1, GEORGE KREMENTZ of 347 Washington Street, Newark, in the County of Essex
and State of New Jersey, United States of America, Manufacturer of Jewelry 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 certain new and useful improvements in studs or collar
buttons; and the object of the invention is to provide a new and improved collar
button which is simple in construction, strong, and durable, and which requires no
soldering of parts.
In the accompanying drawings, figure 1 is a side view of the improved collar
button. Figures 2, 3, and 4, are cross sectional views of the same during the
different stages of the manufacturing process. Figure 5 is a cross-sectional view of
the completed collar button. Figure 6 is a cross-sectional view of a modified con-
struction of the same. Figure 7 is a cross sectional view of a button provided with a
back or bottom-plate. Figure 8 is a cross-sectional view. of a modified construction
of the same. Figures 9, 10, and 11 are cross-sectional views of the button shewing
different shapes of the head and shank. Similar letters of reference indicate corre-
sponding parts in all the figures.
At
A circular metal plate is pressed into the shape shewn in figure 2, by means of
suitable implements and then the sides are pressed inwards by means of suitable dies,
to form a hollow stem or shank B and a hollow head A at the end of the same.
the open end, the stem or shank B is flared so as to form the base plate which is
turned toward the head at the outer edges, as shewn, and the edge is turned over, as
shewn, to form a bead. The head is pressed down so as to have the shape shewn in
figure 5, or it may have any other desired shape, for example, flattened and bevelled
as shewn in figure 9, or rounded or made approximately elliptical at the top as shewn
in figure 10, or it may be made spherical as shewn in figure 11.
If desired, the top and bottom layers of the hollow head C may be pressed together
to be in contact, as shewn in figure 6, so as to give the machine made button the
appearance of a hand made button. The lower ends of the stems or shanks of the

page_text: buttons shewn in figures 1 to 6 are open, and fibrous particles from the clothing etc.,
are apt to pass into the buttons, which is objectionable, and also in case the buttons
are made of rolled gold, that is sheet metal having gold on one side and base metal on
the other, the base metal would shew on the inside of the bell-shaped open end of the
shank. To prevent this, a back plate E of metal is placed on the open end of the
shank that is on the base plate, and the edges of said back plate E are drawn over
the edges of the base-plate, as shewn in figures 7 and 8. As shewn in figure 8, the
centre of the plate E can be forced inward so as to give the button approximately
the appearance of a button not provided with said plate E.
The buttons can be made of any size and may have any desired thickness of
material.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, 1 declare that what I claim is ;—
1. A collar button or stud, having a hollow head and stem, said head, stem, and the
base-plate or back of the button being made of a single continuous piece of sheet
metal, and a back covering plate being secured over the base plate or back of the
stud, substantially as set forth.
2. A collar button or stud, having a hollow stem, a hollow head, and a base plate;
all made integral, of a single and continuous piece of sheet metal and without any
seams or joints, substantially as set forth.
3. A collar button or stud, having a hollow stem formed on a base plate or back,
and a hollow head on the stem; the said hollow head, stem, and base plate, being
made of a single continuous piece of sheet metal and the top and bottom layers of said
head being pressed together to be in contact, substantially as set forth.
Dated this 8th day of November 1887.
