UNITE-D srArfEs 1,970,612 Y RoLnEit SKATE James Edward Marshall, NewHaven, Conn., as-

signor to Winchester Repeating Arms Company, New Haven, C0nn.,..a corporation of Maryland 'Application June 28,` 1933, SerialfNm 677,962 4. v Claims.. (C1.v 20s-473) This invention relates to roller skates and more particularly to a,roller skate havingimproved adjusting meansl to t the skate to the shoe :of

the skater.

In carrying out my invention I provide a skate comprising a heel plate, and toe plate having a girder formed integrally with one of said plates, preferably the toe plate. The girder is provided with an elongated slot adopted to receive a b01t carried by the heel plate to adjust the size of the skate. I further provide side flanges on the girder which may extend throughouta portion of the toe plate to stiffen it and produce a more rigid construction.

The girder flanges are provided with longitudinal ribs or grooves vto increase the strength 1of the skate. By forming ribs on the ilanges itis possible to employ lighter material in the construction of .the skate and still obtain a rugged construction. 1 f

In one form of the invention, the rear- -truck hangers are provided with inwardly extending lugs suitably spaced from the heel plate toform ledges on whichthe girder flanges rest. This provides a more rigid construction than would be obtained if these ledges were omitted.- In another formof the inventionthe side walls of'thetruck hangers are provided with ribs which are received in the longitudinal grooves of the girdenflanges and form guides for the girder.

A further feature of the invention consists in providing indentations in the truck hangers whereby a more rigid construction is obtained and whereby the elastic cushion generally employed in skate constructions is rigidly clamped in the truck hanger.

In the accompanying drawing I have shown several forms of the invention. In the drawing,

Fig. 1 is a side elevation of one form of skate, parts being shown in section;

Fig. 2 is a plan view thereof;

Fig. 3 is a transverse, vertical, sectional view on line 3-3 of Fig. 1;

Fig. 4 is a detailed view of the rear truck hanger; and,

Fig, 5 is a transverse, vertical, sectional view (similar to Fig. 3) showing a modified form of the invention.

Referring to the drawing, the reference numeral 1 designates a toe plate and 2 a heel plate o a skate. A girder 3 is formed integrally with one of the foot plates, preferably being formed integrally with the toe plate as shown. This girder is provided with a longitudinal slot 4.

-A bolt 5 is mounted in an opening in the heel plate and" is adapted to pass through the slot 4. A nut 6 is mounted on .the bolt to permit the plates to be` retained in any desired adjusted position.'1 Y. '.TheA girder is provided with downwardly exoo tending side flanges '7 which may be formed integrally with marginal anges. 8 extending throughout a portion of the toe plate. The anges-7 are provided with longitudinal grooves 9 oni their outer sides forming ribs on the inner 65 sideA of these flanges. The ylongitudinal Vgrooves 9 materially. strengthen the girder and give support-'to the skater at a point where the skate is normally subjected to. considerable strain. By providing. these grooves and strengthening the 7p girder construction, I find that lighter material may be employed in the construction of the skate and at `the same time-obtain sufcient ruggedness for usual skate use. g

A truckhanger is arranged on each of the 75, footpiecesof -theskate 'I'hese truckhangers are essentially of the same construction andthe same reference numerals' will, therefore, be ern-.- ployed to designate the various parts. Each of the truck hangersconsistsof apair of parallel side 80. plates 1 0. -They are secured to the foot pieces by integral rivet lugs 11 carried on the vupper surfacesofAv thevside pieces and adapted to pass through slots in the foot pieces. After the rivet lugs al'ein position in the slots they are headed 85 over in the usual manner to secure the truck hangers in place. The side pieces are connected by a cross member 12 which is preferably arranged at an incline to the plane of the foot pieces and which is provided with front and rear flanges 13 and 14. The truck hanger cooperates with a cradle member or axle support 15 which is of substantially the same size and arranged parallel thereto. This member is also provided with front and rear flanges 16 and 17 adapted to be 95 arranged adjacent the lianges 13 and 14 of the truck hanger. A rubber cushion member 18 is arranged in the space formed by the truck hanger and supporting member 15 and a cotter pin 19 is passed through the rubber pad and through aligned openings in the ilanges 13, 14, 15 and 16. The supporting member 15 carries a sleeve 20 adapted to receive an axle 21 on which the rolls 22 are mounted.

In the form of the invention shown in Figs. 1 to 4 of the drawing the upper portions of the side plates are slightly oiset as shown at 23 and are slightly spaced from the flanges of the girder 3. Beneath this offset portion the side plates are spaced from each other a distance substantially equal to the width of the girder as lil@ shown in Fig. 3 of the drawing. 'Ihe rear side plates are provided With lugs 24 struck inwardly from the body of the material forming ledges upon which the side flanges '7 of the girder are adapted to rest. These ledges are spaced from the top of the side plate a distance equal to the Width of the ilange 7 so thatiwith theglower edge of the ilange resting on theledge thegirder is retained in close contact with the bottom of the heel plate.

In the form of the invention shown in Fig. 5Y of the drawing the side plates 10 are not provided with the offset portions 23 but extend upwardly' to the heel plate 2 at a distance from each other substantially equal to the `t'vidth of girder 3. They are provided with longitudinally extending grooves 25 on their outer faces adapted to form longitudinally extending ribs on theirinner faces, which ribs are received in the grooves 9 of the flanges of the girder. It will be apparent that this construction provides a guide for thel girder and vadds to the rigidity of the skate.

To'further add to the rigidity of the skate-and permit the use of lighter material in the constrwrtion of the skate without sacriilcing necessary strength, I provide indentations 26 at the front and rear edges of the cross piece 12 'which connects the side pieces 10 of. `the truck hanger. Similar indentations may-be provided at the junction of the sidewalls 10 and the cross piece 12. These indentations, `'wl'iieh arepreferably formed at the-pointwherethe end-ilangeslS anddd are joined to the body portion of :the cross piece, not only add to the strength of the truck henger but also more rigidly-clamp the cushioning pad imposition .lhetoe piece is .providediwith the usual clamps 27 mounted onasuitablebracket on the bottom of the toe piece and adapted-tothe adjusted by a vkthreaded rodv28l inthe usual manner. ALike-- wise, .the heel piece-'is provided with' theiusual anges 29 to whichra skate strap Knot-shown) 'may be attached in any V:suitable manner,- -The toe plate may also be provided with ribs 30 formed in the metal for the purposeV of strengthening this member and thereby permit theA` 'use of lighter material. -1

It will be apparent from the 'foregoing de-` scription that l have provided a roller skate which is made of a relatively small number of parts and which is of simple construction and therefore relatively inexpensive to manufacture. At the same time the construction provides unusual ruggedness and therefore permits the use of light material in the manufacture of the skate.
