Title: A multiple-spindle drilling machine
IPC: B23B39/16
Filed: 1960-10-07
Abstract: 921,941. Tapping; drilling. KARL HULLER G.m.b.H. Oct, 7, 1960 [Aug. 25, 1960], No. 34427/60. Class 83 (3). [Also in Group XXIV] A drilling machine comprises change-speed gearing 16 for the rotation of a number of drilling or tapping spindles, the drive to the spindles being through a pair of spindles 20, 21 and a distributer head containing tiers of gearwheels for controlling the speed and direction of rotation of the spindles. The change-speed gearing rotates a gear 30 on a sleeve splined to the spindle 20. The gear 30 rotates a gear 31 which, through an electrically-controlled clutch 33 and gears 35, 36, rotates a sleeve splined to the spindle 21. The gear 31 also meshes with a gear 41 which can be connected by another clutch 43 to rotate the spindle 21 through gears 44, 36. The splined shafts 20, 21 extend into the sliding distributer head 25 and are connected to shafts 55, 58, Fig. 4. These shafts carry gears 56, 57, 68, 59, 60 to rotate gearing 64, 62, 71 which can selectively drive shafts 67 by operation of selector gears 65 moved by plungers 66, the gearing 64, 62 giving different speeds and the gearing 71 being used to give a reversed rotation for tapping. A tapping spindle 76, Fig. 3, for example, is rotated from a shaft 67, the spindle engaging a nut 77 on an adjustable rod 78. In operation for tapping, the head 25 is fed downwardly at drilling feed speed. Initially, the rod 78 engages the work and is moved upwardly. When a further rod 93 engages the work, a switch 98 is actuated to engage the clutch 33. The spindle 21 and the upper tier of gears then rotate and the shafts 26, 76 rotate causing feeding of the tap. As the shaft 76 rotates so does a shaft 87 which moves a nut 83 carrying a rod 89 and, after a given feed, a switch 90 is operated to disengage the clutch 33 and engage the clutch 43. The tap is withdrawn and the rod 89 subsequently actuates a switch 91 to engage a braking clutch 37. The shaft 87 may be replaced by a drilling spindle when tapping is not required.

Title: Chlorinated rubber products
IPC: C08C19/14
Filed: 1936-12-15
Abstract: Rubber is chlorinated until it contains up to 20 per cent of chlorine, and this product is vulcanized.  The lightly chlorinated rubber may be mixed with fully chlorinated rubber as described in Specification 487,167, and this product vulcanized.  Hot or cold vulcanization may be employed.  Preferably the amount of fully chlorinated rubber does not exceed 70 per cent of the mix.  The products swell less in solvents, oils &c. than do vulcanizates of ordinary rubber, the amount of swelling decreasing with increasing chlorine content, as does also the elasticity.  Increased chlorine also decreases the time required for vulcanizing.
