WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN PEGGING MACHINERY, AND
IN WIRE PEGS TO BE USED IN THE MANUFACTURE OF BOOTS AND SHOES." A
communication from abroad by Oscar Le Grand Noble, of Chelsea, Michigan,
and Treat Timothy Prosser, of Chicago, Illinois, both in the United States of
America.
This Invention relates to pegging machines which supply themselves with pegs
by cutting them successively as needed from a coil of wire, and in which the boots
or shoes are presented to the action of the pegger in an unlasted condition upon an
anvil support, which is adapted to enter all the varying sizes, and is so organized
that the unlasted boot or shoe can be fed over it under the peg driver along the
line of the contemplated seam.
The improvements in this machinery consist-
First. In novel means for supporting and feeding the boot or shoe.
Second. In mechanism for periodically forcing the pegging head toward the anvil
support for the purpose of compressing the boot or shoe bottom each time a peg is
being driven.
Third. In mechanism which causes the machine to automatically change the
extent of the wire feed in response to the variations in the thickness of the stock
under operation, so as to cut each peg of the exact length required, and without
waste.
Fourth. In certain devices for guiding and cutting the wire, and also for nicking
it when the pegs are to be clinched.
..

page_text: Fifth. In certain details of construction herein-after fully described.
The clinching pegs made in this machine are also of novel construction, adopted
with a view of facilitating the clinching operation as well as to obtain a better
clinch.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a perspective view of one form of the said improved machine;
Figure 2 is a longitudinal section of the upper portion thereof; Figures 3 to 9
represent in detail various parts of the same. The remaining Figures are herein-
after described. Similar letters indicate the same parts throughout the Drawings.
The stand or frame A provided on the top with forwardly projecting cheek plates
carries all the working parts of the machine, the majority of which derive their
motions from the continuously revolving driving shaft B, which is arranged in
bearings in the rear ends of the cheek plates transversely across the machine. The
pegging head C is secured in an upright position to the forward forked end of a
massive arm or helve C¹, which being pivoted at its rear end upon the driving shaft
is snugly fitted between the check plates of the stand, so that it will be supported
thereby against lateral strains. The extreme lower end of the pegging head
consists of a nozzle c, which will be termed the presser foot, because it rests and
presses on the bottom of the boot or shoe supported directly under it
the tip
upon
of the fixed horn D. A disc E is fixed upon the driving shaft, having in its inner
face a cam groove 1, which engages an antifriction roller on the laterally pro-
jecting stud e of a lever E², which extending forward is fulcrumed at e¹ on the
exterior side of the cheek plate. The outer arm of this lever is connected by a link
E to one end of a U shaped bar or strap E, the horizontally projecting legs of
which are pivoted on a shaft E on either side of a friction disc E, which is firmly
secured on said shaft. The helve of the pegging head is provided with a cogged
segment C, which gears with a pinion E7 keyed on shaft E. The strap E carries
a pivoted pawl E³, the end of which is shaped to match the surface of the edge of
the friction disc Es, and is borne up by a spring E tending to throw it against the
said disc. A set screw E10 carried in a nut projecting from the check plate
determines the upward throw of the free end of the friction pawl. By means of
the cam groove E¹, the form of which is clearly shown in Figure 9, the forward
arm of lever E2 is depressed at a certain time in the rotation of the cam disc E,
causing the pawl Es to engage the friction disc Es, and to impart to it a partial
turn in the direction of the arrow, as marked in Figures 1, 2, and 9. The shaft E°
being thus turned its pinion E acts on the cogged segment C2 and draws the helve
of the pegging head down, so that the boot or shoe bottom will be tightly com-
pressed between the anvil of the horn and the presser foot of the pegging head.
The compression continues until a peg has been driven, when the cam groove
returns the lever E to its normal position, whereby the free end of the friction
pawl is brought up against the set screw E10 relieving the friction disc.
degree of compression can be readily governed by adjusting the set screw E10, 80
that the pawl will engage the friction disc sooner or later during the down stroko
of the outer arm of lever E. A hand lever shown in dotted lines in Figure 2 is
secured to one end of shaft E for convenience in turning it to raise the pegging
hend if desired. A stout spring C³ is provided on the stand under the helve of the
pegging head, as shown in Figure 2, as an elastic support, which will prevent the
presser foot from descending upon the horn when there is no boot or shoe upon it,
and will at the same time be sufficiently yielding to the action of the above
described compressing mechanism, to prevent any damage to the machine should
it, be accidently started at such a time. The pegging head will be counterbalanced
usually in the manner illustrated in Figure 1, so that it will only lightly bear down
on the stock under operation on the horn.
The
A walking beam 1ª is mounted on a stout standard 0 of the helve of the pegging
head. It receives an oscillating motion from the driving shaft B through the
medium of an excentric F¹ and rod, and its long arm reaches into the open frame or

page_text: sash formed on the pegging head. The excentric rod consists of two parts
connected by a screw coupling F2, by "means of which it may be adjusted
in length for properly regulating the throw or position of the walking beamn
with reference to the extreme end of the presser foot. The long arm of the
walking beam is connected by links Fs to the cross head G² on the stem G³ of the
peg driver G, and imparts to the latter an up and down motion in the pegging head.
The stem of the peg driver is at its lower end fitted in an aperture in the solid
part of the pegging head, while its upper end slides or moves through a box in the
top of the sash thereof. The peg driver G is a thin steel rod adapted to operate in
the wire and nail tubes of the pegging head. The wire tube c' is above the shears
for cutting off pegs from the wire, and the peg or nail tube c² of which the presser
foot c constitutes a continuation is below such shears, but they remain all permanently
in line. The wire from which the pegs are to be cut is fed by the feed rolls H and H¹
through an oblique channel c³, of the wire tube c' which channel opens some distance
below the top of the wire tube into the aperture in which the peg driver plays,
but continues down to the bottom of the tube so that the wire can retreat into it
during the descent of the peg-driver into the peg tube and presser foot as shown in
Figure 2. The aperture in the peg tubo is flaring on top so as to insure the
entrance of the wire should it feed slightly out of live. The small feed roll H³ is
carried on one arm of a lever H pivoted at h between the jaws of the helve C¹,
where the feed rolls are also located. The other arm of this lever carries a set
screw which bears on a spring 3 on the helve. The stress of the spring causes
the feed roll H¹ to be forced by the lever H2 towards the feed roll H so that the
wire will be firmly held between them. The feed roll H is fixed on the shaft H³,
which has its bearings in the jaws of the helve, and carries on its overhung end a
fixed ratchet wheel H, see Figures 3, 4, and 5. The ratchet wheel H' is encircled
by a cap H which turns loosely on shaft H³, and is secured to the pinion H, which
also turns loosely on said shaft and meshes into a segmental rack H fixed on the
adjacent check plate of the stand, as shown in Figure 1. On opposite sides portions
of the rim of the cap H are cut away, as shown at h³, h³, Figure 3, to expose the
teeth of the ratchet wheel H' at those points. A plate H³ is centrally pivoted upon
shaft H between the ratchet wheel and the side of the helve C¹, and is
connected by a rod H to the walking beam F so that the plate will receive an
oscillating motion from said walking beam. The teeth of the ratchet wheel are
engaged through the openings in the rim of cap H5 by two pairs of pawls l' and h5,
and and respectively pivoted to the plate HB on opposite sides of the ratchet
wheel in the manner clearly shown in Figure 3. In the present instance the
numbers of each pair are arranged side by side, one being longer than its fellow by
nearly one quarter of the distance between two adjacent teeth of the ratchet wheel,
and the pairs are disposed relatively, as best shewn in Figure 5, so that only one
pawl will actually engage a tooth of the ratchet wheel at a time, while the other
three simply ride on the back of the respective teeth. Each pawl has an angular
arm drawn upon by a spring 8 to throw the point of the pawl toward the ratchet
wheel. It will be understood that as the pawis can reach the ratchet wheel to act
on it only through the openings in the rim of cap H³ the extent of the motion of
the ratchet wheel, and consequently the extent of the feed, will be governed by the
position of said openings with relation to the stroke of the pawls. The cap H³ is
adjustably secured to the pinion H by clamping screws passing through slots in
the pinion into taps in the cap, whereby a primary adjustment of the cap can be
effected. This primary adjustment is provided for in order that the wire feed may
be set to either equal the thickness of the stock under operation when the pegs will
not be clinched, or to exceed it more or less when the pegs will be clinched on the
inside of the stock. The cap is so disposed that the solid portions of its rim will
keep the pawls from the ratchet wheel, except during the latter portion of the
upstroke of rod H, when the pawls turn the ratchet wheel and a corresponding
portion at the beginning of the downstroke of the said rod when they simply ride
over the ratchet wheel. After the primary adjustment of the cap its position is

page_text: governed automatically by the greater or less elevation of the pegging head, for as
this changes its position in response to the varying thickness of the stock moved on
the horn under its presser foot it will cause a corresponding motion to be given to
the pinion H by the stationary rack H. Thus when tho pegging head is resting
with its presser foot upon a thin portion of the stock the openings in the cap E³
will be so disposed that the paws can give only a proportionately short turn to the
ratchet wheel. Then in feeding a thicker portion of the stock under the pressor
foot the pegging head rises and the cap H³ is turned correspondingly, so that the
pawls will engage the ratchet wheel sooner and consequently give it a greater turn.
The gearing is so proportioned that a change in the thickness of the stock will cause an
exactly corresponding change in the length of the feed, so that the length of the
pegs will be proportionate always to the thickness of such stock. By the use of
multiple pawls arranged as stated quite minute changes in the feed can be effected
with a ratchet wheel comparatively coarse toothed, which is quite important, since
a fine toothed ratchet wheel and correspondingly slender pawls will not stand the
wear any length of time. The end of the wire leading from the feed rolls through
the lateral channel of the wire tube c¹ passes through an eye in the end of a
guide rod I, which is seated in a horizontal way in the side of a slide bar K, which
is in turn arranged in guides in the under side of the helve C¹. A laterally projecting
stud and antifriction roller on the rear end of guide rod I enter a cam groove L' in
the cam disc L on the driving shaft B. This cam groove L' will give a slight end-
wise motion to the guide rod I causing it to hold the wire back in the channel c³ of
the wire tube during a portion of the rotation of the driving shaft, while during the
remainder of the rotation it will hold the wire advanced so that its end will be directly
over the mouth of the peg tube. The cam groove L³ is so timed with reference to
the excentric F¹ that it will advance the guide rod a little after the lower end of
the peg driver has passed it on its up stroke and just before the wire feed begins,
and withdraws it again shortly after the wire has been fed and a peg cut from it.
The slide bar K has near its rear end a lateral stud and antifriction roller entering
the cam groove L in the disc L, which imparts to it a compound reciprocating
motion, as will be presently explained. Its forward end is located between the
shear levers M, M, as best seen in Figure 6, and is provided with cam surfaces /
and I, which act on the rear ends of the shear levers, causing their blades m, m³,
to approach each other to cut the wire during the retreating movement of the slide
bar. The shear levers are pivoted on the respective jaws of the helve C¹ so that
their blades will operate as close to the lower end of the wire tube c¹ is practicable.
Their pivot pins are connected by a yoke M² for the sake of strength as well as for
maintaining the relative positions of the shear levers. Their rear ends are coupled
together by a spiral spring M³, which will open the blades the moment the
levers are released from the cam surfaces k and k¹. A bar K¹ is secured in the end
of the slide bar K and directly under the guide rod I. Its forward end is reduced
in thickness, as seen best in dotted lines in Figure 6, and is intended to enter a
slit in the rear side and at the lower end of the wire tube. Its front edge has a
slight projection or bit ³, best shown in Figure 7, which is intended to press an
indentation in the wire just above the point where the shears cut it for the purpose
of facilitating the clinching of the pegs. The shear blades are adjustably connected
to the levers in the manner clearly shewn in Figure 6, and they are so formed as
to press a V-shaped point on the end of the wire in cutting a peg from it. The
indenter K¹ is adjustably connected to the end of slide bar K, as shown in Figure 6,
so that it can be projected more or less according as it may be required to make a
deepor or shallower impression on the wire, or not to operate at all thereon. The
cam groove L has such a configuration and is so timed with reference to the
excentric F¹ and the cam groove L₁ that it will immediately after the wire feed
has has been completed draw the slide bar K back to close the shears and sever a
peg from the wire, then advance it again a little beyond its normal position for
making an impression on the wire by the indenter, and then withdraw it to its
normal position just before the wire guide rod I is withdrawn. The boot or shoe

page_text: is moved along on the horn by means of a sharp pointed feed lever N, the vertical
arm of which is opposite to the flattened side of the presser foot c, so that its point n
can operate close up to the line where the peg is driven. Its obliquely extending
arm is at its extreme end pivoted to the slide bar N¹, to which it is also connected
by a spring n', which permits it to yield so as not to operate on the stock in the
back stroke. The slide bar N¹ is arranged diametrically across a horizontally
rotatable frame or bowl N³, the hub of which encircles the hub et at the lower end
of the pegging head, as shown in Figures 2 and 8, and which is held in position on
said hub by the flange on the lower end of the peg tube c². The presser foot c
is secured to the bottom of bowl N2, so as to rotate with it and always maintain the
same relative position with reference to the feed lever N. The slide bar N¹, which
straddles the hub of bowl N2 by an oblong central aperture is moved back and
forth through slots in the sides of the bowl by a vertically reciprocating ring N³,
which is snugly fitted between the oblique shoulders n², n², of the slide bar. The
ring NS is secured to the lower end of a bar N seated in a way in the front
side of the pegging head and held in position by caps n³, n³. The upper
end of bar N is connected to the link No by a pitman N, whose point of con-
nection with the link is made adjustable by means of a slot n in said link, so that
the stroke of the pitman can be regulated to give any desired stroke to the feed
lever N. The link N is pivoted at n³ to the pegging. head, and has an angular
slot no, in which an antifriction roller n' on the cross head of the peg driver plays
up and down, giving an oscillating movement to the link. The lower end of slot no
is so disposed that the play of roller n' in it will have no effect on the link. The
lever N feeds during the up-stroke of the peg driver, but by reason of the peculiar
arrangement of the lower end of slot no it does not begin to feed until the peg
driver bas risen some little distance from its lowest position, so that the boot or
shoe may first be relieved from the action of the compressing mechanism. A flango
ns is bolted on the bowl N* above the slide bar N₁ to prevent the latter from rising
under the action of the reciprocating ring N³.
The operation of this machine will be readily understood from the foregoing
description by any one skilled in the art; but it may not be out of place to
give a brief suminary thereof at this point. The boot or shoe to be pegged is
slipped on the horn D, with the toe pointing toward the operator sitting or standing
in front of the machine, in case the horn is arranged as shown in Figure 1. The
shoe or boot will be so held that the anvil tip of the horn may support it on one
side as near to the heel as practicable, and the bowl N will be turned so as to
bring the feed lever N to the front side of the machine in beginning the pegging
operation. Assuming that the wire feed was arranged for pegs to be clinched, and
that the first peg has been just driven home, the peg driver will begin its ascent.
Almost at the same instant the stock will be relieved from compression, and imme-
diately theroafter the boot or shoe will be fed along the required distance between
two pegs, raising or lowering the pegging head if any change in the thickness of the
hoot or shoe bottom occurs, which will cause a corresponding change in the position
of the openings in cap H, which govern the wire feed. After the lower end of the
peg driver has in its ascent reached a point a little above the wire guide rod 1,
the latter advances with the end of the wire, so as to arrange it in line with the peg
tube c. Immediately thereafter the wire is fed down, and when the feed has been
completed the shears cut a peg from the wire, the peg dropping through the peg
tube into the presser foot, which holds it in an upright position, resting with its
pointed end on the stock ready to be driven into it. After the shears have cut a
peg from the wire the indenter K¹ advances and presses a nick in the wire near
the point, withdrawing at once to permit the wire guide rod to retreat also, and
draw the wire back out of the path of the peg driver, which is now again descending.
The pegging head is now forced down to compress the stock by the cam groove in
disc E and the described intermediate mechanisın, and is held down while the peg
driver forces the peg into the stock. The lower end of of the peg will strike the
anvil tip of the horn and clinch forward the nick near its point. The feed lever N
is also moved over the stock during the descent of the peg driver the determined

page_text: distance in preparation for another feed. As the pegging continues the boot or
shoe is fed along on the horn without any considerable change in the position of
the fced lever until the anvil tip reaches the toe when the bowl N2 is turned so as
to swing the feed lever around to the side of the machine to enable it to feed the toe
across the horn. When the horn reaches the other corner of the toe the bowl is again
turned, so as to swing the feed lever around to a point about opposite to the point
of starting, when it will feed the boot or shoe off the horn until the heel is reached.
It is immaterial whether the indenter makes an impression on the wire or not
when the wire feed is so arranged that the peg will not be cut long enough for
clinching. Smooth wire may be employed with excellent results, but I prefor
wire provided with minute indentations all over its surface, which feature greatly
increases the holding power of the pegs cut from it.
The machine so far described operates with a stationary anvil support for the
boot or shoe, and a shiftable feed lever for properly moving the boot or shoe along
on its anvil support. But as some manufacturers or operators may prefer to use
a machine in which the boot or shoe feed mechanism is localized on the pegging
head, and the anvil support adapted to move with the boot or shoe on it in such a
manner that the lever can feed the stock along the line of the proposed seam, I
have provided for the ready removal of the pegging head C from its helve, and the
substitution therefor of a pegging head O, as well as for substituting a suitably
shiftable anvil support for the stationary horn D. The pegging head O, illustrated in
Figures 11 and 12, can be applied without requiring any changes in the disposition of
the other parts of the machine, except that the excentric rod for driving the walking
beam F will have to be somewhat shortened to change the stroke of the peg driver,
since in this pegging head the distance from the shears to the extremity of the
presser foot is less than in the pegging head C. The feed lever o of pegging head O
is pivoted at o¹ to the lower end of the lever O¹, which is pivoted on the front side
of the pegging head at o, and has an angular slot in its upper arm as shown, to be
oscillated from the cross head of the peg driver in manner like link No of pegging
head C. The arm o" of the feed lever is located under a projection of on lever O¹
against which it is drawn up by the spring ob. A bracket O secured upon the side
of the pegging head carries a bar 0%, the lower edge of which is provided with a
projection o". This bar O is mounted by means of stud pins in a curried slot 07 on
the bracket, and can be adjusted by means of a set screw O*, which is carried on a
swivelling eye bolt on the bracket and works in a swivelling nut 08 on the upper
stud pin of bar O". The slot 07 is curved over tho fulcrum o² of lever O' as the
centre. The length of the feed of lever o is governed by the position of the pro-
jection o" in the following manner :-On the back stroke of lever O' the end of arm
o of feed lever o will ride up on the projection o" so as to lift the point of the feed
lever off the sole against the stress of spring o³, and it is thus kept off the sole on
the forward stroke of lever O¹ until the end of arm o³ is released from projection o",
when spring o immediately draws it up against projection o' on lever O' throwing
the point into the sole when the feed of the boot or shoe begins. Of course by
shifting bar 03 with projection oº up or down the extent of the feed of the boot or
shoo at each forward stroke of lever O' can be readily regulated. In connection
with pegging head OI prefer to use either the anvil support shown in Figure 10, or
the rotating horn shown in Figure 13. The anvil support illustrated in sectional
elevation in Figure 10, consists of a straight column P, adjustably supported on a
prop or bearing P¹, and a self-adjusting solid anvil plate På hung to the top of the
column. The head of the prop P¹ is circular, and is concaved on its upper side.
The column P has a circular base convex on its under side, which is snugly fitted in
the concaved head of the prop P¹, and is adapted to move therein like a ball in a
socket. The column terminates in a spherical head p, the centre of which is
coincident with the centre of its spherical base, and to which the anvil plate P² is
permanently jointed by means of its socket p¹. This support is to be secured to
the base plate of the stand A. in such a manner that the centre of the head 2 of the
column P will be in line with the peg driver. In pegging around the sole of a boot
or shoe with pegging head O, the column P requires to be adjusted by the operator

page_text: from a vertical to inclined positions in various directions to permit it to reach into
the toe and to properly co-operate with the feed lever o. These adjustments will in
no wise affect the anvil plate P³, because the pivoted point on which the column
moves, namely, the centre of its head p, is also the centre of rotation of the anvil
plate, so that the latter is free to preserve its horizontality, and to measurably
accomodate itself to the surface contour of the insole of the stock upon it while the
head of the column moves in its socket p¹. The pegging head being forcibly pressed
down on the stock each time a peg is inserted will of course hold the anvil plate
steady during the driving of the peg, so that it will then act as though it were
fixed on the column, and properly perforin the function of a clinching anvil when
the pegs are to be clinched. The anvil plate is circular, and being free to rotate on
the head p of the column will greatly facilitate the feeding of the stock by lessening
the friction. It will be made of a necessarily small compass. The base of the
column is a somewhat greater segment than the concavity of its supporting pedestal,
so that it will project all around when the column stands vertically. This in con-
nection with an internal circumferential flango will afford a good hold to the
operator in adjusting it. This base is also of such dimensions that at the greatest
required inclination of the column the line of the pressure by the peg driver will
still fall within the compass of such base. Antifriction balls may be introduced
under the base of the column for greater case of movement.
The revolving horn shown in Figure 13 consists of a frame R and a beak R¹,
which is supported in the socket of the frame with its vertical stem. The
frame is to be centrally pivoted on a suitable stem on the base plate of stand A,
so that its centre of rotation will be in line with the axis of the peg driver or
thereabouts. The anvil tip of the beak when in working position will stand.
vertically over the axis of the frame. The beak can be turned in its socket to
swing it around from under the pegging head; but it is provided with a spring
catch 8, which engages a groove 8¹ in socket 1, whenever the beak is swung into
position under the pegging head, and holds the beak firmly in position. The
frame R is extended beyond its axial hub r, and at its other extreme end provided
with a handle, and its bulk is so disposed that as a whole the horn will be
balanced on its axis of rotation. The frame R of the horn may be made of cast
iron, and the beak R¹ only of wrought iron, with a suitable steel tip for an anvil
surface. The beak is made of the angular form shown, to conform measurably to
the shape of a boot.
Figure 14 illustrates a portion of a seam in which the pegs are not clinched,
and Figure 15 a seam with clinched pegs, in both instances exposing the pegs as
they are imbedded in the leather.
The pegs made on our machine, when the indenter operates on the wire, have
the forin clearly shown in Figure 16. They have a chisel-edged point, and a
shallow notch directly above the point, extending across the peg at right angles
to its chisel edge. The side of the peg containing the notch is also a little longer
than the opposite side, so that the chisel edge will stand a little obliquely to the
axis of the peg.
The advantages of this peculiar construction may be briefly stated as follows:-
Were the chisel edge square with the axis of the peg or nail it would necessitate
the use of a notch deep enough to extend beyond the axis of the peg to cause
the desired clinch, for were the notch in that case less deep, the point of the
peg on striking the anvil would merely upset and not clinch. But by making the
chisel edge a little oblique with the longest corner directly under the notch,
the clinching can be effected with certainty and with little force by the use of n
comparatively shallow notch, which will not materially weaken the point so that
it will not bend before it strikes the anvil, as it would be liable to do did the
notch extend beyond the axis of the peg: Of course the point will bend over
towards the notch in clinching, and it is desirable that it should bury itself in
the insole. This is greatly facilitated by arranging the notch transversely to the
chisel edge, because in this way the point in clinching presents one of its side

page_text: edges to the insole, which is of course more readily entered by the side edge
than it could be by the flat side of the point.
It will be understood that the elongation of one side of the peg is caused by
the action of the indenter in pressing the notch into the wire, as the metal must
necessarily slightly elongate. This effect is made more certain by the form of the
bit of the indenter.
I would remark that the pegging head C may be used with either of the anvil
supports, respectively illustrated in Figures 10 and 13, in which case the operator
would have the advantage of both a rotatable feed mechanism and a shiftable
anvil support for properly moving the boot or shoe along on its support.
Having thus fully described the said Invention as communicated to me by my
foreign correspondents, and the manner of performing the same, I wish it understood
that I claim the improvements herein specified as shewn and described and for
the purposes set forth, that is to say-
The mechanism specified for periodically compressing the boot or shoe bottom
between the pegging head and the anvil support.
Also the rotatable feed mechanism for feeding the boot or shoe around a localized
anvil support.
Also the mechanism for feeding the wire variability, according to the varying
thickness of the boot or shoe bottom under operation.
Also the guide for laterally alternately advancing and withdrawing the end of
the wire with reference to the path of the peg driver.
Also the mechanism for cutting and indenting the wire.
Also the pegging head O adapted to be substituted for the pegging head C when
the machine is provided with a shiftable anvil support.
Also the anvil support shown in Figure 10.
Also the balanced rotating horn shown in Figure 13.
Also the peg shown in Figure 16.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Fourteenth day of March, in the year of our Lord One
thousand eight hundred and seventy-six.
