' TYPEWRITER CASING Filed Feb. 1. 1941 Patented Apr. 13, 1943 UNITED STATES PATENT OFFICE 2,316,617 TYPEWRITER CASING Giuseppe Prezioso,'Yverdon, Switzerland, assignor to E. Paillard et ACie S. A., Yverdon," Switzerland,a corporation of `Switzerland l A y YApplication February 1, 1941, serial Nt. 377,054,
In Switzerland February 23, 1940 claims. l(01.- 1971-136) The present tendency in the manufacture of typewriters is to provide the same with a casing which houses all of the mechanical parts with the exception of the keyboard, thereby not only to conceal them from View, but also protect them against accumulation of dust and in a measure to silence operation. This casing must of necessity be constructed of removable parts or sections to give access to the internal mechanism for cleaning and maintenance in general.
A primary object of the present invention is to provide a typewriter casing including a front wall or plate which conceals the type bars and ribbon spools, said plate being formed so that it will hold or support a note book or the like at a Convenient viewing angle between the keyboard and the platen. In other Words, the invention provides a notebook support which in itself is a part of the casing of the machine and which supports a notebook in such a way that the platen, notes `in the book, and the keyboard are all three visible simultaneously, thereby avoiding the necessity of a separate note book support or copy holder.
A preferred and practical embodiment of the invention is shown in the accompanying drawing in which:
Fig. 1 is a perspective viewrof a typewriter casing embodying one form of the invention, with the front w'all of the casing shown in position for normally supporting a note book or the like.
Fig. 2 is a perspective view similar to Fig. 1 showing the front wall or plate swung forwardly on its pivotal support to permit access to the type bars.
Fig. 3 is a perspective View showing a modied form of the invention, wherein the front Wall is removed from the casing, and illustrating vthe use of fastenings for securing the front wall to the casing.
Similar reference characters designate corresponding parts throughout the several figures of the drawing.
Referring to Figs. 1 and 2, it will be observed that the typewriter includes a casing having side walls A which are provided with the centrally located or intermediateupstanding portions A' having a substantially horizontal top wall a and the downwardly inclined front and rear edges respectively designated as b` and c. The front edge b extends in the direction of the portion B of the side wall which lianks the keyboard and the rear inclined edge c 'extends in the direction of the platen carriage clearance C.
The front plate or wall I of the casing is designated generally-as I and spans the distance between the opposite side Walls A of the casing and also extends vertically between the top edge a of the side wall downwardly to a point near the end of the front inclined edge b of said side wall The upper or top end of the front wall I is provided with a rearwardly extended flange Ia while the bottom edge is provided with a forwardly offset angularly disposed flange 3 which constitutes a shelf or support.
The said front wall or plate I, according to Figs. 1 ancl-2 of the drawing is preferably hingedly connected to the side wall A by a hinge connection which consists of the perforated ears 2 struck out from the side wall A and adapted to receive an offset pintle preferably located substantially at the junction of the ange 3 with the body of the front wall I.
According to the form of the invention shown in Figs. 1 and 2, it will be apparent that the front plate or wall I is hingedly supported on the side wall A so that it may assume the normal position shown in Fig. 1 or the open position shown in Fig. 2 when it is desired to have access to the type bars.
Referring to Fig. 3, it will be observed that the front plate or wall I has the same characteristics as described in connection with Figs. 1 and 2 and the only difference resides in the manner of mounting the front plate or wall on the casing or machine frame. As will be observed from the drawing, the front plate or wall I is provided,
-at its underside, with suitable guide marks or guide means 4 intended to cooperate with marks 5 on the side frames A for placing the front plate or wall in position.
Inboth forms of the invention, the front Wall or plate I, recessed as indicated at 6 to receive a note book or other note-bearing record which is supported at a proper viewing angle so that the operator of the machine may conveniently read the notes during typing.
Owing to the angularity of the front edge b of the side wall A, the front plate or wall I is supported in a rearwardly inclined or tilted position as will be apparent from the drawing.
I clai-m:
l. In a typewriting machine adapted for visible typing and wherein thev type bars and ribbon spools are located between the platen and the keyboard, a casing including opposite side walls, each having an intermediate upstanding section formed by a substantially horizontal top edge and downwardly inclined front and rear edges respectivelyleading to a portion flanking the keyboard and a portion providing platen carriage clearance, and a rearwardly inclined front wall for masking the type bars and providing a note book support between the platen and the keyboard, said front wall extending transversely between and being supported on the inclined front edges of the upstanding sections of said opposite side walls, a rearwardly extending flange at the top of the front wall to overlie the ribbon spools, and a forwardly and outwardlyextending book supporting ange at the bottom of the front wall.
2. A typewriting machine according to claim l wherein the central area of the lfront wall is reeessed inwardly. l l
3. A typewriting machine according to claimrl wherein the front wall is to the side walls of the casing.
4. A typewriting machine according toV claim -1- wherein the front Wall is provided with guide hinged at its lower edgelmeans for positioning the same relative to the side walls of the casing.
5. In a typewriting machine adapted for visible typing and wherein the type bars and ribbon spools are located between the platen and the keyboard, a casing including opposite side walls each having an inclined front edge respectively leading to a portion iianking the keyboard, and a rearwardly inclined front wall for masking the type bars and providing a notebook support between the platen and the keyboard, said c front wall extending transversely between and being supported on the inclined front edges of said side walls, a rearwardly extending flange at the top of the front wall to overlie the ribbon spools, and a forwardly and outwardly extending book supporting flange at the bottom of the front wall.
