F g i A housing 8 depends from the central part of From the foregoingit will be seen that I the channel bar 7 and a pair or" levers 9 is, have provided means'whereby-i a tray can be pivoted to the bar 7 at the sides thereof and easily and quickly attached to its supporting Q" t member, with means for adjusting the height of the supporting member from the floor so that the tray can be held at the most desirable height. The upper tray holding means can also be adjusted toward and away from the lower means and the upper means can be entirely removed when is only necessary to use the device with one tray.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

An example of this kind is shown in Figure 6, wherein a slightly modified form of control for the latch bars is illustrated. In this construction, springs 13 tend to normally hold the levers 9 in the position illu e trated in the view under consideration. The springs are attached to the levers and to bar 7, and the latch bars 10 therefore move to engaging position under the action of springs 13 and 13.

What I claim is 1. A device of the class described comprising a pair of uprights, sleeves slidably arranged on the uprights, manually operated latch means for holding the sleeves in adjusted position on the uprights, a cross piece connected with the sleeves, tray clamps carried by the cross piece, additional tray clamps, and means for securing the additional clamps to the sleeves and permitting vertical adjustment with'reference to said sleeves. A

2. A device of the class described comprising a pair of uprights, sleeve-s slidably arranged on the uprights, manually operated latch means for holding the sleeves in adjusted position on the uprights, a cross piece connected with the sleeves, tray clamps carried by the cross piece, a second cross piece,

depending members connected with the ends thereof, means for adj ustably connecting the end members with the sleeves and tray clamps carried by the second cross piece.

3. A device of the class described comprising a pair of uprights, sleeves slidably arranged on the uprights, manually operated latch means for holding the sleeves in adj usted position on the uprights, a cross piece connected with the sleeves, tray clamps carried by'the cross piece, a second cross piece, depending members connected with the ends thereof, means for adjustably connecting the end members with the sleeves, tray clamps .carried by the second cross piece and means for adjusting the clamps on each cross piece toward and away from each other 4:. A device of the class described comprising apair of uprights, sleeves slidably ar- .ranged on the uprights, a cross piece having its ends connected with the sleeves, levers having their upper ends pivoted to the cross piece at the center thereof, a latch bar con nected with each lever, the sleeves having openings therein for receiving the outer ends of the latch bars and the uprights having openings therein for receiving the outer ends of the cross bars, springs for normally holding the latch bars in projected position, said latch bars being moved to releasing position v by moving the levers toward each other and tray clamping means carried by the cross piece.

5. A device of the class described comprising a pair of uprights, sleeves slidably arranged on the uprights, a cross piece having its endsconnected with the sleeves, levers having their upper ends pivoted to the cross piece at the center thereof, a latch bar connected with each lever, the sleeves having openin s therein for receiving the outer ends of the latch bars and the uprights having og'zenings therein for receiving the outer ends of the cross bars, springs for normally holding the latch bars in projected position, said latch bars being moved to releasing position by moving the levers toward each other, tray ciainping means carried by the cross piece and means for communicating the movement of one latch bar to the other bar.

In testimony whereof I afiix my signature.

ROBERT C. BURNLEY.
