POST AND POLE AND BASE THEREFOR.

Specification of Letters Patent.

Patented Sept. 12, 1911.

Application filed May 26, 1909, Serial No. 498,583. Renewed February 13, 1911. Serial No. 608,397.

To all whom it may concern:

Be it known that I, MAURICE HENRY MURRAY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Posts and Poles and Bases Therefor, of which the following is a specification.

This invention relates to posts and poles and bases therefor; and it has for its object to provide improvements directed at the construction, organization, connection and installation of telegraph, telephone and other poles or posts and bases for the same, which improvements shall be superior in point of simplicity and inexpensiveness of construction and organization, facility of installation and repair, and durability, and which will be generally superior in point of efficiency and serviceability.

The invention is particularly adapted for the continuation in use of poles or posts, or the upper or major portions of the same, after the base or lower portions of the same have become weakened, rotted or destroyed under action of the elements and the earth or other material or substances in which the poles or posts are set up.

Because of the rapid partial or total destruction of posts or poles, at the lower ends of the same, where in direct contact with the earth, it has been customary to remove and discard the entire post or pole after service of the same for a limited period of time. In the case of telegraph, telephone and other transmission line poles, which are of considerable size and initial cost, the discarding of the poles after a brief period of service, because of deterioration and decreased deficiency of the lower implanted portions of the same, has resulted in heavy fixed charges for line maintenance equivalent to substantial losses. Such losses are rendered unnecessary, and are approximately obviated by the utilization of the improvements constituting the present invention, according to which I provide a base having long life, which is substituted for the deteriorated lower portion of the post or pole; such lower portion being removed for substitution of the said durable base.

The present invention constitutes a fur ther development in the art concerned, with relation .to the subject matter of a prior patent for a pole base, issued to me September 3, 1907, No. 864,854; and certain of the features in the following disclosure constitute the subjects of an application for Letters Patent for pole bases, filed by me February 6, 1908, Serial No. 414,634.

The present invention consists in the novel provision, construction, .combination,

association and relative arrangement of parts, members and features, all as hereinafter described, shown in the drawing, and finally pointed out in claims.

In the drawing: Figure 1 is a side elevation, partly in section and partly broken away for clearness of illustration, of a pole and base therefor, provided with and em bodying the improvements constituting the present invention; Fig. 2 is a horizontal transverse sectional view of the same, taken upon the line 2-2, Fig. 1, and looking in the direction of the appended arrows; Fig. 3 is an enlarged detail view, partly broken away and partly in section, of a feature of the construction and organization shown in Fig. 1; and, Fig. 4 is a detail transverse sectional view taken upon the line 44, Fig. 3,.and looking in the direction of the appended arrows.

Corresponding parts in all the figures are denoted by the same reference characters.

Referring with particularity to the drawing, A designates a pole or post, or the upper portion of the same, and B designates a base for the same; the base comprising the implanted portion of the entire structure whereof the pole or post A is the superposed portion; and said pole or base being constructed or organized according to the present invention.

0 designates reinforcement for the base B, and D designates connection means for attachment of the pole to the base, parts of said reinforcement and attachment means being common to both of the same.

E designates a brace adapted to maintain the pole A in proper upright position and to assist the same in the resistance of the stress imposed thereupon in service. The brace E includes withinit-s organization adjusting means 6, which are electrically insulating, and whereby the operative condition of the brace may be regulated.

A particular preferred form of provision, construction, combination and operative association and connection of parts, members and features embodying the invention is as follows :-The reinforcement C is firmly embedded in the mass, of the base body 5, which latter consists of molded concrete; said reinforcement consisting of two spaced looped metallic straps or bars, 6 and 7 remember 9 is disposed adjacent to the upper:

portion of the base body 5, being connected, as at 10, with the portions of the looped members 6 and 7 which cut the plane within which said annular member 9: lies. The member 9 is also embedded within the concrete base body 5.

The upper portion of the looped reinforcement 'members 6 and 7 project above the base body 5 as at 6* and 7 respectively, and embrace the lower end portion of. the pole A, beingconnected therewith, as at 11, thus constituting the connection means D. One

' portion, 7 of the reinforcement member 7, V is broken to include a hinge 12 whereby the pole A may be hingedto the base B.

The brace E is connected at its lower end wlth the reinforcement C, and the member 8 thereof,-.by a curved tie rod 13 which is firmly embedded in the base body 5, the lower end thereof being looped about the upperend of the bolt 8, as at 14, and the upper end thereof being formed into an eye 15. which projects above the base body.

The brace E comprises'two flexible members 16 and 17' which are joined by the adjusting means 6, as at 18 and 19, respectively. The upper end of-the member 17 is connected with a shackle or bolt 20 which is connected with the post or pole A, at a predetermined point about the lower end thereof; and the lower end of the member 16 is connected with the eye 15 upon the tie rod 13.

The brace E is bowed outwardly from the or rope. 1

p The adjusting means 6- comprise an elongated insulating body 25, preferably consisting-of wood saturated or impregnated with paratiin, the body being squared to fit a wrench or other implement for manipulating the same. Oppositely threaded rods 26 and 27 enter the opposite ends of the body 25, each being provided with outer end eyes 19 and 18 whereby the lower end of the brace member 17 and the upper end of the brace member 16 are respectively joined with the adjusting means 0 as above stated. Insulating plates 28 and 29 are fitted against the respective ends of the body 25,

surrounding the rods 26 and 27 respectively,

and are held in place by lock nuts 30 and 31 on the respective rods 26 and 27. Lateral chambers 32 are formed in the body 25 respectively communicating with the bores which receive the rods 26 and 27, and through said chambers 32 are passed nuts 33 which are held firmly in said chambers in position to act as bearings for the threaded rods 26 and 27. The chambers 32 are sealed with wax or other insulating medium 34 after the introduction of the nuts 33. Further to secure the lower end of the brace E against displacement, due to tendency of the tie rod 13 to spread laterally and crack or split the base body 5, I provide a clamp or clevis 13 which unites the upper eudportion of the tie rod 18 and the reinforcement member 7, preferably above the annular reinforcement member 9. The clamp 13 is embedded in the base body 5.

The operation, method of use and advantages of the improved post or pole and base therefor, together with the attendant parts and features constituting the invention, will be readily understood from the foregoing description, taken in connection with the accompanying drawing and the following statement :-The base B is implanted in the desired position and the pole or post is superposed thereupon, the connection means D or any equivalent or suitable substitute, being utilized to attach the butt end of the poster pole firmly to the base. The annular member 9 of the reinforcement C rigidly joins the upper portions of the reinforcement members 6 and 7, adding stability and positiveness to the holding function of the connection means D which in part comprise said reinforcement members. The member 16 of the brace E is then connected with the eye 15 at the upper end of. the tie rod 13, which latter. is firmly embedded in the base body. 5 and anchored to the bolt 8 of the reinforcement C, as at 1 1.. The member 17 o-fthe brace E is joined with the pole or post at an upper portion of the same, by means ofthe shackle or bolt 20. The bracket or prop, f receives the member 16 adjustably upon its roller 24:; and the entire brace may be slackened or tautened by manipulation of the adjusting means 6 which connects the upper end of the brace member 16 and the lower end of the brace member 17 and acts as a turnbuckle. The pole and base are thus supplementally connected by the brace E, subject to variation of tension or operative stress of the brace, and the service stress to which the pole is subjected is variably opposed and equalized by the resistance of the brace. The insulating body of the ad justing means 0 effectively isolates the upper member 17 of the brace E from the lower member 16 thereof, preventing the objectionable selection of the brace as an electrical path to the base B through the lower member 16. The organization of the adjusting means 6, with respect to the insulating nature thereof, by utilization of the impregnated wooden body 25 within which the opposed ends of the rods 26 are received in spaced relation, results in increased combined efficiency and economy as over means to the same end heretofore employed; and the insulating function is increased by the employment of the insulating plates 28 and 29 and the plastic insulating seals 34.

The entire structure and organization is eiiicient and positive in service; and is capable of production, installation, maintenance, adjustment and repair at low cost and with extreme convenience and facility.

Having thus described my invention, I

claim and desire to secure by Letters Patent 1. A base for posts or poles having an internally located reinforcement consisting of spaced members, a rod connecting said members, a post or pole upon the base, a brace between the post or pole and the base, and a tie rod connecting the brace and said con-, necting rod.

2. A post or pole, a base therefor having a reinforcement, a brace between the post or pole and the base, a tie rod connecting the brace and the reinforcement, and a clamp connecting the tie rod and the reinforcement.

3. A post or pole, a base therefor having an internally located reinforcement, a brace between the post or pole and the base, a tie rod connecting the brace and the reinforcement and in part internally located in the base, and a clamp internally located in the base and connecting the tie rod and the reinforcement.

In testimony whereof, I have signed my .name to this specification in the presence of tWo subscribing witnesses.

MAURICE HENRY MURRAY. Vitnesses RAYMOND Ivns BLAKESLEE, FRED. A. MANSFIELD.
