PROVISIONAL SPECIFICATION.
A New or Improved Device for Turning over the Leaves of Music and
the like.
•
1, FREDERICK JOHNSON ALLISON, of 23, Gordon Street, Plaistow, Paint Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to a device for turning over the leaves of music and the
like, and has for its object to provide an arrangement which will allow the leaves
to be turned over in an easier manner than is at present the case.
The arrangement I propose to employ consists of a series of arms, these arms
being pivoted at one end to a central pin. To the free ends of these arms exten-
sions are fitted, these extensions being preferably pivoted, so that they can be
turned up. These extensions engage between the leaves of the music, these being
placed at the bottom of the music support. To turn the arms round a toothed
quadrant is employed for each arm, the pivoted end of the arm being provided
with a small toothed wheel which engages with the quadrant. Each quadrant is
pivoted to a second pin placed a short distance from the central one, so that on
turning the lever to which the quadrant is attached, the corresponding arm will
be turned from right to left, or from left to right.
To operate the arms the end of each lever is provided with an extending arm
which can be turned towards the front, the arm being preferably pivoted so that
it may collapse easily. This extension projects to the front of the music stand so
that it can be easily actuated, being preferably pulled forward when it is desired
to turn the music. All the parts can be collapsed together into a box or into a
small space at the bottom of the stand, and there are no springs to get out of order.

COMPLETE SPECIFICATION.
A New or Improved Device for Turning over the Leaves of Music and
the like.
I, FREDERICK JOHNSON ALLISON, of 23, Gordon Street, Plaistow, Paint Manu-
facturer, 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 a device for turning over the leaves of music and the
like, and has for its object to provide an arrangement which will allow the leaves
to be turned over in an easier manner than is at present the case.

page_text: The arrangement I propose to employ consists of a series of arms, these arms
being pivoted at one end to a central pin. To the free ends of these arms exten-
sions are fitted, these extensions being preferably pivoted, so that they can be
turned up. These extensions engage between the leaves of the music, this being
placed on the bottom of the music support. To turn the arms round a toothed
quadrant is employed for each arm, the pivoted end of the arm being provided
with a small toothed wheel which engages with the quadrant. Each quadrant is
pivoted to a second pin placed a short distance from the central one, so that on
turning the lever to which the quadrant is attached, the corresponding arm will
be turned from right to left, or from left to right.
To operate the arms the end of each lever is provided with an extending arm
which can be turned upwards the front, the arm being preferably pivoted so that
it may collapse easily. This extension projects to the front of the music stand so
that it can be easily actuated, being preferably pulled forward when it is desired
to turn the music. All the parts can be collapsed together into a box or into a
small space at the bottom of the stand, and there are no springs to get out of order.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings, in which Fig. 1 is an elevation of my
improved apparatus, and Fig. 2 is a plan of the same with the parts removed.
The arms A are pivoted at the centre to the pin B on which they turn hori-
zontally. The arms can be turned from right to left or vice-versa and to the outer
ends of the the exten in pre pivoted. These extensions can be turned
vertically so as to project between the leave, of the music at the lower corner.
The bosses or pivoted ends of the arms are provided with the toothed wheels a¹
and with these toothed wheels the quadrants C engage. These quadrants are
formed on the ends of the arms c which are pivoted to the pin D. This pin is
placed at the side of the apparatus and the quadrant on being turned around the
pivot will cause the arm A to turn in the manner desired.
The levers are provided with the extending arms c' which are pivoted and can
be turned up or collapsed out of the way when not required. These arms form
handles which can be pulled when it is desired to turn the leaves. On pulling the
handle forward the arm to which it belongs will operate and will turn over the
leaf immediately in front of it.
Having now particularly described and aseertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
(1) In an apparatus for turning over the leaves of music and the like, the com-
bination with arms adapted to engage with the leaves, and toothed wheels or parts
on the said arms of levers carrying toothed quadrants engaging with the teeth on
the arms and means for operating the said levers substantially as described and for
the purposes specified.
(2) In an improved device for turning over the leaves of music and the like,
the combination with pivoted arms, extensions on the said arms adapted to engage
with the leaves, and toothed wheels at the pivoted ends of the arms, of levers one
for each arm pivoted at one side of the device, quadrants on the said levers engag-
ing with the toothed wheels, and pivoted arms or handles belonging to the levers
substantially as described and shown and for the nurnoses specified.
