A relatively thin, stiff, flat guide line holder or “trig” for accurately supporting and positioning intermediate portions of tautly stretched guide lines such as are used by bricklayers and stone masons in laying courses of bricks, blocks and stones during the erection of masonry walls has a centrally located body portion, and an integrally formed, forwardly projecting guide line support portion. During use, the body portion is positioned atop a flat surface of a wall being erected to support the line holder at a desired height to be met by masonry elements added to the wall, with the support portion projecting forwardly beyond a front surface plane of the wall being erected. Passage formations defined by the support portion open downwardly through a bottom surface of the support portion at two spaced locations along the front surface plane when the line holder is properly positioned. Slot formations defined by the support portion provide a track, or tracks, along which a loop of the guide line can be moved into the passage formations so lengthy portions of the guide line located on opposite sides of the loop can extend along the front surface plane in opposite directions away from the line holder when the guide line is drawn taut at the desired height.
A line holder comprising a one-piece, thin, elongate, generally rectangular member having one end including one end surface defined by the generally rectangular shape of the member, having an opposite end including an opposite end surface defined by the generally rectangular shape of the member and opposite the one end surface, having two side-by-side passages extending through the member at locations spaced short distances from the one end surface of the member, having a single passage extending through the member at a location spaced a short distance from the opposite end surface of the member, having a pair of side-by-side parallel slots each communicating with a different one of the side-by-side passages and opening through the one end surface, and having a single slot communicating with the single passage and opening through the opposite end surface.
A line holder for receiving and supporting a loop of a masonry worker's guide line to position portions of the guide line located on opposite sides of the loop to extend along a linear path at a desired height adjacent a front plane of a wall being erected, comprising a thin, flat, relatively stiff member having a centrally located body portion positionable flatly atop a horizontal surface of the wall at the desired height while being secured in place by placement of a masonry element acting as a weight atop the centrally located body portion, and an integral, forwardly projecting guide line support portion adapted to extend forwardly from the centrally located body and the surface plane 1) to define passage means configured to open downwardly through a bottom surface of the support portion at two side-by-side locations along said path adjacent the front surface plane, and 2) to define slot means communicating with the passages means and configured to permit insertion of the loop into the downwardly opening passage means so the loop is supported by the line holder when the guide line is drawn taut in opposite directions extending along said path, wherein at least a portion of the slot means extends transversely relative to the linear path and wherein at least a portion of the passage means is elongate in a direction along the linear path.
A line holder for accurately positioning an intermediate reach of a mason's guide line used in laying a horizontal row of masonry elements while erecting a wall, comprising a one-piece, stiff, elongate, flat strip having an end region defining two side-by-side passages extending through the strip at locations spaced a relatively short distance from an end surface of the end region, and defining two side-by-side elongate slots each having a slot portion located adjacent to and communicating with a different one of the passages, with the slots extending substantially parallel to each other and in lengthwise directions paralleling the elongate shape of the strip to open through the end surface, and with the passages having widths measured transverse to the lengthwise directions that are greater than are widths of slot portions located adjacent to and communicating with the passages.
A line holder comprising a one-piece stiff, flat, elongate strip having one end and an opposite end defined by the elongate shape of the strip, having two side-by-side passages extending through the strip at locations spaced substantially equidistantly from an end surface at the one end of the strip, wherein the passages each communicate with a different one of two slots extending through a thickness of the strip and in a lengthwise direction relative to the elongate shape of the strip to open through the end surface, wherein the passages are transversely wider relative to the lengthwise direction than are portions of the slots located adjacent to and communicating with the passages.
A line holder for supporting and positioning an intermediate reach of a mason's guide line when drawn taut to extend away from the line holder in opposite directions along a linear path at a desired height adjacent a front surface plane of a wall being built, comprising a thin, stiff, elongate member having a centrally located body portion positionable atop a horizontal surface of the wall at the desired height, and having a guide line support portion formed integrally with and projecting forwardly from the body portion 1) to define passage means opening downwardly through a bottom surface of the support portion at two locations along the linear path within the front surface plane, and 2) to define slot means communicating with the passage means to provide a track along which a loop of the reach can be moved into the passage means to depend through the bottom surface at said locations;
A one-piece line holder formed as a stamping from a thin, stiff, flat, elongate strip of metal, the line holder having a generally elongate rectangular shape defining one and opposite end regions that define one and opposite end surfaces, respectively, that define portions of the perimeter of the generally elongate rectangular shape and extend transversely to the length of the generally elongate rectangular shape, having only two side-by-side passages extending through a thickness of the one end region, having only a single passage extending through a thickness of the opposite end region, with only two slots extending separately through the thickness of the one end region from each of the two side-by-side openings and through the one end surface, and with only one slot extending through the thickness of the opposite end region from the single passage and through the opposite end surface such that the perimeter is interrupted only by the two slots extending through the one end surface and the one slot extending through the opposite end surface.
A line holder for supporting and positioning an intermediate reach of a mason's guide line when drawn taut to extend away from the line holder in opposite directions along a linear path at a desired height adjacent a front surface plane of a wall being built, comprising a thin, stiff, elongate member having a centrally located body portion positionable atop a horizontal surface of the wall at the desired height, and having a guide line support portion formed integrally with and projecting forwardly from the body portion 1) to define passage means opening downwardly through a bottom surface of the support portion at two locations along the linear path within the front surface plane, and 2) to define slot means communicating with the passage means to provide a track along which a loop of the reach can be moved into the passage means to depend through the bottom surface at said locations;
