MUSIC-STAND.

To all whom it may concern:

Be it known that I, MARION F. DoUGi-rnn'rr, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Music-Stand, of which the following is a specication.

This invention relates to music stands, and the main object of the invention is to provide a music stand which can be collapsed and folded up into a compact package which can be easily carried in the pocket.

A further object is to so construct the device that the legs will act as the housing or sides of the box-like package which incloses all of the parts of the stand when it is folded up.

Other objects relate to details of construction which will be brought out in the following description.

Referring to the drawings Figure 1 is a perspective view of the package into which the device is folded. Fig. 2 is a perspective view of one of the folded sections. Fig. 3 is a perspective view of the other folded Fig. 1 is a front elevation of the music stand as extended ready for use. Fig. 5 is an enlarged longitudinal view through the upper end of the supporting post. Fig. 6 is a longitudinal section through the lower portion of one of the sections of the supporting post illustrating the friction grip. Fig. 7 is an end view of the lower end of the lower' telescopic section. Fig. 8 is an end view on a large scale of the folded legs.

The device comprises three legs 1, 2 and 3, each leg being L-shaped in cross section', and the upper end of leg 3 is pivoted at 1 to the upper end of leg 1, while the upper end of leg 2 is pivoted at 5 to the upper end of leg 1, as clearly shown in Fig. 8. It should be noted that there is no pivotal connection between legs 2 and 3. This method of pivotal connection enables the three legs to be eX- tended in the form of a tripod, as shown in Fig. 1, or to be folded together as shown in Fig. 3. A pair of connected links 6 forming a toggle brace is connected between legs 1 and 2, and a similar toggle brace is connected between legs 1 and 3, which toggle braces when straightened serve to hold the legs firmly in extended position, as shown in Fig. 11. A chain 7, seen in dotted lines in Fig. 1,

may be hookedL across between legs 2 and 3 in lieu of the toggle it being ineXpedient to einploya toggle between legs 2 and 3 as the Specification of Letters Patent.

latter swing in planes at right angles to each other when being folded in or out as will be apparent from a glance at Fig. 3.

The legs support a telescopic post by means of three links 8, which are pivotally connected to the respective legs and the eyes 9 on the lower section 10 of the telescopic post. The lower section 10 extends through the opening 11 formed at the upper ends of the three legs 1, 2 and 3 and as shown in Fig. 8 the upper edges of the legs are flared outwardly somewhat so that the opening 11 will be approximately a circle when the legs are extended and will thus give plenty of room for the passage of the section 10. Telescoping within the section 10 is a plurality of sections 12, 13, the upper section 13 having two tongues 14 and 15 which lie at an angle to the section, as shown in Fig. 5. The lower end of each of the telescoping sections 12 and 13 is provided with a series of longitudinal slots s, as shown in Fig. 6, and is bulged at 1G. The slots s form four wings 17 and between cach pair of wings is a U- shaped spring 1S coiled at 19, the two lower ends of each spring 18 being soldered or otherwise secured to the adjacent ends of the wings 17. One of the springs is longer than the other and straddles it, its coil 19 lying above the coil 19 of the lower spring. This construction produces an expansion end which frictionally grips the inner wall of the tube in which it slides with sufficient firmness to prevent the tubes from sliding down when extended.

The music rack comprises a pair of angle bars 2O pivoted at 21, and pivotally supported by the center pivot 21 is a center bar 22 which as shown in Fig. 5 is offset and has a wide slot 23 below the bend and a narrow slot 24 formed in the bend which slots are adapted to respectively receive tongues 15 and 14 of the upper telescopic section 13 to detachably secure the music rack to the post. Pivoted at 25 to the center bar 22 is a pair of short links 2G which in turn are pivoted at 27 to longer links 28, the outer ends of the latter being pivoted at 29 to links 30, t-he latter being pivoted at 31 to links 32 which in turn are pivoted at 33 to links 341-, the latter being pivoted at 35 to the upper end of the center bar 22. The ends of links 32 extend beyond the pivot 31 and are provided with spring clips 3G for retaining the leaves of music. The outer ends of the angle bars 2O are slit for a short distance, as

at 37, as clearly shown in Fig. 2, to permit the links 2S, 3() to be inserted therein, as iudicated in F ig. A, and held from lateral movement with respect to the angle bars 20. A cap 38 is connected by a chain 39 with one of the angle bars 20 at a point near the pivot Q1 so that when the two angle bars are folded, as shown in Fig. 1, the cap 3S may be slipped over the end of the package to hold the two sections of the package together. A similar cap 4:0 is connected by chain 41 to one of the legs and serves to close the other end of the package when the parts are folded. Then extended the cap 3S may also be convenient as a receptacle for holding small articles.

The device, when extended, has the appearance shown in F ig. il. To fold the device the music rack may be slipped olf from the tongues 14, 15 and the two angle bars 2O swung toward the middle bar 22, the links 28, 3() having first been slid out of slots 37, and at the same time that the angle bars 2O are swung toward each other the various links 26 to 3A inclusive are folded in so that the two angle bars Q0 when folded completely together have the form shown in F ig. 2 in which the various links all lie flatly and in orderly form against the bottom of the trough-like section formed. The telescopic sections 1Q, 13 are collapsed into the lower tube section l() and the legs l, 2 and 3 are folded togethell so that when folded they appear as shown in Fig. 3 which forms a package of a size which will just fit within the trough-shaped package shown in Fig. 2 and after being placed therein the caps 88, t() are slipped on the respective ends to hold the two parts together and close the ends thus producing a neat appearing package of most compact form which may be readily carried in the pocket.
