The features of novelty which I believe to be characteristic of my invention are set forth with 60 particularity in the appended claims. My in upstandingrportion is. preferably bent inwardly slightly at the top as at‘ Ma and Mb: and notches‘ may be provided on opposite edges of the clamp as at l5b to receive a band of elastics I60. and [61). Thus it will be seen that the sole engaging 60. 2,116,204" 2 portion may swing through an are upon the hori zontal portion. For the purpose of limiting this bers, each transverse member and cooperating L—shaped clamp having portions arranged to movement I may extend the horizontal portion engage each other at a predetermined angular position of said L-shaped clamp, whereby the inwardly on a taper as at l8a and Nb so that at the desired limit of forward movement of the outside of the clamp, the tapered portion strikes against the forward face of the plates 9a and 8b, as indicated by the dotted lines in Fig. 3. The limit of movement in the other direction backward movement of said swiveled L-shaped clamp is limited. ' is preferably provided by cutting away the outer 10 extremity of the horizontal portion at an angle outwardly to the rear as at Ila and I‘lb so that at the limit of rearward movement the outermost part of the horizontal portion engages the verti cal portion of the sole engaging part, as indi 15 cated by the position of the left-hand clamp in Fig. 3. It will be understood, however, that the plates 2. In a skate clamp, in combination, a pair of transverse clamping members secured to the un der side of the sole of the skate for transverse sliding movement, threaded means for driving 10 said clamping members, a pair of L-shaped shoe~ engaging clamps respectively swiveled upon the external part of said transverse members, each transverse member and cooperating L-shaped clamp having portions arranged to strike to limit the backward movement of said L-shaped clamp, the vertical sole-engaging portion of said clamp having a narrowed zone to position an elastic for 8a and 812 may serve to limit the backward 20 movement of the clamp, if desired, but in this in stance it would be necessary to extend them fur ther to the rear and I prefer to utilize the con tact between the outer and inner portions of the clamp for providing the rear stop. 25 ' Referring now more particularly to Figs. 4, 5 contact with the shoe sole. 3. In a skate clamp, in combination, a pair of 20 transverse clamping members secured to the un~ der side of the sole of the skate for transverse sliding movement, threaded means for driving said clamping members, a pair of L-shaped shoe 25 engaging clamps respectively mounted to swivel upon the external part of said transverse mem and 6, I have shown a modi?ed form of clamp se cured to the skate in a somewhat di?erent man ner. In this instance no down-turned ?anges may be provided on the skate sole, but there may 30 be instead rivets 20a. and 20b extending down wardly from the sole of the skate and having an enlarged lower head spaced from the sole of the skate by a distance su?icient to permit the hori bers, and means for limiting the turning move ment of said clamp in either direction to less than 90°. 4. In a skate clamp, in combination, a pair of 30 transverse clamping members secured to the un der side of the sole of the skate for transverse sliding movement, threaded means for driving said clamping members, a pair of L-shaped shoe~ zontal portion of the clamp, each of which is 35 provided with slots 2 la. and 2 lb respectively, to be held against the sole of the skate thereby. The general formation of the horizontal portion of the clamp and of the sole engaging portion is other wise similar to that already described with the exception that the sole engaging portion in this 40 instance is pivoted at the rear outward extremity of the horizontal portion of the clamp and the pivoted portion is not provided with the inwardly extending arm as before. In this instance 22a; and 22b designate the riv 45 ets about which the outer portion of the clamp is 55 swingable and, as before, the faces 23:]. and 231) project outwardly to the rear, and the rear ex tremity contacting with the vertical face of the sole engaging portion forms a stop limiting the rearward movement. In this instance it may be desirable to increase the angle at which the outer ends of the horizontal portions are cut away and if desired the con?guration of the edges 23a and 231) may be made such that the striking of the vertical portion against the forward edge consti tutes a stop limiting the forward motion. While I have shown and described certain pre ferred embodiments of my invention it will be understood that modi?cations and changes may 60 be made without departing from the spirit and scope thereof, as will be clear to those skilled in the art. I claim: 1. In a skate clamp, in combination, a pair of 65 transverse clamping members secured to the un der side of the sole of the skate for transverse sliding movement, threaded means for driving said clamping members, a pair of L-shaped shoe engaging clamps respectively mounted to swivel 70 upon the external part of said transverse mem 15 engaging clamps swiveled upon the external part 35 of said transverse members, said L-shaped clamps and said transverse members having por tions arranged to strike to limit the backward movement of the clamp, and said L-shaped clamp having a projection beyond the pivot arranged to 40 strike an abutment to limit the forward move— ment of the clamp. 5. In a skate clamp,'in combination, a pair of transverse clamping members secured to the un— der side of the sole of the skate for transverse 45 sliding movement, and having a longitudinal slot therein, the forward outer ends of said trans verse members being cut away, a pair of L-shaped shoe-engaging clamps respectively swiveled upon the rear outer extremity of said transverse mem 50 bers, said L-shaped clamps and said transverse members having portions arranged to strike to limit the backward movement of the said L shaped clamps. 6. In a skate clamp, in combination, a pair of 55 transverse clamping members secured to the un~ der side of the sole of the skate for transverse sliding movement, threaded means for driving said clamping members, a pair of L-shaped shoe engaging clamps swiveled upon the external part 60 of said transverse members, the vertical portion of each shoe~engaging clamp having a reduced width intermediate its ends and a band of buffer material surrounding said reduced portion, said transverse members and said L-shaped clamps having portions arranged to engage each other at a predetermined angular position of said L~ shaped clamp, whereby the backward movement of said L-shaped clamps is limited. 70 IRVING J AFFEE.
