Abstract
Abstract A garment-fastener assembling apparatus includes a drive mechanism for reciprocating an optical position indicator toward and away from an indicating position located in registry with the path of movement of a punch. The drive mechanism is constructed to operate under direct control of the movement of the ram so that the position indicator is reciprocated without interference with the punch or any other movable part of the apparatus and without causing prolongation of the cycle time of the apparatus.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
223 words
An apparatus for assemblying a pair of fastener elements of a garment fastener with a garment fabric disposed between the two fastener elements, comprising: (a) a frame supporting thereon a guide block; (b) a ram vertically reciprocably supported on said guide block and having a punch connected thereto; (c) an optical position indictor for indicating a position on the garment fabric where the two fastener elements are to be attached; and (d) a drive mechanism for reciprocating said position indicator between an indicating position located in registry with the path of movement of said punch and a standby position remote from the path of movement of said punch, said drive mechanism including (i) a driver slidably mounted on said guide block and horizontally reciprocable in response to vertical movement of said ram, (ii) a pivot lever pivotably supported by said frame and angularly reciprocable in response to horizontal movement of said driver, (iii) a slide bar slidably mounted on said guide block and supporting said optical position indicator, said slide bar being pivotably connected with said pivot lever to reciprocate said optical position indicator between said indicating position and said standby position in response to angular movement of said pivot lever, and (iv) biasing means for urging said slide bar in a direction to move said optical position indicator toward said indicating position.
Claim 2
Independent Claim
223 words
An apparatus for assemblying a pair of fastener elements of a garment fastener with a garment fabric disposed between the two fastener elements, comprising: (a) a frame supporting thereon a guide block; (b) a ram vertically reciprocably supported on said guide block and having a punch connected thereto; (c) an optical position indictor for indicating a position on the garment fabric where the two fastener elements are to be attached; and (d) a drive mechanism for reciprocating said position indicator between an indicating position located in registry with the path of movement of said punch and a standby position remote from the path of movement of said punch, said drive mechanism including (i) a driver slidably mounted on said guide block and horizontally reciprocable in response to vertical movement of said ram, (ii) a pivot lever pivotably supported by said frame and angularly reciprocable in response to horizontal movement of said driver, (iii) a slide bar slidably mounted on said guide block and supporting said optical position indicator, said slide bar being pivotably connected with said pivot lever to reciprocate said optical position indicator between said indicating position and said standby position in response to angular movement of said pivot lever, and (iv) biasing means for urging said slide bar in a direction to move said optical position indicator toward said indicating position.
Claim 3
Dependent Claim
25 words
