pt- 1932- e. CORNUELLE BRIC KLAYER'S LEVELING AND PLUMBING DEVICE FiledMarch 29, 1929 2 Sheets-Sheet ATTORNEY.

Patented Sept. 20, 1932 V UNITED STATES BRICKLAYERS LEVELING AND PLUMBING DEVICE Application filed March 29, 1929. Serial no. 351,021 q My invention relates to devices with which bricklayers may insure the proper leveling and plumbing of courses of brick in brick construction work.

3 In brick construction work there is ordi narily a particularly skilled bricklayer who lays the corners, and during the progress ,of the work stays ahead of the other bricklayers sufficient to permit a line, usually secured by it nails set in the corners, to be run from corner to corner to indicate the proper position of the brickwork between the corners. The corner layers usually receive extra compensation for their work, which involves not only 15 the provision of the proper guidance for the laying of the bricks in proper horizontal alignment, but also the proper plumbing of the wall which the corner man determines by the use of a plumb line or spirit level. 23 It is the object of my invention to provide a corner guiding device, which when once properly aligned will serve as a substantially absolute guide for both the laying of the bricks in courses, and also for the proper S3 plumbing of the walls. The above broad object and other specific objects to which reference will be made in the ensuing disclosure,

I accomplish by that certain combination and arrangement of parts of which I have shown a preferred embodiment.

Referring to the drawings:

Figure 1 is a perspective viewof a wall during construction with my leveling and plumbing device in position.

Figure 2 is a detail horizontal sectional view of the device on an enlarged scale.

Figure 3 is a perspective view of one of the sliders which retain the line.

Figure 4 is a perspective view of the device viewed from the inner corner.

Figure 5 is a perspective view from the outer corner, with a slightly different type of support, than is shown in Figure 4:. indicated.

The device is composed of an upright guide formed from a strip of metal bent into a square shape with outer side walls 1 and 2, and With inner side Walls 8 and 4. The walls 3 and 4 are bent back so that flat surfaces 5 and 6 are provided at right angles, one to the other, with an opening 7 between them extending into the hollow formed by the square piece of metal. The fiat surfaces -5 and 6 may be used for crayon markings to indicate courses or they may be calibrated. Hooked ledges 9 and 10 are provided by bending back the edges of the pieces formingthe surfaces 5 and 6 as clearly indicated in the drawings.

PATENT oFFIcE Sliders composed of fiat pieces 11 are pro videdwhich have bent edges 12-which engage 11111118 hooked ledges 9 and'lO, and are slidable therein. The pieces haveslits 13 with the upper portions 1 1 bent back at a slight angle so as to provide means for securing the levelmg line in place, as clearly indicated in Figures 2 and 3. Tongues 15 are bent down from t'he pieces 11 to provide ledges which preferably bot-h retains the-slider within the hooked ledge and which provide gauges which will seat on top of a brick wall during its construction and give the proper horizontal align-Y ment to the line retained within the slits 13' parallel therewith.

.There will preferably be two sliders for 7 each upright support, onea right, and the other a left. The square corner pieces will; have aligned holes extending therethrough as indicated at'l6, so that brace rods 17 may be extended therethrough to retain the .de: vice in proper position.

For mounting the device a metal sup-port 18, as indicated in Figure 4, or an angle brace as indicated in Figure '5 at18a may be provided which is first set on the foundation on which the brick work is to be laid. The cornerangle iron may be secured in the corner'of the foundation by any other desired means however. The square upright support is first plumbed with a plum line or spirit level and as the brick work progresses the line extending between corners is substantially exactly onthe proper line for upper outer edges of the bricks. Thus, more exact brick laying may be done and the necessity of a master craftsman to lay the corners is avoided, as with my device, poor brick work can only be done by the utter disregard of the men working, to the leveling 1 device which I have provided. 7

Having thus described my invention, what I claim as new and desire'to secure by-Letters Patent, is

1. A bricklayers leveling and plumbing device comprising an upright support com posed of metal formed in the shape of a hollow square, opposed meeting portions of-said support at one corner being bent outwardly and then inwardly thus providing vertical guides, said guides-providing an opening v therebetween in the hollow square extending j vertically, said outwardly bent portions extending at right angles to one another on either side of the opening to provideangles for mounting the support on the outer corner of a brick wall during its construction, sliders verticallymovab-le insaid guides, said sliders having ledge portions for seating on thetop surface of a course of bricks, and slotted line.-

device comprising, an upright support composed of metalformed in the shape of a hollow square, opposed meeting portions of said,

support at one corner being bent outwardly 'and then inwardly thus providing vertical guides, said guides providing an opening therebetween in the hollow square extending vertically, said outwardly bent portions eX- tending at right angles to one another on either side of the opening to provide angles ,7 for mounting the support on the outer corner' of a brick wall during its construction, sliders vertically movable 'in said guides, saidsliders having ledge-portions for seating on the top surface of a course of bricks, and

said sliders having slotted portions for they reception of a chalk. line, the terminus of said slots being in horizontal alignment with a said ledge portions.
