摘要： The invention pertains to a process and device for actuating a percussive tool by means of a free piston (4) which is moved back and forth with compressed air, to a device for carrying out the process and to a hammer drill and a crushing bit on which this process and device are based. In the rotary piston compressor unit an inner (2) and an outer rotor (3) turn in an intermeshed rotation, a compression space and a suction space being formed alternately on radially offset sides of the inner rotor. The piston (4) moves axially in a hollow space of the inner rotor (2), which has front (2.1) and rear (2.2) control channels, which have axially offset apertures near the two ends of the hollow space of the inner rotor, with one aperture being turned to the compression space while the other is turned to the suction space and vice versa, so that the piston is moved back and forth as a result of the alternating directions of compression and suction.

摘要： Un appareil de démolition (60), fixé à un élément mobile en forme de flèche (20) monté sur une machine, comprend une structure de support (64) qui soutient un plongeur de choc (68) et un plongeur d'entraînement (80). Les deux plongeurs (68, 80) sont montés adjacents l'un par rapport à l'autre et sont mobiles par rapport à la structure de support (64). Un ressort de compression (76) oblige le plongeur de choc (66) à se mouvoir à partir de la structure de support (64). Le plongeur d'entraînement (80) comprend un dispositif à loquet (86) qui s'engage dans une partie (72) du plongeur de choc (68). Lors du fonctionnement, la structure de support (64) se déplace en direction d'une surface devant être démolie. Le plongeur d'entraînement (80) s'engage dans la surface et reste fixe, pendant que la structure de support (64) continue son mouvement en direction de la surface. Pendant ce temps, un mouvement relatif s'effectue donc entre la structure de support (64) et le plongeur d'entraînement (80). Un loquet (86), soutenu par le plongeur d'entraînement (80), s'engage dans une partie (72) du plongeur de choc (68) et maintient le plongeur de choc (68) dans une position fixe par rapport au plongeur d'entraînement (80). Le mouvement de la structure de support (64) en direction de la surface est donc contré par le ressort (76) et les forces de compression du ressort (76) augmentent, au fur et à mesure que se produit ce mouvement. Pendant que la structure de support (64) se déplace en direction de la surface, une butée (90), soutenue par la structure de support (64), s'engage dans le loquet (86) et le libère de son engagement avec le plongeur de choc (68). Le plongeur de choc (68) est ainsi libéré en vue d'un mouvement rapide, dans lequel il est entraîné par le ressort (76), et heurte la surface pour la démolir.

摘要： Apparatus in the form of an attachment device for an electric drill machine, for removing putty and other residuals in a window frame at the exchange of a window pane. The apparatus comprises a transmission (1), which transforms the rotational movement of a power source into reciprocating movement, which is imparted to a tool. The reciprocating movement is a linear movement having a saw-tooth-shaped form with a rapid, instantaneous movement outwards and a slower returning movement. At the output spindle of the power source a cam member (3) is attached having a helically shaped cam surface (5), which is ended by a radial step (6). The transmission includes further a cam follower (7) and an angle link (9), which connects the cam follower (7) with the impact shaft (15), at which the tool is mounted. The spring device (16) urges the impact shaft outwards and the cam follower (7) against the cam surface (5). When the cam follower (7) follows the helical path of the cam surface (5), the impact shaft (15) is pulled inwards and the spring device (16) is comprimated. When the cam follower (7) reaches the radial step (6) the spring device (16) is released and a rapid movement outwards is imparted to the impact shaft.

摘要： A recoil and positioning mechanism for a reciprocating member (32) utilizes an accumulator (50) to absorb recoil force. The reciprocating member (32) is reset after recoil to a predetermined position to avoid contact with a force imparting eccentric drive (20). This mechanism is particularly useful in absorbing recoil and repositioning the intermediate impact link of a rock breaker.

摘要： A dwell cycle crank configuration for converting reciprocating linear motion to rotary motion includes: a follower, a top roller, a bottom roller, and a body. The top roller has a bottom portion removed. The removed bottom portion of the top roller is adapted to fit the top of the follower. The bottom roller has a top portion removed. The removed top portion of the bottom roller is adapted to fit the bottom of said follower. The top and bottom rollers are positioned within the body where each roller is adapted to rotate for allowing the follower to ride between the rollers within the body in an S- shaped pattern.

摘要： Rock breaking apparatus includes a guide column (112) within which a weight (12) falls under gravity to strike a tool (134). A piece (146) of shock-absorbing material is located at or near the base of said column such that it enables force to be transmitted from said weight (12) to the tool (134), whilst minimising the effects of the impact of said weight (12) on other parts of the apparatus. The piece (146) of shock-absorbing material has an aperture therethrough, for the passage of the tool (134). The tool (134) may have a recessed portion (140) which co-operates with a retaining pin (144) located substantially at right angles to the direction of motion of the tool (134). The apparatus may also have operating means, including means for raising a weight, means for holding a weight in one of a number of positions and means for allowing said weight to fall.
