. 3 Clai1ns.. (Cl:1"74 81) The following specification discloses in detail an invention in improved electrical service masts for connecting buildings with distribution lines.

With the advent of one story dwellings such as bungalows, and the so-called ramblers and ranch houses, it is impossible to find a side wall sufficiently high to receive a bracket for the service wires. In every instance the walls are so low that direct attachment of the bracket will-bring the wiring too close to the ground to permit compliance with electrical requirements. The attachment of a vertical extension or mast to the sloping roof is awkward, expensive and inefiicient.

This invention provides for a mast which will be readily mounted upon the side wall of a dwelling and can extend sufficiently high to bring the service wires in at the proper distance from the ground. It will also be adjustable for the direction from which the service wires come.

One object of my invention is to provide a service mast which may be mounted on a one story structure and provide adequate height for the wiring,

Another object of my invention is to provide for an angular adjustment of the insulating spools according to the needs of each installation.

A further object of my invention is to provide for a series of two or more insulating spools with adjustable means for mounting upon a mast of circular cross section.

A still further object of my invention is to provide a mast through which the service wires may be led without exposure to wetness or dampness.

Numerous other advantages of my invention will be recognized from the following description of the preferred form of my invention as illustrated on the accompanying drawings in which:

Figure 1 is an enlarged side elevation, partly in section, of the service mast itself, and

Figure 2 is a reduced side elevation showing the mast as installed on the side wall of a dwelling and supplying connection with the service lines.

Briefly described, the invention consists in utilizing a tubular mast of desired length with suitable fittings at each end to receive the line wires and also provided with an adjustable insulating bracket.

In Figure 2, I have illustrated a fragmentary side view of a dwelling 3, the roof 4 of which is too low to permit direct attachment of a wire bracket.

The side wall of the dwelling 3 carries a bracket 5 providing an upper arm 6 and a lower arm I.

Beneath the bracket is a fitting 8v by which the service wires are brought through the side wall of the building 3.

The service mast is constructed from a metal pipe or the like 9, preferably round in cross-section of any suitable length, which supplies the necessary height for supporting the wire bracket.

The lower end of the pipe or mast 9 passes through two rings l0 and II. These rings have threaded extensions I2 and [3 respectively by which they are bolted to the upper and lower arms 6 and I of the bracket 5.

Tighteningbolts Hand i5 pass through the rings l0 and II respectively and serve to hold the mast 9 in firm position.

The upper portion of the mast 9 carries a plurality of loose collars l6, l1 and [8. Each collar has a locking bolt l9 by which the collar is clamped in the desired position angularly of the mast 9. U-shaped holders 20 are held by each collar 16, H and I8 opposite the clamping bolts l9.

Holders 20 are in vertical alignment and connected by a common rod 2| passing through the open ends of each holder. The rod has a head 22 resting upon the upper holder 20 and a suitable locking means, such as cotter pin 23, engaging the end of the rod 2| below the lower holder 20.

The usual spool insulators 24 are carried by the rod 2| within the open arms of the holders 20.

Reducing fittings 25, 25 are screw threaded on the opposite ends of the mast 9. Washers or gaskets 26 are clamped by the fitting 25 against the ends of the mast 9 to prevent seepage of water through the joints.

The upper fitting 25 carries a screw threaded pot-head 21, the open end of which extends downwardly in suitable position above the upper holder 2!].

The lower fitting 25 is fixedly received in the member 8.

By the above arrangement, the line wires 28 are brought in substantially horizontally and connected independently to the insulators 24. Cables 29 connect with the line wires 28 and pass upwardly in the pot-head 21. Passing through the pot-head and mast, these service wires then enter the building through the fitting 8.

It will thus be seen that I have provided a mast which serves to raise the bracket for the service wires a distance suflicient to comply with electrical regulations regardless of the lack of height of the building itself.

Additionally, I have provided adequate means for preventing the seepage of moisture into the mast from either end. It will also be observed that the wire receiving bracket has a plurality of spools in alignment and independent clamps on the mast so that the direction of approach from the line wires can be changed without disturbing the fastening of the mast to the dwelling.

The above arrangement of parts is economical in manufacture, and easy to assemble. It can be installed by unskilled labor and lends itself to variationdepending upon the .buildingio. which it is applied.

I have illustrated the invention in the preferred form for the purpose of example, but it will be.

apparent that minor details of structure, proportions and material, may be varied withoutideparts ing from the scope of the invention.asl set. out.

in the following claims.

What I claim is: 1. A service mast comprising a tubular. meme ber, means for attachingthe member toa build-' ing support, a pot-head on the upper end of the member; a plurality ofhold'ers; a. 8330011 insulators in: each. holder; common; holding rod threaded through the insulators,andholdersg. and a; collar for'i'eachholder='clamped independently orr the; member; and: adjustable relative to? the other: collars.

2;v A service: masti comprising a tubular: memi-tber;v a pair. of rings for, attaching the: member to a. building support, at pot-head: ou the; upper end of; the: member, a plurality. of: holders; a spool insulator: in each: holder; a: common holding rod threaded. through; the insulators; and holders-,aand' a collar for: each holder clamped'in- 4 dependently on the member and adjustable longitudinally of the member relative to the other collars.

3. A service mast comprising a tubular member, a pair of rings for attaching the member to a building support, a screw threaded coupling on each end of the member, a gasket for each coupling, a pot-head on the upper coupling, a plurality of holders, a spool insulator in each. holder, a common holding rod threaded through the insulators andholders and a collar for each holder clamped independently on the member and adjustable longitudinally of the memberreiative to the other collars.
