SPECIFICATION forming part of Letters Patent No. 730,015, datedvJ' une 2, 1903.

Application led April A21, 1902l 4the music-holder, the telescopic stand, and

the leg-supporting features. Itis illustrated in the accompanying drawings, wherein- Figure l is a side elevation of a music-stand containing my invention. Fig. 2 is a front elevation of the musi c-holder in extended position. Fig. 3 is a similar view of the same partially folded up. Fig. et is a detail of the leg-supporting device. Fig. 5 is a plan view of the same. Fig. G is a detail of the telescopic portions.

Like parts are indicatedv bythe same letter in all the figures.

A is the music-holder; 13, the upper end of the telescopic support; C,the middle portion, and D the lower portion thereof. Eis a lower part, rigid on the part D and provided with outwardly-proj ecting portions E E. Each of 1 these portions is bifurcated at its upper end to receive the upper end of the legF, which leg is pivoted at G in such bifurcated part. The lu g E' at its bifurcated part is provided with a bearing at X for the leg .F and the upper end of the leg F projects beyond the pivot G.

J is a ferrule arranged to rotate on the part D and having a lower'outwardly-projecting upwardly-inclined ring-like part K, whioh'is slotted at K K. Such slots arel arranged to register simultaneously with'the upper ends of the several legs. At the upper part of the ferrule J is a thumbring M. .When the'ferrule J is turned to the proper position, the slots K register withthe upper ends of thev legs F and they may then be folded up on` the pivots G. When the ferrule is rotated so that the ring K comes beneath the upper end of each of the legs F, the leg is held in rigidposition, because it has two points of support beneath and on opposite sides of the pivot G, one of these at the point Xin the part E' and S2, as indicated.

the other on the upper surface of said ring.

Serial No. 103.841- (No model.)

It is obvious that this ferrule J may be greatly Y varied without departing from the spirit of my invention; indeed all that .is necessary is some portion which moves along or about the part D, so as to comebeneath the leg ends. This rotating or moving part may be locked or held in any desired position; but when the parts have been brought to the position shown in Fig. if the stand is then put in the position shown in Fig. l the weight thrown upon it will tighten the parts; so that the ferrule J will remain securely in the position shown in Fig. 5 and hold the parts together.

In Fig. 6 I have illustrated the friction desus vice whereby the several parts of the tele?y scoping support are secured together. In the lower part of one of these telescoping pieces I'make a series of slots N N, which slots are relatively of considerable length, but not open at their lower ends. part C in this case terminates in the ring O. The walls of the part C between these several slots are outwardly bulged, as indicated in Fig. 6, so asto have a frictional contact with the inner surface of the part in which saidy tube C slides. The tube C is of course pref-l ably of spring material, so thatthis friction al contact is spring-acting, and the parts are thus held together in whatever position they may assume. p

F P are the two p arts of a shelf-like lower ledge, and they are pivoted together at their inner ends to lan inclined central .bar R. This bar is provided on its rear face with a socket R to receive a rigid portion which is inserted` in the upper tubular part B. To this part R are pivoted two links S S, and to the two parts P P are pivoted two`links S S. These links are pivoted together in pairs at Two jointed extension-bars T T are provided, each composed oftwo parts andpivoted at T' T to the central bar R and to the links at S2 and the two parts ypivoted together at T2 T2, as indicated.

The lower end of -the It is needless. to describev the operation of these several parts. It is suiciently shown in'Fig. .3. The form and arrangement of IOC prisinga central bm', a lower ledge, two links pivoted one to the ledge between the bali' mid the end of the ledge and tlie other to the eenti'zl-l ban' intermediate its ends and both pivoted togetl'lei', und 2L jointed extension-beu. consisting ol' two pieces pivoted togetllelfnnd pivoted :it one end to the eenti'ztl ben' :ind :it the other end to the two links, the highest pivot being that which unites the jointed extension-ben' to the eentml bm'.

2. In L music-stand, :L music-holder, coinpi'isin g t central bm', zt ledge, two links and :i jointed extension-bar, all these pivoted t0- gethel at one point so that they may fold, said links connected one to the ledge and one to the Central bar and the extension-bzw.l eonneeted with the eentml bal', the point connecting the links and the extension-ban' being, when the illusie-holder is extended, Yin :i vel'- tieiil line beyond the pivotal eonneetion between tlie link sind the ledge :nid on :L horizontal-l line between the connection between the extension-bzw :nid the central bei' :ind the connection between the link sind the central bai.
