F. WICKHAM MASONS TOOL Filed Nov. 13 1922 Patented Sept. 23, 1924.

UNITED STATES FRANK L. WICKHAM, O'F LENNON, MICHIGAN.

MASONS 'IOOL.

Application filed November 13, 1922.

To all whom it may concern; 7

Be it known that I, FRANK L. VVIOKHAM, a citizen of the United States, residing at Lennon, in the county of Genesee and State of Michigan, have invented certain new and useful Improvements in Masons Tools, of which the following is a specification.

This invention relates to an improved tool for use in connection with certain trades, such as stone masons, brick masons, and the like, in the spreading, shaping, and smoothing of plastic materials.

A further and important object of this invention is the provision of an improved tool embodying a trowel arrangement, and

i a shaping member adjustably associated therewith.

A further object of this invention is the provision of an improved tool of the above mentioned character, which may be utilized for the quick and efficient performance of work by stone or brick masons, in the pointing, beading, jointing, and tucking of various classes of work.

Other objects and advantages of this invention will, of course, be apparent during the course of the following detailed description.

In the accompanying drawing, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views.

Figure 1 is a side elevation of the improved tool, showing the parts thereof in operative relation.

Figure 2 is a plan view of the trowel arrangement of the improved tool.

Figure 3 is a transverse cross sectional view, taken through a portion of the improved tool.

Figure l is a fragmentary view, partly in section, showing the manner in which the improved tool may be successfully used in conjunction with the shaping or beading of r plastic material at the joint of walls and like structures.

In the drawing, wherein for the purpose of illustration is shown but the preferred embodiment of this invention, the letter A generically indicates the improved tool, which may embody the trowel arrangement B, and improved oint shaping tool C.

Referring to the trowel arrangement B, the same preferably comprises the flat sub 5 stantially V-shaped blade 10, the side mar- Serial No. 600,753.

ginal edges 11 of which are disposed in con verging relation toward the pointing tips 12. A handle 15 is provided, preferably being formed rigid or integral therewith with blade 10, including the upwardly inclined hand engaging portion 16, relatively broader than/thick, to provide a convenient grasp for the operator in order to facilitate use of the tool. A hooked end portion 17 is preferably formed at the rear end of the handle portion 16, being reduced with respect thereto, and preferably circular in cross section. This hook shaped portion 17 preferably includes the arcuate or curved part 19, which extends upwardly above the handle portion 16, and the straight line portion 20, the axis of which is parallel to blade 10, and having a tapered surface which gradually converges to a point 21, the portion 20 being disposed upwardly of the handle portion 16 to-pro vide a suflicient space intermediate the same and the hand engaging portion 16 to accommodate the hand of the operator.

The shaping member 0, or beader, as it may appropriately be called, is adapted for cooperation upon the tapered surface portion 20 of the trowel B, and preferably includes the cylindrical shaped body portion 25, providing a tapered opening 26 which extends longitudinally therethrough, for the wedge shaped reception of the straight line and tapered surfaced portion 20, substantially as is illustrated in Figure 3 of the drawing.

Radial portions

28, 29 and 30 preferably extend from the cylindrical body portion 25, and are arranged entirely longitudinally of the header member These radial extensions are provided with different surfaces for effecting different beads or shaped depressions in the joints of plastic material. Thus, it is preferred to provide the convex arcuate surface 32 upon the extension 28; concave surface 33 of relatively short radius extending longitudinally of the extension 29; and convex surface 24: of relatively larger radius than the surface 33, provided upon the radial extension 30.

Referring to the use of the improved tool A, it is to be noted that the blade 10 thereof may be used in the ordinary and well known manner for spreading, shaping, or smoothing of plastic materials. The tapered hooked end portion 20 may be utilized independent of the shaping member 13, as

for tucking, that is, the fine marking of plastic materials, such as plaster walls, to provide artificial blocks or bricks, or the laying out of similar arrangements. In this connection,'the point- 21 is used. In pointing up or shaping of the joints or layers of plastic material intermediate blocks or bricks, the member C will find an effective use to quickly facilitate an operation. As illustrated in Figure 4:, the beader C when used upon the trowel B for providing concaved exterior surfaces in plastic joints, is so arranged that the convex surface 82 of the lateral extension 28 may be moved along the plastic material 40 intermediate blocks or bricks 41. In this position, the joint shaping member C is, of course, rigidly afiixed upon the tapered straight axis end ortion 20 against accidental rotation incident to the wedge action thereon. Similarly, beads may be provided in a plastic joint by utilization of the

concaved shaping surfaces

33 and 34, which may be selectively used merely by adjustment of the beading member C upon the supporting portion 20 of the tool A.

i From the foregoing description of this invention, it can. readily be understood that the improved tool is capable of selective use in connection with pointing, beading, jointer, or tucking. It is to be noted that beader C and the portion 17, are disposed upwardly of the hand engaging portion 16, and not below, thus facilitating the use of the trowel member B, and in no wise interfering with the effective grasp of the same by an operator.

Various changes in the shape, size and arrangement. of parts may be made to the form of invention herein shown and described, without departing from the spirit of this invention or the scope of the claims.

I claim:

1. As an article of manufacture, a shaping tool comprising a. substantially cylindrical shaped body portion, and radial projections extending therefrom and, longitudinally thereof provided upon their extremities with beading and shaping surfaces of various kinds.

2. As an article of manufacture, a tool for shaping of plastic materials comprising a cylindrical body portion provided with a tapered opening extending axially therethrough, and radial extensions on said body portion arranged longitudinally thereof provided upon their outer longitudinal surfaces with concaved and convex surfaces of various shapes and formations.

3. As an article of manufacture, a tool comprising a handle portion including a relatively straight upper end having a surface tapered to a point, and a member including various surfaces for the shaping of plasticmaterial having a tapered bore therein for detachable and adjustable reception of said tapered handle end.
