MASONS HAWK.

SPECIFICATION forming part of Letters Patent No. 348,268, dated August 31, 1886.

Application filed October 23, 1885. Serial No. 180,695.

.T0 all whom zt may concern:

Be it known that 1, ROBERT R. CoUEsEN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Masons Hawks; and I do hereby declare the following to bea full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide a masons hawk of increased durability, one that will not absorb water when brought into contact with the plaster, and thus become unduly heavy, and one that, when not in use, will not warp and split when dry.

The invention consists in the arrangements and combinations of parts, substantially as will be hereinafter set l'orth and finally be embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like let-ters indicate corresponding parts in each of the figures, Figure lis a side elevation ofthe improved hawk. Fig. 2 isa vertical section of the same. Fig. 3 is a plan ofthe under side of said hawk, and Fig. 4 is a vertical section illustrating certain modifications of construction.

In said drawings, a is a handle, which provides a base or support for the board for holding the plaster. Said handle is preferably of wood. b is said plaster-holding board. This is of terra-cotta,such as is used commonly for building purposes, or it may be of other like earthen material. Said board is saturated with shellac or other water-resisting matter, which completely lls the pores of the board. Through the center of the board, as shown in Figs. 2 and 4, is or may be arranged a sheet of wire-cloth, c, which adds strength and cohe- (No model.)

sion to the board, preventing the same from fraeturing should it accidentally fall. wire-cloth may be inserted between two of the earthen boards, while they are inaplastic or semi-plastic state, the plates or boards being then subjected to pressure and iirml y united and then burned.

In Figs. 2 and 3 is shown an improved handle, the same being provided with a tlangemt, by which the handle is secured to the plasterboard by screws from the bottom, as shown.

Having thus described the invention, what I claim as new is l. The improved masons hawk combining` therein a terra-cotta or similar earthen board and a handle, substantially as and for the purposes set forth.

2. The improved masons hawk combining therein a terra-cotta board having its pores iilled with shellac or equivalent matter, and a suitable handle, as set forth.

3. The improved masons hawk combining therein the earthen board, wire-cloth, and handle, substantially as and for the purposes set forth.

4. A masons hawk having the Ybody or board thereof composed asa Whole or in part of terra-cotta or equivalent plastic material, substantially as set forth.

5. A masons hawk having a body or board of terra-cotta and wire-cloth, substantially as and for the purposes set forth.

6. A masons hawk having wire-cloth arranged between uppcr and lower sections of the board thereof, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 21st day of October, 1885.

ROBERT R. COURSEN.
