page_text: In the upper part of the frame A of tho machine, the shaft A' is journaled and on
the same, the discs B and B are mounted eccentrically on the front and back of the
machine respectively, which discs are surrounded by straps or bands connected with
rods. At the front of the machine, the rod B2 is connected with the eccentric, and to
the lower end of said rod B² the reciprocating cross-piece or hammer C is pivoted
which is guided between the guides C on the front of the machine. To the said
cross-piece or hammer C, the upper die is fastened which will be described herein-
after.
On the rear end of the machine, the rod B is connected with the strap around the
eccentric B¹ and the lower end of said rod B³ is connected with a frame B mounted
to reciprocate vertically between the guides D', the said frame D being provided with
a recess or opening D2 into which one end of the shaft E projects, said shaft being
journaled in bearings in the frame of the machine, as shewn in figure 3. In the
recess D³, a ratchet wheel E' is mounted on the shaft E with which a pawl E² engages
acted upon by a spring and pivoted to the vertically reciprocating frame D. A suitable
check pawl E³ engages with the ratchet wheel and is pivoted to the frame of the
machine. In the top of the reciprocating frame D, a pawl E is pivoted which acts
on and revolves a ratchet-wheel E' united with a cog-wheel E engaged with the cog
wheel E mounted on a square shaft inserted in one end of a tubular shaft F,
figure 4. A suitable locking pawl is engaged with the ratchet wheel E³. On the
shaft E, a disc F1 is mounted which is provided on one face with a projection F2
which can act on the arm F³ on one end of a shaft F pivoted in the frame of the
machine, and provided on the opposite end with an arm F adjacent to the lower end
of the pawl E, figure 2.
As stated, one end of the shaft F is held on the square end of the shaft on which
the cog wheel E7 is mounted, and into the other or front end of the shaft, the squared
end of a shaft G¹ is passed, said shaft being journaled in a box or frame G. On the
shaft G¹, the cog-wheel G2 is mounted and is engaged with a pinion G³ mounted
rigidly on a sleeve G* in which a rod G³ is mounted to reciprocate or slide. A series
of rods G and surrounding sleeves or tubes G4 are mounted parallel and transversely
in the frame G, the pinions G³ of the several sleeves G being engaged as shewn in
figure 3.
The ends of the rods G³ projecting from the front of the casing are each
provided with a head or cap G having a recess closed by a rubber head or disc G7.
The several sleeves G also pass through a bar H resting against the inner surface of
the front of the box G and mounted at its ends on transverse rods H¹ of the box G
so as to adapt said bar H to slide transversely to the length of the box. Said bar H
also rests against cam-arms H² fixed on shafts H³ in recesses in the rear surface of the
front of the box G, said shafts H being provided with arms H₁ resting between
pins H on a bar He guided in the ends of the box G to slide in the direction of the
length of said box. The bar He also has a downwardly extending pin H' passed
through a slot in the free end of an arm I on the upper ond of a shaft i mounted to
turn on its longitudinal axis and provided on its lower end below the platform A² with
an arm 12 on which a projection 13 of a disc I' on the shaft E can act, as shewn in
figure 3.
As shewn in figure 9, the cam projections H2 rest in the recess in the rear
surface of the box G so as to permit the bar H to rest snugly against the rear side of
the front of the box G. Each sleeve G is surrounded directly behind the bar H by
a collar J through which a screw J₁ passes, said screw also passing through the
corresponding rod G' and through the longitudinal slots J of the sleeve G, which
sleeve G is surrounded by a spiral spring Ja one end of which rests against the
pinion G³ of the sleeve and the other end against the corresponding collar J. When
the bar H is moved in the direction of the arrow figure 9, the bar H is pressed
from the inner surface of the front of the box G by the cam arms H2 whereby the
collars J are moved in a like direction, as are also the shafts G* connected with the
collar J, and the springs Ja are compressed.
In front of the box G, two bars K and L are provided of which the lower bar K is
provided along the front with a rib K¹ on the top, said rib being provided with as
many segmental notches K³ as there are rods G³ in the box G, the centres of the

page_text: A
said notches being directly below the longitudinal axes of the rods G³. The upper
bar L is provided on its front at the bottom with a rib or ridge L' provided with a
longitudinal groove L², said groove L being directly above the notches K³.
U-shaped plate M is fixed at the top of a frame R, to be described later, and is
provided with two laterally projecting wings M. From the ends of the bar L,
pins L project downward and rest on the ends of the wings M³, said pins also passing
through apertures in the bar K. From the bar K the pins K³ having heads at their
upper ends, pass through apertures in the bar L springs K surrounding said pins
and pressing the bar L downward. The bar K rests on the bottom of the slots in
the supports K projecting upward from armis K held vertically adjustable on the
frame A. On one of the standards K the vertically sliding pin N is pressed
downward by the spring N' surrounding.it, said pin being provided with an arun N
which projects over a part of the top edge of the bar K. A suitable stop N³ on the
said support K prevents the spring from pressing the arm N down any further than
a short distance below the top edge of the bottom bar L. A spring N is fastened to
the frame A and one end to the bar K and draws said bar in the direction of the
arrow figure 5. An arm N having its free end notched, is fixed on the upper end
of the shaft N and one of the pins L passes through the said notch. The shaft N°
bas a curved arm N° on its lower end, one end of which arm No rests against the rim
of the dise I mounted on the shaft E. The box G is provided with downwardly
projecting pins O which pass through apertures in the U-shaped plate M, said pins Ỗ
having shoulders or offsets O' which rest on the top of said plate M.
The
In front of the bars K and L, the die-plates P and Q are provided, the upper die-
plate P being held on the reciprocating cross-piece or hammer C previously
mentioned, and the lower die Q being held on a vertically sliding frame R mounted
to slide between the guides R', said frame resting on a pin R on the front end of a
lever R2 pivoted in the frame A and provided with a balancing weight R³.
frame R has a recess in which a cam-disc S mounted on the front end of the shaft E,
is located, and on the rim of said cam-disc an arm S' rests, which projects downward
from the top piece of the frame R, as shewn in figure 1. At the off-set S on the rim
of the cam-disc S, a notch S³ is formed, the functions of which will be described
hereafter. The die-plates P and Q are provided in the edges facing each other, with
semi-circular dies which gradually decrease in diameter from the left to the right
hand ends of the die-plates, as shown in figure 1. Pins T project upward from the
ends of the box G and are surrounded by springs T which serve to press said box
downward. The die plates P and Q can easily be removed and replaced by others
having notches of different size. Suitable driving pulleys are provided on the
shaft B.
The operation is as follows;-The blanks a used for making the buttons, are shown
in figure 17, and said blanks are inserted between the die plates P and Q at the left
hand ends of the same, where the dies in the die plates are largest. The upper dies
reciprocate and acting on the blanks a draw the same inward a short distance back
from the closed end. The blank is then conducted to the next pair of dies to the
right which are slightly smaller than those in which the blank has just been located,
and the metal of the blank a is drawn in still further and so on, until the buttons
finally have been in all the dies and leave the machine in the form shewn in figure 18.
From the shaft A, the cross-piece C and the die-plate P on the same are reciprocated
and at the same time the frame D on the rear end of the machine is reciprocated and
at each up stroke of said frame D the ratchet wheel E' on the shaft E is revolved the
distance of one tooth by the pawl E on the frame D and thus the cam-wheel S on
the front end of the shaft E is revolved accordingly and as it acts on the projection S¹
of the frame R in which the bottom die Q is held, said die plate is gradually raised
and thus the die plates P and Q are gradually brought toward each other until the
completion of the revolution of the cam-disc S, when the frame R drops and the die
plates PQ are separated. Every time the wheel E' figure 2, completes a revolution,
the disc F on the same also completes a revolution and the projection F of the said
wheel F strikes the aru F3 of the shaft and turus said shaft F in such a manner

page_text: that the arm F³ shewn in the vertical position in figure 2, is brought into a horizontal
position and acting on the lower end of the pawl E', swings the upper end of said
pawl E from engagement with the ratchet wheel E³ and it is thus evident that during
the time that the arm F is in horizontal position, the pawl E' cannot act on the teeth
of said ratchet wheel E³ whereas during the greater part of the revolution of the
wheel E', the arm F³ is in vertical position thus permitting the engaging of the
pawl E with the ratchet wheel E³, so that by the vertical reciprocation of the frame D
the ratchet wheel E' is revolved. The motion of the ratchet-wheel E³ is transmitted
by the gear-wheels to the tubular shaft F and from the same to the shaft G¹ in the
box G figures 8 and 9 and from the shaft G₁ to the several cog-wheels G³ whereby
the rods G are turned on their longitudinal axis, as are also the heads G on the ends
of the same.
The flanged ends of the blanks a located between the dies P and Q rest
against the rubber discs G7 of the heads Go and by the actions of the springs J³
surrounding the sleeves G through which the rods G pass, said rubber discs G are
pressed firmly against the flanged ends of the blanks a. The rods G³ are thus
revolved and rotate by frictional contact, the blanks resting against the rubber
discs G' and thus it is evident that the blanks are rotated during the greater part of
the revolution of the wheel E' that is, they are revolved as long as the arm is in
vertical position and the pawl E is engaged with the ratchet wheel E³. As soon as
the projection F of the wheel Facts on the arm F3 of the shaft and the arm F³ of
the shaft F is brought into horizontal position the pawl E is disengaged from the
ratchet wheel E* and consequently the rods G come to a standstill and do not rotate
the blanks a.
This rotation of the blanks is necessary, so that they receive each stroke of the dies
in a different position, as otherwise the metal of the blanks would not be drawn
inward but would be compressed or flattened. The blanks remain in one pair of dies
during one entire revolution of the shaft E which corresponds to as many blows from
the die plate as there are teeth in the wheel E. Every time the wheel E' has made
a revolution, the blanks must be conveyed to the next pair of dies. This is accom-
plished in the following manner;-As previously stated, the bar K is supported by
the standards K. The bar L is supported by means of the pins L³ from the plate M
resting on the frame R, and is pressed downward by the springs K. When the cam
disc S is in the position shewn in figure 1, the frame R is not raised during the first
part of the revolution of the said cain disc, as the part of the cam between the off-
set S and the shoulder S³ is concentric to the centre of the disc. As soon as the arni S¹
has passed the shoulder S³, the frame R is moved upward and thus the upper bar L
which is supported from the plate M on the frame R, is also moved upward and so on
until the disc S has completed its revolution when the frame R suddenly drops, the
bar L drops with the frame R and is pressed upon the flanges of the blanks whereby
said blanks are securely held between the bars L and K. If said bars L and K are
now moved to the right the distance from one pair of dies to the next pair, the blanks
will be conveyed with said bars and will be shifted from one pair of dies to the next
pair.
At the same time that the bar L is moved downward to grasp the block in the
manner described, the end of the curved arm N° snaps off the projection or shoulder I'
of the cam disc 1 on the shaft E and the spring N³ draws the bars K and L in the
direction of the arrow a' figure 5 whereby the arm N' on the shaft N is moved in
the direction of the arrow a figure 4. The die-plates P and Q are separated as the
arm S¹ of the frame I which holds the lower die plates Q, has dropped off the offset S
of the cam disc S the moment before the end of the curved arm No slips off the highest
point or offset I' of the can disc I¹. After dropping off the offset I'
of the cam disc I', the end of the arm No runs on the part 1 of the rin
of the disc I and as that part I is concentric, the arms N° and N' on the shaft NB
are not shifted. During the time that the end of the arm Ne travels on the con-
contric part 1 of the rim of the disc I, the frame R is gradually raised and thereby
the bar L is raised and the blanks released, said blanks being now held between the

page_text: two dies; then the concentric part of the rim of the disc I begins to act on the end of
the arm N of the shaft N8, whereby said arm N and the arm N' are moved in the
inverse direction of the arrow a figure 5 ready to shift the blanks again for the next
rotation of the shaft E. The blanks are thus held loosely between the dies during
the operation of drawing inward the metal, but at the end of each revolution of the
shaft E, the bar L descends upon the rims of the buttons in consequence of the
lowering of the frame R, then the bars K L are shifted in the manner set forth, and
so on. During the time that the blanks or buttons are being shifted in the manner
set forth, it is necessary that the rubber discs G7 on the heads G should be withdrawn.
At the same time that the blanks are grasped or held by the bar L, the projection [*
on the rim of the disc I' acts on the arm I of the shaft i whereby the arm I of the
shaft is swung in the direction of the arrow figure 4 and acting on the pin H'
projecting downward from the rod H. moves said rod H in the direction of the
arrow a figure 9, whereby the arms H are swung in the direction of the arrows
figure 9, and the cam arms H2 swung inward and acting on the bar H press the same
toward the rear of the box whereby the collars are also pressed to the rear and as
said collars are connected with the sliding rods Go said rods and their heads Go are
withdrawn from the ends of the blanks. After a short time, the arm I is disengaged
from the projection 13 of the dise I and the springs J³ expand and press the rubber
dises G against the blanks, and thus the blanks are revolved, as before described.
It is evident that the rods Go for turning the blanks, must ascend and descend with
the lower die holder and for this reason the box G is supported on the plate M secured
on the frame R. From the above, it is apparent that for each stroke of the machine,
a finished button is thrown from between the die-plate at the right hand end of the
machine, and a fresh button must be introduced at the left hand edge. The edge of
the blank is placed in a recess in the bottom bar K, and the upper part of the blank is
pressed down by the arm N2 figure 5. Said blank is then moved in between the die-
plate in the manner previously described, and gradually conveyed to the right hand
ends of the die-plates.
