Title: Improvements in or relating to combined conveyor and fabric folding devices
IPC: D05B35/04
Filed: 1962-09-07
Abstract: 978,905. Folding fabrics. G. M. PFAFF A.G. Sept. 7, 1962 [Sept. 9, 1961], No.34275/62. Heading B5K. A device for conveying a fabric workpiece to a processing (e.g. sewing) station and folding the fabric during the conveying comprises a surface with folding flaps and drive means for the folding flaps including elements displaceable with the folding flaps and stationary elements in the conveying path of the device. In the form shown, the device 6 is horizontally movably mounted on rails 1 (see Fig. 3), and vertically movably mounted on guide rods 3. The lower surface 9 of the device has folding flaps 12, 13 and stationary inserts 10, 11, the flaps and inserts each being hollow and containing a vertically movable slide 23 carrying barbed needles 40 such that when the slide is depressed by a spring 43 the needles pass through openings 41 in the base of the flap or insert 10, 11, 12 or 13. In operation the device is lowered on to a fabric workpiece 62 lying on a table 63. The table has bevelled edges 64 to displace pawl catches 30 during the lowering so that the slides 23 in the insets and flaps 10, 11, 12, 13 are depressed and the needles 40 pierce the fabric. The device is then raised, carrying the fabric with it, and the horizontal conveying motion begins. During this motion a gear 47 mounted on a cranked shaft 15, 16 which carries the folding flap 13, engages and is rotated by a stationary rack 61 so that the flap 13 is folded, together with an end strip of the material, into the position shown in Fig. 6. During folding the needles 40 of flap 13 are retracted by slide 23 since pins 28 attached thereto are displaced by contact with the underside of flap 12; the fabric is then held by the needles of flap 12 only. The driving connection between gear 47 and the cranked shaft 15 is by way of friction discs 48 such that when element 13 is fully folded slip occurs and drive is no longer transmitted. When gear 47 runs off rack 61, flap 13 is returned to its starting position by a spring 58 which is wrapped about a member 51 fast on shaft 15 during folding. Flap 12 is then turned on to insert 11 in a similar fashion by its associated driving gear 47a contacting a stationary rack 61a; the flap 12 is then turned back to its starting position. At this stage the fabric has a double fold at one end and is held by the needles associated with inserts 10, 11. At the completion of the horizontal conveying phase the device is lowered to deposit the fabric on a processing (e.g. sewing) table 63, needles being provided on the table to retain the fabric when the needles associated with inserts 10, 11 are retracted and the device moved away.

A fastener for anchoring a length of webbing to an anchor member 70 comprises three superimposed plates 10, 20, 30 connected together near one end so that the central plate 20 can pivot relatively to the plates 10, 30, the latter each being formed with an elongate slot 11, 31 and each having a first longitudinally extending abutment 13, 33 at the end of the plate nearer the pivot 50 and a second longitudinally extending abutment 14, 34 shorter than the first at the other end, while the central plate is formed with an elongate triangular slot 21 wider at the end thereof remote from the pivot and has a length portion its ends greater than the length of each of the outer plates between the slots of the abutments of the latter but less than the distance between the outer ends of the abutments. A bight of the webbing engages the slots in use and the triangular shape of the slot in the centre plate permits the relative pivoting. When the fastener is passed through a slot 71 in the anchor member 70 the abutments of the outer plates engage its undersurface to anchor the webbing to the anchor member. The plates 20, 30 can only be engaged with the anchor slot 71 when the plate 20 is out of alignment with them and pushing the plate 20 into alignment with the plates 10, 30 locks them in the anchor slot since the opposite ends of the plate 20 engage the ends of the anchor slot. Each of the plates 10, 20 is provided with an inwardly directed detent 17, 37 which each overly the centre plate 20 and prevent unwanted movement from the locking position. In a modification the plate 20 is provided with a lug which projects to one side and engages an open ended slot in one of the outer plates.

Abstract: 358,345. Stapling books. LœTOLF, O., 9, Davidstrasse, St. Gallen, Switzerland. Nov. 20, 1930, Nc. 35019. Convention date, Nov. 20, 1929. [Class 89 (iii).] A machine for stitching folded sheets into bound volumes by simultaneously clinching rows of staples arranged in the last folds of the sheets, comprises rows of pressure plates for closing down the staple legs, and guiding plates arranged between the pressure plates and adapted to support the staple legs, which have hooked ends, against lateral deflection. As shown, the machine can deal with four rows of staples It comprises two box-like frames 20, 28, and a pressure plate 29 vertically movable by means of a screw 30. The frame 28 is carried by a frame 32 pivoted at one side on a rod 33 and provided at the other side with rolls 35 engaging cam discs 36 on a driven shaft 27. The frame 20, which is guided by the plate 29 and is adapted to slide within the frame 28, is carried by a frame 21 which is pivoted on a rod 23 and has a roll 25 engaging a cam disc 26 on the shaft 27. The frame 28 carries cross-bars 62 and slidable rods 63 on which the work is supported. The plate 29 carries four thrust plates 38, on each of which a series of pressure plates 40, for closing the staple legs, is mounted. These plates are spaced apart, in accordance with the spacing of the staples, by plates 42. The plates 40, 42 are adjustably clamped on the bars 38 by rods 44. Pairs of opposed guiding plates 48 adapted to enter the spaces between the pressure plates 40 are carried by frames 49, which are pivoted at 57 to the frame 20 and have pins 58 engaging cam slots 59 in the frame 28. Pressure blocks 67, 68, Fig. 3, are arranged above the frame 28. In use, the book block 70, Fig. 14, with projecting staples 71 is placed between the blocks 67, 68 upon the cross-bars 62 and rods 63. The shaft 27 is then rotated, when the discs 36 first raise the frame 28 until the bars and rods 62, 63 engage the blocks 67, 68, bringing the work up to the correct level. The pressure block 68 is then moved towards the block 67 to clamp the work. Continued rotation of the shaft 27 causes the frame 20 to rise until the heads of the guiding plates 48 approach the work. The frame 28 then sinks, when the cam slots 59 cause the plates 48 to move towards each other, so that their heads 60 lie between the staple legs 72 to support them against lateral deflection. The plate 29 is then raised by the screw 30 so that the plates 40 engage and close the staple legs.

Title: Variable-ratio frictional drive gears
IPC: F16H61/662
Filed: 1971-07-27
Abstract: 1392707 Variable speed gear ROTAX Ltd 13 July 1972 [27 July 1971] 35318/71 Heading F2D  In a toric disc friction gear, for, e.g. constant speed drive of an aircraft alternator, wherein processional roller-tilt shift is initiated by tangential shift of roller carriages, the tangential shift is effected through an articulated link 33 by axial movement of an inner piston 35, which slides in a slidable outer piston 36 under the influence of the following forces. The leftward thrust of the link 33 under roller torque reaction is opposed by line pressure supplied by a pump through port 39 and passages 45 ... 51 to a space 52 ahead of the inner piston 35, and by output speed responsive governor pressure supplied from line port 39, through the above named passages, port 40, output driven centrifugal governor valve 28, port 42 and passages 57, 58 to a space 59 ahead of the outer piston 36. After a predetermined rightward travel of the inner piston 35 relative to the outer 36, a land 55 on the inner rides off an exhaust passage 54 in the outer, and thereby reduces line pressure. The arrangement is such that, during steady load state, line pressure acting in the inner space 52 on the area of the inner piston 35 balances governor pressure acting in the outer space 59 on the larger area of the outer piston 36, so that a constant ratio (that between the piston areas) exists between line and governor pressures and 66 is restored after every load change, output speed being held to the required value by the governor valve spool 67 occupying a position with a land 69 midway over the output port 70. Since the steady state forces in the spaces 52, 59 balance, the only force acting on the shift link to oppose torque reaction is that of the pressure in the space 52, and this pressure is transmitted to separate pistons of the remaining roller carriages to produce simultaneous shift thereof, and is also fed to an end-loading piston (23, Fig. 1, not shown), for applying traction pressure to the rollers.
