Abstract

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
144 words
An ice skate blade analyzer comprising a support having foot members provided with coplanar bottom surfaces adapted to rest on an inverted ice skate blade holder and to straddle a part of the blade extending upwardly from the holder, said support having a slot disposed above and between the foot member, a slide member mounted in said slot and disposed substantially parallel to the blade for movement toward and away from the blade edge, said slide having a bottom edge disposed substantially parallel to the bottom surfaces of said foot members, means carried by said foot members for indicating when said support is centered relative to the blade holder supports, and means carried by said slide, adjacent to its bottom edge, for indicating the location of the tangent or high point of the blade edge which contacts said bottom edge of the slide member.
Claim 2
Dependent Claim
144 words
An ice skate blade analyzer comprising a support having foot members provided with coplanar bottom surfaces adapted to rest on an inverted ice skate blade holder and to straddle a part of the blade extending upwardly from the holder, said support having a slot disposed above and between the foot member, a slide member mounted in said slot and disposed substantially parallel to the blade for movement toward and away from the blade edge, said slide having a bottom edge disposed substantially parallel to the bottom surfaces of said foot members, means carried by said foot members for indicating when said support is centered relative to the blade holder supports, and means carried by said slide, adjacent to its bottom edge, for indicating the location of the tangent or high point of the blade edge which contacts said bottom edge of the slide member.
Claim 3
Dependent Claim
37 words
An ice skate blade analyzer as in claim 1, said support including back and front plates, spacers secured between said plates in spaced apart relation to one another and combining with the plates to define the slot.
Claim 4
Dependent Claim
34 words
An ice skate blade analyzer as in claim 2, said slide member comprising a plate having elongated end portions forming abutments for engagement with said spacers for slidably confining the slide in the support.
Claim 5
Dependent Claim
78 words
An ice skate blade analyzer as in claim 2, a follower mounted between one edge of said slide and one of said spacers, and spring means interposed between said last mentioned spacer and the follower for urging the follower into engagement with said edge of the slide to retain another edge of the slide in abutting engagement with the other spacer for retaining said bottom edge of the slide parallel to the bottom surfaces of said foot members.
Claim 6
Dependent Claim
34 words
An ice skate blade analyzer as in claim 2, said front and rear plates having end portions, legs depending from said end portions, said legs having outwardly extending bottom portions defining said foot members.
Claim 7
Dependent Claim
58 words
An ice skate blade analyzer as in claim 5, said means for indicating when the support is centered relative to the blade holder supports comprising wing members secured to the front sides of the foot members of the front plate and having graduations extending along front sides thereof for locating the support centered above the blade holder supports.
