IMPROVEMENT IN SKATES.

Specification forming part of Letters Patent No. 40,745, dated December 1, 1863; reissue No. 5,705, dated December 23, 1873; application tiled June 23, 1873.

To all whom it may concern:

Be it known that I, JOHN FORBES, of Halifax, in the Province of Nova Scotia, have in- -vented certain new and useful Improvements 'in Skates 5 and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the drawings accompanying this specification and making part ofthe same.

My improvements relate, first, to a central lever, by means of which the heel and sole clamping devices are brought into operation simultaneously; second, to a plate operating the lugs, made adjustable to the central longitudin al lever, to which it is attached, and from which it receives motion, so that the lugs may be adjusted to their proper movement, having reference to the width of the sole which they are required to grasp; third, to the foot-plate,

. pivoted or hinged to the ruimer, and retained in position. at the back of the runner and re.

leased therefrom by a proper mechanism.

In the drawings, which serve to illustrate my improvement, Figure 1 is a plan view of a skate made according to myinvention. Fig. 2 is a vertical sectional view taken in the line a; .r of Fig. l.

Arepresents the runner of the skate; B, the front knee or post, which is firmly secured to the runner, and has the front part of the footplate O attached to its upper end by a hinge or joint, a. In the upper surface of the footplate C, at its front part, there are made grooves, in which lugs I) D are fitted and allowed to slide freely. -These lugs D D are curved upward at their outer end to form clamps or jaws b b, and said lugs have each an oblong slot, c, made longitudinally in it,

and through these slots screws cl pass into the foot-plate, said screws retaining the lugs D D in proper position on the foot-plate, while the oblong slots c c admit of the lugs working asuitable distance in the grooves in the footplate. there are attached two clamps, E E, one at each side. These clamps are formed of upright bars, bent over and inward at their upper ends to form spurs e, to enter the heel of the boot or shoe, the upright bars being at the ends of horizontal projections f, which extend obliquely outward from the foot-plate. The

To the back end of the foot-plate CA foot-plate C has a large oblong` opening made in it, in which a sliding central lever, F, is itted, and to the front end of this lever F there is attached, by screws g g, a plate, G, which' has two oblique slots, h h, in it, the front ends ward, as may be required, for the proper movement in and out of the lugs. To the back part of the lever F there is attached, by screws j j,

a clamp, H, constructed with a toothed or serrated edge, being in a transverse position on the lever F. This clamp may be adjusted farther forward or backward on the lever F by the screws j, which pass through oblon g slots k k. The back part of the lever F rests on the lupper end of a pendant, I, situated at the back end of the foot-plate C, and a screw, l, passes,

through an oblong slot, mf, in the lever F, into the upper end of the pendant. This slot m is of suiiicient length to admit of a requisite degree of longitudinal play or movement of the lever F. J is another lever, the lower end of which is secured, by a pivot, n, tothe runner A. The upper end of this lever J is connected, by a joint, o, to the lever F. At the back end of the runner A, at its upper part, there is a small projection, p, which, when the foot-plate (l is adjusted in proper position, "lits within a vertical slot or recess, q, in the pendantl, and is retained therein and released therefrom by a catch, K, formed of a spring having a slot made in it to admit of said projection p on the runner passing through it. The catch K is secured, by screws, to the rear or outer side of the pendant I.

From the above description, it will be seen that by drawing outward the spring-catch K, so as to disengage the back end of the runner A, the back part of the foot=plate C may be raised, or the back end of the runner A 1owered; and by this movement of either of the aforesaid parts the lever F will be actuated by the connecting-lever J, and the clamp or jaws b b will be forced outward by reason of the pendent pins c* ofthe plates D D working in Trios.

the oblique slots h h. The clamp H will, at the same time, also be moved forward or from the clamps E E. This position of the several parts is shown in dotted lines in Fig. 2.

When the several parts are in this position, the skate is adjusted to the boot or shoe, the heel fitting between the clamps E E and H, and the forward part of the sole tting between the clamps or jaws b b. The back part of the foot-plate is then forced down, or the back part of the runner A drawn upward, which causes the clamps b b to approach each other and grasp the sole, while the clamp H will, at the same time, be forced backward, so that the heel of the boot or shoe will be grasped between the clamps H E E 5 and when the projection p of the ruimer is caught by the catch K, the runner and the foot-plate will be firmly connected and the skate secure] y fastened to the boot or shoe. Y

By adjusting the clamp H farther forward or backward on the lever F, and adjusting the plate G farth er forward or back ward, the clamps b'b H E E maybe made to clamp or grasp boots or shoes of different sizes.

By this invention the skate is secured to the sole of thel boot or shoe at all points simultaneously, and very expeditiously.

I would remark that the sole-plate C may be pivoted to the runner A, either at the front or back end of the former. The arrangement, however, would be substantially the same in either case.

I claim- 1. A central lever, J, substantially as dcscribed, connecting the sole and heel clamps, and through which both are operated simulta neously.

2. .A central lever, arranged to operate substantially as `above described, when combined with a lever which actuates it in connecting and disconnecting the skate.

3. A plate arranged to operate said lugs, when made adjustable to the central lever, substantially as described, so that the lugs may be adjusted to receive a movement in accordance with the width of the sole they are required to grasp.

4. The foot-plate, pivoted or hinged at one end to the runner, and secured and released at the other end by a catch, K, or other suitable fastening mechanism, substantially as described.
