the hearing or brass 23 may be removed and replaced at will.

"Fromthe foregoing description, it will be seen that I have provided, a jack by means upper arm being provided at its free end with'rneans for engaging an axle collar, said lower arm being of a length greater than the upper arm and extending inwardly beyond the collar engaging means to dispose its end beneath the approximate center of a journal box, and a lifting device carried by the inner end portion ofsaid lower arm.

r 2. A journal box jack comprising a C- shaped member, the lower arm of which is adapted to be provided with a journal box engaging and lifting device, the upper arm thereof being substantially rectangular in cross section at its free end, and being provided at this end with a notch, which is open at its side, bottom and end, the formation of said notch simultaneously providing an abutment for engagement in the outer fiat face of an axle collar, and an extension forming a lip at the top of the arm for en gaging the peripheral edge of the collar, said lip having a single point of contact with the collar, whereby to permit the same to be engaged with collars of various diameters. In testimony whereof I affix my signature. GEORGE TALLION.
