AN IMPROVEMENT OR IMPROVEMENTS IN HAND CUFFS to be as follows
Year: 1885

page_text: I ALFRED DUCKWORTH MELSON of the firm of Hiatt and Company of N° 26
Masshouse Lane Birmingham in the County of Warwick Manufacturers do hereby
declare the nature of the said Invention for "AN IMPROVEMENT OR IMPROVEMENTS
IN HAND CUFFS to be as follows:—
"J
The object of my invention is to make the handcuff capable of adjustment to the
size of the wrist on which it is to be worn.
This object I effect in a simple and efficient manner by constructing and
arranging the parts as hereinafter described.
A hand cuff as ordinarily constructed consists of an open loop to one end of
which a case containing a spring sliding bolt is jointed the free end of the loop
passing into a hole in the top of the bolt case and being fastened by the end
of the bolt snapping into a slot in the said free end of the loop.
In constructing a hand cuff according to my invention I prolong or lengthen the
free end of the loop so that it can pass some distance through the bolt case and on
the underside of the said prolonged free end of the loop I make a rack having
inclined teeth with which teeth the top of the spring sliding bolt in the case can
be engaged. When the end of the spring bolt has been engaged with the first
tooth that is the tooth at the extreme end of the loop the hand cuff has its full
size. In order to diminish the size of the hand cuff the bolt case is pressed
inwards. It is thereby made to turn upon its joint and cause the spring boit
carried by it to slide over the inclined teeth of the rack and abut against the
shoulder or vertical side of that tooth to which it has been brought. In this way
the size of the loop of the hand cuff can be adjusted so as accurately to fit the wrist
the return motion of the bolt and consequently the unfastening of the hand cuff
being prevented by the vertical side of the tooth against which the bolt abuts.
By means of the key the end of the bolt can be withdrawn from the rack and
the hand cuff unfastened.
Instead of a rack as described the end of the loop may be provided with a series
of holes in any one of which the end of the spring bolt may snap to fasten the
hand cuff.

I ALFRED DUCKWORTH MELSON of the firm of Hiatt and Company of No 26
Masshouse Lane Birmingham in the county of Warwick, Manufacturers do hereby
declare the nature of the said invention for AN IMPROVEMENT OR IMPROVEMENTS
IN HANDCUFFS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of my invention is to make the handcuff capable of adjustment to the
size of the wrist on which it is to be worn.
i This object I effect in a simple and efficient manner by constructing. and
arranging the parts as hereinafter described.
A handcuff as ordinarily constructed consists of an open loop to one end of
which a case containing a spring sliding bolt is jointed the free end of the loop
passing into a hole in the top of the bolt case and being fastened by the end of the
holt snapping into a slot in the said free end of the loop.
In constructing a handcuff according to my invention I prolong or lengthen the
free end of the loop A so that it can pass some distance through the bolt case B
and on the underside of the said prolonged free end of the loop I make a rack C
having inclined teeth with which teeth the top of the spring sliding bolt in the
case D can be engaged. When the end of the spring bolt D has been engaged with
the first tooth that is the tooth at the extreme end of the loop C the handcuff has
its full size. In order to diminish the size of the handcuff the bolt case B is
pressed inwards. It is thereby made to turn upon its joint E and cause the spring
bolt D carried by it to slide over the inclined teeth of the rack C and abut against
the shoulder or vertical side of that tooth to which it has been brought. In this
way the size of the loop of the handcuff can be adjusted so as accurately to fit the
wrist, the return motion of the bolt and consequently the unfastening of the
handcuff being prevented by the vertical side of the tooth against which the bolt
abuts.
By means of the key F the end of the bolt can be withdrawn from the rack and
the handcuff unfastened.
Instead of a rack as described the end of the loop may be provided with a series
of holes in any one of which the end of the spring bolt may snap to fasten the
handcuff.
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
That my handcuff possesses the advantage that it will fit any wrist.
