PROVISIONAL SPECIFICATION.
Improvements in Horse-shoes.
I CHARLES LEA of Church Street Silverdale in the County of Stafford Tailor,
do hereby declare the nature of this invention to be as follows:-
My present invention relates to horse shoes and the object thereof is to
construct said horse shoes in such a manner that they may be easily and expeditiously
repaired from time to time as required without it being necessary to remove the shoe
plate or greater portion of the shoe from the horses foot for this purpose therefore
I manufacture a plate of malleable iron steel or other suitable metal or material in
the ordinary horse shoe shape having the usual countersinking at each side thereof
for the reception of the heads of the nails used for securing the plate to the foot
of the horse.
At the toe end or fore part of the said plate arrange or form crosswise thereof
a dovetail groove or recess which is tapered or of a wedge shape longitudinally
that is to say the said groove or recess is wider upon or at one side or edge of the
plate than on the opposite side or edge.
Into the dovetail groove or recess I fit the upper portion of a specially made bar
wedge or cotter the said upper portion of which corresponds in cross section to the
form of the groove or recess formed across the plate and it is also correspondingly
tapered so as to fit perfectly tight after being hammered or otherwise driven or
forced therein.
The said groove or recess may be of any suitable form in cross section other than
dovetail for instance it may have an undercut at each upperside thereof or more
than one undercut upon each side may be arranged and in each case the upper part
of the bar wedge or cotter corresponds in cross section to the form of the said
groove and is also made similarly tapered longitudinally in order that it may be
firmly and securely driven therein.
When desirable two wedges or bars may be employed and the dovetail or other
groove or recess aforesaid is tapered from each outside edge of the plate towards
the centre. The bar wedge or cotter may have made with or secured to its narrow
end a projecting piece of iron or other metal which can be hammered or pressed
over after the said wedge has been driven into the recess in order to lock or better
secure the said wedge to the plate.
Each bar wedge or cotter may be made with an oblong projection upon its under-
side or the said projection may be in the form of a beading or it may be sharpened
or pointed and more than one projection may be so made upon the under part of
the said wedge or cotter.
At each back part or portion of the shoe plate aforesaid I also form a dovetail
or other groove or recess which may be in cross section of any of the forms herein-
before described with reference to the groove or recess arranged at the fore part of
the plate and each recess so formed at the back part of the horse shoe plate extends
and is tapered from the outer edge to the inner edge thereof across the said plate.
I employ a separate wedge or bar to fit in each of these grooves or recesses the
undersides of which are made with projections either in the form of frost spikes or
in any other convenient manner.

The shoe plate L has a groove formed at the toe part thereof wherein fits the
attachable toc piece bar wedge or cotter M having formed thereon a projecting tail
piece m which is hammered or otherwise compressed into a recess formed in the
shoe plate for its reception by this means the said toe piece or bar M is firmly
held in position and secured to the shoe plate I. The groove may be of a
dovetail form in cross section as shown at Fig. 2 or it may be made in the
undercut form similar to that shown at Figs. 5 7 and 9. The said groove
of a wedge shape or tapered but where desirable it may be made parallel in
order to receive an attachable toe piece or bar M such as shown at Figs. 19
and 20 in which latter case each end of the said attachable toe piece or bar M
is formed with a tail or projecting piece m' and the said groove is formed
with a recess at either end thereof so that when the toe piece or bar M is
fitted into the groove each projecting tail piece m' is hammered or pressed
over or down into the said recess thus securely holding the toe piece or bar M
to the shoe plate L as will be well understood. The calks or attachable heel
or side pieces or bars N are made with flanges n¹ in order to fit in the undercut
grooves made in the shoe plate L for their reception and each said attachable
piece N has a tail or projecting piece which is hammered or pressed into the
recess after the said attachable piece or bar N has been driven into the groove 1³.
The said grooves for the reception of the calks attachable pieces or bars N are
shown of a wedge shape or tapered at Figs. 10 to 18 but it will be obvious that
where desirable the same may be made parallel and the grooves for their reception
into the plate L may in like manner be parallel in which case each calk or attachable
piece or bar N is formed with two tail or projecting pieces n' and each undercut
groove is made with a recess at either end thereof so that when the said calk or
bar N is placed in the undercut groove the said projecting tail pieces n² are
hammered bent or pressed down into the recesses and thereby the said calks are
firmly and securely fixed to the shoe plate L.
Referring to Figs. 23 to 27. The plate L is made with an undercut parallel groove /
and in order to secure the toe piece or bar M it has a projecting tail piece m³ formed
or arranged at the centre part thereof and when the said toe piece or bar M is fitted
into the groove I hammer or press down the said projecting tail piece m³ into the
recess formed in this case in the face of the plate L as shown.
Referring to Figs. 28 to 30 the toe piece M is secured to the shoe plate L by being
first pressed into the hole or groove and then the tail piece m³ is hammered into
the recess and in this arrangement the calks or heel pieces N are pressed into the
holes or grooves 3 and the tail pieces n² are hammered into the recesses. Where
desired the recesses need not be formed but in this case it is essential to bevel the
inner part of the shoe in the manner shown so that the tail pieces m¹ and n² will
effectually lock or secure the toe piece M and calks N from falling away from the
shoe L.
Referring to Figs. 31 to 33. The tail pieces m' and n³ are spread out in the
manner shown and after the toe pieces M and calks N have been placed in position
within the grooves or countersunk parts and suitable screws E are employed in
order to secure the said tail pieces m³ and n² to the shoe plate L.
In Fig. 34 the calks N and toe piece M are made without the tail pieces and
screws E are employed for keeping the said toe pieces M and calks N in position.

page_text: Similarly the undercut grooves for the reception of the attachable calks bars or
heel pieces may be made parallel to correspond with said bars N and the
recesses for the reception of the projecting tail pieces al may be arranged on the
face of the shoe plate as shown.
Each attachable calk heel piece or bar N has one or more projecting tail pieces al
which extend in a vertical direction when the said ealks or bars N are detached
from the shoe plate L as shown at Fig. 27 but when the said calks or bars N are
fitted into their respective grooves the said projecting tail portions are hammered
down to horizontal position and fit well into the recesses as shown at. Fig. 25.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed | declare that what I
claim is
1. A horse shoe composed of a plate L having a groove and a recess or
recesses and an attachable bar wedge cotter or toe piece M, having a projecting
tail piece or pieces m² substantially as described.
2. A horse shoe composed of a plate L made with underent grooves and
recesses and attachable heel pieces calks or bars N having tail pieces n' arranged
substantially as described.
3. Horse shoes arranged and constructed in any of the ways described and
illustrated in the accompanying drawings.
