| Description: |  | Abstract:
 My invention has for its object to provide a practical and inexpensive pull-socket for incandescent lamps. With this end in view I have devised the simple and novel construction of which the following description, in connection with the accompanying drawings, is a specification, numbers being used to designate the several parts.
Claim:
In a device of the character described the combination with an insulating-block having inclines, one of said inclines being provided with a plate which is electrically connected with one of the binding-screws, of a rotatable contact-plate electrically connected with the other binding-screw and having downwardly-extending arms which are adapted to engage the inclines and plate,  a rotatable operating-plate which is adapted to engage the contact-plate each time it is actuated to move the contact-plate forward and place one of the arms either in contact or out of contact with plate and a spring acting to retain the operating-plate and the contact-plate in operative position and to return the operating-plate to its normal position after each actuation. |  |
