CONDUIT CAP FOR ELECTRIC INSTALLATION.

Application filed November 1, 1919.

To alt 2071 0112 may concern:

Be it known that I, l rrnnnnn H. Vienna, a citizen of the United States, residing at New London, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Conduit Caps for Electric Installation; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact de scription of the same, and which said drawings constitute part of this application, and represent, in

Fig. 1, a view partly in side elevation and partly in vertical section of a conduit-cap constructed in accordance with my invention, shown as applied to a. shingled surface. Broken lines in this figure indicate that the mounting-arm of the bracket may be turned downward instead of upward if desired.

Fig. 2, a View of the device in front elevation.

Fig. 3, a plan. view thereof showing its carrying-arm extended by broken lines and reinforced by a brace also shown by broken lines.

My invention relates to an improved conduit-cap for electric installation, the object being to produce a conduit-cap of the type adapted to be secured to and supported by a building, a pole or other convenient means of support extraneous to the conduit-pipe itself, and also adapted to take the total strain of the scrvh're wires so as to tvoid the necessity of any other support for them. The special object of my invention is to produce a simple and cheap conduit-cap of the type described, adapted to be fitted for use in a variety of situations without any other change than varying the length of its mounting or its carrying-arm or both.

lVith these ends in view my invention consists in a conduit-cap having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claim.

In carrying out my invention, I employ an open ended angular strap-like bracket or frame comprising a vertical mounting or suspension-arm 2 and a horizontal carryingarm the said bracket being made by preference from a suitable length of heavy sheet Serial No. 334,992.

metal and the arms 2 and 3 being located at a right angle with respect to each other. The arm is perforated as at 4t for the re ccption of the bolt 5 by means of which the bracket is firmly secured to the wall of a building or to some other support extra i'ieous to the conduit-pipe 6. As shown, the said wall is indicated by shingles 7, the arm 2 being long enough to lap over two shinglesv The said arm 2 may obviously be increased or decreased in length according to mounting requirements without in any other way changing the structure of the fixture as a whole or in detail.

The carrying-arm 3 of the bracket is formed well within its outer end with a vertical, threaded opening 8 adapting it to be screwed upon the threaded upper end of the conduit-pipe 6, but it is to be clearly understood that the aid conduit-pipe is not relied upon to carry the weight of the conduit-cap and wires or cable nor to resist the strains imposed upon the fixture by the same, such weight and strains being devolved upon the suspension or mounting-arm 2 aforesaid. Upon the upper face of the outer end of the arm 3, I mount the insulating cleats or blocks 9 and 10 which are secured together and to the arm 3 by means of screws 11 passing down through them and into threaded holes 12 in the outer end of the arm. These blocks or cleats 10 and 11 are also clamped upon the cable or the wires by means of the screws 11. They are enclosed and protected by means of a sheet metal hood 13 which also covers the opening 8 in the arm 3 and hence excludes water from the pipe 6, the said hood being secured in place, as shown, by screws 14 passing through its lower outer corners and entering the edges of the arm 3 near the outer end thereof.

If desired, the arm 3 may be extended to any length without otherwise changing the conduit-cap, for the purpose of moving the opening 8 and hence the pipe 6 away from the wall to which the conduit-cap is applied, as a matter of convenience or for compliance with a local ordinance.

\Vhat I wish to particularly emphasize in connection with my present invention, is its extreme simplicity, cheapness and convenience, its taking the strain of the wires or cable from the conduit-pipe and its adaptation to the locality and requirements of its use by arying the length of one or the other or both of its arms without any other change in the fixture. The bracket may be initially made with arms of the right length or with arms ot maximum length, thus providing for cutting them do W11 to the length required by any given installation.

I claim:

In a conduit-cap for electric installation, the combination with a one-piece bracket consisting of a flat strip of Wrought metal bent transversely to form a vertical suspensioi'i-arin and a horizontal earrying'arm, the former being perforated for being secured to a stationary support, and the latter being perforated and threaded for the application of the bracket to the threaded end 01 a conduit-pipe; of Wire-insulating-andgripping means mounted upon the upper face of the outer end of the said carrying-arm, and a fol-Wardly-opening hood adapted in shape and size to protect the said means, to cover the open upper end of the said pipe, and also to clear the suspension-arm of the bracket, whereby the total strain or the service-Wires is imposed upon the bracket and removed from the conduitqvipe.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses. V
