- EMERSON O. STRANGE, OF TAUNTON, MASSACHUSETTS.
SPECIFICATION forming part of Letters Patent No. 230,446, dated July 2'7, 1880.
Application filed November 25, 1879.
To all whom it may concern:
Be it known that I, EMERSON O. STRANGE, of Taunton, State of Massachusetts, have invented an lnlproved Music-Rack, of which the following is aspecification.
The object of my invention is to provide an inexpensive means of changing the position of the supporting-rack relatively to its supporting-rod and the invention consists in a head suitably formed to be secured to the supporting-rod, and having two planes oblique to each other, and which in their width are formed tapering from their base or lower end upward, and having beveled or retiring edges, which interlock in a corresponding slot formed in the rack, which is thereby secured in position and supported.
Figure 1 is a side elevation of my invention as secured to a chair. Fig. 2 is a vertical section as taken on line Y Z, Fig. 1, with the chair omitted, and showing the pivoted socket and lower part of the tube in longitudinal section. r Fig. 3 is a vertical section as taken in the axis of the sliding rod i, and showing said rod, the upper portion of the tube in which it slides, and the socketed head formed with twoplanes, secured upon the projecting end ofsuch rod. Fig. dis a transverse section as taken on line W X, Fig. 1, showin g the said planes and the taper slot'or groove in the rack m, which engages the said planes. Fig. 5 is a top or plan view of one of the said planes, and showing the socket and part of rod 1'.
In these views, a represents the seat of the chair. I) is the clamp, which issecured to the chair by the screw 0. d is a circular base, from which socket eproceeds. This base rests upon a corresponding bearing formed on clamp b, and is thereto secured by thumb-screw f. 4.0
g is a tube, secured in socket e, and at its upper end it is provided with the thumb-screw h, by which to lock in place rod i, which slides in the tube.
j is a socket, in which rod '11 is secured, and 5 as an extension of which two planes, k l, are formed, tapering or with converging side or edge lines, as shown in Fig. 5, and with undercut or beveled edges, as shown in Fig. 4, while the holding-rack m at its central part, a, is provided with a slot or seat formed to correspond with and to receive either of said planes, as shown in Fig. 4.
By removing rack m and reversing rod i that is, turning it half a circle in tube g-the 5 5 position of the rack when replaced will be changed in its relation to a horizontal line to the extent of the diversity of obliquity of said planes relatively to the axis of rod i.
I claimas my invention-- In a music-rack and book-holder, the adjustable rod i, having a head provided with planes k l and arranged oblique to each other, and formed with undercut and converging edgelines, and a rack having a recess or seat to interlock with such planes, substantially as specified.
