Filed: 1937-12-24
Abstract: 499,349. Grinding. NORTON CO. Dec. 24, 1937, No. 35766. Convention date, Dec. 24, 1936. [Class 60] [Also in Group XXII] In a work-supporting and rotating mechanism for a grinding machine, particularly a crankshaft grinding machine, the work is gripped between a clamping jaw and an opposed supporting member rotatable with the machine spindle, the clamping jaw being actuated by an electrical device under control of a manually operable reversing switch for the spindlerotating motor so that the clamping jaw cannot be disengaged until the spindle is at rest. The machine comprises a bed 22 having horizontal guides 21 for a work-table 20 carrying worksupporting heads 27, 28 and movable longitudinally relatively to a laterally fed grinding- wheel slide. The work spindles 29, 30 are driven by gears 35, 36 and chains 39, 40 from a shaft 41 having a gear 51 splined thereon and driven by a chain 50 and belts 46 from an electric motor 45. The chucks 57, 58 are secured to the spindles 29, 30 and the latter are splined to sleeves 155 carrying the driving gears to preserve the drive when the heads 27, 28 are adjusted axially to accommodate work of different lengths. The gear 36 is angularly adjustable on its sleeve by means of a further sleeve 160, Fig. 3, keyed to the sleeve 155 and carrying two tangentially arranged screws 167 engaging a plug 162 in the gear, clamping being effected by bolts 166 and elongated slots. This adjustment permits the drive to the two chucks to be synchronized so that there is no backlash between them.

Title: Improvements in circular weaving looms
IPC: D03D37/00
Filed: 1938-12-13
Abstract: 580,800. Circular looms; shedding-motions ; stop-motions. EZBELENT, G. E. Dec. 13, 1938, No. 36299. Convention date, Dec. 15, 1937. [Classes 142 (i) and 142 (ii)] The warp threads 3 pass from bobbins or beams through fixed guides 30, 31, heald eyes 32 and blocks 45 to the fell at the centre tube 4. The blocks 45 slide up and down the radially arranged plates 12 which serve as the shuttle race being slotted at 11 to receive rails 10 fixed to the curved base plate 8 of the shuttle. One or more of the shuttles carries an electric motor 13 driving through irreversible gearing 14, 15 wheels 18 gearing with the plates 12 which serve as a rack. The several shuttles are kept apart by the resistance of permanent or electromagnets 21 or a magnet 91, Fig. 7, on one shuttle A may influence a core 92 on the adjacent shuttle B and control the speed of the latter either through variable resistance or by adjusting the brushes of its motor as shown. Current is supplied to the motors 13 and magnets 21 through rails 50, 51, 61 and conducting blocks 52, 53, 62 let into certain of the plates 12. Should a weft thread 5, Fig. 6, break a switch 73, 74, 75 closes a circuit through a solenoid 66 which opens the switch 64, 65 and stops the machine. Should a warp thread 3 break, the lever 87 would be lowered by its spring 89 and close the solenoid circuit through the switch 81, 82, again stopping the loom. The healds 33 are pivoted to levers 34, 35 which can be raised by springs 37 so that their eyes are at level b, Fig. 2, or can be depressed an then locked by catches 39 with their eyes at the level a. The blocks 45 carry rollers 49 to engage the curved sides of the shuttle blocks 8, and these blocks when free, will, due to the tension of the threads 3 take up positions at the levels a, b, i.e., just below and above the the centre plane of the shuttles, and they will be pushed upwards or downwards to effect the shedding by the shuttles themselves. Any block 45 which is thus raised as shown in Fig. 2, will engage the tail 38 of a lever 34 and will lower the heald eye from level b to level a and the block when free will come to level a and will be depressed by the next shuttle; it will then engage the tail 43 of the catch 39 and the spring 37 will raise the heald eye to the level b. The weft thread 5, Fig. 4, is beaten into the fell at the tube 4 by a hammer 22 reciprocated or oscillated by an eccentric 29 on the shaft of the motor 13. A rigid tube 4 may be replaced by an adjustable polygonal one, the sides 113, 114, Fig. 11, of which telescope into each other and are connected to levers 115 so arranged with adjustable rings 119, 120 that the size of the tube can be varied during working. The ring of plates 12, Fig. 9, can be oscillated by a lever 104, cams 102, and motor 98 to produce tubular fabric with zig-zag warps as shown in Fig. 10.
