Abstract: 689,883. Resilient and slip couplings. INTERNATIONAL HARVESTER CO. Aug. 22, 1951 [Nov. 24, 1950], No. 19785/51. Class 80 (ii). [Also in Group XVII] A pick-up baler for hay or the like of the kind in which the baling mechanism includes an inertia flywheel to which drive is transmitted from a tractor through a transmission shaft and universal coupling means, has yieldable friction coupling means interposed between the said flywheel and an input drive connection .from the tractor whereby variations between power plant speed and the inertia flywheel speed may be compensated by slipping of the yieldable friction coupling means. Yieldable shock-absorbing means are interposed between said flywheel and an output drive shaft connected to the bating mechanism whereby stresses due to large reciprocating masses may be cushioned and relieved. Drive from a power take off shaft 14 of a tractor 10 is transmitted to the baling meehanism of a towed pick-up baler 16 through a universal coupling 29, telescopic transmission shaft 28, universal coupling 32 and yieldable friction coupling means 34 to an inertia flywheel 33 of the baling mechanism. The friction coupling means comprises, Fig. 2, a disc 38 secured to a knuckle part 35 of the universal coupling 32 and pressed, by a spring-loaded coupling pressure plate 42 carried by the flywheel 33, against a shoulder face 48 of the flywheel. The flywheel drives, through yieldable shock-absorbing means, a shaft 66 driving through a shaft 73 and bevel gears 76, 27 a crank shaft 26 which by means of a crank arm 24 and pitman 23 reciprocates a bale-compressing plunger 22 in the baling chamber. The yieldable shockabsorbing means comprise Figs. 2, 4, compression springs 56, 57 disposed between projections 52, 53 on the flywheel 33 and lugs 54, 55 on a driving plate 51. The plate 51 is journaled on a hub 49 of the flywheel and is secured by a shear pin 60 to a driven plate 58 welded to a sleeve 50 splined onto the shaft 66.

Title: Improvements in or relating to electro-magnetic contactors
IPC: H01H51/12
Filed: 1938-07-05
Abstract: 516,696. Electromagnetic switches. STANDARD TELEPHONES & CABLES, Ltd., and RUSSELL, W. F. July 5, 1938, No. 19900. [Class 38 (v)] The contact 35 of a contactor is moved into the "on" or "off" position by the energization of a magnet 5 or 6 and is held latched in the "on" position. In the construction shown in Fig. 1, the arm 12 carrying the contact 35 is latched in both the "on" and "off" positions by latches 22, 23. Energization of the magnet 5 attracts the common armature 9 and lowers a rod 14 which carries springs 34' bearing on either side of the arm 12. The copper spring is thereby strained until one of two collars 18, 20 on the rod engages a cam surface on one of the latches and presses it out of engagement with the arm 12 whereupon the arm 12 snaps downwards into contact and is held latched by the other latch. A similar action occurs when the magnet 6 is energized to open the switch. Subsidiary contacts 33, 34 operated by the movements of the latches serve to open the circuit of the magnet 5 or 6 immediately it has acted. In a modification, Fig. 3, the magnets 5, 6, have armatures 9a, 9b. Energization of magnet 6 attracts armature 9a, and moves downwards a rod 14 so as to move a latch 45 and break a toggle 43, 44, holding the contact-carrying member 12 in the closed position. A spring 39 thereupon moves the member 12 into the open position and changes over the auxiliary contacts 33, 34. The switch is moved back into its original position by energization of the magnet 5 and attraction of armature 9b.

Title: Improvements relating to strapping machines
IPC: B65B13/34
Filed: 1939-07-06
Abstract: 531,539. Sealing; wire-strainers. WILLCOX, T. W. J., and GERRARD INDUSTRIES, Ltd. July 6, 1939, No. 20156/38. [Class 146 (ii)] [Also in Group I] A machine for securing bale-ties by deforming a sleeve embracing the overlapped ends, comprises a tool mounted on a base for movement longitudinally of the strap, the tool including upper forming means which move down to meet a pair of jaws. The base 1 of the machine is bevelled at the front to facilitate insertion of the tie and also at the ends to prevent it from being bent at a sharp angle ; a step is formed on the base to provide a stop. The tie is placed beneath a tensioning-wheel 4, round the bale, under a positioning hook 18 and the free end passes beneath the other end under the wheel 4. The wheel is eccentrically mounted, and is caused to grip the ends of the tie between itself and a roughened plate 12 by releasing a lever 7 from engagement by a spring-pressed stud, when a spring rocks the shaft. The wheel is formed with two sets of oppositely-inclined teeth which converge towards the centre of the circumference so as to provide for centring the tie. The wheel is rotated to tension the tie by pawl-andratchet mechanism actuated by a lever 9. The deforming-tool is mounted between plates 25, 26 pivoted on a stud, the position of which relatively to the base is adjustable to enable ties of different widths to be secured. When the tool is swung over to operative position, a lever 41 (not shown) pivoted thereto rocks a bellcrank lever 45, one arm of which forms a cutter 14 co-operating with block 15. The tool comprises a pair of jaws 22, 23 having slotted operating-faces to form fingers which co-operate with cutting-surfaces 47, 48 formed on a block. The jaws are pivoted in the side plate 25, 26, and to operating-handles 32, 34 which are pivoted to a common axis slidable in slots in the side plates. Rocking of the handles 32, 34 causes the jaws to be depressed and to swing inwards to fold under the sides of a channel-shaped member placed over the overlapped ends of the tie. The pivots of the handles 32, 34 slide in slots in plates surporting the cutting-block, the cutting- surfaces of which are so shaped that they do not contact with the tie when to tool is moved to operative position. The final movement of the jaws presses the tie and sheath against the cutting-surfaces and deforms the cut-out sections downwardly. A lever pivoted to the side plate 26 has a projection which engages with the baseplate or the tie when the tool is moved to operative position, and is thereby rocked to move its upper end out of the path of the end of the axis of the levers 32, 34. One of the levers 32, 34 may be dispensed with.

Abstract: 202,098. Krause, A. C. June 6, 1922. Factory and like time-recorders, autographic; aligning and locking type-wheels; driving typewheels from clock. - Apparatus of the autograph type, in which a strip of paper is passed beneath an aperture in the casing, the aperture being normally closed by a shutter 47 held locked until a time-record has been printed and the paper moved so that the printed record coincides with the aperture the paper passing from a spool 9, under the record printing-wheels 7, and over a table 12 beneath the aperture to the spool 10, has a manually-operated rocking lever 20 pivotally connected to a plate 53 which operates the paperfeeding mechanism, to a cam-ber 21 which operates a hammer 11 to effect the printing of the time-record and the release of the shutter 47, and to a cam-bar 37 which operates a device for bring- ing the figures on the minute-wheel into the correct position for printing, the cam-bars coacting with fixed members on the casing to produce the desired motion. The plate 53 carries a lug 54 which moves a wheel 55 on the shaft of the paper carrying spool 10, a stop 56 on the arm 21 engaging the wheel 55 and limiting the movement. On the return stroke a pin 57 rides over a cam-plate 58 and lifts the plate 53 free of the wheel 55, a pin 61 positively moving the shutter 47 to the clcsed position. A pawl 59 prevents backward rotation of the wheel 55. A pin 41 on the cambar 37 engages a trip lever 33 resiliently pivoted to the arm 32 of a lever pivoted at 31 and carrying a finder 30, that engages between teeth 29 of a wheel on the spindle of the minute printing- wheel and brings the figures to the correct position, the minute printing-wheel being resiliently connected to the clock spindle. After the printing has taken place the cam-bar 37 is depressed by its cam 43 engaging a fixed pin 44, so that the pin 41 releases the trip lever 33. The cam-bar 21 engages, by means of a hook 25. a pin 23 on a lever carrying the hammer 11. The cam-surface 26, coacting with a fixed pin 27, lifts the cam-bar 21 and releases the hammer after it has been drawn back, so that under spring action it strikes the paper against the record printing-wheels, an inked ribbon being interposed. The pin 52 on the cam-bar 21 then engages a shoulder on the latch 50, pivoted at 44, and releases the shutter 47 which is opened by a spring, or positively by a pin on the plate 53.

Abstract: 588,977. Addressing and like machines. ADREMA, Ltd., and SANDERSON, T. E. F. Oct. 23, 1944, No. 20493. [Class 100 (ii)] In addressing, listing and like printing- machines in which printing plates 1 are fed, from a stack B along a track to a printing position A and, after printing, are fed in the same direction to a receiver 2, a device is provided co-operating with and functioning as part of the feed-mechanism to interrupt automatically the continuity of the train of plates whereby a gap is provided for exposure of a numberprinting device 3 situated in the path of the printing-plates and adjacent the printing position. As shown, the plates are fed from A to the receiver 2 by a pawl 7 on the end of a slidable rod 6, actuated from a feed-shuttle 8 so as to travel faster than the shuttle whereby the plate being delivered moves faster than those behind it, thus providing a gap between the leading edge A<1> of the plate, in printing position and the trailing edge D<1> of the plate, in front of it. The additional movement is provided by a pinion 9 in the shuttle engaging a stationary rack 10 and a rack 11 on the rod 6. To enable the pawl 7 to engage the trailing edges of the plates, the shuttle 8 is foreshortened at the leading edge 8a to provide a gap 12 between a plate 1 in viewing position C and'that at A, a pawl-rod 13 projecting from the shuttle feeding the plate from C to A. The ratio of the rack bars may be varied by using extra gears.

Title: Improvements relating to the sealing of cut edges of textile fabrics
IPC: D06M23/18
Filed: 1949-08-08
Abstract: 671,418. Treating edges of fabrics. BRITISH KAUMAGRAPH TRANSFERS, Ltd. (Kaumagraph Co.). Aug. 8, 1949, No. 20533/49. Class 42 (i). The cut edges of textile fabrics are sealed by associating an assembly of pieces of cut fabric with their cut edges in register, compressing the assembly from both sides along the lines of the cut edges and, while maintaining the state of compression, applying a fibre bonding treating agent in liquid form to the cut edges only of the assembled pieces and thereby promoting a bonding action between the cut fibres at the edges and the adjacent uncut threads of the fabric. As shown, a pile of fabric pieces 10, cut to the desired shape, are assembled with edges in register between rigid sheets 12, 14, the edges of which register with the fabric edges. Sheets 12, 14 are pressed together by clamps 16, and treating agent 18 is applied to the sides of the pile, e.g. by brush or by spraying. The agent may be a lacquer having a cellulose acetate or vinyl copolymer base; when the lacquer is dry, pressure is released and the pieces separated, or, to facilitate drying and separating, pressure may be released on completion of the application of lacquer. Alternatively, a hot melt such as a mixture of ethyl cellulose and beeswax may be used; or, for soluble fabrics, e.g. cellulose acetate, the agent may be a solvent or a solvent together with a plasticizer. When a solvent is used, the fabric is interleaved with paper or similar separating material.
