Abstract
498,224. Resilient mountings. AUBAREDE, P. C. A. M. D'. June 1, 1937, Nos. 15173 and 15174. Convention dates, June 9, 1936 and Dec. 16, 1936. [Class 108 (iii)] [Also in Groups XXXIII and XXIV] A resilientlymounted engine &c. is coupled to a member (such as an air. screw) having a high inertia rotating at high speed by means of a universal transmission joint whereby the gyroscopic action of the airscrew is not transmitted to the engine shaft. In Fig. 6 the engine 1 is supported at its front end 4 by a rubber sleeve 3 and at its rear end by two discs 55 attached to a central disc 54 on the frame 6 by rubber blocks 53 and a rubber ring 57 to limit the amplitude of the oscillations. The propeller 2 is mounted in the frame by ballbearings 62 and is attached to the engine shaft through a rubber ring 60. The front part of the engine may be supported by a vertically arranged rubber sleeve which is offset from the axial plane of the engine and the propeller may be driven through an intermediate shaft having rubber discs between the flanges. In Fig. 7 the engine is mounted on the frame by a ring of rubber blocks 50, each block 50, Fig. 8, being attached to internal and external rings 51, 52 attached to the engine casing 1 and circular flanged rings 49 attached to the frame 6. A single block of rubber 50 and a single channelshaped ring with flared flanges may be used. The front part of the engine shaft, Fig. 7, is provided with a flanged disc 47 which drives another flanged disc 46 on the propeller shaft through a rubber ring 48, the propeller being of the variable pitch type and the shaft being supported in ball-bearings 43. In Fig. 10 the engine crankshaft is supported in a rubber bush 37 in a hollow sleeve 38 supported in ballbearings on the frame 6 and carrying the propeller 2, the drive being transmitted through a disc 41 and rubber blocks 42. In a modification the disc 41 drives the propeller through a single ring of rubber having staggered metal rings embedded therein. In Fig. 13 the front part of the engine is supported on a rubber ring 3 having metal rings embedded therein and the propeller is supported on the crankshaft by a rubber bush 37 with metal discs 73, which may be arranged axially, the engine drive being transmitted through a disc 41 and rubber pads 42 attached to lugs 43 on the propeller boss, pads 44 on the disc 41 are fitted to absorb movement of the propeller on the shaft. The disc 41 may be placed on the other side of the propeller. Specification 478,868 is referred to. The Specification as open to inspection under Sect. 91 described an end support for the engine comprising two opposed verticallyarranged leaf springs having their ends supported in rubber blocks and engaging at their mid-length with a projection from the engine casing. The end may be suspended by flexible members or may rest on rubber pads, the front of the engine being supported in rubber bushes and the propeller connected directly to the crankshaft. Other modifications show a streamlined extension of the engine fixed to the engine and supported at the end by a rubber sleeve, the front bearing of the engine being supported by a rubber disc ; or the engine,is supported in a streamlined casing by a ring of rubber blocks, stays from the engine being supported in a rubber bush in the nose of the streamlined casing. This subject-matter does not appear in the Specification as accepted but is contained in Specifications 500,252 and 500,538.
