Dec. 29, 1931. D. G. ANDERSON TABLE DESK Filed Oct. 21, 1929 fig Patented Dec. 29, 1931 UNITED STATES PATENT OFFICE DANIEL G. ANDERSON, OF LOS ANGELES, CALIFORNIA, ASSIGNOR TO BARKER BROS., INCORPORATED, F LOS AN GELES, CALIFORNIA, A CORPORATION 01 DELAWARE TABLE DESK Application filed October 21, 1929. Serial No. 401,052.

This invention pertains more specifically to a school desk whose supporting legs may be adjusted vertically in order that the desk top may be raised or lowered to conform to persons of different heights when using the same.

A main object is to provide a simple supporting leg construction in which the legs may be quickly and accurately increased or diminished in length to vary the distance of the desk top from the floor.

In school desks the supporting legs are of uniform length, such lengths being determined by the average sizes of the pupils. While such desks have in the main proven generally satisfactory, yet in the case of unusually short or tall pupils when seated at the same have proven somewhat unsatisfactory. By means of the device herein disclosed the various desk supporting legs may be quickly and accurately adjusted as to length to bring the desk top to the required height from the floor to suit the pupil occupying the same.

Other objects and advantages will be apparent from the following specification, reference beinghad to the accompanying drawings forming a part thereof, in which:

Fig. 1 is a rear elevation of the desk;

supporting legs in section to disclose the adpreferably consist of metallic tubular mem-- bers 10 forming the upper stationary sections, and solid wooden lower members 11 Fig. 2 is an end elevation with one of the that are telescopically mounted in the upper members or sections 10. One face 12 of each member 11 is provided with a vertical groove 13 and in these grooves are formed a plurality of cylindrical recesses or bores 14 equally spaced apart along the grooves.

Secured by rivets to one of the outer faces 15 of each of the upper metallic members is a fiat spring arm 16 whose free end 17 is turned outwardly from the face 15 of the member in order that it may be grasped by the fingers when it is desired to adjust the lower leg member. Secured to the inner faces of the spring arms and at a short distance above the curved ends 17 are cylindrical looking lugs 18 that extend through openings 19 in the faces 15 of the metallic members, said lugs engaging the recesses or bores 14 to hold the lower leg members in adjusted relation to the metallic members.

By forming the-bores 14 in the vertical groves 13' hereinbefore referred to, it will only be necessary to slightly move the spring arms outwardly in order to disengage the lugs from the bores when making a leg adjustment.

As the recesses or bores 14 in the lower leg members are all spaced alike it will be clear that when the legs are adjusted all will be of equal length.

The desk above described may be utilized not only by school pupils, but by extending its legs to their maximum length it may be conveniently used by persons, such as draftsmen, in an unseated position.

I claim:

A desk or table construction comprising a table top provided adjacent its edge with depending aprons, a plurality of hollow rectangular sheet metal leg members rigidy secured to the underface of the top, each of said members having a reinforcement therein at their upper ends, said reinforcements being secured to the table top, a plurality of solid wooden leg members mounted to slide within the hollow leg members, each of said solid members being provided on one oftheir faces with a vertically disposed groove, said groove having a plurality of spaced bores or recesses formed therein, spring locking members secured at one end to the outer faces of the hollow leg members, a lug formed on the free end of each of said locking members and extending through an opening in the hollow members and engaging the bores in the grooves to maintain the solid 1e members in adjusted relation to the hollow eg members.

In testimony whereof I aflix my signature.

DANIEL G. ANDERSON.
