FRED H. ACKERSON, OF WICHITA, KANSAS.

BBICK-MASONS JOINT BAKER AND SMOOTHER.

Specification of Letters Patent.

Patented J an. 28, 1919.

Application filed May 6, 1918. Serial No. 232,929.

To all whom it may concern: I

Be it known that I, FRED H. AoKERsoN, a citizen of the United States, and a resident of Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Brick-Masons Joint Bakers and Smoothers, of which the following is a description, referring to the accompanying drawings, which form a part of this specification.

In the invention, an instrument or holder is adapted to receive interchangeable tools, each tool being suited for raking out the mortar in the joints of a brick wall to a desired depth and at the same time smoothing the face of the mortar joint to conform to a finish or design such as might be specified.

In the drawings, Figure 1 represents a top View of the holder and allied tool combined therewith. Fig. 2 is a side view of Fig. 1. Fig. 3 is an end view of Fig. 1 looking in the direction of the arrow. Fig. 4 shows the composite tool in operative position upon a brick wall. Fig. 5 is a sectional view of a brick wall showing some of the various groovings of the mortar joints; opposite each of said mortar joints is shown the tool, in front and side views, adapted for finishing said joint.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings. Referring to the drawings, Fig.

1 shows the holder comprising a handle 10 and a forked bar 11 integrally connected at 12 the base of said forked bar. The outer ends 13, 13 of the bar 11 are connected by a cross bar 14. This cross bar 14 has a hole 15 drilled through same from top to bottom thereof and located midway between the ends 13, 13 of the forked bar. The under side of the hole 15 is enlarged at 16 to provide a recess to receive a nut for the purposes further described. It will be further observed that the forked bar 11 is bent at 17, 17 intermediate its ends 13, 13 and its connection 12 with the handle 10 whereby the outer portions 13, 17-13, 17 form runners 18, 18 depressed to a plane substantially parallel with the plane of the handle 10. By reference to Fig. 4 it will be seen that these runners 18, 18 are adapted to stagger the mortar joint and contact with the two bricks 20, 20 so that the hole 15 points directly toward the mortar joint 19. The handle 10 as will be seen is away from the brick surface a proper distance so that the mason can grasp same and draw the composite tool along the face of the wall in the position illustrated.

By means of the various tools illustrated in the drawings any desired grooving or finish may be obtained for the mortar joint. The tool consists, first, of a finishing portion 21 of the desired shape to produce the specified joint; for instance, in the series of tools, 21 is convex to produce the concave joint 19*. Tool 21 shown in front and side views produces the V-shaped mortar joint 19". Tool 21 shown in front and side views produces the mortar joint 19. Tool 21 produces the convex joint 19*. The joints 19, 19, 19 and 19 are surface joints, while the joint 19 produced by the tool 21 is a recessed joint of any desired depth. All the above described tools are rounded along their operative face edge as seen at 23 and in the various side views of the tools at 23", 23, 23 and 23*, this permits of a smoothing effect to be given to the joint as the tool moves over same. The tool seen at 21, in front and side views, will produce the recessed joint 19 but itwill be a rough raked joint since the surface of the tool 21 is provided with corners adapted to rough up the mortar in contradistinction to the smoothing out of the joint obtained by the curving surface 23 of 21.

Each tool of the series 21 is provided with a threaded shank 24, and a nut 25 is adapted to be screwed thereon, then the upper portion of the shank 24 is passed upwardly through the hole 15 in the cross bar 14 of the holder until the nut 25 engages within the recess 16 provided in the under side of the cross bar 14. The adjustment which de termines the depth that the joint will be raked is made by screwing the nut 25 up or down on the shank 24 and then securing the tool to the cross bar by means of the upper thumb nut 26 which is screwed down on the upper portion of the shank 24 to a contact with the upper face of the cross bar 14. This as will be readily understood by reference to Fig. 4 will move the finishing head 21 of a tool at right angles to the plane of contact of the runners 18, 18 and brick 20, 20 to obtain the desired depth of the grooving such as is illustrated in Fig. 5.

For inside corners and other inaccessible places, a special rake or hook 27 is provided at the outer end of the handle 10. This rake 27 Would be preferably faced at 28 to conform to the shape of the tool 21.

Such modifications may be employed as lie Within the scope of theappended claim.

Having fully described my invention, What I noW claim as new and desire to secure by Letters Patent is:

In combination in a brick masons joint raker, a holder having a handle integral With the base of a forked bar, the outer ends of said bar being bent to form paired runners integrally connected by a crossbar, a hole centrally located in said cross bar at right angles to the plane of the base of said paired runners; and-a tool having a finishing face of suitable configuration for the specified purposes and a threaded shank portion integral With said face portion, a nut adjustably screwed thereon, the upper end of-said shank-being adapted to enter the hole in said cross bar of the holder from the under side so that said adjustable nut shall contact said cross bar, and a nut adapted to b'e screwed down on said upper shank portion to contact said cross bar and secure said tool in operative position as specified.
