Title: Cutting machines
IPC: B21D43/11
Filed: 1971-05-03
Abstract: 1401621 Feeding sheet metal; shearing SVENSKA ROTOR MASKINER AB 3 May 1972 [3 May 1971] 12744/71 Heading B3W A machine for cutting superposed layers of sheet material to successively form elements for heat exchangers and for collecting the elements thus formed into a stack comprises a shearing machine, a gripper reciprocable between a sheet pick-up and a sheet-release position for feeding superposed sheets to and beyond the shear blades, a stationary clamp between the blades and the sheet-release position and means for adjusting in a step-by-step manner the sheet pick-up position so as to change successively the width of the elements consecutively severed from the layers of sheet material. As shown, a gripper device 48, including a pressure plate reciprocated by rams 54, is reciprocable by means of a piston and cylinder unit 26, 44, 46 mounted in a frame 24. A similar stationary gripper device 60 carries stops 70 for limiting the feed stroke of the movable gripper device 48. For shearing superposed corrugated metal sheets 76 to form successive pairs of plates of increasing width, the frame 24 is movable along fixed rails 22 to progressively move away from the shear 12 the position of the gripper device 48 in which it grips the sheets 76. A rack 28 secured to the underside of the cylinder 26 meshes with a pinion 30 rigid with a shaft 32 journalled in the shear frame at 34. One end of the shaft 32 carries a ratchet wheel 36 which engages a pallet 38 which prevents movement of the frame 24 during the feed stroke of the gripper device 48. At the end of the feed stroke a servomotor 40 is activated to swing the pallet 38, moving the rachet wheel 36 clockwise one tooth and thus the frame 24 to the right. The gripper device 48 when it next grips the sheets is thus further from the sheat and feeds a greater length of sheet through the shear. The pairs of plates are collected into a stack to suit sector-shaped compartments of a heat exchanger. The shear is pneumatically actuated or driven by an eccentric.

Abstract: 345,537. Haymaking. MARTIN'S CULTIVATOR CO., Ltd., MARTIN, W. E., and MILLS, F. W. J., Ryhall Road, Stamford, Lincolnshire. April 25, 1930, No. 12778. [Class 6 (iii).] A side-delivery hay-rake, swath-turner, or like machine of the type having a pair of flyers, one of which is driven, the said flyers carrying rakes, is fitted with means enabling either of the short shafts supporting the flyers to be raised or lowered and the two shafts maintained in alignment. To the lower end a of the usual arched bar carrying the flyers is fixed a casting having an upper socket b and a lower channel portion c. The socket b receives the end a which is clamped therein by an arcuate bush drawn against the end by the bolt e. The channel part c is formed with a slot of which the upper part y is wider than the lower part h. The short shaft j; carrying one flyer, passes through a bearing in a lug m forming part of a member secured to the part c of the casting by a bolt t, passing through a bush p in a lug l on the casting, and the slot h, and a second bolt x passing through a vertical part k of the member and through the wide slot g. The head of the bolt x is formed as a screw-threaded eye y through which is screwed a bolt 1 passing through slots i in the sides of the channel port c and provided with a lock nut 2. By turning the head of the bolt 1 the casting is rocked to alter the inclination of the shaft j; a pointer n on the part k shows the degree of such inclination. The casting may be vertically adjusted by slackening the bolt t. The other short shaft is similarly mounted. The driven shaft takes the driver through level gearing and the other one is provided with a collar close to the lug m.

Title: Improvements in production of articles from plastic compositions containing vinyl resins
IPC: B29C48/95
Filed: 1934-05-04
Abstract: Articles, such as flashlight parts, tooth-brush handles, &c composed at least partly of a vinyl resin composition are produced by making a "heat unstable" preformed body of vinyl resin and subjecting said preform to heat treatment alone to cause it to assume its final shape and to make it "heat stable."  The term "heat unstable" refers to the state in which the elastic forces in the body are not all released but are held by the rigidity of the material below its heat distortion point.  According to one example, the vinyl resin was prepared by conjointly polymerizing 80 per cent by weight of vinyl chloride with vinyl acetate in the presence of 1 per cent of dibenzoyl peroxide as a catalyst and acetone as a liquid medium, the reaction taking place at 30 DEG  C. 3 per cent of carnauba wax and 2 per cent of alkaline calcium stearate were then added as lubricant and stabilizer.  The composition was mixed at 125 DEG  C. and then extruded under 2500 pounds per sq. in. pressure through a circular die of 0,275 ins. diameter.  The extruded rod expands as it leaves the die and is chilled to form a rod of 0,3 ins. diameter.  Sections of the rod were placed in a brush handle mould of slightly less than 0,35 ins. diameter and heated to 125 DEG  C. for 10 mins.  The sections expanded and filled the mould.  In another example a hollow tube of 0,75 ins. external diameter was extruded from a similar composition.  The hot tube was then expanded by air pressure inside a cardboard tube of 1,5 ins. diameter and chilled in this state.  The expanded tube was placed over a pipe of 1,25 ins. external diameter and warmed to 110 DEG  C. for 10 mins.  The resin tube contracted and closely fitted the pipe.  The resins used are polymerized vinyl esters or mixtures thereof, and mixtures containing vinyl esters and vinyl benzene, preferably resins produced by the conjoint polymerization of vinyl halides with vinyl esters of lower fatty acids in the proportion of 70 per cent to 95 per cent by weight of vinyl halide.  Mineral or cellulosic fillers such as cotton flock, wood flour, talc, asbestos, &c., may be added and also pigments or dyes.  For extrusion purposes, lubricants such as waxes, halogenated diphenyl and halogenated naphthalenes may be added up to 10 per cent by weight.  The finished articles may be polished by dipping in solvents such as ketones, halogenated hydrocarbons, and esters, e.g. ethyl acetate. p  Various articles such as furniture parts, pipes, vases, glassware, cables, &c. can be made.

IPC: B64D17/38
Filed: 1918-08-21
Abstract: 131,450. Roe, A. V. Aug. 21, 1918. Straps and bands.-The connexion between an aviator's harness and the fuselage of a machine comprises essentially an extensible spring which. when stretched beyond its limit of elasticity, remains stretched, whereby in case of a sudden heavy load on the spring-such as one due to a bad landing-there is no recoil of the spring. The spring 1 is a coil formed preferably of mild steel of strip, round, square, or rectangular section. The ends are either twisted together as shown at 4, to form a loop 3 at each end, or the ends may be secured together by thin wire 18, Fig. 5, placed in notches cut in the ends. The loops 3 may be connected at one end by a shackle 13, Fig. 2, to a lug 15 secured to the frame 6, and at the other end by another shackle 11 to cords 8, adjustable by means of a screw 7 and nut, the screw being connected to the aviator's harness 5. In the form shown in Fig. 4, two weaker tension springs 19, made of spring steel, are employed, one on each side of the main spring 1 of limited elasticity, the ends of all the springs being pivoted to pairs of plates 20, 26. The pins 25 are adjustable in the holes 27, so as to adjust the tensions of the springs 19. Instead of the springs 19, tubular telescopic casings containing compression springs may be used. In the form shown in Fig. 5, only one additional tension spring 28 is used, one end of which is adjustably held to a U-shaped plate 30 by an adjustable screwed eye bolt 31, and the other to duplicate plates 29. In this arrangement, the spring 28 alone stretches under a light load. but when the parts are stretched to the positions indicated in dot-and-dash lines, that is when the pivots 12, 24, 22 and 21 are in alinement, the spring 1 also is extended, and, when stretched beyond its limit of elasticity, remains extended,

Abstract: 719,966. Tills. MOGLER, E., [trading as MOGLER, E. [Firm of] ]. May 30, 1952 [June 22, 1951], No. 13809/52. Class 116 [Also in Groups XXV and XXXVIII] A burglar-proof till has a locking mechanism set by levers which when the levers are appropriately positioned prevents the till from being opened fully and also causes an alarm to be sounded when an attempt is made to open the till. The till comprises a number of hand-operated levers 6 (of which only one is shown in the Figure) mounted beneath the drawer-handle 4. When one of the levers 6 is lifted the far end of a lever 8 also rises and causes a corresponding pivoted bar 12 which is normally tilted as shown under gravity to tilt in the opposite direction. Each pivoted bar has two bolts 13. 14 passing through it and attached to a further pivoted bar 11 so that either bolt may be pushed down flush with the upper surface of the bar 12 in which case the other bolt protrudes. With the lever 6 and the bolts 13, 14 arranged as shown, the bolt 13 slides past the catch 25 when the drawer 1 is opened, for example to the position shown. When, however, either the lever 6 is lifted thus lifting the end of the bar 12 having the protruding bolt 13 or the bolt 14 is pushed down flush with the bar 11 thus causing bolt 14 to protrude, the protruding bolt (either 13 or 14) engages with the catch 25 thus preventing the till from being opened. Also the catch 25 slides forwards as the drawer is pulled and moves a rod controlling a clockwork-driven alarm bell thus releasing the alarm. When the bolt 14 is protruding the lever 6 must be lifted to allow the drawer to open. The alarm bell may be wound by key or means may be provided for automatically winding the alarm when the till is opened.
