Description

Aug, 9, 1932- L. c. CLARK COMBINED CANVAS STRETCHER AND PICTURE FRAME Filed Sept. 5, 1930 Patented Aug. 9, 1932 ED STATES LUCIEN C. CLARK, F BRIGHTON, MASSACHUSETTS' COMBINED CANVAS STRETGHER; Ann PICTURE FRAME Application filed September My invention relates to improvements in canvas stretching frames and has for its object to provide a frame for stretching canvas paintings which may also be used as a pic- 'gture frame for the painting when placed on exhibition.

A further object of the invention is to provide a stretching frame composed of separable strips which are adjustable, interchange- 1o able and reversible and in addition are adaptable for framing a painting.

Another object of the invention is to provide a device of the above-mentioned character which is simple and durable in construction, reliable and efficient in use and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing, forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. l is a fragmentary plan view of the frame,

Fig. 2 is a cross section taken on, lines 22 of Fig. 1,

Fi 3 is a perspective view of the mitre joint for connecting the strips, and,

Fig. 4: is a similar view looking at the joint from another angle.

In the drawing, wherein for the purpose of illustration 1 have shown a preferred embodiment of my invention, the frame 5 consists of a plurality of strips 6, the ends of which are mitred as at 7, and each mitred end has a tongue 8 and groove9 for interlocking engagement with the mitred ends of adjoining secticns. Both faces of the strips have beads 10 along their marginal outer edges, over which the canvas extends when stretched and the inner edges of the strips on both faces of the strips are rabbeted forming recesses 11 which surround the inner edge of the frame when the strips are joined together. lVhen the strips are used for framing a painting, they are placed around the frame on which the canvas is stretched, the edges of the stretcher frame being seated in the recesses 11 and secured in'place by suit- 3.1930. Serial No. 479,525.

able fasteners. If it is desired to adjust the frame when stretching the canvas, small metal wedges, not shown, may be drivenbetween the joints '12 at the corners of the frame. ing large canvases, it is necessary to brace the frame by a center bar 13, which with my frame may be applied to the frame without When the frame is used for stretchhaving to remove the canvas, since the ends of the bar fit in the recesses 11, being held in place by the T-shaped plates let attached to the strips 6 and center bar 13 by screws 15.

Thus, it is seen that I have provided a canvas stretcher frame which in addition to having all the advantages of the conventional type of frame, may be used as a picture frame, by reason of the rabbeting around the inner edges of the frame and also has the advantage of being able to add brace bars to the frame whenever desired without having to remove the canvas.

It is to be understood that the form of my invention herewith shown and described is to betaken as a preferred example of the Same and that certain changes in the shape, size and arrangement of the'parts may be made without having to depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim 1. A combined canvas stretcher and picture frame comprising a plurality of double-faced strips, each face having a heading at its outer edge, the inner edges of the'strips being rabbeted to form recesses within which to fit smaller frames, said strips having their ends mitred and also formed with interfitting tongues and recesses, and said rabbeted edges of the strips extending throughout the tongues of the joints.

2. A combined canvas stretcher and picture frame comprising a plurality of doublefaced strips,each face having a beading at its outer edge, the inner edges of the strips being rabbeted to form recesses on both faces for selectively mounting a smaller frame and also formed with interfitting tongues and recesses, and said rabbeted edges of the strips extending throughout said tongues. Q

3. A combined canvas stretcher and pic ture frame comprising a plurality of double- 5 faced strips, each face having a beading at its outer edge, the inner edges of the strips being rabbeted to form recesses on both faces, said strips having their endsmitred and also formed with interfitting tongues and grooves,

said rabbeted edges extending throughout said tongues, a brace bar extending across the frame with the ends of the bar resting within the recess one face ofthefrarine, I and metal plates securing the bar in position 1 5 to the frame, the recess on theroppositeface" i of the, frame forming a seat for receivinga sr'r'iai'lerfraine.
