Year: 1875

page_text: LETTERS PATENT to Walter Herbert Avis, of Hastings, in the County
of Sussex, for the Invention of "AN IMPROVED MACHINE FOR MITREING,
TENON CUTTING, MORTISING, AND BLIND PUNCHING.”
Sealed the 12th November 1875, and dated the 19th May 1875.
PROVISIONAL SPECIFICATION left by the said Walter Herbert Avis
at the Office of the Commissioners of Patents, with his Petition,
on the 19th May 1875.
I, WALTER HERBERT AVIS, of Hastings, in the County of Sussex,
do hereby declare the nature of the said Invention for "AN IMPROVED
MACHINE FOR MITREING, TENON CUFTING, MORTISING, AND BLIND PUNCHING,” to
be as follows :-
My Invention relates to a combined mitreing, tenon cutting,
mortising, and blind punching machine, and it consists in so con-
structing a mitreing machine that it is adapted to perform the various
other operations mentioned.

page_text: According to my Invention the cutter carrier guides instead of being
fixed in one position as usual are made adjustable by being pivoted at
their lower end to the base plate of the machine, and are supported at
their upper end by fixed quadrants rising from the base plate. The
guides are firmly fixed at any desired position along these quadrants 5
according to the angle or inclination at which the cutter is to work by
binding screws and eccentric clamps, and the quadrants may be
graduated to facilitate the adjustment of the tool at any desired
angle.
For mortising and for punching the holes in the laths of Venetian 1
blinds the cutter guides are fixed vortically, and the mitreing cutter
is replaced by a mortising tool or by a punch, as the case may be.
For tenon cutting likewise a suitable cutter is employed, the cutter carrier
boing adapted to receive tools or cutters of different kinds.
Stops or clamps are provided on the guides to hold down the material 1
when masticine

the lever, and at the other to a collar » so fixed on rod h that said rod is
free to turn within collar n, although the latter cannot move along the
rod; o is a handle jointed to a collar p fitted on a squared part of rod h,
whereby the said rod may be readily turned to reverse tho chisols or
5
cutters. The handle o has a projecting part o¹ which drops into one of
four notches in collar n to lock the tool rigidly in the direction in which
it may bo turned. The base a has raised sides to form guides for the
wood to be operated on as it is passed along bed a between the
quardrants b, or it may be passed across the front upon a bed r supported 1
by a strong centre pin a fixed to base a, and adjusted at any desired
angle by means of the wing nut & in semicircular slot u; v are stops or
clamps fixed adjustably by wing nuts to frame c to hold down
the work when mortising; to, mortise chisel shown fixed in socket in
end of rod h, where it is retained by spring catch x, set screw, or other 1

page_text: 2nd. I claim the device as described for turning the tool carrier
and locking it rigidly in the direction in which it may be turned.
3rd. The employment of a round rod or tool carrier in a combined
mortising and mitreing machine as and for the purpose specified.
4th. Fixing the mitreing tool in such a manner that the back of the
knife works quite clear of the mitre, and does not rub against the same
as in ordinary as described.
In witness whereof, I, the said Walter Herbert Avis, have hereunto
set my hand and seal, this Twenty-seventh day of November, in
the year of our Lord One thousand eight hundred and seventy-
five.
