5 Claims.
The present invention relates to a method of
manufacturing exchangeable calks for horse
shoes comp-rising Wedges and holders therefor,
where the horse-shoes are provided with substan
5 tially rectangular holes, in each of which two
holding members are applied, between which a
wedge member is to be driven in.
'
The invention has for its object to facilitate
' by simple working operations a rational, cheap
10 and simple manufacturing of the above men
tioned members While maintaining a great ac
curacy.
The invention consists essentially in this that
the wedges and the holding members are punched
15 out from a double pro?le-material, in such a
manner that the wedges obtain at least two ?ex

.
A ?rst step may consist in punching a trans
verse hole 3 in the web 4 of the pro?le-material
i 'of the shape shownin Fig. 2. Then the punch~
ing of the H-shaped slot 5 in the web is performed,
and simultaneously depressions 6 may be formed
in proximity to the swelled tread portion 1, so
that there is formed a projection 8 at the oppo
site side of the web, said projection serving as a 10
guide at the driving ‘in of the wedge member 2
between the holding members, as will be more
clearly described below. Then a cutting or shear
ing is performed along the longitudinal central
line Z and also along the transverse central lines 15

out, in the web‘ of the double pro?le-material,
The manufacture of wedge members to be used
in winter time according to Figs. 4 to 6 is per 25
holes or apertures having a substantially rec
tangular shape with the length direction sub
stantially parallel with the transverse direction
of the pro?le-material and also apertures having
substantially an H-shape with the ‘staffs lying
30 substantially parallel to the said transverse di
rection and at a distance from the rectangular
apertures and then cuttings or shearings are made
longitudinally and transversely with respect to
the pro?le-material, so that wedges are formed,
35 each comprising a tread portion, a wedge-shaped
portion to be driven in into the horse-shoe, and
?exible ?aps projecting from said latter portion.
The invention is illustrated in the annexed
drawing. Fig. 1 is a cross—sectional view of the
pro?le-material for wedge members to be used
in summer time, and Fig. 2 a plan view thereof.
Fig. 3 is an end View of a ?nished wedge member.
Figs. 4, 5 and 6 are similar‘ views of a pro?le-ma
terial and a wedge member to be used in winter
45 time. Fig. '7 is a cross-sectional view of the pro
?le-material for the holding members, and Fig.
8 is a plan view thereof. Fig. 9 is a side view and
Fig. 10 an end view of a ?nished holding mem
ber. Fig. 11 shows a portion of a horse-shoe
50 partly in section having holding members and
a wedge member applied.
The punching iscperformed in an ordinary
stamping machine by means of suitable punches
having a ?guration according to the above men

the same manner as described above, however
with the difference that wedge or triangularlye
shaped slots l5 are punched out at the edges of
the pro?le-iron I for instance simultaneously 30
with the punching of the apertures 5. The dif~
ference as to the ?nished wedge member 2 con
sists, besides, in this only that the tread portion
‘I is here wedge-shaped in order to be more suit‘
able for use in winter time.
As apparent from Fig. 4, each half of the pro—
?le-iron shows in ‘cross-section the shape of two
wedges having the bases turned towards each
other, the symmetry lines of said wedges forming
an angle with each other, as shown by the dashed 40

the horse-shoe in a suitable manner tread in
juries may by such means be avoided and, besides,
the wedge can be applied to suit different walks

of horses.
The wedge-shaped tread portion may be pro
vided at the one side or, as shown, at both sides
with swelled portions 1 8, which indicate, when
the wedge has been worn out to such an. extent
that an exchange is to be made. The swelled 50
portions also facilitate the tempering of the
wedges, inasmuch as they may form a stop at
the immersing of the wedges into the tempering
liquid and, besides, due to the accumulation of
material separate the tread portion 1 adapted to

By a pressing operation projections [3 are at
?rst formed at the longitudinal edges of the pro

out adjacent to the said projections and simul
taneously depressions l2 may be made at the cen

adapted to serve as a guiding slot for the projec~
tion 8 of the wedge member 2 at the driving in
thereof between the holding members I I. Finally
cutting or shearing is performed along the dashed
and dotted lines, Fig. 8, and two holding members
will be produced at a time. By such a method
the pro?le-material will be very economically
utilized, since the central rib I‘! only will remain

As apparent from Figs. 1, 4 and 7 the web

shape of two truncated wedge-shaped parts di

parts are joined by a rectangular or square part

shaped parts may lie in the same plane, so that
the punches can obtain a plane working surface.
