PROVISIONAL SPECIFICATION.
Improvements in Fingers or Clips for Music Holders and the like.
I, THEODORE BROOKE JONES, of Deneholme, Harrogate, in the County of York,
Chartered Accountant, do hereby declare the nature of this invention to be as
follows:-
My invention refers to improvements on my previous Patents Nos. 12891
and 29265 both in the year A.D. 1897, and the object of my present invention
is to construct clips or fingers for music holders in such a manner that they may
be turned in the ordinary way and held in position by friction as described in
my Patent No. 12891 above referred to, or they may be allowed to balance as
described in my later patent, the change from one form to the other being effected
in a simple and expeditious manner.
According to my invention I employ a barrel having a shoulder on its outer
end with a screw thread on its exterior surface, and an interior shoulder is also
provided to act as a seat for a spring. A spindle, having a milled head on its
exterior end is inserted in the barrel, and a smaller head at the opposite end holds
a spring in compression against the interior shoulder, and tends to keep the
milled head in contact with the external shoulder of the barrel. The milled head,
is provided with a distance pin and a recess is formed in the external shoulder to
receive the pin when it is desired that the milled head shall press towards the
shoulder. A finger or leaf holder having a balance weight at its lower end, is
fulcrumed on the spindle, in such a manner that the said finger is free to swing
when the pin holds the milled head away from the external shoulder, but when
the pin is allowed to enter the recess the centre of the finger is gripped and it
can then be turned to any desired position where it is simply held by friction.
If desired, soft washers may be provided for the purpose of preventing noise.

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
My invention refers to improvements on my previous Patents Nos. 12891
and 29265 both of the year A.D. 1897, and the object of my present invention
is to construct clips or fingers for music holders in such a manner that they may
be turned in the ordinary way and be held in position by friction as described
in the Specification of my Patent No. 12891 before referred to, or they may be
allowed to balance as described in the Specification of my Patent No. 29265, the
change from one form to the other being effected in a simple and expeditious
manner.
In order that my invention may be clearly understood, I will proceed to describe
same with reference to the accompanying drawings, in which similar letters refer
to like parts in all the figures.
Figure 1 is a longitudinal section and Figure 2 is a front view partly in section,
of a leaf holder constructed according to my invention, and Figures 3 and 4 are
enlarged views of detail parts. Figures 5, 6, 7 and 8, are views of modified
forms of my invention.
A is a barrel having internal and external shoulders B and C on one of its
ends, the internal shoulder B forming a seat for a spring D. E is a spindle having
a milled head F at one end, and a smaller head G is provided at its opposite end
for the purpose of holding the opposite end of the spring D, which is carried
on the spindle E. H is a distance pin which is mounted on the shoulder C of
the barrel A, and a recess K is formed in the head F, for the purpose of receiving
the said pin H when it is brought opposite the said recess. Lis the finger or
leaf holder which carries a weight M at its lower end, and the centre of the said
leaf holder L is fulcrumed on the spindle E on which it is free to swing. R is a
slot in the leaf holder L, through which the pin H passes, thus enabling the said
leaf holder L to swing to the required distance on either side as desired.
When the leaf holder L is required to swing so as to recover its vertical position
automatically, the head F is placed in the position seen at Figure 3, by drawing
out the said head F and turning it slightly in either direction, when the distance
pin H will hold the said head out away from the shoulder C. The leaf holder L
is thus free to turn and swing on its spindle E, and the slot R enables the said
leaf holder to swing a quarter of a revolution to the right or to the left as desired,
the movement being limited by means of the pin H.
Should it be desired to employ the leaf holder L as an ordinary one to be
retained in position by friction, the head F is turned until the recess K is brought
in front of the pin H, which latter then enters the said recess and allows the
spring D to press the head F towards the shoulder C as seen at Figure 4, thereby
nipping the central portion of the leaf holder L between the two surfaces, and
enabling the leaf holder to turn with ease and to remain clamped in the position
in which it is set.
In the modifications shewn at Figures 5, 6, 7 and 8, the pin H, slot R, and
recess Kare dispensed with, and in place of the said parts I form the barrel A
with a slot S having a shoulder T in same of similar construction to that employed
in a bayonet joint. A pin V is provided on the head G, in such a manner that
it is free to slide in the slot S and when the milled head F is withdrawn and
turned, the said pin V enters behind the shoulder T, and thus holds the head F
away from the shoulder C, with the result before described.
Figure 8 is constructed in a similar manner, with the exception that a clip X
is employed for the purpose of attaching the leaf holder to the music holder, thus
allowing its position to be adjusted to suit the width of any music or the thickness
of any book desired to be employed.
If desired, felt, leather, or other washers may be placed on the spindle between
the leaf holder and the adjacent surfaces, for the purpose of preventing the
slightest sound arising from the movements of the leaf holder.

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. In a leaf holder having a weight at its lower end, the combination of the
spindle E, carrying a head F, barrel A and parts connected therewith, the spring D,
and a suitable distancing arrangement, substantially as and for the purposes set
forth.
2. In a leaf holder having a weight at its lower end, the combination of the
spindle E, barrel A and parts connected therewith, the spring D, pin H, slot R,
and a suitable distancing arrangement, substantially as and for the purposes set
forth.
3. In a leaf holder having a weight at its lower end, the combination of the
spindle E carrying a head F, barrel A and parts connected therewith, the spring D,
slot S, shoulder T, and pin V, substantially as and for the purposes set forth.
4. The general arrangement, construction and combination of the various parts,
forming my invention for improvements in fingers or clips for music holders and
the like, substantially as and for the purposes set forth, with particular reference
to the accompanying drawings.
