Improvements in Covered Fastening Devices.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co. Patent.
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby declare
the nature of this invention to be as follows:-
My invention relates to a great variety of fastening devices and parts thereof
such as eyelets and lacing studs for boots and shoes that are covered in whole or in
part with various compounds, such as celluloid or rubber, for example; and the
objects of my invention are to facilitate the manufacture of these covered fasteners
and to secure an improved product.
My invention consists, broadly, in a fastener-body formed with a flange having,
on its under side, supporting-feet which are within the perimeter of the flange;
and also, broadly, in the combination of a fastener-body of said characteristics
with a covering of any desired compound, the covering gripping the head of the
body around its whole edge, and extending over and under the edge, so that the
shell-like covering is permanently anchored or locked on the head, and made more
durable than heretofore. A subordinate feature of my invention lies in perforating
the supporting feet, so that the compound on the outside of the flange
with compound on the inside of the fastener-body by portions of the compound
lying in the perforations through the feet, these bonds or unions between the
outside and inside deposits of covering compound forming part of the outside and
inside deposits of covering material, and being within the perimeter of the covered
article.
united
My invention comprises a fastener-body, by which term I mean, any article or
thing to be covered, in whole or in part, with a covering compound; and a flange
on both sides of which the covering compound is placed. In the course of
manufacturing fastening devices of this class, I have discovered that in order to
facilitate the manufacture and to turn out a more durable product, it is necessary
to have the under side of flange some distance above the supporting die when the
plastic cover is pressed on by the facing die because the pressure exerted by the
facing die tends to force the under surface of flange against the face of the supporting
die, and prevent the composition from getting well under and against the under
surface or under margin of the flange. By means of the supporting feet from the
under face of flange, the under face of said flange is kept at a proper practical
height above the face of the supporting die during the homing of the facing die,
to allow a proper flow of the compound under and against the under face of flange,
the feet keeping flange above the opposed surface of the die. I have also discovered
that in order to secure the strongest and most enduring hold of the plastic or like
covering compound on body it is necessary to preserve the integrity of flange ;
that is, to keep the flange intact along its outer edge; the edge of the flange
projecting beyond the feet, so that the compound may fill in under the flange, and
between the feet. For this reason, the supporting-feet are projections from the
under side of the flange, within the perimeter of the flange, so that the compound

page_text: may fill in between the feet and underneath the whole edge of the flange.
I preferably slit or perforate the feet, so that the covering compound within and
without the flange may be united or bonded together by portions of the compound
in and through the slits or perforations, but this is a minor feature of my invention,
although the bonding is desirable in that it tends to insure the permanency of
the covering. The slits or perforations, if desired, are readily produced by the
die used for throwing down the supporting feet. If perforated feet are desired a
sharp pointed die is employed, but if non-perforated supporting feet are preferred,
a dull pointed die is used in formation of the supporting feet. By the term
"bases" herein I mean the portions of the feet when the feet spring from the
flange.
I am fully aware of the existence of a large number of prior Letters Patent
which describe covered fasteners, and I ani also aware of the fact that the mere
structural differences between my new covered fasteners and some covered fasteners
that have been heretofore made are of such a character as to be inconspicuous to
the superficial observer in the ordinary small sizes such as are used on shoes, for
example. But the novel features herein described as characteristic of my invention,
are the results of long study and many experiments made by me, as a manufacturer
of covered fastener devices, for producing a covered fastener device which
should be strong and durable when used and which should be economical to
manufacture.
The commercial success of this class of fasteners composed of metal bodies and
tops of plastic material pressed and moulded in place, depends wholly on getting
the covering into a small space and securely anchoring or locking it, mechanically;
for these coverings of plastic material will not keep in place, properly, unless they
are held in place mechanically and not by mere adhesion as commonly supposed.
After the coverings have been pressed and moulded in place on the metallic bodies,
they become hard and dry and cease to adhere or stick to the metal, but become a
little loose, so that they may be compared to shells or shucks. Therefore it is that
the coverings should be held in place mechanically, and this I accomplish by the
construction and arrangement of the supporting-feet and projecting flange over and
under the whole of which the plastic covering is forced, entirely around the edge
and under surface of the flange, and at all points thereof.

I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 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:-

that the compound on the outside of the flange is united with compound on the
inside of the fastener-body by portions of the compound lying in the perforations
through the feet, these bonds or unions between the outside and inside deposits of
covering compound forming part of the outside and inside deposits of covering
material, and being within the perimeter of the covered article.
In the accompanying drawing,
Figure 1 is a top-plan view, and
Figure 2 is a side view of one form of fastening device, namely, an eyelet,
embodying my invention, on a greatly enlarged scale, and without the covering, for
the sake of greater clearness.
Figure 3 is a central vertical section of the eyelet shown in Figures 1 and 2 with
the covering.
Figure 4 is an enlarged view, in cross-section, of eyelet and covering dies, this
view particularly illustrating the main function of the supporting feet with which
the fastening devices embodying my invention are provided.
Figure 5 shows my invention embodied in a lacing stud, and
Figure 6 shows the same embodied in a button.
The drawing shows my invention in the best form now known to me in which 1 is
a fastener-body, by which term I mean, any article or thing to be covered, in whole
or in part, with a covering compound; and 2 is a flange on both sides of which the
covering compound is placed. In the course of manufacturing fastening devices of
this class, I have discovered that in order to facilitate the manufacture and to turn
out a more durable product, it is necessary to have the under side of flange 2 some
distance above the supporting die (see D, Figure 4) when the plastic cover 3 is
pressed on by the facing-die (see D', Figure 4) because the pressure exerted by the
facing die Di tends to force the under surface of flange 2 against the face of the
supporting die D', and prevent the composition from getting well under and against
the under surface or under margin of the flange. By means of the supporting
feet 4 from the under face of flange 2, the under face of said flange 2 is kept at a
proper practical height above the face of the supporting die (see Figure 4), during
the action of the facing die, to allow a proper flow of the compound under and
against the under face of the flange 2, the feet 4 keeping flange 2 above the
opposed surface of the die D. I have also discovered that in order to secure the
strongest and most enduring hold of the plastic or like covering compound on
body 1, it is necessary to preserve the integrity of flange 2; that is, to keep the
Hange intact along its outer edge 5; the edge of the flange 2 projecting beyond
the feet 4, so that the compound may fill in under the said flange 2, and between
the feet 4. For this reason, the supporting-feet 4 are projections from the under
side of the flange, within the perimeter of the flange, so that the compound may
fill in between the feet and underneath the whole edge 5 of the flange 2. prefer-
ably slit or perforate the feet 4, as at 6, so that the covering compound within and
without the flange may be united or bonded together by portions of the compound
in and through the slits or perforations, as at 7, but this is a minor feature of my
invention, although the bonding is desirable in that it tends to insure the
permanency of the covering. The slits or perforations, if desired, are readily
produced by the die used for throwing down the supporting feet. If perforated
feet are desired a sharp pointed die is employed, but if non-perforated supporting
feet are preferred, a dull pointed die is used in formation of the supporting-feet.
By the term "bases" herein I mean the portions of the feet when they spring from
the flange.
I am fully aware of the existence of a large number of prior Letters Patent which
describe covered fasteners, and I am also aware of the fact that the mere structural
differences between my new covered fasteners and some covered fasteners that have

page_text: been heretofore made are of such a character as to be inconspicuous to the super-
ficial observer in the ordinary small sizes such as are used on shoes, for exampie.
But the novel features herein described as characteristic of my invention are the
results of long study and many experiments made by me, as a manufacturer of
covered fastener devices, for producing a covered' fastener device which should be
strong and durable when used and which should be economical to manufacture.
The commercial success of this class of fasteners composed of metal bodies and
tops of plastic material pressed and moulded in place, depends wholly on getting
the covering into a small space and securely anchoring or locking it, mechanically;
for these coverings of plastic material will not keep in place; properly, unless they
are held in place mechanically and not by mere adhesion as commonly supposed.
After the coverings have been pressed and moulded in place on the metallic bodies,
they become hard and dry and cease to adhere or stick to the metal, but become a
little loose, so that they may be compared to shells or shucks. Therefore it is that
the coverings should be held in place mechanically, and this I accomplish by the
construction and arrangement of the supporting-feet and projecting flinge over
and under the whole of which the plastic covering is forced, entirely around the
edge and under surface of the flange, and at all points thereof.
Having now particularly described and ascertained the nature of the said inven-
tion 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. As a new article of manufacture; a fastener-body formed with a continuous
flange which has supporting feet projecting from its under side within the perimeter
of the flange, substantially as and for the purpose set forth.
Second. As a new article of manufacture, a fastener-body formed with a flange
which has supporting-feet projecting from it's under side within the perimeter of the
flange, the edge of the flange projecting beyond the bases of the feet, substantially
as and for the purpose set forth.
Third. As a new article of manufacture, a fastener-body formed with a flange
which has perforated supporting-feet projecting from its under side, within the
perimeter of the flange, substantially as and for the purpose set forth.
Fourth. As a new article of manufacture, a fastener body or lastener member,
comprising a body formed with a flange having supporting-feet projecting from its
under side, within its perimeter, combined with a plastic covering within and
without the flange and holding on the flange between the feet, substantially as and
for the purpose set forth.
Fifth. As a new article of manufacture, a fastener or fastener member, comprising
a body formed with a flange and with supporting-feet from the flange, within the
perimeter of the flange, the edge of the flange projecting beyond the bases of the
feet, combined with a plastic covering within and without the flange and holding on
the flange between the feet, and on the portion of the flange which projects beyond
the bases of the feet, substantially as and for the purpose set forth.
Sixth. As a new article of manufacture, a fastener or fastener member, comprising
a body formed with a flange and perforated feet dependent from the flange within
the perimeter thereof combined with a plastic cover within and without the flange
and through said perforations, substantially as and for the purpose set forth.
