Filed: 1955-04-15
Abstract: 786,439. Turbine plant. CHRYSLER CORPORATION. April 15, 1955, No. 10981/55. Class 110 (3). A multi-stage turbine has a pair of axiallyspaced rotors, each rotor being supported on a separate shaft, and the two shafts are coupled together by means of an axially-disposed torsion or quill shaft which is adapted to compensate for misalignment of the two shafts. One end of the torsion shaft is connected to one of the turbine rotor shafts and the other end of the torsion shaft is connected to the other turbine rotor shaft by means of a clutch device which permits relative rotation between the two rotors in one direction only. In Fig. 1 a gas turbine engine is shown mounted on a road vehicle, the engine comprising a centrifugal type air compressor 64 driven by a turbine 66, air from the compressor being pre-heated in a heat exchanger 70 and then entering combustion equipment 72, the hot gases produced driving the turbine 66. The turbine 66- comprises a compressor-driving turbine 156 and a separate power turbine 158 which drives the road-wheels through gearing 68 and shaft 44. The compressor rotor 130 and turbine rotor 156 are mounted at the ends of a shaft 122 which is mounted in bearings 116, 118 within a casing 113. The gases leaving the high-pressure rotor 156 impinge on the blades of the low-pressure rotor 158 which is secured on shafting 180 mounted in bearings 188, 190 within the casing 114. A pinion 204 is mounted on the shafting 180 and transmits drive to the gear train 206, 208. A torsion or quill shaft 234 is connected at one end by a splined coupling 232, 238 to the shaft 122 and at its other end by a splined coupling 230, 240 to the shaft 224 which is mounted in bearings 216 within the portion 182 of the shafting 180. A one-way drive coupling is provided between the shafts 224 and 182 comprising rollers 222 and inclined surfaces on the member 218 which is splined to the shaft 224. This arrangement prevents the power turbine 158 from over-running the compressor turbine 156, the turbine 158 being drivingly connected to the compressor 130 if it tends to overspeed, for example when the vehicle is descending a hill. Sealing devices 148 and 168 are provided on the outer sides of the bearings 116, 118 and a similar sealing device 196 is provided on the downstream side of the power turbine rotor 158. A diaphragm 160 and sealing means 172 are provided between the two turbine rotors. The splines at the end of the torsion shaft 234 are spherically shaped to allow for misalignment of the shafts 122 and 224. The shafts 122, 234, 224, 182 and 184 are all hollow and provide a means whereby the splines and bearings 216 may be lubricated.

Abstract: 636,162. Inking-apparatus. BRECKNELL, MUNRO, & ROGERS, Ltd., and DOLMAN, H. J. April 24, 1948, No. 11312. [Class 100 (ii)] An inking roller of the kind having an absorbent covering adapted to be supplied with ink comprises an internal reservoir and an enclosed duct or ducts extending from near the axis of the roller to the peripheral wall thereof, whereby when the roller is stationary and the level of ink in the reservoir is below that of the interior ends of the ducts no ink will be supplied, but when the roller is rotated the consequent agitation feeds ink through the duct or ducts to the absorbent covering. As shown, the roller comprises chambers 12 and 13 separated by a partition 3 provided with radial holes 14, 15, 16 and 17 and an axial hole 18. The radial holes carry wicks which supply ink from the chambers 12 and 13 to a felt covering 11 on the exterior of the roller. When the roller is stationary the level of ink is just below the level of a wick placed in the hole 18, but when the roller is rotated the ink is agitated, thus causing the ink to be fed to the felt covering by the wicks in the holes 14 ... 18. The supply of ink in the roller may be replaced through a filling duct 32 in a spring-urged sleeve 311 which may be projected outwardly from a cylindrical wall 26. The wall 26 has as annular extension 24 screwed to the member and provides a bearing surface 6 concentric with a bearing surface at the opposite end of the roller. In a modification the roller may be supported by a single bearing at one end by means of a longitudinally extending ink duct which carries a sleeve rotatably mounted in a bearing supporting the roller.
