V TYPEWRITEB SCREEN.

Application filed November 19, 1921. Serial No. 516,265.

To all whom it may concern Be it known'that I, ELMER CLYDE Moon, a citizen of the United States, residing at Sheepshead Bay, in the county of Kings and State of New York, have invented certain new and useful Improvements in Typewriter Screens, of which the. following is a full, clear, and exact description.

This invention relates to attachments for typewriting machines to facilitate instruction in the touch system of typewriting, and has for an object to provide a vision screen for attachment to all makes of typewriters, so as effectively to conceal the keyboard thereof from the view of the operator without interfering with or hindering the usual manipulation of the typewriter; A

further object is to provide an attachment for this purpose which can be quickly and easily attached to or detached from the usual forms of machines, and which is simple and inexpensive. Other objects and advantages will be apparent from the following description of an embodiment of the invention, and the novel features of the invention will be particularly pointed out in claims.

In the accompanying drawing:

Fig. 1 is a side elevation of a typewriter with one form of my improved screen attached thereto;

Fig. 2 is a front elevation of the same;

Fig. 3 is a side elevation of a typewriter with another form of my improved screen attached thereto;

Fig. 4 is a plan of the same; and

Fig. 5 is a fragmentary sectional. elevation of the same.

In the embodiment of the invention illustrated in Figs. 1 and 2, a flat sheet 1 of opaque material, which may conveniently be sheet metal, has a size and shape substantially coextensive with the keyboard 2 of a typewriter, and is provided with a wire binder 3 around the edges of three sides thereof, the edges of the sheet being preferably rolled around the wire toprovide a firm attachment thereto. The extension or ends 3 of the wires extend downwardly from the sheet, and each is bent at a point intermediate of its length to form a shoulder 4, and at its extreme end to form a hooked terminal 5, the shoulder and hooked terminal together forming a spring clamp for engagement with the frame of the typewriter machine The preferred manner of clamping the wires to the frame is to place the hooked terminal beneath the side frame immediately in the rear of the forward supporting feet 6 of the frame and the shoulder i above the forwardly extending side arm 7 of the frame. llhe wires, which are preferably of iron, have sufficient resiliency so that the extensions will yield and permit snapping of the ends over the typewriter frame when the screen is applied to the typewriter frame, or to yield and permit disengagement of the screen from the frame when its use is not longer desired. It will be seen that the intermediate portion of the binderwire is substantially U-shaped, having a distance between the arms of the U substantially equal to the length of the key board, and the opaque sheet extends across between the arms and the base of the U. The opaque sheet of the screen is supported above and spaced from the keyboard, so that the usual manipulation of the keys by the fingers in the act of typewriting is not interfered with and visual observation by the operator of the movements of his fingers is prevented. The support of the screen is such that the hands may be easily moved from under the ends thereof at the end of each line to return the carriage into position for writing a new line.

In the embodiment illustrated in Figs. 3 to 5, the flatopaque sheet 8 is similar to sheet 1 and provided along its peripheral edges with a wire binder 9, the binder extending along both side edges, the forward edge, and also along the rearward edge for a portion of its length from the right-hand corner, the ends of the wire binder extend ing forwardly a short distance, then to wards the sides of the machine, and then perpendicularly toward the supporting surface upon which the typewriter rests. The ends 10 of the wire are slidably received in a pair of spaced bearings 11 and 12 of the upstanding arm of a supporting element 13 having a flat end portion 1a, the latter being adapted for disposition beneath the forward feet 6 of the typewriter frame, so that when the typewriter frame is placed, or secured upon the supporting surface, the supporting element will be held against dis placement. A set screw 15 in the supporting element between the spaced bearings 11 and 12 may be adjusted to engage with the and downwardly over the keyboard from the right-hand end of the carriage. WVith this arrangement and this type of machine it is unnecessary for the operator to move the hands from beneath the screen in order to manipulate the carriage lever for returning the carriage to its position for a new line- The embodiment illustrated in Figs. 1 and 2 may be used on machines having th forwardly and downwardly extendingcarriage operating lever 16, since the screen is spaced forwardly of the frame sufficient for clearance ofthis lever; it being necessary, however, in this case to move the hands from beneaththe screen in order to manipulate this lever. This type of shield may be quickly and easily applied to the typewriter frame by snapping the resilient end portions over the frame, or removed therefrom. The type of shield shown in Figs. 3 to 5 is also easily applied to or removed fromtypewriters of any form whatever and is also ustable to any desired height. Both types of shields are simple in construction, light in weight, attractive in appearance, inexpensive to manufacture, and are effective in use.

It will be obvious that various changes in the details and arrangement of parts herein described and illustrated may be made by those skilled in the art within the principle and scope of the invention. I

I claim:

1. In an attachment for typewriters, a sheet of opaque material having a binder of wire alongthree edges and from one end partly along the fourth edge, the ends of the wire extending" forwardly from the edges and then to the sides of the frame of a ma- 1 chine to form a support for the sheet and hold. it above and spaced from the keyboard,

said fourth edge and the binder wire leaving' it forming together a slot through which the depending spacing key may project and travel during the movements of the carriage and permit operation of the spacing key from beneath the screen.

2. In an attachment for typewriters, a

opaque screen substantially co-extensive in size to the key board, having extensions turned downwardly at each side of the ma chine, said extensions having terminals for supporting the screen upon the typewriter supporting surface in a desired spaced position above the key board of a typewriter.

i. In an attachment for typewriters, an.

opaque screen substantially co-entensive in size to the keyboard, having extensions turned downwardly ateach side of the machine, said extensions having terminals adjustable thereon for supporting the screen upon the typewriter supporting surface at diflerent desired levels above the keyboard of r a typewriter.

In an attachment for typewriters, an opaque screen. substantially coextensive in size to the key board, having extensions turned downwardly at eachsideof the machine, said extensions havingterminals upon which the feet of a typewriter may rest to hold the screen in a desired spaced position above the keyboard.

.6. in an attachment. fortypewriters, an opaque screen substantiallyco-extensive in size to the key board, having extensions turned downwardly at each side of the machine, said extensions having; terminals adjustable thereon upon which the feet of typewriter may rest and support the screen at different levels above the keyboard.

7. an attachment for typewriters, an opaque screensubstantially .co-extensive size to the keyboard, supportingertensions for said. screen extending downwardly at each side'of the typewriter, the extension at one side of the typewriter extending parallel with and spaced from the inner edge of the screen, part way-across the machine, before extending; forwardly to connect with the screen, so as to form with the inner edge or the screen aslot through which the depending spacing key may travel during the carriage movements, whereby the spacing key may be operated to return the carriage and space the roller from beneath the screen.
