Haven, Conn., a corporation of Connecticut Application November 1, 1935, Serial No. 47,808
1 Claim. (Cl. 247-18) This invention relates to improvements in water-tight connecters for electric-connection boxes.
One object of this invention is to provide an improved water-tight connecter for electric-connection boxes which will effectively prevent the entrance of water past the cable and into the box. Another object of this invention is to provide an improved water-tight connecter formed of simple elements readily manufactured and readily assembled to produce a durable eflicient construction at minimum cost.
With the above and other objects in View, this invention includes all improvements over the prior art which are disclosed in this application.
In the accompanying drawing, in which certain ways of carrying out the invention are shown for illustrative purposes:
Fig. 1 is aifront elevation illustrating a watertight connecter made in accordance with this invention applied on a portion of a connectionbox;
Fig. 2 is a right-side elevation of Fig. 1;
Fig. 3 is a rear elevation of Fig. l, with the connection-box omitted;
Fig. 4 is an enlarged sectional View on line 4-4 of Fig. 1;
Fig. 5 is a perspective view of the clampinghood;
Fig. 6 is a perspective view of the compressionmember;
Fig. '7 is a perspective view of one form of sealing-member; and
Fig. 8 is a perspective view of another form of sealing-member.
In the description and claim, the various partsare identified by specific names for convenience, but they are intended to be as generic in their application as the prior art will permit.
40 Referring to the drawing, I0 is a plate or part of an electric-connection box which is provided with an internally-threaded cable-hole ll therethrough. I2 is a compression-member or bushing having a cable-hole l2 therethrough and an ex- 45 ternally-threaded portion l3 adapted to threadedly engage in the threaded opening I I. The cornpression-member l2at its opposite end has a continuous end-flange or compression-flange H and a pair of ears li each having a threaded hole 50 therethrough. A clamping-hood I6 is preferably made hollow or concave, as shown, and has fitting therein a sealing-member I! of readily deformable material, preferably elastic material such as Soft rubber or the like. Clamping-hood I. has a cable-hole I! therethrough.
Screws or bolts it extend through cars it formed on the clamping-hood l6 and threadedly engage in the threaded ears it of the compres= sion-member it. By adjusting the screws l8 to the desired degree, the sealing-member i7 is 5 crowded or compressed and caused to seal water tight, the area between the sealing-member Ill and the surface of the cable 2t, and the area between the sealing-member ill and the compression-fiange it of the compression-member I12, it thus preventing the entrance of water to the interior of the compression-member i2.
The threaded joint ll, 83 can readily be made water-tight in any suitable well-known way, as by means of white lead or equivalent material. it Thus, all possible paths for the entrance of water past the wall it and to the interior of the box are rendered water-tight against the entrance of such water. It will beappreciated that the compresslop-member it? may be connected in water-tight fashion in any other suitable manner to the wall it.
The sealing-member ll has an elliptical cable= hole 2i therethrough to conform to elliptically= shaped cables when they are used. But Where 5 a round cable is used, a slightly-difierent sealing-member 22 is employed, in which a cable-hole 23 of round form is provided to make proper sealing contact with a round cable extending there-= through. Either of these sealing-members ll or 0 22 may be used in the same connecter, as the outside contour of both sealing-members is the same and fits in the cavity of the clamping= hood it.
The invention may be carried out in other spe- 35 cific ways than those herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are therefore to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claim are intended to be embraced therein.
Iclaim:
A water-tight connecter for electric-connection 5 boxes comprising: a hollow clamping-hood having a cable-hole therethrough, a flange at one end, a pair of ears spaced back from the front edge of said flange, and slots in and extending through the front edge of said flange in front of said ears; a sealing-memberofreadily-deformable material and having a cable-hole therethrough and adapted to fit in said clamping-hood; a compression-member having a cable-hole therethrough, a compression-flange adapted to at 56 pair of ears adapted to fit within said slots. said compression-member being adapted to be connected to a plate of a box provided with a cablehole through the plate and with said sealingmember between said clamping-hood and said compression-member and with said cable-holes of the clamping-hood, sealing-member, compression-member and plate in general alignment; and
adjustable -clamping-bolts threadedly connectin: the ears of said clamping-hood and compres- ,within the flange of said clamping-hood. and a
