' COMBINED DESK AND SEAT FRAME.

Specification of Letters Patent.

Patented Oct. 12, 1920.

Application filed May 15, 1919. Serial No. 297,321.

To all whom it may concern:

Be it known that I, THOMAS E. MoNUL'rY, a citizen of the United States, residing at San Francisco, in the county of San Francisco and the State of California, have invented certain new and useful Improvements in Combined Desk and Seat Frames, of which the following is a specification.

This invention relates to desk and seat frames for school purposes, and combines in part certain features more fully shown and described in my Patents, 1,291,975 and 1,291,976, to which reference is had. I

The present invention relates more especially to a tubular frame which supports an adjustable desk and a seat, also adjustable, for use of the pupil using said desk. In the forms shown in my previous patents above referred to the seat was carried by the back of a desk, or as used in a school room, in ad vance of the desk.to which it was attached. Such desks are usually arranged in parallel rows extending from the front to the rear of the room. Where the desk is attached to the back of a seat, thus putting the seat in advance of the desk, it is obvious that no seat would be provided for the rearmost desk of each row. The present invention especially provides for this. Furthermore it provides for increasing or decreasing the distance between the desk and the seat, and

also makes the seat supporting tubular mem bers detachable from the desk supporting members.

The invention consists in the novel features of construction and combination hereinafter described, pointed out in the claim, and shown in the accompanying drawings in which;

Figure 1 is a side elevation of the frame with desk and seat attached.

Fig. 2 is a rear elevation of the same.

In the drawings 1 designates a tubular A-shaped frame braced by a welded cross piece 2. It supports on its rear member a slidable bracket 3 supporting a desk 4.

It willbe readily understood that two of these frames are employed, connected by a cross member 5 at top and a similar member 5 between the braces.

At the front lower corner the frame is bowed or curved as at 6 to form a supporting foot, thereby lifting the horizontal base member 7 above the floor level. The base member 7 is integral with the frame and extends rearwardly. This member is also duplicated on the opposite side of the desk.

At their rear ends these members are provided with coupling 8; and pipe sections 9 connect, by curved unions 10, the uprights 11, also of tubular form, with the base members 7. The unions or coupling 10 by reason of their increased diameters with respect to the members 7, also rest on the floor and form rear foot portions as well as connecting members. By regulating the length of the sections 9, or the extent to which they are screwed into the unions 9 and 10 distance of the uprights 11 from the desk 1 can be regulated.

The uprights 11 are braced and connected by welded cross pieces 12. A seat 13 having beneath it a drawer 14 is slidably mounted on the uprights 11. A bar 15 is connected to the back of the seat, having at its ends sleeves 16 which slide on the uprights 11. A similar bar with sleeves 16 is connected tothe lower, drawer portion of the seat. An adjusting screw 18 is mounted between the braces 12 and works through the cross bar 15, the ends of said screw being mounted to rotate loosely in blocks 18 carried by the braces 12. The screw has a squared portion 19 and by turning the same with a wrench the seat 13 is adjusted to the proper height.

The advantages of a desk frame so constructed will be obvious to those manufacturing and using school desks.

It forms the desk and seat frame in a common, light unit, easily cleaned and kept free from dust and therefore advisable from a sanitary standpoint, the floor contact is reduced to a minimum, so there is little space for the collection of dirt and dust. It is not necessary to screw to the floor to make it steady and it can be readily removed from one room to another, and disconnected and easily packed for shipment.

What I claim is A combined desk and seat frame comprising two tubular A-shaped members, means connecting said members in spaced parallel relation with each other, each frame having an integral horizontal base for the A-frame, c'urved downwardly at the front to form a supporting foot portion, and extending rearwardly from the frame adjacent to, but out of contact with the floor; upright seat supporting members detachably secured to the rear ends of said base members and connecting means forming rear foot portions.

In testimony whereof I have afiixed my signature.

THOMAS E. MoNULTY.
