Specification of Letters Patent.

Serial No. 709,782.

To all whom, it may concern:

Be it known that I, JOHN T. SAL'rmL. a citizen of the United States of America, residing at Les Angcles, in the county of Los Angeles and State of California, have invented new and useful improve]nents in Concrete Building Construction. of which the following is a specification.

This invention relates to improvements in concrete building construction and has particular application to reinforced concrete structures. It is to be understood. however, that the invention in its useful application is not limited to concrete construction, as the same may be employed wherever reinforced plastic materials are utilized for building and other purposes.

In carrying out the present. invention, it is my purpose to provide means whereby the reinforcing means of the plastic mass may be held within such mass and away from the forms or false work, so that the reinforcing means may be embedded in the plastic mass in an even and uniform inanner so as to st rengthen the structure. l urthern'iore. I aim to provide means for holding or supportingthe reinforcing means for the plastic material away from the forms so that the plastic mass forming the structure may surround the reinforcing elements whereby such mass will possess relatively great strength after the same has I settled. the means preferably embra ing the constituent parts of the plastic mass and remaining therein after such mass has settled and become hardened.

\Vith the above and other objects in view, the invention consists in the construction, combination and arrangement of parts here inaftcr set forth in and fallingwithin the scope of the claim.

In the accom ianyingrdrawings there has been illustrated certain preferred and practical embodiments of my invention. and in these drawings. Figure 1 is a detail perspective view of a plurality of intersecting reinforcing bars equipped with the present invention. Fig. 2 is an enlarged herspcctivc view of a detail of Fig. 1. Fiji. 3 is a sectional view of a reinforced plasti mass illustrating: the application of the present invention, the plastic material being mounted upon the form. Fig. 4, is an enlara'ed transverse sectional view of one of the supports of the reinforcing bar hown in Fig. 1, the parts being broken away. Fig.

3 is a. top plan view of a modified form of the invention. Fig. 6 is a perspective view of a further modification of the. invention and Fig. 7 is a sectional view through the. support shown in Fig. (3.

In the building of reinforced concrete structures and the like, the reinforcements -are usually placed upon forms or false work commonly known as framing and the con crctc or other plastic material poured upon the form -and around the reinforcing means. llcretofore, it has been a common practice for the workmen employcd to utilize any thing handy for the purpose of spacing the reinforcing bars and the like from the forms. so that the plastic mass would iucase the reinforcements. This method of maintaining the reinforeements spaced from the .forms has many objectionable features among which may be enumerated, the lack of uniformity resulting from uneven positioning: of the reinforcements throughout the body of the plastic mass, incident to the utilization of wooden and iron plugs, strips and the like of various lengths to hold the reinforcements spaced from the framework, and the weakening of the hardened mass resulting from the uneven positions of the reinforcements. By means of my invention. these and other objectionable features heretofore inherent; in reinforced concrete building construction are eliminated. and the reinforcements spaced from the forms in an even and uniform manner so that the plastic mass or material may incase the forms. and when hardened, possess the strength commensurate with the bulk of the plastic mass and the reinforcing means therein. The supports for hold ing the reinforcing means spaced from the forms preferably embrace the constituent parts of the plastic mass and are embedded therein so that when the mass has settled or hardened, an integral structure will be presented and the reinforcements arranged therein in an' even and uniform manner to equalize and distribute the weight to all parts of the structure. t

Referring now to the accompanying drawings in detail. and particularly to Figs. 1 to 4 inclusive. A designates the form or false work commonly known to those skilled in the art as framing. and up n su h f'ams or false w rt; ar arrain' -d in map; means for holding the rci rccnicnf s i-i from the form. This bedding n eans in the present instance, embraces a plurality of blocks a. each having formed in one surface a hingitudinal relatively deep groove .1 and a shallow groove 2 arranged at right angles to the groove 1 and intersecting such groove approximately centrally of the block. This form of my invention is designed to be utilized in conjunction with reinforcing bars of any cross s ctional contour which bars, are. as usual arranged longitudinally and transversely ofthe plastic mass, the longitudinal bars being indicated at 3 While the transverse bars are denoted by the numeral 4. The longitudinal bars herein shown are arranged beneath the transverse bars and are disposed in the relatively deep groove 1. while the transverse bars lie within the shallow groove and above the bars 3. If desired, the various bars. at the points of intersection. may be tied to each other by means of wire or the like 5 to maintain the bar in proper position. After the holding blocks and bars have been positioned up n the framing. the. concrete or other plastic nmterial is poured upon the same and owing to the reinforcing bars being spaced from the frame. such bars will be incased in the mass and the blocks embedded therein.

The manner of assembling the blocks just described may be briefly stated as follows: Assuming the framing or form to be as seinbled. the blocks a are positioned thereupon and arranged at appropriate distances apart. The longitudinal reinforcing bars are then placed upon the blocks and in the alining relatively deep grooves thereof, suit se luent to which action the transverse bars t are placed in the alining shallow grooves of the respective blocks and upon the loogitudinal bars. The tie wires, if such are used, may then be wrapped about the respective bars at the points of intersection. 'lhe concrete (1 or other plastic material is now poured over the reinforcing bars and blocks and env lops the reinforcing bars, incident to the same being spaced from the form, and when the mass becomes'set or hardened. the blocks a will be embedded therein and form therewith an integral structure.

The form of block disclosed in the modification illustrated in Fig. 5 is designed for use with wire screening or the like for reiuforcing the plastic mass. and this block is provided with a plurality of spaced right angularly disposed grooves 14 to accommodate the segregated wires of the screen, as will be readily understood.

Referring now to the block disclosed in the modification illustrated in Fig. 6 the bottom of the block is provided with right angularly disposed intersecting grooves 14 and 15 intersecting each other approximately centrally of the block and merging into grooves lt at the sidcs of the block and at the opposite extremities of each of the intersecting grooves, the grooves 18 at the sides of the block contiguous the groove 14, merging into the relatively deep groove 1 in the upper surface of the. block while the grooves 16 contig-unis the groove 15 merge into the shallow groove 2 in the upper surface of the block. The purpose of this construction is to enabl the blocks to he fits tened to the intersecting reinforcing bars, tic wires or the like being wrapped around the intersecting portions of the reiutoiwing rods and dis ivoscd within the grooves at the sides and bottom of the spacing or holding blocks. in the construrtion of the blocks just des ribed, it will be noted that the tie wires f r fastening the reinforcing rods to one another and to the blocks are held soared from the form or framing and owing to the grooves ll he i ottom and sides of the bloclts. the plastic on is permitted to enter the grooves and solidify therein with the eti'ect to cover the wires, thereby rendering the wires invisible when the plastic mass has settled and hardened.

From the foregoing deseri 'itien taken in connection vi h the a companying drawings. the construction and manner of employing my invention will be readily understood by those skilled in the art. and while I have herein shown and -.tc1-1cribed.certain forms of my invention by 'a of illustration. it is to he understood that 1 do not confine myself to any particular arrangement of the grooves within the blocks. or to the precise details of constru tion herein described and d lineated, as modificati n and variation may be made within the scope of the claim and without departing from the spirit of the invention.

I claim:

As an article of manufacture, a block for holding the reinforcing bars of a plastic mass spa ed apart from the form or false work, said block having intersecting grooves formed in both the upper and lower faces thereof and grooves in the sides-thereof interconnecting the first-named grooves, certain of the grooves being designed to receive the bars at points of intersection of the latter, and tie wires binding the bars at the points of lHtOlStt'llOIl and wrapped about said block in the side grooves therein.

ln testimony whereof I atfix my signature in presence of two witnesses.
