`v arins of the clamps'37 being pivoted together at 4the point 39. p y

In order to operate the plate '35 and the clamps 37 I provide a central disk 40 which is directly but pivotally connected to the Larin'of'onenof thev clamps 87 and which op- "erates the'plate 35 by means of'a pivotal connection with 'a ylink 41 :which is pivote'd in turn to1 the plate 35. Fixed to the disk 4.0 is anarmLQ b'ywhicli the diskmay be clamped and Ipprovide' a' series of teeth 4B with which the arm 42 is adapted to engage land which holdssai'd arm in vadjusted position. lvembe'rs 35 `and 37 n1ay be adjusted tofjdiiierent sized shoes by adjusting the fpoint '39 Where the arms 'of the sole clamp -are-'pivoted together,- and also the point 44 Where thelik'tl connects'wi'th the disk 40. 'n' 'order 'toprovide for steering the skate I use only' 'one wheel. such as 17'Which is pivoted in a'yoke 16,'said yoke being provided with an lupwardly extending'short 'shaftlt which is journaled in the plate 21,

' and which is squared at'its upper endl to re-V eeive the squared end of a-socket l5 which 'is 'extended upwardly in a shaft 15 which carries at its upper end a steering Wheel es. fsa. Fig. 9.

'In'order' to provide for braking of the skates on hills, or in'cases of emergency, l provide two brake arms such as @iT-i7 which are pivotally connected to .the Aplate Q1 an'd'ivhich' carry shoes 48 adapted to enlfgage with the rims' of the Wheels Levers Ll''are pivoted at the point Qand extend diagonally toward the 'center line ,of the iplatc'Ql, their inner .ends beingpifovided with slots such as which aread'apted to 'receive a pin 5l. The pin 5l also passes through the end o f'the link 52, the, forward 'entl of which connects to a; cord 14C which passes'around a guide pin 53 and thus is carried up alongside of the shaft 15 so as to be convenienttothe skater. The brake shoes 48 are normally Withdrawn from contact with the 1Wheels by means of -springs suchas 61 which are pi'v'otally connected to i,sweght upon the plate 1, the member@ Wlll'becompre'ssed'between the plates l and Elfand'that the point 3 Will'be carried rear- Wardly around'the center 'of the axle as an tins'Willb-e that the paWl 4 will be lifted andthe Wheel 5 with the axle 6 will be ro- 'tatedl When the skater shifts his Weight to' the other skate the springs 9 Will raise Vthe lplate l to its normal position Wherepair by means of links such as 50-"50, but

the skates may also be operated Without being interconnected.

lt will be-understood that while l hare shown' and described the preferred form oi. my invention, various modifications thereof may be'niade `Without departing from 'the spirit of my invention, and that I conteniplate all Isuch;modifications as are mechanically eqnivalent to the device shown and described herein.

Having thus described my invention, what l claim4 is l. A skate comprising in combination, a frame, a pair of Wheels journaled to said frame, a plate 'carried by said frame and movable relatively thereto, a resilient niember having one end fixed to said frame and being bent into contact With said movable plate, arms pirotally connected to the axle of said Wheels and also to said member, a toothed wheelcarried by the axle of said Wheels, and a pawl adapted to engage said toothed Wheel, said pawlfbeing pivoted to said membernear the end thereof opposite to its place of attachment to the frame 2. A skate comprising in combination, a frame, a pair of rear wheels rotatably con-- nectedto said traine; a plate carried by said frame and adapted to more relatively thereaxis at the saine time that the point 27 is l carried upward. The result of these moto, springs intermediate said plate and said l frame, toothed Wheels fixed to the axle of said Wheels, and pawls pi\' otally connected to said movable plate and arranged to operate 'said toothed Wheels from energy derived from said springs.

ln 'testimony whereof l ailix my signa ture inthe presence of two Witnesses.
