Abstract
Abstract An artist''s collapsible easel has been provided which can be mounted either on a table or upon a wall and wherein the frames of the same can be angled and rigidly held in the angled positions against collapse upon one another by slide plates having lateral projectons that can adjustably engage between the side edges of the frames close to the point of the pivot bolt connection between the frames and thereby eliminate the need for the usual links or easel brackets at remote positions from their pivot connections with one another and thereby provide for an artist''s easel of the collapsible type which is more compact and without so many parts. U-shaped base and canvas supporting frames are formed of regular tubular or bar stock and brackets for engagment with the upper and lower edges of the artist''s canvas frame are connected in an adjustable manner upon the legs of the canvas supporting frame, while the free ends of the frame legs are joined together by the pivot bolt connections and held against collapse by the lateral projections of slide plates held in common with leg ends and the same pivot bolts.

Claim 1
Independent Claim
201 words
An artist''s collapsible table and mountable easel for supporting canvassed frames comprising a U-shaped framed canvas supporting frame having a bight portion and two leg portions extending therefrom and a U-shaped base frame having a bight portion and two-leg portions extending therefrom and pivotally connectd to the framed canvas supporting frame by their corresponding and respective leg portions pivot bolt means extending respectively through the ends of the respective joined leg portions of the two frames at their pivot connection with one another and slotted slide plates having laterally-struck extensions adjacent the pivot connection engageable with the inner edges of the frames adjacent to the pivot connection to prevent the collapsing of the frames one with the other and while in their adjusted positions and having elongated bolt receiving slots extending longitudinally thereof said pivot bolt means for pivotally securing the joined ends of the leg portions together serving in common for securing the slide plates to the leg portions of the frames in their adjusted positions and clamped together with the pivotal connection of leg portions and support brackets adjustably mounted on the framed canvas-supporting frame and adapted to engage the canvassed frames along their upper and lower edges thereof.
Claim 2
Dependent Claim
