ABSTRACT:
A studio easel for selective tension or compression clamping of a canvas painting stretcher frame having top and bottom cross bars in fixed upright position at a desired level has a pair of elongated channel tracks for mounting upright in laterally spaced relation on a studio wall with a pair of opposed shoes slidable in each track. Grip locks on the shoes secure them to their tracks, a stretcher frame support on one shoe of each pair engages a cross bar of the frame. A push-pull clamp on the other shoe of the pair engages the opposite cross bar of the stretcher frame. The shoes are mounted for stretch clamping the frame by positioning the frame support shoe above the push-pull clamp shoes, hanging the top cross bar of the frame on the support shoes, engaging the bottom support frame with the push-pull clamps and pulling the clamps to stretch the frame. In the compression loading position the support shoes are mounted under the push-pull clamp shoes with the bottom cross bar of the frame resting on the supports and with the clamps being pushed against the top cross bar to force the frame downwardly against the bottom supports. For small frames, a single track arrangement can be provided.
