Manufacturer 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 relates to improvements in shoeing horses and in the nails and caulks
employed for this purpose which differ from the ordinary horse shoe nails and caulks
by one or two ribs placed on the outer part of the head.
In the accompanying drawing,
Figures 1 and 2 show in front and side elevation a horse shoe nail made according
to my present improvements provided at one side of the head with a rib.
Figures 3 and 4 show a front and side view of a caulk or frost nail for horse shoes
according to my invention provided with a rib.
Figures 5 and 6 show a side and front view of a thicker nail also provided with
two projecting ribs on my new plan.
Figures 7 and 8 show a side and front view of an improved nail with two ribs like
Figures 5 and 6 but without a projecting head.
Figures 9 and 10 show steel pin caulks with two ribs and a hardened
head.
Figure 11 shows a horse shoe in which the nails shown in Figures 1 to 10 are
used.
Figure 12 shows a cross section from a to b of Figure 11 and a nail like Figures 1
and 2 driven into the horse shoe Figure 11.
Figure 13 shows a section from c to d of Figure 11 and also a nail like Figures 3
and 4 in the horse shoe.
Figure 14 is a section through Figure 11 on line e to f and shows the nail of
Figures 5 and 6 in connection with the horse shoes Figure 11. .
Figure 15 shows a section from 9 to h Figure 11 and a nail without head like
Figures 7 and 8 in connection with the horse shoe.
Figure 16 is a section on line i to k Figure 11 and shows the pin caulks or nails
Figures 9 and 10 in connection with the horse shoe.

page_text: Figures 17 and 18 show a side and front view of an altered form of the rib on the
nail head consisting of a slight arching thereof.
Figures 19 and 20 show the substitution for the ribs on the heads of the horse shoe
nails of shoulders cast on in the form of the section of a half sphere Figure 19 being
a side view and Figure 20 a front view.
Lastly Figures 21 and 22 show another position of the ribs at the head being placed
parallel to the surface of the horse shoo. Figure 21 being a side view Figure 22 a
front view.
As the holes of the horse shoe whether made by hand or by machinery are never
quite equal and in straightening the horse shoe they easily get somewhat displaced or
altered in shapo it is impossible for every one of the ordinary horse shoe nails to grasp
absolutely firm on to the hole. Consequently the horse shoe gets loose on the hoof and
the hoof itself suffers greatly.
Now horse shoe nails with ribs at the head made in accordance with my present
invention are designed to remove this evil. The horse shoe nails are as already
mentioned provided with one or two projecting ribs at the head which 11bs when the
nail is driven into the hoof in nailing on the horse shoe or when the shod animal stops
onto hard roads fill up the inequalities of the holes and under all circumstances fit
tightly in to the hole of the horse shoe.
The projecting rib or ribs work in this way that when the nail is driven in they
yield spread out and thus fill up or partly fill up the holes in the horse shoes in such a
way that the nails le properly in the holes on all four sides Thus the shoe is firmly
attached to the hoof and the hoof too is spared.
In Figures 1 and 2 a horse shoe nail with a projecting rib A is shown which nail
may be used instead of the ordinary nail for flat shoeing
Figures 11 and 12 show the horse shoe nail Figures 1 and 2 in connection with the
shoe. The projecting rib A is placed on one side of the four cornered wedge shaped
head and increases in height towards the base of the head so that it slightly increases
the width of the head. Figures 3 and 4 show a caulk or frost nail with a projecting
rib A. Figures 5 and 6 show a thicker nail or caulk with two projecting ribs A
and A. The nail Figures 3 and 4 is made of soft steel and hardened at the projecting
head part it can be used without any alteration for any horse shoe which is not ground
and is especially suitable for riding or light cart horses.
Figures 5 and 6 show a thicker nail with 2 ribs which as the thick cone is avoided
fit absolutely tight in the hole of the horse shoe It is made of soft steel with a
hardened head. In order to be able to use this nail however the holes of the horse
shoe must be widened
Figures 7 and 8 show a nail like Figures 5 and 6 with two ribs A A¹ but without
head.
Figure 13 shows the nail represented in Figures 3 and 4 in the horse shoe.
Figures 14 and 15 show the arrangement of the nails Figures 5 to 8 in the horse
shoe.
Figures 9 and 10 and Figure 16 show a steel pin caulk or nail with 2 ribs and a
hardened head. These pin caulks with ribs are driven in the usual four-sided nail holes
as shown in Figure 16.
-
The form of the ribs on the head part of the horse shoe nails as shown in Figures 1
to 16 may be altered by giving the ribs an arched instead of a straight outline and
instead of a wedge shape that of a projecting pad. Such ribs B Figures 17 and 18
only touch the hole with one point and therefore spread out better than the wedge
shaped ribs and form a better support for the nail head in the hole. The ribs B
(Figures 17 and 18) can also be replaced (as in Figures 19 and 20) by semi-spherical
or conical or other shaped shoulders (or elevations on the nail head the outer points
thereof lying in a straight line or a circular curve.
Lastly the ribs as in Figures 1 to 18 or elevations as in Figures 19 and 20 may also
be placed obliquely to the length of the nail (instead of in the transverse direction
thereof see the ribs D Figures 21 and 22) so that the nail head may enter the hole
with several such oblique ribs simultaneously

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1 Horse shoe nails and caulks with wedge shaped or circular outlined ribs at the
head parallel to the length of the nail which when the nail is driven in or when the
shod animal goes on to hard substances are spread out so that the nails or caulks
always have a firmer hold substantially in the manner and for the purposes hereinbefore
described and represented in the drawings hereto annexod.
2. Horse shoe nails and caulks with ribs at the head as claimed above but modified
by having the ribs oblique to the length of the nail substantially in the manner
and for the purposes hereinbefore described and represented in the drawings hereto
annexed
3. The substitution for the ribs at the head of horse shoe nails and caulks referred to
in Claims 1 and 2 of semi-sphere shaped, conical, or other shaped elevations C
substantially in the manner and for the purposes hereinbefore described and represented
in the drawings hereto annexed.
