G. STEPHENS. CONNECTION PoR ARMATURE GoNDUcToRs.

F-Isl- UNITED STATES PATENT OFFICE.
GEORGE STEPHENS, OF LYNN, MASSACHUSETTS, ASSIGNOR TO TIIE THOMSON- HOUSTON ELECTRIC COMPANY, OF CONNECTICUT.
CONNECTION FOR ARMATURE-CONDUOTORS.
SPECIFICATION forming part of Letters Patent No. 470,217, dated March 8, 1892.
Application led November 13, 1891. Serial No. l111,792. (No model.)
for making connections from the armature-l conductors tothe commutator-segments. Such connections have been made by supplementary strips connected at one end to the armature-conductors and at the other end'to the segments. The separate strip is made flexible for convenience and for diminishing the strains and liability to breakage.
My invention consists in means for attaching the strip to the conductors and segments without the use of solder, while insuring permanent and reliable connection.
- In the accompanying drawings, Figure l is an axial section of a part of an armature, showing my improved connectors. Figs. 2 and 3 are detail views of the armature-conductor connection. Figs. 4, 5, and 6 show modifications thereof. Figs. 7 and 8 are detail views of the segment connection.
The armature-Wire A, having been wound around core B, has its insulation removed for a portion of its length. nection-strip C is likewise bared and placed against the armature-conductor, so as to bring the bared portions in contact. A strip or band D is then placed over the two conductors and the whole clamped against a resisting abutment, which may be the armaturewinding itself. By this means a length of contact may be secured equal to the length of the armature-core, the armature-conductor being bared for a single length along the core. The stranded conductor is thus made to surround and effectually contact with the armature-conductor.
The armature-conductor may be continuons, as indicated in Fig. 6, and be bared at successive points corresponding to the last turn of each section where connections from the commutator are to be made. In case the armature-coil sections are separate the ad- 'jacent ends of adjoining segments are bai-ed The end of the con-` and placed together and the commutator connection applied, as before. (See Figs. 3 and 4t.)
Figs. 2 and 3 show the preferred form of the connection, it being preferably used with a slotted or toothed armature. The coil-sections A having been wound up, their ends are bared, as above described. The iiexible commutator connection C, having a number of strands of comparatively fine Wire, has its 6o bared end placed against the bare portions of the armature-conductor. The stri pD is Wound over them all, forming a sleeve, as in Fig. 3, and an insulating plate or follower having been placed over the coil-section the sleeve with its contained terminals is placed thereon and a wedge or plug E is driven in over the sleeve, firmly clamping the same against the follower. The upper end of the slot is made tapering, so as to hold the plug in place. 7o Another follower F, preferably of insulation, may be placed between the plug and the oombined terminals, as shown in Fig. 5, Kto prevent displacement or tearing of the latter when the plug is driven in. The strip D is preferably wound around in aspiral form, as shown' in Fig. 3.
At the commutator end of the connectingstrip I employ the connection shown in Figs.
1, 7, and 8, the bared end of the stranded So connecting conductor being inserted in a sleeve or socket G, through which passes a screw H, tapped into the commutator-segment and having a square head 7L, against which a portion of the socket or sleeve Gis struck up, as shown at t', to hold the screw from working out.
IVhat I claim as new, and desire to secure by Letters Patent, is-
l. The combination of the bared portions 9o of the armature-conductor and connectingconductor, the sleeve around the same, and a clamp supported by the armature and clamping said sleeve.
2. The combination of the bared portions of the armature-conductor and connectingconductor, the metal sleeve around the same, and a clamp holding said sleeve against a portion of the armature.
The combination of the armature-coil Io'o section, the bared portions of the armaturecondnctor and the connecting-conductor, the
' having a tapering slot, the coil-section wound therein, the follower placed on saidcoil-section, thel connecting-conductor, the metal l sleeve containing bared portions of the arma no ture and connecting conductors and placed on the followenand a. plug driven into the tapering slot over the sleeve.
5. The combination, with the armature-conductor and the. stranded ilexible'conductor 15 having their ends bard, ot' the sleeve snr-` rounding both of such conductors and clamping the strands against and around the armature-conductor. 6. The connector for attaching armature connections to commutator-segments, consisting in a screw tapped into the segment and a metal sleeve on the armature connection held under the head of the screw and having a. struck-up portion engaging with such head. In witness whereof I have hereunto set my hand this 10th day of November, 1891.
