PROVISIONAL SPECIFICATION.
Improvements in Horse Shoes.
I, RICHARD MCDOUGALL of 25 Wellington Street, in the City of Glasgow,
Commission Agent, do hereby declare the nature of this invention to be as
follows:-
This invention is a development of the improvements in horse shoes described in
the Specification of Letters Patent granted to me No. 2916 of 1886 and it has for
object mainly to simplify the construction and reduce the cost of production of horse
shoes which are designed for attachment to the hoof without the use of nails.
In a jointed shoe, I secure in grooves dovetailed or otherwise formed in the under
side of the shoe at the toe and heel or other parts, calks having formed upon them
ribs or flanges which when the calks are in place the ribs or flanges project
outwards and are bent upwards over the edge of the shoe and over the hoof and by
gripping the hoof serve to retain the shoe thereon after it has been fitted. The
calks may be of any suitable dimensions or shape and may be made plain, serrated
or roughened and the ribs or flanges may be bound together at or near their upper
ends by a band or bands of metal, leather or other material formed in one or more
parts, the jointed shoe being clasped and securely bound upon the hoof by a band,
strap or bolt and screw or other locking device passing behind the heel part or as
in my former Specification above alluded to. The calks may also have a flange on
the inside to bend up over the shoe to afford additional security, and the jointed shoe
itself may be made partly or wholly plain, serrated or roughened. In order to lessen
the cost of production, I prefer to employ a solid or non-jointed shoe either plain,
serrated or of arched form or roughened in whole or in part or with solid calks of
like kind, moulded, forged or cast thereon, or having removable calks and ribs
adapted thereto in the manner already set forth in this and in my former Specification;
and for the purpose of securing it to the hoof 1 employ either the devices above
mentioned or those described in the Specification of my former Patent before referred
to or both. Or the ribs or flanges may be forged or cast, moulded or otherwise
formed in a piece with the shoe or made separate and passed through holes or slots
therein and bent up over the hoof to secure the shoe permanently to the foot or they

page_text: may be made removable in accordance with my former Patent in order to admit the
hoof and permit of the shoe being taken off the foot and replaced at pleasure and
with or without base pieces passing through slots or dovetailed or other form of
grooves in the shoe, and secured on one-or both sides of the shoe by screws, bolts,
split pins, cotters, or other devices passing through the shoe to retain the ribs or
flanges in position in the shoe and bearing against the hoof.
The removable or unremovable rear rib or flange on both jointed or solid non-jointed
shoe which may be applied either on both sides of the hoof or at the outside only is
or may be of curved or arched form extending forward and having a bearing along
the wall of the hoof so that while having a secure grip it may not unduly press on or
injure the foot, or the rear ribs may be made to extend round the hoof and be secured
to the front rib or ribs by'a screw or other device. For a like purpose the ribs or
flanges are preferably lined with a cushioning of leather, cloth, rubber or other
suitable material and a pad or cushioning may also be placed between the shoe and
the hoof. A band of metal or other suitable material formed in a single piece or in
two or more pieces may be run round the hoof connecting the ribs or flanges at or
near the top and secured either in front of or behind the hoof or to the hind ribs
by screws or other suitable means serving to give increased grip on the hoof, and
the hind ribs or flanges may be bound together at the top by a bolt and screw or
other locking device passing over the hind part of the foot below the fetlock.
In some cases I secure together the shoe and the ribs, or flanges by passing through
them and the lower part of the wall of the hoof screw bolts, or other fastenings which
pierce and pass through the hoot at the solid part at such an inclination that they
do not injure the foot said bolts or screws being secured by screw nuts, split pins,
cotters or other devices.
For horses which brush or cut the fetlock joint I form a shoe having the inner side
sufficiently flattened, and pare off the edge of the hoof correspondingly.
For tender hoofs and to prevent injury to the hoof by stones and the like a thin
plate of sheet metal may be fitted across the hoof between the hoof and shoe said
plate being cut away at the rear to clear the frog and a cushioning of leather or other
soft material being so attached to the plate as to cover the frog.

page_text: I RICHARD MCDOUGALL of 25 Wellington Street in the City of Glasgow Com-
mission Agent 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 is a development of the improvements in horse shoes described in
the Specification of Letters Patent granted to me No. 2916 of 1886 and it has for
object mainly to simplify the construction and reduce the cost of production of horse
shoes which are designed for attachment to the hoof without the use of nails.
In the accompanying drawings which illustrate my invention figure 1 is a plan,
figure 2 a side elevation and figure 3 an inverted plan of a modification of the improved
horse shoe as secured to the hoof by means of removable clips in lieu of nails;
figure 4 is a plan and figure 5 a side elevation of a modification of the improved shoe
in which the securing clips are forged or otherwise formed on the shoe one of the rear
clips being made removable to enable the shoe to be fitted to the hoof; fignre 6 is an
elevation and figure 7 a part plan of a similar shoe but showing modified means for
attaching the removable clip; figures 8 and 9 are elevations showing modifications of
the shoe figure 10 is a plan of a jointed shoe as constructed in accordance with my
invention which may be jointed at toe or on one or both sides of heel, figure 11 is a
plan of a shoe showing means for securing and tightening up the rear clips on the
hoof, and figure 12 illustrates an improved shoe in which the removable clips are
fitted at the toe and sides, the rear clips being formed in a piece with the shoe.
In a jointed shoe as shown in figure 10 I secure in grooves dovetailed or otherwise
formed in the under side of the shoe at the toe and heel or other parts calks A having
formed upon them ribs, clips or flanges a which when the calks are in place project
outwards and are bent upwards over the edge of the shoe and over the hoof and by
gripping the hoof serve to retain the shoe thereon after it has been fitted. The calks Å
may be of any suitable dimensions or shape. The jointed shoe is clasped and securely
bound upon the hoof by a band, strap or bolt B and screw nut or other locking
device passing behind or through the heel part as in my former Specification above
alluded to. The calks may also have a flange on the inside to bend up over the shoe
to afford additional security. In order to lessen the cost of production, I prefer to
employ a solid or non-jointed shoe either plain or with solid calks moulded, forged or
cast thereon or having removable calks with clips or ribs adapted thereto in the manner
already set forth with reference to figure 10 of the drawings. The ribs clips or
flanges a may as indicated in figures 4 to 12 be forged on, drawn out cast, moulded.
or otherwise formed in a piece with the shoe or as shown in figures 1, 2 and 3 made
separate and passed through holes or slots d therein and bent up over the hoof to
secure the shoe permanently to the foot or they may be made removable in accordance
with my former Patent in order to admit the hoof and permit of the shoe being taken
off the foot and replaced at pleasure and with or without base pieces passing through

page_text: holes, slots or dovetailed or other form of grooves in the shoe and secured on one or
both sides of the shoe by screws, bolts, split pins cotters, wedges or other devices
passing through the shoe to retain the ribs or flanges in position in the shoe and
bearing against the hoof. Or the clips may be fitted in vertical grooves in the side of
the shoe and retained by screws or like means as indicated at figure 6 A.
In practise I find it convenient to form the ribs clips or flanges a at the front and
sides in a piece with the shoe and fit one or both of the rear ribs clips or flanges al so
that it may be readily removed, and I secure the said removable rib or ribs in any of a
variety of different ways as for example by a cotter pine serving to retain in place
a base piece formed on the clip, rib or flange and passing through a slot in the shoe
either behind or in front of the base piece of the clip rib or flange as shown at
figures 1 to
or by screws as indicated at figures 6 and 7; or I may make the rear
ribs in a piece with the shoe and provide removable ribs at the toe and sides as shown
at figure 12; or as shown at figure 11 the bases of the ribs clips or flanges a passing
through slots in the shoe may be therein retained and drawn forward, so that the ribs,
clips or flanges bear tightly on the hoof, by means of a U or Y shaped piece F, whose
ends are entered into the slots in the shoe and which is drawn up at its central part or
in front by means of a screw holt passing through the fore part of the shoe.
The removable rear ribs, clips or flanges a' on both jointed or solid non-jointed
shoe, (which as abovementioned may be applied either on both sides of the hoof or at
the outside only) are or may be of curved or arched form extending forward and
having a bearing along the wall of the hoof as indicated throughout the drawings so
that while having a secure grip it may not unduly press on or injure the foot. For a
like purpose the ribs clips or flanges are or may be lined with a cushioning of leather,
cloth rubber or other suitable material and a pad or cushioning may also be placed
between the shoe and the hoof. The hind ribs clips or flanges may be bound together
at the top by a leather or metal strap bolt and screw or other locking device
passing over the hind part of the foot below the fetlock in the manner indicated at
figures 4 and 5.
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. A horse shoe constructed substantially as hereinbefore described under several
modifications and with reference to the annexed drawings.
2. A horse shoe fitted with removable ribs clips or Hanges adapted to secure the
shoe to the hoof without the use of nails substantially as described.
3. A horse shoe formed with fixed ribs clips or flanges and a removable rib or ribs
clips or flanges whereby the shoe may be secured on and removed from the hoof
substantially as described.
4. In a horse shoe adapted to be secured to the hoof without the use of nails a
combined removable calk and rib, clip or flange formed and fitted substantially as
hereinbefore described.
