Abstract: A linear coupling device is disclosed for a play-free, safe and dust-protected transmission of large tractive, alternating or radial forces by means of coupling members comprising of fir tree-shaped cones. The coupling members are secured together in combination with corresponding connection members comprising of a plurality of segments and a locking member comprising of a sliding coupling sleeve.

Abstract: A support assembly includes a plurality of linear supports each of which is formed of at least three longitudinal members juxtaposed in a predetermined substantially parallel relationship to one another networked together with brace means. At least two linear supports are connected by way of a set of curved connecting bars to give a shaped overall structure. In other aspects of the invention mounting brackets for use in connection with, for example, the inventive assembly are disclosed. One bracket is for mounting atop a triangular section while another bracket is substantially triangular at one end and extends laterally to a common support point distal to a substantially vertical supporting member.

Abstract: A clamping jaw device is used to couple sonic energy generated by an orbiting mass oscillator to a pipe string for transmission down the string to a downhole work area. The clamping jaw device includes a pair of similar clamping jaws, each forming a half section of a hollow cylinder. The jaw device has a head portion, a main body portion, a neck portion joining the head portion to the main body portion and indented from the head portion and a flange at the bottom end of the main body portion. The pipe string is retained between the jaws by means of a jaw lock member which comprises a flat ring slidably mounted on the main body portion and adjustably positionable therealong, the lock member being seated against the flange at the bottom end of the main body portion to hold the jaws in a closed clamping position against the pipe string.

Abstract: A bulk storage container (10) has a cylindrical body section (12) joined at its lower end to a tapering conical section (14) which terminates in an outlet (16) for the container. A cylindrical skirt section (18) of the same diameter as the body section (12) surrounds the conical section (14). The body section (12), the conical section (14) and the skirt section (18) are joined by way of a plurality of joint members (50) arranged side by side around the periphery of the container (10). Each joint member (50) has first attachment devices (52) for attachment to the body section (12), second attachment devices (60) for attachment to the conical section (14) and third attachment devices (56) for attachment to the skirt section (18). The first and third attachment devices (52,56) are vertically spaced so that the supporting force for the body section (12) is transmitted through the joint members (50). The second attachment devices (60) are vertically located between the first and third attachment devices.

Abstract: A method and apparatus for attaching blades to a rotating structure where the blades are clamped by blocks at the leading and trailing edges then to an intermediary member which is attached to the rotating structure.

Abstract: The present invention relates to a device for connecting the ends of cable, wire or other cylindrical objects together. More particularly, the invention includes an elongated jaw assembly with openings at each end adapted to receive the objects to be joined. The outer surface of the jaw assembly is tapered towards the ends to slidingly receive collars which, when driven onto the jaw assembly, axially compress the jaw assembly down around the inserted objects.

Abstract: Warehouses, moving vans, buses, railroad cars, and cargo planes, adapted for storage or transport of cargo generally have tie-down studs or anchor bolts in their floors and walls. In order that cargo may slide across the floors or walls without interference the tie-down studs are mounted in recesses so that they do not extend beyond the floor or wall surface. These recessed studs have the disadvantage that objects to be attached thereto must be adapted to fit them. This invention provides an anchoring assembly which effectively converts the recessed anchor stud to an upwardly extending anchor bolt.

Abstract: The present invention involves a machine for cutting earth formations, of the type comprising a vehicle body, a cutter drum mounted on the vehicle body, and a drive mechanism for rotating the cutter drum. The cutter drum includes a plurality of segments of a cylinder, and a connector for connecting the drum segments together. The drum segments each include at one end thereof a reaction surface inclined in a direction extending longitudinally outwardly and radially inwardly. The connector comprises a connector ring and a fastener. The connector ring includes an inner peripheral surface inclined in a direction complimentary to that of the reaction surfaces such that the connector ring is able to fit over the reaction surfaces. The fastener imposes generally longitudinally inward forces on the connector ring to urge the inner peripheral surface of the ring into wedging engagement with the reaction surfaces to urge the drum segments together.

Abstract: A master cylinder has a first piston and a second piston slidably disposed respectively in two piston chambers of different diameters, reduced diameter stems projecting from the opposing end portions of the pistons respectively, a flange formed around the outer periphery of each of the stems, and a split sleeve consisting of two or more co-operating elements and having stepped portions in the inner circumference thereof at the opposite ends respectively, the split sleeve being restrained in a cylindrical shape with the stepped portions engaging with respective flanges thereby connecting the two pistons with each other.

Abstract: This specification discloses a method and construction for joining the ends of concrete reinforcing bars which permits the development of both tension and compression in the bars. A joining member compressively engages adaptor members integrally joined to the ends of the bars and reacts any forces tending to separate the bars, and further permits transmittal of compressive forces therebetween.

Abstract: The bracket assembly comprises a pair of opposed channel plates supporting a fence board clamped therebetween, and having a bearing sleeve portion extending from one of said plates through a bore in the fence post in which said brackets are mounted, the other of said pair of plates having a bolt extending therefrom through said sleeve, and a nut on the end of the bolt for suitably tightening a washer on said bolt against said post and the outer end of said sleeve.

Abstract: A fitting for connecting a structure to an advanced composite tube, where the tube consists of high strength fibers embedded in a supporting matrix material. The fitting comprises a narrow sleeve bonded to a composite tube, split rings engaging the ends of the sleeve and overlying threaded rings fastened to the structure to be connected to the tubes, said rings when threaded together fixedly engaging said split rings. This assembly provides a secure, removable fitting while avoiding penetrations in the composite tube.

Abstract: A rod repair splice having a pair of trough shaped bodies each with a rod embracing arcuate flange at one end thereof. The bodies are diametrically mounted on the rod to be repaired with the respective arcuate flanges thereof disposed at longitudinally opposite ends of the splice. Each of the bodies is welded along their opposite longitudinal side edges to the peripheral surface of the rod sections. Each axial end portion of the bodies includes three distinct camming surfaces which slope from the inner surface of the body adjacent to the rod to be spliced to the outer surface of the body. The sloping surfaces thereby avoid shoulders which might cause hangup upon axial movement of the repaired rod by camming an axial interference in a radially outward direction out of axial contact with the splice.
