Abstract: 375,657. Electric incandescent lamps. BRUNETTO, P. BORRI-, 32, Via Piossasco, Turin, Italy. Oct. 19, 1931, No. 29050. [Class 39 (ii).] An electric incandescent lamp is provided with a normal filament 13 and a reserve filament 14 which is automatically introduced upon the burning out of the normal filament, one end of each filament being connected to a leading-in wire 7, and a switch member connected normally between the leading-in wire 6 and the other end of the filament 13 being held apart from a connection to the reserve filament until the normal filament burns out. As shown, the leading-in wire 6 terminates in a loop 10 within which is hooked one end of a wire 11 connected to an end of the filament 13 and passing through a loop 9 at the lower end of a wire 8. The wire 8 is connected to one end of the filament 14 and passes through the stem 3 and cap 2 of the lamp. As soon as the filament 13 burns out the wire 11 is released and tilts about the loop 10 into contact with the loop 9 at the bottom of the wire 8, thereby connecting the filament 14 to the leading-in wire 6. An alarm signal is actuated simultaneously with the introduction of the reserve filament, the signal employed in the example being a pilot lamp 15 shunted across the upper end of the wire 8 and the leading-in wire 7.

Title: Thermo-magnetic overload circuit-breaker
IPC: H01H73/44
Filed: 1950-11-28
Abstract: 689,513. Automatic circuit-breakers. HEIDENWOLF, H., and NAIMER, H. Nov. 28, 1950 [Nov. 28, 1949], No. 29142/50. Class 38 (v) Excessive current in a coil 19 heats and so varies the permeability of a magnetic member 11 that a permanent magnet 16, the poles 17 of which have been engaging the member 11, is released and under the bias of a spring 14 moves into the position shown. A circuit between contacts 5, 6 and which includes the coil 19 and two spring contacts 8 normally bridged by the magnet is thereby broken. An exceptionally high current either D.C. or A.C. through the coil 19 will also release the magnet instantaneously by acting in opposition to the magnet and release may also be assisted by making the contact arms 8 of bimetal so that when heated they press upwards against the magnet with increasing strength. The device is reset by pressing down a button 26 which carries with it two arms 28 bearing on a collar 15 on the rod 13 carrying the magnet. This brings the magnet sufficiently near to the member 11 for the movement to be completed by magnetic attraction, unless the overload persists. The button 26 cannot by itself push the magnet into engagement since after a certain movement the arms 28 encounter a bar 31 and are forced apart. In a modification, Fig. 5, the permanent magnet 40 is fixed but two movable magnetic arms 41, 42, engage the ends of the heated member 43 and the contacts 44. Specification 229,564,[Class 38(v)], is referred to.

Title: Process and apparatus for realizing eyelets at the ends of helical draw springs
IPC: B21F35/02
Filed: 1962-08-02
Abstract: 976,655. Deforming ends of springs. A. E. F. VANHULEN. Aug. 2, 1962 [Aug. 11, 1961], No. 29739/62. Heading B3E. 580 A method of forming an eyelet on the end of a helical spring includes the steps of bringing the spring into a vertical or nearly vertical position, positioning the spring accurately, holding it in this position with at least the lower turn free, moving a stop adjacent the turn to be bent to form the eyelet and bending the turn. Springs from a drum 69, Fig. 13, are fed through a guide 81 to a vertical tube 4 through a gauging device 70 having jaws with co-operating semicylindrical recesses which allow a normal size spring to fall through, a spring of a larger diameter being held and transferred to a discharge shoot 79 as the device 70 is regularly swung by cam means to a position above the shoot 79 there to release the oversize spring. In its passage down the tube 4 the spring engages feelers 57, 63, 64 extending through a longitudinal slot in the tube which serve to allow only one spring at a time to move down the tube 4. The spring 1 falls through the tube 4 to rest on a support 5, Fig. 15, having a helically shaped upper face 6, whereupon a sleeve 20, continuously rotated by a gear 22, is moved down by a fork 24 so that an internal conical wall 27 at its lower end engages rollers 17-19. The rollers 17-19 are mounted on rods 11-13 guided in inclined external grooves 8-10, Fig. 25, in a sleeve 7 forming an extension of the tube 4. The rollers 17-19 are thus moved inwards to contact the spring 1 and are rotated so as to drive the spring 1 in a helical movement to position it against the helical face 6. The spring 1 is then gripped between a stationary jaw 33 and a jaw 34 moved in by a pusher 38, the sleeve 20 is raised to release the rollers 17-19 and the support 5 is moved aside by movement of a carrier rod 29. A member comprising a lamination 39 and stop 40 is then moved forward so that the lamination enters between last two turns of the spring, Fig. 9. A forming tool 44, 45 is then moved in to engage the last turn of the spring and bend it up against the stop 40 to form an end loop 2, Fig. 10. The members 38, 39, 40 and tool 44 then retract to allow the spring 1 to fall into a tubular element 47, Figs. 13, 24. The element 47 is integral with a hub 48 secured to a gear 50 running on a rack 51 so that as the gear 50 is rotated the element 47 carries the spring 1 down to deposit it, with the formed loop 2 uppermost, in a tubular inlet 54 of means for forming a loop at the other end of the spring. A screen 55 serves to maintain the spring in the element 47, and to stop the machine if two springs fall into the element 47. In a modification, Fig. 30, the spring is positioned by a leg 84 on a rotatable member 82.

Title: Improvements in towing blocks for fishing vessels
IPC: B63B21/56
Filed: 1920-10-22
Abstract: 171,880. Bask, C. G. Oct. 22, 1920. Fair-leads.-Towing- blocks forming fairleads for the warps on steam trawlers are fitted with means for preventing violent impact between the blocks and the side of the vessel when the snatch-mechanism is operated to release the warps. Under normal circumstances, the release of the pivoted arm 6 from the suspension 10, to free the warp ropes 20, allows the pulleys 1 to rotate about the pivot 3 with an impulse, furr.ished by the pressure of the ropes, sufficient to make the block strike heavily against the side of the vessel. In the present construction, an arm 8 rotates with the pulley shaft 2 so as to engage the ropes 20 and break the fall, before the ropes leave the block. The warps are guided by two pulleys mounted close together as shown. The pulley for the " forward " warp has an extended bearing 1<x> on the shaft, which forms part of the bearing for the other pulley. The outer and inner surfaces of the pulleys may be coned as shown, also oil-holes 16 may be provided. The bearing-surface between the arm 6 and suspension member 10 is tapered inwardly as shown at 14.
