Improved Holder or Turnbutton for Securing Violin Bows in their
Cases, and for other analogous purposes.
1, JOSEPH ComEN of 132 Kirk Gate Leeds in the County of York, Manu-
facturer do hereby declare the nature of this invention to be as follows:-
The object of my said invention is to provide a simple and effective spring device
to form a holdfast for securing and retaining violin bows in proper position in their
cases the said device being also applicable to many other purposes such as for
securing doors or lids that do not require to be locked, or for use in addition to the
lock, or the device may be used as a cleat or securing pin over which a loop ring
or link may be passed and retained thereby on operating the holding portion of the
said device.
In carrying out my invention so as to be applicable for holding a violin bow
I form a narrow metallic box or casing of much greater length than width being a
parallelogram on plan and arranged to be placed between the shaft and the hair of
a bow and parallel with the same.
The bottom plate is continued a short distance beyond each end of this box or
casing forming lugs or flanges in which are screw holes for securing the device to
the lid or other part of the violin or like case. The sides and ends are of convenient
height according to the size of the bow to be held.
Within the metal box or case and at each end thereof I form an upright boss or
pillar centrally situate between the two sides of the box and leaving a space on
either side between the boss or pillar and the sides of the metal box in which
spaces rest the ends of two pieces of flat steel or like band slightly longer than the
interior of the box and bent so that when placed loosely in the box with their
convexities back to back they form a double spring.
Centrally on and in the bottom plate I pivot or mount so as to revolve when
turned by the hand a pin or arbor continuing upward through the lid of the metal
box and terminating in a square or shouldered extremity on which is rigidly
secured a turnbutton of convenient length and width say corresponding with the
length and width of the top plate of the box. The shaft of this arbor is of greater
thickness within the box and of peculiar shape that is to say of an oval or egg
shaped section with the ends flattened, the turnbutton being so fixed as to be at
right angles to the sides of the oval.
This oval sectioned shaft stands between the two springs which impinge on it
and retain it and the turnbutton in either of two position, i.e. with the turnbutton
parallel with the box, when the holder is inoperative or at right angles thereto
when the bow is retained in its place.
The tops of the bosses and the top plate or lid of the box have holes for screws
by which the said plate or lid is secured.
It will be seen that when the flattened or narrow portion of the arbor rests
between the springs the turnbutton stands normally across the device and is
operative. On turning the flat small ends across the box the button then being
parallel and inoperative the springs exert more pressure and the tendency of the
device is to return to its operative position across the box so that a slight touch
will effect this whereas more pressure is required to turn the button in the opposite
direction.

Improved Holder or Turnbutton for Securing Violin Bows in their
Cases, and for other analogous purposes.
I, JOSEPH COHEN of 132 Kirkgate Leeds, in the County of York, 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:-
The object of my said invention is to provide a simple and effective spring device
to form a holdfast for securing and retaining violin bows in proper position in their
cases the said device being also applicable to many other purposes such as securing
doors or lids that do not require to be locked or for use in addition to the lock, or
the device may be used as a cleat or securing pin over which a loop ring or link
may be passed and retained thereby on operating the holding portion of the
said device.
In carrying out my invention so as to be applicable for holding a violin bow
I form a narrow metallic box a, or casing of much greater length than width being
a parallelogram on plan and arranged to be placed between the shaft and the hair
of a bow and parallel with the same.
.
The bottom plate is continued a short distance beyond each end of this box or
casing forming lugs or flanges, in which are screw holes for securing the device to
the lid or other part of the violin or like case.
The sides and ends are of convenient height according to the size of the bow to
be held.
Within the metal box or case and at each end thereof I form an upright boss or
pillar c. centrally situate between the two sides of the box and leaving a space
on either side between the boss or pillar and the sides of the metal box in which
spaces rest the ends of two pieces of flat steel d. or like band slightly longer than
the interior of the box and bent so that when placed loosely in the box with their
convexities back to back they form a double spring.
Centrally on and in the bottom plate I pivot or mount so as to revolve when
turned by the hand a pin or arbor E, continuing upward through the lid of the
metal box and terminating in a square f. or shouldered extremity on which is
rigidly secured a turnbutton C, of convenient length and width say corresponding
with the width and length of the top plate H. of the box. The shaft of this arbor
is of greater thickness within the box and of peculiar shape, that is to say, of an
oval or egg shaped section E, with the ends flattened the turnbutton being so fixed
as to be at right angles to the sides of the oval.
This oval sectioned shaft stands between the two springs which impinge on it
and retain it and the turnbutton in either of the two positions i.e., with the turn-
button parallel with the box when the holder is inoperative and at right angles
thereto when the bow is retained in its place.
The tops of the bosses and the top plate or lid of the box have holes for screws
by which the said plate or lid is secured.
It will be seen that when the flattened or narrow portion of the arbor rests
between the springs the turnbutton stands normally across the device and is
operative, on turning the flat small ends across the box the button then being
parallel thereto and inoperative the springs exert more pressure and the tendency
of the device is to return to its operative position across the box so that a slight
touch will effect this whereas more pressure is required to turn the button in the
opposite direction.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed 1 declare that what
I claim is
That the novelty of my said invention lies in the flattened ends of the elliptical
arbor E, which locks when operative and also when inoperative.
