Abstract

1337776 Ratchet mechanisms AUGUST BILSTEIN 15 Sept 1971 [19 Sept 1970] 42991/71 Heading F2Q [Also in Division B8] A jack, Fig. 1, comprises a threaded spindle 15 carrying a load arm 23 and rotatable by a crank handle 16 with a hand grip 17 through a driving cog-wheel 11 and a spindle cog-wheel 10. The spindle 15 is mounted in a support column 13, the spindle cog-wheel 10 being attached to the spindle 15 and supported on a ball-bearing 21 carried by a plate 19 on the top of the support column 13. An arm 26 of the plate 19 carries a bolt 18 acting as a bearing shaft 12 for the driving cog-wheel 11 which is attached to the crank handle 16 for rotation therewith. Both the spindle cog-wheel 10 and the driving cog-wheel 11 are flat, toothed discs, with the bearing shaft 12 located below the spindle cog-wheel 10. Further cog-wheels (33), (32) Fig. 2 (not shown), may reinforce the cog-wheels 10, 11. In the modification shown in Figs. 9, 9a, spindle cog-wheel 10 is driven by a ratchet lever 40<SP>1</SP> with a bifurcated end shaving its two arms 511, 51<SP>11</SP> connected by a reinforcement bolt 52 and pivoted on bearing shaft S. A pair of driving cog-wheels 11<SP>1</SP>, 11<SP>11</SP> are respectively driven by pawls 41<SP>1</SP>, 41<SP>11</SP>. Each pawl 41<SP>1</SP>, 4111 is urged by a spring 531, 53<SP>11</SP> respectively into engagement with one of the driving cog-wheels, one, e.g. 41<SP>1</SP>, rotating the cog-wheel 11<SP>1</SP> whilst the other, 41<SP>11</SP> locks when the lever 40<SP>1</SP> is raised. On pushing down the lever 40<SP>1</SP>, pawl 41<SP>1</SP> locks whilst the other, 41<SP>11</SP>, drives the cog-wheel 11<SP>11</SP>. By operating the reversal lever 54 the direction of drive is reversed by changing over the pawls 41<SP>1</SP>, 41<SP>11</SP>.
