In the drawings, 12 designates the' standard, and 13 the sheet-music support. of a music xrack, of well known construction, the standard beingsupported in a vertical position by a tripod, and the support 13 inclined relative'to'thestandard. 1 v The attachment :of my invention com prises a clamp having means for separable engagement withthe standard 12, a shelf 20, and means connecting the shelf with the clamp,sa id parts being so arranged that when the clamp is engaged with the standard,rthe shelf extendslhorizontally beside the Application filed mm 7, 1928.

standard, as indicated by Figure 1, means being provided for laterally supporting an accumulation of reserve music, either in sheet, book, or folio form, deposited on the shelf.

The clamp is adapted to embrace and be contracted on the standard 12, so that it may be confined at any desired height on the standard. The clamp shown by Figures 2, 5 and 6, is an elongated loop including a compressible inner neck portion 1%, bearing on the standard, sideportions l5 projecting from-the standard, and an outer neck portion 16, having an car 17, in the sides of which are grooves 18, the purpose of which will be described. A clamping screw 19, havinga shoulder bearing on one of the side portions 15, and a threaded portion engaged with a tapped orifice in the opposite side portion, as best shownby Figure 6, isadapted to draw the side portions inwardly, and thus compressthe neck portion 14 on the standard, so that the clamp is positively engaged with the standard and is unmovable thereon when the screw is tightened.

Thezclamp shown by Flgure 8, differs from the clamp above described, only in that the compressible neck portion, designatedby 14a has a free end which overlaps a side portion 15a and is engagedby the clamping screw 19.

The clamp shown by Figures 9 and 10 will be described later; The shelf 20, shown by Figures 1, 3 and 4, is preferablyja part of a structure which is foldable, as indicated by Figure 4, so that it may be reduced to compact form and packed in a suitable container with the rack, the latter being of foldable construction, as usual. Said structureincludes a shank 21, secured at its lower end to the midlength portion of the shelf and constituting the preferred means for connecting the shelf with the clamp, and inclined braces connecting the ends of the shelf with the upper end of the shank. The shelf. is transversely divided at 22, into two sections, .each having upturned flanges 23 and 24' at its longitudinal edges. To permit the folding of said structure, theinner flanges 23 are connected by pivots 25 with the lower end of the shank 21, and the braces are composed of lower sections 26, pivoted at 27 to the flanges 23, and upper sections 28, pivoted at 29 to the lower sections, and at 30 to the upper end portion of the shank 21. The said structure may be extended, as shown by broken lines in Figure 4, to locate the shelf sections in alinement with each other, and folded to locate the shelf sections and the brace sections parallel with the shank. The full lines in Figure 4 show the structure only partly folded, it being obvious that the folding may be completed to locate the shelf sections parallel with the shank.

To provide a separable connection between the shank 21 and the clamp ear 17, I provide, in the upper end of the shank, a slot 32, formed to receive the ear 17. When the ear is in the slot and the structure unfolded, extensions 28a of the upper brace sections, enter the ear notches 18, as best shown by Figure 7 and lock the unfolded structure to the clamp. \Vhen the structure is folded, the extensions 28a are withdrawn from the notches, as indicated by broken lines in Figure 7, so that the folded structure is separable from the clamp.

The shank and braces are connected with the inner edge portions of the shelf, and are arranged to laterally support, in one direction, reserve music deposited on the shelf. To laterally support the reserve music in the opposite direction, I secure to the outer edge of the shelf an upwardly projecting resilient tongue 33, which is normall inclined inwardly above the shelf and is adapted to bear yieldingly on the outer side of a collection of reserve music on the shelf and conform automatically to the thickness of said collection, so that either a thin or a relatively thick collection may be clamped and prevented from loose endwise movement between the shank and braces at one side, and the tongue at the opposite side.

\Vhen the structure is adapted to be folded, as described, I connect the tongue by pivots 31 with the outer shelf flanges 24, the pivots 34L being in transverse alinement With the pivots 25 connecting the shelf sections with the shank 21.

The clamp shown by Figures 9 and 10 is also positively engageable with the standard, and is composed of two independent members 36 and 37, formed to embrace the standard 12. The member 36 is permanently riveted or otherwise secured, to the upper end portion of the shank 21. The member 37 is proy ided with an angular slot 38, adapted to receive a headed stud 39, fixed to the shank. A clamping screw 40 is insertible in an orifice 41, in the member 36, and a tapped orifice 42 in the member 37, so that rotation of the screw in one direction clamps the members on the standard, a

reverse rotation releasing the member 37 and permitting its removal from the stud 39, as indicated by Figure 10, so that the shank 21 and the parts supported thereby, are separated from the standard.

The clamp shown by Figures 9 and 10 may be employed when the structure which includes the shank, the shelf, and the braces, is not foldable.

It will be seen that each embodiment of the invention includes a shelf, means for detachably connecting the shelf with a vertically extending music-rack standard and causing the shelf to extend horizontally across the standard, the shelf being provided at its inner edge with upstanding supporting means, such as the shank 21 and the inclined braces, adapted to laterally support the inner side of a collection of reserve music, and at 1ts outer edge with upstandlng supporting means, adapted to support the outer side of said collection, said supporting means forming opposite sides of an endless holding space above the shelf, so that the attachment is adapted to hold music sheets which are longer than the shelf.

It will also be seen that in each embodi ment of the invention the inclined braces and the shank 21 are arranged to cooperate in laterally supporting the inner side of a collection of reserve music on the shelf 20, and the tongue 33 is arranged to laterally support the outer side of said collection. The shank and braces project upward from the inner edge of the shelf and form the. inner side of an endless holding space above the shelf while thetongue projects upward from the outer edge of the shelf and forms the outer side of .said endless holding space.

may project outwardly from the ends thereof.

The compressibility of the standard-embracing clamp and the clamping screw whereby the clamp may be compressed and maintained under compression, permit a positive engagement of the clamp with the standard 12, so that only one clamp is required tomaintain the shank 21 in a Vertical position, and the shelf 20 in a horizontal position.

I claim 1. A reserve music-holding attachment comprising a clamp having means for separable engagement with a music rack standard, and provided with a projecting ear having notches in its opposite sides, a shank having in one end portion a slot formed to receive said ear, a shelf composed of two relatively movable sections pivoted at their inner ends to the opposite end portion of the shank, and inclined braces extending from the outer ends of the shelf sections to the slotted end portion of the shank, and composed of lower sections pivoted to the inner edges of the shelf sections adjacent the outer ends thereof, and upper sections pivoted to the lower sections and to the shank, and provided with extensions arranged to enter the grooves in the clamp ear, and thereby lock the shank to said ear, the shank and braces being arranged to laterally support reserve music deposited on the shelf, the structure including the shelf, the shank and the braces being foldable, to disengage the brace extensions from the clamp ear, and reduce the structure to compact form.

2. A reserve music-holding attachment as specified by claim 1, comprising also a resilient upwardly projecting tongue, pivoted to the inner ends of the shelf sections at the outer edges thereof, and projecting upwardly from the shelf, to laterally support reserve music deposited on the shelf.

In testimony whereof I have affixed my signature.
