FOLDING EASEL Filed Jan. 25, 1961 2 Sheets-Sheet 2 DUNCAN C. KILLEN ATTORNEYS United States Patent Ofi 3,095,665 Patented July 2, 1963 ice 3,095,665 FOLDING EASEL Duncan C. Killen, 2521 Durant Ave., Berkeley, Calif. Filed Jan. 23, 1961, Ser. No. 84,309 7 Claims. (Cl. 45-129) This invention relates to improvements in a folding easel and more particularly to foldable easels of the type used by artists to support canvas-covered stretcher frames and the like, which provide the working surface upon which the artist draws or paints.

Previous easels generally support the stretcher frame on a narrow ledge or shelf and the partially completed picture is subject to being dislodged and damaged. Devices heretofore provided for clamping the stretcher frame to the easel, have been inadequate for the purpose, or have unduly interfered with the application of the paint or other medium to the canvas. Moreover, the earlier easels are shaky, particularly when used on uneven surfaces, and this can often create technical difliculties for the artist.

The present invention contemplates an artists easel in which the foregoing disadvantages are overcome and which provides an ideal support for all types of objects upon which pictures are drawn. The stretcher frame or other object is held securely in place in a manner permitting the artist to freely extend his brush strokes beyond the edges of the canvas so as not to interfere with his painting technique.

Accordingly it is a principal object of the present invention to provide a folding easel which will securely clamp and solidly support canvas-covered stretcher frames and the like in any position desired 'by the artist.

Another object of the present invention is to provide an easel of the character described in which the clamping means extends laterally over a considerable distance so as to insure that pressure against the working surface of the picture will not swing the picture or dislodge it from the clamping means.

A further object of the invention is to provide an easel of the character described in which the painting surface is completely free and the clamping means does not interfere with the edges thereof so as to permit the artist to paint freely over such edges.

Yet another object of the invention is to provide an artists easel which will sit solidly on uneven surfaces such as warped floor-s or on the ground.

A still further object of the invention is to provide an artists easel of the character described in which the picture may be oriented or tilted to any desired position with respect to the horizon.

Another object of the invention is the provision of a port-able easel of the character described which is solid, sturdy and trouble-free in operation, the structure being designed to fold compactly when not in use and being adapted for rapid mass production from inexpensive materials. 7

Further objects and advantages of my invention will be apparent as the specification progresses, and the new and useful features of my folding easel will be fully defined in the claims attached hereto.

, .by bolt means 28.

The preferred form of my invention is illustrated in i While I have shown only the preferred form of my invention, it should be understood that various changes or modifications may be made Within the scope of the claims attached hereto without departing from the spirit of the invention.

Referring to the drawings in detail, it will be seen that my folding easel consists basically of a generally upright standard 11 having a flat front face 12 formed with a vertically extending slot 13, a pair of

elongated clamping devices

14 and 16 extending laterally across front face 12, and locking means 17 and 18 on

devices

14 and 16, respectively, the

means

17 and 18 being engageable with slot 13 and formed for adjustably securing the clamping devices to the standard 11 in clamping engagement against the top and bottom edges 19' and 21, respectively, of a canvas-covered stretcher frame 22.

As here shown, the

clamping devices

14 and 16 are similar in construction and, as may best be seen in FIGURE 3, each includes an elongated bar 23 mounted on the standard 11 and extending laterally across the flat front face 12.

'The bars 23 are of triangular cross-section with the base of the triangle providing a flat face 24 in sliding contact with the front face 12 of the standard.

Carried on the bars 23 are elongated clamping members 26 of L-shaped cross-section. The confronting edges 27 of the members 26 are adapted for clamping engagement against the top and

bottom sides

19 and 21 of the stretcher frame 22 upon movement of the clamping members 26 toward each other.

The clamping members 26 are urged toward each other Included in each of the means 28 is a bolt member 29 extending perpendicularly from the outer faces 31 of the bars 23 through the clamping members 26. Thumbscrews 32 are threaded on bolt members 29 so that tightening down of the thumbscrews will tend to displace the clamping members 26 toward each other.

Locking means is also provided for adjustably securing the

clamping devices

14 and 16 at the proper vertical spacing to accommodate the frame 22 intended to be clamped to the easel. This means includes bolt members 33 secured to and extending perpendicularly from the flat faces 24 of the bars 23 through the slot 13 in the standard 11. Thumbscrews 34 are threaded on the bolt members 33 and may be tightened down to clamp the bins 23 to the standard at the desired positions there- .a ong.

The easel of the present invent-ion may be constructed of any suitable material but, in order to reduce fabrication and material costs, I prefer to utilize wood secured together by metal fasteners and brackets. Thus, and as here shown, thestandard 11 may conveniently comprise a wooden plank and the bars 23 and the clamping members 26 supported thereby may also be formed of wood. With this construction I have found it convenient to combine the '

bolt members

29 and 33 into a single unit passing through the bar 23 in the manner illustrated in FIG- URE 3 of the drawings. a

As an important feature of the present invention, the

clamping devices

14 and 16 are adapted to engage the stretcher frame 22 in such manner as to avoid interference with the brush strokes of the artist. For this purpose the confronting edges 27 of the clamping members 26 are of V-shape and are proportioned and positioned to engage the stretcher frame 22 in spaced relation to the front surface 36 of the canvas. This permits the artist to extend his brush strokes past the edges of the canvas and hence does not interfere with his brush technique. Of course, painting past the upper and

lower edges

19 and 21 of the stretcher frame may deposit paint on the clamp: ing members 26, but this paint presents no problems and can easily be removed.

In accordance with the present invention the

clamping devices

14 and 16 are normally secured perpendicular to the standard 11, but if desired the clamping devices may be tilted so as to allow the artist to orient his picture at any .desired angle to the horizontal. This adjustment made possible by the length of the clamping devices together with the structure of the locking means which cooperates with the broad front surface of the standard 11 to securely hold the clamping devices at any desired angle of inclination.

For convenience a shelf 37 may be secured at any desired height to the standard 11 by a locking device consisting of a bolt 38 sl-idably engaged through the slot 13 and having a thumbscrew 39 threaded thereon. The shelf 37 is preferably provided with fingers 41 adapted to support paint brushes or the like, and may also incorporate turpentine and paint containers 42 having clips 43 engageable with the shelf 37.

The standard 11 is preferably supported in the desired position by brace member 44 attached by means of a hinge 46 to the rear surface of the standard medially of its length. An arm 47 is pivoted at 48 to the standard and is formed with a slot 49 through which is engaged a bolt 51 having a thumbscrew 52 for locking the brace at a desired angle relative to the standard 11.

As a feature of my invention the easel will sit solidly on uneven surfaces and may be adjusted relative thereto to position the slot 13 in a vertical plane. This is accomplished by

elongated foot members

53 and 54 for the standard 11 and brace 44, respectively, the foot members normally being perpendicular to the standard and brace but incorporating provisions for effecting independent tilting adjustment so that each foot member will be in firm contact with the surface upon which the easel is resting.

The desired tilting action of the foot members is obtained by pivoting them on bolts 56 projecting from the standard 11 and brace 44, respectively. Thumbscrews 57 are provided on the bolts for securing the

members

53 and 54 in the desired positions. Bracket means 58 is also provided for rigidly securing the

members

53 and 54 at the desired angles. As here shown, the bracket means 58 are formed of sheet metal bent to an L-shaped crosssection and are secured by pins 59 to the

members

53 and 54. The distal ends of the brackets are formed with elongated slots 61 through which bolts 62 project. Thumbscrews 63 may be backed off to permit relative adjustment of the brackets and may then be tightened down to hold the foot members rigidly in place.

From the foregoing it will be seen that I have provided a novel folding, portable artists easel adapted for firmly and solidly supporting a canvas-covered stretcher frame or the like in any desired position and without interference with the painting being done on the surface of the canvas.
