I, JOHN ROBERTS of 22 High Street, Cleator Moor in the County of Cumberland,
Inventor do hereby declare the nature of my said invention for IMPROVEMENTS
IN HANKS. OR SAFETY LOCKING ATTACHING HOOKS, APPLICABLE FOR HOISTING. OR
DRAWING HEAVY ARTICLES to be as follows:-
This invention has for its object a hook or hank that when hooked shall
automatically be converted from a hook into a closed: ring. The hook is. formed
of a variety of shapes to suit circumstances, but all shapes have this in common,
that the hook proper has a circular contour opposite the opening, and a second
vacant space at the bottom of the circular space, and the circular space is filled up
with one or more wheels having each a hiatus, vacancy or gap at one point, and
counterweighted so that the gap shall naturally stand uppermost or to the upper
part of the back.
The mode of action is as follows:
The wheel or wheels (hereafter the singular only will be mentioned) is turned
by hand till its vacancy comes opposite the opening in the hook. The article to
be hooked is then passed into the vacancy in the wheel, and the wheel revolved
by the weight of the article or otherwise, till the article drops into the second
vacant space below the wheel! The wheel freed is then turned by its counter-
weight till the vacancy is quite clear of the opening. To extract the article the
wheel is again turned till the vacancy is at the bottom, the article is lifted into its
vacancy, the wheel again turned till the vacancy in it is opposite the hook opening
when the article can be at once extracted. I may sometimes weight the wheel so
that its vacancy shall always naturally stop opposite the opening in the hook.
The part of the wheel not used by the article, I prefer to cover on each side by a
shield of metal either fastened to the wheel and overlapping the hook or preferably
fastened to the hook, covering a large part of the wheel.

I, JOHN ROBERTS of 22, High Street, Cleator Moor in the County of Cumberland,
Inventor, 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 has for its object a hook or hank that when hooked shall
automatically be converted from a hook into a closed ring.
It is best described by aid of the accompanying drawings in which-
Figures 1 and 2 are side elevations of hook in two slightly different positions.
Figure 3 front view.
The hook is formed of a variety of shapes to suit circumstances, but all shapes 1
have this in common, that the hook proper A has a circular contour at B, and
circular space opposite the opening, and a second vacant space C at the bottom of
the main circular space, and the main circular space is filled up with one or more
wheels D having each a hiatus, vacancy or gap E at one point, and counter-
weighted at F or fitted with a spring, but I prefer the former so that the gap shall
'naturally stand uppermost or to the upper part of the back.
The mode of action is as follows-
The wheel (or wheels) D (hereafter the singular only will be mentioned) is
turned by hand till its vacancy E comes opposite the opening in the hook. The
article G to be hooked is then passed into the vacancy in the wheel, and the wheel
revolved by the weight. of the article or otherwise, till the article drops into the
second vacant space C below the wheel as shown. The wheel freed is then turned
by its counterweight till the vacancy is quite clear of the opening O. To extract
the article the wheel is again turned till the vacancy E is at the bottom, the
.article is lifted into its vacancy, the wheel again turned till the vacancy in it is
opposite the hook opening when the article can be at once extracted-I may
sometimes weight the wheel so that its vacancy shall always naturally stop
opposite the opening in the hook. The part of the wheel not used by the article,
I prefer to cover on each side by a shield H of metal, either fastened to the wheel
and overlapping the hook, or preferably fastened to the hook, covering a large
part of the wheel, and carrying the journal I of wheel D.
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 -
1st. A hank or safety locking device applicable for hoisting or drawing heavy
articles in which a revolving locking piece having a suitable recess is placed in the

page_text: mouth of the hook, and is turned by the weight of the article suspended till it
deposits the article in a recess when it is returned to the lock position by a
counterweight or its equivalent, substantially as described.
2nd. The combination of hook A having recess C shields H and recessed,
counterweighted wheel D, substantially as described.
