Title: Improvements in or relating to fluid-pressure-actuated electric switches
Filed: 1946-03-01
Abstract: 608,797. Engine stop-gear. TAYLOR, J. L., and TAYLOR, A. E. March 1, 1946, No. 6341. [Class 122 (iv)] [Also in Groups XVIII, XXVII and XXXVII] A double-throw switch for closing a circuit to sound an alarm and to give a visual signal on the failure of the cooling or lubricating system of an engine or when liquid in a tank falls below or rises above a predetermined level, is actuated by the movement of a diaphragm and piston which are normally subjected to the fluid pressure of the system. Fig. 6 shows the switch actuating means and Fig. 7 a view of the switch. An inlet 21 leads from the cooling or lubricating system &c. to the lower compartment of a chamber 18 which. is divided by a diaphragm 20. Resting on the diaphragm is a piston 24, the rod 26 of which passes loosely through a sleeve 27 which engages the dolly 38 of the switch. A washer 30 and spring 31 are placed over the lower end of the rod which is pressed downwards by an adjustable spring 28. A manually-operated trigger 51 is provided. The fluid pressure under the diaphragm 20 keeps the piston and steove 27 in the raised position, whereby one moving contact of the switch is maintained in engagement with the corresponding fixed contact and a circuit is closed which illuminates a green lamp. When the fluid pressure fails, the diaphragm and piston are lowered and the switch is closed by a permanent magnet 41 which attracts an armature 40 on the movable member of the switch. The contacts controlling the green lamp are thus opened and a second pair closed to complete a circuit through an electromagnetically operated horn and through a red lamp. Fig. 7 shows the switch which consists of a pivoted arm 37 carrying a flexible crosspiece 42 carrying a contact at each end. The contact 43 at one end is on the top surface of the cross-piece and engages a fixed contact 45 when the dolly 38 is lowered. The contact at the other end of the cross-piece is on its lower surface and engages a second fixed contact when the contacts 43, 45 are separated. The arm 37 carries an extension in the form of an iron plate 40 which is attracted and held by a permanent magnet 41 when the dolly 38 is not held in its raised position by the sleeve 27. The magnet also causes the switch to operate with a snap action when the dolly is raised. Fig. 3 shows the circuits when three switches 17 are used, of which one is inserted in the lubricating system, the other two being in fresh water and salt water cooling systems. When the three systems are in normal operation, three green lamps 13, 14, 15 are illuminated. Failure of any one system causes the corresponding green lamp to go out and a red lamp 12 to be lit, a horn 11 being sounded at the same time. A separate switch 16 is provided to disconnect the horn.

Abstract: 101,072. McNaughton, J. May 15, 1916. Stereotype.-In apparatus for casting stereotype plates, the casting-box and melting-pot are connected together and pivotally mounted so that they can be turned to allow the metal to run in sheet form direct from the pot to the box. The matrix is in dished form to obviate routing of the edges of the cast-plate. As shown, the bottom plate 9 of the casting-box and the melting-pot 10 are integrally connected and are pivotally mounted on a shaft 4 carried by a support 1. An arm 5 of the support is provided with a stop-projection 6 and a notch 7, in which a lug 18 on the pot 10 engages to hold the apparatus in the horizontal position. The plate 9 is slidable laterally on the shaft 4 to withdraw the lug 18 from the notch 7. The pot 10 is formed with a flat inclined part 11, the upper edge of which is of practically the same width as the casting-box. The matrix M is of dished shape, having flanges N on the sides and one end, and the flanges resting on a raised rim 12 of the bottom plate 9. The other end of the matrix is adapted to be forced into a transverse groove 14 of the casting-box by means of a pivoted clamping-bar 15. The flanged edges of the matrix are clamped by the removable-cover plate 20. A sheet 0 of paper is placed between the matrix and cover-plate. To obtain a more even cooling of the cast-plate, the end of the bottom 9 adjacent to the pot 10 is thinned out centrally by forming it with a recess 17.

Title: Improvements in or relating to machines for automatically performing a finishing operation on a marginal portion of an unattached shoe sole
IPC: A43D95/22
Filed: 1941-05-30
Abstract: 550,285. Finishing soles. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). May 30, 1941, No. 6920. [Class 17 (i)] [Also in Group VIII] A machine for burnishing and/or trimming the edges of unattached soles has a feeding wheel at an angle to the direction of feed so that the work is pressed against the tool and is automatically controlled by solenoids so that the pressure at different parts of the sole is varied to correspond with its thickness at the part undergoing treatment. The feed wheel 12 has teeth which are laterally curved on both front and back faces and have sharpened edges. It is mounted on a driven spindle in a bearing 40 pivoted at 42 and is pressed toward the work by an adjustable spring 64. The sole S rests on a driven circular table 10. A presser foot 16 may be provided. An adjustable stop 70 limits the descent of the feed wheel when no work is present. The tool comprises a lower part 114 and an upper part 116 each having axially projecting portions which interfit to form a working surface 118 of variable width. The lower part rests on a collar 128 secured to a driven shaft 86 and is bored to receive a pin 132 causing the tool to rotate with the collar. The upper part is urged downwardly by a spring 220 and gravity, so that the height of this part is a measure of the thickness of the work at the point of operation. A micromatic switch controlled by a plunger 212 actuates a solenoid 178 to raise the corresponding end of a lever 152 when the fore-part of the sole is reached. The lever depresses a strap 150 having a forked lower end engaging the bearing 40 to increase the pressure on the sole. The spring 220 is carried on a lever actuated by a second solenoid 238 controlled by a second micromatic switch 252, the arrangement being that when the fore-part of the sole is being operated on the pressure on the feed-wheel is produced by the spring 64 and the solenoid 178 acting through the lever 152 and strap 150, whereas when the thinner shank is under treatment the strap 150 is raised to inoperative position and the spring 220 is depressed to cause the two parts of the tool to close together. The tension in the leaf spring 220 is relieved when the solenoid 178 again comes into action. To prevent the switch 250 being actuated by descent of the bearing 40 when no work is on the tables 10 the plunger 252 is carried on a lever and depressed by rise of a lever 262 secured to the bearing.

Abstract: 1,078,776. Feeding record tapes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb. 18, 1965 [Feb. 21, 1964], No. 7065/65. Heading G5R. [Also in Division H2] Record tape 1 is driven by spindle 4 associated with pressure rollers 10, 11, and coupled to flywheel 12 and motor 13. Push-buttons 14, 15, 16, control the fast forward,- normal forward, and reverse operations of the motor respectively, an interlocking device 30 ensuring that only one button is effective at a time. If an operation of the motor is interrupted by actuating one of the buttons, the pressure rollers are disengaged from the tape and switch 28 opens the motor supply circuit. While the motor is decelerating, it energizes electromagnet 24 of lock 22 so that member 25 retains the buttons 14, 15, 16, by cams 26. It is not until the motor has stopped that the lock is released and further operation of the motor can be initiated. Separate members may be provided for controlling the motor and the pressure rollers respectively, these members being associated with switches in circuit with a lock-operating relay which is maintained energized by the motor voltage during the run-down period. Alternatively, the relay may be de-energized during the run-down period, for energizing the lock through normallyclosed contacts. The operating member for controlling the pressure roller may be held in an operative position by an electromagnet against the force of a spring, the electromagnet also serving to lock the operating member. In a further embodiment, the locking arrangement comprises a transistor whose input circuit includes a capacitor and the base of which is D.C.-coupled to the collector of a further transistor of the same conductivity type. The motor voltage is applied to the input circuit of the last-mentioned transistor for controlling a lock-operating relay.
