TELEPHONE-SUPPORT.

SPECIFICATION forming part of Letters Patent No, 294,297, dated February 26, 1884., l

" l Application filed July 20, 1883. (No model.)

To @ZZ whom t may concern:

Be it known that I, GEORGE AMBRosE WIL- KINs, of Philadelphia, in the county of Philadelphia, Stateof Pennsylvania, have invented a certain new and useful Improvement in Telephone-Supports, of which the following is a description sufficiently full, clear, andexact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a side elevation of my improved support, the base being shownin section; Figs. 2 and 8, views of the arm-hinge or joint detached; Fig. 4, a view of the cam-sleeve and collet; Fig. 5, a view of the disk removed, and Fig. 6 a modified forni of the switch.

Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.

My invention relates to that class of telephone-supports which are adjustable and provided with means for automatically making and breaking the circuits, being more especially designed for useon a table or desk 5 and it consists in anovel construction and arrange ment of the parts, as hereinafter more fully set forth and claimed, by which amore eii'ectivedeviceof this character is produced than is now in ordinaryuse. The nature and operationof. the improve ment wilLbe readily understood by all conversant with such mattersfrom the following explanation. v A Y In the drawings, `A represents the pedestal, which is hollow, and. provided with the foot B, designedrto rest upon any ordinary desk, table, or shelf, C, and support the superposed parts, hereinafter described.

A hollow standard, D, is tted to slide vertically iu the pedestal, and extends downwardly through the same into the foot B. Disposed on the lower end 'of the standard there is a hard-rubber disk,.m, which is securely attached thereto by the screw b.

Secured to the upper end of the pedestal, and renderedv adjustable thereon by the setscrew E, thereA is a sleeve,.F, which is pro- '50 vided on its opposite sides with the corresponding cams or elevations, a: x, and between the cams with corresponding depressions, o o.

Attached to the standard by the screw f, near thetop of the pedestal A, there is afixed collet, G, provided with two horizontally-projecting studs, e z, which rest in the depressions o e of the sleeve F when the support is not in use.

Projecting horiontally from the standard,

either side of the arm J. The auxiliary arm carries a slide, P, which is rendered adjustable thereon by the set-screw g, and supports an ordinary telephone-transmitter, Q.

Fitted to slide horizontally on the sleeve L there is also a carrier, R, provided with a setscrew, h, and disposed on this carrier there is a slide, S, provided with the set-screw i, the carrier being made adjustable on the sleeve and the slide on the carrier by their respective screws h i.

Projecting upwardly from the slide S there is a hub, j, and tted to turn or swivel in a socket formed in said hub there is avertically-arranged stud, k, having the clamps -or hoop 'Il at its upper endyin which an ordinary telephone-receiver, U, is secured and held in -such a manner as to be readily turned or swiveled on the stud k in the hub. V Attached to the table C -by the screws t there are two horizontally-arranged switches or springs, h h', the spring h being arranged between the overhanging screw 14, supported in the bracket 16, and the metallic button 15 on said table, and the spring h arranged beneath the overhanging screw 17, disposed in the bracket 18, both of said brackets being supported on the table C.

An ordinary battery, W, is disposed near the pedestal A, and leading from this there is roo a wire, 19, connecting with the transmitter Q, and also a wire, 20, connected with the screw 17. A wire, 21, connects the spring 7L at t with the transmitter Q, and there is also a wire, 22, connecting the bell 23 with the button 15, and a wire, 24, connecting the screw 14 with the transmitter Q, an ordinary in-line wire, 25, being connected with the screw t of thc spring h. A wire, w, also leads from the transmitter to the receiver U, the receiver being connected Awith the ground by the wire 1' in the ordinary manner. An opening is formed at e in the standard A for the transmitter-wircs, and also an opening at q for the receiver-wire w.

In the use of my improvement the camsleeve F is secured by the screw E in such a position on the pedestal A that when the studs e are on the elevations or cams x x the arm J, carrying the transmitter and receiver, will be in position for use, as shown in Fig. 1, the stand-.1rd D being elevated or at its highest point, the springs or switches h h in contact with the screws 14 17, thus closing the batterycircuit, breaking the bell-circuit, and connect- Ving the in-line with the transmitter and receiver. After the instrument has been used to receiye or send a message, or both, the arm J is released, the weight of the standard and its connected parts causing the studs e to slide down the inclined sides of the elevations or cams a: and depress the standard D, bringing the disk m into contact with the switches h h', and forcing them downwardly out o'f contact with the screws 14 17, breaking the batterycircuit, bringing the spring h into contact with the button 15, thereby bringing the bell into circuit and disconnecting the transmitter and receiver, in a manner which will be readily obvious without a more explicit description.

1t will be obvious that when the instrument is in use the bell will be out of circuit and the battery in circuit, and that the message does not have to be sent through the bell, which is then out of circuit. Vhen the arm is released after using the instrument, as described, the weight of the standard and the parts it carries will act by gravitation to force the studs z into the depressions @,and as they ride downwardly over the inclined sides of the cams x the standard will thereby be turned or partially rotated, and the arm J swung back out of the way of the operator.

-Instead of the cam-sleeve F and studded collet G for turning the standard D, a coiled spring may be used, the spring being arranged within the pedestal or in any other convenient position, and actingtorsionally to swing the arm J. Vhen a spring such as last described is used to turn the standard,the disk m is dispensed with, and .an ordinary switch lever or levers, y, as seen in Fig. 6, are connected to the lower end of the standard in such a manner as to be operated thereby in opening and closing the circuits; but I prefer to use a cam-sleeve and studded collet for this purpose.

It will be obvious that the arm J may be lengthened, as desired, by means of the sleeve L; also, that the receiver may be adjusted in any desired position on said sleeve by means ofthe carrier R and screw h; also, that the arm N may be readily swung into a convenient position for use, and the transmitter adj usted thereon, as desired, by means of the slide I) and screw g,- also, that the arm J may be elevated or depressed and secured in any desired position by the rule-joint K. As the arm J is automatically folded or swung back out of the way or against the wall when released, it will be seen that there is no danger of accidentally leaving the battery-circuit closed when the instrument is not in use-an accident which is liable to occur where holders of the ordinary construction are employed.

It will be obvious that the disk m, provided with means for moving the disk vertically,.in combination with the switches hh', button 15, screws 14 17, and proper conducting wires, constitute switches which perform the ordinary functions of electrical switches in telephonie instrument-s; also, that as many of said switches may be used as desired.

I do not confine myself to mounting the receiver on the arm J and the transmitter on the arm N, as the positions of these may be reversed, if desired. One may also be supported independently of the other or entirely disconnected from the arm J, although it is preferable to support them both on said arm and provide the auxiliary arm N for the transmitter, as shown. A small inclined table or deskmay also be attached to the pedestal A,I"or convenience in writing dispatches, if required, the desk being made vertically adjustable on said pedestal in any convenient manner.

' Having thus explained my invention, what I claim is- 1. In a telephone-support, the standard D, provided with the studded collet G, in combination with the pedestal A, provided with the cam-sleeve F, substantially as and for the purpose described.

2. In a telephone-support, the disk m, in combination with the button 15, switches h h', screws 14 17, standard D, proper conductingwires, and means for raising and depressing said disk to close and open the circuits, substantially as set forth.

8. The combination of a pedestal or support provided with a cam-sleeve, a standard adapted to turn in said pedestal, provided with a studded collet, and a swinging arm attached to said standard and carrying a receiver, substantially as described.

4. In a telephone-support, the carrier It, provided with the screw h, in combination with the sleeve S, provided with the screw i, clamp T, sleeve L, and arm J, substantially as described.
