OUTLET-E001) FOR CONDUITS.

Specification of Letters Patent.

Patented Got. 26, 1915'.

Application filed March 24, 1811. Serial Ho. 616,554.

To all whom it may concern:

Be it known that I, TILMER M. Venn, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Outlet-Hoods for Conduits, of which the following is a specification.

One object of my invention is to provide an attachment for the end of a conduitdesigned to receive current conducting w'"es or cables, which shall be conveniently applicable to such conduit even though this extends immediately adjacent to or practically in contact with a plane surface such as a wall.

I further desire to provide an outlet hood of such construction that in addition to being conveniently applied to the end of a conduit, it shall efiectually prevent the en? trance of water, snow, etc., to the same; it being especially desired that the device shall be inexpensive in construction and capable of being quickly applied without requiring to be bodily turned.

These objects and other advantageous ends I secure as hereinafter set forth, reference being had to the accompanying drawings, in which Figure l, is a side elevation illustrating my invention as applied to a conduit run immediately adjacent a vertical wall; Fig. 2, is a vertical section of the outlet hood shown on a smaller scale in Fig. 1; Fig. 3, is an inverted horizontal section taken on the line (r -a, Fig. 2; Fig. a, is a detached perspective view of the two parts of the coupling used for attaching the hood to a conduit.

In the above drawings 1 represents a pipe or other tubular conduit for electric conductors and 2 is the outlet hood invented by me. This latter consists of a tubular casing in the shape of a bend, the line of whose outlet lies at about an angle of 45 to the line of its inlet. In the present instance said outlet is laterally flared or extended so that it has an elongated rectangular form and it is closed or covered by a plate 3 of insulating material held to it by screws 4; being provided with a number of outlet openings 5 for wires or cables. As is obvious, after the cable carrying conduit 1 has been mounted immediately adjacent a wall, as shown in Fig. 1, it usually cannot be moved out sufliciently to permit of the outlet hood being bodily screwed upon its end and on this account I so form the inlet end of the hood 2 that it is in effect bell mouthed for the re ception of the end of said conduit 1. It is so proportioned that the inner surface of said conduit is flush with its inner surface and for the purpose of permanently coupling it with the conduit I provide it with a coupling nut 6. This latter is in the form of a collar having an internal annular recess for the reception of the flanged or hell mouthed end 7 of the hood 2 and is interiorly threaded to receive the correspondingly threaded end of the conduit 1. In order that this nut may be movably mounted upon the bell mouth end of the hood, I cast it in a single piece having two parts 6 and 6*, connected by relatively thin webs S which are. afterwards broken to permit of the separation of said parts. These latter may then be mounted upon the bell mouth end of the hood 2 and by means of the rough or serrated surfaces formed by the edges of the broken webs 8, said parts may be accurately matched together so that the collar has its original form and dimensions. The parts are then connected by rivets 9 or other suitable holding means, so that while being free to turn on the bell mouthed end of the hood 2, they are none the less permanently fixed thereto.

WVhen it is desired to mount one of these hoods on a conduit 1, it is merely necessary that the nut 6 be screwed upon the threaded end of said conduit until the end of this latter seats within the bell mouthed end of said hood as shown in Fig. 2. The wires or cables, which have previously been run through the conduit and the outlet end of the hood, are then run through the appropriate openings 5 of the insulating plate 3, which may thereafter be secured in position. As is obvious, this mounting of the hood upon the end of the conduit may be accomplished Without bending or requiring said conduit to be moved out from the wall more than the slight amount required by the thickness of the nut 6 and after being placed in position is of such a construction and arrangement as to prevent all entrance of moisture to the conduit.

The construction of both the hood and its collar is relatively inexpensive and is of such a nature as to permit of their mounting on the end of the conduit witha minimum expenditure of time and labor.

I claim 1: An outlet hood for a conduit consisting of a tubularbend having a bell-mouthed end formed to receive a conduit; With a coupling nut inclosing said bell-mouthed end and freely rotatable thereon, said nut being flanged over the bell mouthed end to prevent relative longitudinal movement of the bend and nut and being threaded for the reception of a threaded end of the conduit.

, 2. An outlet hood for a conduit, said hood consisting of a tubular bend having a bell mouth end formed to receive a conduit, and

' a two-part coupling nut and means for connecting the parts of the nut, said nut having an annular recess adapted to receive and embrace the bell mouth end of the bend and 'permitting the rotation of the nut While preventing relative longitudinal movement of the bend and nut, said nut being internally threaded from said recess to one end so as to be capable of being secured upon a threaded end of a conduit.

In testimony whereof, I have signedmy name to this specification, in the presence of two subscribing Witnesses. V
