PORTABLE MUSIC STAND 2 Sheets-Sheet 2 Filed May 1, 1936 Patented May 2, 1939 UNITED STATES PATENT OFFICE 6 Claims.
This invention relates in general to a portable music stand and more particularly to a music stand which may be disassembled and folded up in the form of a small valise, which also may be 5 used to carry music and the like.
Musicians who travel from engagement to engagement, and are playing for dances and concerts and the like, must carry with them in addition to their instruments and their music some 10 form of supporting device upon which they can spread the sheets of music from which they are to play. In playing at such engagements it is necessary that the music stand be a very rigid and durable one. Particularly in dance engagei5 ments it is common practice to place a large number of different sheets of music on the stand so that the various selected pieces of music in the program may be always at hand and quickly available. It is also necessary that music stands 2 of this character be compact and readily portable when disassembled. Portable music stands which have been previously in use are very light weight in construction and tend to be extremely topheavy when in use, with the result that a great 25 deal of trouble has been experienced due to collapse and overturning of the music stands.
It is an object, therefore, of the present invention to provide a compact readily portable music stand which will be strong and durable when 30 assembled for use. It is also an object of the present invention to provide a music stand which may be utilized in part as a carrying case for the musicians accessories, such as his sheet music, when the stand is disassembled. It is an 35 additional object of this invention to provide a portable music stand which will be commodious and capable of supporting large quantities of sheet music when the stand is in assembled position. It is furthermore an object of this inven- 40 tion to provide a stand which is very quickly and simply assembled and disassembled and does not tend to become top-heavy when used. It is another object of the present invention to provide a portable music stand which is attractive in ap- 45 pearance when assembled and ready for use.
Other objects and advantages of the present invention will more fully appear from the following detailed description, which, taken in connection with the accompanying drawings, will disclose to those skilled in the art the construction and operation of a preferred form of the present invention.

The embodiment shown in Fig. 1 comprises a box-like satchel or valise I, which is provided with a suitable handle 2 and is formed in two hollow box-like halves 3 and 4, respectively, which hingedly fit together along the center line 5. Along one end of the face 6 of the portion 3 is a closely fitting flap member I which fits tightly in the side of the valise when the same is closed. A similar flap member 8 is located in the other half 1 of the device. The valise is adapted to be opened out flat as shown in Fig. 2, and the flaps! and 8 folded down to form shelves therefor, the two halves of the valise forming the two wings of the music stand. The standard ID as shown in more detail in Figs. 2, 8, and 10, comprises a plurality of interfitting parts, each part being of such size that when disassembled they may be conveniently placed inside of one of the box-like halves of the satchel as shown in Fig. 8. This standard H3 is assembled from its parts and attached to the box-like portion of the valise, as shown in Fig. 3, in such a manner that the valise or case will be rigidly held in extended position to form the rack or head member of the music stand.
The standard comprises a heavy triangular base portion H, into which a plurality of feet [2 are removably inserted. The base H has a centrally located, internally threaded hole I3 into which an upright section l4 may be threaded at one of its ends. The other end of the upright portion is adapted to receive a second upright The second upright member I5 isportion 15. preferably provided with an adjustment member I5. A rod-like third upright portion I1 is adapted to slidingly fit into the adjustment member I6, whereby the height of the stand from the floor may be varied. The third upright member I1 is provided at its upper end with a swivel head [8, which is adapted to clampingly engage the boxlike portion of the music stand.
These parts of the standard It], as has been above pointed out, are disassemblable and are adapted to fit into the very small compass of the one side of the box-like portion of the music stand. This box-like portion may be provided with a suitable inside leaf cover 20 which may be hinged down over the opening of this half of the box-like case I. The other half of the carrying case I may be utilized to carry the sheets of music which every musician takes with him to his various engagements. This other compartment may also be provided with a similar inside leaf cover member 2|.
When it is desired to set up the music stand the carrying case is opened, the inside leaf cover 2% is folded back and the parts of the standard are removed and fitted together. The leaf 2! is then folded back and the music removed. The handle of the carrying case is capable of being folded inside the carrying case out of sight, as will be later explained. The leaf covers 29 and 2| may be then secured in place by suitable catches provided thereon.
The leaf covers 29 and 2| provide the surface which is visible to the audience as the back of the music stand when the same is in operative position. Therefore, it may be desirable to ornament these surfaces with a suitable design or scroll work. In order that the clamp for attaching the box-like portion to the swivel head may grip the suitable side wall members of the box, rectangular holes 22 and 23 are provided in the cover members 29 and 2|.
The collapsible handle, as shown in more detail in Figs. 9, l1, and 12, comprises a suitable leather grip member 25 which is attached at its two ends respectively to the metal loops 26 and 27, respectively. The handle is provided with a base plate 28, on the rear edge of which is mounted a hinge 30. The stationary leaf of the hinge is mounted rigidly to the top inside of the carrying case. The closure edge of the carrying case is of course provided with slight recesses to allow the metal loops 26 and 2! to pass upwardly therethrough. The loops 26 and 21, respectively, pass through the slots 3! and 32 in the base plate 28 and are rigidly mounted on the catch members 33 and 34, respectively. The catch members 33 and 34, respectively, are hingedly mounted on the bottom of the base plate at 34 and 35, respectively, and are adapted to swing through a small arc due to a certain amount of play between the slots and the metal loops. The base plate is provided with spring members 31 and 38, respectively, which engage the catch members and urge them respectively toward each other. The other side of the container is provided with suitable detent means 40 and ll, into which the catches may fit. When the carrying case is closed the catches fit into the detent means and hold it in closed position. When it is desired to open the case the metal loop members 3| and 32, respectively, may be urged away from each other. This is possible because of a considerable amount of flexibility in the leather handle. This causes the catch members 33 and 34 to be rotated away from operative engagement with the detent means and they may therefore be withdrawn from the detent means and the case opened.
As the case is opened and the catch members are released from the detent means, the handle is no longer held in upright position since it is obvious that the hinged base plate of the handle will normally rotate downwardly away from the plane of the top of the carrying case unless restrained by engagement of the catch members in the detent means. Thus when the case is opened the whole handle catch assembly will be rotated with the base plate about the hinge 33, down into the interior of the box and may be concealed therein until it is necessary to use the handle catch means again in closing the case and transporting the same.
The outside faces of the box-like case or valise are also provided with two flap members 1 and 8,.respectively, as above mentioned. The operation of the flap members is more specifically shown in cross section in Fig. 10. The flap member 8 comprises a shelf member 4!]. This memher is made of fairly thick, substantial material so that it is capable of supporting a consid erable weight without bending or yielding. In the forward edge thereof is a small longitudinal hole ll, which is adapted to receive the keeper member 42 on the catch 43 when the flap is in folded up position. This detent and catch means is adapted to hold the flap member in closed position so that it will fit tightly into the side of the valise and form an integral part thereof. At the rear end of the shelf member 40 is a back stop member M. This back stop member 43 extends perpendicularly away from the shelf member 40 so that the entire flap member 8. assumes an L-shaped cross section. When the flap is in folded up position the back stop member 44 lies inside the box, as shown in dotted lines. The flap member is mounted in the valise by a hinge member 65. The flap member, when it is rotated about the hinge 45, moves outwardly and the heel portion 38 of the shelf member 40 swings down into abutting relationship with the forward edge of the bottom 81 of the valise.
By reference to Fig. 2 it will be seen that some variation in the alignment of the parts might cause the two shelf members i and 8 to lie in slightly different planes. This would be undesirable. Therefore an adjustment screw 48 is provided for each of the flaps. It will be seen that as this screw is threaded in and out of the bottom member 41 it will tend to cause the heel portion 41 of the shelf 40 to come into abutting relationship with the head at slightly different positions with respect to rotation around the hinge '45. By adjusting the two adjustment screws, the flaps 1 and 8 may be brought into perfect alignment.
The valise, after it is in opened-up position and the stand has been set up, must be rigidly mounted on the stand, as has been above pointed out, in a manner so that it will form a rack'or head portion of the music stand. This is accomplished by the clamp and swivel head assembly shown in detail in'Figs. 10 and 13.- A pair of clamp guides 50 and 5| are rigidly mounted on the inside side walls 52 and 53 of the valise. The valise of course is hinged about a plurality of hinges 54. Thus the side walls 52 and 53 come into abutting relationship when the valise is opened out fiat. Thus the two clamp guides 55 and 5| fall into the position relative to each other as shown in Fig. 13. A detent depression 55 is provided in the clamp guide 50. A suitable U- shaped clamped member 56 is provided. The clamp member 56 is just wide enough to encompass the thickness between the engagement surfaces of the two clamp guides 50 and 5|, and is of sufiicient width to slide into it between the guideways of the clamp guides. This clamp member is also provided with a retention screw 51, which is so located on the clamp that when the clamp is fully in place in the clamp guides, the
retaining screw may be screwed forward in the clamp to engage the detent depression 55. The heel portion of the clamp 58 is provided with a centrally disposed hole 60 through which a suitablepivot pin 6| may pass. The back surface of the heel member 58 is provided with a plurality of gear teeth 52. The heel member is adapted to fit rotatingly within the swivel head l8, as shown in Fig. 10. The swivel head is also provided with an elevator screw 63, which passes through the swivel head and has a centrally located worm screw 54, which engages the gear teeth 62 on the heel member of the clamp. Rotation of the elevator screw 63 causes the clamp member to rotate in the swivel head about the pin 6|. This rotation of the clamp member causes the opened-out valise, or head portion of the music stand, to rotate, whereby the angle of the music stand with respect to the floor may be varied to suit the requirements of the individual musician. I
It is similarly desirable, as has been above pointed out, to vary the height of the rack or head portion from the floor to accommodate the needs of the individual musician. For this. purpose, as has been above pointed out, the rod member I! is slidable within the section l5 of the standam. A suitable clamp member lfi'is provided at the top of the section I5 of the standard. ThlS clamp member comprises a circular sleeve 65 adapted to encircle the rod 11. A clamp screw 68 passes through the portion of the sleeve 65 which is threaded to receive it. The inside portion of the clamp in the proximity of the threaded portion is provided with a recess 61. The head of the clamp screw 66 has an enlarged portion 68 which is adapted to fit into the recess. This prevents the clamp screw from being crowded back out of the sleeve entirely and becoming lost. A clamp shoe [0 is disposed inside the sleeve 65. This shoe preferably has an arcuate cross section so as toclampingly fit the rod I! more accurately. This clamp shoe H1 is impelled forward by the enlarged portion 68 on the clamp screw as the clamp screw is threaded up into the sleeve member 65. In order that the clamp shoe may not be lost out of the sleeve when the stand is disassembled, an extension member H is provided on the bottom thereof. This extension member is adapted to slide freely in a suitable hole provided in the sleeve. A small screw 12 is adapted to fit into the extension N. This screw 12 is provided with a head which is substantially larger than the hole through which the extension passes. Thus the clamp shoe I0 is free to move toward and away from the rod H within the sleeve and yet cannot fall completely out of the sleeve and become lost.
Another embodiment of the invention is shown in Figs. 4 to 7, inclusive. In this embodiment the stand 'and swivel head are substantially the same,
viously described. This is also provided with a handle 8! which is substantially similar to the handle 2 described above. The handle 2 is likewise adapted to fold into the interior of the valise when the same is in opened-up position. Each half of the valise, however, is provided with two holes 82 and 83 as shown in Fig. 4. These holes are adapted to receive the means 84 by which the swivel head of the stand is adapted to the valise in order to form a head for the music stand.
The valise contains interior hollow halves as described in connection with the previous embodiment, in which the parts of the stand may be kept, and also in which music or accessories may be kept. When the valise is opened as shown in Fig. 5 the interior hollow halves are provided with leaf covers 85 and 86, respectively. These leaf covers are similar to the leaf covers 20 and 2| described in connection with the previous embodiment. However, they are somewhat shorter than the length of the interior compartment. A fiat shelf member 81 is hingedly mounted in the bottom of each half as shown in Fig. 6. Thus when the stand is in set-up position the leaf covcm are raised up and the shelf members 81 folded down. The cover 86 is then returned over the opening to form the back rest of the music stand and also serve to hold the shelf member 8'! in opened-down position. The swivel head in this embodiment, as shown in Fig. 7, is provided with a heel portion 90 which is substantially similar to the heel portion 58, as described in connection with previous embodiment, and has the same ear-toothed rear end portion adapted to engage the elevator screw. The forward portion of this swivel head member, however, consists of a base plate 9! on which are mounted two pins 92 and 93, respectively, and two mounting screws 94 and 95, respectively. The pins fit into suitable hole members 82 in the back of the valise. The screw members fit into threaded sleeves 83 mounted in the back of the valise. Thus the back of the valise may be securely mounted against the base plate 9| and afiixed to the standard of the music stand.
It is thought that the invention and numerous of its attendant advantages will be understood from the foregoing description and it is obvious that numerous changes may be made in the form, construction and arrangement of the several parts without departing from the spirit or scope of the invention, or sacrificing any of its attendant advantages, the forms herein described being preferred embodiments for the purpose of illustrating the invention.
