May 4, 1937. J. E. KLUsoN MUSIC STAND Filed April 10, 1936 o d M f '.nlmll alllllnml' Patented May 4, 1937 UNITED STATES PATENT ortiesv Application April 10, 1936, Serial No. '73,639V i g claims. v(c1. i5- 121) The present invention relates `generally to stands. More particularly the invention relates to that type of stand which is adapted to be used by musicians to support or holdbook or sheet music and comprises (l) a standard which is provided at its lower end with legs for supporting it in an upright or vertical position and has a bracket pivotally connected to the upper end thereof; and (2) a rack which is detachably connected to, and is supported for vertical angular adjustment by, the bracket at the upper end of the standard and comprises a one-piece horizontally` extending angle bar-type ledge forming bottom member and a pair of laterally spaced collapsible link formed music supporting frames.

One object of the invention is to provide a music stand of this type in which the frames of the rack are so constructed and are pivotally connected to opposite ends of the top flange of the bottom member in such manner that when they are swung into their collapsed position one fits against and is substantially coextensive with the front face of the top web and the other ts against and is substantially coextensive with the back face of said top web of the bottom member andis in lapped relation with respect to the one frame and the rack as a whole is hence eX- tremely compact and occupies but a minimum space when the frames are in their collapsed position.

Another object of the invention is to provide a music stand of the type under consideration in which the braket for supporting or carrying the rack so that it may be swung or adjusted vertically into different positions comprises a rec-l tangular plate which underlies the central portions of the inner side links of the collapsible frames and the detachable connection between the rack and the bracket is in the form of upwardly extending outstruck tongues on the side margins of the plate and tongue receiving slots in the inner side links of the frames.

A further object of the invention is to provide a music stand of the type and character last mentioned in which the central portion of the tongue-equipped plate of the bracket is raised with respect to the side margins and forms a spacing member which tsbetween, and abuts against the inneredges of, the inner side links of the frames and servesrto prevent the frames from swinging or tilting sidewise out of their normal position when the rack is in connected relation with the bracket.` i

A still further object of the invention is to provide a music stand Which consists of but a small number of parts, may be manufactured at alowand reasonable cost, and -ls generally an Vimprovement upon and simpler in construction than previously designed stands of the same general type. f

Other objects of the invention and the various advantages and'characteristics of the present music stand will be `apparent from a considerae tion of the followingV detailed description.

In the drawing which accompanies and forms a part of this specification or disclosure and in which like numerals of reference denote corresponding parts throughout the several views:

Figure l is a perspective of the music stand embodying the invention; Y

Figure 2 is a front view showing the rack detached from the bracket at the upper end of the standard and the frames in partially collapsed position;

Figure 3 is an enlarged section taken on the line 3 3 of Figure 1 and showing in detail the construction and design of the tongues and slots which form the detachable connection between the rack and the bracket; and

Figure 4 is an enlarged section taken on the line 4--4 of Figure l and illustrating in detail the cross-sectional construction ofthe plate of the bracket and the manner in which the central raised portion thereof lits between the inner side links of the frames and serves to hold the frames against relative tilting or swinging movement when the rack is in its fully extended or normal position and in connected relation with the bracket.

The stand which is shown in the drawing constitutes or represents the preferred embodiment of the invention and is adapted primarily for use by musicians in that it is designed to support in an elevated and substantially vertical position book or sheet music. It is formed of metallic parts and consists of a standard 5, a

bracket 6 at the upper end of the standard, and a music supporting rack 'l on the bracket. The standard 5 is adapted to be supported or held in a vertical or upstanding position by means of legs (not shown) at the lower end thereof. The bracket 6 is pivotally connected to the upper end of the standard,v as hereinafter described, and serves to support the rack 'l so that it may be tilted or swung vertically into diiierent positions.

The rack I consists of a horizontally extending angle bar type bottom member 9 and a pair of laterally spaced or positioned rectangular linkformed frames S and i0. The bottom member 8 forms a ledge on which the rack supported music is adapted to rest and consists of a top web II and a bottom web I2. The web II is formed integrally with and extends at right angles to the bottom web I2. The frame 9 is associated with one end of the bottom member 8 and comprises an outer side link I3, an inner side link I4, and a cross-link I5. The side links I3 and I4 are arranged in parallel relation and extend upwards and at right angles with respect to the bottom member 8 when the frame 9 is in its extended or normal position. The lower end of the outer side link I3 ts against the back face of said one end of the top web I I of the bottom member 8 and is connected pivotally to the top web by means of a rivet I6. The inner side link I4 is the same in length as the outer side link I3 and the lower end of the inner side link I4 fits against the back face of the central portion of the top web II and is pivotally connected to the web by a rivet I'I. The cross-link I5 extends parallel to the bottom member 8 of the rack and extends between and is pivotally connected by rivets I8, I8a to the upper or distal ends of the side links I3 and I4. By reason of the fact that the links I3, I4 and I5 of the frame 9 are connected pivotally, as hereinbefore described, the frame is adapted to be swung toward the opposite end of the bottom member 8 into a collapsed position wherein the links thereof are in longitudinal alignment and t against or lap the back face of the top web II of the bottom member 8. The combined length of the outer side link I3 and the cross-link I5 is substantially equal to the length of the bottom member 8 and therefore the frame 9, when in its collapsed position is no longer than and does not project beyond the bottom member 8. The frame 9 in addition to the side links I3 and I4 and the cross-link I5 comprises a pair of links I9 and 20, and a pair of links 2| and 22. The link I9 underlies and extends parallel to the cross-link I5 and the link 20 is positioned inwardly of, and is parallel with, the outer side link I3. The outer end of the link I9 is pivotally connected by a rivet 23 to the central portion of the outer side link I3 and the other or inner end of the link i9 is pivotally connected by a rivet 24 to the lower end of the link 20. The upper end of the last mentioned link lits against the front face of the crosslink I5 and is pivotally connected by a rivet 25 to the central portion of the cross-link. The links I9 and 20 assist the side links I3 and I4 and the cross-link I5 in forming a backing or support for the rack supported music and are positioned or disposed in longitudinal alignment and in lapped relation with respect to the back face of the top web II of the bottom member 8 when the frame 9 is in its collapsed position. The links 2I and 22 also assist the side links I3 and I4 and cross-link I5 in forming a backing for the rack supported music and are adapted when the frame 9 is in its collapsed position to lap the back face of the top web II of the bottom member 8. The link 2I is disposed beneath and extends parallel to the cross-link I5 and the central portion thereof is pivotally connected by way of a rivet 26 to the central portion of the outer side link I3. As shown in Figure l of the drawing, the link ZI is positioned or located at a point one-third oi the distance from the rivet i8 to the rivet I6 and the link I9 is positioned midway between the link 2I and the rivet I6. The central portion of the link 22 ts against the back face of the cross-link by a rivet 2l which is located at a point one-third of the distance from the rivet I8 to the rivet |89. The lower end of the link 22 is pivotally connected to the inner end cl' the link 2l by a rivet 28. The outer ends of the links 2l and 22 project respectively beyond the outer side link I3 and the cross-link I5 when the rack 9 is in its normal or extended position, as shown in Figure 1, serve to support sheet music which is large in size. The link 20 is located midway between the link 22 and the inner side link I4. The rivets I8, 28, 24 and Il are in alignment, that is they are disposed in the same plane and hence the frame 9 collapses freely.

The frame I9 of the rack 'I is associated with the opposite or other end of the bottom member 8 and comprises an cuter side link 29, an inner side link 30, and a cross-link 3l. The

links

29 and 39 are spaced apart the same distance as, and are equal in length to, the links I3 and I4 oi the frame 9 and extend upwardly and at right angles with respect to the bottom member 8 of the rack v'I when the frame is in its extended or normal position. The lower end of the outer side link 29' fits against the front face of the top web Il of the bottom member 9 and is pivotally connected to said-other or opposite end of the top web by means of a rivet 32. The lower end of the inner side link 39 is spaced a small distance from the inner side link I4 of the frame 9, as shown in Figure l. It fits against the top web I I of the bottom member 8 and is pivotally connected to the top web by means of a rivet 33. The crosslink 3l is the same in length as the cross-link I5 and extends between and is pivotally connected by rivets 34 to the upper or distal ends of the

side links

29 and 39. As a result of the arrangement of the

side links

29 and 30 and the cross-link 3|, and the manner in which these links are pivotally connected, the frame I9 may be swung towards the frame 9 into a collapsed position. When the frame is in its collapsed position the side links 29 and 3D and the cross-link 3l fit against the front face of the top web II of the cross-member 8 and are in lapped relation with respect to the links of the frame 9. In addition to the

side links

29 and 30 and the cross-link 3l, the frame I9 comprises a pair of

links

35 and 36 and a pair of links 3l and 39. The

links

35 and 38 correspond to the links I9 and 29 and are pivotally connected to the outer side link 29 and the cross-link 3i in the same manner as the links I9 and 29 are pivotally connected to the outside link and cross-link of the frame 9. The links 3l and 38 correspond to the links 2| and 22 of the frame 9 and are arranged in similar relation. The combined length of the outer side link 29 and the cross-link 3| is slightly less than the length of the bottom member 3 ol the rack 'I and as a result the frame I9, when in its collapsed position, does not project beyond the ends of the bottom member 8. By reason of the fact that the side links of the frame Ill lit against the front face of the top web II of the bottom member 3 and the side links of the frame 9 t against the back face of the top web the frame Il! is forwardly positioned with respect to the frame 9 and neither frame interferes with the other when the rack l' is collapsed.

The bracket 9 at the upper end of the standard 5 consists of a pair of side plates 39 and a tcp plate 49. The side plates are substantially semicircular and are positioned in laterally spaced relation and on opposite sides of the extreme upper end of the standard 5. As shown in Figures 3 and 4 the standard is formed of rod type stock and the upper end thereof is flattened so that the side plates 39 of the bracket 6 fit flatly thereagainst. A rivet or stud 4I extends through the side plates and the attened upper end of the stand and connects the bracket to the standard so that it, together with the rack 1, may be swung or adjusted vertically into different angular positions. 'I'he straight portions ofthe side plates are bent outwards or sidewards in opposite directions in order to form ears 42. in iits against these ears, as shown in Figure 4, and is xedly secured to the ears by means of rivets 43.` The bracket 6 is releasably locked in its various adjusted or tilted positions by means of a bolt 44 and a'wing-nut 45. The bolt is located beneath the stud 4| and comprises an externally threaded shank 46 and a head 4l. The shank extends througha hole l48 in the attened upper end of the standard 5 and arcuate slots 49 in the side plates `39 of the bracket 6. The

head 4l of the bolt ts against one of the sidev plates and the wing nut 40 is mounted on the threaded portion of the shank of the bolt and when tightened operates to clamp the side plates to the flattened upper end of the standard. The central portions of the inner side links I4 and i it `of the collapsible frames are adapted to rest on the side margins of the top plate 40 of the bracket 6 and the rack is connected to the bracket by means of upwardly extending tongues 50 on the top plate of the bracket and slots` 5| in the central portions of the inner side links. The tongues 5B are formed integrally with, and struck outwards from the side margins of the top plate of the bracket and are adapted to extend through the slots 5| and form hooks f or supporting the rack. Preferably there are two tongues on each side margin of the top plate and these tongues, as shown in Figure 2, are positioned one above the other.v 'Ihe slots 5| extend longitudinally or lengthwise of the inner side links of the frames 4o and have enlarged lower ends to permit of ready tilting of the frames. The central portion of the top plate 40 of the bracket is raised with respect to the side margins and forms a spacing member which flts between and abuts against the inner l side edges of the inner side links of the frames Cil and serves to prevent the frames from swinging or tilting sidewise out of their normal position when the rack is in connected relation with the bracket. Preferably the central portion of the top head of the bracket is raised to such an extent that the top or front face thereof is flush with the upper faces of the links I4 and 30, as shown in Figure 1. As a result of raising the central portion of the top plate and forming the spacing member between the inner side links of the collapsible lframes 9 and l0 a recess 52 is formed in the bottom of the plate. The ears 42 on the side plates 39 of the bracket fit within this recess, as shown in Figure 4.

When it is desired to dismantle the stand the y rack 1 is disconnected from the bracket 6 by sliding or moving it upwards in order to disengage the tongues 50. After release of the rack the frames 9 and l0 are collapsed by swinging Athem towards one another into a position where- Thecentral portion of the top plate the stand the frames 9 and I0 are swung upwards into their extended or normal position (see Figure 1) and the rack is then applied or connected to the bracket by inserting the tongues 50 through the slots 5| and into hooked relation with respect to the inner side links of the frame. When the rack isin connected relation with the bracket Vtheraised central portion of the top plate of the bracket iits against the` inner edges of the inner side links of the frames and prevents the frames from swinging or tilting sidewise ofl their normal position as heretofore pointed out. In

`order angularly to adjust the rack when the rlatter is connected to the bracket, it is only nec-` essary to loosen the wing-nut 45 vand then swing the rack together with the bracket into any desired position.

V The herein described music stand consists of but a small number of parts and hence may be manufactured at a low and reasonable cost. Due to the construction and arrangement of the collapsible frames the rack when disconnected from the bracket and collapsed occupies but a small space and may be conveniently carried or transported from place to place.

The invention is not to be understood as restricted to the details set forth, since these may be modied within the scope of the appended claims, without departing from the spirit and scope of the invention.
