  • Patent number: 5685148
    Abstract: A drive apparatus for reversible movements of an actuator is provided with a drive element made from a shape memory alloy with one-way effect. The drive element acts upon a lever rotatable about an axle in opposition to the force of a resetting element, wherein the lever can be used as a coupling member for converting a deformation of the drive element into a movement of the actuator. The drive element is a winding with a plurality of turns of a wire, wherein the turns are fixed and arranged mechanically parallel between an anchor point and the lever so that the lever is rotatable about the axle by means of a deformation of a turn, and the tractive force acting upon the lever by means of the drive element results from the individual forces of the turns of the winding acting mechanically parallel upon the lever. The diameter of the wire is advantageously approximately equal to the standardised diameter of the crystalline grain of the shape memory alloy in the austenitic state.

  • Patent number: 4436163
    Abstract: A power operated tool includes a prime mover, an output member and a power transmission mechanism arranged to transmit rotary motion of the prime mover to a reciprocatory output member. The power transmission mechanism includes a first member mounted for reciprocating motion, a link coupled at one end to the first member, and a second member mounted for rotation about an axis transverse to the path of reciprocating motion of the first member. The arrangement is such that rotation of the second member reciprocates the first member and also imparts a cyclic partial rotation to the first member during said reciprocation. The second member has a bore therein spaced from the axis of rotation and inclined there towards. The bore has an axis which intersects the axis of rotation at an angle of about one quarter of the angle through which the first member partially rotates.

  • Patent number: 4366869
    Abstract: A hammer drill is arranged to rotate and also apply percussive force to a tool receptacle. The percussive force is transmitted from a shaft to a drive piston which, in turn, reciprocates a percussion piston which drives the tool receptacle. The hammer drill includes a housing and a bearing rotatably mounted in the housing. The shaft is rotatably mounted in the bearing and its axis extends perpendicularly of the axis of rotation of the bearing. The bearing supports a contact rim which is in meshed engagement with the shaft. The contact rim is displaceably into frictional contact with a brake member for holding the contact rim against rotation while the bearing rotates carrying with it the shaft. Due to its meshed engagement with the contact rim, the shaft rotates about its own axis causing the drive piston to reciprocate.
