Abstract: 123,725. Noonan, J. J. Feb. 26, 1918, [Convention date]. Counters affording several rates of actuation.- A cloth-measuring machine comprises means whereby the length of cloth drawn off from a roll is indicated at a sight opening together with the cost at a selected price. Permanent records are made for delivery to the customer and for retention in the machine, and the edge of the cloth is slit on the operation of an external handle to return, the counting, indicating, and associated parts to the zero position. The cloth passes over a roller C, Fig. 5, and between it and a pressure roller D carried by an arm 2 pivoted at 3 to the casing. Driven by toothed gearing from the shaft 1 of the roller C is a shaft 4 on which is secured a disk E showing fractions of a yard on its periphery, motion being communicated to a second disk F showing yards by transfer mechanism. The price per yard is shown by a disk G supported on a bearing co-axial with the shaft 4, the disk being set by a hand-operated shaft 9, Fig. 3, through a pinion 11 thereon engaging teeth 12 on the indicating disk. Totalizing counter wheels H, I, J are driven from the shaft 4 through a number of differently toothed segments 19, Figs. 3 and 5, carried by a drum K and adapted to be engaged by an adjustable pinion L mounted to slide on and rotate with a shaft 13 which drives through replaceable gearing a wheel 18 connected to the units disk H. Movement of the pinion L is effected by the setting of the disk G through a pinion 26 on the shaft 9 reciprocating a rack 24 connected to a carriage 22 in which the pinion L is mounted. The pinion is locked in the set position by a second, slightly larger pinion L', secured thereto, the teeth of which bear on the edge of one of the spacing rings formed on the drum K between the toothed segments. Grooves 20 formed at the side of the teeth 19 allow the pinion L to be driven when the teeth come into engagement. Transfer mechanism from the fractions wheel to the yards wheels F comprises a disk 28 secured to the shaft 4 and provided with a notch 32<a> and teeth 32, Fig. 11, engaging a half-leaved pinion 30 connecting the disk to a toothed wheel 29 fixed to the shaft 4 and frictionally connected to the yards wheel F by a spring 29<c>, Fig. 4, the disk F being loose on the hub of the wheel 29. Recording-apparatus.-Formed on the various indicating disks are printing type z adapted to print on two record strips P, S when a platen M, Fig. 9, is raised, the record on the sales strip S being detached. Movement of the platen is effected when a projection 43<a> carried by an arm 43 of the platen-supporting frame is struck by a projection 44 on a hand-operated clearing shaft R during the first part of its revolution, the roll P<2> being advanced by a link 48 connecting the platen to a pawl-bearing lever 47. Zeroizing-mechanism.-Operation of the resetting shaft R to clear the machine causes a part 49a of a cam thereon to move a frame 51 so that the driving pinion of the units disk and the transfer pinions 53 are moved out of engagement, a bar 54, Fig. 9, serving to hold them in correct alinement when lowered. A second portion 49<b> serves to return the frame to its original position. Rotation is imparted to the hundreds disk J by a sector 60 on the shaft R engaging lateral pins 61 on a wheel 62 which drives a pinion 63 secured to the disk, similar devices being provided for the drum K. The wheels 18, Fig. 3, of the units and tens disks H, I are engaged by pinions 70, 71 with laterally projecting pins 70<a>, 71<a> with which co-operate sectors 70b, 71b. Slitting edge of cloth. A knife 72, Fig. 5, carried by a spring-retracted arms 72<a> is lowered to cut the edge of the cloth by a cam carried on the shaft R. Locking-devices. Means are provided for locking the drum and associated parts against rotation at times other than when cloth is being measured and also for locking the shaft R after one revolution has been completed. These means comprise a tooth 78<a> on a spring-retracted lever 78, Fig. 5, engaging a notch 79 in the drum K and a pawl 80 adapted to enter a groove 81 in a disk 82 on the shaft R. The lever 78 is operated by an inclined block 83 on a lever 84 which is pivoted to the casing and engages the similarly shaped end of the lever. At its inner end the lever 84 is connected by a link 88 to the arm 2 carrying the pressure roller D, the link being connected by a spring to the casing. In the position of the parts shown in Fig. 5, the lever 78 is in the locking position and is held therein by the part 83, the rolls C, D being separated. In operation, after the insertion of the cloth between the rolls, a finger piece on the lever 84 is depressed, thus raising the piece 83 from the lever 78, breaking the toggle 88, 84 and allowing the spring 91 to withdraw the projection 79. Simultaneously, a pin 90 on the lever 84 is withdrawn from the pawl 80, thus freeing the shaft R. After the required length of cloth has been withdrawn, the clearing shaft R is rotated, a cam 92 thereon forces the projection 79 into one of a series of justifying notches 79<a>, the knife is operated and the platen raised to make the record. The drums K and disks E, F are then returned to zero by the arcs 60, and a cam 86 strikes a projection 85 and straightens the toggle to separate the rolls C, D, the movement of the lever 84 so produced forcing the projection 79 into locking position. The totalizing counter wheels are returned by the final part of the movement of the shaft R which is then locked by the pawl 80.
