"FWP'IE WFHTIEW DESK,

SPECIFICATION forming part of Letters Patent No. 783,875, dated February 28, 1905.

Application filed July 9, 1903, Serial No. 16 L928.

Be it known that we, Lanna E. Luznrrsnn and Cnjns'rnn BRADFORD, citizens of the United States, residing at lndiana iiolis, in the county of Marion and State of Indiana, have invented certain new and useful IIIIPI'OVGI'IIGUtS in Type- \Vriter Desks, of which the following is a specification.

The object of our said invention is to produce a type-writer desk in which the type writer may be moved from operative to foldedup position and by the same act the working table of the desk raised from the level required for type-writing purposes to the ordinary desk-level and there held until the type writer is thrown back to position for use, when the said table will sink to its former position.

A desk embodying our said invention will be first fully described and the novel featu res thereof then pointed out in the claims.

Referring to the accompai'iying drawii'igs, which are made a part hereof, and on which similar reference characters indicate similar parts, Figure 1 is a front elevation of a desk embodyingsaid invention; Fig. 2, a transverse vertical sectional view of the same as seen when lookii'ig in the directirm indicated by the arrows from the dotted line 22 in Fig. l, and Fig. 3 an under side plan view of so much of the structure as is involved in our invention and immediately adjacent parts as seen when looking upwardly from the dotted line 3 3 in Fig. 1.

l Ve have shown our invention as applied to i the variety of desks dei'iominated roll-top i desks. Within the walls 10 of such a desk we place the table II. This table is capable of a positiolrshiifting movement, whereby it is ada 'ited to travel up and down between the rest-brackets 12 and the stops \Vhen the table is in its lower position upon the restbrackets '12, it is at the height which is con venient for typc-writing purposes. When it is forced upwardly against the steps 13, it is at the usual or convenient height of desk-tops or tables generally. The type-writer i4 is secured to suitable lever-like siiipports I5, which are pivoted at 16 to brackets 18 or to 1 suitable adjacent portions of the desk strucl ture, and the ty ie-writer can be swung from the operative position (shown by full lines in Fig. 2) to the folded-up position (shown by dotted lines therein) on said pivoted supports. \V hen in operative position, said type-writer rests upon the table 11. \Vhcn in folded-up position, it should rest against suitable stops 19 on adjacent portions of the desk structure. At the rear end the lever-arms 16 are connected by pivots 20 to links 21, which are in turn, by means of pivots 252, connected to levers 23, and these levers in turn are connected by pivots 2a to brackets 25, which are at tached to the under side of table 11.

The operation will be easily understood by a comparison of the full lines and the dotted lines in Fig. l V hen the type-writer is raised, it operates, through the supports .15, the links 21, and the levers 523, to at the same time raise the table 1.1. When the ty pe-w rite r reaches the position shown by thedotted lines, the table has by the same i'iiovement been raised to ordinary desk-top level.

The type-writer when raised moved into a chamber formed to receive it andif the raising is more than temporary can be concealed by means of an inner roll-curtain bl, which runs just within the walls of said chai'nber and just beneath the ordinary desk-roll curtain 32 or if the height of the desk permits beneath upper compartments or pigeonholes ol. said desk below said ordinary roll-curtain.

. The inner-roll curtain 3i conmletely n'otects the type-writer from dust while the desk is being used for ordinary purposes and also greatly improves the appearance of the device during such use. The plan of placing the machine above the surface of the desk instead of below permits the operative to be occupied at the same desk upon other of the various classes of work and for any length of time without being placed in a cramped position by the drop-board, which is present in those desks in which the machine drops below the surface and which :falls diagonally across the knees and precludes an easy and comfortable position at the desk when handwork is being performed.

The interior arrangement of the desk may be anything desired. It should for convenience contain shelves, pigeonholes, and drawers for the reception of stationery, books, &c. A con venient arrangement (so "far as these matters are concerned) is illustrated in Fig. 1 of the drawings.

Having thus fully described our said in vention, what we claim as new, and desire to secure by Letters Patent, is

1. In a type-writer desk, the combination, with a main casing, of a movable table forming part of the writing-surface thereof, a pair of levers pivotally mounted on said casing and pivotally carrying said table, a pivoted typewriter support mounted on the casing, and intermediate connections connecting said pair of levers and said pivoted type-writer support, whereby as the table is lowered the typewriter is deposited upon said table and as said table is, raised the type writer is removed therefrom.

2. In a type-writer desk, the combination, with the main casing, of a table forming part of the writing-surface thereof, a pair of levers pivotally mounted on the casing, a pivoted support carried by said levers and carrying said table, a pivoted type-writer support mounted on the casing, and intermediate connections connecting said pair of levers and the type writer support whereby the two will swing simultaneously and the type-writer be brought into operative position when the table is lowered, for the purpose set forth.

3. In a type-writer desk, the combination,

with the main casing, of a table having a vertical movement and adapted to support the type-writer when in its lower position and to serve as a desk-top when in its upper position, a type-writer support pivoted on the main casing and extending over said table when in position for type-writing use, and intermediate connections between said type-writer support and said table whereby the swinging of the type-writer support will produce simultaneous vertical movement of the table.

4. In a type-writer desk, the combination, with the main casing having a chamber formed in its rear portion above the level of the table to receive a typewriter when not in use, avertically-moving table forming part of the writing-surface of said desk, a pivoted support for the type-writer mounted on the casing and arranged to be swung into and out of said chamber, and intermediate connections between said type-writer support and the table whereby the table will be lowered when the type-writer support is swung out of said chamber and raised when the support is swung into said chamber.

In witness whereof we have hereunto set our hands and seals, at Indianapolis, Indiana, this 15th day of June, A. I). 1903.
