Title: Improvements in or relating to toy animals or the like
IPC: A63H13/02
Filed: 1925-07-04
Abstract: 258,963. Logan, H. T. July 4, 1925. Mechanical toys.-A toy animal, bird, seal or the like comprises a part such as the head which is movable substantially horizontally with respect to the body of the animal and upon which a coin or biscuit can be laid, a retaining member such as the lower jaw situated below and movable with the movable part, and an actuating device for causing the movable part to recede sharply from, and return immediately towards, its original position, in such time as to permit the coin or biscuit to fall and be caught by the retaining member during the return movement. The head 11, Fig. 1, of a toy dog is connected to the body portion 13 by means of two parallel-motion links 17, 18. The lower jaw 12 of the dog is pivoted to the link 18 and is normally held in closed position by a spring 21. An extension 23 of the link 18 is connected bv means of a slotted link 24 to one arm 28 of a spring-actuated bell-crank lever 29 mounted on a pivot 31. The other arm 40 of the lever 29 is provided with a pin 41 upon which a rod 42 is pivoted. A pair of bellows 45 and an operating lever 51 are provided at the base of the body part, the tail 14 being formed integral with the projecting end of the lever. In operation, the tail 14 is depressed, thus collapsing the bellows and, through the rod 42, causing the lever 29 to rotate into set position, in which position it is held by a detent lever 46. As the lever 29 rotates, a pin 27 on the lever slides in the slot 26 of the link 24 so that the bead is not caused to move. The bellows, which act as a retarding device, in opening, trip the detent lever, thus allowing the lever 29 to return sharply to its initial position under the action of the spring 30. During the first part of the return movement, the pin 27 is held at the base of the slot 26 by means of a catch-member 25, and the head is drawn backwards. During the second part of the return movement the link 24 is in tension and the head is returned to its normal position, the mouth being caused to open by the inertia of a weight 20 depending from the jaw 12. A throughway 58 is provided to allow the coin or biscuit to pass from the mouth into the body part. In a modification, Fig. 4, the lever 29 is replaced by a toothed wheel 61 actuated by a continously rotated pin wheel 62. A sound-producing device may be provided to emit a bark or squeak during the movement of the parts.

Abstract: 1,044,419. Container closures. CONTINENTAL CAN CO. Inc. April 26, 1965 [May 21, 1964], No. 17495/65. Heading B8T. A cap 15 is partially coated on the inside with a plastics-like compound 23 so that when an anvil 24 presses the cap on to a container rim 11, the plastics-like compound flows and sets to form embossments which mate with discontinuous thread portions 20 on the container rim. A punch 25 slightly bends a curled rim 19, formed to make rigid the cap, which is preferably metal, into a neck 12 of the container 10. A cam surface 21 on each of the thread portions 20, presses against the embossment formed by the hardened plastics-like compound to force the cap upwards when it is unscrewed. The plastics-like compound is preferably a plasticized polyvinyl chloride plastisol containing gas bubbles and known as a puffed or foamed plastisol, but rubber, synthetic rubber, foam polyurethane or foam polyethylene &c. could also be used. If the seal has to be made at a temperature higher than room temperature, plasticized polyvinyl chloride or polyethylene or hot melts could form the basis of the sealing compound. In a modification, Fig. 3 (not shown), the curled rim 19 is not bent into the container neck 12 and the cap 15 is held in place by the plastics-like compound alone. In a second modification, Figs. 4, 5 (not shown), a lower section 31 of the cap is cylindrical and the rim 32 is curled inwardly. A thick fillet of plastics-like compound is formed over the lower part of the discontinuous threads 36 embossed on the container rim 35 and the curled rim 32 may be bent into the container neck 34. In a third modification, Figs. 6, 7 (not shown), both a section 43 of the cap adjacent the top and a section 45 adjacent the curled rim are cylindrical. Continuous threads 50 are embossed on the container rim 49 and merge smoothly with a cylindrical portion 51 of the container rim. The plastics-like compound flows over the entire length of the rim 49 and also into the curled rim 46 of the cap 40 to cover its edge 53.

Title: Arrangement for connecting interior parts of electricity meters together and with a support inside the casing
IPC: G01R11/04
Filed: 1946-06-12
Abstract: 613,235. Making cores for electric meters ; riveted joints. LANDIS & GYR SOC. ANON. June 12, 1946, No. 17568. Convention date, June 21, 1945. [Classes 83 (ii) and 83 (iv)] [Also in Group XXXVI] An arrangement for interconnecting interior components of electricity meters with each other and to a support within the casing comprises a moulding of fishplate type having upsettable edges and a superimposed riveting- device, the moulding being adapted to hold together a series of grooved laminated plates by insertion into the groove and upsetting of the upsettable edges, and the riveting-device being adapted to hold the series of laminated plates thus held together to a support within the casing provided with holes adapted to receive the rivets. A solid member 1, Fig. 1, of elongated fishplate type, is produced by stamping or casting, the ends 2, 3 representing upsetting-surfaces. The member 1 has a top piece forming two rivets 4 and a reinforcing web 5. The member may be deep drawn from a blank, in which case the rivets 4 and web 5 are hollow. The laminations 7, Fig. 4, forming the magnet of a meter are formed with undercut recesses both on the side adjacent to the support 8 and on the side adjacent to the pole piece 9. Grooves 10 are thus formed in the pack of laminations into each of which a member 1 is slid so that its ends 2, 3 project slightly. These ends are then upset so as to clamp the laminations together to form the core pack. The carrier plate 8 and the pole pieces 9 are drilled to take the rivets 4, the holes being slightly countersunk on the side remote from the core. The rivets 4 are inserted into the holes and are upset into the widened ends so as to rivet the plates 8, 9 to the core 7. If the members 1 are solid the rivets may have a conical recess 11, Fig. 5, on the upper end into which a taper punch 12 can be inserted to splay out the rim of the rivet head 4 and force it into the countersunk portion of the hole. When the member 1 is deep drawn the heads of the rivets 4 may be perforated so as to leave only a small flange. An upsetting-tool 13, Fig. 6, is inserted into the perforation and upsets the ends of the rivets. Whether solid or stamped, the fishplate portions of the members 1 may be chamfered so as to fill up the grooves in the core in the direction in which the tool used for upsetting the rivet heads acts. A brake magnet for an electricity meter may be laminated and the laminations similarly held together and riveted to the support in the casing of the meter.

Abstract: 750,241. Discharge apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. June 15, 1954 [June 26, 1953], No. 17726/53. Class 39 (1). [Also in Group XXIV] A mechanism for adjusting the axial spacing between two electrodes in an electron discharge device comprises an actuating member and a pair of levers which operatively engage said actuating member on both sides of the centre of said member, said levers being rigidly connected to arms which engage with an adjusting member, the arrangement being such that on movement of said adjusting member said levers are turned about their pivots and cause movement of said actuating member. The mechanism is shown attached to a klystron valve of the type described in " Proceedings of the Institute of Electrical Engineers," Part IIIA, No. 18, 1952, pages 445-452, the envelope of which comprises a first section 1 housing an electron gun and part of the cavity resonator including one resonator aperture, and a second section 2 comprising the second aperture of the resonator and a reflecting electrode, the two sections being joined by a flexible wall which also completes the cavity of the resonator. A metal support 3 is secured to envelope portion 1 in a plane parallel to the grid covering the resonator aperture, and an actuating member in the form of a collar 4 is secured to the envelope portion 2 at a position above the flexible wall, the support 3 and collar 4 being urged towards each other by springs 6 mounted on bolts 5. Two levers 7 each comprising a planar portion and an arm 8 are pivoted on balls 9 mounted in shallow depressions in the support 3 and engage the underside of the collar 4 by way of balls 9a. The lever arms 8 engage a conical surface 10 formed at the end of a screw-threaded adjusting member 11 mounted in a co-operating threaded member 12 on the support 3. Rotation of the adjusting member 11 moves the conical surface 10 axially between the arms 8, thereby changing the spacing therebetween so that the planar portions of the levers 7 pivot about the balls 9 and effect a change in the spacing between the collar 4 and support 3. Extremely small relative movements can be obtained by suitable positioning of the balls 9 on the support 3, and a reduction gearing may be associated with the adjusting member 11. The member 11 with the conical surface 10 may be replaced by a cam member positioned between the arms 8 and rotated by a suitable adjusting member.
