Rope Clamp.
I, WILLIAM HENRY BOMм, of Westwood, County of Bergen, and State of New
Jersey, U.S.A., Farmer, do hereby declare the nature of this invention to be as
follows:-
A link is provided with a hook extension; a plate is hinged to said link, and
is of greater length than the same whereby it overlaps a portion of the said
hook extension and coacts with the same to clamp the rope; a ring, or other
device, is secured to the under side of said plate and is fulcrumed on the housings
forming the hinged connection thereof whereby additional means are provided
to hold the plate against the said hook extension.

I, WILLIAM HENRY BOMM, of Westwood, County of Bergen, and State of New
Jersey, U.S.A., Farmer, 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 rope clamps, and the object thereof is to provide a
cheap and effective clamp, with means for the ready insertion of the rope therein.
In the accompanying drawing:
Figure 1 is a bottom plan view of my improved rope clamp; and,
Figure 2 is a central, longitudinal section thereof on the line 21-21 of
Figure 1.
In the drawing, 5 is the link, having straight end 6, and one of the sides is
turned inwardly at 7, and meets the opposite side 8, at 9; and the side 8 is
provided with a hook-shaped extension 10. 11 is the clamping plate, having two
housings 12, in which the end 6, of the link 5 is mounted, thereby forming a
hinged connection. Centrally of said plate, adjacent to the end thereof, is formed
a third housing 13, in which is mounted a ring 14, which is so proportioned that
the sides thereof will bear upon the housings 12 when in use, thereby using the
said housings as a fulcrum, and acting as a lever to draw the free end of said plate
against the hook-shaped extension of said link.
The free end of said plate is concaved as shown at 15, but this feature is
rn

page_text: not essential, and the plate is so proportioned in length that it will overlap a
portion of the end of the hook, as shown at 16.
In operation, the plate is swung on its hinged connection until the rope can be
easily inserted within the hook, then the plate is forced down upon the rope ;
and as the ring 14 acts as a lever, the more stress placed upon the rope, the
more firmly will the plate be forced upon it.
I may also use a spring 17, in cases where it is desirable to use the clamp
upon ropes where no stress, or intermittent stress is used upon the rope; in
which case I provide two housings 18, in which the yoke-shaped spring 17 is
mounted, and the ends 19, bear upon the sides of the link. This construction
would be advantageous where the rope is slack, as there will then be nothing to
cause the ring 14 to act as a lever to hold the plate tight against the rope. The
construction would also be advantageous where the rope was less in diameter than
the distance between the end of the plate and the hook, as the spring would hold
the plate against the hook, and the rope could not escape, in which case it would
not act as a clamp, but as a closed ring. For general use, however, I find that it
is not necessary to have the spring at all.
The clamp may be formed entirely out of wrought metal; but I prefer to form
it by casting, as the cost of production will be materially lessened.
Having now particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The improved rope clamp, constructed and operating substantially as
described with reference to the accompanying drawings.
2. A rope clamp, comprising a link provided with a hook extension; a plate
hinged to said link, the free end thereof being adapted to overlap a portion
of said hook extension; and means to hold the free end of said plate adjacent to,
or against said hook extension, consisting of an attaching device secured to the
under side of said plate, and fulcrumed on the housings forming the hinged
connection between the plate and the link, substantially as herein specified.
3. A rope clamp, comprising a link 5, having a hook extension 10; a plate 11,
having housings 12, and a housing 13; an attaching device 14, and a spring 17,
substantially as herein specified.
