 PLIERS TO WEAR HOT HORSESHOES The invention relates to the technical sector of equipment and materials used by farriers to shoe horses.

According to the prior art, the laying of horseshoes is carried out hot, the iron being at a temperature of the order of 1000 to 1200 ° C., so that it is necessary to have a tool of the articulated pliers type. as a compass to grab the iron from the heating place, bring it and transfer it next to the animal's hoof where it is fixed by studding by the farrier. This therefore requires that the operator has a support against the animal, then with both hands, hold the pliers with a certain pressure to attach the hot iron against the hoof, for about twenty seconds to make it take. Then there is the operation of nailing the iron on the hoof. These manipulations are impractical. In fact, in this implementation, the farrier, by both hands, holds the compass pliers in pressure to hold the horseshoe on the hoof, and he cannot therefore hold the animal and control its attitude, because the latter may try to slip away or move. The pressure force and duration remain in these random conditions. We will agree that the handling is impractical.

To overcome these drawbacks, it has been proposed a pair of tongs for hot carrying irons which comprises, from an articulated lever, two claws for anchoring iron from the outside, a support base on the rear part. iron and a hook at the end of an arm of the lever which is capable of coming to bear against the iron. The lever has two articulated arms connected in position by a locking latch. A hot-tongs of this nature has drawbacks, in particular in its handling and locking.

 The applicant's approach was therefore to optimize the tongs for carrying the hot iron, so as to ensure a stable hold and locking in position, by allowing manipulation of the tongs with one hand, according to all the operations of use and non-use.

According to a first characteristic of the invention, the tongs for carrying hot horseshoes comprises an articulated lever, two claws for anchoring the iron from the outside, a support base on the rear part of the iron and a hook at the end of the lever arm capable of constituting a counter-support on the iron, the lever comprising a movable arm articulated with an axis disposed transversely relative to a fixing yoke secured to a fixed arm, the latter being perpendicular to the 'base, said yoke having profiled wings extending forwardly by two ends allowing the articulation of the mobile arm, and in that an elastic return means is mounted between the mobile arm and the fixing yoke, and in that locking means associated with the movable arm and the yoke authorize the locking in position of the movable arm relative to the fixed arm when holding and keeping the hot iron.

These characteristics and others will become apparent from the following description.

In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings.

The tongs for carrying the hot irons are referenced as a whole by (P) and it is intended to adapt, to be fixed on a horseshoe (1) hot, in order to translate it from the heating zone to temperature of the order of 1000 to 1200 C towards the shoeing shoe.

The iron (1) is of any known type with one or more prongs (la) on the horse's hoof, with one or more openings (lob) formed through the thickness of the iron to allow the insertion of nails, for fixing the shoe to the shoe.

The tongs for carrying the irons thus comprise a base (2) of large width and configuration and of rectangular section for coming to bear and press on the rear branches (le) of the shoeing iron. This base is secured by welding (3) or the like to a fixed arm (4) arranged perpendicularly and constituting the fixed part of a gripping and operating lever referenced

<Desc / Clms Page number 4>

 as a whole by (5). This fixed arm is of great height. Said base (2) thus allows the fixed fixing of two claws (6-7) by welding or equivalent. These claws are oriented obliquely and their front end part (6a-7a) is in the form of a hook to bear against the outer edge face (Id) of the iron. The ends (6b-7b) of the rear claws are fixed by welding to the base.

The lever (5) comprises, as a complement, a mobile arm (8) which is articulated on a fixed axis (9) disposed transversely relative to a fixing yoke (10), itself secured by welding to the fixed arm ( 4) The openings (lOb2-lOa2) authorizing the fixed position of the axis (9). This yoke thus has two profiled wings (lOa-lOb) surrounding the aforementioned arm (4) and extending forwards by two ends (l0al-lObl) close together between which is mounted the movable arm (8) by means of 'openings (loua2- lOb2). More particularly, this comprises in its central part a plate (8a) which has an opening (8b) located towards the rear, which allows the passage of the articulation axis (9), and a finger (11) projecting arranged towards the front of the plate. This is extended upwards by a gripping rod (8c) and downwards by an extension (8d) whose end (8e) forms a hook, the latter being intended to come into abutment on the iron in situation closing forceps. Furthermore, one of the wings (lofa) of the yoke thus has a projection or finger (12). A return spring (13) is thus fixed by its ends (13a-13b) on the fingers (11-12) and thus allows elastic mounting of the articulation of the mobile arm (8) relative to the fixed arm (4) .

There is provided, in addition, a locking means in particular of the movable arm (8) relative to the fixed arm (4). There are shown in the drawings two preferred modes which are part of the rotational connection between the pivoting arm (8) and the yoke (10) allowing this articulation.

<Desc / Clms Page number 5>

Referring to Figures 7, 9 and 10, one of the wings (lOb) of the yoke has an internally slightly protruding shape (14) which is capable, depending on the position of the movable arm, of engaging in a recess (15) formed on the central plate (8a) of the movable arm. There is therefore a tangential contact between the wing of the yoke and the plate with a certain elastic capacity of deformation, so that in the locked position corresponding to the locking position illustrated in Figures 1 and 3 of the drawings, the clamp is maintained blocking the hot horseshoe by its claws and beak for transport. The release of the lock and therefore the opening of the clamp is effected by a slight offset action allowing the release of the projecting shape (14) of the recess (15).

In the variant illustrated in Figures 4,5, 6 of the drawings, the locking in position of the movable arm relative to the fixed arm (4) is carried out as follows. It is the hinge pin (9) which has at least one of its ends a projection (9a). In this case, the axis is mounted linked to the movable arm (8), and therefore pivots in its housing in the openings. The yoke (s) of the yoke has projections (16) which are bypassed by the projection (9a) which is formed on the axis during the pivoting of the movable arm and therefore of the axis (9), and this at the 'against elastic return means. This results in a locking position of the movable arm relative to the fixed arm.

The advantages emerge clearly from the invention. This highlights the new construction of the shoeing pliers, as well as the easy handling thereof by the operator in all circumstances when the hot iron is placed on the animal.
