SKATE.
SPECIFICATION forming part of Letters Patent No. 585,866, dated July 6, 1897. Application lecl October 29, 1896. Serial No. 610,518. (No model.)
,To all whom it may concern:
Beit known that I, JOSEPH R. HARRISON, a citizen of the United States of America, residing at Chicopee, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Skates, of which the following, taken in oonnection with the accompanying drawings, is a specication.
This invention relates to improvements in that class of skates in which the movable heelclamp member and the paired sole-clampsare united by a cam-shaped leverpivotally connected to the one clamp and by a link pivotally connected to both the lever and the other clamp, whereby the swinging of the lever in one direction distends the sole-clamps sidewise and the heel-clamp endwise, and the swinging of the lever in the opposite direction contracts the clamp members.
A peculiarity in the clamp mechanism of the class aformentioned consists in the double fulcrum as constituted by the pivot connecting the lever to the link, and the pivot connecting the pivot which in substance connects the lever to one of the clamps so that both sets of clamps may be brought to their proper bind on the sole and heel, because, for instance, after the lever has swung for its center of motion on the pivot, which connects it with the link which is pivoted to the sole-clamp, and has drawn the heel-clamp to bearing on the heel, the fulcrum is then changed to the pivot connecting lever with heel-clamp, whereupon the aforesaid lever and link uniting pivot as the lever is further swung derives movement to operate through the link the sole-clamps.
The present invention relates to an improvedadjustable connection between the lever and one of the clamps whereby the maximum distention of both sets of clamps may be varied at pleasure to adapt the skate to boots or shoes having soles of varying widths and heels of various lengths; and the invention consists in constructions and combinations of parts, all substantially as will hereinafter fully appear, and be set forth in the claims.
Reference is to be had to the accompanying drawings, forming part of this specification, in Which-h Figure l is a side elevation of a skate having my present improvements applied thereon, and Fig. 2 is a plan view of the same. Fig. 3 is a sectional view through the novel parts as taken on the line 3 3, Fig. 2. Fig. 4. is a perspective view of parts in detailnamely, of a yportionof the heel-clamp, the adjustable interlocking connection block or plate, and the connecting-bolt.
Similar letters of reference indicate corre sponding parts in all of the views.
In the drawings, A represents the foot-plate of the skate, and B the heel-plate, having at its forward end the xed heehclamp member ct;
O C are the sole-clamps, having the studand-slot guiding engagement with the soleplate at b b, and at their rear ends pivotally united, as shown at c, one to the other and both with the link D, which is rearwardly eX- tended from its place of connection with the sole-clamps- G represents the operating-lever.
The longitudinally-movable and suitablyguided heel-clamp members d d are formed iintegrally with the forwardly-extended heelclamp body or bar-shaped portion H, which is provided with the longitudinal slot f at its forward end portion, which slotted portion is also on its under side provided with the series of teeth or serrations g. lV ith this sera rated portion of the heel-clamp the block or plate J has, by the serrations t' provided on its top,an adjustable and interlocking engagement.
The iiat lever G carries the standing bolt m, the base thereof being upset, as shown at m2, and loosely seated in a countersunk opening therefor within the under side of the lever, this construction permitting the lever to swing on and relatively to the bolt. The bolt for a portion of its height' has its side or sides squared, as shown at m3, and passes through an aperture in the plate J of corresponding form, so that there may be no rotary motion of the bolt and plate, the one relative to the other. The upper end portion of the bolt is of somewhat decreased diameter and screw-threaded, as seen at m4, and projects through and upwardly beyond the slotted portion H of the heel-clamp. The squared or iiattened portion of the bolt does not reach quite to the top of the heel-clamp bar H, whereby the ICO thumb-nut F, which screws on the threaded portion of the bolt, may seat itself firmly against the top of the clamp-bar II, eifectuallyinsuring the connection of the serrated plate J for any desired length of time as one with the clamp-bar.
The lever G has its pivot n, which connects it with the link, a short distance to one side of the bolt which constitutes the pivot between the lever and block-and-heel clamp, which block and clamp to all intents and purposes are as one, except at such times as itis dep thereon the thumb-nut which is adapted to sired to alter the degree of distention of the clamps, when of course it is understood by loosening the thumb-nut sufficiently on the bolt, allowing the block to separate from the clamp-bar as much as the distance of the otally connected thereto, the operating-lever, -G, provided with a pivot N which passes through the rear end of the link; and the bolt M, by which the parts are connected, combined with a separate bolt J serrated upon i its upper face, and the heel-clamp provided depth of the serrations, the block maybe slid forwardly or rearwardly relatively to the clamp-bar or the clamp-bar to it. By adjustably confining the block and bolt rearwardly relatively to the heel-clamp provides for a lessened distention of both the sets of clamps, while the forward setting and coniinement provides for an increased limit of the distention.
I claim- 1. The combination,'in a skat'e of the character described, with the sole-clamps and the link pivotally connected thereto, of the heelclamp longitudinally slotted, the block having an adjustable interlocking engagement with the heel-clamp, the lever pivotally connected to said link, and a bolt having an engagment with the lever, passed through the block and the slot inthe heel-clamp and receiving the binding-nut, substantially as and for the purpose set forth.
2. Ina skate of the character described, the combination with the sole-clamps and the link pivotally connected thereto, of the heelelanip having on its under side the series of serrations, the block having on its upper side a seriesv of serrations and having a squared opening through it, the lever pivotally connected to said link, and the bolt having on l its lower end an enlargement loosely seated in a countersink therefor in the lever, havu n ing a portion thereof extending upwardly l through the slot squared, whereby the block may not rotate on the bolt, and said bolt having its upper extremity threaded, receiving seat itself upon the upper side of the slotted heel-clamp, all substantially as and for the 3 purposes set forth.
3. In a skate the sole-clamps, the link pivat its front end with a slot F, and having its under surface serrated so as to engage with the block and a thumb-nut which is applied to the upper end of the bolt for clamping the parts together; the block J being stationary on the bolt whilethe heel-clamp is adjusted back and forth in relation to the block so as to regulate the distance the clamp shall be moved substantially as shown.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 26th day of September, A. D. 1896.
JOSEPH R. HARRISON.
