TRUNK-CASTER.

SPECIFICATION forming part of Letters Patent No. 568,535, dated September 29, 1896.

Application filed March 12, 1 8 9 6.

To all whom it may concern/.-

Be it known that I, MORITZ ISIDOR, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Trunk-Casters; and I do hereby declare the following to be a full, 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, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to obtain greater strength and durability in trunkcasters without materially increasing the cost thereof; and it consists in the improved trunk-caster, and in the arrangements and combinations of the parts thereof, all substantially as will be hereinafter set forth, and finally embraced in the claim.

Referring to the accompanying drawings in which like letters indicate corresponding parts in each of the views, Figure 1 is a side, and Fig 2 a front, elevation of the improved caster. Fig. 3 is a perspective View of a roller and its carrier, and Fig. 4 is a detail front elevation of the body-frame devoid of the said roller and carrier.

In said drawings, a indicates the body frame or plate, comprising an angular L shaped piece of sheet metal, the arms a a of which are at the center and toward and at the angle formed by said arms, forced outwardly, as shown in Figs. 2 and 4, the convexity formed by forcing the metal giving additional strength to the plate. The lower arm at the center of the downwardly-extending convexity is perforated or open to receive the roller-carrier b. The metal forced out from the perforation or opening is employed in part in forming depending strengthening-ears c c, said ears being cut out from the body metal and being bent downand lying at the opposite sides of said opening, as shown in Figs. 1 and 2. Said ears 0 o extend over the ends of the pivotal pin d, and thus prevent the latter from moving endwise out of operative relation to the roller.

The roller-carrier h consists of a piece, preferably of sheet metal, having ears 6 6 cut Serial No. 582,884. (No model.)

out of and bent down from its opposite sides, as clearly shown in Fig. 3. These ears e e coincide with the ears 0 a lying in said opening and fit closely against the inner sides of the latter, strengthening them so that they are capable of resisting greatly-increased lateral pressure of the roller.

The roller-carrier b has arms e, adapted to rest upon the upper side of the arm a of the frame a, and serve as stops to prevent the carrier from passing through the opening of said arm a. After the carrier with the pivotal pin d and roller f are in proper relation within the frame Ct, the pin d, having bearings in the ears 6 e, and projecting outwardly beyond the same at opposite ends, and the roller being arranged on said pin 61 between said ears, the outer strengthening-ears c c are forced inward by means of a suitable press against the projecting ends of the pins, upsetting the said ends as said ears are pressed against the ears 6 e of the roller-carrier, so that they bear hard against the opposite ends of the pivotal pin cl and upon the ears e e, holding said pin firmly and securely in place, bracing or supporting said cars, so that they will not bend or break under any ordinary pressure, and also holding the carrier b to the frame a, allas will be clearly understood by one skilled in the art.

Having thus described the invention, what I claim as new is-- The improved trunk caster herein described, comprising a frame open to receive a roller-carrier and having strengtheningears formed at the sides of said opening, a roller-carrier having ears 6, a pin 61, held in said ears 6, and a roller on said pin, the strengthening-ears extending down to the line of the pin and engaging the opposite ends of the same to prevent lateral displacement, and strengthening said ears 0, said parts being combined, substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 27th day of February, 1896.

MORITZ ISIDOR.
