ROLLER-SKATE.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed March 12, 1906. Serial No. 305,628.

T0 all whom t may concer-n.-

MBe it known that I, GEORGE C. PLUMMER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvernent in Roller-Skates, of which the following is a specification.

My object is to provide a foot-plate for roller-skates which shall meet all of the requirements of its use, be strong and light, and inexpensive to manufacture. I accomplish this object by forming the foot-plate of sheet metal cut and stamped by die and press to give it the proper form to provide a seat conforming to the foot of the user and brackets for the journaling and support of the roller mechanism or action Referring to the accompanying drawings,

Figure 1 is a plan view showing a sheet-metal I blank of suitable form for my purpose, indicating by full lines the lines on which the metal is to be cut and by dotted lines those lines on which the metal is to be bent to form the brackets, ears, clampingguides, and heel-socket. Fig. 2 is a view of the footplate in section, indicating by full lines the preferred shape into which the blank is to be stamped and a brace for giving added rigidity to the center brackets; and Fig. 3, a broken sectional view taken on the line 3 in Fig. 1 and viewed in the direction of the arrow.

A is a sheet-metal blank which may be cut from any suitable sheet metal, preferably steel, and having a toe portion A and a heel portion A2. Two pairs of opposed tongues a a are cut in the metal of the toe portion, one pair on each side of its longitudinal center, and bent downwardly and inwardly on the dotted lines a a to the position shown in Fig. 3 to form guidewaysfor the usual ladjustable toe-clamping devices. (Not shown.) Ears b b are cut in the metal of the toe portionbetween the pairs of tongues a. and are bent downwardly on the dotted line b to the position indicated in Fig. 2 for engaging the usual right and left4 hand screw which operates the toe-clamps. (Not shown.) Apertured opposed tongues c d are cut in the metal of the toe portion A', the former having formed in it an ap'ertured tongue c bent on the dotted line c2, preferably at a right angle to the tongue c, the tongues c and d being 'referably bent downwardly on the dotted ines c3 d', respectively, to the substantially parallel inclined positions indicated in Fig. 2. The apertured end of the tongue c is preferably bent on the dotted line c4 at a right angle to the body of the tongue c to cause the aperture thereon to aline with the aperture in the tongue c. The tongues c c and d form brackets for receiving and supporting in a common manner the forward cushioned roller mechanism or action. (Not shown.) Tongues e, e', and f, respectively, are formed in the heel portion of the footplate and are bent, preferably, downwardly on the dotted lines e2, e, e4, and f', res ectively, to the portions shown in Fig. 2 t ese tongues affording brackets for receiving and securing in a common manner to the footplate the rear cushioned roller mechanism or action. (Not shown.)

' Ears g g, similar to the ears b, are cut in the metal intermediate the tongues c and e and are bent downwardly on the dotted line g for clamping a brace h to the under side of the foot-plate. This brace. has flanged a ertured ends h', which bear against t e lower flanged ends of the tongues c and e, the openings in the flanged ends h coinciding with the openings in the tongues. The heel portion A2 flares, as shown in Fig. 1, and is provided with strap-receiving slots i, the metal being bent upwardly4 on the curved dotted line i to form a heel-socket A3.

The foot-plate blank (illustrated and described as bent into the shape shown in Fig. 2) is adapted for receiving and securing one yform of roller mechanism or action. My invention, however, is not limited to a footplate of the precise form illustrated, as the tongues forming the brackets may be bent `to other angles to adapt them to receive other forms of roller mechanism or action.

What I claim as new, and desire to secure by Letters Patent, is-

1. A sheet-metal roller-'skate foot-plate having tongues cut between its edges and bent downwardly and tongues bent from IOO said first-named tongues et angles thereto to the inclined shaft of the skate-roller mechanform bearings for the inclined shaft of the skate-roller mechanism.

2. A sheet-metal roller-skate foot-plate comprising, in combination, tongues out between the edges of the late and bent down- Wardly, tongues bent om said first-named tongues at angles thereto to formbearings for ism, and an arched brace secured between its 1o ends to the under side of the foot-plate and at its ends to the bearing-tongues.
