J. TAYLOR. TELEPHONE SWITGHBOARD PLUGl Patented May 17, 1898.
Ni'rnn STATES 'Prion'.
PATENT TELEPHONE-SWITCHBOARD PLUG.
SPECIFICATION forming part of Letters Patent No. 604,094, dated May 17, 1898. Application led November 21, 1896. Serial No. 613,021. (No model.)
.To all whom it may concern.-
Be it known that I, J AMES TAYLOR, a subject of the Queen of England, residing at Heatherclifte Helsby, England, have invented certain new and useful Improvements in Telephone-Switchboard Plugs, of which the following is a specification.
As at present constructed triple-contact telephone-plugs are not easy to repair or readjust. The present invention comprises improvements in the construction of such plugs, in part applicable to double-contact plugs, these improvements rendering it possible for a plug to be readily taken to pieces for repairs and readjustment and to be tted together again with facility. This arrangement'. is brought about by the employment of a single central bolt, which, with the aid of suitable nuts, binds together all the respective parts of the stem and interior, so that the loosening of the nuts on this bolt enables the plug to be taken entirely to pieces.
In the accompanying drawings, Figure l shows an elevation of the complete plug, the casing or cover being shown in section. Fig. 2 is a central longitudinal section through a complete plug on a plane at right angles to the view shown in Fig. l. Figs. 3 to 10 show the various parts which constitute the complete plug. A
Like letters indicate like parts throughout the drawings.
On one end of a bolt A and solid with it is formed a plug point or ball A. Over this bolt fits an ebonite tube or sleeve B, one end of which is enlarged to form a washer B', the
outer edge of which is tapered. Over this,
again, iits a metal tube or sleeve O, on one end of which is formed a collar C', while the other end terminates in a tag or tongue O2. An ebonite ring or Washer D is now passed over the tube O and placed next the collar portion C.
` The body of the plug is formed of a metal tube E, one end E of which is smaller than the other. A portion is cut out of the side of the tube E, so as to leave an opening E2. An ebonite tube F, one portion of which is of a size to fit within the part E', while the other portion iits into the main part of the plugbody E, has a small opening F cut in the side of it and a iiat portion F2 out from this opening from the end of the tube. The interior portion is within the narrow portion E. The 1 bolt A, carrying th'e ebonite tube B, metal tube O, and washer D, is then passed into the tube F, the tag C2 being brought out at the opening F', the end of the bolt projecting from the inner end of the tube F. Upon the end of this bolt is placed a smaller nut I-I and a larger nut J, having a iiattened portion J A small screw K, passing through the plugbody E, engages with a slot F3, cut in the tube F, and prevents the latter, and consequently, also, the tube O, from turning. The
end of the tag C2 is tinned or otherwise pre"` pared to be connected wit-h one end of an insulated wire or conductor, the lattened portion J of the nut J being similarly prepared to make contact with a second wire. A third conductor makes electrical contact with the plug-body E by engaging with the screwthreads E3, cut in the end of the latter. An
insulating-casing L is passed over the plug- `body E and there secured to the latter by a screw L.
I claiml. In a telephone-switchboard plug, the combination with a metal bolt A, having the head formed solid with it, of metal tubes O and E, insulatingtubes B and F, insulatingrings D and G, nuts I-I and J, casing L, screws K and L', and `electrical conductors, substantially as described.
2. In a telephone-switchboard plug, the combination of a central metal bolt A having a contact-head, metal tubes O and E, said tube O having a tag C2, insulating-tubes B, F, said tube F having an opening F and a groove F2 to receive the tag, insulating-rings D and G, and nuts H and J, all arranged substantially as described.
3. In a telephone-switchboard plug, the combination with a metal tube C, having a collar and tag, of an insulating-ring D, and tube F fitting over the tube C, the insulat- IOO ing-tube F having an opening through which the tag passes, and a groove Within which it lies.
4. In a telephone switchboard plug, the combination With a metal bolt having a head at one end, an insulating-sleeve thereon and having one end enlarged to form a Washer lying adjacent to the head of the bolt, a metal sleeve on the said insulating-sleeve,said metal sleeve having a collar at one end lying adjacent to the Washer of the insulating-sleeve and having a tongue at the opposite end, an insulating ring or Washer on the metal sleeve adjacent to the collar thereof, a second metal tube forming the body of the plug having one end smaller than the other, a second insulating-sleeve on the second metal tube, one portion of said latter sleeve fitting Within the said smaller portion of the second metal tube, and the other portion fitting in the larger part of the latter tube, an insulating-Washer on the smaller end of the said second insulatingsleeve and a nut on the bolt to secure the various parts thereon, and an insulating-casing ecured to the body of the plug, all as speci- 5. In a telephone -sWitchboard plug, the combination with a metal bolt havingahead at one end, an insulating-sleeve thereon and having one end enlarged to form a Washer lying adjacent to the head of the bolt, ainetal sleeve on the said insulating-sleeve,said metal sleeve having a collar at one end lying adjacent to the Washer of the insulating-sleeve and having a tongue at the opposite end, an insulating ring or Washer on the metal sleeve adjacent to the collar thereof, a second metal tube forming the body of the plug having one end smaller than the other, a second insulating-sleeve on the second metal tube, one portion of said latter sleeve fitting Within the Said smaller portion of the second metal tube, and the other portion tting in the larger part of the latter tube, an insulating-Washer on the smaller end of the said second insulatingsleeve, and a nut on the bolt to secure the various parts thereon, an insulating-casing secured to the body of the plug, a second nut having a flattened portion, and a screw passing through the plug-body and engaging a slot in the said second insulating-tube.
In Witness whereof I have hereto set my hand in the presence of the two subscribing Witnesses.
