STAND.

Application filed June 25, 1924.

To all @071 am it may concern.-

of use for holding drums, saxo-phones, and l other musical instruments.

The principal objects of the invention are to provide an improved sliding oint for the adjustment of the central vertical upright of the stand; to provide an improved detachable pivotal connection for the mus1c rack or the like at the top of the central up.

rightstandard; to provide an attachment for the music rack by which it will be adapted to hold down securely the edges of music longer than the rack is wide or shorter; and to provide a convenient locking device adapted to come into position automatically by gravity for locking the pivoted legs at the desired angle with respect to the bottom of thestanda-rd. These various features are capable of conjoint use and tend to im prove such a stand in such a way as to permit all the parts tobe folded up into very small compass in spite of the additional features which .I have shown herein. Other features and advantages of the invention will appear hereinafter.

Reference is to be had to. the ing drawings, in. which Fig. .1 is a front elevation of a music stand constructed in accordance with this invention and shown in position for use and also showing in dotted lines'how the legs are folded up;

Fig. 2 is a side elevation of the same;

Fig. 3 is a central vertical sectional view on enlarged and approximately full sized scale of'the sliding joint for the vertical stand accompany- Fig. 4 is a rear elevation of the same with parts broken away to show interior construction;

Fig. 5 is a sectional view on the line 5-5 of Fig. 3 on further enlarged scale; and

6 is a fragmentary side elevation of the looking gravity catch.

I have shown the invention in the drawings as applied to a stand for holding music in sheet, aamphlet or book form although it is capa le of other uses as will appear.

Serial No. 722,386.

Folding stands for this purpose have reached a high: stage of development and they are.

The upright standard in the form shown,

consists of three members, a hollow tube 10, uniform through its length, a second tube 25,

and an upper rod or tube 26. At its lower end the lower tube 10 is provided with a bracket 11 preferably of sheet metal and having three equally spaced tangential pivot pins 12 each extending across a space be tween two integral arms '13 and each located horizontally. On each of these pins is pivoted one of the three legs 14. These three legs are formed of bar stock and together they are strong enough to support the whole instrument. Each one has pivoted to it a link 15. These links are all located on the same side of each leg and extend upwardly to be pivoted to three integral arms 16 projecting from a tubular slide 17 on the tube 10.

j The slide 17 is formed of sheet metal and the three, arms are formed by punching through the metal around three sides of an area and forcing the arms out to a radial position. This slide is formed from a flat piece of sheet metal, the edges being brought together. to form a complete circle, but not necessarily united with each other. At these edges there are two other arms 18, formed as projections onthe edges of the piece of sheet metal, and bent outwardly so as to be parallel with each other and be spaced apart a short distance. They are connected bya pin on which is pivoted a gravity locking latch 19 having an up-turned hook at the bottom.

. The folded scribed is shown in dotted lines in Fig. 1. In order to expand the device and place it in position for use, the slide 17 is slid down the upright until the upwardly slanting lower edge 20 of the gravity. hook 19 engages a fixed pin 21 on a collar 22 secured in fixed and the legs at spread as far down as they and movingpin 21. Gray position of the parts just dewardly toward the tube 10 and so does the top of the lower end of the hook. Now if a weight is applied, or if the operator pushes down on the rod 10, it will sink a little until the pin 21 comes down into the trough of the hook 20. The parts are thus locked by that hook in that position because the rod 10 cannot be moved down any farther and any further weight merely tends to hold these parts more firmly in position.

Now when it is desired to unfold it this cannot be done by forcing the legs together,

but if the legs are forced apart by vdirect action or by moving the rod 10 down so that the pin 21 no longer bears on the low point of the inside of the hook 19 the device is unlocked and the hook can be swung outwardly by the linger. Ordinarily the operator will tip the whole thing to one side and allow the hook to drop away by gravity and then the legs can be swung backwardly to the dotted line position in Fig. 1. In this folded position the legs ll all swing inwardly at the sides of the links15 and into contact with them. There is no interference of theseparts so the legs can be folded up into contact with the top of the rod 10 and thus this part of the device can be folded into very small compass.

Now referring especiallyto Figs-3, i and 5, although the parts appear also on the other figures, this tube 10 asstated, is open at the top for the reception of the upright tube 25. The whole standard can be formed of two parts only, but I have shown it as composed of three. The third upright 26 is shown as the top one and telescopes into the second one.

except the same way.

Each one is provided with three parallel vertical slits '27 equally spaced around its wall near the bottom. Located inside are three fiat springs 28 bowed outwardly to project out through the three slits. The

upper ends of these springs are secured to p passing freely through a sliding plug 32 at r they project tnroughthe slots with more orless the bottom. The springs are secured at their ends to the two plugs 29 and 32. The screw can be turned out and in to adjust the convexity of the three springs 28 where l and force them force against the inner surface of the larger tube below, as for example, the larger tube in Figs. and l.

In this way ith vill be seen that the head of the screw '30 is located just at the bottom of the member on which it is mounted where it is readily accessible that it can be ad usted-so-that the parts will This can be a solid rod at the bottom,-but both of these parts. 25 and 26 are constructed at the bottom in a coiled spring 31 and for adjustment and slide together with any desired degree of friction; The top of the second telescoping member 25 is provided with a projecting head or projection 33 so that when it is allowed to move down to the bottom it will be stopped from sliding through the tube 10. This is the position that it assumes when packed for carriage or shipment.

The top of the telescoping member 26 is flattened and provided with a pivot pin 35 therethrough located horizontally. Surrounding the flattened portion is a U-shaped piece of metal 36 to strengthen it and provide a stop as will appear. Its upper surface slants as indicated in Fig. 3 and it is mounted on the telescoping member 26 in fixed position. This pivot pin 35 has pivoted on it an opposite U-shaped member 37 of sheet metal having an integral tongue 38 bent down from the slanting top in under it and constituting a spring tongue spaced from the upper slanting wall of the pivot member. This completes the construction of this part of the device. I

I can mount on this a device particularly suited for holding a drum, saxophone, or other musical instrument, but I have shown a folding music rack 40 having a rigid central member ll on which the various links of the folding rack are supported and to which they are either directly or indirectly pivoted. On the back of this member ll isa tongue 42 which is designed to slip into the space between the tongue 38 and the top of thepivot member 37 so as to fricticnally hold the rack in position thereon. The same kind of a connecting arrangement is used for drum stands and other devices to which this invention is applicable.

I will not describe the details of the folding music rack because that is well understood in this art, except that on the outer links l4: at the two ends of the rack I have pivoted a pair of clips 45- which can be swung out to the position shown in full lines in Fig.- 1 for supporting the edges of a wide piece of music. These clips are doubled back to provide integraltongues 46 located in spring contact with the bodies of these. clips 45 so that if a piece of paper is moved outwardly under the tongue it will be held thereto by friction.

On the other hand, if a piece of music that is shorter than the holder is being used these clips 45 can be swung inwardly as indicated in dotted lines until they bear against the diagonal arms 47. Then a. paper can be passed between them and these arms and it will be held thereto by friction as the arms are bent back-enough so that they comeagainst the diagonallinks l'? with a suilicicnt degree of friction to hold the music in thatway.

It will be seen, therefore, thatthis stand is folded into even smaller compass than is usual in this class of instruments, that the legs can be locked to the lower rod 10 by the gravity latch, 19 when in use, and that the telescoping sections, no matter how many are used, all fit in each other with a sliding fit which can be adjusted in a very simple manneras described. It will also be seen that the connection of'the top one of the telescopingeleinents with the pivoted music rack is a very simple one so that the latter can be put in place and removed very easily, and that a special stop or the like, is provided to limit the positive motion of the telescoping member 25, and I have also provided for holdingmusic and books larger or smaller than the width of the rack, so that they are not likely to be dislodged accidentally.

Although I have illustrated and described the invention particularly as applied to a music rack I am aware of the fact that it can be used for stands for drums, saxophones, and other instruments or at least some features of it can, without departing from the scope of the invention as expressed in the claims, and that modifications can be made in the details of construction likewise. Therefore I do not wish to be limited to all the details of construction or to the particular type of stand herein shown, but

what I do claim is 1. In a telescoping standard for a stand of the character described, the combination with a pair of telescoping members, the inner one having openings therethrough, of a. series of springs projecting through the openings in the inner member near the end thereof to come into contact with the inner surface of the larger telescoping member, and means at the end of the inner or smaller member for adjusting the force with which the springs are projected through its. walls.

2. In a telescoping standard of the character described, the combination with inner and outer telescoping members, the inner one having a plurality of slits through its walls near the bottom, of a corresponding number of flat springs therein bowed outwardly to pass through: said slits, a fixed plug in the inner member to which the ends of said springsare connected, a sliding plug at the end of said member to which the other ends of the springs are connected, and means whereby the springs can be adjusted to give any desired amount of friction against the inner wall of the outer member.

3. In a telescoping standard of the character described, the combination with inner and outer telescoping members, the inner one having a plurality of longitudinal slit-s through its walls, near the bottom, of a corresponding number of flat springs therein bowed outwardly to pass through said slits, a fixed plug in the inner member to which the ends of said springs are connected, a sliding plug at the end of said member to which the other ends of the springs are connected, a screw passing freely through the sliding plug and screw-threaded into the fixed plug, and a spring surroimding the screw for forcing the sliding plug outwardly, whereby the bowed springs can be adjusted to give any desired amount of friction against the inner wall of the lower or outer member.

i. In a. telescoping standard of the character described, the. combination with a pair of telcsco tiing members, of a. series of springs projecting through the walls of the inner member nearthe bottom thereof to come into contact with the inner surface ofthe larger telescoping member, means at the bottom of the inner or smaller member for adjusting the force with which the springs are pro jected through its walls, a. slide mounted on the outside of the lower member of the telescoping standard and provided with: a gravity hook depending therefrom, said hook having a lower surface slanting upwardly toward the standard and adapted to hang down from its pivot by gravity along the standard, a fixed pin spaced from the standard in position to be engaged by the hook when lowered and force the hook outwardly so that it is free to move inwardly by gravity past the pin, whereby if the slide is raised the hook will lock the parts in position, links connected with said slide, and legs connected with the links and with the bottom of the standard.

5. In a stand of the character described, the combination with a. pair of telescoping upright members, of a series of springs pr0- jecting through the walls of the inner member near the bottom thereof to come into contact with the inner surface of the larger telescoping member, means at the bottom of the inner or smaller member for adjusting the force with which the springs are projected through its walls, the top member of said stand having a piece of sheet metal having a slanting upper surface, and a member of sheet metal pivoted to the top of the top member and having a tongue inside it parallel with its upper surface and adapted to constitute a stop in either di rection, said stop having a space between it and the adjacent surface of the top of said pivot member for detachably receiving a tongue on a rack or the like to be sup ported thereby.

6. In av stand of the character described, the combination with a pair of telescoping members, the top member of said stand being flattened at. the top and surrounded with a Ushaped piece of sheet metal having a slanting upper surface, of a piece of sheet metal of U-sha-ped form pivoted to the top of the upper member through the first named U-shaped member, and partially enclosing the same, the second U-shaped 1nemher having an integral tongue constituting a continuation of the top thereof bent down and inside it parallel with its upper surface and adapted to engage the slanting surface of the first named U-shaped member to constitute a stop in either direction, said stop having a space between it and the adjacent surface of the top of said pivot mem-' her for detachably receiving a tongue ona rack or the like to be supported thereby.

7; As an article of manufacture, a folding music rack having a central member, a pair of diagonals pivoted thereto at one end,' and a' series of links connected with it and constituting a substantially rectangu lar figure when in fully expanded position, and apair of clips pivoted on the outer links and having reversecLtongues forreceiving sheets of paper between them and holding them frictionally, said clips being capable of being'swnng outwardly beyond the limits of thebody of the rack to hold sheets wider thanthe rack and also being capable of being swung inwardly into contact with said diagonal links-to hold narrower sheets against them.

In testimony whereof affixed my signature.-
