METALLIC BASE FOR POSTS.
SPECIFICATION forming part of Letters Patent No. 772,928, dated October 25, 1904. Application filed February 24, 1904:. Serial No. 194,985. (No model.)
T0 at whom it may concern.-
The object of the invention is to provide ametallic sheet of special construction which is adapted to be driven in the ground and is adapted to receive within its upper end the lower end ofawooden post. The sleeve is provided with suitable perforations for the purpose of admitting air beneath the lower end of the post, and thereby. preserving the wood. The sleeve at its upper end is provided with a turned-back edge which at one corner is cut away so that the upper edge of the sleeve may be in continuous lines while the metal constituting the sleeve is overlapped and riveted together.
The advantages incident to the use of my invention are that postsof short length may be employed, thus effecting a saving of this material.
preserved-for a great lengthof time. c The sleeve being driven into the ground, the labor of diggingpostholes is avoided; and the sleeve is rigidly embedded in the earth.
In the accompanying drawings, Figure 1 is a perspective view of the sleeve embedded in the ground with a'post located therein. Fig. 2 is a transverse sectional view of the sleeve and the lower end of the post.- Fig. 3 is a perspective view of the sleeve. Fig. 4: is a horizontal sectional view of the sleeve, and Fig. 5 is a perspective View of a corner of the upper edge of the sleeve.
The sleeve 1 is made of sheet metal, which may be formed in tubular, rectangular, or octagonal shape. The said sleeve is open at its upper and lower ends, and the upper edge of the said sleeve is bent or folded back upon itself, as at 2. The edges of the sheet constituting the sleeve are riveted together, as at 3.
The post being elevated above the ground and having its lower end ventilated is;
. from distortion.
The sides of the sleeve are provided with the perforations 4.. At the upper end of the sleeve and at a corner thereof which comes underneath at the overlapping edges the sheet is cut away, as at 5, and an incision 6 extends down into'the' sheet parallel with the edge thereof. Thus the material "between the incision 6 and the edge of the sheet forms a tongue.
serted therein, as shown in Fig. 2, and thus the upper edge of the said sleeve will have a tendency to shed the moisture away from the lower end of the post. v
In order toerect the post, the lower end of the sleeve 1 is placed upon the ground,.and a block (not shown in the drawings) is fitted into the upper end of the sleeve. By the use of a sledge-hammer or maul the lower end of the sleeve is driven into the ground until the perforations 4 are just above the surface thereof. The block above referred to receives the force of the blows and preserves the sleeve The said block is then removed, and the'lower end of the post 7 is driven into the upper end of the sleeve 1 until the extreme lower end of the post is just above the perforations f. The nails 8 are then driven through the perforations 9 of the sleeve 1 into the lower end of the post 7 and the parts are properly secured together.
By providing the cut-away space 5 the upper edges of the sleeve may be formed Having described my invention, what I I claim as new, and desire to secure by Letters Patent, is-
1. A base forposts consisting of a continuous piece ofsheet metal overlapped at its edges forming a sleeve which is of the same transverse dimensions throughout its length.
2. A base for posts consisting of a continuons piece of sheet metal overlapped at its edges forming a sleeve, the upper end of the sleeve being bent back upon itself.
