Application filed March 12, 1917. Serial No. 154,311. I

T 0 all whom it may concern:

Be it known that I, ELI. N. MoYnR, of the city of. Toronto, in the county of York, Province of Ontario, Canada, a subject ofv the King of Great Britain, have invented. certain new and. useful Improvements in.

suit the convenience of a class or removed.

entirely. Under some circumstances also it is desirable to be able to remove the desks and leave the seats or vice versa. While it is desirable that a desk and seat be held in fixed relationship when in use, it is also de sirable that the distance between them should be adjustable. Adjustment of height is also necessary for both desks and seats. Heretofore it has been usual to employ desks with slightly sloping tops, but a demand for horizontal topsis now arising, hence it is desirable to have a desk which may be adjusted to either position according to the demand. I

There is also a demand for a desk which can be used for drawing, as well as writing, which necessitates the arrangement of the desk so that the top may be considerably raised, tilted to a greater angle and provided with a ledge at the bottom.

My object is to devise a desk which will satisfactorily attain the above objects at a reasonable cost. I attain my object by means of the constructions hereinafter described and as illustrated in the accompanying drawings in which Figure 1 is a side elevation showing a desk unit and chair unit connected to a base;

Fig. 2 a plan view of the under side of the desk top;

Fig. 3 a sectional detail on an enlarged scale illustrating the adjusting means for the desk top;

Fig. 11. a" plan view ofth'e desk. and. chair in position. on the base, showing also. the? inkwell attachment.

In the drawings; like numerals of. refer? ence indicatev corresponding parts in the dif.-- ferent figures.

The equipment: includes a desk unit: I, a chair unit 2 and usually a. base unit 3; to: which the desk and chair are removably con-- nected.

The base is formed of hollow side members 4, suitably braced, together. Key hole slots 5 are'formed in the upper sides of'thesei being adjusted to or from one. another.

Preferably, however, the desk unit is lockedv in position and pivoted latches 8 are provided for this purpose, (see Fig.6), the

chair unit being readily movablein its slots so that the user may easily adjust the position of the seat or chair to suit his requirements.

To facilitatethe sliding of the base. on

the. floor blocks or gliders 43 of hard smooth.

material are inserted into the under side;v of each side member 4, (see Fig. 8).

The legs of the chair are divided, the upper parts 9 of the legs being suitably braced together by the cross braces 10. The

upper parts 11 of the legs are adapted tov slide within the lower parts 9 and are also connected by cross braces 12. Preferably" both the parts 9 and 11 are formed of metal angle bars as shown. Bolt and slot connections 13' provide means for clamping the parts together with the chair seat at any de-- sired height within the limits'of adjustment.

The seat, it' will be noticed, is curved only in a direction from the. front. to the back not crosswise, and. thus meets" modern re quirements. The back 14 of the chair is also but slightly curved, this feature also meeting modern requirements.

Between the upper parts of the chair legs a book drawer 39 is adapted to slide.

The sides 15 of the desk are preferably formed of T angle bar members connected by plates 16 and 17 welded thereto. Between the sides is suitably secured a book receptacle 18 of any suitable material. If of metal, its ends may be spot welded or otherwise secured to the inner plates 16. This receptacle is provided with a hinged cover 19. l

- A wooden cross brace 10 connects the opposite sides of the desk and is secured in place by bolts 41 passing through the plates 16 and set up by nuts 42, holes being formed in' the cross brace to receive the nuts as shown in Fig. 3.

The desk top 20 is preferably formed of wood and has depending arms 21 of metal secured thereto. These arms fit outside of and close to the outer plates 16. Each outer plate 16 has a vertical series of holes 22 formed therein, each hole having an are shaped slot 23 concentric therewith. The depending arms 21 have at least one pair of holes 2% formed therein, though, for purposes which will hereafter appear, a series of such pairs of holes are provided, two holes of each pair being spaced apart a distance substantially equal to the distance between any one of the holes 22 and the arcshaped slot concentric therewith.

A U-shaped pin 25 is provided adapted to pass through any of the pairs of holes 24. One leg of the pin will also pass through one of the holes 22 and the other leg through a corresponding arcshaped slot 23. The desk top may thus be t'lted from either of the positions shown in Figs. 1 and 4 to the position shown in Fig. 10 to enable the pupil to stand up between his desk and chair.

To adjustthe desk top to any desired height, the U-shaped pins are removed and re-arranged with any other of the holes 22 and its arc-shaped slot 23. It is preferable not to change the position of the pin relative to the arms 21 as this would vary the are through which the desk top would swing, which is not desirable.

The purpose of having a plurality of pairs of holes 22 is to enable the top of the desk to be adjusted for use as a, drawing table. For tl1s purpose I provide a pair of concentric slots 26 toward the forward upper corner of each outer plate 16, these slots being spaced substantially the same distance as the pairs of holes 24. lVhen the desk top is to be used for drawing purposes, the U-shaped pins 25 are passed through any suitable pairs of holes 24 and through the concentric slots 26. The top may then assame the position shown in Fig. 5 or may be swung forward out of the way when the pupil desires to stand up.

It is preferable to provide one of the ends of each U-shaped pin with a wing nut 27 threaded thereon by means of which it may be secured in place.

lVhen the arms 21 swing rearwardly to the limits of the arc-shaped slots 23, the

desk top will be slightly inclined as shown in Fig. 1, this being the position now commonly employed. There is a growing demand, however, for the flat top desk, and this I can obtain'by providing a removable stop or stops limiting the rearward swing of the arms. I show for my purpose a pin 28 passing through both plates 16 at one side and adapted, when projected, to be engaged by the rearward edge of one of the depending arms 21, (see Fig. 4). To prevent this pin being removed and lost, I provide it at its outer end with a projection 29 and suitably slot the outer plate 16 for the passage of this projection. A round hole, however, is formed in the inner plate 16 so that the pin cannot be withdrawn by pulling it inwardly. A nut 30, or other suitable means by which it may be handled, is fixedly secured to its inner end so that it cannot be removed by the pupil. This pin or stop 28 is thus easily projected or retracted at will to allow the desk top to swing to the position shown in Fig. 1 or to be retained in the position shown in Fig. l.

When the desk top is to be used as a drawing table it is necessary to provide its lower side with a ledge. For this purpose I provide a removable strip 81. This strip normally rests flat on the slides 32 movable in guides 33 secured to the under side of the desk top. These slides are connected by cross bracing 3i so that they will move together. Their outer ends are turned up to form the hooks 35 to engage the strip 31.

A. coil spring 36 connected to the under side of the desk and to the cross brace tends to draw the slides to grip the strip 31. Inwardly projecting pins 37 are formed on or secured to the hooks 85 and are adapted to enter holes in the edge of the strip to retain the strip in the position shown in Figs. 1, 4- and 9. Another set of holes, see Fig. 9, is formed in the under side of the strip so that the strip may be turned. up to the position shown in Fg. 5 and retngaged by the pins 37. This strip is easily released at any time and reset by pulling out the slides 32.

As the desk top is movable it cannot be readlly equipped with an ink well, and I therefore provide a swinging arm 44 adapted at its outer end to receive the ink well 45 and pivoted at its inner end on a bracket 46 suitably secured to one of the plates 16 as shown.

From the above description it will be seen that I have devised constructions which satisfactorily answer the following requirements which experience has shown should be met by school seating and desk equipment.

The desk and seat may be used independently or as a double unit connected to the base.

The desk and seat may be adjusted to and from one another.

Both the desk top and chair may be adjusted in height.

The desk top may be used either level or slightly sloping, and it may also be raised and given a further inclination for use as a drawing table.

The top of the desk swings forward out of the way to enable the pupil to stand up between the desk and chair, thus avoiding the necessity of using a hinged seat, and enabling me to place a book drawer beneath the seat.

A book receptacle is provided in the desk, which is readily accessible when the desk top is swung forward.

l/Vhen the units are employed connected to the base, they may be moved around to meet the requirements of the class. They are also easily moved to one side to enable the room floor to be properly cleaned.

l/Vhenever the school room is required for meetings or social gatherings, the floor may be easily entirely cleared and chairs substituted or the desks removed and the seats retained.

In up-to-date educational establishments,

' the pupils to assemble in groups or to have their seats moved around in various arrangements, and to this my seat and desk equipment readily lends itself.

It will be noted that in my construction the entrance of the pupil may be from either side of the desk, which is not possible with combined chair and desk units at present on the market.
