Title: Improvements in ticket issuing machines
Filed: 1934-11-12
Abstract: 442,314. Ticket - issuing machines. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, Westminster, and LUCKETT, H. W., 67, Palmerston Road, Plumstead, London. Nov. 12, 1934, No. 32497. [Class 106 (iii)] In recording mechanism for ticket-issuing and other machines wherein the record is in the form of perforations or embossments punched in a strip, the punches are positively operated and positively retracted by a pivoted lever having forces successively applied to it at opposite sides of its pivot. The record strip fed by sprockets 8 passes between a plate 3 and a die plate 4, and the punches 11 straddle levers 10 which are pivotally mounted on a spindle 5 and have bent ends adapted to engage slots or solid portions of the selecting drums 12, 13 carried by arms 14, 15 loosely supported on the spindle 5. These arms are braced together by pins 9, 16 at their two ends, and a spring 19 tends to turn them so as to maintain pinions 17, 18 on the drums 12, 13 in engagement with pinions 20, 21 fast and loose on a shaft 22. The shaft 22 is turned an amount depending upon the value of the fare, and the pinion 21 sets the selecting drum 13 accordingly. The spindle 5 is turned an amount corresponding to the class of the fare, and sets the drum 12 accordingly. Upon operation of the ticket machine, a shaft 25 and cams 24 are turned, the face A of the cam engaging pin 16 and raising the carriage 14, 15 to press the selecting drums 12, 13 on to the ends of the levers 10 and to bring detents 27 into engagement with the pinions 17, 18 to lock the drums. On the return movement of the cam 24, if the carriage 14, 15 has not returned to its initial position under the tension of the spring 19, the face B of the cam engages the pin 16 and positively retracts the carriage. At the same time the pin 9 positively restores the levers 10 to retract the punches. For feeding the record strip, a crank-arm 29 on the spindle 25 first lifts an arm 28, causing a strap 30 to pivot round a spindle 2 and a ratchet spring 32 to click over the teeth of a wheel 31. On the return movement of the spindle 25 the ratchet spring 32 advances the wheel 31 together with the sprockets 8 through one tooth, pinions 33, 34 rotating at the same time to rotate the recordstrip feeding drum. The movement of the ratchet spring over one tooth of the wheel 31 and nearly over two teeth provides a lost motion in the movement of the record strip to ensure that the punches are removed from the strip before it is fed. A second ratchet spring acts as a backstop. A modification is described for operating an individual punch for recording the passing of fare stages. Another modification comprises a further individual punch for recording journey turning points, and includes a bell-crank carrying the punch and reciprocated by a rocking member, and a detent device to ensure correct direction of the stage recordings.

Title: Improvements relating to automatic weighing machines
IPC: B65B1/32
Filed: 1927-12-05
Abstract: 300,804. Smith, A., and Southall, C. Dec. 5, 1927. Automatic - f e e d weighers. - An automatic weighing machine, particularly suitable for weighing out small quantities of tea, is provided with a supply hopper, a pan on a weighbeam and an electromagnetically - vibrated feed regulator, the latter comprising a receptable which is open at its upper side to the lower end of the supply hopper, and is also open at its under side above the pan, the inlet and outlet being separated by a transverse partition which prevents flow of material through the feed regulator excepting when the latter is subjected to an horizontal vibratory movement. The material from the supply hopper h descends upon an horizontal partition i in the feed regulator c and after passing through an orifice j flows down the base of the regulator, and, when the regulator is vibrated, falls through opening z into the weigh pan b. The regulator is supported on a spring-controlled arm d capable of being vibrated in an horizontal plane about a pivot e by an electromagnet or solenoid f. Stops k limit the lateral vibrations of the arm. When the correct quantity of material has entered the pan the tilting of the weigh beam a breaks the circuit and stops the vibration thus cutting off the feed. The material is discharged from the pan by pressing in a knob p thereby causing a bent lever q to rock a gate lever n and open the discharge gate m. If the weighing operation has not been completed a lever t pivoted on the frame and resting on a peg u on the weigh pan, obstructs the movement of the lever q and prevents the discharge gate m from being opened. The lever t moves out of its obstructing position when the weigh pan descends under-its proper charge. In a modified machine, two vibratory feed regulators are provided for delivering course and fine feeds respectively.

Abstract: 486,309. Ironing -machines. BOYLE, E. H., and BAKER PERKINS, Ltd. Dec. 1, 1936, No. 32948. [Class 138 (ii)] Before being fed to an ironing-machine or - press, flat articles such as handkerchiefs, towels or sheets are wrapped in succession upon a core member which is then carried to guides positioned in front of the usual feed tapes and unwrapped on to the feed tapes. This procedure saves smoothing out each article as it is fed to the ironer by the operator and the consequent waste of ironing space. For winding the articles the core 26 may be supported on two rollers 10, 11 driven in the same direction, and the core is driven by frictional engagement therewith. A roller 28 carried by pivoted arms 29 may press on the core to maintain it in contact with the rollers. The articles 27 are lifted by the operator from a box 25, smoothed out and fed over an inclined table 24 on to the core. In a modification the core may be supported by a re-entrant portion of a constantly driven endless apron.

Filed: 1969-06-30
Abstract: 1,253,466. Velocity-modulated tubes. VARIAN ASSOCIATES. 30 June, 1969, No. 32998/69. Heading HID. In a travelling-wave tube having a centipede slow-wave structure-i.e. a coupled resonator structure formed by a sequence of discs axially spaced along a conductive tube, each disc being centrally apertured to permit passage of the electron beam, and having an array of peripherally spaced, radially directed legs, adjacent ones of which are of S-shape and reverse-S- shape respectively-broad-band coupling to an output waveguide is achieved by the use of a transition section of ridged waveguide. The transition section 6 is formed by a length of rectangular waveguide with a ridge 23 projecting towards the output end of the centipede structure from the opposed broad wall of the guide. Both the waveguide and its ridge are tapered, as shown, over a distance of about 2#. A hollow conductive post 24 coaxial with the electron beam and leading into the collector 4 projects from the waveguide ridge into a wave-energy coupling hole 25 formed in the opposite broad face of the guide which closes the output end of the centipede structure. Hole 25 is oval in shape, with its major axis extending perpendidicular to the narrow walls of the guide 6. The. centipede structure may be severed, and may be preceded by a multi-cavity, stagger-tuned klystron input section.

Title: Improvements in or relating to machines for turning and adhesively securing flexiblematerial, e.g. shoe uppers, over edges of rigid material, e.g., shoe insoles
IPC: A43D25/053
Filed: 1952-12-31
Abstract: <PICT:0753459/III/1> <PICT:0753459/III/2> A cement lasting machine of the kind wherein adhesive is applied to the work, e.g. shoe, luggage, upholstery, &c., as it is fed, progressively and continuously, relatively to a point of application of the adhesive, has means for advancing an end of a length of normally solid, non-tacky, shape-retaining adhesive to the point of application where the leading end is rendered tacky and is then guided, in this condition, on to the work.  The adhesive may be made liquid so as to become sticky by the application of heat alone, or it may be subjected to the action of a solvent applied to it as it passes along the guideway, or to the combined action of both heat and solvent.  The illustrative form of lasting machine described has work gripping and advancing rolls 9, 14 and rotary wiper 17, or a reciprocating wiper as described in Specification 541,643 [Group VII], but other work gripping and advancing means may be used.  Thermoplastic adhesive such as polyvinyl acetate in ribbon form, may be supplied from a reel 43, Figs. 2, 3, by a toothed feed wheel 37 on a shaft 36 driven by worm and worm wheel 38, 40 from a shaft 11 on which the roll 14 is carried and which is movable relatively to roll 9, under control of a treadle, to permit the work to be introduced between the rolls.  The wheel 37 feeds the adhesive P through a channel 34 in a block 33, received in a recess in the bearing member 13 for the shaft 11, and through a guide 25 in a housing 23 which encloses it and which is heated over a narrow zone by an embedded resistance coil 28.  The portion of the guide 25 which projects above the housing has radiating fins to prevent overheating of the upper part of the guide and premature softening of the adhesive.  In a modification, Fig. 5 (not shown), the lower end of the tubular guide is vertical and heat is applied to a sleeve at the lower end of the guide by two spaced collars connected to the secondary of a high-frequency generator, so that the adhesive exudes on to the work.  In a further modified form (Figs. 6, 7 not shown), the lower end of the tubular guide is bifurcated to deliver adhesive simultaneously to both the sole and the margin of a shoe upper.  In another modification (Fig. 9, not shown), the adhesive is in the form of a normally non-tacky solid block held in a cylinder with conical base attached to the machine and surrounded by a heating element.  Pressure may be applied to a plunger in the top of the cylinder by a spring, which is prevented from acting when no work is being operated on, or by air pressure applied through a conduit, a valve in which is operatively connected with the feed rolls for the work so that it is open only when there is work between them.  Reference has been directed by the Comptroller to Specification 669,011 [Group VIII].
