G. R. SALBERG ROLLER SKATE Filed June 21. 1926 Patented Aug. 23, 1927. y

GUSTAVE R. SALBERG, OF CHICAGO, ILL BEARING SKATE COMPANY, OF-CHICAGO,`

ROLLER.

Application led June 21,

My invention relates'. to roller skate construction, and its principal object is to provide certain improvements whereby the strength of the `skate is increased and the manufacture and assembly of its parts s1m\ plied and the cost thereof reduced. These lmprvements consist in certain changes in construction of the hangers, so-called, for connectin the wheel or roller trucks with the footlate, and the provision of alongitudinal brace for strengthening and rigiditying the foot-plate and the skate structure as `a whole. A further object is to provide means whereby, without sacrifice of strength or rigidity, the skate may be made extensible telit shoes of different sizes. This feature of the invention' is o tional. 't The other mentioned features are intended to be used conjointly but would have some utility if 2 0 used separately, and hence 'will be .clalmed both in combination with eachother and by themselves.

The invention is illustrated in certam preferred embodiments in the accompanying drawing. As further modifications in structural details might be made without departure from th'e'principles of the invention, it is the intention to cover by patent, all struc# tural variations within the scope of the appended claims.

Referring to the drawing,

Fig. 1 is a longitudinal sectional view of a roller skate embodying. certain of the improvements of my invention.

Fig. 2 is an inverted plan view, in sectlon,

Fig. 3 is a view in perspective of one of themembers ofthe hanger used at each end of the skate, .and

Fig. 4-is a view similar to Fig. 2, but on .an enlarged scale showing a modiication embodying the a ove mentioned optional features of the invention.

Referring rst to Figs. 1, 2 vand 3, 10 desi I ates the foot-plate of the skate formed at t e back with a heel rest 11,provided with slots 12 for a fastening strap. The forward end of the foot-plate is provided with suitable toe clamps 13. which are of familiar construction and need not be described as my present invention is not concerned with these devices.-

The foot-plate is carried on front and back roller trucks, each provided, preferably,

* with a pair of rollers 14, of anysuitable con-4 '1,640,134 UNITED STATES PATENT OFI-fica..

struction and turning in suitable bearings, not shown in detail, interposed between the rollers and lthe ax'les A15, 16.

The rear truck consistsof a tubular member 17 enclosing the axle 15 and provided with a cushion seat 18 and an upwardly and rearwardly extending strut 19, the extremity of which extends, without attachment, into a pocket 20 on the under side of the footplate. On the cushion seat 18 is a resilient,

preferably rubber, cushion 21 provided with a metal cap 22. The heel portion of the footplate 10 is formed on its upper, surface with a recess 23. Preferably, the foot-plate is made of sheet metal and the recess is pro vided by `forming the plate'with a rounded offset 24. The offset is perforated for a hanger member 25, which is tubular in form and interiorly threaded, and provided with a head 26 the upper surface of which is preferably fiat and the under surface curved or rounded to lit the rounded surface of the recess` 23, .the head lying entirely within the recess. A threaded bolt 27 extends through the cushion seat 18 of the truck through the cushion 21 and its cap 22 and engages the in- -`terior threads of the hanger member 25.

The -forward truckis of similar construction and similarly connected with the footf late. It consists of a tubular member 28 aving an upwardly and forwardly extending brace 29 which enters apocket 30 on the under sidev of the foot-plate, the truck being provided with a cushion seat 30a supporting a cushion 31 with its metal cap 32,'and the hangerconsisting of the tubular member 33 and'bolt 34, the tubular member being provided with a head 35 which lies in the recess 36 formed in the foot-plate.

Extending under the middle portion of the foot-plate is a metal brace 38 consisting, in this embodiment of the invention. of a single bar or strip of metal` the width of which is considerably greater than its thickness, arranged edgewise against the lunder side of the foot plate and formed at opposite ends with loops or circular bends 39. 40 embracing the tubular portions of the hanger members 25, 33. Lock nuts 37 on the bolts 27, 34 bear against the loops or bends 39, 40 of the brace and hold the brace to the foot-plate.

As the u wardly extending hanger members 19, 29 ave a loose connection with the pockets 20, 30 and resilient cushions are in terposed between the trucks and the hanger members 25, 33. the upper part of the skate has a certain exibility in relation to the trucks. At the same time the attachments between the foot-plate and tiruck are strong reliable and durable and the foot-plate itself is braced and rigidified against bending or breaking. The brace 38 ties the hangers together, besides giving a rigid bridging support for the coupling.

ln Fig. 4 l have shown the `foot-plate as consisting of separate heel and toe sections 41 and 42. 'llhe same hanger construction may be used as illustrated in the preceding ligures. The brace as shown in Fig. 4 is made in two parts, adjustably interlocked for varying the length of the skate. The brace is shown as consisting of a bar of metal 43, the end of which is bent to form a loop 44 extending around the shank or tubular member 33 of the forward hanger. The other member of the brace consists of a return bent bar looped at 45 around the rear hanger member 25, With its two ends 46, 47 riveted together at 48 and spaced apart beyond this place to receive the bar 43. the bars being formed at suitable intervals With perforations 49 for bolts 50 or other suitable fastening devices. By the term foot-plate ll mean to include eit-her a single plate as shown in Figs. l and 2 or a plate made in two sections as shown in Fig. 4.
