TYPEWRITER ACCESSORY.

Application filed March a, 1925 Serial No. 13,812.

v The object of this invention is to provide certain convenient featuresin the form of accessoriesto be used jointly or separately in connection with a typewriter, and consisting of a casing or hood for covering and protecting the machine and for deadening its sound, an erasingtable provided with means for gauging the correct position of the last printed line upon the paper, and a movable copyholder located above the typewriter and situated directly in the vision of the operator when sitting in a normal, upright position.

With this and other objects in view the invention consists in certain constructions, improvements and combinations as will hereinafter be fully described and specifically pointed out in the claims hereunto appended. While this-invention may be modified to suit different styles of typewriters it is particularly applicable to a power typewriter, in which the motions of the carriage are under key-control, and in the accompanying drawings the invention is shown adapted for use in connection with the machine illustrated and described in my application for power typewriters, Ser. No. 13,613 bearing even date with this application.

In the accompanying drawing, Fig. 1 is a sectional side-elevation of the casing and other accessories, Fig. 2 is a partial end-view of the same, and Fig. 3 is an enlarged View showing the manner of locating the casing in relation to the typewriter by means of handles.

Referringto Fig. l, A is an outline of the power typewriter already referred to, and whicheXcept for the keyboardis completely covered by the casing B. This casing may be constructed of any suitable material, and its top is provided with two doors C and D, between which is a narrow aperture for the printed portion of the paper to exit by. The front door C is hinged at C and when opened assumes the position indicated by dotted lines. This door is provided with a glass plate in order to make the writing visible when the door is closed. The object of this door is largely to give the operator access to the machine when certain adjustments are required, for as will be shown hereinafter provisions are made for doing most of the erasing above the glass door. The rear door D is hinged at D and is provided with an inclined table E, for the printed paper to rest against after it has been fed out through the aperture, and rises above the top of the casing. Other objects of thisinclined table Wlll be referred to hereinafter. In front of the inclined platform and directlyin the vis1on of the operator when sitting in a normal uprlglit position, is mounted the copyholder This copyholder, which is made in; the

shape of an open frame, is connected. to each of the two ends of the inclined table by movable links F and F which permits the copyholder to assume two distinct positions of rest. Its normal working position is shown in Fig. 2, where the links are resting on the top of the buttons F 3 and F while the obect of the second position, shown in Fig. 1, where the links rest against the other of buttons F ,isto enable the operator to readily examine that portion of the writing that is resting on the inclined table.

In order to locate the casing properly in relation to the typewriter, so as to make the paper pass out through the aperture in the top of the casing, I employ two handlesG, attached to the typewriter through a pair of openings, in the form of round holes B and B situated one at each end of the easmg. The handle at the left hand end (F ijg. 8) is attached to the squared end of the paper-feed rod 260, situated directly beyond the handle 210, as shown i i-Fig. 5 of my companion application already referred to. This handle is made to work loosely in the corresponding opening B of the casing, and enables the operator to feed the paper up'and down by hand from outside the casing. This makes it possible to bring the writing quickly above the glass door to makeany necessary corrections on the table E, and to return the paper to the printing line without opening the front door. Only in case of corrections on the last few lines of the paper will it be necessary to open the front door. This manner of erasing has the additional advantage of keeping the erasure dust away from the machine. The other handle is similarlyattached-through the opening B in the opposite end of the casing-to the squared end of the winged rod 207. This rod, as shown in Figs. 6 and 7 of my companion application, releases the paper in the "carriage, and makes this operation possible from outside the casing. While my preferred construction shows these locating handles operating the paper line feed and the paper release mechanism, I do not wish to confine myself to this particular use of such handles, as a different typewriter construction might make other uses for them more desirable.

In order to make the table E rigid to work against, the rear door D is held in locked position when closed, by means of a springactuated pawl K, fastened to the left hand end of the door. This pawl grips a hook J, fastened to the top of the casing B. WVhen opening this rear door the operator grips the .forwardly extending portion of the pawl K,

and by lifting it releases the pawl from the hook J, and forces the lower rear part of the pawl against an abutment J This transorms t e pawl into a handle for opening the door, which when opened assumes the position indicated by dotted lines in Fig. 1. It is in this open position that the paper is inserted. As soon as a new sheet has been gripped by the feed rolls, the loose end of the sheet is pushed back in between the machine and the rear wall of the casing, after which the door is closed again.

Another object of the table E is to utilize it as a means for gauging the correct position of the last printed line upon the paper, so as to enable the operator to provide for the proper margin at the bottom of the page. For as it is obviously dil'ficult to determine the position by the bottom of the sheet itself, which is usually hidden behind the feed rolls, I propose to determine this position by the top of the sheet, as it reaches the top edge of the inclined platform or table. In addition to this, one or several scored lines upon the face of the table, as indicated at E may be employed for gauging different length of sheets.

It should be understood that a table and a copyholder, such as has been here described, and supported on movable hinges, that makes it possible for them to be rigidly held in their working positions and readily moved out of the way, may be utilized to advantage without the use of a casing. This may be done by substituting for the casing an appropriate support for the said hinges, or simply by removing the front portion of the casing as indicated by the broken lines 00-00 on Fig. 2.

Having thus fully described my invention, what I claim as new and useful is- 1. The combination of a typewriter, a casing for covering said typewriter or a portion thereof, and insertable handles situated at opposite ends of said casing for locating said casing and for respectively manipulating the paper linefeed and the paper release mechanism in said typewriter from the outside of said casing.
