Specification forming part of Letters Patent No. l66`,S76,dated August 17, 1875; application tiled August 5,1875. Y

To all lwhom it may concern:

Be it known that LMARGUS L. M. HUSSEY, of Menlo Park, in the county of Middlesex and State of New- Jersey, have invented certain new and useful :Improvements in Telegraph- ()perating Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, .which will enable others` skilledl in the art to which it pertains to make and usethe same, reference being had tothe accompanying drawing and to the letters of reference marked thereon, which form a part of this'specitication.

Figure l is a side elevation. Figa-2 is a perspective, showing; the under side of the top table. Figl is a plan, showing the top of the.

ed that a single key 'may be used tov operate one or any number of difierentwires; second, in so constructing the machine that the operation of connecting the key with any given line serves tolnake the proper connection of the sounder and local battery; third, in so constructing and attaching the machine that it will be impossible to open any wire but the onein use, while all the other wires are closed; fourth, in so constructing the machine that there is but a single point for breaking the connections, and that a platinum point.

In the accompanying drawings, Arepresents -the keyarm, provided at c with the usual` spring. This arm is mounted upon suitable bearings in the sockets or standards B, which are placed upon and suitably secured to the upper and revolving table C. This table is centrally connected to and uponthe lower table D by the main post E. The top or upper end of this post is affixed to said table C. It

' passes down through said table D, and also ular Wire,

the operating-table, beneath which it is secured `and held by a nut and Washer or anylike orordinary contrvance for that purpose.

upper and lower tables, and` tween the said with said main post passing centrally Vthrough them, are the disks F F'. The'use or office of these is to afford the surest and steadiest bearing for the upper table. In order to make them work moreV steadily lI have hollowed' lthem out somewhat, so as to have an annular bearing-face on the under side of F and on the upper side oi F. The disk F is connected to the upper table by pin f, and F' to the under table by pin f'. Eachione ofthe circuitplates Gr is rigidly attached at the end byone of the main-line'posts H, while their outer end extends lover the posts I, each ofwhich has in its top a platinumpoint, i. The outer end of each circuit-plate is notchedV at g. This vis adapted to receive and hold the latch end a. ofthe springfcatch A. This catch is pivoted in the arm A at such a point that it can move freely outside the edge oi' the upper table, and, being rigidly attached to said table, it moves with it,`and said table can be also moved byit. According as it is desired to use any particthe said latch end is pressed down through said slot g, and when it passes through the same and below said plate G, the spring a", acting upon the upper part ot' A', causes the latch to come under and engage with said plate, and lift it up ntorecess (y, so that it is raised thereby abpve the top of the platinum point i in post I, and held lirmly against the lower end of post K, which is set in and through the arm A,and extends down through a hole or. opening in the top table G, and, projecting into recess G', comes directly over the platinum point in said post I. The recess C is sufficiently deep to afford all necessary play of said plate in Working the instrument.

The key may be adjusted by means of a screw, Z, which passes through the extension l of the piece L, the arms l l of which hold the key on the upper and under side. This piece L is secured to the upper plate C by said screws. The connection with the local and only battery is made by means of post M, which connects with the circle-connector M '2 l wenn;

in the upper face of the 'table D, and this in. turn is made vto "connect with the sounder` N, according as the operator revolves the key or said upper'table.

When the key isv not in use the outer end of said spring falls between any two of lsaid sounder-posts N, thus opening the local-battery circuit, which'will, of course, remain open until the key is brought into use again. Of

course, I propose to use any number of posts H, I, and N that may be necessary to adapt my invention to use, and any number of wires, and otherwise multiply the parts for same purpose. This lwould obviously be mere du-l plication of parts,and is not now dweltmore particularly u pon While I have hereshown the plate D'stationary-and G movable,to bring the `key into circuit. with any one line, it is-evident that this lrelation of moving and stationary parts may be reversed without departing from the spirit of cuits pass, lone plate being movable in relamy invention.

The detailof constructing and operating lmy device or invention according to ythefabove will be readily understoodby all persons skilled yin the art to whichits use and construction be,

long; and the advantages to be derived from my said invention-,as thusfsubstantially illustrated and explained, are of very great consequence. By means of itthere will :be a large saving or gain yin .mere space or room `in van; office, likewise in the time of the operators,

and inthe expenseof local and main batteries, and delay off cost of instruments, and trouble continually clean-ing and repairing the same. `There will, vin `addi-tion., be vno .liability of having Wires lett open by any canse. For these.

`ative lever, of an auxiliary such circuit is not in use, gle contact-point is needed, substantially as and 'spring O 'wi'tnposts I consider new,

and desire to secureby Letters Patent, is-

1. The combination, with 'a single key,of

oneor more anvils, each representing a di'erf 'en't'wireor circuit, and all so arranged that the movement of said key or its support serves to bring said fkey into suitable connection with any desiredone of 'said wires or circuits, substantially as described.

2. The combination of a single key-lever, contact-point, and anvils, connector and local contact, so arranged that upon the movement of said key to connect with any one'of the line-circuits the local-bat-v tery and proper sounder connections are simultaneously made, substantially as and for i the purposes set forth.,

3. The combination, with the main or operor spring lever, adapted `to hold the 'main circuit closed when whereby but a sinand for the ypurposes set forth. A

4. The'combina'tion of two 'disks or plates, one provided with a single key-lever, vand the other provided with `one or Amore contactpoints, through-Which various telegraphic cirftion to the other, whereby the movement 'of 'fone plate upon the other brings the key-lever into position vto operate any desired circuit of theseries, su-bstantiallyas sjet forth. v

-5. The combination of the key, the table C,

M', and post N ,n substantially as and for the purposes set forth. n

6. The ycombination of the key Auand latchspring A a with the circuit-plate G, posts K and I substantially as Vand for the purposes set forth. I y,

In testimony'th'at Iv claim the foregoing as 'my own I a-x my signature fin' presence of two witnesses. t

as described,with a and many morelike reasons, not n ow neces. sary to'recite,lthe l:utility of my said invention will be readily understood.

Having thus described my invention, what .I
