T 0 allwfi'oin'z't may concern V Be it known that LFORTUNATO SonoILLo; a citizen of the United States, resi'ding' in 'Dorchester, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Music Stands; of'whichthe following isa specification.

This invention relates to collapsiblemu'sic' stands. I p

The usual collapsible music stand is pro vided with twoor more memberswhich are adapted to be separated 'or'com'p'letely de tached from each iother and separ'atelycol-f lapsed in order that the stand may liefolded completely; i i I l With such a construction it is quite cornmon to lose one of the detachable members,

or the screw or other fastening meansa'dapted to connect'the'two detachable members;

when the separable members of the'stand are detached and consequently the stand is or may be rendered incapable of further use."

An object of thisinvention is topr'ovide a collapsible music stand wherein all parts generally to improve the construction of" music stands.

Fig. lis a front elevation of" th'e'stand embodyingthe inventio'nJ Fig.2 is a sectional detail=illustratingthe manner of connecting the telescoping tubes of the supporting standard.

Fig; 3 is'a front elevation of themu'sic rack and illustrating various adjustments of the adjustable Inemb'ers'comprising the stand.

Fig.- 4 is a detail similar. to Fig. 3 illuss trating' the rack'in position to be finally folded into its most compact'form.

Fig} 5- is a section g.1. 7 l i.

Fig- 6j-is'asecti0na1' detail of the support,-

ing pedestal" and illustrating the manner" in which the pedestal is locked in expandec position Figr']. is aviewillustrating the stand along-dine 5 5 of spring 14 is adapted to beVsoin'eWhat com with thecompo'nent parts collapsed upon themselves and in readiness for the final folding operation.

Fig. 8 is a V ew of the completely folded and col-lapsed stand As here shown, the music stand embody ingthis invention includes the supporting" standard having the telescoping tubes 10, 11, 12 and 13. The upper tube 13'is adapted to support the note sheet rack while the lower standard 10 is adapted to be secured to andbe supported by the baseor pedestal.- Said tubes 11 through 13 are all secured permanently together against detachment and are arranged in frictional engagement with each other whereby the" standard may be retained securely in any adjustedcondition'the'reofi'.

As shown in Fig. 2, the frictional con nection between the telescoping tubes ine cludes the'helical spring 14, which latter'is disposed within the upper ends of the tubes. Theupper ends: of the tubes are' reflexed inwardlybr otherwise formed to provide an annular inturned lip '15which is adapted closely to conform to the next uppermost tube and retain said spring 14 therein against displacement as the tube'lEZ is drawn ou'twardly. Said tube 11 is also formed witlian abutment disposedbeneath said spring 14:

whereby to hold said spring against any appreciable amount of axial downward move mentwithi'n the tube. As hereshowmmsaid abutment comprises a ring 16 disposed with i in said tube 11." Said ring may be secure d to said tube in 'any suitable'manner'and', as

here shown, is adapted to be soldered ther'eto, the solder being introduced intothe ripheral channel 16 of said tube '12 through an aperture 17 in the tube wall. Saidspr ng 14: is adapted'to be in substantially fric tiona l engagement with the tubelQ'so that" said spring serves to grip said tube 12'snu'gl'y' and thereby hold it securely inf any adjusted position thereof, although said spring is not adapted to'provid'e an undue restriction to the manual collapsing operation of the standard. I

Preferably, although not necessarilymaid pressed in the direction of its length in said outer tube 11' whereby; the "outer and inner tubes are or may "be held against Jundue axial apparent that all of the telescoping tubes of the standard are permanently secured a" justahly together.

The supporting pedestal includes the bracket 20 which is or may be secured about and to the lower end of the lowermost tube 10; and feet 21 are pivotally connected permanently to said bracket by suitable means as the rivets 22, whereby to form a tripodal support for the device. A second bracket 23 is slidably mounted on said lowermost tube 10 above said bracket 20; and links 24 are pivotally connected permanently with said bracket 23 and with said feet 21 intermediate the length thereof and in the same vertical plane with said feet. This arrangement is such that when said bracket 23 is moved along said tube 10 to the upper portion thereof, said feet 21 will be moved into a closed and approximately parallel relation with said tube, and as will also be the case with said links 24, whereby the pedestal and the lowermost tube 10 may be collapsed or folded into a compact formation as illustrated in Fig. 7 I

Said bracket 23 is provided with means. permanently carried thereby, for connecting said bracket releasingly with said tube 10 at the lower portion thereof as indicated in Fig. 1 so that the tripod may be supported securely in extended condition. Said connecting means may include the pin 25 which is received in a recess 26 in said bracket 23 and has an inner end portion which is adapted to register with an aperture 27 in the side wall of said tube 10 and move with in said aperture under the pressure of its spring when in register therewith whereby to lock said bracket 23 releasingly in position. Said pin 25 is or may be provided with an enlarged head 28, or other suitable manual engaging means, which is adapted to be grasped whereby the pin may be withdrawn from said hole 27 thereby to release the bracket 23 from its connection with said tube 10 and permit the tripod to be collapsed.

When the stand is being expanded for use, it is merely necessary to straighten out the feet 21 and said pin 25 will automatically be moved into register with the aperture in and into locking engagement with the tube 10. It will be apparent that with this arrangement the collapsible pedestal or tripod is secured permanently to the verticall) standard comprising the telescoping tu es.

The note sheet rack or support includes bracket 33 with its arms is arranged to overhang the vertical standard comprising the telescoping tubes whereby the better to distribute the weight of a heavy book or the like more or lessequally on both sides of the center of the supporting standard whereby to prevent said standard from becoming unduly overbalanced. Said arms 32 are adapted to engage the hinged member 31 with substantial friction whereby to retain the rack securely in any angular positionto which it may be adjusted.

The rack includes the two L-shaped shelfmembers 35 which are pivotally secured permanently by suitable means as the rivets 36 to said middle plate 30 on opposite sides of the hinged member 31. Bars 37 and 38 are pivotally connected permanently by suitable means as the pins 39 to the upper end of said plate 30 and on opposite sides of the vertical axis of said plate and preferably substantially in line with the pivotal connection of said shelf-members 35 with said plate 30.

Other bars 40 and 41 are pivotally connected permanently intermediate the ends thereof to intermediate portions of said bars 37 and 38 respectively. The lower ends of said bars 40 and 41 are pivotally connected permanently to the upper ends of links 42 and 43 respectively; and the lower ends of said links 42 and 43 are pivotally connected permanently to intermediate. portions of said shelf members 35. Other and locking links 44 and 45 are pivotally connected permanently to the pivotal connections of bars 40 and 41, and links 42 and 43, respectively and said links 44 and 45 are pivotally'connected together and are also connected permanently with said plate 30 and 'slidably disposed in a vertically arranged slot 46 therein. Preferably said links 42 and 44 and 43and 45, areof equal length, which length preferably is substantially equal to the distance between the pivotal connection 36 of said shelf members 35 with said plate 30 and the pivotal connection of said links 42 and 43 with said shelf members 35 whereby a parallelogram is or may be formed. With this arrangement, the various above described bars and links composing the rack may be moved outwardly or inwardly with respect to said plate 36 whereby to enlarge or contract the effective dimensions of the rack and in the various adjusted positions of said bars said shelf-members 35 may be substantially horizontally disposed Said locking links 44 and 45, when arranged in substantially a horizontal line, serve to lock the other adjustable components of the rack in adjusted position; When the rack is collapsed the construction is such that said links 42 and 43 may be moved to a position within said shelf members 35 and in parallel relation therewith, in which position said bars 10 and 41 may be substantially parallel to said plate 30 and may be disposed Within the width thereof as illustrated in Fig. 4. As thus arranged, said shelfmembers 35 may be moved upwardly about their pivotal connections 36 to enclose the various bars of the rack and in folded condition will occupy some such position as that illustrated in Fig. 7.

In the folded position of the rack, the various bars thereof are adapted to occupy only the lower portion of the compartment formed between the folded shelf-members 35.

The stand is ultimately compacted into its final form by moving said folded rack in the direction of the arrow, Fig. 7, so that the collapsed tripod and standard is or may be received Within the upper portion of the compartment formed by the folded shelfmembers 85. As thus finally arranged, the completely collapsed stand will be disposed as illustrated in Fig. 8.

It will be seen that, as arranged, all components of the stand are secured permanently together and the stand may be collapsed into an exceedingly small space.

The structure may be otherwise modified without departing from the spirit of the invention.

I claim:
