Abstract
Abstract A skate structure including a foot plate having downwardly depending sockets, with the latter receiving a resilient cushion blocks therein. An axle housing is nested in the lower end portion of each block, and these elements are secured together by a bolt. The lower threaded bolt end passes through a washer; and the construction is such that neither the bolt nor washer can turn due to the stresses caused during use of the skate. The wheel axle is press fitted in the housing and positioned generally normal to the above-mentioned securing bolt. To prevent interference between the axle and bolt, the axle is offset from the center housing axis, and is also provided with a cut-away portion through which the bolt passes. When a braking member is mounted at the skate toe, the front socket cooperates with the braking member to prevent the latter from turning about its axis.

Dependent Claim
184 words
A roller skate comprising: a. a foot plate, b. a plurality of sockets extending downwardly from said foot plate, c. a resilient cushion block disposed in each said socket, d, a horizontally extending axle support member disposed at the lower end of said block, e. an axle extending through said support member, f. skate wheels mounted on the ends of said axle, g. means to secure said support member to said block, said means comprising: 1. a bore extending downwardly through said block and said support member, 2. a bolt disposed in said bore, 3. a nut on the lower end of said bolt, 4. and a washer member disposed between said nut and said support, h. complimentary engaging flats on said bolt and said washer to lock said bolt against rotation due to torque forces occurring during shating, i. and a recess disposed in the outer wall of said support member remote from said cushion block and with said recess having opposed side walls, j. said washer being generally rectangular and disposed within said recesS and locked against rotation by said side walls.
Claim 8
Dependent Claim
184 words
A roller skate comprising: a. a foot plate, b. a plurality of sockets extending downwardly from said foot plate, c. a resilient cushion block disposed in each said socket, d, a horizontally extending axle support member disposed at the lower end of said block, e. an axle extending through said support member, f. skate wheels mounted on the ends of said axle, g. means to secure said support member to said block, said means comprising: 1. a bore extending downwardly through said block and said support member, 2. a bolt disposed in said bore, 3. a nut on the lower end of said bolt, 4. and a washer member disposed between said nut and said support, h. complimentary engaging flats on said bolt and said washer to lock said bolt against rotation due to torque forces occurring during shating, i. and a recess disposed in the outer wall of said support member remote from said cushion block and with said recess having opposed side walls, j. said washer being generally rectangular and disposed within said recesS and locked against rotation by said side walls.
Claim 9
Dependent Claim
6 words
a bolt disposed in said bore,
Claim 10
Dependent Claim
6 words
a bolt disposed in said bore,
Claim 11
Dependent Claim
6 words
a bolt disposed in said bore,
Claim 12
Dependent Claim
6 words
a bolt disposed in said bore,
Claim 13
Dependent Claim
67 words
The skate of claim 1: a. wherein said rectangular washer includes a generally flat base which is disposed in said support member recess as well as downwardly extending flanges disposed on the ends of said washer, b. said flanges being disposed in close proximity to said nut to provide stop means preventing substantial turning of said nut in response to relatively low torque forces occurring during skating.
Claim 14
Dependent Claim
34 words
The skate of claim 2 in which said flanges are slightly flexible so that the said stop means are overcome and said nut can rotate through 360* when relatively high torque is applied thereto.

Dependent Claim
9 words
a nut on the lower end of said bolt,
Claim 16
Dependent Claim
9 words
a nut on the lower end of said bolt,
Claim 17
Dependent Claim
9 words
a nut on the lower end of said bolt,
Claim 18
Dependent Claim
9 words
a nut on the lower end of said bolt,
Claim 19
Dependent Claim
56 words
and a washer member disposed between said nut and said support, h. and a recess disposed in the outer wall of said support member remote from said cushion block and with said recess having opposed side walls, i. said washer being generally rectangular and disposed within said recess and locked against rotation by said side walls.
Claim 20
Dependent Claim
56 words
and a washer member disposed between said nut and said support, h. and a recess disposed in the outer wall of said support member remote from said cushion block and with said recess having opposed side walls, i. said washer being generally rectangular and disposed within said recess and locked against rotation by said side walls.
Claim 21
Dependent Claim
30 words
The skate of claim 3 in which said nut is thicker than the downward extent of said flanges to provide a wrench gripping surface free of interference by said flanges.
Claim 22
Dependent Claim
79 words
and a washer member disposed between said nut and said support, h. complimentary engaging flats on said bolt and said washer to lock said bolt against rotation due to torque forces occurring during shating, i. and a recess disposed in the outer wall of said support member remote from said cushion block and with said recess having opposed side walls, j. said washer being generally rectangular and disposed within said recesS and locked against rotation by said side walls.
Claim 23
Dependent Claim
79 words
and a washer member disposed between said nut and said support, h. complimentary engaging flats on said bolt and said washer to lock said bolt against rotation due to torque forces occurring during shating, i. and a recess disposed in the outer wall of said support member remote from said cushion block and with said recess having opposed side walls, j. said washer being generally rectangular and disposed within said recesS and locked against rotation by said side walls.
