Title: Improvements in or relating to circuit interrupters
IPC: H01H71/12
Filed: 1926-03-13
Abstract: 270,456. Davies, D. R., and Metropolitan-Vickers Electrical Co., Ltd. March 13, 1926. Automatic circuit-breakers; boxes and cases.- In circuit interrupters which are automatically opened on the blowing of a fuse, the switch and fuse are oil immersed, the fuse being connected between movable members biassed to move apart the movement of one of said members, by either tripping a detent or breaking a toggle, permitting the switch to open under the influence of a spring. The switch is mounted in a tank the interlocked cover of which carries the switch mechanism, and in the case of multi-pole or polyphase circuits the blowing of the fuse in any one phase effects the opening of all the poles and phases. As shown in Figs. 1 and 2, the movable contacts of the three phases are carried by insulating bars 34 pivotally connected to parallel links 30, 32 which move about centres 26, 28. The upper ends of the movable contacts carry pivotally at 50 movable members 48, 49 biassed by springs 52 to move apart and connected between points 54 by fuses 53. On the blowing of a fuse in any phase the left-hand member 48 is moved by the spring 52 with increasing mechanical advantage until it sharply engages the tail of a detent 56. The detents 56 are secured on a shaft 26 which, by its rotation, moves a latching projection 58 from a recess in the bell crank 60 on a shaft 62 which is connected by a link 64 to an extension by an arm 32, the switch being moved to the open. position by a spring 68. The switch is reclosed by an external handle 70 on the shaft 62 and a second handle 72 secured to a shaft 76 permits manual tripping by rotating a projection 78 engaging a detent 56. The handle 72 has an interlocking projection engaging a corresponding projection on the side of the tank 11, Fig. 2, so that the cover 13 can be raised and lowered only when the switch is in the " off " position. In a modification the switch is operated by a toggle linkage which is tripped by the blowing of a fuse in any phase.

Abstract: 1,253,553. Work-holders; vices. IMPERIAL KNIFE ASSOCIATED COMPANIES Inc. 10 Feb., 1969, No. 7067/69. Headings B3B and B3D. [Also in Divisions E1-E2] A portable pneumatically operable clamp for simultaneously gripping a series of elongated articles A, Fig. 1, in spaced parallel relation for finishing operations, e.g. buffing or polishing, comprises a pair of elongated clamping members 12, 14, Fig. 3, pivoted together by means 16 and each comprising a jaw 28, 30 and an operating portion 46, 48 respectively, means biasing the jaws 28, 30 to their open position, a tube 20 situated between the operating portions 46, 48, and means for selectively permitting entry of high pressure air into, retention of air in, and exhaustion of air from the tube, the arrangement being such that when the tube is inflated the jaws are urged together and when the tube is not inflated the jaws are urged apart by the biasing means. In the embodiment described, the members 12, 14 are pivotally connected by a series of hinges 50 and the jaws are biased to their open position by the ends 70 of coil springs. The jaws 28, 30 are provided with channels 36, 38 containing elastomeric pads 42, 44 for gripping the articles A, which may be articles of cutlery. The pads and channels may be removable. Alternatively the pads are of elastomeric material or metal contoured to receive the tang portions of knife blades. The tube 20 includes a hose 74 retained by straps 114 and is provided at one end with an inlet coupling 82, Fig. 1, by means of which it may be connected to a source R of air under pressure. In use of the clamp the articles A are placed between the jaws whilst these are open, the coupling 82 is then connected so that the tube 20 is inflated and the jaws closed. The coupling 82 is then disconnected and a valve operates to retain the air under pressure within the tube 20. The clamp is then placed on a finishing machine and trunnions 116 at the ends thereof are urged against stops on the machine as the exposed portions of the articles A are fed between a pair of counter-rotating buffing or polishing rollers. The clamp may be reciprocated axially during the buffing or polishing. When the operation is completed the clamp is removed from the machine and a valve is operated which permits release of the air under pressure and hence allows the jaws to open under the action of the springs.

Pistons, piston packing.-the piston of a Diesel or other internalcombustion engine is packed by a flexible ring, preferably of bronze, of the split cup leather type, the packing-ring groove being arranged at a distance at least equal to 1-10 the diameter of the piston from the piston-head in order that the packing may be protected from the flame. In order to permit access of the fluid to the packing, the piston head is formed of reduced diameter or with grooves or passages leading to the packing-ring groove. The packing may lie wholly in a rectangular groove as shown in Fig. 13, the distance of the top of the flange A<1> from the top of the groove being varied according to the fluid-pressure which it is desired to admit. A single keeper ring Z may be employed, or two keeper rings may be used, either placed both above the packing-ring or one above and one below. The keeper rings are shaped to permit access of the fluid to the packing-ring flange. Fig. 13 shows the piston formed with recesses D for permitting access of the fluid to the packing-ring groove. In other arrangements, the flange A<1> of the packing-ring lies in a part of the piston of reduced diameter, as shown in Fig. 28, the reduction being either cylindrical or conical. The fluid may be admitted to the packing-ring groove by a cylindrical or conical reduction of the piston head, or by grooves, or by passages B<2>, which may be regulated by screws b or otherwise. In other arrangements, the piston is formed with a detachable head B<x>, Fig. 21, the packing-ring groove being formed wholly in the body B, or partly in the body and partly in the head, or wholly in the head, as shown. Fig. 32 shows a piston provided with a supplementary packing-ring G, which may be an ordinary split ring, or of cup-leather type as shown, and may be formed with grooves or perforations g to permit access of the fluid to the lower ring A. The packing-ring may have a cylindrical flange A<1> or a flaring flange or a lip making line contact with the cylinder. The joint, in the packing-ring may be covered by a tongue E, Fig. 36, which may be riveted to one end, as shown, or may be slidably attached to both ends, or may be loose and provided with means for preventing' displacement, such as a projection entering the joint. In order to reduce wear, the ends of the packing-ring are thickened e.g. by plates H riveted to the ends. The tongue may be formed with a lip making line contact with the cylinder. The keeper ring may be formed in sections, as shown in Fig. 23, the sections being hinged together by a pin Z' and the open ends formed to overlap and secured by a pin Z<6>. The packing-ring may be made in accordance with Specifications 8571/15, 16120/15. 17221/15, 17222/15, 123,328 [Class 83 (ii), Metal articles &c.], 123,329, 123,330, 123,331, 123,333, and 123,334.

Filed: 1931-03-11
Abstract: 374,919. Driving sound-and-picture films. UNIVERSUM-FILM AKT.-GES., 6, Kochstrasse, Berlin. March 11, 1931, No. 7529. Convention date, April 7, 1930. [Class 40 (ii).] For regulating the speed at which sound- and-picture films are driven during the examination thereof, a combined constant-speed and variable-speed drive is provided, the normal film speed being obtained by switching in the constant-speed drive while other speeds, which may be low for picture checking or high for rewinding the film, are obtained by control of the variable-speed drive. In the driving means shown, a direct-current motor 2 and a synchronous alternating-current motor 3 are mounted on a common drive shaft 1. The motor 2 is shunt wound, a variable resistance 7 being included in the series winding 5 and a variable resistance 9 in the shunt winding 6. On moving a slide 8 from right to left, the motor 2 is gradually speeded up until the normal speed is reached when a projection 13 closes a spring-controlled contact 12 to switch in the constant-speed motor 3. On further movement to the left, the slide cuts out the motor 3 and speeds up the motor 2. Movement of the slide to the extreme left against the action of a spring 15 causes the resistance 9 to weaken the excitation of the field produced by the shunt winding 6 and the maximum speed of the motor 2 is thereby attained. Specification 344,078, [Group XXXVII], is referred to.

Abstract: 785,183. Feeding sheets. BALJAK CORPORATION. March 13, 1956 [April 15, 1955], No. 7792/56. Class 100(1) Sheets B, such as box blanks, stacked on edge in a magazine 12, are separated by suction grippers 16 and placed horizontally on folding dies 49 to be operated on by vertically-reciprocating plungers. As shown, there are two stacks 14 supported on rods 15, and the blanks B in each stack are withdrawn through gates 13 by three suction cups 16 mounted on a common transverse bar 17, the ends of which are secured'to a pair or double-armed gripper arms 18. Each arm 18 is pivoted at 21 on a first bell-crank lever 20 pivoted at 31. and the outer end of the arm is provided with guidways 24 engaging a pivot 25. This pivot 25 is mounted on a second bell-crank lever 26 pivoted at 27 to the framework 11 of the machine. A rod 28 connects the two bell-crank levers, so that oscillation of the bell-crank 20 about its axis 31 results in oscillation of the second bell-crank 26 about'the axis 27, and the pivot 25 controls the movement of the arm 18 by sliding therein along the guideways 24. The first bell-crank 20 is connected at 32 to a rocking arm 34 by a connecting-rod 33, this arm being rocked about a central pivot 35 by a rod 37 connected to a crank 38 on the drive shaft 39 of the machine. The crank 38 also operates the reciprocating plungers. As shown in Fig. 4, the complex motion of the gripper arm 18 results in the sucker bar 17 following a path 60, and the points on the path marked 1 to 6 represent the positions of the bar 17 equivalent to six equally-spaced points on the semi-circular path of the crank 38. The removal of a blank B from the magazine takes place at an extremely slow rate; it is swung to travel edge first, reaching peak velocity shortly after position 4; and then decelerates gradually to position 6 where it is deposited slowly on the folding die 49. U.S.A. Specifications 2,624,249 and 2.655,843 are referred to.
