Title: Improvements in chucking and feed devices for lathes and allied machines
IPC: B23B31/177
Filed: 1938-07-26
Abstract: 511,097. Turning; chucks. FORKARDT, R. July 26, 1938, No. 22246. Convention date, July 26, 1937. [Class 83 (iii)] Bar-feed spindles.-In a lathe or like machine having a bar-feed through a hollow spindle, feed members and clamping jaws are mounted in the chuck adjacent the working point and are both operated by fluid-pressure pistons within a cylinder located at the rear end of the spindle. The machine spindle 1 carries a chuck 2 having jaws 12 operated by bevelled surfaces or an axially sliding ring 10 which is attached to a sleeve 13 within the spindle and carrying a piston 8. Radially movable yielding plungers are located in the chuck between the jaws 12 and are coupled thereto by levers &c. so as to engage feed fingers 19 and press them against the work when the chuck is opened. The fingers 19 are removably attached to a sleeve 20 within the sleeve 13 which carries a piston 9. The pistons 8, 9 are slidable within a double cylinder 3 attached at 4 to the spindle 1 and supplied with fluid by either of the pipes 6, 6a leading to a distributor 5 and a four way cock 7. In operation, when fluid is admitted to the pipe 6 it flows by passages 21 first, to the space C to open the chuck and apply the fingers 19 to the work, and then by restricted passages 22 to the space A to feed the work forwards until the piston 9 engages the end of its cylinder or the work engages a stop. Actuation of the cock 7 then connects the pipe 6 to exhaust and the pipe 6a to supply, whereby fluid first flows by passage 23 to space D to close the chuck and release the fingers 19 and then by restricted passages 24 to space B to withdraw the fingers axially. The restricted passages 22, 24 ensure the sequential operation of the gripping and feeding means. If the stroke of the piston 9 is insufficient to feed the work the requisite amount, more than one stroke may be made and the plungers which actuate the fingers 19 radially may be operated directly from the sliding ring 10 instead of through levers. The stationary distributor 5 may be located at the left of the cylinder 3.

Title: Improvements relating to copying or profiling machine tools
IPC: B23Q1/72
Filed: 1951-09-25
Abstract: 683,055. Engraving. DECKEL, H., and DECKEL, F. W. Sept. 25, 1951 [Oct. 26, 1950], No. 22422/51. Class 100 (ii). [Also in Group XXII] The work table 10 and pattern table 12 of a copying or profiling machine tool, such as a copy - milling machine having a fixed cutter and tracer, are interconnected by a member 34 which is secured to the pattern table and engaged by opposed pairs of ball-bearings 18, 26 and 30, 32, plain rollers, or balls so that the two tables are rigidly interconnected for copying movement in the horizontal directions a but are freely adjustable for relative height by individual adjustment of their supports. The rollers 30, 32 fitted in a block 28 secured to the work table 10 engage the sides of a recess 42 in the member 34 to provide the coupling in one direction and the rollers 18 fitted in recesses 16 and opposed by rollers 26 on blocks 22 each engage a flange 40 to provide the coupling in the other direction. This interconnection eliminates the clearance that would be necessary with a plain sliding coupling but, if the two pairs of rollers 18, 26 are co-axial, the work table can still distort slightly under the weight of a work-piece, without jamming the coupling. To obviate the accurate fitting necessary for the coupling described above, the rollers 18 may be mounted on a plunger loaded by an adjustable spring and the block 28 may have an off-centre slit fitted, if necessary, with an auxiliary spring so that one roller 30 or 32 is elastically loaded. More than two tables may be interconnected and additional means may be provided for securing the pattern table against vertical movement.

Filed: 1935-08-09
Abstract: 461,077. Ignition timing. TRIGGS, W. W. (Moore Inventions Corporation) Aug. 9, 1935. No. 22493. [Class 7 (iv)] The ignition timing is varied according to changes in induction pipe suction or exhaust pressure through a cam shaped to effect retardation while the engine is idling, to afford a maximum advance under light loads, and an advance from a retarded position with increasing speed under full load operation. A plunger 24 works in a cylinder 18 in communication with the induction pipe. Two springs 28, 30, one coming into action after the other, oppose the suction, interlacing of the springs being prevented by an intervening sleeve 32. The piston rod forms a rack engaging a toothed quadrant 44 fixed to the same spindle as a disc having a cam-groove 60. Alternatively, the groove may be formed in the quadrant itself. The groove is engaged by a roller carried by a pivoted lever 62 connected to the ignition circuit interrupter mechanism. In a modification, the end of the rack within the closed end of the casing 50 is also formed with a piston, suction created within the airtight space between this second piston and the closed-end serving to supplement the action of a single spring around the rack in opposing that of the induction pipe suction on the main piston.
