An Improvement in Lap-rings or Sister-hooks.
I GEORGE BOBB of Yokena, Warren County, Mississippi, United States of
America, Inventor, do hereby declare the nature of this invention to be as
follows :-
My invention relates to an improved lap ring or sister hook and has for its
object to enable the two members constituting the ring or sister hook to be readily
opened or separated when the article is to be connected with or disconnected
from any device to which it may be applied and to this end my invention consists in
connecting the two members by a loose joint forming a sort of swivel or practically
universal joint which enables the one portion of the ring or hook to be turned in
any direction in relation to the other. According to my invention the one member
is a hook of essentially oval shape having one end bent or curved to form an eye
at right angles to the plane of the hook while the other member is a shorter hook
having at one of its extremities an eye which is in the same plane as the hook and
engages or interlocks with the eye on the larger member.

COMPLETE SPECIFICATION.
An Improvement in Lap-rings or Sister-hooks.
I, GEORGE BOBB of Yokena, in the County of Warren and State of
Mississippi, United States of America, Merchant, 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 :-
Heretofore lap-rings have usually been so constructed that their members were
more or less difficult to open, or separate, as required to connect or disconnect the
rings from other devices.
My improvement consists in connecting the two members of the ring by a loose
universal or swivel joint which adapts it to be easily and quickly applied to or
detached from single and double-trees, chain-links, etc.
In the accompanying drawings,
Figure 1 is a perspective view of my improved lap-ring closed, and
Figure 2 is a perspective view of the same open.
The larger member A of my lap-ring is a hook of essentially oval shape having
one end bent or curved to form an eye a.
The other member is a short hook B

page_text: having on one extremity an eye b, which engages or interlocks with the eye a of
the larger hook A. The said eye a is at a right angle to the plane of the hook A,
and projects laterally from the same while the eye is in the same plane with the
hook B. By this construction I form a sort of swivel or practically universal
joint which enables the hook B to be turned in any direction with reference to the
other, and hence the lap-ring is adapted to be readily attached to or detached
from any part or device such as a single-tree, or double-tree, or chain-link, without
the aid of a hammer, chisel, or other tool, which is so often necessary-especially
in frosty weather-to separate the members of lap-rings of the usual kind or
pattern.
The lap-ring is distinguished not only by this adaptation for convenient and
rapid manipulation, but equally by strength and durability, since the joint or
connection between the two hooks is not formed by the aid of a pin, or rivet, as
usual in this class of devices, but by circular eyes, which are integral portions of
the respective hooks.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
As an improved article of manufacture, the lap-ring constructed, as hereinbefore
described, of the oval-shaped hook A having the integral circular eye a formed on
one of its extremities and projecting laterally from the body of the hook in a
plane at right angles to it, and the smaller shorter hook B having a similar
integral eye in the same plane with its body, the two eyes being interlocked as
shewn, whereby the smaller hook is adapted to be manipulated in the manner
specified.
Dated this 14th day of February 1894.
