PROVISIONAL SPECIFICATION.
Improvements in Spring Washers for Securing Screw Studs to Horse
Shoes.
I, GEORGE EAYRES, of 100 Hodgson Street, Sheffield in the County of York,
General shoeing smith, do hereby declare the nature of my said invention for
"IMPROVEMENTS IN SPRING WASHERS FOR SECURING SCREW STUDS TO HORSE SHOES
to be as follows:-
:-
This invention consists in the construction of a steel spring washer which
flied out separately or spun on a mandril and cut off in required lengths.
22
may be
One end of the said washer projects above the other and as the stud is screwed into
its place the washer is flattened out and the stud held firmly in position the spring of
the washer preventing it from becoming loose by any backward movement.
The material from which the said washer can be spun is thinner on the inner edge
than the outer so that the bind will be necessarily greater.
The studs when in use often break off at the screw and the shoes must be taken off
to get the said screw out but the washer will obviate the taking off of the shoe as that
portion of the screw covered by the washer will be sufficient to enable it to be removed
by pincers or other suitable instrument.

Improvements in Spring Washers for Securing Screw Studs to Horse
Shoes.
I, GEORGE EAYRES of 100 Hodgson Street, Sheffield in the County of York,
General Shoeing Smith, 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 consists in the construction of a steel spring washer, which may be
flied out seperately, or spun on a mandril, and cut off in required lengths. One end
of the said washer projects above the other as shown on annexed drawing; Fig. 1.-
And as the stud is screwed into its place on the shoe the washer is flattened out and
the stud held firmly in position as shown at Fig. 2, the spring of the washer preventing
it from becoming loose by any backward movement. The material from which the
said washer can be spun is thinner on the inner edge than the outer, so that the bind
will be necessarily greater. The studs when in use without the washers often break
off at the screw, when the shoes must he taken off to get the broken part of the
screw out; but the use of the washer will obviate the taking off of the shoes, as that
portion of the screw covered by the washer will be sufficient to enable it to be
removed by pincers or other suitable instruments.
Having now stated, particularly described, and ascertained the nature of my
invention, and in what manner the same is to be performed, I declare that what
I claim is
(1.) The use and construction of a washer as substantially described in the complete
specification, and illustrated in Figs. 1, 2, & 3 on the annexed drawing.
(2.) I especially claim the section of the washer, as shown at Fig. 3.
