MORTAR-JOINT BAKER AND FIN ISI-IER.

Specification of Letters Patent.

Patented July 22, 1919.

Application filed January '7, 1919. Serial No. 269,993.

To all whom it may concern:

Be it known that we, THORWAIJD THORSON and FRED M. ELLnn, citizens of the United States, residing, respectively, at Forest City and Ames, in the counties of Winnebago and Story, State of Iowa, have invented a new and useful Mortar-Joint Baker and Finisher, of which the following is a specification.

It is the object of this invention to provide a simple tool adapted to be used for finishing mortar joints, the tool being adapted to be operated either by a push or by a pull.

It is within the province of the disclosure to improve generally and to enhance devices of that type to which the invention appertains.

\Vith the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shoWn can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in elevation, a tool constructed in accordance with the invention; Fig. 2 is an elevation wherein the tool is viewed at right angles to the showing of Fig. 1; and Figs. 3, 4, 5, 6 and 7 are elevations showing the various applications of the tool.

The device forming the subject matter of this application preferably is made of metal what wider than the bit 6. The ends 9 of the bits 6 and 7 converge toward the ends of the handle 1 to form inner cutting edges 10 and outer cutting edges 11, extremities of the parts 2 and 3 of the handle being beveled off flush with the outer inclined ends of the bits, as indicated at 25. The longitudinal or working edges of the bits are convexed as shown at 12. It will be understood that, so far as cross section is concerned, the working edges of the bits may be shaped in various ways, depending upon the shape which it is desired to impart to the mortar groove. This detail, however, is a mere matter of design and need notbe shown or described. The handle 1 is provided with openings let located near to the inner cutting edges 10, the handle being beveled along the edges of the openings 14, as indicated at 26, to correspond with the adjacent inclined end 9 of the bits 6 and 7.

As shown at 3, either of the bits may be pushed along a mortar groove, to raise the material, the tool operating as a plow. If desired, the tool may be operated by a pull, as shown in Fig. 1, whereupon the inner cutting edge 10 will be effective, the mortar riding outwardly through the opening 14. As shown in Fig. 5, the tool may be pushed or pulled, the converted edge 12 of the bit servingto smooth down the bottom of the mortar groove. In Fig. 6, the tool is shown as being pulled backwardly in a mortar groove, whereupon the outer cutting edge 11 will deepen the groove, as shown at 15. Fig. 7 discloses the fact that the outer cutting edge 11 of the bit may work closely into an angle as shown at 16.

Since the bits are tongue and grooved to the ends of the handle 1, each bit may be held in place by asingle securing element such as the screw 8. The bits 6 and 7 may be removed at any time, and be replaced by others of like or similar construction.

Having thus described the invention, what is claimed is 1. A tool of the class described comprising a handle, and a bit carried by one end of the handle, the ends of the bit converging toward the handle to define inner and outer cutting edges, the handle having an opening located adjacent to the inner cutting edge.

2. A tool of the class described, comprising a handle and a bit carried by the end of the handle, the end of the bit converging as our own, we have hereto affixed our signatoward the handle to define inner and outer tures in the presence of two Witnesses. cutting edges, the handle having an opening THORWALD THORSON. located adjacent to the inner cutting edge, FRED M.
