Specification of Letters Patent.

Divided and this application filed. May 28, 1914. Serial No. 841,502.

To all whom it may concern:

Be it known that we, CARL H. BIssnLL, of Syracuse, in the county of Onondaga and State of New York, and DANIEL C. GIDLEY, of Boston, in the county of Suffolk and State of Massachusetts, have invented a certain new and useful Electrical Appliance, of which the following is a specification.

This invention relates to an electrical appliance, and more particularly to a device, arranged in an electric circuit, for supporting and establishing electrical contact with an incandescent lamp.

The object of the invention is to provide a particularly simple, durable and highly ellicient device of the character stated, and the invention consists of the parts, and the combination and arrangement of parts, to be hereinafter described and particularly pointed out in the claims.

his exemplification of the invention is disclosed in the accompanying drawings wherein Figure 1 is a side elevation, with parts broken away, showing the device associated with a well-known type of Condulet.

F 2 is a plan view of the same.

Fig. 3 is a detail transverse sectional view on the line 3-3, Fig. 2: and

#1 shows detached parts in perspective. E

The appliance comprises, generally, a base of insulating material, preferably porcelain, a terminal sleeve mounted thereon, and pro vided with a slot. a central lamp contact terminal formed of a light strip having sub stantiall v duplicate end portions and a slotted intermediate portion, one end portion resting upon the base and the other being free and spaced therefrom, a terminal memher having a part engaging the end of the sleeve terminal for making electrical contact therewith, and securing it to the base of the appliance, and a second terminal member having a part extending through the slot in the sleeve and through the slot in the lamp contact terminal and engaging with the firstuamed end portion thereof for making electrical contact therewith and for holding it in place on the base member.

' In the accompanying drawings the base member is designated 1 and is shown as of a construction particularly designed for association with a Condulet fitting, but any other desired form of base may be substituted for the one illustrated.

As shown, the base 1 is provided with a flat end surface 2 in the center of which is a post, or boss, 3 having a flat end. The base 1 is further provided with diametrically opposed recesses 4L, 5, opening through the end 2 and with an openin 'fi extending from its under side through the boss 3, and provided with an intermediate shoulder, and with duplicate openings 7 extending from said under side through the end 2 at points on opposite sides of the boss 3.

The terminal sleeve is designated 8 and includes an end wall and a threaded cylindrical side wall. This sleeve is provided with a slot 9 extending through portions of its end and side walls.

The terminal member associated with the sleeve is designated 10 and is shown as a metal. strip having a head 11 with parts extending on opposite sides of the boss 3 and a stem, or shank, located in the recess 5 in the base 1, and provided adjacent its end, remote from the end 11, with a conductor engaging screw 12. Said end remote from the head 11 bears on the bottom or end wall of the recess The head 11 rests against the inner face of the end wall of the sleeve 8 and adjacent its ends is provided with threaded openings 13, registering with open ings in said end wall of the sleeve 8 and with the openings 7 in the base 1, and de signed to engage with the threaded ends of retaining screws 14 which are inserted in the openings 7 from the under side of the base 1 and the heads or which rest against shoulders in said openings 7. These screws act to draw the head 11 into firm electrical and mechanical contact with the end of the sleeve 8 and securely clamp the same against the surface 2 of the base 1.

The central terminal, or lamp contact, is designated 15 and is formed of a light strip of sheet metal bent upon itself intermediate of its length for providing substantially duplicate end portions, one of which rests upon the end of the post, or boss, 3 while the other is free and spaced apart from the first-named end portion and is designed to make contact with the central terminal of the lamp secured in the sleeve 8. The inter mediate portion of the strip is provided with a slot 16 for accommodating a terminal member 17, a part of which is located in the recess at of the base 1, and is provided adjacent its end with a conductor engaging screw 18, and another portion of which extends through the slots 9 and 16 and engages with the first-named end portion of the terminal 15 for making electrical contact therewith and for retaining it in position on the end of the boss 3. The last-named part of the terminal member 17 is provided at its end with a threaded opening registering with the opening 6 in the boss 8 and with an opening in the contiguous end of the terminal 15, and engaging with the threaded end of a screw 19 inserted in the opening 6 from the under face of the base 1. By tightening the screw 19, the head of which rests against a shoulder in the opening 6, the terminal member 17 is drawn into firm electrical and mechanical contactwith the con tiguous end portion of the terminal 15, and securely clamps the same against the end of the boss 3.

The end of the conductor or terminal member 1'? remote from the screw 19 bears on the bottom or end wall of the recess 4: in a manner similar to the terminal or conductor 17. Owing to the fact that the terminal members or conductors 10 and 17 bear on the bottom of the recesses 5 and 4, the terminals or conductors 10 and 17 are braced and held substantially rigid during the tightening of the binding screws 12 and 18.

What we claim is:

1. In an electrical appliance and in combination, a base of insulating material having a bearing face and a boss projecting above the bearing face and recesses in opposite sides of the base, a sleeve terminal having an inturned flange resting on the bearing face, and a slot opening through its cylindrical wall and also the inturned flange, a central terminal located on the free end of the boss and being in the form of a clip bent upon itself and formed with a slot, one side of the clip being'secured to the end of the boss, a conductor extending into one recess, through the slot of the sleeve terminal and through the slot of the clip, and having one end overlying the side of the clip on the end of the boss, a screw extendingthrough the boss, and the overlying portions of the clip and the terminal, and a second terminal located in the other recess of the base and extending through the slot and having portions overlying the inturned flange of the sleeve terminal, the portions of said terminals located in the recesses being provided with binding devices substantially as described.

2. In an electrical appliance and in combination, a base of insulating material having a. bearing face atits end and recesses on opposite sides of the base, a sleeve terminal mounted upon the bearing face, a central terminal mounted upon the base within the sleeve terminal, a conductor located in one recess and connected to the central terminal, and a second conductor located in the other recess and connected to the sleeve terminal, the conductors having binding devices in the recesses and having their ends remote from the terminals to which they are connected, resting on the bottoms of the recesses, substantially as and for the purpose set forth.

In testimony whereof, 1, your petitioner, CARL H. BISSELL, have hereunto signed my name in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, and in the State of New York, this 26th day of May, 191-1, and 1, your petitioner, DANIEL O. Gnmnv, have hereunto signed my name in the presence of two attesting witnesses, at Boston, in the State of Massachusetts, this 28 day of April, 1914:.
