The difficulties a mason encounters in building a straight wall are well known. Various devices have been developed which aid in that task. A mason is constantly challenged with brick alignment and in developing same with ease and rapidity. Guiding strings or lines are an accepted and well-established tool in alignment. Holding a guide line tightly is an inherent problem in alignment pursuits, as is ease of use of any tools involved in attempting to do so. The present brick laying alignment apparatus provides unique solutions to these problems encountered in masonry.
The present invention relates to masonry and more specifically to a brick laying alignment apparatus.
Prior art teaches several devices for assisting a mason in aligning bricks. Each has its own merits. Each differs from the present apparatus in design and function. Of additional importance is that the prior art devices are not reversible with regard to top and bottom, as is the present apparatus. The present apparatus also provides for component replacement, which is not taught in the prior art.
U.S. Pat. No. 3,119,186 issued to Stewart on Jan. 28, 1964 teaches a mason's line anchoring device. The device differs from the present brick laying alignment apparatus with regard to diversity, ease of use, and replaceable parts.
U.S. Pat. No. 2,948,065 issued to Simonic on Aug. 9, 1960 teaches a mason's line holding device which assists a mason in building a straight wall. The device, however, is not similar in design and does not offer ease of use and universality of the present brick laying alignment apparatus.
U.S. Pat. No. 3,461,565 issued to Harris on Aug. 19, 1969 teaches a mason's line stretcher whose operation is similar to the present brick laying alignment apparatus. The device, like that of Simonic and others though, lacks the refinements, parts interchangeability, and advantages of the present brick laying alignment apparatus.
While the above-described devices fulfill their respective and particular objects and requirements, they do not describe a brick laying alignment apparatus that provides for the advantages of the present brick laying alignment apparatus. In this respect, the present brick laying alignment apparatus substantially departs from the conventional concepts and designs of the prior art. Therefore, a need exists for an improved brick laying alignment apparatus.
The general purpose of the brick laying alignment apparatus, described subsequently in greater detail, is to provide a brick laying alignment apparatus which has many novel features that result in an improved brick laying alignment apparatus which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof.
To attain this, the brick laying alignment apparatus comprises two separate identical holders. Each holder is placed on a brick to serve as a guide for a mason. The holders are typically placed atop two remotely separated bricks that use a guide between for proper brick alignment of additional bricks to be laid. A string between the two separated holders thereby guides further brick laying. Each holder is placed with a top or bottom of the holder optionally facing upwardly. Each holder features a vee on the first end and a removable guide pin proximal to the second end. The removable guide pin is locked in place with a set screw. The vee of each holder is further comprised of a taper which joins each side of the vee with the outer side of the holder. Each side of the vee is termed a ramp. The tapers and the ramps of the vee provide for smooth guided engagement of the string with the wedge. The string is commonly used in brick alignment. The base or bottom of the vee extends into the wedge. The wedge extends briefly into the length of the holder, medially from the vee. The wedge provides frictional engagement of the string, thereby holding the string to the holder as needed. Each holder is further comprised of removable stagger bolts. The first stagger bolt extends perpendicularly upward from the holder and is most proximal to the vee. The second stagger bolt is more medially disposed and extends perpendicularly downward from the holder. The stagger bolts each, selectively and in conjunction with the guide pin, provide the means for engaging a brick. The holders are placed on remotely separated bricks. The string is anchored within the wedge of one holder and is also circled about the stagger bolt to be proximal to the brick. The string is then stretched to the opposing holder and temporarily anchored in the same fashion to that second holder. Pulling the sting tightly wedges the holders into contact with the bricks and provides a taught line for further brick laying alignment.
The apparatus is offered in a variety of material make-ups, including known metals, alloys, polymers, and plastics. The replacement capabilities of the guide pins and stagger bolts extend the useful life of the apparatus. Varied lengths of all components are provided as needed.
Thus has been broadly outlined the more important features of the improved brick laying alignment apparatus so that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.
It is therefore an object of the brick laying alignment apparatus to provide a guide for brick laying.
Another object of the brick laying alignment apparatus is to provide temporary attachment of the apparatus to bricks.
It is also an object of the brick laying alignment apparatus to provide quick attachment to and removal from bricks.
And, it is an object of the brick laying alignment apparatus to provide brick attachment with string tension only.
A further object of the brick laying alignment apparatus is to fit a variety of brick sizes.
An added object of the brick laying alignment apparatus is to provide separately replaceable components.
And, it is an object of the brick laying alignment apparatus to be of basic design.
Still another object of the brick laying alignment apparatus is inexpensive manufacture and sale.
These together with additional objects, features and advantages of the improved brick laying alignment apparatus will be readily apparent to those of ordinary skill in the art upon reading the following detailed description of presently preferred, but nonetheless illustrative, embodiments of the improved brick laying alignment apparatus when taken in conjunction with the accompanying drawings.
In this respect, before explaining the current embodiments of the improved brick laying alignment apparatus in detail, it is to be understood that the brick laying alignment apparatus is not limited in its application to the details of construction and arrangements of the components set forth in the following description or illustration. Those skilled in the art will appreciate that the concept of this disclosure may be readily utilized as a basis for the design of other structures, methods, and systems for carrying out the several purposes of the improved brick laying alignment apparatus. It is therefore important that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the brick laying alignment apparatus. It is also to be understood that the phraseology and terminology employed herein are for purposes of description and should not be regarded as limiting.
With reference now to the drawings, and in particular
Referring to
The guide pin 26 passes through the thickness of the holder 12. The guide pin 26 is proximal to the second end of the holder 12. The guide pin 26 fits within the pin orifice 30 of the holder. The guide pin 26 is perpendicular to the length and width of the holder 12. The guide pin 26 extends out of the bottom and top of the holder 12. The guide pin 26 is held in the desired position by the set screw 33. The set screw 33 fits within the set screw opening 32 disposed in the side of the holder 12. The set screw 33 is therefore perpendicular to the length of the holder 12. The set screw 33 is a hex screw. The set screw 33 retention of the guide pin 26 provides for guide pin 26 adjustment. The guide pin 26 is selectively positioned with reference to protrusion of the guide pin 26 from the top and bottom of the holder 12. The stagger bolt A 20 is disposed proximal to the wedge 18. The stagger bolt A 20 is parallel to the guide pin 26. The bolt 20 extends upwardly from the top of the holder 12. The bolt 20 is preferably comprised of a hex wrench head 22. The hex wrench head 22 provides the externally rounded head 22 of the bolt 20. Were the bolt 20 of a typical outer hexagonal head surface, eventual scarring and rounding of the bolt 20 would render the bolt 20 unworkable with a typical end wrench. Replacement of bolt 20 and stagger bolt B 21 is a valuable feature due to the fact that most bricks 50 (

Referring to each separate remotely disposed brick 50, a holder 12 is positioned with the holder 12 top facing upward and with the guide pin 26 removably fitted within the brick hollow 52. Each remotely spaced holder 12 is drawn toward the other via string 40 tension. The string 40 is secured to one of the holders 12. Securing the string 40 is most easily done by wrapping a segment of the string 40 around bolt 20, then passing the string 40 through the wedge 18 to secure the string 40 against slippage. The string 40 is then wrapped around the bolt 21. The string 40 is extended to the remote second holder 12. The string 40 is pulled taught and wrapped around the bolt 21 of the remotely positioned second holder 12. The string 40 is then passed through the wedge 18 and removably secured around the bolt 20. Pulling the string taught temporarily secures the opposed holders 12 in position in an interference bind with each brick 50, respectively. The string 40 thereby forms an alignment tool for the mason to align all bricks 50 between those engaged by the holders 12. Loosening the string 40 from either holder 12 allows removal of the apparatus 10.
Additionally, either or both holders 12 of the apparatus 10 may be inverted with respect to top and bottom of the holders 12. When the holders 12 are inverted, the bolt 20 is against the vertical member 53 of the brick. The bolts 20 and 21 are therefore used inversely regarding the above procedure with the string 40. The top or bottom of either holder 12 can face a brick 50. As the distance from the guide pin 26 to each stagger bolt 20 and 21 differs, turning the top or the bottom side of the holder 12 upward offers removable fitment to bricks 50 of different widths.
Turning the top of a holder 12 upward provides the shortest distance spread between brick 50 engaging components which are the guide pin 26 and the bolt 21. Turning the bottom of the holder 12 upward offers the longest distance spread between brick engaging components of the apparatus 10, namely the bolt 20 and the guide pin 26. The distance between the bolt 20 and the guide pin 26 is greater than the distance between the bolt 21 and the guide pin 26. The greater distance provides for fitting wider brick vertical members 53 and wider bricks (not shown) with the apparatus 10.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the brick laying alignment apparatus, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the brick laying alignment apparatus.
Directional terms such as “front”, “back”, “in”, “out”, “downward”, “upper”, “lower”, and the like may have been used in the description. These terms are applicable to the embodiments shown and described in conjunction with the drawings. These terms are merely used for the purpose of description in connection with the drawings and do not necessarily apply to the position in which the brick laying alignment apparatus may be used.
Therefore, the foregoing is considered as illustrative only of the principles of the brick laying alignment apparatus. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the brick laying alignment apparatus to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the brick laying alignment apparatus.
