the manner in which the ladder fastening member 24 is secured will be more clearly understood. A platform 3| is formed on the stirrup 20 for holding a hydraulic jack 32 as shown in Figures 8 and 9. The cars 33 and 34 are provided on the sides of the platform 3| to keep the jack 32 in place. The strength of the stirrup 20 is provided for by the web construction on its underside as shownin Figure 6.

In order that the operation of my hoisting apparatus may be more fully understood, reference may now be had to Figures 8 and 9 of the drawings. When it becomes necessary to remove the journal brass 35 of a journal box 36, the first step in using my hoisting apparatus is to place the arm member I l in position on the top of the car wheel [5. The cable 2! is then placed in the groove 13 on the outer end l2 and the jack 3 2 is placed in the stirrup 20 with its handle 31 toward the outside. The jack 32 is then held in position beneath the journal box 36 with its piston 4| thereagainst and the ladder fastening member 24 is slipped into position in the slotted cap 30, taking up as much slack in the cable 2| as is convenient. My hoisting apparatus is now in place and assembled for lifting the journal box 36. The jack 32 which is preferably hydraulic V is provided with a valve 40 which must be closed in order that the piston 4| may be raised and which must be opened in order to let down the piston 41 after it has been raised. After closing the valve 40, the operator operates the handle 3'. thereby operating the jack 32 and raising the piston 4!. As soon as all of the slack in the cable, 2! has been taken up, the journal box 36 will. commence to belifted thus taking the load has been replaced and the journal brass Wedge 42 properly inserted in the journal box 36, the

valve 4! may be opened and the piston. 4! thereby released allowing the journal box 36 tobe lowered. After the journal box is once more resting on the wedge 42, the hoisting apparatus can then be removed.

It will be seen that the load of the lifted journalbox 36 is carried as follows: the load is transferred through the jack 32 to the stirrup 20, the

loa-d on the stirrup 20 is supported by the cable.

2i, the load on the cable 2| is supported from the outer end 12 of the arm member H and the load on the arm member II is supported at the bearing surface l 1 bearing against the tread- I8 of the wheel It. It is further seenthat the moment of the load on the outer end [2 about the bearing surface IT is counterbalanced by the hook l4 gripping into the inside of the wheel l5.

By having the load of the lifted journal box 36 transferred to andcarried by the wheel 15,

it serves to hold the wheel H5 in place and to prevent it from rising off the track or slipping sidewise.

In the event that it may for some reason be impossible to employ my hoisting apparatus for lifting a journal box 36 as outlined above, it is possible to jack up the journal box 36 in the conventional manner. This is illustrated in Figure 10 of the drawings. As there shown, the arm member H is placed beneath the journal box 36 with its outer end 12 resting on the lower inside of the wheel l5 and with the hook l4 resting on a, block 50. The inner contour of the arm member H is such that the jack 32 can be placed thereon as shown for jacking up the journal box 36. Thus it will be seen that my hoisting apparatus may be used in practically any situation for lifting a journal box to remove the journal brass therefrom.

It will be observed that it is preferable to make the outer end 12 of the arm member H approximately the same width as the stirrup 2| However, this is a matter of design and may be varied.

It will also be understood that the hydraulic jack 32 may be replaced by other types and that the cable 2| may be replaced by a chain or other support means.

- Since certain further changes can be made in the foregoing construction, and different embodiments of the invention. may be made without departing from the scope thereof, it is intended that all matter shown in the accompanying drawings or described hereinbefore shall be interpreted as illustrative, and not in a limiting sense.

I claim as my invention:

1. Railway car journal hoisting apparatus comprising, in combination, an arm adapted to be supported by a railway car wheel and to project over the journal box of said railway oar wheel, a stirrup, a flexible cable for supporting said stirrup from said arm, one end of said cable being secured to one end of said stirrup and the other end attached to a ladder fastening mem-" ber adapted to adjustably fasten said other end to said stirrup, and a jack carried in a platform on said stirrup for lifting said journal box, the load of said lifted journal box being transferred through said jack to said stirrup, the load on said stirrup being supported by said flexible cable which in turn is supported from the outer end of said arm, the load on said outer end being supported on the tread of said railway car wheel and the moment of the downward load on the outer end of said arm about the tread support being counterbalanced by a hook of said arm which securely grips into the inside of said railw-ay car wheel.

2. A stirrup for use in connection with railway car journal hoisting apparatus having a platform for carrying a jack and adapted to be supported by a cable one end of which issecured to one end of said stirrup and a slotted cap in.- tegrally formed on the opposite end of said stirrup by which the other end of the cable is secured.

AUGUST W. DONOP.
