UNITED STATES PATENT @OEEicEo LEMUEL BANNISTER AND LORIN kBLODGE'I, OF PHILADELPHIA, PENNSYL- VANIA; SAID BLODGET ASSIGNOR TO SAID BANNISTER.

CONDUIT FOR ELECTRIC CO-NDUCTORS.

SPECIFICATION forming part of Letters Patent No. 301,203, dated July 1, 1884.

Application led December 26, 1883. (No model.)

To aZZ whom t may concern.:

Be it known that we, LEMUEL BANNrsTEE and LoRrN BLoDGE'r, citizens of the United States, and residents of the city and county of 5 Philadelphia, in the State of Pennsylvania, have jointly invented certain Improvements in Conduits for Electric Conductors, of which the following is a specification. l

In the accompanying drawings, Figure l is Io a View of a section of conduit, and a transverse sectional view of an ice-box or refrigerator, with which the interior of the conduit is connected. Figs. 2, 3, and et are views illustrating the manner in which the Wires are sup- I5 ported within the pipes, and Fig. 5 a View illustrating the arrangel'nent of the conduitsections.

In Letters Patent N o. 282,833, granted August 7 1883, to Lemuel Bannister, an electric 2o conduit is shown and described, the construction of which we prefer to employ in our present system-that is to say, the conduit-pipe is formed in sections, and each alternate section is divided longitudinally, so that by the re- 2 5 moval of' its upper half ready access may be had to the wires. rlhe lateral connections with the conduit are also preferably made at a divided section, all of which details are fully set forth in the patent above mentioned, to

3o which reference is made.

The purpose of the present invention is to` provide an economical and practical way of supporting the wires within the large pipesections of the conduit. In the prior patent l 35 above mentioned this is done by inelosing them within tubes which are supported in partitions contained in the large pipe-sections.

Under the present invention each divided section A of the conduit is provided with one or .to more series of posts, B, on which the wires sockets are formed by flanges c e, projecting inwardly from the wall of the pipe. Vith such a construction each post may readily be removed and replaced, if desired, without disturbing the other posts, and all the posts are 5 5 at the same time held rigidly against any lateral strain. Though We prefer to employ an upper and lower socket, as shown, a single socket in the lower half of the pipe-section only may be employed, as the strain of the 6o Wire will be sufficient to maintain the posts in a vertical position.

The intermediate sectionless pipe-sections A may be provided with suitable Wire-supporting devices, or the strain on the wires may 6 5 hold them sufficiently taut so that no support will be required between the posts in one sectional pipe and the posts in the adjoining sec tional pipes.

Vith such an organization as has been de- 7o scribed any Wire may readily be reached without difficulty by removing the upper half of one of the pipe-sections. The length of these sections may, of course, be varied as will be found most convenient in putting them in 75 place in the ground.

It is desirable to provide some means for securing a dry absorbent atmosphere in the conduit, and We preferably employ an arrangement, such as illustrated in Fig. .1., in which So is shown an ice-box or refrigerator, E, having inclined hollow shelves e, on which the ice is placed and a gutter, e', that carries loff the drip pings. The air is drawn into the refrigerator through valvesf by the pump D, and is passed Si', through the pipe G into the conduit, and may be allowed to escape through exits X.

We do not herein claim any method ofl se; curing a dry absorbent atmosphere in the conduit; but We deem it Idesirable to employ the 9o method herein shown and described.

Ve claim as our inventionl. The combination, substantially as set forth, of an electric conduit, and the independ ently-supported and independent]y-removable 9 5 posts or wire-supports, arranged in a transverse series across the conduit.

2. The combination, substantially as set upper and lower sections of the pipe, which` 50l divided or formed in two parts, and n trans verse series of indepeinlently-reinovable wirei 5 sustaining posts or supports mounted in the divided conduitseetions.

In testimony whereof We have hereunto subscribed our naines this 22d dai-y of December, A. D. 1883.
