Improvements in Movable Collar Studs.
We, WILLIAM ERNEST PATTERSEN, of 189, Warstone Lane, Jeweller; and
HOMAS MORTON, of Saint George's Place, Manufacturer, both in the City of
Birmingham, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in collar studs, having movable
shanks, and consists in constructing and combining the shank having a turned
down lever top, to the base in such a manner that it shall be capable of a
certain amount of movement out of the vertical to such base under pressure,
but shall automatically return to the vertical.
In carrying out this invention, the top of the shank is made with a turned
down or what is called a lever button, having a movement at right angles to the
seesaw movement of the shank hereinafter explained. The lower end of the
shank is made with a flat surface, and also near to such end are pivots formed one
on either side. A plate is now made having a central hole through which the
shank is passed, and upon each side of this hole, the metal is indented so as to
form the bearings to receive the pivots upon the shank. At the sides of these
bearings the metal is also raised, so that when the pivots are placed in the
bearings, such raised parts are closed down somewhat, sufficient to retain the
pivots in said bearings. In the base of the stud is now fixed a spring against
which the flat end of the shank shall impinge; when the shank and its bearing
plate is now secured to the said base plate.
This may be done by connecting the two said plates direct to each other, or
preferably we employ a further cover plate, over the bearing plate, by which
such securing to the back plate may be effected. If desired the spring may be
secured to the bearing plate.
Its action is therefore as follows:-The shank is capable of a side seesaw kind
of movement, in which the spring is deflected by each movement, and in right-
ing itself the spring brings the shank back into its upright position, while the
top button has a lever turn down movement in a plane at right angles to that
of the shank.

We, WILLIAM ERNEST PATTERSEN, of 189, Warstone Lane, Jeweller, and
THOMAS MORTON, of Saint George's Place, Manufacturer, both in the City of
Birmingham, do hereby declare the nature of this invention and in what manner

page_text: the same is to be performed, to be particularly described and ascertained in
and by the following statement:
This invention relates to improvements in collar. studs, having movable
shanks, and consists in constructing and combining the shank having a turned
down lever top, to the base in such a manner that it shall be capable of a
certain amount of movement out of the vertical to such base under pressure,
but shall automatically return to the vertical.
In order to more clearly explain this our invention we have appended here-
unto an illustrative drawing upon which are figures and numbers of reference,
similar numbers referring throughout to the same thing or part.
Fig. 1, is a front elevation, and Fig. 2, a side elevation of a stud constructed
according to this my invention.
Fig. 3, shows a front and side view of the shank.
Fig. 4, is a plan view, and Fig. 5, a sectional view of the bearing plate on
line A-B.
Fig. 6, is a plan view of the spring plate.
Fig. 7, is a part sectional view showing the parts assembled.
Fig. 8, is a plan view, and Fig. 9, a sectional view of the same on line C-D.
Fig. 10, is a plan view, and Fig. 11, a sectional view on line E-F of a back
plate to support pressure upon the spring plate.
Fig. 12, comprises plan and elevation views in detail of binding rim for con-
necting and holding the modified parts together.
Fig. 13, is a sectional view in elevation, and Fig. 14, a plan view of the
modified arrangement.
Fig. 15, is a part sectional view of the modification showing the parts
assembled.
Referring to Figs. 1 to 7 inclusive, the shank 18, is made with a turned
down or what is called a lever button 19, having a movement at right angles
to the seesaw movement of the shank, as indicated by dotted lines in Fig. 2.
The lower end of the shank is made with a flat surface, and also near to such
end, pivots 20, are formed, one on either side, see Fig. 3. A plate 21, is now
made having a central hole 21ª, through which the shank is passed, and upon
each side of this hole, the metal is indented so as to form the bearings to receive
At 22, in the sides of these
the pivots 20, upon the shank, see Figs. 4 and 5.
bearings the metal is also raised, so that when the pivots are placed in the bear-
ings, such raised parts are closed down somewhat, sufficient to retain the pivots
in said bearings. In the base of the stud is now fixed a spring 23, against
which the flat end of the shank shall impinge, as seen in Fig. 7. The whole is
now secured together as shown in Figs. 1, 2 and 7, by means of the cover
plate 24, over the bearing plate, and embracing the edge of the back 25.
Referring to Figs. 8 to 15 inclusive, in some cases the bearings and the
spring may be formed in one and the same plate as seen at 26, see Figs. 9, 10,
14, and 15, in which the central hole 21ª, is made through which the shank is
passed. The end of the shank may rest upon the interior of the back, at 27,
but preferably we provide the plate 28, which is secured to the spring plate by
means of the frilled collar 29 (Fig. 12) as shown in Figs. 13, 14 and 15. To
the parts thus assembled may now be added the cover plate 24, and the back 25,
and completed as shown in Fig. 15.
Its action is therefore as follows:-The shank is capable of a side seesaw kind
of movement, as seen in dotted lines in Figs. 2 and 14, in which the spring
is deflected by each movement, and in righting itself the spring brings the shank
back into its upright position, while the top button has a lever turn down
movement in a plane at right angles to that of the shank,
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In a stud. the combination of a rigid shank having sideway movement

page_text: and spring device for returning shank to its upright position, substantiany
set forth and shown upon the drawings.
2. In a stud having a side way moving shank with pivots 20, the combination
with such shank of the bearing plate 21, having pivot bearings, and a spring 23,
set forth and shown in
substantially as
all constructed and operating
Figs. 1 to 7.
3. In a stud having a sideway moving shank having pivots 20, the com-
bination with such shank of a combined bearing and spring plate 26, with or
without back pressure plate 28, all constructed and operating substantially as
set forth and shown in Figs. 8 to 15.
