Empire of Germany.
I EDMUND EDWARDS, of the firm of Edwards and Co. Patent Agents and
Engineers of 35 Southampton Buildings, Chancery Lane, in the County of Middlesex
do hereby declare the nature of the said invention to be as follows
This invention relates to improvements in horse shoe calks or heels and it has for
its object to provide an easy and cheap method of securing the calk in the horse shoe,
a method which does not require skilled hands but may readily be performed by any
blacksmith, coachman, groom, or other person.
Of the many improvements hitherto made in horseshoes, a great part have reference
to moveable calks but such improvements have not hitherto been found to answer
the necessary requirements. This failure is partly to be attributed to the expensive
mode of manufacturing the calks, and partly to their imperfection as regards solidity
and durability. The simplest construction of moveable calks is, still, the screw
calk, which is more particularly used with heavy horses, but its construction scarcely
allows it to be made well by any ordinary blacksmith, accordingly the screw calks
are comparatively expensive and they also are liable to breakage at the screw.
The moveable calks which form the subject of the present invention afford
all the advantages required in such articles, as they are cheap and may readily
be made by any blacksmith. Any coachman, groom, or other person may readily
remove the worn calk and replace it by a new one in the shortest possible time.
The new calk as shewn in the drawing, is of the shape of a high square truncated
pyramid. Near to the upper end of the calk a groove a is formed with a chisel or
other implement in one of its sides Fig. 4. A corresponding groove is made in
the upper surface of the two arms of the horseshoe, at or near the back edge of the
holes into which the calks are to be secured. To secure the calk the groove a in
it is adjusted in line with the groove bof the shoe and a horse nail n is then inserted

preferably wedge shaped as usual, is forced into the groove below the projecting
nose of the calk and the latter is thereby, drawn into the plate of the horse shoe
as far as possible and is there held secured. The projecting ends of the nail are
then bent down and the upper end, at the outer side of the shoe, may preferably
be cut off by cutting nippers, while the lower inner end of the nail, when bent
down serves to hold the nail in place and prevent its being loosened by wear and
tear. It will be readily understood that a calk of this kind may be easily forged and
finished at a trifling expense, by any blacksmith and without skill or the aid of any
particular tools. To remove the calk from the shoe the bent end of the nail n needs
only to be straightened again and the nail withdrawn, the calk may then be easily
removed and replaced by another.
The particular advantages of this improved calk have already been mentioned
above, but it aught to be particularly remarked that calks of this kind may be applied
to horseshoes of any kind and size and of any shape, the utility of the improved calk
and method of fastening the same being alway alike.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1
The mode of securing moveable calks in horseshoes by means of a groove in one
of the side faces of the calk and a corresponding groove on or in the arm of the
horse shoe, a nail forced into said grooves, when in line, serving to firmly hold the
calk in the shoe, substantially as and for the purpose set forth and shewn in
the drawing.
