BENJAMIN BANKS of Lees Yard Meadow Lane Leeds Machine Maker and
JOHN ARMATAGE of 60 Salisbury Road Armley Leeds Joiner and GEORGE
ARMATAGE of Central Buildings Town Street Armley Leeds Joiner all in
the County of York do hereby declare the nature of this invention to be as
follows:-
We first make a base or bed of wood or iron having a level surface and on one
side we fit a fence or raised edge and on the other which can be either straight or
curved is fit a grove and all flush with the surface of the base or bed. Into these
groves we fit a stud or bolt with the head larger than the grove and the head of
which passes under the groved plate to this stud or bolt we fit a right angled
bracket or pillar having a grove on and through its vertical face on the top of this
grove the pillar or bracket forms itself into a collar through which collar we pass
a screwed stud having on its top end a hand wheel for turning the bottom or
screwed part which passes through a screwed nut which fitts into the groove of the
right angled bracket the nut haveing a stud formed on one of its faces which
projects beyond the vertical side of the right angled bracket on the other or raised
edge of base or bed is fitted a perpendicular screwed stud haveing a flange on
its bottom end with which to secure it to the base or bed the top end is screwed a
suiteable distance down on this is fitted a socket screwed inside, through which
passes the screw. On the top end of this socket is fitted a hand wheel for turning
it round on the screwed stud and raiseing and lowering it. We now fitt on to this
collar a cross beam or carrier beam which we will call cross beam. Through two
horozontal jaws at its near end. The other end of cross beam is fitted on to nut
that is fitted into the groove of the right angled bracket. Thus by turning the
hand wheel at each end the cross beam can be raised and lowered parrallel to the
base or bed and turned at any angle to the raised fence edge by passing along.
the curved or stright grooves in the base. The right angled bracket and the screwed
stud and socket forming the axis on which the cross beam turns. Between the
horozontal jaws ou end of cross beam is fitted the end of a lever the socket forming
the pin on which it moves.
Into the V or square grooves on the vertical face of the cross beam and passing
horozontally along it is a slide or carrier which for describeing we will call carrier
haveing a square or raised groove at one end, curved, at its other end, is formed a
pair of jaws into which fitts a link the other end of link fitts on to the lever that.
is fitted into the horozontal jaws on cross beam end, so that as the lever is moved
backward and forward the carrier by the link is moved at the same time. Thus:
the cross beam can be raised and lowered moved backward an forward as desired
for trenching cutting panels shouldering, tennoning scribeing & mitering.
When power is used we fitt a crank arm on to a pin on the carrier which works.
on a stud on a face plate of suiteable diameter haveing a groove across its face for .
regulateing the length of stroke.
The tool holder is formed by a plate that is fitted to the vertical side of slide
or carrier by a pin at one end the other end working in the groove at end of slider

page_text: or carrier. On the front or vertical side of tool holder we form grooves and
suiteable flanges for holding the tools and an incline for holding trenching iron
which also answers the purpose of tennoning iron.
On to the vertical side of plate we fitt a curved shoe for regulateing the depth
of cut and thickness of cut the end of purpendicular plate forming the stop for
depth of cut.
It will be obvious that the alterations of the cutters for various purposes is only
nescessary.
To the top side of the raised edge of the base or bed is fitted grooves into
these grooves is fitted a perpendicular bolt the head larger than the groove. On
the top of these bolts and over them is fitted a pillar haveing a flange on its bottom
and top end, the bottom flange resting on grooves and fence the top haveing a
grooved arm of suitable length resting on its face and parrallel to the base or bed
the vertical bolt passing through it, the grooved arm and vertical bracket being
thus secured in any position by the nut and washer on vertical bolt. To the end
of grooved arm is fitted or formed a vertical collar through which passes a vertical
spindle haveing a socket formed at its bottom end through which is fitted the
boreing bits the top end of the spindle is formed into a crank for turning the bits
and boring the holes at any desired position thus the work is bored trenched, and
set out all at one operation.
We also fitt to the guides or grooved plates markers or setters for setting out at
the required distances work to be done by the cutters thus forming it into setting
out machine for all the various works for which it can be used.

An improved Machine for Trenching, Panel Cutting, Shouldering,
Tenoning, and Scribing Wood by Hand or Power.
We, BENJAMIN BANKS, of Lees Yard, Meadow Lane, Leeds, Machine Maker,
JOHN ARMATAGE, of 60 Salisbury Road, Armley, Leeds, Joiner, and GEORGE
ARMATAGE, of Central Buildings, Town Street, Armley, Leeds, Joiner, all in the
County of York, 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:-
-
The object of our invention, is to construct apparatus whereby trenching, panel
cutting, shouldering, tenoning, scribing and like work, may be speedily and
efficiently performed, and this without the employment of expensive or complicated
machinery.
In order that our invention may be clearly understood we will proceed to
describe same with reference to the accompanying drawings, in which similar
letters refer to like parts in all the figures.
Fig. 1 shows a plan of an apparatus constructed according to our invention,
and Fig. 2 is a sectional side elevation of same.
Before proceeding with the description of the apparatus, we wish to state that
we prepared the Provisional Specification without the assistance of a competent
adviser, so we take this opportunity when filing the Complete Specification, to
correct the errors in description, punctuation, and orthography, occurring in the
said Provisional Specification.
According to our invention we employ a base or bed A having grooves B and C
running the full length of the said bed, and the said grooves are provided with

page_text: plates B and C which serve the double purpose of acting as raised edges to the
base A and making the grooves B and C of 1 section. D is a perpendicular
screwed stud which is securely fixed to the base A, and on this stud D a screwed
socket F is provided having a hand wheel E on same for the purpose of adjusting
the socket F up or down. G is a carrier beam which is fulcrumed on the
socket F, and the farther end of the said carrier beam G is adjustably held by a
right angle bracket H which is provided with a screw and hand wheel J for the
purpose of adjusting the carrier. beam G up or down in conjunction with the hand
wheel E. His a lock bolt for the purpose of clamping the bracket H to the
required position on the plates C¹. K is a groove on the face of the carrier
beain G, and L is a carrier which slides in the groove K, and a link M is
fulcrumed to the carrier L at M¹, the opposite end of the said link being connected
to a lever N which is fulcrumed to the socket F before described. P is a tool
holder being fulcrumed to the carrier L at P1, and the said tool holder P is
provided with a projecting portion P which works in a slot provided for the
purpose in the carrier L. Tools Rand S are attached to the tool holder P for the
purpose of cutting the sides of the trench or other recess to be made, and between
these tools R and S a gauge piece R' is mounted.being also attached to the tool
holder P. T is a trenching iron for making the cut and the said iron is adjustably
mounted on the incline T₁, and a curved shoe T2 is provided on the tool holder P.
for the purpose of regulating the depth of cut to be made, or the desired adjust-
ment may be effected by the set screw T³. A handle P³ is attached to the tool
holder P for the purpose of turning the said holder on its fulcrum P' thereby
moving the tools away from the work at any desired time. U is a boring
apparatus which is adjustable along the plates B, and the said boring apparatus is
provided with a grooved arm U' for adjusting the boring centre U to the required
position for boring centre holes. V is a clamping apparatus for clamping the work
to the edge of the plate B', a screw arrangement V₁ being provided for giving the
desired adjustment. W is a clamp which is connected to the carrier beam for the
purpose of clamping the work in the desired position, a clamping screw adjust-
ment W' being provided for adjusting the said cramp, and X is a gauge plate
which may be fixed in any suitable position on the bed A by means of screw
bolts Xmounted in the grooves X2. Adjustable stops Y, Y are mounted .in
suitable positions on the carrier beam G for the purpose of regulating the length
of stroke of the carrier L. Z is a scribing or undercutting tool fitted to the
vertically and horizontally sliding carrier Z. Suitable markers may be fitted in
the grooves B and C for the purpose of setting out the work to be done by the
cutting tools.
In employing the above described machine for tenoning, the beam G is set at
right angles to the bed A, as shewn in the drawings, when the work is placed on
the bed A up to the gauge plate X and against the edge of the plate B¹, after
which it is clamped in position by the clamp V. The beam G is now adjusted in
height by means of the hand wheels E and J, the tools or parts connected therewith
being set to suit the class of work and depth of cut to be made, and the clamp W
is screwed down onto the work. By actuating the hand lever N an oscillating to
and fro movement is given to the carrier L, thereby moving the tool holder P
with the tools attached to same backwards and forwards over the work and causing
the said tools to take a deeper cut at each stroke until the required depth of cut
has been reached, when the shoe T2 prevents the cut descending further. When
the machine is employed for trenching, or cutting at an angle as in the case of
"staircase strings," the beam G is turned on its fulcrum F and set to the angle of
the cut to be produced, in which position it is firmly held by the bracket H.
material to be operated upon is clamped down upon the bed A in a similar manner
to that above described, when the corner of the angle is first bored by the boring
apparatus U, after which the angular cut is produced by actuating the sliding
carrier L with its tool holder and tools, through the medium of the hand lever N
and connecting link M. When once the position of the boring tool U and angle
The

page_text: of cut is obtained, the cutting operation can be rapidly repeated, as the machine
sets out without any further trouble.

In employing the machine for bevelling the edges of boards as in the case of
panel cutting," we fix in the tool holder P a tool having an inclined cutting
surface, so that on actuating the carrier L, the desired bevelled edge or cut is
produced on the panel or other board operated upon.
In order to make an undercut in a piece of board, so that such piece may be
***scribed or fitted to another surface, we mount the undercutting tool Z in the
carrier Z, which will produce the desired result on the to and fro movement of the
carrier L.
It will be readily understood that various kinds of knives and cutters may be
fitted to the tool holder P to suit various classes of work to be produced, as the
machine will be found applicable for many purposes other than those above set
forth.
When it is desired to actuate the carrier L by power, we employ a face plate of
ordinary construction, having a crank arm in connection therewith, which is
coupled to the carrier L at or about the position M¹; the amount of stroke being
regulated by adjusting the crank arm in a slot across the face of the plate.
'
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The carrier beam G fulcrumed at F, whereby the carrier is enabled to
reciprocate by means of suitable mechanism, substantially as and for the purposes
set forth.
2. The tool holder P fulcrumed to the carrier L, in combination with cutting
tools and shoes for regulating the depth of cut, substantially as and for the
purposes set forth.
3. The combination of the carrier beam, carrier, tool holder, link, and hand
lever, all acting together substantially as and for the purposes set forth.
4. The boring apparatus U, clamps V and W, substantially as and for the.
purposes set forth.
5. The general arrangement, construction, and combination of the various parts
forming the machine for trenching and otherwise cutting wood or other material
by hand or by power, substantially as and for the purposes set forth.
