IMPROVEMENTS RELATING TO LACING HOOKS OR STUDS FOR BOOTS AND SHOES, ALSO APPLICABLE TO FASTENERS FOR GLOVES OR OTHER ARTICLES
Year: 1885

page_text: I, BARTOLO LEOPOLD D'AUBIGNÉ of Knowle, in the County of Warwick
Manufacturer, do hereby declare the nature of my invention for "IMPROVEMENTS
RELATING TO LACING HOOKS OR STUDS FOR BOOTS AND SHOES, ALSO APPLICABLE
TO FASTENERS FOR GLOVES OR OTHER ARTICLES" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
My invention relates chiefly to lacing hooks or studs for use on boots, shoes,
gloves and other articles.
The said invention comprises improvements in that class of lacing hooks or studs
which are formed from pieces of solid metal rod or wire, and which are provided
with shanks adapted to be inserted through the leather or other material, and
rivetted or clinched over the same to secure them in place.
The said lacing hooks or studs are formed with flanges or collars which bear
upon the outer surface of the leather or other material, and the shanks are rivetted
or clinched over the inner surface thereof so that the said material is held between
them and the flanges or collars.
.
The said improvements are also applicable to other fastening devices designed
for use on gloves or other articles and formed with similar shanks and flanges or
collars.
In the use of these lacing hooks or fastening devices great inconvenience has
been caused by the cutting of the leather or other material around the edges of
the flanges.
This cutting sometimes occurs in the act of rivetting the hook, stud or fastener
in its place, but, if it should not occur in this operation, it soon takes place in use,
so that in a very short time the lacing hook, stud or fastener becomes detached
from the boot, shoe, glove, or other article on which it has been applied. And as
the rivetting is frequently effected in such a manner that the rivetted or turned
down end of the shank extends beyond the flange which forms the rivet-head, there
are two edges tending to cut the leather or other material.

page_text: According to my invention I provide means for obviating these defects as follows,
that is to say-I construct such hooks, fasteners, or like devices, as shown in the
accompanying drawing, in which,
Figure 1 is a side view of a lacing hook.
Figure 2 is a central transverse section of the same.
Figures 3 and 4 are similar views of a button or fastening device for gloves or
other articles.
Figures 5 and 6 are similar views illustrating a modification of my said
invention.
Like letters indicate the same parts throughout the drawing.
a is the shank of the device and b is the head. c is the flange or collar which is
designed to bear against the outer surface of the material when the device is in
place. The shank a is drilled longitudinally, preferably only as far as the flange c
as shown, in order to make it tubular.
Instead of making the flange or collar c flat on its underside, so that it presents
a sharp corner or cutting edge to the leather or other material with which it is in
contact, when the hook or fastener is rivetted in its place, I make the underside of
the said flange or collar curved, as shown at c¹ in Figures 1 and 2, or bevelled or
inclined as at ca in Figures 3 and 4, thereby avoiding the existence of the said sharp
corner or cutting edge.
In some instances I curve or round the edge of the flange or collar, as at c³ in
Figures 5 and 6, without making the underside bevelled or inclined, but I usually
prefer to adopt the inclined or bevelled formation under the flange or collar.
In the modification of my invention shewn in Figures and 6, the shank a is
made taper externally, so that the hole formed in the material to receive the lacing
hook or fastening device can be made smaller, and consequently the retention of
the said device in the material more effectually ensured than when the shank is
made parallel. This form also affords the advantage that the shank can be rivetted
or clinched more readily than would otherwise be practicable.
In some instances I so proportion the length of the shank to the diameter of the
flange, that when the said shank is rivetted down or clinched over the leather or
other material, it will not extend beyond the edge of the flange; I thus prevent any
cutting action by the edge of this rivetted or turned over portion of the metal.
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
First. In a lacing hook, stud or other fastening device made from a solid piece
of metal rod or wire and having a tubular shank and a flange or collar as above
described, the bevelled, inclined, or curved formation of the underside of the said
flange or collar, substantially as, and for the purpose, specified.
Second. The modification of my invention wherein the shank is tapered externally
as shewn in Figures 5 and 6 of the drawings, for the purpose specified.
