SCHOOL DESK.

APPLICATION FILED MAR. a, 1909.

GEORGE H. PARKER, 0F ATLANTIC CITY, NEW JERSEY.

SOHO OL-DESK.

Specification of Letters Patent.

Application filed March 3, 1909. Serial No. 481,116.

To all whom it may concern:

Be it known that I, Gnonon H. PARKER, a citizen of the United States, residing at Atlantic City, in the county of Atlantic and State of New Jersey, have invented certain new and useful Improvements in School- Desks, of which the following is a specification.

My invention relates to improvements in school desks, the object of the invention being to provide an improved construction of desk mounting, which permits the desk to be adjusted vertically in accordance with the size of the child occupying the same.

A further object is to provide improvements of this character, which will be so constructed that there will be practically no lateral wabbling or movement of the desk, and yet it may be adjusted vertically at will.

lVith these and other objects in view, the invention consists in certain novel features of construction, and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1, is a view partly in vertical section illustrating my improvements. Fig. 2, is a view in section on the line 22 of Fig. 1. Fig. 3, is a view in section on the line 33 of Fig. 1, and Fig. 4, is a view in section on the line 4-4 of Fig. 1.

1 represents a base adapted to be secured to the floor in any approved manner, and having an upwardly projecting rectangular column 2 inclosing a hollow post 3, which latter projects upwardly beyond the upper end of column 2, and is provided with longitudinal flanges or tongues a, to enter grooves 5 in the inner sides of a rectangular sleeve 6. The sleeve is constructed to nicely fit around post 3 and between the same and the column 2, and will permit vertical adjustment of the sleeve, there is practically no lateral movement owing to the close connection. The upper end of sleeve 6 supports and is secured to an ordinary school desk 7 braced by a web bracket 8 connecting the desk with the sleeve as clearly shown in Fig. 1.

9 represents a screw threaded rod, which is positioned within the hollow post 8, and its threads engage screw threads in the upper portion 10 of said post. The extreme upper portion of the rod is smooth, and made angular as shown at 11 for the reception of a key 12 to turn the same, and a ring or collar 13 is secured to the rod by means of a screw 14, and is located between fixed rings 15 in sleeve 6, so that when said rod is turned in one direction, it will move the desk upward, and when moved in the opposite direction will draw the desk downward to adjust the latter to the proper height.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not restrict myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a device of the character described, the combination with a base, a rectangular hollow column projecting upwardly on said base, a rectangular post projecting upwardly on the base and located concentrically within the column, tongues or flanges on opposite sides of said post, a rectangular sleeve mounted between said post and column and having longitudinal grooves receiving said tongues or flanges, a screw threaded rod having screw threaded engagement with said post, a head secured to said rod and fixed rings within said sleeve at opposite sides of said head, whereby when said rod is turned the sleeve will be moved vertically relative to the post.

2. In a device of the character described, the combination with a base, of a vertical column projecting upwardly on the base, a post projecting upwardly on the base and located concentrically within the column, tongues or flanges on opposite sides of said post, a sleeve mounted between said post and column and having longitudinal grooves receiving said tongues or flanges, said post having a screw threaded socket, a screw Patented Mar. 8, 1910.

threaded rod engaging the threads in said name to this specification in the presence %ock1et, a eolllai' fixed on said rod, andfrings of two subscribing Witnesses.

Xec in saic s eeve at opposite sides 0 said collar, whereby when said rod is turned the GEORGE PARKER 5 sleeve will be moved longitudinally relative Witnesses: i to the post and column. CHAS. WV. OAT,

In testimony whereof I have signed my 1 GEORGE A. PARKER.
