To all whom it may concern.-

' ofITexas, have invented a new and useful Telephone-Signal; and I do hereby declare the following to, be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper- This invention relates to certain new-and useful improvements in a switchboard-drop of the visual signal for magneto system at the central office. of atelephone company; and, more particularly, the invention consists" in the provision of a device, as hereinafter described, claimed, and shown in the accompanying drawings, which may be easily adapted in connection with a suitable switch-. boardof a magneto system.

Another ob ect of the in'vention is to provide a device of this character whereby as a telephone call is made the armatureand indicator is locked in the vision of the switchboard operator, andb inserting the plug of the telephone-nun; or which is called into thesoeket of t e device it will absolutely restore the indicator and armature to its normal pgeition entirely by gravitation, thereby ma 'g the device very efficient and springs which become non-serviceable.

The invention, as shown, is adapted for grounded systems; but it is to be distinctly understood that the invention is not to be limited to any particular system, but may rises further objects ements, which will be hereinafter set forth, and the novel. features thereof will be referred to by the appended claims. v

To obtain a full and correct understanding of the details of construction and combina- The invention com tions of features, elements, and advantages, reference is to be had to the hereinafter set forth description, in connection with the accompanying drawings, wherein Figure l is a perspective view of the imshowing in a diaproved switchboard-drop, grammatic way the relative electrical connections of the operative elements. Fig. 2 is a longitudinal sectional view through the sw itchboard-drop with the plug inserted within the socket. Fig. 3 is a diagrammatic view of the electric wiring of the sw itehboard-drop. Fig. 4 is a cross-section on the line 4 4 of Fig. 2, and Fig. 5 is a detail perspective View of the armature and indicator.

call is made and at the same night-bell circuit, as hereinafter described.

The armature is made integral with the weighted indicator+rod 5, having an iridicator-plate 6 ,at one end thereof, which is provided with a suitable telephone-number which designates a telephone to which the switchboard is electrically connected. The indicator-rod is adapted to cooperate with the notch 7 of a vertically-oseillathrg releasing-bar 8, which is mounted upon the core of said magnet, as illustrated in the accompanyin drawings.

The said lower end 9. f the. releasing-bar 8 only lies within the cut-away ortion when thearmature is attracted, hich causes the indicator-rod to be thrown into engagement with the notch 7 of said bar.

There are two metallic strips 14 and 15 provided upon the under side of the base of the device,' said strips one another by suitable'insulating material. Said strips also form an electrical connection when a telephone-number is desired, which causes the armature to be attracted and the longest strip 15 makes an electrical connection with the telephone that is called when the plug 13 is inserted within the socket. 11 and at the same time cutsout the magnet by separating the plane-surface of the strip 15 from the contact-ppint 16 of the strip 14, as clearly shown in t e drawings.

The operation of the device is set forth as follows: As the receiver '17 of the telephone 18 is lifted from the holder at the subscriberls,

being insulated from v through the wire-connection 22 between said post 21 through thestriphl 5, through the contact-p01nt it, then through-the strip- 14, and
