Abstract: A friction rock stabilizer includes an elongated metal tube having and interior and an exterior surface with a distal end and a proximal end. The distal end is tapered and a flange is positioned adjacent the proximal end. The tube further includes a slit that runs substantially the entire length thereof. The tube is constructed so as to be capable of being positioned within a bore formed in the wall of a mine. An internal sleeve is located adjacent the distal end of the tube. A tapered expander is also located within the interior of the tube adjacent the distal end and is actuatable from the proximal end of the tube after the point anchor is installed in a bore. The tapered expander expands the distal end of the tube to firmly anchor the stabilizer in the bore.

Abstract: A machine for forming a metal roof panel of indeterminate length from a uniform width supply strip of sheet metal having a pair of parallel straight longitudinal edges. The machine has a series of spaced forming stations each having upper and lower shaping rollers between which the sheet metal strip is passed so as to impart a desired shape to the sheet metal strip which is uniform the length of sheet metal strip after it exits the apparatus. A stamping station located in the path of the sheet metal strip before the series of spaced forming stations is effective to form linear impressions in the sheet metal strip. The linear impressions are transverse to the longitudinal edges of the sheet metal strip, with each such impression having its lateral extent limited such that the succeeding series of shaping rollers do not impinge thereon.

Abstract: A creeper includes a torso supporting platform with a front wall, a rear wall and two opposing side walls. A pair of spaced apart recesses are formed in one of the side walls. Extending downwardly from the platform are a plurality of casters. A tool box with a front wall, a rear wall and two opposing side walls has a pair of locking tabs extending outwardly from one of the side walls thereof. Each of the locking tabs is adapted to engage a corresponding one of the recesses formed in the side wall of the torso supporting platform.

Abstract: A keeper clip for securing the joints between casings of a type having a channel for attachment to a metal door frame. The keeper clip provides a secure and attractive joint without gaps or misalignment. The keeper clip has an elongated crosspiece extending between a pair of legs and an arm. Each of the pair of legs extend normally from an end of the crosspiece. The pair of legs and crosspiece thus form a U-shaped cross section for frictional reception within the channel of the header casing. The arm extends coplanar with the elongated crosspiece along the longitudinal axis of the header casing. The arm is resiliently deformable to receive an offset overlay of a side casing between the header casing and the arm. A portion of a free end of the arm is bent in a direction away from the header casing to permit easy insertion of the offset overlay. The keeper clip may be formed of a single strip of resilient material such as spring steel.

Abstract: A fastener is disclosed for attaching a channel shaped fastening strip to a door frame or the like. The fastener comprises a pair of oppositely facing loops which are insertable into the channel of the facing strip and, in doing so, the loops frictionally engage the sides of the facing strip and secures the facing strip to the frame. At least one and preferably two tangs formed on the end of the fastener extend through it and engage the sides of an opening in the frame to detachably secure the fastener to the frame.
