Title: Permanent mold for casting multi-cylinder engine blocks
IPC: B22C9/06
Filed: 1938-12-19
Abstract: 522,842. Making engine cylinders: foundry moulds and cores. WAGNER, M. Dec. 19, 1938, No. 36943. [Classes 83 (i) and 83 (ii)] Extracting castings.-A permanent mould, Figs. 2, 4 and 5, for casting cylinder blocks of internal combustion engines comprises mould parts 14 ... 18, cores 23, 18, 207, 208, 176, and a gate member 192, all hollow and cooled by circulation of oil, and also solid cores 69, 70, 71. The part 14 is stationary and the other parts are moved to open the mould, as shown in Fig. 2, and to close it, as shown in Figs. 4, 5 by double-acting fluid-pressure cylinders controlled by valves 270, Fig. 16, 17, operated to open conduits 277 ... 281, 285 ... 289 in desired sequence to pressure supplied at 275, 283 or to exhaust at 276, 284. The valve pistons 290, 294 are moved through rack and worm gearing 295, 300 by a reversible electric motor 301 started in the desired direction by closing switch 302 or 303 by a hand operated relay which keeps the switch closed until opened by opening the main switch or directly by a stop 309 on the rack 295 engaging the switch arm 306 or 311 at the end of the mould closing or opening stroke. To open the mould the switch 303 is closed and the movement of the pistons 290, 294 to the right first connects conduit 277 to pressure instead of to exhaust and conduit 285 to exhaust instead of pressure causing the core parts 71 and 176, Fig. 5, to move out horizontally, and cores 20, 21, Fig. 4, out horizontally and the crank-case core parts 24, 27 down. The reversal of supply to the second pair of conduits 278, 286 causes piston rods 167, Fig. 2, to rise thus lifting the crosshead 19, carrying the gate member 192, cylinder cores 207, and valve aperture cores 208, and then by stops 172 lifting the crosshead 171 with the mould part 18 and the extracted core part 176. At the same time other piston rods move the crank-case core parts 23, 25, 26, 28, Fig. 4, and the tappet recess cores 69, 70, Fig. 5, laterally to free them from projections of the casting. The reversal of supply to conduits 279, 287 causes the table 232, with the core parts 23, 25 26 and 28, to move down. The reversal of supply to conduits 280, 288 causes the mould parts 15, 16 to move out to the front and rear of the machine and part 17, Fig. 2, which forms part of the end wall of the mould to move out at an angle. The reversal of supply to conduits 281, 289 causes a table 40, carrying the mould part 15, tomove down and leave the casting 31 exposed for removal. At this moment the switch 303 is opened by the stop 309. The closing of the mould is effected by closing the switch 302, all the movements being an exact reversal of those occurring during opening except that, after the mould parts 15, 16, 17 have been moved in, the action is stopped by opening a main switch to allow the water jacket core 117, Fig. 5, to be placed in position. The action is re-started by closing the main switch and switch 303.

Filed: 1975-09-09
Abstract: 1492080 Supporting dental handpieces SIEMENS AG 9 Sept 1975 [13 Sept 1974] 37161/75 Heading A5R [Also in Division F2] A retractable linkage 2 for a supply line 3 of a dental handpiece 4 comprises a pair of links 8, 9 pivotally interconnected at 12, with the link 9 being pivoted at 10 on an elongate support member 11 carried on a dental fixture 1, the supply line 3 running from the handpiece 4 over a roller 6 which is freely rotatably journalled on an axis 7 on the free end of the arm 8. A torsion spring 13 at the pivot 12 biases the arm 8 to rotate anticlockwise towards the fully retracted position shown in full. A tension spring 14 is connected between the support 11 and the arm 9 and has an over-centre action which urges the arm 9 to rotate clockwise or anticlockwise when the arm 9 is inclined to the right or left respectively of the central i.e. vertical position of the arms 8, 9, shown chain-dotted. Thus both springs 13, 14 jointly serve to fully retract the mechanism once the arms 8, 9, pass the central position as the unit retracts towards the right; whilst, in use, i.e. with the linkage fully extended to the left for operation of the dental handpiece 4, the over-centre spring 14 now opposes and largely neutralises the bias of the torsion spring 13 such that there is little or no spring load acting on the supply line 3 of the dental handpiece 4. Additionally the spring 14. at all times, exerts a downward bias on the roller 6 to maintain it in contact with the support member 11. The supply line 3 leads back from the roller 6 through an aperture 16 in the member 11 to a supply arrangement 17 which makes available air, water and/or electric current for supplying the handpiece 4. and rests on the flat surface 18 of the support 11 or directly on the fixture 1, the handpiece 4, when not in use, resting on a cradle 5. Additional arms with associated spring means (not shown) could be used to increase the maximum extension length of the supply line.
