Improvements in Roughing or Means Applicable to Horse Shoes
for Preventing Slipping.
We, JOHN LETHBRIDGE of No. 1 St. Georges Terrace, Lower Edmonton, in the
County of Middlesex, Smith and Farrier, and RAPHAEL CLAUDIUS ROMANEL of No. 1
Dunning Terrace, Derby Road, Ponders End, in the County of Middlesex, Engineer,
do hereby declare the nature of this invention to be as follows :-
Various means have been employed for the purpose of roughing horses to prevent
their slipping in frosty weather or when the ground is covered with snow.
In some cases screws having pyramidal or spike-like heads have been screwed into
the shoes themselves but this plan is open to objection because when the screws are
removed the holes made to receive them become filled and thus it is difficult to replace
the screws when required for use.
Now this invention has reference to means whereby, without making any special
holes in the shoes, a horse may be readily roughed when required and the roughing
can be readily removed when not required for use, thus obviating risks of accident to
horses in the stable.
For this purpose, according to this invention suitable projections are formed or fixed
upon a cross-bar and upon a piece that can be readily applied to the front part of the
shoe at the inner sido, these parts being then secured in place by means of a screwed rod
that acts as a strut or locking piece, forcing the front piece already mentioned forward
and the cross-bar rearward. The arrangement is such as to clear the horse's foot when
the appliance is in place.
The cross-bar is recessed at its ends and bears against and partly embraces the inner
edges of the shoe near the heel.
The projections forming the roughing on this bar may be pyramidal or spike-like
heads of screws such as before referred to, which are screwed into the bar itself.
Similar screws may be used with the part of the device that is applied to the inner
front portion of the shoe or that part of the device may be formed with a projection
resembling a flange or blunt blade.
The arrangement is such as to allow for expansion of the shoe.
The screwed rod or locking piece may have a square part or be equivalently formed
to receive a key, spanner or tommy for tightening the parts in place or releasing them.
Dated this 17th day of December 1888.

Improvements in Roughing or Means Applicable to Horse Shoes
for Preventing Slipping.
Wo, JOHN LETHBRIDGE, of No. 1 St. Georges Terrace, Lower Edmonton, in the
County of Middlesex, Smith and Farrier, and RAPHAEL CLAUDIUS ROMANEL, of No. 1,
Dunning Terrace, Derby Road, Ponders End, in the County of Middlesex, Engineer,
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 :-
Various means have been employed for the purpose of roughing horses to prevent
their slipping in frosty weather or when the ground is covered with snow.
In some cases screws having pyramidal or spike-like heads have been screwed into

page_text: the shoes themselves but this plan is open to objection because when the screws are
removed the holes made to receive them become filled and thus it is difficult to replace
the screws when required for use. Not only so, but the holes get burred up, and with
the constant wear on the shoe it becomes at the parts where the holes occur too thin
to afford an efficient hold for the screws, thus rendering it impracticable to apply the
roughs when suddenly required. A further objection to the old plan above referred
to is that should the pyramidal or other head break off leaving the screw in the shoe
the latter has to be taken off to enable the screw to bo withdrawn after which the shoe
has to be re-fixed.
It has also been proposed to use a removable roughing device comprising a screw
with a peculiarly shaped head having a lateral wedge shaped projection to bear on the
road and a recess to receive a part of the fore portion of the shoe and a cross bar with
two wedge shaped projections to bear on the road and a large hole in which the end
of the bolt could enter freely the arrangement being tightened in place on the shoe
by nuts on the bolt.
This construction however is open to the objection that when the wedge shaped
projection on the head is much worn or broken the screw will become useless, and
must be replaced by a new one. Again, with this construction it is not practicable to
place the front projection to one side of the centre line of the shoe as is sometimes
desirable in order to prevent its coming under a tender part of the animal's foot.
Now this invention has reference to improvements in the construction of a roughing
device of the well-known kind last referred to, whereby the disadvantages mentioned
are obviated.
For this purpose in lieu of employing a screw with a peculiarly formed head such
as above referred to a separate part is so constructed as to adapt it to fit over the inner
edge and the under surface or solo of a part of the front of the shoe and to receive one
end of a strut or locking piece formed with a screw thread. The screw part of this
strut screws into a hole formed with a corresponding female screw thread in the cross
bar which is recessed at its ends and bears against and partly embraces the inner edges
of the shoe near the heel and overlaps parts of tho under surface or sole of the shoe.
The projections forming the roughing on this bar may be pyramidal or spike-like
heads of screws such as before referred to, which are screwed into the bar itself.
Similar screws may be used with the part of the device that is applied to the front
portion of the shoe or that part of the device may be formed with a projection
resembling a flange or blunt blade. The arrangement is such as to allow for expansion
of the shoe. The strut or locking piece has a square part or is otherwise suitably
formed to receive a key spanner or tommy for tightening the parts in place or
releasing them.
Referring to the accompanying sheet of illustrative drawings
Fig. 1 represents in inverted plan a shoe fitted with a roughing device (hereinafter
called a rough) according to this invention.
Fig. 2 is an end elevation of the rough detached, and
Fig. 3 a central longitudinal section thereof on the line A. B. of Fig. 1, but with
the strut in elevation.
a represents a cross bar, through the centre of which is formed a hole with a
female screw thread; b is a strut or locking piece the part 1 of which is a male
screw adapted to engage with the above mentioned female scrow. The ends of the
cross bar a are recessed to receive and bear against parts of the inner edge of
the shoe, near the heel, as shewn in Fig. 1. c is a piece of metal suitably formed
and recessed as shewn to adapt it to receive and bear against the inner edge of a
front part of the shoe and having projections d d such as shewn or projections of
other suitable form adapted to afford a good foothold as well understood.
The strut or locking piece b which, as already stated, is, according to this
invention made separate from the cross bar a and piece c has formed upon it a
square or other conveniently shaped part f, or a hole or holes through it to receive
a key or tommy, or is otherwise suitably adapted to be turned as required to force
the parts a and c apart, and against the inner edge of the shoe where they are

page_text: respectively intended to bear, thereby securing the several parts of the appliance in
position for use.
On or near the recessed parts a' of the cross bar a are fixed (either by screwing
or otherwise) projections e'e of pyramidal or spike-like form that enable a firm
grip to be obtained upen a frosty or slippery road. The projections employed
for this purpose may be of any suitable form.
When it is required to remove the rough, the strut or locking piece is turned back
until it is clear of the front piece c, when it can be removed from the shoe ; then, the
distance between the inner edges of the shoe being greater near the centre of its
length, the cross bar a can be moved forward so that its ends will clear the shoe.
With the construction described, the front piece c may, if desired, be secured in
place to one side of the axis of the strut or locking piece b as indicated by dotted lines
in Fig. 1, in order to avoid its being placed directly under a tender part of a
horse's hoof.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what wo
claim is :-
1. A horse shoe rough of the kind referred to in which the part adapted to be
applied to the fore part of the shoe is made separate from and is secured in place by a
strut or locking piece such as described.
2. The improved horse shoe rough as described and shown.
