Improvements in the Method of and Means for Repairing Hooks.
We, JOSHUA WILSON CARDER, Inventor, and SABINA JANE CARDER, no occupation,
both of Fort Worth, Texas, U.S.A., do hereby declare the nature of this
invention to be as follows:-
The object of this invention is to provide simple means for repairing hame
and like hooks which have been partly worn by friction, and which means can be
readily applied without much mechanical knowledge and with the use of few tools.
By this invention, I employ a steel spring which is bent to conform to the
inner contour of the hook, and is provided with side flanges adapted to fit over the
edges of the same. That part of the spring which comes opposite to the worn
portion of the hook is thickened and hardened and is bushed on its near side with
soft metal-such as lead-which can be easily beaten into the worn portion to
form a backing to the thickened and hardened portion of the spring. One free
end of the spring rests under the usual overhanging lug at the extremity of the
hook, whilst the other end enters a notch made in the end of the hook by means
of a file chisel or the like.
In an alternative form, a hole is drilled through the hook beyond the worn
portion. A circular rivet shaped piece of metal, having a head, is inserted and
has its other end slightly hollowed so that the annular edge surrounding the
hollow portion can be readily bent over to form a flange to retain the piece of
metal in place. The head of the piece of metal, and also its flange, projects over
the edge of the worn portion of the hook, and can be either beaten into it, or shaped
by means of a file, to conform to the contour of the inner edge of the hook.

COMPLETE SPECIFICATION.
Improvements in the Method of and Means for Repairing Hooks.
We, JOSHUA WILSON CARDER, Inventor, and SABINA JANE CARDER, no occupation,
both of Fort Worth, Texas, U.S.A., 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: -
Our invention relates to improvements in hame-hooks, and bushings for same;
and the object is to prolong the life of a hook indefinitely. The bushing is
intended to repair that class of hame hooks which are used with trace-chains.
When trace-chains are manufactured they are hardened, so that the links will

page_text: not wear out in the ends or bearings. It is necessary to harden chains because
the repairing of chains would be too expensive. Hame-hooks are left annealed,
so that they will not wear out the chains. Consequently the chain wears out the
hook in a short time. The hooks are usually as wide through the bearings as
the links of the chain permit; but this does not make the hooks last very long.
It costs as much, usually, to repair hame hooks as to buy new hames. We have
provided means by which hooks can be repaired over and over again at very small
cost.
Reference being had to the drawings hereunto annexed;-
Figure 1 illustrates a hook partly worn.
Figure 2 is a similar view, but shewing the hook prepared for repair.
Figure 3 shows the hook repaired.
Figure 4 is an end view of the bushing used in repairing the hook, and Figure
5 is a side view of the same.
Figure 6 shews the bushing with one head removed.
Figure 7 illustrates a bushing having a detachable head, and shewing how the
bushings become worn.
In order to repair a hook, worn as shewn at 1, I drill, or otherwise enlarge the
worn portion, by means of an instrument-such as a round file-into a circular
opening 2.
A bushing consisting of a rivet 3 having a head 4, and fitted with a removable
head or washer 5 is then inserted through the opening 2 and secured by rivetting.
The heads are then hollowed, as shewn at 6, to conform to the contour 7 of the
hook.
When the bushing becomes worn, as shewn in Fig. 7, it may be readily
removed and a new one substituted.
It will be understood that the removable head may be dispensed with and the
shank of the rivet be simply headed in the ordinary method of rivetting.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same. is to be performed, we declare that what
we claim is:-
(1) A bushing for hame hooks consisting of a solid body portion having heads
on both ends thereof, said heads having bearings for chain links, said bushing
being adapted to repair hame hooks, partly worn by friction of the links.
(2) The combination of a hook provided with an eye at the bearing point and a
bushing comprising a solid piece of metal which is provided with a head on each
end thereof and which is fitted in said eye.
(3) The method of repairing hooks consisting of forming the worn portion
of said hooks into a circular aperture and bushing the same with a double headed
rivet, substantially as hereinbefore described and illustrated in the drawings
hereunto annexed.
