.SPECIFICATION fmlmg part of Letters Patent No. 3o2,o1e, dated July 15, 1884.

Application filed March 24, 1884. (No model.)

To `all whom it may concern:

Beit known that we, JAMESS. NEWELL, of Newton, in the county of Middlesex and State of Massachusetts, and HENRIE D.. STONE, of

' of a roller-skate embodying our invention.

Fig. 2 is a plan of the same with the heelstrap removed. Fig. 3 is a central longitudinal section of the same. Fig. 4 is a transverse section on line xix on Figs. 2 and 3. Fig. 5 is atransverse section on line y y on Figs. 2 and 3. Fig. 6 is a central section of the spring receivingsocket detached from the other parts, and showing the bearing for supporting thel axle-carrying stand in elevation.

Figs. 7 and 8 are respectively a plan and ele-v vation of the axlecarrying stand', and Fig. 9 is an end elevation of the toe-clamp-carrying stand detached.

The foot rest or support is made from thin sheet-steel in two parts, which overlap each other, and are adjustably secured together by means of the two bolts co a and nuts a' a', said bolts being each fittedv to a hole, a2, in one of said parts, and passing through and adapted to be freely moved lengthwise of said support in a slot, b, cut in the other part, and extending longitudinally thereof, as shown in Figs. 2and 3'. The partA ofsaid foot-support has formed in its upper surface a rectangular recess, c, of

a depth just equal to' the thickness of thel metal, to receive the forward end of the part A, so that the upper surfaces ofthe two parts, or those portions thereof upon whichthe boot rests, shall be substantially in the same plane. Both of the parts A and A' have formed in their upper surfaces two long and parallel depressions, d d, and corresponding projections upon their under sides, so arranged that the projections on the under side ofthe part Aflt into the depressions in the .upper surface of the part A', and serve to guide'the parts when being adjusted, and aid inpreventing lateral movement of one part upon the other when clamped together, as shown in Fig. 5. The part A has formed in "its upper surface the curved depression c, extending around the heel portion thereof, near its outer edge,and a corresponding projection on its under side, and the part A' has a similar depression, f, around its Outer edge,with a corresponding projection upon its under side, these depressions and projections being formed by bending or embossing the metal in suitable dies, for the purpose of stiffening the foot-support, and thus render- 'ing it practical 'to use thinner metal therefor yand make a lighter skate. l

vB B are two sockets made in the form of anged rings, the axes of which are oblique to their anged upper ends, and have formed in the front and rear sides of their inner surfaces the bearings g g, open at their upper sides, as shown in Fig. 6, said bearings being designed to receive the trunnions It hof the axle-carrying stand C. (Shown in Figs. 7 and 8.) The sockets B B each have east thereon and projecting upward therefrom a series of pins, c' i', which pass through holes formed in the plate A or A', and are headed down thereon, for the purpose of securing said rings firmly to the plates A and A', by which meansa great saving in labor is made over riveting said rings to said plates by the use of ordinary rivets, inasmuch as the number of holes to be drilled or punched is reduced one-half by having the rivets formed upon and integral with the rings B B. D D are pieces of rubber placed within the sockets B B, and between the upper ends of theV axleLearrying stands C C and the underv side of the platesA and A', to serve as springs and render the skate yielding in a well-known manner. By compressing the rubbers DD to a greater extent than in their ordinary-use the trunnions of the stand O C may be removedv from the bearings g g, and then by turning said stand partially around they may be removed for the purpose of renewing the rubber when it becomes worn. As, however, it re- IOO quires a very heavy pressure to remove the stands C C in this way, other means of access to the rubber springs are provided by cutting a circular opening, E, in each of the plates A and A, directly over the springs D D, with two rectangular notches, j, cnt in opposite sides of each of said openings, said openings being each closed again by a plate of steel, F, cut to the same shape as the opening, and having its projecting ears k offset an amount equal to the thickness of the metal, and after passing said ears through the notches j j the plate F is moved about a vertical axis about a quarter of a revolution to pass said ears k under the plate A or A by means of a forked wrench placed in the holes Z Z in said plate, as shown in Fig. 2. To strengthen the plates F, asupplementary plate, on, having parallel sides, is placed beneath each of said plates F, and eX- tends nnder the plate A or A', as shown in dotted lines in Fig. 2 and in section in Fig. 4.

G G are two sliding toe-clamping jaws 'fitted to dovetailed bearings in the stand H, and arranged to be adjusted toward or from each other by means of the screw-spindle I, provided with right and left hand screw-threads, which work in corresponding female threads, formed in the ears G of said jaws, said screwspindle being prevented from moving endwise by the yforked ear H', projecting downward from the stand H, and engaging a circumferential grooove in said screw-spindle in a wellhuown manner. The stand H has cast therewith and projecting upward therefrom a series of pins or rivets, n n, which pass through holes drilled or punched in the plate A', and are riveted down thereon to secure said stand and plate iirmly together.

J J are laxles set in the supports or stands C C, and having mounted thereon the trucks L L in any well-known manner.

XVe are aware that roller-skates having extensible foot supports or plates have been made and used, and therefore we do not claim, broadly, an extensible or adjustable foot-support.

W'hat we claim as new, and desire to secure by Letters Patent of the United States, is-

1. A roller-skate having a foot-support made in two parts of thin sheet metal, arranged to overlap each other and to be adjusted to vary the length of the skate, and having their sur' faces embossed or struck up to form depressions upon one side, and corresponding proj eotions upon the other side extending around the outer portion of said foot-support, substan- 5 5 tially as described.

2. The plates A and A', each provided with the bolt-hole a2, the slot b, and the two parallel depressions d d, in combination with the bolts a a and nuts a a', all arranged and adapt- 6o ed to operate substantially as and for the purposes described.

3. The combination, in a roller-skate, of the plate A, provided with the bolt-hole a? and the slot I1, the plate A', provided with the rectan- 65 gularrecess c, the bolt-hole a2, and slot b, and the bolts a a and nuts a a', all arranged and adapted to operate substantially as described.

4. The combination, in a roller-skate, of a footsupport made of sheet metal, the ringsocket B, provided with the open bearings g g, and the axle-carrying stand C, provided with the trunnions h h, integral therewith, substantially as described.

5. The combination, in a roller-skate, of a foot-support made of sheet metal, and perforated with a series of holes, and a springinclosing and axle-stand-carrying socket provid ed with a series of pins or rivets to fit said holes, and formed integral with said socket, substantially as and for the purposes described.

6. rlhe combination, in a roller-skate, of a foot-support made of sheet metal, and having formed therein the opening E j, the ring-socket B, the axle-supporting stand C, the rubber spring D, and the plate F, provided with the ears k, and adapted to be removably secured inthe opening E j, substantially as described. i i i 7. The combination of a sheet-metal foot support, with the toe-clamp stand H secured thereto by means of rivets u n, formed thereon and integral therewith, substantially as described.

8. The combination, in a roller-skate, of the plates A and A', each provided with the two longitudinal and parallel depressions d d, and one or more bolts for clamping said plates together in variable positions, substantially as described.

In testimony whereof we have signed our IOO names to this speciiication, in the presence of two subscribing Witnesses, on this 21st day of March, A. D. 1884.
