Title: Improvements in slide rules and like calculating apparatus
IPC: G06G1/08
Filed: 1924-06-23
Abstract: 233,183. Fairbrother, H., (Wichmann Geb.). June 23, 1924. Adding and subtracting apparatus; slide-rules. -A slide-rule or other scalar calculator consists of a rotatable graduated prism mounted in juxtaposition to a sliding plate bearing sections of a logarithmic or other scale corresponding with similar sections on the faces of the prism, a cursor common to both scales being provided. In the form shown in Figs. 1 and 2, the logarithmic scale for the numbers 1-10 is arranged in six sections upon a hexagonal prism 2 rotatably mounted in a casing 1 near the uppermost of three slidable plates 8, 9, 10 that are interchangeable and are graduated with logarithmic scales for the cardinal numbers, their reciprocals, squares, and cubes, and for sine and tangent values. A glass sheet 14 provided with a hair line serving as a cursor is slidably mounted and covers the prism and plates. The plates have index numbers a on the left and right to correspond with similar numbers on the prism for ensuring reading of the correct scale on the latter. The adjustment of the prism may be effected by means of a knob 5 and numeral wheel 6 or mechanical means may be used. Thus, referring to Figs. 3 and 4, two perforated bands 70, 71 pass around sprocket wheels 68, 69, 73, 74, the latter two being attached to the shaft of the prism. The sliding of the graduated plate one way or the other will cover one band and expose the other, which may then be moved by a stylus in one direction or the other to turn the prism to an extent dependent upon the scale section in use. In another construction, the bands are replaced by racks connected by ratchet mechanism with the prism shaft, the arrangement being such that the exposed rack is always to be moved downwards by the stylus and rotates the prism in one direction or the other according to the position of slidable gear wheels adjusted for multiplying or dividing. In the form shown in Fig. 11, the graduated plate 25 is shifted to the right or left by a fine adjustment 43, 44, 45, and behind it is a fixed plate 28 bearing near its ends index or limit numbers opposite the corresponding scale sections. Stepped rollers 29, 30 are engaged by wheels 35, 36, the carriers of which are positioned along the index numbers so that when a handle 52 is given one rotation a corresponding rotary movement is imparted to the prism 19 to expose the required scale section. To indicate the number of integers in the result, a numbered wheel 64 is first set in accordance with a rule given in the Specification, and is automatically rotated one step per complete rotation of the prism by means of a single toothed disc 62 co-operating with a pinion 63. This form of the invention may be used for ordinarv addition and subtraction, the wheel 64 being then arranged at the left and used to denote numbers in the denomination next above the highest on the scales.

Patent GB-235591-A (GB)
Title: Improvements in automatic machine guns
IPC: F41A3/10
Filed: 1924-12-08
Abstract: 235,591. Browning, J. M. Dec. 15, 1923, [Convention date]. Machine guns.- Relates to firing mechanism for automatic guns of the recoil-operated type adapted to fire large calibre shells and mainly intended for use on aircraft. The invention is more particularly concerned with the automatic gun described in Specification 226,197 in which a transversely-sliding wedge breech-block is actuated by the longitudinal reciprocations of the lock-frame. According to the present invention, the lock-frame is mounted at the rear of the breech-block and is provided with a spring- pressed hammer which is automatically cocked on the recoil of the lock-frame by a cocking-lever mounted on the frame and operated by the breech-block actuator which is also mounted on said frame. The drawing shows the barrel 7, barrel-extension 8, breech-block 10 and lockframe 12 in the firing position. On recoil, these parts move rearwards together against the action of a barrel recuperator-spring 9 and a lock-frame return spring 17. The breech-block is lowered in guides on the barrel-extension by fixed cams which operate upon an actuating bell-crank lever 11 hinged at 11<a> to the lock-frame and carrying a stud 11<d> for engagement with a groove 10<c> in the block. The barrel and breech-block return alone to forward position, the lock-frame being retained whilst a cartridge is being lowered between the recoil plates of the barrel-extension. When the lock-frame moves forwards to load a cartridge, the lever 11 engages the fixed cams to raise the breech-block, the last part of the closing movement being effected by momentum and by the reaction of a spring, and the pin 11<d> finally passing out of the slot 10<c>. The block is then wedged upwardly by an incline 11g on the .lever 11 and serves to fasten the lock-frame in forward position. The lost motion between the pin 11<d> and the slot 10<c> delays the opening movement of the breech-block and prevents rebound at the end of the closing movement. For hand actuation, a rearward pull on the lever 11 lowers the breech-block to enable the lock-frame to move rearwards without the barrel. The firing- mechanism, mounted on the lock-frame, comprises a firing-pin 13 and a hammer 20 cocked into engagement with a sear 21 by a cocking- lever 43 which, during the breech-opening movement, is engaged by a projection 44 on the lever 11. The sear is released by a trigger-lever 25 which engage.s with a longitudinally-sliding trigger-bar 34 actuated by a pivoted hand-trigger 35. The trigger-lever 25 actuates the sear through a pivoted connector 28 which engages a trip-lever 29 the forward end of which is rocked by the closing movement of the lever 11. This prevents operation of the sear unless the breech is closed. For automatic firing, the trigger-bar 34 is kept pulled and the firing is effected by the engagement of the lever 11 with the trip-lever 29. The cartridge-feed mechanism is that described in Specification 235,592.
