Improvements in Machinery for Shaping Wooden Handles and
the like.
I, ROBERT GRAHAM BURLEIGH, of 5, Ibrox Place, Ibrox, in the County of
Renfrew, North Britain, Handle 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, that is to say :-
My said invention relates to the kind of machinery employed for making wooden
hammer handles and similar articles of irregular or regular cross section, and
comprises improvements in such machinery, which whilst effecting a great saving
in time and labour, insure great accuracy and good quality of work.
The invention comprises improved devices, hereinafter described, by means of
which a hammer handle or similar article can be shaped of any desired or suitable
cross section at either or both ends, and also improved centering devices by means
of which short articles can be shaped in large machines without removing any of
the cutters as is usual. There is also comprised in the invention improved
automatic gear which feeds the article to be shaped steadily against the cutters,
and brings it away from them when finished; and devices are also provided by
means of which one article can be centered while another is being shaped.
And in order that my said invention and the manner of performing the same may
be properly understood I hereunto append five sheets of explanatory drawings, to
be hereinafter referred to, and showing examples of my improved machinery.
Figures, 1, and, 2, on Sheets, 1, and, 2, of the drawings are perspective views of
one example of my improved machines Figures, 3, and, 4, on Sheets, 3, and, 4, being
also perspective views of another example. Figures, 5, and, 6, on Sheet, 5, are
respectively a plan and back elevation of a sliding cutter frame appertaining to the
first machine. Figures, 7, and 8, are elevations as at right angles to each
other of some parts connected with the second machine and not quite clearly shown
in Figures, 3, and, 4. Figure, 9, is a horizontal section, Figure, 10, is a longitudinal
section, and Figure, 11, is an end elevation of an improved centering device.
Figure, 12, is a sectional plan, and Figure, 13, a longitudinal section of a modified
centering device. Figure, 14, is a sectional front elevation of an arrangement of
centering devices, arms forming part of or connected with these devices and herein-
after referred to, being shown in a vertical position to facilitate explanation, their
position when in use being nearly horizontal. Figure, 15, is an end elevation of a
part of the machine and gear employed in connection with the devices shown in
Figure, 14, and Figures, 16, and, 17, represent a detail. Figure, 18, is an
elevation of a detail of the first example of my machine. In these drawings the
same reference letters and numerals are used to mark the same or like parts
wherever they are repeated.
In the machine shown in Figures, 1, and, 2, which is of a kind sometimes
employed in shaping hammer handles and similar comparatively light articles, a
series of detachable rotating cutter heads, A, are provided to operate on the article
to be shaped, and they are arranged on a shaft, A 1, carried by brackets, A 2,
which are fixed to the framing, B, of the machine. The article to be shaped is
held between centres, C, and, D, arranged in brackets, C 1, D 1, which are fixed
to or it might be formed on the upper part, E, of a rocking table or carrier, G.
The rocking table, G, is made in two parts, the upper part, E, being fixed to the
lower part, F, by a bolt, E 1, which acts as a pivot and is adjustable along the
length of the table; and the lower part is hinged on a shaft, F 1, rocking in
bearings, F 2, on the framing, B, of the machine. In Figure, 1, the table, G, is
shown as rocked inward to the position for operating on the haminer handle, E 2,

page_text: To
while in Figure, 2, it is shown as rocked outward away from the operating position.
The centre, C, which carries the end of the handle, which is to fit into the eye of
the hammer head, is formed so that two removable cams, C 2, C 3, can be fixed on
it, one, C 2, of which is shaped like the required cross section of the handle, near
that end the other, C 3, being like the required cross section of the eye part of the
handle. A revolving movement is imparted to the centre, C, by gearing at-the
side of the machine in the ordinary way, and this movement white the cutter
heads, A, are acting on the wood causes the cam, C 2, to bear on a small
bracket, C4, on the framing, B, and moves the table with its upper and lower
parts, E, and, F, from and towards the cutters at that end so that the handle, or
other article is reduced to a cross section similar to the contour of the cam.
carry the cam, E3, for the other end, a shaft, C 5, is provided working in
bearings, C6, at each end, and having fixed on one end of it a pinion, C 7, gearing
with a pinion, C 8, of the same size on the shaft, C 9, which carries the centre, C.
The cam, E 3, which is removable and may be of any desired shape like the others
is arranged to bear, as the wood is being reduced by the cutters, on a small
piece, C4, on a bracket, B 1, fixed to the framing, B, of the machine and by the
revolving movement imparted to it by the pinions, C 7, and, C 8, causes the upper
part, E, and lower part, F, of the rocking table, G, at that end to move away from
and towards the cutter heads, A, and thereby cause the hammer handle to be
shaped at that end_to a shape like that of the cam. By means of these
cams, C2, C3, and, E 3, and parts connected with them the hammer handle can be
shaped at the ends to any desired cross section according to the shapes of the cams
employed.
A bar, H, formed with notches, H 1, and fixed to the upper part, E, of the
rocking table, G, is provided to engage with and retain the hand lever, H 2, by
means of which the centre, D, is forced to grip the wood to he shaped.
A separate cutter head, A, is provided to form that part of the handle which fits
into the eye of the hammer head. This cutter head, A, works in a frame, A 3,
which is arranged to slide on two guide rods, A. 4, passing through and fixed to two
blocks, A 5, arranged on a rod, A 6, carried by two large brackets, A 7, fixed to
framing, B, of the machine and extending upwards. The guide rods, A 4, are
bound at their top ends by a small semi-circular plate, A. 8, and at their bottom
ends by the rods, A 9, to brackets, G 1, and, G 2, the latter being fixed on the large
bracket, A. 7. On the lower part, F, of the rocking table, G, there is fixed a
bracket, F 3, to which is fixed a curved bar, F 4, extending upwards and having
a slot, F 5, formed in its upper part. Passing through this slot, F 5, and resting
on the bar, F 4, is a curved lever bar, F 6, the outer end of which is jointed to the
upper end of the bracket, GI, the inner end fitting into a slot, F7, formed in
an extension, F 8, of the cutter frame, A 3. The closeness of fit of the inner
end of the bar, F6, with the slot, F7, in the extension, F 8, can be regulated
by a set pin (not shown) screwed into the upper part of the extension of the
frame, A 3. A handle bar or lever, F 9, is fixed to the under part, F, of
the rocking table, G, so that the table may be easily rocked inwards and outwards
as required. When the rocking table, G, is out, as shown in Figure, 2, and it is
desired to rock it in for use, the handle lever, F 9, is actuated and the table
rocking on the shaft, F 1, carries with it the bar, F 4, the top end of which
passes along the curved bar, F6, which rests on it and supports the cutter
frame, A 3. The top end of the bar, F 4, is lowered by the rocking of the
table, G, and by means of this and the sharp curvature of the inner end of the long
bar, F 6, the cutter head, A, and frame, A 3, drop into the operating position shown
in Figure, 1, from the position they are shown in in Figure, 2. The extension, F 8,
of the cutter frame, A 3, is connected by a pin, J, and a rod, J 1, to a semi-
circular bar, J 2, which is hinged by a pin, J 3, to a small vertical bracket, J 4,
fixed to the upper part of the large bracket, A7, and acts as a counter-balance.
The shape and disposition of the semi-circular bar, J 2, is such that it will act least
on the cutter frame, A 3, when it is down in the operating position and most when

page_text: it is raised up. The cutter frame, A 3, has fixed to its side a small rod, J 5, curved
at its under part which extends downwards and bears on the cam, C 3. This
cam, C3, when revolving acts on the small rod, J 5, and moves it and the cutter
head, A, up and down thereby reducing the eye part of the hammer handle to a
cross section corresponding to the shape of the cam. The shaft, J 6, on which the
cutter head, A, rotates extends out through its bearings, J 7, on the cutter frame, A 3,
and on one end of it a pulley, J 8, is keyed and is driven by a belt, J 9, from a
pulley, K, on a shaft, K 1, carried by small brackets, G 2, fixed to and extending
out from the large brackets, A. 7. The shaft, K 1, is driven by the pulley, K 2, on
its other end which in turn is driven by a belt (not shown) from the factory shafting
or otherwise.
A counterweighted curved bar or lever, L, hinged near its middle
part to the bracket, A. 7, has its lower end bearing on the article that is being
shaped and steadies it against the thrust of the cutter heads, A. Small vertical
bars, B 2, are fixed to the framing, B, of the machine and on these the lower part, F,
of the rocking table, G, rests when it is rocked out from the operating position.
The parts last herein before described might be modified to suit the shaping.
of larger articles such as balusters, and table legs and the sliding frame, A 3,
and cutter heads, A, might be arranged so as to give in one operation different
shapes to the article at different parts of its length alternately with the main
cutter heads, A, at the back. In this case the sliding frame, A 3, and
shaft, J 6, carrying the auxiliary cutter heads, A, would be extended horizontally,
and he fitted with as many cutter heads as desired other parts connected with the
frame being suitably arranged. A cam (C3) and a curved rod, (J 5,) would also
be provided at the other end of the machine to support and give the movement to
that end of the sliding frame, (A 3,) the cam being fixed on the shaft, (C5,) and
the rod on the frame. This modification of the parts would prove very useful as an
article could be shaped differently, such for instance as oval and square, alternately
along its length.
In Figures, 3, and, 4, a modification of the machine is shown suitable for
shaping larger articles such as fore-hammer handles and table legs. In this case
the cams, C2, and, E 3, are fixed on a shaft, C5, working in bearing brackets, C 6,
which are fixed to the upper part, E, of the table, G. In this case the parts, E,
and, F, of the table, G, actuated by gearing, hereinafter described, slide hori-
zontally with the wood, from and towards the cutter heads, A, on friction
rollers, B 3, fitted on the framing, B, of the machine and working in grooves, B4,
formed in the under part of the table. The upper part, E, of the sliding table, G, is
fixed as before by one bolt, E 1, to the lower part, F. The piece of wood from
which the handle is to be formed having been fixed between the centres, C, and, D,
(of which I provide improved forms shown in Figures, 9, to 13, hereinafter referred
to) the table, G, is moved in towards the cutter heads, A, and is actuated so as to
give the required shape by the cams, C 2, E 3, which bear on brackets, C 4, carried
by larger brackets, M, fixed to the end framing, B. The shaft, C5, carrying the
cams, C2, and E 3, is driven by a pitch chain, N, acting on a sprocket wheel, N 1,
on the shaft from a sprocket wheel, N 2, on the shaft, N 3, carrying the working
centre, C. In addition to the ordinary weight attached to or formed on the lever, N 4,
for causing the centre, D, to grip the wood, I fix to the lever a spring, N 5,
arranged to engage with notches, N 6, in a curved rack, N 7, which is fixed to a
bracket, N 8, carrying the centre, D. The spring, N 5, engaging with the
notches, N 6, on the rack, N7, retains the lever, N 4, at the place to which the
worker pulls it. Instead of counterbalancing the swinging cutter head, A, and
frame, A 3, by a spring as is usual I prefer to employ a weight or weights, L 1,
suspended by a lever, L 2, from an upwardly extending bracket, L 3, the bottom
end of which is fixed to the framing, B, of the machine.
The under part, F, of the sliding table, G, is connected by rods, L-4, to arms, L5,
keyed on a shaft, L 6, carried in bearings, L 7, and extending along the machine.
The shaft, L 6, is clipped tightly near one end by two glands, L8, to which
there is fixed a long curved lever, L 9, having a weight, P, suspended from its

page_text: outer end. Instead of the glands, L 8, an eve-block might be fixed to the lever, L 9,
and keyed on the shaft, L 6. The lever, L 9, rests on a curved bar, Q, having at
its outer eud a small friction pulley, Q1, and having its inner end fixed on a
shaft, Q2, working in a bearing bracket, Q3, fixed to the end of the framing, B.
Keyed on the shaft, Q 2, is a bevil pinion, Q4, and a large friction pulley, Q5, the
latter of which is not shown in the perspective views but is clearly shown in
Figure, 7. The bevil pinion, Q4, has half of its teeth, Q6, chipped away, and to
act in their stend half of an annular disk, Q7, of wood or other material is fixed on
the corresponding part of the friction pulley, Q 5. A nearly horizontal shaft, Q 8,
has its inner end carried by a swivelling eye-stud, Q9, fitted in the bracket, Q3,
and its outer end by a horizontal bar, IQ, through which it passes and which has
one end jointed to the bracket, Q 3, and the other fixed to a vertical rod, 2 Q,
adjustably fixed to a large-horizontal lever, 3 Q. The shaft, Q8, has keyed on it
a small bevil pinion, 4 Q, arranged to gear with the large bevil pinion, Q4, and on
the shaft there is also a small friction pulley, 5 Q, arranged to come in contact with
the half annular disk, Q7, on the large friction pulley, Q5. On the outer end of the
shaft, Q8, there is keyed a small worm-wheel, 6 Q, gearing with a worm, 7Q,
formed on a small shaft, 8 Q, extending parallel to the shaft, L 6, and carried by a
bracket, 9 Q, fixed to the end of the framing, B. On the shaft, 8Q, are slow and
fast pulleys, R, for a driving belt. The small worm-wheel, 6 Q, can be raised out
of and depressed into gear with the worm, 7 Q, by the vertical rod, 2 Q, the upper
end of which is connected to the horizontal lever, 3 Q. This lever, 3 Q, is jointed
to the bracket, M, by a pin, M 1. When it is desired to put the worm wheel, 6 Q,
in gear, a horizontal wooden lever, M 2, which is jointed to a bearing bracket, M 3,
at the front of the machine, is actuated by the worker or attendant and a hoop, M 4,
of iron, or other projection fixed to or it might be formed on it having first
released a small lever catch, M 5, from contact with the under part, F, of
the sliding table, G, the other end of the wooden lever, M 2, bears on and
raises an angular piece, M 6, fixed to the lever, 3 Q. This lever, 3Q, being
raised at the front end depresses the vertical rod, 2 Q, and forces the worm-
wheel, 6 Q, into gear with the worm, 7 Q. As the worm, 7 Q, is always revolving
it actuates the worm-wheel, 6Q, and thereby the small friction pulley, 5Q,
and the small bevil pinion, 4 Q. The bevil pinion, 4 Q, gears with the
large bevil pinion, Q4, and moves the table, G, for a part of its inward and a part
of its outward travel as the bevil pinion, Q4, being stripped of one half of its
teeth, 6, is arranged to act only when the wood is not in contact with the cutter
heads, A, the table being moved for the remainder of its inward and outward travel
by the small friction pulley, 5 Q, which acts on the half annular disk, Q7, on the
large friction pulley, Q5. The arm, Q, is caused to revolve with the pinion, Q4,
and friction wheel, Q5, and raising the weighted lever, L 9, pushes the table, G,
full out and still revolving supports the lever as it descends drawing the table now
steadily in towards the cutter heads, A. When the arm, Q, is describing the bottom
halt of its revolution and is not in contact with the lever, L 9, the wood is being
reduced by the cutter heads, A, until the cams, C2, and, E 3, hear on their
corresponding brackets, C 4. The arm, Q, coming round again raises the lever, L 9,
which pushes the table, G, out and frees the wood from the cutter heads, A. The
small friction pulley, 5 Q, is adjustable along its shaft, Q8, so that the time
the wood is being operated on by the cutter heads, A, can be varied by making the
small pulley, 5Q, act on the large pulley, Q5, farther from or nearer to the centre
of the large pulley.
When the sliding table, G, is full out which happens when the wood for each
hammer handle is being inserted between the centres, C, and, D, to prevent it
moving inward by the action of the weighted lever, L 9, when not wanted I provide
two sets of catches, M 5, and, S. One lever catch, M 5, which is weighted at one
end, and has its other end formed with a gab, M 7, arranged to engage with a
rib, M 8, on the under part, F, of the sliding table, G, is hinged to a bracket, M 9,
on the front of the machine. The other catch, S, has its bottom end fixed on to the

page_text: bracket, 3, and its upper end engaging with a clip, S 1, on the bevil pinion, Q4,
when the pinion tends to come back, the catch, being arranged to pass freely over
the clip when the pinion is revolving towards the front of the machine.
A small angled lever catch, S 2, is provided to keep the lever, 3 Q, raised and
consequently the worm-wheel, 6 Q, in gear with the worm, 7 Q. The catch, S2, is
hinged at the bend in it to an extension of the bracket, M, and has the bottom of
its vertical part formed with a gab, S 3, to engage with the lever, 3 Q. To its
horizontal part, a weight, S 4, is attached and the outer end of this part comes in
contact with a cam-shaped plate, S5, fixed to the under part, F, of the sliding
table, G. The cam-shaped plate, S 5, is formed so that when the sliding table, G,
is out it will raise the end of the catch, S2, and free its gab part from the lever
which can then descend, and when the table begins to go in it will allow the
weight, S4, attached to the catch, S2, to act and make the gab part of the catch
engage with and retain the lever in gear.
In Figures, 9, to, 11, there is shown an improved form of following centre by
means of which short articles can be turned immediately after long articles, in the
same machine, without having to remove any of the main cutter heads, A. The
centre, D, which grips the wood, being shaped, is made with a circular extension, D 2,
which fits and turns in a socket piece, D 3, securely fixed in a sliding part, D4, in
the adjustable following centre bracket, N 8, shown in Figures, 3, and 4. The
centre, D, is held in the socket piece, D 3, so as to turn freely with the wood by a
round pin, D 5, crossing through the socket piece, and engaging with a circum-
ferential groove, D6, in the extension, D2, of the centre. The centre, D, is
arranged near the outside edge of the socket piece, D 3, on the side next the cutter
heads, A, so that when the article is being shaped, the socket piece, and the
bracket, N 8, carrying it, will be amply clear of the cutters, be it a long or a short
article that is being shaped, thus avoiding the disengaging of any of the cutter
heads. The socket piece, D3, might if preferred, be made in one piece with the
centre, D, which could be formed with a round point to allow the wood to turn
freely on it, and be arranged sufficiently eccentric to insure the following centre
bracket, N 8, and parts, clearing the cutter heads, A, when either long or short
articles are being shaped.
Figures, 12, and, 13, show an improved centering guide or device for fixing the
wood concentrically with the centre, C. This guide is arranged on the working
centre, C, and consists of a brass piece, 1C, fitted to work on the centre, which is
elongated to suit it. The brass piece, 1 C, is formed with a circular flange, 2 C, near
its middle and the part of it between the flange and the machine framing, B, is
round and is encircled by a spring, 3 C, which bears on the flange and on the
framing. The part of the piece, 1 C, projecting from the flange, 2 C, towards the
point of the centre, C, is hollow and rectangular in section, the sides of it being
tapered in and towards the flange, 2 C. A clearance space, 4 C, is left between the
brass piece, 1C, and the machine framing, B, when the spring, 3 C, is not
compressed. When the sliding table, G, is full out the bottom of the flange, 2 C,
is just in contact with a cam-shaped plate, 5 C, which is fixed on the framing, B.
Wood being inserted in the hollow part of the brass piece, 1 C, readily becomes
concentric with the centre, C, and as the sliding table, G, goes in the brass piece is
withdrawn from contact with the wood by the action of the cam-shaped piece, 5 C,
on the flange, 2C, the spring, 3 C, reasserting itself and pushing the brass
piece, 1C, out again as the table, G, travels away from the cutter heads, A.
Different sizes of brass pieces, 1 C, can be used corresponding to the size of wood
to be shaped. Figure, 14, shows a modified arrangement of centering devices
provided to enable the worker to centre one piece of wood while another is being
shaped. Vertical bearing brackets, T, are fixed on the upper part, E, of the
sliding table, G, and are formed at their upper parts with an eye through which is
passed a shaft, T 1, having a key seat, T 2, cut in it and extending throughout its
length, aud collars, T 3, being fixed on the ends of the shaft outside of the bearing
brackets. On the shaft, T 1, are two bosses, T 4, and; T 5, the former being keyed

page_text: arm.
to the shaft and the latter being formed with a feather in the eye of it arranged to
fit and slide in the key seat, T2, of the shaft. From the boss, T 4, there project
two arms, T 6, diametrically opposite to each other and in the outer end of each arm
there is a centre, C, arranged to rotate in a bearing, T 7, fixed in the end of the
Each centre, C, is formed with a rectangular extension projecting towards
the framing, B, and arranged to enter a notch hereinafter referred to in the
shaft, N 3, to which the ordinary centre is fixed, when each arm, T 6, is turned
round. The shaft, N 3, with the notch in it causes each centre, C, to rotate when
its. extension is inserted into the notch, the centre thereby forming the ordinary
working centre of the machine. From the other boss, T 5, there project two
similar arms, T 8, each being fitted with the improved device shown in Figures, 9,
to, 11, and a gripping arrangement like that shown on the larger machine the
centres, D, being forced out to grip by teeth, 1 N, on the hand lever, N 4, engaging
with and actuating, when the lever is turned, teeth, 2 N, in the sliding part, D 4,
carrying the centre. The boss, T 5, is fitted to slide along the shaft, T 1, and can
be fixed at any position with a pinching pin, T 9. The arms, T.6, and, T 8, are
arranged so that their respective centres, C, and, D, will be accurately opposed to
each other in the same line. When one pair of centres, C, and, D, hold a piece of
wood which is being shaped the other pair being near the worker, he can easily fix
a piece in them ready to be turned over to be operated on by the cutter heads, A,
when the first is finished. To hold the arms, T 6, and, T 8, in the proper position
when the wood is being shaped, a vertical bracket, 1 T, bolted to and adjustable along
the upper part, E, of the sliding table, G, and formed with a boss, 2T, at its upper
part, through which the shaft, T 1, passes, is provided with a catch, 3 T, fitted with
a small lever, 4 T, which is weighted and causes the catch to enter one of two
recesses, 5 T, formed in the boss, T 5, as the arms are turned over.
To insure the notch in the shaft, N 3, being always in its proper position when
the extension of either of the centres, C, is to enter it I provide mechanism shown
in Figures, 15, to, 17. Figures, 16, and, 17, show the notch, 3 N, in the shaft, N 3.
Fitted on the boss, U, of the bevil pinion, U 1, by means of which the shaft, N 3, is
driven there is a pinion, U 2. Below the pinion, U 2, and fixed to the framing, B,
there is a bracket, U 3, which extends out towards the front of the machine.
Near the end of aud on the bracket, U 3, is a snug, U 4, to which is jointed a
lever, U 5, near its middle part. One part of this lever, U 5, extending towards the
cutters, A, is weighted and resting on the bracket, V, lies nearly horizontal, the other
part extends outwards and upwards and carries in its upper part a small pinion, U 6,
having formed on its side a projecting drum-like part, U 7, with notches, U 8, on
it. On the same spindle, U.9, as the pinion, U 6, is a half of a small toothed
wheel, 1 U, and jointed on the lever, U 5, there is a pawl, 2 J, weighted at its one
end and having its other end engaging with the notches, U 8, on the drum-like
part, U 7. Fixed to the under part, F, of the sliding table, G, is a bracket, 3 U,
one end of which extends outwards towards the front of the machine. The outer
end is formed with a depression, 4 U, on which is a snug, 5 U, projecting upward
and having jointed to it a small catch, 6 U, the other end of which lies on the raised
part of the bracket, 3 U. On the end of the bracket, U 3, and projecting upward
is an eye-stud, 7 U, to which is jointed a circular rod, 8 U, projecting out from the
end of the machine and having formed on its outer end teeth, 9 U, arranged to gear
at a particular time with the half toothed wheel, 1 U. The rod 8 U, is driven by
the pulley, W, and the belt, W 1, and is always in motion. When the part, F,
with the table, G, is fully out the pinion, U 2, gears with the pinion, U 6. When
the table, G, travels in the bracket, 3 U, moves with it and pulls the small
catch, 6 U, which is formed with a tapered point, under a projection, W 2, on the
rod, 8 U, and raises its toothed part into gear with the toothed wheel, 1 U, which
thereupon winds up a weight, W 3, suspended from the drum-like part, U 7,
until the teeth on the rod, 8 U, pass by the edge of the toothed wheel, 1 U, at
which point the winding is stopped, the weight, W 3, being retained at the point to
which it has been wound by the pawl, 2 U, engaging with the notches, U 8, on the

page_text: drum-like part, U 7. The table, G, still travelling in the rod, 8 U, drops over the
catch, 6 U, and the projection, W 2, on it rests on the bracket, 3 U, when the table
begins to come out and the rod is lifted up on the raised part of the bracket again.
The table, G, on coming out causes the pinion, U 2, to gear with the pinion, U 6,
and causes the bracket, 3 U, to release the pawl, 2 U, when the weight, W 3, begins
to act and pulls the pinions, U 2, and U 6, round until a catch, W 4, on the back
of the bevil pinion, U 1, engages with a spring catch, W, placed there for the
purpose, it being arranged when the catch, W 4, and spring catch, W 5, engage
with each other, the notch, 3 N, before referred to, will have been brought to its
proper position for the extension of the centre, C, to enter.
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. The construction and arrangement or combination of parts, constituting the
modification of my improved machinery for shaping wooden handles and the like
