WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN HORSE-SHOES."
A com-
munication.
The first part of my Invention relates to a novel manner of fastening, in openings
or mortices formed at the heel and toe of a horse-shoe, the calks, the same being
provided with tenon or other suitable bearings designed to enter and fill said
openings or mortices, and they are fastened therein by means of angular grooves or
slots cut in the tenons, which are designed to receive fastening staples constructed
of some suitable metal, the slots owing to their form forcing the shanks of the staple
when driven in so out of the line of their entrance as to cause them to provide a
wedge-shaped bearing, which secures the tenon of the calk rigidly in position in the
mortice or opening.
The second part of my Invention relates to a novel form of calk, or more par-
ticularly the toe calk, and more especially the form of bearings by which it is
connected and rigidly secured to the shoe. The horse-shoe is of the ordinary form,
and of any suitable material. The said shoe is formed with openings or mortices,
two at the heel and one in front at the centre or toe.
The calks are constructed of steel or other suitable material. These calks may
be either flat or blunt. The calks are provided with tenons, and their form and
dimensions are regulated entirely to the size and contour of the mortices or
openings, the tenons entering and snugly fitting within the same, and their upper
surface being on a line or flush with the inner face of the shoe. In the tenons of
the calk or in the face of the shoe are cut angular grooves or slots, which are much
deeper at their forward section or at that section which the shanks or prongs of the
staple first enter than at their opposite section when the staples are driven in their
shanks or prongs so spread or diverge from the line of their entrance as to provide
wedge-shaped bearings for the tenons of the calks, and which securely locks them
in the mortices or openings of the shoe. These staples are made of any suitable

page_text: material, pliable metal being preferred. At the heel of the shoe are open slots or
grooves, which lead into the mortices. The toe calk may be attached by a screw,
but, as above stated, the staple fastening is deemed far preferable.";
The great advantages of my Invention are, its simplicity and durability, and the
expeditious manner in which the calks can be detached when broken or unduly
worn, and replaced with fresh ones by any ordinary groom or attendant, and without
the assistance of a blacksmith.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Robert Lake in the Great Seal Patent Office on the 29th June
1876.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN HORSE-SHOES." A commu-
nication to me from abroad by Edwin Lawrence Tevis, of Philadelphia, Pennsylvania,
United States of America.
The first part of my Invention relates to a novel manner of fastening the calks in
openings or mortices formed at the heel and toe of a horse-shoe,-the calks being
provided with tenon or other suitable bearings which are designed to enter and fill
said openings or inortices, and being fastened therein by means of angular grooves
or slots cut in the tenons, and which are designed to receive fastening staples,
that are constructed of some suitable metal, the slots owing to their form forcing
the shanks of the staple when driven in so out of the line of their entrance as to
cause them to provide as it were a wedge-shaped bearing which secures the tenon of
the calk rigidly in position in the mortice or opening.
The second part of this Invention relates entirely to a novel form of calk, par-
ticularly the toe calk, and more especially the form of bearings by which it is con-
nected and rigidly secured to the shoe.
DESCRIPTION OF THE DRAWING.
Figure 1 is a plan of this Invention; Figure 2 is a longitudinal section on the
line x, x, Figure 1.
Figure 3 is a front elevation of the heel calk.
Figure 4 is a vertical section of the toe calk.
Figure 5 shews a modification of the toe calk.
A is the horse-shoe of the ordinary form, and constructed of any suitable material.
The shoe is formed with openings or mortices B, B, two at the heel, and one in
front at the centre or toe. These openings or mortices may be of any desired form
and dimensions. The form respectively for the mortices at the heel and toe shewn
in the Drawing practical experience has demonstrated is admirably suited for the
purpose designed. C, C, are the calks constructed of steel or other suitable material.
These calks may be either flat or blunt. I usually form the heel and toe calks of
the respective form shown, but any other form would equally as well meet the
requirements of my present Invention.
The calks C, C, are provided with tenons D, D, and their form and dimensions
are regulated entirely by the size and contour of the mortices or openings B, B,
(or vice versa), in which they are designed to have their bearings, the tenons
entering and snugly fitting within the same, their upper surface being on a line or
flush of the inner face of the shoe, as clearly shown in Figures 1 and 2. The toe
calk C, in addition to the tenon D, is provided with a projecting face or flange
plate E, which is of the form shown in Figures 2, 4, and 5. The tenon D and
projecting face or flange plate E are relatively so arranged as to provide or leave a
recess or socket bearing D', in which enters and rests the outer wall B¹ of the toe
mortice B. The toe calk C is shown in Figure 4 detached, and in Figures 1 and 2
attached to the shoe A, and all its relative bearings in connection with the shoe are

page_text: clearly shown in the last of these Figures, as they are also in Figure 5, where the
calk is secured by a screw F', instead of the staple F, as in the other Figures, and
which last style of fastening is much preferred. In the tenons D, D, of the calk, or
in the face of the shoe are cut angular or widening grooves or slots d, d, as clearly
shown in Figures 1 and 3, and which are much deeper at their forward
section or at that section which the shanks or prongs of the staple F first enter than
at their opposite section, so that when the staples are driven in their shanks
or prongs so spread or diverge from the line of their entrance as to provide wedge-
shaped bearings for the tenons of the calks, thereby securely locking them in the
mortices or openings B, B, of the shoe. These staples F, F, are made of any suitable
material, some of the softer or pliable metals being preferred. Any ordinary wire
rod of the desired diameter can be advantageously used for the purpose of forming
the same, and any person possessing the least skill will be competent to cut off a
blank of the requisite length, and then bend the same to the desired form. At the
heel of the shoc are open slots or grooves a, a, which lead into the mortices B, B.
The heel calks C, C, being in position their tenons D, D, filling the mortices, the
staples F, F, are inserted in the slots a, a, the outer section of their prongs entering
the front section of the slots or grooves d, d, then with a few slight blows of a
hammer, or with any suitable ordinary pressure the staples are forced in, their
shanks or prongs spreading or conforming to the contour of the slots or grooves d, d,
as clearly shown in Figure 1, and in which condition they provide a most reliable
and durable fastening, and one which no jarring or straining will detach, and yet a
fastening most easily manipulated when occasion renders the same desirable, it
simply requiring the use of any ordinary pincers to effect this object. The toe calk
may be attached by a screw F', as clearly shown in Figure 5, but, as before stated,
the staple fastening F is deemed far preferable. The tenon D of the toe calk C is
inserted in the mortice B, filling the same, the outer wall 13 enters and fills the
socket D. The staple F is then introduced through the opening c in the pro-
jecting face or flange plate E, and its shanks or prongs entering the grooves or
slots b, b, in the face of the shoe are caused to open and spread, and being driven
into the slots or grooves d, d, of the tenon are provided with secure bearings, as
clearly shown in dotted lines, Figure 1.
The great advantages of this Invention are, its simplicity, durability, and the
expeditious manner in which the calks can be detached when broken or unduly
worn, and replaced with fresh ones by any ordinary groom or attendant, and with-
out the assistance of a blacksmith.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same,.I wish it understood
that I claim,
First. A horse-shoe having a calk or calks attached by means of slots or grooves
cut in the tenon of the calk or face of the shoe and a staple fastening or fastenings,
as above described, and for the purpose specified.
Second. A horse-shoe provided with suitable heel calks, a toe mortice, and a toe
calk formed with a tenon and projecting flange plate, the tenon and plate being
relatively so arranged as to furnish a socket bearing for the outer wall of the
mortice, the saine being secured by a suitable fastening, as above described and for
the purpose specified.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Twenty-eighth day of June, in the year of our Lord
One thousand eight hundred and seventy-six
