A lever shearing-machine comprises a work support on a bed along which slides a carriage having a fixed blade below the work and a hinged blade above the work, means mounted below the level of the support for actuating the hinged blade and traversing the carriage and means for deflecting the severed portion of the sheet out of the plane of the uncut sheet, the connection between the hinged blade and its actuating means passing through the gap thus formed. The carriage comprises a box-like casing 3 slidable along the bed of the machine and traversed by means of a sprocket 41 engaging a chain 42 which is fixed at its ends to the bed and passes around pulleys 43 and the sprocket 41. A motor at one end of the bed drives a shaft 6 on which is keyed a sprocket 8 moving with the carriage and in driving connection with a shaft 13 which carries a sprocket 14 and an adjustable eccentric sleeve having an eccentric pin 20. The traversing sprocket 41 is mounted on a shaft 17 having a splined clutch member 28 engageable with a sprocket 16 directly driven by a chain from the sprocket 14 for a rapid return of the carriage and engageable with a ratchet-wheel 27 operated by a double-armed lever 26 from the eccentric pin 20 for a step-by-step advance of the carriage. The other end of the lever 26 is connected by a link 33 to an arm 32 depending from a stud pivoted in the carriage and coupled by an adjustable link 35 to the rocking blade-carrying arm 36. The clutch 28 is operated by a pivotal yoke 45 on a stud 46 carrying pulleys 48 and a two-armed member 47 adapted to be operated by trip cams 49 at each end of the bed to put the clutch into neutral position and by a handlever 53 through an endless cable arranged as shown in Fig. 5. As part of a sheet is severed between the fixed blade 55 and the movable blade, it is deflected downwardly by a guide 56 on the carriage so as to clear the links connecting the lever 26 and blade carrier 36. In a modification, the cutting and traversing mechanisms are operated by an electric motor mounted on the carriage. Specification 612,900 is referred to.

Abstract: 1,216,853. Sawing. G. W. WYNN. 1 May, 1968 [1 May, 1967], No. 19974/67. Heading B5L. Location apparatus for setting a pair of parallel location planes for an elongate workpiece extending transversely of the planes is characterized by one of the planes 59 being defined by a face on one side, or a pair of faces on opposite sides of a space in which the workpiece is placed for cutting, the second plane being defined by a blade 60 arranged parallel to but spaced from the face or faces and displaceable on the second plane, the spacing of the planes being arranged to determine the spacing of saw-cuts to be made in preparing a jointing recess in the workpiece. The first plane is comprised by a wear-resistant surface 59 on a member 52 fixed with a member 51 to spaced bars 56. A third member 53 having a wear-resistant surface 59 is spring-urged towards the member 52 so as to guide a saw when cutting a workpiece located transversely to the members which are U-shaped and form a recess for receiving the workpiece. A fourth member 54 is adjustable along the bars 56 and pivotably carries the blade 60 which can be located in a previously-formed saw cut in the workpiece to locate the cut a predetermined distance from the member 52 and a second cut which is to be formed in the workpiece using member 52 as the guide. Projections 64, 66 assist in the setting of the members to the width of the recess to be cut in the workpiece. The clamping means for the fourth member may be arranged so that the members are moved relative to one another as they are clamped to slightly close the gap therebetween so that the recess cut produces a tight joint. In another embodiment, the recess is formed as an open-sided stop to enable a joint to be formed on the end of a workpiece.

Abstract: 886,400. Anchor-bolts. DOWTY MINING EQUIPMENT Ltd. Jan. 18, 1959 [June 23, 1958; Oct. 17, 1958; Nov. 14, 1958(3)], Nos. 20058/58, 33244/58, 36709/58, 36734/58 and 36735/58. Class 89(1).  An anchor bolt, e.g. for mine roofs, comprises a shank 1, Fig. 1, surrounded by a sleeve 2, and a head 3, e.g. of rubber, located between collars 5, 6 on the sleeve and stem for expansion by relative axial movement therebetween caused, e.g. by a nut 19 applied to the screwed end 15 of the stem. A bracket 8 is secured to the outer end of the sleeve and supports a lever 23, Fig. 3, the arms 24, 25 of which engage the trunnions 17, 18 on a block 16 engaged under nut 19. The end surfaces 29, 31 of the arms form cam surfaces bearing on the base 9 of the bracket 8, and pivoting of the lever from the position shown to a position in line with the shank and sleeve will allow the head 3 to return to its unexpanded condition so that the bolt can be pulled out of its bore-hole by the lever. Pegs 13, 14 extending from the sides of the bracket into grooves 34, 35 in the arms, ensure that a pull on the, lever is transmitted to the sleeve and not to the shank. After installation of the bolt, the shank and sleeve may be tensioned by driving a wedge 37 laterally between a plate 39 surrounding the mouth of the borehole, and a wedge 36 fixed beneath the bracket base 9. The edges 45 of the bracket are bent and formed with slots 46 to adjustably support an arm 49 by which, e.g. a board can be held under the face of the roof &c.

Abstract: 480,525. Type -- making machines. DEVEZE, F. July 20, 1936, No. 20078. Convention date, Aug. 6, 1935. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 20, 1937.] [Class 100 (iii)] Single-type composing and casting machines ; justifying type; galley-mechanism.-Relates to means for setting up tabular matter, especially on machines of the kind described in Specifications 10174/12 and 199,011, [both in Class 100 (iii)]. (1) In order to effect the independent justification of the several sections of each line, the rod, which, on the completion of each line, is moved towards the central rod of the units-counting mechanism, in order to measure the shortage of the line, is replaced by a carriage 229, Fig. 4, carrying as many rods 98 as there are justified sections in the line. The lengths of the rods are such that the free end of the first and longest rod is, before composition, located at a distance from the central rod of the counting-mechanism corresponding to the width of the first column, the end of the second rod at a distance corresponding to the width of the first two columns, and so on. The carriage is moved by hand or automatically along a guideway 230 to bring the rods successively into position. The carriage may be replaced by a barrel. (2) The head 226 Fig. 1, that transfers the lines to the galley is put out of action until all the sections of the line have been completed. The head is pivoted, and is held raised above the line during the movement of its actuating lever 227, which occurs on the completion of each section, by a lever 243, the left-hand end of which engages a mutilated toothed gear 232. The gear is rotated step-by-step by the lever 227, and, on the completion of the last section, a blank part of the gear allows the head 226 to remain in the lower position, so that the line is transferred.

Title: Improvements in and relating to ball tip writing instruments
Inventor: FEHLING HANS REINHARD
IPC: B43K7/02
Filed: 1952-08-26
Abstract: 723,425. Reservoir pens. BIRO SWAN, Ltd., [formerly BIRO PENS, Ltd.]. Aug. 26, 1952 [Aug. 28, 1951], No. 20223/51. Class 146 (3). The ink reservoir of a ball-point pen is initially closed, and to prevent the pressure above the ink meniscus falling substantially below atmospheric during the early part of the writing life of the reservoir, a gas-emissive medium is introduced into the reservoir above the ink meniscus. As shown in Fig. 1, a capillary tube reservoir 1 having a writing extremity 2 at one end and a closure plug 6 at the other, has the vent hole 8 in the plug 6 closed by a removable or frangible disc 9, and between the plug and the ink meniscus 5 there is a tube 10 having a small capillary bore in which there is a liquid 12. The liquid 12 has a boiling point between 20 and 35‹C. and may comprise trichlorofluoromethane, methylformate, or 1-4 pentadiene, and is such that gas will be emitted to maintain the pressure in the space above the ink meniscus 5 substantially at atmospheric pressure while some of the ink 4 is used up in the act of writing. The liquid 12 also may comprise carbon dioxide dissolved in water or some hydrocarbon oil. When the pen ceases to function, the disc 9 is pierced or removed so that air can enter the reservoir, and the pen will function in the normal manner. In a modification, the liquid 12 is in the vent 8, and the tube 10 dispensed with. The gasemissive liquid could be used in reservoirs of non- capillary size, where a piston or viscous plug rests on and follows the ink meniscus down the reservoir tube. In the form shown in Fig. 5, the gas-emissive liquid is held by a porous plug or sponge 15 which may be vented at 16 to facilitate entry of air when the disc 9a is pierced or torn off. In all cases the gas pressure should not be so high as to cause ink to seep from the gap between the ball and its housing. Specifications 573,747, 629,226, 652,359, 688,891, .695,621 and 695,861 are referred to.

Title: Circuit interrupter
IPC: H01H33/91
Filed: 1964-05-15
Abstract: 1,044,076. High voltage switches. S. & C. ELECTRIC CO. May 15, 1964 [July 10, 1963], No. 20290/64. Heading H2B. To reduce the operating stresses on the bellows 91, Fig. 9, providing a gas tight seal between the auxiliary contact operating rod 97 and an end terminal member of the circuit interrupter of Specification 966,110, a dash-pot arrangement cushions the final opening movement of the auxiliary moving contact or contacts. This dash-pot arrangement comprises a cylinder 153 concentric with a fixed pump cylinder 149 and an annular piston 151 fixed to a movable piston cylinder 147. When the auxiliary contacts are opened, the piston cylinder 147 moves to compress the gas in the cylinders 147, 149 to provide a gas blast for the contacts 130, 133 and the piston 151 moves freely in the space between the cylinders 149, 153 until it covers slots 157 in the cylinder 153, the movement of the moving contact assembly then being braked. In a modified arrangement, Fig. 10 (not shown), the slots are provided in the cylinder 149 so that the initial movement of the piston 151 augments the blast. Shock is further reduced by the provision of a resilient lost-motion connection between the main and auxiliary contact operating arms, Fig. 6. This connection is provided by a stainless steel spring 198 having one end wrapped around a pin 200 on the main contact operating arm 176. The spring is shaped to form a loop the ends of which co-operate with a pin 204 projecting from the auxiliary contact operating arm (not shown). A rigid link 208 with a slot 210 longer than the loop in the spring prevents the spring being stretched beyond its elastic limit.

Abstract: 948,816. Magnetic brakes. VECTRON ELECTRO-PHYSICS Ltd. June 9, 1960 [June 18, 1959], No. 20956/59. Heading H2A. [Also in Divisions F2 and G5] A reversible magnetic tape recorder has two spooling arrangements, either of which has a steel braking disc 115 which is seized by the polepieces 122, 123 of a double solenoid pivoted about the point 124, against the action of a spring 125. Should the power supply fail, a member 127, normally held away from an arm 129 by a solenoid 128, is urged by a spring 130, stronger than 125 to provide fail-safe braking. At a lower value of current in the solenoid, insufficient to overcome the spring 125, the polepieces, adjusted by a means 126 apply an eddy-current braking effect to that spool which is, at the time in trailing relationship. The disc also carries a ring of holes 116, forming photo-electric tachometric means 117, 118 to control the torque applied to the take-up spool by controlling a magnetic particle clutch 110 in inverse relation to the take-up rotation speed to maintain a constant tension in the tape as the diameter of taken-up tape varies. The photo-electric means in the feedspool means similarly regulates the current in the solenoid providing the eddy-current braking.
