THOMAS SPACIE, OF CHICAGO, ILLINOIS.

ROLLER-SKATE.

Specification of Letters Patent.

Application filed August 22,

To all whom it "may concern:

lie it known that I, THOMAS SPAGIE, a citizen of the United States, and a resident of thicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Roller-Skates, of which the following is a specification.

This invention relates to skate rollers.

The primary object of the invention is to provide a skate roller made. wholly or principally of sheet metal, preferably mild sheet steel, which will be simple in construction, strong, durable and relatively light in weight; which can be n'ianufactured at a relatively small cost; and which will be neat and ornamental in appearance. To effect these ends a. skate roller of my invention comprises the various features and details of construction. hereinafter described and claimed.

1n the accompanying drawing, in which my invention is fully illustrated, Figure 1 is a side view of my improved skate wheel. Fig. 2 is a sectional view thereof on the line 22 of Fig. 1. Fig. 8 is a sectional view, similar to Fig. 2, of a skate roller embodying my invention in modified form.

The body portion of my improved skate roller, designated, a whole, by A, consists of two substantially symmetrical sections 1 and 2, stamped or pressed from suitable sheet metal of a thickness to afford requisite strength, say one sixteenth of an inch.

Each of the sections 1 and 2 comprises a web consisting of a central fiat portion 3 and an inclined portion 4 to which the tread of the wheel is secured. The central flat portions 3 of said webs are rovided with axial openings 5 through which the axle of the wheel is adapted to pass freely and sur rounding said openings 5 are flanges 6 formed, as shown, by the metal stamped out in forming said openings 5.

The tread portion 7 of the roller is formed integral with one of the roller sections 1 or 2, as shown, with the section 1, by stamping or pressing the outer portion of the blank from which said section is formed into proper shape.

To form the body portion A of the roller, the sections 1 and 2 are placed to ether with their flat portions 8 in contact and with the inclined portions 4 thereof diverging outwardly. The tread portion 7 of the section 1 is made of such width that when the sections 1 and 2 are assembled to form the Patented Nov. 9, 1909.

1908. Serial No. 449,769.

roller body A, the outer edge of said tread portion 7 will project beyond the outer face of the section 2 and the said sections 1 and L are secured together to form a rigid structin-e by turning the edge of the tread portion T of the section 1 over the outer edge of the section 2, as clearly shown at 8.

In order to make the roller A as light as possible, holes or openings 9 are preferably formed in the webs thereof, preferably in the inclined portions l, said holes or openings being made as large as consistent with requisite strength. Said holes or openings 9 will also impart an ornamental finish to the wheel.

The body portion A of the roller is revolnbly mounted on the axle 10 by means of ball bearings, consisting, as shown in Fig. 2, of antifriction balls 11, running in suitable ball races formed in cones l2 and

cups

13 and 14. The cones 12 are preferably made of tool steel, hardened, and are mounted directly on the body portion A of the roller concentric therewith by means of axial holes or openings therethrough adapted to engage the flanges 6 on the )ody portion of the roller, being preferably tightly fitted thereto so as to be retained thereon by frictional engagement therewith. The inner sides of the cones 12 are designed and adapted to bear against the flat portions 3 of the webs of the roller.

The ball cups 13 and 14: are mounted directly upon the axle 10 concentric therewith, being provided with axial openings closely fitted thereto. To provide bearings of desired length for the said cups on said axle, they are preferably provided with flanges 15, which surround the holes or openings there in which receive said axle. Said flanges are preferably formed of the metal stamped or pressed out in forming the axial openings in said cups. The inner cup 13 bears against the skate truck 16 or a washer interposed between said cap and skate truck and, preferably engages the same with a close sliding fit only. If desired, however, my invention contemplates screwtl1reading said cap 13 t0 the axle. This construction is objectionable, however, for the reason that it unnecessarily weakens the axle. The outer cup 14 is in screw-threaded en agement with the axle 10 and is adapted tome secured in any desired adjustment thereon by means of a nut 17 threaded to said axle outside of said cup 1 1,-

a washer 18 secured to the axle 10 against rotation, being preferably inserted between said cup 11 and the nut 17. As shown, said washer is secured against rotation by correspondingly tlattening a side of the axle 1t) and of the hole or opening through said washer, as shown at it), Fig. l.

Due to the arrangement shown and described, in which the cones of the ball bearings are mounted on the wheel inside of the ball cups, said ball cups will prevent access of dirt and dust to the bearings, thus dispcnsing with separate dust caps and correspondingly simplifying and chcapening the construction.

1n Fig. 3 of the drawing, I have illustrated a modified form of my lll'lPlUVCtl roller, said modification relating particularly to the construction of the tread thereof and to the cones of the ball bearings. Iteferring now to said Fig. 3, A designates the body portion of the roller, 1 and 2 the sections thereof, 10 the axle, 13 and 14: the inner and outer ball cups, respectively, 16 the skate truck and 17 and 18, respectively, the lock nut and washer for securing the ball cup 14 upon the axle 10, all of which are substantially identical in construction, function and operation with the corresponding parts of the roller shown in Figs. 1 and Q. As regards the tread portion of the roller, said modification consists in forming tread flanges 7 and T on the sections 1 and 2 respectively, of the roller, the tread flange 7 being the same as the tread flange 7, Figs. 1 and 2, and the tread flange 7 being sufl'iciently smaller in diameter than the flange 7 to fit snugly inside thereof and being of such width that its edge which extends beneath the flange T will bear against the in nor side of the web portion of the section 1 of the roller when assembled. The sections 1 and 2 are secured together to form a rigid structure by turning the outer edge of the tread flange? over the angular edge of the section 2 as shown at 8 iVhile said modified form of roller will obviously be stronger than the roller shown in Figs. 1 and 2, particularly to withstand the stamping or pressing operation in turning over the edge 8 in securin the sections 1 and 2 together, it will weigh slightly more. Furthermore it is believed that said additional strength is superfluous and that the form of roller shown in Figs. 1 and 2 is suflicicntly strong for all practical purposes.

As regards the cones of the ball bearings, the modification shown in Fig. 3 consists in forming said cones integral with the sections 1 and 2, which can be conveniently efiected by making the flanges which surround the openings 5 in the sections 1 and 2 of said roller of proper shape and size to form said cones as shown at 6 I aim 1.
