Application April 10, 1957, Serial No. 652,000

10. Claims. (CI. 3385) This invention relates generally to a specialized tool for bricklayers and pertains more particularly to a tool assembly for providing a corner guide permitting the corner to be laid up entirely plumb and evenly and in a great deal less time than is ordinarily required.

In the art of bricklaying, it is well recognized that one of the most difficult tasks is to properly and quickly lay up a corner inasmuch as the bricks must be very carefully and evenly placed if the intersecting wall portions are to be disposed at the right angle to each other, usually in right angular relationship, and such that the arrises of the various corner bricks are in precise vertical alignment and are disposed in plumb relationship so as to effect a neat appearing and structurally efficient corner.

It is, therefore, a primary object of this invention to provide a guide assembly usable in association with an unfinished building structure to permit a brick veneer to be laid up on the outside thereof and to permit the corners to be accurately and precisely laid up, while at the same time the tool assembly is constructed in such a manner as to permit its being quickly and easily as sembled and without interfering with the laying up of the bricks.

It is another object of this invention to provide an improved guide assembly forbricklayers incorporating clamp means adapted to be associated with the corner wall structure over which a brick veneer is adapted to be laid and wherein a common piece of structurally light angle iron is utilized to effect a plumb line of constant reference for the bricklayer as the corner is laid up and wherein the guide utilizes bracket elements incorporated into the corner structure itself and later removable therefrom which effect fixed reference points so as to retain the angle or guide in proper relation to the corner and permitting its removal and replacement at will so that the same will not interfere with the construction of scaffolding and the like and which will, in all respects, most advantageously expedite the laying up of a corner.

With the above and other objects in view, the inven tion consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportions, and minor details ofsconstruction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Fig. 6 is a perspective view of one of the brackets, such as is shown in Fig. 5, but showing the same in upside down position; and

Fig. 7 is a perspective view of one of the wire retaining clips associated with the various brackets.

Referring at this time more particularly to Fig. l, the

. reference numeral 10 indicates generally the foundation portion of a building structure and the reference numerals 11 and 12 respectively indicate meeting right angularly disposed wall portions defining a corner of the building structure and illustrating the construction of the same before the brick veneer is laid up in facing relation thereto.

For accurately defining a fixed reference line for the vertical corner line of the veneer, a guide element'indicated generally by the reference character 13 is employed and in association therewith suitable support assemblies 14 and 15 serving to hold the same in place and with the inner vertical edge 16 of the guide element disposed in perfectly plumb relationship and opposed to the corner edge 17 of the walls 11 and 12 so that'the veneer may be laid up accurately and quickly and with a continuing and fixed reference line.

The guide means 13 is preferably constructed of a length of angle section having right angularly disposed leg portions 19 and 20 and with the guide means so associated with the building structure that the'outer face of the leg 19 is disposed parallel to the wall portion 11 and the outer surface of the leg 20"being disposed parallel with the outer surface of the wall 12. i

The upper portion of the guide means is supported by the assembly 15 which includes a clamp element 21 and an associated bracket 22, rigidly aflixed to each other and serving to rigidly support the corresponding upper end of the guide means 13.

Initially, the guide means is positioned and held in proper relationship not only by the upper clamp-assembly 15 but the lower assembly 14 which is similarly formed in the clamp portion 23 thereof but which utilizes a somewhat modified form of bracket assembly 24, as will hereinafter be more particularly disclosed. In any case, both of the bracket assemblies 21 and 23 are identically formed and each is constructed essentially of an elongate length of somewhat resilient rigid metal rod which is bent back upon iself to define a loop-25, such as is indicated in connection with the clamp assembly 21 and which loop is interconnected by the cross piece member 26 serving as a mounting means upon which the bracket 22 is attached and which includes the diverging leg portions 27 and 28, see particularly Fig. 2, which terminate in inwardly converging base portions 29 and 30 rigidly afiixed to the clamp plates 31 and 32 respectively and which may be suitably stayed or braced thereon as, for example, by the members 33 and 34. The clamp plates are provided, preferably, on their inner faces with hobs 35 or similar projections to place into and frictionally hold in the wooden wall portions 11 and 12. Adjacent the juncture of the leg 28 and the base portion 30, there is secured in depending relation thereto, a suitable nut 36 as is shown most clearly in Figs. land 2 and adjacent the juncture between the leg 27 and the base portion 29- and in depending relation thereto, is a tab element. The tab element is provided with an' apexture to receive the T-bolt member 38 which has a threaded end portion 39 engaged with the nut 36 and which is provided with spaced locating collars 4t) and 41 disposed on opposite sides of the tab and serving to fix the bolt 38'against longitudinal movement relative to the leg 27. The head of the bolt 38 is provided with a cross piece 42 by means of which it can be easily and readily turned and it will be manifest that rotation of the bolt in a counterclockwise direction will feed the nut 36 toward the free end thereof and serve to move the two legs 27 and 28 apart and, consequently, move the associated clamp plates 31 and 32 out of clamping engagement with the wall corner.

Each of the assemblies 14 and it attached to its associated bracket members 22 or 24 in an identical manner. As is shown most clearly'in Fig. l, the bracket 22, for example, is supported on its associated assembly 15 through the medium of the cross bar 26 and the associated wing nuts 43 and 44. The wing nuts cooperate with bolt or stud members carried by the cross bar 26 so as to aflix the bracket 22 to the cross bar 26 and yet to permit a slight degree of adjustment of the bracket with respect to its supporting assembly 15. As shown in Fig. 3 the bracket has apertures to receive the bolt or stud members with suflicient looseness to permit the adjustment. These apertures may be circular holes as shown, as desired. This adjustment is necessary in order to permit the bracket 22 to adequately and properly position the angle guide member 13 with respect to the corner 17. The upper bracket 22 is attached to the guide element 13 in a manner which is different from the mode of attachment of the lower bracket 24 to the guide and the construction and attachment of the bracket to the guide member is shown more clearly in Fig. 3.

In this figure, it will be seen that the outer end of the guide bracket 22 is provided with a V-shaped notch which straddles the outer faces of the guide legs 19 and and which notch is defined by down turned flap portions 45 and 46 depending from the main body portion of the bracket 22 and which fit flush against the outer sides of the respective legs 19 and 20. These flaps 45 and 46 originally extend beyond the associated ends of the bracket and are turned back upon themselves to present the end tab portions 47 and 48, each of which is provided with an opening threadedly receiving a set screw element 49 or 50 by means of which the bracket can be rigidly clamped to the guide element 13. From Fig. 3, it will be apparent that the bracket 22 must be engaged over the end of the guide assembly 13 so as to straddle respective legs 19 and 20 and can then be slid along the length of the guide member and positioned properly in respect thereto, after which the set screws 49 and 50 are tightened to hold the desired adjustment and support the guide element from moving vertically.

The lower bracket has its guide element engaging end portion constructed in a manner similar to the bracket 51 illustrated in Fig. 6. The bracket 51 is provided with a V-shaped notch 52 and two end tab portions 53 and 54 as shown. The end tab portion 53 is provided with an inwardly extending shoulder portion 55 which engages over the end edge of a cooperating leg 19 or 24) of the guide element and the opposite end tab p rtion is provided with a rectangular recess 56 which receives and engages with the edge of the opposite- leg 19 or 20. The purpose of this construction is to permit the bracket 51 to be engaged in proper relation with the guide element with ut the necessity of engaging it over the end of the guide element and sliding it along the same. In other words, the bracket 51 may be placed at the exact position on the guide element 13 that is desired and the bracket 24 is identically constructed in its end portion so as to engage the guide element 13.

Each of the end tab portions 53 and 54 is provided with apertures 57 and 58 to receive a retaining clip element 59 as is indicated most clearly in Fig. 7. The

retaining clip 59 includes a cross piece 60 and a pair of depending leg elements 61 and 62, the latter of which project through the apertures 57 and 58 with the cross piece 60 bridging the space therebetween and serving to abut free longitudinal edge portions of the legs 19 and 20 and prevent accidental disengagement of the guide element from the associated bracket with which the clip is used.

The bracket 51 may most properly be termed an auxiliary bracket, for purposes which will be presently apparent and will be seen to include an inner end portion having a pair of spaced parallel feet 63 and 64 thereat which are joined integrally With the main or central body portion 65 of the bracket. Adjacent the juncture of these feet with the body portion 65 and midway therebetween is a V-shaped tongue 66 and on opposite sides thereof the downwardly struck tabs 67 and 68 which are disposed in right angular relationship to each other. In using the auxiliary bracket 51, the feet 63 and 64 are laid on top of a corner brick 69 with the depending tabs 67 and 68 abutting the corner faces of the brick in the manner shown most clearly in Fig. 5 and with the tongue 66 resting upon the upper face of the brick together with the feet 63 and 64. When the bracket is thus placed, after having been engaged with the guide element 13 retained in proper relation thereto by means of the clip 59, mortar 70 is placed on top of this and another course or two of brick laid on top of it so as to firmly affix the bracket 51 in place.

In using the device, the two clamp assemblies 14 and 15 are first secured in position and then their associated brackets 22 and 24 are adjustably attached thereto so that the guide element 13 is properly positioned with respect to the corner 17. The lowermost clamp element 14 and its associated bracket is placed a sufficient distance above the foundation to permit several courses of rick to be laid before the height of the clamp 14 is reached. This permits the use of an auxiliary bracket 51 at a position lower than the bracket 24 which, by the time the mason has reached the height of the clamp 14, will be sufficiently rigid with respect to the brick work due to the hardening of the corner, to permit the auxiliary bracket 51 to entirely replace the bracket 24, in which case the same, together with its clamp assembly 14, may be entirely removed with the auxiliary bracket 51 serving as the sole supporting means for the lower end portion of the guide assembly 13. A further auxiliary bracket may be placed somewhere below the uppermost guide supporting assembly 15 and associated bracket 22 so that when the height of the uppermost bracket assembly 15 is reached, the same may be removed and replaced higher up on the wall with the associated auxiliary bracket originally placed immediately therebelow serving as the lowermost support for the guide assembly.

It is to be appreciated that the vertical height of the guide element 15 is preferably chosen so that when the height of the uppermost bracket assembly 15 is reached, it will be time to build the scaffolding for further work and in this respect, it is to be noted that it is a simple matter to remove the guide assembly together with the removable clamp assemblies associated therewith, leaving only the rigidly attached auxiliary elements to serve as a reference point for later repositioning the guide element after the scaffolding has been built so that the guide assembly, at no time, will constitute an impediment to building the scaffolding. The auxiliary bracket members present no special problem after the brick work is completed inasmuch as they can be grasped by a pair of pliers or a similar instrument and forcibly removed from between the adjacent courses of brick where they were originally. placed and yet the mortar will normally hold them sufliciently rigid for proper operation of the guide element 13.

Fig. 4 illustrates a further advantage of the invention in that the guide or chalk lines and 76 can be easily and readily attached between any adjacent pairs of guide assemblies 13 by simply using the hook elements 77 and 78 as shown or equivalent elements to secure the ends of the lines and in this connection, it may be preferred to provide the outer faces of the legs 19 and 20 of the guide elements with bricklayers scales so that the attachment is rendered still more beneficial.
