To (all whom it may concern:

Be it known that I, JOHN ANDERSON, a citizen of the United States, residing at Port. land, in the county of Middlesex and Statev of Connecticut, have invented a new and useful Improvement in Cable-Joint Housings; and I do hereby declare the. in connection with the and the figures thereon, to be a full, scription of the same, ings constitute part of accompanying drawof reference marked clear, and exact deand which said drawthis specification, and

My invention relates to an improved cablejoint housing, the object being to producea simple, compact, and convenient housing which shall exclude-air and moisture from the joined wires of telegraph, telephone, elec and which shall permit ready access to the joint Without destroying or injuring any part of the same.

With these ends in view my invention (301k sists in a cable-joint housing having certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

. As shown in Figs. 1, 2, and 3 of the drawin s, in r improved housing comprises a barrel 2 or ousing proper large enough in diam eter to receive the oined ends of the cables andformed at its right-hand end with inter use with my inn. I

shown, with cog-like spannerrips 5 for engagement by the hook 6 at t 1e end of the spanner 7 of a c0mbination iwrench 8, the

other end of which is formed jaws 9, adapted to engage with waist or central portion of a which is formed at its gronndejoint bevel l with wrenchthe hexagonal coupling 10, flaring inner end with a its outer end the couplin 10 is sli htly en. larged and formed witi externa screwthreads 13, which are taken into by the internal screw-threads 1%, of a coupling-nut 15, formed at its outer end with an annular flange 16, fer enga ement with an annular shoulder-17', formed near the inner end of a Sleeve-like follower 18, extending in line with the said barrel and couplin and havin its inner end cut away to form evels 19 and 20, which coact with the outer bevel 21 and outer feather-edge 22 of awasher 23, set into a recess 24 in the outer end of the couplin 10, the said recess also having bevels 25 an 26 for the reception of the inner bevel 21 and the inner feathenedge 22 vi. the said washer 23. The nut 15 is formed upon its periphery with cog-like spanner-grips 27, which are engaged by the hook 28 of the spanner 29 of a combinationwrench 30, the other end of which is'formed with jaws 31, corresponding to the jaws 9 of the combinationevrench 8, which is the larger wrench of the two. It may now be explained that the con 10, the follower 18, and the washer 23 al respond in inside diameter, Which'is-made just large enough' to receive the pipe 32, which incloses "the bundle of wires (not. shown) forming one end of the cable, which in the drawings is represented by the said pipe 32. sleeve-like fol wer 18 is drawn inward over the pipe 32, whereby the washer 23 is compressed and forced inward into intimate contact with the pipe 32, so as toexclude the ling cor-

1 for coaction with the. said bevel 4 and with external screw-threads I 12, taking into the threads 3 aforesaid. At

possibility of the admission of any air or moisture at this point into the barrel 2, which is also sealed by the ooaction of the hevels 4 and 11, forming the ground joint.

At its left-hand endthe barrel 2 is'formed with external screw-threads 33, which are taken into by the internal screw-threads 34 of a union-nut or coupling-ring 35, the outer end of which is formed with an annular flange 36, which. coacts with an annular shoulder 37, formed near a ground bevel 38 at the flaring inner end of a coupling 39, correspond ing to, but in detail differing somewhat from, the coupling 10, before mentioned, the said ground bevel 38. coacting with a ground bevel 40, formed near the left-hand end of the barrel 2. At its outer end the coupling 39 is formed with external threads 41, which are taken into by the internal threads 42 of a nut 43, corresponding to the nut 15 and formed with an annular flange 44, coacting with an annular shoulder 45 ona sleevelike follower 46, corresponding in construction and operation to the follower 18 and operating in the same way to compress a washer 47, corresponding to the washer 28 already described, upon a pipe 32, which incloses the bundle of wires (not shown) forming the other end of the cable, which in the drawings is represented by the said pipe 32 T he said washers 23 and 47 may be described in' general terms as cross-sectionally wedge-shaped and wider at the inner than at the outer periphery, by pressure upon their inclined sides tends to force them laterally inward at a right angle to the direction of the pressure.

When the housing is in use, air andnioisture are excluded from both ends of the barrel. Should occasion arise for access to any of the wires entering into the joint between the cable'ends, the nut 35 is unscrewed by the wrench 8 and entirely disengaged from the barrel 2, which is then bodily turned by the application of the said Wrench 8 to the spai'iner-grips 5 until its screw-threads 3 are entirely disengaged from the screw-threads 12 of the coupling 10, after which the barrel is bodily drawn from left to right over the coupling 10 and the union-nut 15 and follower 18. In this way all of those portions of the cable ends which are normally inclosed and protected by the barrel are entirely exposed and as free of access as though. no provision were made' for housing them. After the cable ends have been rejoined the barrel is slid over them from right to left until its threads 3 are again engaged with the threads 12 of the coupling 10, after which the barrel is turned into its home position by the wrench 8, whereby the bevcls 4. and 1]. are brought into coaction. Then the nut 30 is screwed upon the barrel to recstablish the joint between the ground bevels 33 and 35.

It will be understood that both of the wrenches 8 and-30 are used at the saine time, one to hold the coupling 10 or 39, as the case may be, while the nut 15 or 4-3, the case may be, is being screwed in either direction. It will also be understood that the jaws 9 of the wrench. 8 and the corresponding jaws 3} where- 1 of the w )IlOh 30 will be applied to the hexagonal waists of the coupling 10 or 39, as the case may be, while the spanner 17 is being usedto turn the nut 35 in either direction 0 the barrel 2 in. either direction.

In the modified construction shown by gigs. 8 to 10, inclusive,the barrel 2 is replaced Y proper and consisting of a body l8, having a cover 49, the body being formed along its sides with ears 50, receiving ins 51, carrying pivotal screw-bolts 52, furnis ed with thumba hexagonal case forming the housing nuts 53, coacting with corresponding'ly-arranged lugs 53, projecting from the sides of the cover 49, the edge of which is ground to rest upon a thin packing 55., placedupon the correspondingly-ground edge of the body 48.. In this construction the detachable couplings 10 and 39 are dispensed with and-their place taken by con lings 56 56, cast integral with the ends of t 1e body 48 andv located within the edge thereof, as shown by Eigi9. In other words, the axial centers of the couplings 56 56 are located at one side of the axial center of the body and cover taken together. The said couplings are adapted for the reception of washers corresponding in construction to those described and threaded for the application of union-nuts 57 and 58, operating sleeve-like followers 59 and 60. The washers are forced into intimate contact with pipes inclosing the wires forming the cable ends, whereby access of air and moisture into the housing it is desired'to reachthe ends of the wires, the cover is removed. 7

It is thus apparent that in carrying out my invention some changes from the construe tion herein shown and described may be made. I would therefore have it understood that I do not limit myself thereto, but holdmyself at liberty to make such departures therefrom as fairly fall within the spirit and scope of my invention.

Having fully described my invention, wnat I claim as new, and desire to secure by Letters Patent, is
