PROVISIONAL SPECIFICATION.
Improvements in Button Fasteners and Apparatus for Securing
the same.
I, WILLIAM EDWARD STROETZEL of 6 Arnold Road Tooting in the County of
Surrey, Agent do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in that class of setting devices which are
adapted for attaching buttons to fabrics or other materials by means of a metallic
fastener or connection.
According to my invention I employ a setting instrument the upper jaw of which
is provided with a curved recess against which the point of the metallic fastener
which is held in the lower jaw may be deflected or bent over.
The fastener I employ is an ordinary headed wire nail or pin of brass or other
suitable material and with which may be connected a washer or disc of metal,
leather or other suitable material.
The lower jaw consists of a perforated cylinder resting on a spring which rests
on a solid bottom. From this solid bottom rises a pin or projection corresponding
with the hole of the cylinder into which it enters so far that when the cylinder is
pressed down as far as the spring will allow then the pin or projection is level with
the upper surface of the cylinder.
The nail or fastener is inserted in the hole of the cylinder so as to rest on the
pin aforesaid.
In operating the device the button is pushed on to the upper jaw so that the
shank is crosswise relatively to the curved groove made on the underside of the
upper jaw, the nail is placed in the hole of the cylinder in the lower jaw and if a
washer is used it is placed on the top of the cylinder from which the nail point
issues.
The fabric or material to which the button is to be attached is now inserted
between the two jaws and by depressing the handles the jaws are closed together
whereby the nail becomes bent round the shank of the button.

COMPLETE SPECIFICATION.
Improvements in Button Fasteners and Apparatus for Securing
the same.
I WILLIAM EDWARD STROETZEL of 6 Arnold Road Tooting in the County of
Surrey 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 :-
This invention relates to means for attaching buttons to fabrics or other
materials, as fully illustrated in the accompanying drawings and hereinafter
explained.
For the purpose of carrying my invention into effect I employ a setting stamping
or punching, instrument as generally employed where two dies are to be forced
against each other. Such instruments are well known and may take the form of
parallel pliers or may be made to work with a hand lever or foot treadle or
otherwise.

page_text: According to my invention I provide such instruments with dies of peculiar con-
struction, and in the drawings
Fig. 1. represents the upper die. with a shank button in position.
Fig. 1 the same with a hole button in position.
Fig. 1B is a top view of die shewing springs for holding button in position.
Fig. 2. is a vertical section of lower die with collar and fastener pin in
position.

Fig. 2 is a plan of the collar or shield.
Fig. 2 represents the fastener piu.
Fig. 3 shews the completed fastening of a shank button.
Fig. 4 shews the same of a hole button.
The lower die employed for the purpose of carrying my invention into effect is
illustrated in Fig. 2 and consists of a cylinder a in the centre of which is fixed a
piston which fits the bore of a second cylinder d that fits into cylinder a.
Cylinder d may be provided with a guide grooved while a guide pin may be
passed through a. Cylinder d is supported by a spiral spring e so that it is at rest
at the highest point allowed of by guide pin d. In the top of cylinder d is a recess
which forms a seat for a collar e shewn in plan in Fig. 2.
The metallic fastener employed is a common pin or grip pin as shewn in Fig. 2B
and in operation this pin is placed head downwards resting on piston b as shewn in
Fig. 2.
of a
The upper die (Fig. 1.) is provided with a grooved curve and is made beak
shaped so as to permit the die either to enter the shank button as shewn in
Fig. 1. of the drawing, or to dip into the indentation of a hole button as shewn in
section in Fig. 1A and in top view in Fig. 1B. Springs 7 may be employed for
holding the button in position.
On forcing the dies together the point of fastener pin h pierces the fabric cloth
leather or other material which will have been inserted between the dies strikes the
curve on one side of the shank g, bends over in accordance with the shape of the
curve, gradually forming a loop round the shank doubling back into the cloth or
other material, the fastening being thus complete as shewn in Fig. 3 of the drawing
in which indicates the fabric, the other letters denoting the same parts as before.
In hole buttons, placed relatively to the die as shewn in Figs. 1A and 1B the
fastener pin passes through one of the holes m bends over along the curve and
doubles back through another hole. The tendency of the pin in bending would be
to push the button away, which is prevented as regards one direction by the beak
shaped point of the die dipping into the indentation while a shoulder s on the die
acts in the same way as regards the opposite direction. The finished fastening of a
hole button is shewn in Fig. 4.
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.) In a device for fastening buttons to fabric, leather or other materials the
combination of a suitable pin (as h) and a collar (as e) and means for deflecting
and bending the pin around a part of the button substantially as described and
shewn in the drawings.
2.) In an apparatus for fastening buttons to fabric leather or other materials
by means of a metal fastener the arrangement of a die shaped to enter the shank
of shank buttons or to dip into the indentation of hole buttons substantially as and
for the purpose described and illustrated by the drawings.
Dated this 10th day of October 1892.
