8 Claims.

of the plaster right up into the corner without the end oi the tool digging into the plastered of the invention will be made apparent in thev course of the following detailed specication, reference being had to the accompanying drawing wherein:

Fig. 1 is a plan view of my improved tool.

Fig. 2 is a side or edge view of my tool.

Fig. 3 is an end View, a4 part of the handle being shown broken away and in cross section to disclose the mounting of one of the brace rods therein.

Referring now with more particularity to the drawing, my tool comprises the rectangular, flat base plate 5 upon which is mounted a handle 5 extended longitudinally on the base. This handle 6 is of the usual type and shape used on plasterers iioats and includes the downwardly turned ends 'l which are secured by flat head screws 8 (or other suitable means) to the base. Along one margin of the base a side flange 9 is turned upwardly at right angles as shown, forming a sharp angle I l) at its junction with the base. This side nange is braced against the action of lateral stresses by means of the brace rods l|-,|2 which are secured, as by welding at I3, to the inner side of the side flange and which extendl inwardly therefrom parallel with the base 5 and penetrate the ends 'l of the handle 45 '6. These handle ends 1 have transversely eX- tended bores i4 which receive and pass the inner ends of the brace rods H-IZ and these bores are enlarged on the sides remote from the side flange 9 to form sockets I5 wherein are mounted 50 the screw type plugs I6. The inner ends of the brace rods lI--lZ are threaded as at I1 and the plugs I6 are screwed thereon and drawn tight in the sockets I5. As a result, the brace rods Il-IZ are rigidly supported and the side ange 55 9 is so connected and supported by the handle 6 that no iiexingor weaving action of the flange can take placel under any circumstances.

While it is considered that the base 5 and the sideflange 9" are preferably made integrally of one piece of tempered steel, since it has been 5 found that only this material has vthe requisite wearing qualities for a tool of this kind, nevertheless the 'base and flange may be formed separately, and of different materials, ii foundk expedient, and the two elements then riveted l0 or otherwise secured together. Heretofore, such materials as wood and aluminum have been employed but these wear very rapidly inv use and after 'a short time the corner at the working edge of the't'ool is `worn away to the point that 35 a clean angle or corner can no longer be formed in the plaster. The use of steel is further recommended ior the reason that this material has no tendency to stain the plaster.v

' The useof steel for floats of this kind has 20 not hitherto been possible since-it, of course,

' has at least a measure lof fiexibility and, consequently, the edge of theoat. would have a tendency to flex and thus prevent the proper use of the tool in a corner. However, my invention 25 provides the brace rods Il-I2 which positively brace and support the side flange of the tool and permit the use of this desirable material. The iiexibility and resiliency of the steel used is actually put vto an advantageous use in my 3o invention. It will be noted that a substantial lateral portion oi' the base 5 opposite to the side flange 9 is entirely free and unsupported insofar as the handle Ev is concerned. As a result this portion of the base 5 may bend and 35 l iiex as may be necessary in use and in order to prevent its digging into a wall or ceiling surface While working in the adjacentcorner.

Referring to Figure 1,l it will be noted that the side flange 9 is bent slightly and stands out- 40 wardly from a 'straight line at its center I8. The opposite end portions of the side ange thus angle inwardlyffrom the straight line as shown, and when either of these end portions is rested against an adjacent Wall while trowelling the corner, the opposite end portion will stand outwardly from the Wall a substantial distance. Therefore, by so manipulating the device that the trailing end of the side flange 9 engages the wall (or ceiling) the opposite frontal end will stand away and cannot dig into the plaster. This action greatly facilitates the proper working of the plaster to an even line and clear up into the corner.

As a further aid to thus preventing the marring of the plaster by the frontal or leading edge of the tool, the ends of the side flange 9 are beveled off from their free margins toward the base as indicated at I9.

It is understood that I may make changes in the structure and assembly herein specified, provided that such changes fall within the spirit and the scope of the appended claims.

Having thus completely disclosed my invention, what I claim as new and desire to secure by Letters Patent is:

1. A plasterers float and angle trowel comprising a flat base, a ilange turned upwardly along one lateral margin of the base, a handle secured to the base, and rods extended between the flange and the handle and effective to rigidify the said flange.

2. A plasterers tool comprising a base member of llexible material, a ilange formed integrally with the base member and turned at right angles along one side thereof, a handle secured to the base parallel with the ilange, and rods extended between the flange and the handle.

3. A plasterers tool comprising a brace member, a flange formed integrally with the base member and turned at right angles along one lateral margin of the base, a handle secured to the base parallel with the said flange and in spaced relation thereto, and rods secured between the ange and handle and extended parallel with and above the plane of the hase.

4. A plasterers tool comprising a -fiat rectilinear base member, a flange formed integrally with lie base member and turned upwardly at right angles along one margin of the same, a handle secured to the base parallel with the ilange and spaced from the opposite margin of the base member to permit flexing action of that portion of the base member, and. means connecting the flanged portion of the base to the handle in a rigid manner.

5. A plasterers tool comprising a flat and rectangular base, a flange turned upwardly at right angles along one lateral margin of the base, and the said flange being formed of angularly extending faces meeting at a point of maximum width of base toward its center.

6. A plasterers tool comprising a flat and rectangular base having a flange turned at right angles along one lateral margin, the said flange being formed of inclined -faces, the base tapering from the intersection of the faces toward the ends, whereby one portion of the flange may be brought into contact straightly with a wall while the opposite end stands outwardly therefrom.

7. A plasterers tool comprising a flat rectangular base and a flange turned upwardly along one lateral margin oi the base, the said flange being bent medially to stand outwardly from the base and to extend at opposite gradual angles from said medial portion, and the ends of the flange being beveled oil to the base.

8. A plasterers tool according to claim 6, wherein the base is of flexible metal, a handle on the same side of said base as said flange, and rod means above the base extending from the ilange to said handle.
