The present invention relates to an adjustable gable line puller device for brick masons. More specifically, the invention relates to a gable line puller that may be adjusted to clamp to any size roof overhang, holding a leveling line while a bricked-in gable is being built.
The majority if not all houses require the construction of a bricked-in-gable under the roof. In constructing such gables, it is common practice to use a guide line suspended above the bricks that are being mortared into place under the gable. By following the guide line, the brick mason is assured that the stacked bricks and mortar remain even and level as the stack is built up even with the guide line suspended under the gable. Over the years, many devices have been utilized to suspend this guide line. Such a device is commonly referred to as a mason's guide line holder. In a classic arrangement for such a device, a pair of clamps suitable for holding a suspended line are attached to opposite ends of the gable face boards under the roof.
Over the years, various improvements have been made to the classic arrangement with respect to having to un-fasten and move, and re-set and re-fasten the pair of clamps as the stack of bricks becomes taller.
For example, U.S. Pat. No. 3,571,931 (Williams) uses a pair of clamps suitable for holding a mason's guide line and can be affixed to the gable face boards on the opposite sides of the roof. The problem is that the clamps must be adjusted and moved over and over and they are attached at the gable face boards farthest apart. Constructing a bricked-in-gable under a large roof overhang becomes quite time consuming and labor intensive because of the all the un-fastening, re-fastening, and adjustment of the clamps and guide line.
Obviously, having to move the clamps and re-adjust and re-fasten them takes time and creates an inefficiency in the task of building a bricked-in-gable. U.S. Pat. No. 5,964,042 (Carper) shows a device for holding a mason's guide line that utilizes a pair of clamps and a pair of angle irons. The angle irons are attached to the underside of the gable and the clamps are slid up and down the angle irons and provide an alternative clamping surface and trackway. Unlike the present invention, when the gable overhang is greater than 4.5 inches, this device requires that angle irons be affixed to the underside of the gable by screwing or nailing the angle irons under the gable, thus adding additional labor to the task of building a bricked-in-gable. Also, additional expense is added to the manufacture and ultimate purchase price of the device because additional metal and fabrication must take place to produce the appropriate angle irons to be used with the clamps.
Accordingly, the present invention describes an adjustable gable end line puller that solves all of the above problems.
The present invention broadly contemplates an adjustable gable end line puller comprising a pair of gable clamps, each clamp including: two horizontal members capable of telescopically extending and contracting from each other to accommodate roof overhangs; a fastener for attaching said gable clamp to a fascia board underneath the gable end of a roof, a fastener for holding a mason's guide line to said clamp; and a gap setting member for maintaining the appropriate width for the brick and mortar, said gap setting member pivotally and slidably mounted to the clamp; and a mason's guide line.
The present invention also contemplates a method for building a bricked-in-gable, comprising the steps of: attaching a clamp including: two horizontal members capable of telescopically extending and contracting from each other to accommodate roof overhangs; a fastener for attaching said gable clamp to a fascia board underneath the gable end of a roof, a fastener for holding a mason's guide line to said clamp; and a gap setting member for maintaining the appropriate width for the brick and mortar, said gap setting member pivotally and slidably mounted to the clamp; and a mason's guide line to the right most fascia board underneath the gable end of the roof, attaching an identically constructed clamp to the left most fascia board underneath the gable end of the roof, telescopically extending or contracting said horizontal members to accommodate the roof overhand; extending or contracting said gap setting member to the appropriate extension and angle for the width of the brick and mortar; attaching one end of a mason's guide line to the clamp attached to left most fascia board; attaching the other end of the mason's guide line to the clamp attached to the right most fascia board; and laying a row of bricks and mortar between the suspended mason's guide line and the stop fin of the gap setting member.
For a better understanding of the present invention, together with other and further features and advantages thereof, reference is made to the following description, taken in conjunction with the accompanying drawings, and the scope of the invention will be pointed out in the appended claims.
The present invention is an adjustable gable end line puller to aid in the construction of bricked-in-gables as depicted in
Now looking at
Horizontal member 14 is a rectangular piece of rigid material with an oval channel 18 and one adjacently fixed fin 27 at one end of horizontal member 14 and another adjacently fixed fin 26 parallel to fixed fin 27. Thumb screw 28 is rigidly fastened to moveable fin 25 but can still rotate clockwise or counter-clockwise. By turning thumb screw 28, the user moves moveable fin 25 through a horizontal plane to a suitable distance from fixed fin 26 allowing moveable fin 25 and fixed fin 26 to sandwich the fascia board tightly. It will be apparent that the combination of moveable fin 25, fix fin 26, fixed 27, and thumb screw 28 forms the fastener for attaching the gable clamp to a fascia board.
Horizontal member 13 and 14 have oval channels 18 and 17, respectively, and are attached to one another by placing bolt 15 through the oval channel 18 and oval channel 17 and washer 19 and wing nut 21. Similarly, bolt 16 is placed through oval channel 18 and oval channel 17 and washer 20 and wing nut 22.
It will be appreciated that loosening and tightening bolts 15 and 16 will allow horizontal members 13 and 14 to telescope in or out to accommodate various roof overhangs. In the present embodiment of the invention, these horizontal members are of dimensions sufficient to accommodate roof overhangs up to 16 inches, but larger clamps for larger overhangs could easily be fabricated following the teachings of the present invention.
Locking member 9 is pivotally attached to horizontal member 13 by means of bolt 7 and spring 10 having one of its ends pulled through bolt 7. Locking member 9 can be loosened to allow the mason's line to be pulled between it and the underside of sliding member 13. The mason's line is then pulled through the oval channel of the short leg of slidable member 13. The mason's line can be held in place by pivoting locking member 9 up against the underside of sliding member 13 and tightening bolt 7. Thus, the combination of bolt 7, locking member 9, spring 10, and sliding member 13 forms the fastener for holding the mason's guide line to the gable clamp.
It will be apparent to one schooled in the relevant art of brick laying that one need only adjust the width between moveable fin 25 and fixed fin 26 once for the entire project. Likewise, after adjusting horizontal members 13 and 14 to the proper distance for the roof overhang, there is no need to re-adjust. Finally, once the proper setting for brick and mortar width is selected on gap setting member 5, that adjustment is completed for the project.
Once the three adjustments are set on both a clamp mounted on the fascia board of the right side of the gable end of the roof and on a clamp mounted on the fascia board of the left side of the gable end of the roof, one need only pull the mason's line taught between the two clamps, securing each end of the line by pivoting each clamp's locking member 9 up to the underside of horizontal member 13 and tightening each clamp's bolt 7.
As the pile of bricks gets higher, the brick mason need only loosen thumb screw 28 on the right and left-mounted clamps, move the clamps up the fascia board and tighten thumb screw 28 on the right and left-mounted clamps. No other adjustments are necessary to operate this ingenious invention.
