Abstract: 530,564. Riveting aircraft; punching. AMIOT, F. June 27, 1939, No. 18748. Convention date, July 26, 1938. [Classes 83 (ii) and 83 (iv)] In a machine for riveting aircraft parts &c. one set of tools makes holes in the work and another upsets the rivets between intermittent advances of the tools across the work, the two sets of tools being separated by a distance determined by the pitch of the rivets, and operating simultaneously. The work 1 rests on a support 14 having holes for passage of the upwardly acting tools and spring pressed rollers 16 to engage the stiffeners 2. The machine is controlled by cams, driven by an electric motor through a clutch, which operate switches in the circuits of electromagnets, such as 53<SP>2</SP> and 53<SP>1</SP>. Fig. 6, which in turn operate valves such as 62<SP>2</SP> and 61<SP>1</SP>, controlling the admission of compressed air to and exhaust from cylinders 81, 81a. Fig. 9, pistons of which advance the bolster 4 and hold-up 6 through toggles 77, or cylinders, such as 55, Fig. 6, the pistons 57 of which force oil from cylinders as 59 into cylinders 67, 167, and 88. Fig. 9, to move the sheet clamp 3a down on to the work, to force the punch 3 through the work. and to force the die 5 against a rivet and a spring pressed sheet clamp 84 against the work respectively. The tools 4, 6 are then returned by springs 82, the tools 3, 5, and 84 by oil pressure on the reverse sides of the pistons 71, 87 and the clamp 3a by a key 73 of the punch holder 70 engaging a groove in its holder 68. Another cam then acts, through a similar relay system, to admit pressure fluid through a fixed piston rod, 138, Fig. 2, into a cylinder 38, having a rack 27, Fig. 2a, on one side in engagement with a pinion 28 which is thereby rotated and, acting through a one-way device 26, shaft 25 and gears 24, 23 rotates a worm 20 engaging a fixed rack 21 to traverse the carriage 7, with all the tools, through a distance equal to the pitch required along rails 8, 9. The shaft 25 is then locked by a spring-pressed detent 31 while the cyinder 38 is returned, a cam 37 on the cylinder 38 engaging a lever 34 to withdraw the detent at the end of the return stroke. Rivets are fed to the holes punched in the work by hand or by a device A, Fig. 9, as described in Specification 530,563, operated by compressed air supplied in a similar manner under control of one of the cams. In a modification the machine is controlled by hand so that the tools operate on the work and then, by another hand movement, the carriage advances and a device is provided to prevent either action from being initiated until the preceding operation has been completed.

Filed: 1928-06-29
Abstract: 294,642. British Thomson-Houston Co., Ltd., (Assignees of Rex, H. B.). July 29,1927, [Convention date]. Magnets; electromagnets.-A magnetic circuit has parallel branches magnetized by permanent magnets or otherwise, and electromagnetic means responsive to the voltage of the circuit are provided for controlling the division of the magnetic flux between the parallel branches without disturbine the total flux. The invention is shown applied to the permanent braking magnets 21, 22 of a mercury motor meter, in order to compensate for variations in the braking effect of the voltage electromagnet 17 of the meter due to variation of voltage. The permanent magnets 21, 22 are of C-shape and are provided with softiron pole-pieces 23, 24, between which the damping disc 26 rotates. In order to provide a branch path for inactive flux, the lower pole-pieces 24 are extended towards one another and separated by an air gap 27, and another soft iron member 28 is provided between the upper pole-peices 23 but separated therefrom by an air gap 29. The North and South poles N, S of the magnets 21, 22 are opposite each other so that there are two parallel paths for the flux, one through the disc and air gaps 25, and one through the air gaps 27, 29. The reluctances of these two paths are so proportioned that the flux normally divides equally between them. Coils 32, 33, 34 are wound on the pole-pieces 23 and the member 28, and are connected in series with the voltage coil 18 of the meter so that on a rise of voltage, producing increased damping on the meter disc 13, the flux through the pole-pieces 23 is reduced so as to reduce the damping on the brake disc 26 to the same extent. The coil 34 is so proportioned and connected as to increase the flux through the member 28 to the same extent that the flux through the pole-pieces 23 has been reduced, so as to maintain the total flux through the permanent magnets 21, 22 constant. The magnets 21, 22 may be replaced by electromagnets, the coils 32, 33, 34, in the case of alternating-current electromagnets being energized by alternating-current of the same frequency and phase. Specification 9126/03. [Class 37, Electricity, Measuring &c.], is referred to.

Abstract: 354,010. Latching ignition switches for internal-combustion engines. BOSCH AKT.-GES., R., 4, Militõrstrasse, Stuttgart, Germany. June 21, 1930, No. 18959. Convention date, June 29, 1929. [Class 38 (v).] In double-ignition systems in which two sources of ignition may be switched on alternatively or simultaneously by a rotary ignition selecting switch which may also be axially displaceable to cut out both systems, a timing switch is combined and preferably interlocked with the combined cut-out and ignition selecting switch in such a manner that when the ignition is cut off the timing switch is automatically placed in the position corresponding to retarded ignition. As shown in Figs. 1 and 2, the switches are mounted in a cover 1, the upper switch constituting a combined cut-out and selecting switch and the lower switch controlling the timing. The upper switch has a rotatable and axially-movable insulating cylinder 6 on the periphery of which are metal segments 7 on which relatively fixed contact springs 10 are adapted to bear. Grooves 9 are formed in the periphery of the switch member at positions corresponding to the inner or " cut-off " position and the outer or working position the switch member being moved axially by a pushbutton 2 at the end of a rod 4 on which the switch drum is secured. This switch nay be moved to differemt angular positions corresponding to one, other, or both of the magnetos, by a rotatable handle 14 secured to a sleeve 12 which carries a pin 13 passing through a slot 11 in the rod 4. A cam plate 18 is provided on the movable switch member so as to partake in its longitudinal movements but is held against rotation by a pin 15 secured to the cover 7. The pin 15 also secures a plate 16 behind the cover, this plate having a lateral extension 26 at its bottom end to which is secured one end of a coiled retractive spring 25 surrounding the spindle 20 of the timing switch. This switch is operated by a handle 21 and carries an oval contact plate 22 adapted normally to co-operate with fixed contact springs 23 to switch in a separate retarded interrupter. The spring 25 is mounted within a casing 24 on the timing switch spindle and has its free end passing outwardly through a slot in this casing in the form of a projection 27. On operation of the switch to move into the " advanced " position the projection 27 moves past the raised part of the cam plate 18 which retains the timing switch in this position until the upper switch is depressed to cut out the ignition circuits. This movement similarly displaces the cam plate 18 so that the projection 27 escapes and the timing switch is automatically returned to its " retard " position in readiness for subsequent starting of the engine.

Abstract: 321,464. Wightwick, T. M. May 4, 1929. Mechanical telegraphs.-Relates to order-telegraph apparatus for marine engines wherein the bridge instrument is connected with an electric make-and-break device which is connected in circuit with a signal or alarm device and a cooperating make-and-break device connected with the engine-reversing gear so that upon wrong movement of the reversing gear an alarm is given, and consists in locating the bridge make- and-break device as a unit separate from but actuated by the bridge instrument, while the second make-and-break device is moved axially of the engine control shaft on movement of the latter. Chains or cords 5 pass over pulleys on the spindles of and connect the bridge telegraph with the engine room instrument 1. One of the chains is also passed over a pulley on the spindle 20 of a make-and-break device 8 fixed to the casing 7 of the chains 5. The device 8 comprises an ebonite block 14 provided with fixed contact rings 10, 14, and fixed contact segments 11, 12, 13 over which works a wiper 15 on the spindle 20 carrying contacts 16, 17. A lead 37 connects the ring 10 to a source of current in series with an alarm 9 a lead 39 being connected to a lead 40 joining one of a pair of contacts 26 with one of a pair 27 adapted to co-operate with a pair of contacts' 28, 29 carried by the reciprocating reversing rod 32. The other contacts of the pairs 26, 27 are connected to the segments 11 and 12 respectively. Suppose the handle 6 of the bridge instrument is moved to give the " ahead " signal. The contact 17 is moved into engagement with the segment 12, and the pointer 3 to indicate "ahead" on the engine-room telegraph. If now the rod 32 is moved in the, direction A to " reverse," the contacts 28, 29 will engage contacts 27. This completes a circuit through lead 37, ring 10, contact 16, wiper 15, contact 17, segment 12, lead 41, contacts 27, 28, 29, 27, leads 40 and 39, to the horn 9 which is sounded. A similar actuation is made if a mistake is made in the other direction. In a modification instead of the reciprocating rod 32, a screw is turned to start the engine. This screw is provided with a non-rotating unit carrying the contacts 28, 29. A normally closed circuit may be opened to actuate the alarm and such device may include a relav and a device to minimize risk of failure of the alarm owing to a breakdown of the source of current.
