IMPROVEMENTS IN HORSE SHOES
Year: 1884

page_text: I, ALEXANDER ANDERSON, of the city and county of Edinburgh, Gardener,
do hereby declare the nature of my said Invention for "IMPROVEMENTS IN
HORSE SHOES," to be as follows:-
This Invention, which relates to improvements in horse shoes, has special reference
to a mode of locking or securing movable frost cogs or calks, or movable plates
formed with cogs or calks, to the shoe, or part of the shoe, which is secured to the
horse's hoof.
The cogs or calks are fitted in dovetailed grooves, formed in the lower side of the
shoe, by entering them from one side or edge, in a manner commonly practised, but
according to my Invention they are secured in position by means of a locking piece
fitted in a dovetailed groove at right angles to the cog groove, This locking piece
rests in its groove, above the line of the cog groove while the cog is being put in or
removed, but when the cog is inserted the locking piece is pressed down over the
end of the cog, and a filling piece sprung into the small groove behind the locking
piece to prevent the locking piece rising. Instead of fitting the cogs or calks from
the side they may be fitted into recesses cut in the lower side of the shoe, pressed
laterally into dovetailed grooves and retained there by locking pieces sprung in
behind them.
When cogs or calks are formed on movable plates these plates are cut to the
shape of the shoe and are fitted into dovetailed grooves or grooved recesses formed
between the heel parts and the toe, and are secured in place by locking pieces similar
to those described as applied for locking the movable cogs or calks, or by passing
T headed pins or short bolts through slots cut both in the shoe and movable plate.
and turning the pins or bolts, so that they cannot fall out, and securing them by a
locking piece.

I, ALEXANDER ANDERSON, of the city and county of Edinburgh, Gardener,
do hereby declare the nature of my said Invention for IMPROVEMENTS IN
HORSE SHOES," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This Invention, which relates to improvements in horse shoes has special reference
to a mode of locking or securing movable frost cogs or calks or movable plates
formed with cogs or calks to the shoe or part of the shoe which is secured to the
horse's hoof.
The cogs or calks are fitted in dovetailed grooves, formed in the lower side of the
shoe, by entering them from one side or edge in a manner commonly practised, but
according to my Invention they are secured in position by means of a locking piece
fitted in a dovetailed groove at right angles to the cog groove. This locking piece
rests in its groove above the line of the cog groove while the cog is being put in or
removed, but when the cog is inserted the locking piece is pressed down over the
end of the cog, and a filling piece is sprung into the small groove behind the locking
piece to prevent the locking piece rising. Instead of fitting the cogs or calks from
the side they may be fitted into recesses cut in the lower side of the shoe, pressed
laterally into dovetailed grooves and retained therein by locking pieces sprung in
behind them.
When cogs or calks are formed on movable plates, these plates are cut to the
shape of the shoe, and are fitted into dovetailed grooves or grooved recesses formed
between the heel parts and the toe, and are secured in place by locking pieces similar
to those desired as applied for locking the movable cogs or calks, or by passing
Theaded pins or short bolts through slots cut both in the shoe and movable plate,
and turning the pins. or bolts so that they cannot fall out, and securing them by a
locking piece.
In the accompanying drawings figure 1 is an inverted plan of one modification
of the improved horse shoes, and figure 2 is a corresponding elevation of the same.
Figure 3 is a corresponding elevation of a similar form of shoe. Figure 4 is an
inverted plan and figuro 5 a corresponding elevation of another modification.
Figures 6 and 7 are corresponding views of a further modification, and figures 8
and 9 are views of details.
Figures 1, 2 and 3 illustrate the mode of locking the toe and heel calks C in the
dovetailed groove gin the shoe S. The calks C are passed from the side into the
groove which is formed in the lower side of the shoe a locking piece L fitted in a
dovetailed groove is pressed down over the end of each calk or cog C and a filling
piece is sprung into the end of the groove / behind the locking piece.
In the example shown in figures 4 and 5 the cogs or calks C are dropped into
dovetailed grooves or recesses formed for them in the shoe, pressed laterally into
place and therein secured by sliding locking pieces L which are prevented from
returning by springing or fitting in a filling piece f behind the locking piece or
between each pair of locking pieces.
The arrangement of the locking piece and filling piece is shown particularly in
figure 8. Figures 6 and 7 illustrate one mode of securing to the body of the shoe
a movable plate P formed with toe and heel calks. The plate P is fitted between
dovetailed grooves or notches g at the toe and heel, and it is secured in position
by passing headed pins t through slots cut in both the plate and shoe and then
turning such bolts and retaining them in place by a filling piece f. The shoe alone

page_text: is in each case secured by nails to the horse's hoof. Figure 9 shows the T headed
bolt as fitted to secure the movable plate to the shoe.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare what
I claim is,―
First. The arrangement of the locking piece and filling piece for securing in place
the movable calks or cogs of horse shoes, substantially as herein described and
illustrated.
Second. The combination with a horse shoe of a movable plate secured thereto
in the manner herein described and illustrated.
