To all whom, it pea/y concern: 7

Be it known that I. CHARLES E. ZIMMER- MANN, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Bases for Pillars, &c., of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The object of this invention is to provide a strong and durable base for a pillar or post, to which it shall be securely fastened to allow it to be erected simultaneously therewith and retain its requisite position thereon; and the object is, furthermore, to provide a base which shall protect the bottom of the superimposed pillar or post from moisture and decay; and to that end the invention consists in the novel construction of the base and its attachment to the pillar or post hereinafter described and claimed.

The invention is fully illustrated in the annexed drawings, in which- Figure 1 is a top plan view of my improved pillar-base. Fig. 2 is a side view of the same. Fig. 3 is a vertical transverse section on the dotted line XXin Fig. 1 with the bottom portion of the pillar secured to said base; and Fig. 4 is an inverted plan view.

Similar letters of reference indicate corresponding parts.

My said improved base consists of a metal casting A, the bottom portion of which is preferably square and forms the margin of a cavitya, formed in the under sideof the casting. The corner portions of said margin constitute the main bottom bearings 72 b of the base. In the center of the bottom of the cavity a is a plate, which serves as an auxiliary bottom bearing 0 and which is in the plane of the aforesaid main bearings 71 Z). The said auxiliary bearing 0 is sustained in position by means of braces (Z (Z, connecting said bearing to the top portion of the casting and formed integral therewith, as shown in Fig. 3 of the drawings. The top of the casting is formed with bearing 6 for the pillar P and with an opening f concentric with said bearing and extending into the cavity a.

The top portion of the casting A is perforated, as shown at 2", for reception of screws 0, which attach it to the pillar P. The bottom portions of the casting are provided with holes 3' for reception of screws 0, by which it is fastened to the foundation, as shown in dotted lines. The bottom of said pillar or post is provided with a tenon t, which occupies the opening f, and thus confines the pillar in its central position on the base. To protect this tenon from moisture and decay, I form the walls of the metal base A with ventilatingopenings h in the bottom of said walls. The air entering through these openings and circulating in the cavity protects the tenon t, as aforesaid.

To prevent water from lodging under the corners of the base A, I form the bottom thereof with dams Z Z, extending from the ends of each ventilating-opening it directly to the adjacent ends of the succeeding ventilating-opening, as shown in Fig. 4 of the draw ings.

What I claim as my invention is 1. A pillar-base consisting of a metal casting formed with a cavity in its under side, main bottom hearings on the marginal portions of said casting, and an auxiliary bottom bearing in the aforesaid cavity.

2. A pillar-base consisting of a metal casting formed with a cavity in its under side, main bottom bearings on the marginal portions of the casting, an auxiliary bottom bearing disposed in the center of the aforesaid cavity, and braces extending from said auxiliary bearing to the top portion of the casting as set forth.

3. A pillar-base consisting of a metal casting formed with a cavity in its under side, main bottom bearings on the marginal portions of the casting, an auxiliary bottom bearing disposed inthe center of the aforesaid cavity, and braces attaching said auxiliary bearing to the casting as set forth.

4. The combination of a cast-metal base formed with acavity in its under side, an opening in the top of said base, ventilating-openings extending through the bottoms of the marginal portions of the base, dams extending from the ends of each of said ventilatingopenings directly to the adjacent ends of the succeeding ventilating-openings, and a pillar or post formed with a tenon projecting from ing-openings, a pillar or post provided on its the bottom thereof and occupying the aforebottom with a tenon occupying the aforesaid said top opening as set forth and shown. top opening, screws passing through the top 5. The metal base formed with a cavity in of the base and attaching said base to the pil- 5 its under side, an opening in its top, an auxl lar or post, and screws passing through the iliary bottom bearing disposed in the center bottom of the base and fasteningit to its founof the cavity, braces attaching said auxiliary l dation as set forth and shown. bearing to the top portion of the base, ven- CHARLES E.
