IMPROVEMENT IN MUSIC-STANDS.

Specification forming part of Letters Patent No. 140,547, dated July 1, 1873; application filed June 4, 1873.

To all whom it may concern:

Be it known that I, OSCAR SoHULzn, of St. Louis, St. Louis county, Missouri, have invented a certain Improvement in Portable Music-Stands, of which the following is a specitication:

My invention consists of a music-stand which is adjustable in height, and which is made to collapse into a compact form of small dimensions, for transportation the supporting-standard consisting of an arrangement on the lazy-tongs principle, and the base and book-support or top frame being expanded automatically by the extension of the standard.

In the drawings, Figure l is a perspective view of my improvement in extended condition, fit for use. Fig. 2 is a perspective view in closed condition, arranged fortransportation.

The base has two end pieces, A, to which are hinged at 1) side pieces B, having hinges b at their middle. To each of the end pieces A is attached a sliding foot or steady-bar, G,

whose end 0 passes through the other end piece A. This arrangement of the base is to allow its expansion at both sides and ends as the lazy-ton gs standard is extended vertically, as shown in Fig. 1. The extensible standard D is formed on what is known as the lazyton gs principle-thas is, a number of bars, d, pivoted together at theends and middle, as shown-so that the standard may be extended and contracted in a straight line. The lower pair of bars, d, are hinged to the end pieces A at a, and the bars (I are hinged to the end pieces E of the head or book rest frame. These end pieces have side bars 6, which slide together in straps e, so as to allow the ends E to approach each other or recede in the same manner as the ends A of the base. Hinged to the end pieces E are. blocks F, having sliding bars f, similar to those 0, and operating in a similar manner. Pivoted to the blocks F at f are bars 01, similar to those d, and at their lower ends arepins g, traversing slots h in the horizontal bars H, to which the bar I is hinged at i. K are brace-rods, hinged to the bars d at k, and to the bars at at k, so that, as the standard D is drawn upward, the ends 70 are drawn toward each other, and the braces force outward the lower edges H I of the book-rest frame.

The operation is as follows: Supposing the stand to be in its closed condition, as shown in Fig. 2, the pieces E are grasped, and by giving a quick upward motion to the hands the standard is extended to some distance. The foot may be then placed upon the base and the book-rest frame drawn up to the desired height. As the standard is extended, its lower bars or levers d draw in the end pieces A of the base, and extend its bearing area, (at the sides by means of the side pieces B, and at the ends by the outwardly-sliding bars 0,) as shown in Fig. 2. At the same time, the lower edges H I of the book-rest frame are forced outward by the brace-bars K, and the foot-rest I of the book being then turned outward the stand is ready for use. To close it up, it is only necessary to fold in the foot-rest I and force the head downward, when the parts automatically assume the position shown in Fig. 2, in which the whole is contained in a small space, and may be easily transported without liability to injury.

I claim as my invention- The combination of expanding base A B G. extension-standard composed of bars 01, and automatically-opening book-rest frame E F H I, substantially as set forth.

OSCAR SOHULZE.
