PROTECTIVE BASE FOR POLES Filed July 2, 1956 a 1N VENT OR.

ATTORNEYS Patented Dec. 28, 1937 UNITED STATES PATENT vOFFICE 1 Claim.

This invention relates to improvements in protective bases for poles and the like.

The principal object of this invention is to provide means to protect that portion of the pole or post which is embedded in the ground.

A further object is to provide means whereby the lower end of the pole or post may be ventilated and any accumulation of water about the base of the pole or post may be withdrawn.

A further object is to produce a device of this character which is economical to manufacture and simple to install.

A further object is to produce a base wherein the pole may be inserted and withdrawn without disturbing the base.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a vertical cross section of my inven-V tion showing a portion of a post positioned therein; v

Fig. 2 is a cross sectional view taken on the line 2--2 of Fig. 1;

Fig. 3 is a modied form of my invention;

Fig. 4 is a cross sectional view taken on the line 4-4 of Fig. 3; and s Figs. 5 and 6 are side elevations partly in cross section of two forms of Ventilating pipes.

Fence posts, telegraph poles, and other forms of wood supports are often embedded in the ground. The result is that due to the dampness that portion of the pole in the ground rots or is eaten away by insects. I have, therefore, devised means for protecting that portion of the pole or other wooden support in the most economical manner.

In the accompanying drawing wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a pole, such as a telegraph pole which has its lower portion 6 positioned beneath the ground line 1. My invention consists in surrounding the pole with a concrete block 8, having a bore 9 into which is inserted the pole. At II I have shown a plurality of grooves extending parallel to the sides of the base 6 and beneath the bottom of the pole. These grooves communicate with a. sump I2. In order to remove any moisture (Cl. .Z0-100) which may accumulate in the sump I2, Ihave provided pipes I3 and I4 having their lower ends opening into the sump I2, and having their upper ends provided with downwardly extending spouts as shown at I6 and Il respectively. Removable caps may be provided as shown. at I8. 'In the modied form as shownk in Fig. 3 I have eliminated the grooves II and provided the pipes I3 y and I4 with goose neck ends I9.

The result of this construction is that periodically I may attach a suction apparatus to either the spouts I6 or Il and withdraw any liquid which may be in the sump I2.

The same is true of the modied form. 'In the forms shown in Fig. 1, by removing one of the caps I8, I may in-Z troduce tothe bottom of the pole, if desired, a preservative which will 'further assist in protecting the Vwood below the ground. If desired, the bore 9 may be tapered slightlyso as to receive the tapered end of a pole and with this construction it would be possible to easily remove the pole without disturbing the protective base.

It will be obvious from this construction that there will be a complete circulation of air for the purpose of ventilation, through thespouts I 6 and Il down through'the pipes I3 and I4 into the sump I2 and thence upwardly through the plurality of grooves II.

The numeral 2| designates angular ports formed in the block 8, adjacent the top thereof, to thus permit ventilation and circulation of air from the exterior of the block through the ports 2l, thence through the grooves I I to the sump I2.

It is to be understood that the form of `my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material,

size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim. i

I-Iaving thus described my invention, I claim:- In a device of the character described, a molded base having a vertical bore extending thereinto, a sump communicating with said bore, pipes positioned in said molded base and having their lower extremities communicating with said sump and having their upper extremities exposed whereby moisture in said sump may be withdrawn therefrom.
