Abstract: A conventional mining bore hole drill assembly having a drill mounted on a boom wherein the orientation of the drill and boom with respect to the mined material is readily adjustable. First and second inclination detectors are mounted on the boom with each detector including gravity actuated switching devices. Inclination apparatus further including read out devices positioned at the equipment operator's station to continuously allow the operator to determine whether the bore hole is being drilled at the proper angle of inclination.

Abstract: A device for indicating the angular movement of a tube bender and the like is disclosed comprising a plate assembly having an alignment groove for attaching, in desired position, the plate to the elongated handle of the tube bender, and wherein the plate assembly has an arcuate spirit level with an angular movement position indicator air bubble inside and has angle marked surface adjacent the arcuate spirit level.

Abstract: A leveling mechanism having bubble levels is removably attachable to a hand-held power drill. In one form, the leveling mechanism includes a drive shaft coupled between the drill and a chuck for rotation therewith. The drive shaft is rotatably mounted to a support, and the support is held stationary relative to the drill housing. The support may include first and second surfaces parallel and perpendicular, respectively, to the axis of rotation of the drive shaft for supporting first and second bubble levels. Alternatively, the support may include a support plate and a level plate hinged thereto for supporting one or more bubble levels; a grooved alignment plate engages the edges of the support plate and level plate for maintaining a predetermined angular relationship therebetween. In another form, the leveling mechanism is removably attached to the front face of the drill housing.

Abstract: A sighting device for enhancing a golfer's putting accuracy comprises an elongated vertical sight and a liquid level, which are provided by a compact hand-held, semitransparent or translucent casing with particular indicia and contained liquid. After the golfer moves to a position at which he views the ball and the cup along their shortest interjacent path, he views the position of the cup with respect to the ball in reference to the sight and plumbs the sight in reference to the level. A correct indication of how the ball will break thereby is provided.

Abstract: A hanging device for pictures comprising a wall pad and a picture frame pad wherein the wall pad includes structure defining an upwardly opening pocket and is adapted to be adhered to a wall surface and wherein the picture pad includes a downwardly and outwardly extending portion sized for receipt in the wall pad in hooked-up engagement to support the picture and wherein a leveler bubble gauge may be provided on one or both of the pads to orient the pads into a horizontal attitude for correct display of the picture.

Abstract: A hollow body is provided defining a pair of openings therein opening outwardly of the interior of the body in directions disposed at generally right angles relative to each other. A substantially planar light reflective surface is mounted within the body for reflecting light rays entering the body through one opening outwardly from said body through the other opening and a finger engageable support member is provided for engaging and support from a finger portion with said finger portion extending along a predetermined path relative to the support member. Mounting structure is provided for mounting the support member on the exterior of the body for adjusted angular displacement of the support member relative to the body about an axis disposed at generally right angles relative to one of said directions and said path.

Abstract: An alignment device comprising a plurality of hollow arcuate sections secured together at their inner edges so as to form a hollow center with a base support member, an aperture for admitting fluid and scalar indicia about the outer edges of the arcuate section. The device may be adapted to removably accept a rigid rod opposite said base, said rod being adapted for insertion into the chuck of a drill.

Abstract: A directing instrument for control of the inclination of the drill post of a drilling apparatus comprising means for sensing the inclination of the post in two directions at right angles to one another. Said means being supported by a holder arranged to be mounted rotatably on said post and so that the axis of rotation of said holder can be set relative to the post dependent on the type of operation to be carried out.

Abstract: A drill sight for visually estimating the angle at which an electric hand drill is oriented relative to the surface drilled, the drill sight is mounted to the top of the electric drill and has a tubular casing with a hollow bore with internal wall markings and with a cross hair at one opening. By projecting a line of sight normal to the surface drilled and through the cross hair to a selected wall marking, the orientation of the drill can be determined.
