To all whom t may concern.:
Be it known that I, VILLIAM BELL, of ButL falo, in the county of Erie and State of New York, have invented certain Iinprovenients in Drawing-Stands, described in the following speciiioation.
My invention relates to the combination oi' a hall having a part projecting Jfrom one side 0f the proper t'orni to receive the drawing-board or top, and a clamping device for iirinly holding the saine at any angle required; also, in arranging therewith a revolving rest and atchet, so constructed that the board niay revolve on a vertical axis, or raised or lowered,the object being to at'- ford an easy ineans of adjusting the board to any position that inay be desired.
Figure 1 is a front elevation of a stand einhodying iny invention. Fig. is a top view of the ball and clainp, showing the part to which the board or top is fastened. Fig. 5 is a section through the rest, showing the ratchet and the pinion for elevating or lowering the board.
A is the board or top. It is fastened to the piece L on the ball B. O represents the movable part oi" the clamping device. It is jointed at S by a pin passing through the standard D, 0il which the top fornis a part ol' the ball-clamp, as shown. G is a pinion, which enga-ges with a rack in the standard D for the purpose of adjusting l the saine vertically. It is more clearly shown in Fig. 3. F is a inovable collar, loosely fitted to the said standard, which drops by its own weight land engages with the pinion G for the purpose ot' preventing the descent oi' the saine, as clearly shown in Fig. 3. H is a sinall handwheel i'oiturning said pinion. E represents a tighteningscrew for operating the ball-clainp, and J is a screw i'oiI preventing the standard i'roin turning, or for holding it rigidly to the i'raine M when desired. The standard l), which passes down through the traine M, as plainly shown in the drawing, inay be either raised or lowered by litting up the collar F and turning the hand-wheel M y invention may be used to support a writing desk, cutting-board, table, artistls easel, or an engi'avers stand; and it is well adapted, and is intended, for any purpose where an adjustable table or board is required.
