XVILLIAM H. EOKERT, JOHN A.'SEELY, AND EDWARD A. EOKERT, OF GIN- OINNATI, OHIO, ASSIGNORS TO THE AMERICAN BELL TELEPHONE COM- PANY, OF BOSTON, MASSACHUSETTS.
COMBINED TELEPHONE-RECEIVER AND CIRCUIT-BREAKER.
SPECIFICATION forming part of Letters Patent No. 313,409, dated March 3, 1885.
I Application filed April 21, 1882. (No model.)
To aZZ whom, it may concern.-
Be it known that we, WILLIAM H. ECKERT, JOHN A. SEELY, and EDWARD A. EOKERT, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in a Combined Telephonic Receiver and Circuit-Breaker, which improvement is fully set forth in the following specification and accompanying drawings,in which- Figure 1 is a central longitudinal sectional View of a telephone equipped with the improved circuit-breaker, and Fig. 2 is a perspective elevation of the equipment for the mouth of the telephone and the movable plate for making and breaking the circuit.
The object of our present invention is to provide a telephone or telephonic receiver with switching mechanism so arranged that when the operator desires to use the instrument he places the mouth of the telephone to his ear in the usual manner and presses against it, which motion automatically throws the telephone, transmitter, and battery into the circuit, as will be now fully set forth.
Referring to the accompanying drawings, A represents the bodyof the telephonic receiver, made in the ordinary manner, and having four binding-posts, B O D E, at the lower end, instead of only two, as now usually constructed. F G represent upper and lower disks, somewhat larger in diameter than the head A of the telephone. The upper disk, G, has an aperture, G, or central opening, which permits the flaring mouth H of the telephone to 5 pass through. Thus the disk G rests on the head A of the telephone. The lower disk, F, has also a central aperture or opening, F, and is slipped over the telephone from the lower end and brought up against the under side of the head A. The two disks F G are held rigidly to each other by means of the brackets I, four or more of which are employed for this purpose.
It is obvious that various modifications of these disks may be made. Thus the head A The only object of these disks is to provide a support for the movable headpiece K, which will now be described. The disk K is made as large in diameter as the disks F G beneath, and has a central aperture, K. Centrally it is depressed, and the outer edge of the disk is also preferably bent or curved, so that the car of the operator will rest in the aperture without inconvenience when in use.
J J represent legs, which pass through the disks F G, and are vertically movable therein. The legs or rods project above the upper disk, G, a suitable distance, and the head-disk K is-permanently secured to these rods or legs J. Springs L on the rods J are interposed between the disks G K, and the lower ends of the rods J are provided with pins M, which rest against the under side of the lower disk, F, to prevent the rods from coming out, and also to limit the distance that the springs'L may move the head-disk K from the upper stationary disk, G.
It is obvious that the lower ends of rods J may be provided with nuts to answer this same purpose.
It will be noted that if pressure is exerted downwardly on the disk K it will move toward 7 5 the stationary disk G. The disk K may beoof any other shape to accomplish the same purpose. In fact any form will answer, so long as it is adapted to be moved to and from the telephone by pressure against the ear or head of the operator.
On the upper face of the upper stationary disk, G, at one side, are two right-angle springs, N N, secured thereto by screws or bindingposts 0 O. The upturned ends of these springs abut each other, as shown.
On the under side of the movable disk K, directly above the uptu rned ends ofthese springs N N, is a wedge-shaped button, P, which projects down between the two upturned ends P of the springs N N. This button in the present instance is composed of insulating material. It maybe made of conducting material if the springs N N are so arranged that when the movable disk K is in the normal position the button forms the connection between the two springs N N. In this latter case the connection between the springs N N would be broken when the disk K is moved toward the stationary disk G. As shown in the present drawings, however, the ends P are connected atall times except when the disk K is moved downwardly, causing the Wedge P to separate the ends 1?, and thereby break the connection. The spring N has an upwardcurved extension, Q, which forms a contact with the downwardly-curved spring R, attached to the under side of the movable disk K. When the disk K is at its highest limit, there is no contact between the springs Q R, but when the disk is pressed toward the stationary disk G contact is made by a rubbing connection, which keeps the contactpoints at all times bright. This is also true of the wedge-shaped-button circuit-breaker between the springs N N.
Referring now to the circuit-connections, it will be seen how the device is manipulated.
S is the line-wire attached to the bindingpost B. T is the wire which conducts the circuit from binding-post B to spring N U, the wire from the opposite-spring, N, to bindingpost 0 and to the ground; V, the wire connecting spring R and helix; WV, the wire connecting helix with the binding post D, which 'leads to the transmitter and battery, and X wire from battery-post E to spring N on permanent disk G.
The operation is as follows: When the telephone is not in use, it is not desirable to permit the current to pass through the telephone, transmitter, and battery. The current, therefore, in this invention proceeds from the linewire through wire T, springs N N, and wire U to the ground. WVhen the operator wishes to use the instrument, he grasps it in the ordinary manner and places the mouth of it against his ear, pressing it slightly, so as to cause the wedge-shaped button P to break the contact between the ends 1?, and at the same time to establish a connection between the upturned end Q and spring R. The current, therefore, passes up the wire T to binding-post O, thence to spring B through wire V to helix, from helix through wire W to the transmitter,
thence to the battery, and up to binding-post E, and through wire X and wire U to the ground.
Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. The combination, with a telephone station apparatus, of a switch consisting of a movable plate carried by the receiver and supported in front of the ear-piece thereof, and contacts and connections arranged so that said switch is shifted to connect in the telephone apparatus by application of said receiver to the ear, substantially as described.
2. The combination, with a receiving-telephone, of a movable switch or plate supported in front of the ear-piece thereof, and means, such as a spring, for holding said switch in position to cut out the telephone until shifted by pressure, substantially as described.
3.
