INEERO'VIllVII EINT IN SKATES.

*M I The Schedule referred to in these Letters Patent and making pak-'t of the saine.

To all whom it may conce/rn Be it known that I, Joux LovA'r'r, of Newark, in the county of Essex, and State of New Jersey, have y invented a new and useful Improvement in Clamping and I do herebydeclarc,

Skates to Boots or Slices; lthat the following is a full, clear, andexact description/ thereof, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l represents alongitudnal vertical section, taken through the heel and sole-platcs showing the screw-rod and'movable pieces for adjusting the clamps to the sole of the boot.

FignreQ is a top view o'- theskate, showingthe' four clamps and the movable slotted blocks-iu two positions. Figure 3 is a perspective view of one of the slotted blocks detached from the foot-'stand 'of the skate.

Similar letters of 'reference indicate corresponding parts in the three figures. p

.To enable'those skilled in the art to fully understand my invention, I will proceed to describe its construction and operation.

In-the drawings, A. represents the runner or'skateiron,-of any'` suitable shape, to which are secured, by rivets or screws, two standards, B B, which support the heel and 'sole-plates G C, and to which. thefheel and sole-plates are secured. rlhese plates are of a suf-- ficient length and width to give a firm and steady bearing for the feet.

D D D D are the clamp-bars, which have their edges- 'bevclled down, so that they will Vfit in suitable slots made to receive them in the plates C O', Their ends are turned up, and slightly over, and made sharp, so that they will serve as jaws, which will sink' into the edges ofthe leather sole and heel, and gripe it firmly. The inner ends of these clamping-jaws have pins, c a, shown in dotted lines, g. l, projecting ldown into slots b, in blocks E E, lig. 3.

These blocks are placed under the sole and heelthe same, and are suitably held to these plates between guides, which only allow them to have a longitudinal movement. rlhe grooves l1 are cut into thel faces of blocks E E in a Wedge or v-shape, .the angles of which are contrary to each other in arrangement in their bearings, so that a of the plate, is to preventA the boot from rod, G, having. a screw-thread cut on its front end, and tapped through a projecting lip of the block E, and

passing loosely through a similar projecting lip 011 block E', can be made, by screwing 'it up so as to move the blocks toward each other, to contract the jaws.

The screwrod G extends longitudinally over the skate-iron, works loosely in the lip of the heel block E', and is tapped with a screw-threadthro'gh the. lip of block E, as above described. It has a thumb-piece on its rearend, which is entirely outo' the way in skating, but is veryconveniently operated to tighten or loosen the clamps.

' It lwill be seen by this description thatthe power obtained by the V-shaped slots, acting onthe clampingjaws, is very great, being a combination of screw and Wedge, firmly and securely the sole and heel of a boot or. shoe by the operation of the screw G, rendering no other fastening necessary.

'-The lug or shoulder q', projecting up from the front slipping forward, and maybe placed either .upon the heel-plate, as shown, or upon the front of the sole-plate, when the plate is made the full length.

The pin Ik, on rod G, is turned backwards to loosen the skate'omthe boot;

What I claim as my invention, anddesire to secure by- Letters Patent, is-

1. The adjustable hooked clamps D. D', or their vequivalents, for fastening skates, arranged-to be tightencd and adjusted by means of anadjusting-screw.

2. Constructing askate, having a supporting-plate, with a projecting piece or lug, to prevent the boot from slipping forward, and clamp-fasteuings, adjusted by means of an adjusting-screw.

3. The combination of the movable slotted blocks E E', or their equivalents,

and the clamps are drawn laterally, to gripe' with clamps D D', and the, adjustable screw G, arranged substantially as described. and for the purposes specified.
