/b (LN, whom, t may 00p/cern:
Be it known that we, OWEN M. GALLowAY, EDWARD B. WHITE, and ADAM D. NEPTUNE, citizens of theUnitedStates,residing at Mountayr, in the county of Ringgold and State of Iowa, have invented certain new and useful Improvements in Telephone Out-Outs and Switches; and we do declare the following to be a full, clear, and exact description of the inro vention, such as will enable others skilled in the art to which it appertains to make and use the same.
Ourinvention is an improved telephone cutout and switch for use on a private telephoneline or in connection with two of such lines;
and it consists in the construction, combination, and arrangement of devices hereinafter described and claimed.
In the accompanying drawings, Figure 1 is 2o a front or outside elevation of a telephone cutout embodying our invention. Eig. 2 is a side elevation of the same; and Fig. 8 is a sectional view of the same, taken on the plane indicated by the line x of Fig. 1. Eig. 4 is a detail 2 5 sectional View taken -on the plane indicated by the line g/ 1/ of Fig. 1.
On the base 1 is a conducting-strip 2, having a binding-post 8 at its lower end for the attachment of an instrument-wire a. To the 3o other end of the conducting-strip is connected a switch-arm L1, which has an operating pivotrod 5 of sufcient length to extend through a wall of a building and at the inner end oi' which operating-rod there is a button 6, by
3 5 means ofwhich said rod, and hence, also, the
switch-arm, may be turned. The base is designed to be secured to the outer side of a building, andthe switch-arm is designed to be operated from the inner side of the building by turning the said button.
On the outer side of the base and on opposite sides of the conducting-strip 2 are binders 7 8, which are provided, respectively, with contacts 9110 and with connecting spring-'jaws 11 12. Ground-connectors 18 111, having conducting spring-jaws 15 16, the latter being respectively opposite the jaws 11 12 and appropriately spaced therefrom, are secured on the base. Between the said pairs of jaws 11 15 and 12 16 are pairs of carbon plates 17, between which are secured strips 18 ot perforated mica or other suitable non-conducting material.
A bell-connector 19 for a bell B is secured to the base. On the inner side of the latter is a circuit-closer 20, comprising a contactpiece 21 and a contact-spring 2 2. Said contact-piece is connected by a conducting-wire 23 (indicated by a dotted line in Fig. 1) to thc binder 8, and said contact-spring is connected by a conducting-wire 24 (indicated by a dotted line in Fig. 1) to the binder 19. Said spring is normally in contact with the contact-piece to establish electrical connection between the connector or binder 19 and the binder 8.
On the outer side of the base is a spring 25, here shown as a bowed spring, having longitudinal slots 26 in its ends engaged b v the studs or pins 27, which secure the said spring on the base. From the inner side of the said Spring', at the center thereof, projects a spur 28, which extends through an opening in the base, and when the spring is pressed toward the base engages the contact-spring 22 and moves the free end ot' the latter from the contact-piece 21, thereby breaking electrical connection between the connector or binder 19 and the connector or binder 8. The switcharm may be moved in position to engage and thus depress the spring and it may also be turned into engagement with either of the contacts 9 10.
The instrument is connected to the binder or connector 8. A line c is connected to the binder or connector 7. A line is connected to the binder or connector 8. Each of the binders 13 14: has a ground connection, and the binder 19 is connected to an extension-bell.
In order to talk on line the switch-arm L1 should be turned into contact with the contact-spring 10. To use the line c, the switcharm 4 is turned into contact with the contactspring 9. The instrument may hence be used on either of the lines. To protect the instrument and the bell B from injury by lightning, the switch-arm should be turned into engagement with the spring 25 to break the circuit at 20. A current of high potential over either ot' the lines will be grounded, as will be understood. The bell on the instrument rings when the call comes on the line c, and the bell B or extension-bell rings when the call comes over the line b, so that our improved cut-out and switch enables a single instrument to be used on two lines and also aifords perfect protection to both instrument and bell.
Having thus described our invention, what lOO We claim as new, and desire to secure by Letters Patent, is
l. The combination of line conductors, an instrument-conductor, a switch-arm to which the instrument-conductor is connected, said switch-arm being adapted to include the instrument in circuit With either of the line conductors, a bell-conductor connected to one of the line conductors and including a normally closed make-and-breal, the latter being opened by the switch-arm when said switcharm is out of connection With both of the line conductors.
2. The combination of line-circuits, each having a lightning-arresting ground connection, an instrument-conductor, a switch-arm to which the instrument-conductor is connected, said switch-arm being adapted to include the instrument in circuit With either of the line conductors, a bell-cond uctor connected to one of the line conductors and including' a normally closed malie-and-break, the latter being opened by the switch-arm when said S`\vitch-arm is out of connection with both oi the line conductors.
3. The combination of line conductors, an instrument-conductor', a switch-arm to which the instrument-conductor is connected, said switch-arm being' adapted to include the instrument in circuit with either of the line conductors, a bell-conductor connected to one oil the line conductors and including' a normally closed make-and-break, and a spring having a pin to open-the make-and-break, said spring being operated by the switch-arm when the latter is out of connection with both of the line conductors.
ln testimony whereof We have hereunto set our hands in presence of two subscribingl witmesses.
