ROLL FOR ROLLER-SKATES.

Specification of Letters'latent.

Patented Mar. 26. 1912.

Application filed July 18, 1911. Serial No. 839,128.

To all whom it may concern:

Be it known that I, Orrs W. EVERETT, a citizen of the United States, residing at Vorcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Rolls for Roller-Skates, of which the following is a specification.

- My invention relates to a roll or wheel and to a metal roll or wheel particularly designed for use on roller skates.

ceive one set of balls, which are contained within two .ball cases or cups. The ball cases or cups are made separate from the sides of the roll. One of the'ball cases has an annular lip or flange on its edge, extending at substantially right angles to the body portion, to extendover the annular lip or flange on the other ball case, and hold said case in position. One of the sides of the roll has the periphery or tread of the roll integral therewith. The other side extends within said periphery or tread. The two ball cases or cups are held and secured in position between the two sides of the'roll or wheel, as will be hereinafter fully described.

Referring to the drawing :-Figure 1 is a side view of a roll of my improved construction. Fig. 2 is a section, on line 2, 2, Fig. 1, looking in the direction of arrow (1, same figure. Fig. 3 is a side view of one of the sides of the roll having the tread thereon. Fig. 4 is a section, on line 4, 4, Fig. 3, looking in the direction of arrow b, same fi ure.

Fig. 5 is aside view of the other side 0 the roll. Fig. 6 is a section, on line 6, 6, Fig. 5, looking in the direction of arrow 0, same figure. Fig. 7 is a side view of one of the ball cases or cups. Fig. 8 is a section, on line 8, -8, F ig.7, looking in the direction of arrow (1, same figure. Fig. 9 is a side view of the other ball case or cup, and Fig. 10 is a -section,'on line 10, 10, Fig. 9, looking in the direction of arrow e, same figure.

In the accompanyin drawing, 1 is the central shaft or stud o the roll, preferably of metal, and having a central longitudinal opening 1 therethrough, see Fig. 1, to receive the axle of the roller skate,=not shown.

The stu'd 1 has in this instance one circumferential groove or recess 1", see Fig. 2, in its periphery, to receive in this instance one set of metal balls 2. The set of metal balls 2 extend around the stud 1, in the recess 1", and are retained in position by the two ball cases or cups 3 and 4.

Theball case or cup '3, see Figs. 7 and 8, has a central opening 3 therethr'ough for the stud 1, and on its outer edge has an annular li or flange 3 extending at substantially right angles to the body portion, and made beveled on its edge, as shown in Fig. 8. The other ball case or cup 4 has a central opening 4 therethrough for the stud 1, and the annular lip or flange 4" on the body ortion extends within the lip or flange 3 on the ballcup 3, as shown in Fig. 2. This construction holds the two ball cases or cups 3 and 4 in a fixed relative position, and in, proper alinement, and prevents any side mo tion of one ball cup on the other. It is not necessar to fold or bend the annular lip or flange3 on the ball case 3 over the edge of the annular lip or flange 4 on the ball case 4, to secure them together.

One side 5 of the roll, shown in Figs. 3 and 4,.has the depressed central portion, shown at 5 in Fig. 4, with a central opening therethrough for one of the ball cups, in this instance the ball cup 3. The side 5 has the annular flange or extension 5 thereon extending at right angles to the beveled side portion, see Fig. 4, and forming the tread of the roll. The opposite edge of the treadportion 5" is preferably undercut, as shown at 5" in Fig. 4, and the cut inner edge 5 pressed inwardly, making a recessed portion. The other side 6 of the roll has the central depressed portion, as shown at 6 in Fig; 6, with a central opening there'- through, to receive one of the ball cups or cases, in this instance the ball cup 4. The outer edge of the side 6 is bent at substantially right angles to thedepressed portion, as shown'at-G", Fig. 6, and extends within the tread portion 5 on the side 5, andin the recessed portion 5" in said tread, as shown in Fig. 2.

After the parts have been assembled, as shown in Fig. 2, they'are subject to pressure, which presses the two ball cups or cases 3 and 4 together, and presses the side 6 within the trend 5' on the side 5. The edge of the tread 5" is then turned and spun over the outer edge of the side 5, as shown in Fig. 2, to form a rounded edge on the roll, and ,to secure the side 6 within the tread portion of, the wheel. v

Itwill be understood that the details of construction of my improvements may be varied if desired.

Having' thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A roll, comprising a central shaft or stud, a set of balls extending around-sa-id stu'd, two ball cases or cups for said balls,

held between the depressed portions of the two sides of the roll, and said two sides having depressed portions, and made separate from the ball cups, and extending upon opposite sides of the ball cups, and having the central opening therein on opposite sides of the ball cups, and one of. said sldes having a tread thereon for the roll, and the other side extending within said tread.

2. A roll, comprising two sides, one side having a tread thereon for the roll, and the other side extending within said tread, and

two ball cases or cups held between said sides.- v

3. A roll, comprising two sides, one side having a tread thereon for the roll, and the other side extending within said tread, and two ball cases or cups held between said sides, one of said cases or cups having a cups, and extending upon opposite sides thereof, one of said sides having thereon a tread for the roll, and the other side extending within said tread.
