TABLE FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 794,594, dated July 11, 1905.

Application filed February 6, 1904. Serial No. 192,406.

To a, whom it may concern:

Be it known that l, GEORGE W. DONNING, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Tables for Type- VVriters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a combined supporting-leaf and cover for attachment particularly to tables or desks upon which are disposed fiat platen book type writing machines and which are formed with a laterallyslidable book rest or carriage. In this class of writing-machines the book to be written on is supported on an adjustable carriage adapted to traverse a path transverse of and beneath the platen or printing-surface in such a manner that the several leaves of a book may be turned over and laid upon the platen or printing-surface in position to be printed upon. To permit the printing to be done on either side of the page at will, the book rest or carriage is moved to either side of the platen, and heretofore it has been found necessary to util ize for the track or guide rails of the bookcarriage a considerable space on each side of the platen, so that when the carriage is moved to one side of the machine the space at the opposite side while not being used for the support of the book rest or carriage is rendered useless for any other purpose by reason of the tracks thereon, as well as for the further necessity of leaving it clear to permit the movement of the book-carriage for readjustment of the book. It is of course necessary to have the top of the table above the said book-carriage clear and unobstructed when it is desired to place the book thereon or remove it therefrom. Therefore in order to employ the space at either side of the platen for workholders such devices must be supported at such a height as to clear the loaded book-carriage, and, preferably, such work holders should be movable, so as to give ready access to the carriage.

It is the object of this invention to utilize these spaces for paper or copy holding devices, either one of which will give access to the carriage as the latter is transferred from one side to the other of the platen.

A further object is to provide a type-writer table with a platen located in the central portion of its top, a traveling book-carriage operatively mounted with reference to the platen and adapted to occupy either of the end portions of the top, and two movable work-holding leaves adapted to lie above such end portions at a suflicient height to clear the book and carriage.

With these objects in view the invention consists in attaching flat leaves or shelves upon the upper portion of the table or desk and arranging them so that they may be brought into position to form a substantial top to the table, covering these portions of the table adjoining the platen on either side. Each leaf is mounted, as by pivoted bearings, so that it may be swung down and be allowed to hang beside the table, the other leaf meanwhile serving to hold all the paper or copy. When the leaf is closed, it is supported at a distance above the table-top, so that the loaded carriage beneath will not touch its under surface.

In the accompanying drawings I have illustrated an embodiment of my invention, though others may of course be used.

In the drawings like letters of reference indicate corresponding parts.

Figure 1 is a perspective view of a booktype-writer table embodying my invention, the writing mechanism being omitted to avoid confusion. Fig. 2 is a view in perspective of one of the hinges of the covering-leaf detached. Fig. 3 illustrates a modification in the manner of attaching the leaf to the table; and Fig. 4 is a detached view, partly in section, of the form of support or hinge shown in Fig. 3.

In the drawings, A designates atable or support for the writing-machine, preferably supplied with drawers or receptacles a a for supplies, and having an open top A a supportingframe A, forming the edges of this table.

Over the central portion of the open top is supported aflat platen or writing-surface B, so that a page of a book placed thereon may be turned over on the writing-surface from either side thereof. Slidably disposed beneath the platen is the book rest or carriage D, upon which the book is placed, and moves to position it to one or the other side of the platen according to which side is to be written upon. It will be readily understood that during the operation of placing the book upon this carriage or of its removal therefrom provision for access thereto must be made. When, however, the book has been placed in position and while the printing is being done no such access is necessary, and therefore the space at either side of the platen may be utilized in any way desired, and to permit this I provide two fiat leaves E, pivotally connected to the table by hinges F, located at opposite sides of the leaves.

When theleaves occupy the closed position shown in Fig. 1, they form covers for the portions of the top at opposite sides of the platen; but when access to one end of the top is necessary, as for placing or removing the book or inspecting a written page, the leaf over this portion by means of its pivotal connection is swung to occupy the position indi cated by dotted lines. It will be seen. therefore. that since only one end portion of the table-top is occupied at one time by the carriage there may always be one closed leaf to serve as a paper-holder. Leaves E are supported in a plane above that of the platen, so that in shifting the carriage and book from side to side of the table, the book pages, particularly the free ends thereof, will not contact with the leaves.

The hinge F is preferably made as shown in Fig. 2 and comprises an upwardly-inclined projecting supporting-arm having an inwardly-projecting pin or pintlef, the leaf being provided with an opening, (not shown,) and the pintle f formsa trunnion upon which the leaf E may turn. Upon the inner face of the arm f, below and in front of trunnion-pin f and adapted to engage with the under surface of the leaf when closed, may be disposed a supporting block, boss, or bracket f to assist the pin to support the weight which may be placed upon it. This hinge-arm f is preferably made to extend first upward from the edge of the table A to raise the hinge-point somewhat above the table-top, and this permits the leaf to swing free of the top, and, secondly, outward to throw the hinge-point beyond the edge of the table-top to permit the leaf to be turned and dropped alongside of the end of the table.

In Fig. 1 the leaf is shown as hinged at a fixed point and is turned on its trunnion-pins, as indicated by dotted lines; but in certain instances in lieu of this construction it may be desirable to provide the edge of the leaves E with a groove or slot 6 wherein the trunnionpin f will enter, so that the leaf may be raised to a vertical position and then slid down on the trunnion-pinsf, as shown in Fig. 3. The leaves E may be hinged or mounted to be turned or moved down at the rear of the table as well as at the ends, or they may be arranged to be dropped inside of the walls of the table without departing from my invention.

The leaf E may carry a standard G at its free end to rest upon the frame A and serve to support the same above the surface of said frame and in the same horizontal plane as the hinge member F supports the hinge end of said leaf, or this standard may be disposed on the frame and the leaf rest upon it. This standard, in connection with the upwardlyprojecting arm of the hinge member, supports the leaf when closed clear of the carriage and permits both leaves to be lowered during the process of writing without interfering with the operative position of the carriage. By the expression supporting the leaf clear of the carriage I wish to be understood, of-

course, as meaning that the leaf is at a sufficient distance above the carriage as not to interfere with a book placed thereon.

What I claim is- 1. In a type-writer table, the combination with the top thereof, a platen occupying the central portion of the top, and a movable bookcarriage adapted to be positioned in the portions thereof at either side of the platen; of leaves movably mounted on the table for covering the portions of the top at opposite sides of the platen while leaving the platen exposed, each leaf being adapted to permit access to the carriage.
