Title: Improvements in or relating to control mechanisms for multiple engine units of the internal combustion type
IPC: F02D25/00
Filed: 1946-08-12
Abstract: 633,696. Starting prime movers. HOWDEN J. R. (Marmon-Herrington Co., Inc.). Aug. 12, 1946, No. 23840. [Class 38 (iv)] [Also in Groups XXVII and XXXVII] A control mechanism in combination with a number of internal-combustion engines each of which has associated with it a fuel control device for controlling the supply of fuel thereto and an ignition system, comprises a manually or foot-operable master control-member and a selector switch movable into a number of positions to pre-select any of the engines or a combination thereof for operation and to bring about energization of the ignition system or systems pertaining thereto while simultaneously establishing operating connection between the master control member and the fuel control devices of any of the pre-selected engines or any pre-selected combination thereof. Internalcombustion engines are indicated diagrammatically at 10, 10a. Each has a carburetter 12, 12a and a starting and ignition system 11, 11a. A switch 43 is arranged to connect a source of current such as a battery 56 to either or to both of the starting and ignition systems or to disconnect them altogether. A wire 37, leading to the system 11 is connected by a further wire 36 to a solenoid 26 so that the solenoid is energized when the system 11 is connected to the battery. The solenoid operates a clutch-member 30 so that an operating lever 14 of the carburetter 12 can be actuated by a rod 15 on which a foot pedal 19 is mounted. Thus the pedal can control the carburetter when the solenoid is energized. Similarly a solenoid 26a energized by the current supplied to the system 11a actuates a clutch 30a so that a lever 14a of the carburetter 12a can be actuated by the pedal 19. The switch includes two rows of contacts, one in the plane of the paper and one below it, and adjacent contacts in different rows are bridged by shoes 40, 40a. The left-hand contacts 39, 47 in the plane of the paper are connected to the wire 37 and the right-hand contacts are connected to a corresponding wire 37a. All the other contacts 50-53 are connected to the battery. In a modification, three engines can be operated either together, alone or in any combination by means of a speciallydesigned switch (see Group XXXVII). It is stated that the arrangement can be varied for the control of more than three engines. Known starting systems for starting the engine may be used. For instance the ignition circuit when closed may actuate a relay bringing about energization of an electric starter motor whereupon the relay after a predetermined time, controlled by a delayed-action relay switch, moves into an inoperative position and returns to its operative position only after the ignition circuit is broken and closed again.

Abstract: 781,349. Feeding webs. WEAN EQUIPMENT CORPORATION. Aug. 23, 1955 [Dec. 9, 1954], No. 24221/55. Class 100(1) [Also in Group XXII] In a machine in which a continuously driven feed mechanism feeds strip to a work station at which an intermittently actuated tool operates, e.g., shears, punches, forms or stamps indicia, on the strip the tool while operating upon the strip pulls the strip in the direction of feed at a speed greater than the feeding speed, and the feeding mechanism has a tension device which, allows the strip to be so pulled but which when the tool releases the strip returns it to the position it would otherwise have had. The strip 38, Fig. 5, is fed by intergeared rollers 24, 25 to a tool consisting of an upper die 17 secured in a frame 16 mounted on two continuously rotated eccentrics 15 and a lower die 19 guided in slots 18 in the frame 16 and connected by an arm to the shaft 14 of the lower eccentric 15. The dies when working upon the strip pull it faster than it is fed by the rollers 24, 25. To allow for this, the driving gear 26, Fig. 7, for the rollers is loosely mounted on the shaft of the lower roller 24 and has a projection 26a which normally engages and rotates an arm 26b secured to the shaft. When the dies 17, 19 release the strip 38 it is drawn back by the rollers owing to a spring 26c which urges the arm 26b against the projection 26a. In a modification, the arm 52, Fig. 9A, supporting the lower die 50 is mounted on an eccentric 53 which can be actuated by an electromagnetic device 56 to move the lower die to an inoperative position.

[Also in Division F2] In a fuel supply system for a combustion engine all the fuel passes through a valve device which comprises a valve element 10 loaded to the open position by a spring 14 and urged to the closed position by the pressure difference across an associated piston 2 caused by the flow through a metering orifice 12. The combined valve element and piston is located in a bore 3 in a body 1 having inlet and outlet connections 7 and 16, the former of which is connected to the delivery line of a positive displacement fuel pump driven by the engine. An extension 9 of the valve element passes through the valve port 4 and is guided in the bore of a guide member 13. The piston 2 has a metering orifice 12 through which fluid passes into three inclined bores 11 leading to the conical closure surface 10. The pressure drop across the piston varies as the speed of the engine and when it exceeds the spring loading the valve element 10 is moved to close the port 4 until the engine speed falls to almost zero. The loading of the spring 14 is determined by the axial setting of the guide member 13 and for setting use is made of pressure indicating means connected to pressure connections 17, 18. Instead of the bores 11 in the piston 2 a by-pass passage having a fixed or adjustable restriction and connecting the two ends of the bore 3 may be made in the body 1.
