To atZZ whom, it many concern:v

Be it known that I, HUBERT KRANTZ, aciti zen of the United States of America, residing in the borough of Brooklyn, in the county of Kings, State of New York, have invented Improvements in Electrical Outlet-Boxes, of which the following is a specification.

My invention consists of a, modified constrnction of electrical conduit or outlet-box being formed integral with the body of the of the type forming the subject of my Letters Patent No. 680,254, dated August 13, 1901," and in which the connecting-necks for the pipes are each'formed in two parts, one part box and the other a separate .piece.

7 The object of my invention is to somake a box of this patented constructionas tofacilitate and improve the manufacture thereof.

In the accompanying drawings, Figurel is an end or sideview of my improved'electrical outlet-box, showing the separable part of the connecting-neck detached. Fig. 2 is a vertical section at right angles to Fig. 1.- Fig. 3 is a perspective view of the detached'piece', and Figs. 4 and 5 are views of a modification.

A is the body of the outlet-box, and B is the lower half of the split connecting-neck putin place to receive and hold the pipe end.

In Figs. 1, 2, and 3 the plate afand notch a are shownas of wedge-shaped outline, and the bottom edge of the filling-plate hasa semicircular notch in it to form with a like notch in the bottom of the cut-away part a of the side wall the openingO for the passage of the conductors from the pipe when theclamp B and plate a are fitted in place, as indicated by dotted lines in'Fig. 1.

opening 0 is such with relation to the clamp- The size of this (No model.)

ing-pieces B and B as to leave shoulder c, against which the end of the conduit-pipe can bear, and this shoulder is made to flare inwardly, as shown in Fig. 2, to prevent abra-;

sion of the insulating-covering of the conductors at thatpoint. Inthe modification shown 'in- Figs. Land 5 the fiaringopening Ofor'the conductors is shown as formed wholly within the filling-piece a which is carried by the I detachable half of the connecting-neck.

'In'the drawings 1' have shown the'inner faces, of the two halves B B of the connecti ng-neck as provided with projections the bet-;

terto hold the pipe end; but this is not essential, nor is it material what means been ployed for securing orclampingthe two parts the split connecting-neck fas' provided with correspondinglngsbb,throughholesinwhich i I securing-bolts may be passed.
