6 is secured to the desk 7 at one side, and the desk 7 is positioned so that it overhangs this rod 6 at one end and the opposite end extends a considerable distance to approximately the other side of the chair seat when positioned on the cha-ir. It will be noted that the desk 7 is slightly pivotal upon the rod 6 so that the brace member 7L will not enga-ge the portion lb when it is desired to shift the desk relatively to the support 5, but when the member 7L rests against the portion 4l the frictional engagement will prevent its easy shifting.
Though we have shown and described a aarticular construction, combination and arrangement of parts and portions, we do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the purview of our invent-ion the construction, combination and arrangement substantially as set forth in the appended claims.
It is obvious that with this: construction there is provided an attachment to be used in connection with the conventional chair,
which may be readily secured to said chair,-
that provides an additional support on one side, that the device is adjustable so that i the desk may be raised and lowered relatively to the chair seat, that the desk may be shifted forwardly or backwardly relatively to the chair, that the desk may be tilted upon the .pivotal support so that it assumes varyingtilted positions as desired, that the attachment is made more rsecure by reason of the brace 2 which connects with said support some distance from the chair and to the cross bar on the front side of the chair, that the attachment is applicable for connection with various types of conventional chairs now in use and that the device itself is cheap and economical of construction, durable, easy to operate, easy to adjust and efficient in its action.
Having thus describedV our invention what we claim as new and desire to secure by Letters Patent, is-
l. A desk attachment for chairs, including a supporting member adapted to be secured to one corner of the conventi onal chair and extend. forwardly therefrom, uprights iixedly secured thereto with their upper ends extending above the supporting member` a non-tiltable vertically shiftable bracket member mounted between said uprights, means for holding said bracket iu various Vto frictionally engage the inner side of vertically shifted positions, a quadrant member pivotally mounted on said shiftable bracket and provided with upwardly extended between said uprights above .said sup-v porting member, thumb screw and nut means fo-r holding said bracket in varying shifted positions, a quadrant member mounted on said bracket provided with upwardly extending lugs, means for securing said quadrant member in various shifted positions, a desk supporting rod shiftably and revolubly mounted in said lugs, a desk member provided with downwardly extending lugs secured to the ends of said rod and a bracket member secured to the under side of said desk member adapted to butt againstV and frictionally engage the inner sidek of said shiftably mounted bracket.
3. A desk attachment for chairs, including a supporting member adapted to be secured to one corner of the conventional straight chair and extend forwardly therefrom, channel uprights fixedly secured thereto with their upper ends extending` above the supporting member, a non-tiltable and vertically shiftable bracket member mounted between said uprights above said supporting member, a quadrant member provided with upwardly extending lugs andA pivotally mounted on said bracket, a desk .member shiftably and pivotally mounted in the lugs of said quadrant member and provided with a single.downwardly extending bracket portion on its underside, positioned Y said shiftably mounted bracket.
ln testimony whereof, we have hereunto set our hands at San- Diego, California this 6th day of June 1921.
