Improvements in Safety Pins and Safety Suspending Pins.
I. THOMAS WILLIAM BROUGHTON, of 9, Thimble Mill Lane, in the City of
Birmingham, Pin Machinist, 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 the manner in which I construct and arrange safety pins
and safety suspending pins for use upon articles of clothing, and for suspending
dresses, curtains or other fabric, and for like purposes, whereby I am enabled to
produce a strong pin and to obtain a safe attachment in a very simple and
convenient manner.
In carrying my invention into effect when constructing a safety pin for use with
a hook for suspending curtains and for similar purposes, I form the hook and pin as
shown at Figure 1 and Figure 2 upon the accompanying sheet of explanatory
drawings in which A is the safety pin with a central bow or loop a to which the
hook B is attached. Upon the same loop or bow a I place a strengthening clasp
or bar support c which I cause to pass under the pin portion A' and thus to receive
the pull or weight of the material which may be upon the pin A¹ and at the same
time to form a bar for preventing the material from slipping or sliding all towards
one end or edge of the pin. By this arrangement of bar support I produce a much
stronger pin than is at present possible with the same diameter of wire, and I cause
an even distribution of the weight of the material.upon the pin, seeing that the bar
divides the length of the pin into two spaces each of which receives a portion of the
material to be carried.
I sometimes attach a spring hook as at Figure 3 and Figure 4, or a ring as at
Figures 5 and 6 to suit any particular requirement.
Similarly I sometimes attach a button G to the suspending hook F as shown in
Figures 7, 8, and 10 for use upon trousers and for like purposes.
I make the central bar or strengthening clasp c either out of a metal strip as in
Figure 1 to Figure 7 or in plain single or double wire as at c¹ Figure 9 and
Figure 10.
When constructing a safety pin having the pin securely held or locked by the
bar c², I provide a projecting loop or end c and c as shown at Figure 12 and
Figure 13 which forms a recess into which the pin A¹ may fit, and from which it
cannot be removed except by the withdrawal or release of the bar c².
I lock the pin H¹ within the end loop H' as shown at Figures 14, 15, 16 and 17,
the wire H2 being bent down to form a spring bar to keep the point of the pin
within the frame at H'. I make the spring bar or spring end of the wire either as
shown at H2 Figure 15, or slightly open as shown at H³ Figure 16, and I employ
this method of securing and locking the pins either when employed with
books, rings and other suspenders or when employed as plain pins as shown at
Figure 17.
For greater convenience in entering the pin joint J¹ within the end loop of the
frame, I make the end with a double opening J2, J³ as shown at Figures 18, 19 and 20;
by this system of construction the pin J' can be introduced into either side J², Ja
and thus can be readily manipulated. I prefer to form this double entry pin with
two loops K', K2 Figure 21 when arranging this form of pin for suspending any
material, the loops being formed in the same manner as set forth in the Specification
No. 12,267 of 1889 for which a Patent has been granted to me.
I do not limit the application of my invention to any particular form of
suspending hook, button or other device which it may be desirable to attach my
improved safety pins, but I modify the form and strength of the pin to suit any

page_text: ordinary attachment which may be necessary for any particular or peculiar
requirement.
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 is :-
(1) The construction and arrangement of safety pins having a central supporting
bar or loop for passing under the pin wire, substantially as and for the purposes
herein before described and as illustrated in the accompanying drawings.
(2) The construction and arrangement of safety pin suspenders having the pin
wire supported by means of a bar or clasp substantially as and for the purposes
herein before described and as illustrated in the accompanying drawings.
(3) The construction of safety pins and suspenders having a strengthening bar
or clasp with a locking recess such as at c³, c', Figure 12 and Figure 13 of the
accompanying drawings.
(4) The construction of safety pins and suspenders having lock spring bars to
secure the points within the ends of the frames substantially as herein described
and as illustrated at Figures 14, 15, 16 and 17 of the accompanying drawings.
(5) The construction of safety pins and suspenders having double entry ends
for the pin points substantially as hereinbefore described and as illustrated at
Figures 18, 19 and 20 of the accompanying drawings.
Dated this 4th day of February 1892.
