Title: Improvements in Mechanical Toys.
Inventor: BROWN THEODORE
IPC: A63H3/36
Filed: 1917-04-20
Abstract: 115,068. Brown, T. April 20, 1917. Mechanical toys.-Relates to mechanical toys actuated by flowing sand &c., and includes arrangements by which facial &c. effects are produced. In the arrangement shown, the body part of a figure representing a clown is formed of a flat box A with two compartments E', E<2> communicating by a narrow channel. The body is mounted on pivots K on a stand N, D representing legs and is provided with pivoted arms B. Openings G, F covered by transparent material represent the eyes and tongue and colour effects are marked on the rear wall of the body or a plate carried behind the front wall. The toy is inverted so that the sand passes into the compartment E' and is then placed in the position shown when the lower part of the body engages stops M on the stand. The sand flows by gravity into the lower compartment and at a certain stage leaves uncovered the coloured back, causing a change in the appearance of the eyes &c. Finally the weight of the sand tilts the head forward so as to throw down the arms and cause the figure to fall forward. It is stated that, after falling forward, the figure rolls on to its back and a rear projection Q strikes the ground and produces other evolutions. In modified forms, a bird or other figure is mounted on a fixed bar on which it turns.

[Class 57] A centrifugal governor for use with a fuel injection pump comprises weights 4 loaded by a spring 5 and actuating a sleeve 9 connected to a lever 21. The sleeve 9 is also loaded by a light spring 22 which controls the idling speed. A spring 23 engages a plate 25 and stops 27 and a shorter spring 24 rests on the plate 25.

Planting-machines.-Potatoes contained in a hopper 2 are lifted by cups 12 on an endless chain 9 and delivered into a tube 39 fitted with trap-doors 42, 43 controlled by levers so that when one door closes the passage through the tube the other is in the open position. A shaft 26 is carried below the tube 39 in a frame 17 supported on pivots 16 and is intermittently driven from the main countershaft 3 through a chain 14, sprocket wheel 15, and a mutilated pinion 22 meshing with a pinion 27 on the shaft 26. The shaft 26 is locked, while the mutilated portions of the pinion 22 pass the meshing point, by projections a secured to the pinion 22 engaging in recesses between projections b on the shaft 26. The member 28 carry. ing the projections a is also provided with pins 51 to engage levers 46, 47, operating the trapdoors. The shaft 26 carries arms 37 with pins 38 and the mutilated portions of the pinion 22 are so arranged that each arm pauses below the tube 39 for a short time in its rotary movement, the lower trap door being opened simultaneously to permit a potato to fall on the upturned pins. The potato is carried round on the arm 37 and is removed therefrom by a swinging forked member 57 also operated by the pins 51 on the member 28. The potatoes fall into a tube 62 whence they pass to the ground, their passage through the tube being controlled by a trapdoor 63 actuated by a cam member on the shaft 26. The potatoes in the hopper are agitated by a shaker 71 which is given its motion by a cam on the shaft 3.

Title: Improvements in and relating to a machine for helically winding metal sheets or plates in particular for producing tubes
IPC: B21C37/12
Filed: 1956-03-01
Abstract: 791,046. Coiling helically jointed tubes; welding by pressure. COMPAGNIE DE PONTA-MOUSSON. March 1, 1956 [March 7, 1955; June 21, 1955; Feb. 6, 1956], No. 6434/56. Classes 83 (2) and 83 (4). A machine of the anvil and punch type for producing tubular objects, such as pipes, by helically winding metal sheet or plate is characterized in that the punch simultaneously effects the feeding and the bending of the sheet. Metal sheet t is guided by roller means G to a polished cylindrical anvil 5, extending from a block 5a and cut away at 5b, on to which it is bent and helically around which it is simultaneously fed by a concave faced punch 6 reciprocating along an axis Y-Y offset from the anvil axis. The punch 6 is guided by a roller slide 20 and is carried by a double-acting hydraulic piston 7,' the supply of fluid to which is controlled by a cock 11 the key of which is secured to a plate 16 oscillated by a link 18 from a motor 19. The tangential component of the bending force feeds the sheet around the anvil 5 to pass between the bottom face of the anvil and a polished die 4. The thus-coiled tube T is guided by rollers 22, rotatable about axes perpendicular to the tube axis, in a ring 21 itself rotatable on balls 23 in a fixed frame 24. The frame 24 carries an electrode 25 for welding the helical seam. In a modification, Fig. 5, the anvil 5, which is of part cylindrical shape, lies above a punch 34 carried on a plate 35 reciprocated by a crank-plate 42. To join two sheets end to end for coiling, the inner weld bead on the upper face of the sheet may be effected at the input side of the machine and the outer weld bead at the output side of the machine. In another modification, Figs. 9, 12 and 13, the guide ring 21 is dispensed with and the tube is spot welded as it is formed. An electrode 46 spring-mounted on the output end of the punch 6 co-operates with an electrode 52 in the anvil 5. The electrodes 46, 52 are connected to the secondary winding 51 of a transformer Tr, to the primary winding 55 of which current is supplied on closing a switch 57 operated by a relay 58 upon the closing of a further switch 60, 61. The switch 60, 61 is closed by a boss 62 on the oscillated plate 16 so that a weld is effected at the end of each stroke of the punch 6 towards the anvil 5. The guide ring 21 may be rotated by a motor. The axis Y-Y of the punch 6 may be oriented in any direction. The punch 6 may be actuated by several rams.
