PROVISIONAL SPECIFICATION left by the said Josiah Horsfall at the
Office of the Commissioners of. Patents; with his Petition, on the 24th
April 1855.
I, JOSIAH HORSFALL, of Manchester, in the County of Lancaster, Joiner,
do hereby declare the nature of the said Invention for "MACHINERY FOR
MITREING MOULDED AND OTHER SASHES to be as follows:
My Invention consists of a horizontal block, in which the bar and other
parts of the sashes to be "operated upon are secured; also of a single angled
chisel, and also of a double angled chisel, and other chisels for the purposes
of scribing, bevelling, &c.; also in parts for holding the above chisels in their
respective positions, and peculiar arrangement of parts for giving motion to
the same.

by the said Josiah Horsfall in the Great Seal Patent Office on the
24th October 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSIAH
HORSFALL, of Manchester, in the County of Lancaster, Joiner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of April, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Josiah Horsfall, Her special license that I, the said Josiah Horsfall,
my executors, administrators, and assigns, or such others as I, the said Josiah
Horsfall, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "MACHINERY FOR MITREING MOULDED
AND OTHER SASHES," upon the condition (amongst others) that I, the said
Josiah Horsfall, by an instrument in writing under my hand and seal, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
. NOW KNOW YE, that I, the said Josiah Horsfall, do hereby declare the
nature of my said Invention, and in what manner the same is to 'be' per-
formed, to be particularly described and ascertained in and by the following
Specification thereof, reference being bad to the accompanying Drawing (that
is to say)-
The nature of my Invention consists in a combination of machinery for
mitreing sashes, by means whereof manual labour is economized. I have.in the
said Drawing given Figures for shewing how my Invention may be constructed,
similar parts in each of the views being marked with similar letters of
reference.
Figure 1 is a front elevation of the mitreing machine; Figure 2, a side eleva-
tion; and Figure 3, a plan in section through the line A, B, on Figure 1. a is
the foundation plate, to which is attached the frame b and standard C; to the
frame b is fixed the block d, in which the bars and other parts of sashes to be
operated upon are secured. The cutting tool, marked e, is fitted in the spindle f,
which is guided in the socket g, formed partly in the frame b and partly by

page_text: the lid h. The spindle f is brought down by means of the lever or treadle i,
to which is connected the lower end of the link j, the upper end being jointed
to the lever k, whose fulcrum is in the standard c; the outer end of the lever k
fits in a slot in the spindle f, which is raised up after it has been depressed
by the spring contained in the socket g. The depth of the cut is regulated
by the lock nuts f', which fit on a screw forming part of the spindle f. The
block d is furnished with a peg m, fitting in the mortice hole of the sash bar
to be operated upon. The mode of operation is as follows:-The attendant,
after placing a mortice hole of the morticed sash bar on the peg m, depresses
the lever or treadle i, thereby bringing down the four-edged cutting tool e on to
the sash bar, into which the requisite cuts are made on each side for the mitres;
as soon as the lever or treadle i is released, the spindle and cutting tool are
raised by the spring l, and the attendant moves the sash bar into the proper
position for the next cut. It is evident that by removing the cutting tool e,
other shaped tools may be substituted in its stead.
When the sunk bars are to be mitred, the peg m is pushed into the block d
and the peg n is brought forward; the sinking in the rabbetted part of the
sash bar is then put upon the peg n, and the tool e is brought down to cut
the requisite mitres as before.

block o is attached to the front of the block d.
on the block o, being guided to the proper position by the peg p; the cutting
tool is then brought down as before to bevel the ends of the said cross
sash bars..
Figure 5 represents a tool for cutting the mitres in sashes of large
dimensions. When this tool is used, the block d must be made to correspond
with the mould of the sash to be operated upon. This tool is formed of two
cutting blades, secured to a block by screws, as shewn in the Drawing. The
lower part of the block, marked d', is removed during the operation of mitreing
the meeting bars to allow for their extra width.
Figure 6 represents a tool for cutting the mitres or joinings of the bars of
rustic or mill sashes. This tool is made with one of the cutting blades attached
to the block and the other secured thereto by screws. When each side of a
bar has been operated upon by this tool, the portions of the bar are cut away
by the tool shewn at Figure 7. This tool is also put together in two pieces,
as shewn in the Drawing.
Having thus stated the nature of my Invention, and described the manner
of performing the same, I wish it to be understood that I do not limit myself
.

page_text: to the details herein set forth; as the same may be varied without departing
from the peculiar character of my Invention; and that what I claim is, the
combination of machinery for mitreing sashes and the tools shewn and
described for effecting the various operations.
In witness whereof, I, the said Josiah Horsfall, have hereunto set my
hand and seal, this Twenty-second day of October, in the year of our
Lord One thousand eight hundred and fifty-five."
