TXTIEATIHIEIR.` CAP Application led November 19, 1928 Serial No; 320,292;

This invention relates to weather caps for electrical lead-in conduits.

The general object of the invention is to provide a weather cap simple in construction, capable of easy assembly, yet affording full protection Jfrom the ingress of moisture or dirt.

Another object is to provide securing means for the cover piece which is permanently carried by one of the major elements of the assembly, does away with the necessity for handling small, loose parts, and avoids the alignment of the screws in threaded apertures at the time of assembling.

Another object is to provide a Weather cap composed ot only two simple castings which are inexpensive to manufacture and which, when assembled with insulator and screws in the manner hereinafter set forth, consists oic only the two separable parts.

With these and other objects in view, the invention consists in the various novel features of construction and combination, all of which will be fully described hereinafter and pointed out in the appended claims.

in the accompanying drawings I have shown an embodiment of my invention, wherein Fig. 1 is an elevation oi' the weather cap assembled on the lead-in conduit; Fig. 2 is a sectional elevation of the weather cap; Fig. is a bottom plan view of the weather cap showing the insulator block with conductor openings; Fig. 4 is a sectional view on line 4 4 of Fig. 2; Fig. 5 is a sectional view on line 5--5 of Fig. 2 and Fig. 6 is a fragmentary section on line 6-6 of Fig. 5.

Describing by reference characters the various parts of the embodiment illustrated in the accompanying drawings, 1 is the usual y upright conduit extending from the elbow 2 which in turn connects with a conduit that eX- tends through the wall or other building part the body member and extends over the .in-

sulator/block 6 which is in turn securely fastened to the body 4. j

The body member 4 is composed of the Vtubular portion 7, `shown as interiorly threaded for the reception of the conduit 1, and having at its upper end. a base 9 that. is surrounded by an upwardly extending ange 10, and from the front of whichv pro]ect iners V11. angel() at opposite sides of thebody memberare lugs 12 which have threaded apertures to receive screws 14. The screws 1.4 after boing passed through the lugs are upset as at 13V toprevent their removal or lossin shipment or handling, but still permitting longitudinal movement suicient to eiect the engagement or disengagement with the cover 5 aswill be hereinafter described.y

Extending inwardly at thetop ofthe tubular portion- 7V is a circular flange 15 which forms a shoulder 16 against whichl the conduit 1 may ,strike when thesmember 4 is secured thereto. The inner periphery of this flange'i maybe rounded as shown to'present a smooth edge-which will not cut or scrapethe conductor insulation as it is drawn'` therethrough. At the junction ofthe lingers 11 with the base portion 9 is a reinforcing flange 9* shown in Fig. Q, which also forms an abutment' again-st whichthe insulator member 6 isheld.

The insulator member 6 iscomposedof any suitable insulating material and is'secured to the fingers 11 by astening'meansl?, such as rivets. The insulator member 6 isrprovid'ed with apertures 18 to receive the conductors 3. Tovaccoinmodate aathird' wire, in case a threephasek circuit is used, the member 6 is provided with; av knocleout opening.' 19 that is vnormally closed by a blank 20. y

The cover member 5' is constructed to'ft about the flange' 10 with a front portionv 21 extending downover the fingers 11 and over the insulator member V(iso-as to substantially coverr the same. Tolimitl the downward movement of the cover over the body4, the cover=member is formed with a lug 22 which engages the upper edge of the iange 10.

At opposite sides of the cover 5, and matchi Extending upwardly from the yaIt ing up with the screws 14 when the cover and body are assembled, are slots 23 to engage down over said screws at the lower edge of the cover and on opposite sides thereof are outwardly extending flanges 24 which are cut by the slots 23 providing shoulders 25 to be engaged by the heads of the screws 14, when the same are screwed in thereby to prevent removal of the cover.

The weather cap as received by the electrician for installation consists as will be observed of only two separable parts; the body member 4 having the insulator 6 already secured thereto and screws irremovably screwed into the lugs 12, and the cover member 5. i

No loose parts are present to slip from the hands of the electrician while assembling the cap on the job, nor is it necessary to align the screws 14 with threaded apertures in securing the cover member 5 in place.

In assembling the cap, the body 4 is secured to the conduit l, the conductors 3 threaded into place and connections made with the conductors from the conduit l. The screws 14 are backed out as tar as necessary to allow the flanges 24 to pass and the cover member placed in position with the screws 14 entering the slots 23. rIhe screws are tightened whereby the screw heads engage the shoulders 25 and securely lock the cover in place.

Having thus described my invention, what I claim is:

1. A weather cap for electrical conduits comprising a body member provided with means for attachment to a conduit, a cover for said body member adapted to lit over the upper edges thereof, locking means for said cover comprising laterally extending headed bolt members on opposite sides of said body adapted for longitudinal movement, said cover being provided with laterally extending langes on opposite sides thereof and slots extending from the edges of said Cover through said flanges providing shoulders adapted to be engaged by the heads of said bolt members when the cover is in place on the body to securely lock the same thereto.

2. A weather cap for electrical conduits comprising a body member through which conductors are adapted to pass, a cover member having its lower edges extending over the upper edges of said body member, flanges on said cover, said cover being provided with slots extending from the edges thereof through said flanges, headed bolt means on said body adapted to be received in the slots when the cover is in place, the heads of said bolt means adapted to engage over the ianges to lock the cover in place.

In testimony whereof, I hereunto attix my signature.

JOI-IN C. BOYTON.
