This invention relates to the field of masonry. More particularly, this invention relates to hawk boards that are used to deliver mortar to brick joints, such as when repointing the joints.
Brick and mortar is a commonly-used façade for buildings and other structures because of its resistance to weather and other damaging conditions. However, it is not unusual that, with time, the mortar in the joints between the bricks begins to age and crumble.
One remedy to this condition is to tear down the brick and mortar façade or structure and rebuild it. However, it is often structurally acceptable and much more cost effective to simply remove the mortar in the joints to a given depth and replace it with fresh mortar. This process is known as repointing.
After the old mortar in a joint is removed, the new mortar is brought in proximity to the joint on a board called a hawk, and a desired amount of the mortar is pushed into the joint with a repointing tool. The hawk is typically a flat board of wood, metal, or some other relatively resilient material, on which an amount of mortar is disposed. The artisan uses the mortar to fill the joints until the supply on the hawk is exhausted, at which time the hawk is replenished with a fresh supply of mortar.
Unfortunately, the prior art designs of the hawk have a few drawbacks that tend to result in a waste of mortar, money, time, and patience. For example, while it is easy enough to scrape a desired amount of mortar off of the planar surface of the hawk into a horizontal joint, it is much less easy to apply mortar to a vertical joint. The planar surface of the hawk isn't easily disposed in a vertical orientation to accommodate the vertical joint without the mortar sliding off the hawk, and if the hawk is kept in a horizontal orientation, then it is challenging to scrap more than just the tiniest amount of mortar into the vertical joint with each motion of the repointing tool.
Similarly, trying to apply mortar to outside and inside corners of the masonry is very challenging. It is difficult to position the hawk into an inside corner, and a hawk placed against one plane of an outside corner tends to drop mortar when repointing near the edge of the outside corner.
What is needed, therefore, is a hawk or a set of hawks that tend to reduce issues such as those introduced above, at least in part.
The above and other needs are met by a hawk having a first board with an upper surface, an opposing lower surface, and an edge. A handle is attached to the lower surface of the first board, and a hinge is attached to the edge of the first board. A second board with an upper surface is also attached to the hinge. An angle between the first board and the second board can be set as desired by selectively rotating the hinge between the first board and the second board.
In various embodiments according to this aspect of the disclosure, at least one of the first board and the second board includes a substantially ninety-degree cutout. In some embodiments, the first board and the second board have adjacent edges that form a substantially ninety-degree cutout between them at the hinge. In some embodiments, the first board and the second board have adjacent edges that form a substantially ninety-degree angle between them at the hinge. In some embodiments, the first board and the second board have adjacent edges that form a substantially sixty-degree angle between them at the hinge.
In some embodiments, the first board and the second board have first adjacent edges that form a substantially ninety-degree angle between them at the hinge, and opposing second adjacent edges that form a substantially sixty-degree angle between them at the hinge. In some embodiments, the handle includes a bore for receiving a pole. In some embodiments, the upper surfaces of the first and second boards include a texture. In some embodiments, the first and second boards are formed of at least one of wood, metal, plastic, and ceramic.
Further advantages of the invention are apparent by reference to the detailed description when considered in conjunction with the figures, which are not to scale so as to more clearly show the details, wherein like reference numbers indicate like elements throughout the several views, and wherein:
With reference now to
The hawk 100 can, in some embodiments, lie in the flat, planar position by merely holding the handle 104, where either the hinge 102 itself is configured so as to not allow the boards to rotate past a planar position with respect to one another, or stops are placed on the bottom of at least one of the boards so that the boards do not rotate past a planar position with respect to one another. Other structures for keeping the boards at either a planar disposition or at a desired default angle other than 180 degrees with respect to one another are also contemplated.
The boards can be placed into one or more or an infinite variety of angular positions with respect to one another in a variety of different ways, or using a variety of different structures. For example, in one embodiment the artisan can hold the handle 104 that is attached to one of the boards against the palm of his hand with his fingers, and use his thumb to incline the other board to any angle that he might desire. In another embodiment, a ratcheting structure is disposed on the hawk 100, such as underneath the boards or at one end of the boards, where the ratcheting structure can be set to hold the boards in a desired angular position.
In yet another embodiment, the hinge 102 has built within it locking positions, such as detents, that can be set to a desired one of a variety of different angular positions. Still further, a tensioning device, such as a threaded rod with a thumbscrew, runs through the hinge, and after the hinge 104 is placed into the desired angular position of the two boards, the thumbscrew is tightened, thereby retaining the hinge in the desired angular position.
With the hawk 100 disposed in the angular position as depicted in
With reference now to
By using a hinged hawk 100 with an angle between the two boards (such as at ends 114 and 116), the artisan is able to more easily deliver mortar to the joints that are disposed within an inside corner of the masonry, as the hawk 100 can be inclined toward the masonry, while keeping the effective angle between the boards as desired.

Various materials are contemplated for the construction of the hawk 100, such as woods, metals, plastics, ceramics, and combinations of such. The hawk 100 can have a variety of different sizes and shapes in different embodiments, such as eight inches square, ten inches square, rectangular, trapezoidal, irregular, and so forth.
In some embodiments, a selection of one or more of the hawks 100 as described herein is provided as a kit, which in some embodiments also includes one or more repointing tools.
As used herein, the phrase “at least one of A, B, and C” means all possible combinations of none or multiple instances of each of A, B, and C, but at least one A, or one B, or one C. For example, and without limitation: Ax1, Ax2+Bx1, Cx2, Ax1+Bx1+Cx1, Ax1+Bx12+Cx113. It does not mean Ax0+Bx0+Cx0.
The foregoing description of embodiments for this invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings. The embodiments are chosen and described in an effort to provide illustrations of the principles of the invention and its practical application, and to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally, and equitably entitled.
This application claims rights and priority on prior pending U.S. provisional patent application Ser. No. 63/115,109 filed 2020 Nov. 18, the entirety of the disclosure of which is incorporated herein by reference.
