Abstract: 18,269. Flanigan, J. J. Aug. 2. Feeding, winding, and registering webs.- Relates to a machine for copying departmental orders from a single master order sheet such as A, Fig. 19, each departmental order having the same heading or " caption " A<1> but only a portion of the body part A<2> of the sheet such as one of the prepared groups of items K, Y, S, &c. The machine is provided with two duplicating-bands extending between let-off and takeup rolls and having their working surfaces in alinement, the bands carrying the caption and item matter respectively of the master sheet. The item band is advanced step-by-step to bring successive groups of items into alinement with the caption, the band of which can be moved as required to bring a fresh caption of a different master sheet into position. In each position, a departmental order is obtained on a sheet carried by a cylinder which is rolled over the bands. Figs. 2 and 3 are elevational and plan views of the machine, and Fig. 6 an inside view of one of the side frames. The item and caption bands 13, 14 pass over guide-rollers 11, 12 arranged between receiving and delivery spools, each mounted at one end in rotary chucks 25, 26, 27, 28, Fig. 6, and at the other end in spring-controlled pivoted arms 21, Fig. 18<a>, so as to be readily detachable. The ends of the spools are identical to render them interchangeable end for end, and each is provided with rectangular and circular portions to fit the chucks and arms 21 respectively. The chuck 26, Fig. 6, of the receiving-spool of the item band is under winding tension by a spiral spring upon a shaft 31 acting through gearwheels 36, 38, 39. Unwinding of the spring when the spool is removed is prevented by the engagement of a spring-pressed dog 43 with one of a series of holes 42 in the wheel 38, the dog being normally held inoperative by the engagement therewith of the end of the spool. The receiving-spool of the caption band is similarly kept in winding tension by a spring on a shaft 49 acting through gearing 51, 52, and a similar locking-dog 55 is provided. The item band is advanced by means of a sliding rack bar 64 carrying a band-clamping-device and actuated by a spur-wheel 117 loosely mounted upon a shaft 118 and driven by a spiral spring. The manual retraction of the bar 64 rewinds the driving- spring, and also rewinds the tensioning-spring of the band-receiving spool through the medium of a friction disk 119 and ratchet and spur gearing 120, 122, 123. The band-clamping device comprises a plate 65, Fig. 3, carrying hinged clamping-plates 70,71 connected together so as to be operated simultaneously on depressing a handle 72 fixed to the plate 70. One end of the plate 65 is fixed to the bar 64, and the other end is slidably supported upon the machine frame. The caption band is gripped by a similar clamp 146, but the handle end is slidably mounted upon a slotted graduated guide 148 fixed to the machine frame. The travel of the clamp is limited by the end of the slot in the guide, and by a stop 149, Fig. 2, carried by a bar 150 slidably mounted between the guide 148 and a similarly graduated slotted scale bar 151 on the machine frame. The bar 150 may be clamped to the scale 151 by a screw 152. To prevent winding of the bands when the clamps are released each delivery spool is provided with a ratchet-wheel 153, Fig. 6, and retaining-pawl 154, which is normally held inoperative by means of a finger 156 on a pivoted bar 157, which is rocked by the opening of the clamp, thereby releasing the pawl. To prevent mistakes in using the machine, the retraction of the rack-bar 64 before the clamp of the caption band is released is prevented by a pawl 161 normally engaging the rack and controlled by a spring 164. The pawl is released in opening the clamp 146 by means of a lever 165, which is actuated by the rocking of the bar 157<a>, the pawl being kept in its released position by the engagement of the end 164<b> of the spring 164 with the inclined face 163<b> of the pawl. The pawl is returned to normal position during the retraction of the bar by the engagement of a finger 169 on the bar 64 with a spring 170 on the pawl. The pawl may be rendered inoperative by the engagement of a hand-actuated sliding pin 239 with a notch 161<a> on the pawl. The delivery spool of the item band is provided with an automatic band-tensioning device comprising a ratchet-wheel 153 and a pawl 186 carried by a spring-controlled pivoted arm 183. Each band-receiving spool is also provided with a ratchet tensioning-device operated by fingerlevers 189, 189<a>. The advance movement of the item band is controlled and limited by means of a series of vertically sliding stop-pins 84, Figs. 3 and 10, carried by the bar 64 and having their upper ends normally flush with the surface of the bar but capable of being projected above the bar hy a finger-lever 98 mounted upon a carrier 90 slidable upon a shaft 89. The foremost pin 84<a> normally projects above the bar and, when the bar is fully retracted, contacts a fixed bracket 112 carrying a pin-depressing lever 131. The depression of the pin 84<a> permits the bar 64 to advance under the action of its spring until the next-raised stop-pin 84 contacts the bracket 112. The carrier 90 is carried forward with the bar by the engagement of the raised pin with a pawl 108 on the carrier until the pawl is released by contact with a pin 111 on the bracket 112, allowing the carrier to be retracted by a tape 104 under the influence of a spring 106 until the pawl 108 contacts the next raised pin 84. Delivery apparatus. - The hollow copying- cylinder 201, Figs. 2 and 3, is loosely mounted upon a spindle 198, one end of which is supported in a frame 197 slidably and pivotally mounted upon a shaft 193 and the other end in an upwardly bent arm 211 of a transverse bar 210 carried by the frame 197 and supporting a sheet feeding and delivery chute 212 which ends, at the side adjacent the cylinder, in a curved lip to guide the sheet into a gripper bar 201<b> and also to assist in the delivery of the sheet. The cylinder is operated by the handle 200 of a bail 199 loosely mounted on the spindle 198 and provided with a band 235 partially surrounding the cylinder to guide the sheets during delivery on to the chute 212.
