PROVISIONAL SPECIFICATION.
Improved Cutting Tool for Producing Rectangular Holes or Openings
in Metal, Wood, or the like.
We, WILLIAM HENRY MURTON and WILLIAM SAGAR VARLEY, both of Anchor
Iron Works, Keighley, in the County of York, Machine Makers, and ELI
MURTON, of the same place, Mechanic, do hereby declare the nature of this
invention to be as follows, that is to say:-
:-
66
This invention relates to an improved cutting tool for producing rectangular
holes or openings in metal, wood or the like, such tools being commonly known
as square drifts" and our said invention relates more particularly to those
used in the formation of the openings for the reception of the shafts or arbors
of rollers for wringing, mangling and like machines and consists in so form-
ing or constructing said tools or drifts that they are more cheaply produced
and yet will perform their functions more efficiently than those as heretofore
constructed.
In carrying our invention into effect we make use of a bar or rod of metal
rectangular (or if for the purpose of forming the openings through wooden
rollers then square) in cross section and at its angles we form a series of indents
which produce projections or teeth. These said indents we preferably form by
mounting said bar or rod in an ordinary turning lathe, and thereby with a
suitable tool or tools, cutting one or more grooves or spirals of the required
shape in cross section so as to leave a series of teeth of the formation desired
and also provide space for the clearance of the wood or metal removed during
the cutting operations. As a further means of clearance for the substance or
material being thus removed we form longitudinal furrows or grooves to inter-
vene between the several series of teeth.
We may, if desired, form a handle part or shank upon the cutting tool to
enable its use generally, however, when it is intended to be employed in the
formation of the holes or openings for the square shafts or arbors of wringing
and mangling machines' rollers we preferably construct it to be only of sufficient
length to perform its cutting operations and to be fed through the roller by
means of the shaft or arbor which is forced into position therein during the
actual cutting operations of the cutter bar, the latter being free when having
passed thus through. We also preferably form a protruberance at the front of
said tool for guiding it within the circular opening formed in said roller through
which it is being forced to produce the opening of desired formation, the ex-
tremity of this said protruberance being hollowed or having a cavity formed
in it so as to enable it to remove and receive any slight obstructions that may
be in its path through the roller's opening, while the opposite end of said tool
which is for contact with the shaft or arbor used for forcing it as described is
also suitably formed to receive the end of said arbor or shaft.

We, WILLIAM HENRY MURTON and WILLIAM SAGAR VARLEY, both of Anchor
Iron Works, Keighley, in the County of York, Machine Makers, and ELI
MURTON, of the same place, Mechanic, 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, that is to say:—
66
This invention relates to an improved cutting tool for producing rectangular
holes or openings in metal, wood or the like, such tools being commonly known
ay square drifts," and our said invention relates more particularly to those
used in the formation of the openings for the reception of the shafts or arbors
or rollers for wringing and mangling and like machines and consists in so form-
ing or constructing said tools or drifts that they are more cheaply produced
and yet will perform their functions more efficiently than those as heretofore
constructed.
In the accompanying sheets of drawings, which are illustrative of our said
invention:-
Figure 1 is a side elevation of our improved tool.
Figure 2 is an end view of said tool as seen in the direction of the arrow x.
Figure 3 is a perspective view thereof.
Figure 4 is a side elevation of a modified form of our improved cutting tool.
Figure 5 is an end view thereof as seen in the direction of the arrow y.
Figure 6 is an end elevation of a portion of a machine for use in inserting
the shafts of wringing, mangling and like machines' rollers.
Figure 7 is a plan or parts illustrated by Figure 6.
Similar letters and figures of reference indicate similar parts throughout the
several views.
In carrying our invention into effect we make use of a bar or rod of metal a
rectangular (or if for the purpose of forming the openings through wooden rollers
than square) in cross section and at its angles 1, 2, 3, 4 we form a series of
indents b which produce projections or teeth c. These indents b we preferably
form by mounting said bar or rod a in an ordinary turning lathe, and thereby
with a suitable tool or tools, cutting one or more grooves or spirals of the
required shape in cross section so as to leave a series of teeth c of the formation
desired and also provide the spaces b for the clearance of the wood or metal
removed during the cutting operations. As a further means of clearance for
the substance or material being thus removed we form longitudinal furrows
or grooves e to intervene between the several series of teeth c.
We may, if desired, form a handle part or shank f of suitable length upon
the cutting tool to enable its use generally, however, when it is intended to
he employed in the formation of the holes or openings for the square shafts o
arbors g of wringing and mangling machines' rollers we preferably construct it
to be only of sufficient length to perform its cutting operations (see Figs. 1 and 2]
and to be fed through the roller h by means of the shaft or arbor g which is
forced into position therein during the actual eutting operations of the cutter
bar a the latter being free when having passed thus through.
We also preferably form a protruberance k at the leading end of said tool
for guiding it within the circular opening formed in said roller h through which
it is being forced to produce the opening of the desired formation, the extremity
of this said protruberance being hollowed or having a cavity k (as shown in

page_text: dotted lines Fig. 1) formed in it so as to enable it to remove and receive any
slight obstructions that may be in its path through the roller's opening while
the opposite end a¹ of said tool which is for contact with the shaft or arbor
used for forcing it as described is also suitably formed to receive the end g¹
of said arbor or shaft g.
A convenient form of apparatus for operating the cutter bar a when forming
holes or openings in the rollers h of wringing and mangling machines for the
reception of their shafts 9 is illustrated by Figures 6 and 7 of the drawings.
The roller h in which it is desired to place the shaft g is mounted on blocks
or supports m on the bed n of the machine. The protruberance is inserted in
the circular opening which extends through the centre of the roller, and the
shaft or arbor placed between it and the movable block o, which is moved or fed
by means of the screw shafts ? operated from the driving pulleys q, q¹ through
the gearing wheels r, r¹, r². By this means the cutter is passed entirely through
the roller and falls on to the bed n or into a suitable receptacle mounted to
receive it, while the shaft or arbor g will have been moved to its requisite posi-
tion within the roller h. Another roller may now be mounted at the opposite
side of the machine and an opening formed therethrough in a similar manner
to that above described the movement of the block o being attained by reversing
the direction of the screwed shafts p.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. The improved "drift" or cutting tool for producing rectangular openings
in metal, wood or the like, substantially as herein specified.
2. An improved tool for use in producing openings for the shafts or arbors
of rollers of wringing, mangling and like machines, the same being constructed
and arranged to operate in the manner and for the purpose substantially as
herein specified.
