page_text: I, STOVER MOON of Green, in the county of Clay and State of Kansas one of
the United States of America, Blacksmith and Machinist 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:-
My invention relates to an improvement in hoof-parers.
The objection to the parers hitherto in common use has been that there was not
sufficient space between the abutment-jaw and the knife-jaw to admit of the
attachment thereto of a suitable paring-knife, or if such distance were obtained
there was a lack of sufficient purchase to make the parer operate easily. It has
also been customary to provide the abutment with a slot adapted to receive the
blade, which construction is apt to cause delay and annoyance on account of
clogging.
The object of my present invention is to provide a parer which will not clog,
will be capable of being operated with ease, which will automically open, and the
handles of which will not close tightly enough to pinch the fingers.
A further object is to provide a strong, durable, and comparatively inexpensive
parer adapted to general use in preparing a horse's hoof for the shoe.
With these ends in view my invention consists in certain features of construction
and combinations of parts, as will be hereinafter described, and pointed out in the
claim.
In the drawing is shown a perspective view of my device, in which A A' represent,
respectively, the abutment and the knife-jaw of the parer, and a a¹ represent the
handles attached to said jaws. The handles are pivoted or hinged together by a
bolt, B-for example, after the manner of shears. The jaws A. A', as they leave
the pivotal point B, turn at an angle of about ninety degrees with the handles,.
and after extending the proper distance (two inches, more or less) they curve
around toward each other, terminating in cross-heads C C₁. The head Cis slightly
concave on its face, to adapt it to the curve of the borse's hoof, and is made
sufficiently heavy to form a strong solid abutment against the edge of the hoof to
be pared. The cross-head C is cut away on its outer side, as shown at D, forming
an extended seat for the reception of the back of the knife E. The knife E is
slightly curved in the direction of this length, and its edge e is also made rounding,
to better adapt it to force its way through the hard hoof. The knife is secured to
UCL

page_text: the crosshead C¹ by means of a pair of screws, d, which extend through perforations
formed therein, and into threaded sockets or perforations, formed in the head.
When in position, the outer or convex side of the blade is flush with the outside
of the head C¹, and the heads of the screws d'are countersunk flush with the surface
of the knife. As the jaws close, the edge of the blade shuts past the inner edge of
the abutment C, and, in conjunction therewith, forms a shearing cut, which severs
the shaving from the hoof at the outer or horny surface thereof. The handles, as
they extend from the pivotal bolt, make a slight curve toward each other, as
shown at g, and then diverge for a short distance, after which they run parallel
with each other to a point, h, near their extreme end, where they curve slightly
outwardly to prevent them from sliding too freely out of the grasp of the operator.
A spring I, is secured at one of the ends, to the inside of one of the handles, its
free end resting in contact with the inside of the other handle near the pivotal
.bolt, and serving to cause the handles to automatically separate and the jaws to
open when the grasp is released. The curve of the jaws, while admitting of a
wide separation of the ends of the jaws, and hence of the introduction of a suitable
blade or knife, at the same time brings the point where the work is performed,
only a short distance from the pivotal point, and hence admits of exerting great
force upon the cutting-edge with a slight expenditure. of power on the handles.
The means for preventing the handles from meeting at the point where the hand
is applied is also simple and effective, while the introduction of the spring enables
the operator to use the instrument with one hand, as the jaws clear themselves and
open for a new cut. There being no slot for the reception of the knife-edge, no
wedging or clogging occurs, and the instrument as a whole is simple, strong, and
handy.
It is evident that slight changes might be resorted to in the form and arrange-
ment of the several parts without departing from the spirit and scope of my
invention; hence I do not wish to limit myself strictly to the construction herein
set forth.
Having now particularly 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 :-..
In a hoof-parer, the combination, with a pair of pivotal jaws branching
outwardly from the pivotal joint, and then curving toward each other, as shown,
one of the said jaws having a concave-faced abutment on the free end thereof and
the other jaw having a blade secured to the free end thereof, of the handles secured
to the jaws and curved or bent toward each other near the pivotal point of said
jaws to form a stop, and a spring interposed between the handles, all of the above
parts constructed and combined substantially as set forth and illustrated in the
drawing annexed.
