COMPLETE SPECIFICATION
An Improved Turning, Shaping, and Cutting Machine.
I, WILLIAM DUFFY, of Gainsborough Road, Victoria Park, London, NE, Wood-
block Flooring and Paving Manufacturer, 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.—
This invention relates to novel, means employed in combination, for turning,
shaping, and cutting oft with great rapidity and perfect accuracy, various small
articles such as pins, dowels &c, and of varied configuration accordingly as may

In order that the nature, objects, and scope of my said invention may the better
be understood, I will now proceed to describe same in reference to the accom-
panying sheet of drawings in which the same letters and numerals of identification,
are employed to denote like or cone-ponding parts throughout the several views
In the diawings, Figure 1 is a side elevational view of my improved turning,
shaping and cutting machine, Figure 2, plan view, Figure elevational view
at feeding end of the machine Figure 4. detached face view to enlarged scale of
the hereafter referred to
gupping chuck
Figure 5 plan view of the drawing
at Figure 4, Figure detached view shewing the mechanism for releasing, and
tightening, respectively, the gap of the chuck on the stick of 1ough material
being operated upon. Figure 7 is a detached view of screw operating lever at
right angles to Figure 6, Figure 8 detached view of adjustable cam plate for
operating the feeding 1oller of the device The several parts or members men-
tioned above, are hereunder identified and then respective functions set forth
and described.
a, 19 the bed plate, b, sliding carriage to which the work is centred, and which
cares the circular saw and rotating cutters d, of any desired shape, e 18 an auto-
matic gupping and releasing chuck diven by stiap and pulley at f, e¹, e', sliding
blocks or jaws, adjustable by means of 11ght and left handed screws e³ for gupping
the 1ough material to be tuned or machined g, strap passing over the
pullers, mounted on then respective spindles, for driving saw and
cutters, represents the strip or stick of material which is to be turned or
machined It is fed through the hollow mandel mounted on the bed plate a,
until it reaches the cutters d at the other end of the machine, 7, 7' are feeding
rollers provided with V shaped surfaces for gupping the stick of 1ough material
to be fed forward One of these 1olleis, is formed with studs or projections 29
for engaging the diagonally disposed rib A, formed on the plate (Figure 8)
provided with an arm and pivoted to a 1od or bar k attached to The plate ¹
is operated by the cam 7. mounted on shaft operated by the geared wheels, B ;
thus securing the periodic engagement of the studs on projections in the plate k³,
which is thrown into gear at the required time
Reverting to the before mentioned pullevs g', q', their respective spindles are
mounted on a sliding base parallel wise to each other (see plan Figure 2) as also
to the stick of material to be machined One of said spindles has mounted on its

page_text: outer end, the 1otary cutter or shaping tool d, and the other carries at its outer
end the cucular saw c, as shewn in the diawings, the spindles of both the saw,
and the shaping tool, being driven at a high rate of speed relatively to that of
the gupping and releasing chuck e is a lever mounted on a shaft e* and pro-
vided with studs or projections The lever e³ is brought into working position
by the agency of the cam e, operating the lever e', as shewn Figure 6; the cam
piece coming into contact with the studs during the revolution of the chuck
as aforesaid.
It will be seen on reference to Figures 1 and 2, that on the carriage b 18 super-
posed another carriage b'. This latter carries the saw, and shaping tool, and
has imparted to it a reciprocatory transverse movement for feeding up the saw
and shaping tool to their work, by means of the cam m (Figures 1 and 2) operating
the lever m mounted on shaft m³, which latter operates the level m³ connected by
the rod m to the sliding carriage b¹ aforesaid
b
The
The end of the stick of material h being machined, is held by a point or centre
seen in Figures 1 and 2, carned by a levein, pivoted at n¹ to the under carnage
and maintained in contact with the sliding carnage 6 by a spring n³ (Figure 2).
The sliding carriage 61 18 recessed at 62 (Figure 2), so that, as the caulage 61 slides
to draw back the tool d, the sping aforesaid, pulls back the lever n with its
centre point against the recessed part aforesaid. 6, of the sliding carriage
cams 1, m, and e, are each mounted on the same shaft and are operated by the
geared wheels 12, 13 (Figures 1, 2, and 3) The set-screw 63, seen in Figure 1, is
provided for the purpose of adjusting the transverse motion of the sliding
carnage b¹, and to regulate the depth of the cut, by means of a projection on the
carriage coming into contact with the end of the set-screw 69
o (Figure 1) is a hand screw for regulating the position of the sliding canlage
relatively to the length of the strip of material to be machined
When in operation, the shaping cutters at d, having been advanced against the
evolving stick of material h and machined it to the desired form and dimensions,
then, this having been effected, the cutters will recede, and simultaneously, the
cutting-off saw will be brought forward, and the operation of severing the
machined portion of the stick of material h, will be effected Also, coincidently
with the retirement of the cutters, the centre point (Figures 1 and 2) which held
the stick of material being machined, also retires fioni the latter and allows the
dowel or other machined object or article to fall clear, and be received in a suitable
1eceptacle.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same 18 to be performed, I declare that what
I claim 18
-
The novel combination device for effecting automatically with great rapidity
and perfect accuracy the threefold functions of turning, shaping and cutting off
from the rough material, various small articles, all substantially as herein described
and shewn and identified in the accompanying sheet of drawings.
Dated this 22nd day of December 1898.
