APPARATUS FOR THE MANUFACTURE OF METALLIC LOOPS OR EYES FOR CLOTH BUTTONS
Year: 1885

page_text: I, CHARLES DENTON ABEL, of No 28 Southampton Buildings, Chancery Lane
in the County of Middlesex, Consulting Engineer and Patent Agent do hereby
declare the nature of my invention for "APPARATUS FOR THE MANUFACTURE
OF METALLIC LOOPS OR EYES FOR CLOTH BUTTONS" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to apparatus for the manufacture of metallic loops or eyes
for cloth buttons, the construction of which will be readily understood on reference
to the accompanying drawings in which Fig. 1 shews a sectional elevation, and
Fig. 2 a plan of the apparatus.
The apparatus consists of a press B E in combination with a perforating
apparatus C. The plate m to be fixed on the underside of the cloth buttons has a
deep bulge n formed at its centre and in addition a concentric circular corrugation,
both of which are formed by a preliminary operation with suitable dies. This
plate m is placed upon the matrix a of the bed E, having precisely the same
configuration, so that when the correspondingly formed die B, actuated by the
lever b pivotted at d, is forced down on the plate m, this is held securely at all
points between die and matrix. The bed E is arranged as follows. It consists of
a cylinder on the lower part of which a beam C is mounted on an axis D which
beam receives a rocking motion by means of a lever F shewn in dotted lines at
Fig. 1. The cylinder E has a central bore hole in which slides a pin g, resting on
one arm of a lever e whose other arm projects laterally through a slot in the
cylinder. On depressing this arm of the lever the inner arm raises the pin g. A
spring f presses the inner arm of the lever downwards, and thus prevents the pin g
from projecting into the recess of the matrix unless forced up by the lever. This
pin g serves to throw the plate m out of the matrix when the operation has been
completed. The matrix has two lateral holes i formed in it, opening into the
recess, so that on rocking the beam C by means of the lever F, the punches or.
perforators co carried by the former are caused to pass through the holes i and to

page_text: perforate the bulge n of the plate m so as to form this into a loop or eye by means
of which the button can be sewn on.
During the perforating operation the die B is held down upon the plate so that
this cannot give way while the punches are being forced into it, except at the
points where the holes are punched in.
.
On completion of the perforations the die B is raised and the lever e is depressed
so as to throw out the plate by means of the pin g.
The plate m so formed is then inserted into the hole of the base o of the button,.
as shewn at Fig. 3, and is secured by the filling of the button, consisting of paper,
cement &c, whereupon the metal casing with the cloth covering is fixed on in the
well known manner.
The perforation of the plate m can also be effected after it has been attached to
the button, the die B being formed in a corresponding manner to fit over this.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The construction of apparatus for forming metallic eyes or loops on cloth
buttons by forming holes in a plate m, consisting of the die B actuated by lever b,
the matrix a having two lateral holes, between which two parts is held the plate m
previously formed with a bulge n and concentric corrugation h; the matrix bed E
with longitudinal boring, pin g for removing the plate from the matrix by means of
the lever e, and the beam C with punches c actuated by lever F, all arranged and
operating substantially as herein described.
