Abstract: An expansion shell assembly of the type including a pair of unitary expansion shell elements, each having two leaf members joined adjacent their lower ends by bridge portions with a bail fixedly attached at terminal ends to outer surfaces of the bridge portions to maintain the expansion shell elements in assembled relation. The bridge portions include a recessed area extending continuously between its upper and lower edges. The recessed areas are divided into two portions, with the lower portions substantially narrower than the upper portions, wherein terminal ends of the bail are secured. Opposing edges of the shell elements are in spaced, substantially parallel relation with the space therebetween free of any structure extending into such space over the full axial length of the shell elements. Relieved areas extend into the inner surfaces of the bridge portions to provide a clearance for the lower end of a tapered camming plug which is moved between the shell elements to effect radial expansion thereof.

Abstract: An improved, radially expansible shell for use in a mechanical expansion anchor and an anchoring system including such a shell in combination with a resin grouting mix, in a drill hole of predetermined diameter. The shell includes a plurality of leaf portions having internal surfaces for engagement by a tapered camming plug as the shell is expanded, external surfaces having a maximum diameter less than that of the drill hole, and side edges. A row of tapered teeth extends outwardly from the external surface of each leaf along one of the side edges thereof. The distance from the central axis of the shell to the crests of the teeth is substantially equal to the radius of the drill hole. The teeth frictionally engage the drill hole wall to retard rotation of the shell and ensure the desired expansion. When the anchor is used with a conventional, two-compartment resin package, the resin components may flow around the shell into the annular space between the external surfaces of the leaves and the drill hole wall.

Abstract: A one-piece, malleable iron, expansion shell, and a leaf of such shell, for use in an expansion to be installed in a relatively small (about 1") diameter bore hole with a conventional size (5/8") bolt. The expansion shell, and individual shell leaves have unique features contributing to the effectiveness of the anchor when used either with or without a resin grouting mixture. The slots or spaces between adjacent shell leaves include upper and lower portions, each of constant width, the lower portion being wider than the upper portion, whereby the leaves are narrower in the area where they are bent outwardly from the closed ring at the base than in the area where they are compressionally engaged between the plug and the hole wall. Upper portions of the inner leaf surfaces taper toward the shell axis and the side edges of such surfaces taper toward one another from the upper, free ends of the leaves toward the lower ends. A first group of gripping teeth or serrations on the outer leaf surfaces near the lower ends of the leaves are deeper than a second group outwardly adjacent the plug contact area.

Abstract: A mine roof mechanical anchor having the usual expansion shell and tapered nut is fitted with a bail having legs secured to the shell and a medial portion extending over and contacting the nut, maintaining the latter in assembled relation with the shell, and having an opening aligned with and slightly smaller than the threaded opening in the nut. Bail extension structure, having a pair of legs attached to the legs of the first bail and a medial portion aligned with and spaced from that of the first bail, provides a means of breaking the casing and mixing the contents of a standard resin cartridge inserted in a bore hole in a mine roof ahead of the anchor and threaded bolt or rebar on which it is supported. The anchor and associated structure are rotated together with the roof bolt or rebar due to interference thereof with the smaller opening in the medial portion of the bail. After the resin cartridge is broken and contents mixed, rotation is stopped for a few seconds to allow the resin to begin to set and restrain further rotation of the anchor. When rotation is resumed the bolt or rebar is forced through the opening in the bail, but the tapered nut is not advanced to expand the shell until the end of the bolt or rebar contacts the medial portion of the bail extension structure. The bolt may then be tensioned and is anchored mechanically and by the hardened resin.

Abstract: An otherwise conventional mine roof expansion anchor of the bail-type is provided with a tubular retainer member encircling the shell leaves and having an external cross-dimension significantly (e.g., at least 0.10") greater than the diameter of the drill hole in which the anchor is to be installed. Thus, as the anchor, supported on the end of a roof bolt, is advanced into the drill hole in the usual manner, the tubular element is pushed off the anchor by contact with the surface surrounding the drill hole, thereby eliminating the previously required manual removal of the retainer. The tubular retainer has the same cross-sectional configuration in all planes perpendicular to its central axis throughout its full length, preferably being formed as a plastic extrusion.

Abstract: A nut member of special design is disclosed in conjunction with other elements to provide a post-tensionable mine roof support assembly. The nut member includes an upper, stem portion extending through the opening in a support plate and a lower, base portion of larger diameter than the plate opening. A through opening in the nut includes an internally threaded portion at the upper end of the stem and an internal socket for wrench engagement at the lower end of the base. Between the threaded portion and socket is an internal bore having a diameter greater than the threaded portion. Breakable means, preferably annular in form and cast integrally with the rest of the nut member, extends into the bore to a position with the cylindrical plane extending downwardly from the threaded portion. Thus, a threaded end of an elongated rod may be engaged with the threaded portion of the nut, extending into abutting engagement with the breakable means, and the other end of the rod advanced into a mine roof drill hole behind a standard resin cartridge. The cartridge is broken and the contents mixed by rotating the nut member, and thereby the rod, by a wrench engaged with the socket. By stopping rotation for a few seconds and allowing the resin to harden sufficiently to prevent further rotation of the rod, excess torque applied to the nut member will cause the threaded rod end to break through the breakable means, permitting the nut to be tightened against the support plate and the rod tensioned with the end of the rod extending into the bore area between the breakable means and the socket.

Abstract: An article for assisting in the mixing of components of a resin grouting material within a drill hole in a rock formation to form a hardenable mass anchoring the threaded, distal end of an elongated bolt in the hole. The article includes an annular base portion having a central, through opening for threaded engagement with the bolt, and at least one leg extending from the base portion in a direction substantially parallel to the axis of the opening. The article is rotated together with the bolt, the leg having leading and trailing edges with respect to the direction of rotation. The leading edge is a flat surface substantially parallel to the axis of the bolt and the trailing edge is a relatively sharp, linear edge, non-parallel to the bolt axis. The article may be employed in chemical anchors with a single leg extending from the base portion toward the distal end of the bolt, or with a pair of legs extending in opposite directions from the base portion. In another embodiment, the article is employed in a combination chemical-mechanical anchor with the leg extending away from the distal end of the bolt, upon which the mechanical anchor is mounted with the lower end of the shell contacting and supported by the base portion of the article. Downward force exerted by the shell during expansion strips the threaded engagement of the article with the bolt.
