Title: Improvements in or relating to Electric Meters, Motors, and Phase Compensations for Electric Currents Influencing them.
Inventor: GUTMANN LUDWIG
Filed: 1901-06-11
Granted: 1901-10-12
Abstract: 11,922. Gutmann, L. June 11. Motors, alternating- current.-A laminated alternating - current electromagnet g i s made to produce two fields in exact quadrature or other desired phase relation to the electric pressure applied to its exciting- coils h, by completing its magnetic circuit through a separate laminated iron part k, which has conducting-plates on its ends, or is surrounded by a metal ring l or by a winding having its circuit closed directly or through a resistance. The winding may be subdivided so that parts can be used, or the resistance may be adjustable. The part k may be supported by a pivot, at one end, and, at the other end, held away from the magnet g by an adjusting-screw. The magnet g and part k may be made multipolar, and the closed electric circuit modified correspondingly, to form part of an induction motor. The construction shown in Fig. 2 is applicable in an induction motor meter having a conductive hollow cylindrical armature a revolving in the magnetic fields. The armature is slotted obliquely except at its ends, and its end distant from the magnet is in the field of main current coils i. The magnet g and part k may be slightly modified in form to give two parallel magnetic fields, through one or both of which a disc armature can revolve. The weight on the lower bearing of the cylindrical armature may be reduced by making its upper end disc of iron, and placing an annular or other electromagnet or permanent magnet above it.

Abstract: 859. Perry, B. F., Perry, F. L., and Perry, A. B. Jan. 13. Machine guns.-The invention is shown as applied to a rifle, but it is stated to be also applicable to machine guns. Fig. 1 shows a vertical section, Fig. 4 a cross-section, and Fig. 8 a detail. The breech mechanism is operated by the wheel 15, which is rotated counter-clockwise by the spring 12. This wheel carries pairs of spring clips 22, which receive the cartridges from the magazine 61, carry them into line with the barrel and support them while they are discharged by the hammer 60. The forward movement of the wheel 15 then causes the clips to be sprung apart by contact with the breech end of the barrel, the clip!! going onwards with the wheel, while the empty cartridge cases fall into the pockets 17 and thence pass by gravity through an opening in the side-plate of the gun. The firing of the gun is effected automatically by the spur-wheel 37, which rotates with the wheel 15, pushing back and then releasing the rod 40, which latter acts on the trigger 50, and this in turn on the hammer 60, which is pivoted at H and is operated by the spring 57. The guide 47 for the rod 40 is provided with a vertical adjustment to enable it to lower the rod 40 clear of the wheel 37 when single shots are to be fired, for which operation the spring pawl 36 is brought into use. The magazine 61 has a vertically-sliding spring door 64 with a lip 67 which is raised and released by the projections 23 on the wheel 15 as they rotate past it, thus causing the cartridges to be fed one by one to the spring clips 22.
