United States Patent 3,113,383 MASONS JIFFY POLES Dale R. Dithrnart, 1141 15th Ave. 8., Clinton, Iowa Fiied Aug. 3, 1959, Ser. No. 831,221 1 Claim. (61. 33-85) My invention relates to an improved appliance for setting and holding the leveling cords or masons lines used by bricklayers, stone masons, and tile setters, to guide them in securing all the bricks and blocks of each successive course of 12L brick, stone, tile or concrete wall at a common level and for facilitating movement and replacement of such lines or cords at successive heights.

The objects of my invention are to provide a suitable vertical post in firm position adjacent either the inner or outer corners or at the side of a wall with a plurality of adjustable guide clamps fitted thereon, adapted to secure one or more masons lines thereon under sufficient tension to hold them level; to provide resilient means mounted upon such clamps to cause them to adhere in adjusted position upon such a post until moved manually; to provide a form of clamp and post assembly which will be strong, durable, and can be economically manufactured and sold at moderate prices, and with clamps that can be mounted and moved upon the pole easily and rapidly.

I accomplish these objects by the means illustrated in the accompanying drawings, in which:

FIGURE 1 is a side elevation of the anglebar pole with one of its lugs in dotted lines with part broken away to shorten the figure;

FIGURE 2 is an enlarged detail plan view of one form of slide;

FIGURE 3 is an enlarged plan of another form of slide with its pin holder at the angle of the anglebar;

FIGURE 4 is an enlarged detail of the base or foot plate showing the position of the anglebar and lugs there- FIGURE 5 is a side view of the foot plate or base and lugs thereon;

FIGURE 6 is a detail of the spring;

FIGURE 7 is a detail of the slide and spring mounted thereon at an inner corner of a building shown only in dotted lines;

FIGURE 8 is an enlarged perspective of a slide and the locking spring mounted on the slide and a hand in position to release the spring pressure upon the flanges of the anglebar as outlined in broken lines.

Similar numerals refer to similar parts throughout the several views, and the size, shape, weights and materials may be varied as varying existing conditions may require.

My post 11 is preferably of iron, steel or aluminum about 8 feet in height and is welded or otherwise secured to a base plate 1 and may be additionally secured by lugs 3 united to the base, and by a brace board not shown.

I prefer for posts anglebars with flat flanges united at their inner edges to form a square corner and standing at an angle of 90. The flanges should preferably be about A of an inch thick and from 1 to 2 inches wide.

Slides or clamps 4 are formed by strips of sheet metal preferably about 1% inches wide and long enough and bent to surround the anglebar closely with the ends dA-SB of the strip coming together at the open side of the anglebar and overlapping. The ends are secured together by a screw 6 which passes through openings in the ends secured by a wing nut 7 or other suitable means. The openings for the screw 6 in one or both overlapping ends of the slide or clamp is made a little longer or larger than the body of the screw '6 whereby a limited amount of play is allowed when the screw is loosened to allow adjustment or is tightened to secure the slide rigidly on the pole 11.

The clamp-slide is thus triangular in form. It has tubes one of which 4-" stands at the corner of the post when at the outer corner of a building as in FIGURE 1, and one of which 9 is secured at the outer edge of one of the flanges of the post when at an inner corner as in FIG- URE 7.

These tubes are made in size corresponding to the diameter of a nail, preferably a 10 or 12 penny nail, or a pin to be mounted therein with its head or point protruding to allow a builders cord 12 or masons line to be tied thereon and should be strong enough to stand the line tension required for each particular wall.

The clamps are made of sheet metal preferably of galvanized iron, stainless steel, brass, or aluminum, but may be of any suitable alloy.

The triangular clamps or slides are made just large enough to slide along the post when manually lifted or pushed and when not held by the resilient locking means to be described.

To lock a clamp in position, a unitary strong spring wire -13 preferably of about No. 9 gauge, is bent as shown in FIGURES 6, 7 and 8 to follow the upper and lower edges of the clamp slides partly around the clamp. This wire is mounted in tubular sockets 4 and 8' integral with the clamp strip 4 or 8 and has outwardly projecting curves or angles 13B and 13A at the contact of its upper and lower lines with the edges of the flanges of the post 11.

These curves in normal position exert pressure inwardly against the edges of the post flanges suificiently to maintain the clamps in their adjusted positions but by manual pressure applied to the portions of the spring midway between the free edges of the flanges and tending to force them toward each other, may be moved outwardly sufficiently to release their pressure upon the post and permit the operator to slide the clamp along the post and thereby set it in a new place to arrange his lines at the proper level to add another course or row of bricks, stone or other building material.

At the top of each post a similar clamp is positioned with strips of sheet metal or its equivalent mounted on the upper and lower ends of the nail or pin carried thereby. These strips are nailed or otherwise fastened to the sheeting or timbers of the building for which the brick, stone, etc. is being laid.

The lower end of each post is rigidly secured by welding or other suitable means to a metal foot or base plate 1 of iron or other suitable metal, which may rest upon the bed upon which the foundation of the building is laid or upon the foundation itself or upon any suitable supporting means to be provided therefor at the various heights to which it must be carried for various structures.

It may project a half inch more or less into the plaster course below a course of bricks. It will be of suflicient size to afford a firm mounting for the post, preferably about 5 or 6 inches in length and width.

In addition to the foot plate 1 described, the post will also be firmly held in place at or near the top of the post by the means described above.

Various modifications may be made in the kind of metal, size, and shape of the various parts without departing from the spirit of my invention as set out in the claim and I do not limit my claim to the precise forms shown in the drawings.

I claim:

An adjustable appliance to secure a masons line in fixed position upon a vertical metal anglebar comprising a triangular rustproof sheet metal slide about one inch in width surrounding the anglebar with overlapping ends adjustably secured in the space between the free edges of the flanges of the anglebar, and a vertical tubular holder integral with the slide at one of the angles thereof with a strong nail seated therein with a projecting end on which a masons cord may be secured and held stationary under proper tension, and a strong wire spring having parallel integral upper and lower members partially surrounding the anglebar with their ends mounted in tubular sockets added to and integral with the slide and pressing against it to secure the slide in adjusted position, parts of said spring being manually movable to relieve the pressure of the spring upon the slide.
