BRICKLAYER'S MORTAR JOINT TOOL Filed Dec. 1, 1959 ,0 Paul R Eldridge, J;

3,109,189 BRICKLAYERS MGRTAR EGINT T001. Paul R. Eldridge, Jr., Harlingen, Tern, assignor to Ba 30 Sales Company, Inc., a corporation of Texas Filed Dec. 1, 1959, Ser. No. 856,492 4 Claims. (Cl. 15-1055) This invention relates to a bricklayers tool and more particularly to a tool combining a concave joiner and a ra-ker.

An object of the invention is to provide a multiple tool adapted to be used by bricklayers. A tool in accordance with the invention combines a concave joiner and raker with one providing a handle for the other.

Another object of the invention is to provide a tool which embodies a number of advanced features in a tool for bricklayers.

An important feature of the invention is found in the arrangement of parts from which the raker is constructed. In forming certain types of joints an appreciable quantity of mortar must be removed at the faces of the bricks. A tool in accordance with the invention provides an outlet for this mortar when raking the underside of the upper bricks in a course. The joints in brickwork are of different sizes because of the different heights of brickwork that must be reached. Therefore, the only way to reach a certain height is by the ditferent thicknesses of the joints, making it necessary to touch the upper as well as the lower bricks in a single course in order to make a clean joint. If there is no outlet for this mortar which is being removed, the soft mortar gets under an ordinary raker and smears the brickwork. This is especially undesired when the bricks have a mat face surface.

Another important feature of the invention is found in the arrangement of the scraping attachments. They are made such that they can be trimmed to restore a square edge thereon. Constant scraping of the tool against the brick for the purpose of obtaining a clean and uniform joint causes the raker attachment to wear in the form of a point. This cannot be helped since it is normal attrition for a raker. However, by restoring the raker attachment,i.e., clipping off the pointed end, the useful life of the raker is materially prolonged.

One of the great advantages of this invention is found in its versatility. All conventional types of joints may be formed. Another meat advantage and of equal importance is the convenience which the tool affords. It is so designed that the raker section functions as the handle for the concave joiner and alternatively, the joiner functions as the handle for the raker section. The raker section is so designed that practically all conventional joints may be formed with the tool.

Another important feature of the invention is found in the actual construction, considering it from a cost standpoint. This tool may be made very inexpensively and yet, it combines the functions of numerous individual tools.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 11 is a fragmentary top view of the tool.

In the accompanying drawings there is an illustration of a multiple tool it} which constitutes one possible embodiment of the invention. The tool is is made in two main sections 12 and 14- with the section 12 constituting a concave joiner and the section 14- forming a raker. The sections are joined together by means of a flat connecting member 16 arranged in a plane at approximately 45 de grees to the

planes containing sections

12 and 14 The purpose of this is to allow suilicient leverage for the user, inasmuch as the section 12 functions as a handle for section 14, and section 14 functions as a handle for section 2 (compare FIGURES 3 and 5).

Section 12 is a concave joiner. The entire tool is made of a single piece of metal and therefore, the sections are constituted by formation of the metal into the desired shapes. The concave joiner is approximately semi-circular in cross section and is elongate. The end 2% of the joiner (FIGURE 10) is out or otherwise formed at an angle of about 30 degrees to a transverse plane passed through the joiner at right angle to the longitudinal axis thereof.

Section 14 is of rather simple construction. It is made of a flat plate 22 joined at the rear edge 24 thereof integrally with connecting member 16. The plate 22 is approximately rectangular when viewed from above (FIGURE 2) and has two side edges 20 and 30 together with an outer edge 32. Edge 24 is integrally joined, as aforesaid, with connecting member 16.

A striker attachment or member 34 is formed integrally with edge 32 and extends forwardly and upwardly therefrom at an angle of approximately 45 degrees to the plane of plate 22. Attachment or member 36 extends downwardly from the plane of plate 22 and is made of an essentially rectangular strip 3-3 of considerable length in comparison to previous rakers, joined to plate 22 by means of an offset forming member 49. The offset forming member is arranged at approximately 45 degrees to the plane of plate 22 and also to the plane of member 38. The location of member 36 is of importance. It is formed along edge 2% but terminates short of the edge 42 of an opening 44. The opening is formed by a cut-out in plate 22 between edges 32, 2'8 and 24 thereof. This opening is of considerable importance for the reasons pointed out above.

in use, the edge 28 and a portion of the plate adjacent to edge 28 may be used to form a trowelled joint 6% (FIGURE 9) by holding section 12 and pulling the tool in the usual manner. Concave joints 62 (FIGURES 3 and 4) are formed by holding section 14 and pulling the joiner section across the mortar between courses of brick. This, of course, applies wh ther the joints are ver tical, horizontal or at any angle. The usual arrangement is to have the joints. vertical and horizontal, although there is nothing to prevent the tool from being used in unusual situations. Notice that section 12. has the working surface facing oppositely from the w, rking surfaces of section 14. This cooperates with the angular connecting member is so that the sections are ofiset -from each other providing leverage for correct use of the tool. Attachment 3 (FIGURES 7 and 8) is used to remove excess mortar from the joints such as at 64. The attachment or strip 35 is then used (either horizontial or vertical) to rake out the mortar to a greater depth, While the undersurface of plate 22 rests on the face 6t; (FIG- URE 6) of the bricks while joint 7% is being formed. As joint 79 is being formed it is to be noted that opening 44, especially at edge 4-2 directly in front of the end of strip 38, serves an. important function. This is so that the loose mortar may be discharged Without acculating beneath the tool and smearing the adjacent bricks.

In forming joints, strip 33 has a tendency to wear to a point 72 (FIGURE 11) as shown in dotted lines. When this happens, the point 72 may be snipped oil or otherwise out off along line 74 thereby restoring the right angular edge of strip 38.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling Within the scope of the invention as claimed. For example, although the term brick is used herein, it is to be clearly understood that this is merely one type or" masonry. There are many others including tile, block of all types, etc. with which the tool may be used.
