Improved Apparatus appertaining to Music Stands.
I, JAMES HURLEY, Junior, of No. 90 Glebe Road, Glebe, in the City of
Sydney, Colony of New South Wales, Australia, Storekeeper, do hereby declare
the nature of my invention for "IMPROVED APPARATUS APPERTAINING TO
MUSIC STANDS," and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
-
My invention consists in the adaptation and use of various mechanical parts
whereby the operation of turning over the leaves of music may be accomplished
without the necessity for the musical operator relinquishing his, or her, musical
performance to engage in the adjustment of the leaves of the music score. My
apparatus is so adjusted that the turning of the leaf may be accomplished by a
simple pressure of the hand or foot of the operator, and after reversing the leaf, the
apparatus returns automatically to the next leaf.
To accomplish these movements I construct my apparatus with the following
mechanical parts.
A case or cylinder attached to a folding frame representing the covers of a music
book. This frame is made preferably in skeleton form, the outer portion of which,
together with the transverse bars, are made to telescope, so that, if desired, it may
be expanded to suit the varying sizes of music scores. The cylinder encloses a
spiral spring, and, a spindle having on its lower end a screw of the requisite pitch
suitable for producing quick action, with a nut fitted thereon, such nut being
also attached to a lever whose fulcrum is formed upon the lower end of the said
cylinder.
The upper end of the spindle carries a fixed collar, and when within the case
such fixed collar receives the top pressure of the spiral spring, while the nut before
referred to receives the downward pressure of the spring, a stop being provided to
prevent the nut being pushed out of its position. The nut is further provided with
projections or guides running in grooves formed in the lower part of the cylinder, to
prevent it rotating within the cylinder.
The top of the casing receives the thrust or pressure of the fixed collar of the
spindle, and to it is attached another collar having a spiral surface, a corresponding
collar, also provided with a similar spiral surface, being securely attached to the
upper end of the spindle, and sliding upon a fixed feather in the spindle. Above
this last mentioned collar is a small spring which is confined between the ornamental
finial of the spindle, and the collar, for the purpose of keeping the mechanical parts
attached to that end in position, and also to assist the return motion of the movable
arm hereinafter referred to.
The topmost collar carries a fixed arm provided with an adjustable extension
piece having on its outer end a pendant rod of sufficient length to admit of its
engaging with a special form of clip, called a leaf clip, which is attached separately
to each leaf of music. The innermost end of this extension piece is inserted in the
fixed arm, which is hollowed out to receive a spiral spring so placed therein that it
shall exert a thrusting pressure upon a collar fixed to the extension piece. An
advancing and receding movement is imparted to this extension piece by means of
a pin attached thereto and sliding in a groove formed on the under side of the fixed
arm, such pin coming in contact with a suitable guide plate fixed to the top side of
the folding frame. The receding movement is obtained by the pin pressing against
the inner edge of the guide plate until the arm occupies its restful position, when the
end of the guide plate will be reached, and the pressure of the spring will cause the
advancing movement to take place, and the pin will then occupy a 'position in: a

page_text: line with the outer face of the guide plate, along which face it will travel when the
next folding operation takes place.
Another method of performing the advancing and receding movements of the
adjustable extension piece may he accomplished by providing a connecting rod
attached to an eccentric secured to the upper end of the spindle either through the
fixed arm or in any convenient position above or below the arm. By means of
this attachment the pendant rod attached to the extension piece is made to occupy
a position suitable for entering the leaf clip, which it will do automatically as
soon as the return motion has been completed. The spring enclosed in the
socket of the fixed arm, as before described, is also used in conjunction with
the eccentric movement to assist the seating of the pendant rod within the
leaf clip.
The pendant rod attached to the adjustable extension piece is allowed to
oscillate for the purpose of causing it to release itself from the clip after the leaf
has been turned over, and when it is desired to cause it to return to the leaf carrying
the clip to be engaged next.
To provide against the possible disarrangement of the newly turned leaf when
the pendant rod is leaving the leaf clip, use a folding leaf binder which is
preferably attached to the folded side of the frame, and operated by means of a
lever, a connecting rod, a spiral spring, and, a movable guide pin sliding in a groove
formed in the top bar of the folding frame. This pin is set in motion by means of
a suitable guide plate attached to the under side of the fixed arm, such guide plate
operating only at a time when the leaf is being folded, and cansing the pin to move
towards the cylinder, thus operating the lever and the clip so that the latter
will offer no impediment to the folded leaf. The aforesaid guide plate is so
constructed that when the folding arm has completed the folding operation the
guide pin shall pass into a suitable groove which will allow of its immediate return
to its normal position, thus bringing the leaf binder over the edge of the newly
folded leaf.
I have a variety of methods for accomplishing this.
In one method the binder is pushed beyond the outer top corner of the folded
side of the frame just as the leaf is about to be deposited, and is made to return and
secure the leaf as the return action of the arm commences.
In another method the binder is made in the form of a bell crank lever, one
part of which is attached to the eccentric rod, the other part falling in front
of the leaf.
In the other method 1 provide the binder, which is placed preferably about
midway on the top of the folded side of the frame, very much in the form of an
ordinary spring paper clip, having an oscillating movement, so that it may be made
to assume a horizontal position and be quite clear of each fresh leaf, but folding
over and grasping it as the fixed arm retires.
In each of these appliances the same method of connecting with a rod and
eccentric is employed.
My invention is illustrated by the accompanying drawings, in which similar
letters are used throughout the different views to indicate similar parts, and
in which

The manner of operating my invention is as follows:
:-
The frame or music stand, A. A. with the cylinder B. centrally attached
thereto, is placed upon the ordinary music rest of a piano if used in conjunction
with a
piano, but it may be used as an independent stand, and the music score
placed thereon.
The leaf clips Y. are attached to each leaf alternately in such a position as will
enable the pendant rod U. of the adjustable extension arm T. to engage with them.
The apparatus is then ready for operating.
The clip Y. being provided with the socket Y¹ so constructed as to loosely fit
the pendant rod U. the fixed arm, S. in its normal or starting position is set in
association with the extension piece, T. so that the pendant arm, U. is resting
in the socket, Y', of the clip, Y. U is retained in this position by means of the
spring, V. pressing against and seating the collar, T' within the socket S¹.
Simultaneously the pin W; which moves in the groove W', is brought in a line
with the outer edge X' of the guide plate X. The apparatus is now ready to
commence the folding operation.
The cord K. attached to J, moving in G, causes an upward movement to be
imparted to F, which is kept from rotating by F¹ running in F. E, being inserted
in F and also forming part of D, causes D to rotate; as F is moving upward
pressure is put upon C, which is also exerting its influence against the under side
of M. P, being attached to D upon P', as D revolves, it is carried with it, and as
the rotary movement continues it gradually rises upon the spiral surface of O, a
slight resistance being offered to this rising movement by Q. By the time the
revolution is completed, P. has risen to its maximum position upon O, thus raising
simultaneously U so as to disengage it from Y'. Just before this is accomplished,
Z of Z, which is attached to S, has begun to operate f, pressing it over towards B,
thus putting e. in tension and operating d. attached to b, causing it to oscillate
upon c. so that a. is moved outwards from A. Simultaneously with the completion
of the action of S and the maximum rising of P. upon O, and the release of U.
from Y, enters Z in Z, and, by the rebound of e, f, d, and b reverse their
movements and cause the return of a. which then grasps the newly folded leaf.
The operator may then release K, when the whole of the before mentioned parts
contained within B will operate in the reverse direction by reason of the pressure
exerted by C, and thus cause S, with T, to return to its original position, P
gradually descending upon O, being assisted by the pressure exerted by Q. W is
then brought in contact with X¹ of X, and U of T retired so as to be clear of Y'.
W travels along till it reaches the end of X when it is released by the pressure
of V operating T', thus U is propelled into Y¹, and is again ready to perform
another folding operation.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. A music stand provided with a folding telescoping frame, which can be
adjusted to suit the different sizes of music scores or sheet music, and to which is
attached a cylinder or tube enclosing a spiral spring, and, a spindle suspended
centrally therein and retained in its position by means of a collar which receives
the upward thrust of the said spring, the lower end of the spindle being provided
with a screw and nut, the nut receiving the downward thrust of the spring, the
said collar and nut being retained in position by means of an upper and lower
cap, the said nut having imparted to it an upward movement whereby the said
spindle is made to rotate for the purpose of producing a horizontal and
vertical movement to an arm attached to that portion of the spindle standing
above or outside of the said cylinder, as described and shewn and for the purposes
set forth.
2. In a music stand as described in Claim 1, a collar and fixed arm placed upon
a central spindle, such collar being provided with a spiral surface running upon a
similar spiral surface formed upon a fixed cap, the said spiral surfaces being
kept in contact with each other by means of a spiral spring placed above the
said collar, the aforesaid spiral surfaces imparting or producing a rising or falling
movement to the fixed arm as it rotates by the action of a sliding nut attached
to the lower end of the spindle, as described and shewn and for the purposes
set forth.
