FRANCIS L. BECKER, OF GALVESTON, TEXAS.
MUSIC-LEAF TURNER.
SPECIFICATION forming part of Letters Patent No. 225,550, dated earlch 16, 1880.
Application filed Decmber I1, 1879.Tob acl ,hom it mayy conersi:
Be it known that I, FRANcls L. B CiEi, of
Galveston, inl the county of Galveston and
State of Texas, have invented certain new andl
s useful Improvements in Apparatus for Turn-
ing Leaves of Sheet-Music, Music-Books, aind
other Books; and I do hereby declare the fbl-
lowing to be a full, clear, and exact descrilp-
tion of tlheinventio snuchb as will enable others
io skilled in the art to which it appertains to
make andl use the same, reference being had
to the accompanying drawings, and to letters
of reference marked thereon, which form a part
of this specification.
15 In the accompanying drawings, Figure I
represents a plan view of my appa ratus, show-
ing Ihe operating mechmlism attacled to the
supporting-firane, which latter also has the
function of a portfolio. Fig. 11 is anl enlarged
20 plan view of the pulley mechanism with the
lever for turning the leaves. Fig. III is a side
elevation of the same. Fig. IV is an enlarged
plan view of the mainspring mechanism and
left-hand leaf-holder. Fie'. V is a side eleva-
25 tion of the same. Fig. VI is a cross-section
on line x x of Fig. IV. Fig. VII is a side view
of the stop-pin and the holding mechlanism of
the lever. Fig. VIII is a detail view of the
arm connecting the lever and pulley. Fig.
30 IX is a horizontal cross-section through line y
y of Fig. VII. Fig. X is a plan view of the
pulleys and operating mechanism attached to
a piano or similar instrument. Fig. XI is an
edge view of part of the portfolio in a closed
35 position. Fig. XIis aview of aleaf of music
prepared for the reception of the lever, the iat
ter being shown in two positions.
In the drawings, A A' represent the two
sides of the portfolio, united by a back, 1B B',
40 made as plainly shown inl Figs. III and XI.
To the lower part of the back B B' is secured
a bracket, b, in which is journaled a shaft, b',
for the reception of the pulleys c' and c", pref-
erably made in one piece.
45 Upon the inner end of shaft b', which is
made square, is secured the arm l, leaving a
slotted lug, cdiat its ounter ind, to which one
end of the compoundelbow-leverC is attached.
This lever consists of a flat bar, C', curved and
50 pointed at its ounter end, so as to readily pass
in behind the prepared music.An adjustable angle-piece, C"', is attached
to the lower end of side A,by which the height
of tihe lever C is regulated when in its normal
state. On the left- hand side of A' is a loop, 55
C, by which the lever C is held previous to
closing the fiolio, or whoe the folio is attached
to the operating mechanism oi the piano or
Imusic-stand. A shield, C, prevents wear of
the point of the lever C oni the folio. To the 60
lover-bar C' is secured a smaller lever, C", run-
ning nearly parallel with the former, which
passes ol tlhe front of the leaf, the two levers
thus holding the leaf in between them.
At tile points of the elbow of lever C is at- 65
taced the arm I), connected thereto by a ball-
anld-socket joint, D", while the other end is
similarly attached to the pulley c" by socket-
joint c. A small stop-pin, c', in pulley c"
checks the movement of lever C when in its 70
upright position.
Both balls on the connecting-arm D are held
in position in their sockets by pivoted springs
d" d"'. A stop-pin, , e, entering the hole e' on
the end of a spring, e", secured to the arm d, 75
serves to hold the lever C in anl upright posi-
tion on the left-halnd side, when it is desired to
play a "da capo," to turn the lecaf back to its
original position.
A pivoted lover, i attached to the arm d, 8o
and a spiral spring, f', on the bracket b, serve
to retain the lever C, while in its upward or
downward motion, against the leaf.
A pulley, is journaled on the bracket
b to the right of pulley c', and over said pul- 85
icy y passes a cord, hi, one end of which is
secured to pulley c', while the other is fast-
ened upon a hook, i', on the segment i, secured
to the upright shaft E. This shaft passes
through the piano between two keys, and 9go
has on its lower end a pulley, a, of reduced
size, to whicl, again, a heavier cord, a', is at-
tached and secured with the other end, hav-
ing a loop, to the knee-lever a", pivoted to the
bottom of the piano, as best shown in Fig. X. 95
Another cord, :, is attached at one end to tlhe
small pulley c", running in opposite direction
to cord t, and is looped on the bent end of a
connecting-wire, F, this wire running through
a guide, k', to the left. The wire F is there ioo
again slightly bent upward, and to this end a
cord, t, is looped. The cord 1 passes over a
