BASE-PLATE.

Application filed February 19, 1916. Serial No. 79,402.

'1 '0 all whom it may concern:

Be it known that I, CHARLES J. WILLIA us, J r., a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in Base-Plates, of which the following is a specification.

My invention relates to an improvement in base-plates, the object being to provide a solid support for vertical posts or columns, and more'particularly those that are co1nmonly used in the track construction for drykilns, the object being to provide meansto insure the lower surface being thoroughly surrounded by the soft concrete base, and permanently fastened therein.

In the accompanying drawings:

Figure l is a top view;

Fig. 2 is a bottom view; and

Fig. 3 is a section.

A, is the base casting, preferably although not necessaril round, with a central screwthreaded ori ce 1 into which the lower threaded end of the column or post 2 is screwed On the lower side, there are the inner and outer ribs 3 and 4, the former around the central orifice, and the latter at the outer edge, and the radial connecting ribs 5, 5, extending fromthe inner to the outer circular ribs.

At points say midway between ribs in the several spaces 6, surrounded by the ribs, the buttons orprojections 7, 7, are cast integral, their lower edges being preferably flush with the lower surface of the several ribs, and

. they tapering so that their lower ends are larger than their upper ends wherethey join the metal of the base. The purpose of this construction is obvious, namely that it provides a fastening means which is embedded inthe soft concrete and held fast by the latter as the concrete which has filled the open spaces 6, 6 between the ribs hardens.

- So, although the length of the ribs and buttons or projections is comparatively 7 short, they nevertheless constitute a firm and Specification of Letters Patent.

the cement, after it sets and hardens, makingit impossible to overturn the base from any amount of strain and'weight, (which is, of course, great) to which a structure of this type is necessarily subjected.

In addition to the ribs and buttons or projections, it is customary also to secure the base to. anchors 9 placed in the concrete a suitable distance below the base-plates by means of the bolts, 10, 10, inserted through. the holes 11, 11, provided for that purpose in the base-plate, nuts 12, 12, being screwed thereon to hold the baseplate in place.

In thisv way, a solid foundation is provided; and a basewhen formed in this way is easily, quickly and securely set in the soft concrete which fills in around the but tons or projections and holds the entire base secure with uniformity at substantially equidistant points in its surface;

I claim:

The combination with a concrete foundation having. fastening devices embedded therein, of a base plate adapted to be applied tion, the lower surface of the plate having integral concentric and radial ribs and buttons at intervals in the spaces between said,

ribs, the outer surfaces of which ribs and buttons are in approximately the same plane, which plane is beneath the plane of the bot tom surface of the plate, whereby space is left for the plastic concrete between the ribs and around the buttons, whereby the base is secured by both the concrete and the fasten ing devices.

' V In testimony whereof I aflix my signature.

CHARLES J. WILLIAMS, JR.
