SCHOOL DESK AND CHAIR.

Specification of Letters Patent.

Patented Mar. 1, 1921.

Application filed September 13, 1920. Serial No. 409,777.

To all whom it may concern:

Be it known that I, Louis ARNHoLz, a citizen of the United States, residing at Wichita, in the county of Scdgwick and State of Kansas, have invented new and useful Improvements in School Desks and Chairs, of which the following is a specification.

My present invention has reference to a school desk and a chair therefor.

My primary object is to produce a desk which is vertically adjust-able upon its supporting standard, and a chair therefor which is likewise vertically adjustable upon its supporting standard, the latter being also adjustable longitudinally with respect to the desk, and whereby the desk and chair may be employed by pupils of varying sizes.

It is a further object to produce a vertically adjustable desk and a vertically and longitudinally adjustable chair disposed adjacent to the desk and elevated from the floor on which the device is arranged,the construction bein such as to permit the pupil arranging himself on the chair from either of the ides thereof, and the construction being also such as to permit of the device as a unit being swung so that the support for the chair and desk will be arranged vertically to occupy a comparatively small space when not in use and to also permit the proper cleaning of the floor'on which the device is arranged.

It is a still further object to produce an article of furniture, of this character, which shall be of a comparatively simple construction, cheaply manufactured, readilyadjusted, and thoroughly eflicient for the purpose for which it is devised.

With the foregoing and other objects in mind, the improvement resides in the construction, combination and operative arrangement of parts, such as is disclosed by the drawings which accompany and which form part of this specification.

In the drawings Figure 1 is a plan view of an article of furniture constructed in accordance with this invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a sectional view approximately on the line 3-3 of Fig. 2.

Fig. 4 is a sectional view approximately on the line 4-4 of Fig. 2.

Fig. 5 is a sectional view approximately on the line 5-5 of Fig. 1.

Fig. 6 is a side elevation illustrating the article of furniture swung to position when floor space is required, or when the floor is being cleaned.

Fig. 7 is a perspective view looking to ward the under face of the chair bottom.

Fig. 8 is a perspective view of pedestal for thechair.

The base 1 of my improved'article of furniture may be of any desired height, length and width, and is channeled longitudinally throughout the length thereof. Preferably but not necessarily, the channeled base 1 has on its sides, adjacent its corners angle brackets 2, the horizontal members of which having openings therethrough and resting on the floor on which the base is arranged, so that securing element may pass through the said openings and rigidly fix the base to the floor. The brackets, even when unattached to the floor provide stabilizing means for the base. The base at one of itsends has secured between the sides thereof an upstanding pedestal 3 which, in the present instance is rectangularand is hollow. On the end of the base provided with the pedestal there is secured one of the leaves of a. hinge 4c, the lower leaf resting on the floor and being secured thereto. By this arrangement, the article of furniture may be swung (when the brackets are not secured to the floor) to bring the base to a substantially vertical position so that the article of furniture will occupy comparatively small'floor space, when such space is needed and also whereby the floor beneath the base may be properly cleaned.

On the sides of the pedestal 3 are wear plates 5 through which centrally extend threaded studs 6.

The desk part of the furniture is of the usual construction, but has its bottom cen trally provided with a substantially rectangular opening 7 of a size to freely receive therethrough the pedestal 3. Projecting through the opening and secured to the under face of the top of the desk is a rectangular standard 8. The standard is ar ranged centrally with respect to the opening and is of a size to be freely received in the hollow pedestal 3.

Depending from the bottom of the desk, in a line with the side walls provided by the opening 7 are centrally slotted plates 9. These plates are designed to receive in the slots thereof the studs 6. The studs are engaged by nuts which bind the slotted plates against the sides of the pedestal 3, and thus retain the desk at vertical adjustments with respect to the pedestal. By having the bore of the pedestal of a rectangular formation and by having the standard 8 of a like formation, a swinging or wabbling movement of the desk on the standard will be prevented. The nuts 10 are preferably winged, so that the same may be easily ad- 7 justed on the threaded studs, and conseadjusted on the pedestal and locked at such quently the desk may be quickly and easily project threaded studs16.

The chair 17 preferably includes a bottom and a back, and on the bottom, at the center thereof there is a depending rectangularr standard 18, of a size to be snugly received in the bore 14 of the pedestal 12. To the opposite sides of the standard there are depending slotted plates 19 that are designed to pass over the wear plates on the pedestal and receive in the slots thereof the studs 16. The numeral 20 designates winged 'nuts which engage with the threaded studs I 16 and which contact with the slotted plates 19 to bind the same against the wear plates on thesides of the pedestal. The chair memher, it will be noted, maybe easily adjusted vertically on its pedestal, and the pedestal may be adjusted longitudinally on the channeled base to bring the chair near or away from the desk to suit the size and convenience of the pupil occupying the chair. The

I pupil may; arrangehimself on the channeled base from either of the sides thereof. The sides of the base are widened at the ends thereof, so that the'channel at the part thereof contacted by the feet of the pupil is comparatively shallow, the widened sides stabilizing the pedestal for the chair and the pedestal for the desk.

It is thought that the foregoing description, when taken in connection with the drawings, will fully set forth'the construction and advantages of the improvement, but it is thought necessary to add that the invention is not to be restricted to the precise structural details set forth in the foregoing description and illustrated by the having threaded studs, a member having a depending standard received in the pedestal, slotted .plates depending from themember receiving the studs, binding elements on the studs contacting the plates for forcing the. same against the wear plates and for holding the member adjusted on the pedestal, a second hollow pedestalslidable in the channeledbase, means for locking said pedestal on said base, wear plates on the sides of the said pedestal having threaded studs, a member having a depending standard received in the last mentioned pedestahslotted plates on the last mentioned member receiving thestuds of the last mentioned pedestal, and binding elements onthe studs for forcing the plates againstthe wear plates of the pedestal and for sustaining the member vertically adjusted with respect to the pedestal. In testimony whereof I afiix my signature;

LOUIS ARNHOLZ.
