page_text: I JOSEPH HARTLEY WICKSTEED of the firm of Joshua Buckton & Co Limited of
Wellhouse Foundry, Leeds, Yorkshire, Tool Makers, do hereby declare the nature
of this invention to be as follows:-
This invention relates to certain details based upon a previous Patent granted to
Joseph Angus on the 13th March 1880 N° 1091. In the Specification of that
Patent great stress is laid upon the employment of a tool on the double cutting
principle fitted in a cylindrical fulcrum holder and various forms of the tool on
the double cutting principle, are illustrated in the Drawings annexed to that
Specification.
Now the object of the present invention is to employ two independent single
cutting tools in distinct swivel holders carried by the same single stock but
provided with springs which couple the stocks in pairs The tools are arranged
either with their cutting faces looking outwards in two opposite directions or
looking inwards opposite each other.
The planing machine is by preference made to take a self acting feed at each.
end of the stroke, but the tools may be adjusted so as to divide the feed which is
given at one end only of the stroke.
By means of this improvement the necessity for tipping the tool holder by
mechanism, is dispensed with as each independent tool holder may be made self
acting in its relief action by spring or gravity, so that the tool becomes firmly held
during the cut and able to relieve itself during the return stroke.
The invention is applicable to all Planing Machines in which the table travels
and also to those machines in which the work is stationary, and the tool box
travels known as side Planing Machines or Wall creepers.
The invention is applicable also to all slotting and shaping machines especially
those of long stroke.

Improved Construction or Arrangement of Tool Holder for
Planing and like Machines for Two Tools, Available for
Cutting during the Forward and the Reverse Travel of the
Machine Table or of the Tool Box.
I, JOSEPH HARTLEY WICKSTEED, of the firm of Joshua Buckton and Company,
Limited, of Wellhouse Foundry, Leeds, Yorkshire, Tool Makers, 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 this invention, is to employ two independent single cutting tools
in distinct oscillating holders, which do not require to be moved by tappet gear,
and are preferably carried by the same single stock. The tools are arranged either
with their cutting faces looking outwards in two opposite directions, or looking
inwards opposite each other. Ŏr the invention is applicable for holding a single
tool, to cut in one direction and to be able to relieve itself on the back stroke.
The planing machine is by preference made to take a self-acting feed at each
end of the stroke; but the tools may be adjusted so as to divide the feed which is
given at one end only of the stroke.
Each independent tool holder is made self acting in its relief action, by spring
or gravity, so that the tool becomes firmly held during the cut and able to relieve
itself during the return stroke.
The invention is applicable to all Planing Machines in which the tables travel,
and also to those machines in which the work is stationary, and the tool box
travels, such as side planing machines or "wall creepers."
The invention is applicable also to all slotting and shaping machines, especially
those of long strokes.
My invention will be clearly understood by the annexed drawings in which
at Figure 1 I show a part sectional side elevation, Figure 2 a side elevation and
Figure an edge view of a tool stock A with two tools B, B, fitted in cylindrical
holders C, C, which are secured in and yet have a free oscillating motion in the
stock A to move over, and accomodate themselves, as each tool is brought into
work for cutting, said. tools being set in opposite directions with their cutting
edges to act during each travel of the table, or at each travel of the tool stock as
the case may be. The heads or stems D, D, of the tools B, B, impinge against a
box spring E.
Figure 4 is a perspective view of a plug screw F and Figure 5 a section showing
the cylindrical holders constructed in two parts C and G, and the arrangement
of the tools in them. Figures 7, 8, and 9 show modifications of my invention.
The tool on coming into action assumes a position with its lower end abutting
against the stock at L to resist the strain of the cutting operation. The other or
idle tool is then free to adjust itself and yield during the return stroke of the table,
or of the stock.

page_text: In some cases the spring E may act upon an attachment made to the oscillating
cylindrical tool holders, and without the tool itself impinging upon the spring box,
as shown at Figures 6, 7 and 9.
Each cylindrical tool holder is made of two pieces, screwed together, and the tool
after being inserted in a slot in the main piece, is fixed in position by plug screws F,
one of which I show at Figure 4, said plug screw having a recessed face for the
insertion of a square key by which it can be readily turned.
Figure 6 shows the spring E arranged between two attachments, or lugs H, on
the cylindrical holders C, C, of two tools B, B, which may be of self hardening steel
of any section suitable for use without being smithed into shape. Figure 7 is an
edge view and Figure 8 a sectional elevation of the same. Figure 9 is an elevation
of a single tool stock with oscillating holder and relief gear.
The spring E is preferably arranged around a rod passing through the lug or
lags H, H, but one spring does not need to be common to both tool holders; as two
independent single tool stocks, each containing a cylindrical holder and tool, may be
arranged or fixed back to back if desired.
During work the tool B rests against the lower portion L of the stock which
serves as an abutment. The tool stocks or holders A A are reversible as will be
seen from their shape.
Figures 9 and 10 show the application of my double cutting tool holder, to an
ordinary planing machine, in which the table moves. The tool box M, (see
Figure 10.) is shown carrying the tool stock A and holders, fixed for side cutting
and the tool box N is shown in position for planing over a horizontal surface.
Figure 11 shows a side elevation of a planing machine, with a suitable
arrangement of pawl and ratchet gear P, Q, for giving a feed motion at each end
of the stroke of the table R. The driving gear is so arranged, as to be capable of
driving the table R, at a uniform speed for both cuts, or to give it a quick return
motion when required, as in cases where the work is of such a nature that one of
the tools only in each holder can conveniently be brought into action. For this
kind of work, I prefer to employ a tool stock, or holder having the same relief
action, and of a similar form and reversible as above described; but carrying only
one tool in a circular oscillating holder.
I do not claim, auy special planing, or shaping machines, or any special
arrangements for feed gear, or driving gear.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
1. The two cylindrical holders C, C, each carrying a single faced cutting tool B,
in combination with a spring arrangement as described, and as shown in the
annexed drawings for the purposes set forth.
2. The construction of a reversible tool stock, to contain two tools, or sections of
tool steel, of comparatively small proportions in circular oscillating holders, with
relief action, herein before described and capable of being employed either for
double cutting, or for single cutting.
