SPECIFICATION forming part of Letters Patent No. 383,832, dated May 29, 1888.
Serial No. 248,455. (No model.)
To aZZ whom it may concern:
Be it known that 1, WILLIAM STANLEY, J r. acitizen of the United States, residing-in Great Barrington, in the county of Berkshire and State of ltlassachusctis, have invented certain new and useful improvements in Current-Collectors for Electric Machines, of which the fol lowing is a specification.
The invention relates to the construction of coinmutators or collectors for electric niachines, and is designed especially for alternatocurront machines.
In carrying out the invention two coutinuous rings of metal are formed with outer bearing-surfaces for receiving the contact or collecting brushes, and these are mounted and insulated in the following manner: Between the two rings is placed an annular washer of non-conducting material, within which passes a cylinder or spool oi'siniilarmaterial. Insulated bolts extend through both rings and the washer, binding the parts together. At the ends are placed other insulating-rings. For the purpose of obtaining electrical connections with the respective rings bolts extend from one end of the commutator into the res ective rings, the one passing to the farther ring insulated or separated from the nearer ring. The connections are then made with the heads of these bolts.
The invention will be more particularly described in connection with the accompanying drawings, in which- Figure 1 is a transverse section of the cow niutator, and Fig. is an end view.
Referring to the figures, A represents the armatureshaft of an electric machine, and 1 0 the respective commutator rings. These are of n1etal-such, for instance, as brassand are preferably constructed with projecting flanges c c at their edges, and between these flanges it designed that the brushes shall rest. The rings are separated from each other by a washer, B, of vulcanized fiber or other suitable insulating material. The rings are insulated from the shaft by a spool, B, of insulating material. Against the respective ends of the commutator are placed insulatingrings Z) 6*. The spool 13 is preferably providcd at one end with a flange, I), which projects oi'itward over the inner edge of the ring I)". The entire device is held together by bolts 6 6 extending through both rings 0 and 0, but insulated therefrom.
Electrical connections are formed in the following manner: A bolt f, is screwed through the plate 0 into the ring 0. A block, F, of non-conducting inateriahis then placed over the head of the boltf, a suitable opening being left in the block for this purpose. A screw-threaded hole is then cut or drilledinto the head of the boltf at right angles to its length through an opening left in the block F, as shown, and through this there is passed a second belt, h. This serves to continue the electrical connections of the bolt 7', and at the same time to prevent the latter from being loosened by the operation of the machine. A binding-screw, 1 9 may be set into the head of the screw h, for the purpose of securing an electrical conductor, L. In like manner a bolt, f extends through a suitable opening in the ring 0 and screws into the ring 0, forming electrical connection therewith. The head of this bolt is set into a block, F, and connections are made therewith bolt, 79, and bindin screw If, receivingthe conductor I as described with reference to the bolt f. The entire structure is thus compact and solid and the electrical connections with the respective rings are such that the parts cannot easily get out of order.
I claim as my invention 1. The combination of the rings C and C the bolts f and f, terminating in the respective rings, the blocks F and F receiving the heads oi the respective bolts, and the bolts k and Frientering the heads of the bolisf andf 2. The combination of the rings C and C the bolts f and f terniinatingin the respective rings, the blocks F and F", receiving the heads of the respective bolts, the bolts h and Ir, entering the heads of the bolts f and f, and the binding-screws 1: and for securing electrical connections with the respective rings.
3. A collector for electric machines, consisting of two rings of conducting material placed side by side and insulated from each other, two conductors for forming electrical connections with the respective rings, one of said conductors extending into one of the rings and the other extending through that ringinto scribed my name this 19th day of August, A. the second ring, but insulated from the first- D. 1887.
