Title: Improvements in Alternate Current Motors.
Inventor: ABLETT CHARLES ANTONY
Filed: 1902-11-28
Granted: 1903-10-01
Abstract: 26,272. Ablett, C. A. Nov. 28. Sparking, preventing. - To prevent sparking at the commutators of alternating-current motors, the self-induction of each coil in the rotor is reduced to a minimum before the circuit is broken at the commutator ; and, to enable the motor both to start and run properly, the self-induction of the coils on the secondary core is varied as desired. These objects are carried out, by way of example, in the motor shown, in which the cast-iron frame C has dovetailed slots to receive projections from the laminations I, which form polar projections p, in which the primary coils c are slid and are held in position by the flux screens h which rest in notches in the projections. These coils are connected to an alternating-current dynamo &c. The rotor S is mounted upon a shaft N, and has a number of coils, such as x, y, z, each of a width approximately equal to that of a polar projection, but less than the distance between any pair of polar projections. As the secondary rotates in the direction shown, the coils alternately pass beneath a pole and a screen. In the latter position, the magnetic flux through them is reduced to a minimum, and consequently also their self-induction. At this point, then, the circuits of the coils are broken without sparking by means of brushes bearing upon the commutator D, to the segments of which the terminals of the secondary coils are connected. When a secondary coil arrives beneath one of the polar extensions, or slightly beyond it, it is again short-circuited. To vary the self-induction of the secondary circuits, their coils extend beyond those of the primary, and the end plate E of the frame has an arm A opposite each polar projection, in each of which arms is a slot r for a guide-piece secured to a U-shaped magnetic mass M, which can be moved inwards or outwards by a non- magnetic ring R caused to slide upon the shaft N by a lever L and links m.

Abstract: 16,911. Foard, C. R. Oct. 9, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Potato planters.-Relates to a machine for planting potatoes and other "sets," which, having one end suspended from the shoulders of the operator and being drawn along and fed by him, automatically drops the potatoes at uniform distances apart. The operator straddles the trough-like frame 1, the strap 5 being passed over his shoulder, and feeds the potatoes from the box 4 to the hopper 3 as he walks along with both hands free. From the hopper 3 the potatoes drop upon an endless travelling sprocket-chain 16, which is provided with equidistant spurs 17. As each spur reaches the discharge spout 22, it strikes a projection on a spring-controlled and hinged side, the lower inclined part of which forms the bottom of the spout, and thus discharges the potato previously dropped therein. The chain 16 is carried on sprocket-wheels 8, 10 on transverse shafts 6, 9, the latter of which is driven by spur gearing from the shaft 12 of a traction wheel 13, which travels along the furrow. Upon the opposite end of the shaft 12 is a smaller loosely-mounted guidewheel 14, which travels on the surface of the ground. In the bottom of the hopper 3 are arranged two horizontal plates 17<a>, Fig. 2, pivoted at points 18 and having their edges shaped to form a depression 19 to receive a potato. Normally the plates are kept closed by springs 21, but, when a spur on the chain strikes the bevelled edges 20, the plates open and drop the potato on to the chain. A portion of the frame is covered to protect the operator's clothing.

Abstract: 28,745. Swinehart, J. A. Dec. 31. Tyres, elastic other than pneumatic; felloes or rims.-Rubber tyres are provided with means for heating the tyre, or a material therein, to alter its consistency and sc facilitate the securing of the tyre in the rim or its removal therefrom. The means can also be used to form a core of sponge rubber, with air cells, inside a tyre. The rubber tyre A has a dovetailed groove 2 round its inner surface, and grooves 3 to take the edges of the flat-bottomed rim. Wires or nails 8 are driven into the tyre at intervals to strengthen it. The groove 2 is filled with a fusible cement or other material which can be softened by heat. The tyre is pressed into the rim while the cement is soft. When the cement hardens, it locks the side portions of the base of the tyre within the rim. To remove the tyre, the cement is heated by passing an electric current through a wire or band 10 in the groove, the terminals 11 of the wire extending through the rim. The wire 10 may be replaced by a tube which is heated by steam or otherwise. Instead of using a material which softens on heating, the groove 2 may contain uncured rubber, rubber cement, or other material, which is hardened by heating, as described above, after the tyre is in place in the rim. A tyre with a large number of air chambers or cells is obtained by heating a wire or tube which is arranged in the tubular tyre and surrounded with uncured sponge rubber.
