1939, Serial No. 260542 (Granted under the act of March 3, 1883, as

amended April 30,

The inventicn described heroin may be manufactured and used by or for the Government of the United States for governmental purposes without the paynent to me of any royalty thereon in accordance with the provisio ns of the act of Aprl 30, 1928 (Ch. 460, 45 Stat. L. 467).

This invention relates to waterproofing masonry walls, but more particularly the brick walls of buildings, and the invention has for its object to provide simple, cheap and durable "stenciling hawks", by means of which the waterproofing rout may be quickly applied to the mortar joints of a brick wall in a highly efficient, effective and economical manner, so that upon completion of the waterprocfing operation, the wall is left with an improved smooth and finished appearance and without the necessity of any cleaning or removal of excess grouting material therefrom.

With this object in View, the invention consists of the novel construction and arrangement of the stenciling hawks, which for convenience of operation and most satisfactory results, should be used in pairs in the manner of and for the purposes hereinafter described.

Referring to the accompanying drawings:

Fig. 1 is a plan View of one of the pair of stenciling hawks used in the operation of waterprooing the horizontal joints between the courses of a brick wall.

Fig, 2 is a vertical sectional View through the same.

Fig. 3 is a plan View of the other one of the pair of stenciling hawks used in the operation of waterproofing the vertical joints between the bricks.

Fig. 4 is a Vertical sectional view through the same.

Fig. 5 is a plan View illustrating the application to brick wall of the stenciling hawk shown in Fig. 1, and

Fig. 6 is a similar View showing the application to a brick wall of the stenciling hawk shown in Fle. 3.

Like numerals of reference indicate the same parts throughout the several figures, in which:

l indicates the stenciling hawk shown in Fig. 1 which I will designate as the horizontal hawk and 2 indicates the stenciling hawk shown in Fig. 3, which I will designate as the vertical hawk.

On each of the stenciling hawks l and 2 there Extending upwardly from this trough 3, and preferably integral therewith is a fiat metallic back-member 4. suitable ends 5 are provided for the troughs 3, and I prefer to provide a suitable bead at each of the vertical edges of the hawks 5 for the purpose of stiffening the structures.

In the horizontal hawk l (Fig. l) there is pro- Vided a longitudlnal horizontal open slot 'l in the flat back-member 4 which slot extends through nearly the entire width of the back-member 4; that portion of the material at the ends of the slot l being provided with a rear-way extending bead or crimp 8.

Arrangecl on the front and rear sides of the back-member 4 and along the horizontal edges OI" the slot 'l are two fiexible rubber strips 9, the edge portions of which slightly overlap the top and bottom edges of the slot l, as shown in dotted lines in Fig. 1.

The vertical stenciling hawk 2 (Fig. 3) is provided in its back-member 4, with two horizontal rearwardly extending heads or crimps te and Il, spaced apart a distance equal to that of the mortar joints between two Courses of brick, while centrally of the back-member is an oblong opening I 2 which extends from the center line of the upper bead or crimp lil to the center line of the lower bead or crimp l i. Suitably Secured to the rear surface of the back-member 4 is a small fiexible rubber sheet !3 having a vertical slot M provided therein, the edge-portons of which sheet acljacent its slot !4 overlap the vertical edges l of the oblong opening z in the metallic back-member 4.

The widths of the horizontal opening between the two rubber strips in Fig. 1, and of the slot in the rubber sheet !3 in Fig. 3 is equal to the widths of the horizontal and vertical mortar joints between the bricks, while each of the stenciling hawks is provided centrally of their troughs 3 with a depending handle !5, for convenient support and correct positioning of the hawks by the hand of the artisan using them.

Having thus described the Construction of the stenciling hawks, the manner in which they are 45 used in the application of waterproofing grout to the joints of brick walls is as follows:

A quantity of suitable waterproofing grout is placed in the trough 3 of the stenciling hawk l, and the hawk is placed against the surface of 50 the wall ll, as shown in Fig. 5, so that the beads or crimps 3 therein register in the horizontal mortar joint !8 of the wall. This aligns the horizontal slot 'l of the hawk with the horizontal mortar joint so that the entire joint within the 55 length of the slot 7 is exposed, but the contiguous surfaces of the bricks are covered by the backmember of the hawk. When in this position, grout contained in the trough 3 is brushed into the mortar joint which is exposed through the slot l. By reason of the flexible rubber pieces 9 at the top and bottom edges of the slot 1, a close contact is preserved at the adjacent edges of the bricks sufiicient to prevent the grout from running down behind the back-member of the hawk and over the surface of the bricks. By this construction the surplus grout from the stiff brush s caused to run down the outer face of the backmember and into the grout trough 3, thus conserving the grout and obviating all waste. The hawk is moved along the horizontal joint as fast as the grout can be brushed in.

When using the vertical hawk 2, it is similarly placed against the wall surface so that the two horizontal beads or crimps o and II thereof register with two horizontal mortar joints !8, and the vertical slot M thereof uncovers a vertical mortar joint between two bricks. The grout is then similarly applied with a stiff brush and brushed into the joint. Similarly the flexible rubberin which the vertical slot !4 is formed provides a close contact With the adjacent faces of the bricks sufcient to prevent the grout from running down behind the hawk and over the surface of the bricks. Likewise the surplus grout from the stiff brush is caused to run down the outer face of the hawk and into the grout trough. The hawk is moved from joint to joint in order to complete the application of the grout to the vertical joints in the wall.

Having thus fully described the use of the stenciling hawks in the application of waterproofing grout to the horizontal and vertical mortar joints of a wall, I do not wish to be understood as confirming myself to the exact Construction of the hawks as illustrated in the drawings and described herein, since such illustration and description is only intended to disclose what I consider to be an example of a simple and satisfactory Construction. Various changes, alerations and modifications may be made in the Construction and arrangements of the parts without departing from the spirit of the invention, and I consider myself clearly entitled to all of such as fall within the limit and scope of the appended claims.
