Letters Patent No. 98,237, dated December 28, 1869.

IMPROVEMENT IN smiles The Schedule' 'telen-cd to in these Letters Patent and making part of the same.

lo all 'urhom'it may concern.-

Be it known that I, CHARLES T. DAY, of Newark, in the county of Essex, and State `of N ew J ersey, have invented a new and improved Skate; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference heilig had to the accompanying drawing, forining part of this specification.

Figure 1 represents a sideview of my improved skate.

Figure 2 is an inverted plan, partly in section, of the same.

Similar letters of reference indicate corresponding part-s.

This invention relates to certain improvements on the skate for which Letters latcnt ot' the United States, No. 40,916, were granted to me on the 15th day ot'Deccmher, 1863.

lhe object cfa-.the present invention is to facilitate the adjustment 'of the toe and heel-jaws by so setting the adjusting-screw that it` can be easily reached by t ne wearer.

The present invention consists in pivoting the clamping-levers, which -carry the jaws, together, and

in forming a swivel-mit on each pair ot such levers,

I-so that the right and left-hand adjusting-screw can be fitted through both the said nuts in' a diagonal position.

Int-he skate described in the aforesaid Letters Patent, the screw was set longitudinally, and was Vtherefore difficult to reach, while the diagonal screw which retains the advantages of the longitudinal screw, can be easily reached and operated.

A, in the drawing, represents A'the skate-runner, having the standards B B, which sustain the foot and heel-plates C l), respectively.

E E are the front clamping-levers, bearing the front jaws a and F h" are the back clamping-levers, hearing the jaws b.

A11 these said levers are curved, and have curved slots, c c, through which pins or screws, d, projecting from the under sides of the foot and heel-plates, are fitted. f

The lever E is longr than E', and F longer than F', the inner ends of and F heilig diagonally opposite each other.

The lever E' is, at its inner end, pivoted bya pin, f, to the level E, andin the same way is the inner end .of F' pivoted to F by a pin, f.

,'lhe longitudinal adjustment of each pair of levers causes them to more on the pins d so as to set the jaws apart orcontract the same.

This longitudinal adjustment is obtained hy means of a right and left screw, G,which is titted through nuts g h, that are respectively pivoted to the Ainner cndsot'the levers E F, so that they can freely turn ou -their pivots.

vAs by turning the screw G the nuts are forced further apart, the clan'ip-levers are moved outward, to spread the jaws, while the latter will be contracted when the nut-s are drawn together.

The screw, it will be secu, is placed diagonally, and can therefore be easily reached, as easy as a. itransverse screw, without doing away with the advantages of the longitudinal screw.

On the front end of the heel-plate is arranged an upward-projecting lng, i, with a backwardprojecting prong-or point, j, which serves to retain the heel and boot in position, longitudinally as well as vertically.

Having thus described my invention,

I claim as new, Aand desire to secure by Letters Patcntl. The clamping-levers, pivoted together in pairs, substantially as herein shown and described.

2. The combination ot` the clamping-levers withthe swivel-nuts g h and diagonal screw G, all arranged as set forth.

CHARLES .l. DAY.
