Abstract: The present invention relates to a peg with insert sleeve as well as a process for using the peg for fixing posts or sticks in the ground.

Abstract: A mobile apparatus for driving different objects into the ground by impact, comprising a carrier structure supporting a swinging element along which slides a mass whose movements are controlled by a cable. The swinging element has a tubular structure divided longitudinally into two parts each comprising at least two surfaces for guiding two opposite zones of said mass so as to be able to provide alone longitudinal guiding of said mass and means for connecting these two parts together with free longitudinal sliding of one of the parts with respect to the other.

Abstract: Method of making, from a strip, (for example metallic) a peg including a prismatic sheath from at least one surface of which extends a fin shaped so as to facilitate its downward penetration into the ground and increase its strength in the transverse direction, characterized in that the method comprises: shaping a strip adapted to form a plurality of pegs so as to define on each edge thereof a straight prismatic sleeve (1, 2) having all along its longitudinal dimension an opening (11, 21) extending along its edge which connects it with the intermediate strip portion (3) joining both sleeves to each other; and cutting said shaped strip both in a direction orthogonal to the generatrixes of said prismatic sleeves (1, 2) to form sections (A.sub.1, B.sub.1, A.sub.2, B.sub.2) the length of which is equal to the vertical dimension of the peg, and, in each said section, along a diagonal plane (A.sub.1, B.sub.1). The method can be used for making pegs for fences.

Abstract: A tool for boring cavity holes in concrete walls and the like comprises a cutting blade pivotally mounted about a transverse pin at the end of an elongate body and having a camming profiled portion. A ball is placed at the bottom of the hole which has first been bored with a conventional drill and the tool cutting blade is brought into contact with the ball while causing rapid rotation of the tool body and exerting an axial pressure. The ball cooperates with the blade camming profiled portion so as progressively to orient the blade in a transverse direction.

Abstract: A tool for driving into the ground pegs having a central sleeve and projecting fins, said pegs being adapted for anchoring stakes into the ground, said tool comprising a rod-like body with pointed lower end and a projecting central part forming a lower transverse surface which is adapted for bearing on the projecting fins of the peg and a ram member sliding along the upper part of the rod-like body to impart blows on said projecting central part. The tool of this invention has a bell-shaped member capping the projecting central part and a flat member assembled to the base of the projecting central portion. It has particularly high resistance to the blows and allows easy replacement of its most fragile parts in case of wear or breakage.

Abstract: A peg device for the fixing of posts and stakes in the ground has a rigid member shaped to permit it to be readily driven into the ground and defining a housing which can receive a base portion of the post or stake. A preferred construction has a number of metal plates forming the rigid member, each plate including a bent up edge portion welded to another of the plates, the assembly of plates being positioned so as to define a central sheath bounding the housing. The rigid member may be shaped to permit it to be screwed into the ground. For driving the peg device into the ground, a driving device may be inserted in the housing and pressure exerted on the driving device, for example by repeated operation of a ram which is slidable up and down a rod portion to abut on a stop.
