Title: Improvements in or relating to dispensing apparatus for cloth or other material
IPC: B65H35/00
Filed: 1959-01-23
Abstract: 872,682. Measuring continuous lengths; recording-apparatus. REFLECT ONE CORPORATION. Jan. 23, 1959 [Jan. 27, 1958], No. 2557/59. Classes 106 (2) and 106 (4). Apparatus for dispensing cloth &c. from bulk and measuring the quantity dispensed has means for receiving a record blank and marking it in dependence upon the quantity dispensed and interlocking means adapted to preclude dispensing except when a record blank is in, correct record-receiving position. Cloth 23, Fig. 2, being dispensed from a bolt is drawn manually between rollers 24, 25, the latter being spring-mounted and connected to a 2-way switch 29 which is sensitive to the presence of cloth between the rollers. Rotation of roller 24 drives a pointer 22 indicating on a dial 34 the length of cloth fed. Roller 24 also drives a shaft 41 which is threaded at 42, Fig. 3, causing a carriage 43 to move to the left along a graduated tabulating record card 49 positioned between guides 51, 52 with its right-hand end against a stop 53 advanced to position A. When the required length of cloth has been measured it is cut and removed from between rollers 24, 25. This actuates switch 29 causing a punch 62 on carriage 43 to descend and notch card 49; a motor 68, Fig. 2, is also energized to drive pointer 22 and carriage 43 back to their initial positions, with the carriage in position C, Fig. 3, during which movement a knife edge on the punch cuts card 49 leaving an elongated notch Z. The card 49 is associated with its particular bolt of cloth and when it is reinserted in the machine at a subsequent measuring operation the notch ensures that the record will start where the previous cutting stopped so that the card will indicate the balance of cloth left on the bolt. When stop 53 is in the advanced .position A, a pawl 48 engages a star wheel 47 on shaft 41 to prevent rotation of the shaft. Stop 53 is under the control of a solenoid 61 and is retracted, to permit measuring, only when switch 29 has been closed by the insertion of cloth between rollers 24, 25 and a switch 54, Fig. 3, has been closed by insertion of a card 49. In a modification, the card, instead of being notched, is marked by a stylus with a stripe of coloured, magnetic or conductive ink; to position the card for a measuring operation, the end of the existing stripe is sensed by photo-electric, magnetic or electrically conductive means. In a further modification, the card is given a perforation to indicate the length of cloth, the perforation being subsequently sensed by mechanical or electrical means for re-positioning the card in the apparatus for a subsequent dispensing operation.

[Class 112] A circular cutter is mounted so that it can be swung out of its operative position and is actuated by a pitman and clutch. In one modification the cutter 28 is carried by arm 21 which is rotatably mounted on an eccentric sleeve 18. The cutter is actuated by a pitman 44 which is connected to the main shaft and to a roller clutch 39. In the operative position the arm 21 is secured to the work plate by a screw 52. In a variation the arm 21 is mounted on a bracket bolted to the work plate and is driven by a pibman 153, segmental lever 148 and a rod 138. The cutter is maintained in its operative position by a flat or spiral spring 66 the pressure of which can be varied. Further variation of the pressure is obtained by a treadle operated bell-crank lever 168, 176. When the lever is depressed to its full extent the cutter is maintained in the inoperative position by a roller 177 which moves beneath the fulcrum. Feeding work.-To enable the cutter to assist in feeding the work, a cylindrical member 69 is mounted on the hook shaft 3 to rotate freely with the cutter. A differential movement between the cutter and the four-motion feed dog is provided by adjusting the driving link 138 of the cutter. The link 138 is connected to a treadle 148F and to a slotted segmental lever 148. Normally the link 138 lies at the extremity 148B of the slot, but when it is desired to reduce the movement of the cutter the link is pulled down the slot by the treadle.
