HENRY M. CRANE, OF NEW YORKJN. Y., ASSIGNOR TO WESTERY ELECTRIC COMPANY, OF CHICAGO, ILLINOIS,- A CORPORATION OF ILLINOIS.
ELECTROMAGNETIC SIGNAL-CONTROLLING 'nnvrcn.
Application filed January 29, 1906. Serial No. 298,317.
Specification of Letters Patent.
Patented June 9, 1908.
To all whom it may concern:
Be it known that I, HENRY M. CRANE, citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Electromagnetic Signal-( ontrolling Devices, of which the fol-- lowing is a full, clear, concise, and. exact description.
My invention relates to an electromagnetic signal controlling device, and has for its object to provide an improved, simplified and eilicicnt magnetic controller adapted to eil'cct the sequential operation of electrical devices or mechanisms.
The device of my invention is capable of specially advantageous use in connection with telephone exchange service, being adapted for use as a combined line and cutoil relay.
Generally speaking, iny invention. contemplates a magnetic controlling device comprising an electromagnct provided with two armatures, one of which is adapted when attracted to'opcratc a contact device and close a gap iii the magnetic circuit of said magnet, said armature being responsive to current in said magnet. ed to respond upon the closure of said magnetic gap by said first-mentioned armature to an increase of current through said magnet, and is arranged when attracted, to operate contact devices associated therewith. With my device, therefore,employing but a single magnet, a sequential operation of circuit controlling devices may be obtained.
I will describe my invention by reference to the accompanying drawing, wherein,
Figure lis a side elevation of' an electromagnetic signal controlling device embodying my invention; Fig. 2 is an end vi w thereof; Fig. 3 is a plan view; Fig. 4 is a longitudinal sectional view on line 4--4 of Fig. 3; and F 5 is a detail view of the end. of the magnet, with the armature removed, showing the contact made thereby.
The same letters of reference are used to designate the same parts where ver shown.
Referring now to the drawing, which shows the preferred form of my invention, the mag net a. of the controlling device is provided The other armature is adapt with a core a surrounded by a pair of mag net windings or helices a a A light armature 7), preferably L-shaped', is mounted adjacent to oneend a of the magnet core, and adapted when a tracted to engage said core and thereby close, a gap in' the magnetic circuit of the magnet a, Said armature is arranged to be respqnsive to current in one of the windings a and controls a pair of contacts c c, which may serve, when my device is used in telephone exchange work, as the line relay contacts.
. An armature d is provided for the magnet, preferably movably secured to an L-shaped extension e of the enddz of core a, so as to lie )arallel to the magnet spool, with its free en extending adjacent to one arm I) of armature b, said arm preferably lying above the armature d and in a proximately the same plane therewith T e armature d is preferably connected to the extension (2 by means of a flexible member 7L, said member serving to permit the movement of the armature (Z. The armature d also controls a gap in the magnetic circuit of said'magnet, and
is adapted to respond when the magnetic gap controlled. by armature b is closed, to current flowing in order of said windings (1 The armature (Z when attracted engages the arm I) of armaturc'b, closing the magnetic gap controlledthereby and completing the magnetic circuit'ofsaid magnet. The armature (Z is thus primarily under the control of armature a, and after the armature b has acted to close the gap, the control of armature (Z is transferred to its magnet winding, which upon receiving current, increases the magnetic iluX to eliect the operation of said armature. It will be noted that the arma tures l) d are serially included in the magnetic circuit of the electroinagnet, each of said armaturcs forming a return pole piece or the other.
The armature d is adapted in its movement to operate contact devices which in the present instance conrprisc three contact springs and. their anvils, mounted upon but insulated from the corccxtcnsion c, the armature preferably carrying pins g adapted upon the movement of said armature to engage sand separate said springs from their anvils These contact springs in telephone service might control the line and line signal circuits, in the manner of the well known cut-cit relay.
