REINFORCED CONCRETE CRIBBIN G.

" Specification of Letters Patent.

Patented Mar. '7, 1916.

Application filed January 23, 1914. Serial No. 813,891.

. To all whom it may concern:

Be it known that I, CHARLES F. BUENTE, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and is a sectional view on the line IIII of Fig. 1. Fig. 3 is a plan view partially in section of one form of header. Fig. 4 is a side elevation thereof, partially in section. Fig. 5 is a side elevation partially in section of one form of stretcher. Fig. 6

is a plan view thereof with parts broken away. Fig. 7 is a sectional view on the line VIIVII of, Fig. 5 showing the stretcher in connection with a filler block. Fig. 8 is a detail perspective view of one end of the filler block. Fig. 9 is a perspective view of one of the bushings used in connection with the headers and stretchers, and Fig. 10 is a perspective view of the wire mesh which is used for reinforcing the ends of the headers and stretchers.

This invention relates to an improvement in reinforced concrete cribbing, and is designed to provide a cheap and efiicient device of this character which can readily be erected and in which the various members are interlocked with each other, so that each member will assist in bankment from sliding.

A further object of my invention is to provide'headers or stretchers having openings extending through the ends thereof in a vertical direction, and which openings are bushed from the top to the bottom of the members, together with reinforcing members embedded in the headers or stretchers which are secured or wrapped around the bushings, so that tensile stresses will be transmitted from the reinforcing members to the bushings, which will in turn transmit all of the stresses over the entire preventing an emthickness of'the headers and stretchers at the ends thereof.

A still further object of my invention is to provide suitable filler blocks which are interlocked with the stretchers, and are arranged to fill up the spaces between the ends of the headers and stretchers forming the face of the cribbing.

I am aware that it is old to build a cribbing of wooden headers and stretchers in which the headers and stretchers are secured to each other in various manners, but heretofore such structures were built of timbers, which readily decay at a point adjacent to the surface of the embankment, so that the life of the cribbing is comparatively short.

By the use of a structure such as shown and described by me, the life of the cribbing would be almost indefinite.

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 madejinthe details and construction of the different parts without departing from the spirit and scope 01f my invention as defined in the appended c aims.

In the drawings, the reference character 2 designates the stretchers' in the face of the cribbing, and 2 the stretchers which are usually located within the embankment.

3 designates the headers extending from the stretchers 2 to the stretchers 2 the ends of each header being arranged to overlap the ends of two adjacent stretchers. In my preferred construction the stretchers are each provided with an opening adjacent to each end thereof, while the headers are each not only enhance the appearance of the structure, but will also prevent dirt and sand from being washed from the embankment between the headers and stretchers.

I prefer to make the headers and stretchers similar to those shown in the drawings in which each member is provided with a plurality of metal bushings 7 whiclr extend through the members in a vertical direction from the top to the bottom thereof, and are connected to each other by means of rods 8 which extend from bushing to bushing in a longitudinal direction and are secured thereto in any manner. The members are further reinforced by means of wire mesh or any well known reinforcing material, such as shown at 9,.which extends in a vertical direction in the ends of the members and surrounds the bushings and the rods 8. The filler blocks 6 are also provided with a plurality of rods 10 extending through the structure in a longitudinal direction.

I prefer to make the various elements. at the shop or factory so that each of the members will be properly formed to meet the various requirements and in forming these members I fix the bushings 7 in theirproper positions within a mold, then secure the reinforcing elements in' position to the bushings and then fill the mold with concrete.

The cribbing is erected in the usual manner by placing a plurality of parallel rows of stretchers and then a plurality of parallel transverse rows of headers, and then another plurality of rows of stretchers on top of the headers. I then pass drift pins through the two stretchers andthe headers to secure the'several members to each other, these drift pins extending from the center of one member through the next member and to approximately the center of the next member, so that each drift pin is within the bushings of three members.

The advantages of my invention result from the provision of a cribbing formed of composite reinforced concrete having metallic bushings extending therethrough for receiving the secured drift pins and in which the tensionstresses of the longitudinal reinforcing members are transmitted to the bushings, each in turn transmitting them ers being in line with openings through two stretchers above and below said headers, and drift pins extending through said openings for securing the members to each other; substantially as described.

2. A reinforced concrete cribbing element having a metallic tube extending through each-end thereof for the reception of a securing member for securing said element to another element, and a longitudinally extending reinforcing rod hooked about the tubes and engaging the outer faces thereof, so that the tension stresses set up in the elements are transmitted to the tubes; substantially as described.

3. A concrete header for cribbing having a plurality of tubes extending through each end-thereof in a vertical direction, and a plurality of reinforcing rods hooked about the tubes and engaging the outer faces thereof, so that the tension stresses set up in the elements are transmitted to the tubes;

substantially as described.

4. A concrete header for cribbing having a plurality of tubes extending through each end thereof in a vertical direction, a plurality of reinforcing members extending from tube to tube and secured thereto, and a second vertically disposed reinforcing element in each end of the header surrounding the tubes and the first mentioned reinforce at the ends of the header; substantially as described. 7

5. A composite cribbing having a plurality of vertical rows of separate reinforced concrete stretchers and a plurality of vertical rows of separate concrete headers extending at an angle thereto, there be ing openings through such headers and stretchers, drift pins in said openings for connecting the stretchers to the headers, concrete filler blocks interposed between the tops and bottoms of some of the stretchers and the ends of the headers between sald. stretchers, and a projection and recess interlocking connection between said filler blocks and stretchers; substantially as described.

6. A composite cribbing having a plurality of vertical rows of separate reinforced concrete stretchers and a plurality of vertical rows of separate headers extending at an angle thereto, means for securing said headers and stretchers to each other, said stretchers having recesses in the top and bottom faces thereof, filler blocks between the tops and bottoms of some of the stretchers and the ends of some of the headers, said filler blocks having projections ex.-

tending into the recesses in the stretchers set my hand.
