The above are recited as examples, and are to be considered so rather than enumeration concrete, cement,

' vWith'the above and other objects in view, the invention further consists in the novel details of construction and combination of parts to be -fully described in the following specification, and then pointed out in the claims. Y

Referring to the accompanying drawings forming a part ofv this specification, and wherein like characters of reference designate similar parts throughout the several views; Figure 1, is a side elevation of an embodi ment of the invention plrior to positioning of the truss plate, Fig. 2, i ustrates the position of the truss plate assumed thereby in being positioned with respect to. the tie rods, Fig. 3, is a view illustrating the truss plate in artly emlastic com osition, ig. 4, illusisclosing the use of a ded in a trates a mo cation,

In putting theinvention into practice, we preferably employ a core member which is tubularduring its length, and which is strengthened by pouring the same full with or other plastic composi- This core Specification of Letters IPatent. Application filed June is, 1906. Serial No. 822,041.

threa ed to receive the securing nuts as trated at 8, in Figs. 1, to 4.

It will be observed that the respective tie rods are each formed of a single piece of material, which latter is preferably a strand of wire of considerable cross-section, the same being bent into U-shape at its-lower portion to thereby extend about the bottom end of the core member as shown in the drawings, the upper ends which' have been stated to be threaded being passed through the apertures 7, of the top plate 6, after which nuts 8, are applied and screwed down onto the several legs of the tie rods until the desired eliminates all slack of which the tie rods may have been possessed of. I further increase the tension on the respective tie rods by the employment of a truss plate which as shown in Fig. 3, is disposed intermediate the length of the core member, and which is of the form shown in Fig. 8, of the drawings. This truss plate is indicated by the reference character 9, being preferably of square contour and having a large opening 10, therein which rather imparts to the plate a U-sh ape contour, the width of opening 10, agreeing with that of the diameter of'the core member so The truss plate is also notched at its ends to receive the tie rods as shown at 11.

In Fig. 4, we have furt er shown the possibilities of this invention, wherein a pluralityof truss plates are 'emplo ed, arranged at regular intervals during" t e length of the core member, and being of varying sizes to agree with the angle which" the tie rods make with the'co're member. This form is especially valuable in heavy -construction where great tensile strength is desired and essential. It will thus be noted that no one point subjected to undue strain or pressure, since the reinforcement bears an equal relation to all parts of the construction in which the invention em-'I con unction with avmg thus described our invention;
