Abstract
A glass cutter and an accessory to allow circular cuts are disclosed. The glass cutter includes a barrel having an axial opening formed of two sections: a smooth and a tapped section, a tapered holder for releasably securing a cutter wheel in the barrel's smooth section, and a spring-biased shaft to be secured within the tapped section and provided with a finger control member. Preferably, the shaft is axiably adjustable. Preferably, the barrel has a knurled outer periphery. Preferably, the holder is formed of stainless steel and the remaining parts are of aluminum.
Claims17
A glass cutter comprising:
- (a) a barrel member having a through axial opening formed of two sections, one of said two sections being smooth-walled and having a smaller diameter and a shorter axial length than the second tapped section of said two sections:
- (b) a holder formed with a tapered end and a stem for holding a cutter wheel at said tapered end, said stem provided with a tangential flat side facing said tapered end and designed to be received within said smooth-walled section of said barrel member;
- (c) an externally-threaded shaft member provided with a concentric spring-biased shaft and an internally-threaded lock nut meshing with and axially displaceable along said externally-threaded shaft member, said shaft member designed to be received within said tapped section of said barrel member;
- and
- (d) a finger control member provided with an axially extending sleeve designed to fit over said spring-biased shaft of said shaft member.
An accessory tool for a glass cutter to allow it to cut circular patterns of varying sizes, comprising:
- a flat stand having a vertical tapped neck;
- an externally-thread bar provided with a lock nut and designed to be received within said vertical tapped neck;
- (c) a head member freely rotatable about the free end of said externally-threaded bar and formed with an axial hole and a bore normal to said axial hole;
- (d) a rod provided with markings of units of length and designed slidably to fit within said bore of said head member;
- and
- (e) means to secure said rod within said bore, said means including a screw designed to fit within said axial hole of said head member and an actuating member designed to rotate said screw and having a normal, free-wheeling position and an operative screw-engaging position.
A combination glass cutter and accessory to permit said cutter to cut circular cuts comprising:
- (a) a barrel member having an axial opening formed of two sections:
- a smooth-walled section and a tapped section, and a radial opening;
- (b) a holder for holding a cutter wheel and designed to be releasably secured within said smooth walled section;
- (c) a shaft member designed to be secured within said tapped section;
- (d) a finger control membr designed to fit over said shaft member;
- (e) a flat stand having an upstanding neck portion;
- (f) a bar member designed to be received in said upstanding neck portion and provided with a freely rotatable head formed with an axial hole and a bore normal to said hole;
- (g) a rod provided with markings of units of length and designed slidably to fit within said bore;
- and
- (h) first means to secure one end of said rod within said radial opening of said barrel member and second means to secure said rod within said bore;
- (i) said shaft member being spring biased and designed for axial adjustment with respect to said barrel member.
