Specification of Letters Patent.

I Application filed November 11 1905. Serial No. 286,888.
To all whom it may concern:
Be it known that I, EDWARD E. CLEMENT, a citizen of the United States, residing at lVashington, in the District of Columbia, have invented a certain new and'useful Iniprovement in Senders for Automatic Telephone Systems, of which the following is a specification, reference being .had therein to the accompanying drawing. y Q
My invention relates to lephone systems and especially to the ap 'ratus for signaling the central oflice.
The object of the invention is to provide a sending device by which an unskilled person may signal numbers.
This device may be employed in either semi-automatic or full automatic systems.
It consists essentially of circuit breaking mechanism for transmitting impulsbs, a movable operating member having a single finger hold and adapted to actuate the circuit breaking mechanism, and a fixed limiting member having a plurality of lingerholds spaced apart from each other in the path of movement of the operating member,'all the finger holds being within a single hand span.
In the. drawings Figure l is aface view of the casing ofthe device. Fig. 2 is a longitudinal section thereof. Fig. 8 is an interior ,view of the casing. Fig. 4 shows a simple circuit tobe used in connection with thesender.
Referring to the drawing, 1 represents a casing of suitable material and 2 the cover or door therefor, which forms a support for the mechanism of the sender. Secured to the inside of the door 2, by screws 3, is a frame comprising front and back plates 4 and 5 separated a suitable distance from each other by columns 6.
Journaled centrally on the door 2 in the front and back plates 4 and 5 is an operat-' ing shaft 7 which projects through the door 2, where it is provided with an operating lever 8, which has its end formed with a finger opening 9. Secured to the shaft 7 and to the front plated, seatediri a depression 10 formed in the door 2, is a clock spring 11, which normally holds said lever in vertical position and which returns it to said position after it has been released.
Rigidly keyed to the shaft 7 .is a toothed segment 12, provided with slanting teeth 13 around the outside edge thereof, and-withelaterally projecting stud -14, on which is polarized magnet" 29, hav-in nected to the tip side, and a battery connected to the sleeve side.
A branch circuit normally connected to the spring and sleeve sides of the line b mounted a spring pressed pawl 15 adapted to engage and operate inone directionlof in the plates 4; and 5' and carries and oper- 5 ates a governor. 18 of any preferred Between blocks of insulating material 19- 7 attached to the front plate/i are secured the contact springs 20 and 21, the former of which is bent near its free end at an obtuse,
angle and then bent back so as to normally contact with the spring 20. The spring 21? is provided with a tongue 22 which roj'ects' into the path" of the teeth '13 of t ,mentl2.
Secured to the outside of the door 2 ad-v I jacent the lever 8 is an arc-shaped number plate 23. The foot 24 of the plateis secured to the door and the head 25 is raised therefrom by the web 26. The-edges are punched to form arms 27 having lateral tongues 28,
which are bent to stand vertically and form thumb or finger holds.
.Mounted within the ca sing, at the back thereof, is a signaling device m comprisinga 30 pivoted in the yoke 31, a signal operating rod 32 and. a target 3 L pivoted at'35 tot-he edge of the casing 1. i
its armature In Fig. 4: I have shown a diagram of a circuit adapted to this apparatus, but I do,
not wish to be limited thereto, as this circuit and the signal, device m form no part of the present invention and will not be claimed herein. The circuit shown com= prises two conductors A and B, which are" connected with the subscribers stationX and the central station Y. An operators' cord circuitis represented by I and has the usual plug with tip. D and sleeve 13',"
adapted to contact respectively with the springs D and E of the jack. circuit also has a suitable indicator G con ceiver from the hook K, which closes the circuit ABt- Current travels from battery The cord H, through annunciator coil- C and com ductor d to spring D .of the jack-P- -E,
through conductor A, switch-hook K, through the telephone to the contact springs 2120, to the signal device m and over conductor B, terminal E to conductor 0. and ground, to battery. The operator, noticing the signal, inserts the answering plug of her cord in the jack D-E, which discon nects conductors-Ze, cuts oil eleetromagnet 7C and ,places battery H on the sleeve side of line, consequently reversing current through the magnet 29 and throwing thej jsignal target 34 so that it may be seen by the calling subscriber, to indicate to him that connec tion has been made at the central ofiice. The subscriber operates the lever 8 by placing a finger in the finger hold 9 and his against one of the ears'or tongues 28, drawingsthe finger downuntilit'contacts with the thumb. This action is repeated any desired number of times, each time releasing the lever and permitting it to return .to zero position. By depressing the lever 8 the teeth of the segment 12 are caused to engage the contact springs and move them both to one side. When the lever 8 is released the clock spring 11 throws the segment back to its original position, and the member 15 engages the-gear Wheel 16 to rotate it, this operating the governor 18 through the toothed shaft 17. As the segment makes its retrograde movement each tooth 13 engages the tongue 22 on the spring '21 and breaks the circuit by'moving it out of contact with the spring 20. Each time the circuit is closed the indicator G is operated.
When the plugis removed battery is restored to the tip side of the line throu h wire d, and when the subscriber again ca ls the magnet 29 restores the target 34 to normal. .Having thus describedmy invention, what I I claim and desire to secure by Letters Patent is v 9 1-.In a calling device the combination of circuitbreaking mechanism for transmitting a series of impulses, a movable operating' member having a finger hold, for actuating said circuit breaking mechanism, and afix'ed limiting member having a plurality of finger holds spaced apart from each other in. the path of movement of the operating-member, said finger hold in the movable member and all the finger holds on the fixed limiting member being Within the span and range of movement of one hand of the operator.
- 2. In a calling device, the combination of circuit breaking mechanism for transmitting 'a series of impulses, a centrally pivoted operating member connected thereto having a finger hold at a point some distance from its pivotal center, and a series of fixed finger-holds arranged in the arc of a circle around saio pivotal center, said movable memberbeing normally held in idle or inactive position at a predetermined point with respect to said are, but adapted to sweep over all the finger holds when actuated through a path limited to a single hand span.
3. In acalling device, the combination of circuit breaking mechanism for transmitting a series of impulses, an inclosing casing therefor. an actuating lever for 'the mechanism pivoted on said casing and having an opening for a finger hold at some distance .from its pivotal center, and a series of fixed finger holds secured on the casing in a curved figure around said plvotal center,
together with means for maintaining the actuating lever when idle in a definite and invariable position with respect to the fixed tive position, and to actuate the circuit.
breaking mechanism in, so doing.
In' testimony whereof I have affixed my signature in presence of two wltnesses.
