IMPROVEMENT IN BRICK-LAYERS POINTERS.

Specification forming part of Letters Patent No. 138,911, dated May 13, 1873 application filed October 7, 1872.

To all whom it may concern.-

Be it known that I, JOSEPH S. MERRIKEN, of Baltimore, in the county of Baltimore and in the State of Maryland, have invented certain new and useful Improvements in Brick-Layers Pointer; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyin g drawing and to the letters of reference marked thereon making a part of this specification. l

The nature of my invention consists in the construction and arrangement ofabrick-layers pointer for pointin g or finishing off the mortar between the bricks, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which Figure l is a perspective view, and Fig. 2 a bottom view, of my invention.

A represents the holder, which is made of cast-iron, substantially as shown, forming, at one end, the handle B. The holder proper is provided with two mortises or openings, a a, for the reception of the rollers O O, which are pivoted in the same by means of pins or rods b 11 passing through the holder and through central holes in the rollers.- These rollers are made of such size andso arranged in the mortises a a that they will project very slightly beyond the under surface of the holder A. Around the center of each roller 0 is a flange, d, having a curved circumferential groove, as shown. The under side of the holder A may be grooved on a line with said flanges d d to prevent the mortar from adhering to the same. Between the rollers G C, from each side of the holder inward, is made a dovetailed groove for the insertion of a brush, D. These brushes do not meet in the center, but leave a vacant space at least equal to, if not a trifle wider than, the flanges d d.

With this machine the brick-layer can easily finish off the mortar between the bricks by placing the flanges d d of the rollers O G between the bricks and moving the device in either direction. These flanges will then form a perfect bead of the mortar, and the brushes D D will remove any mortar that might be on the surface of the bricks. There being one rollerin front and another in rear of the brushes, it will be seen that if the brushes should, by any means, scrape the mortar, the roller following behind will finish it off again.

In door-jambs or other similar places the machine is turned around and only the outer roller used, the holder at the outer end being contracted in thickness, so that this roller will project as far on the upper side as it does on the under side. In either case the body of the roller or rollers moves on the brick while the flanges are between the brick.

The rollers G C can readily be removed and others substituted having wider or narrower flanges, according to the kind of work being 3. The roller 0, provided with a circumferentially-grooved flange, (1, around its center, and arranged in a suitable holder, substantially as and for the purposes herein set forth.

4.. The combination of the holder A with handle B, rollers 0 O with flanges d d, and brushes D D, all constructed and arranged substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 26th day of September, 1872.
