Tubular lineation tool

Abstract

A tubular lineation tool comprising of a concave adaptor member, defined by a U-shaped profile having a pair of terminal ends, a pair of rectangular baseplate members, which serve as horizontal supports, securely affixed to the lower outer edges of the concave adaptor’s terminal ends, a line guide member, fixedly mounted at the central upper curvature of the concave adaptor member, said line guide member having a central hole, which serves as a means to securely retain a marking instrument through insertion into the said central hole. Generally, most lineation tools are conventionally used on flat surfaces, making it  difficult to achieve precise marking of reference lines on cylindrical workpieces such as pipes and tubes. The objective of the utility model is to provide a tubular lineation tool that facilitates marking of reference lines on cylindrical workpieces, such as pipes or tubes, by guiding a marking instrument.

Said limitation often results in misaligned cuts, uneven layouts in fabrication andconstruction. In this regard, reference is made to patent no. 2834116A to William T.Hambrick. This patent describes a tool that attaches to a carpenter's square to facilitatethe centering and marking of pipes.The primary object of the utility model is to provide a tubular lineation tool formarking reference lines on cylindrical workpieces such as pipes or tubes.Another object is to provide a tubular lineation tool that is durable and easy tomanufacture.For a better understanding of the utility model, its operating advantages, and thespecific objects attained by its use, reference should be made upon the followingsystematic description, taken in concurrence with the affixed drawings, which illustratethe preferred embodiment of the utility model.Brief Description of the Several Views of the DrawingsTo facilitate understanding, reference will be made to the herein below describedfigures, in which:Figure | is a front perspective view of the tubular lineation tool.2Figure 2 is a perspective view of the tubular lineation tool.Figure 3 is a right perspective view of the tubular lineation tool in positionagainst a cylindrical workpiece, such as a pipe or tube.Detailed DescriptionWith orientations to the different views of the drawings, the present tubularlineation tool includes a concave adaptor member 1, defined by a U-shaped profilehaving a pair of terminal ends, which serves as a mechanism to accommodate acylindrical workpiece, such as a pipe or tube; a pair of rectangular baseplate members 2,securely affixed to the lower outer edges of the concave adaptor’s terminal ends, whichserve as horizontal supports; a line guide member 3, defined by a U-shaped exteriorprofile, fixedly mounted at the central upper curvature of the concave adaptor member,said line guide member 3 having a central hole 4, which serves as a means to securelyretain a marking instrument, such as a pen or pencil, through insertion of the saidmarking instrument into the said central hole.As the concave adaptor member | of the said tubular lineation tool is positionedagainst the curved surface of the cylindrical workpiece, the rectangular baseplatemembers 2 are positioned on a flat surface to provide stability to prevent tilting orshifting as the tubular lineation tool is moved along the cylindrical workpiece's length; amarking instrument, such as a pen or pencil, is inserted into the central hole 4 of the lineguide member 3, which securely retains the marking instrument while the tubularlineation tool moves along the cylindrical workpiece; the said line guide memberensures continuous contact between the marking instrument and the cylindricalworkpiece, maintaining a fixed orientation parallel to the surface of the cylindricalworkpiece and guiding the marking instrument in marking reference lines.Consequently, this results in a tubular lineation tool that facilitates marking of referenceGYMO56Y17YO20251QZ 17 May 2025 03:03:34 PM 3Description. pdflines on cylindrical workpieces, such as pipes or tubes, by guiding a markinginstrument.GYMO56Y17YO20251QZ 17 May 2025 03:03:34 PMDescription. pdf
