Title: Improvements in or relating to multiple tool heads for grinding, drilling or like machines
IPC: B23B39/20
Filed: 1938-03-03
Abstract: 512,438. Grinding. GAITZSCH, F. March 3, 1938, No. 6712. Convention date, March 3, 1937. [Class 60] [Also in Group XXII] In a multiple tool head for a grinding &c. machine having a number of tool spindles radially arranged in a turret which surrounds a driving shaft mounted in the fixed base of the head and driven by means external to the head, the driving shaft is rotated by toothed gearing and is provided at one end with coupling means for connecting it to the tool spindle which is placed in axial alignment therewith. The radial tool spindles 14 are rotatable in a turret 17 which is rotatably mounted on a base 2 by means of a flange 21 screwing on the base and a collar 20 secured to the turret by screws 18. A central stationary bracket 1 attached to the base carries a driving spindle 12, rotated directly or indirectly from a motor, and connected by bevel, belt or helical gearing 10 and sliding spur gears 7 to a shaft 4 in the bracket. Axial motion may be imparted to the shaft 4, to engage it with each of the spindles 14 in turn, by means of a yoke 23 pivoted to the bracket at 24. A projection 29 on the yoke engages an arcuate member 30 rotatably carrying a socket 37 'to which a hand lever 38 is pivoted at 36. A central rod 39 in the lever 38 may be depressed against a spring so as to extend into the projection 29 whereupon rotation of the lever about the pivot 24 will move the shaft 4 to and from the driving position, a spring detent 25 maintaining it in either position. With the rod 39 released, the lever 38 may be rotated about the pivot 36 into a horizontal position and then engaged with any of the notched projections 46 on the cover 31 of the turret, whereby the operator is enabled to rotate the turret into a new position. The turret is locked by a spring plunger 47 which may be depressed by a rack and pinion 48 operated by a hand lever 49. The cover 31 protects the turret mechanism from dust and the arcuate member 30 forms a dust proof connection between the lever 38 and the cover. In a modification the lever 38 is dispensed with and the turret rotated by handles on the cover 31, the yoke 23 then being operated by levers connecting the member 30 to the handle 29 so that the drive will be disconnected when the index bolt 47 is withdrawn. In another modification the shaft 4 may be arranged below the plane of the spindles 14 and the driving connection made by means of toothed or friction gears on the shaft and spindles. Further tool spindles arranged in different positions or at different angles in the turret 17 may be driven from the radial spindles 14.

Filed: 1957-02-28
Abstract: 808.793. Reservoir pens. BERGONZO, C. Feb. 28, 1957 [June 28, 1956], No. 6762/57. Class 146(3) A multiple ball-point pen having a plurality of ink cartridges 12 which can be projected from a position within the barrel 1 to writing position defined by a locking device, an actuating member 19 extending from the rear end of the barrel which permits a selected cartridge to be brought against the action of a spring, into writing position, and a device for selecting a desired cartridge, is characterized in that the selection device - has an eccentric rod 18 carried by a rotatable sleeve 15, the angular displacements of which are controlled by axial displacement of the actuating member 19. As shown, rods 10 to which ball-point cartridges 12 are detachably secured, are slidably mounted in a plate 8 having guiding apertures 9. The rods 10 are pressed rearwardly by springs 11, but may be projected into writing position by the push rod 18. The sleeve 15 is fixed to the actuating member 19 which is guided axially of the barrel by a rod 17 having a surrounding spring 24 which presses the members 15, 19 rearwardly. The sleeve 15 has two sets of cams 39, 40 which co-operate respectively with actuating pins 42, 41 on the barrel to effect rotation of the sleeve 15 upon depression and release of the member 19, thereby rotating the push rod 18 in stages about the axis of the barrel into a position to project a desired cartridge. This position is indicated by coloured sectors 51 on the sleeve 15 visible through a window 50 in the barrel. When the desired cartridge has been selected, the pin 42 is moved along a slot 43 out of the path of cams 39 thereby preventing further rotation of the sleeve 15 and push rod 18. With the pen held vertically so as to cause a loose ring 34 to drop on to a seating 38, the member 19 is depressed to project the selected pen, and is locked in such position by a spring-pressed pin 26 which engages under the front edge of a sleeve 30 secured to a cap 31. To release the pin 26 for retraction of the pen, the member 19 is further depressed causing the pin to be moved inwardly by engagement with an inclined surface 35 on the ring 34 and to snap into a groove 48 in the ring. Upon release of pressure on the member 19, it moves rearwardly carrying with it the ring 34. The movement of the ring however is stopped by the sleeve 30, so that the pin 26 snaps out of the groove 48 and moves upwardly inside the sleeve 30 as the member 19 continues its rearward movement. The ring 34 can then drop back ready for the further operation of the pen. Ball-bearings 22, 25 are provided between the member 19, and a knob 20 thereon, and between the end of the spring 24 and the plate 8 to avoid reverse rotation of the sleeve 15.
