COMPLETE SPECIFICATION filed by the said Henry Harris Lake at the
Office of the Commissioners of Patents on the 18th December 1883.
HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings London, "IMPROVEMENTS IN AND RELATING TO SAFETY
PINS AND SIMILAR ARTICLES." Communicated to me from abroad by Joel Jenkins
and George P. Farmer both of Mont Clair, New Jersey, United States of
America.
This invention relates to safety or spring pins, and has for its object to improve
the said pins, and also the general application of safety pins for the purpose of
attaching breast pins, chatelaines, brooches and the like to garments, by combining
safety pins with a suitable metal backing for such purposes in the manner herein-
after described. Safety pins have heretofore been used simply as such, and without
any other attachment, so that their application has been somewhat limited to the
special purposes for which such pins were adapted.
The said invention consists partly in providing a safety pin fixed to a metal
back in the manner hereinafter described; it also partly consists in providing a
pin with a looped spring and convoluted shield constructed and combined in the
manner herein-after shown and described.
In the accompanying drawing
Figure 1 is a perspective view of a safety pin with a looped spring attached to a
brooch
.
Figure 2 is a perspective view of a plate with a recessed seat

seat with a pin inserted therein.
Figure 5 is a perspective view of the underside of an ornament to be attached.
Figure 6 is a perspective view showing the recessed seat with the shield
attached to the plate and illustrating one method of securing the plate to the
brooch.
Figure 7 is a perspective view showing the looped spring and the convoluted
shield.
Figure 8 is a side view of a pin having a common coiled spring and shield.
Figure 9 is a perspective view of the underside of the plate showing the sectional
recessed seats, and the hook for the pin.
Similar letters of reference indicate corresponding parts in the several figures.
In constructing the improved safety pins, either in the ordinary forms of safety
pins now made, or in the particular form hereinafter described, I strike up or
stamp upon a plate A of any desired size and material, one or more recessed seats a
having openings b and c at each end of the seat. The depth of the seat or seats
should correspond, to some extent with the size of the wire of which the pins are
made and the length of the seat, or if there are more than one, the combined length
of the several seats, should equal the length of one side or member d of the pin.
The seat having been formed as described, the member d of the pin, before its
shield B has been fixed to it, is inserted through the opening b at one end of the
recessed seat a until the end of the inserted member or side of the pin projects
sufficiently through the seat a to permit the fixing of the shield B to it; then by
solder, or any other convenient means, the inserted member of the pin is secured
to the plate A. The plate can now be attached to any brooch, breast pin, chate-
laine or any other ornamental or useful piece of jewellery that requires a pin
attachment.
That the operation of the pin may be more effective than is the operation of
similar pins, having the ordinary and common coiled spring at one end, I construct
the pin with a looped spring C, through the loop of which the rear part of the
sharpened member e passes; the result being an increased leverage of the sharp
member of the pin, the loop referred to acting as a fulcrum for the leverage of this
member e.
The manner of constructing the loop or lever of this spring may vary as desired.
To further construct the safety pin in a strong and serviceable manner, so that its
shield cannot become detached from the wire of which the spring is formed, the
said shield may be made of folds or convolutions on the end of the member d of
the pin and these convolutions folded over as shown in Figure 7. By constructing
the safety pins in this manner, it will be seen that the spring and its shield are
made entirely of one piece of wire and are therefore very strong. When a pin of
such construction is secured to a plate or back A, in the manner herein before
stated, a firm and useful combination of the pin, back, and brooch, or other
ornamental jewellery is effected, and the annoyance caused by the breaking of the
usual hook is avoided.
Instead of making the shield of convoluted wire and with a looped spring
having the lever action, the common safety pin with coiled spring f and shield g
may be employed in connection with the back A.
Having thus fully described the said invention as communicated to me by my
foreign Correspondents, and the manner of performing the same, I wish it
understood that I do not confine myself to the application of any particular kind
of safety pin but I claim
First. A safety or spring pin in combination with a back A and a brooch, as,
and for the purpose, described.
Second. In combination, a safety pin having a back A, one or more recessed
seats a, and a brooch or other ornament, as set forth.
Third. In combination, a safety pin with a looped spring and a convoluted
shield, in combination with a back A, as, and for the purpose, described.

page_text: Fourth. A safety pin having its spring, its shield, and its two members made
from one piece of wire in the manner hereinbefore described.
Fifth. A safety pin having a convoluted and bent shield and a looped fulcrum
spring, the said shield, the spring, and the members of the pin being made of one
piece of wire, as, and for the purpose, described.
In witness whereof I the said Henry Harris Lake have hereunto set my hand
and seal this Eighteenth day of December in the year of Our Lord One thousand
eight hundred and eighty three.
HENRY, H. LAKE (L.S.)
