Title: Improved machine for making looped wire for use in sieves, floors or the like
IPC: B21F1/06
Filed: 1920-10-21
Abstract: 174,420. Booth, P. Oct. 21, 1920. Making metal fabrics; ; bending-formers. -In a machine for producing straight or zig-zag lengths of wire with loops at intervals for usa in making sieves, floors, &c., of the type in which wire from a spool on a rotating wheel is coiled at each revolution round a retractible pin, a series of pins are carried on a wheel which is operated to project and withdraw the pins. In the form shown, the wing, which is looped in succession round a series of pins S on a wheel R to form a looped wire as shown in Fig. 5. is led to the pins from a spool G on a bevel-wheel D over a guide roll and through a staggered series of guide-rolls Y so as to tension the wire. The bevel-wheel is rotated on ball bearings E by a pinion I carried by the main shaft J, which is driven by belt crear. The pin-wheel R is carried l1y a sleeve P which is revolubly mounted on a stationary shaft 112 and carries at its other end a star-wheel 0 with a similar nnmber of teeth rotated step by step by a roller Q on the wheel D and held in position by spring- pressed balls g engaging recesses h therein. The pin-wheel, Fig. 4, is provided with holes in which the pins may be moved and has a large groove R' which receives a series of blocks T, to each 'of which a pin is secured by a set-screw W. On .each set-screw is mounted a roller V which, ,during rotation of the wheel, runs in a circular .eccentric groove in a wheel U secured to the shaft M, so that the pins are forced out radially prior .to looping of the wire and are retracted after the looping takes place. In making a looped wire as shown in Fig. 5, the rotation is always in the same direction, but in the case in which alternate loops are on opposite sides of the wire, the direction of rotation of wheel D is reversed every revolution. This is effected by a tooth thereon engaging a projection on the belt-shifting rod d, which is held in position by a weighted lever c and stops a or b. In this case the pin-wheel is provided with two staggered rows of pins.

Title: Improvements in safety devices of motor-wound spring movements
IPC: G04C1/12
Filed: 1931-10-29
Abstract: 381,738. Spring mechanism. AKT.- GES. FœR SCHALTAPPARATE, 23, Gerbergasse, Berne, Switzerland. Oct. 29, 1931, No. 29989. Convention date, Nov. 5, 1930. [Class 10.] In a safety device for preventing overwinding of motor-wound clock movements, in particular for electric time switches, a coupling between the motor and the movement is thrown in and out by means of a friction coupling concentrically disposed in relation to, and operated by, a nut or other control element which moves along the arbor of the spring in accordance with the relative movement between the arbor and spring barrel. The spring movement shown, which is intended to operate a time switch, is wound by a motor (not shown) which rotates a wheel 28 which drives, through a helical spring clutch 29, a pinion 31 gearing with a wheel 3 on the arbor 4 of the spring 6. The arbor 4 is screwed, and carries a nut 8 on which is mounted a lever 9 having a turned-up end 91 which engages a stop 10 on the spring barrel, so that as the spring is wound the nut travels downwards and finally causes the face of the lever 9 to force down a ball bearing 12 which in turn presses a loose friction disc 11 into frictional engagement with the wheel 3. The disc 11 is thus turned, and by means of a forked extension 11<1> engaging a pin 13 on a lever 14 it moves the lever towards the left. An arm 16 secured to the same shaft 15 as the lever 14 is thus rocked and caused to arrest the movement of a star wheel 26 which is mounted loosely on the hub 27 of the wheel 28 and is provided with a pin 26<1> engaging the end of the spring 29, with which spring it normally turns. The spring 29 is thus prevented from turning and so ceases to tighten itself round the hub 27, thus allowing the wheel 28 to turn idly and arresting the winding movement. At the same time a tumbler switch 19 controlling the motor circuit is opened by means of the long arm of the lever 16, on which are pins 18<1>, 18<11> which engage a flexible extension 19<1> of the tumbler 19. When during unwinding the spring barrel has made a complete turn, the stop 10 engages the lever 9 and rotates it, causing the friction disc 11 to be raised and so allowing the lever 16 to be returned by a spring 17, thus releasing the star wheel 26 and closing the switch 19, so that rewinding commences.

Abstract: 878,213. Mowing machines ; hedge-cutters. FREEBORN, J. E., CHAPMAN, R. H., and MARR, W. F. Sept. 27, 1957 [Oct. 3, 1956], No. 30159/56. Classes 6(2) and 6(3). A mowing machine has two knife-bars reciprocated in opposite directions and forming a closed oscillatory system with the driving means and with a resilient device connected to the two knife-bars to store the maximum kinetic energy generated during reciprocation. The mower is mounted between the front and rear wheels of a tractor 10 and is driven from the lateral power take-off 11 through an eccentric 12 and connecting rod 13. The rod 13 reciprocates a shaft 14 longitudinally, the shaft being mounted in bearings 15, 16 and carrying a member 18 pivoted to a link 19. The link is coupled to a pair of parallel tubes 24, 25 so that its reciprocation twists the tubes about their axes, the tubes being secured at their lower ends both to internal torsion rods 30, 31 (which are anchored at their top ends) and to an arrangement including a link 34 symmetrically disposed relatively to the ink 19, whereby the link 34 receives the drive rom the shaft 14, via the link 19 and the orsion tubes. The link 34 is connected to two bell-cranks 36, 37 by a rod 35, each bellcrank being connected to one of the superimposed knife-bars 46, 47. The knife-bars are not identical, the upper bar having squarecut teeth 54 and the lower having triangular teeth 53, both bars being reinforced by riveting to flat bars such as 52. A mower-bar 48 forms a bed-plate on which the knife-bars rest, the mower-bar having forward portions 55 which carry pointed guards or fingers 56 embracing the knife-bar teeth but not serving any cutting function. The outer ends of the knife-bars are attached to levers 57, 58 pivoted at 59 on the mower-bar structure 48 and connected to a torsion-bar and tube 65, 66 so that the knifebars are maintined in constant tension by the torsion devices 65, 66 and 24, 25, the tension being Adjustable by rotation of the pivot 59 which is eccentric. The frame 28 which carries the tubes 24, 25 is pivoted to lugs 29 on a mounting plate 17 on the tractor, the pivotaxis being co-incident with a pivot between the link 19 and the member 18, so that the frame may be inclined at any angle without interrupting the drive. The mower-bar 48 is similarly pivoted to the lower end of the frame 28, whereby the cutters may be inclined at any angle or even elevated to the upper position in Fig. 16, for cutting hedges, an adjustable stay 49 being provided between the frame 28 and plate 17. Specifications 878,212 and 878,214 are referred to.

A method of finishing calendered sheet synthetic plastics material, e.g. sheet P.V.C., comprises supporting the sheet on an endless belt conveyer and passing it through a heating oven in which it is sufficiently heat softened to relieve any residual stresses therein. The stress relieved sheet, still on the conveyer, is then passed through a low pressure nip, around a surface modifying or rectifying drum, and on to a shock cooling drum, after which it is removed from the conveyer and further cooled and finally subdivided. The surface modifying or rectifying drum serves either to smooth out surface imperfections introduced during the stress relieving or to emboss the sheet with a required pattern. The conveyer may also be patterned, e.g. woven metal wire or cloth, so that the other side of the sheet is also embossed. A sheet produced by the above material is suitable as flooring.
