.which is durable-'and compact, which provides a convenient means for mounting the apparatus so that it will be well protected and readily accessible and a structure which is well adapted to andpservice conditions to which apparatus of this type is subjected.

One feature 'of thisvinvention comprises' the arrangement of a mounting` plate for jack springs, fuses and protectors, whereby 'these various devices are supported in a convenient manner well insulated from all adjacent parts and thejack springs are retained in a fixed relation to the sleeve of the jack.

1. Fin. 4 is Other features of this invention relate toA the various details of the apparatus, supports andcover and other details of'construction.l

In the drawings-Figure 1 is a perspective of the device with the cover removed illustrating one side of the mounting plate and' supported parts.- Fig. 2 is a view with the cover in section illustrating theopposite side of the mount-ing plate from that illustrated in Fig. 1. Fig. 3 is a horizontal sectional view taken upon line 3-*3 of Fig. al horizontal sectional view taken upon line 4-4 of Fig. 2. Fig. 5 is a sectional view taken upon line 5-5 of Fig. 2.

In the drawings, 5 designates a .circular base carried by a bracket member 6 which is adapted to be secured to a pole or other support; As shown the base 5 and bracket 6 are formed integrally, preferably by casting, and the bracket is provided with aper- Specication of Letters atent.

A sleeve 9 formed integrally with the lbase 5 adjacent to said opening extends downwardly from the bottom face of saidl base and serves' as a guide for thev plugr when it is to beinserted.

Mounted upon the base 5 is a verticall larranged plate10.l This plate 10'is pre pliig maybe inserted' erably formed integrally with said base and is strengthened by I means of laterally projecting reinforcing ribs 11 thereon: Later.-

`ally arranged rect-angular .openings 12 and 13 are provided near the opposite ends of said plate. Mounted upon the plate 10 between `said rectangular openings 12 and 13 are jack and contact springs 15, 16, 17 and 18 insulated from each other and fromV said plate. The inner ends of the jack springs 15 and 16 are arranged directly in line with the opening 8 and have their ends oiset in a vertical direction to make contact with ring and tip contacts on a plug. Each yot the springs is bent back upon itself at its .upper end to form a sleeve 20 which is tapped to receive a binding` screw 21v for securing conductors to said s prings.l.As shown in Fig. 3these springs 15, 16, 17 and 1 8 are mounted upon a bracket 22 which is rigidly secured to the mounting said springs being insulated bracket 22.. Mounted upon one plate 10 is'a .block plate 10;

Mounted upon one side of said porcelain block 25 are carbon protectors or lightning arresters 27, 27 of a type well known in the -art and each of which comprises two carbon blocks 28 and 29 supporting` between them a strip of mica 30 and all being held together by one end .of a spring contact 31,

The `plate 'l0 is approximately thelsame width as the diameterA of the basey except at its klower end where it is cut away to form notches 50, 50 adapted to interlock. witha cover 5l with which the apparatus vhereinbet'ore described is protected. As shown inv Figs. 2 and 5 the cover 5l is cylindrical in shape and of adiameter lto fit snugly over the above apparatus'and base plate. Located near the lower end of said cover is an interior flange 52 adapted'to vrest upon the upper face vot' said base 5 when said cover` is in place.; As shown, this' ilange is provided .lwithfoppositely located notches 53, 53 adapted as the'cover is placed over the parts or removed to engage the lmargins of the turned through alslight angle'the' fla-nge 52 is brought into locking engagement with the lower end of the plate l0 by reason of the notches 50, 50. A' projecting lugk on the cover is adapted` to be brought into engagement with a corresponding lugf on t-he bracket 6; the two lugs being provided with alined openings adapted to receive a padlock. l
