BAR SUPPORT.

Application filed March 23, 1927. Serial no. 177,148.

It is also an object of this invention to' provide bar supports of substantially the same construction, one of said supports adapted to support a plurality of bars in parallel relation arranged to permit the same to support bars positioned at right angles to one another.

It is furthermore an object of this invention to providea bar support for use in connection Wi'h concrete road construction work, said bar support is constructed of metal and has pins or spiked ends adapted "to be driven into the sub-grade a predetermined distance to support a plurality of reinforcing bars or rods in proper spaced 'relation above the subgrade to. serve as a re inforcing framework for the concrete forming the road.

Itis an nnportantobject of this invention toprovide an nnproved and simplified form of metal bar support adapted for use in concrete road construction, work, said support adapted to hold a plurality ofreinforcing rods in parallel relation and at right another at a; predetermined grade, said distance feet integrally formed near the lower "spiked ends of the support. v

Other and further important objects of this invention will be apparent from the dis closures in the specification and the accompanying drawings.

i This lnventlon (in a preferred form) is illustrated in the drawings and hereinafter I bar'supp o'rt A comprises a s'piralb1g'ht or more fully described.

On the drawings: Figure 1 is a fragmentary portion of the sub-grade of a road under'construction hav ing reinforcing bars positioned thereabove while the other support is the upper surface of the subbeing determined by and held in a predetermined relation by means "of improved bar support-s embodying 1 the princ'iples of this invention.

Figure '2Iis an enlarged sectional view taken on line II-+11 of Figure l, and illustrating the "side elevation 'Of 'one of the "bar supports, which is adapted to hold bars positioned at right angles to one another.

Figure 3 is an enlarged sectional view taken on line {IL-III of Figure 1 showing another felevatijonal' View of the bar support illustrated in FigureQ. I Figure 4 is a developed plan view of the bar support illustrated inFigures 2 and Figure '5 is an enlarged sectional view taken on line V -V of Figure 1 illustrating an enlarged elevational view of second form'of bar support adapted to support bars in parallel relation only.

As shown on "the drawings: The reference numeral 1 indicates the subgrade of a concrete road having a reinforcing framework supportedin position there:

on. The reinforcingframework comprises" a pair of parallel bars or rods 2 which are posltioned to run longitudinally of the road, anda pair of parallel bars or rods 8 -p'ositransverse bars 3 is a majorreinforcing bar 4 of greater diameterthan thediaineter of themin'or reinforcing bars? and For the purpose of properly supporting stantially the sameconstruction with-the exceptlon' that thesu port A is adaptedto 'fhold bars posltionedfat *rightyangles to one another, while the support is adapted to hold bars in parallel relation only.

Referring now to Fgures'Q, 3 and the looped Yniid dle portion ,5 through with the major or large reinforcing barn is adaptedto be pro ected. Integrally formed oneach so tioned transversely of the roadandatri-,ght i angles to the bars 2. Also positioned tr'ansv 'Versely of the road between andjabove the is reinforcing barsvin spaced parallel relation tion comprising flanges 6 and 7. The lower end of each leg is tapered to afford a spike 8 of angle construction formed by cutting the material forming the lower ends of the leg flanges 6 and 7. Integrally formed on each leg flange 7 is a stop orfoot 9, which is bent inwardly, as clearly illustrated in Figure 2. The two feet 9 of each of the bar supports are adapted to act as stops for limitingthe extent to which the spikes 8 are to be driven into the sub-grade 1. Each of the leg flanges 7 is provided with an inclined notch or pocket 10 through which the reinforcing bars 2 are adapted to project in parallel relation substantially at right angles and below the major reinforcing bar 4;. .Struck from each of the leg flanges G is a retaining strap or hook 11 which is adapted to be directed upwardly and bent around one of the rods 2 to hold thesame locked in position in the lower end of its respective notch or pocket 10.

The bar support B illustrated in Figure 5, and shown in position in Figure 1, is constructed substantially the same as the bar support A with the exception that the feet or stops 9 are directed outwardly instead of inwardly. Attention is also called to the fact thatthe bar support B has the middle portion the 'eof bent in the form of a loop that will receive the major reinforcing bar 4 above and parallel tothe minor reinforcing bars 8.

It will thus be noted that the bar support of the type A is adapted to support reinforcing bars in spaced relation at right angles to one another, while the bar support ofthe type B is used for supporting only. p The improved bar supports of the types I A and B are adapted to be used, as illustrated in Figure 1, with the spiked, portions 8 of said supports adapted to be driven into the foundation or sub-grade a distance determined by the feet or stops 9. lVith the bar supports secured in place the i ' einforcv ing bars 2, 3, and 4 may be inserted in their spaced relation, as illustrated in the drawings, with the major or larger reinforcing bar projectingthrough the looped or light portions 5 of the bar supports, while the smaller or mlDODIBlII'fOTCHlg bars 2 and 3 arepositioned at right anglesto one another and project through the respective notches I orpockets .of the bar supports. After the bar supports and the reinforcing bars are properly positioned, as illustrated and de scribed, to form a reinforcing framework above the subgrade or foundation of the road, the concrete is poured around the reinforcing framework to completely "imbed the same. c

p I am aware that manychanges maybe made, and'numerous details of construction said legs tapered to form spikes and having inclined bar supporting notches therein, and retaining-straps struck "from said legs and adapted to be bent in the form of hooks to serve as retaining means for holding reinforcing bars in said notches. 7

2. A bar support comprising a pair of divergingangle legs having the lower ends thereof tapered to afford spikes, stop members struck from said legs, sald legs havlng rod receiving notches formed therein, retaming straps struck from said legs for holding reinforcing bars in said notches, and

a looped portion connecting the converging ends of said legs to afford a support for another reinforcing bar.

3. A bar support for use in concrete construction work, said support comprising a pair of diverging legs having bar supporting notches formed therein, retaining straps struck from said legs adapted to be bent to hold reinforcing bars locked in said notches,

a looped portion connecting the converging ends of said legs and adapted to serve as asupport for another reinforcing bar, and feet integrally formed on said legs at a distance from the lower ends thereof to afford stop means for limiting the distance said legs are to be driven into the ground.

4. A concrete road bar support com rising a spiral loop,angle legs integrally ormed on the ends of said loop and projecting outwardly away from one another, each of said legs having a bar supporting notch formed in one 'of' the flanges thereof,a retaining strap integrally struck from the other flange of each of. said legsand adapted to be bent to serve as a retaining means for holding a bar in said notch, spikes integrally formed on the lower ends of said legs and adaptedto be driven into the ground, and stop members st-ruck from said legs for limiting the distance said legs are to be driven intothe ing said legs and affording a support for another reinforcing bar.

6. A bar support comprising a pair of diverging legs the outer ends of which are tapered to permit the same to be easily driven into the ground, a bight portion integrally connecting the converging ends of said legs and affording a bar support, and means formed on said legs for holding additional bars supported in spaced relation with respect to the bar supported by said bight portion.

7. A bar support comprising a pair of diverging legs, means formed thereon for sup-' porting a pair of reinforcing bars in parallel relation, and a bight portion connecting the converging ends of said legs and adapted to afford a support for an additional reinforcing bar in spaced relation With respect to said parallel reinforcing bars.

bight, an angle leg integrally formed on each end of said bight With the lower end of said leg tapered to aflord a spike, each of said legs having one of the flanges thereof provided with a bar supporting notch, and a stop member and a retaining member intapered angle legs, 8. A bar support comprising a spiral tegrally formed on the other flange of each of said legs with said retaining member adapted to hold a bar locked in said notch, While the stop member serves as a means for limiting the distance the leg is to be driven into the earth. I a

9. A bar support comprising a pair of leg members, means formed thereon for holding a pair of reinforcing bars in spaced relation, and means resiliently connecting said legs to afford a support for holding an additional reinforcing bar in spaced relation to said first mentioned reinforcing bars.

10. A bar support comprising a pair of means thereon for supporting a pair of reinforcing bars in spaced relation, and spiral means connecting said legs inoffset relation and adapted to afford a support for an additional reinforcing bar.
