Title: Safety torque driver
Inventor: BETTER BERNARD RAYMOND
IPC: F16D43/206
Filed: 1956-08-20
Abstract: 809,518. Drilling; tapping. SCULLYJONES & CO. Aug. 20, 1956, No. 25426/56. Class 83 (3). [Also in Group XXIV] A safe-torque clutch for screw-thread tapping or drilling comprises a driving-shell 10 having a degree of resilience with a conical-bore 12, a driven member 16 with a conical-end 17 spaced from the bore 12, and sets of rollers 13, 34 arranged between the two members. The rollers 34 are maintained in fixed positions relative to the driven part 17 by a cage 32, whilst the rollers 13 are held by a free-cage 29 which is acted upon by a spring- pressed drag-ring 28 so that when the drive is in the direction of the arrow, Fig. 3, the rollers 13 are moved into the wedge-driving position shown to transmit a torque from the driving to the driven member. At a predetermined safe-torque the rollers 13 will ride over the tops of the rollers 34 by deforming the shell 10 to break the drive. The rollers 13 are held in a drive-released position, intermediate the rollers 34, by balls 39 in longitudinal grooves 40 in the outer cage 29 co-operating with a control groove 38 in the inner cage 32. Reversal of the drive will drive the driven-member reversely unless the safe-torque is exceeded. If overriding does not occur in the reverse drive, the rollers 13 will be re-set ready for the forwarddrive, but if over-riding does occur then a resetting operation is necessary, which may be done manually. The driven-member is maintained in axial-relation to the driving-shell 10 by a screwed-sleeve 23, ball-bearing 21 and a locking sleeve 41. The screwed sleeve 23 can adjust the relative axial position of the shell 10 and driven-cone 17 to vary the safe-torque to be transmitted.

The wheels e.g. 34a, 36a, which are projectable through slots 44 in the side walls of the housing 16 are frictionally driven from the central wheel viz. 22a and are mounted on the ends of pivot arms 41. At each side of the housing the axles 38 of the frictionally driven wheels are connected by link bars 40 operable by pneumatic cylinders e.g. C1 to move the frictionally driven wheels from the rack driving positions to the inoperative positions. When a rack 18 engages a plunger PS1 of an electric switch S1 at a pooling station PS, the switch is operated to energize a solenoid which operates a pneumatic valve associated with the cylinder C1 to admit air to the cylinder to move the associated group of drive wheels 34a, 34b, 34c to their inoperative positions and thus the rack stops. Thereafter following racks are automatically stopped by operation of pneumatic valves and cylinders, all as described with reference to Figs. 9, 10 and 12 (not shown). An operator at the work station 20 associated with the switch S1 can cause the rack 18 stopped at the pooling station PS to be moved along the track to the work station 20 by energizing a photo-electric cell PC, Fig. 1, by a lightproducing means 64. The cell controls an electric circuit which de-energizes the previously mentioned solenoid to move drive wheels to their operative positions as described with reference to Fig. 11 (not shown). Racks 18 which are provided with castors 52, Fig. 4, are propelled around the ends of the housing 16 as described with reference to Fig. 6 (not shown).

Abstract: 926,463. Endless conveyers; slewing arm load-handling machines. REGIE NATIONALE DES USINES RENAULT. July 28, 1959 [Aug. 8, 1958], No. 25871/59. Classes 78 (1) and 78 (3). In a conveyer system comprising an endless train of carriers 1 running on rollers 2 in tracks 3 and connected by an endless chain, at each preselected pick-up or discharge station, a carriage mounted on rollers 8 in tracks 3 is coupled automatically to the appropriate moving carrier and is provided with means for transferring an article, such as a crankshaft 6, between supports 5 on the carrier 1 and a hook 15, mounted on a slewable jib arm at the station, while the carriage and carrier are coupled. As shown, the carriage is provided with fingers 16 which are movable to engage fingers 17 on the carrier by links 18, 20, 22 connected to a pneumatic ram 24. Forked supports 26 are movable vertically on the carriage by a pneumatic ram 27 which rotates a shaft 30 provided with pinions engaging racks on members 32. Each carriage, when disengaged from the carriers, is held against stops 14, Fig. 3, by a weight 10. The hook 15 is vertically movable by a ram 52, Fig. 6, on a bracket 49 which is pivoted about a shaft 50 on the jib arm 39 which is rotatable about a vertical post 36 by a ram 40 and cable 41. As the supports 26 and members 32 move vertically to receive a crank-shaft 6 from a hook 15, cams 75, 76 secured to the members 32 engage rods 72 which are slidably mounted on the carriage 1 and move them to a position associated with the station at which the crankshaft is to be removed. The rods have recesses which, if they are not aligned with cams 90, 91, 92, cause these cams to engage rockers 82, 83, 84 which operate selector switches 79, 80, 81 along the conveyer line, so that the positions of the rods determines the next station at which a crank-shaft is to be picked up from a carrier. As the crank-shaft is picked up, cams 73, 74 push the rods back to the resetting position so that the carrier can be loaded with a crank-shaft at the next station having all three cams 90, 91, 92 retracted. The switches 79, 80, 81 and a switch 70, determining the correct positioning of the jib arm 39, can co-operate in series in an electrical control circuit (not shown) which, when the control combination of the station in question is produced, brings into action electromagnetic distributers of air under pressure for individual control circuits for each of the rams 24, 27, 52.
