Title: Improvements in sealing apparatus for jars, cans and the like
IPC: B65B7/28
Filed: 1931-11-16
Abstract: 383,744. Canning food. WHITE CAP CO., 1369, North Branch Street, Chicago, U.S.A. Nov. 16, 1931, No. 31720. Convention date, Dec. 20, 1930. [Class 49.] Apparatus for sealing jars, cans, &c. containing food comprises means for feeding continuously jars &c. through a steam &c. chest and means for applying and sealing a closure on the jar &c. during its continuous movement through the steam &c. atmosphere. As shown the closures are fed from a rotating table 75 having stationary guides 77, 78, adjustable for varying closure sizes, between adjustable shoot rails 15, which project into the steam chest 10 over the path of the jars &c. carried by a conveyer 11. The lowermost cap C is retained by a weighted detent 56 held closed by the thrust of a spring-pressed bar 62 on the upturned nose of the detent. This bar is periodically raised by a tappet 66 rocked by a cam 67 through a bell crank 68 and rod 69, so that the rim of an advancing jar may engage the depending cap and withdraw it from the shoot During this withdrawal the succeeding closure is held by a second detent 57 carried on an adjustable block 70 mounted on a rocker 71 which is held fast by a spring-pressed plunger 74. When the tappet 66 rocks in an anticlockwise direction the arm 71a is engaged thereby, the detent 57 is raised and the cap slides down against the nose of the now depressed detent 56. The jar, with the cap loosely attached, now passes on to the sealing mechanism, Fig. 5, which comprises an endless, rigid-link belt 84 with flat outer faces moving synchronously with the conveyer 11 and carried on two pairs of sprockets 85, 86, journalled in the vertically adjustable bracket 25. The lefthand sprocket shaft 96 is resiliently mounted on a rod 98 vertically reciprocated by a lever 100, pivoted at 101, and a cam. This reciprocating end of the conveyer is slightly elevated when the jar, with the cap loosely attached, arrives beneath it and its downward movement exerts pressure, transmitted through springs 95, to hermetically seal the jar, which pressure is maintained while the jar is beneath the belt. The belt frame 88 is longitudinally adjustable. The steam distributer comprises adjustable pipes 24 and a horseshoe-shaped header 110. Baffles promote concentration of heat near the lower end of the shoot 15, and a waterspray 108 promotes cooling and consequently improved sealing while the closure is under pressure from the belt. The receptacle guidebars 41 are adjustable for varying widths of receptacles.

Title: Variable displacement pump
Inventor: PUNYEAR DAVID BURFORD
IPC: F04B1/32
Filed: 1963-08-14
Abstract: 980,605. Reciprocating pumps. BENDIX CORPORATION. Aug. 14, 1963, No. 32117/63. Heading F1A. [Also in Division G3]  The angle of the swashplate 16 of a rotating cylinder reciprocating pump 10 is varied in accordance with the flow and pressure in the outlet 26 of the pump. A flow responsive valve 32 is subjected at opposite ends to the pressures upstream and downstream of an orifice 28 in the outlet 26, and a pressure responsive valve 36 is subjected to the pressure in the outlet 26. Both valves are loaded by springs 68 to set the required flow and maximum pressure. While the outlet pressure is below the predetermined maximum, bands 64, 66 on valve 36 close a conduit 56, connected to a swashplate actuator 18, from the outlet 26 and connect this conduit to a conduit 54. While the flow is at the predetermined value, the conduit 54 is closed by bands 58, 60 but is connected to the outlet 26 or a drain line 52 when the valve 32 is moved due to a rise or fall in the flow respectively thereby admitting or exhausting fluid to the piston 18 to decrease or increase the pump displacement. When the pressure rises above the predetermined value, the valve 36 moves to close the connection between the conduits 54, 56 and connect conduit 56 to the outlet 26 to decrease pump displacement. The pressure control thereby overrides the flow control. The pump may be constructed as described in Specification 866,661.

Filed: 1930-10-27
Abstract: 363,459. Stop motions for yarn winding machines. HIGGINSON, J. and ARUNDEL, COULTHARD, & CO., Ltd., Sovereign Works, Stockport. Oct. 27, 1930, No. 32179. [Class 120 (ii).] Yarn-winding machines, of the drum type in which each tube or core upon which winding takes place is mounted on a mandrel carried by a cradle adapted to be lifted to stop the winding when an end breaks, comprises a drop wire b normally supported by the yarn c out of the path of a reciprocating rod d, the wire forming part of a pivoted detector a adapted to be displaced by the rod d when breakage of the yarn causes the wire to drop ; the displacement frees a hook g on the detector from a catch h on a weighted lever i which is pivoted at j and is formed with an arm k adapted to engage a depending arm m on a cradle pivoted at o to raise the cradle when the lever falls, the lifting of the cradle freeing the core p from its driving drum q. A dashpot s secured to the lever at u and having its piston t connected to the cradle, cushions the movements of these parts, the arrangement ensuring a gradual speeding up of the core p when the cradle is lowered. When the lever i is re-set, the catch h is positively engaged with the hook g by engagement with an arm 7 on the detector a. The rod d may be linked to the cradle by an adjustable rod w so that a raising of the cradle to a predetermined extent lifts the rod d into contact with the drop wire b and causes the release of the lever i to stop the winding, the yarn being severed by the pull of the cone after it has been nipped between bars 6 by a pivoted arm 4 secured to the detector a.

Abstract: 377,065. Fuel-injection pumps. L'ORANGE, P., 91, Robert Boschstrasse, Stuttgart, Germany. Nov. 20, 1931, No. 32204. Convention date, Nov. 21, 1930. [Class 102 (i).] In a fuel-injection pump of the type in which the plunger b, Fig. 1, is rotated by the governor by means of a lever k in order to vary the timing of the termination of injection, lost movement between the plunger and the governor transmitting-mechanism -is avoided by subjecting the plunger to a turning movement opposed'to the action of the governor. The inlet to the pump chamber takes place through a passage in the plunger controlled by a valve c and the injection is terminated when a passage g in the plunger passes the inclined edge h of a recess i in the cylinder. The passage g may be made tangential in order that the fluid flow may exert a turning moment on the plunger, or, alternatively, a torsion spring may be arranged between the plunger and the operating tappet o. Where the levers k<1> .. k<4>, Fig. 6, of several pumps are simultaneously operated, the turning moment preferably moves the plungers in the direction of light load and the governor rod n in the direction of full load, so that, if one plunger seizes, movement of the other plungers to light load position is not impeded.
