To all whom it may concern:

Be it known that we, ALBERT L. BAN- cnor'r and GEORGE H. BANOROFT, citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of Cali fornia,have invented new and useful Inipro vements in School Desks and Seats and other Furniture,of which the following is a cation.

An object of this invention is to provide an extremely light and economical construction ads ted for adjustable school furniture and the ike.

Further objects are minimum occupation of space for storage and transportation, maximum strength, rigidity, and unbreakableness, ready and easy putting together from knockdown form, and convenient adjustment to. desired height. By this invention we secure in each and every desk complete adjustability from the lowest to the ighest, and vice versa.

Another object is to provide a construction whereby school and other furniture can be manufactured from stock materials without a special manufacturing plant.

We propose to rovide for the manufac ture of furniture w ich will supply the place of all the various sizes of school-desks and seat-standards and to do this from stock material by the use of only one set of rolls and dies, which may be applied to the standard machinery in an r plant adapted for working sheet metal, an therefore to dispense with the necessity for the numerous sets of patterns of diiferent sizes now required for the castings of the usual form of desk.

A further object of this invention is to pro vide a desk which may without any change specifi port be constructed as a horizontal-top or as a slanting-top desk.

A further object is to provide a desk the top of which may be used as a dcsk t-o or as 1 an easel, a book-rest, or a drawingioard. This is accomplished by means of a slidin member of special construction, which be fully described in the following specific-a tion.

.Thns in Fig. I the desk-stand of a elect or stri grooved in its top and having a front wallet greater height than the rear wall. in this description the front of the desk is understood to be that ortion of the desk which is farthest from t is person sitting at the desk.

A further object is to provide a cheap and convenient adjustable foot-rest for the per son using the desk and seat.

A further object is to provide a new type of dcsk which will present a novel ornamentel appearance.

7 The accompanying drswings illustrate the invention as applied to school furniture.

In the drawings different ard embodying our invention forms of standarereprcsented.

ards are indicated in a general way at 1, while 2 designates the seat-standard. In Fig. VI, 3 designet-es a modified form of desk-standard, and i a modified seat-standard.

A novel feature of our invention consists in a standard for furniture formed of corru- A furtherohject is to provide an improvement in desks by forming at the front edge thereof a combined stop and pen-and-pencil rack made of one or more pieces in the form ated sheet material. We propose to'comhinc stren th, rigidity, lightness, compactness, simp city, and great adjustability by constructing the standards of our novel fur niture from corrugated sheet material appropriately formed for the purpose.

Referring first to the form shown in Fig. I, the characters 5, 6, and 7 designate three sheets of bent sheet metal, the same being desirably corrugated and perforated. The perforations 8 9 may be of any form perferred by the constructor or user and may be of any determined length. The perforations 9 are desirably oblong slots arranged with stops 1() between them, which are of less vertical length or height than the length of the slots 9. The sheets are slidingly fitted together, and slots of engaging sheets register with each other.

11 designates bolts through the slots 9 for adjustably fastening the sheets together. The form of corrugation may be varied from a rectangular or box-plait form to an acute or obtuse bend or may be in wavy lines. All this will be readily understood. by any one versed in the art, and no illustration of the numerous forms in which the corrugations maybe made is attempted.

Preferably the corrugations of the different sheets or members are formed to correspond with each other, so that when assembled with their ends overlapping each other the corrugations willintcrlap-that is, those of one member will fit in or slide lengthwise upon those of the other member, and thereby mutually support and brace each other and also tend to prevent the cdgewise movement of the sheets upon each other with the bolts or fasteners as a center.

By making the slots of greater length than the steps 10 between them complete adjustment is secured. A suflieient adjustment of the furniture as to height may be secured by the use of only two sheets, and in some cases it is necessary to employ a greater number of sheets. Said sheets overlap each other, and where three sheets are used, as in Fig. I, the upper sheet 5 will overlap on the outside of the next lower sheet, which in Fig. I is a splicer 7, and. the sheet 7 overlaps on the outside of the next lower sheet 6, so that the outer face of the standard is free of any ledge formed by overlapping edges.

The splicer 7 in the form shown in Fig. I overlaps the base-sheet 6 and is adjustably secured thereto by bolts. In order to provide for further rigidity and also to provide for connecting the standards to the parts with which they are to be connected, said sheets 5, 6, and 7 are bent to form flanges.

12 designates a base-flange for the bottom of the basesheet 6 for the purpose of securing the same to the floor.

13 is a vertical flange which extends up along the front edge of the sheet 6.

14 and 15 are like vertical flanges on the front edges of the sheets 7 and 5, respectively.

16 designates a flange at the top of the i top sheet 5, by means of which the said sheet may be fastened to the under side of the desktop member 17.

18 designates screws by which the flanges 16 may be fastened to the desk-top member 17.

In order that the desk-top member may be inclined and yet be of uniform thickness and the flanges 16 be at right angles to the upright standard, wedge-shaped cleats 19 may be interposed between the flanges 16 and the desk-top member 17, the thicker end of the wedge being at the front and the thinner edge being at the rear of the desk. Desirably the screws 18 will pass through the flange 16 into the wedges 19 and may extend up into the top member 17, as indicated in Fig. VII.

20 designates a brace formed of a sheet of material bent at each end to form flanges 21, which may be fastened by bolts to the sheet-metal standards 1.

23 is a shelf member, desirably formed of sheet metal downwardly bent and perforated at its ends to form perforated. flanges 24, two of which are fastened to the side standards 1 by bolts 25, and the other may be fastened to the front member or brace 20 by a bolt 27. The downturned flanges 24 afford a secure means for fastening the shelf member 23 to the standard and to the front bracket member 20 and are out of the way of the books which are to be placed on the shelf, and by this arrangement the fastening belts or screws are also out of the way of said books.

Desirably the portions of the standard along which the rows of slots or perforations are arranged are flat-faced, as shown at 28, for giving a true seat for the head of the belts or screws which fasten the parts together and also to add to the ornamental appearance of the standards.

The brace 20 is arranged for closing the space between the front edges of the desk-top member and shelf member. Said space may be fully or partially closed, as desired. In Fig. I the brace 20 is shown as closing the space partially. 30 designates bracket extensions fastened to the edges of the standards, respectively, for supporting the rear portion of the top member. 31 designates foot-pieces fastened to the rear edge of the lower end of the standards to rest upon the floor and give additional rigidity to the standards. These members 30 and 31 are constructed of bent sheets of material desirably corrugated and provided with flanges 32 and 33, respectively. When said parts 30 and 31 are formed in pieces separate from the body portion of the standard, said standard may be made with straight longitudinal edges and manufactured more cheaply than if formed all in one piece.

The corrugations of the sheets which are the dos or the standard of the. seat.

secured together for vertical adjustment are of a determined depth requisite to give the necessary rigidity against lateral fiexure,and the corrugations of the bracket and foot extensions are of desirably less depth than the corrugations of the standards in order to give greater strength to resist edgewise flexure of said extensions. This will be understood by reference to Fig. VIII, in which the corrugations 70, 71, and 72 of the bracket are shown of decreasing depth from the standard toward the back of the desk.

The top and base sheets 5 and 6 of the standards are bent, respectively, to form horizontal flanges 16 and 12, respectively, for the urpose of fastening said top and base members to the desk-top 17 and the floor, respectively.

34 is a footrest formed of sheet metal bent upon itself to give ri idity and to afford an easy so )port for the foot of the occupant of k. This foot-rest is adapted for adjustment to either the standard of the desk In Fig. l the foremost desk of a row of desks is sup used to be shown, other desks of the row eing emitted from the view, and the footrest 3d is shown fastened to the desk-standards by bolts 35. A foot-rest of corresponding form is also shown attached to the standard 2 of the seat. It is to be understood that the length and other dimensions of the foot-rest may be varied to fit the space in which the foot-rest is to be mounted and that the footrest for the desk may be longer than that on the seat-standards. Said foot-rest has an oblique rear face and may be bent at its uper edge to form an eye 36 and also bent to orm a ledge 37 at the bottom, as shown in Fig. IV. 38 designates perforations through which the bolts 35 may be passed to fasten the foot-rest to the standards.

By the construction shown the article of furniture,whether a desk or seat-standard,has two points of support a b for the foot-rest 34.

' Desirably the foot-rest for the desk may be provided with flanges 39, through which the fastening-bolts 35 may be passed to enter the oblong slots 9 of the standards.

40 is a channel in the top of the desk, and 41 a slidin member in said channel top furnished wit hinged leaves 42 and 43, said leaves being hinged to a member 44 and which extends from the back to the front of the desk. Said member 44 is desirably constructed of soft Wood to form a drawin board, and the members 42 and 43 are her finished to form the top of the desk when in ordinary use. 45 designates hinges connecting members 42 43 to the sliding member 41. Said hinges may be (if-flexible materialsuch as canvas, leather, or the likecovering the entire edges of the members, as indicated at 45, Fig. V, or they may be of any other suitable construction. One of the members, as 42, may be of greater length than the other and adapted to as an easel when said member is raised at one edge for the purpose. This adjustment of said member is to be un derstood without illustration. The other member, 43 ,is desirably of loss length and is furnished with a ledge 46 and is adapted to serve as a book-rest. Said ledge 46 is desirably a cleat having a longitudinal groove 47, and its top is adapted to serve as a pen and pencil rack for the desk when the sliding member 41 is in its usual position, which it is to be understood is the reverse of that shown in Fig. I.

48 designates two grooved cleats corresponding to the cleat 46, fastened to the desktop at the opposite sides of the channel 40 to form extensions of the pen and pencil rack 46 when the sliding member ll is arranged for using the desk as an ordinary school-(lbsk.

. Desirably the channel 40 is located nearer to the right side the desk (as clearly shown in Fig. IX) than the left, this being the most convenient arrangement for use of the upil when the sliding member is used as a rawing=board, book-rest, or easel.

The side Walls of the channel 49 are desirably vertical and the removable sliding mem ber 41 desirably fits snugly therein and can be withdrawntherefrom vertically and can also be slid therein in order to adjust it in either direction. When it is desired to use the easel, the hinged member 42 will simply be raised at its rear edge and propped up with books or any other suitable sup ort, and thus held at a desirable angle. T 1e sliding member may he slid forward to bring the rear edge of the sliding member 41 forward from the rear edge of the channel portion of the desk-top 1'1 to form a ledge to support any article placed on the easel.

To use the book-rest, the sliding member 41 will be Withdrawn from the channel 40 and reversed end for end, and the leaf 43 will be raised to an appropriate angle, where it may be propped up by books or other articles. The cleat 46 forms a convenient ledge upon which the book or other article may rest. The user may slide the member it forward or back to bring the book-rest to a desired position.

To use the sliding member 41 as a drawingboard, the same may be inverted, and if desired to give the same a greater slant than that of the desk-top the cleat 46 may be allowed to rest on the floor of the channel 40 at the front of the desk. If it is not desired to give it a different angle than the desk-top, the member 41 may be adjusted forward sufficiently to allow the cleat to come in front of the front edge of the desk-top, or said member 41 may be placed in position with the cleat 46 behind the rear edge of the desk.

The front walls 6 of the grooves in the tops of the cleats 46 and 47 are higher than the rear walls f, so that pens and pencils may be easily put into the grooves by the pupil sitting at the desk, and there will be no liability of pushing the same out forward over the front of the desk.

In Fig. VI a form of construction different from that shown in Fig. I is illustrated, the intermediate portion of the desk-standard being narrower than in I. The top member 50 may be formed of a single piece and the base member 51. of another piece. These two pieces may be duplicates of each other and interchangeable The slots 52 in these members are shown of greater length. than the slots 9 in Fig. I. The book-box 53 is shown as constructed independentlv of the standards. It is to be understood that the members 50 and 51 are provided with flanges (hidden in Fig. VI) which correspond to the flanges 16 and 12. (Shown in Fig. XII.) The standard. 4 of the seat (shown in Fig. VI) may be formed of two corres onding members 54 and 55, provided wit slots 56 and fastened together by bolts 57. Said members are desirably made of sheet metal bent along the body, as shown in Fig. XI, and bent at the lower end to form flanges 58, the same being perforated, as shown in Fig. XI, to receive the floor-screws 59.

60 designates screws through the flanges 58 of the top member 54 to fasten the same to the seat-piece 6].

The desk-stamlard 3 is shown as formed of two intermediate members 0 and d, fastened together and respectively fastened to the top and bottom members 50 and 51 by means of bolts.

It is to be understood that double horizontal rows of bolts may be used wherever desired for increased strength of fastening for the standards. The corrugations in the sheet-metal standard have the effect of producing a lateral extension of the bearing area against the floor and top piece. Even in case there were no end flan es at top and bottom the corrugations wouFd give sufficient width of bearing on the floor to afford a stable support; nor does this advantage disappear when the flanges are used, as the corrugations serve to give a stiffenin or bracing effect to the flanges, so that while the efective bearing width of the flange extends the full width of the corrugations the unbraced portion is only that part that extends beyond the corrugations. Furthermore, the corrugated ends of the sheet metal form a zigzag line, which construction provides for a greater length of edge for attachin the flange than would. be afforded by a standard having a straight base. This construction secures the desired strength by the use of thinner material than could be used were it not for the cooperation of the corrugated and the flanged portions of the standards, because a thin flange of great length along the line of union with the base is equal in stren th to a thicker flange of less length along sai line.
