SPECIFICATION forming part of Letters Patent No. 280,432, dated Ju'iy 3, 1883,

Application iiledJuly 29, 1882. (No model.)

To all whom it may concern,.-

Be it known that I, WILLIAM S. VVOEDEN, of Kearney Junction, in the county of Buffalo and State of Nebraska, have invented certain new and useful Improvements in Drawing Apparatus; and I do hereby declare that the fol-V lowing is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to apparatus or devices for free-hand perspective drawing, and has for its object to provide simple, inexpensive, and efficient means whereby this art may be readily and quickly acquired.

In the drawings, Figure l is a perspective view of the apparatus; Fig. 2, a side vieur showing the manner of using; Fig, 3, a vertical sectional view, and Fig. 4 a top view.

Referring to the drawings, A designates a rectangular frame, forming the front of the camera. From the four corners of frame A extend rearwardly convergent bars or pieces B B and C C, the top pair of which being designated by the latter letters. To the ends of the convergent bars lis secured a rear rectangular frame, D, forming the back of the camera. The inner rear edges, E, of the side bars, F F, of frame A are formed with vertical grooves G, as shown, in which is placed a front glass plate, H. In rear of the latter is placed a sheet of perforated paper, I, the whole being secured in place by spring-catches J on I side bars, F F, the catches preferably consisting of a coil, K, having a projecting arm, L, and a turned-over end, M. y

The operation and advantages of my invention will be readily understood. In practice,

rear frame, D, and, with a pencil in the right hand, the landscape or object seen through the glass and paper is drawn on the latter. The landscape or object is seen in reduced true perspective, and, as the eye follows the outlines, the pencil need only follow the eye. Thus a true perspective of any object may be quickly obtained, and, by altering the distance between the object and apparatus by removing the latter, the size of the drawing will be increased or diminished, as desired.

IVhen one side of the perforated paper has been drawn on, it may be turned over and the other side utilized, as the drawing on one side doesnot in the slightest degree interfere with the drawing on the other. The paper may then be separated from the frame, and, if desired, the landscape may be reproduced or enlarged on drawingpaper with a pantograph. In this manner unskilled persons can readily produce a perspective drawing and the eye is trained in this art.

I claim as newl. rIhe combination, in a perspective-drawing apparatus, with the front frame, carrying rest, as set forth.

rIhe combination, in .a perspective-drawing apparatus, of the rectangular front frame, having the side pieces grooved and provided with spring-catches, and provided at its four corners with convergent rearward-extending rods or pieces, and the rear rectangular frame or rest, as set forth. y In testimony that I claim the foregoing as my own I have hereto. affixed my signature in presence of two witnesses. the forehead is placed against the top rail of f WILLIAM S. IVORDEN.` Witnesses:

FRANK MALoNE, SAM M. NEvINs.
