COLLECTOR.
SPECIFICATION forming part of Letters Patent No. 394,797, dated December 18, 1888. Application filed September 12, 1888. $crial No. 285,175. 1N0 model.)
To all whom it may concern.
Be itknown that 1, JOHN Tencoxrxc, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Collector-Rings for Alternating-Current Dynamo-Electric Machines, of which the following is a specification.
My invention relates to improvements in the construction of collector-rings for alternating-current dynamo-machines, but more especially to collector-rings :for those types of dynamos which yield heavy currents of comparatively low potential and are used for practicing the art of electric welding, as described in Letters Patent Nos. MEMO, 3%,141, and 2347,18, granted to Elihu Thomson, August 10, 1880.
In apparatus, such as is known as direct electric welding-machines, in which the armature is the revolving portion of the apparatus and the fields are stationary, it is often difficult to collect the large low potential currents from the collector-rings and convey them to the clampin devices which hold the pieces of metal to be operated upon. The potential of such machines being extremely low and the current of such enormous volume, it is important to have a minimum of joints or contacts between the terminals of the armature-windingand the collector-brushes resting on the collector-rings. At the same time such collector-rings must be large enough to carry these heavy currents without dangerous and wasteful heatin It is the object of my invention to provide such collector-rings and to facilitate and cheapen the construction of the same.
My invention consists, briefly, in collectorrin composed of three pieces of metal, which pieces areof peculiar shape and easy construction and form a portion of my invention, as will be hereinafter :fully described.
Referring to the accompanying drawings, Figure 1 is a side view of the revolving armature of a direct-welding machine, sl'iowing my improved collector-rings placed on the shaft of the machine and the connections from the arinat-urewimling to these rings. Fig. 2 is a side sectional view of my invention. Fig. 3 is an end view showing the details of my invention, partly in section.
. they consist.
Referring to Fig. 4', F is a hollow cylinder, forming one of the three pieces of which my improved collector-rings consist.
Atf, Figs. 2 and i is a shoulder. and at f a large flange of sufficient size to carry the heavy welding-currents conveyed to the armature-winding \V. (Shown. in Fig. l.)
The piece F is fitted neatly over a bushing or sleeve, as shown at S in Fig. 2, which sleeve is made to fit firmly to the shaft of the machine, as shown atX in Figs. 1 and 2, and insulating material, lsuch as wood or micais placed between the sleeve S and the piece F to prevent the current from being conveyed to the ground through the revolving shaft of the machine. The collar s, Fig. 2, prevents the sleeve S from passing completely through the cylinder F. After the cylinder F has thus been placed on sleeve S the piece F, 2 and l, is placed in position, as shown in the figures, and swured by the nut c. Insu lating material, 1', Fig. l, is placed between the cylinder F and the piece F, so that there will be no shortcircuiting of the dynamo by the passage of the currents from the cylinder F to the piece F. The apparatus is now ready for the last piece, R, Fig. r, to be put in position. It is done by placing it on the side of the cylinder F which carries the flange f and screwing it to the piece F, through the holes N N, as shown in the figures. This piece is also insulated from cylinder F. The complete apparatus is shown in a side view in Fig. l and end view, Fig. I. It will be seen that the cylim'lm' F thus forms the collectorring and the two pieces F and R form the other collector-ring, the two rings being insulated from each other, as described above.
It is obvious that the pieces F and R must be composed of material which will readily conduct the heavy currents, and of a size which will carry such currents without dangerous and wasteful heating.
It is also obvious that the shoulder F, Fig. 9, could be omitted, or could even be turned about, making the ring of the same diameter as ring C, Fig. 1. I have found it more convenient to consi ruct my collector-rings as Fig. lis a perspecabove described.
The terminals of the armature-winding IV, Fig. 1, are flXed to the flanges f and f in the following manner: Holes h h h are bored in the flanges f and f, as shown in Fig. 3, as many holes as may be necessary to hold the wires IV. (Shown in Fig. 1.) The wires are then placed in the holes and soldered firmly in, thus making a solid connection with flanges f and f, and thus with the collectorrings C and C, Fig. 1.
What I claim is 1. In collector-rings for dynamo-electric machines, conducting plates or flanges for the attaclnnent of the terminals of the armature coil or coils, an integral connection between one of such plates or flanges and the adjacent collecting-ring, and a connection from the other such plate or flange extending to the second ring through a space or compartment made in the first ring.
2. In a dynamo-electric machine, separable collector-rings made of three metal conducting-pieces, viz a complete ring with a conducting-extension terminating in an expanded piece or flange for the attachment of the armature coil or coils terminal or terminals, an incomplete ring carrying the flange or eX- panded piece for the attachment of the terminals of the other coil or coils, and a segment of the latter ring for fitting into and completing such ring when the parts are put together, substantially as shown.
In testimony whereof I have hereunto set my hand this 10th day of September, A. D. 1888.
