GRAPHIC nfinnsmxirarron App1ication :filed July 25,1929." vserial No. 381,334,
This invention relates to. graphic repie sent-ation and has particular relation to the production of curves. p
Inthe production of graphics by coordi- .5 nates, the useiof curves is common. These curves are usually drawn'on crosslined paper. When additional or changed data make changesin the representations necessary, the operator must draw in the additional line or lines or erase the incorrect, lines and replace them with new lines. With the use of ink, changes'are diflicult because of the resistance of the ink to removal and the liability of tearing the sheetupon which the graphic representation isbeing placed. I
It is to obviate the above difficulties in the production'of graphicrepresentation that my present invention is directed and The primary obj ectof my invention is the production of an improved and" rapid means of graphic representation which may be quickly and easily changed when such change is desired. o
Another object of this invention is the provisionof a device for the representation of curves in which a flexible memberiis used to represent the curve.
Another object of this invention is the provision of a graphic representation device having a board, rowsof holes in the board, pins to go into the holes in the board, and a flexible member to connect the pins together.
Still another object of the invention is the provision of a. graphic representation device having rows of cross lines and lines of holes corresponding to the lines with pins for the,
holes and a flexible member to connect the pins together. 7 I v I A still further object is the provision of such a graphic representation device having a blackboard and a white flexible strip of cardboard for indicating curves on the board.
Another and still further object of the invention is the process of laying off a series of points on a board of'color characteristics to have little effect upon the active surface or" a photographic paper, then connecting the points with a flexible strip of color characteristics to effect the active surfaceof a phothe line3.3 of Figure 1.
:1 direct photograph of the board.
- Referring to the drawing wherein, I have illustrated an embodiment of my invention; Figure 1 is a perspective view illustrating the construction ofthe invention. Figure 2 is a view illustrating the photo graphic reproduction of the board as used.
Figure 3 is a detail cross sectionalview' on Figure 4 is a detailview of a portionot one "curve indicating strip.
Figure 5 is a viewsimilar to Figure 4-, but of another strip. a I
In the drawings, the same or similar parts aredesignated by the same reference character/ I In Figure 1, I have shown a board 10 having an ordinate line 11 and an abscissa line 12. r
In carrying out my invention, I provide a flexible member to indicate the curve showing the graphic representation. This I have exemplified in the flexible bristol board strip .13 shown in Figures 1 and 3.
-To hold the strip 13 in place, I have pro- 'vided means for coaction between the board 10 and strip 13. The means in thelembodiment illustrated for holding the strip in place, comprises the holes 14 and the pins 15. These holes 14 are] preferably located on cross lines on the board shown' at 16and 17 the lines 16 being horizontalv along which abscissae aremeasured and the lines 17 extending at right angles thereto and along which ordinates are measured.
tographic paper and .finally the makingiof Theboard 10 is preferably red or black or of some color which will have little or no eflect upon the sensitive coating of a photo- 1 graphic paper. The flexible curve indicating member 13 preferably has color characteris- Indicia of the ordinates and abscissa may tics different from those of the board 10 and v i be marked adjacent the origin lines to facilitate the laying off of values for the graphic s representation. The-datafor the ordinates and abscissae being before the operator, the
oints corresponding thereto are found and indicated in some way as by marking them on the board or by placing the pins in appropriate holes. In order to secure the flexible strip 13 in place, ins 15 are placed in appropriate holes in the rd in a manner to contact with the flexible drip 13 to hold it securely in the desired position. The pins 15 are preferably made of the color characteristics of the board so that when the board is photographed, the pins will not be apparent. I
When the points to be located are all placed in their roper places and the flexible member has method, is the photographing of the whole face of the board.
An advantage of the invention is that the board with its curve or curves may be photographed at any time and the material used again. As many photographic copies may be made as are necessary. The curve may be extended by using a longer flexible member or by normally placing a paper or other mask, of the color characteristics oi the board, over the end of the plotted curve. This I have indicated by the dotted lines on the board at 18.
As more points are plotted, the mask is.
3* moved to expose more of the curve. By using such a mask having the color characteristics of the board, the curve appears in photographs as ending at the edge of the mask.
It may be found to be desirable to have 5 more than one curve illustrated. This may be done in any suitable manner as, when the strips are used, by cutting away half of each strip as shown in Figures 4 and 5. The strip 13 may be cut away on its top as at 13 and 4. I the curve indicating strip 19, on its bottom as at 19. The view from above, either from the eye or in a photograph does not show the cut away rtion prominently and with proper li ht, it would not show at all.
W ile I have illustrated and described in detail an embodiment of my invention, I desire to have it understood that I do not limit myself to the exact showing and that modifications and changes as to the construction,
type and color of details may be made without departing from the spirit of my invention and within the scope of the appended claims.
Havin described my invention, What I claim an desire to secure by Letters Patent bl. t- Z- 1. A graphic representation device comprising a board, a thin resilient member, means for holding the thin resilient member on the board to give a graphic representation.
2. A graphic representation device comprising a board, holes in the board, a thin resilient member, means, including pinsto insert in the holes for holding the thin resilient member on the board to give a graphic 0i representation.
een applied, the next step in the 3. A graphic representation device comprising a black board, holes in the board, a light colored, thin, resilient member, means including ins to insert in the holes for holding the thin resilient member on the board to give a graphic representation.
4;. A graphic re resentation device comprising a board, hoes in the board, a narrow, thin strip of resilient material, means including pins to insert in'the holes for holding the thin resilient strip edgewise on the board to give a graphic representation.
5. A graphic representation device comprising a board, the board having coordinate lines thereon, a thin resilient member, means for holding the thin resilient member on the board to ive a graphic representation.
6. A process or producing graphic represensation comprising the markin off of points on a board at given distance therefrom relative to an origin, the connection of these points with a resilient strip member and the photographing of the board with the strip thereon.
' A process for producing graphic representations comprisin the placing of pins at points on a board, t e light from which has little effect upon a photogra hic paper, the securing of a resilient strip, 0 a colorto effect a photographic paper, to the pins, and the 9 making of a photograph of the board and strip, directly onto a photo rapliic pa r.
In testimony whereof, I ereunto ag X my signature.
