page_text: LETTERS PATENT to John Saxby, junior, of Albert House, Canterbury Terrace,
Kilburn, in the County of Middlesex, for the Invention of "IMPROVEMENTS IN
HORSE-SHOES.'
"
Sealed the 28th February 1879, and dated the 23rd December 1878.
PROVISIONAL SPECIFICATION left by the said John Saxby at the Office of the
Commissioners of Patents on the 23rd December 1878.

of Middlesex. "IMPROVEMENTS IN HORSE-SHOES.'
"
My Invention relates to a construction of horse shoes, and mode of fixing them,
so as to avoid the penetration of the hoof by nails. I make a metal casing or
upper in halves, jointed together at one part, and secured by a bolt and lock nut,
rivet, or twisted wire at another part, the said casing being made of dovetail form
in section, and its upper part extending some distance up the slope of the hoof, so
that when it is opened on its joint it can be placed on the hoof, and then being
closed it can be securely clamped thereon, the dovetail form of the hoof holding it
in position. The wearing or under part of the shoe may either be formed as a lip
or flange in one piece with the casing at its lower edge, or it may be made in a
separate piece or in two pieces, screwed or rivetted, or secured by dovetails or other-
wise to the lower lip of the casing.

JOHN SAXBY, junior, of Albert House, Canterbury Terrace, Kilburn, in the County
of Middlesex. "IMPROVEMENTS IN HORSE-SHOES.”
My Invention relates to a construction of horse-shoes, and mode of fixing them,
so as to avoid penetration of the hoof by nails, as I will describe with reference to
the accompanying Drawings, and the figures and letters marked thereon. Figs. 1,
2, 3, and 4 shew one construction which I employ, Figs. 1 and 2 representing side
views, and Fig. 3 a front view of a hoof, with a shoe fixed thereon according to my
Invention, and Fig. 4 being a plan shewing the part beneath the hoof From these
Figures it will be seen that a metal casing or upper made in parts jointed together
is clamped on the hoof, the dovetail form of which holds it in position, and that the
lower part of this casing receives the tread or wearing part of the shoe. When
the tread is worn the casing is unclamped from the hoof, a new tread is fixed to it,
and the casing with the new tread is again clamped on the hoof, which by this
arrangement is saved from being penetrated by nails, as is the case when ordinary
shoes are fixed thereon. The casing or upper shewn in the Figures referred to is
made of open work to save weight, and is constructed as follows:-A is the under
-piece, of horse-shoe shape, to which is fixed the tread B, either by rivets, or prefer-
ably by screws b, as shown, these screws being prevented by the hoof from becoming
unscrewed when the shoe is on. To the piece A are fixed two side ears C, C¹, and
a front ear D; these ears may be screwed or rivetted to the piece A, or they may
be made in one piece with it. To one of the side ears C is rivetted a flexible metal
strap E, which passes round the upper part of the hoof, and has near its farther end
a slotted hole. The other ear C terminates in a tongue piece c, which at first is
bent outwards horizontally, so as to be inserted in the slot of E, and is then bent
down, fixing the end of E in position. To the front ear D is attached a strap F,
which extends up the front of the hoof. It has a tongue piece ƒ punched forward
and bent up to bear against the under edge of the strap E, and its upper end is
bent over the upper edge of E, so that the middle of E is held steadily in position.
When it is required to remove the shoe, the tongue c is bent up to a horizontal
attitude, and the end of the strap E is thus released, so that the whole casing and
shoe can be removed from the hoof. Between the metal of the casing and the hoof
I interpose a lining G of caoutchouc or soft elastic fabric, so as to make a soft bedding
for the parts, and prevent jar and vibration. A modified form of the casing and
the means of fixing it on the hoof is shewn in front view at Fig. 5, and in side
view at Fig. 6; a vertical section through the front part is shewn at Fig. 7, and
sectional plans on X, X, and Y, Y, respectively are shewn at Figs. 8 and 9. According
to this construction the upper strap is made in two parts E and E¹, each rivetted at
their back ends to one of the side ears C, C¹. Their front ends are bent over and
rivetted to form loops e, e', interlacing with one another, and with a part ƒ of the
front strap F, which is punched forward in form of a staple. A key or wedge H
is driven through the loops e, e¹, and staple f, and to prevent it from being slackened
out, its lower end is bent forwards, as shewn. For unclamping the shoe the key H
is straightened and driven out, and the casing straps thereupon open apart, allowing
the casing and shoe to be removed from the hoof. Although I have shewn two
modes of clamping the casing on the hoof, it is obvious that other means for fixing
the jointed parts together might be adopted, as, for example, bolts and nuts passed
through overlapping eyes, or a piece of wire passed through meeting eyes and twisted;
also, the lower part of the casing might itself be the tread or wearing face of the
shoe, instead of making that as a separate piece fixed to the former, as shewn; and
farther, when the construction shewn in Figs. 5, 6, 7, 8, and 9 is adopted instead of
making the ears C, C¹, and D as separate pieces, to which the straps E, E¹, and F

page_text: are rivetted, these straps may themselves be bent inwards at their ends, and secured
by screws or rivets to the under piece A.
Having thus described the nature of my Invention and in what manner the same
is to be performed, I claim,-
First. The method, substantially as herein described, of fixing a horse-shoe by
making it part of or attached to a jointed metal casing or upper that is clamped on
the hoof, so as to be held thereon by the dovetail form of the hoof, thereby avoiding
penetration of the hoof by nails.
Second. Constructing the casing referred to in the preceding claim of an under
piece of horse shoe form, with flexible metal straps attached thereto, and secured
to one another, substantially as herein described with reference to the accompanying
Drawings.
In witness whereof, I, the said John Saxby, junior, have hereunto set my hand
and seal, this Seventeenth day of June, in the year of our Lord One thousand
eight hundred and seventy nine.
