DRAWING APPLIANCE.

Specification of Letters Patent.

Patented July 7, 1914.

Application filed July 1, 1912. Serial No. 706,992.

T 0 all whomit may concern Be it known that I, Lnoxona BINKO, subject of the King of England, residing at 71 Southampton Row, London, England, have invented certain new and useful Improvements in Drawing Appliances, of which the following is a specification.

This invention relates to improvements in drawing appliances and refers to that type of such appliances in which an outline drawing or the like which it is desired to copy is fixed to a suitable desk, board, or the like, and the paper upon which the device is to be copied is also mounted on a portion of the same or upon another board suitably connected with the first board, a sheet of glass or the like being mounted between the drawing to be copied and the blank sheet of paper in such a position that the person desiring to copy the drawing, after placing the apparatus in a certain position with respect to the light, has simply to look through the glass at the paper upon which he is drawing when he sees the faintly refiected image of the design to be copied apparently projected upon the surface on which he is drawing, so that he has simply to go over the lines of the apparent image with a pencil in order to reproduce the drawing upon the paper.

My present invention relates to an improved construction of device or apparatus of the beforementioned description in which the construction is extremely simple as there are a very small number of parts and the glass or the like can be rapidly placed in position for use and dismounted so that the whole device can be readily packed away in a small flat box. To facilitate this, the device in some cases may be made in such a way that the surface upon which the design to be copied and the blank sheet-s are to be mounted can be folded together so as to greatly decrease the size.

I will now proceed to describe various methods of carrying out my invention with reference to the accompanying drawings, in which Figure 1 is a perspective view of my invention. Fig. 2 is a fragmentary plan view of the same. Fig. 3 is a fragmentary perspective view of a detail. Fig. 3* is an end elevation of the same. Fig. 4: is a fragmentary perspective view of a slight modlfication. Fig. 4 is a perspective view of a detail of the same; and Fig. 4 is a perspective view of a detail.

Referring to the form of the device shown at Figs. 1 and 2 a and b are two boards which are attached together by strips 0 of brass or other suitable material by means of pins or screws d passing through the holes in the strips 0 and into the sides of the boards a and b, the attachment being such that the boards a and b are held at a short distance apart so as to leave a gap 0 between.

is a sheet of plate glass or the like which bound around the edges 9 to form a kind of frame or if desired a wood or metal frame may be provided. This sheet of glass is of such size and thickness that it just fill-s up the gap 6 so that when it is inserted into such gap it stands upright and firmly in positlon.

In using the device, a sheet 72. with the design to be copied is pinned upon the board a and a plain sheet of paper is upon the board b. Upon looking through the glass f on to the sheet is the apparent image of the design on the sheet h is shown projected upon the sheet is and it is simply necessary to go over the lines of the image with a pencil or the like and reproduce the same on the sheet is. After the apparatus has been used it can be immediately stowed away into a small compass if desired by removing the glass f from its position in the gap 6 and laying it upon one of the boards and folding the other board over on to the other side of the glass.

Referring to the forms of the device shown at Figs. 3 and 3 the boards a and b are connected at a suitable distance apart by means of two angle pieces 1' of metal or other suitable material. These are attached by suitable screws, pins or the like at in such a way that the boards a and b are held at a suitable distance apart leaving a gap e between them. It will be seen that the angle pieces rare so attached that they extend for a short distance beneath the boards a and b.

.By this arrangement when the glass f is in position if the whole apparatus be raised there is no possibility of the glass 1 dropping through.

Referring to the form of the device shown at Fig. 4, Fig. 4 and Fig. 4., in this case one of the boards I) has attached thereto a fitting such as that shown detached at Fig.

4". This fitting which is of springy metal comprises a strip .9, a projecting lug t and a perforation it. This fitting is attached by means of screws 11 to the board I). The board a is provided with a projecting pin w. In order to set up the apparatus it is simply necessary to spring the fittings 8 coming on each side of the board I) apart and to engage the corresponding pins w on the board a in the perforations u. The boards a and b are then in a suitable position for inserting the glass f as explained with reference to the other forms of the device. I

It will be understood that the methods of constructing the apparatus or device just described are given merely by way of example as the construction may be varied to a very considerable extent without departing from the principle of the invention. Any suitable bottom board or combination of boards may be employed and any means for holding the glass or other equivalent in a suitable position, on or in connection with the said board or boards.

What I claim as my invention and desire to secure by Letters Patent of the United States of America is 1. In a drawing appliance, a base comprising two boards, a pair of fittings connecting said boards along opposite side edges leaving a space between the ends thereof, each of said fittings being provided with an angle portion extending inwardly beneath the space between said boards, and a sheet of lass fitting the space between said boards, and resting on the angle port-ions on said fittings.

edges of the other of said 2. In a, drawing appliance, a base comprising two boards, pins projecting laterally from the side edges adjacent the proximal end of one of said boards, a pair of spring fittings secured at one end along the side edges of the other of said boards and provided with perforations at their outer ends for engaging said pins to connect the boards so as to leave a space between the ends thereof, angle portions extending inwardly from each of said fittings beneath the space between said boards, and a sheet of lass fitting the space between said boards and resting on said angle portions.

3. In a drawing appliance, a base comprising two boards, pins projecting laterally from the, side edges adjacent the proximal end of one of said boards, a pair of spring fittings secured at one end along the side boards and provided with perforations at their outer ends for engaging said pins to connect the boards so as to leave a space between the ends thereof and deflected free ends beyond the perforations for encountering said pins and moving said fittings into engagement therewith, angle portions extending inwardly from each of said fittings beneath the space between said boards, and a sheet of glass fitting the space between said boards and resting on said angle portions.

In testimony whereof I aflix my signature in presence of two witnesses.
