COMPLETE SPECIFICATION.
Improvements in Music Leat Turners.
We, LATTIMORE CARTER, and EDMUND KEMBLE, both residents of
913 Bloomfield Street in the City of Hoboken, County of Hudson, and State of
New Jersey, United States of America, Consulting Engineers, do hereby
declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
This invention relates to music turners, or to devices for turning the sheets or
pages of music; and the object thereof is to provide a device of this class which
is adapted to be connected with an ordinary music holder such as is used in
connection with pianos, organs or similar instruments; or in connection with music
stands or other supports; and with this and other objects in view the invention
consists in the construction, combination and arrangement of parts. hereinafter..
described and claimed.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, in which :-
Fig. 1 is a front elevation of my improved music turner, parts thereof being.
shown in section;
Fig. 2, is a plan view showing one end of the frame of the turner, removed,:
and,
Fig. 3, a section on line 3-3.
In the practice of our invention, we provide a plate or board A, which is:
adapted to be connected with the music holder or support of any kind, class or
form, and which is provided at the upper end with segmental cross plate, and at
the lower end with a similar cross head or plate and arranged at a predetermined
distance below the upper head or cross plate is a bearing E, through which passes
the upper end of the shaft F, the lower end of which is mounted in the cross:
head D, mounted on the lower end of said shaft is a wheel G, provided at regular
intervals with projecting arms or sprockets g, and said plate or board A, is provided:
with a transverse slot g, in which said wheel revolves.
Mounted on the upper end of the shaft F, above the bearing E, is a wheel H,
which is provided on its upper surface at regular intervals with a plurality of
radial shoulders or projections which are preferably three in number and which
are designated by 1, 2, and h, and the first of which is arranged adjacent to the
center thereof, and the second at about midway between the center and the
perimeter of the wheel and the third adjacent to the perimeter thereof.
Passing through the segmental cross head B, is a bolt or pin K, on the lower
end of which are mounted a plurality of arms which are preferably three in
number and which are designated by k', E, and but only two of which are
shown in Fig. 2, and these radial arms are provided at their inner ends with
flattened and circular heads as shown at L, whereby they are pivotally connected
with the rod or pin K, in such manner that they rest in the vertical plane, and
each of said arms is provided at its inner end or adjacent thereto with a latterly
extending shoulder or projection M, which corresponds with the radial shoulders or
projections ',, and , and the operation will be readily understood from the
foregoing description when taken in connection with the accompanying drawing
and the following statement thereof.
In practice, we prefer to enclose the upper wheel H. by a band O, and the device

page_text: is operated by means of the wheel G, which is provided with arms g, the device is
next connected with the music holder in any desired manner, and each arm K', K'
and K is connected with a sheet of music, and the sheet which it is desired to
turn first is connected with the rod or arm or the arm which is uppermost the
next with the rod or arm k, not shown and the succeeding with the rod or arm k³,
and whenever it is desired to turn said sheet, the wheel G is turned to the left, and
in this operation the radial shoulder or projection A, will strike the depending
shoulder or projection M, on the rod or arm A, and turn it one half of a revolution
to the left when it is desired to turn the rod or arm k, the wheel G, is again
operated, and the wheel H, will be turned thereby, and the radial shoulder or
projection thereon will be operated in connection with the depending shoulder
or projection M, on the rod or arm k³, and turn the latter in the same manner as
hereinbefore described with reference to the rod or arm k', and this operation may
be repeated until all the rods or arms are turned; and it will be apparent that any
desired number of arms or rods may be thus operated.
It will be seen on an examination of the drawing, that the pin or bolt K, is not
arranged in direct lines with the shaft F, said pin or bolt being preferably arranged
slightly to one side, or to the right thereof, and the object of this arrangement is
to provide means whereby the parts will operate to turn the rod or arms to the
position shown in Fig. 2 which could not be done if said pin or bolt K, was in
direct line with the shaft P. The radial shoulders or projections h¹, h³, and h³, on
wheel H, would not pass the shoulders or projections M, on the arms K', K',
and Kas said arms are turned to the left as shown in Fig. 2, if the center of said
pin or bolt K, were in direct line with that of shaft F, but by reason of the
arrangement of these parts as herein shown and described said arms h', ' or as
many of them as are provided with corresponding lugs on the wheel H, will be
operated.
The operation of the device will readily be apparent when it is considered
that pin K, upon which are pivoted the arms K', K and K', has a center different
from that of the shaft F, carrying the wheel H, upon which the radial
shoulder A', and Aare eccentrically arranged. When the wheel H is turned to
the left the lug corresponding eccentrically with the projected shoulders on the
arms will immediately engage with said shoulder and carry the arm until the same
is released by reason of the differential centers of the pin K, and that of the
shaft F.
Our invention is not limited to the exact form, construction and arrangement of
the various parts thereof, as herein described; and we therefore reserve the right
to make all such alterations therein and modifications thereof, as fairly come within
the scope of the invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The herein described music turner comprising a plate or board or other
support; bearings at each end thereof, a shaft mounted in said bearings, a wheel at
its upper end and provided on its upper surface with radial shoulders or projections
which are arranged eccentrically to the center thereof, a cross head connected with
the upper end of said plate or board through which is passed a pin or bolt on the
lower end of which is mounted a plurality of rods or arms, each of said rods or
arms being provided with a depending shoulder or projection in connection with
which the radial shoulders or projections on the wheel are adapted to operate, and
means for operating said shaft, substantially as described.
