Improvements in Horse Shoes.
We, MILTON CLARK GRAY, of Omaha, Nebraska, in the United States of
America, Importer and Dealer in Stock, and ALEXANDER CECIL GOFF, of Nos. 3
and 4, Bevis Marks, in the City of London, Gentleman, 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 improvements hereinafter described in horse
shoes.
The objects of the said invention are to provide a neat, simple, adjustable soft
tread horse shoe embodying a frog shield as hereinafter fully described and
further to provide a natural sole-bearing and frog supporting shoe, the shoe being
80 constructed as to automatically spread the heel.
By virtue of the said improved horse shoe there is provided a retention and
suitable supply of moisture to the frog and sole, the frog shield preventing any
bruising of the same and also preventing a descent of the pedal bone or dropping
of the sole, thus acting naturally upon the parts of the hoof, opening up the
heels, expanding the coronary band and providing full and free circulation to the
entire foot.
In the accompanying drawings, Figure 1 shows a bottom view of a two part
horse shoe certain portions embodying the said invention being removed.

Figure 15 represents a modification of the horse shoe in which the shoe in con-
junction with the frog shield is made of one part.
Figures 16 and 17 are respectively a sectional and outlined top view of this
last mentioned modification.
In the use of horse shoes as ordinarily constructed, the whole foot is raised from
the ground, the weight supporting area or surface being diminished nearly

page_text: or quite one-half, the bearing surface being distributed around the
three-quarter section of the outer circumference of the wall of the foot, this
narrow rim supporting all the weight of the animal. This overtaxing of the
same and the delicate structure connected thereto, often result in injury to the
foot. It has been conceded that one function of the frog is to support the navi-
cular bone in its arch directly under the second phalanx and between the wings
of the lateral cartilages Now, it has been pointed out that as ordinarily con-
structed the shoes leave the frog suspended, while in the herein described shoe a
cushion support is provided affording a protection to the under surface of the
animal's foot, stimulating and bringing into action the great base of the arch.
From this it will be seen that this invention provides a natural sole-bearing frog
support, and that the inclination of the upper rear section of the shoe, as herein
disclosed, further provides an automatic heel spreador, operative through the
structural peculiarity of the shoe, the frog pressure or support and heel spreador
acting in conjunction to insure a free and complete digital circulation, aiding in
preventing congestion or extravasation of blood at any point in the plantar region.
In recapitulation, it may be stated in the fewest words, that this invention
provides a soft tread heel spreading, frog and sole supporting horse shoe.
The said invention embodies essentially a horse shoe which is made either in
one piece or two similar half sections and these half sections comprise the rear
or heel portions 1, the intermediate corrugated portions 2, and the forward por-
tion 3, as is clearly shown in Figure 1. These two similar shoe sections are
approximately in the shape of an 1-beam in cross-section, the downward and
upward extending flanges, however, being of unequal length, the depending
flange preferably being a little longer than the upwardly extending flange, as may
be noticed in referring to Figures 2, 4, 7 and 9.
In referring to Figure 4 which represents a sectional view on lines 22, 2³ of
Figure 1, it will be noticed that the central portion of the main plate A, of the
shoe, is of an equal thickness. That portion, however, of the shoe near the rear
and marked 1. is preferably made to slant upward and inward as is shown in
Figure 2, which represents a view on lines z, z, of Figure 1, and as these rear or
heel sections 1, of the shoe both slant inwardly, the animal's heel is (naturally
always tending to shift outward upon both sides, insuring a gentle spreading of
the heel as no nails are driven in the rear portion of the horse's hoof. These two
shoe sections are provided at suitable points within the corrugated portion 2, of the
shoe. with suitable nail openings 5, preferably positioned near the outer flange b,
as disclosed in Figure 1. At their forward edges 3, the two shoe sections are
united by means of a suitable rivet C. which passes through an opening within
each shoe section to movably connect them.
To further insure a metal surface near the forward portion of the shoe, which
is adapted to receive the greatest strain, the extending wedge shaped ribs 13. 13,
are provided, as is shown in Figures 1 and 7. The flanges b. are preferably
corrugated their full length at the points where the nail holes are positioned, as
is shown in Figure 1.
In referring to Figures 2, 3, 4, 6 and 7, it will be noticed that by means of the
flanges, a retaining web is provided and this retaining web is used to hold the
upper non-conducting material 18, which comes adjoining the wall and sole of
the horse's foot and may be of compressed fibrous material or any other suitable
substance, while another depending flange is bent iust a little inward and so
forms a biting nib for the elastic tread 1, of any suitable material, as has been
shown.
In referring to Figure 2, the upper surface of the upper filling 18, is shown as
slanted by the line z, and this slanting is what insures the hoof naturally spread-
ing outward. Now, in order to provide a suitable support for the frog, a shield
is provided which in cross-section is in the shape of an T- beam, having a short
upper and long lower flange provided with an upper filler or cushion 8. of any
suitable material, and a lower elastic tread 1, as is shown in Figure 3. This frog

page_text: shield is adjustably held within the shoe in being provided with the outwardly
extending plates 7, which are provided with suitable holes so as to accommodate
the rivets 12, which rivets 12, pass through the body of the shield, the plate 7, and
below are secured to a suitable plate 10, so as to more snugly secure these platesī,
and keep them away from the filler or tread 1, which is immediately below this
plate 10. The two hinged shoe sections are next provided with the preferably
conical pins 6, the conical heads of which preferably pass through an opening
within the tread 1, then through the plates 7, and finally having its upper end
bushed so as to snugly and securely connect the plates 7, 7, to the hinged shoe
sections. By this means it will be noticed that there is provided a two part horse
shoe, pivotally connected by means of the pin c, and provided with an upper non-
conducting bed 8, adapted to receive the horse's hoof and a lower soft tread 1.
A frog supporting shield is further provided which touches the ground its full
length and is adapted to support the frog of the horse's hoof. This frog shield
is movably held so that in case any stone should work into the shoe, the frog
shield can be adjusted to remove the same. It will further be noticed that by
virtue of the corrugations, these shoe sections may be curved so as to conform
to the different shaped feet.
Referring to, Figure 5, it will be noticed that the chain links i, i, are shown,
which are connected by means of pins e, and within which are shown the horse
shoe nails D. These chain links are cast within the lower soft tread 1, and while
thereby the tread is securely secured to the shoe sections, they are movably and
elastically held and supported.
In Figure 6, a central sectional view disclosing the position of the nails has
been shown. This embedded chain is of special service where the shoe is used in
conjunction with dray and draft animals. The body portion A, of the shoe may
be perforated, as is shown in dotted lines in Figure 8, so that the upper filler
and lower tread may be of one substance and cast about the shoe.
In Figure 8, is shown a one piece horse shoe with corrugated edges but the
body A, of which is provided with a series of perforations marked 6. The shee in
this instance is provided near the heel portion with the slots 8, so that the frog
retaining bar 10, can be inserted into it, these openings 8, being secured by
means of the pins 12, as has been described. A frog shield C is provided which,
however, is also provided with perforations, as is shown in the dotted line, and
further having a slot 11, so that the bar can pass through this slot, the frog
shield C, being secured to the bar 10, by means of the pins 13.
Figure 14 shows a one piece frog shield C provided with the outwardly extend-
ing arms 10, and this shield with the integral arms is nicely adapted to be used
in conjunction with the two part shoe shown in Figure 1. The shield C, is pro-
vided with the perforations a, so that the tread and supporting cushion can be
readily cast thereon.
In Figure 15, is shown a still further modification in which the shoe and frog
pressure or supporting shield are cast in one part. The shoe in this instance
being provided with the usual flanges B, while the forward portion of the shoe is
provided with the corrugations 5,5, body A, of the shoe being perforated in
having a series of openings 2,2, in addition to the nail holes 3, as is shown upon
the one side in Figure 15.
In Figure 16, a sectional view of this modification is shown.
In order to insure this one piece horse shoe being made adjustable to various
sizes, the shield is split so that it may be opened in adjusting the same, as is
shown in Figure 17.
In the construction of a horse shoe according to this invention any suitable
material may be used for the tread and cushion, and so, also, may any metal be
employed. It is found, however that a convenient method is to cast the shoo
proper in aluminium which is then subjected to a great pressure, this shoe being
finally provided with a tread and cushion.
The device is noticeable because of its simplicity.
