Improvements in Joiners' Ploughs.
I JACOB LALEY POPE, of 21, Headlam Street, Stockton-on-Tees, Durham,
Joiner and Carpenter, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in joiners' ploughs, and has for its object to
so construct such ploughs, that they will cut clean grooves in the wood operated
upon, without jagging or splitting same, and without breaking out or splitting knots
or the like further objects being to obtain a plough that will readily cut or groove
end wise through the grain of the wood, without the aid of a saw or other extraneous
means, and one that will be capable of being set or adjusted so as to cut desired
depth of groove, in a readier and truer manner than heretofore.
any
According to my invention I provide a vertical slot or box in the forward portion
of the tool, designed to receive a blade or cutter having its lower or cutting end so
fashioned that two scores or sides of an intended groove of any desired depth will
be made by the edges or sides of such blade or cutter, for the purpose of enabling
the rear cutter or centre-iron to cut a clean groove in the material.
The said front blade or cutter is recessed or grooved in its face and back, to
prevent lateral displacement of such blade or cutter, and is adjusted and held in
place in the vertical slot aforesaid, by means of a suitable screw working
horizontally in the front part of the tool, and abutting against the said front blade
or cutter.
I also provide side fences, in front and to the rear of the centre-iron, which side
fences are fixed in position by means of counter-sunk screws; and studs, which latter
enter holes formed for the purpose in the blade of the plough and prevents undue
strain upon the screws and any movement of the said side fences. These side fences
are formed of varying thicknesses for the purpose of bringing the front cutter, the
centre-iron, and such fences into a parallel line. The centre-iron is regulated by a
suitable screw regulating device, and is formed with a slot in the side in lieu of a
nib as formerly.

COMPLETE SPECIFICATION.
Improvements in Joiners' Ploughs.
I JACOB LALEY POPE of 21 Headlam Street Stockton-on-Tees Gentleman 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 :-
'
My invention relates to improvements in joiners' ploughs and has for its object to
so construct such ploughs that they will cut clean grooves in the wood operated
upon without jagging or splitting knots or the like, further objects being to obtain
a plough that will readily cut or groove end wise through the grain of the wood

page_text: without the aid of a saw or other extraneous means, and one that will be capable of
being set or adjusted to cut any desired depth of groove in a steadier and truer
manner than heretofore.
In the accompanying drawings Figure 1 is side elevation of joiners plough
constructed according to my invention, Figures 2 and 3 detail views Figure 4
section on line x Figure 1.
According to my invention I provide a vertical slot in the forward portion of the
tool, designed to receive a blade or cutter a having its lower or cutting end b so
fashioned that two scores or sides of an intended groove of desired depth will be
made by the edges or sides c. c. (Figure 2) of such blade or cutter for the purpose
of enabling the rear cutter or centre iron d to cut a clean groove in the material.
The said front blade or cutter a is recessed or grooved as at e (Fig. 2) in its face
& back to prevent lateral displacement of such blade or cutter.
which
I also provide side fences f (Figs. 1 & 4) to the front and to the rear of the centre'
iron which side fences f are fixed in position by means of screws or studs
latter enter holes formed for the purpose in the blade of the plough. The said
side fences are of such thickness as to bring the front cutter & the centre iron or
cutter a & the said side fences f. f. into line with one another.
To afford an increased bearing surface for the tool upon the work the plate kis
provided capable of being raised or lowered by screw l m. m are openings through
the body of the tool to receive arms or pieces carrying the guide ordinarily
employed therewith, the centre iron is formed with a slot or recess i (Fig. 3) in the
side in lieu of a nib formerly used so that it may be more readily passed through
the opening in the body of the tool. The front cutter a. is held in place by screw p.
so that it is easily adjusted to any depth of groove desired.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
CLAIMS.
1. In a joiners plough the front cutter a shewn in Fig. 2 arranged as and for the
purpose herein set forth.
2. In a joiners plough the side fences f. f. arranged as and for the purpose herein
set forth.
3. The improvements in joiners ploughs substantially as herein set forth and
described & illustrated by the accompanying drawings.
Dated this 10th day of January 1895.
