PROVISIONAL SPECIFICATION.
Certain Improvements in Frost Cogs or Studs for Horse Shoes.
I, GEORGE HENRY DUDLEY, of Broadfield House, Kingswinford, near
Dudley, Staffordshire, Manufacturer, do hereby declare the nature of this inven-
tion to be as follows:-
This invention consists of the hereindescribed improvements in frost cogs or
studs for horse shoes my invention being directed to so construct the said frost
cogs or studs that they will remain sharp in wear for a much longer time than
heretofore.
A frost cog or stud constructed according to this invention has a chisel shaped
wearing surface strengthened on each side by one or more upwardly directed
projecting ribs which are inclined downwardly towards the chisel edge and extend
right along the cog or stud to the top of the same, the part which fits in the square
rectangular or oblong hole in the horse shoe being parallel or made very slightly
taper for driving into the shoe.
It will be seen that my improved frost cogs or studs made as above described
may be of various shapes in cross section at the upper part which fits in the shoe,
such for instance as cross shape, angle shape, tee shape, H shape, channel shape or
of a compound H section, that is with three or more projecting ribs at each side,
or I may use a compound channel section which has three or more projecting ribs
on one side only. The advantage of making the frost cogs or studs of the
sections above described is that the chisel part being strengthened by the side ribs
may be made much thinner than heretofore and therefore will as it wears maintain
a much sharper surface than do those studs or cogs of the usual chisel sbape.
My improved frost cogs or studs above described are by preference made
from rolled steel bars of corresponding cross, tee, angle, H, or other section.
The ribs or some of the ribs of the frost cogs or studs are by preference
shouldered down where they fit in the horse shoe so as to facilitate the extraction
of the frost cogs or studs by driving a chisel shaped tool in between the shoulders
and the shoe.

COMPLETE SPECIFICATION.
Certain Improvements in Frost Cogs or Studs for Horse Shoes.
I, George Henry Dudley, of Broadfield House, Kingswinford, near Dudley,
Staffordshire, Manufacturer, 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 :-
This invention consists of the hereindescribed improvements in frost cogs or studs
for horse shoes my invention being directed to so construct the said frost cogs
or studs that they will remain sharp in wear for a much longer time than

page_text: A frost cog or stud constructed according to this invention has a chisel shaped
wearing surface strengthened on each side by one or more upwardly directed
projecting ribs which are inclined downwardly towards the chisel edge and extend
right along the cog or stud to the top of the same the part which fits in the hole in
the horseshoe being parallel or made very slightly taper for driving into the shoe.
On the accompanying drawing Figs. 1, 2, 3, 4 and 5 are respectively general
views of five different forms of frost cogs or studs made according to this invention;
and Figs. 6, 7, 8, 9, 10 and 11 shew how the frost cog made with a cross section
sbank as Fig. 1 will fit in holes of various shapes in the shoes.
The same letters of reference indicate the same or corresponding parts in all the
figures.
By an examination of the drawings it will be seen that a is the chisel shaped
wearing part of the frost cog or stud which is continued to the top band is
strengthened at one or both sides by one or more upwardly projecting ribs o'c³c² c
which are inclined downwardly at towards the chisel edge and extend right along
the cog or stud to the top 6 of the same. The upper parts of the ribs and of the
chisel shaped part forming the shank which fits in the hole d in the horseshoe are
as in other cogs or studs made parallel or very slightly taper for driving into the
said hole in the shoe.
It will be seen that my improved frost cogs or studs made as above described,
may be made of various shapes in cross section at the upper part which fits into
the shoe. For instance as shewn by Fig. 1 the frost cog or stud may be of cross
sbape in cross section; or as shewn in Fig. 2 the cross section inay bé angle
shape or T shape (Figs. 3 and 4); or as shewn by Fig. 5 of a compound
H-section which has two ribs marked respectively c¹ c³ projecting on one side of the
same and two ribs cc projecting on the other side thereof.
The advantage of making the frost cogs or studs of the sections above described
is that the chisel part a being strengthened by the side ribs c¹³ ³ c², or one or
more of them as shewn, may be made much thinner than heretofore and therefore
will, as it wears, maintain a much sharper surface than do those cogs or studs of
the usual chisel shape.
My improved frost cogs or studs above described and shewn are by preference
made from rolled steel bars of corresponding shape in cross section, that is to say,
the frost cogs shewn by Fig. 1 will be made from rolled bars of cross shape; those
shewn by Fig. 2 from rolled bars of angle section; those shewn by Figs. 3 and 4
from rolled bars of T-section; and those shewn by Fig. 5 from rolled bars of the
combined H-section. The ribs or some of the ribs, of the frost cogs or studs made
of the sections above described; are by preference shouldered down at e to
facilitate the extraction of the frost cogs or studs by driving one of the well known
chisel shaped extracting tools in between the shoulders and shoe.
When the frost cogs or studs are made of the square section shewn in Fig. 1
they will fit in holes of various shapes in the horse shoes; for instance as shewn in
Figs. 6 and 7 they will fit into a square hole; or an octagonal hole as shewn in
Fig. 8; or in hexagonal holes as shewn in Figs. 9 and 11; or in a round hole as
shewn in Fig. 10.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. Making frost cogs or studs for horse-shoes of the improved chisel shape
strengthened by one or more side ribs so arranged as to form the stud or cog of
any of the various cross sections substantially as described and shewn.
2. The hereindescribed improved frost cog or stud for horse shoes made with
chisel shaped wearing part a shouldered at ee and strengthened by the two side
ribs c¹³ inclined at towards the chisel edge, substantially as shewn by Fig. 1 of
the accompanying drawing.
3. The hereindescribed improved angle section frost cog or stud for horse shoes

page_text: made with chisel shaped wearing part a strengthened by the inclined side rib c¹
formed therewith the said rib and chisel shaped part a being shouldered at e, all
substantially as described and shewn by Fig. 2 of the accompanying drawing.
4. The hereindescribed improved T-section frost cog or stud for horse shoes
made with chisel shaped wearing part a strengthened by the inclined side ribs c'c²
and shouldered at ee all substantially as described and shewn by Fig. 3 of the
accompanying drawing.
5. The hereindescribed improved T-section frost cog or stud made with chisel
shaped wearing part a strengthened by the inclined side rib c¹ and shouldered
at ee all substantially as described and shewn by Fig. 4 of the accompanying
drawing.
6. The hereindescribed improved compound H-section frost cog or stud for
horse shoes made with chisel shaped wearing part a strengthened by four inclined
side ribs c¹³ and shouldered at e e, all substantially as described and shewn
by Fig. 5 of the accompanying drawing.
