Detachable Sharps, Blunts, and Toe-pieces and other Improvements
in or Additions to Horse-shoes, rendering said Shoes adaptable
for Use on either Hard or Soft Roads.
I, AGNES DONNELLY, Carriage Hirer, residing at 94, Church Street, Dumbarton,
in the County of Dumbarton, North Britain, do hereby declare the nature of this
invention to be as follows:-
The said invention relates to a detachable sharp or blunt and also to a detachable
toe-piece whereby any of the aforesaid pieces is rendered readily attachable or
detachable being held on securely by means of my fish-hook expansion prong.
Hitherto, these sharp pieces or blunt pieces otherwise called sharp; and blunts
have been permanently fixed into an oblong or square recess in the horse shoe. My
invention seeks to obviate the difficulties that have, hitherto, attended that permanent
arrangement of sharps, blunts and toe-pieces.
In carrying my invention into practice I use for the purpose of holding on any of
the aforesaid pieces what are herein designated fish-hook expansion prongs.
These prongs, as the name implies, are made of the finest tempered steel and are
composed of two arms right and left respectively and at the extreine ends of the said
arms I have fixed thereto fish-hook catches or in other words a fish hook catch
at the extremity of each arm. In fixing on to the horse-shoe a detachable sharp,
blunt or toe-piece, as the case may be I insert the oblong or square catch
into the horse-shoe in the usual manner and through said oblong or square
catch there being a hole or aperture in line with hole or aperture in the
horse-shoe I then insert the two catch-points of the fish-hook catches and having
done so drive same through said aperture and on their arrival at the extreme
end of this aperture they automatically expand the one to the right and the other to
the left and thereby hold the toe-piece, sharp or blunt securely in position until said
piece (sharp or blunt) is wanted to be detached. In detaching saine, the operation
is of course, the inverse order of the preceeding and in which case I press the
two fish-hook catches close together and thus having cleared the catches on right
and left they then easily glide along said aperture and are forthwith extracted after
which the piece hitherto held by means of my fish-hook expansion prong instantly
falls out and assuming that I have detached a sharp I in its place immediately attach
a blunt. These fish-hook expansion prongs can be made with one arm plain and
with the other arm having the fish-hook catch but are preferably made with both
arms having the fish-hook catch.
+
As a modification of my fish-hook catch I use two plain arms and after having
inserted said two plain arms destitute of the fish-hook catches I have said arms
opened out at the extreme ends by means of a tool and in which catch arrangement
they hold on the toe-piece, sharp or blunt as the case may be.
Toe-pieces sharps or blunts as ordinarily used do not rest upon the shoulder but
with my automatic fish-hook catches I am thereby enabled to make the aforesaid
pieces rest totally with their shoulders resting against the shoe and my fish-hook
prongs with their automatic clench power having nothing more to do than merely

Detachable Sharps, Blunts and Toe-pieces and other Improvements
in or Additions to Horse-shoes, rendering said Shoes adaptable
for Use on either Hard or Soft Roads.
I, AGNES DONNELLY, Carriage Hirer, residing at 94, Church Street, Dumbarton, in
in the County of Dumbarton, North Britain, 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 :-
The said invention relates to improvements in horse-shoes, in so far as it relates to a
-detachable sharp or blunt piece and detachable toe-piece or to detachable sharps,
blunts and toe-pieces, whereby the said pieces are rendered readily attachable and
detachable, being securely held by means of fish-hook expansion prongs, or with
prongs having two plain arms, otherwise called, in its entirety, a split-pin, the said
split-pin having two plain arms. Hitherto, these horse-shoe sharp pieces or blunt
pieces, otherwise called sharps or blunts, have been permanently fixed into the horse-
shoe, or, at least, fixed in such a manner as to render their tenure or holding power
uncertain and their insertion or extraction, while on the road, at all times, a difficulty.
. My invention seeks to obviate these difficulties that have, hitherto, attended that
..permanent or undetachable arrangement of sharps, blunts and toe-pieces. In carrying
my invention into practice, I use, for the purpose of holding on any of the aforesaid
pieces, fish-hook expansion prongs, or, as a modification of same, I use, two plain
arms, and, after having inserted these two plain arms destitute of the fish-hook catcb,
..I have them opened out, and, thereby, rendered capable of holding on to the toe-
piece, the sharp and the blunt, as the case may be. These fish-hook expansion
prongs can be made with one arm plain and with the other arm having a fish-hook.
catch, but are preferably made with both arms having a fish-hook catch, or, with
both arms plain and thus destitute of fish-hook catch.
The object of my detachable sharps, blunts and toe-pieces in horse-shoes is to give
a degree of certainty in the holding power of said pieces, hitherto, unattained, and,
along with that, an easier mode of attaching and detaching the afore-named pieces.
An assortment of these pieces, with a corresponding quantity of prongs to suit, can
be carried, in the pocket, and, held for any emergency on the road.
In order that my said invention and the manner of performing or carrying same
into practice may be understood, I have, hereunto, appended one sheet of drawings,
in which the same letters and numerals are used to designate the respective parts in
all the figs., wherein shewn.
"
Fig. 1 is an elevation view of fish-hook expansion prongs.
Fig. 2 is an elevation view of split-pin, or modified prongs.
Fig. 3 is an elevation view of longitudinal sharp.
Fig. 4 is an elevation view of latitudinal sharp.
Fig. 5 is an elevation view of toe-piece.

The descriptive account is as follows:-
Fig. 1 is an elevation view of fish-hook expansion prongs.

page_text: F is the fish-hook expansion prongs with two arms; F¹, the fish-hook catches
on F; F, head of F.
In this fig. as also in Fig. 2 the enlarged sizes are given, as compared with the
other parts of drawings, and which is done for explanatory purposes.
Fig. 2 is an elevation view of split-pin or modified prongs.
P is the split-pin with two arms; P, the points of arms of P'; P2, head of P.
These prongs, as the name implies, are made of the finest tempered steel and
composed of two arms, right and left respectively, and, at the extreme ends of said
arms, I have fish-hook catches (as seen in Fig. 1), or, in other words, a fish-book
catch, at the extremity of each arm. In Fig. 2, the arms, being destitute of a fish-
hook catch, are opened out by means of pliers or other suitable tool and turned
outwards, as seen in Fig. 6.
In Fig. 7 the fish-hook prongs, as seen in Fig. 1, are used, and, they acting
automatically, do not require to be turned outwards, as they immediately expand,
right and left, and thereby hold the toe-piece, sharp or blunt securely until wanted
to be detached.
Fig. 3 is an elevation view of longitudinal sharp.
S is the elevation end-view of longitudinal detachable sharp; S¹, the elevation
front-view of saine; S, shoulders of same, resting totally against the shoe. O is
square catch of sharp. A is the hole or aperture through (.
The shoulders marked, herein, S4, applies in like manner to sharps, blunts or toe-
pieces as the case may be.
O is the oblong or square catch on sharp, blunt or toe-piece, and, is, as the name
implies, either square or oblong, but preferably it is oblong, on the toe-piece and
invariably square, in all the other pieces.
Fig. 4 is an elevation view of latitudinal sharp.
S is an elevation front view of latitudinal detachable sharp; S³, elevation end-view
of same; S, shoulder of same, resting totally against the shoe.
O is the square catch of sharp. A is the hole or aperture through O.
Fig. 5 is an elevation view of toe-piece.
T is elevation front-view of detachable toe-piece; T¹, elevation end-view of same;
St, shoulder of same, resting totally against shoe.
O is the oblong catch, in toe-piece.
A is the hole or aperture through oblong catch, O.
Fig. 6 is a top-side plan-view of left-foot horse-shoe.
A is an oblong aperture or slot, in horse-shoe, for the insertion of O. A² is a
square aperture or slot, in horse-shoe, for the insertion of O. A³ is the same as A².
H is a hole or aperture, preferably a round hole drilled, through horse-shoe in line
with A a hole similarly inade and through which either P1 or F¹ is inserted, as the
case may be. P¹ are points of arms of P; P2, head of P.
The attachments in this left-foot horse-shoe would be as follows:-
T, as shewn in Fig. 5, would be with its oblong, O, inserted into the oblong
aperture, A¹; the longitudinal sharp, S, as seen in Fig. 3, would likewise be inserted
into aperture A³, and the latitudinal sharp, S, as seen in Fig. 4, would be likewise
inserted into aperture A2. Having inserted these attachable and detachable
sharps, P¹ would, in all three cases, be thrust through H of horse-shoe and A of sharp
or toe-piece, as the case may be, and, thus, attached securely until wanted to be
detached. This done, the points, P¹, would be turned outwards with or by means of
pincers or other suitable tool or instrument and hammered into position, as seen in
drawing. In this fig., as also in Fig. 7, the sharps, as shewn in Figs. 3 and 4, and
toe-piece, as shewn in Fig. 5, are not inserted, P only, as will be seen in Fig. 2, being
inserted. In fixing on a detachable sharp, blunt or toe-piece, as the case may be, I
insert the oblong or square catch into the horse-shoe, and through said oblong or
square catch there being a hole or aperture, in line with hole or aperture in the horse-
shoe, I then insert the fish-hook catches, and afterwards drive same through said
aperture, and, on their arrival at the extreme end of this aperture, they immediately
expand, right and left, and, thereby, hold the toe-piece, sharp or blunt securely until

page_text: wanted to be detached. In using the split-pin, as shewn in this fig., pincers are used
to open the points, P¹, and afterwards said points are hammered into the position as,
herein, shewn.
The head P or º, as the case may be, can be countersunk, and the points, P¹
or F, as the case may be can, in like manner, be recessed or countersunk.
In the case of using blunts, the operations of attaching or of detaching are
exactly the same, and having inserted one sharp or toe-piece, the insertion of
another sharp, blunt or toe-piece (either blunt or sharp), is done in exactly the same
manner.
Toe-pieces, sharps or blunts, as ordinarily used, do not rest upon the shoulder, but
with my automatic fish-hook catch-prongs, or its equivalent, the split-pin, I am,
hereby, enabled to make the aforesaid pieces rest bodily with their shoulders totally
against the shoe, and my automatic expansile fish-hook prongs having nothing to do
more than merely hold on the detachable pieces, the whole weight of the horse is
resting bodily upon the said pieces, all as aforesaid.
Fig. 7 is a top-side plan-view of a right-foot horse-shoe.

H is a hole
A is an oblong aperture, in horse-shoe, for the insertion of 0. A
aperture, in horse-shoe, for the insertion of O. A is the same as A.
or aperture through horse-shoe, in line with A, and through which either P¹ or F¹ is
inserted. Fare fish-hook catches, on F; F2, head of F.
The attachments in this right-foot horse-shoe would be as follows:-
T, as shewn in Fig. 5, would be with its oblong, 0, inserted into the oblong
aperture, A. The longitudinal sharp, S, as seen in Fig. 3, would be likewise
inserted into aperture, A", and thus it will be seen that the right-side of Fig. 6
and the left-side of this fig. would have the longitudinal sharps.
The latitudinal sharp, S2, as seen in Fig. 4, would be likewise inserted into
aperture Aº, and thus it will be seen that the left-side of Fig. 6 and the right-
side of this fig. would have the latitudinal sharps.
In Fig. 6, the prongs, as shewn in Fig. 2, are used, whereas, in this fig., the fish-
hook prongs, as shewn in Fig. 1, are used.
In these two Figs., 6 and 7, neither sharps nor blunts are shewn, as fixed therein,
but the respective places they would occupy when fixed. Assuming that either
sharps or blunts were inserted into the apertures A4, A5 and A6, the points, F1, would
be thrust through H, in line with A, and immediately expand, right and left, thereby
holding the toe-piece, sharp or blunt, as the case may be, securely fixed until wanted
to be detached. In detaching same, the operation is, of course, the inverse order of
the preceeding, in which case I press the two fish-hook catches close together and
having cleared the catches of the right and left side they easily glide along said
aperture and are extracted, after which the piece, hitherto, held by means of my
fish-hook expansile prong instantly falls out, and, assuming that I have detached a
sharp, I, in its place attach a blunt, or I can leave the shoe without either sharp or
blunt, all as seen in Figs. 6 and 7.
Having now particularly described and ascertained the nature of my said inver
tion, and, in what manner the same is to be performed, I declare that what I
claim is
First. The method of manufacturing or constructing a horse-shoe with attachable
and detachable sharps, blunts and toe-pieces, substantially as, herein, described in
reference to and shewn in the accompanying drawings.
Second. A horse-shoe fitted with attachable and detachable sharp pieces (or their
equivalents, blunt pieces), as shewn in Figs. 3 and 4, with or without attachable and
detachable toe-piece, (sharp or blunt), as seen in Fig. 5 (illustrating sharp), fitted
into apertures or slots, A1, A2 and A3, as seen in Fig. 6, with prongs, P, passing
through apertures, H and A, simultaneously, all as specifically described and shewn in
the accompanying drawings.
Third. A horse-shoe with attachable and detachable sharp pieces, as shewn in
Figs. 3 and 4, with or without attachable and detachable toe-piece (sharp or blunt),

page_text: as seen in Fig. 5 (illustrating sharp), fitted into apertures or slots A4, A5 and Aº, as
seen in Fig. 7, with prongs, F, passing through apertures, H and A, simultaneously,
all as specifically described and shewn in the accompanying drawings.
Fourth. A horse-shoe with attachable and detachable sharps, as per claims second
and third, hereof, held by means of prongs, F, as shewn in Fig. 1, or by means of
prongs, P, as shewn in Fig. 2, all as specifically described and shewn in the accom-
panying drawings.
Fifth. A horse-shoe with attachable and detachable sharps or blunts or toe-pieces
(sharp or blunt) held on by means of either kind of prongs, F or P, all as specifically
described and shewn in the accompanying drawings.
