TOHCLZZ whom it may concern.- I

Be it known that I, VICTOR BE' 0111), a subject of Her Majesty the Queen 0 Great Britain, residing at Tara, in the cou ty of Bruce, Province of Ontario, Canada, ave invent ed certain new and useful Im vements in Desks'and Seats; and I do hereb declare that the following is afull, clear, (1 exact description of the invention, such will enable others skilled in the art to w tains to make and use the sam This inventionrelates to de therefor primarily intended f schools, but which are equally other uses. v

One object of the invention i to provide a desk which may be quickly and i sily adjusted in both a vertical and a 1101 ontal plane and one which may also be entirely removed from the floor when necessary.

A further object is to provide a seat which may be adjusted vertically to meet the requirements of the occupant an' which may also be adjusted horizontally bring it at any desired angle to the desk I which may be swung around beneath the sk, so as to be out of the way.

A further object is to provide efficient means for securing the i justed position, and, finally, th provide an adjustable desk a shall be compact, convenient, few parts, the whole being simpl tion, easy to operate, and econoi I facture.

To these ends the invention c l improved adjustable desk and s ed and combined substantially illustrated and described, and fi in the appended claims.

Referring to the drawings, i lar letters of reference refer to in all of the views, Figure 1 is a tral section of the improved ad and seat, the seat and its suppo the use of plicable for simple and skin its adobject is to seat which hereinafter ally defined I stable desk ing-bracket being shown in elevation. Fi 2 is an enlarged view, partly in section, howing the means for locking the desk in its dj usted position. Fig. 3 is a top View thereof. Fig. 4 is a rear elevation showing the seat folded and swung around beneath the desk. Fig. 5 is an under view of the base of the desk support, showing the detachable securing means.

In the drawings,,A represents a desk, of any ordinary or preferred construction, sup ported by a rod A, rigidly fixed to the under sidethereof. This rod A is adapted to be vertically and horizontally adjusted within a hollow supporting-standard B, the upper portion of which is provided upon its exterior with an ordinary screw-thread Z). About midway of the standard B is an annular shoulder (2, above which .the standard is turned true, so as to aiford a bearing for the seatsupport F, as will be hereinafter described. The bottom of the standard 13 is formed into a broad circular base B, upon the inner rim of which is provided a series of inwardlyprojecting lugs b which are adapted to engage with the flanges b formed upon the periphery of a base-plate O, whichis adapted to be rigidly secured to the floor. The flanges b are intercepted at suitable points by the recesses 71, which when brought into alinement with the lugs b permit of the engagement and the disengagement of the standard with respect to the base-plate, thus permitting the ready placing and removal of the desk and seat, which is a very important and desirable feature where large numbers of desks are in use and where it is sometimes necessary to remove the same, as in the case of large halls or school-rooms, in which the floor-space is occasionally needed for other purposes.

Upon the threaded end of the standard B is applied an interiorly-threaded binding-nut D, the upper portion of the interior of which is chambered for the reception of the clamping-dogs E, whose inner faces are curved to conform with curvation of the supportingrod A and toothed or serrated upon said innor faces to permit the firm clamping of the said rod A. The clamping-dogs E are recessed back of their clamping-faces to receive the end of the supporting-standard B in case it should project too far up within the hinding-nut D. The upper and outer faces a of the clamping-dogs are inwardly beveled or inclined to correspond with a similar bevel or inclined surface d upon the upper face of the recessed portion of the binding-nut D.

2 senses By means of this construction it will be seen that when the binding-nut is turned down-the inclined or beveled surfaces dwill coact with the corresponding beveled surfaces e of the clamping-dogs to force them into engagement with the supporting-rod A. A reversemovement will of course release said clampingdogs from their engagement with the supporting-rod A and permit the desk to be: raised or-lowered vertically-and also to be re volved around in either direction in a hori zontal plane. l

About the bearing F of the supportingstandard B is rotatably sleeved the seat-sup port F; so as to rotate freely thereon. A lug f projects from one side of said support, which is slotted to receive the downwardly-extending serrated arm g of the seat-bracket G, said arm g being adapted to mesh with the serrat'ed face f of the slotted lug f. The slot or recess in the lug f is of greater width at the bottom than at the top; which provides space in which to swing the arm g from engagement with the serrated face f of the slotted lug' f when'it is desired to vertically adjust the seat. The bracket G is curved; downwardly and then outwardly and upwardly from thearm g, and to the outer and upper endg of the bracket is hinged the seat portion 9 At a suitable point upon the bracket G; is fixed the upwardly extending support H of the back-rest H, which issuitably constructed and located to best subserve its intended purpose.

In viewof the explicit description above given it is believed the operation of the "va-' rious features of the invention will be readily understood without further explanation.

While I have herein shown a preferred form of carrying my invention into efiect, yet

I do not desire to limit myselfto such. pre: 1 ferred details of construction, but claim the 1 right to use any and all modifications thereof I which will serve to carry into eifect the objects to be attained by this invention in so far as such modificationsand changes may fall within the spirit and scope of my said invention. v

' I claim Q 1. A oombinedadjustable desk and seat,- comprising a tubular standard; a desk provided with a supporting-rod adapted to be ad justably sleeved within said tubular stand- ?ti'rd; means for locking said rod in its adjusted position; a shoulder formed on said tubular standard; a bearing arranged above said shoulder; a seat-support loosely sleeved about said bearing; a recessed lug integral wit h said seat-support','and having upwardlyinclined serrations upon its inner face; a seat- 1 bracket having at its inner end a depending arm,,and provided with:downwardly-inclined serrations adapted to engage with the serrations of said lug,.aud a seat portion pivoted to the outer end; of said seatbracket, substantially as described. I I

2. A combined adjustable'desk and seat, comprising a tubularsupporting-standard; a desk provided with a supporting-rod, adapt-- ed to be adj ustably sleeved within said tubular standard;: means for locking said rod in its adjusted position; a seat-support loosely sleeved upon said tubular standard; a seatbracket adj ustably mounted in said seat-support; means for locking said seat-bracket in its adj'ustedposition; a series of inwardlyprojecting lugs arrangedv upon the interior of the base of said tubular standard; a base plate provided with an annular flange intersected by radial slots, which are adapted to a receive. and release said lugs upon the rotation ofsaid standard, substantially as described. t

. In witness whereof I have hereunto set my lhandin the presence of two witnesses.
