(01. 175—224) 1 2 The presentiinvention relates to electric ‘meter installations and has for an object the provision ‘stallation of several sizes of electric meters by vof a universal installation ?xture adapted to re ceive in substantially tamper-proof condition the various makes of electric meters of the several well-‘known types. the means 'of the invention. Fig. 7 is a fragmentalsectional view showing a modi?ed form of theidevice of the invention. There are numerous makes of electric meters variously used throughout the country by differ Another object of the invention is to provide a ent power companies. There are also several meter installation ?xture with an apertured clo general types of meters commonly known as base sure member adapted to have the clock-work of type or type A meters and socket type or S type any meter project ‘therethrough, and a meter 10 meters, and the meter ?xtures for the several trim member apertured to accommodate a speci?c kinds and types of meters have heretofore ‘been meter and mounted on the closure member, the unsuited to accommodatemore than one make or outermost of the said members sealably secured type ofmeter.

Fig. 6 is a front elevational view of va. ‘gang in- r: and adapted to receive the cover H at the free edges. Cover H has a top ?ange l6 and bottom ?ange 5'1 and is devoid of side ?anges. Cover II has a large aperture [8, circular in shape and adapted to have the cylindrical body of the meter to be mounted to pass therethrough. Removably secured over aperture [8 and the surrounding face of cover H is ‘a meter‘trim 19 in the form of a ring which may be ?at,~concave or convex; de 2,412,558 3 4 pending upon the depth of the trough or the depth fully enclosed meter is properly mounted and ~ ' sealed.

The trims I 9 will in each instance be an on either the righthand or lefthand end of trough annular ring with at least a marginal ?at portion 20 which is of‘greater' diameter than ‘the open II) with either the knock-out 43} or 4| at the top, thus accommodating the ?xture to any desired ing I8 in the removable cover ll.

The member 48 has a double row of holes bore 24 in the adjacent scalable screw 22. In the 49 for the reception of screws such as M and 46 for rigidly connecting a pair of troughs I9 in edge embodiment shown in Figs. 1 to 3, the trim IIl constitutes the ?nal element to be attached in a 20 to edge communicating relation.

The depth of the trough and the depth of the The speci?c mounting of a meter socket or the base of the so-called A type meters on the meter support will vary with different meters, and such meter up to the shoulder will govern the neces sary location of the plane of the aperture in the ~' trim I9. That is to say, under certain conditions of the depth of the trough and a particular me ter, the trim may be entirely ?at or it may be means form no part of the present invention. In practical use, a proposed meter installation is effected by securing one or more of the trough members I!) as required in the desired position. If a plurality of the troughs are to form a con tinuous, interiorly communicating cabinet or In Figs. 2 and 3 a meter support member 29 is 40 trough unit as shown in Fig. 6, members 48 are concave instead of convex, as shown. provided and suitably mounted in spaced relation applied interiorly to overlap the edge butting to the rear wall l3 of trough ID as by forming an integral leg 30 with a foot or ?ange 3| spot-welded to said wall I3. A meter support bracket 32 has a joints of the several troughs in a manner that foot or ?ange 33 secured to the top wall I4 as by spot-welding, while the opposite end is offset to . pass along the rear face of meter support 29, and is suitablysecured as by spot-welding at 313. The ; bracket 32 has a number of tapped holes 35 to selectively receive screw 36 in mounting the me ter base. On opposite sides of the meter support 29 are stirrup-shaped cover supports, 31 which form small ?at seats with tapped holes therein for receiving screws 38 which pass through holes or slots 39 on diametrically disposed sides of the . aperture I8 of cover II and whereby the cover is When trim member I9 is . secured to the seats. mounted in superposed relation on the cover and the mounting screws 22 therefor are secured and sealed, the screws 38 are inaccessible and con cealed. ' I The end walls I2 are provided near opposite > ends with knock-outs ill and M which are pref erably of different sizes. The end wall l2 has a continuous ?ange 42 extending from one face thereof and this ?ange has in its narrow ends a pairof perforations 43 uniformly spaced center~ ward from the longer ?ange portions. The end ' walls l2 are interchangeable and in mounting and securing the same to the top and bottom walls It and I5 of the trough, a screw 34 is passed through . one of said pair of holes 43 into a matching tapped hole 45 in said walls It and I5. The screws M are entered from the inside of the trough, and the structure is thereby made tamper-proof when the will be readily understood from an inspection of Fig. 5. The end walls I2 are provided at the ex treme ends of such trough or troughs, whereupon the available or speci?ed meter or meters, such as 21, 270 and 2100, of one or more makes and/or types are mounted in position and the cover members II ‘are fastened down over the respec tive units. Thereafter the meter trim closure elements I9, HM and I 92 are selected to accom modate the outside diameters of the projecting, encased clock-work mechanisms 2t‘ of each of the said meters, and are set in place to seat over the shoulders 28 of the several meters, whereupon they are fastened in superposed rela tion on the covers by screws 22 which may be suitably sealed, as shown for example in Fig. 4, after the installation is inspected and tested. In the modi?cation shown in Fig. 7 the meter support and meter support bracket of Fig. 2' are omitted and the meter base or socket may be supported by the back wall I32 of the trough or cabinet element IOIJ. A screw 360 threaded into said wall serves to ?x the meter base or socket in place. In this embodiment the cover support ‘element 370, corresponding to element 37 of Fig. 2, is suitably attached to wall I38 as by spot weld ing. I have also arranged to have the meter trim ring I 93 seat on the cover support 316 and the cover III superposed on top of it and sealing screws 380 passing through‘both of these aper tured closure members III and I30 and ‘thread edly engaging in the cover support 310.‘ In this manner two of the screws of the'device of Fig. 2 "2,412,558 5 6 are' omitted, while the .remaining two screws ing' over the open front of the trough element and serve the - double > duty in‘ securing. the: ?nal meter adapted adjacent the periphery of the aperture installation.
