i To all 'whom it may concern:

Be it lrnown that we, WILLARD A. STORY and WILLIAM A. HALL, citizens of the United States, and residents of Chillicothe, county of Ross, and State of Ohio, have invented new and useful Improvements in Lifting- Jack-Supporting Devices, of which the following is a specification.-

This invention relates to lifting-jack supports and more particularly to devices for supporting railway-car jacks in relation to the car-wheels so as to elevate the journalboxes into position for readily removing and replacing the brasses and other internal parts of the box that are adapted to be removed and replaced upon such raising-action of the jack.

The invention consists of acar-jack suspension device comprising a pair of vertical members, a lower horizontal member connected at its opposite ends to the lower ends of said vertical members, a pair of claws each one of which is connected at one end to the upper end of a vertical member and having hook-formations at their opposite ends for engagement over the `iiange of a carwheel and a coupling-member engaging at its opposite ends the said claw-members, the whole being adapted to be swung into vertical position from a car-wheel with said vertical members at either side the journalbox and said lower horizontal member being adapted to support a lifting-jack beneath said journal-box in position for raising and lowering operation on said journal-box without any of the parts being supported elsewhere than on the car-wheel.

The details of the invention will be fully hereinafter described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation showing our invention in position in connection with a-carwheel and its ,journal-box, said car-wheel being supported on a broken section oftrack and the jack being in raised or extended position together with the ournal-box thereon so that the brass and wedge in the latter canV be readily removed 5 andL Fig. 2 is a side elevation of Fig. 1, but showing the lid of the box raised and one side of the box open, the customary brass and wedge within the box being shown in section and in position for removal.

In these views, 1 indicates an ordinary railway-car wheel having a flange 2 and the journal spindle or bearing 3.

i indicates the ordinary form of journalbox or oil-receptacle that surrounds the spindle 3 and is adapted to be raised upward 'n relation to but independent of said spindle. 5 indicates a hinged lid on the face of said box, 6 the customary wedge or key and 7 the brass, the latter intervening between the wedge and the spindle as usual.

8 indicates each one of a pair of vertical sus ension-members, preferably composed of inks suitably Aconnected together and coupled at their lower Aends by means of a plate or cross-bar 9, eyes 10 intervening between the lower ends of the members 8 and the opposite ends of the plate 9.

11 indicatesa spacer or prop suitably bolted at its outer end or body portion to the plate 9 mid-length of the latter and having a vertical, serrated face along its inner edge 12,as best seen in Fig. 2, such serrated edge 12 being adapted to engage the angular outer edge of the tread of the wheel to prevent slipping of the rop and the latter itself being adapted to old or sustanthe lower portions of the suspension-members sufficient distance kaway from the wheel to suit the desired jack-centering position thereof beneath the journal-box.

At the upper ends of the several suspension-members 8, we provide suitable claws or retaining lock-members which engage over the tread and ange ortions of the wheel and are each composed) of an outer right-angled part 13, Athat engages over the angular treadortion of the wheel, and an innerhook-s ape part 14, the latter being pivotally connected to .an upward extension on the former part 18 by means of a bolt 15 and the lower part of the member 13 being, in turn, pivotally-connected at 16 to the upper link of the suspension-member 8.

A chain or other suitable flexible coupling 17 is rovided to connect the two` claw or clamping members at the upper ends of the suspension-members 8, as best seen in Fig. 1, one end of the chain being rigidly connected to an eye 1S in the bolt 15 and the other end of said chain being in the form of a hook 19 that engages an eye 20 in the bolt 15 of the other claw or clamping member. rl'his chain is adapted to support the suspension-members from lateral play, the journal-box itself preventing the sus ension-members from play toward each ot er and the hooked end of the chain is adapted to permit the ready release of the two upper ends of the suspension-members for convenience in use.

A lifting-j ack com rising a barrel 21 and a l screw 22 is provided etween the j ournal-box and the body portion of the rop-bar 11 for expansive action between said) box and propbar for the raising of said box inrelation to the journal-spindle when it is desired to remove the brass and wedge, or either of them from the box. The barrel 21 of the jack is pointed at its lower end 23 and such point rests and turns in a socket or step in said prop-bar 11, awrench or other suitable implement being used in connection with the octagonal face of said barrel to turn the latter in either direction for raising and lowering the journal-box. The head 22a of the screw-portion 22 of the jack atly contacts with the under side of the tie-bar 24 on the truck-frame that supports the journal-boxes, thus arranging the jack in a perpendicular line beneath the center of the load to be lifted or shifted vertically in a straight line which is the desirable feature in the operation of a jack beneath a journal-box of a car-wheel and constitutes an important feature herein. Jacks as heretofore used have been subject to more or less trouble and difficulty in operation owing to the point of lift being to one side of the center of the load, thereby tilting the box and rendering it hard to remove the wedge and brass from the spindle. All this is corrected and obviated in the use of our jack-supporting device which is suspended from the wheel and the jack not rested on the ground or the ties at all, as it has been heretofore, the surface of the ground and ties being more or less uneven and not, as a rule, anywhere near level, all of which has been greatly annoying and inconvenient in the use of the ordinary form of lifting-j ack in general use.

lt will be seen that the swinging of the suspension device from the car-wheel serves to hold the latter down in place on the track, especially when the jack is being extended in the lifting operation on the box independent of said wheel.. The ordinary form of j ack, as heretofore used, has not been suspended from the wheel, but, in being supported on the ground, or on the ties, has had a tendency to allow the wheel to rise on account ofrelieving the weight from one end of the axle only whereby the removal of the brasses and wedges has been more or less inconveniently effected.

Instead of making the prop-bar or spacer a separate piece of material and attaching it to the lower plate or cross-bar 9, it is obvious that the spacer or inwardly-projecting portion of the platform part of the device can be made integral With said platform part or cross-bar 9 and a step or socket made centrally in the latter to provide for the lower pointed end of the j ack-barrel. The plate or cross-bar 9 would thus form a direct platform or seat for the uprightly-disposed jack when it is in place bemeath the tie-bar that supports the journal-box. The side suspension- members 8, 8 lean or cant outwardly from the upper ends down to said platform,

' the two-part pivotally-united claw-members being engaged over the tread and ange portions ofthe wheel so as to hold firmly in place during the action of raising the journal-box and retaining it in elevated position for removing the wedge and brass therefrom and replacing same, or other desired purpose.

Instead of making the suspension- members 8, 8 in chain-form, it is obvious that they could be made in single rod or bar form and pivotally-connected at their opposite ends to the claws and j ack-platform, respectively, but the desired iiexibility in the parts would be absent for the purpose of the necessary adjustment of the jack in relation to the journal-box and in compensating for any lack of uniformity in the position of the car on the track, or the box in relation to the truck and the car-wheel.
