Title: Improvements in Spinning Machines for Artificial Threads.
IPC: D01D7/00
Filed: 1911-02-17
Granted: 1912-02-19
Abstract: 4078. M³ller, O., and Franke Geb. Feb. 17. Winding - machines; driving - arrangements.-The reciprocating guide-eye, through which the bundle of twisted or untwisted artificial threads passes when winding, is actuated by a cam shaped to render the motion of the guide-eye quicker at the ends than at the middle of its path. The resulting spool is bulged at the middle, and the threads are wound thereon in such a manner that every point of them can be reached by the liquid with which they are subsequently treated. In Figs. 1 and 2, the rotating shaft o is shown provided with a spur-wheel r, which gears with a second spur-wheel r<1> carried on a shaft o<1>, also carrying the cam, which rotates between two rollers s<1>, s<2> mounted on the bar l. This bar moves longitudinally on antifriction rollers and carries the guide-eyes m. If the thread bundle is to be twisted prior to winding, it is passed through a tube 8 and an eye 11, the former being rotated through pulleys 9, 15, a belt 16, and a pulley 17 on the shaft o. The Provisional Specification also describes a method of rotating the spools, and a method of removing full bobbins. The main shaft is provided with as many spur - wheels as there are spinning - devices, these wheels gearing with spur-wheels mounted on carriers for the bobbin spindles. Recesses are provided in the bobbincarriers into which pawls may be dropped in order to lock the carriers when a bobbin is being wound. The spindles are connected to the bobbin carriers by bolts so that they can rotate in slots in the carriers. The thickened portions of the spindles through which the bolts pass are formed with bevelled faces against which a spring presses. The spool can thus be held in a position parallel to the main shaft, and also in an inclined position to enable a full bobbin to be removed.

Title: Improvements in and relating to Single-phase Commutator Motors.
IPC: H02K27/08
Filed: 1911-09-20
Granted: 1912-02-15
Abstract: 20,829. British Thomson-Houston Co., [Allgemeine Elektricitats-Ges.]. Sept. 20. Alternating-current commutator machines.- In a single-phase commutator motor in which the rotor gives the field excitation at one period and the stator at another, the change from one method of excitation to the other is effected by shifting the brushes. A divided stator winding s, s' is connected through movable brushes b, b<1> and fixed brushes a, a<1> to the two secondary windings t, t' of a transformer T. The stator windings s are arranged at right-angles to the fixed brushes a, a'. The quadrants a, band a', b<1> of the armature carry current, and the other two quadrants no current, so that as the brushes b, b<1> are shifted into the position shown in Fig. 2 the number of armature conductors carrying current is increased. In Fig. 1 the vertical axis forms the working axis and the horizontal axis the axis of excitation; in Fig. 2 the opposite is the case. With the brushes b, b<1> in the position shown in Fig. 2, short-circuited or series compensating-windings c, c<1> are employed. The compensating-winding may be left in circuit at starting, Fig. 1, and its effect unweakened, or weakened by closing the winding through a resistance instead of short-circuiting it, or in the case of series connexion by reducing the number of windings. In the vertical axis, the armature may be completely or more or less over-compensated or under-compensated by the stator winding s, s<1>. The direction of rotation is reversed by reversing the connexions of the fixed brushes a, a<1> or of the stator winding s, s<1> and movable brushes b, b<1> and shifting the latter in the reverse direction. The reversing switch and the device for shifting the brushes may be interlocked. The switching- device for the compensating- winding may also be interlocked with the brushshifting device. Where the compensating-winding is used in starting, it may have fewer turns than the armature and be connected in series with the fixed brushes at starting and be shortcircuited when a high speed is attained.

Granted: 1912-10-03
Abstract: 23,931. Dow, J. S. Oct. 28. Comparison photometers comprising one or more pairs of incandescent electric lamps connected in parallel, one lamp of each pair having a metallic filament, with a partly reflecting and partly translucent screen, is used for indicating variations in voltage, or as a reference standard for checking photometers. In the arrangement shown in Figs. 3 and 4, the lamps C, M are contained in a box with an accumulator A, a resistance R, a switch, and a screen P. The metal lamp M, which is fixed in front of a glass disk D, is first compared with a standard light, and the pressure is varied by means of the resistance to give a definite candle-power. The carbon lamp C is adjusted in position to balance the metal lamp, and is then clamped. Subsequent variations in pressure alter the candlepower of the lamp, and the resistance is adjusted to restore the balance. The screen consists of a matte opal glass O<1>, in front of which is placed a mirrored glass O<3>, part of the mirror-surface of which has been removed to leave three or more slots, or a continuous band. A second opal glass O<2> is illuminated by the metal lamp, and the reflection of this with the light from the screen O<2> is viewed through an aperture a. The carbon lamp may be arranged so that one of the slots is darker and the other lighter than the central slot. A coloured glass may be inserted in the aperture. The parts of the screen may be adjustable. The box also contains a white celluloid screen mounted in a stand V in the base of which is a tape measure V which may be attached to a catch W for checking the secondary standards of photometers, a mark on the box indicating the centre of the metal lamp.

Abstract: 24,653. Boult, A. J., [Canfield, R. A.]. Nov. 6. Punching; punches; embossing; angular bending; bending-formers; cupping.-Stoppers of the form shown in Fig. 63 are formed by punching- out a blank 29, Fig. 12, from a strip, and embossing and punching to the form shown in Fig. 40; the blank is then folded over, cupped, and provided with a cork disk, to which it is clenched. The machine has a reciprocating carrier-slide B, Fig. 12, over the lower die plate, for transferring the blanks from one die to the next; it has holes 22<a>, which register with a hole 22<b> in the base of the machine when the slide is in extreme positions, a cam-operated locking-bolt registering the holes. The various upper dies are carried by cam-operated slides and the lower dies are lifted through springs by cam-operated plungers to return the blanks to the carrier after the various operations; the machine is driven by a clutch, the bolt of which is withdrawn when the operator releases a treadle. The strip 28 is fed against a gauging stop 145, which is lifted periodically to allow the strip to pass under it. The folding- mechanism, Fig. 50, comprises a cam-operated nosed lever 77 which coacts with an anvil or mandrel 73, Figs. 50 and 51, which swings horizontally and is moved into and out of operative position by the reciprocation of the carrier B, Fig. 12. The lever 77 moves upward and bends the projecting portion 29 of the blank up at right-angles; as a projection 79 on the lever meets an abutment 80, the lever turns about its pivot and the nose completes the folding. The folded blanks are next cupped by dies 92, 99, Fig. 58. The cork disks are fed in by a centrifugal feed-device G and the folded and cupped blanks are clinched by dies into the disks, the completed stoppers being knocked out from the carrier into a discharge shoot.

Abstract: 25,919. Rees, H. J., and Metals Extraction Corporation. Nov. 20. Zinc, copper, and other sulphites and sulphates; zinc oxide.-Zinc, copper and other sulphates and sulphites, particularly the zinc salts, are obtained from leaching-solutions that are repeatedly used, by treating the solution as described in Specification 7222/11 and then splitting-off a part of the solution, which part is then treated for the recovery of the remaining salts while the rest of the solution, after making up its bulk with water, is used again in the circuit. The solution containing zinc sulphate and sulphite such as that obtained by leaching an ore with sulphurous-acid solution is treated in the tower as described in the beforementioned Specification to precipitate zinc sulphite and some sulphate, and a part of the solution is then split off and evaporated to dryness, the bulk of the remainder being made up with water for use again. This prevents the accumulation of zinc sulphate in the leaching- solution. The zinc sulphate may be calcined for the production of zinc oxide.

Abstract: 3874. Eckschlager, H., and Eckschlager, E. Feb. 16. Optical-projection apparatus.- Pictures, photographs, placards, &c. are suspended in horizontal or vertical guideways in a manner which enables them to be moved along intermittently. The immediate operating - means consists of reciprocating sliders. Worm gearing 9, 11 and bevel gearing drive disks 14 with studs 15, which reciprocate vertical slotted arms and attached slides 20 provided with catches 21. These move the pictures &c. from one end of a guideway to the middle and then on to the other end.. The groups of pictures &c. accumulated in the side guideways are moved by the thickness of a bearing by a projecting arm 38 whenever the shafts 31, 32 rotate and actuate the sliders 37 agaist the influence of their springs 39. The catches 21 are made to yield somewhat by being held in slots under the influence of a spring 24. A central illuminating-lantern with dimmed faces may illuminate the device. In apparatus with vertical guideways, sliders for moving the pictures are also used; but the pictures rest upon sets of bolts, Fig. 12, urged into the guideways by springs. Rotating cranks 55 reciprocate the sliders 61, each carrying a pair of spring-controlled bolts. The supporting-bolts on one side are forced back, and the pictures are lifted from the middle of the frame to the upper magazine, and from the lower magazine to the middle bolt respectively; while on the other side of the frame the sliding carrier pushes back specially controlled bolts in its upward journey and takes the pictures and lowers them to the central supporting-bolt and the lower magazine respectively. As the sliders approach the end of their travel they actuate spring-controlled levers 75 and cause a reciprocation of a slider to move a series of pictures by the thickness of a picture support along the magazines. To prevent the pictures from being pressed together when the actuation of the lever 75, Fig. 11, is too great, a sliding piece at the end of the lever is then removed out of contact with the projection 90 on the actuating-slider when a roller 88 engages a plane 89. The sliding pieces for moving the pictures may be actuated by chain gearing with projections on the chains. The pictures may be moved in connexion with an optical-projection apparatus.
