Abstract
Abstract An ice skate blade squaring device comprises a squaring body which is removably mountable to an ice skate blade. The squaring body includes a standard squaring line across one face thereof. Arranged on each end of the squaring line are sets of graduations which are utilized in determining the out of squareness of the skate blade. An angle is provided which is magnetically attachable to the skate blade. The angle is designed to abut against the face of the squaring body having the squaring indica thereon. Once the angle is abutted to the squaring frame, a visual determination of the intersection of a free edge of the angle with the squaring indicia permits a simple and accurate determination of the out of squareness of the ice skate blade. In another embodiment, a squaring body includes an arm pivotally mounted thereto. The arm supports a dial indicator which assists in determining the squareness of the skate blade. The squaring body and arm maintain a dial indicator parallel to the skate blade side surface to assure accuracy in determining out of squareness.

Claim 2
Dependent Claim
83 words
An ice skate blade squareness measuring device comprising: a) a frame, said frame having a plurality of squareness indicia on a face thereof, said frame including means for removably mounting said frame onto a portion of said ice skate blade such that said squareness indicia are perpendicular to a side of said ice skate blade; and b) means removably mountable to a skate blade edge of said ice skate blade for indicating squareness of said blade edge in conjunction with said squareness indicia.
Claim 3
Dependent Claim
51 words
The ice skate blade squareness measuring device of claim 1 wherein said means for removably mounting said frame further comprises a slot in a portion of said frame for receiving said portion of said ice skate blade and means for securing said portion of said ice skate blade in said slot.
Claim 4
Dependent Claim
56 words
The ice skate blade squareness measuring device of claim 2 wherein said frame includes an elongated member having said face thereon and a body attached to said elongated member, said body generally bisecting said elongated member and including both said slot and said means for securing said portion of said ice skate blade in said slot.
Claim 5
Dependent Claim
66 words
The ice skate blade squareness measuring device of claim 2 wherein said means for securing said portion of said ice skate blade comprises a set screw threadably mounted on said frame and extending into said slot for contact with one side of said ice skate blade, tightening of said set screw forcing the other side of said ice skate blade against a side of said slot.
Claim 6
Dependent Claim
65 words
The ice skate blade squareness measuring device of claim 3 wherein said means for securing said portion of said ice skate blade comprises a set screw mounted on said body and extending into said slot for contact with one side of said ice skate blade, tightening of said set screw forcing the other side of said ice skate blade against a side of said slot.
Claim 7
Dependent Claim
77 words
The ice skate blade squareness measuring device of claim 1 wherein said means for indicating squareness comprises: i) an angle having first and second legs, said first leg designed to rest on said blade edge and said second leg having a predetermined width such that a free edge thereof aligns with at least one of said squareness indicia; and ii) a magnet attached to said first leg for removably mounting said first leg to said blade edge.
Claim 8
Dependent Claim
51 words
The ice skate blade squareness measuring device of claim 6 wherein said plurality of squareness indicia comprises: an indicia line extending substantially across said face and a pair of sets of graduations, wherein said pair are spaced apart from each other, each set of graduations being symmetrical about said indicia line.
Claim 9
Dependent Claim
77 words
The ice skate blade squareness measuring device of claim 3 wherein said means for indicating squareness comprises: i) an angle having first and second legs, said first leg designed to rest on said blade edge and said second leg having a predetermined width such that a free edge thereof aligns with at least one of said squareness indicia; and ii) a magnet attached to said first leg for removably mounting said first leg to said blade edge.
Claim 10
Dependent Claim
51 words
The ice skate blade squaring measuring device of claim 8 wherein said plurality of squareness indicia comprises: an indicia line extending substantially across said face and a pair of sets of graduations, wherein said pair are spaced apart from each other, each set of graduations being symmetrical about said indicia line.
Claim 11
Dependent Claim
35 words
The ice skate blade squaring measuring device of claim 9 wherein said indicia line is spaced from said slot a predetermined distance and said second leg has a height substantially equal to said predetermined distance.
Claim 12
Dependent Claim
