page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, 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:-
My invention relates to improvements in machines chiefly designed to attach
buttons to garments, and especially sectional buttons wherein one section provided
with a post or stud is attached to one fly of a garment opening, and the other
section provided with a hollow rivet or tube adapted to receive said post, is attached
to the other fly of the garment.
In the accompanying drawing
Figure 1 is a side elevation of one side of my improved machine with the jaws
closed.
Figure 2 is a side elevation showing the side opposite to that shown in Figure 1,
with the jaws open.
Figure 3 is a plan or top view of the face of the anvil,
Figure 4 is a central vertical section of the same.
Figure 5 is a central vertical section drawn to an enlarged scale, of the anvil,
with a button section, the fabric, and a washer resting thereon, in position to
be set.
Figure 6 is a front elevation of the machine.
Figure 7 is a vertical section of the upper jaw and the perforated swage and
plunger.
Figure 8 is a side elevation of the post section of a button.
Figure 9 is a plan view of a washer.
Figure 10 is a vertical central section of the post section of a button attached to
the fabric.
Figure 11 is a view in elevation of the slotted tube.
Like letters of reference indicate corresponding parts in all the figures.
A is the bed plate or frame of the machine which supports the anvil C.
The upper member B' is fulcrummed upon the frame by the pivot A' and provided
with the lever B.
.

page_text: The end of the lever B and the frame A are connected by a toggle joint formed
of links I and J. The knee of this joint is connected with lever B by another
toggle joint made up of the links H and F. The link F is provided with a
swinging lever G integral therewith or securely fixed thereto.
The lever G is provided with a convenient foot-rest G¹ at its lower end for
operating the same, and, through the compound toggle-joint thus formed, the
lever B and fulcrummed member B¹.
By swinging the lever G backwards and forwards the connecting parts are
changed from the position shown in Figure 1 to that shown in Figure 2 and back
again, from which it will readily appear that great power is obtained without a
very extended sweep of lever G, and that gravity, acting through lever G and the
connecting parts secured to lever B at two separate joints will restore the parts
to the position shown in Figure 2 after they are released from constraint in position
shown in Figure 1.
K is an upright, supporting the stop K¹ which may be made of india-rubber or
other elastic material to receive the projecting end L of lever B.
The member B¹ is provided with the swage D having an opening D¹ therein
adapted to receive the rounded end of post m of a button section such as shown in
Figure 8.
The post is provided with a projecting step t extending up a short distance from
the upper side of the base c and adapted to be swaged down upon a thin washer r
placed thereon after the post has been inserted through the fabric to which the
same is to be attached, which is the object to be accomplished by the perforated
swage D. After the post has been inserted in the fabric and the washer adjusted
thereon the head of the post is inserted in the perforation D1 and the swage forced
down towards the anvil C, by means of the lever G, until the base of the button
section striking the anvil forces the projecting step against the swage, which
upsets the edges upon the washer and secures the section upon the fabric as
shown in Figure 10.
The opening D¹ is provided with slight enlargement around its mouth as
shown in Figure 7 which serves to control the movement of the edges of the step
while being upset by the swage and give them a uniform and smooth appearance;
it also serves to present a ring projecting down below the working edge of the
swage to push the washer down below the upset edges of the step while they are
being upset.
As the post m is forced with great pressure into the opening D¹ it frequently
adheres very firmly to the swage, I.have therefore provided the plunger a, adapted
to slide vertically within the opening in the swage and strike at its upper end the
stop E on the upright E when the member B₁ recedes from the anvil, thereby
forcing the plunger into the swage and driving the post therefrom and releasing it.
I do not regard the stop E¹ as a necessary element, because the plunger a may
be operated by a hammer in the hands of the operator.
To set the other section of the button I provide another fulcrummed lever
consisting of the member P fulcrummed at i, and provided with the operating
lever P, which connects with lever B as shown in Figure 6, and with the setting
punch or hammer d, operating in conjunction with the anvil g which rests upon the
bed plate or frame of the machine.
The section of the button set by this part of the machine is the button head
and is shown in vertical section in Figure 5. It is composed of a chambered spring
enclosing a shell provided with a centrally projecting post-receiving tube u.
The tube is slotted transversely at one side, as shown in Figure 11, to receive
the spring locking catch v, shown in Figure 5. This catch serves to engage with
the groove o in the post shown in Figure 8 to hold the two button sections together
when in use.
The slot in the tube lessens its power of resisting "the force of compression
necessarily applied at the ends of the tube in setting the button head upon the
fabric. I therefore provide the support n projecting centrally from the anvil g

page_text: as shown, the utility of which will be readily seen upon examination of the method
of attaching the head to the fabric. The head is placed upon the anvil g bottom
side up, and the fabric upon the head, so that the tube u projects up through the
same as shown in Figure 5.
The washer with a central aperture just fitting the tube is then laid upon the
fabric, so that the tube projects up through the washer also, as shown in Figure 5.
The lever G is then put in motion, causing the member P of lever P¹ to descend
toward the interposed button head and carry before it the plate e pivotted upon i
and actuated and controlled by the spring S (shown in dotted lines in Figure 2)
coiled around the setting punch d, until the plate strikes the washer and forces it
down firmly against the fabric arresting the movement of the plate.

The member P continues to advance against the yielding spring, thus forcing
the punch & through an aperture in the plate to make contact with the projecting
end of the tube which it upsets and bends over upon the surface of the washer, as
shown by dotted lines in Figure 5, thereby firmly securing the head to the fabric.
Meanwhile the catch v, resting in the slot of the tube and upon the support n
has held up that side of the tube and enabled it to withstand the force of com-
pression employed in upsetting the tube upon the washer. The plate e also served
to hold the washer tightly upon the fabric until the tube was upset thereon and
then rose again to the position shown in Figure 2.
The spring S need not necessarily surround punch d, but may occupy any
convenient position between the plate and member P, and may be wholly a
controlling spring, the plate being held down by the hand of the operator through
the handle shown by dotted lines in Figure 2.
My invention is equally applicable to any device in which the swage and punch
or anvils receive a reciprocating motion whether they travel in fulcrummed levers
or sliding plungers.
Having now particularly described and ascertained the nature of my said
invention 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 :-
First. In a button setting machine, the combination with the frame A and lever B,
of the links H, I, J, F, and the lever G carrying the foot rest G³, as, and for the
purpose, described.
Second. The combination with the anvil C, of a swage D provided with an
opening or perforation D¹ slightly enlarged at the mouth thereof, whereby a step t
on a post m may be swaged, as described.
Third. The combination with the perforated swage D, of the spring plunger a
and the stop E¹ on an upright E of frame A, as, and for the purpose, specified.
Fourth. The combination with the lever B and anvil g, of the lever P, P¹
carrying the punch d, as shown and described.
Fifth. In a button setting machine, the combination with the anvil g having
a concave top, a central projection n and a punch d, of the spring S and hinged
plate e, the latter having a hole to receive the punch, as shown and described.
