Title: Toy cap gun
IPC: F41C3/08
Filed: 1960-10-07
Abstract: 903,216. Toys. MARX & CO. Ltd., LOUIS. Oct. 7, 1960 [July 22, 1960], No. 34499/60. Class 132 (3). A toy gun comprises a barrel 12, a bullet support 14 aligned with the barrel and having a passage 16 therethrough for propellant gas, an anvil 20 behind the bullet support, a hammer 22, a trigger 30, means to hold a cap at the anvil, the anvil having a hole 28 aligned with the passage, and means whereby the trigger releases the hammer to hit the cap, the bullet 32 being propelled through the barrel by the combustion gas resulting from explosion of the gas. A stud 60 on the gun pivotally mounts the hammer 22 urged forwardly by a spring 66 on the stud towards a cap strip 48 passing over a cap guide 24 from a roll on a hollow support 34. The hollow support houses a pin 76 on the gun. The pin mounts the trigger which has a side wall and bottom wall, a laterally-extending stud 80, which engages an abutment 82 on the hammer, and a rearwardly-extending arm with a pivot 86 which engages in a hole in a feed finger 26. A spring 84 engages the feed finger to urge it and the trigger forward and to pull the feed finger down. Pressing the trigger 30 moves the hammer rearwards against spring action until the abutment 82 travels past the stud 80 and is free to pivot forwardly under spring action and explode a cap on the anvil surface 20 at the rear of the bullet support cylinder. The explosive gases pass through the hole 28 in the anvil through the cylindrical passage in the bullet support 14 and propel the hollow bullet mounted on the support along the barrel. The pivot 86 on the trigger raises the finger 26 so that the edge 46 contacts the cap strip and moves it forwardly and the pawl 54 on the finger engages a ratchet tooth 52 on the cylinder mounting the supports 14 to bring the next bullet into alignment with the cap strip. The cylinder may have an end wall with apertures corresponding with the supports and may have compartments. The cylinder may pivot laterally of the gun body. A door 38 provides access to the cap roll and has an upward extension 44 for guiding the cap strip.

Abstract: 806,035. Induction furnaces. T. I. (GROUP SERVICES), Ltd. Feb. 5, 1957 [Dec. 3, 1955], No. 34683/55. Class 39(3) Electrically non- conducting materials or articles 4 are heated by contact with molten material 3 suspended freely in a levitation furnace comprising a water-cooled copper tube 1 having a reverse turn 2 at its upper end, so that when H.F. current is passed through the coil 1 the conductive material 3 e.g. conductive porcelain or a metal of high M.P. is melted and becomes substantially a sphere. Thus fibres 5 of quartz may be formed by continuously feeding a rod 4 of quartz through the material 3 or materials such as synthetic sapphire may be formed into a continuous rod. The process is carried out in a vacuum or inert atmosphere. It is stated that by providing a controllable rotating magnetic field around the furnace, it may be possible to cause the molten material 3 to assume a shape other than spherical and such that it forms a container for the material 4 to be heated i.e. the shape would be that of a bun or disc which would become saucer-shaped under the weight of secondary material placed on it

Title: Fluid flow control valve
IPC: F15B13/08
Filed: 1960-10-12
Abstract: 900,430. Valves. NEW YORK AIR BRAKE CO. Oct. 12, 1960 [Nov. 16, 1959], No. 34903/60. Class 135. A valve controlling the supply and exhaust of fluid to hydraulic motors comprises a bank of control valves, one for each motor, provided with an inlet 11, Fig. 2, and an exhaust 12. Each valve comprises a housing having twelve chambers 14 ... 19, 21 ... 26, the chambers 17 and 22 constituting motor ports leading to either side of the motor piston and each valve spool has grooves 28, 29, 31, 32 forming lands 33 ... 37, the lands 34, 36 having axial passages connecting ports 43, 44 and 45, 46, respectively. Each spool is movable to five positions 1-5, as shown, on the right-hand side. With the valves in the neutral position 3, all the motor ports are closed to the inlet 11 and exhaust 12 and to each other and fluid supplied at 11 passes through a passage 51, chambers 25, 24, 25a, 24a, 25b, 24b and an exhaust manifold 52 to the exhaust 12. When the motors are to be operated in series the valves are moved to positions 1 and 5 as shown. Fluid entering at 11 passes through chamber 21, port 46, axial passage in land 36 and port 45 to the motor chamber 22 and to one side of the motor while the other side of this motor exhausts the fluid through chamber 17, port 44, axial passage in land 34, port 43 to a passage 55a. Since chambers 15a and 22 are closed by 33a, 36, respectively, the fluid in passage 55a flows past a non-return valve 57a to chamber 18 and through ports 44a, 43a to one side of the second motor. In a similar manner the exhaust from the second motor flows through 46a, 45a to passage 55b and hence past valve 57b and ports 44a, 43b to one side of the third motor, the exhaust from the third motor passing through ports 46b, 45b and manifold 52 to exhaust 12. To operate the motors in parallel the valves are moved to the positions 2 and 4, Fig. 3, in this case fluid supplied from the inlet 11 passes through chamber 21, chamber 19, passage 53a, chambers 18a, 19a, passage 53b to chamber 21b. The fluid in chambers 21, 19a, 21b flow to the motor chambers 22, 17a, 22b, respectively, as above and the exhaust fluid from the motor flows from chambers 17, 22a, 17b to chambers 16, 23a, 16b, respectively, as above. The fluid in chamber 16 passes to exhaust 12 through either chambers 15, 14, 14a, 14b and manifold 52 or through passage 55a, chambers 15a, 16a, passage 55b, chambers 15b, 16b and manifold 52. The fluid in chamber 16b passes directly to manifold 52 while the fluid in chamber 23a flows through passage 55b, chambers 15b, 16b to manifold 52.

Title: Improvements in or relating to a feeding device in wood-screw cutting machines
IPC: B23Q7/00
Filed: 1928-11-27
Abstract: 313,141. Maschinenbau & Schraubenfabrik Akt.-Ges. June R. 1928, [Convention date]. Turning wood-screws-In a device for feeding blanks to a wood-screw cutting machine, particularly a machine having a two-spindle indexable work-holder D for turning and nicking the screwheads, the screw blanks are transferred in succession from a stationary magazine to a chucking position and removed from the chucks on completion by mechanism comprising an arm which is reciprocated in a slide mounted on the end of a cam-actuated rocking lever. The chuck spindles c on the work-holder are arranged at 180‹, the chuck at station Z2 being opened by a bar A actuated from a cam H2 and fresh blanks being inserted at this station by a pusher S actuated by a cam h1. The blanks are placed in a rotary hopper V and liffed by a picker G1, operated from the hopper spindle. The blanks then pass down a shoot formed by a pair of side walls 1 and guide rails 2, 3, and at the bottom of the shoot the blanks are checked by bolts 6 passing through a member 5 and pressed up by leaf springs 7. The member 5 is provided with ledge 5<a> this ledge and a portion of the inner wall 1 being cut away to allow the passage of the gripping arm. Longitudinal shafts 8, 10 are provided with lever arms 9, 11 actuated by cams 13, 14 respectively on the main cam shaft. The other end of the shaft 8 carries an arm 18 provided with a bushing 18<a> in which slides a rod 19 carrying the gripper support 20 and a gripping support 21. Reciprocating movement is imparted to the rod 19 in its bushing by means of a lever arm 23 mounted on the shaft 10 and acting through a connecting rod 22. The gripper consists of a central member 25a an upper member 25b and a lower member 25<c> which are pivoted on a bolt 24 and held together against an abutment 28 by springs 26, 27. In operation the gripper is moved up to the magazine and a screw blank is picked up between the upper and central members and transferred to the chuck at Z2. During the picking up of a blank from the magazine the indexing movement of the workholder takes place, and this brings a completed blank to the position Z2. The gripper is first moved to the postion shown in Fig. 9 where it grips the finished blank between the central and lower members and removes this from the chuck before passing into the position shown in Fig. 10 where the fresh blank is pushed into the chuck. When the gripper moves back to the magazine, the ledge 5<a> engages the finished screw held by the lower gripper member and ejects the screw into a receptacle. For screw-milling machines the pusher is preferably dispensed with and the shafts carrying the arms 18 and 23 are then reciprocated by cams to carry the screws into the chuck. In this case the arms 9 and 11 may either be slidable on their shafts or the cams 13, 14 may be broad enough to permit the longitudinal movement of the rollers 12.
