SCHOOL-DESK.

SPECIFICATION forming part of Letters Patent No. 673,335, dated April 30, 1901.

Application led February 20,- 1901. Serial No. 48,120. (No model.)

To tit whom t may concern,.-

Beit known that l, JOSEPH B. CAsEBoLr, a citizen of the United States, residing at Mount Sterling, in the county of Crawford and State of Wisconsin, have invented certain new and useful Improvements in School-Desks; 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.

My invention relates to improvements in school-desks; and it consists of certain novel constructions,` com binalions, and arrangements of parts, as Will be hereinafter more fully described and claimed.

One of the objects of my invention is the production of a desk which whenit is in a normally closed condition will render the compartment for books and other articles dust-tight and which when in an open condition Will bring the writing-surface into Such a position with relation to the body of the writer that he can write upon the same without cramping his arms or leaning forward, as frequently occurs with desks of ordinary construction.

Another object 0f my invention is the production of a desk having a pivoted swinging writing-surface which when swung forward will expose the receptacle for books and other articles to admit of the ready removal and insertion of such articles from the top without the user of the desk changing his position while occupying the seat in front of said desk.

Another object of the invention is the provision ot' means for guiding and steadyingthe swinging movement of the cover or writingsurface of the desk at a number of points, which prevent the twisting or lateral movement of said cover or top.

A further objectof my invention is the provision of sufficient space between the forward edge of the cover or top when the latter is in an open condition and the front vertical Wall of the body of the desk proper, so that a book can be supported and held in an open position between the said parts ofthe desk.

In the accompanying drawings, Figure lis a view in perspective of a desk embodying the features of my invention. Figs. 2 and 3 are detail views of one of the pivot-arms in side and front elevation, respectively. Fig.

4 is a sectional view of one corner of the desk, part of the desk being broken away and illustrating the means for securing the cover to the body of the desk. Fig. 5is a detail View of the locking-plate. Fig. 6 is a top plan view of my improved desk with the cover or top thereof swung to its farthest forward position, part of a chair being illustrated to show its relative distance from said desk. Fig. 7 is a view in side elevation of the desk and chair, the top or cover being in its closed position, but shown in dotted lines in its open position; and Fig. 8 is a transverse vertical section through the body portion of the desk, the cover being in an open position.

Referring to the drawingsby numerals, 1 indicates the main body or desk proper, supported by legs 2 and provided with a cover 3. The body l completely incloses the stationery and book receptacle, as 4., by four walls, forming said body. The four walls consist of two end walls, as 35 35, and two side walls, as 36 36. A suitable bottom, as 37, is also provided for completing the receptacle. The end walls are preferably formed slanting toward the front, as at 5 5, and formed intheir inner upper edges with grooves, as 6, leaving upwardly-projecting edges, as 7. The interior of said main body .forming the book-receptacle 4E may be subdivided, as may be desired, int-o two or more compartments by a strip or strips 8, and a stationary or removable ink-well, as 9, and pen and pencil rack, as 10, may be provided for the convenience of the user. H

The cover 3 of the desk is preferably formed of a top or writing surface l1, provided with a down wardly-extending flan ge, as 12,secured near the edge thereof and extending entirely around the same. The said flange 12 is preferably beveled from front to rear, corresponding in pitch to the slanting portions 5 5 of the end walls of the desk. Agroove, as 13, is formed in the edge of said beveled portions, leaving a downwardly-projecting portion 14, adapted to register with groove 6, and at the same time edge 7 will register with groove l3,whereby the cover of the desk cannot be moved laterally while resting upon said desk. The ange 12 is adapted to fit snugly the upper edges of the four walls of the desk, and thereby prevent any dust from entering the book- IOO receptacle while the cover is in its closed position. The side walls 36, if desired, may extend beyond the front wall and are adapted to support the continuation of flange 12, as at 12a, which rests upon said extensions at either side of the desk when the cover is in its open position.

I hinge the cover or top 3 to the body 1 by means of arms 15 15, which are provided at their upper ends with elongated securinglngs, as 16, extending at right angles to said arms and each provided with an annular' groove, as 17, for receiving any desired securing means, as 1S. When in position, the lug 16 extends through iiange 12 and into a strip of material, as 19, secured to the under face of top 11 and extending longitudinal of and contiguous to the end flanges 12,wherein the said lug is permanently secured by passing a nail or other desired means 18 through the strip 19 and annular groove 17. The lower end of arm 15 is provided with a lug, as 20, formed integral therewith and extending parallel to lug 16, but preferably shorter than lug 16. A locking projection, as 21, is formed on one side of lug 20, which when the parts are being assembled is adapted to pass through aperture 22 of keyhole-slot 23 in the locking-plate 24, the said locking-plate when the parts are in position being given a halfrevolution and then secured to thewall of body 1, whereby lug 2O may be securely locked within the end walls of said body portion 1.

The operation of my improved desk will be readily understood.

Fig. 7, and a person occupying the chair in front of the desk desires to gain access to the book-receptacle, he may grasp cover 3 at any point and pull forward on the same. The effect will be to cause the cover to move forward in the arc of a circle through the medium of the arms 15, of which a plurality is l may be applied at any point of said cover` without danger of lateral movement of the same.

The sanitary advantage of my improved construction will be obvious.

writing-su rface toward lhimself a distancejust sufficient to permit him to write freely without cramping his arm or bowing his back.

Another important advantage in my improved desk is the provision of the rear edge of the cover 3 when said cover is in its opened position, which is such that the edge of an open book may be passed beneath the same and above the rear and front vertical walls When the cover 3 is in 3 its closed position, as seen in full lines in r of the body of the desk, whereby the open book will be in sight of the person using the desk, who may not only read from the book, but at the same time has the full area of the cover or writing-surface to use for writing or other purposes, as desired.

Although I have described in detail one specific embodiment of my invention, yet I do not wish to be understood as limiting myself to the exact features specified, but shall feel at liberty to deviate from the size, shape, and minor details of construction of my improved desk within the scope and spirit of my invention. v

A very important feature of my invention is the construction and arrangement of the hinges or pivots for securing the cover or top to the body of the desk and permitting of the forward and backward movement of the same and at the same time preventing a lateral or twisting strain while the lid is being moved. I accomplish this by the construction heretofore set forth, but stated brieiiy, which is the provision of pivoted arms, a plurality of which is secured to each side of the desk, which arms are provided at their upper ends with long pins or shanks extending at right angles thereto. It is important that these pins be long, as it thereby prevents any possibility of a twisting,r or lateral motion of the cover or lid while in a raised condition.

It will be observed that the compartment 4 is located at the rear side of the body of the Vdesk and is arranged vertically and is made comparatively deep and that the space forward of said compartment is left uninclosed. By this construction and arrangement room is provided for the knees of the pupil occupying the seat in front of the desk, and by providing the desk with a transverselymovable cover a dust tight closure for the compartment 4 is provided when said cover is moved to its rearmost position, and when moved to its foremost position access is afforded to the said compartment from the top of the desk without further manipulation of the cover, and the cover is brought close to the pupil, which not only facilitates the use of the cover as a writing-surface, but economizes floor-space, as it enables a seat to be placed close to the desk, all of which advantages are desirable and important in a schooldesk.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is A person seating himself in front of the desk may draw the 1. A school-desk comprising in its construction a main body portion provided in its rear part with a vertically-arranged comparatively deep book-compartment, the said compartment being inclosed by end walls, side walls and a bottom, and a cover having a bodily forward-and-rearward movement so constructed and arranged that when it is moved to its extreme rear position it rests di- IOO IIO

rectly over the book-compartment and completely closes the same, and which when moved toits eXtreme forward position exposes substantially the entire length and width of the book-compartment, and affords access to the entire compartment from the top of the desk, and permits a pupil seated in front of the desk to insert or withdraw books without further manipulation of the cover, and means for retaining said cover in position.
