PROVISIONAL SPECIFICATION.
A Hook with Spring to Hold Back-band Chain so as to Prevent
it from Slipping Out.
I, JOSEPH MULLIN of 6 Davis Place, Dublin, Ireland, Engineer do hereby
declare the nature of this invention to be as follows:-
This invention has reference to an improved spring hook for holding back-band
chains whereby same cannot slip out or come undone, and thus accidents to driver,
horse, or yoke are prevented.
In carrying out my invention I take an ordinary hook at its point I attach a
flat steel spring the free end of which impinges against the base of the hook.
As thus constructed the steel spring lies in a position across the entrance of the
loop of the hook and while it automatically yields to the introduction of a ring or
other coupling device it effectually prevents the escape of same until its (the spring's)
free end is depressed from contact with the limb of the hook whereupon the ring or
other coupling device can readily be released.
Hooks of this description are especially applicable for the attachment of back-
bands and such like purposes, for it is obvious that no matter how much the
coupling ring may be shaken or disturbed it cannot escape from the hook until the
spring is pressed back.
Dated this 20th day of January 1896.

A Hook with Spring to Hold Back-band Chain so as to Prevent
it from Slipping Out.
I, JOSEPH MULLIN of 6 Davis Place, Dublin, Ireland, Engineer, 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 reference to an improved hook for holding back-band chains,
whereby same cannot slip out, or come undone, and thus accidents to driver, horse,
or yoke, are prevented.
In carrying out my invention, I take an ordinary hook and at its point I attach
a flat steel spring, the free end of which impinges against the base of the hook.
As thus constructed the steel spring lies in a position across the entrance of the
loop of hook, and while it automatically yields to the introduction of a ring, or
other coupling device, it effectually prevents the escape of same until its (the
spring's) free end is depressed whereupon the ring or other coupling device can
readily be released.

page_text: The nature and action of my invention will be more readily understood on
reference to the accompanying drawings, in which
Fig. 1 is an elevation of the spring hook complete, and Fig. 2 an end view of
same.
A is the body of the hook and B the flat steel spring attached to the hook at C,
while its free end impinges against the base as shewn. D is the base collar whereby
the hook slides on the shaft bracket.
Hooks of this description are especially applicable for the attachment of back-
bands and such like purposes, for, it is obvious that no matter how much the
coupling ring may be shaken or disturbed it cannot escape from the hook until the
spring is pressed back..
Having now 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 :-
The use and application of a spring hook constructed, arranged and operating in
the manner and for the purpose substantially as herein specified and set forth.
