Patent GB-643364-A (GB)
Abstract: 643,364. Totalizators; indicating-apparatus. TOTALISATORS, Ltd. (Automatic Totalisators, Ltd.). Oct. 16, 1947, No. 27722. [Classes 106 (i) and 106 (iv)] The odds units in a race totalizator system each comprise two sliders movable at right angles to one another in accordance with the grand total and the corresponding competitor total respectively, a computer lever fulcrumed on the first of said sliders and bearing against the other, an odds indicator controlled by said lever and a lost-motion device in the means which transmit movement to said grand-total slider. The grand-total slider 8, Fig. 2, is urged upwardly along a vertical rod 6 by a weight 16 on one end of a chain 17 which passes over a sprocket-wheel 18 on a line shaft 20 and which is at its other end fixed to the slider 8. The competitor slider 7 is urged to the left along a horizontal rod 5 by a weight 13 connected thereto by a cable 10. The shaft 20 is rotated, as described later, in accordance with the accumulation of bets in the grand-total adding unit. The movement of the slider 7 is controlled by a sprocket chain 14 connected thereto and co-operating with a sprocket-wheel (not shown) rotated in accordance with the accumulation of bets placed on the particular competitor to which the unit corresponds. The slider 8 carries a pivoted lever blade 25 and its counterweight 24 which constantly urges the face 26 of the blade 25 against the inside face of a shoe 23 pivoted on a pin 22 carried by the slider 7. The angular position of the rod 25 is indicative of the " odds " for the particular competitor and movement of this lever is' transmitted by a cable 30 to an indicator (not shown). The cable 30 is adjustably anchored at 31, stretches upwards over a pulley 27 carried by the slider 8, round a pulley 29 carried by the weight 24 and then under a pulley 28 also carried by the slider 8. The drive from the grand-total adding unit to the shaft 20 includes a lost-motion device comprising a driven disc 40, Fig. 3, keyed to the shaft 20 and having a lug 42 projecting into the path of two stop screws 37 in blocks 36 on a drive sprocket 35 rotated by a chain from the grand-total adding unit. The arrangement is such that there is an initial idle rotation of the sprocket-wheel 35 for the angular distance between the two stops 36 before it drives through the plate 40 the line shaft 20, thus allowing the zero position of the slider 8 to be above the point 9. A screw 43 on the slider 8 abuts a bracket 44 when the slider is in its zero position and the shoe 23 always restrains the blade 25 from moving clockwise.

Abstract: 722,697. Turning-gear. BENDIX AVIATION CORPORATION. July 14, 1953 [July 16, 1952], No. 19533/53. Class 7 (5). In an engine starter drive comprising a shaft 1 having a socket 2 at one end for the starting motor shaft 3 and a smooth reduced extension 11 forming a shoulder 12, a driving anchorplate 8 fixed on the socket 2, a second anchorplate 13 slidably and rotatably mounted upon the extension 11, a drive spring 15 connecting the plates 8 and 13, a screwshaft 18 slidably journalled on the extension 11 and having an overrunning clutch connection 19, 21 to the second plate 13, and a pinion 25 threaded upon the screw-shaft for movement into and out of mesh with an engine gear 26, a stop member 22 is provided on the extension to define the operative position of the pinion 25. A ring 14 on the extension 11, normally maintains the spring 15 under an initial compression whilst the clutch teeth 19, 21 are yieldingly held in engagement by a spring 23 located between the stop member 22 and the outer end of the screwshaft. The pinion 25 incorporates a spring- loaded centrifugally-retractable detent 27 that engages either of two shoulders 32 or 33 on the screwshaft, shoulder 32 preventing rebound of the pinion, and shoulder 33 stopping withdrawal of the pinion from the engine gear 26 until the engine is self-operative.

Title: Improvements in and relating to punch assemblies
IPC: B21D28/34
Filed: 1979-08-23
Abstract: The present invention relates to a punch assembly for use in a punching machine and comprising a punch, and a punch holder which are releasably engageable. As shown the punch (2) is provided with a first projection (5) the axis of which is spaced from the axis of the assembly, and a T-section projection (6). The first projection (5) is received in a recess (10) in the punch holder by relative axial movement of the punch and punch holder, and the projection (6) is received in an arcuate slot (11) which opens at at least one edge of the punch holder. When the projections (5, 6) are engaged in the recess (10) and slot (11), the punch and punch holder are received in a guide (13) which maintains the the punch and punch holder aligned. By virtue of the interengagement of the punch and punch holder the punch is prevented from rotating relative to the punch holder and therefore its orientation relative to the punch holder is determined. <IMAGE>
