Southampton Buildings, London. "IMPROVEMENTS IN SHAPING MACHINES."
[A communication from abroad by Pierre Philippe Huré, of Paris, France.]
This Invention relates to a novel construction and arrangement of parts whereby
I combine in a single machine two shaping tools; it has the advantage of being
capable of instantaneous adjustment to work with either a horizontal or a vertical
shaft, and of performing upon a single object two different operations without
change of position.
The said Invention consists in,-
First. The arrangement of a movable head or frame which supports two shafts,
one vertical and the other horizontal, capable of being turned at will to work
successively on the same piece or object.
Second. The mode of fixing the frame upon its column by a movable bolt
perforated with a hole for the passage of the horizontal shaft; I may however
adapt any other suitable manner of fixing the frame and arranging the said
horizontal shaft.
Third. The arrangement of guide pulleys adjustable around an axis carrying the
driving cone for transmitting motion to the horizontal shaft or the vertical shaft
without the necessity of shifting the belt.
Fourth. A disengaging device placed inside the said cone, and serving to start or
stop the machine by means of the foot.
Fifth. The arrangement of a movable table capable of oblique adjustment for
shaping conical pieces.
In the accompanying Drawing Figure 1 is a front view, shewing the said
machine arranged for vertical operation.

page_text: The shaft A is driven by a belt passing over the pulleys B. For transforming the
machine into a horizontal one, it is only necessary to unscrew slightly the nut C,
and to give the frame D a quarter turn from the left to the right; then the
horizontal shaft E takes the place of the shaft A upon the centre of the table, the
pulley F replaces the pulleys B and receives the belt. Then the frame D is set by
the marks o which indicate the point at which the horizontal shaft is perpendicular
to the table; then it is fixed by tightening the nut C. The rotative arrangement
of the frame D permits also the oblique adjustment of the shaft E with regard to
the table when taper pieces or objects are to be shaped; for this purpose the pulley
F is considerably convex on its periphery to ensure the keeping of the strap thercon.
The driving and guide pulley apparatus G placed at the back of the machine serves
for driving both shafts at will, without necessitating any alteration of the length of
the belt.
Figure 2 shews it arranged for driving the vertical shaft. For operating the
horizontal shaft it must be placed as indicated in dotted lines, Figure 1. It is
made fast in the desired position by the aid of the screw H pressing on the
quadrant I which keeps it firmly fixed.
This pulley arrangement is furnished with disengaging gear, as shewn in
Figures 1 and 3; it is conveniently arranged for operation by the foot of the
operator.
The grooved table is mounted on a movable axis, and can be set in an oblique
position at will for shaping conical or helicoidal pieces.
Figure 3 shews the arrangement of this table, which is made fast by the aid of
two bolts, whose heads slide in a circular groove in the lower table.
Figure 4 represents in section the head of the machine, and shews the arrange-
ment of the bolt serving to fix the movable frame D upon the column. The bolt K
turns at the same time as the frame D; it is kept down by the nut L placed inside
the said column.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN SHAPING MACHINES.'
A communication from abroad by Pierre Philippe Huré, of Paris, France.
This Invention relates to a novel construction and arrangement of parts whereby
I combine in a single structure two shaping machines, the one vertical and the
other horizontal; the apparatus embodying this Invention offers the advantage that
it can instantaneously be set to work as may be desired, either with the horizontal
shaft or with the vertical shaft, and thereby allows of two operations upon a piece
of work without requiring the same to be dismounted.
My Invention consists in,-
1. The arrangement of the movable head or frame which carries two shafts, one
vertical and one horizontal, and is capable of being turned at will so as to
successively cut the same piece.
2. The manner of fixing the frame upon the standard by a movable bolt pierced
by a hole for the passage of the horizontal shaft.
I may however employ any other manner of fixing the frame, and may displace
the horizontal shaft and arrange the same, in some cases, at any other point of the
frame.
3. The arrangement of the belt tightening mechanism pivotted on a shaft
carrying a driving cone for transmitting the motion either to the horizontal shaft
or to the vertical shaft without the necessity of changing the belt.
4. The clutch gearing placed inside the driving cone and serving to start or stop
the machine by means of a pedal.
5. The arrangement of the movable table capable of assuming an oblique position
for allowing cone-shaped pieces to be mortised/
Figure 2 an end elevation partly in section; and
Figure 3 is a plan of a machine constructed according to this Invention.
Figure 4 is a sectional elevation of the head of the machine and adjacent portions
detached.
Figure 1 represents the machine adjusted to work vertically. The shaft A is
driven by belting running over guide-pulleys B, B.
To transform this machine into a horizontal shaping machine, it is only necesary
to slightly unscrew the nut C, and to give to the frame D a quarter of a turn from
the left to the right; then the horizontal shaft E takes the place of the shaft A
on the centre of the table, and the belt-pulley F takes the place of the guide
pulleys B, B, and receives the belt. The frame D is then set by the position-
inarks O, O (Figures 1 and 2), which indicate the point at which the horizontal
shaft is perpendicularly in line with the centre of the table, and the said frame is
then fixed by tightening the nut C.
The frame D being so arranged as to be capable of rotation will permit the
shaft E to be placed obliquely with regard to the table when oblique pieces are to
be cut. For this purpose the periphery of the pulley F is made considerably
convex or spheroidal, so as to afford firm hold for the belt.
The belt-tightening mechanism G arrangement at the rear of the machine permits
the driving of either of the two shafts at will, without the necessity of changing
the length of the belt.

page_text: In Figure 2 the mechanism is represented as being arranged for driving the
vertical shaft. For imparting motion to the horizontal shaft it has to be placed as
indicated by dotted lines in Figure 1. It is fixed in the required position by
means of the screw H pressing against the quadrant I, which affords it a rigid
support. This belt-tightening mechanism is provided with a clutch, the arrange-
ment of which is illustrated in Figures 1 and 3; it is so placed as to be actuated
by the foot of the operator.
The slotted table is mounted on a movable axis; it is capable of any desired
oblique adjustment to permit the cutting of cone-shaped or helicoidal pieces.
Figure 3 shows the arrangement of this table which is fixed by means of two
bolts, whose heads slide in curved slots provided in the lower table.
Figure 4 shews the construction of the bolt which serves to fix the frame D on
the standard.
This bolt K rotates together with the frame D; it is held at its lower end by the
nut L placed in the interior of the standard.
Having thus fully described the said Invention as communicated to me by
my foreign correspondent, and the manner of performing the same, I wish it
understood that I claim,-
First. In a shaping machine, a movable head carrying two shafts, one of which
is vertical and driven by the aid of guiding pulleys B, B, and the other is
horizontal and driven from the pulley F, the whole being so arranged as to permit
the same machine to cut either vertically or horizontally, as above set forth.
Second. In a shaping machine for cutting in either a vertical or a horizontal
direction, the arrangement of a head carrying a vertical shaft and a horizontal
shaft, and mounted upon the standard or framework by means of a movable
bolt perforated at its centre to afford a passage for the said horizontal shaft,
substantially as above set forth with reference to Figure 4 of the Drawing and for
the purpose specified.
Third. In a shaping machine for cutting either in a vertical or in a horizontal
direction the combination with a movable head carrying two shafts and pulleys
B, B, and F, of a belt-tightening device pivotted on the shaft of the driving cone,
and held in position by a screw upon a quadrant in such a manner as to serve for
driving either the pulleys B, B, of the shaft A, or the pulley F of the shaft E
without altering the length of the driving-belt, all substantially as herein before
specified.
Fourth. The employment of the clutch arranged within the driving cone, and
serving to start or stop the machine by means of a pedal, as shewn in the
Drawing.
Fifth. The arrangement of the movable table capable of oblique adjustment for
cutting or shaping cone-shaped pieces, substantially as above described and as
illustrated in the Drawing.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Thirtieth day of November, in the year of our Lord
One thousand eight hundred and eighty.
