Title: Improvements in or relating to feed mechanism for machine tools
IPC: B24B47/04
Filed: 1931-02-06
Abstract: 363,544. Driving milling &c. machines. AKTIEBOLAGET SVENSKA KULLAGERFABRIKEN, 17, Artillerigatan, Gothenburg, Sweden. Feb. 6, 1931, No. 3890. Convention date, Feb. 8, 1930. [Class 83 (iii).] The rate of automatic teed in a machine tool such as a grinding, drilling, or milling machine or a lathe diminishes automatically as the load or cut done by the machine increases and vice versa. In Fig. 1 the spindle 7 of the grinding wheel belt-drives the rotor 11 of an A.C. motor the " stator of which is also mounted to revolve and drive the pulley 16 which drives the feed screw 26 by belt 17 and worm and gearing 22, 23. The speed of the stator 14 and therefore the feed 1 depends on the relative speed of the rotor 11 which is affected by the speed of the grinding wheel. If the grinding wheel is sufficiently overloaded, the feed screw 26 will ultimately be reversed to withdraw the tool from the work. In a modification the feed is driven by a standard type A.C. motor, the current to which is supplied from a standard A.C. generator the armature of which is coupled by a belt drive to the grinding wheel spindle. In direct current supply the current taken by the tool driving motor is led to the field of the feed motor to slow it down or vice versa or the armature current of an A.C. driving motor can be rectified and applied to the field of a D.C. feed motor. A mechanical differential is shown in Fig. 4 in which a disc 41 carrying planet pinions drives the feed screw 26. The rate of driving of the feed depends on the variable speed of the sun pinion 43 driven by belt from the grinding wheel spindle relative to the constant speed of the internally toothed ring gear 44 driven by belt 46 from a motor 45.

Abstract: 163,423. Dubois, A. J. Feb. 10, 1920. Vehicles, marshalling and manipulating. - Multiple-tier mine cages are loaded and unloaded by means of two auxiliary cages which are set horizontally when being charged with the full trucks, and which are then swung into a vertical position to allow the full trucks to be pushed into the main cage. Each auxiliary cage comprises a frame 1 having rollers 12 running on tracks 13 and centrally connected by bars 14 and chains 37 to hydraulic or other hoisting- mechanism. The trucks 36 are run on to platforms 2 carrying rollers running on the circular trackways 34 in the auxiliary cage, the end platforms also carrying ground contacting rollers 6, and all the platforms being geared together by curved racks 10 and engaging pinions 11. The two auxiliary cages are arranged one on each side of the main shaft, and one cage is loaded with full trucks. By means of the hoisting-mechanism, the auxiliary cage is then raised to the vertical position shown in Fig. 2, one end of the cage being kept on the ground level by means of a movable guide. The rollers 6 of the end truck platform cause the platform and truck to rotate relatively to the auxiliary cage, and the gearing 10, 11 similarly rotates the other trucks. By means of the usual pushers, the full trucks are then pushed into the principal cage and so push the empty trucks out of that cage into the second auxiliary cage. The auxiliary cages are then lowered and the operation repeated, the tilting this time being in the opposite direction to bring the auxiliary cages oppnsite the second main cage. When adapted for main cages having an odd number of tiers the raising bars are connected to a transverse shaft mounted in slotways in the auxiliary cages.
