DEVICE FOR RAISING THE BOXES OF RAILWAY-CARS.

Specification of Letters Patent.

Patented Oct. 1, 1907.

To all whom it may concern Be it known that we, WILLIAM F. BENTLEY and EUGENE B. MILLER, both citizens of the United States, residing at Baltimore, Maryland, and Keyser, in the county of Mineral and State of West Virginia, respectively, have invented certain new and useful Improvements in Devices for Raising the Boxes of Railway- Cars, of which the following is a specification.

This invention relates to improvements in means for raising the boxes of railway cars for the purpose of renewing the brasses.

One object of the invention is to provide an improved construction of lever mechanism by means of which the lifting operation may be reliably effected without the liability of becoming displaced during the lifting operation.

Another object is to provide a lifting bar which shall be sustained by one end in such a way as to hold the wheel down while a lifting device may operate on the opposite end.

Another object is to provide a movable device between the lifting bar and the box whereby to obviate a frictional contact between the bar and box during the movement of the bar.

Another object is to provide a construction whereby the device may be quickly locked in position with respect to the wheel and rail to avoid accidents to the operators by the device shifting upon receiving the load.

Another object is to provide a construction of device which may be connected to and sustained by the rail so as to avoid the necessity of blocking and forming a foundation and the delays incident thereto, and still other objects and advantages will be hereinafter referred to. i

The invention is illustrated in the accompanying drawings in which,

Figure 1, illustrates a portion of an axle, wheel and box of a railway car with my improved device in position to raise the box. Fig. 2, shows an end elevation of the same,-the jack and a portion of the lever being removed to clearly show the track, wheel and box engaging devices. Fig. 3 illustrates a sectional detail view of the wheel engaging device shown in Figs. 1 and 2. Fig. 4 shows a plan view of the mechanism for holding the device in proximity to the rail to prevent its shifting when receiving the load. Fig. 5 illustrates the jack and lever,the latter being held in position beneath the box by a modified form of device, and Fig.

6, illustrates a side elevation of the device shown in Fig. 5.

In the drawing, 1, designates the rail or track, 2, a wheel resting thereon, 3, the axle and, 4, the box at the outer end of the axle which rests on top of the axle in any well-known manner so that the brasses in the upper side of the box may take over the axle. The present invention is designed to enable the boxes to be easily elevated with respect to the axle in order that worn or broken brasses may be removed and new ones substituted but in elevating the boxes to also hold the wheels down on the rails and thus prevent their displacement.

The means or devices for engaging the wheel may vary but in the form of device illustrated in Figs. 1 to 4 inclusive we employ a block, 5, having a flat base, 6,

against the side or web thereof and beneaththe head.

This block is provided with a recess, 7, at one side which receives the rim edge, 8, of the wheel so its upper portion, 9, may overhang or project over said rim so as to be engaged with the latter as will presently appear. The upper portion, 9, of the block has a bore or hole, 10, which extends in a slightly inclined direction and opens at the upper overhanging side of the recess and a pin, 11, fits in said bore and projects downwardly into the said recess, 7, so that its lower end may rest on the shoulder, 12, adjacent the rim of the wheel, as seen in Figs. 1 and 3.

The pin, 11, may have any desired cross-sectional shape and the bore, 10, will be correspondingly shaped, but in the present instance the bore and pin are circular and the pin is provided with a slot, 13, which extends in a longitudinal direction while a guide pin, 14, extends crosswise of the head and through the slot of said pin, 11, to prevent displacement of the latter. A cross-slot, 15, is provided in the head at the upper end of the pin, 11, and the upper surface, 16, of this slot is beveled so that a key, 17, may be entered into the slot between the beveled surface, 16, and the upper end of the pin, 11, as clearly seen in Fig. 3. The object of the bore pin and slot construction is to provide for longitudinal adjustment of the pin in order that when the block is fitted up against the rail and over the rim of the wheel the pin may be forced down on the shoulder, 12, by the entering of the wedge or key, 17 at the upper end of the pin and thus hold the wheel down on the rail during the lifting operation.

The upper end of the block, 5, has a central vertical cross-slot, 18, and at one side a pin, 19, extends through the block and across the said slot forms a fulcrum for a lifting lever, 20, which will now be described. This lever is provided at one end with a notch, 21, in its bottom edge which may be seated on the pin, 19, as shown in Fig. 1, and it is also provided with a perforation, 22, through which the pin may be inserted to form a pivot connection between the block and lever if it is desired to do so instead of using the bottom notch. Adjacent the block the lever is also provided in the present instance with side brackets, 22, having perforations, 23, in which aroller, 24, is looselyjournaled. This roller may however be otherwise mounted with respect to the lever, the main object being to sustain a roller at such position on the lever that it will contact with the bottom, 25, of the box, 4. The lever may vary somewhat in length but when it is first placed in position beneath the box its operating end, 26, will preferably lie close to the ground or in a plane considerably below the bottom of the box, as seen in Fig. 1.

Any suitable power may be applied to the operating end of the lever to lift it but in the present instance we show a suitable jack, 27, having a vertically movable foot, 28, which may be elevated beneath the end of the lever by the operation of a bar, 29.

During the lifting operation the roller, 24, will easily roll along the bottom surface of the box whereas a stationary object would have to slide and the result is that the lifting operation is much more readily accomplished by the employment of the roller.

It is important that during the lifting operation the block, 5, be locked in some suitable, reliable and convenient manner to prevent it from working away from the rail and wheel and thus dropping the load and in order to prevent this we have provided means for looking or tying the block to the rail. This mechanism is illustrated in Figs. 1, 2 and 4 of the drawings and by reference thereto it will be seen that at the lower end the block is provided with a laterally-projecting arm, 30, having a horizontally-extending slot, 31. A bar, 32, projects through said slot and each end of said bar is provided with a clip, 33, to which links, 34, are connected. Rail engaging hooks, 35, are carried by the links and these hooks are spaced far enough apart to project beneath the wheel at opposite sides of the block as seen in Fig. 2. In order to quickly and securely stretch the links and hooks in a direction at right angles to the rail and thereby draw the block, 5, up against said rail we insert a wedge or key, 36, in the slot, 31, between the block and bar, 32, and by driving said wedge in place effect the result desired.

In Figs. 5 and 6 we have illustrated a slight modification of the invention, the modification consisting en tirely in the manner of sustaining or providing a fulcrum for the inner end of the lifting lever, 20. In this latter construction we dispense with the block, 5, and provide a central rim engaging hook, 37, from which a link, 38, hangs and we sustain an equalizing bar, 39, from said link. Chains, 40, hang pendently from each end of the equalizing bar, 39, and a fulcrum bar, 41, is sustained edgewise at the lower ends of said chains so as to project beneath the box, 4. When the equalizing bar is in position the notch, 21, in the operating lever, 20, is fitted over the upper edge of said bar and the lifting operation is carried on as previously described.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is,-
