IPC: B65C11/04
Filed: 1919-01-02
Abstract: 141,110. Onderdonk, L. Jan. 2, 1919. Damping-machines. - In a machine for affixing postage stamps &c., a reservoir 11 for the damping-liquid is pivoted at 22 beneath the stamp-roll receptacle 8, and is secured by a keylock 53, Fig. 9. Liquid is ejected from the reservoir on to the end stamp of the strip, or on to the surface to be stamped, through a nozzle 47, an oscillating valve 35 being interposed to deliver a measured quantity of liquid to the nozzle at each operation. The valve is rocked by an elbow lever 39, Fig. 2, operated by a pin projecting from the stamp-affixing presser 74 to communicate alternately with the reservoir and with the nozzle. When the valve is in the latter position the liquid is forced from it by air supplied through a tube 26 from a compression chamber formed in the plunger 65. An inlet air-valve 71 is provided at the top of the plunger and an outlet 73 formed in the stem 61 of the plunger relieves the pressure before it becomes excessive. According to a modification, the liquid is ejected from the valve 35 by a plunger 159, Fig. 9, instead of by compressed air. The plunger engages in the valve by a screw-thread 160, and when it is rotated by a pinion 161 it first turns the valve through an angle limited by stops 158 to effect the necessary communication and then moves longitudinally in the valve to eject the liquid or to return to its normal position.

Title: Improvements relating to vehicles having steerable members
IPC: B62D12/00
Filed: 1955-01-05
Abstract: 764,513. Steering vehicles. GENERAL MOTORS CORPORATION. Jan. 5, 1955 [Feb. 2, 1954], No. 286/55. Class 79(5). [Also in Group XXI] The front wheels and wheel mounting of an earth scraper can be steered through 180 degrees about a substantially vertical axis by means of two fluid actuated jacks, each jack being connected at one end to the scraper body and at the other end to the wheel mounting, the connections of the jacks with the scraper body being closer together and nearer to the substantially vertical axis than the connections of the jacks with wheel mounting. In the embodiment, the wheels 27 on an axle 28 are steerable about an upright axis 30 contained in a yoke of an earth scraper, Fig. 2. Projecting backwardly of the axle 28 is an arm 21 carrying a cross-head 22 with the hydraulic rams 31, 31<SP>1</SP> pivoted at each end. The other ends of the rams are connected to a plate 15 which is fixed with the yoke of the earth scraper so that extension of one ram and contraction of the other will rotate the axle 28 until the longitudinal axis of the contracting ram passes through the axis 30 whereafter, for both to be operative, both must be extended. To permit this a valve 35 is mounted on the crosshead 22 with two plungers 37, 37<SP>1</SP> of which for instance, 37 is actuated by cam surfaces 49a, 49b, mounted on the ram 31 which in the position when the ram passes from contraction to expansion, engage a roller 42 at the end of a bell crank lever 41 connected to the plunger 37 through a spring-loaded compression rod 43. The plungers 37, 37<SP>1</SP> work in a valve box 36, Fig. 4, and are waisted to form valves. Each ram 31, 31<SP>1</SP> is connected at its ends to unions 36d, 36e, and 36d<SP>1</SP> and 36e<SP>1</SP> respectively, of the valve box 36. Two ports 36b and one 36c in the valve box 36 admit or drain away fluid supplied by pump P from reservoir 51, Fig. 5, depending on the position of a reversing valve 53 by means of which steering is effected manually. In the position of valve 36 shown in Fig. 4 the ducts are such that unions 36d<SP>1</SP> and 36e are in communication with the port 36c, while unions 36d and 36e communicate with the left hand port 36b. If the pump P is connected to port 36c, ram 31 extends while ram 31<SP>1</SP> contracts, while the reverse is true when pump P is connected to ports 36b. On moving either of the plungers 37, 37<SP>1</SP> to the right, by means of the cam surfaces 49a, 49a<SP>1</SP>, the ducts are such that the unions 36d and 36d<SP>1</SP> each communicate with one of the ports 36b, and the unions 36e, 36e<SP>1</SP> communicate with port 36c. In this condition both rams 31, 31<SP>1</SP> extend or contract together. By this means the wheels 27 may be turned through 180 degrees. Specification 713,600 [Group XXI], is referred to.

Abstract: 988,760. Sinks. R. HANNING. Jan. 8, 1963, No. 864/63. Heading A4N. [Also in Divisions F1 and H2] In a switching arrangement for a garbage disposal unit having electric-motor drive, the electric motor circuit has two switches, one of which is a diaphragm switch 16 in a housing 18 actuated by a pressure or vacuum generator 9, Fig. 2, connected to the diaphragm switch by a conduit 12 having a port which is closed by a valve 6 when the sink plug 4 is in the partly raised position. To start the motor the sink water tap is turned on and an automatic valve closes a switch in the motor circuit and plug 4 is then slightly withdrawn to expose the water holes and to close valve 6 thus hermetically sealing pipe 12. A rubber pressure generator 9 is then squeezed expelling air through spring-closed valve 13. On release of generator 9, valve 13 is closed and the vacuum which is created in pipe 12 and diaphragm switch 16 closes contacts 17 to start the motor. Failure of the water supply or removal or closure of the plug 4 stops the motor either by directly breaking the electrical circuit or by air admission to pipe 12 thus causing the diaphragm switch 16 to open contacts 17. The pneumatic system may operate by pressure and an automatic time delay, e.g. a capillary orifice 11 or a valve may be associated with the generator 9. A suction cup 9a allows the pressure generator to be secured to a suitable surface.
