Instead of the dove-tailed groove in the projec-V tion o, the groove may be. If desired, the clips a may be arranged to move diagonally on the plato B, as indicated by the dotted lines inlgl, and secured-from turning by being fitted in grooves or other v-isc, by which means they will be less likely to spread in use. ,By these simple means the skate is rigidly and securely fastened to the foot. By thus springing the heel around, the clips a are made to clasp tightly on the'sole, and the plate n, attached to the heel of the boot at the same time, slides into the groove in the piece o, where it, is securely held from moving sidewise by the catch'e entering a notch or hole in thevlipt of the plate n. 1, the clips a being iirst adjusted tosnit the width i of the sole, and the skate is then swung around at the heel until it is brought straight under the foot. The skate is applied to the foot in the position indicated by the blue lines on iig. 2, the spring and catch being also shown in iig. On the frontof this plate,'-at its lower edge, is a projecting lip, t, formed to't accurately in the groove in the rear face'of the projection o, on plate C.,V The piece o has a hole in it, through which projects the point of a catch, e, attached'to a`spring,f, vvhich is secured to the lug b of plate C, as shown in iig. On the front face of the heelof the boot or shoe is secured a small metal plate, at, shown, with its screws for attaching it, Ain fig. 1,' it forming the segment of azcircle, having its centre at the centre of the front plate B. 'the rear face oi" this piece o, above the plate C, is formed a dove-tailed groove, as shown in g. At the front edge of the heel plate C is secured a raised piece, o, which extends entirely'across the plate transversely. ![]() 1, one being considerably in advance of the other, the object of which arrangement will be hereinafter stated.

Another plate, C, is attached for the heel to rest on these plates being made with a lug or shank, projects downward from their under sideand straddle the blade A, to which they are fastened byvscrews or rivets, as shown in gs. ![]() To the front portion of the blade is secured a plate, B, for thc vfront portion of the foot to rest on.
