FREDERICK P. HARRIS, OF CLEVELAND, OHIO.

TYPE-WRITER DESK AND THE LIKE.

naomoo.

Application filed May 2, 1913.

To all whom it may concern:

Be it known that I, FREDERICK P. HARRIS, a citizen of the United States, residing at Cleveland, county of Cuyahoga, State of Ohio, have invented certain new and useful Improvements in Type-Writer Desks and the like, of which the following is a specification.

My invention relates to typewriter desks and the like, and its aim is greater serviceability and convenience in such articles.

Typewriter desks, tables, and the like are ordinarily made with means for mounting and supporting the typewriter and for more or less inclosing it in the desk so that it may be out of the way when not in use, such means being in part movable to open up and expose the typewriter for use and usually including a typewriter platform or carrier shiftable to bring the typewriter from within the desk into convenient position for use, and vice versa, and also a movable cover or the like for protecting and concealing the typewriter when in the desk. The means in question, including the portion of the desk involved, is very commonly known as the typewriter cabinet. While such typewriter desks usually have drawers for containing stationery, papers, etc, these drawers are not as convenient as is to be desired in view, for example, of the variety, and number of sheets of typewriter and carbon paper often required for a singleletter.

In accordance with my invention, 1 provide the typewriter desk, table, or the like with a cabinet or the like for containing stationery, papers, etc., which is intended to be in a position above the top of the desk where its contents will be conveniently accessible when the typewriter is to be used and at other times to be in a different position where it will leave the desk with a clear, free top surface, so that the desk may be capable of the fullest use as a table. This stationery cabinet or case may be arranged to descend from its position above the top of the desk to an out of the way position below the same. For moving the case I provide operating means connected with a moving part of the typewriter cabinet means in such a way that the case is brought into the position first above mentioned when the typewriter is being opened up, and vice VGISQ T have hereinafter described illustra Speeification of Letters Patent.

Patented Dec. 5, 1916.

Serial No. 765,062.

tive embodiment of the invention in which the typewriter cabinet means comprises by way of cover a movable desk lid that when closed overlies the typewriter, and in which the case is within the desk when in its out of the way position and moves up and down through an opening in the top thereof; but while the invention extends even to specific features and details of this embodiment, it is not confined thereto.

Various advantages obtainable through or in connection with my invention will become apparent from the following description, while its scope will be indicated in my claims.

In the accompanying drawings, Figure l is a perspective view of a desk constructed in accordance with my invention, the lid being open and the cabinet in elevated position. Fig. 2 is mid-section through the portion of the desk where the typewriter is to be located, showing the operating mechanism oi the desk lid and also that-by which the cabinet is raised and lowered, a portion of the desk being broken away in order that some of these parts may be visible and certain parts being for the same reason omitted,the desk lid being closed. Fig. 3 is a similar view, the desk lid being open. Fig. 4 is a sectional view at right angles to Figs. 2 and 3, the desk lid being open.

As will be seen from Figs. 1 and 2, the typewriter desk shown is of an ordinary type in which the typewriter space is at one end of the desk and the other end contains drawers. As will also be seen from these figures, the stationery cabinet 1 is arranged at one side of the typewriter space, at the end of the desk where the drawers 2 are located, the drawers being made somewhat shorter than usual in order that there may be space for the cabinet behind them when the desk lid 3 is closed. The desk lid 3 and the movable table or platform .L to which the typewriter (not shown) is to be secured may be mounted, arranged, and connected in any well known or approved manner, the most common practice being for them to move interdependently and both swing vertically in the typewriter space.

As shown, there are a pair of links 5 pivoted to the lid 3 near its front edge at 6 and to the walls of the typewriter space near the top of the at, t, and thereare also a pair of matters pivoted to brackets on r lid near its rear edge at 9 and pivoted to the walls of the typewriter space somewhat lower down at 10. In opening and closing, the lid 3 swings on these link members 5 and rocker members 8. As for the typewriter platform 4, it is secured to a pair of brackets 11 which are pivoted at 12 to the front leg posts at opposite sides of the typewriter space, and to these brackets 11 are pivoted at 13 links 14 which are in turn pivoted at 15 to the lower arms of the rockers 8. WVhen, therefore, the lid 3 is. swung downward into the position shown in Figs. 1 and 3 the typewriter platform 4 swings up into the position shown in these same figures, and when the lid 3 is swung up to the closed position shown in Fig. 2 the typewriterplatform 4 swings downward beneath it into the position shown in that figure, and the typewriter on it is thus shifted and inclosed within the desk. To balance the weight of the typewriter and facilitate the opening of the lid 3, etc., a counterbalance spring 16 may be connected between one or both of the brackets 11 on which the platform 4 swings and the adjacent wall of the typewriter space so as to be compressed when the lid 3 is closed and expand when it is opened. Buffers 17 are also provided to cushion the lid as it comes to rest in the position shown in Figs. 1, 3, and 4.

Referring, now, more particularly to Figs. 2-, 3,and 4, it will be seen that the cabinet 1 is arranged to move up and down to one side of the plane of swing of the desk lid 3 and the typewriter platform 4, and that when raised it is at the right of the typewriter space with a convenient surface in front of it for assembling typewriter paper and carbon paper, etc. The cabinet 1, is shown as opening at its front side, so that the sheets can be drawn from its shelves of pigeonholes and assembled with the utmost convenience and despatch, and as being fully opened and exposed by the mere act of raising it. As shown, the cabinet 1 is raised and lowered by means of a lazy tongs or Jacobs ladder 20 operatively connected with the lid 3 through a. connection comprising certain parts of the typewriter cabinet mechanism above described. 7 As will be seen from these figures, and particularly from Fig. 4, the upper end of the lazy tongs 20 is pivoted at 21 to a pair of brackets attached to the bottom of the cabinet, and the ends of the lower links 22 and 23 of the lazy tongs are pivoted at 24 and 25 to adjacent crank arms 26 and 27 respectively. The crank arm 26 is mounted andsecured on a hollow shaft or sleeve 28, and the crank arm 27 is mounted on a shaft 29 fitting snugly but not tightly within the sleeve 28, these parts 28 and 29 having their bearings in brackets 30 and 31 secured to the'bottom 32 of the desk and extending i from the typewriter space' beneath thecabi-.

net. On the other ends of the sleeve 28 and of the shaft 29 respectively are mounted and secured apair of crank arms 33 and 34, and to these crank arms are pivoted at and 36 the ends of links 37 and 38 whose other ends are at 39 pivoted together and to a short link 40 which is in turn connected to the lower arm of the right-hand rocker 8 above mentioned by means of the same pivot 15 by which the link 14 is pivoted thereto. The result of this arrangement is that when the desk lid 3 is opened up and the typewriter raised into position for use the lazy tongs 20 are extended and the cabinet 1 is raised above the top of the desk, and that when the lid 3 is closed the cabinet 1 sinks down till its top is flush with the top of the desk and it is completely inclosed therein.

The cabinet 1 may advantageously be guided in its up and down movements by brackets 42 attached to its bottom and having downwardly extending arms with portions adapted to slide between ways 43 on the opposite walls of the cabinet space or recess within the desk. To balance the weight of the cabinet 1 and facilitate its operation, a spiral counter balance spring 44 may be employed. As shown, this spring 44 is arranged beneath the desk and is anchored by a bracket 45 secured to the bottom 32. The free end of this spring is con nected to a rod 46 at 47, and the ends of this rod are connected by flexible cables or cords 48 and 49 with the brackets 42. As shown, the front cable 48 passes first around a pulley 50, then back around a pulley 51, up through a hole in the bottom 32 and over pulleys 52 and 53, and finally down to a fastening 54 on the left-hand bracket 42, while the rear cable 49 merely passes first around a pulley 55 behind the pulley 50 and then directly up over a pulley 56 and another pulley (not shown) behind it and down to a fastening 57 on the right-hand bracket 42. When the'cabinet 1 is raised by the opening of the lid 3, the spring 44 will contract and aid in the rising movement, and. when the cabinet 1 is lowered the sprin 44 will be extended and so cushion the descent.

As the cabinet 1 is moved positively both ways by the operating means above described and is accurately guided in its m0vement by means of the brackets 42 and their ways 43, there is practically no chance for it to stick or become jammed.

There is no difiiculty in avoiding interference between the case and any of the moving parts of the typewriter cabinet, for the movement of the former takes place entirely outside the range or scope of movement of the latter.
