ALBERT KRAFFT, or BERLIN, PRUSSIA, AssIeNon-To F. e. UTASSY & 00.

OF NEW YORK CITY.

Letters Patent No. 169,023, dated November 8, 1870.

. IMPROVEMENT IN MEDIUM$ FOR TURNING MUSIC-SHEETS.

The Schedule referred to in the Letters Patent and making part of the lame.

Be it known that I, ALBERT KRAFFT, of the city of Berlin, Prussia, have invented a new and improved .Medium for Turning Music-Sheets; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in theart to make and use the same, reference being bad to the accompanying drawing forming part of this specification.

This invention relates to improvements in devices for holding and turning the leaves of music-books and It consists-- First, in combininga stand with an adjustable support and an adjustable treadle-rod, so that the height of the music may correspond to the height or choice of 'difi'erent' persons.

Secondly, in the peculiar construetion'aml combina' tion of the fingers and sliding rack.

In the accompanying drawing- Figure 1 represents a side elevation of the arrangement.

Figure 2 is a section of fig. 3 from the line a: x.

Figure 3 is a sectional front view.

Figure 4 is a detail top view, looking down from the line y y'of. fig. 3.

Similar letters of refierence indicate corresponding parts.

. A is a stand, upon which rests (or to which is attached)'t he column B, which column is formed of two parts, and made adjustable by means of a telescopejoint and set-screw, as seen at O.

' D-is aframe, attached to the top of the column B, as seen at E, which frame, supports the music sheet or'book.

Attached to the top ofthe frame 1) is a bracket, 1*, with ears G G projecthig' outward, through which ears there passes a central. pin, H, onwhieh the eyes .[of the fingers J turn, as; they turn the sheets from right to left for reading the music.

K represents the music-sheets.

On each of the finger-eye's there is a projecting lug, L.

- M is a rack, which slides longitudinally with the bracket 1* directly back of'the eyes.

\Vhen this slide is down it holds the fingers to the right by means of the ing L and-a. rib, L, on its side or hack..

As the slide is raised, the ,rib leavesthe lug' on the lower finger first, and so on, suocesstv ely, for all the fingers, which, as they-are thus released, turn the leaves.

. The fingers are actuated by springs, one spring for each finger, confined ;to a stud on one side of the bracket.

F N represent the springs.

The springs receive their tension when the finger is adjusted to the sheet of music, as seen at O, fig. 3.

The end of each finger is flattened, or a thin nipper or holder, P, is attached thereto, for holding the sheets or leaves.

The sliding rack M is operated by means of a pinion, R, and pawl, S.

' The pawl is attached to the arm .'I, which works on the arbor of the pinion.

U is an adjustable rod, which is attached to theeud of the arm 'l. Itextends down beneath the column B, and is attached to one.leg of the stand, as seen at V.

W is a knob. .whieh passes through a slot in the leg.

. X is a spring, which bears upward against the rod By pressing with the foot or toe of the shoe on the knob the rod U will be drawn down, which causes the pawl to engage with the pinion. This movement raises" the slide and liberates the fingers, one at a .of music may be turned by the performer without the least interruption, and in the shortest possible space of time.

Having thus described my invention,

I claimas new and desire to secure by Letters Patent- 1. The combination of music-holder D with adjust able support B and adjustable rod U U, as and for the purpose describech 2. The spring-fingers J N, having eyes Iantl lugs L, pinion Rfpawl S, arm T, spring Y, and lever U, all

constructed and relatively firranged as and for the purpose described.

The above specification of my invention signed by me this 13th day of December, 1869.

-ALBERT KRAFFT.
