DEVICE FOR MAKING DRAWINGS Filed April 5, 1961 NVENTOR fl GEORGE w. QUINN ATTORNEYS United States Patent I 3,063,162 DEVIQE FOR MAKING DRAWINGS George W. Quinn, 1039 N. 22nd St., Milwaukee, Wis. Filed Apr. 3, 1961, Ser. No. 100,068 1 Claim. (Cl. 35-46) This invention appertains to drawing equipment and more particularly to a novel device for facilitating the accurate copying of drawings, photographs and the like.
One of the primary objects of my invention is to provide a device for insuring the proper copying of photographs and drawings embodying an open frame for receiving a drawing board having a sheet of paper thereon or a tablet of drawing paper, the frame having a series of longitudinally and transversely extending cords connected therewith for dividing the device into a plurality of equal squares, so that the photographs, pictures, drawings or other matter placed on the paper and under the cords, as well as the paper itself will be divided into equal squares, whereby a person can accurately copy the pictures or other matter square by square on the drawing paper, and thereby insure that the matter being copied will be in correct proportion and properly located.
Another salient object of my invention is to provide the cords or strings of different contrasting colors, say red, green and yellow, with the colors repeated throughout the entire area of the frame, whereby the picture being copied can be accurately located under the cords and whereby the copier can quickly locate correct squares for drawing in the proper matter being copied.
A further important object of my invention is to form the cords or strings of elastic or resilient material and to secure the cords to the frame under tension, whereby the same can be pushed aside for erasing matter and for filling in spaces normally covered by the cords, the cords under tension returning to their normal correct position after being released.
A still further object of my invention is to provide a drawing copying device, which will be durable and efficient in use, one that will be simple and economical to manufacture and which can be understood and easily used by children as well as mature people.
With these and other objects in view, the invention consists in the novel construction, formation and arrangement of parts, as will be hereinafter more specifically described and claimed, and illustrated in the accompanying drawing, in which drawing,
FIGURE 1 is a top plan view showing my improved copying device in use, parts of the figure being shown broken away to illustrate structural detail;
FIGURE 2 is a bottom plan view of my improved device and showing the use of a drawing board in connection with the frame, parts of this figure also being shown broken away to illustrate structural detail;
FIGURE 3 is a longitudinal sectional view through the device taken on the line 33 of FIGURE 2, looking in the direction of the arrows, and
FIGURE 4 is a view similar to FIGURE 3, but showing the use of a tablet of drawing paper used with the frame in lieu of the drawing board.
Referring to the drawing in detail, wherein similar reference chanacters designate corresponding parts throughout the several views, the letter D generally indicates my novel device for facilitating the copying of drawings, photographs and the like, and the same includes an open frame 5 consisting of longitudinally extending side bars 6 and end bars 7. The bars 6 and 7 can be formed from any desired material, such as metal, plastic or the like, but the same are preferably formed from Wood. The upper face of the frame has secured thereto at equidistantly spaced points a series of longitudinally and transversely extending cords 8 and 9. The transversely extending cords 9 extend across the longitudinally extending cords 8, and as the cords are all equidistantly spaced, a plurality of equal open squares 10 are provided. The cords are formed from elastic or resilient material, such as rubber bands, and the bands are preferably, but not necessarily, of a square shape in cross-section, so as to provide fiat faces for engaging matter to be copied and drawing paper, as will later appear. In securing the cords 8 and 9 to the frame, the same are stretched and placed under tension, for a purpose, which will also later a ear. The terminals of the bands or cords can be secured to the frame in various manners, but as illustrated, I have utilized metal stitches or staples 11 for this purpose.
If preferred, the upper surface of the frame can have secured thereto finishing strips 12 to hide the securing means for the rubber cords and to aid in holding the cords in their correct position.
The frame can either be placed over a drawing board 13, as shown in FIGURES 2 and 3, or a tablet 14, as shown in FIGURE 4. Obviously, the drawing board 13 as well as the tablet are of a size to snugly fit within the frame from the bottom thereof and under the cords 8 and 9. The drawing board can be removably held in place in the frame by the use of swinging latches 15 and the'under surface of the frame and under surface of the board are preferably cut out, as at 16, so that the latches 15 will be received therein, and whereby the frame can lie fiat on a surface.
In use of my device and where the drawing board 13 is utilized a sheet of drawing paper 17 is placed on the upper surface of the board 13 and under the cords 8 and 9. The picture or other matter being copied is then placed on top of the drawing board toward one end of the frame and this picture to be copied is identified by the reference character P.
The picture will be divided into equal spaces by the cords 8 and 9 and of course, the drawing paper itself will likewise be divided into equal spaces. The copier will now copy the picture, square by square, and this will result in the proper location of the various parts of the drawing, or picture, so that the resulting picture will be in proper proportion. Thus, the accurate copying of a picture or photograph or the like is insured and amateur artists can make a presentable copy of anything desired.
As the cords 8 and 9 are resilient and under tension, the same can be pushed aside as indicated in FIGURE 1, and thus spaces normally occupied by the cords can be filled in, to join matter in adjacent squares. Obviously, also, the cords can be pushed aside to make erasures. As the cords are under tension, they will return to their normal position as soon as released.
As shown in FIGURE 4, I can dispense with the board 13 and place a tablet of drawing paper Within the frame.
One of the important features of my invention is to provide means for properly locating and squaring up a picture to be copied and to properly locate correct matter to be copied in the squares on the drawing paper formed by the cords. Thus, sets of the cords 8 and 9 are formed in contrasting colors. Sets of longitudinal cords, now identified by the reference characters 18, 19 and 20 can be colored respectively red, green and yellow, or any other selected colors, and the colors are repeated throughout the width of the frame. Likewise, the transversely extending cords 9 are divided into groups of contrasting colors and cords now identified by the reference characters 21, 22 and 23 can be of contrasting colors, say red, green and yellow, and these colors are repeated throughout the length of the device.
If desired my novel copying device can form a part of a kit placed in a suitable carton with drawing paper and the like. The drawing paper itself can have printed thereon at one side thereof pictures and the like which children can copy.
Where enlargements of a drawing or the like are to be made two frames can be provided, one for receiving the drawing to be copied and the other for receiving the drawing paper. The frame for receiving the paper can be divided into squares of a greater size than the squares covering the drawing to be copied.
Various changes in details may be made without departing from the spirit or the scope of this invention, but what I claim as new is:
A device for facilitating the copying of photographs, drawings and the like comprising an open frame, longitudinally extending equidistantly spaced cords having their terminals secured to the upper face of the frame, a
plurality of equidistantly spaced transversely extending cords having their terminals secured to the upper face of the frame, said transversely extending cords extending across the longitudinally extending cords and defining equal open spaces therewith, a drawing board, a sheet of drawing paper on said board and a picture to be copied on the paper with the paper and drawing received within the frame from the bottom thereof with the drawing and paper under the cords, the lower surface of the board being fiush with the lower surface of the frame, means detachably securing the board within the frame, the equal spaces defined by the longitudinally and transversely extending cords dividing the picture to be copied and the drawing paper into equal spaces whereby spaces on the paper can be filled in with matter copied from the drawing space by space, and said longitudinally and transversely extending cords being divided into groups with the groups being formed of contrasting colors.
