REGULATOR FOR DYNAMO-ELECTRlC MACHINES.
i SPECIFICATION forming part of Letters Patent No. 264,666, dated September 19, 1882 (N0 model.)
To all whom it may concern Be it known that I, THOMAS A. EDISON, of h'lenlo Park, in the county of Middlesex'and State of New Jersey, have invented a new and useful Improvement in the Regulation of Dynamo or Magneto Electric Machines, (Case No. 415 and I do hereby declare that the following is a full and exact description ofthe same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.
The object of my invention is to produce an automatic rcgulatin g apparatus for dynamo and magneto electric machines which shall act on variations in the number of translating devices in circuit from the machine,or in the speed of the engine driving saidmachine, to adjust the speed of rotation of the armature to the point necessary to produce the generation of current required. This I do by connecting the pulley over which the belt from the engine is placed to the armatureshaft through afriction clutch the latter being adjustable by means of an electro-magnet energized by the current generated, so as to convey more or less power to the armature-shaft, according to the current required.
A convenient form of my invention is shown in the tlrawi11g,whicl1 is a view of aregulating apparatus in elevation, with the friction-clutch shown in section and the circuits in diagram.
A is the armatureshaft ot'a dynamo or magneto electric machine, and B the commutatorcylinder mounted thereon, the armature being omitted for convenience in drawing. 1 2 are the main conductors leading from the commutator, and having translating devices a re placed in multiple are upon them.
(1 is an electro-magnet, so mounted near the end of the armature-shaft A as to revolve therewith. The conductor 2 is broken and formed into contactsprings b b,which bear on the metal collars 0 0, these being insulated from the shaft A. From these metalcollars acircuit, 3 4, runs, which includes the magnet O, the latter being thus placed directly in the main circuit 1 2. A sleeve, cl, is keyed also to the armature-shaft, so that it revolves with it, but has a longitudinal movement upon it, on which sleeve are mounted the armature D of the magnet G and the friction-clutch E. A spring, F, is secured to the sleeve d, so that such sleeve is retracted from the magnet by the spring. The frictionclutch consists of arms carrying friction-shoes e e and united by a toggle or elbowjoint,f.
G is the pulley over which the belt from the engine which drives the armature passes. The pulley G is sleeved to the shaft A so as to turn loosely upon it, and motion is therefore coinmnnicated from the belt to the shaft only through the friction-clutch, more or less power being communicated, according to the position of the friction-shoes within the pulley G.
The operation of this apparatus is as follows: When more translating devices a a are placed in circuit the increased current in the main line causes an increase in the energy of the magnet O, which attracts its armature D, and thus throws the friction-shoes e 6 into greater coir tact with the pulley G, thereby conveying more power from the engine to the armature-shaft and causing the latter to revolve with greater rapidity, thus increasing the generation of current to the desired degree. A decrease in the number of translating devices in circuit causes a decrease in the energy of the magnet O, the spring F throws the armature back, and the friction-shoes e e are partly removed from contact with thepulley. Shouldasudden increase occur from any cause in the speed of the engine which drives the armature-an increase too great to be taken up immediately by the governor of the engine-the friction-shoes e 0 will slip on the surface of thepulley,andtheincrease will not be communicated to the armature-shaft. It is evident that other forms of friction clutch might be used, though that shown isfound most convenientfor the purpose.
The magnet 0 might be placed in a shunt from the main line, insteadof directly therein, with the same effect.
What I claim as my invention is-- 1. In a dynamo or magneto electric machine, the combination, with the armature-shaft and a loose pulley mounted thereon, of a frictionclutch for conveying motion from said pulley to said shaft, and means actuated by the current generated for moving such friction-clutch so as to vary its contact with the pulley, substantial] y as set forth.
2. In a dynamo or magneto electric machine, keyed to said shaft and carrying the armature the combination, with the armature-shaft and of said electro-magnet, and the friction-clutch a loose pulley mountedthereon, of africtionmaking frictional eontact'with the inside of clutch for conveying motion from said pulley said pulley, substantially as set forth.
