Title: Improvements in Machines for Coiling Wire.
Inventor: JAMES EDWARD
IPC: B21F3/04
Filed: 1913-04-23
Granted: 1913-10-30
Abstract: 9548. James, E. April 23. Coiling; bending-formers.-In a machine for making wire tubes consisting of two wires coiled one within the other, of the type having a mandrel and offset rolls, the rolls are formed with two sets of corrugations, which are differently spaced, or with one set of corrugations and a smooth portion. In the form shown in Fig. 4, three rolls, symmetrically arranged around the mandrel 7 have corrugations 20 set out of line with each other to form a coil from the wire A, and further corrugations separated by ribs of larger diameter for inserting the second coil B, the mandrel being of smaller diameter from the point at which the second wire is inserted. The ends of the rolls are bevelled at 21 to prevent too sudden expansion of the coils as they leave the rolls. The part of the rolls surrounding the smaller diameter of the mandrels may be smooth, and in this case if the second wire is to be inserted inside the first wire it must be held under tension, which is not necessary if the second coil is outside. The wires may be of any shape in cross-section. The mandrel is secured at one end only by a pin 8 to the driving-shaft 3 through a pinion 5, which through spur-wheels rotates the shafts of the rolls. The upper roll is carried by a lever 13 the position of which may be adjusted by a screwed rod 16 passing through a slot in the frame, between which and the hand-wheel 17 is inserted a spring. The rolls may be idle, the wire being in that case positively fed. The machine may be employed to form single wire coils by omitting to supply a second wire thereto.

Granted: 1914-01-29
Abstract: 14,684. Hartshorn, E. F. Feb. 5, [Convention date]. Window b l i n d s.-An awning of the kind described in Specification 14,683/13 consists of a shade 1 carried on a spring roller 2 m o u n t e d on spreaders 4, 4, which are strengthened at their corners 6 and are pivoted at 11 between ears 10 on a slider 9 which travels on flv-rods 20 on the window frame. The s l i d e r s 20 are pressed from sheet metal into partly circular form, and have three pairs of ears, the upper ones 14 supporting a roller 15 which holds the shade in position. The middle ears 12 carry a fibre roller 13 against which the spreaders may fold in raising or lowering. One or more halliards 7 are attached to a perpendicular arm 8 on the spreader cross-bar 5, the arm 8 serving to keep the halliard 7 from the shade 1. Another halliard 16 is attached to the slat 3 at the upper end of the shade 1. Both halliards pass over pulleys 17, 18 and are secured to a cleat 19. To spread the awning, the halliard 7 is slackened and the halliard 16 pulled. Pulling the halliard 7 raises the spreaders 4 with the spring roller 2, and, if continued, raises the sliders 9 up the fly-rods 20. When the halliards do not properly run through the pulleys 17, 18, after the spreaders 4 have been raised, as in Fig. 8, and it is desired to lower the awning, use is made of one or more leaf springs 22 secured to the underside of the spreaders and pressing on the ears 10, the springs being then distorted and tending to force the spreaders down.

Title: Improvements in Automobile Torpedoes.
IPC: F42B19/20
Filed: 1913-07-15
Granted: 1914-08-17
Abstract: 16,290. Vickers, Ltd., and Smith, F. E. July 15. Air and gas heating furnaces. - Relates to means for heating the motive fluid of torpedo engines, of the kind in which the heating-substance is a solid selfsustaining combustible, and the products of combustion are not mixed with the motive fluid. According to the invention, the compressed air or other fluid is caused to travel along a helically-coiled channel or conduit adjacent to a second helicallycoiled channel along the wall of which the products of combustion pass. This is preferably effected by placing the conduits one inside the other in the forms of helically-coiled tubes, air and products of combustion passing through their respective tubes in opposite directions. In the apparatus shown, the products of combustion pass from two cartridges B, Figs. 1 and 2, connected by a transverse conduit C, along a helically - coiled flue - tube C<1> to the exhaust which is provided with an adjustable spring-loaded valve D so as to control the pressure of the exhaust and thus the rate of combustion. The compressed air travels from the reservoir E<Î>, Fig. 2, through the reducing- valve E<ÎÎ> and pipe e to a tube E, wholly surrounding the flue-tube C', and subsequently through a set of small tubes E<1> wholly contained in the flue-tube C'. Each of the tubes E<1> is preferably twice bent back upon itself so as to take the air three times along the full length of the flue-tube C<1>. Finally, the compressed air passes through an annular space c around the conduit C, and by a pipe E<2> to the engine. Water or other liquid may be vaporized, or gas such as oxygen may be heated in annular heating-spaces c<1>, c<1>, around the conduit C and thence led to the coiled tube E with the cold air so as to traverse the heating-system therewith. The water is stored in a U-shaped flask F arranged transversely to the axis of the torpedo, and connected at the bottom by a pipe f<2> to the heating-apparatus, and at the upper part of both limbs of the U by a pipe f<1> to the compressed-air supply, which causes the flow of the water.

Title: Improvements in or relating to a Pivoted Pulsometer used for Massage Purposes.
Inventor: MASCHTALIR KIRILL
Filed: 1913-08-13
Granted: 1914-07-30
Abstract: 18,435. Maschtalir, K. Aug. 13. Diaphragm pumps; steam-pumps. - A pulsometer for hydraulic massage is characterized by separate chambers being provided for the liquid to be pumped and the driving fluid, the chambers being separated by an elastic membrane m impermeable to steam. Instead of steam, vapours of alcohol, ether, &c. may be used. The steam &c. passes from a heated chamber b through a hollow spindle c and pipe d to a distributing box e, and thence through an opening f and pipe i to the chamber k, which is separated from the water chamber l by the elastic membrane m. The expansion of the membrane expels the water from the chamber l through a valve p into a chamber q communicating with the nozzle u. The water in the chamber l<1> causes the apparatus to swing over on the spindle c and the valve y falls away from the opening f<1> and covers the opening f so that the steam passes to the chamber k<1> and expels the water from the chamber l<1> into the chamber q. During this time, the steam in the chamber k condenses and the membrane m collapses so that water flows into the chamber l through the valve z, the valve p being meanwhile closed by the pressure in the chamber q. The nozzle u may be enclosed in a bladder and the bladder may be connected by a pipe to a heater so that the water may be heated and returned for re-use in the chambers l, l<1>.

Granted: 1914-04-09
Abstract: 22,822. Zeise, R. Oct. 9. Drawings to Specification. Paper, wood, and fibrous pipes and tubes.-Quills to form paint-brush handles are heated until soft, widened at the large end to receive the tuft, and inserted in straightening moulds in which they are allowed to cool gradually. The quills are first cleaned and scraped, and then softened by boiling in water which may contain alkali or grease which may be in a closed vessel. The ends of the quills are closed so that the quills swell by the expansion of the internal gases, the expansion being confined by tubes or funnels to the large ends. The quills, which may be bleached by hydrogen peroxide, are then slowly inserted in bores in the heated moulds and allowed to cool. Finally they are cut across the flared end, grooved round the flare, polished, and varnished.

Abstract: 6970. Craig, E. E. March 19. Electric clocks.-Relates to electro-magnetic stepby - step mechanism, particularly applicable to secondary electric clocks, of the kind in which an armature having polar extensions is caused. to rotate intermittently by the successive energization of electro-magnets arranged in a circle around the armature. According to this invention, there are only three line-wires a, b, c in the system, the wire c being a common return wire. The electromagnetic pole-pieces A, A<1> and B, B<1>, &c. surrounding the armature are connected in pairs successively to a source of unidirectional current X through the lines a, b alternately, by means of the contact-device S at the transmitting-station. The polar extensions of the armature M constitute leading-horns H, as shown. In order to prevent overshooting, the intermittent currents are prolonged for a second or two longer than is necessary for producing each step, while residual magnetism in the electro-magnets may prevent accidental movement of the armature between the impulses. The spindle D of the armature may be vertical, driving time-indicating or other mechanism through worm-gearing, as shown in Fig. 4.

Abstract: 9065. Collis, A. G., and Crompton & Co. April 9. No Patent granted (Sealing fee not paid). Protective arrangements. - Alternating- current distribution systems are protected against reversals, faults, &c. by connecting the secondaries of a current transformer C and a potential transformer D in a closed auxiliary circuit containing a fuse E, the circuit - breaker trip-coil A being connected in parallel with the fuse E. Disturbance due to abnormal conditions brings about the blowing of the fuse, followed by the energization of the trip-coil A controlling an automatic circuit-breaker B. In the case shown, the windings C, D are connected in opposition so that normally no current flows through the fuse, the arrangement being responsive to reversal. Alternatively, the transformer secondaries may be connected in conjunction so that the fuse normally carries current and blows upon overload. The arrangements are applicable to two-phase and threephase systems and to duplicate feeders, ring- mains, &c.

Granted: 1915-04-01
Abstract: 13,524. Western Electric Co., [Woodward, F. T., (acting fur Western Electric Co.)]. June 3. Switchboards; electro-magnetic switches. - A switching-apparatus for selectively closing any one or more of a number of circuits comprises groups of spring contacts for the different circuits mounted adjacent to the points of intersection of sets of vertical and horizontal shafts, and adapted to be selectively operated by rocking a shaft of each set. The contact-operating devices are constructed so that a given set of contacts is only closed when the corresponding vertical and horizontal shafts are operated in the order named. The means for rocking the shafts 1, 2 consist of magnets 17, 18, the armatures of which may also control groups of springs 19, 20. The springs 19 are controlled by rollers 23, while the springs 20 are operated by buttons 42 on frictionally-pivoted lugs 49 with which armature-pins 32 engage after a certain amount of lost motion. The springs 20 are normally closed and are in the circuits of the corresponding magnets 18, so that when one of these magnets is energized it immediately opens its own circuit. The armatures 28 of the magnets 18 are, however, self-latching, each armature carrying a finger 29 which co-operates with a pivoted locking-plate 31, so that a shaft which has been operated by the momentary energization of its magnet remains displaced until the locking-plate 31 is depressed by the energisation of another magnet. The construction of the contact-operating devices is shown in Fig. 2. The vertical shaft 2 carries a flexible bent wire 45, 48, which ends in an upturned hook 49 and is kept in position by a rigid arm 47. When the shaft 2 is oscillated, the hook 49 is brought over the operating-head 52 of the group of springs 3, 4, 5, 6, and if the shaft 1 is then also oscillated, an arm 46, acting through the upturned hook 49, closes the circuits 3, 5 and 4, 6. The shaft 2 may then be released without opening these contacts, the hook 49 remaining locked in a notch 50 of the arm 46 until the shaft 1 is released. In the modified construction shown in Fig. 3, the horizontal shafts 105 carry grooved cams 124 which operate the contact springs 110 through knobs 140 on flexible arms 121 carried by the vertical shafts 107. The arms 121 are capable of a limited degree of rotation on the shafts 107, so that, as soon as a connexion has been made, the shaft 107 may be released without breaking it, the knob 140 being retained in its operative position by the grooved cam 124.
