Improvements in Hollow Rivets or Eyelets for Fastening Buttons and
in the Method of Manufacturing the said Rivets or Eyelets.
We, WILLIAM CLARK PLAYER of 109, Newhall Street, in the City of Birming-
ham, Manufacturer, and ARTHUR VERNON BAYLISS, of Riverdale, Mary Road,
Stechford, in the County of Warwick, Tool Maker, do hereby declare the nature
of this invention to be as follows.-
-
This invention has reference to those hollow vets or eyelets which are used
for fixing buttons to garments and other articles A hollow vet or eyelet of the
kind to which this invention relates has an enlarged projecting flange or collar
about midway between its ends, this flange or collar forming a bearing for the
back of the button which turns on the hollow rivet or eyelet and 18 there secured
by the front end of the hollow rivet or eyelet being spread over at the front of the
button. The other part of the hollow rivet or eyelet at the back of the button is
passed through the material which is gripped between the said collar and a washer
which latter is secured on the rivet or eyelet by the end of the vet or eyelet being
spread over
Heretofore a hollow 11vet or eyelet of this kind has been made in two parts
joined together at the collar oi Hange According to this invention we make
the said hollow rivet or eyelet in one piece of metal as we will now describe
thereby reducing the number of processes in the manufacture and producing a
better and cheaper article than heretofore
In carrying out this invention we take a cucular ductile sheet metal blank of
suitable diameter and by successive operations in suitable dies in a press or
other suitable machine we raise this blank into the form of a cylinder which 18
somewhat longer than the required hollow 11vet or eyelet and is closed at one end
and for about one half, more or less, of its length from the closed end is reduced
in diameter. In the next process we employ a pair of dies of which the bottom die
has a circular 1ccess of the proper size to receive the reduced closed ended part
of the cylinder and the top tool has a cucular recess of the proper size to receive
the open ended part of the cylinder on which the button is to turn The central
part of the cylinder where the flange is to be formed 18 thus unsupported so that
as the top tool descends the cylinder is upset or crushed endwise which bulges
out the central part and thus forms the required flange of double thickness of
metal
The hollow vet or eyelet is now finished except that the closed end of the
cylinder 18 01 may be punched out which can readily be done either before or
after the hollow rivet or evelet is fixed on the button What we prefer 18 to
punch out the closed end of the hollow 11vet or eyelet simultaneously with fixing
the rivet or eyelet to the button This 18 accomplished by placing the button in
position on the hollow rivet or eyelet the said button and the hollow 11vet or
eyelet being supported in a suitable bed or bottom tool. The punch is made

page_text: with a shoulder at the proper distance from its end so that when the punch descends
the said shoulder on the punch spreads out the open end of the vet or eyelet over
the hole in the button and thus secures the button thereto at the same time that
the lower end of the punch punches out the closed end of the cylinder ready for
spreading the same over the washer in fixing the vet or evelet to the material.
It is to be understood that if desired the said vet or eyelet may be made and
used with one end closed, that is to say, the closed end will not be punched out.

Improvements in Hollow Rivets or Eyelets for Fastening Buttons
and in the Method of Manufacturing the said Rivets or Eyelets.
We, WILLIAM CLARK PLAYER, of 109, Newhall Street, in the City of Birming-
ham, Manufacturer, and ARTHUR VERNON BAYLISS, of Riverdale, Mary Road,
Stechford, in the County of Warwick, Tool Maker, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement..
This invention has reference to those hollow livets or eyelets which are used
for fixing buttons to garments and other articles A hollow rivet or eyelet of the
kind to which this invention relates has an enlarged projecting flange or collar
about midway between its ends, this flunge or collar forming a bearing for the
back of the button which tuins on the hollow vet or eyelet and is there secured
by the front end of the hollow vet or eyelet being spread over at the front of the
button The other part of the hollow livet o eyelet at the back of the button 18
passed through the material which is gripped between the said collar and a washer
which latter is secured on the 11vet or eyelet by the end of the vet or eyelet being
spread over.
Heretofore a hollow vet or evelet of this kind has been made in two parts
Joined together at the collar or flange According to this invention we make
the said hollow 11vet or eyelet in one piece of metal as we will now describe
- thereby reducing the number of processes in the manufacture and producing a
hatter and cheaper article than heretofore.
Our invention 18 illustrated by the accompanying drawings on which Fig 1
18 a sectional elevation and plan of a hollow 11vet or eyelet constructed according
to this invention attached to a button; Fig 2 shews a metal blank from which
the hollow rivet or eyelet has been formed, Figs. 3, 4, 5 and 6 illustrate suc-
cessive stages in the manufacture of the hollow rivet or eyelet shewn by Fig 1
from the blank illustrated by Fig. 2; Figs 7 and 8 are sectional elevations of the
tools for performing one of the operations in the manufacture of the hollow rivet
01 evelet Figs 9 and 10 are sectional elevations of the tools for performing
another stage in the manufacture of the said hollow rivet or eyelet, Figs. 11
and 12 are sectional elevations of the tools for piercing the hollow rivet or eyelet
and securing the same to the button
The same letters of reference indicate the same or corresponding parts in all
the figures.
In carrying out this invention we take a circular sheet metal blank of suitable

page_text: diameter such as shewn in Fig. 2 and by successive operations performed in
suitable dies in a press or other suitable machine we raise this blank into the
form of a cylinder A such as shewn by Fig. 5 which is somewhat longer than the
required hollow livet o eyelet A (Fig 6) and is closed at one end a¹ and for about
one half more or less of its length from this closed end that is at a³, this
cylinder A is reduced in diameter forming a rounded shoulder a³, from which
to the open end at the cylinder 18 somewhat taper that is to say, the open end at
18 somewhat smaller in diameter than the shoulder pait a This formation of
The flat
the cylinder as shewn in Fig. 5 can readily be obtained as follows
sheet metal blank (Fig 2) 16 first raised into the shallow cup Fig 3 made with
tape sides by dies such as are well known and then drawn through to the shape
represented by Fig 4 which is a body with a closed end a' and parallel sides Tho
hollow body represented by Fig. 4 is then operated on by the fools represented by
Figs. 7 and 8 where it will be seen that the bottom tool C has a circular 1ccess
corresponding with the taper part of the cylinder Fig 5 from the shoulder a³ to
the open end a', and the top tool D has a central recess d¹ shaped to correspond
with the 1ounded end a¹ of the cylinder and the reduced part and shoulder a³.
In the centre of the bottom tool there is a vertical pin E to carry the cylinder in
an inverted position as shewn in Fig. 7 this pin being acted upon by a spring F
in the bed G to which the bottom tool C 18 fixed When the top tool D descends
(see Fig. 8) the cylinder A 18 compressed between the top die D and the bottom
die C and is forced into the recess c¹ in the bottom die thereby reducing the
diameter of the open mouth a' and at the same time the upper part at as of the
cylinder is reduced in diameter so as to form a shoulder so that when the
cylinder A leaves these dies it has the form represented by Fig 5
In the next process we employ a pair of dies marked H and I (see Figs. 9 and 10)
of which the top die H has a circular recess h¹ of the proper shape and size to
receive the reduced closed ended part as of the cylinder A and the bottom tool I
has a cucular recess of the proper size to receive the open ended part at of the
cylinder on which the button is to tuin This bottom die I has a central pin L
to carry the cylinder A and to force it out of the bottom die this pin is operated by
6 treadle or other well known means. The cential part of the cylinder A
where the flange a is to be formed is thus unsupported so that as the top tool H
descends the cylinder A is upset oi crushed endways which bulges out the central
part a and thus forms the requied flange a of double thickness of metal as
shown by Figs 1, 6, and 10 The hollow livet or eyelet has now the appearance
represented by Figs 6, and 10 and it is finished except that its closed end a¹ 18 or
may be punched out which can readily be done before or after the hollow rivet
1s fixed on the button What we prefer is to punch out the closed end a' of the
hollow rivet or eyelet simultaneously with the fixing of the vet or eyelet to
the button B. This is accomplished (see Figs. 11 and 12) by placing the button B
in position on the hollow rivet or eyelet A which latter is supported in the bed or
bottom tool J in which the part as of the hollow livet or eyelet fits. This bed or
bottom tool J has a central hole of about the same size as the requned hole in
the open end a of the hollow rivet or eyelet Above the bed J is a punch K of the
proper size to pierce the hole in the hollow vet or eyelet and this punch is made
with a hollow shoulder at the proper distance above the lower end so that
when the punch K descends the lower end of the punch punches out the closed
end a³ of the hollow rivet or eyelet A ready for spreading the same over the washer
and fixing the rivet or eyelet to the material and at the same time that the end a*
1s punched out the shoulder A on the punch spreads out the open end at of the
rivet or eyelet over the hole in the bottom B and thus secures the button to the
hollow rivet or eyelet as shewn in Figs 1 and 12.
It is to be understood that if desired the said rivet or eyelet may be made and
used with the end a closed instead of being open that is to say the closed end a¹
will not be punched out.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim 15.-
1 The manufacture of a hollow 11vet o eyelet of the kind herem referred to,
for fastening buttons, from one circular sheet metal blank by successive operations
in dies which form the blank into a cylindrical shape with a closed end or with
both ends open and ultimately bulge out the sides and compress the bulged part
forming & flange a³ of double thickness of metal somewhere about midway between
the ends of the hollow rivet or eyelet, substantially as set forth
2. A hollow rivet or eyelet of the kind herein referred to, for fastening
buttons, formed from one circular sheet metal blank raised to a cylindrical form
and having its sides bulged out and compressed so as to form a flange a³ of
double thickness of metal somewhere about midway between the ends of the hollow
rivet or eyelet substantially as set forth
