Title: Improvements in or relating to means for adjusting the gear shift mechanism of multi-speed hubs
IPC: G05G5/06
Filed: 1956-03-09
Abstract: 789,153. Change-speed control. FICHTEL & SACHS AKT.-GES. March 9, 1956 [March 11, 1955], No. 7554/56. Class 80 (2). A gauge 21, for use when adjusting the length of a cable controlling the position of a ratio selecting pull rod in a bicycle multi-ratio gear hub, comprises a body portion having a number of measuring surfaces 22a, 22b, 22c corresponding to the various ratios and a mounting portion 23 approximately conforming to the shape of a chain guide nut 32. The usual pull chain 33, passing through the nut 32, is connected to the selector rod and is secured to a pin 34 on which is threaded a knurled nut 35 and a turnbuckle 36 connected to a Bowden cable (not shown). To adjust the length of the cable &c. and obtain correct establishment of the ratios, a control lever mounted on the handle bars of the bicycle and connected to the end of the Bowden cable is set in the high ratio position. The turnbuckle 36 is unscrewed to slacken the cable &c., and the nut 35 is screwed along the pin 34 until it lies on the gauge surface 22a. The control lever is moved to the next ratio position, and the turnbuckle 36 adjusted on the pin 34 until the nut 35 lies on the gauge surface 22b. The nut 35 is then screwed up against the turnbuckle 36 to lock it in position. The gauge can now either be turned through 90 degrees on the chain guide nut 32 so that it does not interfere with the operation of the selector mechanism, or it can be completely removed. The surfaces 22b, 22c can be used instead of the surfaces 22a, 22b if the surface 22a is not readily accessible. In one modification, Fig. 3 (not shown), the gauge is formed from a single strip bent over at the bottom to form a hole receiving the chain guide nut, to which it may be clamped by a nut and bolt. In a further modification, Figs. 4, 5 (not shown), the gauge is formed from a single strip bent over to make a recess for the chain guide nut, and a single measuring surface is provided on the edge opposite to the surfaces 22a, 22b, 22c. This single surface is used in co-operation with an indicator member, Figs. 10, 11 (not shown), slidable on an unthreaded portion of the pin 34.

Abstract: 700,377. Handle-bar control mechanism. SOC. D'APPAREILS DE CONTROLE ET D'EQUIPMENT DES MOTEURS S. A. C. E. M. April 2, 1951 [April 6, 1950], No. 7615/51. Class 136(1) [Also in Group XXVII] A device for controlling the brake of a light motor vehicle such as an auxiliary engine bicycle comprises a lever 5 pivoted to a rotary handle, pulling of the lever towards the handle operating simultaneously the brake and a part which influences the working of the engine and rotation of the lever and handle about the axis of the handle acting only on the last mentioned part. A support 3 is rotatably mounted in the end of a handle bar 1 and carries a lug 9 which is movable in a slot 10 in the handle bar and engages in a hole 12 in a tubular piece 11 which carries a sheath 13. The lever 5 is pivoted to the support 3 about a pin 4 which also serves to grip the inner wire 6 of a Bowden mechanism. A link 14 connects the lever 5 to a valve 15 which controls the fuel mixture intake of the engine. A spring 16 is interposed in the link. A rod 17 connects the valve 15 to a lever 18 which, when the valve 15 is open is out of contact with the valve 19. A spring 23 urges the valve 15 towards its open position. When the brake lever 5 is actuated to bring it from position A to position B (Fig. 1), the valve 15 is closed and the decompression valve opened. The spring 16 is stronger than the spring 23 so that between the positions A and B spring 23 yields and not spring 16. To slow down the vehicle without stopping it the handle 13 is rotated so that the end of the lever 5 comes from position A to position C (Fig. 1) and the valve 15 is closed and the decompression valve opened by rotating the handle 13 to bring the end of the lever 5 into position C. Specification 620,567, [Group XXVII], is referred to.

Filed: 1973-02-19
Abstract: 1411178 Automatic control of screw-cutting OKUMA MACHINERY WORKS Ltd 19 Feb 1973 [17 March 1972] 8024/73 Heading G3N A screw-cutting system to be used in numerically controlled machine tools is arranged so that the generation of screw functions of different successive pitch portions is carried out without intermission and the starting point of the screwcutting operation is determined only once at the initiation of the screw-cutting operation. As shown, a data block representing a screwcutting operation is read from a tape by a reader 101 and transferred through gates 112-114 into buffer registers 118-120. On completion of a previous data block, gates 123-125 are enabled by a pulse G1 and the programmed pitch F is transferred to a register 104 and length Z to a register 103, and the operating mode G transferred to a register 102. The contents of the register 102 enables a gate 117, allowing a pulse from a generator 110 to set a starting-point flip-flop 111. The generator 110 is coupled to a main spindle of the machine-tool and provides one pulse for each revolution, whereas a generator 109 provides pulses at a rate of five pulses per revolution. The setting of the flip-flop 111 enables an AND-gate 116 which passes the contents of the register 104 and the pulse train, from the generator 109 through an AND-gate 115, to a mathematical unit 105 deriving a function, representative of the length of thread cut, which is held in a register 106 and compared with the contents of the register 103, by a comparator 107. At equality, the gate 115 is closed and through an inverter 108 and a gate 122 the flip-flop 111 reset. When further screw-cutting data is present in the buffer stores 118-120 the signal from register 102 through an inverter 121 inhibits the gate 122 and by preventing the resetting of flip-flop 111 permits the immediate continuation of screw-cutting according to the further data.

Abstract: 267,718. Chadwick, C. March 26, 1926. Paper bags and the like, making.-In a machine in which paper bags &c. after being dried by a heated drying cylinder 5 are ejected at considerable speed on to a delivery conveyer &c. 10, the conveyer travels in a direction laterally of, or at right angles to, the direction in which the bags &c. issue from the drying cylinder so that they overlap each other laterally. The conveyer is actuated by a worm 13 and worm wheel 14 which rotate a disc 16 carrying a pawl 17 adapted to engage a ratchet wheel 18 on a flexible shaft 15 operatively connected to the shaft 19<a> of a roller 19 around which the conveyer passes. As the bags &c. drop on to it, they are adjusted longitudinally by an adjustable stop 11, and to separate them into batches the conveyer is given a periodic " kick " to move it at more than its normal speed. To effect this, a lever 26, Fig. 4, mounted on rock shaft 24 is oscillated periodically by a face cam 21 on a shaft 20, the, cam engaging a lever 23 on the shaft 24. The lever 26 at its outer end is connected to a lever 28 loosely mounted on the shaft 19<a> and a pawl 29 on it engages a ratchet 30 secured to the shaft. When the cam 21 has withdrawn the lever 26 to its furthest position from the shaft 19<a>, a spring 31 returns it quickly and the pawl 29 rapidly rotates the wheel 30 and shaft 19<a>, the ratchet wheel 18 overrunning the pawl 17.
