Title: Improvement in method and apparatus for forming and trimming die castings
IPC: B22D31/00
Filed: 1940-07-10
Abstract: 542,647. Injection-moulding machines. CROWN FASTENER CORPORATION. July 10, 1940, No. 11464. Convention date, Nov. 3, 1939. [Class 87 (ii)] [Also in Group XXII] An automatic machine in each cycle forms from thermo-plastic material a casting 30 and its gate 31 on a support 32 projecting into the die 14, moves the support 32 with the casting &c. from the die to trimming mechanism 62, which separates the cast article from the fins and gate which remain on the support, strips the gate &c. from the support and returns it to the die. A cam 23 on a driven shaft 18 opens a valve to admit compressed air, via a pipe 81, to operate a plunger 13 of a melting pot 12, thus forcing molten material into the die 14. A cam 26 on a driven shaft 10 then rotates a shaft 25, on which the support 32 is adjustably mounted, to transfer the casting &c. from the opened die to a position between a trimming die 62 and adjustable punch 57. An eccentric 22 then advances the punch to separate the casting which falls on to an incline 72 when the punch returns. The cam 26 then causes the support 32 to move to a position opposite a shoot 49, leading to the melting pot or to a container, and, while there, a cam 21, acting through a lever 44, link 40, lever 38, and rod 45, actuates a stripper 47 to remove the gate &c. which is projected through the shoot 49 by a blast of air from a pipe 50 supplied by a valve opened by a cam 24. This valve also supplies air to a pipe 71 to blow from the trimming device any trimmed particles and the casting, if it sticks. The cam 26 then moves the support 32 to its original position, the mould closes, and the operations can be repeated. Air pressure is also supplied to a container 86 from which lubricant is projected on to the die by a pipe 88.

Patent GB-115254-A (GB)
IPC: F04F1/06
Abstract: 115,254. Human, A. H., and Kestner Evaporator & Engineering Co. March 29, 1917. Direct air-pressure apparatus, automatic, aircompressing devices, applications of; valves for pressure fluid, actuation of; valves for pressure fluid, arrangement of.- Apparatus for raising liquids comprises a forcing chamber A with liquid inlet and delivery valves D, E, and with two valve seatings A<1>, A<2> for a float valve A<3> which controls the admission and exhaust of the pressure fluid. The chamber communicates by a pipe H with a chamber J which is adapted to be connected alternately to a high-pressure air chamber L or a pressure pump and a low-pressure air chamber K or a vacuum pump. Communication between the chambers J, K is controlled by a non- return valve N which is adapted to be closed by suction in the chamber K and is connected to a high-pressure valve M controlling communication between the chambers J, L. The valve-rod carries a balancing piston 0 and a weight 0'. A relief valve Q is arranged between the chambers J. K. When the valve N is open, the suction in the chamber K draws liquid into the chamber A until the valve A<3> closes the pipe H. The vacuum increases in the chamber K, and closes the valve N, and opens the valve M. The high-pressure air then passes from the chamber L to the chamber A and expels the liquid. When the valve A<3> seats at A', the air pressure in the chamber J increases and opens the relief valve Q, thereby destroying the vacuum in the chamber K and enabling the weight 0' to open the valve N and close the valve M. The cycle is then repeated. In a modification, the chamber K is connected to the suction side of a double-acting air-pump, and the chamber L to the pressure side, and the piston O is replaced by a non-return valve adapted to connect the chamber L to the atmosphere when the valve N is open. In another form, shown in Fig. 3, the pipe H is connected alternately to sources of low and high pressure air through a two-way rotary valve S connected by an arm S' to the piston T' of a servo-motor T. The piston T<1> is actuated by air derived from the high pressure chamber and admitted alternately to opposite ends of the cylinders by valves T' and pipes T<2>, T<3>. The valves T<4> are actuated by changes of pressure in the pipe H produced by the seating of the valve A<3>. The movement of the valves T<4> may be controlled by a dash-pot U or by providing a restricted passage V<1> for the passage of high-pressure air to the top of the valve.

Electromagnetic switches; electric cut-out arrangements. - In a combined electromagnetic and thermal relay a primary and a secondary winding are associated with a closed magnetic circuit, the secondary winding constituting or supplying current to a heat-responsive operating element and an operating armature being located in the stray field due to the primary winding. As shown in Fig. 1 the primary winding c is placed on a yoke b the magnetic circuit of which is completed by a U-shaped magnetic member a. Surrounding the upper limb of the member a is an annular bimetallic strip d the adjacent ends of which are short circuited by a flexible conductor e. The strip d is secured to the member a by a bracket f and its free end carries a pin j adapted on overload to move a contact h against the action of a spring p causing it to complete with a fixed contact i a circuit breaker tripping circuit. To produce a quick operation of the relay in the case of a sudden overload the contact i is carried by a pivoted armature k in the stray field from the coil c. In the modification shown in Fig. 2 the limbs r, q of the core are extended to provide an increased stray field to act upon the armature s. The armature and heat-responsive element may control separate pairs of contacts in parallel in the controlled circuit or may act upon the tripping device for an electric switch. Where the relay is used on a polyphase circuit two primary coils energized from different phases are arranged on the core so that their ampere turns add or subtract vectorially. A number of annular or helical bimetallic strips placed one within the other may be employed to increase the time element of the relay.
