Abstract

638,761. Band clips. BENDIX AVIATION CORPORATION. Oct. 7, 1947, No. 26955. Convention date, Oct. 17, 1946. [Class 44] [Also in Groups XXIII and XXVII] A starter (see Group XXVII) is secured to its engine by an adaptor 17, Fig. 1, comprising a flange 18, attached by bolts 66 to the engine crankcase 10, and a conical flange 19; the two flanges being joined by a tubular portion 68 that has axial troughs in its periphery to enable bolts 66 to be placed in position. A conical flange 26 on the starter 20 and the flange 19 are clamped together by the ring 38 which is of channel section. The two adjoining ends 48, 50, Fig. 2, of links 42 and 46 respectively, are secured by a yoke 55, the end 48 embodying a through pin 56 upon which is pivoted the yoke 55, the closed end having a bolt 58 screwed therein that enters a depression in the end 50 to tighten up or release the ring and hence the starter. Pins 64 secured to the flange 19 and fitting into holes in the flange 26 relieve the ring of the effects of the torque exerted by the starter. In a modification, the adaptor is integral with the crank casing whilst some of the pins 64 may be secured to each flange 19 and 26, as there may be any number of pin holes to permit of mounting the starter about its axis in any one of a number of selected positions. In another modification, an arcuately slotted straight or curved member is pivotally mounted on one end of the ring and a headed pin is fixed on the other ring end sliding in the slot of the arcuate member so that the ring is entirely closed though still capable of expansion. More than one ring may be used and the additional rings may secure to the engine such accessories as generator, fuel and vacuum pumps, carburettor, governor and supercharger.
