Abstract
Abstract A holder for a speed square is cylindrically shaped to receive an edge of the square and allow the balance of the square to project out, away from the body. In one form, the slot in the square receives a curved tang, and the square rests on a cam surface so gravity urges the square around and down to a holding slot. A complementary slot prevents loss of the square when a person bends over. In another form of the holder, a straight slot receives the flanged edge of the square. In either case, the tool holder may have a flared base for greater stability when the holder is set on a flat surface.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
277 words
A tool holder, for carrying a tool having an aperture therein on a person's belt or the like, said tool holder comprising a generally cylindrical body having a top and bottom edge, a tool holding slot defined in said cylindrical body for receiving the tool to be held, said tool holding slot extending parallel to the centerline of said cylindrical body and defining a locking shoulder on at least one side of said slot for preventing lateral movement of said tool to be held, and a means for selectively receiving a belt of a user for carrying said tool holder on a person, such that said cylindrical body would be oriented in a generally vertical direction with respect to the user so that said tool holding slot would extends generally, said cylindrical body further defining a cam slot extending from said tool holding slot at an intermediate portion thereof to the top edge of said body, the intersection of said cam slot with said tool holding slot defining said locking shoulder, a tang formed from the wall of said body between said cam slot and top edge and extending circumferentially thereof, the lower edge of said tang comprising the upper edge of to said cam slot, the lower edge of said cam slot comprising a cam surface extending downwardly and circumferentially of said cylindrical body, the arrangement being such that said tang is receivable through said aperture of said tool to be held and said tool rests on said cam surface, said can surface being downwardly sloped such that said tool to be held is movable by gravity along said cam surface towards said tool holding slot.
Claim 2
Dependent Claim
277 words
A tool holder, for carrying a tool having an aperture therein on a person's belt or the like, said tool holder comprising a generally cylindrical body having a top and bottom edge, a tool holding slot defined in said cylindrical body for receiving the tool to be held, said tool holding slot extending parallel to the centerline of said cylindrical body and defining a locking shoulder on at least one side of said slot for preventing lateral movement of said tool to be held, and a means for selectively receiving a belt of a user for carrying said tool holder on a person, such that said cylindrical body would be oriented in a generally vertical direction with respect to the user so that said tool holding slot would extends generally, said cylindrical body further defining a cam slot extending from said tool holding slot at an intermediate portion thereof to the top edge of said body, the intersection of said cam slot with said tool holding slot defining said locking shoulder, a tang formed from the wall of said body between said cam slot and top edge and extending circumferentially thereof, the lower edge of said tang comprising the upper edge of to said cam slot, the lower edge of said cam slot comprising a cam surface extending downwardly and circumferentially of said cylindrical body, the arrangement being such that said tang is receivable through said aperture of said tool to be held and said tool rests on said cam surface, said can surface being downwardly sloped such that said tool to be held is movable by gravity along said cam surface towards said tool holding slot.
Claim 3
Dependent Claim
25 words
A tool holder as claimed in claim 1, and further including a flared base on said cylindrical body for providing stability for said tool holder.
Claim 4
Dependent Claim
54 words
A tool holder as claimed in claim 2, wherein said tool to be held is a speed square having a slot parallel to the hypotenuse of the square, said tang being receivable in said slot in said square, said body having a diameter sufficient to receive said square between said hypotenuse and said slot.
Claim 5
Dependent Claim
43 words
A tool holder as claimed in claim 2, and further including a complementary slot aligned with said tool holding slot, said complementary slot being adjacent to said tang for preventing motion of said speed square along said tang when said body is inverted.
