Abstract
Abstract An artist's easel comprises a framework adapted to receive and hold a canvas, and one or more wheels mounted on the framework and enabling the easel to be wheeled to and from a place of use. The easel also includes means for maintaining the frame in its normally intended attitude of use, and means which, in use, engage the ground on which the easel stands to resist any tendency of the easel to move along the ground.

Claim 1
Independent Claim
228 words
An artist's easel comprising a framework comprising a horizontally oriented base member and upper and lower telescopically-connected, vertically-extending members, the lower member being fixed centrally of said base member a pair of wheels mounted on opposite ends of said base member enabling said easel framework to be wheeled to and from a place of use; an upper clamping member fixed on said upper vertically-extending member, adjusable by movement of said upper vertically-extending member, and including means for securing a canvas to said framework, a lower clamping member adjustably supported for vertical movement on said lower vertically-extending member and means for securing the same in a selected fixed position relative to said upper clamping member, said lower clamping means further including means to secure a canvas on said framework during movement, means comprising an A-frame having its apex pivotally mounted on the lower end of said lower vertically-extending member and means to secure the same either in a position with the legs of the A-frame substantially coplanar with said vertically extending members permitting movement of said easel on said wheels, or in a downwardly and outwardly extending position to engage the ground and secure the easel against movement along the ground, and said A-frame defines a planar support for a canvas when the easel is being wheeled when said A-frame is secured in said position against said vertically-extending members.

Claim 7
Dependent Claim
57 words
An easel according to claim 5 in which said A-frame includes a cross support member positioned to engage the rear of said parallel support members forming said upper and lower telescopically-connected, vertically-extending members to locate the front edge of the legs of said A-frame in a coplanar relation with the front edges of said parallel support members.
Claim 8
Dependent Claim
