Filed: 1930-05-07
Abstract: 339,232. Kellenberger, L., (trading as Kellenberger & Co., L.). May 13, 1929, [Convention date]. Milling-machines.-In a milling-machine one or more spindles have their main bearings in members in fixed axial relation to the cutters, the members being slidable both inside and outside of the frame standard on a supporting arm, so that the cutter may work over the entire working travel. A cutter spindle F is supported in a bearing g carried in a member h which moves axially with the cutter and spindle, the latter being thus always supported in the same position. The axial movement is effected from a hand wheel through a screwed shaft m and bevel gearing n. An extension i of the spindle is slidably keyed to a pinion t<1> and is driven thereby from a belt pulley r through gearing. An arm k on which slides the member h, may be stationary. or slidable independently of the spindle in a guide way L<11>, Fig. 3, on the machine standard b, Fig. 1. The modification shown in Fig. 3 has two cutter spindles F, F<1>, supported in the member h which has a second guiding surface u. Another form is described in which two independently adjustable members h each carrying a cutter spindle are mounted side by side. Several cutters mounted in staggered relationship may be employed. In all cases the cutter e together with its spindle bearing may be housed completely in the standard b.

Abstract: 673,043. Flexible pipes. HOOVER, Ltd. June 7, 1950 [June 14, 1949; May 19, 1950], No. 14189/50. Addition to 648,562. Class 99 (ii) A hose particularly for suction cleaners comprises at least one tubular layer 11 of flexible elastomer, such as polyvinyl chloride, surrounding a spring wire winding 10 and pressed into corrugated form by a flexible cord 12, which may be of polyvinyl chloride, that is wound under tension and between the adjacent convolutions of the winding and bonded to the layer as by a solvent comprising toluene and methyl ethyl ketone, in equal parts, or by heating, Fig. 7. The coils of the winding may be formed on the mandrel of a lathe-like machine and tensioned circumferentially by a split grooved nut to grip the mandrel so that there are approximately one per cent more coils than there were initially in the unstressed state of the winding. The tube 11 which in the unstressed state has an internal diameter equal to the internal diameter of the winding is then passed over the winding with the aid of air pressure and the cord is applied to corrugate the tube, a dispensing device applying a solvent to the tube ahead of the cord winding position, Fig. 1 (not shown). The hose is then assembled on a second mandrel of reduced diameter and collapsed axially to relieve the cord tension and to cause the tube to contact a substantial portion of the circumference of the cord, Fig. 5 (not shown). Alternatively, the hose may be placed on a hollow mandrel and collapsed by suction, Fig. 6 (not shown). The hose is placed in an oven and heated at a controlled temperature to bond or fuse the tube and cord.

Filed: 1955-05-23
Abstract: 806,746. Pyrophoric lighters. COENDERS, A. May 23, 1955, No. 14819/55. Classes 75(1) and 75(3) In a pyrophoric lighter in which a friction wheel 9 co-operating with a flint 5 is rotated by the cover 10 of the lighter and in which a wick 24 is movable in a wick tube 16, the latter is adapted to be moved down as a result of the closing of the cover 10 and is provided with a sealing ring 19 which shuts off the supply of liquid fuel to the wick when the cover is open. The friction wheel 9 is connected to the cover 10 and is rotatably mounted on a shaft 8. A leaf spring 11 passes round the shaft 8 and has one limb secured to The cover and the other limb adapted to bear against the top of the wick tube 16 when the cover is closed. The cover is held closed by a projection 12 thereon engaging a hand catch 13 retained by a shaft 14 and loaded by a spring 15. The sealing ring 19 is supported by a bead 20 on the wick tube and, when the cover is open, presses against a flange 21 on a sleeve 22 surrounding the upper end of the wick tube and carrying a sealing plus 23, the sleeve and plug being held in an annular cup in the top of the fuel container in such manner that the plug projects above the top of the fuel container. When the cover is closed the sealing ring 19 is spaced from the flange 21 and liquid fuel then passes between the sleeve 21 and the wick tube and through openings 27 in the wick tube to the wick. The wick tube is slidably mounted in a sleeve 17 inside - the fuel container and is loaded by a compression spring 18. The wick consists of a bundle of fibres, e.g. glass fibres, folded around one narrow edge of a metal strip 25 so that the fibres extend along each surface of the strip parallel to a long side. The strip and fibres are held in a helical spring 26 anchored in the wick tube by a leaf spring 29. As the cover is closed an extension 11a on the leaf spring 11 engages the upper edge of the metal strip 25 and forces the wick into the wick tube.. The extension 11a then engages the upper edge of the wick tube and forces it downwardly. In the closed position the extension 11a presses on the sealing plug 23 to seal the container. The sealing plug 23 is protected from the flame by a ring 28 which may be formed in one piece with the spring 15 of the hand catch and which, when the cover opens, moves upwardly to the position shown.

Abstract: 463,463. Interrupters. MELCHER, A. A., VANDERPOEL, A. G. H., SEWARD, D. E., O'LA VERTY, J. P., and HAPKINS, D. N. May 27, 1936, No. 14993. [Class 38 (v)] An ignition interrupter of the type in which a pivoted cam is rocked to make and break contact with a relatively fixed contact by engagement of a. rotary cam, has a member which is mounted for rotary movement on an axis offset relatively to the axis of the cam, which rotary member carries the breaker arm and fixed contact and is adapted to be displaced by means controlled by the velocity flow of the gas-air mixture through the carburetter induction pipe. As shown in Fig. 1 the contact breaker arm 21, 22 and its co-operating fixed contact 24, 25 are mounted on a ring 19 which is rotatable about an axis eccentric to that of the contact-operating cam 11. The ring 19 is connected by a link 28 to a diaphragm 30 subjected at its opposite face to the suction of the induction pipe 34. When this is at a small value as during idling periods of the engine the spring 35 holds the parts in the positions shown but on increased suction due to opening of the throttle T the spring 35 is overcome and the flexing of the diaphragm rotates the ring 19 to the position shown in Fig. 2. Owing to the eccentric mounting of this ring in relation to the cam axis the " dwell " of the contacts is thus increased with higher engine speeds so that the time during which the coil is magnetized is correspondingly lengthened and efficient sparking in the cylinders is assured. In addition, the movement of the contact-breaker arm is arranged to produce an automatic advance in the sparking in proportion with increase of engine speed although the present arrangement may be employed in conjunction with the known centrifugal arrangement for this purpose.
