Title: Accounting or similar calculating machine
IPC: H01H37/00
Filed: 1955-04-13
Abstract: 768,507. Calculating-apparatus. NATIONAL CASH REGISTER CO. April 13, 1955 [May 18, 1954], No. 10591/55. Class 106 (1). In a calculating machine which performs two cycles of operation for total and sub-total taking, the line-spacing mechanism for the record material is normally blocked by a device which is moved from blocking position by the main operating mechanism during itementering cycles and during the second cycles only of total and sub-total operations. The line-spacing bail (not shown) is actuated by a roller 15 on an arm 13 which, after following a stud 12 in an arm on an oscillating drive shaft 10, is restored to effect line-spacing. A notch in the arm 13 is normally engaged by a plate 19, Fig. 2, but this plate is rocked to ineffective position during item-entering cycles by a connection 44, 42, 39 to an arm 29 rocked by a lever 26 controlled by a stud 33 in a link 22 reciprocated during each cycle. The lever 26 enters a notch 35 in a total slide 36 to block movement thereof. On depression of either the total or sub-total key however the total slide 36 is depressed and blocks the lever 26 which is thus prevented from moving the blocking plate 19. During the second half of the first cycle of a total or sub-total operation, a powered link 51 moves a total control link 54 to the right, Fig. 3, as described in Specification 732,760, and the link remains in that position during the line-spacing point in the second cycle. The link 54 is connected to rock a shaft 68 carrying an arm 69 in turn connected to the arm 29 which thus holds the blocking plate ineffective to permit line-spacing during the second cycle.

Title: Cushioning Devices for Presses.
Inventor: JEAVONS DANIEL
IPC: B21D24/02
Filed: 1967-03-07
Abstract: 1,175,994. Fluid springs and dashpots. TAYLOR & CHALLEN Ltd. 26 April, 1968 [7 March, 1967], No. 10637/67. Heading F2S. [Also in Division B3] The bottom die or platten 3 of a deepdrawing press is mounted on a die cushion which takes the form of a piston and cylindertype hydropneumatic shock absorber in which liquid is displaced by the piston 1 from the cylinder 2 to a reservoir 7 in which it is loaded by compressed gas in direct contact with the liquid. There are two flow paths between the cylinder and reservoir, one effective on inward and the other on outward movement of the piston. When the piston 1 descends a non-return valve 14 at the base of the cylinder 2 is closed but a passage (not shown) which is generally tangential to the cylinder walls contains a poppet valve 5, Fig. 2 (not shown), which allows a restricted flow of liquid to a conduit 6 leading to the reservoir 7. This valve is biased either by a coil spring whose loading is adjustable by rotating a screw 12, or by compressed air connected to a variable pressure source. On the return stroke valve 14 opens, normally to allow a substantially unimpeded flow of liquid by way of a tube 13 back to the cylinder. However, the return flow may be slightly throttled, by suitable design of the valve 14; and, at will, it may be completely stopped by closing the bottom of the tube 13 by means of a poppet valve 16, this being controlled by a Bowden cable 22. Such control allows the die or platten 3 to be stopped, e.g. to permit adjustment of the press. Alternatively, the valve 16 may be closed and then re-opened after each descent of the piston, to provide a predetermined delay in piston return. For this purpose the Bowden cable may be replaced by an hydraulical control system operated automatically by the press itself. Any liquid which leaks past the piston in use returns to the cylinder via valve 15, and any gas which escapes from the reservoir 7 will eventually accumulate beneath the removable plug 24.
