JOHN HR-ABAK, OF KERMIT, NORTH DAKOTA, ASSIGNOR, BY MESNE ASSIGNMENTS, OF ONE-HALF TO L. A. O. KNOPH, OF NOONAN, NORTH DAKOTA.

MUSIC-STAND.

To all whom 2'25 may concern:

Be it known that I, JOHN HRABAK, of Ker-- mit, in the county of Divide and State of North Dakota, have invented certain new and useful Improvements in Music-Stands, of which the following is a specification.

My present invention relates to folding music stands, my object being to provide a stand which may be conveniently and readily folded into a compact structure of substantially reduced size, whereby to render its transportation more ready and convenient.

In the accompanying drawings which illustrate my invention, Figure 1 is a front elevation illustrating the music stand unfolded and in operative position; Fig. 2 is a side elevation, the lower leg portion being broken away; Fig. 3 is an enlarged vertical section through the intermediate portion of the stem of the stand; Fig. 4 is a detail transverse section taken substantially on the line H of Fig. 3; Fig. 5 is a front elevation, on an enlarged scale, of the upper folding music frame; Fig. 6 is a bottom plan view thereof; Fig. 7 is a front elevation of the music stand folded for transportation; Fig. 8 is a detail vertical section through the lower stem portion and the leg guide; and, Fig. 9 is a transverse section taken substantially on the line 99 of Fig. 8.

Referring now to these figures, the main upright stem of my improved stand embodies an intermediate section or main handle section A, an upper section A and a lower section A-, the intermediate section A having a handle a and a tubular portion a into which the lower end of the upper section A is telescopically disposed. As seen clearly in Fig. 3, the lower end of the intermediate section A is bifurcated and between the bifurcations is pivoted the upper end of the lower section A at a the lower end of the lower section A having a circular enlargement a to which are pivoted the depending radial diverging legs B.

A main operating lever C is intermediately pivoted at c to the intermediate stem section A and extends substantially at right angles thereto, this lever being provided with a handle 0 at one end and an upwardly extending lug 0 between the handle 0 and its pivot 0. Pivotally connected to the lugs 0 at its lower end, and to a port-ion of the upper stem section A, at its upper end, is

a connecting link C, whereby when the handle 0 of the lever C is depressed from the position shown in Fig. 1, the upper stem section A is caused to lower and extend downwardly within the tubular portion a of the intermediate stem section A. In like manner a connecting link C is pivotally united at its upper end to the opposite eX- tremity of the lever C and is pivotally united at its lower end to the lower stem section A at a point intermediate the ends of the latter, whereby when the handle 0 is depressed and the upper stem section A lowered as just described, the lower stem section A will be moved angularly upon its pivot a all as clearly seen in Fig. 7.

The lower end of the lower stem section A is provided with a longitudinal bore into which the stem 5 of the leg guiding block B is projected, this block B being disposed within and between the legs B below the lower end of the stem section A and being provided with U-shaped members 6 surrounding the several legs whereby when the block is lowered with respect to the stem section A the legs B will be drawn inwardly toward one another. In order to effect this movement simultaneously with the folding of the main stem section, a link B is pivotally connected at its lower end to the block B and at its upper end to the connecting link C at a point intermediate the ends of the latter, whereby when the lower stem section A is moved angularly to the position shown in Fig. 7, the block B will be forced away from the lower stem section A and the legs B at the same time drawn inwardly to the position shown in dotted lines in Fig. 8.

The upper end of the stem section A is rigidly connected to the central inclined bar D of the inclined music holding frame embodying side portions D and D which are pivotally connected at (Z to the upper and lower ends of said central bar D. To the lower portions of the frame sides D and D are pivotally connected links (Z and (Z these links being pivotally united at their inner ends in longitudinal alinement with the central bar D by means of a member (Z to which the upper end of an actuating link D is pivotally connected, the lower end of said link (Z being pivotally connected at (Z to the upper end of the intermediate stem section A whereby when the upper stem section A is lowered, the connected ends of the links (Z and (P will be forced upwardly, folding the frame sides D and D forwardly upon one another, as indicated by the arrows in Fig. 6 and as particularly shown in the folded position in Fig. 7.

Thus from the foregoing it will be seen that both the upper and lower portions of the main stem are folded with respect to the intermediate portion, and the legs and sheet holding frame folded at the same time, all of these movements being effected through connections from a single actuating lever and being such as to produce a compact structure adapted to ready and convenient transportation as desired.

I claim 1. In a folding music stand, the combination of a main stem embodying an intermediate section, an upper section having a movable connection with the intermediate section and carrying a folding sheet supporting frame at its upper end, and a lower section also having a movable connection with the intermediate section and carrying folding legs at its lower end, and a lever having connection with the intermediate section and provided with connections whereby to fold all of the parts upon a single movement thereof.

2. A folding music stand embodying an upright stem having an intermediate por tion, an upper portion slidable with respect to the intermediate portion, and a lower portion pivoted to the intermediate portion, a transverse lever intermediate-1y pivoted to the intermediate stem portion, and links connecting the upper and lower stem sec tions with portions of the said lever upon opposite sides of its pivot whereby to cause movement of the upper and lower stem sections when the lever is rocked upon its pivot.

3. In a folding music stand, the combination of a vertical stem embodying an intermediate section, and upper and lower sections, a folding music frame carried by the upper section, the lower section being pivotally connected at its upper end to the lower portion of the intermediate section, a lever carried by the intermediate section, a connecting link between the lever and the lower stem section whereby to cause the latter to swing upwardly toward the intermediate section when the lever is actuated, depending divergent legs pivotally connected at their upper ends to the lower stem section,

a guide block disposed within the said legs and having guide members encircling the stem section and thus draw the legs together when the lower stem section is swung angularly upon the intermediate stem section.

4. In a music stand, the combination of an upright stem embodying an intermediate section, a lower section carrying supporting legs, and an upper section having a sliding telescoping engagement with a portion of the intermediate section, a lever carried by the intermediate section, a link pivotally connecting the lever with the said upper section whereby to move the same downwardly to telescoped position within the intermediate section, an upper music supporting frame embodying a center bar rigidly connected to the upper end of the upper stem section, and side portions pivotally connected to the said center bar, links pivotally connected together at their inner ends and having their outer ends pivotally connected to the said side portions of the music frame, a member pivotally connecting the said inner ends of the said links, and an actuating link pivotally connected at its upper end to the said member and at its lower end to the intermediate stem section whereby when the upper stem section is telescoped, the side portions of the music frame will be folded against one another substantially as described.
