IMPROVEMENT IN sKATEs.

Specification forming part of Letters Patent No. 47,682, dated May 9, 1865.

To all whom it may concern.-

Be it known that I, EDGAR MURRAY, of the city and State of New York, have invented, made, and applied to use a certain new and useful [Improvement in Skates and Ido hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawings, making part of this speeitcation, wherein-'- Figure l is alongitudinal section of my improved skate, and Fig. 2 is a plan of the runner and clamps, the sole-plate of the skate being shown in red lines.

Similar marks of reference denote the same parts.

Skates have heretofore been made with a movable or hinged runner, acting to bind the skate to the boot-sole when said runner is pressed toward the foot.

The nature of my said invention consists in a movable runner, combined with a link and adjustable heel-screw, and with a sliding camplate that operates clamps that act upon the sides of the boot-sole to secure the same. Thus the one movement of the runner effectually secures the skate to the foot or entirely7 relieves the same.

In the drawings, a is the sole-plate, of any desired size or shape. b is the heeLclip, formed at the baek end of the plate a to receive the bootheel. o is the runner, hinged at d to the sliding plate e, that is formed with camgrooves, taking pins upon the sliding clamps f f, that grasp the sides of the bootsole, and

gis a screwor rivet, sliding in a slot at the front portion of the plate a, to guide and support the forward end of the slide-plate e.

h is a link, jointed at i to the runner c and extending through a slot n soleplat-e a, Where it terminates as a nut, receiving the heelscrew k.

L is a stud on the under side of a, into a notch in which the runner passes and is supported, and m is a spring-latch, taking a pin on the side of the runner c, and holding the same in position when pressed toward the soleplate.

It will now be seen that the screw k is to be adjusted so as to leave the proper distance between its end andthe heel-elip b for the reception ofthe boot-heel and itssecure clamp-V ing, and the act of compressing the heel by the pressing of the runner toward the soleplate causes the runner to force the plate-e forward and by its cam-grooves draw the clam ps fftightly against the sides ofthe boot-V sole to secure the skate rmly to the boot.

Vhat I claim, and desire to secure by Let ters Pa;ent, is-

The combination of the movable runner c, link It, and heel screw 7c, with the sliding plate e and clamps ff, taking the sides of the sole ofthe boot, as specied.

In witness whereof I have hereunto set my signature this 24th day of lVIarcll1,A. D 1865.

EDGAR MURRAY.
