PAUL F. WILLIAMS, OF CHICAGO, ILLINOIS, ASSIGNOR TO G. & W. ELECTRIC SPECIALTY (30., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

POT-HEAD CONNECTOR.

Specification of Letters Patent.

Patented Mar. 30, 1920.

Application filed March 15, 1910. Serial No. 549,491).

- tors and discloses a different species of the invention described and claimed in my Patent No. 1,154,823, issued September 28, 1915. My invention is designed for use with pothead connectors and provides a construction in which a bowl is used for the entering cable and wherein the cable is separated into its component conductors, which bowl is provided with a removable cover having a plurality of diverging outlets for the individual conductors, which outlets are symmetrically arranged with respect to the axis of the cover.

More particularly my invention contemplates'improved constructional features for establishing the interconnection between the cable conductor and the aerial conductor, which is to be associated therewith inconnection with a removable cover device as set forth.

I will describe my invention more in detail by reference to the accompanying drawing, illustrating the preferred embodiment thereof in which:

Figure 1 is a side view partly in section of my improved pot-head connector,

And Figs. 2 and 3 are details of construction. 1

Referring more particularly to Fig. 1, I show a body portion 1 of the pot-head, which body portion I prefer to call a bowl yvhich is adapted for mounting on any suitable support. The bowl is bent so that its inlet and outlet are angularly displaced ninety degrees. This I find to be of great advantage when cables run horizontally into the pot-head, from whence they are dis: tributed as aerial conductors.

The cable inlet 2 accommodates the cable 3 which has conductors 4, 5, and 22 ,-an adapter 6 being interposed for cables of different size.

The bowl 1 has a removable cover 12,

which through the interposition of a suitable gasket 7, is held in place by adjustable bolts 8. Ears 9 are provided to support the pot-head in place. Outlets 10 are fastened to the cover 12, which outlets are of insulating material, and through which the conductors 4, 5 and 22* are to pass. The conductors 4, 5 and22 are at first soldered or otherwise fastened in place in a double sleeve or socket 11. The insulation of-the conductor is removed for this purpose as shown.

The aerial conductor is also fastened in a sleeve 13, which sleeve has screw threaded engagement with a tubular resilient connecting device 14 secured thereto in addition by a screw 15 passing through a wall 14 in member 14. An insulating cap 16 carries the sleeve 13 and has associated therewith a rotatable adjuster 17 of insulating ciated aerial conductor is to "be placed incontact with the conductor 5, the extension 14 is inserted in the cylindrical member 11 and the element 17 rotated, which on account of its slotted interior surface rotates the lugs 18, ,and thereby the conical element 19 which permits this motion, by virtue of the screw threaded element 11. The lugs 18 entends to push the element 14'very securely into the double sleeve lland securely contact the members 19 and 14 thereby making conductors tight together are necessary when pot-heads for current conductors .Of high carrying capacity are to be used. The element 17 as shown more clearly in Figs. 2 and 3 may be provided withv projections 20, upon the surface so that said projections F may be easily grasped to rotate said element,

, gage for this purpose the slots 24. This 2 or openings 21 may be left as shown more clearly in Fig. 3, which would provide the necessary holding surface.

Countersunk screws 22 are used more thoroughly to hold the outlets 10 in place and prevent them from. turning. A fiber gasket 23 is interposed for cushioning purposes. A nipple 25 is left at the top of the insulator 16, so that insulating tape may readily find lodgment thereon.

It will be seen that as said auxiliary element l7 alone is rotated, when fastening the conductors together, the insulator 16 will not be rotated and the insulating tape, thus, will not be disturbed. Compound 26 is used to fill in the spaces after the parts are in proper position.

While I have herein shown and particularly described the preferred embodiment of my invention, I do not limit myself to the precise construction and arrangement as herein set forth, but having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

A pot head comprising a bowl, a plurality of tubular insulating members projecting upwardly from the top of said bowl, the lower ends of said insulating members being open to the interior of the bowl, rotary insulating members mounted upon the tops of said projecting insulatin members, said rotary members being adapted for rotation relatively to said insulating members, caps mounted upon the rotary insulating members, said caps having their upper ends provided with apertures to receive conductors to be connected, and also to receive insulating material for hermetically sealing said conductors in position, connecting devices within said projecting tubular members and the rotary members and caps mounted thereupon, said connecting devices being adapted to be operated so as to permit or prevent their separation by the relative rotation of said rotary members, and insulating material located within the bowl and extending up also into the tubular members projecting from the top thereof, said insulating material being adapted to hermetically seal conductors located in the bowl and also to extend up into the projecting members to hermetically seal the same, and the portions of the connecting devices located in the upper ends of said projectin members, said relatively rotary members being provided with overhanging portions which serve to protect the upper ends of the projecting members from the elements and also to provide a means whereby said members may be rotated and said caps being provided with downwardly extending portions which overhang the upper ends of the relatively rotary members whereby said members have their upper ends protected against the elements and also whereby the same may be rotated to operate the connecting devices therein.

In witness whereof, I hereunto subscribe my name this 9th day'of March, A. D. 1910.

PAUL F. WILLIAM-S.
