Abstract: The invention relates to an expansion, anchor (10) comprising an expansion sleeve (12) which is divided into expansions (18) by means of longitudinal slots (14) arranged in the front section in the direction of placement (16) of the expansion sleeve (12) and also has an inner thread (20) in the rear section in the direction of placement (16). The expansion anchor (10) further comprises an expansion body (22), which preferably has the shape of a cone stump that tapers conically in the direction of placement (18), the conical stump being arranged in the front section in the direction of placement (16) of the expansion sleeve and inside the expansion sleeve (12).

Abstract: A forged, integral bolt (20) has a head, a tapered neck (22), a shank, and a plurality of plastically deformable, raised, contact surface portions (31) uniformly positioned adjacent the neck and extending axially and radially of the bolt for spreading a load applied to the bolt. Each raised portion has a base portion contiguous the neck, and an elongated, V-shaped, ridge portion raised above the base which is constructed to contact and fay with a congruent wall portion of a bolt bore (12) in a support structure. The bolt may have various shapes. (FIGS. 1-3, 10-23). The ridges may extend up onto the sides of the head. (FIG. 9). The ridge portions and base portions may be integrally forged as a pair of symmetrical, self-aligning, inserts (40) separate from, but mating with, opposite sides of the neck when a load is applied to the bolt.

Abstract: A stone facing section anchor mounting system has a special hole configuration, in facing stone, that will not rotate while being installed, and because of its installed angularity and pressure points will not tend to rupture or pull out of the stone. The anchor system holds beyond the lateral strength of the stone itself when the stone is at the cracking point. The superior holding power of the present anchor and its minimum edge distance eliminates the kerf and aluminum "J" structure and silicone used with other anchors, and while having the advantage of being hidden it also has the holding power of a through bolt. Fan nut anchor holes in facing material are made with ease to tolerances required. The anchors do not rotate during installation and use a lock nut that does not work loose in transit and the anchor is such, with accurate hole predetermined angularity that installation can be made without over tightening occurring.

Abstract: This key comprises a pair of elongated blocks each having a tapered recess; a tapered pin adapted to be inserted in a tubular tapered portion which is formed by bringing the pair of blocks together in such a manner that the tapered recesses confront, and mutually displaceable in the axial direction; and a clamping member adapted to be screwed into a threaded portion provided on one end of the tapered pin or the tubular tapered portion. The key obtained by assembling these parts can be fitted into a key groove provided between a driving member and a driven member. The clamping member is rotated to mutually displace the tapered pin with respect to the tubular tapered portion in the axial direction, thereby separating the blocks from each other, thus pressing the outer walls of the blocks against the inner wall of the key groove. As a result, the key is firmly fitted into the key groove, and the drive member and the driven member can be securely coupled together with a higher reliability.

Abstract: When aligning heavy shafts, their flanges (4, 5) are first roughly aligned, after which an expander bolt (10) is inserted through the roughly aligned flange holes (16). The expander bolts have a conical core (6) and internally conical sleeves (1, 2) arranged axially separated from each other thereon. First the sleeves (1, 2) are inserted into the relevant flange (4, 5) to the plane (50) between the shaft flanges. Then the bolt core (6) is inserted through the sleeves (1, 2), the front end of the conical section (64) passing the plane (20) between the sleeves (1, 2). In order to keep the nearest sleeve (1) at the plane (50) when the bolt core (6) is being drawn, a spacer (8) is used which is placed on the drawn end of the bolt shaft (6) and has a head (86) located between a drawing device (7) fitted on the bolt shaft (6) and the exposed end surface (41) of the adjacent shaft flange.

Abstract: Disclosed is an expansible fastening device (10) for placement in a hole preformed in a base member for use in attaching a component part to the base using a conventional nut (24) and bolt (26). The fastening device includes a fastener body (12) having two body sections (28a, and 28b). The body sections when positioned together form a central cavity (30) within the fastener body which encloses and retains the nut and a wedge (14). Each longitudinal section includes a fin (16) which extends longitudinally and projects radially outward from the central region of each body section. Further, each body section includes primary and secondary teeth (18 and 20) which extend circumferentially about the outer surface of the sections. In operation the bolt is engaged with the nut and rotated, pushing the wedge from the fastening device. As the wedge is driven away from the nut, the teeth and fins are driven into the base member.

Abstract: An expansion anchor stud comprises an expansion anchor for gripping a hole in a surface, an axially-aligned, externally threaded stud of substantially the same outside diameter as the anchor and engaging the distal end of the anchor, and an axially-aligned bolt extending through a hole in the anchor and engaging the stud. A head on the proximal end of the bolt abuts the proximal end of the anchor, and external threads on the bolt engage internal threads in a hole extending through the stud. The anchor is expanded by a tool inserted into the distal end of the hole in the stud to engage the distal end of the bolt and rotate the bolt relative to the stud, thereby axially compressing, and hence expanding, the anchor. The distal end of the stud extends, in use, through a hole in a panel being mounted to the surface so that a nut may be threaded onto the external threads of the stud to secure the panel to the surface.

Abstract: An expansion anchor stud comprises an expansion anchor (16) for gripping a hole (25) in a surface (24), an axially-aligned threaded stud (14) of substantially the same outside diameter as the anchor (16) and engaging the distal end of the anchor (16) for being disposed in a hole (26) in a panel (27) mounted to the surface (24) and having a hole (28) therethrough, and an axially-aligned bolt (12) extending through the hole (28) in the stud (14) and engaging the anchor (16) and limited in insertion by the distal end of the stud (14).

Abstract: The invention provides for a fastening arrangement for a screening or lining panel in which the fastening arrangement includes half-tubular protrusions along the periphery of the panel which can fit in pairs into corresponding apertures in a support frame. The bore of each half-tubular protrusion is blanked off so that when a pair of such protrusions are fitted in an aperture in a support frame, a blind bore is formed. The fastening means further includes a pin which can be inserted into the bore formed by a pair of protrusions fitted into an aperture. The pin when inserted into the bores of the protrusions spreads the ends of the protrusions and thereby fastens the panel to the support frame.

Abstract: A coupling device for two flanged shaft ends is disclosed. A tapered pin bolt having a conical shank is employed within a complementary, internally tapered expansion sleeve having longitudinal slit. The pin bolt and sleeve extend through aligned bores provided in the flanges. The pin bolt is externally threaded on its opposite ends extending from the conical shank. A nut having an internal, axially extending and pin arrangement is mounted over each respective end of the pin bolt.

Abstract: A connector for connecting two rotors (2, 4) together, said connector having a plate (1, 3) on the end of each rotor.It has clamping bolts (5) and a plurality of fixing components (6) for the plates (1, 3). Each fixing component (6) has a sleeve (17) cut in two. The sleeve is cylindrical on the outside and conical on the inside and is disposed in precision-reamed bores (12, 14) of the same dimensions in the two plates, the bores of one plate facing and being situated exactly adjacent to those of the other when the rotors (2, 4) are aligned. A shank (20) which has a conical portion (21) pushes back the parts of the sleeve (17) against the walls of the bores (12, 14) thus connecting the plates together without play.In the case of normal operation, the connector has high resistance to shearing due to the fact that there are no stresses in the components (6). In the case of a torque greater than the normal torque, the parts of the sleeve 17 are deformed but can be very easily extracted.

Abstract: An expansion anchor assembly is made up of an anchor bolt and an expansion sleeve encircling and secured in an annular recess on the bolt. Adjacent the annular recess, the anchor bolt has a frusto-conical section. The expansion sleeve has diametrically opposite reduced thickness wall sections with a projection extending outwardly of the surface of the sleeve along each of the reduced thickness wall sections. When the expansion anchor assembly is inserted into a prepared borehole and the frusto-conical section is drawn into the sleeve, the sleeve breaks into axially extending sections along the reduced thickness wall sections and a uniform contact is provided between the sleeve section and the borehole surface.

Abstract: The present invention is a wall anchor having a novel finger configuration. This wall anchor has a head and barrel portion with a bore extending therethrough and laterally expandable fingers in general alignment with the bore. Instead of a straight channel, a channel having curved portions separates the fingers. The curved portions of the channel define ramp surfaces that at least partially extend into the path of a securing member created by the bore. Thus, when a securing member, such as a bolt, pin, screw, nail or similar object is inserted into the bore to secure the wall anchor to the wall, the securing member contacts the two ramp surfaces, separating the fingers. As the fingers separate, a portion of the fingers near the ramp surfaces deform such that the ramp surfaces rest on an outer portion of the securing member, thus providing a securing force for connecting the wall anchor to the wall and relieving stress on the area at which the fingers are connected to the barrel.
