JOHN IMRAY of N° 28 Southampton Buildings Chancery Lane in the County of
Middlesex "IMPROVEMENTS IN BUTTON FASTENINGS." [Communicated to him
from abroad by Anna M.Kevit of Chicago, Illinois, in the United States of
America]
This invention relates to button fastenings of the separable kind, that is to say
of the kind in which the body of the button has a screwed shank which is passed
through the fabric from one side and secured by a nut on the other side:
According to this invention, the shank which forms part of, or is fixed by rivetting
soldering or otherwise to the body of the button has on it two collars, the one
bearing close against the under face of the button body and the other bearing
against the face of the fabric to which the button is fixed, the space between the
collars being wide enough to receive the fabric in which the button hole is formed,
The screwed end of the shank is pointed so as easily to penetrate the fabric and
the nut which is screwed on the under side of the fabric is of disc form thickened
considerably in its middle so as to present a central boss giving considerable depth
of screw thread. Instead of forming the two collars on the shank as above
described, a sleeve with a concave groove in its middle may be slid on the shank,
one face of the sleeve bearing against the body of the button and the other face
against the fabric through which the shank is passed. And this face may be
recessed to receive the boss of the nut which is made with a tapered end to pass
through the fabric from the other side and to enter the recess of the sleeve. When
the body of the button is made of wood or equivalent material covered with fabric,
the shank is made with one end to screw into this body, up to a collar provided
on the shank, so that it is firmly held in the body and does not readily become
unscrewed when the nut is unscrewed to detach the button from the fabric.

JOHN IMRAY of N° 28 Southampton Buildings, Chancery Lane in the County
of Middlesex *IMPROVEMENTS IN BUTTON FASTENINGS A communication to
me from abroad by Anna M°Kevit of Chicago, Illinois in the United States of
America
This Invention relates to that class of button fastening which can readily be
attached to or detached from the fabric by screwing or unscrewing & nut fitting a
screwed stem or shank projecting from the body of the button.
The object of this invention is to provide a fastening adapted to buttons of any
form and material; to lessen the cost of production; to produce a strong and
durable separable button with the least number of detachable parts.
I will describe the construction which I employ referring to the accompanying
drawings. Fig. 1 is a side view of one form of the fastening in position in the
_fabric and button hole, which are shown in section. Fig. 2 shews the body of the
button and the nut or under-button separate. Fig. 3 shews the same fastening
for a button of different form. Figs. 4 and 5 shew modified forms of the shank
and nut. Fig. 6 illustrates another form of the fastening of which Fig. 7 is a
section, Fig. 8 being a section of the nut shewn separately and Fig. 9 being a
section of the button and shank and Fig. 10 a section of the collar. Fig. 11
illustrates another form of the fastening of which Fig. 12 is a section, Fig. 13
shewing the shank, collar and nut detached from the button.
-
A is the body of the button, which may be of any suitable form or material.
To its under side is firmly attached a shank B, which may have a collar a bearing
against the button as shewn, or may be made without this collar. On the
shank B is a collar or flange b, and beyond this collar the shank is screw threaded
and tapered to a point.
C is the nut or under button of a disc form, with a central boss & through which
is a hole, screwed to fit the shank B. The face of the boss d may be plain as in
Figs. 2 and 3 or it may be hollowed as shewn in Fig. 4, or rounded as in Fig. 5,
the under face of the collar b being rounded or hollowed to correspond. That
portion of the shank between the button body and the collar b on which the
button hole engages, is round and smooth. The shank B is pointed to allow of
its being readily pushed through the fabric, wherein it is secured by the nut C
which clamps the fabric between it and the collar b.
Referring to Figs. 6, 7, 8, 9 and 10 A is the body of a button having the
shank B¹ secured to it by rivetting, soldering or otherwise, and extending from it
with a screwed and pointed end. C₁ is a sleeve which is passed on to the shank
and may be fixed thereon. One side of this sleeve fits against the underside of the
button A. In the other side of the sleeve is formed a recess of which receives the
boss & projecting from the nut D, this boss being bevilled off as shown in Fig. 8
so that it can be easily passed through the fabric.
The sleeve C. is preferably made with a rounded groove to receive the button
hole. All the projecting part of the shank might be screwed and the sleeve C'
could be screwed upon it.
The fastenings shewn in Figs. 11, 12 and 13 are especially applicable to buttons
having a body A of wood or other material covered with fabric A. F is the shank
screwed at both ends with a flange or collar f¹ near its middle; a smaller flange a¹
may also be made on this shank as shewn in Fig. 13. D¹ is the nut. Both ends of

page_text: the screw are pointed, the one end to enter with facility the body A, and the outer
end to penetrate the fabric G. The part of the shank that enters the body of the
button should be firmly screwed into the collar, so that it is not readily loosened
out when the nut D is unscrewed for the purpose of removing the button in order
to apply it to another garment.
The various constructions described above have for their object to constitute &
button fastening in which a considerable depth of screw is provided without an
inconvenient thickening of that part of the nut or under button which bears
against the fabric; thus great security and durability are obtained, and the
fastening is capable of being used with fabrics varying considerably in thickness.
Having thus described the nature of the said invention and in what manner the
same is to be performed as communicated to me by my foreign correspondent,
I claim :-
First. Constructing button fastenings of a button body having a shank with a
collar at an intermediate point of its length, the end portion of the shank beyond
the collar being screw threaded and screwing into a nut or under button,
substantially as herein described with reference to Figs. 1, 2 and 3 of the
drawings.
Second. In button fastenings constructed as set forth in the preceding claim,
making the meeting surfaces of the collar and nut or under button respectively
convex and concave substantially as herein described with reference to Figs. 4 and 5
of the drawings.
Third. Constructing button fastenings of a button body having a screwed shank
screwing into a nut or under button, and a sleeve fitted on the shank, the said
sleeve being provided with a recess into which a tubular boss of the nut passes,
substantially as herein described, with reference to Figs. 6 to 10 of the drawings.
Fourth. Constructing button fastenings of a button body into which is screwed
one end of a shank having a collar at or about the middle of its length, and
screwing with its other end into a nut or under button, substantially as herein
described with reference to Figs. 11, 12 and 13 of the drawings.
In Witness whereof, I the said John Imray have hereunto set my hand and
seal this First day of August in the year of our Lord One thousand eight hundred
and eighty three.
