IPC: B21D28/26
Filed: 1917-02-26
Abstract: 113,646. Marks, E. C. R., (Steel Utilities Inc.). Feb. 26, 1917. Punching.-In a punching-machine Punching.-In a punching-machine, F I G.10 the beam &c. is advanced by a roller table against a sliding stop on a bar with projections at distances of a foot with projections at distances of a foot or other denomination and brought to rest, when the desired distance has been covered, by one of the projections being engaged by a member which is adjustable also for smaller denominations. The stop 15 is on a rack bar 16 having projections 20 one foot apart, and as the beam x is advanced by rollers 1, the rack 16 rotates the gears 101, 103, 104, 107, 109, 110, Fig. 7. A number of electrical contacts 128, 119 are arranged in fixed plates 150 opposite disks 111, 112 carried by the gears 110, 104, the gearing being such that small insulated segmental plates 123 on the disks 111, 112 pass one contact for every foot and every ten feet respectively that the rack 16 &c. moves, The plates 123 are electrically connected and the contacts 128, 119 are arranged in a gap in the electric circuit for the solenoid Fig. 3, so that, when both plates simultaneously engage corresponding contacts which have been set according to the desired number of feet the beam is required to move, current passes and the solenoid 33 causes the pin 31 to be advanced into the path of the corresponding projection 20. To get the desired number of inches and sixteenths of travel, the guide 28 carrying the pin 31 is moved along a bar 23, by a cam 29 and a groove 36 engaged by a hook 38, before the projection 20 engages the pin. The cam is rotated through a slipping clutch 54. Fig. 2, from a motor 64. the rotation being limited by the setting of the desired pin in each of the series 67, 86 to engage slots 66, 85 of the required length in the cam 29 and in a drum 81 respectively. The pins 67 are carried by the drum 81 and the pins 86 by a fixed drum 24. The pins 67, 86, and contacts 128. 119 are preferably actuated as described in Specification 12139/15 by solenoids under the control of a perforated or like strip 140, Fig. 10, only one of each of the sets of contacts 141, 142 being shown. Preferably two sets of the apparatus shown in Fig. 3 arranged with oppositely acting cams as shown in Fig. 1 are employed, one acting while the other is returned to zero by the motor 64 which is reversed by a multiple double-throw switch s operated from the punch mechanism, or otherwise, to connect the four middle contacts with the upper and lower contacts alternately. The switch s also diverts the current from one of the solenoids 33 to the other and from the solenoids actuating the pins 67, 86 of one cam controller to the other. The current for the motor 64 cannot flow until the solenoid-actuated switch d or e is closed by the closing of the switch i or h when the correct pin 31 is projected.

Title: Improvements relating to carburettors for internal combustion engines
IPC: F02M17/04
Filed: 1939-01-30
Abstract: 524,419. Spray carburetters. PALLAS APPARATE GES. Jan. 30, 1939, No. 3160. Convention date, Jan. 29, 1938. [Class 7 (iii)] A spray carburetter comprises means for effecting a supplementary regulation of the fuel-air ratio in accordance with altitude changes an auxiliary chamber for supplying a rich mixture to a main mixing chamber, the inlet to or outlet from the auxiliary chamber, or both, being controlled by a regulating member which is adjusted conjointly with a main throttle or set automatically by a pressureresponsive device beyond the main throttle, and a preliminary chamber having an air inlet valve controlled by a barometric device to produce therein a pressure which is a function of the atmospheric pressure, the preliminary chamber supplying air to the auxiliary mixing chamber. A chamber 20 surrounding the air-inlet 1 communicates by a passage 19 with a closed chamber 18 containing an aneroid box 17 which controls a conical valve 16 admitting air to the preliminary chamber 13. A reduction in atmospheric pressure closes the valve 16 to shield the chamber 13 from the full effect of the reduction. The chamber 13 communicates openly with the top of the float chamber or equivalent fuel supply device and through a valve 7 with the auxiliary mixing chamber 4 which is open to the main mixing chamber 3 through a valve 8 connected to the valve 7. A fork 10 links the valves 7, 8 to the main throttle 2. Fuel is drawn into the chamber 4 through a nozzle 11, the' pressure in the chamber 4 being less than that in the float chamber and chamber 13 through its exposure to the main mixing chamber. The suction on the nozzle 11 does not fall as the pressure in the mixing chamber 3 rises with the opening of the throttle 2 since the valve 8 opens correspondingly and communication between the chamber 3 and 4 is freer. As shown in Fig. 4, a diaphragm regulator replaces the float chamber and the valves 7, 8 are actuated by an aneroid box 25 exposed to the mixing chamber 3 instead of by direct connection with the throttle valve 2. In either case, if the carburetter is used with a supercharger, the valve 16 is made of double-conical form to operate in the opposite sense while the supercharger is maintaining a constant input but to operate as described above if the carburetter is working at a height greater than that for which the supercharger can compensate.
