'ALONZO HARRIS, or ATroomr-rlmriors, ASSIGNOR .OF ONE-HALF TO i oTro'scH LLiNc, or 'MATTOON, ILLINOIS.

I JOURNAL-BOX H OlST.

'- Tow/ll whom it may concern:

zen of the United States, residing at Mat- I toon,; county of ,Coles, and State of Illinois,

5 have invented certain new and useful .Im-

provements in J ournal-Box Hoists, of which the following is a specification.

. The object of this invention is to provide means for lifting a car-truck frame without the necessity for applying jacks or liftingscrews, which device is applicable to all styles of trucks and may be readily set up in position foruse and which will be strong, durable, and easily applied and operated.

Another object of the invention is to obviate the possibility of injury to the truck mechanism by carelessness in the use of the device, and the final object is to simplify the construction-and arrangement of the parts andincrease the efficiency of the device correspondingly.

The invention consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of the device, showing the method of using the same;.Fig 2, a cross-sectional elevation showing the hoist in proximity tothe rail, and Fig. 3a top or plan view of the skid with the shoe mounted thereon.

The hoist consists, essentially, of two parts' an incline or skid 1 and a slidable shoe 2. The incline or skid is preferably of I formation, having upper flanges 3 and lower flanges 4, and an intermediate web 5. Formed on the under face of the lower flanges are arranged a plurality of teeth or pins 6, which are suitably spaced to be inserted into adj ac'ent ties. As shown, the skid or incline is of sufficient length to bridge the distance between three ties, although the device may 4 be longer or shorter, as desired, and the forward upper end 7 of the skid or incline is rounded to permit the shoe to slide over the end of the skid or incline without difficulty. The upper face of the incline is provided in its center with a V-shaped groove 8, extending uninterruptedlyfrom end to end of the skid or incline and being cut in the forward or 5 rounded end of the incline for a considerable distance. The groove is adapted to receive a Specification of Letters Patent.

\ /shaped rib 9 on the under face of the shoe, and the shoe is provided at its forward end with a stop or abutment 10.

In use the device is positionedadjacent to and outside of a rail by inserting the teeth or pins into the top surface of the adjacentties, after which the truck-frame to be raised is brought into position for the journal-box to rest upon the top face of the shoe and abut against the end stop, after which the truck is carried or drawn forward, which compels the forward travel ofthe shoe along the incline by reason of the contact of the stop or abutment against the journal-box, and this travel of the shoe raises the shoe and the truckframe supported thereby. The groove 9 extends from end to end of the incline or skid, and the forward or u per end of the groove is unobstructed, so that the shoe will slide over the end of the skid or incline in case the truck is drawn forward too far, which permits the parts to drop into place without injury, and the curvature of the forward end of the skid permits this sliding over or tilting of the shoe in an easy and gradual manner, which .obviates all danger of breakage or injury. If the forward end of the slot'or groove were obstructed or terminated back of the end of the skid or incline, an excess movement of the truck would tend to tilt up the rear end of the skid or incline by reason of continued pressure against the forward end, and this tilting might have the effect of derailing the truck or causing serious injury. By allowing the shoe to slide over in the manner indicated the danger of such derailing or injury is obviated and the value and efiiciency of the device thereby increased.

by Letters Patent, is- 1 ,1

1. A journal-box hoist comprising an incline or skid having in its upper face an uninterrupted longitudinally-extending groove open at the forward end, and a shoe provided with a rib adapted to travel in the groove, substantially as described.

2.. A journal-box hoist comprising an incline or skid having in its upper face an uninterrupted longitudinally-extending groove open at the forward end, ashoe provided with a rib adapted to travel in the groove,

v to travel 1n the groove, substantially as deand having a sto or abutment adapted to I to travel in th position a journa -boX, substantially as described.

3. A journal-box hoist comprising an in cline or skid having a rounded forward upper corner and having in its upper face alongit1idinally extending uninterrupted groove or channel conforming at its forward end to the curvature of the upper corner, in combinationwith a shoe provided with a rib adapted scribed.

-' 4. A journal-box hoist comprising an in- I cline or skid having a rounded forward upper corner and having 1n its upper face a'longitudinallyextending uninterrupted groove or channel conforming at its forward end to the curvature of the upper corner, in combination with a shoe provided with a rib adapted ward end a stop or abutment ada )ted to position a journal-box, substantia ly as described.

5. A journal-box hoist comprising an ine groove and having in its for- 2c cline or skid and a shoe adapted to travel on 25 .the upper face of the skid, one of the members being provided with a rib and the other with a groove, the rib and groove adapted to ALONZO HARRIS.
