I FREDERICK WILLIAM LEVIERGE of 8 St. James Buildings, Rosoman Street
Clerkenwell in the county of Middlesex, Maker of Model Engines do hereby declare
the nature of this invention to be as follows:-
A combination of an angular packing piece and parallel packing pieces and a lock-
nut so arranged as to permit of adjustment to the various anatomical facile conforma-
tions of different performers. It also includes an improved dovice for clamping the
chin rest to the Violin consisting of a right and left hand (male) screw working
respectively in right and left hand screwed sockets in the clamping pieces thus pro-
viding an increased range for clamping on Violins of various thicknesses. Reference
being had to the accompanying drawing.
In the drawing Fig. 1 represents a front view, Fig. 2 a side view and Fig. 3 a plan
of the same Fig. 4 shews the parallel packing pieces C and Fig. 5 shews the angular
packing piece B. By inserting the angular packing piece B an inclined adjustment
can be obtained in any direction. If however an angular position is not required the
angular packing piece need not be used but some of the parallel pieces C the slot G
allowing the pieces to be inserted without removing the chin board A. F is a lock
nut by which every part may be tightened. Should the chin board A not be in the
proper position when tightened up one or more of the thin parallel pieces C can be
inserted until the requisite position is obtained when screwed up tight. E Figs. 1 and 2
shews the right and left hand (male) screw working in sockets on the clamping pieces D
and D. The screw E and lock nut F are turned by inserting a lever into the holes
shewn.

An Improved Adjustable Chin-holder for Violins or Violas.
I, FREDERICK WILLIAM LEVIERGE of 8 St. James Buildings, Rosoman Street,
Clerkenwell, in the County of Middlesex, Maker of Model Engines, do hereby declare
the nature of this invention and in what manner the same is to be performed, to he
particularly described and ascertained in and by the following statement, reference
being had to the accompanying drawing forming a part of this specification:
My invention relates to chin-holders for violins or violas and the object of my
invention is to provide the said chin-holders with means whereby the position of the
chin-board can be readily adjusted, vertically, radially or to an angle in any direction,
and also to provide the said chin-holder with improved means for clamping it to the
violin or viola.
My improved chin-holder is secured upon the instrument by means of a clamp con-
sisting of top and bottom clamping pieces, each provided with an elongated socket, in
which sockets are formed respectively right and left had female screws, the two
clamping pieces being connected by a right and left hand male screw, working in the
said sockets. The upper clamping piece has in the centre of its upper face a vertical
screw which takes into a tubular, screwed socket freely jointed to the chin-board. An
angular or wedge shaped adjustable packing-piece fits around the said tubular socket,
under the chin-board, against which it can be clamped in any position by means of a
lock-nut screwing upon an external thread formed on the tubular socket. The lower
surface of the said angular packing-piece is horizontal but its upper surface is sloped
or inclined at the desired angle. By turning this angular packing-piece around the
tubular socket and clamping it by the lock-ut an angular or inclined adjustment of
the chin-board in any direction can be obtained.
I effect the vertical and radial adjustment of the chin-board by means of parallel
packing-pieces or washers inserted between the lock-nut and the upper clamp. The
radial adjustment can also be effected by the angular packing-piece.
When vertical and radial adjustments only are required the tubular socket may be
fixed vertically to the under side of the chin-board and a parallel packing-piece or
pieces substituted for the angular or wedge-shaped packing-piece..

A. A are the clamping-pieces and B is the right and left hand male screw con-
necting the said clamping-pieces and by which they are secured upon the edge of
the instrument. Each clamping-piece consists of a disc or plate a having
a plate a¹ and tubular socket projecting at right angles from one edge
thangof The inner five of the plate of each clamping piece is formed

page_text: In
recess a³ into which recesses the edges of the violin or viola fit when the clamp
is secured upon the instrument, the face a of the said plate and the inner side of
the tubular socket a² then buiting against the edge or ribs of the instrument.
The inner face of the disc a of each clamping-piece is also formed with a recéss a
to prevent any crushing of the edges of the instrument or damage thereto.
the sockets of the clamping-pieces A A' are formed respectively right and
left hand female screws to receive the right and left hand male screw B which
has a central boss provided with a hole for the insertion of a lever by which the
said screw can be operated so as to clamp the chin-holder upon the instrument or
remove it therefrom.
The top of the upper clamping-piece A carries a vertical screw a³ which screws
into a tubular socket. C jointed to the chin-board D so as to project from the
underside of the said chin-board and so as to move freely in every direction within
certain limits. In the drawing I have shown the said socket formed with a head e
which works freely in a countersunk socket E screwed into the lower end of a hole
formed in the chin-board. The said socket is countersunk on both upper and under sides
so as to allow the tubular socket to move freely in every direction. Around the
tubular socket is fitted a loose adjustable angular packing-piece F the lower face of
which is horizontal but its upper face is bevelled or inclined at the desired angle,
as shown in the drawing. The said packing-piece can be clamped against the under-
side of the chin-board D by means of the lock-nut G which screws on to the lower end
of the tubular socket C. The head e of the tubular socket C may have a pin or
projection on its edge, fitting into a groove or nick in the socket E as shown at c¹
figure 3, so as to prevent the said tubular socket from turning round in its socket E
when the lock-nut is being screwed upon it. The lock-nut G has a milled edge to
facilitate its operation and a hole for the insertion of a lever for tightening up. By
loosening the said lock-nut and revolving the angular packing-piece F the chin-board
can be set at an angle in any desired direction to suit the performer, when it is
again clamped up by the said lock-nut.
I do not confine myself to the above-described method of jointing the socket to
the chin-board as it may be jointed thereto in any other suitable manner which will
admit of its moving freely in every direction within the necessary limits for the
angular adjustment of the chin-board.
To effect the vertical and radial adjustment of the chin-board I insert washers or
packing-pieces H having parallel faces between the lock-nut G and the upper clamping-
piece A, the said washers being clamped between the upper clamp and lock-nut by
serewing the upper clamping-piece by its screw a' into the tubular socket C. These
packing-pieces H are made of various thicknesses so that the vertical or radial
adjustinent of the chin-board with relation to the clamp and instrument can be adjusted
to a nicety. The washers H may be formed with a central hole for the screw a³ or,
for convenience, they may be formed with a sloth (as shown in figure 4) extending to
the centre of each packing-piece so that by loosening the upper clamping-piece A
they can be slipped into position between the said upper clamp and lock-nut G, the
screw a entering the sloth and passing to the centre of the washer. By the inser-
tion of the requisite washers or packing-pieces H the chin-board can be raised to the
desired height above the instrument, and if, when the whole are clamped by screwing
up the upper clamping-piece, the chin-board has not the desired radial adjustment, it
can be obtained by the insertion of one or more very thin washers or packing-
pieces H.
When an angular or inclined adjustment of the chin-board is not desired, but
only vertical and radial adjustments, the packing-piece F may have its upper and
lower surfaces parallel. Or the tubular socket C may be fixed to the underside of
the chin-board at right angles thereto and the requisite vertical and radial adjustments
of the chin-board obtained by the insertion of washers or packing-pieces H between
the upper clamping-piece A and the chin-board, the whole being clamped together
by screwing the upper clamping-piece by its screw a into the socket C.
Also the lock-nut G may be dispensed with and the angular or parallel packing-

page_text: piece F cither alone, or with parallel packing-pieces H may be clamped between
the upper clamping-piece A and the chin-board D. The chin-board D may be of the
form shown or of other suitable shape.
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
First In an adjustable chin-holder for violins or violas, the combination of the
upper and lower clamping-pieces A. A' and right and left male screw B substantially
as herein set forth.
Second In an adjustable chin-holder for violins or violas, the combination of the
chin-board D, a tubular socket C freely jointed thereto, the angular packing-piece F
and lock-nut G substantially as herein set forth.
:
Third The combination of the chin-board D, tubular socket C freely jointed
thereto, the angular packing-piece F, lock-nut G, clamp with screw a" and one or
more parallel washers or packing-pieces H, substantially as herein set forth.
Fourth The combination of the chin-board D, a tubular socket C fixed thereto,
clamp with screw a and one or more parallel washers or packing-pieces clamped
between the said clamp and chin-board, substantially as herein set forth.
Fifth The combination of the chin-board D, tubular socket C freely jointed
thereto, angular packing-piece F, clamp with screw a³, and one or more packing-
pieces H substantially as herein set forth.
Sixth The combination of the chin-board D, tubular socket C freely jointed
thereto, angular packing-piece F and clamp with screw a³, substantially as herein set
forth.
