UNITED STATES PATENT 'OFFICE GEORGE B. TURRELL, OF SOUTH ORANGE, NEV JERSEY, ASSlG NEE OF MARY ANN LOVATT AND THOMAS G. LOVATT, y DEOEASED.

SNVA t'lVVOUT, EXEOUTORS OF JOHN IMPROVEMENT IN sKATEs.

Specification forming part of Letters Patent No. 28,495,

dated MayQJ, 1860; reissue No. 3,186, dated November 10, 1868; =extended seven years; reissue No. 6,369, dated April 6, 1875; reissue No. 7,151, dated May 30,

1876; application tiled April 22, 1876.

To all whom it 'may concern Bc it known that JoHN LOVATT, formerly ot Newark, in the county ot' Essex and State of New Jersey, now deceased,did invent a new and useful Improvement in Clamping- Skates to Boots or Shoes; and the following is declared to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, formingV a part of this specification.

Before this invention a skate had been made witheclamp's to hold the4 skate to the sole and heel of the boot'or shoe, and such clamps were movable, to accommodate varying sizes of boots and shoes, and retained in position by bolts and nuts that held the clamps to the sole or heel plates. The natureof the present invention consists in the combination, with a skate and lateral acting clampsrof mechanism that operates to move the clamps toward each other with sufficient force to canse them to grasp the sole, and holdthe skate to the boot or shoe.

In the drawings, the improved skate is represented in one of the forms devised by said LovATT. v f

Eigure 1 is a longitudinal .vertical section, taken through the heel and sole plates, showing the screw-rod and movable pieces for adjusting the `clamps for the sole of the boot.

Fig.` 2 is a 'top view of the skate, showing the four clamps Vand the movable slotted blocks'.l Fig. 3 is a perspective view of one of the slotted blocks detached from the foot-plate of the skate. l.

A represents the runner or skateiroinof any suitable shape; andy B B are the standards, which support the heel and sole plates O O', and to which the heel .and sole plates are secured. Theseplates are of sufficient 1engthand width to give a firm 1and steady bearing for the feet.- D D D' Dl are the clampbars, which have their 'edges beveled' down, so that they will ft in suitable slots made to receive them in theplate vC O'. lTheir ends are turned up and slightly over, and made sufficiently sharp toserve as jaws,'whch will tained from Athe screw,

grasp thc edges of the leather sole or heel firmly. These clamping-jaws are shown by dotted lincs,'Fig. l, as made with pins a c projecting into groovesor slotsb in moving plates or blocks E E'. These moving plates orblocks are represented as under the sole and heel plates O C', and suitably held to .these plates between guides, which only allow them to have a longitudinal movement. The grooves b are cnt into the faces ot' moving plates or blocks 'E E in a wedge or V shape, the angles of which are in opposite directions, so, that a rod, G, having a screw-.thread cnt on its front end, and tappedthrough'a projecting lip of the block E, and passing` loosely through a similar projecting lip or block, E', can be made by screwing it up' to move the blocks toward each other to contra-ct the jaws, or by the reverse movement to open the jaws.

By this device the longitudinal movement of the motor communicates a lateral move `ment to the clamps throughthe agency of such inclined or V-shaped surfaces.

The screw-rod Gr works loosely in the lip of the heel-block E', and is tapped with a screwthread through the lip 'of plate or'block E, as

abovedescribed. It has a thumb-piece on its end, which is entirely out of the way in skating, but. is very conveniently operated to tighten or loosen the clamps. rlhe power ohoperatic g upon the lateral clamps, is sufficient to move said clamps, and cause them to grasp the sole with the force required for iirmly holdin gthe skates to the boot or shoe, and when one pair of clamps closes upon the heel or sole the clamp operating mechanism is not arrested lin its movement, but is continued so as to close the other pair ot' clamps, and hence both pairs of clamps are properly closed, 'and nearly the same pressure is exertedupon all the clamps, and the pressure'upon one clamp becomes a resistance in operating the other, because the parts operate in opposite directions.

` In consequence of. using slots and pins between the actuating power and the clamps, the actuating power is rendered much more fthe clamps on the sole and heel are operated n'pon the heel-plate, as shown, or upon the front of thesole-'piate, when Ythe .plate is made Vloosensthe clamps of the skatesfrom the efficient upon the clampskand when these'. moving plates or blocks are used as shown.,

simultaneously. v

The lug or sh'onider g, projecting up from the frontv oftheplate, is to prevent the boot slipping forward, and may be placed either the full length. A' pin, h, through the rod G when tue screw isturned backward.

What is'claimed vas the inventionof the said LovA'r'r,s--` p v 1. The combination, in a skate, of laterally- .slidingrclamps for. grasping thesolefa platev or rest'for the foot, and mechanismfor moving and holding the clamps, substantially as specified.

y 2. The combination,l with the clamps for grasping the sole and clamps for grasping the heel, of mechanism acting between such clampsv in opposite directions,v so that one set ofclamps acts-asaresistance in closing the other set ot' clamps, substantially as set forth.

3. The combination, lin a skate, ot' laterallymoving clamps, pins, inclined slots, and mechanism; lfor operating and holding such clamps, substantially as set forth.

4. The combination, in a skate, of a plate or rest for thefoot, laterallysliding clamps, mechanism that moves and holds such clamps and transfers a longitudinal motion intoV a transverse motion, and clamps for grasping the heel, suostantially.as spe "ed.
