Improvements in Apparatus Employed in the Manufacture
of Buttons.
I EMIL BRILL of the firm of Gebrüder Brill of Barmen, Rhenish Prussia in the
Empire of Germany Manufacturers, do hereby declare the nature of this invention to
be as follows:-
My said Invention relates to apparatus for use in the manufacture of buttons
composed of a metal backing faced with cloth or other material such buttons for
example as are referred to in a provisional application for Letters Patent No. 3509 made
by me on the 8th day of March 1887. Speaking generally such buttons consist of a
metal foundation over which the cloth covering is placed and a cupped metallic backing
which is rivetted or united by pressure to the said metal foundation, the cloth facing
being by the same operation drawn tightly over the front of the button. The cupped
backing is or may be formed with teeth at its periphery, which teeth enter perforations
or are forced into a recess in the foundation, clenching the parts of the button
together and securing the cloth covering at the same time. The periphery of the
backing may however be formed without teeth. The apparatus which I use for
securing the component parts of such buttons together and which forms the subject
matter of the present application consists of a small press composed of two parts
capable of being screwed together. One part consists of a hollow sleeve bored to fit a
sliding mandril which is provided at its outer end with a capstan head or handles by
which force can be applied to the mandril. The mandril has also a pin which works
in a slot of a form, the traverse of the mandril being limited by the height of the
vertical portion of the slot. The top of the sleeve is formed with an undercut groove
made to receive studs or wings which project from a thimble which can be applied to
and removed from the top of the sleeve. The bore of the thimble is less than the bore
of the sleeve but the projecting corner is chamfered so as to present an incline.
When the mandril has been pushed up to the top level of the [ shaped slot and the
thimble is in position a space exists between the two which serves as a chamber to
receive the foundation and facing of the button. The upper part of the press carries
a ram which fits the interior of the thimble and is moved up and down therein
accordingly as the two parts of the press are screwed together or apart. When at

page_text: the bottom of the thimble the ram exerts the pressure requisite to clench the button
together. For example when making a button by my apparatus, the mandril is first
lowered in the sleeve, the metal foundation with its cloth facing is placed in the
sleeve on the upper end of the mandril; the studs or wings on the thimble are
passed into the undercut annular groove through vertical slots and turned. The
mandril is then raised in the sleeve until the pin occupies the top arm of the
[shaped slot, the parts of the button being thus nipped between the top of the
mandril and the chamfered projecting lower edge of the thimble.
The cupped
backing with serrated or other flange is then pushed into the outer end of the
thimble and the two parts of the press screwed together the ram pushing the cupped
backing down the thimble and clenching the parts together by the final pressure.
The press is then unscrewed and the finished button removed. By a modification the
mandril may be raised by a screw thread and held in position by a removable pin
instead of by the shaped slot hereinbefore referred to. In some instances the
pushing home of the cupped back and the clenching might be effected by a punch
instead of by the ram.

Improvements in Apparatus Employed in the Manufacture
of Buttons.
I EMIL BRILL of the firm of Gebrüder Brill of Barmen, Rhenish Prussia in the
Empire of Germany Manufacturers 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 and accompanying drawings
:―
My said Invention relates to apparatus for use in the manufacture of buttons
composed of a metal backing and faced with cloth or other material, such buttons for
example as are referred to in a provisional application for Letters Patent No. 3509
made by me on the 8th day of March 1887 and of which I have since filed a complete
specification. Speaking generally such buttons consist of a metal foundation over
which the cloth covering is placed and a cupped metallic backing which is rivetted or
united by pressure to the said metal foundation the cloth facing being by the same
operation drawn tightly over the front of the button. The cupped backing is or
may be formed with teeth at its periphery, which teeth enter perforations or are
forced into a recess in the foundation clenching the parts of the button together and
securing the cloth covering at the same time. The periphery of the backing may
however be formed without teeth. The apparatus which I use for securing the
component parts of such buttons together and which forms the subject matter of
the present invention consists of a small press mainly composed of two parts capable
of being screwed together and adapted to secure the parts of the button to each
other.
In order that my said invention may be properly understood I will now proceed
more particularly to describe the same with reference to the annexed two sheets of
drawings.
Fig. 1 is partly a side view and partly a vertical section of the lower portion of the
apparatus.
Fig. 2 shows a side view and plan of the thimble which is applied to the part b.
Fig. 3 is the clenching ram.
Fig. 4 is a plan view of the part b.
Fig. 5 is a horizontal section of Fig. 1 at the line C. D.
Fig. 6 is a complete vertical section of the apparatus at the line A. B. Fig. 1.
As shown in these Figs. the apparatus consists of a hollow sleeve b bored to fit a
sliding mandril o which is provided at its outer end with a capstan head or handles u
by which force can be applied to the mandril. The mandril o has also a pin n which
works in a slot of a form, the traverse of the mandril being limited by the height
of the vertical portion of the slot. The top of the sleeve bis formed with an undercut
groove b¹ made to receive studs or wings e² which project from a thimble e which can
be applied to and removed from the top of the sleeve by entering the wings through
the vertical alots 6 and turning the thimble. The bore of the thimble e is less than
the bore of the sleeve but the projecting corner is chamfered so as to present an

page_text: incline as clearly shown in Fig. 6.
When the mandril has been pushed up to the top
level of the shaped slot. and the thimble is in position a space exists between the
two which serves as a chamber to receive the foundations and cloth facing i of the
button. The upper part of the press carries a rain a loosely attached to the part k
by the pine and which fits the interior of the thimble and is moved up and down
therein accordingly as the two parts of the press are screwed together or apart.
When at the bottom of the thimble the ram a exerts the pressure requisite to clench
the button together. For example when making a button by my apparatus, the
mandril o is first lowered in the sleeve, the metal foundations with its cloth facing i
is placed in the sleeve b on the upper end of the mandril o as seen at Fig. 1. The
studs or wings e² on the thimble are passed into the undercut annular groove through
the vertical slots and the thimble is turned-The mandril o is then raised in the sleeve
until the pin occupies the top arm of the shaped slot the parts of the button being
thus nipped between the top of the mandril o and the chamfered projecting lower
edge of the thimble. The cupped backing p with serrated or other flange is then
pushed into the outer end of the thimble and the two parts of the press screwed
together the ram a pushing the cupped backing p down the thimble e and clenching
the parts together by the final pressure, the teeth of the serrated back p being
clenched in the annular groove in the part s. The press is then unscrewed and the
finished button removed. The Figs. on sheet 2 illustrate a modification in the form
of the press. Fig. 7 is a vertical section of the apparatus. Fig. 8 shows the bottom
portion with the mandril o in its lowered position. In this instance the mandril o is
raised by a screw o¹ and is held in position by means of a removable pin d instead of
by the shaped slot hereinbefore referred to. The working of this modified
apparatus will be sufficiently evident from the description already given of the
apparatus illustrated in the first sheet of drawings. The button produced (see
Fig. 10) is slightly different from that shown in sheet 1. A pasteboard backing g
lies behind the cloth facing and a clenching cover z secures the backing f to the
front part of the button. The apparatus may however be used to manufacture any
buttons capable of being secured or clenched together by pressure as described.
Instead of the screwed upper part k shown at Fig. 7 I might employ the ram or
punch shown at Fig. 9 the clenching effect being obtained by striking the ram head
when the parts of the button have been placed in position. By a modification the
mandril may be raised by a screw thread and held in position by a removable pin d
instead of by the shaped slot hereinbefore referred to.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
(1.) The general arrangement and construction of parts comprising the apparatus
for use in the manufacture of buttons of the indicated description substantially as
hereinbefore described and shown.
(2.) An apparatus for use in the manufacture of buttons, consisting of the part b
containing a movable mandril or part o in combination with the thimble e, ram a and
upper part all arranged and acting substantially as described and shown in sheet 1
of the drawings.
(3.) The apparatus for manufacturing buttons shown on sheet 2 of the drawings
either in combination with the part k¹ and ram a or in combination with the detached
ram shown at Fig. 9 of the drawings.
