Structures.
I PURCHES MILES, of 204 Madison Street, in the City of Brooklyn, Kings County,
State of New York, United States of America, 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 :-
The object of my invention is to provide a machine for making picket fences and
analogous structures. One such fence is shewn in the Specification of former Letters
Patent granted to me and dated May 1st 1888 No. 6483.
The Invention consists in the details of improvement and the combinations of parts
that will be more fully hereinafter set forth and claimed.

Figure 12 is a face view of the lower part of the dies O P on line ³ ³ figure 7.
Figure 13 is an enlarged detail plan view of part of the picket guide rails, and figure 14
is an edge view thereof.
In the accompanying drawings, the letter A represents the frame of my machine,
which is of suitable construction. B is the main driving shaft of the machine,
which carries a pulley a that is loose on said shaft but which is made rigid therewith
by a suitable clutch mechanism, not shewn. D) is a reciprocating plunger that is
guided in suitable bearings 6 in the frame A, which plunger carries the cutting and
stamping dies, as hereinafter shewn. The plunger D connects by a rod d with an

page_text: eccentric e on the main shaft B whereby said plunger is reciprocated. E is a rock
shaft suitably journaled in bearings in the frame A. The shaft E carries a crank f
that connects by a rod g with an eccentric on the main shaft B, by which means
the shaft E is rocked in its bearings. The shaft E also carries pendent arms i, one of
which arms connects by a rod j with a lever that is loosely hung on a horizontal
shaft m that is journaled in suitable bearings t to on the bed F of the frame A. The
shaft m carries a ratchet wheel n that is engaged by a pawl o carried by the lever
whereby, as the shaft E is rocked, the shaft m will receive intermittent rotary motion.
The shaft m carries one or more rollers p that straddle or pass through a plate q
that is supported by projections on the bed F of the machine. Above the shaft m
is a short shafts that is suitably journaled in the bearings t t in which part the
shaft m is journaled or otherwise carried. The shaft s carries rollers u that are above the
rollers P and that are adapted to contact said rollers p. The rollers p u are the feed
rollers for the sheet metal G. The shafts m, s, are geared together by spur
wheels (see figure 3) whereby, as the shaft m is turned by the lever 1, the shaft s
will also he turned and thereby the feed rollers p u. The sheet of metal G, from
which the pickets A2 are made, is passed into the machine between the rollers
and is fed along by these rollers, as hereinafter shown. w is a tongue or plate that
is placed above the plate 2 and it is carried at one end by a shaft a that is journaled
in the supports or bearings t. The sheet of metal G passes between the plates q w,
and the plate wis kept pressed upon said sheet of metal G by a spring y that surrounds
a guide rod which projects upwardly from upon the plate w and through a cross-
bar a² on the supports or bearings t, said spring y pressing at one end against the
said cross-bar, and at its opposite end against the plate . The sheet metal G is
guided on the plate 9 between upwardly extending ledges 62 at the sides thereof
(see figure 2).
pu
The inner or free end of the plate g is in the form of a female die H (see figures 2
and 5) by which the fingers or prongs on the ends of the pickets A2 (shewn in
figures 10 and 11) are cut. The plate is similarly shaped above the die H and
acts as a stripper. The outer edge d² of the die H (see figure 4) is constructed to
act as a cutter, as presently shewn. Above the female die H, the plunger D carries
a male die I (sec figure 4) that enters said female die and acts in conjunction
therewith to cut the fingers on the sheet metal G that are to be on the ends of the
finished pickets. On the plunger D contiguous to the die I is a male die or punch J
one edge e² of which is adapted to pass close to the edge d² of the die H and in
conjunction therewith to cut off the projecting piece of the sheet metal G after the
fingers have been cut to thereby form the picket A2 as hereinafter shewn. On the
side of the die J opposite to the edge e² is a guard or plate J2 that acts to guide
the cut off picket as said die is moved. The under side of this die J has projections/2
at its ends that are adapted to enter recesses 92 in a female die L that is placed
beneath the die J and on a lower level than the die H (see figure 6). The die J also
has recesses at the side of the projection f2 (see figure 4) while the female die L
has corresponding raised parts 8. As the die J descends, it cuts off a picket from
the metal sheet G projecting from the die H and carries it down on to the female die L
where the projections f² on the die J press the central fingers of the picket down
while the projecting parts 8 press the outer fingers up into the positions clearly
shewn in figure 6. Within the die L are two vertically movable plungers h² (see
figure 6) that are pressed upward by springs in the die L. The upper edges of
these plungers ² are normally above the upper surface of the die L. As the die J
descends, and presses the picket A2 into the die L, said plungers will descend
therewith, but, as said die J ascends, the plungers 2 will follow it and raise the
picket above the upper surface of the die L so that said picket may be carried along
to receive the wires, as hereinafter shewn. 2 are spring plates that are placed at the
ends of the die L, which springs have inwardly extending shoulders that project
in the path of the ends of the picket and thereby limit its vertical movement by the
plungers ² so as to keep the picket after being carried down by the die J below the
level of the die H. Extending longitudinally from the springs and about on a line

page_text: with the top of the plungers 2 when in their upper position, are rails m² that are
secured at their ends near the springs 2 on suitable supports carried by the bed
plate F. These rails m² are straight on their inner edges and taper on their outer
edges towards their free end, as clearly shewn in figure 2. These rails m² are
straddled by, or receive, the fingers of the pickets after they have been struck up or
upset by the dies J L, and guide said pickets as they are drawn along the machine to
receive the wires, as in figure 2.
In order to carry the pickets away from the die L, hooks or fingers o are pivotally
carried on the inner end of a sliding rod n² that is suitably guided on the bed F.
These books o² are pivoted to n², as at p2, and are pressed upon at one end by a
spring that is carried by the rod n² (as clearly shewn in figure 4) so as to keep
their hooked ends above the rod n² in position to engage the pickets. 2 is a
spring plate that is carried by the rod n² and that passes between the hooks o2 and
under the picket, so as to hold said picket in position against the rails m². The
hooks o² are adapted to pass under the die H or into recesses therein (see figure 6)
so as to be in proper position behind a picket, as in figure 4. The outer end of the
rod n² is secured to a sliding head M that is guided on a projecting rail N carried
by the frame A. This sliding head M has, pivotally secured to it at each side,
links that are jointed at their free ends to the arms i that are carried by the rock
shaft E. By this means as the shaft E is rocked, the sliding head M and thereby the
sliding rod n² will be reciprocated. The sliding rod n² also carries feeding hooks t³
situated between the hooks o² and the sliding head M. These hooks t² are pressed
upon at one end by the spring 92 so as to be in the path of a picket A2 as seen in
figure 1. O is a female die that is carried by the bed plate F and is situated between
the sliding head M and the feed hooks t2, the rod n² passing through or beneath it
(see figures 1 and 7.) The feed rod n² carries the pickets from the die H and
places them one by one upon the die O as hereinafter shewn. But said pickets may
be passed to the die O, by other means, if desired.
P is a male die that is carried by the plunger D, above the die O (see figure 1).
These dies are adapted to press or stamp the picket A2 when placed between them
and are of the shape shewn in figure 7, whereby the picket when pressed by them
is corrugated or grooved longitudinally. These dies also have one or more cross-
grooves for receiving and pressing the metal plate about the wire to form a cross
groove in said plate (see figure 12) and thereby to securely hold the picket on the wire.
The cross-grooves in the dies O P, should be undulating that is to say, should
follow the cross-surface of the longitudinally grooved dies. By this means the picket
or plate is given an undulating or waving cross groove. By this means great strength
and stiffness are given to a thin metal picket or plate. But, instead of placing a
groove in the die, said die may have projections or other means to press up the metal
of the picket, contiguous to the wire. The male die P carries on one side two cam-
like projections 2 (see figure 12) that are adapted to engage the wires to be secured
to the pickets and to press said wires firmly against the ends of the picket between the
fingers (see figure 10) as said die P descends. Upon the sliding head M is placed a
block w² that has a longitudinal groove adapted to receive a grooved part of the
picket. This block w² carries spring pressed hooks a² that are adapted to engage a
picket when placed upon said block, to assist it holding it thereon. Qis a swinging
tongue that is pivotally carried by the head M above the block 2 and it is adapted
to bear at its free end upon the block 2 or upon a picket thereon, to hold said picket
in position on the block.
Having now shewn how the sheet metal G is fed into the machine, the fingers cut
therein for the pickets, the picket cut from the sheet and its fingers struck up; also
the feed mechanism for carrying said pickets along, and the die for corrugating or
crimping said pickets, I will now shew how the wire is led into the machine and placed
into position on the pickets.
The wire B2 for the pickets, is fed into the machine from each side through
straightening rolls R of any suitable construction (see figure 3). The wires then pass
on each side along a post or other contact piece a and against discs or rollers 6 et

page_text: and e, said rollers being so arranged as to guide the wire about parallel along the
inclined edge of the rails m² and in the plane of motion of the plate or picket A².
But the rollers et could be replaced by stationary or other guides, if desired. From
the rollers the wires pass in a straight line or in the longitudinal axis of the
machine through the sliding head M. The rollers et are placed just in advance of the
free ends of the guide rails m², their inner edges being about on a line with the inner
edge of said guide rails (see figure 2). As the pickets A2 are carried along by the
feed hooks t² on the sliding rod n², the fingers on said pickets will embrace the rollers et
and thereby the wires that are guided by said rollers will be passed in between said
fingers and laid against the body part of the picket ready to be pressed or woven
together by the lies O P, as hereinafter shewn. Thus the plate or picket is deposited
on the wire. The supporting rods or axles of the rollers et are connected by a
bar that passes over the wires B2 and over the sliding rod n². This cross-bar g
carries rollers that are adapted to bear upon the surface of the rollers e* and to
press down the fingers of the picket that pass over said rollers et.
(see figure 1) are rollers similar to 4 that are journaled in supports on the bed
plate F and that bear on the under side of the rollers et for the same purpose as the
rollers *
The sheet metal G when fed into the machine and before it reaches the feed
rollers pu, is passed through a guide head S that is carried by the bed plate F. In
the guide head S is placed a vertically movable plunger that carries a knife T that,
in conjunction with a knife T2 on the frame A, is adapted to cut off the sheet metal G.
The distance between the knife T and the edge d² of the die H is calculated to be the
width of a certain number of pickets, so that when the outer end of a strip of sheet
metal G has about reached said knife the metal may be cut off so that only the
required quantity of metal will be passed by the feed rollers to the dies. The knife T
is reciprocated as follows:-To the plunger j is secured a pendent rod that is jointed
to a treadle m carried by the frame A. This treadle, and thereby the knife T, is
elevated by a spring n secured to said treadle and to a suitable part of the frame.
In order that the machine may be stopped when the end of a metal sheet G has about
reached the knife T, the following device is provided:-U (see figure 3) is an arm
that is pivoted to the frame A and that is adapted to engage the clutch of the pulley a.
The shaft of of this arm U is provided with a crank p* (see figure 1) that is connected
by a rod q with a treadle suitably supported. The treadle is held down so as to
throw the arm U out of contact with the clutch on the pulley a so that said pulley
will rotate the shaft B by means of a latch s pivoted at t through which the treadle
passes (see figure 9). To the latch s¹ is secured an arm u which, when being pressed
upon by the operator, releases the treadle thereby permitting it to be raised by a
spring secured to said treadle and to the frame A. As said treadle thus rises, the
arm U will be thrown to disengage the clutch on the pulley a. The latch carries a
stud or pin that passes through a slot in the end of a rod at that passes upwards
and is secured to a lever y that is pivoted in the guide head S. A spiral spring
surrounding the rod and pressing against a shoulder thereon and against the
frame A, tends to lower the same. The downwardly projecting end of the lever y¹ is
adapted to pass downward through an opening in the guide head S, but is held in the
upward position by resting upon the sheet metal plate G from which the pickets are
made. When the end of the sheet metal G passes from under the end of the lever y
said lever will descend through the action of the spring thereby moving the latch s
out of contact with the treadle whereby said treadle will be elevated and the
clutch on the pulley a engaged by the arm U, thereby automatically stopping the
machine.
Having now described my improved fence-making machine, I will shew how it
operates in making a fence :
Suppose the sheet metal strip G to have been fed into the machine until its end is
flush with the edge of the die H; the dies 1, J, and P, to be in the partially
elevated position shewn in figures 1 and 4, the die 1 to have cut the fingers at the
edge of the metal sheet thereunder, and the feed hooks o² to be in the position shewn

page_text: in figure 4. The machine is now started by rotating the shaft B. As said shaft
rotates, it will act to elevate the dies carried by the plunger D, at the same time acting
through the rock shaft E the rod j and lever l shaft m and rollers u to feed the sheet
metal from the die H and under the die J while at the same time the rod n² advances
under the influence of the arms i on the shaft E acting on the sliding head M.
While the plunger is at its highest point and until it begins to descend, the sheet
metal is still fed forward the feeding rod n² being also moved forward. When about
half the width of a picket has been fed from the edge 2 of the die H, the plunger
carrying the dies will begin to descend. As said plunger descends, the picket
continues to be fed forward as is also the feeding rod n². By the time the sheet metal
has been fed from the edge d² for the width of a picket, it will cease to be fed, the
feeding rod n² also completing its forward stroke, while the plunger carrying the dies
will descend and cut off the projecting piece of sheet metal G, the die J acting with
the edge d² for this purpose. As the die J acts to cut off the metal as above, the die I
acts to punch out the fingers on the part of the sheet metal G next behind the picket
just cut. The die J stili continuing to descend after having cut off the picket, carries
the picket just cut down on to the die L thereby depressing the plungers h². As
the die J carries the picket down on to the die L, as above, it acts with said die L to
strike up the fingers of the picket, as before shewn, so that they shall stand at an
angle to the body part of the picket, as in figure 1.
While the die J is in this, its
lowest, position the feed rod n² with its head M begins to return and as said die J
then rises and releases the picket leaving it on the die L and plungers 2, the hooks o²
on the rod n² will pass under said picket. As said die J continues to rise and when it
reaches the partially elevated position shewn in figure 4, the hooks o² will have passed
behind said pickets, as shewn in said figure. From this point as the plunger Dagain
rises as heretofore shewn, the feed rod n² again advances and, by means of its hooks,
carries the picket along the rails m² towards the dies O P, the feed rollers p u at the
same time again feeding forward the sheet metal. When the feed rod n² has reached
its full forward stroke and begins to recede while the dies are making another picket,
the hooks o will leave the picket A2 just moved forward on the rails m², the lugs m
(see figure 14) on said rails preventing the picket returning. As said feed rod n²
returns to take another picket from the die I, the hooks t2 on the feed rod n² will
engage the picket just left by the hooks o² while the hooks o² engage another picket
on the die L and as said feed rod n² is again moved forward the hooks T2 will carry
the picket that has been retained by the lugs me along between the rollers et which
rollers will lay the wires between the fingers on said latter picket. As the feed rod n?
continues to advance, the picket pushed by the hooks t2 will be laid upon the female
die O while the hooks o bring the other picket from the die L and when the plunger
again descends with its dies I J to cut out the fingers, cut off the picket and strike up
the fingers of another picket as heretofore shewn, the die P and the plunger, will act
on the picket just laid on the lower die O to corrugate it and at the same time by the
cams to press the wires against the inner ends of the fingers, the cross-grooves in
the dies OP pressing the metal of the plate about the wires thereby forming
cross-grooves in the plate or fingers, the wires being themselves curved to follow the
cross-corrugations of the picket. After the first picket has been thus corrugated and
fastened upon the wires, said picket is drawn forward-say by hand-the distance
that the pickets will be apart on the wires. When the feed rod n² reaches its extreme
inward position again the block w² will pass beneath the picket just drawn forward,
the tongue and the hooks a² then engaging the picket upon the block w² thereby
locking the picket to said block. As the feed rod n² next advances after another
picket has been made, the tongue Q with the block w² and the hooks a² will act to
draw forward the wires and pickets.
I have now shewn how the first picket, when starting the machine, has been made
and secured to the wires and placed upon the block w² to act to feed forward the wires.
Each time the feeding rod n² now moves forward after a picket has been made and
while the plunger is moving up and down, it will draw a supply of wire through the
straightening rolls R by the tongue Q engaging and holding a picket on the block w²,

page_text: in conjunction with the hooks. Each time a picket is cut off and struck up by the
dies JL, it will be carried away by the feed rod n² and passes along the rails m² to
receive the wire between its fingers from the rollers e, while each time the plunger
descends, its dies will cut out the fingers, form a picket and, when upon the die O,
corrugate it. groove it crosswise, and secure it to the wires. As long as the machine
is supplied with sheet metal strips G and wires, it will continuously act to make a
picket and place it upon the wires at the desired distance apart. When the end of
the sheet metal strip G has reached and passed from under the lever y* said lever will
descend and throw the clutch to stop the machine. To again start the machine, it is
only necessary to depress the treadle to again permit the clutch to act.
In figure 10, is shewn a picket that has a wire at both ends, but said picket may
have a single wire, as shewn in figure 11, if desired. By cutting the picket shewn in
figure 10 between the wires, the picket attached to a single wire and shewn in figure 11
may be made.
Although 1 have shewn a strip of metal G of a width to produce the proper length
of picket and that is cut into the proper widths for the pickets in the machine, it is
evident that pieces of metal of the proper length and width may be placed directly on
the die H by suitable means. Also that the strips of metal of the proper width for
the pickets may be placed directly on the die H and cut off to the proper length for
the pickets, instead of cutting them to the proper width, as shewn in the drawings.
In the above cases, the feed rollers pu may be dispensed with, or otherwise suitably
arranged.
For some styles of pickets it may not be necessary to corrugate them through their
entire length, but they may have other desired shapes. By making the dies O P, of
suitable form, the shape of the finished picket may be determined.
In addition to making fences, as herein shewn, my improved machine may be used
for attaching sheet metal, or other material, to wires, rods, or strips, for other
purposes; and the term picket herein used is intended to cover such other pieces as
may be used.
