Abstract: 646,632. Variable speed gearing. LOCKHEED AIRCRAFT CORPORATION. April 27, 1945, No. 10728. Convention date, March 6, 1942. [Class 80(ii)], [Also in Groups XI, XII, XIII, XXVI, XXVIII and XXXIII] A gas turbine jet propulsion engine has the turbine coupled to the compressor or compressors through a differential gear transmission which allows the relative speeds of the turbine and compressor or compressors to be varied during operation. The gear shown, Fig. 11, is mounted between two compressors driven by a single turbine. The shaft 76 of one compressor is connected to a planetary drive spider 194 carrying six planetary pinions which mesh with a sun gear 201 keyed to the shaft 32 of the second compressor and a ring gear 203 mounted on the spider 194 by ball bearings 205 and 206. An extension 196 of the spider 194 is rotatable on the shaft 32 and has fixed on its end the fluid coupling impeller 199. The speed of one compressor relative to the other can be varied either by filling or emptying the hydraulic coupling or by increasing or decreasing the load on the auxiliary drive shafts 208, 388. The amount of oil in the hydraulic coupling is regulated by a needle valve 447, Fig. 19. controlled by bellows 439 which are responsive to the discharge pressure of one of the compressors. An arrangement in which the gearing is modified to make it suitable for driving a reciprocating compressor and its associated valve gear is also described.

Abstract: 454,940. Boot-making machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., RICKS, F., and BOOTHROYD, H., Belgrave Road, Leicester. April 9, 1935, No. 10898. [Class 17 (i)] Burnishing.-A burnishing-machine has a tool constructed and driven as described in Specification 426,563, for burnishing the top lift of a heel, and a second tool, for burnishing the edges of the heel breast flap, oscillated by connections with the oscillated shaft of the first tool. As described in the prior Specification, the top-lift burnisher 21 is driven by a rotating shaft continued as an aslant pin 9 passing through a sleeve 11 mounted to rock freely about its axis in a yoke member 15. Two aligned shafts 19, 35 are connected to the yoke, to be oscillated thereby. The first engages a long bearing 20, and the second is bored eccentrically to house a pin 39 to which is pivoted one end of a connecting rod 43 also engaging a pin 44 secured to an arm 33 which oscillates the shaft 27 of the breast flap burnisher 31. This burnisher is positioned some six inches to the rear and ten inches to the right of the first burnisher, so that an operator may present a shoe to the tools, in sequence, by a partial turn. The shaft 27 has a bifurcation at its end to engage an ear on a block 49, a clamping bolt 47 allowing angular adjustment. The block is bored to house a sleeve 53 forming a guide for a tool holder 65 urged downwardly by a spring 67 the strength of which may be adjusted by a screw 61. The shank 71 of the tool is secured by a nut 73, and the tool is formed with alternative burnishing grooves 77, 79, one of which may have a sharp angle and one be rounded. To turn the tool through 180 degrees, when it is required to use the other groove, the holder 55 is formed with teeth engaged by a segment 85 pivoted at 89 and integral with opposed handles 87. A spring poppet 95 co-operates with diametrically opposite grooves to hold the tool in position. The parts 19, 27 and 20, 29 are of the same diameter, respectively, so that if the burnisher 21 is not required, the burnisher 31 may be mounted in its place, and the upper mechanism removed. Lubrication means for the machine comprise an oiler 101 connected by passages to an axial channel 105 in the shaft 27 feeding shallow recesses on the surface of the shaft, the oil reaching the bearings of the connecting rod 43. The shaft 19 is similarly lubricated, a chain on the concentric part of the shaft 9 feeding a helical groove in the aslant portion, this lubricating the yoke and adjacent parts.

Filed: 1971-04-26
Abstract: 1340087 Mincing-machines W JENSEN 26 April 1971 [27 April 1970] 11308/71 Heading A4C A machine for mincing frozen blocks of meat comprises a feeding trough 2, a rotating worm conveyor located beneath the trough and formed into two parts having different diameters which convey the meat to a cutting tool, not shown. Pieces of meat placed in the trough 2, are gripped by the larger diameter part 3 of the conveyor, passed along to the smaller part 4 of the conveyor, and then to a cutting housing 5. The smaller part 4 is surrounded by a lining 6 except in its upper region in the area of transition with the part 3, to allow excess meat from the larger part 3, which would otherwise freeze in and block the small conveyor, to escape into the space so provided. A cutting edge 10 on the larger diameter part of the conveyer co-operates with a stationary cutting edge (8) on the lining 6 to cut the meat passing from the larger part 3 so that it may be gripped by the smaller part 4, and helical strips 7 on the inside of the lining 6 co-operate with the worm to continually turn chunks of meat to prevent them freezing and blocking the feed. The pitch of the smaller part 4 increases in the direction of conveyance, the inner surface of the lining 6 is outwardly flared in the conveying direction, and the width of the strips 7 decreses in this direction to allow more space for increasing play of chunks of meat and consequently reduces the chance of blockage. The lining is provided with flanges through which pins 9 pass and attach it to the housing 1. The flanges are provided with eight holes so that portion of the lining and thus the size of the space for excess meat may be altered. In a further embodiment, not shown, the worm conveyer portions of reduced diameter has a constant diameter and is surrounded by a tubular casing having a screw threaded internal surface, the tips of the screw thread having constant diameter while the bases of the screw thread have increasing diameter in the conveying direction.
