page_text: PROVISIONAL SPECIFICATION.
I JAMES SWINDELLS of Chatham Street Stockport in the County of Chester
Staircase Builder do hereby declare the nature of the said invention for
" IMPROVEMENTS IN MACHINERY FOR TRENCHING OR SLOTTING WOOD TRANS-
VERSELY OR DIAGONALLY" to be as follows: and for convenience and simplicity
have divided the description thereof into 4 parts.
Part 1-Consists of the Stand upon which parts 2 and 3 hereafter described are
fixed, and is formed by an iron frame upon 4 legs of convenient height, the 2 back
legs having small wheels or casters for easy means of removal. The top of the
frame is about 3 feet 9 inches long by 6 inches and a half wide, with a rebated
slot down the centre of same, longitudinally wherein is placed a loose nut about
4 inches long, with vertical screw about 6 inches long, and about three-quarters
of an inch thick, such screw having at its bottom end, a fly-wheel of about
14 inches diameter and at the top end and above the Stand top an iron plate of
about 14 inches by 8 inches so secured to the screw as to enable it to be swung
round horizontally-From the foregoing it will be seen that the nut with the
screw wheel and plate may be moved about the slot in the top of the frame,
thus enabling it to be placed in any part of the said slot.
Part 2-Consists of the brackets, slide and fence by which the size and shape
of the slot required to be made in the wood is regulated-The brackets are 4 in
number 2 of which are fixed on the front of the Stand about 2 and a half inches
apart, 4 inches high and bent over at right angles to the right and left, the top of
each bracket having a slot to receive a bolt; the space between the 2 brackets now
being described being opposite to slot in Stand top previously described in Part 1
the other 2 brackets being fixed in like manner about 8 inches from the back of
the Stand-Upon the brackets are placed 2 movable guiders spanning from the
front ones to the back ones and are formed from 2 inch T iron holed at each end in
such manner as to correspond with slots in top end of brackets to which they are
secured by 4 half-inch bolts with fly-nuts at such distance apart as may be required-
In the space between the top of the frame and the guiders, is placed a fence, about
2 feet long which may be set to any angle required and made fast by means of a
bolt passing through the lower part of the fence and the slot in the Stand top-

page_text: The face of the fence is placed towards the front end of the machine and the
position of the swivel plate described in part 1 is ruled by the position of this
fence, one side or one end of the said plate being placed against the front of the
fence.
Part 3 Consists of a Standard carrying a balanced lever with Catch and Claw-
attachment also 2 small guide pulleys.
The Standard is formed of iron about 3 inches by inch and is firmly fixed to
the top of the Stand, one side thereof being facible to the right hand side of the
slot in stand top and about 12 inches above the same, curving over about 5 inches
towards the front of the Stand-Through the top end of the Standard is passed a
Stud on one end of which is fixed the lever extending to the front end of the
frame with a handle thereto convenient to the Operater-On the other end of
the lever, beyond the Stud, is placed a weight to balance the said lever-On the
opposite end of the Stud is fixed a small Crank at right Angle to the lever, within
about an inch and a half of the guiders described in part 2-On the bottom end
of the Crank is hinged a claw-catch, which is intended to take hold of Sawtooth
rack described hereafter in part 4-Near the bottom of the Standard and on the
same side as the Crank is fixed 2 friction pulleys in such position as to guide
part 4.
Part 4-Consists of a Plane with 2 Spring side Cutters, plane-bit and a Saw-
tooth rack.
The Plane is formed of iron and is about 12 inches long by 2 inches wide
having a handle at the end next to the Operater, the plane-bit being fixed to
proper Angle in same by means of a wedge, the 2 spring side cutters being
secured by set screws in such a manner as to be fixed any distance apart up to
21/2 inches-As regards their distance apart they are compressible so as to make a
slot in the wood out of parallel when the guiders referred to in part 2 are so set
On the opposite end of the said handle and in line therewith is attached a Sawtooth
rack about 2 feet long, having the cutting edge of the teeth towards the plane, and
when the said plane is placed in position the rack above described passes between
the friction pulleys described in part 3 and is so kept in its proper position, the
plane resting on the guiders described in part 2 with the spring side cutters and
plane-bit between the said guiders projecting below the bottom thereof-sufficiently
to make the Slot in wood of the required depth, the clawcatch is let down and
operates with the sawtooth rack the Operater then taking hold of the lever with
one hand, and the handle of the plane with the other, lifts the said lever, thus
causing the clawcatch to move along the back of the sawtooth rack in a direction
towards the front end of the machine and upon the lever being brought down, the
reverse motion takes place, the clawcatch taking along with it the rack and plane,
at the same time the spring side cutters and plane-bit are passing through the
wood which is placed in the machine transversely or diagonally on the plate
described in part 1 with one edge against the fence described in part 2, and by
means of screw and fly-wheel described in part 1 it is raised and secured tightly
to the underside of the guiders-The required slot in the wood being formed by
the means described, the lever is then let go and by the action of the balance weight
is raised, the plane is then withdrawn from the guiders and placed in its original
position at the front end of the frame.

page_text: I JAMES SWINDELLS of Chatham Street Stockport in the County of Chester
Staircase Builder do hereby declare the nature of my invention for IMPROVE-
MENTS IN MACHINERY FOR TRENCHING OR SLOTTING WOOD TRANSVERSELY OR
DIAGONALLY and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement: and for convenience
and simplicity have divided the description thereof into 4 parts:-
Part 1. Consists of the Stand upon which parts 2 and 3 hereafter described are
fixed and is formed by an Iron frame upon 4 legs of convenient height. The top
of the frame is about 3 feet 9 inches long by 61/2 inches wide with a rebeted slot
down the centre of same longitudinally, wherein is placed a loose Nut about
4 inches long with vertical Screw about 4 inches long and inch thick, such
Screw having at its bottom end a fly-wheel of about 14 inches diameter and at the
top and above the Stand top a circular iron plate of about 6 inches in diameter,
so secured to the screw, as to enable it to be swung round horizontally-From the
foregoing it will be seen that the Nut with Screw, wheel and plate may be moved
about the slot in the top of the frame thus enabling it to be placed in any part of
the said slot.
Part 2 Consists of the Brackets slide and fence by which the size and shape of
the Slot required to be made is regulated. The Brackets are formed as hereafter
described and shewn in the Drawings referred to in such description-Upon the
brackets are placed 2 movable Guiders spanning from the bracket placed upon the
front of the Stand to one placed at the back thereof and are formed from 1 inch
and a half T iron holed at each end, in such manner as to correspond with slots.
in brackets, to which they are secured by 4 half inch bolts with nuts, at such:
distance apart as may be required, and so regulate the width and shape of the
slot In the space between the top of the frame and the Guiders is placed a fence
about 2 feet long which may be set to any Angle required and made fast by means
of a bolt passing through the lower part of the fence and the slot in the Stand
top. The face of the fence is placed towards the front end of the Machine and
the position of the swivel plate described in part 1 is ruled by the position of
this fence.
Part 3 Consists of 2 Standards carrying a balanced lever with clawcatch
attachment also 2 small Guide pullies.
The Standards are hereafter particularly described and shewn in the Drawings
referred to in such description-Through the top end of the Standards is passed
a Stud on one end of which is fixed the lever extending to the front end of the
frame with a handle thereto convenient to the Operater-On the other end of the.
lever beyond the Stud is placed a weight to balance the said lever-On the portion
of the Stud between the Standards is fixed a small crank at right Angle to the
lever On the bottom end of the Crank is binged a claw-catch which is intended
to take hold of sawtooth-rack described hereafter in part 4-Near the bottom of
the Standards are fixed 2 pullies in such position as to guide part 4.
Part 4 Consists of a Plane with 2 Spring side cutters, plane-bit and a Sawtooth-.
rack The plane is formed of iron and is about 12 inches long, having a handle
at the end next to the Operater, the plane-bit being fixed in same by means of a

page_text: setscrew, the 2 Spring side Cutters being secured by setscrews in such a manner
as to be fixed any distance apart up to 2%, inches-As regards their distance apart
they are compressible so as to make a Slot in the Wood out of parallel, when the
guiders referred to in part 2 are so set-On the opposite end of the said handle,
and in line therewith, is attached a Sawtooth-rack about 2 feet long having the
cutting edge of the teeth towards the plane and when the said plane is placed in
position, the rack above described passes between the friction pullies described in
part 3, and is so kept in its proper position, the plane resting on the Guiders
described in part 2 with the spring side cutters and plane-bit between the said
guiders, projecting below the bottom thereof, sufficiently to make the slot in wood
of the required depth, the clawcatch described in part 3 is let down and operates
with the Sawtooth-rack, the Operater then taking hold of the lever with one hand,
and the handle of the plane with the other, lifts the said lever thus causing the
clawcatch to move along the back of the Sawtooth-rack in a direction towards
the front end of the Machine, and upon the lever being brought down, the reverse
motion takes place, the clawcatch taking along with it the rack and plane, at the
same time the Spring Side Cutters are passing through the wood which is placed
in the Machine transversely or diagonally on the plate described in part 1, with
one edge against the fence described in part 2, and by means of screw and fly
wheel described in part 1 it is raised and secured tightly to the underside of the
guiders The required Slot in the Wood being formed by the means described;
the lever is then let go, and by the action of the balance weight is raised, the plane
is then withdrawn from the guiders and placed in its original position at the front
end of the frame.
And in order that the said Invention may be more clearly understood and
readily carried into effect I will proceed, aided by the accompanying Sheet of
Drawings (which are quarter full size) to illustrate the same.
Fig. 1 is a plan, Fig. 2 a side Elevation partly sectional, and Fig. 3 a transverse
section, partly Elevation, of a Machine according to my invention-In these
Drawings the same reference letters are used to mark the same or like parts
wherever they are repeated-The Stand before described is marked A and the
rebeted Slot is shewn by dotted lines on side elevation (Fig. 2) but more clearly
on transverse section (Fig. 3) The loose nut, screw and fly-wheel are marked B
and shewn on Figs 2 and 3.
The Bracket C is formed of round iron, with a slotted plate D on its top, both
being firmly fixed to the top of Stand A by a bolt. The Bracket E is a casting
forming part of Standards F hereafter described-The Guiders are marked G and
fixed upon the brackets as before described and shewn upon the Drawings The
fence before referred to is marked H-The Standards F are formed in one Casting,
and firmly bolted to the top of the Stand A in the position and of the shape as
shewn in the Drawings A Stud I is passed through the top end of the
Standards F-The Lever J is firmly fixed to Stud I having a balance J¹ at one
end, and a handle J' at the other-A small Crank K is firmly fixed to Stud I
between Standards F and carries the Clawcatch L-As will be seen from the
Drawings the clawcatch L may be propelled by the Lever J into contact with
friction pulley M thus causing the clawcatch L to rebound, and become released,
enabling the Operater to withdraw the Sawtooth-rack O-Near bottom of and
between Standards F, 2 friction pulleys M and N are fixed, the pulley M. being
grooved to receive Sawtooth-rack O-The Plane P carries a fence Q, the latter
regulating the depth of Slot, also the Spring Side Cutters R and plane-bit S in
the position and as shewn in the Drawings. At the end of plane P beyond plane-
bit S is handle T and on the other end of plane P is attached Sawtooth-rack O
herein before described in Part 4.
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

page_text: what I claim is the Arrangement and Combination of parts Constituting the
Machine substantially as hereinbefore described and illustrated by the accom-
panying Drawings, the Novelty whereof Consists in the absolute originality of
the Machine generally for the purpose of trenching or slotting Wood.
