' Specification of Letters Patent.

Patented May 15, 1917..

Application filed September 9; 1915. Serial No. 49,764.

To (Mt whom it may concern.

lle it known that I, HENRY T. Pnrs'rn, a citizen of the United States, residing in Phihulelphia, Pennsylvania, have invented certain Improvements in Cut-Outs, ofwhich the following is a specification.

One object of this invention is to simplify and. cheapen the construction of fuse or hunp receptacles or sockets such for example as'are commonly used in cut-outs, the design and arrangement of parts being such that less material is required than has heretofore been considered necessary and at the same time better electrical contact between certain of the parts is insured.

These objects and other advantageous ends I secure as hereinafter set forth, reference being had to the accompanying drawings, in which,

Figure 1 is a perspective view of a cutout in which. the fuse receptacle is made'according to my invention;

Fig. 2 is a vertical section taken through i one of the fuse receptacles and the terminals two substantially cylindrical chambers 2 and 3 for the reception, of two fuse receptacles, and provided with two transversely extending channels 4; and 5 for the reception of a pair of line wires. Each of the receptacles includes a substantially cylindrical threaded metal shell concentrically mounted within one of the cylindrical chambers of the base 1 and made in the form of a cup from whose bottom is cut a transverse tongue '5 which is bent through an angle of 180 so that it projects in a plane slightly above that of the bottom to one side of said shell. Said tongue is designed to extend through the vertical opening in the side of its chamher in the porcelain base andlies within a recess formed adjacent thereto. Within the metal shell. 6 is mounted a metal plate 8 including a portion having a slot 9 of the same width as the slot from which the tongue 7 was cut and made of generallycin cular outline so that it will fit within the bottom of said shell. 6. From said body portion a projection 10 extends for a distance substantially equal to the length of the tongue 7 and it is noted that this member Sis made of metal considerably thicker than that of the shell (5, having two oppositely placed lugs 11 at the end of the extension 10 and formed with a threaded hole 12co'ncen trio with said end.

It is noted that while the two arms or branches 13 of this member 8 rest upon the side portions of the bottom 14 of the shell 6, the extension 10 projects under and in engagement with the tongue 7,which adjacent its outer end has a hole 15, through which passes a'screw 16 threaded into the opening 12 of the member 8 so as to form a'means for the attachmentof a branch conductor.

The metal shell 6 is held in place by a fiber washer 17 placed in its bottom in engagement with the branches 13 and engaged by a washer 18 through which a screw 19 passes centrally, into an opening in the center of the bottom of the chamber in which said shell is mounted. Said screwis threaded into an opening in the end of a connecting strip 20 which extends in a cavity formed in the under side of the porcelain base 1, into one of the channels 4 or 5 (in the case illus' trated the channel 5) where it terminates ina fiat portion '21. This latter has a 006perating conduct 1r-clamping plate 22 held to it by a screw 23 and both it and said plate are transversely grooved or bent out to form a channel for the reception of the properly barcd conductor which is to be connected to the strip 20.

Similarly the second shell 6 of the cut out is hold in place by the same means as those heretofore described in connection with the shell 6, excepting that its conduct ing strip 20 shown in dotted lines in Fig. 2, is of such a length that its outer end extends into the channel 4 where it is provided 7.

of the member 8 and by the sides of the slot in the bottom 14 of the shell 6, but without contacting with the metal thereof.

WVith the above described arrangement it \vill be' noted that the piece cut out from the bottom, of the shell 6 is utilizedto insure good electrical connection With a branch conductor engaged by the screw 16, since said conductor is necessarily confined between said screw (Whose head itself constitutes a washer), and the tongue 7, so that said conductor is made to electrically engage the metal of the shell itself. At the same time the shell is more firmly than heretofore held in place, since the screw 16 passing through the hole 15 into the hole 12, insures that the various parts are retained in their proper positions.

I claim 1. The combination of a metal shell having a tongue out from its bottom and bent through an angle of substantially 180; a metal piece extending into the lower part of said shell and projecting under said tongue; a contact in the shell but insulated from the same; and means for connecting a conductor to said contact.

2. The combination of a metal shell hav- .to one side of said shell; a forked metal plate having its branches in engagement with the bottom of the shell on either side of the slot and having its body projecting in contact with the tongue; a binding screw passing through the tongue and threaded into said plate; with a central contact for said shell.

4. The combination of a metal shell having a tongue cut from its bottom and bent at an angle to the plane thereof; a metal piece in engagement with a portion of the bottom of the shell and in contact with said tongue; means for connecting a conductor to said tongue and to said piece; and a central con tact for the shell.
