DAVID N. BUTTERFIELD, OF NElV BOSTON, NEW HAMPSHIRE, ASSIGNOR OF ONE-HALF TO HENRY F. TVILLARD, OF CAMBRIDGE, MASSACHUSETTS.

DESK.

SPECIFICATION forming part of Letters Patent No. 310,877, dated January 20, 1835.

Application filed May 5, 1884.

Children, of which the following is a specilication.

The object of my invention is to so construct the supports for a desk that they may be readily removed or replaced, also that when the supports are separated from the desk all of the parts forming the supports can be separated and packed in a small space. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a perspective view of my desk complete; Fig. 2, a perspective view showing the supports separated from the body of the desk and packed thereon.

In the drawings, A represents the body of the desk. B B B B are the supports of the desk. These supports are framed together near their center so as to form an X, as shown. The upper ends have attached to them a metal plate, 0. This plate 0 adds greatly to the strength of the supports, and serves as a device i'or attaching the supports to the body of the desks. The attaching device consists of (No model.)

the plate O, having a nick, D D, at each end, 0 so that it (the plate) can slide in under the heads of the screws D D, and thus be held in position. The cross-bar H terminates at each end in a pintle and screw, the pintle passing entirely through the legs at the joint, and is 5 secured by a nut, K, Fig. 1. This construction of the supporting parts admits of their being removed from the body of the desk without the use of tools, it only being necessary to unscrew the nuts K by the hand; then o by. springing the supports a little way in the direction of the length of the desk the bar H can be removed; then by sliding the supports inwardly toward the center of the desk the plate 0 will slide out from the screws D D and 5 the supports will be entirely separated from the body of the desk.

I claim as my invention- In a childs desk, the combination of the crossbar H, the supports B B, and the plate 50 G, nicked as shown, with the screws D D and the body A of the desk, all constructed sub stantially as described, and for the purpose set forth.

DAVID N. BUTTERFIELD.
