The working parts of the machine are, for the most part, enclosed in a case con-
sisting of two portions, A and A', secured together in any desired manner, as by
screw bolts, JJJ fitting into the holes J J J
A reciprocating up and down motion is given to the rack N from which motion is
transmitted to all parts of the machine. To this end the case A A¹ may be screwed,
or otherwise attached to an ordinary treadle base, the rack N being secured to the top
of the upright rod connecting with the treadle; but reciprocating motion may be
given the said rack in any other desired manner.
The rack N is provided near its upper end with a pin 2, Fig. 3, which engages in
a slot v in one end of a lever V, pivoted at C. VI is a connecting bar pivoted at
one end to the lever V and at the other end to the friction clutch I by means of which
an intermittent rotary motion is given to the spindle C on which the drums B B¹
are fixed.
This clutch shown in detail in Fig. 12 consists principally of a wire I² bent into
a coil of sufficient size to enclose the spindle C, and secured at one end around
a post 3, the wire being enclosed in a case having a cover 1¹ secured thereto.
During the motion of the clutch in one direction the coil 1 tightly closes around
the spindle C which it turns through the same arc as the clutch itself. During
the motion of the clutch in the opposite direction the coil 12 slips over the spindle C
which is prevented from turning, except in the direction indicated by the arrows,
by means hereinafter described. The clutch thus acts as a pawl and ratchet in
giving intermittent motion to the shaft. The position of the slot 2 is such that
the motion transmitted from the rack N through the lever V and the connecting
bar V¹ to the clutch I is considerably reduced.
All the working parts enclosed in the case A A¹ derive their various motions
from the three cams F F F mounted on the spindle and made preferably in
one piece, as shown in Fig. 5. From the pinion N¹ which turns loosely on the
spindle and engages with the rack N, an intermittent rotary motion is imparted
o the said cams as follows:-
At each down stroke of the rack N the pinion turns one revolution, in one
direction, turning back again during the up stroke. At the beginning of the
down stroke of the rack, the pin or tooth.n (Fig. 5) on the face of the pinion Ni
nearest the cam F engages with the slot on the face of said
the
cam,
shape of which slot, as best shown in Fig. 15, is such that when the pinion is
turned in the direction of the arrow during the down stroke, the cams FF and F
are turned with the pinion one revolution, the spring S bearing against the opposite
face of the pinion N from the pin n serving to press the pinion against the cam and
keep the pin in the slot. During the up stroke of the rack N, the pinion being
turned in the opposite direction, the pin slips backward out of the slot n' against
the pressure of the spring S12, and moves with the pinion around the face of the
cam F which remains stationary until at the end of the up stroke of the rack the
pin has again engaged with the slot to move the cams, as before, on the next down
stroke, and so on.

attachments perform the various functions of presenting a fastener at the proper
moment under the die P, passing it up through the leather or fabric and clinching
the same through the button eye under the die, as will be fully described hereinafter.

page_text: The buttons are introduced in quantity through the funnel shaped attachment B³
into the drum B, and the fasteners through B3 into the dram B1, communication with
the interior of the drums being opened or closed by means of the plates Z Z
swinging on the hubs B+ B and operated by the handles ii, respectively, in a
manner easily understood by reference to Fig. 4. The drums B and B contain
the buckets and respectively, by means of which the buttons and fasteners
are raised to be dropped, the buttons upon the trough D and the fasteners upon
the fastener trough E.
The shape of the inclined trough D is such, that while broad and somewhat flattened
at its outer end to form a suitable receptacle for the buttons as they fall onto it, it
soon narrows down into the channelled portion which is of sufficient width to
allow a
single row of buttons to slide therein with their eyes down, as shown in
Fig. 2. The trough is supported near its inner end by the part D3 which is soldered,
or otherwise secured directly or indirectly to the body of the machine. K and K¹
are a pair of guide rollers provided at equal intervals along their circumferences with
the grooves parallel to the axes of the rollers. They are each provided also with a
circumferential groove ³ (see Fig. 13) near the outer edge of the rollers in which
lies the button feed wire D². This bent wire D starting from the end of trough D
passes partially around the peripheries of the two guide-rollers K and K¹, as shown
in Figs. 2 and 7, in such a manner as to be held perfectly stationary as the said
rollers revolve, thence it passes along the raceway D' through the channelled
portion D in the forwardly projecting part of the frame and terminates at the
die P under which the clinching of the fastener around the button eye is accom-
plished. The trough D is provided near its outer end with the spring wire d bent at
right angles at its top and bearing against the internal ratchet teeth 32 with which
the drum B is provided. As this drum revolves in the direction of the arrow shown
thereon, the wire imparts a jarring motion to the trough D causing the buttons,
with the aid of gravity, to travel in a stream along the channelled portion d³ to
the end of the trough from which they then drop off. Many of them are in suitable
position to be caught by their eyes on the upper protruding end of the wire D2.
Those that do not catch in this way fall back along the bevelled portion A³. to the
bottom of the drum B. The buttons are taken one at a time, from the upper vertical
portion of the wire D³ by the grooves in the roller K¹, as they come around, and
are carried along on the said wire, which passes under the roller K' and over K, by
the bearing of the grooves as the rollers revolve against the eyes of the buttons
resting therein, as is clearly shown in Fig. 2, the buttons being pressed from one
roller to the other in a manner easily understood by reference to that figure in
which the eye of a button (the head being removed) is shown in the act of being
thus iransferred from one to the other. The button heads are kept
proper position
by the guides D³ and D. From the guide roller K the buttons are crowded upon
the wire D2 along the raceway D' as far down as the notched separator T, by which one
button at a time is taken and allowed to drop down to the end of the wire 1)² at: the
proper time to be seized and carried through the required operation of fastening, as
hereinafter described. The guide rollers K and K¹ are operated as follows:-The
roller K, having the hollow spindle is secured to the gear wheel K³ to turn with it.
On the same hollow spindle run loosely the gear wheel K and the circular
plate, provided with a notch in its periphery. k³ is a spiral spring the outer
end of which being circular is sprung into a circular groove made near the outer
end of the hollow spindle. This spring pressing against the plate 7 tends to
make the wheel K, while loosely turning on the spindle ko, bear with considerable
friction against the gear K. The hollow spindle with its attachments, as shown in
Fig. 13, turns on the spindle C3 fixed in the casing K secured to the frame of the
machine (see Fig. 4). On the spindle C similarly fixed in the casing K² turns the
third gear wheel K and the guide roller K¹ secured thereto, K and K³ meshing
together. The drum B is provided with an internal annular gear 6 which works with
the loosely running gear K. As long as that portion of the wire D² lying between

page_text: the notched separator T and the guide roller K is crowded with buttons, the resistance
causes the
gear K to turn on the hollow spindle while the gear K³, and hence the
guide rollers K K², remain stationary. As soon as one or more buttons have been
removed from below by the separator T the resistance is removed and the friction of
the gear K against the gear K³ causes the guide rollers to move until the feed wire
is again crowded. In this manner there is always a store of buttons on the inclined
portion of the wire D³.
F3 is a plate pivoted at f to the case A and having an internal cam shaped opening.
This plate F³ derives an intermittent rocking motion up and down from the cradle L,
as seen in Figs. 2 and 7. The upwardly projecting part L³ of the cradle is provided
with a shoulder which, during the upward motion of the cradle, bears against the
pin on the plate F³ near its pivot thus moving the said plate F³ upward. The
downward motion of the plate is effected by the pin I which, when the cradle descends,
bears against the inner cam shaped opening of the plate, thus bringing it down against
the stop fixed in the frame.
The separator T is a notched disk pivoted at 2 on the forward inclined portion of
the frame near the channel D' in which lies the feed wire D. A wire t, see Figs. 2
and 7, bent at one end through a hole near the outer edge of the disk T and at the
other around the pin f3 in the plate F³ serves as a connecting bar whereby, as the said
plate F³ moves up and down, an oscillating motion is given to the disk T between the
positions shown in Figs. 1 and 14 corresponding to the extreme up and down positions
of the cradle L respectively, The upper curved edge of the disk T is preferably the
are of a circle struck from the pivot t, and against this curved edge rests the lowest
of the row of buttons strung on the wire between the guide roller K and said
disk T, when the latter is in the position shown in Figs. 1 and 6. When the disk T
is in the position shown in Fig. 14 the said lowest button of the row drops into
the slot, and, the disk quickly moving into the position shown in Fig. 1, the
button is moved along the wire D2 and drops down by gravity on the vertical part
of said wire.
It will be observed that the duty of the guide rollers K K is two-fold, being first
to properly feed the buttons along the wire, and secondly to hold said wire positively
in place. I may use, if desirable, more than two such rollers, but whatever the
number of rollers employed, it is intended that the feed wire will be bent for sufficient
distance around their peripheries as to be held stationary as the rollers revolvo
without being confined elsewhere, thus providing an unobstructed pathway for the
button eye from one end of the said feed wire to the other. The wire D² is so
bent around the two said rollers that its absolute position is determined without its
being held at any other point.
M M are two gripper jaws which seize the button, as shown in Fig. 1, by the eye,
remove it from the feed wire D' and carry it under the die P. The jaws M are swung
loosely on the pin f fixed in the plate F³, one jaw on each side of the U-shaped
frane M also supported on the pin 5. The spring S presses the jaws M against the
sides of the frame M', but they are so loosely hung on the pin as to admit of being
separated laterally at their lower end against the pressure of the spring, which,
however, tends to keep them normally pressed together at the said lower end. The
frame M and jaws M are pivoted on the pin to swing outwardly, but the coiled
spring S pressing between the frame M and the pin 7, serves to keep the lower end
of the frame and jaws pressed inward toward the machine. On the back of each leg
of the U-shaped frame M' is a cam shaped projection m² which is pressed against
stop m fixed to the frame. m m are two pins fixed in the frame M' fitting loosely in
holes in the jaws M M to serve as guides for the latter as they separate laterally.
00 are two cheeks passing one on each side of the die P and terminating behind it
in the bar O¹. The bar, and with it the cheeks O, derive a reciprocating back and
forth motion from the lever G pivoted at C. The cam F¹ on the spindle (³ bears
against the roller G' and in connection with the spring So, which indirectly acts, as
will be presently more fully explained, to keep, the roller G in contact with the cam
a

page_text: gives the said lever G an intermittent oscillating movement back and forth. By
means of the roller G on the back of the lever bearing against the cam shaped under
side of the bar O¹ acting in connection with the pin O working in the slot O' and the
spring S, an irregular reciprocating motion of the lever G is imparted to the bar O'
and thence to the cheeks O, which have also a slight upward movement as they
are drawn back into the machine, as will be seen by reference to Figs. 2 and 7
especially.
To understand the operation of the gripper jaws MI, let us start with the machine in
the position shown in Fig. 7 with the craille L, and hence the plate F³, and the gripper
jaws M, at their lowest position. The checks O are at their forward position being
preferably flush with the front face of the die, while the jaws have just conveyed a
button under the said die.
A fastener rests on the forward end of the clinching bar . The leather or cloth
being introduced between the fastener and the dic, the rack N is moved downward,
which causes the cradle to rise, the point of the fastener being driven through the
leather which is thus pressed upward against the bottom of the jaws. This pressure
is resisted by the bearing of the jaws against the bevelled under side of of of the
cheeks O, the pressure upward tending, as will be seen in Fig. 14, to lock the two
jaws together and strip the leather down upon the fastener. The fastener having
penetrated the leather passes through an opening between the two jaws on the under
side thereof and enters the button eye still held by the jaws under the die. The
fastener is then released from the clinching bar and the checks 0 0 are next with-
drawn back of the die. At this point the shoulder coming in contact with the
pin causes the plate F³ to begin its upward movement, carrying with it the jaws M
which are separated as they move upward by the rounded sides of the die P over
which they pass thus releasing the button which now hangs on the fastener with its
eye under the die. When the jaws M snap together again above the die under the
influence of the spring S, they tightly close around the eye of the button resting
just on top of the die, as shown in Fig 2. At the same time that the jaws rise, the cam-
shaped projection m² passes above the stop m³ allowing the lower end of the jaws to
be pressed back slightly under the influence of the spring S. By this means the jaws
close together over the eye of the button above the die, instead of pressing against
the button head. Meanwhile the cradle has completed its upward motion and
clinched the fastener around the eye of the button. The action of the slotted
disk T, previously explained, in separating the button from the row above, and
allowing it to drop along the vertical portion of the feed wire, takes place
simultaneously with the closing of the jaws M on the button above the die, as in
Figs. 1 and 2.
Before the rack N has reached its lowest point, the checks O are pressed forward,
pushing the lower end of the jaws M outwardly before them. The jaws grasping the
button by the eye cause the feel wire D' to spring out of the notch in the front of the
lie, so that when the cradle descends rapidly, as it now does at the end of
the downward motion of the rack N, the jaws M, descending also, carry the button
off the feed wire, which springs back into the notch in the die, and convey it
under the said die in the position shown in Fig. 7, the jaws spring back flush
with the front of the die under the action of the spring S8 after having passed
beneath the cheeks O.
The fasteners being dropped from, the buckets of the drum B¹ upon the outer
flaring portion E of the inclined fastener trough, travel along down the same, as
shown in Fig. 10, by the jarring action of the wire e which works with the
internal ratchet teeth in a similar manner to the wire d on the button trough.
The peculiar shape and tilted position of the fastener trough (clearly shown by the
section in Fig. 5) causes most of the fasteners falling on the upper portion of the
part E in an upright position, to travel regularly down the same into the raceway e e'.
Fig. 11 shows a cross section of the raceway on a larger scale, and also shows clearly
the peculiar shape of the metallic fastener E used in this machine. The curved

page_text: fastener raceway is made up of the strip e3 which is attached to or cast with the
part A³ of the frame of the machine. On this are screwed the curved strips e e¹,
separated by pieces e²e, allowing a suitably shaped channel for the fastener which is
confined therein by its head. The strip e passing through the aperture of the part A³
of the frame terminates in the point which is so situated as to canse those fasteners
which are not in proper position for passing into the race way e e¹, to drop back
into the drum.
U is an oscillating arm pivoted at C7 to the case A¹, and which rocks back and forth
under the fastener raceway, as shown in Fig. 3. The rocking motion of the arm U
is brought about by the part a of the cam acting alternately upon the projecting
portion and upon the bent lever W2 pivoted at w to the casing A¹. is a pin
fixed in the back of the arm U so as to engage in a notch in the upper end of the
lever W. The part a of the cam F first strikes the projecting end of the rocking
arm causing the upper end of said arm to move forward to the position indicated by.
the dotted lines in Fig. 3. Then a passes by and strikes against the rear end of
the lever W thereby rocking the arin U back to the original position. The motion of
the arm back and forth is limited by the slot working over the pin wl. The upper
end of the arm U is bifurcated, as shown in Figs. 16 and 17, and contains the strip u,
the shape of which is best shown in Fig. 3, pivoted to the arm at . The rear lower
portion of the strip projecting beyond the arm, is pressed against the same by the
spring Into the bifurcated portion of the arm U projects the lower end of the
curved plate e of the fastener raceway, and bears against the curved upper edge of
the strip u. The forward upper edge of the arm U is cut away to form a shoulder u³,
and the forward end of the strip u terminates in the tongue u, which, when the arm
is in the backward position, is pressed up on a level with the top of the shoulder u
by the action of the spring . In this position the space between the shoulder and
the tongue is immediately under the row of fasteners in the raceway e e¹, which is
constantly full of fasteners. The upper curve of the strip is such that when the
arm is moved to its forward position, the said strip is pressed downward by the bearing
of the under edge of the plate e against the said curved upper edge and the tongue u
is depressed against the action of the spring u³, as shown in dotted lines representing
the forward position of the arm in Fig. 3. Each time the rocking arm U moves
forward, it conveys a fastener from the raceway to the hinged fastener carrier (see
especially Figs. 2, 7, 16 and 17) by which it is transferred to the top of the clinching
bar I.
The hinged fastener carrier, pivoted at 74 to the rod H2 which is rigidly secured to
the case A, consists of the side piece h, the semi-cylindrical part H, the portion ¹ on
which rest the head of the fastener, and the grooved block secured to the plate
and hinged at ³ to the side h. A spring S bearing between the semi-cylindrical
part H and the plate 16, tends to keep the block 2 pressed lightly downward against
à suitable stop. The cradle L is provided with the upwardly projecting portion L,
Fig. 8, which has a shoulder 1. The front surface of Labove the shoulder bears
against the flat face of the semi-cylindrical portion H of the fastener carrier when
the cradle is down. The light spiral spring is secured at one end to the
casing A, and passing partly around the cylindrical portion from behind and
below, is attached at the other end to the part H. When the cradle is up, as in
Figs. 2 and 17, the hinged carrier is down, for then the shoulder on the
upwardly projecting part of the cradle having passed above the semi-cylindrical
position H, the tension of the spiral spring turns the carrier down at right
angles to its former position, with the flat face of H horizontal beneath the
shoulder 2. When, on the other hand, the cradle moves down to the position
shown in Figs. 7 and 16, the shoulder bearing against the edge of the flat face
of H acts as a tooth and turns the carrier up with the said fat face vertical
against the face of L'. To avoid unnecessary complication, both in Figs. 16
and 17 several parts of the mechanism have not been drawn in that would really
appear, all parts, with the exception of those necessary to show the action between

page_text: the rocking arm, hinged carrier and clinching bar being broken away or left out
altogether. The fastener being held in the space between the shoulder and the
tongue on the rocker arm U the arm moves forward, the tongue ³ is
pressed down, as previously explained, and, the hinged carrier being up, the
fastener is pressed into it, as shown in Fig. 16, the head of the fastener bearing
against the part ', while the point is pushed into the groove in ², the fastener
being held by the spring pressure of h². The rocker arm then quickly moves
back. This takes place at the beginning of the downward stroke of the rack N,
the cradle being down. The cradle then moves up and, the hinged carrier moving
down, the part meets the upper surface of the clinching bar I just back of the
shoulder, the upper surface of containing the fastener head, being on a level
with the top of the clinching bar I in front of the shoulder and the fastener
being, of course, in an upright position, as best shown in Fig. 2.
The removing of the fastener from the hinged carrier and its final conveyanco
to the front of the clinching bar .L', is effected by the sliding carrier R R¹, shown
in place on the clinching bar in Fig. 8, and by itself in Fig. 9. This carrier is
made preferably from strips of thin metal bent to form the two guides R R¹,
which are fixed one on each side of the block R². The horizontal portions of
these pieces are adapted to fit easily the grooves on each side of the clinching
bar L, in which the carrier slides back and forth.
Near the upper end of the oscillating lever G is the pin G³ which works in the
slot R in the block R². As the lever oscillates back and forth by the action of
the cam F, as previously explained, it causes the sliding carrier R R¹ to move
back and forth along the clinching bar. R³ is a bar projecting forward from the
block and forked at its forward end 3. The two strips R R are bent at their
forward end to form spring jaws R R over the top of the clinching bar.
When the hinged carrier has brought the fastener down into the position shown
in Figs. 2 and 17 the sliding carrier R R is at the back of its stroke. It imme-
diately begins to move forward, however, and the fork of the bar R³ seizing
the fastener removes it from the hinged carrier, sliding it along under the spring
block L. The object of this latter device is to turn the fastener in the proper
position for clinching. The fastener being of irregular shape, it is necessary that it
be presented under the die in one position, viz., with its upwardly curved neck
pointed toward the rear. It is more than likely that most of tlie fasteners will have
been turned in that position by the action of the rocker arm in depositing them on
the hinged carrier, but to turn those that are not in the right position, the block L
is used. In Fig. 2 a portion of the casting is broken away to show the action of
the block which is pressed down upon the stops 13 13 by the springs. The
pressure of the block against the top of the fastener while the latter is being pushed
along under it by the forked bar R³, causes the fastener to be turned in the proper
position, if it has not previously been so turned, and the fastener is left by the
forked bar with its point in the retaining groove near the forward end of the block L.
To aid in the turning process the under side of the spring block is preferably bevelled
out slightly as at .
Just after the fastener has been removed from the hinged carrier the cradle begins
its swift descent near the end of the down stroke of the rack N, and at the same time
the hinged carrier quickly springs up to receive another fastener at the beginning of
the next down stroke.
The sliding carrier R R¹ having left the fastener under the spring block L moves
backward, and the jaws R R at the forward end of the carrier, coming in contact
with the fastener, spring apart allowing the fastener to enter and be held in the
notch, the fastener being prevented from moving backward by reason of the shoulder
in the retaining groove. While the cradle is dropping down the sliding
carrier R R again moves forward carrying the fastener held between the jaws R³ R
to the front of the bar L' and under the die P, and at the same time the forke:
bar R³ moves forward another fastener from the hinged carrier to the forward end
of the spring block L. The sliding carrier R R remains at its extreme forward

page_text: position until the cradle L has risen sufficiently to push the point of the fastener
through the leather and into the eye of the button held in the jaws M, when it quickly
moves backward, the jaws R R springing apart and leaving the fastener. The
clinching of the fastener is then completed, as was previously explained.
It will be observed that the leather does not press directly against the die during
the operation of clinching but is separated therefrom by the spring jaws M, against
the smooth under surface of which the leather is pressed while being stripped down
onto the fastener as it rises.
All the operations are performed during the down stroke of the rack N. The
motions of the cradle Land of the sliding fastener carrier R R are variable, as will
be seen by the irregularity of the cams F and F¹.
When the machine at rest, the cradle and jaws are down and the hinged
carrier up.
To trace the operations in their order, the very first operation at the beginning of
the down stroke of the rack N is the quick motion of the rocking arm U back and
forth to place the fastener in the hinged carrier. The hinged carrier then moves
down as the cradle quickly rises until the point of the fastener penetrates the leather
and the button eye, when the cradle stops for a moment, and at this point the sliding
carrier R R is drawn back. Then the cradle slowly rises with gradually retarded
speed through the small distance necessary to clinch the fastener, and simultaneously
therewith the jaws M release the button under the die and separate as they quickly
rise over the die closing together over the eye of the button above it. At the same
time that this motion takes place, the slotted disk T turns on its pivot separating a
button from the row above it on the feed wire and allowing it to drop down the
vertical portion of the wire. Finally, just before the end of the down stroke of the
rack the cradle drops down to its lowest position and at the same time the sliding
carrier moves forward bringing a new fastener to the front, the hinged carrier
springs up, the cheeks OO move forward, the jaws M strip the button off the feed
wire and carry it under the die, and the separating disk returns to its former position.
with its slot inclined upwards. All operations.then; cease during the up stroke of the
rack to be repeated as before on the next down stroke.
The clinching bar L' is not rigidly attached to the cradle, but is cushioned therein,
as represented in Fig. 2, the cradle being there shown partly in section so as to make
clear its interior construction. The pivot C on which the cradle rocks passes tightly
through the same to turn with it, but allows the bar L' to turn loosely thereon,
while the pivot itself turns easily in its seat on either side of the machine.
Near the rear of the bar L' are the stiff springs S* S* S* between it and a second
bar L which bears at its upper forward end against the bar and rests on the
pin fixed in the cradle. The bar I has a short slot which works on the pin 1° also
fixed to the cradle, thereby enabling the bar L to play up and down to a slight extent
independently of the cradle. The downward pressure on the outer end of the clinching
bar due to the clinching of the fastener is thus transmitted through the cushioned com-
pound levers L' L² the result being that the machine is thereby adapted to secure
buttons to leather of varying thickness, and at the same time the cushioning
compensates for the wear of the working parts.
'
It has been found best in practise to bevel the extreme forward end of the clinching
bar L forming thus an inclined seat 1 for the fastener. This bevelled seat causes the
fastener to incline forward slightly to the line of motion, and thereby aids effectually
in the clinching of the fastener around the button eye.
The particular form of machine herein described and illustrated is intended, as was
said before, to be secured to the top of an ordinary pedestal in which an upriglít rod is
given a reciprocating up and down motion by means of a treadle working against a
spring, the said rack being secured to the upright rod. It will be seen, moreover,
that during the earlier part of the stroke the least practical work is being done by the
machine, while near the end of the stroke, when the foot has nearly reached the
bottom, the clinching of the fastener takes place.
Furthermore, if the spring S were to act directly upon the lever G to keep the

page_text: roller G' against the cam F¹ the force required in pressing down the treadle near
the end of the stroke would be enormously increased by reason of the fact that in
addition to the hard work of clinching the fastener, much force would have to be
expended on the treadle in moving it against the resistance of the spring S°, which is
then pulling its hardest in the opposite direction. To equalize to some extent the
work done, by increasing it at the early part of the stroke and diminishing it at the
end, and hence insuring a more uniform motion of the rack N, I have introduced
the triangular plate F, Figs. 2 and 7, which is pivoted at g₁ to the case A. The
connecting bar G is pivoted at one end to the lever G and at the other to the face of
the plate F. On the back of the said plate F* a bar is pivoted at one end g² to
the plate and at the other end g³ is attached to the spring So, the pivotal points being
in such relation to each other that when in the earlier part of the stroke the cam F
begins to move the lever G to the right, the resistance of the spring S which would,
if directly connected to the said lever, be comparatively light at first, gradually
increasing as the spring became more deflected, in this case acts in just the reverse
manner, being greatest at first, and gradually diminishing. The reason of this is that
when the said lever G begins its motion to the right, as in Fig. 7, a little movement
on the part of the lever causes the end of the spring to move through many times the
same distance, whereas near the end of the movement of the lever, as in Fig. 2, though
the spring is then in reality pulling its hardest yet the lever must move through con-
siderable distance to deflect the spring even a little. Hence the actual work done is
more evenly distributed throughout the stroke.
The spindle C is prevented from turning, except in the direction of the arrow, by
means of the detents d and e, which serve also, as has been said, to give the jarring
motion to the button and fastener troughs.
The form of fastener shown in Fig. 11 is best adapted for use in this machine. It
consists of the shank e¹0 set eccentrically on the head e, the upper end of the shank
being curved slightly at the point as shown, the fastener being of such a shape that
when pressed upward against the die it will be suitably bent around and firmly hold
the button to the leather or other material.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me by my
foreign correspondent I declare that what I claim is :-
