UNITED STATES PATENT OFFICE.

RICHARD GHOINANUS, OF BERLIN, GERMANY.

ADJUSTABLE FRAME FOR PICTURES, 84C.

SPECIFICATIONforming part of Letters Patent No. 317,510, dated May l2, 1885.

' Application tiled July 28, 1884. (No modelf) To all whom it may concern,.-

Beit known that I, RICHARD GHOINANUS, a subject of the King of Prussia, and a resident of the city ot'Berlin, Germany, have invented a new and useful Improvement in Adjustable Frames for Pictures, Looking- Glasses, Src., of which the following is a i'ull and correct speciiication.

My invention relates to easels or portable stands for pictures, maps, mirrors, and other articles.

In the accompanying drawings, which illustrate the invention, Figure l is a back view, and Fig. 2 a vertical section, ot' a stand embodying my invention, while the other iigures represent details and modifications.

The invention consists in a special ap pliancc or mechanism for connecting the two parts A A of the frame which holds the picture, mirror, or other article.

Instead ot' a pair of clamps mounted on a rod and held together by a sprin g, and a folding sta-y or leg, as frequently used for the purpose of holding together the two halves or parts of the frame and supporting'them, I employ a spring, B, pivoted to the halves A A of the frame, and capable of being iixed in its upright position (perpendicular to the plane of the frame A A) by any'suitable means. The plates A A are connected with the extremities ofthe spring-stay B by means of hinge-joints C C,'which allow the stay B to be placed perpen'dicularly to the plates A A, as shown in Fig. 2, or turned down, as shown in Fig. l. The elasticity ot' the stay B tends to draw theclamps A A against each other, so that a'plate, mirror, or sheet placed between the turned-up edges ofthe parts A A will be tirmly gripped by the same.

In order to x the stay in its upright position, the lower hinge, C, is constructed as shown in detail by Figs. 3 and 4, Fig. i representing the upright position, and Fig. 4. the folded position. The part of the stay B situated in the hinge-piece C is surrounded by a helical spring abutting with its upper end against a collar ofthe stay B, while the lower end is fixed to the hinge-piece. The extremity oi' the rod forming the spring-stay B has a projection, c, which fits into a recess, d, of the hinge-piece G, and is drawn into the same by the helical spring, after the stay has reached its upright position. The helical spring iucloscd in the hinge-piece U, therefore, only serves to tix the stay in its upright position, while the plates A A are held together by the elasticity of the stay B. In the modiiied form represented by Figs. 5 and 6 the hingepiece is replaced by the guides c e, andthe wire or rod forming the stay is bent at f and j". Ii' the stay is turned into the upright position represented by Fig. 5, the parts fj" enter the dished parts g g of the plate A, and thereby tix the stay in its upright position.

What I claim isl. In stands for holding pictures, mirrors, and other plates, shcets,or frames, the combination ofa pair of clamps adapted to hold the plate or frame on opposite sides, with a spring pivoted to the said clamps aud adapted to draw the same together, substantially as described.

2. The combination ot' clamps A and A with spring B, hinge-piece C, hinge-piece G, and mea-ns for securing the spring B in its standing position, substantially as described.

In testimony whereof I have signed my name to this specication in the presence ot' two subscribing witnesess.

RICHARD GHOINANUS.
