Specification of Letters Eatent. Application filed August 7, 1912.

on itself in groove 4% in the following not: A rounded die is provided to receive the end piece. 11 and the tubular portion 10 is then inserted within the hole of the die until the end strikes the inclined wall 15. The sheet metal tubing underheavy pressure will seek the line of least resistance and coils inwardly upon itself along the wall 15 and as it passes inwardly necessarily wedges against the walls of the groove i l thereby firmly holding the tubular end within the groove 14 and giving a smooth outer surface at the joint between the parts which can not mutilate or mar the books. The portion 17 of the end 11 within the tubing 10 is diminished around its periphery the t. ness of the tube 10 so as to make a sine :n exterior for the joint.

lVe claim as new A. metal roller of the type set forth, con sisting of a hollow tube having suhstantially right angular inwardly curled ends of substantially tl-shape in cross section, and pair of end members for the respective tube ends, said end members having annular grooves of suthoient depth to receive said til-shaped ends, the outer Walls of which grooves are directed inwardly and extend toward the outer ends of said end members to provide angular abui'ments against which the outer legs of the lJ-shaped ends of the tube. engage. the opposite walls formed by said grooves also l irovidiug alnitments which engage with the inner legs of the ti -shaped. ends, and act to wedge said legs in said grooves, the free extremities of the inner legs of the Ushaped ends terminating at substantially the. inner surface, of the tube, the periphery of the end members beyond, the grooves being substantially in alinement with the tube periphery whereby to provide locates.

Patented Serial No. 7136,8 16.

1 '0 all whom it may concern Be 1t known that we, VVILLIAJI W. Warsozv and JOHN G. CARLSON, citizens of the town, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Metallic Rollers, of which the following, taken in connection with the accompanying drawing, is a specification.

The invention relates to sheet metal rollers for shelving and particularly for book shelves; and the object of the improvement is to provide a simple and exterior-1y smooth construction having strength, lightness and stability, so that they will roll easily when heavy books are passed over them and will not injure the books; and the invention consists in the construction and combination of the parts as shown in this specification and the accompanying drawings and pointed out in the claim. i

In the drawings, Figure 1, is a side elevation of the improved roller. Fig. 2 is a lengthwise sectional View of the improved roller showing the manner of attaching the sheet metal central tubular portion to the unattached ends, as shown attached in Fig. 2 and-Fig. 4 is a side elevation of said end, showing the annular groove therein. Fig. 5 is an end elevation of one of the rolls.

Like numerals of reference refer to corresponding parts in the several views.

The numeral 10 designates the sheet metal tubular central portion of the roller, which may be a seamless or a brazed tube or may be a strip of sheet metal bent intubular form. The seamless or brazed tube is preferred.

The numeral 11 designates the end piece to which the tubular portion 10 is attached. The end pieces 11 are preferably made of metal and have their ends 12 slightly rounded and a central pivot or journal 13. A groove 14 is provided around the outer periphery of the end piece 11, care being taken that the wall 15 be at an inwardangle toward the ends of the roller. The bottom of the groove 14 is rounded, as shown in Figs. 2, 3, and 4, to receive the tubular end of the central portion 10 which is turned inwardly ll itnesses H. A. Snnnnnao, Aa'rnnn 0. Motion.
