Abstract
Abstract An improved deleaver for a continuous business forms assembly for separating the stationery plies and interleaved carbon plies from each other. The invention features a unique carbon turning bar assembly whereby the same is permanently affixed to the machine and yet may be moved between operative and inoperative positions, the latter being used when continuous business forms assemblies not having interleaved carbon are being processed. Also featured is a door in the wall of the first chute which may be selectively opened or closed. When extremely large forms are being processed such that they cannot rest generally parallel to the bottom of the first chute, the door may be opened to allow efficient processing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
199 words
A deleaver for separating superimposed plies of stationery and interleaved carbon plies of a continuous business forms assembly including at least one upwardly open chute for receiving at least one stationery ply of the continuous business forms assembly, a powered carbon take-up reel associated with the chute for removing a carbon ply adjacent said one stationery ply from said one stationery ply, a carbon turning bar in said chute about which said carbon ply may be trained and directed to said carbon take-up reel, and means substantially permanently affixing one end of said carbon turning bar to said deleaver so as to prevent removal of said carbon turning bar from said deleaver except for servicing or the like, including means mounting said one end for selective movement of said carbon turning bar on said deleaver between operative and inoperative positions, said mounting means including first means for allowing said carbon turning bar to slidably reciprocate longitudinally along its axis, and second means to allow the carbon turning bar to pivot between said operative position and said inoperative position, said first means further selectively rendering said second means inoperative when the carbon turning bar is pivoted to the operative position.
Claim 2
Dependent Claim
199 words
A deleaver for separating superimposed plies of stationery and interleaved carbon plies of a continuous business forms assembly including at least one upwardly open chute for receiving at least one stationery ply of the continuous business forms assembly, a powered carbon take-up reel associated with the chute for removing a carbon ply adjacent said one stationery ply from said one stationery ply, a carbon turning bar in said chute about which said carbon ply may be trained and directed to said carbon take-up reel, and means substantially permanently affixing one end of said carbon turning bar to said deleaver so as to prevent removal of said carbon turning bar from said deleaver except for servicing or the like, including means mounting said one end for selective movement of said carbon turning bar on said deleaver between operative and inoperative positions, said mounting means including first means for allowing said carbon turning bar to slidably reciprocate longitudinally along its axis, and second means to allow the carbon turning bar to pivot between said operative position and said inoperative position, said first means further selectively rendering said second means inoperative when the carbon turning bar is pivoted to the operative position.
Claim 3
Dependent Claim
238 words
A deleaver for separating superimposed plies of stationery and interleaved carbon plies of a continuous business forms assembly including at least one generally upwardly opening chute having a side wall for receiving at least one stationery ply of the continuous business forms assembly, a powered carbon take-up reel associated with the chute for removing a carbon ply adjacent said one stationery ply from said one stationery ply, a carbon turning bar in said chute about which said carbon ply may be trained and directed to said carbon take-up reel; and means mounting one end of said carbon turning bar on said side wall for movement between a first, operative position wherein said carbon turning bar extends into said chute and a second, inoperative position adjacent said side wall and within said chute, said carbon turning bar being maintained in said second position by gravity until moved to said first position, said mounting means including means substantially permanently affixing said one end to said deleaver so as to prevent removal of said carbon turning bar except for servicing or the like, first means for allowing said carbon turning bar to slidably reciprocate longitudinally along its axis and second means to allow the carbon turning bar to pivot between said first, operative position and said second, inoperative position, said first means further selectively rendering said second means inoperative when the carbon turning bar is pivoted to said first, operative position.
Claim 4
Dependent Claim
238 words
A deleaver for separating superimposed plies of stationery and interleaved carbon plies of a continuous business forms assembly including at least one generally upwardly opening chute having a side wall for receiving at least one stationery ply of the continuous business forms assembly, a powered carbon take-up reel associated with the chute for removing a carbon ply adjacent said one stationery ply from said one stationery ply, a carbon turning bar in said chute about which said carbon ply may be trained and directed to said carbon take-up reel; and means mounting one end of said carbon turning bar on said side wall for movement between a first, operative position wherein said carbon turning bar extends into said chute and a second, inoperative position adjacent said side wall and within said chute, said carbon turning bar being maintained in said second position by gravity until moved to said first position, said mounting means including means substantially permanently affixing said one end to said deleaver so as to prevent removal of said carbon turning bar except for servicing or the like, first means for allowing said carbon turning bar to slidably reciprocate longitudinally along its axis and second means to allow the carbon turning bar to pivot between said first, operative position and said second, inoperative position, said first means further selectively rendering said second means inoperative when the carbon turning bar is pivoted to said first, operative position.
Claim 5
Dependent Claim
153 words
A deleaver for separating superimposed plies of stationery and interleaved carbon plies of a continuous business forms assembly including at least one chute for receiving at least one stationery ply of the continuous business forms assembly, a powered carbon take-up reel associated with the chute for removing a carbon ply adjacent said one stationery ply from said one stationary ply, a carbon turning bar in said chute about which said carbon ply may be trained and directed to said carbon take-up reel, and means substantially permanently affixing one end of said carbon turning bar to said deleaver so as to prevent removal of said carbon turning bar from said deleaver except for servicing or the like, including a sleeve secured to said deleaver and opening into said chute, a stub shaft slidably received in said sleeve for limited axial movement therein, and a pivot connecting said stub shaft to said carbon turning bar.
Claim 6
Dependent Claim
153 words
A deleaver for separating superimposed plies of stationery and interleaved carbon plies of a continuous business forms assembly including at least one chute for receiving at least one stationery ply of the continuous business forms assembly, a powered carbon take-up reel associated with the chute for removing a carbon ply adjacent said one stationery ply from said one stationary ply, a carbon turning bar in said chute about which said carbon ply may be trained and directed to said carbon take-up reel, and means substantially permanently affixing one end of said carbon turning bar to said deleaver so as to prevent removal of said carbon turning bar from said deleaver except for servicing or the like, including a sleeve secured to said deleaver and opening into said chute, a stub shaft slidably received in said sleeve for limited axial movement therein, and a pivot connecting said stub shaft to said carbon turning bar.
Claim 7
Dependent Claim
28 words
The deleaver of claim 3 wherein said sleeve includes a longitudinal closed ended slot and further including a pin in said slot and secured to said stub shaft.
