Title: Improvements in and relating to automatic feeding mechanism for use in machines for making incandescent lamp bases and the like
IPC: H01J9/46
Filed: 1920-03-06
Abstract: 164,149. British Thomson - Houston Co., Ltd., (General Electric Co.). March 6, 1920. Feeding articles in predetermined attitude from hoppers and shoots.-In a machine for making bases of incandescent electric lamps and similar devices comprising moulds 1 mounted on a carrier 2, the contacts are fed automatically from a pair of receptacles 24 to a guideway 50 leading to a mould and are finally pushed into position over the mould by a reciprocating member mounted in the guideway. The contacts, which are in the form of eyelets, are forced through holes 31 in the wall 25 of each receptacle by brushes 34 carried by a rotating head 35, Figs. 1 and 4. A transverse partition 36, Fig. 1, placed in front of the holes 31 deflects the contacts on to the inclined walls of the head 35, from which they slide towards the space in front of the partition, tending to right themselves in doing so. Overturned and excess contacts are swept past the holes by the brushes, the remaining contacts passing through the holes with the right side uppermost into passages 33, Fig. 3, leading from each receptacle. The bottoms of the passages are formed by rotary plates 32, 44 which feed the contacts to the ends of the passages. One contact at a time is transferred from the end of each passage to the guideway 50 by means of a reciprocating slide 49 or 49<1>. The pair of contacts, one from each passage, is then pushed forward along the guideway by means of a reciprocating member 51 having a slotted nose shaped as shown in Fig. 11. In its forward movement the nose of the member 51 engages a block 54 slidably mounted in the guideway in order to maintain the contacts firmly in their seats. Towards the end of its movement the underside of the member 51 engages a supporting slide 12', Fig. 7, and pushes it over a hole 56 in a support 27<1>. The hole 56 is placed directly over the mould which is in position to receive the contacts. While the contacts are supported over the moulds by the slide 12', the bottom die 7 of the mould and a pair of pins 9 are moved upwards by cam devices and the pins pass through slots in the slide and engage the eyelet holes in the contacts. On the return movement of the member 51 the slide 12<1> is returned to its normal position by a spring 58, and a bent rod 60 fastened to the member 51 returns the block 54. The contacts are carried downwards with the pins and drop into position on the bottom die. The member 51 and the reciprocating slides 49, 49<1> are operated by eccentrics 53, 64 mounted on the same shaft. The mould carrier is given a step-by-step movement by means of a notched wheel 21, rotary arm 22, and a pin 23, Fig. 1. The gear wheel 73, Fig. 7, driving the eccentrics, is normally clutched to the eccentric 64 by a spring key 74. When it is desired to render the feeding mechanism inoperative, the clutch is thrown out of engagement by means of a lever 75, Fig. 3.

Title: Improvements in the manufacture of rear axle casings for motor vehicles and like articles, and means for use therein
IPC: B21D53/90
Filed: 1928-03-08
Abstract: 306,721. Owen, A. E., and Scott, A. C. ' March 8, 1928. Shafts and shafting.-In the manufacture of rear axle casings from a tube by forming oppositely disposed longitudinal slots therein and opening out the slotted part of the tube by suitable internal and external tools to form the transverse annulus, the metal at the ends of the slots is thickened. by exerting heavy pressure thereon to counteract the thinning which takes place when the annulus is formed. The tube A formed with the longitudinal slots B somewhat narrowed at b is supported between a fixed block and a movable block C clamped thereon by hydraulic pressure, a bar E with rounded edges engaging in the slots and in openings in the blocks. The ends of the tube are then subjected one after the other to pressure by hydraulically operated heads F whereby the ends of the slots are brought to the rounded shape of the edges of the bar, as shown by the broken lines G, and the metal at these places is thickened. After this operation the tube ends are reduced in diameter and the slotted part spread to form the flanged annulus in well known manner. In the modification shown in Fig. 3 the ends of the slots are thickened up after the tube ends have been reduced in diameter, one end being held in a die K with a central opening tapered at T to fit the taper portion H and reduced at J to receive the tube end. The slots B are engaged by a tool L with a head Q shouldered at R to engage the ends of the slots and terminating in a part S the width of the internal diameter of the tube. Projections P on the tool are engaged by vertical members M of a head 0 actuated by a hydraulic or power press.

March 5, 1930, No. 7209. Convention date, Sept. 9, 1929. [Class 39 (i).] Means for supporting a discharge device consists of a casing surrounding a part of the device and containing a divided annular member provided with means to enable it to be moved into and out of engagement with the device. As shown in Fig. 1, a flange 22 on a jacket 13 receives a removable ring 24 with a rubber gasket 25 on which a flange 12 on the anode 11 rests. A split ring 30 engages with the other side of the flange 12 and is clamped thereon by rotation of a closure member 27 having a ridge 32 engaging with a groove in the ring. The ring is provided with pins 33 extending through the casing whereby the parts of the ring may be withdrawn to allow of removal of the discharge device when the pressure from the closure member is relaxed. The jacket is provided with a partition 17 as described in Specification 321,446, [Class 39 (i), Electric lamps, Arc &c.]. In the arrangement shown in Figs. 5 and 6, the parts of the split ring 36 are removed from the anode automatically when the movement of the closure member is reversed. Each part of the ring is provided with a slotted extension 37 formed with a groove 38 fitting over a straight rail 39 on the flange 22. The closure member 27 has a wide groove with the walls inclined to receive a compressible ring 41 carrying two pins 42. Rotation of the member 27 causes the pins to slide over undercut fingers 44 on the extensions 37, and to bear against the edges 45 so as to move the parts of the ring inwards to the anode flange. Further rotation causes the ring to slide in the groove ; the pins 42 are lowered into slots in the extension 37, and a ridge 32 on the member 27 bears against the split ring and clamps it against the flange. Rotation of the member 27 in the reverse direction relieves the pressure on the flange, and the pins move the slotted extensions along the rails so that the discharge device may be removed. The ring 24 is secured by the tapered ends of screws 46.

Abstract: 655,272. Telephone instruments. MINISTER OF SUPPLY. March 10, 1948, No. 7407. [Class 40 (iv)] [Also in Groups XL (b) and XL (c)] A mechanically resonant vibrator, forming part of the terminating condenser of a highfrequency resonant circuit comprising distributed inductance and capacity (see Group XL (b)), and arranged to be frequency modulated at the resonant frequency of the vibrator, comprises a metal diaphragm carrying a conductive sleeve which lies in an annular gap in a pot-magnet (Fig. 1, not shown). A.C. excitation for the magnet is preferably provided by a circuit having the vibrator as its frequency determining element. In another embodiment, Fig. 2, the diaphragm comprises a coned disc 25 and girder-stiffeners 26 and carries a moving coil 28 in the field of a D.C. energized magnet 20, 21, 22. The diaphragm is supported by radial tubular springs 29 which may act as feed-pipes for a gas or liquid cooling medium. A.C. power at the resonant frequency of the vibrator system is fed to the moving coil by flexible leads or by conductors passing through a tubular supporting spring. The diaphragm may be driven by a soft iron armature adjacent to the poles of an A.C. energized laminated core (Fig. 3, not shown). Fig. 4 shows an arrangement in which a die-cast or spun unit 39 supported by leaf-springs 40 carries an eddy current sleeve 36 moving in an annular gap of a laminated core 37 excited at the resonant frequency of the system. The resonant frequency of the vibrator can be varied by changing the effective restoring force of the spring suspension, the effective length of the supporting members or by changing the mass of the oscillatory assembly. The oscillating mass may be increased by inflating a metal capsule attached to the oscillating assembly and fed from a liquid supply pump. Specification 655,271 is referred to.
