Abstract: 643,520. Knitting-machines. HOLCOTT ENGINEERING CO., Ltd. Nov. 12, 1947, No. 30053. [Class 74 (ii)] A mechanism for controlling the parallel spliced area in the foot of a stocking comprises bluffing means, carried round with the splicing control ratchet-wheel, which prevents racking for a period and then is displaced when the parallel area is complete. In one embodiment the bluffing means, comprising an arm 9 coaxial with the ratchet-wheel 6, is held frictionally against the wheel 6 by a spring- loaded screw 33 in a slot 14. The arm 9 is set against an adjustable stop 17 and as its bluffing nose 11 raises the claw-bar 7, a pin 23 secured to it, raises a beak 20 on a link 19 and is engaged behind the beak. A lug on the pattern chain displaces the link 19 to pull the arm 9 clear of the claw-bar, when racking recommences. The arm 9 is reset against the stop 17 by'the engagement of the pin 23 with a spring-biassed stop 34. In another embodiment the arm 9 is reset by being spring biassed towards the stop 17. In order to prevent the machine starting with the claw-bar bluffed (e.g. after hand turning of the machine), a second lug on the pattern chain operates the link 19 prior to commencement of splicing.

Title: Controlling means for change-speed gearing
IPC: F16H63/46
Filed: 1921-11-11
Abstract: 173,214. Zaparka, E. Dec. 22, 1920, [Convention date]. Addition to 171,095. Controlling variable-speed gearing.-The parent Specification describes operating-means for motorvehicle change-speed gearing in which slidable selector rods 4, 4<1> have heads 5, 5', Figs. 1 and 2, engaged directly by cams 3, 3<1> which are slid laterally to select and turned to operate the rod selected. According to this invention, the cams are slid axially by a spring. The cams 3, 3<1> are secured to a sleeve 2 slidable upon a shaft 1 which is oscillated by the act of operating the main clutch. The sleeve 2 is connected by a linkage 17, 12, Fig. 3, to a lever 7. A leaf spring 9 connects the lever 7 to a hand-lever 8 moving over a quadrant 13, the spring tending to make the lever 7 follow the lever 8. In changing speed, the lever 8 is moved to the new position. The spring 9 is strained because the cam 3 is retained by a plate 16, Fig. 2, upon the head 5 until that head and its rod have been moved to neutral. The act of depressing the main clutch pedal through a lever 6, Fig. 1, turns the shaft 1 and brings the gearing to neutral. The cam sleeve 2 then shoots to its new position as the spring 9 brings the lever 7 up to the lever 8. On release of the clutch pedal, the clutch spring returns the shaft 1, causing the selected cam and rod-head pair to function to bring in the new speed. As shown in Fig. 1, the cams 3, 3<1> are kept from sliding by engaging the sides of the heads 5,5<1>. In a modification, shown in Fig. 5, the heads 5, 5' are bent.

Title: Stud driving device
IPC: B25B23/10
Filed: 1961-08-22
Abstract: 920,402. Screwing-up studs. O. BILZ. Aug. 22, 1961 [Sept. 10, 1960], No. 30208/61. Class 83 (3). A stud driver comprises gripping jaws 42 having threads to engage a stud, the jaws being opened when a spindle 1 carrying the jaws is withdrawn from a workpiece, and an axial feed channel 2 through the spindle for feeding studs to the jaws. The spindle 1 is driven through a gear on a sleeve 9 connected by a ball engaging a groove in the spindle. The sleeve 9 is journalled in a tube clamped to the reciprocating head of the stud-driving machine. In operation, for driving studs horizontally, the machine spindle is retracted, causing the end of a collet 8 to engage, and move rearwardly, a magazine. A rod 69 thereby pushes a stud 3<SP>1</SP> into the collet, and the leading stud 3<SP>11</SP> is pushed into a spring-closed bevel collet 58 mounted in a nose portion 56, as shown in Fig. 4. During the forward movement of the studs, the second stud 3a carries with it a collet 36 moving against the force of a spring 35. During the subsequent forward movement of the spindle, the spring 35 retracts the collet 36 together with all the studs except that held by the collet 58. When the leading stud engages the work it is held securely by the collet 58 while the portion 56 moves rearwardly relatively to the advancing spindle, causing balls 51 to press a sleeve 37 against a bevelled edge on the collet jaws 42. The stud thread is thereby gripped securely. Further movement of the spindle causes the balls 51 to move into recesses 53<SP>1</SP> in the jaws, and the spindle to move over the sleeve 37 until dogs 33 on the spindle engage dogs 41 on the sleeve and the stud is rotated. A spring-pressed clutch 25, 26 slips if too great a torque is exerted on the stud. In modifications, the studs may be fed by compressed air or gravity. U.S.A. Specifications 2,492,307 and 2,531,456 are referred to.

Filed: 1929-10-08
Abstract: 335,393. Sperry Development Co., (Assignees of Sperry, E. A.). Oct. 12, 1928, [Convention date]. Sheet recording-apparatus; particular operations.-For detecting inaccuracies longitudinally (or transversely) of rails or road surfaces, the levels at different points on the surface are transmitted to a common member which is located longitudinally of the rail &c. and only transmits differences to the pen. Attached to the journal boxes 13, 14 of a bogey truck 11 pivoted at 12, is a beam 15 extended to 16. When a low piece of track is reached the forward box 14 drops relatively to the near box 13, these movements being communicated by wines 20, 21 to the ends 24, 26, Figs. 5 and 7, of a lever 19 pivoted to a beam 30. A wire 31 is fixed at 27 to wire 21 and at 28 to wire 20. The differences of movement of 20 and 21 are thus communicated to wire 31 which, through sheath 32, operates a pen P<1>, Fig. 8. The record strip C is driven longitudinally and the pen holder 100 is reciprocated transversely by cam 103 from the vehicle wheels. This produces normally a zig-zag record, Fig. 8 : but when pen p<1> is operated by a change of track level the zig-zag record is deformed to indicate the change. This device, is duplicated for the other rail by wires 21<1>, lever 19<1> &c., Fig. 5, wire 31<1>, pen p<11> &c., Fig. 8. When a change of level across the track from rail to rail is encountered the wires 20, 21, 21<1>, &c. are actuated to rock beam 30. This beam is pivoted at 59 and has a sliding block 66 which operates linkage 68, 73, 81, 80, to move a pen P. A gyroscope G connected to lever 80 is used to damp out the effects of the rocking of the spring-supported vehicle. In a modification of Fig. 5 the pivot 81 is a. pin and slot, one.

Title: Improvements in or relating to apparatus for tensioning and twisting binding wires
IPC: B65B13/28
Filed: 1936-11-13
Abstract: 470,606. Wiring packages &c. HOLZBERG, F. Nov. 13, 1936, No. 31119. [Class 45] A wire-tying machine strains a wire round a package &c. by slides moved oppositely to each other by cams on a rotary shaft. The free end of the wire is secured in a clamp 42 at the end of a lever 43, and the wire passes through slots 86, 87, in twisting pinions 84, 85, round the package and again through the twisting pinion slots to a clamp 41 operated by a handle 41a. The clamp 41 is mounted on a block 40, Fig. 3, carried by a slide 14, and the clamp at the end of the lever 43 is governed by a pin 45 secured to the head of a second slide 15, the slides 14, 15 being actuated equally in opposite directions to tension the wire by cams 21, 22, Fig. 5, on a shaft 18. The slides are urged inwards by springs 31, 32 and are guided within a cylindrical casing 4, 5 clamped to and supported by bearings 2, 3, the external surface of the casing constituting a shaft for gear wheels 8, 9 driving the twisting pinions. The shaft 18 is rotated by a handle 50, Fig. 2, and a pawl 52 forming an extension of the handle moves over a non- rotatable ratchet wheel 54, to prevent reverse movement of the handle when released. The ratchet wheel 54 may be depressed axially against the resistance of a spring 60, by a cap 70 to free the pawl 52 thereby allowing the springs acting on the slides 14, 15 to return the handle to initial position. The wire having been tensioned, a handle 91 is swung through half a revolution spring-pressed pawls 98, 99 carried by the handle, engaging the end-faces of cam-projections 100, 101 in order to rotate the gear wheels 8, 9 driving the twisting pinions. On reverse movement of the handle 91, the pawls 98, 99 ride idly on the ramp of similar cams 100a, 101a on the wheels 8, 9 and snap into engagement with their end-faces, so that at each forward movement of the handle 91, the wheels 8, 9 are rotated through half a revolution. At the end of its forward movement, the lever 90 carrying the handle 91 engages a bar 115 coupled to levers 105, 106 provided with notched cutters for severing the ends of the wire. A projection on the lever 90 engages with the base - plate to limit the movement of the handle 91. The wires are held by clamps 80, 81, 82, the clamps 80, 81 constituting fixed cutters co-operating with the moving cutters 106, 105. The use of two twisting pinions and the clamping members 80, 81, 82 results in the twist shown by Fig. 7. The gear wheels 8, 9 are held in the position corresponding to the completion of twist, by spring-pressed pawls 120.
