Abstract: 1,001,764. Convertible seats. P. FANCHANEL & CO. Ltd. July 31, 1964 [July 29, 1963], No. 3659/63. Heading A4J. A convertible armchair similar to that disclosed in Specification 933,065 in which the chair is converted into a settee having the chair seat 66 and chair back 67 forming the settee seat, and the chair arms 59, 60 forming the settee back, also has two frame parts 1, 2 hinged together and locked in the armchair position by a catch 44 operable by lifting the arm 59 from its armchair position. The catch 44, Fig. 1, which is pivotally attached to a rectangular arm base connected to the frame 2, has a pair of arms 45, 46 whose hook-shaped ends 49, 50 engage the side 11 of the frame 1 in the armchair position by the pressure of the arm 59 upon a bridge 47 of the catch 44. The chair is converted to a settee by lifting arms 59, 60 so that their upper surfaces are held in a horizontal position by strips 51-54 and the catch 44 is released, pivoting frame 2 about hinge 39 until the arms 59, 60 are aligned, and lifting and pivoting the chair back 67 down until it rests upon the upper surface of a box 127, which forms a limb 21 of the frame 2. In the chair position the seat 66 is supported on balls 96, 97, 100 and the end 118 of an arcuate plate 117 with the ball .100 raised level with ball 96 so that the seat slopes down towards the back 67. However, in the settee position the seat 66 and back 67 are inclined downwardly towards the arms 59, 60, by the ball 100 being lowered automatically under the action of spring 123, Fig. 2, upon pivotal movement of frame 2, and by the box 127 assuming the chaindotted line position 131 under the weight of the back 67. Pivotal movement of the frame 2 to the settee position displaces rod 112 and thus removes the end 111 of plate 106 from aperture 104, allowing the rod 101 bearing the ball 100 to be lowered. Specification 933,065 is referred to.

Filed: 1952-02-13
Abstract: 709,238. Unpacking. AUTO-DAIRY ENGINEERS, Ltd. Feb. 12, 1953 [Feb. 13, 1952], No. 3769/52. Class 94 (1) [Also in Group XXX] In apparatus for discharging empty bottles from crates, the crates are fed to a runway over which they are traversed upside down by a travelling band, the bottles falling through a slot in the track into a rotary drum by which they are inverted and discharged on to a conveyer, the empty crates passing over the runway to a delivery shoot. As shown, inverted crates of empty bottles placed upended on a platform A<SP>1</SP> with their open tops and the bottle mouths in contact with a track A, are fed up along the track by rods a<SP>1</SP> extending between a pair of endless chains A<SP>3</SP>. When a crate reaches a slot a in the track, the first row of bottles falls into a compartment d<SP>1</SP> in a drum D which is then rotated on its shaft d to bring a second compartment under the slot a as the second row of bottles falls through and so on until the crate is empty. A rubber sleeve d<SP>2</SP> on the shaft d forms the base of each compartment and cushions the fall of the bottles. The bottles are prevented from falling from the compartment d<SP>1</SP> as the drum rotates by a track D', but on reaching the end of this track the bottoms of a row of bottles fall into a niche d and are upended upon a conveyer C<SP>2</SP> by a wall d<SP>4</SP> as the drum rotates. Meanwhile the empty crate travels on over the track A to a shoot B, being inverted by engaging a rod b. Further down the shoot, the crate engages a pin b<SP>1</SP> and is turned through 90 degrees before being delivered to a conveyer C. If a bottle becomes jammed as it leaves a crate, it engages a plate g secured to a pair of pivotally mounted arms G, so as to rotate these arms and through a lever g<SP>1</SP> actuate a switch G<SP>1</SP> to stop the motor D<SP>2</SP> driving the chains A<SP>2</SP> and the drum D.

The dotted lines 35 indicate the distortion when the beads are spread to fit the rimflanges 49, the broken lines 36, 37 indicating the cross-section of the tyre when inflated, and fully loaded, respectively. The tyre is preferably fitted to a wheel having outer discs streamlined with the side-walls of the tyre. To this end, the beads may be formed with overhanging lips 32. The wheel shown in Fig. 1 comprises a pair of discs B fitted with a well-base rim, and outer fairing-discs 46, 47, rubber packing - rings 48 being fitted at the edges of the rim. Fig. 6 shows a modification in which a separate air-tube is dispensed with by providing soft rubber facings on the beads 56 which are gripped between the flanged edges 57 of the wheel discs and clamping-rings 58. Fairing-discs 60, 62 are secured by spring- clips 61 and a spring-ring 63 respectively. In building-up the tyre casing, the individual cords are laid so that their angles to radial lines increases from the beads to the tread, as indicated in Fig. 11. In all cases, the rubber insertions between the plies are thicker in the tread zone than in the side-walls, and an additional rubber cushioning layer may be fitted on the inner ply under the tread.

[Class 27] [Also in Group X] A miniature coin-freed shooting-range comprises a front member B, Fig. 1, supporting the firearm, a rear member A containing the target, and a connecting tunnel C through which the bullets pass, and is provided also with electrically operated signalling devices and prize-delivery means, the circuits of which are closed by a bullet passing through the centre of the target. In the construction shown, the member B is fitted with a support for the firearm, with coin-freed apparatus for the delivery of the bullets, and with shoots and receptacles for delivering the bullets and prize discs or tokens. The member A has an upper and a lateral slot for the insertion of the targets, and is fitted, in line with the tunnel, with a cylindrical member 1, Fig. 8, of sheet metal. This member terminates, at its forward end, in a disc 2, to which is secured a lead washer 3 against which bullets may impinge. The target is adapted to be mounted in guides 4 arranged behind a central opening of the member 1. A bullet which passes through the centre of the target passes also through an opening 6 of a flat box 5 and impinges against a buffer 7 fitted to the end of a spring-controlled plunger 8. The rearward movement of the plunger closes a switch for operating a visual or audible signalling device, the duration of which is prolonged by means of a dash-pot 19. The closing of the switch also energizes a pair of electromagnetic coils adapted to tilt a device which projects into the shoot containing the prize tokens and which, when tilted, releases one token. The latter falls into an accessible receptacle provided on the front of the member A. The boxes of bullets are stored in a pair of tubes 73, Fig. 14, and are delivered one at a time to the marksman by slides 76 actuated by a hand lever 27. The lever is normally held locked by a detent 81. When a coin 77 is introduced, it passes through a shoot 75 and eventually rests on a plate 79. In this position it closes a circuit to energize a pair of electromagnetic coils 80 which attract the detent 81. The hand lever, thus freed, is moved to the right or left and a box of bullets is moved by one of the slides 76 into a delivery shoot 82.
