Patent GB-147459-A (GB)
Abstract: 147,459. Chosson, J. May 8, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Smoke-conduits systems.-A locomotive chimney is arranged to discharge rearwardly into an horizontal tube 2 extending over the boiler, the tube being divided into two portions 4 and 5 to avoid the steam dome, these portions uniting to form a single tube at the rear of the locomotive. The smoke tube thus arranged projects into the funnel-shaped end of another horizontal tube arranged above the tender, the latter tube in turn engaging similarly a tube arranged on the first carriage, the smoke being carried in this way to the rear of the train before being discharged. An induced draught is created by the rush of air into the funnel-shaped tube ends, and when the locomotive is stationary a sliding door 3 situated above the chimney is opened to allow the smoke to escape.

Abstract: 1383073 Tool holders HOUDAILLE INDUSTRIES Inc 29 March 1972 [1 Sept 1971] 14852/72 Heading B3B An adapter assembly for a tool holder comprises a body member 14 adapted to be secured to a tool holder and having a tapered bore 15, a radially compressible collet member 17, 30 received in said tapered bore and having a threaded bore 18, 34 for receiving the threaded end 13 and shank of a tool 11, a nut 19 threaded on to said body member and having means for urging said collet member axially with respect to said bore, and a back-up screw 21, 31 threaded into one of said members for prvoiding a force on the end of a tool shank, the threads of said threaded bore and the threads of the back-up screw being of dissimilar pitch and arranged to increase said force as a consequence of any joint rotation of the tool and the back-up screw with respect to said collet due to tool slippage within said collet, to thereby terminate any such slippage. The back-up screw has an extension 23, 32 but such extension could be separate therefrom. Stops in the assembly ensure that at least half of the threaded portion of the tool engages with the threads in the collet. The collet may be unthreaded and have an internal sleeve therein that is threaded. Fig. 1 shows the back-up screw in threaded engagement with the collet whilst Fig. 3 shows it in engagement with the body 14. In operation the backup screw 21 is retracted to engage limiting means 26. The tool 11 is then turned to mate its threads 13 with threads 18 until end portion 13 engages extension 23 approximately finger tight. Nut 19 is then tightened, but not fully. At this stage the tool can be backed out to provide the correct axial length of the assembly. The nut 19 is given its final tightening, after which the backup screw 21 is given a further tightening until it is tight against the end of the tool. Any tendency of tool 11 to rotate in the collet would result in axial inward movement. The frictional contacts between the tool and the back-up screw will lock the parts together because of pitch dissimilarity. The two screw threads may be of opposite hand.
