Abstract: 132,116. Marks, E. C. R., (Pollock, R. T.). Nov. 4, 1918. Disk apparatus; driving and feed devices; rests; work-holders.-In a metalworking machine more particularly for milling, turning, or grinding crank-shaft pins or journals, the stationary shaft is operated on simultaneously by several cutters, such as milling-cutters 83, projecting inwards from rotating rings 60, Fig. 8, suitably held in frames 54, Figs. 1, 2, and 8, mounted on interchangeable blocks 55 of required height to position the centre of each ring 60 with reference to the part to be machined. The crank-shaft is first mounted in chucks 27, 43 on the elongated tail-stock spindle 25 and the headstock 38 respectively. This is done while the headstock 38 is in its extreme position to the right, Fig. 1. By sliding the headstock 38 to the left by means of a hand-wheel 31 and rack 53 the crank-shaft is carried longitudinally into position in the ring 60. It is then indexed by a worm and worm-wheel controlled by stops on the headstock 38 so that the journals are positioned correctly with regard to the various cutters, and clamped in position by steady-rests or workholders comprising jaws 110, Fig. 4, held by springs 113 and screws 112 in a slightly adjustable manner on legs 111 pivoted to a base 115 and held together by a bolt 117, the elongated nut 119 of which has a hand-wheel 120 and a hook 123. The machining may be done by cutters 83 secured on the end of the spindle 67 by a screw collar 80 and driven by a pin 81. The spindle 81 runs in ball thrust-bearings 75, 103 and in a sleeve 68, which is longitudinally adjusted in a projection 64 on the ring 60, to regulate the depth of cut. A bevel pinion 100 meshing with a worm-driven toothed ring 101 drives the spindle 67, and teeth 182, Fig. 8, on the ring 60 engage a second worm to revolve the ring 60. Both sets of worm shafts are driven through chain-gearing from a main pulley 30, through clutches operated by levers 130, 1300. The crank-shaft is withdrawn by indexing and withdrawing the headlock 38 in the reverse manner to that for inserting it. The frames 54 are preferably steadied by a girder 133.

Title: Improvements in or relating to a device for controlling the position of a bicycle dynamo
IPC: B62J6/06
Filed: 1956-05-02
Abstract: 810,739. Mounting dynamos on cycles. LUCIFER S.A. May 2, 1956 [May 10, 1955], No. 13612/56. Class 35. A device for controlling the position of a bicycle dynamo comprises a shaft 4 rigidly fastened to the casing of the dynamo and rotatably mounted in bearings 5 provided in ears 6 of a support 7, a lever 14 movable between positions in which it retains the dynamo in an operative and inoperative position respectively and a spring 9 for urging the lever to the operative position, the lever 14 being provided with two stops 18, 19 which serve to limit the angle of oscillation of the dynamo under the action of the spring. The lever 14 pivots about lugs 23 mounted in notches in the ears 6 of the support 7. A detachable pin 11 is housed in the shaft 4. When the dynamo is in its inoperative position (Fig. 5) one end 20 of the pin 11 rests against the abutment stop 19. The lever 14 is maintained in this position by the end 12 of the spring 9 acting on an abutment 13 (Fig. 8) of the lever. A weak return torque tends to oscillate the lever 14 about the lugs 23 in the direction of the arrow f (Fig. 7). By exerting a thrust B (Fig. 5) on the lever 14 the abutment stop 19 will be released from the end 20 of the pin 11 and the dynamo will be displaced angularly in the direction of the arrow h by the spring 9 acting on the end 21 of the pin until the dynamo driving roller abuts the cycle tyre. When the user brings the dynamo back by hand to the inoperative position the stop 19 comes against the end 20 of the detachable pin 11 so that the dynamo is maintained in its inoperative position (Fig. 5). The spring 9 has spaced-apart turns (Fig. 4) so that it exerts an axial thrust A on the support 7. To dismount the device a lid 26 is removed from the support 7, a thrust B is exerted on the lever 14 until the end 20 abuts the stop 18 and then the support 7 is moved along the shaft 4 against the axial thrust A to free the stops 18, 20. The dynamo is then turned through 180 degrees from the inoperative position to release the spring 9.

[Class 28 (ii)] [See also Group I] A masher for vegetables or meat comprises a vessel 1, having a non-corrugated perforated bottom 6, a rotary helical presser 11 so arranged that its lower edge sweeps over the perforated surface, and scrapers 15 rigidly mounted on the vessel to co-operate with the peripheral edge of the presser. The bottom 6 is formed with a bearing 7 for the shaft 8 carrying the presser 11, a nut 10, with an interposed spring if desired, retaining the parts in position. The shaft is cranked at its upper end to form an operating handle. The space between the edge of the presser 11 and the wall of the vessel 1 increases from the lower end of the edge to the upper end. The scraping blades or knives 15 are of angular section and are fixed, e.g. by soldering, on the wall of the container, in inclined positions. The lower ends of the scrapers are spaced from the bottom 6 to permit the passage of the lower part of the presser 11. The scrapers, in association with the presser, serve to disintegrate the material and to return it towards the bottom 6 when it tends to escape upwardly. The scrapers may have indented edges to assist disintegration. The vessel 1 and its bottom may be of any desired shape, but as shown, the vessel is conical, a handle 3, being soldered into a recess 2 and provided with hook ends to support the vessel on the utensil intended to receive the mashed product.
