Dec. 14, 1948. c E. THOMAS MEANS FOR SECURING A CANVAS TO A FRAME Filed July 24, 1945 INVENTOR. CARROLL E. THOMAS: BY & I; f
ATTORNEY.
Patented Dec. 14, 1948 UNITED STATES PATENT MEAN-S' non. SECURING rAcGANVAS -:'r;o 2a
FRAME. I
This invention relates :to improvements in artists equipment, and .moreparticularly to novel means for mounting a. canvas, fabric. or paper sheet, on a rectangular frame,
An object of my invention-is to provide novel means for securely mounting a canvas on a supporting frame.
Another object ofmy invention isto provide novel meansfor quickly securing a canvasto a rectangular supporting frame the said. means embodying a construction whereby the canvas may be securely held in a taut position without the use of tacks or other. independent means.
A further object of my invention is to provide artists equipment of the kind characterized, embody novel means-by which a .canvas may be readily mounted on a supporting frame andsecurelyv held thereon while its outer surface is painted by an artist, andwhich permits the subsequent tacking of the canvas-to the frame for permanent mounting.
Other and further objects of my invention will be pointed out hereinafter, or will be indicated in. the. appended claims, or will be obvious to one skilled in the art uponan' understanding ofthe present disclosure. For the purpose of this application I have elected to show'herein certain forms-and details of meansfor-mounting an art-- ists canvas on a rectangular frame representative ofmy invention. It is-to be understood, however, that the embodiment of my invention herein shown and described is. for the purpose of illustration only and that therefore it isnot to be regarded as exhaustiveof the variations of the inventiom nor is it to be given an interpretation such as might have the effectof limiting the claims, short of the true andmostcomprehensive scope of the invention in the'art.
In the accompanying drawings:
Fig. 1 is a top plan view showing an artists canvas mounted on a rectangular frame by means of the present invention;
Fig. 2 is a bottom plan view of the same;
Fig. 3 is an enlarged longitudinal sectional view of the same;
Fig. 4 is a perspective view of a fragmentary part of one of the clamping members; and I Fig. 5 is a perspective view of another fragmentary part of the clamping member.
Referring to the drawings, the numeral I designates the side members of an open rectangular frame which is commonly used to support an artists canvas, fabric or paper sheet, 2. Heretofore, it has been the common practice for artists to secure the turned back edges of a canvas 2 to a frame bymeans of closely. spaced tacks which were driven throughthe. canvas and into the edges of the frame. at-each of the four sides of the latter. Itordinarily takes considerable time and effortto properly attach a canvas .toaframe by the common method now used, and it likewise requires considerable time to removethetacks when the canvas is. detached from the frame. By means of the present-invention a canvas may be quickly secured. toand detached fromasupporting frame.
The frame members I are suitablyinterlocked at their engaging end-s, and-corner wedges-tare commonly used to spread the said members and thereby enlarge the frame to suitably maintain the canvas in a taut position.
The present inventioncomprises two pair of angle irons or members iand 5 which preferably are slightly shorter than the length of'the side members I of the frame with which they normally engage. Each of the angle members 4 and. 5 are formed.with longitudinally disposed sides. 6 and (which are arranged at substantiallyright angles with respect to oneano-ther. Thesides 6 of the angle members normally engage with the edge portions of the canvas extending over. the side edges of the frame, and the sides I normally engage with the frames rear side. The longitudinal edges of the sides I of each of the angle members-land 5 are bent inwardly and outwardly to provide a-reinforcin-g strip 1, the: said strip constituting a fastening member lawhere. the side Iis cut-away midway between its ends, as at 1b, for anchoring an end of the clamping member 8.
Thesides 6 of each of the angle members are formed atspaced intervalsalong their lengths with pointed punched out tongues fi', or other sharp projecting members, which are adapted to extend through the canvas and penetrate the side edges of the frame when the angle members are applied to the latter. The sides 6 of each of the angle members are suitably cut away at spaced intervals along their outer edges to provide openings (id for the applying of tacks or other securing means for the permanent attachment of the canvas to the frame, if so desired.
Each of the opposed pair of angle members 4 and 5 are urged toward each other by spring actuated clamping members 8 which may assume any one of a number of different forms. In the particular embodiment shown in the drawings, the clamping members each comprise elongated flat bars 9 having their inner ends connected to a helical spring l0 and their outer ends formed with suitable means for detachably engaging with. a fastening member Ia of the angle members. The elongated bars 9 have substantially the same thickness as the sides I, thereby permitting them to lie in the same plane as the said sides when attached to the latter. The helical springs ID, in cross section, preferably have a somewhat rectangular shape, rather than being circular.
When the angle members 4 and 5 are brought into firm engagement with the turned back edge portions of the canvas, the pointed tongues 6 of the sides s project through the said canvas and penetrate the side edges of the frame, thereby preventing the slipping of the edge portions of the canvas with respect to the said side edges of the frame. The spring actuated clamping members 8 each exert an inward pressure on their respective pair of angle members 4 and 5, thereby causing the sides 1 of the latter to firmly engage with the turned back edge portions of the canvas and remain in such positions until they are subsequently detached.
In the event the canvas is to be permanently secured to the frame prior to the detachment of the angle members, suitable tacks may be driven through the turned back edge portions of the canvas and into the frame at points where the openings 6a in the sides 6 occur.
It is apparent that the present invention may be adapted for use with respect to frames of different shapes by changing the general shapes of the angle members 4 and 5 so they conform to and fit upon the sides of the frame with which they are used.
What I claim is:
1. In means for securing a sheetto a frame, pairs of opposed elongated angle members substantially L-shaped in cross section arranged for engagement with the sheet where it is extended over the side edges of the frame and also with the rear side of the frame, the said angle members being independently adjustable, and spring clamp means connected to and positioned between the elongated members of each pair, whereby the said members of each pair are urged toward one another to firmly engage with the sheet and clamp it against the edges of the frame.
2. In means for securing a canvas to a frame, pairs of opposed elongated unconnected and independently adjustable angle members arranged for engagement with the canvas where it is extended over the side edges of the frame, pointed means carried by the angle members for penetrating the canvas and the side edges of the frame whereby the canvas is normally prevented from slipping with respect to the side edges of the frame, and spring clamp means connected to and positioned between the elongated members of each pair, whereby the said members of each pair are urged toward each other to main tain the said members in positions so the pointed means carried thereby remain in penetrating engagement with the canvas and the frame.
3. In means for securing a sheet to a frame, pairs of opposed elongated angle members arranged forv engagement with the sheet where it is extended over the side edges of the frame, pointed means carried by the angle members for penetrating the sheet and the side edges of the frame, whereby the sheet is normally prevented from slipping with respect to the side edges of the frame, and spring clamp means connected to and positioned between the elongated members of each pair, whereby the said members of each pair are urged toward each other to maintain the said members in positions so the pointed means carried thereby remain in penetrating engagement with the sheet and the frame, the said angle members having spaced openings arranged therein for the insertion of tacks for the permanent securing of the sheet to the frame when the angle members are removed.
4. In means for securing a sheet to a frame, pairs of opposed elongated members arranged for engagement with the sheet where it is extended over the side edges of the frame, the said elongated members having spaced openings arranged along their lengths for permitting the driving of independent pointed members through the sheet and into the frame for the permanent attachment of the sheet to the frame, and spring clamp means connected to and positioned between the elongated members of each pair, whereby the said members of each pair are urged toward one another to firmly engage with the sheet and clamp it against the edges of the frame.
