IPC: B23Q37/00
Filed: 1921-10-04
Abstract: 181,311. Dalton, H. June 10, 1921, [Coravention date]. Combined turning, drilling, and milling machines.-A combination lathe, drilling, and milling machine comprises a vertical drilling or milling spindle, mounted above a reciprocatory work table, an horizontal milling spindle, and a lathe of which the bed has a detachable section to accommodate a face-plate on the spindle, all the various units being operated from the lathe spindle which serves as a driving shaft. As shown in Figs. 1 and 1<a> the lathe spindle 9, driven from a stepped pulley having back gears 13, carries a wheel 20 driving through a reversing pair of meshing gears 22 operated from a lever 24 a. shaft 21 connected by change gearing to the lead screw 18. In a neutral position of the lever 24 the lead-screw driving-gear is inoperative. The headstock spindle also carries a gear 29 which drives through bevel and spur gearing and handoperated clutch 38 the vertical milling or drilling spindle 44 journaled in a bracket 10 secured to the headstock. The vertical spindle may be fed from the hand-wheel 55 or from a ratchet lever 51, a clutch 48 being provided so that either feed mechanism may be used. For milling, the spindle is positioned by means of the hand-wheel gearing and locked by a screw 56. The spindle is counterbalanced by a weight 58 guided in the frame 10. For horizontal milling, one end of a cutter arbor 59 is clamped in an extension of the spindle 9 which is hollow and has its opposite end tapered. The cutter arbor is supported in a member 60 on the overhanging arm 61, the latter sliding into a tubular portion of the headstock when the vertical spindle is in use. The work table 64 is mounted on a compound slide on a knee 11 and is operated from the main spindle 9 through gears 30, bevel gearing 68, changespeed-gear box 71, telescopic shaft 74, spur gearing 75, and spindle 77. The latter spindle carries a worm engaging the table feed-screw 78 and the front side of the work table is provided with adjustable dogs 80 which engage a trip lever 81 to disengage the feed worm at opposite ends of the traverse. Cross-feed of the work table is effected from a crank-handle 86, and the knee is vertically adjusted from a second crank-handle 82, index dials 87 and 88 being provided for the respective adjustments of the knee and cross slide. In Fig. 1 the machine is shown with the detachable section of the lathe bed removed to accommodate a. face-plate.

Abstract: 364,125. Magazine gramophones combined with wireless receivers. SMITH, G., 34, Clieveden Road, Thorpe Bay, Essex. Sept. 30, 1930, No. 26476/31. Divided on 357,554. [Class 40 (ii).] Comprises a modification of the invention described in Specification 357,554, whereby one of a series of wireless broadcast programmes may be selected for reproduction instead of or in addition to the selective reproduction from any one of a series of gramophone records. To adapt the apparatus for reception of a selected wireless broadcast programme a number of rods 101, Fig. 19, are provided. Each of these rods is independently supported by one of a number of springs 103, Fig. 7, in a position to be engaged by sets of projections 104 mounted on the record carrier c in different planes at rightangles to the axis of the carrier. Each rod 101 is connected to the grid of a thermionic valve and carries a cone 100x which either makes contact with a spring arm 102 connected to the electric pick-up or with a spring arm 105 connected with a circuit tuned to receive a particular wireless broadcast programme. The carrier c is provided with different sets of projections 104 so that it may be turned into position for selection of a desired broadcast. One of the projections 104 of each set is adapted to deflect one of the springs 103 to cause the cone 100x on the rod it supports to engage one of the spring arms 105 to connect up a wireless receiving circuit, while the other projections 104 of the same set deflect their springs 103 only sufficiently to disconnect each cone 100.r from each spring arm 102, thus disconnecting the pick-up circuit. When the apparatus is arranged for reception of broadcast programmes only, spring arms 102 are dispensed with.
