DELCIFICATION,
I HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my Invention for "IMPROVEMENTS RELATING TO THE FASTENING OR SECURING
OF BUTTONS OR SIMILAR ARTICLES" 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 buttons and analogous devices, designed to be attached
to garments by means of metal fastenings, and comprises a button or similar
contrivance with a solid face having a device to deflect or upset the bifurcated or
other prongs of a metal rivet or fastener, in combination with a fastening device
having two or more sharpened prongs consisting of longitudinal sections or portions
of a hollow cylinder and provided with a head, as hereafter described.
In the accompanying Drawing:
Figure 1 is a vertical section of a button or rivet head, and an elevation of a
fastener therefor constructed according to this Invention.
Figure 2 is a vertical section of a button and fastener when attached to a
garment.
Figure 3 is a plan of a piece of fabric showing a rivet in cross section.
Figure 4 is an elevation of a fastener showing the throat.
Figure 5 is a plan of the same.
.
Figure 6 is an elevation of a fastener without a throat.
Figure 7 is a plan of the same.
Figure 8 is an elevation of fastener with the throat extending to the head of
the same.
÷
Figure 9 is an elevation of an unthroated rivet with prongs extending to head.
Figure 10 is a vertical section of a button with a separately. inserted deflecting
device, and an elevation of a rivet.

The object of this Invention is to combine with a button or rivet head or similar
contrivance having a solid face, a metal fastening device which shall have two or
-

page_text: more sharpened prongs, consisting of sections or portions of a hollow cylinder, and
a head, so that the sharpened ends or points of the prongs can, without much effort,
be forced through the material of a garment or other article and then upset by a
deflecting device fixed' to or within the inner surface of the shell of a button or
rivet head.
To properly combine a metal button or rivet head with a sharpened pronged
fastening device, I construct the button or rivet head A with a conical depression a
formed in its shell, or by placing within the shell of the button or rivet head any
suitable device or contrivance that will answer the purpose designed, whether this
contrivance form part of the button shell or whether it be merely inserted within
the same.
A fastening device C is next constructed, and this device may have two or more
prongs b consisting of sections of a hollow cylinder; the prongs however under all
circumstances must be sharpened and provided with a suitable head c; this head
is preferably integral with the prongs but it may be attached to the base of the
prongs in any suitable manner.
When the button or rivet head and its fastening device are constructed
substantially in the manner herein before described, the button is attached by first
thrusting the sharpened prongs b through the fabric, until the prongs protrude on
one side of the fabric and the head c lies closely against the other side. A. button
or rivet head A with a solid face is then placed so that the sharpened ends of the
prongs will be received within the shell of the button or of the rivet head and in
contact with the cone or other device a. Suitable pressure being applied to the
button or rivet head the sharpened ends of the prongs bare upset or turned
outwards by the action of the cone or upsetting device in the button shell, which
cone, entering between the prongs, curves them outwards to an extent greater than
the diameter of the orifice in the button shell through which they originally
entered, thereby uniting the button or rivet head as the case may be firmly to its
metal fastener, and tightly holding the fabric clamped between the head of the
fastener and the hub of the button or under surface of the rivet head.
To facilitate the thrusting of the fastening device through the fabric and at the.
same time to more perfectly secure or fix the fastening device to the fabric, it will
be advantageous to form a space d at or near the base of the sharpened prongs b.
This space consists substantially of a throat, into or across which lies a strip of the
fabric when the prongs are thrust through it, and this strip acts as a tie in
conjunction with the fabric which is clamped between the inner surface of the
head c and the button or rivet head as before described.
The advantage derived from making the sharpened prongs from a hollow
cylinder is that the curvature of the inner and outer surfaces of the prongs renders
them stiffer and less liable to bind when thrust through the fabric, and causes them
to upset or flare outwards with greater certainty. when in contact with the
deflecting device, than would otherwise be the case.
I do not desire to claim the particular construction of the fastening device
herein before described, for that has been substantially described and claimed in.the
Specifications of United States Patents Nos 247088 and 251265 granted to Edward
Maynz; nor do I desire to claim broadly a button head with an interior. deflecting
device combined with pronged fastener, for such is described in the Specifications of
United States Patents Nos 197959, 200018, 207706 granted to. Charles E. Bates,
but the Bates fasteners were merely flat sided prongs stamped from sheet metal,
and the buttons generally had perforated faces.

"
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:
it
First. The combination of a headed fastening device, provided with two or more
sharpened prongs, consisting of longitudinal sections of a hollow cylinder, and a
solid faced button or rivet head, with an upsetting device within the shell of the
said button, as, and for the purpose, described.

page_text: Second. The combination of a solid faced button or rivet head having an interior
upsetting device, with a metal fastener having two or more sharpened prongs
consisting of longitudinal sections of a hollow cylinder, a head, and a space or
throat d, as and for the purpose described.
