To all whom t may concern:
Be it known that l, CHARLES F. BUENTE, a citizen of the United States, residing at Pittsburgh, Allegheny county, Pennsylvania, have invented a new and useful lmrovement in Reinforced-Concrete Cribings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a sectional vie'vv on the line A--A of Fig. 4.

This invention relates to an improvement in concrete cribbin and is designed toprovide a' cheap and e cient device of this character in which the various parts can be built at a factory and shipped to the point at which it is to be erected, and in which the various members are so interlocked with form ` each other that none of the headers can slide longitudinally with relation to the other headers. l A. n
Another object of in invention is to so form headers and stretc ers that cribbing of any size can be built from one form of i header and one form of stretcher, so that it titi' will not be necessary to design molds for headers for did'erent sized structures.
Still another object of my invention is to provide aller members for the front of the cribbing which are interlocked with the headers and stretchers surrounding the space in which the filler is inserted.
The precise nature of my invention will be best understood by reference to the accompanying drawings, which will now be described, it being premised, however, that various changes may be made in the details of construction and general arrangement of the parts without departing from the spirit and scope of my invention as defined in the appended claims.
Referring to Figs. 1 and 4 of the drawings, the reference character 2 designates a plurality of stretchers in vertical rows, each of said rows being formed of a plurality of i courses of stretchers. ln these drawings each stretcher is provided with a longitudinal roove 3 in the bottom thereof, and a longitudinal tongue 4 along the top thereof. 5 are headers which are provided with transverse tongues 6 on the upper surfaces thereof and at each end, while on the lower surfaces thereof immediately below the tongues are transverse grooves 7 for'the reception of the tongues on the stretchers, or tongues on headn ers 1n adjacent courses 1n the rows of stretchers.
Each of the headers and stretchers is provided with vertical openings for the reception of anchor rods 8 which extend upwardly from a foundation 9.
ln the construction shown in Figs. 1 and 4 the foundation is first erected,V and the anchor rods 8 placed in proper position, as indicated in Fig. 1. The lower headers indicated at a and b along the entire length of the structure are then placed in position, and headers are placed at c along the entire strctlre to interlock with the headers a an Filler blocks 10 having tongues 11 at their ends, and tongues 12 along their upper surfaces are then placed in position etween the stretchers a, a, the tongues 11 on the 'ends thereof engaging vertlcal recesses in 'i the headers, as indicated in Fig. 6. Stretchers 2 are then placed above the headers a titi titi
and the filler blocks 10, as indicated at e in with the art that as the various courses are.
laid up the openings through the headers and stretchers through which the anchor rods extend are illed up with concrete to entirely flll the space between the walls of the openings and the anchor rods.
In Fig. 2 I have shown a structure similar to that shown in Fig. 1, but in this case the bodies of the headers extend at an angle to the horizontal, so that the two ends thereof are in different horizontal planes.
In Fig. 3 I have shown a structure similar to that shown in Fig. 1, butin which the headers and stretchers are placed at an angle to the horizontal and vertical, respectively.
In Fig. 5 I have shown another form, in which I have shown headers of different lengths. In this construction the headers extend from back to the front of the structure, and in which the headers 5a are provided .with projections 13 which engage shear blocks 14 interposed between the projections 13 of adjacent headers, and which are arranged to resist any sliding movement of the headers relative to each other under pressure of the lill or earth.
In the construction shown in Figs. 1 to 4,
inclusive, the longitudinal rows of stretchers are laid up in courses which alternate with headers extending at right angles thereto and interlocked therewith. The
'headers extend from one row of stretchers to the next row of stretchers. The rear rows of stretchers are in different horizontal planes, as well as in different vertical planes, so that the headers between two adjacent rows of stretchers alternate with the stretchers extending from one of said rows to the next row of stretchers, the arrangement being such that the upper rows of stretchers are provided with supporting columns beneat the points of intersection of the stretchers and headers by means of the alternate headers.
In former cases, the headers extended from one row of stretchers to the next row of stretchers in the same horizontal plane, so that the upper headers were considerably shorter than the lower headers. In constructions of this character the entire load of the upper rows of stretchers were supported on one of the headers, so that there was danger of said header fracturing under the load, as there are no supports providedv for said headers below the intersection of the headers and stretchers in the upper rows, which extended to the foundation of y the structure.
In structures, such as shown in' Figs. 1 to 4, a support is formed by the alternate headers, while in structures such as shown in Fig. 5, a support for the headers is formed by the shear blocks.
In Fig. 5 the lateral movement of the headers relative to each other is prevented by means 4of the shear blocks. t
The advantages of my invention result from the provision of a cribbing-formed of a plurality of headers and stretchers, in which the various headers are interlocked with each other and with the stretchers so that one header cannot move or lslide relativeto another.
1. A concrete cribbing having longitudinally extending rows of stretchers, and transverse rows of headers interlocked therewith, one ofthe rows of stretchers being in a diiierent horizontal and different vertical plane than another row of stretchers, the stretchers in the different rows resting on headers, and supporting members between adjacent headers 1n the same rows below the highest row of stretchers and below the oint of intersection of the stretchers and headers to form a support for said row of stretchers and the headers between said stretchers; substantially as described.
2. A concrete cribbing having a longitudinal front wall built up of a plurality of courses of stretchers, a plurality ofrows of headers extendin at right angles thereto, each row of hea ers having a plurality of courses which alternate with the different courses of stretchers, a plurality of longitudinal rear walls built up. of a plurality of courses of stretchers alternating with the headers and extending parallel to the front wall, the rear walls being in different horizontal and diierent vertical planes and supporting members for the upper walls 'between the headers below said walls, substantially as described.
3. A concrete cribbing having a longitudinal front wall built up of a plurality of courses of stretchers, a plurality of rows of headers extending at right angles thereto, each row of headers having a plurality of courses alternating with the different courses of stretchers, a plurality oi longitudinal rear walls built up of a plurality of courses of stretchers alternating with the headers, the rear walls being in diierent horizontal and diierent vertical planes, each of the headers only extending from one wall to the next wall, some of the head' ers in each row alternating with other headers in the same row, so that one end each of such header forms a support for one end of another such header, and thereby forms a headers extending at right angles thereto,v each row of headers having a plurality .of courses alternating with the different courses of stretchers, a plurality of longitu` dinal rear walls built up of a plurality of courses of stretchers alternating with the headers, the rear walls being' in different horizontal and dierent vertical planes, each of the headers extending from one wall to the next wall, the headers between two 15 walls alternatin with the headers between one of said wal s and the next wall; substantially Vas described.
In testimony whereof, I have hereunto set my hand.
