Specification of Letters Patent.

Application filed June 23, 1911.

Patented Nov. 7, 1911. Serial No. 634,922.

To all whom it may concern:

Be it known that I, CHARLES A. HART, a citizen' of the United States, residing at Findlay, in the county of Hancock and State of Ohio, have invented certain new and useful Improvements in Type-Writer Desks, of which the following is a specification.

The present invention has for its primary object to provide certain improvements in that type of desks designed particularly for holding typewriters, and which ordlnarily embody a drop cabinet structure includlng a movable base on which the typewriter rests and movable top to cover the machine when the same is dropped into a compartment of the desk to be housed out of use.

The cabinet desks at present in use for typewriter purposes particularly and those utilizing the drop or swinging base and top to provide a closed compartment afford a supporting means for the base which renders the latter easy to tilt so that sometimes the machine, when in position, is accidentally dropped into its compartment and S11b160t6d to damage in the operation.

It is therefore a special object of this invention to provide a construction of parts such as above referred to wherein the movable top of the typewriter compartment of the desk, when thrown back or dropped, will swing the base into a position wherein the supporting means of the top and base wlll practically lock the latter with the machine exposed ready for use, until a suitable pull is exerted on the top to lower the base and typewriter into the compartment.

For a full understanding of the present invention, reference is to be had to the following description and to the accompanylng drawings, in which Figure 1 is a perspective view showing a typewriter desk embodying the essential features of the present invention; Fig. 2 is a transverse sectional view bringing out more clearly the positions assumed by the parts after the top and base have been moved to raise the latter into an operative position; Fig. 3 is a top plan view of the central portion of the desk showing the parts in the positions illustrated in Fig. 2; Fig. 4 is a view similar to Fig. 2 but showing the desk entirely closed to provide the typewriter compartment, which is perfectly dust proof.

Throughout the following detail description and on the several figures of the drawings, similar parts are referred to by like reference characters.

. The desk illustrated in the drawings is, in its main features, of the conventional sanitary type, but it is to be understood that the invention may be readily incorporated 1n the construction of desks of various other styles or types in so far as the general structure is concerned. As shown, the desk comprises two pedestals l containinga series of drawers each and between said pedestals is located the compartment and drop cabinet structure for the typewriter. A suitable movable top section 2 is provided, the same having a ledge 2, the latter forming a partial closure at the front portion of the typewrlter compartment. The base 3 on which the typewriter will be secured, as customary, 1s hinged or pivoted to the front portion of the desk at 3 and is adapted to swing downwardly upon inclined stop strips 9 at opposite sides of the typewriter compartment and secured to the inner walls of the pedestals 1. The top 2 is supported primarily by a pair of upper curved levers 4 and a pair of lower links 5. The levers 4 are pivoted intermediate of their ends at 4 to the adjacent walls of the parts 1 of the desk and the links 5 are pivoted at one end at 5, and at their opposite ends pivotally connected to the rear portion of the top section 2 on its under side. The levers 4 are pivotally connected at one end, as shown at 4", to the middle portion of the top section 2 on its under side, while the opposite ends of said levers are pivotally connected with links 6 at one end of the latter. Two of the links 6 are provided and the opposite ends of said links have slots 6 through which pins 7 on the base 3 pass. The pins 7 extend across slots 10 in the base 3, and the links 6 are so arranged that when the parts 2 and 3 are operated to raise the base 3, said links are virtually pendant from the upper ends of the levers 4 and the pull on the links exerted by the weight of the base 3 and supported typewriter, will be below the axis of the levers 4. In other words, the more pressure exerted on the base 3 when it is in the position shown in Fig. 2, the more firmly the base is held in its horizontal position.

Assuming that the parts are normally in the position shown in Fig. 2 when in use, should it be desired to close the typewriter compartment of the desk, it is only necessary to lift upwardly on the top section 2, imparting a pivotal movement to said top section which swings on the links 5 and levers A upwardly and toward the front portion of the desk until the upper side of the top sec tion is flush with the topsof the respective pedestals 1. The desk may then be used as an ordinary flat top desk.

When the desk is closed, as shown in Fig. 4:, the typewriter compartment is absolutely dust-proof and houses efiectively the typewriter in an obvious manner. Furthermore in the final movement of the parts 2 and 3, in assuming the positions shown in Fig. t, the pins 7 move upwardly in the slots 6 and the weight of the base 3 and typewriter secured thereto will thus be received upon the stop strips 9 which virtually form extensions of a bottom part 8 for the typewriter compartment. The initial movement of the top section 2 in order to raise the base 3, is free therefore until the links 6 begin to pull upon the pins 7 through the connecting slots 6. The arrangement and curvature of the links 5 and levers 4: are such that the lower ends of the levers and links fit together when the parts assume the positions shown in said figure.

Having thus described the invention, what is claimed as new is:

In a typewriter cabinet, the combination of a desk body having a typewriter compartment, a movable top section for said compartment, a movable base hingedly connected to the front portion of the desk body, a pair of levers connected at one end to the top section and pivoted to the desk body between the ends thereof, a pair of links connected at one end to the top section and at the other end to the desk body, lifting links connecting the base with the other ends of said levers, said levers being so curved and arranged as to raise the base when the top section is thrown downwardly into the typewriter compartment, the lifting links being arranged to support the base and to move into positions such that the connections between said links and the base, the connections between said links and the levers, and the axis of the levers are in alinement.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES A. HART.
