PATEN T 0F LEWIS A. BRINKMAN, OF CHICAGO, ILLINOIS.

MUSIC-HOLDER.

To all whom it may concern:

Be it known that I, LEWIS A. BRINKMAN, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Music-Holders, of which the following is a specification.

The present invention relates generally to music holders for use in supporting sheet music and the like, and more particularly to that class of holders having collapsible and foldable stands and racks which enable the holder to be folded together into a compact parcel.

The object of the invention is to provide an improved holder of this class, which, as compared with holders of the prior art,will be stronger and more durable in service, more economical to manufacture, and relatively more compact when collapsed and folded.

To this end, it consists in certain novel features of construction and arrangement of parts which will best be understood upon reference to the following detailed description, taken in connection with the accompanying drawing, the novelty being particularly pointed out in the appended claims.

Referring to the drawing in detail, 10 designates the standard, 11 the legs by which it is supported, and 12 the rack upon which the music, or the like, is to be supported. The standard 10 is composed of a number of telescoping sectionsin the present case, five sections designated 13, 1 1, 15, 16 and 17. hen these sections are telescoped, the section 17 is outermost, and section 13 is innermost. The rack 12 is secured to the upper end of the uppermost section 13, while the legs 11 are associated with the lowermost section 17. In the present instance, three legs are employed. Each leg consists of a metal punching folded so as to provide a' U-shaped cross-section, as illustrated in Fig. 4;, and so as to provide for the inclosing of the associated braces 18. The inner end of the legs are pivoted to a collar which is made up of three punchings 19. In assembling these punchings and the legs, the pivots 20 serve both to fasten the punchings to-- gether and to pivotally secure the inner ends of the legs. The collar, formed by these punchings 19, is slidable upon the section 17 of the standard. A similar collar 21, also composed of three punchings, is secured to the section 17 near its lower end. The pivots 22, which fasten these punchings together, also pivotally secure the inner ends of the brackets 18. The outer ends of these brackets are secured to intermediate points of the legs 11 by pivot-s 23. With this construction, it will be seen that as the slidable collar, composed of the punchings 19, is moved upward, the legs 20 will be brought into proximity to the standard section 17 in much the same way that an umbrella is collapsed. In order to hold the legs distended, the punchings .19 are made with downwardly projecting portions which serve as leafspring catches. These catches are provided with suitable shoulders 24, 25, to engage the collar 21, as clearly illustrated in Fig. 2. WVhen thus engaged, the legs cannot be moved, but rigidly support the standard. In order to readily release the catches, of which there are preferably three, the lower end of the section 17 is provided.

with a ring 26 which has a limited up-anddown movement upon the section, by reason of a pin 27 secured at 1ts ends to the ring 26 and extending through the slots 28 in the walls of the tubular section. \Vhen the ring 26 is pushed upward by hand, it engages the inclined faces at the ends of the catches and causes them to disengage the collar 21 so that the slidable collar may be readily moved to collapse the legs of the device. In order that the standard may remain in the positions to which it is adjusted, its several sections frictionally engage each other. Such frictional engagement may be brought about in many different ways. In Fig. 3, however, I have illustrated one construction for providing frictional engagement. I-Iere two sections, which we may assume to be sections 13 and 14, are shown. The lower end of section 13 has a ring 29 secured to its outside. The upper end of the section 14 is contracted, as illustrated at 30, so as to closely engage the section 13. This construction provides a close fit between the overlapping portions of the two sections and prevents one being drawn out of the other. A saw-cut 31 provides the proper resiliencyto enable the sections to be drawn out or forced together.

The rack 12, as before stated, is pivotally secured to the upper end of the uppermost section 13 of the standard. As illustrated in Figs. 5 and 6, a lateral projection 32 ex tends from the upper end of the section 13 and is provided by a punching which is fitted closely about the upper end of the section 13 and extends between the projecting leaves 33 secured to the back of the central vertical member 34 of the rack by pivots 35, 36. A pivot 37 unites the projection 32 and leaves 33 and consequently provides apivotal connection between the standard 10 and rack 12. It will also be noted that in the construction here shown, the forward end of the projection 32 extends through a slot in the lower end of the central vertical member 34. Pivots 36, in addition to securing the leaves 33 to the central vertical member 34, also serve to connect the lower horizontal members 38 to the member 34. Similar upper longitudinal members 39 extend outward from the member 34, to which they are secured by pivots 40. The members 38 are also provided with outer vertical members 41, which are pivoted at points intermediate of their length to the lower horizontal members 38 by pivots 42. These outer vertical members 41 and the upper horizontal members 39 are provided, respectively, with extension members 43 and 44. The members 43 are pivoted at their lower ends to the upper ends of the members 41 by pivots 45, and the members 44 are pivoted at their inner ends to the outer ends of the members 39 by pivots 46.

These extension members 43, 44, also cross each other intermediate of their lengths and are pivoted together at such points by pivots 47. Links 48 are secured by pivots 49 to the lower horizontal members 38 at points adjacent to their inner ends. These links, together with the lower ends of the outer vertical members 41, serve to support the shelf sections 50 through the agency of pivots 51, 52. The central vertical member 34 is also provided with slots 53. These slots serve to guide and to limit the movement of pivots 54, which extend through the adjacent ends of the braces 55, 56. The upper braces are connected at their opposite ends by pivots 57 to the upper horizontal members 39, and braces 56 are connected at their lower ends to the lower horizontal members 38 by pivots 49.

I11 lieu of the construction of Fig. 3 for providing frictional engagement between the sections of the standard, I may employ the construction of Fig. 8. In this figure, sections 15 and 16 are illustrated. Section 16 is contracted at its upper end, as illustrated at 58, so as to closely engage the section 15. Section 15, in turn, is enlarged at its lower end, as at 59, so as to closely engage the inside of the section 16. A short saw-cut 60 is also made in the lower end of the section 15. A pin 61 passes through openings in the expanded portion 59 of the section 15. It is provided to engage the section which slides into section 15 and the saw-cut enables the lower end of the section 15 to yield as it is moved within section 16. The pin 61 is loosely fitted in the expanded portion 51 of section 15 so as not to interfere with its resiliency, and it is of such length as to not engage the inner surface of section 16 as the section 15 is moved within it. Section 15 is also provided, at some little distance from its lower end, with an expanded portion or bead 62 which engages the inner surface of section 16 and is adapted to abut against the contracted end 58 to stop the outward movement of section 15. Obviously, the constructions of either Figs. 3 or 8 might be used throughout the standard in order to provide proper frictional engagement between the sections, or'the construction of one figure might be employed in the case of certain sections, and that of the other in the case of other sections in the same standard. The construction of Fig. 8, however, is preferable to that of Fig. 3.

In carrying out my invention, 1 have sought to construct the rack, standard and legs in such a manner as to bring them all within a relatively small compass when the holder is collapsed and reduced to its smallest dimensions and, from the above description, it will be seen that such a device has been provided. When collapsed, the telescoping sections occupy a length substantially the same as the lowermost section. The same is true of the legs. When the central vertical member 34 is moved about its pivot 37 so as to bring its front face into engagement with the collapsed stand ard, it, too, is of a length less than the lowermost section of the standard. Likewise, a collapsing of the various members of the rack on either side of the central vertical member do not increase the length of the collapsed device beyond that of the lowermost section of the standard. In view of this, I am able, with the particular embodiment of the invention here illustrated, to construct a holder which shall have the usual size of rack and height of stand when expanded and will occupy a length of not more than twelve From the above description, it will also be seen that the horizontal members 38 and 39 are rigidly held by the braces 55 and 56. This provides a rigid and substantial structure which is bound to maintain these members horizontal, even though the.pivots be considerably worn. It will also be observed that by reason of the shelf sections being hung from the horizontal members 88, which are thus rigidly held, such sections will be maintained in alinement, even though the parts become considerably worn by use. In view of this hanging of the shelf sections, there will also be no sagging or drooping of the corners of the holder because ofwear. The weight of the book or music upon the shelf sections will tend to maintain the mem bers 41 and 43 vertical and thereby bring the horizontal extension members 44 into line with the upper horizontal members 39.
