WILLIAM F. BENTLEY, OF BALTIMORE, MARYLAND.

MEANS FOR RAISING THE BOXES OF RAILWAY-CARS.

To all whom it may concern:

Be it known that 1, WILLIAM F. BENTLEY, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Means 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 present invention is to provide an improved construction of device which may be quickly put into position and without the necessity of providing a block or other foundation on the ground.

Another object of the invention is to provide an improved construction which will enable the lifting of the box to be accomplished by one man.

Other objects and advantages of the invention will be more fully set forth and described in the accompanying description forming part of this specification.

The accompanying drawing illustrates the invention in which,

Figure 1 shows a side elevation of a device constructed in accordance with my invention and in position to raise a car journal box. Fig. 2 illustrates a vertical sectional view of the device,the section being taken on the line 22 of Fig. 1. Fig. 3 shows a side elevation of a slightly modified form of device, and

Fig. 4 illustrates a sectional view of the same,,the section being taken on the line 4-4 of Fig. 3.

Referring to the drawings the numeral 1, designates the rail or track; 2, one of the car wheels resting thereon; 3, the axle and 4, the box which is sustained upon the end ofthe axle in any well-known manner so that the brasses in the upper side of the box may take over the axle. I

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. It is also desirable that in elevating the boxes the wheels be held down on the rails to prevent their displacement. I

111 the present instance the device is shown engaged with and sustained from the wheel, but it is to be understood that this is not essential as it may be engaged with any suitable portion of the car frame. In the form shown, this sustaining device comprises a hook, 5, which takes over the flanged rim, 6, of the wheel and the end of this hook carries a clevis, 7 of substantially a U-shape. This clevis straddles the end of the hook and a pin, 8 projects through the clevis and hook and secures the two together. Adjusting holes, 8, are also provided in the clevis so that its position with respect to the hook may be varied slightly in a vertical direction.

A bail, 10, is pivotally carried at the ends of the pin, 8

and a chain, 11, has one end connected to this bail. At the lower end the clevis is provided with an eye, 12, and a link, 13, engages the eye and sustains a horizontal equalizing bar, 14. Chains, 15, hang pendently from opposite ends of the equalizing bar and project downwardly below the bottom surface of the journal box, and the lower ends of these chains sustain a fulcrum bar, 16, in an edgewise position in a horizontal plane beneath the box. A lifting bar, 17, has position beneath the box and this bar has its inner end, 18, seated on the upper edge of the fulcrum bar, 16, while the operating end, 19 of said lifting bar projects outwardly beyond the outer end of said journal box. Brackets, 20 are provided in the lifting bar and these brackets sustain a roller, 21, which when the lifting bar is in place, will have position beneath the bottom surface of said box. It will be noted that the lifting bar, 17, is provided with an arched portion, 22, between its ends and that said portion has position beneath the box and carries the brackets and roller. A supporting bar, 23, has its lower end sustained at a point beneath the box, 4, and said bar extends upwardly and outwardly in front of the said box.

In Figs. 1 and 2 the supporting bar, 23, has its lower end, 24 pivotally connected to the inner end, 18, of the lifting bar and this bar, 23 is provided with a bifurcation, 25, forming a slot therein, and the lifting bar, 17 projects through the said slot. The upper outer end, 26, of the supporting bar carries a horizontal angle plate, 27, which is preferably pivotally mounted by means of a bolt, 28, to said end, 26. A block or nut, 29 is seated on the angle plate, 27 and over a slot or opening in said plate, and a screw, 30, extends through the angle plate freely and engages a threaded opening in the block or nut. The upper end of the screw is provided with a head, 31, which carries a plurality of operating arms, 32, while the lower end of said screw is provided with a head, 33, which is preferably carried so as to remain stationary while the screw revolves. An eye, 34, is provided on the lower side of the head and a flexible connection such as a chain, 35, hangs from the eye and has its lower end connected to the outer end, 19 of the lifting bar, 17. A short chain, 36, is attached to the upper end of the supporting bar, 23, and this chain is provided with ahook, 37, which engages with the chain, 11, carried by the bail, 8, and by this engagement of the two chains, 11 and 36, the outer ends of the bars and screw are sustained independently of any ground support. It is obvious that by turning the screw, 30, so as to cause it to travel up through the nut or block, 29, the operating end, 19, of the lifting bar will be raised and the journal box, 4, elevated by the inner arched end of said bar.

The device illustrated in Figs. 3 and 4, is precisely like that shown in Figs. 1 and 2 with the exception that the lower end, 38, of the supporting bar, 23, is sustained by contact with the rail or the wheel. In this latter form the lower end of the said supporting bar is provided with an arm, 39, which engages the rim of the Wheel, while the lower end of said bar seats against the rail. v

From the foregoing description it will be seen that the device is of such construction that it may readily be rigged and being sustained entirely independently of the ground requires no blocking to form a foundation for a jack and further, that the entire operation of rigging and operating may be quickly performed by one man.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is,

1. The combination with a lifting bar, of means for sustaining the inner end of the bar adjacent to the box and at the side of the car wheel; a lifting device at the outer end of the lifting bar and connecting the latter; means for sustaining the lifting device from a portion of the car and means for moving the lifting; device vertically to operate the lifting bar.

9. The combination with the wheel engaging means. of a fulcrum bar below the box and sustained by the wheel engaging means; a lifting bar having one end engaging the fulcrum bar; a supporting bar having one end supported below the box and its other end extending onlwardly therefrom, and a lifting device carried by the supporting bar and connected with the liftingbar.

10. The combination with the fulcrum bar below the box. of means for sustaining the said bar; a lifting bar having its inner end engaging said fulcrum bar and extending oniwardly from beneath the box; a supporting bar having its inner end sustained by the lifting bar and its outer end extending upwardly therefrom and a lifting device at the outer end of said supporting bar and connected with the outer end of the lifting bar.
