Abstract: The cylindrical ruler is an elongated, hollow, cylindrical tube of known diameter having an axial slit extending the length of the tube. Indicia defining a circumferential scale are disposed around one end of the tube for measuring the length of an arc. Indicia defining a ruled scale extend lengthwise down the tube adjacent the slit for measuring length and width. Since the tube has a known diameter, it may be used to measure the inner or outer diameter of a pipe, the outer diameter or radius of curvature of a cylindrical lens, etc. The tube may also be used as a drawing tool to draw arcs, circles, or rectilinear lines on a cylindrical object. Preferably, the cylindrical ruler is furnished as a plurality of cylindrical tubes of progressively increasing diameter that can telescope within each other for storage and transport in a protective case.

Abstract: A device for marking a ball includes a stencil ring and a housing. The housing includes a base and a top. The base includes a base quick connecting element. The top includes a top quick connecting element. The base and said top quick connecting elements are for connecting and disconnecting the base to the top. The housing encloses the stencil ring when the base and the top quick connecting elements are connected. The stencil ring includes stencil symbols. The base and the top are sized to hold the ball for marking with the stencil symbols when the base and top quick connecting elements are connected.

Abstract: A tool for tracing a curve from a first plane (such as a wall) onto a second plane perpendicular to the first plane (such as a floor tile) is disclosed. The tool includes a base member having opposite first and second ends with first and second sliders positioned on the base member adjacent the first and second ends, respectively. The sliders are configured to bear against the first plane simultaneously. The tool also includes an arm extending away from the base member with a marking tool positioned at an end of the arm opposite the base member. The marking tool is configured to mark the second plane while the first and second sliders bear against the first plane. The base member is preferably articulated and each of the sliders preferably consist of pairs of coaxially aligned wheels.

Abstract: Pipe cutting templates for marking cutting lines on pipes for subsequent connection to another pipe. A template includes a flexible magnetic sheet having a front surface and a rear magnetized surface for retaining the sheet on the pipe. The sheet has a pair of straight side edges parallel to each other and defining a width of the sheet, the width of the sheet corresponding to the diameter of the pipe such that, during use when the sheet is wrapped around the pipe, the side edges abut. The sheet additionally has a pair of opposed end edges. At least one of the end edges is contoured to serve as a guide for marking the pipe with a cutting line corresponding to the pipe diameter, at least one particular connection type, and at least one particular angle of connection.

Abstract: A scribing system comprising a mounting mechanism, stylus, and force generating mechanism is provided. The mounting mechanism is configured to rotate an elongated object in such a manner that the object is subjected to a bow effect wherein a middle portion of the object bends relative to the end portions of the object. The stylus is for scribing the object at a position x along the long dimension of the object while the mounting mechanism rotates the object. The force generating mechanism is connected to the stylus so that the stylus applies the same constant force to the elongated object regardless of the position x along the long dimension of the object that the stylus is positioned, while the mounting mechanism rotates the object and thereby subjects the object to the bow effect, thereby scribing the object.

Abstract: A tool and method for making precision cuts with conventional saws and other woodworking machines. The shape of an inside or outside corner of a construction, such as a wall construction, is obtained with the tool, and the tool is used to as a guide to set the blade of the cutting apparatus to the proper cutting position. The tool may be used to indicate the miter cuts for both inside and outside wall corners without having to measure the angle with a measuring tool and determine the precise degrees of the angles to be cut.

Abstract: A pipe guide adapter adds marking slots and marking edges to a pipe guide. The pipe guide adapter includes two body sections joined by a hinge enabling the pipe guide adapter to be in open and closed positions. The body sections each include a gripping end and a marking section. The gripping end has a diameter greater than the diameter of the pipe guide to circumferentially grip a portion of the pipe guide in the closed position and to attach to the pipe guide. A pipe is circumferentially gripped jointly by the pipe guide and the pipe guide adapter. A hinge pin is partially disposed in the hinge and extends beyond the hinge. The hinge pin allows tie pipe guide adapter to be aligned to the pipe guide. The extended portion of the hinge pin acts as a stop and a spacer between the pipe guide adapter and the pipe guide.

Abstract: A tool for scribing a longitudinal groove on an elongate cylindrical rod suitable for implanting as a prosthetic in a living being supports the rod in a linear groove on a bed of a frame of the tool. A track is mounted on the frame and runs parallel to the groove. A carrier mounted on the track can slide on the track in constant spaced relation to and along the groove. A scribe mounted on the carrier extends toward the groove to contact a rod in the predetermined position. A preferred version of the tool has a clamp mounted on the bed for clamping the rod in the predetermined position. Additional features allow for precise angular positioning of the rod and for scribing a dashed line on the rod. In use, the tool operator places the rod in the predetermined position in the groove. The scribe is then pressed into contact with the rod. While the scribe is in pressed contact with the rod, the operator slides the carrier along the track.
