Braiding - machines.-Relates to an arrangement for drawing - off the thread from the bobbins of braiding-machines whereby the s'ack due to varying tensionis wound round a spring-control'ed roller p. The spool t is mounted on a tube f connected by a pin d to an upright c on the base g of the carrier g and is free to turn. The top end of the upright - is halved and receives the part k. A plate m which also carries an arched portion n with the roller p is mounted on the part k. The thread s is first passed through an eye i of a turnedup portion h, then down, through an eye u, around a loose disk b, and back to the eye u. The thread also passes between the base g and a clamping- spring v. From the eye u, the thread passes upwards through the hollow axle o of the roller p, and through a slot x in its periphery, to the eye r. The slack of the thread is then taken up by the rotation of the roller p under control of the spring q. When the slack is used up, the tension of the spriog q draws thread from the bobbin past the clamping-spring v.

Title: Improvements in Wireless Telegraph Receivers.
IPC: H03D1/10
Filed: 1913-08-12
Granted: 1914-08-07
Abstract: 18,326. Marconi's Wireless Telegraph Co., and Round, H. J. Aug. 12. Wireless telegraphy.- In a receiving - system, a spark-gap s, vacuum tube, or a pair of oppositely connected valves or crystals, or other device the conductivity of which varies rapidly at a certain potential, is provided with means, such as frequent trains of short waves. for intermittently creating that potential. The local waves may be set up by a shunted buzzer w, j, and are preferably damped waves or intermittent undamped waves such that each train of waves does not last materally longer than one half-period of the oscillations to be received. The spark-gap s &c. is so adjusted that the local waves give no effect in the telephone except when signals are received. When a galvanometer is used as an indicator, the group frequency of the local waves should be equal to the wave frequency of the received oscillations, or to a sub-multiple thereof, so that the condenser c always discharges in the same direction. If the group frequency of the local waves is above the audible limit, and if continuous oscillations are received, the group frequency is thrown slightly out of resonance or subresonance with the received waves, or preferably the trains can be cut up into groups, the group frequency having a musical note which will only be heard when signals are received.

Title: Improvements in Coin-testers.
Inventor: LEAN CLEMENT
Filed: 1913-09-08
Granted: 1913-12-18
Abstract: 20,309. Lean, C., [Allgemeine Handelsges. Bock & Co.]. Sept. 8. Coins, testing.-Coins are tested by passage between feelers, which hold the coins at a higher or lower place according to the impression or inscription thereon, only those coins with the correct impression being held in such position that, on release, they pass into the till. The coinchannel 1 is inclined at the top and provided with an opening from which small coins fall. The lower vertical part ends in two branches, a side one 2 leading to a till and a vertical outlet normally blocked by a lug 4 on a spring-pressed lever 6, a spring-connected arm 16 on which is lifted when a coin is inserted, by the end 15 of a lever 9 which has a pin 8 passing into the channel. The raising of the lever 9 also releases a counterweighted lever 10 which rocks to release a lug on the lever 6. After a predetermined movement, a spring 20 on the lever 6 snaps into a recess in a member 21. The member 9 is also held against return by its end 23 bearing on the end 30 of the lever 6. The coin now falls down the passage between the points of elastic feelers 24, impacting on, releasing, and rebounding from the spring 20, whereupon the feelers, which have sharp spoonshaped ends, catch the impression or inscription and hold the coin, the position and shape of the feelers being adapted to the coin to be tested. Plain disks &c. will rebound further into the path of a projection 26 on the lever 6. The return of the lever, allowed by the release of the spring 20, is thus delayed until the lever 10 has returned and brought a projection in front of a lug on the lever 6. In this position the lug 4 opens the vertical outlet and the coin is rejected when lugs 27 on the lever 10 open the feelers 24 to allow the coin to fall. In another construction the coin is positively driven against the spring stop by a lever which then releases it to pass back between the feelers.

Title: An Improved Straight Pull Breech Action for Military Rifles.
Inventor: STAMM HANS
IPC: F41A3/20
Filed: 1913-05-03
Granted: 1914-02-26
Abstract: 20,949. Stamm, H. May 3, [Convention date]. Breech actions, sliding breech-block. - Relates to straight-pull rifles of the kind in which the bolt is operated by a non-rotary sleeve connected thereto by screwthreads and prevented from rotating when the breech is open by the firing-pin, the lug of which engages, under the influence of the firing-spring, in a notch in the back of the breech-bolt. The invention consists mainly in special means for coupling the cocking-piece and the operating-sleeve to the breech-bolt when the breech is open, and for placing the firing- pin in a safe position. The operating - sleeve 4 has external ribs 8 which, when the breech is closed, fit into corresponding grooves in the breech body and prevent rotation. When the breech is opened, the ribs on the sleeve are disengaged from the grooves, and the locking-lugs on the bolt enter the grooves, thus holding the bolt against rotation. To prevent the sleeve from rotating when the breech is opened, it is coupled to the breech-bolt by the cocking-piece 20 and by a special spring catch 42. The lug 21 of the cocking-piece enters a slot 31, Figs. 3, 4, and 9, in the sleeve 4 and is pressed by the firing-spring into engagement with a notch 23, Fig. 4, at the rear of the bolt. The three parts are thus held against rotation. A spring catch 42, Fig. 6, is also provided to hold the sleeve and bolt against relative rotation. This catch is pivoted to the sleeve and has a nose 42 which enters a recess in the bolt. The catch is released by the breech casing 3 as the sleeve approaches its forward position. The firing-pin 16 is mounted in the non-rotary cocking-piece by a screw-thread and can be rotated through 180 degrees by means of a thumb-piece 26 to retract the point of the firing-pin to a position in which it cannot reach the cartridge. A spring detent 28, Fig. 3, holds the thumb-piece in either of its adjusted positions. The sleeve 18, which forms the rear abutment of the firing- spring 17 and a guide for the firing-pin 16, is screwed into the breech-block and locked by the lug 21 of the cocking-piece, which engages a groove 30, Fig. 3, in its under surface.

Abstract: 3654. Levin, I. H. May 9, 1913, [Convention date]. Gases, obtaining; electrolytes, circulating; electrodes; cells.-In apparatus for making gases such as oxygen and hydrogen, anode and cathode compartments are connected by independent off-take conduits g<4>, Fig. 2, with corresponding compartments b, c of a tank a, the lower part of which may be contracted. A partition d between the latter compartments reaches nearly to the bottom of the tank, where it enters a small trough e so as to prevent transference of bubbles while allowing equalization of pressure in the cell compartments. The electrolyte and gas enter the compartments through nozzles g<3> projecting the liquid on to a surface c<2>, which may be made with baffles to facilitate disengagement of gas. The gases collect in chambers f, g above the tank provided with level gauges. An overhead reservoir for electrolyte communicates by a pipe with the bottom of one of the tank compartments Passages b<1>, c' return the electrolyte to the cells. Lugs a<1> are provided on the tank for the reception of bolts by which sets of electrode frames are clamped against opposite sides of the tank. The frames are separated by the edges of diaphragms or by other packing, and have at top and bottom projections in each of which are two holes n, o, or p, q, Fig. 3, communicating with the spaces on opposite sides of the electrode. Rubber gaskets are fitted in recesses around the holes so that these form, with holes in the sides of the tank, continuous passages for the passage of the electrolyte and gases. Each bipolar electrode is a ribbed or corrugated plate m integral with or fitted in its frame. Notches m<2> in the ribs allow circulation of liquid, and projections m<1> may be provided to guard against warping. The electrodes may be of iron on the cathode side and nickel on the anode side; they may consist of sheets of the two metals, or of iron electrodes nickel-plated.

Title: An Improved System of Connections for Telephone Installations in which the work of the Operators is Supervised from Special Observation Places.
IPC: H04M3/62
Filed: 1914-07-08
Abstract: 16,340. Marks, E. C. R., [Siemens & Halske Akt.-Ges.]. July 8. Electric type-lever machines.-In a semiautomatic exchange telephone system in which a special operator supervises the ordinary operators, the numbers of impulses transmitted by the impulse sender are recorded by a typeprinting recorder. The relay 25, Fig. 10, is arranged in the impulse circuit and is deenergized by each selecting-impulse. The slowrelease relays V1, V2 remain energized during the impulses which make up each digit, and these impulses by actuating the contact 30, cause the magnet D, to drive the arm 31, until at the end of a series, a magnet, as E<3>, is energized over the contacts 29, 33 and the offnormal contact s<1> to operate one of a set of ten type levers, such as 1, Fig. 8. The relay M then brings the magnet D, into circuit with the interrupter U to drive the arm 31 to its initial position. The arm 35 is driven to its second position when the relay V1 is first energized, and is driven to its third position when the impulses of the second digit are received. In this third position the magnet 17 is energized, thus moving the paper carriage in a horizontal direction by means of the pawl 15. After the four digits have thus been printed in a line, the arm 35 is brought on to its last contact, and the relay 21 is operated to connect the interrupter U<1> to the magnet D<2>, thus returning the arm 35 to its inoperative position. The magnet 22, which is energized when the first set of impulses arrives, moves the paper forward one step.
