PROVISIONAL SPECIFICATION.
A New or Improved Machine for Cutting, Shaping, and Boring
Violin and like Pegs, with Reamer for Clearing Out the Holes
in Peg Box of Instrument to a Proper Taper.
I WILLIAM NEEDHAM of 34 Albert Street, Crewe in the County of Cheshire,
Professor of Music, do hereby declare the nature of this invention to be as
follows:
-
It is well known that wooden pegs which hold the strings of violins and like
instruments are supplied by the trade, but they rarely fit the instrument for which
they are intended. I have therefore designed a small machine for cutting shaping
and boring such pegs.
According to this invention in a small cylinder I fit a knife or cutter capable of
adjustment by means of screws, so that when the round part of the peg is inserted
in the cylinder, pressed forward and turned round, the aforesaid knife will cut the
peg to the proper shape and size.
also provide a moveable bed, capable of adjustment by means of screws, so
that the round part of the peg may be forced against the knife of cutter.
The boring tool is screwed through the cylinder so that it will bore the hole in
the peg at the desired place.
Such tool may be then withdrawn, by turning it to the opposite end it is again
screwed through cylinder and cuts the peg off the required length rounding the
end of peg at the same time.
The reamer part of the machine is in the form of a violin peg with a knife or
cutter running up one side and is used to insert in the holes in which the pegs have
to fit, is turned round and reamers the holes to required size.

COMPLETE SPECIFICATION.
A New or Improved Machine_for Cutting, Shaping, and Boring
Violin and like Pegs, with Reamer for Clearing Out the Holes
in Peg Box of Instrument to a Proper Taper.
I, WILLIAM NEEDHAM of 34 Albert Street, Crewe in the County of Cheshire,
Professor of Music, 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 :-
It is well known that wooden pegs which hold the strings of violins and like
instruments are supplied by the trade, but they rarely fit the instruments for which
they are intended. I have therefore designed a small machine for cutting, shaping
and boring such pegs.
In order that my said invention may be fully understood, I will proceed to
describe the same with reference to the accompanying sheet of drawings in
which
Fig. 1 shews elevation of a machine or tool for cutting, shaping and boring the
wooden pegs which hold the strings of violins and like instruments;

page_text: Fig. 2 shews section through line A B Fig. 1;
Fig. 3 shews the reamer;
Fig. 4 the cutter detached ;
Fig. 5 the borer detached.
Fig. 6 is a section through line C D of Fig. 3.
The same letters denote the same parts in all views.
a shews the body of the machine or tool, b adjustable bed regulated by means of
the screws c, c screwing through the small cylindrical portions or lugs d, d;
e shews the cutter, adjusted by means of the screws f,f; 9,9 are small flanges
fixed on the heads of screws f, f, which take into the slots h, h in the cutter e so
as to actuate this latter as hereafter described; i is another screw passing through
a slot in the cutter e so as to fix the cutter e in the desired position; 7 is a
small cutter formed on the main cutter e, for cutting off and shaping the ends of
the pegs; m is a cylindrical projection, formed on the body a, through which the
screwed portion n of the boring tool o is screwed; p is a fly-nut which fits on to
either end of the boring tool o, which latter are squared for this purpose. The
boring tool o is made double, giving two different sized drills, so as to give two
different sized holes. The larger drill is shewn dotted in Fig. 5.
The reamer
shewn at Fig. 3 and in section at Fig. 6, is made taper in its length, and has a
cutter formed thereon.
The action is as follows:
The peg "blank" is inserted in the body a of the machine and the bed 6 forced
down by means of the screws c, c until the said peg is forced against the cutter e
which is inclined by means of the screws f, f to form the required taper on the peg.
The peg is then turned round so as to cut it to the required size, and when the end
comes against the small cutter 1, this cutter will cut off the peg to the required
length. The screwed portion n of the boring tool o is then screwed into the
projection m on the body a, so as to bore a hole in the peg at the desired place for
the string to be attached to. The holes in the violin or other instrument into
which the pegs are to be fitted, are reamed out to the required size necessary for
the pegs to fit in, by means of the reamer shewn at Fig. 3.1
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. In a machine or tool for cutting, shaping and boring violin and like pegs, the
body a, adjustable bed b, cutter e, borer o, all arranged substantially as and for the
purposes set forth.
2. Machines or tools for cutting shaping and boring violin and like pegs,
substantially as set forth.
