Title: Improvements in or relating to Alternate Current Motors.
Inventor: FYNN VALERE ALFRED
IPC: H02K27/06
Filed: 1909-12-24
Granted: 1910-08-25
Abstract: 30,208. Fynn, V. A. Dec. 24. Alternating-current commutator machines. - To improve the starting-torque and efficiency of singlephase commutator motors, the induced members of which are provided in addition to the commutator winding with a permanently closed winding, the commutator winding is short-circuited by means of brushes along an axis approximately coinciding with that of the main inducing-winding; and the short-circuited winding either has a high resistance or is separated from the commutator winding by a magnetic bridge or shunt. In one modification, Fig. 2, the induced member is provided with a squirrel-cage 13 and a commutator winding 14 provided with short-circuited brushes 17, the main brushes 15 being connected either in series or in parallel with the inducing winding 12 either directly or through a transformer, or these brushes may be short circuited. When the motor is up to speed, a compensating voltage derived from a stator winding 24 may be applied to the brushes 15. The starting performance may be further improved by providing a magnetic bridge or shunt between the windings 13, 14 ; for example, the commutator winding may be placed in open slots 2, Fig. 6, while the winding 13 is disposed in slots 3 embedded in the laminae so that the fields due to the windings 12, 14, Fig. 2, do not link completely with the winding 13. To overcome the increased selfinduction of the winding 13 under running conditions, the rotor may be built up of thick laminae so that eddy or screening currents are set up in the shunt when flux tends to thread it ; or the material forming the shunt may be laminated either radially or tangentially in a direction parallel to the rotor axis ; or it may be made of solid steel or iron. Both windings 13, 14 may be placed in the same or different slots at the rotor periphery, thick magnetic strips 38, Fig. 7, being disposed above the bars 13, and, if desired, electrically connected to the latter. As shown in Fig. 11, the shunts may be surrounded by a screening-circuit 4 of conducting material, which may be left open at starting and afterwards closed by means of switches 6 ; or, a conducting strip 4 lying in each slot 2 may be connected to the ends of a squirrel-cage bar lying in the nearest slot 3, Fig. 10. The screening circuits may be formed by connecting-up bars situated in the slots 2, 3 to form a closed Gramme-ring winding, three or more points of which may be short-circuited through adjustable resistances &c. by means of slip rings and brushes. Fig. 5 shows a brush arrangement which allows of starting in one or the other direction by closing pairs of switches 29, 31 or 30, 32, the winding 24 supplying the compensating-voltage being either kept in circuit or cut out by means of a switch 33.

Granted: 1910-06-16
Abstract: 7038. Doumet de Siblas, Edmond Marie, Marquis, and Cottray, L. A. March 21. Variable-speed and reversing gearing.-In variable-speed epicyclic gearing, a ring is employed having internal and external sets of teeth respectively engaged by planet pinions carried by disks which can be alternatively held against rotation to put into operation different trains of gearing driving in the same direction. This ring g, which is secured to the driven shaft b, meshes internally with a pinion d carried by a disk e, and meshes externally with a pinion j carried by a disk k. The pinion d meshes also with a central pinion c secured to the driving-shaft a. The pinion j meshes also with an internally-toothed ring i secured to the disk e. When a brake n is applied to a drum l fastened to the disk e, the pinion d rotates about a fixed centre, and the ring g is driven at reduced speed oppositely to the shaft a. When a brake o is applied to a drum m fastened to the disk k, both the pinions d, j become operative, and the ring g is driven at further reduced speed in the same direction as before. Reversed driving is effected by locking all the parts together by a clutch 3. The pinion d is in this case prevented from rotating idly by a companion gear t meshing with a gear u secured to the clutch 3.

Title: Improvements in Filling Thread Cutting Mechanism for Weft Replenishing Looms.
Inventor: HOLLINGWORTH EDWARD
IPC: D03D49/70
Filed: 1911-02-13
Granted: 1912-01-11
Abstract: 3572. Hollingworth, E., [Crompton & Knowles Loom Works]. Feb. 13. Weft, cutting. - When the weft is substantially exhausted and the replenishing- mechanism is actuated, the shuttle feeler 24, Fig. 2, provided with a projection 44, is lowered by a connexion 25, so that, when the lay moves forwards, the projection 44 engages an arm 43 and rocks a shaft 34 carried in bearings in a bracket 33 on the lay. An arm 35, Figs. 2 and 6, which is provided with a stud 36 carrying a plate 37 is thus rocked, and a pusher-blade 39, a cutter-blade 38, and a blade 40 riveted to the plate 37 are moved forwards, the cutter-blade being slotted to receive a guiding-pin 41 on a grate bar 42. The cutter-blade 38 co-operates to cut the thread with a cutter-blade 30 on a spring-controlled bar 26 carried on brackets 16<1>, 16<2> on the breast beam, while the pusherblade 39 inserts the cut end between the head portion 26<4> of the bar 26 and a spring blade 31 covered with leather or felt, whereby the weft end is clamped. The blade 40 acts on an extra prong at the extreme edge of the weft fork and outside the weft grating 18, thus tilting the weft fork and preventing the loom from being stopped. The bar 26 is normally locked in the position shown by a spring-controlled wedgeended pin 28 engaging a groove in the bar, but if the shuttle should accidentally engage the bar 26, the locking-device yields and allows the bar 26 to be moved against the action of a spring 27. Instead of the shuttle feeler, some other part of the transferrer mechanism may be used to operate the cutting-mechanism. In a modification, a cutter 47, Fig. 9, co-operates with a cutter 46 on a bar 26<a>, which has a recess 26<a1> to receive the weft end before it is cut, the weft end being clamped between the spring blade 48 and the bar 26<a>.
