Improvements in Machinery or Apparatus for Trimming or Finishing
the Ends and Sides or Outer Edges of Wood Boxes, Frames, and
other Articles.
We ALFRED BRIDGMAN of Trewsbury House, Trewsbury Road Sydenham in
the County of Kent Managing Director and DAVID HOUSE of 16 Macclesfield
Street City Road in the County of Middlesex Engineer do hereby declare the
nature of the said invention to be as follows:-
The invention relates to machinery or apparatus for trimming or finishing the
ends and sides or outer edges of wood boxes frames and other articles. For the
purpose of trimming or finishing the ends of boxes and such like articles we employ
a table carried by a suitable frame and fixed at a slight angle with the back
portion of the frame which latter rises to a suitable height above the table. In the
back I form a quadrant shaped V guide to receive a planing tool the plane iron of
which is set at an angle with the top of the table so as in its motion to produce a
draw cut. The quadrant shaped V groove represents the upper portion of a circle
so placed in relation to the table that although employing a narrow plane iron the
latter is enabled to do effective work from one end to the other of its stroke or
nearly so.
The planing tool is moved to and fro by a vertical lever the upper end of which
enters an aperture in said planing tool and the lower end of which is pin jointed
at the point from which the quadrant is struck or the quadrant may be of larger
radius than the length of the lever, in which case the upper end of the latter will
be connected with the planing tool by a link or such upper end will run in a slotted
guide carried by such planing tool. Said lever is connected by a link with a crank
pin carried by a disc the axis of which is mounted in suitable bearings and receives
rotary motion by hand, steam or other power.
For the purpose of trimming or finishing the sides of boxes and such like
articles we employ apparatus constructed generally similar to that above described
except that we use a straight V guide for the planing tool and in such case we fit
the upper end of the driving lever with a pin to enter a vertical slotted guide
carried by the planing tool and to move to and fro therein whilst giving motion
to the planing tool or a link may be employed to connect the upper end of the
lever with the planing tool.
For both purposes we employ adjustable guides or fences on the table as hereto-
fore to adjust and hold the work in the required position and according to our
invention we fit the rising portion of the back of the machine with an adjustable
guide the face of which is at a right or other required angle with the surface of
the table and such guide tapers off thin at its lower edge and is capable of coming
in front of the plane iron so as to prevent a shallow box from being pressed too far
towards the plane.
It will be evident that the outer edges or surfaces of frames and various other
articles may be trimmed or finished by the aid of machinery constructed as above
described.

Improvements in Machinery or Apparatus for Trimming or Finishing
the Ends and Sides or Outer Edges of Wood Boxes, Frames, and
other Articles.
We ALFRED BRIDGMAN of Trewsbury House Trewsbury Road, Sydenham,
in the County of Surrey Managing Director and DAVID HOUSE of 16 Maccles-
field Street City Road in the County of Middlesex Engineer 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 invention relates to machinery or apparatus for trimming or finishing the
ends and sides or outer edges of wood boxes frames and other articles. For the
purpose of trimming or finishing the ends of boxes and such like articles we
employ a table carried by a suitable frame and fixed at a slight angle with the back
portion of the frame which latter rises to a suitable height above the table. In
the back we form a quadrant shaped V guide to receive a planing tool the plane
iron of which is set at an angle with the top of the table so as in its motion to
produce a draw cut. The quadrant shaped V guide represents the upper portion
of a circle so placed in relation to the table that although employing a narrow
plane iron the latter is enabled to do effective work from one end to the other of
its stroke or nearly so.
The planing tool is moved to and fro by a vertical lever the upper end of
which enters an aperture in said planing "tool and the lower end of which is
pin jointed at the point from which the quadrant is struck, or the quadrant
may be of larger radius than the length of the lever, in which case the upper
end of the latter will be connected with the planing tool by a link or such
upper end will run in a slotted guide carried by such planing tool. Said lever
is connected by a link witli a crank pin carried by a disc the axis of which is
mounted in suitable bearings and receives rotary motion by hand steam or other
power.
For the purpose of trimming or finishing the sides of boxes and such like
articles we employ apparatus constructed generally similar to that above described
except that we use a straight V guide for the planing tool and in such case we
fit the upper end of the driving lever with a pin to enter a vertical slotted guide
carried by the planing tool and to move to and fro therein whilst giving motion
to the planing tool or a link may be employed to connect the upper end of the
lever with the planing tool.
For both purposes we employ adjustable guides or fences on the table as hereto-
fore to adjust and hold the work in the required position and according to our
invention we fit the rising portion of the back of the machine with an adjustable
guide the face of which is at a right or other required angle with the surface of
the table, and such guide tapers off thin at its lower edge and is capable of coming
in front of the plane iron so as to regulate amount to be trimmed off and to
prevent a shallow box from being pressed too far towards the plane.
And in order that our said invention may be more clearly understood and readily
carried into effect we will proceed aided by the accompanying drawings more
fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a back view Fig. 2 is a cross-section and Fig. 3. is a plan of machinery
or apparatus constructed according to our invention for trimming or finishing
the ends or outer edges of wood boxes, frames and other articles.
Fig. 4. is an elevation Fig. 5. is an end view. Fig. 6. is a longitudinal section
and Tia 7 is a sido riaw of the ul

page_text: Fig. S is a face view of the plane iron separately.
Fig. 9. is a side view partly in section and Fig. 10. is an elevation also partly
in section showing a straight planing tool and the upper end of the lever for
operating the same to be used in machinery or apparatus for trimming or finishing
the sides or outer edges of wood boxes, frames and other articles where such sides
or edges are too long to be trimmed or finished by a machine having a plane
travelling in an are of a circle, and Fig. 11. is a face view of the plane iron
separately.
In all the figures like parts are indicated by similar letters of reference.
Referring firstly to the machine represented at Figures 1 to 8, a, is a table which
is fixed to the tops of two standards b, b, whose lower ends are bolted to a base
plate. This table 4 is fixed at a slight angle with the back portions_d, d*, of
the frame and the part, d, of the back rises to a suitable height above the
table, a.
The part d, of the back is fixed to the table top, a, by a bolt, e, and a bracket,
at each end thereof and the part is fixed at each end to the standards b, b, and
in the centre to a web, a, descending from the back of the table, a. The lower
edge of the part d and the upper edge of the part d" are so curved and bevelled
as to form a quadrant shaped V guide to receive a planing tool whose body, g
is.
shaped to fit such V guide with capability of freely sliding to and fro therein; the
cutting edge of the plane iron g', is set at an angle with the top of the table, a, so
as in its motion to produce a draw cut. The plane iron is adjusted in the body g
of the plane by screws passing through lugs and fixed in position therein
by nuts and whose heads fit into slots in the plane iron and the latter
when properly adjusted is fixed firmly to the body g of the plane by a screw g.
The quadrant shaped V guide represents the upper portion of a circle of such
proportions and so placed in relation to the table, a, that although employing a
narrow plane iron the latter is enabled to do effective work from one end to the
other of its stroke or nearly so.
The planing tool is moved to and fro by a vertical lever the upper end of
which enters an aperture in the body of the planing tool and the lower end of
which is pin jointed to a bearing at the point from which the quadrant is struck
or the quadrant may be of larger radius than the length of the lever in which
case the upper end of the latter will be connected with the planing tool by a
link as will be readily understood or such upper end will run
in a slotted
guide carried by such planing tool or it may as shown at Figures 9 and 10 be
formed at its upper end with a slotted guide 42 working in a space formed in
the planing tool and receiving a block pin jointed to the body y of the planing
tool. The lever is connected by a link with a crank pin carried by a disc j
the axis of which is mounted in suitable bearings fixed to the upper ends of
standards fixed to the base plate c.
1,3
On the axis are mounted two pulleys which may be driven by a strap or
band from a steam engine or other power or such axis may be driven by hand.
is an adjustable guide or fence which is capable of being fixed in any required
position on the table a against which the work is adjusted and held. The rising
portion d, of the back of the machine is fitted with an adjustable guide m, the face
of which is set at a right or other required angle with the surface of the table a
and such guide tapers off thin at its lower edge and is capable of coming in front
of the plane iron so as to regulate or adjust the amount to be trimmed off each
box or article and also to prevent a shallow box from being pressed too far
inwards towards the plane. Said guide m is adjusted in height by means of Ay
nuts m' acting on screws m² fixed to the guide m and passing through lugs m³ fixed
to the upper edge of the part d, whilst when adjusted it is firmly fixed in position
by means of fly nuts m mounted on screws m³ fixed to the guide m and passing
through vertical slots in the part.d.
Machinery or apparatus constructed as above described is designed for trimming
the ends of boxes and other articles but it can of course be employed for trimming

page_text: the sides of boxes and other articles whose length is not too great to be fully
acted upon in said machine.
For the purpose of trimming or finishing the sides of boxes and other articles of
greater length than can be effected in the machine represented at Figures 1 to 8
we employ apparatus of generally similar construction to that above described
except that we use a straight V guide for the planing tool represented at Figures 9
and 10 whose body is formed to fit the same and in such case we fit the upper end
of the driving lever, h, with a pin to enter a vertical slotted guide carried by the
planing tool and to move to and fro therein whilst giving motion to the planing
tool or a link may be employed to connect the upper end of the lever with the
planing tool or we preferably construct the upper end of the lever as shown at
Figures 9 and 10, and as before described.
The plane iron represented at. Figure 11, has its slots formed with open
sides thereby enabling it to be applied to and removed from the planing tool more
readily than when having slots of the form shown at Figures 4 and 8.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. The peculiar construction and arrangement of machinery or apparatus for
trimming or finishing the ends and sides or outer edges of wood boxes, frames
and other articles substantially as herein shown and described.
2. In machinery or apparatus for trimming or finishing the ends and sides or
outer edges of wood boxes, frames and other articles the combination of an inclined
table and vertical back fixed at a slight angle with each other, a segmental or
horizontal V guide in said back, a planing tool working in said V guide an
adjustable guide in front of the planing tool and a radius driving lever working
on an axis of motion close to the base plate for giving motion to the planing tool
substantially as herein shown and described.
3. In machinery or apparatus for trimming or finishing the ends and sides or
outer edges of wood boxes, frames and other articles, an adjustable guide, such
as m, placed in front of the planing tool whereby the amount to be trimmed off
each box or article can be readily adjusted and whereby a shallow box is prevented
from being pressed too far inwards towards the plane substantially as herein shown
and described.
