To aitwhom "it may concern:

Be it known that I, BENJAMIN P. HAYES,

liity iuren tion -relates to cases for mechanical telegraph. transmitters of the key board, type, .and' uparticularly adapted for usewith the dew ice disclosed in my application for Letters Patent'ot' the United States, filed October 21, 1908, ,Serial Number 458,888, to which.reference may be had for more detailed information regarding the use of the case, and the combination of a suitable machine herewith.

My invention has for its principal object to provide a caseo't' the class mentioned, \i'hichis neat andattractive in appearance. simpleand economical in construction, and within which a transmitter or like mechanism may be quickly antt'securely housed.

A further object of my invention is to provide a case which, under certain conditions, may be swung away to expose a contained mechanism without becoming wholly disconnected from such mechanism.

These and other objects are accomplished by improved details of structure, the preferred forms of which are illustratedin the "accompanying drawings, in which F igure I is a perspective oi the transmitter case, the removable lid thereof being partly broken away, and. the seat being omitted.

,the top 4 having a rectangular opening therein, and thtwi'ront -53 av "keyboard open m 6.

For closing the opening 5, a lid or plate 7, shown in Fig. II. is provided; said lid having secured to its under side, near the for.- ward or lower edge, one or more tongues 8, which project beyond the edge of the opening On the under side of the lid, near the back or upper edge, is a boss 9 to which is secured a rearwardly projecting lug t); such lug being projected only to the edge of the lid so that the latter may seat Within the. opening 5. .9

1O designates a latch which is adapted to project between the lid and tha-la aaiml has a shank 11 passing through a forward and rearward slot 12 in the top of the body C. The latch has bifurcations 10" which straddle a stud 13 forming a stop to limit the opening movement of the latch. 'IVhen the latch is retracted, the lid 7 may be rcmoved from the case, as will be readily understood.

Positioned at one side of the keyboard opening 6 is a manual key lat for sending signals or cha'acters by the opening and closing of a circuit and comprising a vertically movable stem which is held. within a boss 14-, cast integrally upon the body C, as shown in Fig. I. One leg of the key is connected by a wire 15 with an insulated binding post 16 at the rear of the case. The key 1 1- and the companion binding post 17 are grounded'on the case, which is preferably metallic and a conductor of electricity. The thumb screws of these binding posts are covered with insulating material, as shown vin Fig. VI, wherein 18 designates metallic nuts threaded on the screws 19, and 20 designates the insulation covering. This device ismuch to .he recommended 1n practice, as

it relieves the operators o-f-th'e danger of sustaining shocks when connecting or disconnecting'wires. The bases 2l= of the bind-' ing posts may also be'exteriorly covered with insulation, 22, asv also shown in. Fig.

' qVI, and for the same purpose as the coverings 20 just described. I

a The connecting wire 15', before mentioned, is guided or supported within the case by have shanks assing through perforations in commercial screw eyes.

the case bo y, and preferably riveted in lace. The eyes andshanks may be made in. the, form of spring cotters, or may be made of round sectioned wlre formed as for 24 designates conical-ended pivot screws which pass throu h threaded openings alined with each other in opposite sides of the case and pivotally support the seat S of the transmitter. On the outer sides of the case around the threaded openings, the case is formed with bosses 25, and each screw 24 is provided with a lock-nut 26. The seat S 00111 rises a pair -0t lateral lugs 27, which are etachably secured to the body C, preferably by means of the devices shown in Fig. IV,

Cast on each side of the body C, within a swell 28, is a boss 29, in which is drilled upwardly and vertically a screw hole 30,

tapped to receive a. thumb-screw 31. This screw comprises the head 32, the screw proper, 31, and a stem 33, of less diameter than the part 31.

The hole through the lug 27 is threaded so that the screw 31 may be held therein after it is'iunscrewed from the swell 28- and be carried' 'with the seat when the latter is body C through the pivot screws 24,.the

body C being preferably swung back while the connection is being made to facilitate the manipulation of the parts.

When the screws 24.- have been adjusted so that there may be a free pivotal cofiperation of the case body and seat without lost motion, the case body is lowered and the screws 31 (WhlCh have been carried in the threaded openings in the lu s 27) are turned into the threaded sockets in the bosses 29,

so that a rigid connection is made between the parts and a' firm base provided for the mechanism (not shown), which will obviate turning of the seat in the case when the mechanism is in use. 1 7

It is readily apparent that when it is desired to reach the mechanism, as for cleaning or repairing, the screws, may be removed from the bosses 29 and the body- Cv turnedback on the pivot screws 24 'to expose the interior mechanism The advantages of the structural improve ments heretofore described are thought to be so readily apparent from "the foregoing description and accompanying drawings,

that further mention thereof would be merely cumulative. I

' While I have specifically referred to the telegraph transmitter of my former application, such reference has been for the purpose of more clearly describing my present invention and notwith the intention of limiting the scope of .the patent.

Having thus described my invention,- what I.claim as new therein "and desire to secure by Letters-Patent is w )7 1. A keyboard transmitter .case' comprising a body portion, a seat pivotally mounted within the body portion, and means for an choring the seat against pivotal movement, 2. A keyboard transmitter case comprising a body portion; aseat located within the body portion and havingone end pivotally connected therewith, an means for de- 'tachably connectingj the opposite end of the seat with. the body portion.

3. *A keyboard transmitter case ing a body portion;.a" seat having a flat bottom, socketed edge flanges and laterally projecting lugs; ivot members? carried by the body and ro ecting int'o the seat sockets;

and means whereby the seat lugs may be detachably secured to the case body.

4. A keyboard transmitter case comprising a. body having. downwardly opening screw holes at opposite sides thereof, a seat extending between said screw holes, screws passing through openings in said seats and into said screw holes, heads on said screws,

comprisand means for retainingthe screws in engagement with said. seat when the seat is "detached.

5. A keyboard transmitter'case comprising downwardly opening screw holes at opposite sides thereof, a seatextendingbetween said screw holes and provided with apertures, screws passing through said apertures and into said screw holes, and heads on said screws, said screwshaving reduced shanks-between the screw part proper and the heads, and the apertures in the seat being threaded to receive said screws.

6. A keyboard transmitter case comprising a body member having downwardly facing screw holes in-opposite sides of its under lugs projecting later-ally beneath the screw holes in said body member and having apertures of less diameter than said screw holes,

but arranged concentrically therewith, pivot ends of said shanks, substantially as and for members carried by the body member and the purpose set forth. projected into the side sockets of said seat, In testimony whereof I affix my signature and screw members having threaded porin presence of two witnesses.
