MUSIC STAND AND RACK.

SPECIFICATION forming part of Letters Patent No. 430,240, dated June 17, 1890. Application filed September 3, 1839- Serial No. 322,850. (No model.)

To all whom it may concern:

Be it known that I, CLAYTON S. STEVENS, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Music Stands and ftacks, of which the following is a specifica- My invention relates to improvements in music stands and racks of the class that fold and are sometimes designated as knockdown stands and racks; and the objects of my invention are simplicity of construction and gen eral efficiency, and particularly to conveniently fold the same into a compact form.

In the accompanying drawings, Figure 1 is a side elevation of my music-stand as detached from the rack and folded. Fig. 2 is a side elevation of the same as set up ready for use. Fig. 3 is a detached view of a portion of the rack in a partially-folded position. Fig. 4 is a front elevation of the rack placed in position upon the upper end of the standard. Fig. 5 is a View of said rack in a partlyfolded condition. Fig. 6 is a like view of the same still farther folded. Fig. 7 is a side elevation of the rack completely folded, the lower member being sectioned upon one side, so as to better show the other parts. Fig. 8 is a plan view of the central portion of the rack, together with the stud upon the standard, by which it is secured in place. Fig. 9 is a section of the same on the line 00 0c of Fig. 8. Fig. 10 is a horizontal section of the standard on line y y of Fig. 2, showing the legs in plan view. Fig. 11 is a transverse section of one of the legs. Fig. 12 is a side elevation of the standard and some of the connected parts, illustrating the manner of folding the legs. Fig. 13 is a like View of the same parts in another position. Fig. 14: is a side elevation of the lower end of the standard, a part of one leg, and braces, illustrating a modification; and Fig. 15 is a horizontal section thereof on the line 2 z.

A designates a standard, which is made hollow and provided with a telescopic section B, and a central section or rod 0, which is held in its adjusted position by means of the set-screw 1 6, all substantially as in well-known extensible standards of prior make. The extreme upper end of .the central rod is proupper and

lower sections

20 and 21, hinged together bya stop-joint, as at 22. Forthe purposes of strength and facilitating constructing the joint,I form these legs of angle-iron or flanged iron, as shownby the cross-section, Fig. 11, and in jointing the upper and lower sections together this flange is arranged at the upper or outer edge of the legs, but facing in opposite directions, as shown most clearly in Figs. 2, 12, and 13. At the lower end of the standard I rigidly secure a winged hub 23, by which to secure one end of the lower braces 24, the other ends of which braces are pivoted to the lower sections 21 of the legs at 25. I also arrange upon the standard A devices for holding the legs down, consisting of a sliding winged collar 26 and the upper set of braces 27, the lower ends of said braces being pivoted to the upper sections 20 of the legs and their upper ends being pivoted to said sliding winged collar. The sliding collar 26 is provided with a set-screw 28 for fastening it in position upon the standard when the standard is set up. The position of the braces, legs, and standard is shown in Fig. 2, when they are in position for use, in which case the set-screw 28 is tightened to lock the upper braces, and thereby firmly hold the tripod in its extended position. This combination of legs, braces, and standard gives a firm and substantial tripod or stand, which isof very light weight, and which will readily fold-into a compact form. By loosening the set-screw 28 and swinging the braces and upper members of the legs outwardly and upwardly the collar 26 will slide upwardly on the standard and the lower section of the legs will swing inwardly into a position parallel to the standard, Fig. 12 illustrating one leg and its braces as being moved into this position. A continuation of the same movements brings the parts into the position shown in Fig. 13, and finally into the position shown in Fig. 1.

In Figs. 14: and 15 I have illustrated a modification, by which the legs may be separately adjusted for standing upon an uneven sup- IOO port, as, for instance, the ground. In the construction first described the legs all move together, and are therefore adapted for use upon a level surface only. In the modification I propose that the winged collar 29, to which the legs are secured, and which takes the place of the collar 19, shall be provided with a set-screw 30, whereby said collar may be raised and lowered upon the standard and fastened in place to spread the legs to a greater or less extent. I also give the wings of the collar and hub 26 and 23 a greater vertical height,,so that they may be slotted vertically, and I secure the braces thereto by means of a bolt 31 and thumb-nut 32, the body and threaded portion of said bolt being flattened and extending through the slots in the wings. This will permit the inner ends of thebraces 24: and 27 to be adjusted to different heights, whereby the legs may be individually adjusted, so as to spread them to a differentextent, and thereby level the stand when the legs are resting upon an uneven surface. In both forms of stand the winged collar, winged hub, legs, and lower braces govern the folding movement of the legs as well as strengthening the stand, while the upper set of braces, sliding collar, and setscrew are in the nature of devices for holding down the legs.

In the rack there is a central bar or body 33, provided with a key-hole-shaped opening 34 to receive the headed pin 18 and steadypin 17 for holding the rack upon the central rod of the standard, shown in Figs. 4:, 8, and 9, the same being a well-known construction for attaching two articles together, and for which any other known devices may be substituted. To this central bar or body 33, I pivot at the lower end, on each side, the flanged bases 35, and at the middle portion of said bar or body I pivot the parallel bars 36, and at the upper end of said bar or body the shorter bars 37. To the outer ends of these shorter bars 37, I pivot extension-bars 38, which, when in the position shown in Fig. 4, form a continuation or extension of the bars 37. To the outer ends of the bases 35 and parallel bars 36, I pivot the longer section 39 of the side bars that form the ends of the rack, the upper ends of these longer sections being offset at 40. The shorter section 41 of the side bars is pivoted to the upper ends of the longer sections and to the outer ends of the extension-bars 38, so that when the bars are unfolded they form a'rectangular rack, as shown in Fig. 4. parallel bar 36 is pivoted to the longer section 39 at a point below its upper end, and the lower end of the shorter section 41 is pivoted to the upper end of said longer section, whereby the pivot or joint of said

section

39 and 41 is not common to the joint at the outer end of the parallel bar 36 and said section 39. The bases 35 and parallel bars 36 are pivoted to the under side of the bar or The outer end of each body 33,'while the shorter bars 37 are pivoted to the upper side thereof. All of these swinging bars have their downward motion limited by means of the stop-lugs 42 on the bar or body 33 adjacent to the several joints, thereby forming what may be termed stophinges for all the parts that are hinged or pivoted to said bar or body 33.

In order to fold the rack, the bases and connected bars may be swung upwardly into the position illustrated in Fig. 3 until the bases 35 and bars 36 and 37 shut or fold one back of the other, after which the

bars

41 and 38 may be turned outwardly and then inwardly between the

bars

37 and 36, as shown in Fig. 7, thereby completely folding the rack. If desired, the parts may be folded by first throwing up the bar 37 until the

bars

38 and 41 are in alignment, as shown at the right-hand corner of Fig. 5. Then force inwardly the connected ends of said bars to the position shown at the left-hand corner of said Fig. 5, after which the bases and attached bars may be swung upwardly, as shown in Fig. 6, and finally folded completely together, as shown in Fig. 7.

By forming the side and top bars of the rack with the

parts

41 and 38 at each upper corner pivoted to each other and to the connected bars I am enabled to fold said

parts

41 and 38 back, as described, whereby the folded rack is of less length than it would otherwise be.

I am aware that a prior patent shows a folding music -rack and folding tripod or stand, and that the latter has a standard, jointed legs, braces, and a sliding collar that moves over that portion of the standard which is below the point where the legs are pivoted to said standard, and the same is hereby disclaim ed.

I claim as my invention 1. The combination of the standard A, the winged collar 19, fixedly secured on said standard near its lower end, the legs composed of two members pivoted together with the upper section pivoted to said collar, the winged hub 23, fixedly secured to the lower end of the standard below the collar 19, and the braces 24, pivoted to said hub and lower members of the legs and the upper braces and sliding collar, substantially as described, and for the purpose specified.

2. The combination of the standard A, the winged collar on said standard near its lower end, the legs composed of two members pivoted together with the upper section pivoted to said collar, the winged hub 23, secured to the lower end of the standard below the collar 19, the braces 24, pivoted to said hub and lower members of the legs, the sliding collar 26, its set-screw 29, and braces 27, pivoted to said collar and upper section of the legs, substantially as described, and for the purpose specified.

3. The combination of the bar or body 33,

bases 35, parallel bars 36, shorter bars 37, said bases and bars all pivotally connected by their inner ends to said body, the shorter bars 38, pivotally connected to the outer ends of the shorter bars 37, and the side bars composed of the longer section 39, offset at their upper ends, and shorter SGC'ElOIt-ll, said bases 35 being pivotally connected by their outer ends to the lower ends of said longer section 39, said parallel bars 36 being pivotally connected to said longer section 39 at points below the offset at their upper ends, while the shorter sections 41 are pivot-ally connected by their lower ends at points above said offset and above the pivotal connection of36 and 39 to the longer sections 39, and by their upper ends to the outer ends of the shorter Witnesses:
