Title: Improvements in or relating to power transmission clutches
IPC: F16D43/202
Filed: 1919-04-16
Abstract: 140,234. Aurand, F. E. April 16, 1919. Clutches, claw.- In clutches of the kind adapted to disengage automatically under excessive load for driving mining, washing, and tapping machines &c., a spring - pressed lever r normally engaging projections on the driving and driven parts is both rotated and moved longitudinally in being pressed to the declutching position. The driving-shaft 10 is secured to a hub 7 provided with a flange 6, on pivots 18 on which turn links 17 supporting levers 14 which normally engage at one end with lugs 12 on the driven member 1 and at the other end with notches 29 in the hub 7, being retained in position by adjustable spring-pressed plungers 21 pivoted to the levers by pins 23 and rocking in recesses 24 in lugs 25 on the flange 6. When excessive load occurs, the levers 14 are pressed aside by the lugs 12 against the action of the plungers 21, and the lever ends are forced into second notches 30 in the hub 7, the plungers acting to prevent their escape. Counterweights 34 on the links 17 balance centrifugal action. The parts are returned to clutching position by rotating by means of a spanner or the like a sleeve (not shown) on the shaft 10, which sleeve has slots engaging with the pins 23, so that the levers 14 may be lifted into the notches 29. Antifriction rollers are arranged within the notches 29. The notches &c. are duplicated so that the whole of the moving parts may be reversed for a reversal of drive. Fig. 6 shows an arrangement suitable for washing and other light machines in which it is desired, in order to avoid damage to the driving electric motor, that the parts may be especially sensitive to load during starting. In this case, the clutch lever 67 is extended beyond the shaft and carries a centrifugal weight 68 which increases the pressure between the lever and its notch 62 during normal speed of drive. An external knob on the pin 65 connecting the lever 67 with its link 64 is hand-manipulated to restore the parts to position. Fig. 10 shows a construction suitable for tapping-machines, in which it is desired that the parts shall be reset by a reversal of the direction of drive. The clutch lever 92 has a lug 97 for engaging a lug 91 on the driven member 1, and is pivoted to a link 94 on a pin 95, on which is also pivoted a sleeve 104 with a lug 105 which engages the lug 91 for reverse drive. A lug 106 on the sleeve 104 engages a corresponding lug 107 on the lever 92, so that when the parts 91, 105 engage for reverse drive, the lever is lifted and its notch 100 re-engaged with the lug 101 on the driving-plate. A spring 108 secured to the sleeve 104 allows the lug 105 to pass the lug 91 during forward motion of the driving-shaft.
