Patent GB-445572-A (GB)
Abstract: 445,572. Calculating-apparatus. BURROUGHS ADDING MACHINE CO., 6071, 2nd Boulevard, Detroit, Michigan, U.S.A. Oct. 12, 1934, No. 29239. Convention date, Oct. 13, 1933. [Class 106 (i)] In a machine having a plurality of totalizers and a travelling paper carriage, means are provided for automatically and variably selecting the totalizers in predetermined columnar positions of the paper carriage in either direction of its movement. The invention is shown applied to a Hopkins machine of the type described in Specifications 18058/07, 18320/08, 18321/08 and 18322 /08, [all in Class 108]. In the machine shown in Figs. 1 and 2, the front register 16 is divided into sections forming six totalizers R1 ... R6 supported by a frame 23 all slidably mounted on a shaft 20 carried by pivoted arms 21. The frame 23 is constantly urged to the left by a spring 27 and is controlled in a step-by-step manner by an escapement pawl 33 and co-operating stop bar 30. The oscillating movement of the pawl 33 to free lugs 31 or 32 on the stop bar 30 is derived from the travelling paper carriage 18 which is itself under the control of the usual escapement mechanism. For this purpose release dogs 36 adjustably mounted on the carriage bar 37 coact with a pass-by pawl 38 carried by a frame 39 pivoted to the pawl 33, so that the totalizer frame 23 moves a section each time a release dog engages the pawl 38. The paper carriage can be returned manually or by power means in the known manner. In accordance with the invention an independent restoring means is provided for the totalizer frame which enables the frame to be moved to various register positions without regard to the location of the paper carriage. For this purpose the frame 23, Figs. 1, 2 and 4, has a forwardly extending arm 45 with a stud 46 engaging a slot in a pivoted arm 48. To the pivoted end of the arm is secured a toothed sector 52 with which is adapted to co-operate a pawl 53 pivoted on a lever 56 on the axis of the arm 48. The lever 56 is slotted to engage a pin 57 on a vertical slide 58. When the slide 58 is freed it rises under the action of spring 59 and the pawl 53 in moving away from the disengaging shoulder 61 engages the sector 52 which rocks the arm 48 to restore the totalizer frame. The slide 58 is restored during each machine operation by the engagement of a roller 67 on an arm 68 of the main shaft 72 with a projection 69 on the slide. The slide is normally hold by a latch 75 which is placed under the control of the paper carriage. A release pawl 80 adjustably secured to the carriage bar 37 co-operates with a stud 82 on a vertical link 83, the lower end of which has an extension 88 embracing a clutch member 89 slidably mounted on the shaft 91 of the known carriage return mechanism. When the release pawl 80 lowers the link 83 the clutch member 89 is coupled to the shaft 91 and is thereby rotated to cause its cam surface 93 to rock an arm 96 on the shaft 76 that carries the pawl 75. The release of the pawl 75 allows the slide 58 to rise to restore the totalizer frame. A latch 100 is provided to retain the link 83 in its lowered position until the latch 75 is withdrawn, whereupon a finger 103 on the latch releases the latch 100. Means are provided to stop the restoring movement in desired intermediate positions ; for the purpose of stopping the frame in the R2 and R3 positions, two arms 110, 110a, Figs. 1 and 2, are mounted on a post 111 at different heights, and each is provided at its end with a pass-by pawl 112, 112a, which project into the path of movement of the arm 48. During the movement of the totalizer frame from right to left, the arm 48 merely rocks the pawls 112, 112a in passing, but when the frame is being restored, the arm 48 encounters the pawls and causes their arms 110, 110a to swing unless such swinging movement is prevented. To prevent this movement, corresponding blocks 114, 114a, with projections extending rearwardly into the path of the arms 110, 110a, are adjustably mounted on the carriage bar 37. To arrest the frame in any other intermediate positions, additional arms and blocks will be provided. If it is desired to return the paper carriage to an intermediate position, column stops 120 and a release block co-operate in a known manner to arrest the return movement. Total taking mechanism. With the paper carriage in a particular column and the totalizer frame in the normal position, a total may be taken from the R1 totalizer. By depressing a button 125 a linkage is operated to rock the lever 39 and permit a step movement of the totalizer frame to enable a total to be taken therefrom. Repeated depression of the button 125 will bring any desired totalizer to total taking position. U.S.A.
