Music-STAND.

To all whomc' may concern.'

`Be it known that I, ANDRE-w Zoirnifo, a citizen of the United States, and a resident of Passaic, county of Morris, and State of New Jersey, have invented certain new and useful Improvements in Music-Stands, of which 'the following is a, specification.

This invention relates to an improved music stand which is adapted to be, for the most part, contained in' one unitary structure which is adapted to be extended when required for use, and `also to be nested or assembled when it is not in use, so that a small compact article is presented when itis not extended.

The inventionfurtherconsists of a music stand of this kind which consists of a casing which formsa part of the music `stand in addition to its function as a casing, and has' feet at the bottom and a stem at the top` which can be projected fromthe casing,

preferably simultaneously, and similarly simultaneously withdrawn within the casing when desired.

The invention further consists of a casing which is adapted to receive the leaf or sheet holderwhijch supports the music, which, for this purpose, is made so that it can be folded.

The invention further consists of certain details of construction which will be hereinafter more fully described and finally embodiedin the claims.`

rThe invention is illustrated in the accompanying drawing, in which Figure 1 isa front view of the device with the casing shown in section. Fig. 2 is a side View, with the parts assembled, illustrating the compact package formed by this devicewhen the parts are fully assembled. Fig. 3 is a detail, on an enlarged scale, of the sheet music holder, this view illustrating the hub portion with its front plate removed `and the fingers-of the bottom section on the left hand side of the figure also removed.V Fig. 4' is a perspectiveview of the bottom end of one of the fingers. Fig. 5 is a section taken on Ythe plane of line 5 in Fig. 3. Fig. is an en larged section ofthe bottom section of the sheet holder, taken on line 6 in Fig. 1. Fig. 7 is a section of the casing online 7 `in Fig. 1.- Fig. 8 is a detail view showing the top part of one of'the'legs and the gear for operating it. Fig. 9 is a sectionon line 10 in Fig. 1, and Fig. 10 is a section to illustrate one form of swinging guide .for the legs, taken. on a plane indicated byline lO'in Fig.1 y

'lfhe `music stand is made up of members which are extended whenthe stand is to be used, the preferred forni being tohave such extensible. members mounted in a casing which forms a part of `the support, inthe drawing the casing 10 being shown, this casing being preferably tubu-lar and usually made inthe form of a cylinder. To properly supportthe eXtensible members I provide a frame which is securely fastened within thecasing, theflower part of the frame acting. as a .support for the legs, the frame including guides or slide-ways 11 which are channeled, as at 12,to receive the legs 13, these legs being `adapted to be withdrawn within the casing whenthe device is folded,

these gears being preferably all actuated from a singleworm 17 on ashaft 18, which Y shaft is mounted with one end in the bearing in the bottom plate 19 and' passes through the upper platefQO and is rotated by means to be hereinaftermore fully described. In order to permit the divergence or separation of the bottom parts of the legs when they are extend-ed I provide swinging 'guides 21 mounted in the bottom. platey 19 and adapted to swing outward when the legs are divergent, this being possible by reason of vthe extensions 22 on the legs, each of these extensions having a curved top 23,'each extension being pivoted, as at 24, to' its respective leg, and when the curved portion is engaged by the gear it is swung so that its and form a substantial and positive support- .for the ,music stand.

The shaft 18 can be rotated inv any desired way,but I preferto rotate it byV means of gearing, the gear 25 being mounted on the shaft 18 `and the` gear 26 beingplaced on a Ashort shaft `27 mounted in the bearing 28,

whichlispreferably part lof the frame, and a handle 29 is the means by which the short shaft 27 is turned. VThe particular form of handle I.l lhave illustrated comprises the crank handle 29 pivoted at 8O to the boss81 i on the shaft 2'?, so that when not in use the handle can be swung so that it extends into a cut-away part'32 in the casing and the whole surface is substantially flush.

When the shaft is tobe rotated the han-V dle is swung upward, Vthe stud 83 enters the opening 34 in the collar 81, and, the handle being'in the position illustrated in Fig. 9, the" shaft can be rotated, since the handle por@y tion 29is swung outside the surface ofthe casing. 1

shaft 18 is rotated toproject the legs fromV the bottom of the casing the stem 35 is projected from the top. The sleeve 86 .1s mounted in a spider 39. which is preferably made as 'shown in Fig. 7, having three spaced arms so as to leave a space yfor the reception of the folded sheet or music holder to be described hereinafter.

` lIn orderto permit a more elevated position 4for holding the music in such position as is desired, I provide an extension 40 which is usually made so that it is frictionally h eld in the stem, such asby means ofthe spring lips 41 illustrated in Fig. 5, the top part of the Vextension being adapted to support the sheet or music holder and is usually provided with a vlip 42'which enters a socket 43 on the rear of the-hub yor central portion of lthe sheet holder.

The sheet holder is made foldable,V the preferred form comprising a hub with a rear plate'44 and a front plate 45, between these being arranged the center plate 46. Fingers 47 are made with transverse studs 48 which 'tit'. into openings Y49 in the front and back plates and rest in recesses in the middle or center plate 46, the' center plate'b'eing cut n bottom of music books or the like, which.

away so as to provide stops 50 which limit the outward swinging of the fingers,lbu't permit these fingers to be nested, as in Fig.

3, or they vcan be extended Vto form afanlike structure, as shown' in Fig. 1. On each side ofthe sheet holderare the bottom sections which act to support the supports or bottom sections are preferably l' made so that they fold over and inclose the folded lingers, as shown in dottedl outline in Fig. 1.

In Figs. 8 and 6 I show this part of the device more indetail, each bottom section being mounted on a pivot 51 and having a' stidening rib 52 with a lipbent around to form a knuckle or eye through which the pin 51 passes. Secured to the stitiening or bottom rib 52 is a back plate 53 which is lLshaped and has an additional bottom section 54 hinged thereto, and front section 55 is hinged to the front ofthe additional bottom section, these parts being adapted to be vfolded,ras shown in dotted outline in c Fig. 6, andwhen thus folded can be swung upward from the position shownin full lines in Fig.y 1 to the position shown in dotted lines' in the samefigur'e, and when so folded can be slid into the casing in the position shown at a in 7, for `which reason I prefer to eliminate one of the arms of the'spider 89. i

,This Vstructure also permits -the extension 40 to be slid into placeres at?) in Fig. 7, so that when thus assembled and the shaft 18 turned to withdraw the stem 35, a suitable L:

lid, suchfas the lid-56, can beV closed over the upper end of the casing. 1' i i ,Y It will be evident from this description that a complete music stand can be quickly extended by turning the handle 29. and when'it is no longer desired for use all that it is vnecessary to do is to' fold upthe sheet holder at the top, slip it into its place in the casing, `and the extension 40A is then slipped down into its place in the casing, thefhandle v29 rotated to cause the withdrawal of the legs and of the stem, and-thelid 56 canthen be put in position and a-compact package is the result which can be carried inthe usual jmusic case or music roll. Y i v If desired, the bottom part of the casing can be closed by a suitable cover 57. shown in'dotte'd outline at the bottom'of Fig. 2.

y Slight changes and gmodiicationscan be made inthe details ofconstruction without departing from the scope -of theinvention. I claim:

1. A music stand comprising a lcasin,.f,ga

stem adapted'to proiectfrom the top of. the

casing, feet adapted to bev projected from the lbottom of the casing, `mechanism for projectingthe stem and the feet from the casing. said' means alsoincluding a structure which locks the stem" and legsin their adapted to :be detachably secured.' to the top of the stem. f T if 2. A music stand comprising a tubular casing, arframe' 'in the casing,flegs sliding 'in the frame, a stem sliding in the frame,

operatingmeans for simultaneously project- Ving the stem and the legs from-:the casing, the structure including means forjlockingthe stem and legs in position after they are Vprojected positions. and V"a sheetv holder proiected. and a ysheet holder adapted to .be

detachably secured tothetop of the stem.V 1

3. A music stand comprising a tubular casing, a frame in the casing, a shaft rotatable in the frame, a stem sliding in the frame and held against rotation and being in screw-threaded engagement with the screw thread on the shaft, legs sliding in the oasing, an operative `connection between the legs and the stem so that when theshat is rotated the legs are moved and the stem is slid, and a sheet holder on the top of the stem. i

4. A music stand comprising a tubular Casing, a frame in the casing, a shaft having a screw-thread thereon and also having a worm, a stem slidable in the casing but held against rotation therein, said stem having a screw-thread to engage the screwthread of the shaft, legs slidable in the casing, gear wheels engaging ratchets on the legs, said gears being mounted in the frame and being operable by the worm on the shaft, whereby when the shaft is rotated the stem and the legs are slid in unison.

5. In a music stand, a sheet holder comprising a hub, the hub having a rear plate, a central plate and a front plate,rthe front and rear vplates having openings therein, the central plate having recesses in line with said openings, stops between said recesses, fingers having transverse studs to enter the opening in the front and back plates and having stops to engage the stops on the center plate to limit the swinging of the fingers, whereby the fingers can be nested or can be sepa-rated to form a fan-like structure, and bottom plates having mea-ns co-acting with means onthe hub for limiting the outward movement of said bottom plates.

6. In a music stand, a casing having a frame therein, swinging guides, legs slidable in the swinging guides and in the frame, ratchet teeth on the inner faces of the legs, an extension on each leg having a curved top, the extension having ratchet teeth, gears in mesh with the ratchets of the legs, a worm in mesh with the gears, the extension of each leg being pivoted to its legso that when the extension is in engagement with its respective gear the legs and their guides are swung and thus placed in divergent supporting position.

In testimony that I claim the foregoing, I have hereto set my hand, this th day of September, 1920.

ANDREW ZONDLO.
