Title: Electrical Apparatus for Working Reciprocating Tools.
Filed: 1902-07-02
Granted: 1903-06-18
Abstract: 14,774. Vickers, Sons, & Maxim, Williamson, A. D., and Sumpter, C. L. July 2. Switches.-Relates to an arrangement of electric switch or controlling-apparatus for the driving- motor of a reciprocating-tool, such as a planing- machine, in which automatic reversal of the motion is desired together with a higher speed on the return stroke than on the working-stroke. Two switches are employed, one for reversing, and the other for starting the motor. The reversing-switch, shown diagrammatically in Fig. 1 and in section in Fig. 5, is provided with a shaft i carrying three contact-arms a, b, c which work over fixed contacts 1, 2, 3, &c. on a base-plate n. One of the contacts on each arm a, b consists of a carbon block, which is held in an insulated frame wand is pressed against the fixed contacts 1, 2, 3 by a spring x. The other contact consists of a spring y on the same frame w. The shaft of the starting-switch is driven from the same mechanism as the reversing-switch, and carries a fast iron disc d', Fig. 1, and the loose boss of the contact-arms. The contacts a', b<1> on these arms are connected through the coil f<1> of an electromagnet m<1> attached to the boss, and are moved only when the magnet is energized. The switches are in the position shown in Fig. 1 during the working-stroke, the motor field and armature coils f, being connected in parallel to the mains. The reversing- switch is automatically rotated at the end of the working stroke, and passes through a position in which the contacts a, b rest on the fixed contacts 2, 4. The armature g is then disconnected from the mains and connected to a resistance r, and is thereby retarded. An electromagnetic brake may otherwise be introduced into the armature circuit for this purpose. At the completion of the movement, the contacts a, b rest on the contacts 3, 5, and the field circuit is completed in the original direction through the contacts 10, c, 11 and the contacts 20, c', 21. The circuit of the armature g is, however, reversed, and includes the coil f<1> and resistances r<1>, r<2>, r<3>. The magnet m<1>, being energized, is drawn round by the rotating disc d<1>, and the contact b<1> moves over fixed studs to cut out the resistances r<1>, r<2>, r<3>. When the movement of the magnet m<1> and contact-arms carries the contact c<1> beyond the contacts 20, 21, the field circuit is completed through a resistance r<4>, so that the speed of the armature is accelerated. The coil f<1> is also short-circuited by the contacts 14, a<1>, 15, and the motion of the arms stopped. The resistances r<1>, r<2>, r<3> are cut out in the opposite order to that described above when the switches are operated at the end of the return stroke and the beginning of a second working- stroke. A hand-operated starting-switch may be placed in the circuit from the mains to the automatic switches.

The invention is shown in connection with a lathe for driving the leading-screw'12 from the spindle 8. Acircular casing 14 is formed with a central boss 15 by means of which it is mounted on the headstock ; through the axis of the casing passes a pin 16 having a key 17 ; this may be caused to engage with either of the wheels 18, 19 which are driven at different speeds from the spindle 8. Within the casing the pin carries a wheel 22 in gear with an internal wheel 23 mounted on an eccentric boss and formed with a spur ring 24 on its outer periphery. Mounted in a concentric circle in the casing, on pins 30, are a series of pinions 26 of such sizes as to gear properly with the eccentric spur. ring. Another casing 31, mounted on the lathe headstock at 33, is fitted with an eccentric wheel 35 in gear with pinions 34. The casings 14 and 31 may be turned so as to bring any one of the pinions of the former into register with either of the pinions of the latter ; then upon pushing the pinion in the casing 14 into gear with its eccentric wheel, it is at the same time coupled to the pinion in the casing 31 by means of clutch teeth on the meeting faces. Similarly, another casing 43 is pivoted on the headstock at 44 and may be placed so as to couple its wheel 41 to the pinion in the casing 31, and its pinion 45 to the screw 12, or vice versÔ. In a modification, the intermediate casing is dispensed with.

Title: An Improved Electro Magnetic Stopping Device for Shuttle Embroidery and similar Machines.
Inventor: BEYREISS RICHARD
Filed: 1903-03-12
Granted: 1904-02-18
Abstract: 5796. Beyreiss, R. March 12. Embroidery. -Relates to an electromagnetic stopping-device for embroidery and similar machines, in which the breaking of a thread causes a belt to be moved from a fast to a loose pulley. Bent wire riders are mounted on an insulated live wire b, Fig. 5, having a loophole e' through which the thread passes. On the breaking of a thread, the other end e<11> of the rider swings up against another live wire c, completing the circuit and energizing electromagnets in the coils g, Fig. 3. An armature h is thus attracted, raising a rod i and causing a displaceable part i<1>, hinged to it at i<11>, to be raised so that a hook engages with, and is moved for some distance by, a ratchet-wheel k geared to the driving-shaft. A cord or link i<111> on the part i<1> is thus caused to pull a stopping-lever r, Fig. 8, laterally, allowing the belt fork, which is held in a recess r<11>, to move the belt from the fast pulley I to the loose pulley II. To re-start the machine, the electromagnets in the coils s are excited, causing the double-armed lever s<1> to move a toothed sleeve n<111>, having a projecting tooth, up into engagement with a notch on the boss of the loose pulley II. A rack is thus made to travel in the direction of the arrow, and, by means of a bell-crank lever normally held against a stop p by a spring, moves the fork with the belt so that the latter re-engages the fast pulley I. At the end of half a revolution, the sleeve n<111> is disengaged from the boss of the pulley II by a stop u<1> acting against the nose u on the sleeve, the machine having then been started. An insulating-sleeve on the free end of the rider e<11>, preventing closure of circuit when the latter is in the position shown by the dotted lines, enables the use of some riders to be dispensed with.

Title: Improvements in Acetylene Gas Generators.
Inventor: THUBRON DAVID
Filed: 1903-04-21
Granted: 1903-10-15
Abstract: 8953. Thubron, D. April 21. Acetylene.-Consists of an apparatus for generating acetylene by means of a regulated supply of water, with an arrangement for automatically cutting off the water supply when the carbide is exhausted, and a mechanical device for restarting the automatic generation of gas when the carbide chamber has been recharged. When the gas holder O, containing water up to a level Q, sinks owing to the consumption of gas, a stop b strikes a spindle g, thereby compressing a spring s and opening a valve i of india-rubber or like material allowing a further supply of water to be sprayed on to the carbide by means of a pipe e in the carbide chamber c. When the carbide is exhausted, the holder O sinks and forces an india-rubber or like valve i<1> on to a seating m', thereby cutting off the supply of water to the carbide chamber. When the chamber is recharged with carbide, a tap V is opened, allowing a little water to enter the chamber, raising it sufficiently to remove the stop b from the spindle g. The tap V is then closed, and the action becomes automatic until the carbide is again exhausted. The gas generated enters the holder O by way of a non-return valve z.

Title: Process for Producing and Separating Hydrochloric and Sulphuric Acids
Inventor: ASKENASY PAUL
Filed: 1903-06-27
Granted: 1903-08-27
Abstract: 14,342. Askenasy, P., and Mugdan, M. June 27. Hydrochloric acid; sulphuric acid.-According to a known reaction, a mixture of hydrochloric and sulphuric acids can be obtainei by passing chlorine and sulphurous acid into water. According to this process, these gases in the required proportions are led to the bottom of a tower down which water or dilute hydrochloric-acid solution is passed. Concentrated sulphuric acid escapes from the bottom of the tower, and hydrochloric-acid gas from the top. Sulphuretted hydrogen or hot pyritic gases may be added to the entering gases. To ensure that the gas feed is kept uniform, a part of the gaseous mixture enters continuously into fresh water, and any surplus of one or the other of the gases is tested by measuring with a suitable meter the potential imparted by the same to an indifferent electrode in comparison with an electrode of constant potential. The feed of one or other of the gases may be automatically regulated by combining a suitable relay with the testing-device. To obtain absolutely - pure hydrochloric acid, chlorine is added in excess, and the excess subsequently removed from the escaping gas by a reducing medium, such as ferrous chloride, sulphuretted hydrogen, &c.
