I, THOMAS SHURMER, of 306, Manchester Road, Bolton, in the County of
Lancaster, Joiner and Builder, do hereby declare the nature of this invention
to be as follows, that is to say:-
It relates to improvements appertaining to wood-working machinery known
as tenoning and trenching machines and particularly of the class wherein the
rotary tool is arranged with its shaft in the horizontal plane, and this invention
consists in the addition of a supplementary tool and means for operating same in
the vertical plane together with a new form of cutter and additional table con-
structed for holding the wood to be acted upon.
In carrying my invention into effect I mount an additional spindle in bearings
fixed to the ordinary framework, to support said spindle in a vertical position,
this spindle is rotated by suitable driving belt or cord devices which are arranged
by appropriate guide pulleys and intermediate shafts so as to transmit motion
thereto as desired.
The cutter is somewhat of hollow cylindrical or tubular form and has its cutting
edges formed on its outer end, such edges being two or more in number as may
be desired.
The table, upon which the wood to be operated upon has heretofore been placed,
has in accordance with my invention, strips or guide-pieces secured to its upper
surface to form V or dovetail grooves to receive the ribs or projections fixed to
an additional table to be mounted thereon so that as said additional table is desired
to be moved beneath the rotary cutter, these guide-pieces will retain
it in its proper path. The guide-pieces on the table are preferably
in pairs which are arranged at appropriate angles to each
other 50
as to guide the additional table in one direction when placed in one set of
guides, and in another direction when placed in the other set of guides so that
the wood to be acted upon when secured to this additional table may be guided
and held in contact with the cutter so that the various operations thereon may
be carried out as desired.
It will readily be understood that instead of the vertical spindle and additional
table being mounted upon the framework and table of the ordinary tenoning or
like machine, they may have separate framework and table arrangements, thus
forming a complete and separate machine.

I, THOMAS SHURMER, of 306, Manchester Road, Bolton, in the County of
Lancaster, Joiner and Builder, 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, that is to say: -
It relates to improvements appertaining to wood-working machinery known
as tenoning and trenching machines and particularly of the class wherein the
rotary tool is arranged with its shaft in the horizontal plane, and this invention
consists in the addition of a supplementary tool and means for operating same in
the vertical plane together with a new form of cutter and additional table con-
structed for holding the wood to be acted upon.
In the accompanying sheets of drawings:-
Fig. 1 is a front elevation of a machine with my improved parts applied
thereto.
Fig. 2 is a view of the parts shown by Fig. 1 as seen from above, with a
portion of the table removed.
Figs. 3 and 4 are drawings in detail showing certain of the parts as herein-
after described.
Figs. 5 and 6 are sectional end view and side elevation of my improved form of
cutter.
Fig. 7 is a drawing in detail illustrative of one of the purposes for which my.
improved machine may be used
Similar letters and figures of reference indicate similar parts throughout the
several views.
In carrying my invention into effect in connection with machines of the class
especially referred to wherein a horizontal shaft a is arranged to carry the usual
rotary cutting tool, I mount an additional spindle b in bearings c c¹ secured to the
ordinary framework A so as to support said spindle b in the vertical position
shown.
This spindle b has rotary motion transmitted to it from the machine's main
driving shaft d through the pulleys e e¹ driving belt f shaft g and bevel wheels h h¹
the driving belt for operating the ordinary shaft a being thrown out of use
when the belt f is in operation.
The cutter I preferably form of a hollow cylindrical or tubular shape (see
Figs. 5 and 6) with its cutting edges formed as shown.
The table m, upon which it has heretofore been usual to place the wood about
to be subjected to the cutting operations, has in accordance with my invention
strips or guide pieces n n¹ and n² n³ secured to its upper surface to form V or
dovetail grooves to receive ribs or projecting flanges pp or p² 23 (of corresponding
shape) fixed to an additional table r or which is to be mounted thereon so
that as this said table r is desired to be moved beneath the cutter k these guide
pieces nn operating in the grooves p p² or the other table having the
guides n² n³ operating in the grooves 22 p³ will retain it in its proper path, these
guiding surfaces being preferably in pairs on the table m as stated and at
appropriate angles to each other so as to guide the table or 1 in one direction
when one set of guides are employed and in the other direction when the other
set are used so that the pieces of wood (as for example of the shape shown by
Fig. 7) to be subjected to the cutting operations when secured to this table r or l
may be guided and held in contact with the cutter k so that the various cutting
operations thereon may be carried out, in other words the cutter k may be made

page_text: to produce the series of furrows s in the piece of wood t by the table r being
employed (in which case the guides n n operate in the grooves p p¹) while
the furrows w are produced by removing said table r, from the table m and
mounting thereon the table ri (in this case the guides n² n³ operate in the
grooves 223) To produce these series of furrows in the board tit has to be
moved or slided lengthwise upon the table r or r¹ to bring it into position relatively
with the cutter k for each separate furrow to be made its position on the table r
or being regulated by the adjustable fence x pivotted at r¹ and held by
screws, so that said furrows s or w may be made at any desired angle to
the edge of the board t.
Although I have herein only described my invention as being applicable for
use in connection with the type of machine referred to, it will readily be seen
that I may arrange my duplex table devices upon any suitable framework upon
or in connection with which a rotary spindle is mounted vertically so that the
machine produced will be complete and distinct from the class hereinbefore
referred to.
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 what
I claim is:-
1. In mechanism of the class described, a rotary cutter and table devices for
holding and guiding articles to be treated by said cutter substantially as herein
specified.
2. In mechanism of the class described, a rotary cutter constructed as shown,
a table for supporting the article to be treated by said cutter and another table
for supporting the former the same being constructed and arranged to operate
in combination substantially as herein specified.
Dated this 21st day of December 1898.
