ATTACHMENT FOR FREIGHT-CARS.

SPECIFICATION forming part of Letters Patent No. 621,278, dated March 14, 1899.

Application filed April 21, 1898.

To all whom, it may concern:

Be it known that I, ESTEN PELOUBET, a citizen of the United States of America, residing at Alexander, in the county of Pulaski and State of Arkansas, have invented certain new and useful Improvements in Attachments for Freight-Oars; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is an improvement in devices for use in loading lumber into box-cars or storehouses and unloading therefrom, the object of the said invention being to provide a roller which can be readily and conveniently adjusted to different heights in the doorway of a car or storehouse, and thereby assist in the operation of running the lumber into and out of the same.

In loading lumber into box-cars it is customary to nail a strip or cross-piece in the doorway and run the boards over said crosspiece, the latter being knocked off and attached at a higher elevation as the height of of the stackin the car increases. This method is very objectionable in that it not only results in destroying the door-jambs by making a great many holes,- but also necessitates the loss of considerable time in readjnsting the strip or cross-piece. In order to overcome these objections and also lessen the labor of running boards into and out of the car, I have devised a roller the length of which can be readily adjusted to accommodate the width of doorway and also facilitate the operation of adjusting said roller with respect to height, the roller having'a bearing at its ends in plates or sockets attached to the jambs.

With the above objects in view my invention consists, primarily, of a roller adjustable longitudinally, together with bearings for the ends of the roller.

The invention further consists in the particular construction of the roller fully described in the following specification.

In the accompanying drawings, which form a part of the specification, Figure 1 is a View showing the application of my invention. Fig. 2 is an enlarged detail view of the roller.

Serial No. 678,415. (No model.)

Fig. 3 is a longitudinal sectional View of the roller. Fig. 4 is a transverse sectional view.

IVith reference to said drawings, A designates the main part or outer cylinder of the roller, which is of less length than the width of an ordinary doorway and is preferably made of steel with a smooth outer surface.

In one end of this cylinder or tube is welded a collar B, having a threaded opening b extending through the same on a line with the longitudinal axis of the cylinder, the other end of said cylinder being left open to receive a cylinder or tube O, adapted to fit snugly within the same. This inner tube is of less length than the cylinder or outer tube, and welded or otherwise held in the inner end of the same is a collar D, having a threaded opening 61 through its center of a size corresponding with the threaded opening b and adapted to register therewith, for the purpose hereinafter specified. In the opposite end of the tube O is fixed a spindle or stub-axle E, the outer end of which is tapered to a point, as shown, and the body portion provided with a transverse'opening or hole 6 for the insertion of a bar or lever in turning said tube. These tubes form practically an extensible tube or roller of two telescopic sections, the inner tube carrying a stub-axle, forming one end bearing, while the other end bearing is formed on the end of a threaded rod F, which is turned or screwed through the threaded openings 1) and d and serves to adjustthe tubular sections with respect to each other to increase and diminish the length of the extensible roller. The adjustment is held by a binding-nut. F, while the endf is tapered to a point, forming a stubaxle or spindle similar to the one carried by the inner tube. By having the inner tube fit snugly into the outer tube the roller, though consisting of several parts to provide for the required longitudinal adjustment, is strong to withstand the weight of the boards or beams that will be passed over the same in use.

In connection with the extensible roller hereinbefore described bearing-plates G are secured to the side jambs of the door through which lumber is to be passed and present tapering sockets g to receive the correspondingly-shaped ends of the stub-axles or spindles, it being understood, of course, that several sets of the fixtures are attached at different elevations and arranged to support the roller either horizontally or at a slight angle. Instead of fixtures metal bars with hearingsockets may be provided.

In adjusting the roller in position across a doorway the inner tube is first screwed into the outer tube to the required extent, and after inserting the stub-axle F into its bearing plate or opening the said inner tube is then screwed outward to bring the other stub-axle into the opposite bearing-plate. This operation can be readily eifected to quickly adjust the roller to accommodate the height of the stack of lumber in the car, and by placing the said roller at an inclination it will serve to lead the lumber toward either end of the car, according to the inclination of the roller.

The roller provides a device which is particularly adapted for loading lumber into freight-cars and unloading therefrom, greatly facilitating the operation, and being strong and durable will be of comparatively small expense. The roller turns upon its axis in the hearings or fixtures in the door-jambs, and any wear on the bearing-points or stubaxles can be readily taken up by re-dressing them, though this will be seldom required, as the bearings will be made of hardened steel, and the shape of the bearings tends to reduce friction.

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

1. An extensible roller for the purpose set forth, comprising two telescopic sections adj ustable upon each other longitudinally, means for holding the adjustment of said sections, and bearings for the ends of the roller, substantially as shown and described.

2. An extensible roller for the purpose set forth, comprising sections adjustable upon each other longitudinally, means for holding the adjustment of said sections,tapered points forming the ends of the roller, and bearings having sockets corresponding with the tapered ends, substantially as shown and described.

3. An extensible roller for the purpose set forth, comprising an outer tube or cylinder, a second tube or cylinder adjustable within the outer tube or cylinder, and bearings for the ends of the roller, substantially as shown and described.

4:. An extensible roller for the purpose set forth, comprising an outer tube or cylinder, a second tube or cylinder adjustable within the outer tube or cylinder, means for holding the adjustment of the cylinders upon each other, and bearings for the ends of the roller, substantially as herein shown and described.

5. An extensible roller for the purpose set forth, comprising an outer tube or cylinder having a collar in one end with a threaded opening therethrough, a second tube or cylinder adapted to fit snugly within the open end of the aforesaid cylinder and provided with a eollarat its inner end havingathreaded opening corresponding-with that in the outer cylinder and registering therewith,a threaded rod adapted to engage the said openings, and a binding-nut on the threaded rod, substantially as shown and described.

6. An extensible roller for the purpose set forth, comprising an outer tube or cylinder, a second tube or cylinder fitting within the other tube or cylinder, a stub-axle on the outer end of the inner cylinder, a rod connecting the tubes or cylinders adj ustably to each other, and a stub-axle formed at the outer end of said rod, substantially as shown and described.

7. An extensible roller for the purpose set forth, comprising an outer tube or cylinder having a collar in one end with a threaded opening therethrough, a second tube or cylinder fitting snugly within the open end of the aforesaid tube or cylinder and provided with acollar at itsinnerend havingathreaded opening corresponding with that in the outer cylinder and registering therewith, a tapered stub-shaft at the outer end of the inner cylinder, a threaded rod engaging the'threaded openings of the cylinders and formed into a tapered stub-axle or spindle at its outer end, and a binding-nut on the threaded rod; together with bearing-plates having sockets to receive the tapered end bearings of the roller, substantially as herein shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

ESTEN PELOUBET.
