COMPLETE SPECIFICATION.
Improvements in Buttons or Studs
I, GEORGE WASHINGTON LEE, of Binghamton, in the County of Broome, State
of New York, United States of America, Manufacturer, 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:-
-
This invention relates to an improvement in separable buttons or studs of that
class in which provision is made for clamping the material to which the button
or stud is attached firmly between the base and shank of the said button or
stud.
The objects of my invention are to provide a button or stud comprising two
separable members in which the base member is provided with means for retaining
it against rotary movement when the shank section is screwed thereon and in
which the head member is provided with means for preventing the unintentional
unscrewing thereof without the use of separate parts or springs.
A further object is to provide a separable button or stud in which the clamping
washer is loosely retained at all times upon the shank of the head portion so as
to obviate the danger of losing the said washer when the head and base are
separated.
A practical embodiment of my invention is represented in the accompanying
drawings, in which
Figure 1 represents a side view of my improved button or stud in its operative
position with a band of suitable material clamped therein.
Figure 2 is a vertical central section through the same.
Figure 3 is a vertical central section through the button or stud showing the
head and base members separated.
Figure 4 is a vertical central section through a modified form of button or stud
in which the upwardly extended portion of the socket piece is cut off to permit
a stud or button being formed with a very small neck or shank.
Figures 5, 6, 7, 8 and 9, represent detail vertical sectional views of the several
parts of the button or stud.
Figure 10 is a top plan view of the socket piece.
Figure 11 is a bottom plan view of the same, and
Figure 12 is a top plan view of the clamping washer.
The separable button or stud comprises two separable members, viz.; a head a
and a base b. The head a has a shank c within which is located a socket piece d.
This socket piece, in the form shown in Figure 3, is provided with a portion e
extending upwardly within the neck of the shank while in Figure 4 the
socket piece is shown without the said upwardly extending portion e so that
the shank c of the head may be made of small diameter.
The socket piece d is held in position by crimping the bottom edge of the
shank c of the head around its rim so that the socket piece and the head are
substantially integral with each other. The socket piece is further provided
with a downwardly extended cylindrical portion f upon which is loosely retained

page_text: a dish shaped clamping washer g. This washer is held against removal from the
said socket piece by spreading the bottom edge of the extension f, as shown.
The base comprises a base plate h having an upwardly extended screw
threaded stem i adapted to enter the socket piece d in the head, whereby, as the
head is screwed home, the material is clamped between the said base plate h and
the washer g.
For preventing the base plate from turning, as the head is screwed home, I
provide the base plate with one or more projections j uprising from its upper face
in position to enter the material upon which the button or stud is being secured.
The base plate h may be provided with a cap k as is usual, which cap is preferably
applied by crimping its edges over the rim of the said base plate h.
For preventing the unintentional unscrewing of the head after the material
has been clamped between the base plate and washer, the washer is provided
with an annular series of teeth or corrugations and the socket piece d is provided
with one or more projections m which are adapted to engage the said teeth,
which projections are located adjacent to each other as shown.
The teeth extend in a direction to permit the projections to travel along the
same, as the head is being screwed home, the spring in the metallic body of
the washer being sufficient to permit the washer to yield slightly as the projections
travel over the teeth. The teeth stop the unintentional reverse movement of
the projections m and the head is thereby prevented from unscrewing unin-
tentionally.
By this means I am enabled to do away entirely with the use of separate springs
and other parts for locking the head and at the same time permit the washer 7
to be loosely retained upon the downward extension f of the socket piece.
The button or stud as thus constructed may be very quickly clamped to the
material in the desired position and it will retain its position until intentionally
removed therefrom.
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 18:―
A separable button or stud comprising a base having a screw threaded stemn
uprising therefrom, a head having a downwardly extended shank, a screw threaded
socket piece secured within the shank in position to receive the said stem, a washer
loosely retained by the said socket piece, the said washer being provided with an
annular series of teeth and the said socket piece being provided with one or more
projections in position to engage the teeth and travel over the same as the head
is screwed home, substantially as set forth.
