Warwick Engineer, 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 :-
The Cap is fastened on curved end of Safety Pin wire in a circular grove A made
two thirds of the way round Cap, the remainder third part of Cap formed into a Cam
Lock, to accept Safety Pin point E which passes over Cam B. under Spring D. into
Chamber C. Spring D closing part of the way to Cam B. and makes Safety Pin
point E securely locked in Chamber C. the Cam B. Chamber C. Spring D. to be used
either sides of Cap.
Fig. 1. Cap. Improvements in Safety Pins Cap is formed out of a blank cut in
a suitable shape to suit the following details of my invention :-Two thirds of the
way round cap is a circular grove A. The remainder third part chamber () is formed
into a cam lock at the same time that the circular grove A and chamber Care formed,
cam B is formed and raised up on blank used for cap, which may be formed of any
suitable material or quality with surface to form cam B between grove A and
chamber C. At the same time spring D is formed with a flap projecting over cam B
and forms an aperture to be used either sides of cap to suit the fulcrum of safety pin
point E passing in and out of chamber C. The curved end of safety pin wire is placed
in the circular grove A two thirds of the way round cap. Then closing circular
grove A on curved end of Safety pin wire the cap is securely fastened on curved end
of safety pin wire with a firm grip.
Fig. 2. shows end view of cap. Where the fulcrum of Safety pin point E is placed
on cam B at the entrance of aperture ready to raise spring D and pass same into
chamber C.
Fig. 3 shows end view of cap. Where the fulcrum of Safety pin point E is locked
in chamber C. and the spring D closed to its resting position over cam B. The
safety pin is then finished with perfect cam lock in one third of cap.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
No. 1. Improvements in safety pins. One third the cap is a perfect cam lock with
an aperture the width of which is made to suit safety pin point E the aperture varying
in different widths to suit any guage of wire or material used for safety pins.

page_text: No. 2. To lock safety pin. The fulcrum of point E is placed on cam B with thumb
and finger at the same time pressing fulcrum of safety pin point E. The fulcrum
raises spring D the safety pin point E then passes through aperture is locked in
chainber C.
No. 3. To unlock safety pin. Point E is raised with thumb and finger out of
chamber C on cam B at the same time the fulcruin of safety pin point E raises
spring D allowing safety pin point E to pass back out of aporture the safety pin is
then open.
