To all whom it may concern:

Be it known that I, 'nnnnnn H. VIBBER, 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 Im roveinent in Conduit- Caps for Electric nstallation; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to he a full. clear, and exact description of the same. and which said drawings constitute part of this specification, and represent, m

Fig. 3 a side view showing the ca 1 as applied to a vertical inside conduit placed against the wall. Fig. 4 shows the cap as used for inside or outside work with the elbow-piece removed and replaced by a lock-nut and bushing. Fig. 5 a view in vertical section of I" i 4.

Fig. 11 a reverse plan view thereof.

My invention relates to an improved conduit cap for use in electric installation. the object being to produce at a low cost for manufacture. a simple. compact. cliectivc and convenient cap in which the number of nuts is reduced to the minimum, and which is by preference constructed for conversion for use upon either vertical or horizontal conduits or pipes.

With these ends in view my invention consists in a conduit-cap having certain dctails of construction and comhinatimis of parts as will he hcwinaftcr described and pointed out in the claims.

In carrying out. my invention as herein shown. I employ an elhow-piccc comprising a sleeve 3 provided with a set-screw 3 by which it is adapted to be secured to a verlicul conduit or iipe 'l or a horizontal conduit or pipe f |rcfcrrcd the cllmw-piece l tal conduit or pipe,

may be adapted to be secured in place by its provision with internal screw-threinls or in some other way, not requiring description as forming no part of my invention. The said elbow-piece also comprises a sectorshaped portion (3 merging at one end into the said sleeve 2 and provided at its opposite end with a bearing-flange T sl ig. 9). which, as shown, stands at an an e of 45 to the longitudinal axis of the s eeve. Of course the inclination of the hearing-flange 7 to the axis of the sleeve may be varied from 45, if desired for any lt'llBull. The said flange 7 encircles an annular wire carrying flange S (Fig. 9) extending at a right angle to it and by preference employed for carryin as it were, the wires as the same emerge om the elbow-piece. The hearingflange 7 aforesaid, is provided, as shown, with two 0 positely extending perforated ears 10 for the reception of screws 11 which pass t-hrou h inwardly opening radial slots 12 formed in the inwardly turned bearingflange 13 of a hub 14 located in the center of a U-shaped plate 15 formin as may be said. the frame of the device. he said plate 15 being provided at its square lower end with arallel arms 16. 16, supporting an insulatmg block 17 containing holes 18 for the passage of the wires. If preferred the dock 17 may be re laced by a plate containin bushings made from non-conducting material. The said U -shaped frame IS adapted in size and form to have the flange 19 of the hood 20 hooked over it, the inner portion of the said hood having a U-shaped openin receiving the said hub 14 and p ate 15, an the bottom of the hood having a large rectangular opening 21 receiving the arms 16, 16, and block 17 aforesaid. whereby the lower end of the hood is occupied and closed. Screws 22 passing through the hood at opposite mints therein enter threaded cars 22 formed upon the U-shapcd frame 15. The construction dcscrihed,provides.as will readily be undorstrmd. for the rotation. as it were. of the frame 15 upon the elbowpicce of the device, the inwardlv turned rearing-flange ll: of the huh l4 riding upon the hearing lluugc l? of the elbow-piece. When the cap is to he used for capping a vertical conduit or pipe 4, the frame 15 is set upon the clhow-piu-c as shown in Fig. 1. To convert the cup for use upon a horizonsuch as I". the screws ll are removed and the frame is: rotated upon the flange 7 throu h a complete half circie which will bring t e hood 20 into the position shown in Fig. 2 of the drawing: with respect to the horizontal ipe 5. n the last position of the cap wit res eet to the conduit, it may be used for insi e work as shown in Fig. 3. The vertical conduit 4 being placed against the wall, the cap ofisets just enough therefrom for the convenient emergence from it of the wires. It will thus be seen that without the addition of any parts and by simply rotatin" the frame 15, 180 with respect to the e owpiece of the device, I provide for the conversion of the cap for horizontal or vertical work or vice versa.

If desired the frame and the hood may be used without the elbow-piece as shown by Fig. In such use the elbow-niece replaced by a standard bushing 23 and lockout 24, requiring the threading of the conduit or pipe 25. Of course the cap may be used on inside work in an position in w iirh it may be used for outside work, that being purely a matter of expediency, but when the cap is used in outside work it must be set so as to perform its water-shedding function by ri htly )ositioning its hood.

It will fie understood that I prefer to cmploy the elbow-piece in all situations as that reduces the bending of the wires to the minimum; moreover the use of the elbow-piece avoids the threading of the conduit, whereas when the elbow-piece is removed. the conduit must be threaded for the application of the lock-nut and bushing as aforesaid.

I claim 1. In a conduit cap for use in electric installation, the combination with a frame having a hub extending from it in one direction and arms extending from it. in the opposite direction, of a hood having its inner face formed with an opening for receiving the frame and its lower face with an opening for reeeivin the said arms, and means carried by the saic arms for receiving and insulating the wires and closing the said opening in the lower face of the hood.

9. In a conduit cap for use in electric installation. the combination with a frame, of a hood adapted to be removably applied thereto, and an elbow-piece adapted to be fastened to a conduit or pipe and to have. the said frame fastened to it. and having an inclined bearing-face upon which the frame is rotated as required to convert the. cap for use on horizontal or vertical conduits or,

pipes.

23. In a conduit cap for use in electric installation, the combination with a frame, of a hood adapted to he rcmovably applied thereto, and an elbow-piece adapted to be fastened to a conduit or pipe and formed with a sector-shaped portion having an inchned bearing-face upon which the frame is rotated as required to convert the ca p for use on horizontal or vertical conduits or pipes.

4. In a conduit cap for use in electric installation, the combination with a frame, of a hood adapted to be removably applied thereto, and an elbow-piece adapted to be fastened to a conduit or pipe and provided with an inclined bearing-face upon which the frame is rotated as required to convert the cap for use on horizontal or vertical conduits or pipes, and the said elbow-piece being also furnished with a wirc-carryin flange located at a right angle to the suit bearing-face and entering the frame.

5. In a conduit cap for use in electric installation, the combination with a frame, of a removable hood therefor, and an elbowpiccc consisting of a sleeve, and a sectorshaped portion having an inclined bearingface and a wire-carrying flange standing at a rightangle thereto and adapted to enter the said frame which is rotated upon the said bearing-face as required to position the hood for use on horizontal or vertical conduits or pipes.

6. In a conduit cap for use in electric installation, the combination with a U-shaped frame, of a. removable hood having a U-shapcrl opening in its rear face to adapt it to be removahl a plied to the said frame. and means carried by the frame for insulating the wires entering the same, the said means closing the lower end of the hood.

7. In a conduit cap for use in electric installation, the combination with a U-shaped frame having a hub extending, in one direction from it and parallel arms extending in the opposite direction; of a removable hood having its inner face formed with a U-shapcd opening for the reception of the frame and its lower face also formed with an opening, means carried by the frame for receiving and insulating the wires. and an elbow-piece adapted to be attached to a conduit or pipe and n'ovidcd with an inclined bearing face to which the hub of the frame is fastened, and upon which the said hub is rotated as rmplircd for positioning the cap for use on horizontal or vertical conduits or pipes.

In testimony whereof, I have signed this specification In the presence of two sulr scribing witnesses.
