JOHN WALDHEIM, OF ELIZABETH, NEW JERSEY, ASSIG-NOR TO UNDERWO OID TYPE- WRI'IER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAVJARE.
TYrEwarrrNe MACHINE.
Application filed July 3; 1922 Serial No. 572,396.
1 '0 all whom it may concern:
Be it known that I, JOHN WALDHEI'M, a citizen of the United States, residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and removal of the machine, and to permit of access to the machine for erasures and other purposes. mentioned have heretofore been made or sheet-metal or di e-castings, lined with felt.
or other sound-deadening material, cutrinto pieces of various shapes, and joined and held to the casing proper by various devices.
An object of the present invention is a casing having no s0unddeadening wallmembers other than the Walls which form the frame of the casing; and in which, therefore, the number of parts and fittmgs may be reduced to a minimum.
In attaining this object of the 'in'vention,
the casing is constructed of beaver-board, fiber or other self-sustaining composition, which is in itself sound-deadening. Preferably the walls of the casing are separate units, so jointed and held together as to as sure the sound-deadening characteristic of the casing. Certain features of the invention relate to clamps by which the desired union of the walls is had; and to certain holding or anchoring means for the clamps, to prevent the same from working loose in the softer material of the casing itself; also to means for holding the hinges to such softer material of the casing, while preserv' ing a smooth interior finish, to prevent fouling of the work-sheets as the latter move over and with the carriage of the machine within the casing.
Other features and advantages will here inafter appear, a
In the accempafqing drawings;
Casings of the character indicated .in dotted lines therein.
Figure 2 is a front view, partly cross-sectlonal, of the casing.
Figure 3 is a detail view, in cross-section, through one of the corners of the casing, to show the'manner in which the walls are held together;
Figure l is a detail view of one of the slot-closing cushions.
The casing is shown as made in two parts, to wit, a body-part and a cover 11, hinged together at 12. The sections 10 and 11 are of some stiff, sound-deadening material, such, for instance, .as beaver-board or fiber. The leaves 13 and 14 of the hinge extend lengthwise of-the 'joint 15 ofthecasing.
The machine 26, within the casing, is pro-.
vided with the usual front feet 27 and rear feet 28. The keyboard-extension 29v of the machine projects through a suitable o em ing 30 in the front wal 31 of the casingbody, The typewriter earriage 32 is mount lower forward edge 37 of the cover and by the upper edge 38 of the front wall 31 of the casing-body. This slot- 36 is, however, practically closed by two resilient, flexible cushions 39 and 40; the cushion 39 being secured by screws 41 passing through lips 37 on the edge 37 of the cover, and the cushion 40 by screws 42 passing through lips 38 on the edge 38 of the casing-body, the
7 screws 41 and 42 being received in metal strips 37 and 38 behind the rear lips 37 and 38 respectively. The cushions, in effect, close the slot 36, being in contact with each other except where the handles 33, 34 and protrude between the same. The yieldable, flexible character of the cushions permits movement of the handles therealong as the carriage is moved in oneor the otherdirection.
walls, and 49. In this WV'hen the 'casing-cover' is open, the typewriting machine may be inserted. 1nto the casing through the open top of the casingbody. In the form of the casing shown, the
machine is inserted with its keyboard-ex "tension tilted downward and forward. Thus tilted, the keyhoardextension is passed through the hole or opening 30 in the front wall of the casing, and is then brought forward, and themachine lowered until the feet thereof rest upon the basepiece'20, with the rear feet 28 thereof in locators 43. These locators are in the form of ears, preferably of metal, secured by screws 44 to the lower edges of the casingbody; and are provided with holes 45 to receive the rear feet. Lips 46, upturned out of the locators, define the holes 45 and provide ample lateral bearing for the feet. To allow for proper play of the keys 47, the front wall of the easing-body, above the keys, may be cut or taperedinward, as indicated at 48.
Clamps, set along thejoints formed by the casing-walls, hold the latter together. These clamps comprise blocks 49, set into thecorners, and having wings 50 projecting into grooves 51 in the inner faces of the casing-walls. Anchoring or holding strips 52, for screws 53, are counter-sunk in the outer faces of the walls, opposite the blocks 49; and the screws 53 pass through the strips 52 and through the casing are threaded into the blocks manner, the walls are not only held securely together, but the joints are held tightly closed, to maintain the sounddeadening character of the casing.
As shown in Figure 2, the casing has the usual upward and lateral outward flare, to provide space inthe upper part thereof, for movement of the carriage in letter-feed and return directions. The cover is supported upon the casing-body at the joint 15, at the rear thereof, by means of the hinges; and, at the front, the cushion 40 supports the cushion 39 of the cover. As shown in Figure 2, the cover side walls overlap the upper edges of the side walls of the casing-body.
The slot- closing cushions 39 and 40 may be readily replaced by'hew ones when they become worn. To facilitate this replacement, the cushions are held between metal strips or bars 55 riveted together so that they may be readily inserted into slots 56 and 57 formed respectively by the lips 37 and 38, The bars 55 are provided with holes to permit the screws 41 and 42 to pass freely through them.
Variations may be resorted to within the scope of the. invention, and portions of the improvements may be used without-others.
