  • Patent number: 11415400
    Abstract: An example combination tool for marking, measuring, and checking level includes a holder for a marking device (e.g., a soapstone). The holder has a body formed by a first side, a second side, a front side, a back side a top side, and a flat bottom side. A securement releasably secures the marking device at least partially within the body. Turning the securement in a first direction tightens the marking device within the body of the holder. Turning the securement in a second direction loosens the marking device in the body of the holder so that the marking device slides in and out through an opening formed in the front side of the body to adjust a position of the marking device for use in marking. The example combination tool may also include measuring markings, a level, a clip, and a grip.

  • Patent number: 7775899
    Abstract: The present invention helps golfers consistently execute the ideal golf swing. To consistently execute the ideal swing, golfers must consistently align the shafts of their clubs at the ideal angle with respect to the horizontal at setup, prior to executing the swing. The present invention helps golfers set their clubs at the ideal angle by attaching an angle indicating device to the club that indicates the angle of the club with respect to the horizontal. The preferred embodiment of the angle indicating device is a small, lightweight circular bubble level, that has angle markings around its edge, and quickly clips onto an off of the golf club. The angle indicating device is sufficiently small and lightweight that it does not affect the golfers swing. The same device may be used on different golf clubs to show the desired angle for the club in use.

The arm supports at one end a gripping mechanism, such as a bar, that extends outwardly in parallel to the axis of rotation about which the arm pivots. A spring extends between the arm and the mounting mechanism. To attach the level to a structural component a user pivots the arm to draw the gripping bar away from the level. The user then positions the level and the gripper bar on opposite surfaces of the structural component, and releases the arm. The spring draws the arm against one surface of the structural component and holds it in position, to clamp the level to the opposing surface of the structural component. The mounting mechanism may include a pivotally mounted bracket that pivots about a second axis of rotation. The bracket pivots the arm 90.degree.

  • Patent number: 4829676
    Abstract: A level indicating device comprising a level having attached thereto a pair of detachable securing clips whereby the level indicating device can be maintained mounted flush with a structural member in any spatial orientation without further manual manipulation. The level has clip receiving slots formed in the opposed ends thereof adapted for force-fit reception of the detachable securing clips. The detachable securing clips have mirror-image symmetry and comprise a transverse segment adapted to be force fit inserted into the clip receiving slots, a pair of opposed leg segments extending from opposed ends of the transverse segment for elastically engaging the outer peripheral surface of the structural member to maintain the level indicating device flush with the structural member, and curved end segments terminating the opposed leg segments.

  • Patent number: 4733475
    Abstract: An extension level apparatus suitable for use with a carpenter's level includes in combination a pair of elongated frame members adapted to receive therein the carpenter's level and also includes a spring loaded extension member which permits the extension level to be retained in a wall opening into which a door is to be inserted. The extension level permits the user thereof to determine rapidly the exact vertical position of one vertical edge of the door jamb, allowing for shimming where necessary, and permits a measurement to be taken from a starting point to an end point where the second edge of the door opening is to occur. Hereagain the vertical alignment may be rapidly obtained with the use of shimming when necessary, thereby permitting the door jambs to be inserted rapidly and with accuracy.

  • Patent number: 4400889
    Abstract: A dial-type clinometer is fixed to a vise-type pliers-like clamp to position its indicator for swinging in a vertical plane which is substantially perpendicular to the pivot of, and which substantially symmetrically bisects, the clamp. At least one of the jaws of the clamp is adapted for insertion into the end of a pipe that is held horizontally in a pipe-bender preparatory to bending of the pipe in a vertical plane. The clamp is so positioned that when the jaws are locked closed upon the pipe wall, the dial of the clinometer will lie in a vertical plane close to the axis of the pipe. After the dial is set to zero, the pipe is bent until the dial index shows the number of degrees of bend desired. The clamp also has a second pair of jaws extending parallel to its pivot for fastening the clinometer with its axis parallel to the axis of the pipe before its removal from the bender, so that the pipe can be removed and replaced in the bender (rotated 180.degree.

  • Patent number: 4066232
    Abstract: A device consisting of a rectangular shell affixed to a spring-type clamp for securement thereof onto a convenient location on a scaffolding or mortar board, the rectangular shell used for holding level in a convenient but safe location for use by construction workers, such as bricklayers, masons, and the like, when performing construction tasks, or for use in storing a level when not in use. The level is inserted through the open end of the rectangular shell, the level thus being maintained in a safe and out of the way location, with the spring-type clamp affixed to a desired surface, including a scaffolding, mortar board, home work bench, or the like.
