Patented Nov. 24, 1953 ADJUSTABLE LINE JIG FOR LAYING BRICK AND CONCRETE BLOCK WALLS Fred W. Patzel, Lincoln, Nebr. Application April 6, 1951, Serial No. 219,607

2 Claims. (01. 33-86) This invention relates to masons implements, and more particularly, to an improved jig for holding a masons line as employed by bricklayers and other mechanics in laying brick or concrete block walls.

A main object of the invention is to provide a novel and improved masons line jig which is simple in construction, which is easy to use, and which provides uniform spacing between the line and the wall with which it is used.

A further object of the invention is to provide an improved line jig for use in laying brick or concrete walls, said jig being inexpensive to manufacture, involving simple parts, being easy to adjust in accordance with difierent sizes of blocks employed for walls, and providing a secure and accurate holding means for the masons line.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

Figure 1 is a perspective view of a portion of a block wall on which is engaged an improved masons line jig according to the present invention;

Figure 2 is a top plan view of the line jig of Figure 1;

Figure 3 is a cross-sectional view taken on the line 3-3 of Figure 2.

In the laying of brick or concrete block walls by a mason, it is necessary for him to lay what is known to the trade as a corner lead from the two corners of the wall, which is done by a line jig. From these corner leads a line is stretched to guide the mason in laying a straight wall. The line jig customarily used is a straight spike or pin which is driven into the mortar between the corner blocks. If the line is drawn too tight, the mortar will break and cause the line to sag, which makes it difficult to lay a straight wall. Also, in order to lay a straight wall, it is desirable to provide a small space between the line and the wall. With the pin or spike driven into the mortar, it is difficult to have uniform spacing between the line and the wall along the length of the line.

The adjustable line jig of the present invention may be used when laying the wall either from the outside or the inside. The jig is adjustable to any size of wall.

Referring to the drawings, the improved line jig is designated generally as H and comprises an elongated main body I 2, which may be a metal bar' formed adjacent one end with a downwardly offset portion l3 and with a depending arm I extending at right angles to the oifset portion I3, as shown in Figure 3. The corner defined by portion l3 and arm I4 is formed with an outwardly extending, upwardly inclined lug I5 of substantial length which is employed for securing the end of the masons line, as shown in Figure 1. The end of arm M is formed with a flange l6 extending at right angles to the main portion of arm l4 and extending parallel to the portion l3 of main body I2.

Designated at I! is a right-angled plate member having a body portion l8 and an arm l9 extending at right angles thereto. The main body I2 is formed with uniformly spaced holes 20 and the element |8 of plate I! is formed with threaded openings 2|, 2| spaced apart the same distance as the openings 20. Designated at 22, 22 are respective studs which are threadedly engageable in the openings 2|, 2| and which are adapted to extend through a selected pair of openings 20 of the body l2 and are provided with

respective wing nuts

23, 23 for clamping the plate member I! to main body |2 in the manner shown in Figure 3.

In using the jig, the plate member I8 is secured to the main body |2 in an adjusted position, wherein the block of the wall being laid shown at 24, may be received between the arm I9 and the edge of flange l6, as shown in Figure 1. The jig device is engaged over the block in the manner shown in Figure 1, with the lug l5 projecting upwardly and outwardly. The line, shown at 25, is tied to the lug l5 and engaged beneath the corner defined between element I3 and arm I 4, said corner being formed at its inner side with a groove 26 in which line 24 is receivable. A similar jig is employed at the opposite corner of the wall or at a substantial distance from the first jig, whereby the line 25 is stretched between the two jigs. The tension of the line 25 exerts a torque on the jigs which causes the jigs to rotate slightly and to become anchored to the blocks on which they are engaged, whereby the jigs are held firmly in place. The flange l6 on each jig provides uniform spacing of the respective arms I 4 of the jigs, and also provides uniform spacing of the line 25 from the wall at all points along the line. As each row of blocks is laid, the

jig devices may be readily moved onto the blocks of the next row.

While a specific embodiment of an improved masons line jig has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claims.

What is claimed is:

l. A masons line jig comprising an elongated flat main body, a first armcoextensive in width with said main body projecting from one end of said main body at right angles thereto, a lug element projecting obliquely outwardly from said end of the main body oppositesaid'arm'and'coextensive in width therewith, a second arm projecting from the intermediate portion of said main body parallel to and substantially equalin width" to said first arm, and an inwardly projecting rectangular flange on the end of and equal in width to said first arm and projecting parallel to said main body toward said second arm.

I 2. A-masons line jig comprising an elongated flat body, a first arm coextensive in width with said main body projecting from one end of said main body at right angles thereto, a lug element projecting obliquely outwardly from said end of said main body opposite said arm and coextensive in width therewith, a second arm adjustably secured to the intermediate portion of said main body, said second arm being substantially equal in width to and projecting from the intermediate portion of said main body parallel to said first arm, and an inwardly projecting rectangular flange on the end of and equal in width to said first arm projecting parallel to said main body toward said second arm, said first arm being formed at its inner surface adjacent the main body with a transverse groove adapted to receive a masons line secured to said lug element.
