MUSIC-STAND.

Specification of Letters Patent.

Patented Apr. 8, 1913.

Application filed July 2, 1912. Serial No. 707,390. a

To all whom it may concern Be it known that I, ROBERT .W. MILLS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful -Music-Stand, of which the following is a specification.

Th1s 1nvent1on relates ,to music stands of I that type designed to be folded into a comprovements.

pact bundle. I

The object of the invention is to ro-vide simple and efficient means whereby t e legs of the stand may be quickly and securely fastened in an extended posit-ion at any desired angles and may be readily unfastened for the purpose of folding them against the standard of. the device.

Another object is to provide an extensible standard, the parts of which may be maintained in any position to which they may be adjusted without the necessity of utiliz ing set screws or similar devices.

With these and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed outin the claims.

In the accompanying drawings the ,pre ferred form of the invention has been shown.

In said drawings :Figure 1 is a side elevation of a stand embodying the present im- Fig. 2 is an enlarged longitudinal section through a portion of the standard and showing the inner section thereof in elevation. Fig. 3 is a section on line A-B Fig. 2. Fig. 4 is a section of the locking sleeve and the adjoining portion of the standard. Fig. 5 is a plan view of the collar. Fig. 6 is a section on line C-D Fig. 4. Fig. 7 is a perspective view of the ad ustable sleeve. Fig. 8 is an elevation of the stand folded. Fig. 9 is a view like Fig.

4 and showing amodified structure. Fig.

inner faces of the members inw which they project. These runners bear with sufiicient pressure against the adjoining surfaces to hold the members of the standard against accidental displacement relative to one another, although it becomes possible, by exerting sufficientpressure against the mem bers, to shift them so as to extendor reduce the length of. the standard. As shown in-35 Fig. 1 the innermost member of the standard may be provided at its outer end with a reduced neck 5 for engagement with a rack (not shown).

A collar 6 is secured to the lower end of the standard 1 and has ears 7 radiating therefrom, there being a leg 8 pivotall connected to each ear. A sleeve 9. is slidably mounted on the standard above the collar 6 and has its lower end split and provided witha split collar 10 from which extend ears 11. A clamping screw 12 extends through the ears and has a finger piece 13 at one end whereby the said ears can be shifted toward each other so as to clamp the split end of the sleeve upon'the standard 1- and thus hold it against movement on the standard. One end of the sleeve 9 has an outwardly extending annular flange 14 preferably rounded, as shown.

. Aring- 15 is slidably mounted on the standard 1 and has outstanding ears 16 to which braces 17 are pivotally' connected, these braces being also pivotally connected to the le s 8. An annular recess'or counter bore 18 1s formed in the lower end of the ring 15 and is sufliciently large to receive the flange 14 of sleeve 9 when the ring 15-i's ad-' justed againstthe end of the sleeve. .An extension 19 is formed upon the outer face of the ring 15 and has a recess 20 constituting a seat for a ball 21, said recess being inclined downwardly toward the standard so that the balls normally gravitate from the seat and into the counter bore 18.

' It will be apparent that, by placing the stand on one side with the extension 19 thereunder, the ball 21 will gravitate into the seat 20 and the ring 15 can then beadjusted against the flange end of the sleeve 9. This adjustment will cause the braces 17 to push against the legs 8 and swing them to the positions shown in Fig. 1. By then placing the stand upright, the ball 21 will gravitate into the counter bore 18 and as- 11.'

sume a position under the flange 14, as shown in Fig. 4, thus locking the ring 15 to the sleeve 9. By loosening the screw 12 sleeve 9 can be adjusted to any desired position on the standard so as thus to vary the angle of the legs 8 relative to the standard. The legs can be swung upwardly against the standard 1 by reversing the foregoing operation, it being first necessary to incline the rack so as to cause the ball 21 to drop into the seat 20 and to then slide the ring 15 along the standard so as to cause the braces 17 to pull the legs 8 upwardly against said standard. This position of the parts has been illustrated in Fig. 8.

Instead of providing a ball lock such as illustrated in Figs. 4 and 6, the ring 22 may be provided with an opening 23in which a dog 24; is pivotally mounted, this dog being adapted to drop into engagement with the flange 14, as shown in Fig. 9 and thus lock the ring against sliding movement relative to the sleeve 9. By pressing inwardly on the lower end of the dog 24:, the upper end thereof can be shifted out of engagement with the flange 14 and the ring 22 thus slid longitudinally along the standard independently of the sleeve 9.

It will be apparent that by providing either of the constructions herein described it is not necessary to utilize set screws and similar devices such as have heretofore been employed and there is therefore no part likely to get out of order and, through'the formation of rust, and the accumulation of dirt, etc., require the use of special tools for the purpose of looking or unlocking the parts.

thereagainst, a member having an annular flange and carried by and adjustable longitudinally of the standard, a ring slidable on the standard, braces connecting the ring and legs, and gravity operated means for securing the ring to the flange on said member.

3. A music rack including a standard, legs pivotally connected thereto and foldable thereagainst, a flanged member on the standard, a ring slidable on the standard, braces connecting the ring and legs, and a gravity lock for securing the ring to the flange on said member.

4. A music rack including a standard, legs pivotally connected thereto, a flanged member adjustably mounted on the standard, means for fastening said member to the standard, a ring slidable on the standard, braces connecting the ring and legs, and means for automatically locking the ring to the flange.

5. A music rack including a standard, legs pivotally connected thereto, a flanged member adjustably mounted on the standard, means for securing said member against movement on the standard, a ring slidably mounted on the standard, braces connecting the ring and legs, and a gravity lock for securing the ring to the flanged member when the legs are extended to active positions.

6. A music rack including relatively moving members, one of said members having an outstanding portion, and gravity operated means carried by the other member for engaging said outstanding portion to hold the members against relative movement, said means being shiftable out of engaging position when the members are inclined out of normal position.

In testimony that I claim the foregoing as my. own, I have hereto affixed my signature in the presence of two witnesses.
