The present invention relates to a device for cold deformation of horseshoes for horses so as to adjust it to the foot of the animal. The invention is intended for different ranges, sizes and widths of steel and other materials. The horse shoe has two branches divided into zones; in front of the pliers, then in order the two udders, the two quarters and the two sponges; these are not necessarily symmetrical with respect to the clamp. The internal and external edges of the iron are called respectively internal and external edges. The front of the shoe can have one or two projections called clips.

The deformation of a horseshoe will be defined as follows: opening or closing of the clamp, udder, quarter and sponge parts.

For steel irons, these deformations are traditionally carried out hot by heating the iron red in a gas or coal forge. The deformation of the red-hot iron requires hitting it to deform it, which requires efforts that cause muscle and joint fatigue.

The strike on the red iron causes splashes of hot carbon, which could burn the face and eyes. This passage to the forge consumes gas therefore energy. The introduction or taking of iron in the forge always represents a danger of burns.

These deformations can be carried out by cold striking, which requires hitting the steel hard, which requires more effort and therefore more muscle and joint fatigue. In this case the iron is less well deformed therefore more difficult to adjust.

These cold or hot distortions generate a lot of noise, which can cause hearing problems.

The smoke from putting hot iron on the horn can cause a respiratory gene.

The present invention aims to remedy these drawbacks and to overcome the drawbacks of the prior art by proposing a cold deformation device that meets these constraints and by providing an evolution compared to the systems already proposed.

It comprises a fixed frame supporting a fixed stepped central cam, a stud with facets comprising an additional thickness, articulated on the frame and a lever articulated at the level of the central cam; this lever also carries two studs with facets hinged thereon. The length of the lever and the position of the two studs relative to the articulation of the lever are such that the force exerted by the user at the end of the lever is multiplied and allows

-2 therefore to deform the iron. So when the horseshoe rests on the one hand on the facet block of the frame and on the central cam, the user by pressing the lever exerts pressure on the branch of the iron via the facet block articulated on it. This lever is provided with two faceted studs making it possible to bend different parts of the iron. The effort of the user can be amplified using a jack or an electric motor or the like.

- The section of the stud is hexagonal, so six facets, but the number of facets can be lower or higher.

- The faceted studs are all mounted on an eccentric for easy adjustment in relation to the different ranges, sizes and widths of iron (iron cover), curvatures and different desired deformations of the iron.

- The value of the eccentric can also be different.

- The faceted studs are spring-braked to keep their position and allow them to be adjusted in rotation.

- The length of the studs is such that it allows the irons to be clamped forwards or clamps behind to bend one branch of the iron or the other.

- The facet block of the frame has an extra thickness on a facet so as to adapt to small iron sizes and their thickness for plumbing.

- The central cam is profiled without sharp angles for correct support of the iron.

- The central cam has a stepped part allowing the use of two offset surfaces. The contact of the iron will be in the lower part or in the upper part depending on the case of desired deformation and according to the size of the iron.

- Cleats integrated on the one hand to the frame, on the other hand to the lever allow to close or open the iron and the branches of the iron.

- The cleats are eight in number and can be notched to prevent slipping of the iron.

- The lever being located in a plane, the faceted studs will be located in front of this plane and the cleats behind this plane.

Two cleats allow to close the branches of the iron by its end.

Two tabs close an area of the iron by contact on the edges external to the branches.

Two cleats open the branches of the iron at its end. Two tabs open an area by contact on the internal edges of the branches.

-3The device can be fixed on a positionable base, on an anvil, on a fixed support or independent support. The angle of inclination is adaptable so as to exert the force on the lever in an ergonomic and effective position for the user.

The device is used by placing the iron flat, either in front of the plane of the lever, or behind it according to the desired deformation.

Support surfaces allow the iron to be positioned in the plane of the deformations.

The device is also used by placing the iron perpendicular to the lever to balance the iron.

The device is used by turning the studs so as to bring the eccentric facet best suited to the size or range of the iron and the desired amount of deformation.

With reference to these drawings, in the case of FIGS. 1, 2, 3, the device comprises a fixed frame (1) supporting a fixed central cam (IC), a faceted stud (3) articulated on the frame (1) and a lever (2) articulated at the level of the central cam (1C). This lever (2) carries a faceted stud (5) articulated on this lever (2). The lever (2) multiplies in (B) the effort (F) exerted by the user in (A). The iron is positioned according to the clamp, udder, quarter or sponge area to be closed. So when the horseshoe is in contact with the central cam (IC) in (D) and on one face of the facet block (3) in (E), the user by pulling the lever (2) in (A ) exerts a force on the iron branch in (B) via the stud (5) allowing the bending of the zone (DB). The contact in (D) is made on the internal bank, the contacts in (E) and (B) are made on the external bank. The articulation of the studs (3) and (5) allows freedom of rotation so as to adapt to the different iron curvatures and to the angular deformation of the iron.

The eccentricity of the studs (3) and (5) makes it possible to adapt to the size of the iron and its width.

With reference to these drawings in the case of FIGS. 4 and 5, the device comprises the fixed frame (1), supporting the fixed central cam (IC), the stud to

-5facettes (3) articulated on this frame (1) and the lever (2) articulated at the level of the central cam (IC). This lever (2) carries a faceted stud (4) articulated on this lever (2) at a certain distance from the articulation of the stud (5) to deform a different zone of the iron.

The lever (2) multiplies in (P) the effort (F) exerted by the user in (A). The iron is positioned according to the udder, quarter or sponge area to be closed. So when the horseshoe is in contact with the central cam (IC) in (D) and on the faceted stud (3) in (E), the user pulls on the lever 2 in (A) exerts a force on the iron branch in (P) via the stud (4) allowing the bending of the area (DP). As in the case of FIGS. 1, 2 and 3, the contact in (D) is made on the internal bank, the contacts in (E) and (P) are made on the external bank. The articulation of the studs (3) and (4) allows freedom of rotation so as to adapt to the different curvatures, widths of iron and the angular deformation of the iron. The offset of the studs (3) and (4) makes it possible to adapt to the range, the size of the iron and its width.

With reference to these drawings, in the case of FIGS. 6 and 7, the device comprises the fixed frame (1) supporting the fixed central cam (IC), the faceted stud (3) articulated on the frame (1) and the lever (2) articulated at the level of the central cam (IC). The faceted stud (3) has the extra thickness (SEP) which is used in this case. The lever (2) carries the faceted stud (4) articulated on this lever (2). The lever (2) makes it possible to multiply in (P) the force F exerted by the user in (A). The iron is positioned according to the area to be closed. So when the horseshoe is pressing on the central cam (IC) in (D) and on the extra thickness (SEP) of the faceted stud (3) in (E), the user by pressing the lever (2) in (A) exerts a force on the iron branch in (P) by means of the stud (4) allowing the bending of the zone (DP). The articulation of the studs (3) and (4) allows freedom of rotation so as to adapt to the different curvatures, widths of iron and the angular deformation of the iron. The eccentricity of the studs (3) and (4) makes it possible to adapt to the size of the iron and its width.

With reference to these drawings, in the case of FIG. (8), the device comprises the fixed frame (1) provided with an end stop (Tl), and the lever (2) articulated at the level of the cam central (IC). This lever (2) carries an end stop (T2). The tabs (Tl) and (T2) are located behind the plane of the lever (2), opposite the faceted studs (3), (4), (5). The tabs (T1) and (T2) have a vee shape. The iron is positioned in abutment at the bottom of the tabs (Tl) and (T2), sponge contact in (V) on (Tl) and sponge contact in (H) on (T2). The lever (2) multiplies in (H) the effort (F) exerted by the user in (A). Thus the user by pulling on the lever (2) in (A), exerts a force on the sponge of the iron in (H) making it possible to close the branches of the iron. Support surfaces (SI) on the frame, (S2) on the lever (2) keep the iron in the deformation plane. Figure 8: Closing of the branches of the iron by its end.

With reference to these drawings, in the case of FIG. (9), the device comprises the frame (1) provided with an end stop (T3) and the lever (2) articulated at the level of the cam (lC) This lever is fitted with an end stop (T4). The tabs (T3) and (T4) are located behind the lever plane (2) opposite the faceted studs (3), (4), (5). The tabs (T3) and (T4) have a vee shape. The iron is positioned in abutment at the bottom of the cleats (T3) and (T4), sponge contact in (K) on (T3) and contact in (J) on (T4). The lever (2) multiplies the effort (F) exerted by the user at (A). Thus the user by pulling the lever (2) at (A), exerts a force on the sponge of the iron at (J) allowing the branches of the iron to be opened. A support surface (S3) on the frame keeps the iron in the deformation plane.

With reference to these drawings, in the case of FIG. (10), the device comprises the fixed frame (1) provided with a cleat (T5) and the lever (2) articulated at the level of the central cam (IC). This lever (2) carries a cleat (T6). The tabs (T5) and (T6) are located behind the plane of the lever (2), on the same side as the end tabs (Tl) and (T2). The tabs (T5) and (T6) have a rectangular, hexagonal or circular section. The iron is positioned, external edge contact in (Q) on the cleat T5, external edge contact in (R) on the cleat (T6). The lever (2) multiplies the effect (F) exerted by the user in (A). Thus the user by pressing the lever (2) at (A) exerts a force on the branch of the iron at (R) allowing the iron to be closed. Changing the position of the iron changes the

- 7position of the contact points (Q) and (R) on the branches, therefore to modify the deformation zone (QR) desired.

With reference to these drawings, in the case of FIG. (11), the device comprises the fixed frame (1) provided with a cleat (T7) and the lever (2) articulated at the level of the central cam (IC). This lever (2) carries a cleat (T8). The tabs (T7) and (T8) are located behind the plane of the lever (2), on the same side as the end tabs (T3) and (T4). The tabs (T7) and (T8) have a rectangular, hexagonal or circular section. The iron is positioned, internal contact in (S) on the cleat T7, internal contact in (U) on the cleat (T8). The lever (2) multiplies the effect (F) exerted by the user in (A). Thus the user by pulling on the lever (2) at (A), exerts a force on the branch of the iron at (U) allowing the iron to be opened. The modification of the position of the iron makes it possible to change the position of the contact points (S) and (U) on the branches therefore to modify the desired deformation zone (SU).

With reference to these drawings in the case of Figures (12) and (13), the device comprises the fixed frame (1) supporting the fixed stepped central cam (1C) + (1CE) and the lever (2) articulated at the central cam (1C) + (1CE). The lever (2) carries the faceted stud (4) articulated thereon. The lever (2) multiplies in (P) the effort (F) exerted by the user in (A). So when the horseshoe is in contact with the central cam on the lower part (IC) or the upper part (ICE) in (R) and on the facet block (3) in (E), the user pulls on the lever (2) in (A) exerts a force on the branch of the iron in (P) via the stud (4) allowing the opening of the zone (PR). The contacts in (E) and (P) are made on the internal banks, the contact in (R) is made on the external bank. The iron is positioned according to the area to be opened. The articulation of the studs (3) and (4) allows freedom of rotation so as to adapt to the different iron curvatures and to the desired angular deformation. For small irons the use remains the same, possibly using the extra thickness (SEP).

The iron is placed perpendicular to the plane of the lever (2). The iron is positioned according to the udder, quarter or sponge area to be plumbed. So when the horseshoe is pressing on the central cam (IC) in (M) and on the faceted stud (3) in (N), the user by pressing the lever (2) in (A) exercises an effort on the iron branch in (L). The articulation of the pads (3) and (4) allows freedom of rotation so as to adapt to the different plumbing of the iron, the different sizes of iron and the desired deformation. For small or less thick irons, the use remains the same, if necessary using the extra thickness SEP of the facet block (3).
