Improvements in and relating to Fasteners for the Waistband of
Pantaloons and similar Garments.
A communication from ISAAC BLUM, of No. 113, West Baltimore Street, Baltimore,
State of Maryland, United States of America, Gentleman.
1, PETER JENSEN, Fellow of the Institute of Patent Agents, of 77 Chancery Lane,
in the County of London, 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:—
The invention relates to a new and improved fastening for meeting parts of
garments and is specially intended for application to the coupling of trousers in the
front, at or near the waistband where the two sections of the fly are fastened
together.
When such article of wearing apparel is upon the person the fastening around the
waist is subjected to great strain and tension; it is desirable to remove such strain
from the buttoned fly as much as possible, therefore it is necessary to place at or near
the juxtaposing free ends of the waistband a meshing device of great strength, of
minimum weight, easy of connection and disconnection.
With these objects in view my invention consists in a device which I herein
denominate a fly-clasp composed of metal, light in weight, by which the required
results are attained all as herein fully described, illustrated in the drawings and
specifically pointed out in the claims.
Referring to the accompanying drawings wherein like letters of reference point out
similar parts on each figure,
Figure 1, represents the upper portion of a pair of trousers opened, supplied with
my improved fly-clasp.
Figure 2, is a detail view of the hook plate shown flat and folded.
Figure 3, is a view of the blank from which the hasp of the clasp is constructed
when intended to be folded over.
Figure 4, is a top plan view of said hasp folded over.
Figure 5, is an edgo view of Figure 4.
Figure 5, represents a hasp made of a single strip, showing opposite ends of
preferred form for making connections to fabric.
Figure 6, is a view of the two members of the fly-clasp connected to fabric, parts
being broken away, showing the manner of attachment thereto.
In the drawings, A, represents the hook member of the device which consists of a
flat piece of metal the lower portion of which, a, is practically an elongated triangle
reaching from the dotted line, e, e, to apex, al, from said dotted line forwardly is an
outwardly carved section, a². The plate is provided with an oviform opening, a³,
through which portions of the fabric of the garment will be pressed when the clasp
is interlocked in the manner presently set forth.
The curved section, a², of the plate, A, in practice is turned and folded over
parallel with the plane of the plate. In order that the hooked plate may be main-
tained rigidly attached to the fabric, I provide in addition to perforations, 1, a
series of recesses or notches, 2, on the edges of each of the members of the device
whereby when sewed on, as illustrated in Figure 6, there will be no risk of its sliding
or moving in any direction.
B, represents the hasp or staple consisting of base strips, b, b, integrally conjoined
and adapted to be folded over each other along the dotted line, Figure 3, thus making
a smooth rounded edge, b, to receive the hook of the plate, A, without any friction.
The preferable form of the spears extending from the base strip. 1, is shown in
Figure 5, which consists, as will be seen, of an integral shield shaped piece, 5,

page_text: carrying segmental extremities, 4. thus providing a notch or recess. 5. When thread
is passed over the spear it will fall within said notch, and as tension is applied to the
hasp the threads will be kept from slipping off by reason of the abutments, of the
segments 1.
Extending outwardly from either end of the base strips, b, of the staple, B, are
pointed spears, ², provided with edge notches, 2, for receiving turns of the thread
used for permanent attachment of the staple to the garment fabric. The spears of
the staple are passed through the cloth and then two are extended in opposite
directions outwardly, while the other two are returned towards each other, sec
Figure 5, and are connected by threads passed over said spears and falling within the
notches, 2, of the edges.
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 1
claim is:
1. In a garment fastening device the fly catch consisting of a main hooked
plate, A, having a central oviform opening, a³, marginal perforations and edge
notches, in combination with folded staple, B, having four outwardly extending spears
provided with edge notches, adapted to be inserted through the fabric of a garment
and folded in opposite directions upon said fabric, as and for the purpose intended,
substantially as described.
2. In a garment fastening device the staple, B, consisting of two base strips,
integrally connected and adapted to be folded over to form a laminated member, each
strip having outwardly extending pointed spears provided with notched edges, as and
for the purpose intended, substantially as described.
