3. In a skate clamp, in combination, a pair of 20

sliding movement, threaded means for driving

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

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.
