Patented June 5, 1934 CHAIR Willis D. Rich, Hingham, Mass, assignor to Deskor Chair Sales Corporation, Boston, Mass, a corporation of Massachusetts Application January 23, 1932, Serial No. 588,353 In Great Britain August 16, 1929 1 Claim.

The invention relates to an improvement in chairs of a type essentially adapted for schoolroom or hall use.

The object of the invention is to provide a 5 chair of simple structure, and the seat and back of which may be adjustably raised or lowered; also, a chair structure within which may be deposited articles by one sitting back of the chair.

The invention can best be seen and understood by reference to the drawing in which Figure l is a side elevation of a chair embodying the invention, and

Fig. 2 is a vertical cross section thereof.

Referring to the drawing 20 represents the seat of the chair which is pivotally secured to a support 21 consisting of a box-like case of general rectangular form with opening at the back and comprising a top 22, a bottom 23, sides 24, and a front wall 25. The seat is hingedly secured to the top of this case by a hinged connection 27 located forward of the back thereof and preferably located about midway the top so that when the seat is in its downturned position it will extend forwardly of and rest upon the top of the case acting as a support therefor, thence with forward projection well beyond the front wall of the case; or the seat may be turned into an upright out-of-the-way position as shown in the dotted lines of Fig. 3.

The case 21 is adjustably mounted with relation to the floor so that it and the seat carried by it may be raised or lowered and fixed in adjusted position. At the front the case is mounted upon a leg 28 made in separate parts 29, 30, one slidable upon the other for increasing or lessening the length of the leg. The parts 29, 30 of the leg are fastened together in adjusted position by means of screws 31 passing through the part 29 of the leg and extending through certain ones of a series of openings 32 in the part 30 of the leg and are afterward secured by binding nuts 33 which, when tightened, hold the screws securely in place and bind together the separate parts of the leg. The part 29 of the leg bears upon its top end a member 34 on which the front edge of the case rests while the part 30 of the leg bears upon its bottom end a foot 35 which is secured to the floor. At the rear the case 26 lies interposed between a set of uprights 36, 36 arranged at the back of the chair and cornerwise in relation to its seat. The case is fixedly secured to the uprights by fastenings 37 extending through the uprights The uprights are also preferably provided with brackets 38 extending forward to lap by the ends of the case to which they are secured by fastenings 39. Each of the respective uprights is borne by an adjustable leg 40. This leg is arranged to slide upon the interior of the upright at its bottom and is fixedly secured to it in adjusted position by screws 41 passed through the upright and through certain ones of a series of openings 42 formed in the leg, and are held by nuts 43 on the screws which when tightened hold the screws securely in place and the leg bound to the upright. The leg'bears upon its bottom end a foot 44 which is fixedly secured to the floor. Thus the case 26 and seat borne by it may be raised or lowered and maintained in adjusted position with relation to the floor. V

45 represents the back of the chair which lies interposed between the tops of the uprights and is rigidly sectued thereto in any suitable manner. Preferably the tops of the uprights on the interior sides thereof are provided with sockets 46 in which the opposite ends of the back are firmly seated. The adjustment of the back for raising or lowering is secured by the adjustment of the uprights; the back, in other words, being raised or lowered with the seat.

The case 21 in addition to providing a support for the seat forms also a depository in which articles can be placed by one sitting back of the chair. 1

Having thus fully described my invention, I claim and desire to secure by Letters Patent-of the United States:

, In a chair, the combination comprising a seat, a support on which the seat is mounted consisting of a case or box-like structure with opening at the back and having a top, bottom, sides and front wall, means for pivotally securing theseat to the top of the case forward of the back thereof whereby the seat may occupy a down-turned position resting thereon with projection forward of the front end of the case or an upturned out-ofthe-way position with relation thereto, a leg support for the case at the front, a set of spaced uprights at the back to which the case is secured, said leg support and said uprights maintaining said case elevated with relation to the floor, and a back for the seat carried by said uprights and against which back the seat rests when occupying its upturned position as aforesaid.

WILLIS D. RICH.
