MUSIC-HOLDER.

SPECIFICATION forming part of Letters Patent No. 794,503, dated July 11, 1905.

Application filed Septemberv 24, 1904. Serial No. 225,787.

To all?, whom, it may concern:

Be it known that I, JOSEPH HOFFMAN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Music-Holders, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide an improved music holder or support the separate parts of which may be compactly folded together so as to form a small and compact body which may be conveniently carried in the hand or in a small package of any kind; and with this and other objects in view the invention consists in a music support or holder constructed as hereinafter described and claimed. l

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which- Figure 1 is a front elevation showing my improved music support or holder in position for use; Fig. 2, a similar view showing the music supportor holder in a folded condition; Fig. 3, a transverse section on the line 3 3 of Fig. 1; Fig. 4, a similar section on the line 4 4 of Fig. 1; Fig. 5, a sectional View of the top portion of the device as shown in Fig. 1; Fig. 6, a longitudinal section of the device as shown in Fig. 2; Fig. 7, a sectional front View of the top portion of the device as shown in Fig. 1 and showing the music-rack or music-holder proper partially folded; Fig. 8, a sectional side view of the rack or music-holder proper as shown in Fig. 7 and showing the rack fully folded, and Fig. 9 a front View of the device as shown in Fig. 8.

In the accompanying drawings, Figs. 7, 8, and 9 are on a larger' scale than Figs. 1 and 2, and Figs. 3 to 6, inclusive, are on a still larger scale.

In the practice of my invention I provide a music support or holder comprising a main upright member a, composed of separate telescopi@ sections a2, co3, and cf, which are preferably tubular in cross-section, supportinglegs b, and a head or rack c, which constitutes the music-support proper. The bottom end of the bottom tubular section a2 of the main upright support a is provided with a collar, flange, or rim a5, and slidably mounted on said section a2 above the collar, flange, or rim a5 are collars a and a7. The legs in the form of construction shown are triangular in crosssection and are pivotally connected with or hinged to the collar a7, as shown at b2 in Fig. 4, and four of said legs are employed in the form of construction shown. The legs b are also connected with the collar a by links b3, which are pivotally connected with said legs and with sa'id collar, as shown in Fig. 3, and the said legs b are also provided at the bottom thereof with an inwardly and upwardly directed hook member 271, which in the form of construction shown consists of a flange or rim, as shown in Fig. 6, but which may be made in any desired manner, and in practice when the separate parts of the device are folded together, as shown in Fig. 2, the collar, iiange, or rim a5 at the bottom end of the bottom tubular section t2 of the main upright member a engages the hook members b4 at the bottom of the legs b, as shown in Fig. 6, and the parts of the device be thus locked together when in a folded condition.

As shown in the drawings, the separate parts of the main upright member a consist of closely-fitting tubular sections which may be telescoped to any desired extent and which may be provided with any suitable means for preventing their separation-such, for instance, as is shown and described in United States Patent No. 765,187, dated July 19, 1904; but my invention is not limited to any particular means for preventing the separation of the tubular section of the main upright member a, and any suitable devices for this purpose may be employed.

The head or rack o, which constitutes the music-holder proper and on which the music is placed when the device is in use in the usual manner, comprises a main central plate c2, which ranges in line with the main upright member a, two side -arms 03, pivoted to the lower end thereof, two supplemental side arms IOO ci, also pivoted to the lower end of the part c2 and to the inner ends of the arms c3, together with links c5 and c6, which are pivoted, respectively, to the ends of the arms c4 and c3 and to each other, and links c7 and 08, which are pivoted, respectively, to the upper ends of the part c2 and to the arms c4 and to each other, and the links c in the form of construction shown are shorter than the links c5, and the links es are shorter than the links c7. rlhe upper end of the part c2 of the head or rack c in the form of construction shown is provided with a forwardly-directed hook member cg, which opens downwardly and in which the parts c4 05, c7, and 08 fold when Ithe separate parts of the head or rack are folded together, as shown in Figs. 8 and 9, and the arms c3 in the form of construction shown are triangular in cross-section, and the parts of, 05, and 0y fold therein, as shown in said figures.

Secured to the back of the parts c2 of the head or rack cis a spring d, this connection being made as shown at Z2 in Fig. 5, and the spring Z is secured to a sleeve d3, which fits in and is movable in the upper section of the main upright member a, and the head c` may be compactly folded together, as shown in Figs. 8 and 9, and shoved down into said upper section of the main upright member t in the operation of folding all the parts of the device together, as shown in Figs. 2 and 6.

The upper end of the part c2 of the head or rack cis also provided with a longitudinal slot e, which extends partially through the hook member 09, and a cap f is pivoted to the up- `per end of the part c2 of the head or rack c by c means ofaheated pin f 2, which passes through the slot e, andthe cap f may be turned backwardly when the device is 'in use, as shown in Fig. l, or it may be used, as shown in Figs. 2 and 6, so as to inclose the upper ends of two parts of the device when folded together, as

. shown in said figures.

1n the form of construction shown the sleeve d3, with which the spring d, which supports the head or rack c, is connected, is provided with a cord, chain, or other flexible device g, which is secured to the bottom or in the bottom of the bottom tubular section 6L of the main upright vmember and which prevents the withdrawal of the sleeve Z3 from the upper section of said main upright member; but any other suitable means may be provided for this purpose, and in the form of construction shown the lower end of the bottom section a? of the main upright member is closed by a plate t, and the collar, fiange, or rim a5 is formed on said plate; but this collar, flange, or rim may be formed on the bottom of the section a2 of the main upright member if desired. The lower ends of each of the sections a2, a, and are also connected by iexible devices g2, which, like the flexible devices g, are of sufcient length to permit of the drawing out of said main upright member the collars r6 and a7 are moved up on said section or said section is moved downwardly through said collars until the rim a5 engages the hook members b* at the bottom of said legs. The telescopic members t3 and are then telescoped into the bottom member a2 and the head or rack c is folded together, as shown in Figs. 8 and 9, the process of folding being partially shown in Fig. 7 and also partially indicated in Fig. l, and said head or rack is then forced down into the tubular section of the main upright member a, and in this operation the cap f rests on the upper ends of the parts a2, a3, and a4, as clearly shown in Figs. 2 and 6, and the legs are locked to the lower end of the part a2 and the entire device is folded into a compact body, as indicated in Fig. 2. In order to extend the device for use, as shown in Fig. 1, the abovedescribed operation is reversed, or, in other words, the head or rack c is pulled out by grasping the cap f, and this operation if continued will also pull out the sections 3 and Y successively into the position shown in Fig. l. The outward movement of the sections a3 and is limited by the iiexible connections g and g2, as hereinbefore described. After the sleeve Z3 has been'pulled up to the top of the section the head or rack c is swung backwardly, as shown in Fig. l, and the sleeve d3 is forced downwardly a shortdistance, so that the bottom of the head or rack will rest against the top of the section and hold the head or rack in an inclined position', as shown in Fig. 5, so as to hold the music placed thereon in a more convenient position.

The collar a6, with which the links 3 of the legs b are connected, is provided with a bayonet-slot, as shown at g3 in Fig. l, and the lower end of the section with a corresponding pin movable in said slot, and in this way the collar a may be locked in the position shown in Fig. l, and in order to slide the collars a and a7 on the section a2 of the main upright member the collar a may be partially turned, and when the parts are in the position shown in Fig. 1 the collar t6 is locked to the section a2, so as to` enable the legs to operate as a support for the device.

My invention is in no way limited to the form of the separate sections of the main upright member a, nor to the means employed for holding said parts in their extended position, nor to the means employed for holding the sleeve Z3 in the section r, the invention ICO IIO

which forms the basis of this application being in the legs b, the method of connecting the same with the tubular section and in the construction of the head or rack c and the method of connecting it with the sleeve cl3.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is l 1.
