CONCRETE SCREED LEGS Filed May l1, 1948 Z0 rf' l @N IMEMOR. e] PAUL /4/. Cox SQ.

BY d( Patented May 8, 19515 UNITED STKTS ATENT erica 1 Claim.

Ihe screed is supported from screedA ported from the lower slab form upon screed' chairs or screed legs. These chairs or legs are usually ordered and made to a specic height to conform to the type of screed bar and the desired thickness of the concrete slab, thus necessitating different screed legs for different conditions. Often the slab form is not perfectly level and it is necessary to shim or out the fixed screed legs in order to level the screed bars.

This invention relates to a screed chair or leg for supporting the screed bars in reinforced concrete oor slab construction, and has for its principal object the provision of a simple, inexpensive device which can be quickly and easily adjusted to vary the height of the screed bars, and to level the same to accommodate any given construction conditions.

Another object of the invention is to so construct the device that it can be quickly and easily attached to the slab form without the use of nails or other attachment devices.

A further object is to so construct the device that it may be removed from the finished slab immediately after being struck on" to the desired surface level so that it may be re-used repeatedly.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and eiiiciency. These will become more apparent from the iollowing description.

In the following` detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.

In the drawing:

Fig. l is a cross-section through a concrete slab on a slab form, illustrating the invention in use supporting a flush screed bar;

Fig. 2 is a similar view, illustrating the invention in use supporting a screed bar above the surface of the slab;

Fig. 3 is an end view of the improved screed lee;

Fig. 4 is a side view thereof;

lll

Fig. 5 is a vertical section, taken on the line 5 5, Fig. 4; and

Fig. 6 is a horizontal cross-section, taken on the line 6 5, Fig. 4.

In Figs. l and 2, the concrete reinforcing bars usually employed in iloor slab construction have been eliminated for the purpose of clarity. In these figures the concrete floor slab is indicated at I B, with its supporting form at II.

The invention is designed more particularly for use with a wooden screed bar, suchV as a 2" x 2" or a 2 x 4, such as indicated at I2. It is not limited, however, to a wooden screed bar, as it can be used to support a pipe, metallic rod or bar.

The improved screed leg consists of a vertical post I3 terminating at its bottom in a pointed, threaded extremity Ill, the threads conforming to the usual wood screw design. A base plate or washer I5 is welded or otherwise secured to the lower extremity of the post I3 above the threaded extremity I4. U A plurality of spaced, relatively shallow notches i5 are formed in vertical alignment along one side of the post I3. A tubular sleeve portion II is rotatably mounted on the post I3.

A U-shaped plate saddle I8 is welded or otherwise secured to the upper extremity of the tubular sleeve portion Il to form a socket for the reception of the screed bar I2. The sides of the saddle i8 are perforated, as shown at I9, to provide nail holes, by means of which it may be xedly attached to the screed bar I2.

A small nail 2t* or a piece of wire is passed through nail openings 2l formed in the tubular portion II adjacent one side thereof so that the nail will pass tangentially across the post I3 and lie in one of the notches I6. The projecting extremity of the nail is bent downwardly along the sleeve I'I.

In use, the threaded extremity i4 is screwed into the form I I, as shown in Figs. 1 and 2. The tubular portion Il is adjusted vertically to bring the upper surface of the screed bar I2 to the proper level, as shown in either Fig. 1 or 2. The nail 2li is then passed through the nearest notch I6 in the post I3, and bent downward. The screed bars are then supported accurately in place ready for use.

Immediately after the slab has been poured and the top struck off level, the screed I2 is removed and the screed legs are rotated to the left so as to unscrew the screw I4 from the form II. The entire leg is then pulled upwardly to remove it from the concrete while still soft. The resulting s) hole is immediately filled with concrete and struck off to the surface level. Thus, the legs are not lost in the concrete and are ready for use on future `iobs While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claim, without departing from the spirit of the invention,

Having thus described the invention what is claimed and desired secured by Letters Patent is:

A screed support comprising: a vertical post; means on said post for supporting same in an upright position; a tubular sleeve slidably fitted over said post; a U -shaped screed saddle mounted on the upper extremity of said. tubular sleeve; a plurality of spaced-apart, relatively shallow, horizontal notches formed in vertical alignment along' one side of said post, there being a nail hole in said REFERENCES CITED The following references are of record in the iile of this patent:
