J. O. NYGAARDYET AL HORSESHOE GALK BAR Original-Filed Dec. 17, 1955 Patented Jan. 24, 1939 UNITED STATES PATENT OFFICE Miiien, Stockholm, Sweden, bolaget Nordiska Hovbeslaget,
Sweden assignors to Aktie- Stockholm,
Original application December 17, 1935, Serial No.
54,916, now Patent No. 2,117,817,
dated May 17,
1938. Divided and this application September 26, 1936, Serial No. 102,804. In Germany February 12, 1934 4 Claims.
The present invention relates to double profile material to be used in the manufacture of wedge members and holding members therefor for exchangeable calks for horseshoes by punching and shearing operations, the present application being a division of our pending application Serial No. 54,916, filed December 1'1, 1935.
The invention is illustrated in the annexed drawing. Fig. 1 is a cross-sectional view of the profile-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 finished wedge member. Figs. 4, 5 and 6 are similar views of a profile-material and a wedge member to be used in winter time. Fig. 7 is a cross-sectional view of the profile-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 finished holding member. Fig. 11 shows a portion of a horseshoe partly in section having holding members and a wedge member applied.
The punching is performed in an ordinary stamping machine by means of suitable punches.
A first step may consist in punching a transverse hole 3 in the web 4 of the profile-material of the shape shown in Fig. 2. Then the punching 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 opposite side of the web, said projection serving as a 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 shearing is performed along the longitudinal central line I and also along the transverse central lines 11 and 12 of two adjacent holes 3, two wedge members having flexible flaps 9, a tread portion 1 and the projection 8 being thus produced at a time.
The manufacture of wedge members to be used in winter time according to Figs. 4 to 6 is performed by punching, depressing and shearing in the same manner as described above, however with the diiference that wedge or triangularly-shaped slots 15 are punched out at the edges of the profile-iron l for instance simultaneously with the punching of the apertures 5. The difierence as to the finished wedge member 2 consists, besides, in this only that the tread portion 1 is here wedge-shaped in order to be more suitable for use in winter time.
As apparent from Fig. 4, each half of the profile-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 and dotted lines. By inserting the wedges in the horseshoe in a suitable manner tread injuries may by such means be avoided and, be-
sides, the wedge can be applied to suit different walks of horses.
The wedge-shaped tread portion may be provided at the one side or, as shown, at both sides with swelled portions l8, which indicate, when the wedge has been worn out to such an extent that an exchange is to be made. The swelled portions also facilitate the tempering of the wedges, in as much 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 be tempered to a higher degree from the relatively soft portion adapted to be driven in between the holding members and the flaps of which have to be flexible.
The manufacturing of the holding members H according .to Figs. '7 to. 10 may for instance be performed in the following manner.
By a pressing operation projections l3 are at first formed at the longitudinal edges of the profile-material l0, and then recesses M are stamped out adjacent to the said projections and simultaneously depressions I2 may be made at the central part of the material, said depressions being adapted to serve as a guiding slot for the projection 8 of the wedge member 2 at the driving in thereof between the holding members (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 profile-material will be very economically utilized, since the central rib ll only will remain as wastrel.
At the applying of two holding members against each other the projection I3 of the one member will correspond to the recess M of the other and vice versa, so that after the inserting of the holding members into the horseshoe and at the driving in of the wedge member, Fig. 11, the projections l3 will bend the flaps 9 of the wedge member in opposite directions, whereby the flaps enter the recesses I.
As apparent from Figs. 1, 4 and '7 the web of the profile-material has in cross-section the shape of two truncated wedge-shaped parts directing the apices towards each other, which parts are joined by a rectangular or square part l6, whereby two equilocated sides of the wedgeshaped parts may lie in the same plane, so that the punches can obtain a plane working surface.
What we claim as new and desire to secure by Letters Patent of the United States of America is:-
1. A double profile-material to be used in the manufacture of wedge members and holding members therefor for exchangeable calks for horseshoes by punching and shearing operations, wherein the web of said profile-material has the shape of two truncated wedges having the apices directed towards each other and joined by a part having a transverse rectangular cross-sectional configuration.
2. A double profile-material to be used in the manufacture of wedge members and holding members therefor for exchangeable calks for horseshoes by punching and shearing operations, wherein the web of said profile-material has the shape of two truncated wedges having the apices directed towards each other and joined by a part having a transverse rectangular cross-sectional configuration, two symmetrically disposed sides of said wedges lying in the same plane.
3. A double profile-material to be used in the manufacture of wedge members and holding members therefor for exchangeable calks for horseshoes by punching and shearing operations, wherein the web of said profile-material has the shape of two truncated wedges having the apices directed towards each other and joined by a part having a transverse rectangular crosssectional configuration, each half of said double profile-material having in cross-section the shape of two wedges having the base ends directed towards each other, the axial lines of said wedges forming an angle with each other.
4. A double profile-material to be used in the manufacture of wedge members and holding members therefor for exchangeable calks for horseshoes by punching and shearing operations, wherein the web of said profile-material has the shape of two truncated wedges having the apices directed towards each other and joined by a part having a transverse rectangular cross-sectional configuration, each half of said double profile-material having in cross-section the shape of two wedges having the base ends directed towards each other, one of said wedges constituting a tread member, the axial lines of said wedges forming an angle with each other, and a swelled portion formed on at least one side of said base end of the tread member.
