STAND FOR HOLDING MANUSGRIPTS OR WRITING OR DRAWING PATTERNS.

Application filed April 18, 1906, Serial No. 312,417. Renewed. May 4, 1908.

To all whom it may concern:

Be it known that I, OTTO TZSOHACI-IMANN, a subject of the King of Prussia and German Emperor, residing at Forst, Lausitz, in the Kingdom of Prussia and German Empire, have invented a certain new and useful Stand for Holding Manuscripts or Writing or Drawing Patterns, of which the following is a specification.

The present invention refers to a stand for holding manuscripts or patterns to be copied by drawing or writing in which the pattern is inserted into a rabbet on the front face of the stand and prevented from rolling up or falling off by a string, which is automatically tightened when the back of the stand is spread off, or opened.

In the accompanying drawing a mode of carrying out the present invention is exemplified, Figure 1 being the stand in partly opened position, Fig. 2 the stand fully opened.

The stand, which can be suitably made of paste board or other suitable material consists of a front face plate a, which for the purpose of allowing of drawing the respective pattern directly on the stand, can be arranged as a slate and be covered for said purpose with a sheet of slate paper, and of a back b hinged to the front at the upper edge by means of strips of linen, hinges or the like. Between both parts a string -c is drawn in such a manner that an endless loop is formed, leavingfree as much of the width of the front plate as possible.

When the stand is folded up, the string c will be rather slack, so that the pattern d can be easily slipped beneath it and inserted into the rabbet c at the lower edge of the plate a. When the stand is spread or opened and for this purpose the back b is turned off, the string c will be automatically tightened and thereby piif'fevent the pattern from rolling up or falling o The stand is secured in the opened position Specification of Letters Patent.

Patented June 2, 1908.

Serial No. 430,855.

by means of a bottom plate f, hinged to the lower edge of the front plate a and resting in opened position against a ridge -g on the inside of the back. For obtaining a better guide of said bottom part and for preventing it from moving, should front and back plates be separated by a shock or the like, a second string loop his drawn through front and back plate and the bottom plate in such a manner that on opening the front and back plates the bottom plate is automatically brought into its correct position. This position is reached when the said string loop has been fully stretched and liesthe one hlalf above the other half beneath the bottom p ate.

The above described stand is very cheaply manufactured and very reliable. A single operation will open or fold it up, a second operation will suflioe for inserting or removing the pattern, thus the stand is very easily manipulated.

Having now described my invention what I claim and desire to secure by Letters Patent of the United States is:

In a stand for holding writing or drawing patterns consisting of a front and a back plate hinged together at their upper edges by means of an endless string loop drawn through both plates, a ridge being provided on the inside of the back plate, the stand when opened, being held in such opened position by means of a bottom plate hinged to the bottom edge of the front plate and leaning on said ridge on the inside of the back plate, said bottom plate being held in its opened position by means of a string loop passing through said front and back plates and said bottom plate, as described.

In testimony whereof I have hereunto set my hand in the presence of two witnesses.

OTTO TZSCI-IACHMANN.
