Patent GB-122558-A (GB)
Title: Improvements in and relating to Bases for Incandescent Electric Lamps.
IPC: H01J9/28
Filed: 1918-04-09
Abstract: 122,558. Ghijsen, H. C., and Naamlooze Vennootschap Vitrite Works. April 9, 1918. Electric lamps. - In making lamp-caps, each pair of contact plates in the form of a single blank, Fig. 10, is fed into a plunger head, the connecting strip is cut, and the tongues thus formed are bent up as the plates are placed on the pins of a mould. The insertion of the shell of the cap in the mould before filling the shell with insulating- material forms a separate operation. In one form of apparatus, the plunger 11, Fig. 4, works in a cylinder over moulds on a rotary table. A contact blank is pushed along a groove in an arm carrying the cylinder, passes through a lateral opening into a vertical passage 14 in the plunger 11, and falls on to a bridge 30 at the lower end of the passage, the section of which is similar in form to the blank. Within the plunger slides a core 20, having a flange 22 which is normally pressed by a spring 21 against a closing ring 23 in the plunger. The lower part of the core consists of a fork 25 the prongs of which, being similar in cross-section to the contacts, slide in the passage 14 in the plunger. A chisel 29, shaped so as to be guided by the prongs of the fork 25, is attached to a stem 26 loose within the core but provided with adjusting nuts 28. Within the upper part of the core is a spring-pressed cylindrical hammer 32. A slot in the hammer contains two inclined spring-pressed arms 36 having abutments 39 to restrict their outward motion. When the core 20 is lowered by the driving mechanism, all the parts descend simultaneously until the plunger is arrested by the mould. The core and fork continue to move, but the hammer 32 is shortly afterwards arrested by the engagement of the arms 36 with the ring 23 of the plunger 11, so that the hammer spring 33 is compressed. By the time that the fork 25 and chisel 29 meet the blank resting on the bridge 30, a sleeve 42 screwed on to the core has slid over the arms 36 of the hammer sufficiently to enable them to pass through the ring 23, so that the released hammer strikes the chisel and causes severance of the contacts at the bridge 30. Further descent of the fork bends up the tongues against the sides of the bridge 30 and pushes the contacts on to the pins of the mould, which enter holes 45 in the fork. The lower edges of the bridge 30 are bevelled to prevent the tongues being held as the plunger reascends. Specification 12739/02, [Class 39, Electric lamps &c.], 8988/10, [Class 83 (iv), Metals, Working], and 111,139 are referred to.

Filed: 1942-05-08
Abstract: 557,224. Pulling-over machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). May 8, 1942, No. 6212. [Class 17 (i)] In a machine of the kind described in Specification 12304/03, [Class 17], the pull on the upper by the side grippers is supplemented by a series of rapidly repeated pulling motions, a fluid operated mechanism providing a progressive increase of force to a predetermined maximum. Side grippers 4 connected to up-draw levers 8 and cam-operated, yield being provided by springs 16, are constructed as usual. The supplementary pull is given by yoke-members 64 actuated by a member 62 swivelling in a block 60 on a rock-shaft 58 actuated by a piston 36 in a cylinder forming part of a container 30. A second piston 34 is constantly reciprocated. Normally, a valve 80 is open, and the liquid circulates idly through a passage 78. A latch 104 engages a spool 96 to hold the valve open, and is released near the end of the first stage of the cycle. The valve is opened by a lever 102 when the machine is restarted after the usual stop for the inspection of the upper, a cam 136 actuating a link 132 to swing the lever 102. Each rise of the piston 34 produces a pull on the side gripper levers, the suc ceeding descent of the piston drawing fluid past a valve 122. The pressure in the cylinder rises until an adjustable spring 92 yields to open the valve 80. Specification 1866/12, [Class 17 (i)], also is referred to.

Abstract: 199,772. Parsons, Sir C. A., and Rosen, J. March 3, 1922. Field magnets.-In a dynamo rotor, the bonding strips used to bridge the gap and carry the eddy currents between the rotor body and end cap are shaped locally to fill the clearance space between these two parts. In the form shown in Fig. 2, the strips i, which are placed in the rotor slots between the conductors e and the keys d<1>, are bent up at h to fill the gap at the joint between the cap f and the ends of the rotor and keys. The strips i, which may also serve to bond together the component pieces of multiple-part keys, may be bent with an upward cusp to fit the gap before insertion or may be formed in situ by deforming a plain strip. The approximately triangular space in the cusp may be fitted with a piece n, and in an alternative form a strip compounded of a flat and a cusped strip is employed. In the form shown in Fig. 7, the bonding strip s is solid with an integral cusped ridge t shaped at u to fit the gap between the keys d<1> and the local slots p in the end cap f. The strips may have different conductivities along their length, the maximum being at the region where they cross the gap. Thus, the main part of the strip may be of copper united by brazing or soldering to a silver part where it crosses the gap.
