Abstract
18,512. Ashton, L. D., Hamer, J. J., and Alderson, J. S. Sept. 3. Drawing-boards.-Paper, fabric, &c. is attached to drawing and other boards or frames by means of slotted wedges or inclined surfaces. The wedge b, Fig. 4, is disposed between the board a and washers or a plate f held by screws d passing through the slots c in the wedge. To prevent dragging of the paper, a lath g having recesses at h may be interposed between it and the wedge b. To obtain a flat surface at the edges of the board to permit the use of a T-square &c., the wedges may be formed as shown in Fig. 8, the bearing- surfaces for the screw heads d being protected by a plate k if necessary. Grooves or-corrugations may be formed in the opposing surfaces of the wedges, laths, or board. According to the Provisional Specification the wedge or wedges may be operated by a cam or the like.
