ELECTRIC FIXTURE Original Filed Sept. 24, 1925 2 Sheets-Sheet 2 Patented Apr. 29, 1930 1 UNITED STATES PATENT OFFICE HENRY T.- PAISTE, OF PHILADELPHIA, PENNSYLVANIA, ASSIG-NOR, BY MESNE ASSIGN- MENTS, TO THE ARROW-HART & HEGEMAN ELECTRIC COMPANY, OF HARTFORD. CONNECTICUT, A CORPORATION OF CONNECTICUT FIXTURE Application filed September .24, 1925, Serial No. 58,461. Renewed September 14, 1929.

My invention relates to certain improvements in electric fixtures of the type known as candle fixtures, i. e., fixtures that are designed to simulate a candle.

In this type of fixture, there .is a base, and, at the upper end, there is a socket for the lamp. Located within the structure is a skeleton frame that supports the socket.

One object of the invention is to attach the frame to the socket member by a single means such as a screw.

Another object of the invention is to attach all of the parts forming the internal mechanism of the fixture by a single means.

A further object of the invention is to provide means for adjusting the skeleton frame so that it can be used in connection with candle parts of different lengths. I

tails, which will be fully described hereinafter.

This application is a revival of application Serial No. 690,840, filed Februaryfi, 1924.

In the accompanying drawings:

Fig. 1 is a vertical sectional view of an electric candle fixture illustrating my invention;

Fig. 2 is a plan View of the socket;

Fig. 3 is a sectional plan view on the line 3-3, Fig. 1;

Fig. 4 is an inverted sectional View on the line 4-4, Fig. 1;

Fig. 5 is a perspective view showing the parts of the fixture detached;

Fig. 6 is an' inverted perspective view of the non-conducting member, preferably of porcelain; and

,Figs. 7 and 8 are detached perspective views illustrating modifications of the invention. y g

Referring to the drawings, 1 is a bracket having a threaded portion 2 to which isattached the fixture 3. At the upper end of the fixture is a screw shell socket 4 for an electric lamp 5. Surrounding the fixture is an ornamental portion 6 of the fixture and a tubular section 7, which represents a candle. The socket 4 is made of pressed sheet metal having a screw thread of the ordinary type to receive the thread on the electric lamp. The socket is surrounded preferably by a fibre tube 8. In the bottom of the socket is an opening 9, shaped as shown in Fig. 5, and by dotted lines in Fig. 2. Mounted on the bottom of the socket is a terminal plate 10 that has an extension 11 in which is a binding screw 12.

13 designates a fibre washer that is mounted above the plate. 14 designatesa metallic washer. 15 designates a screw, which confines the several. parts and which forms the centre contact in the present instance. Under the socket 4 is a non-conducting block or insulating base 16 of porcelain, or other suitable material having a hole 17 for the passage of the screw 15. The block has a notch 18 at one side to receive the depending portion of the terminal 10. The block 16 is notched at 19 to receive the portion 21 of the terminal disk 20. This disk has a threaded opening 22, which forms a nut for the screw 15. Between the non-conducting block 16 and the disk 20 is a non-conducting fibre disk 23, which is notched as shown at 24, Fig. 5. The terminals 11 and 21 pass through the notches 24.

25, 25 designate two members, which form the skeleton frame or supporting bracket. I

Each of these members, as shown in Figs. 1 and 5, is made in two sections 26 and 27. Each section is perforated, as at 28 and 29, respectively, for the passage of eyelets, rivets, or screws, by which the two parts can be adjustably secured together. On each member of the frame is a longitudinal flange 30. These flanges act as guides when the two parts are adjusted, and tend to hold the parts rigidly when a single eyelet is used in each member.

It will be noticed that the holes in one pair of members are located closer together than the holes in the other pair of members so that minute adjustments are possible. The members 27 of the skeleton frame form an integral part of a ring 31, which has a threaded portion 32 that is adapted to be screwed onto the threaded portion 2 of the bracket 1. The members 25 of the frame are separate. Each member has'an inturned head 33 at its upper end. This head is shaped M101.

as shown in Flg. a .to fit the recesses 34 in the non-conducting block 16. The washer 23 is notched at 35 to receive the bodies of the members 35. The heads'l33 are clamped onto the block 16 by.the' washer 2 3. ,The screw 15, when the parts are assembled, securely clamps the terminal disk 20 onto the disk 23. The single screw fastens all of the parts through which it'pa'sses.

, In some instances, where fixtures of a standard size are manufactured, the skele- 'an eyelet, rivet, or screw. In this instance,

one part is flanged on both sides, and the other part is arranged to fit'thespace between the flanges.

a .By the invention hereinbefore described, it

" {will be seen that the parts can be assembled and secure d in their assembled position by a single means such as a screw, also that the I w skeleton frame can be easily attached to thesocket and can be made extensible to accommodate electric light fixtures of different designs.

I claim: 1. An electric lamp socket comprising a laterally recessed insulating base, a screw shell socket contact arranged at one face of the base, a supporting bracket having attaching means arranged at the opposite face of the base, a wire terminal extending from said screw shell contact into a lateral recess in the base, a second wire terminal insulated from the attaching means of the supporting bracket, and means, related to the center contact, for engaging said-second wire terminal to secure all ofsaid parts to the base.

2. In-aan electric lamp socket, an insulating plate forming a nut; a socket; a terminal plate located in the socket; and a centrally located screw extending through the several parts and into the terminal plate, said screw retaining the socket on the skeleton frame.

4. The combination in an electric fixture, of a skeleton frame made of two members, each member having two sections, the sections of one member sliding on those of the other member; a ring connecting the sections of one lower member; means for attaching the members together; a socket; a non-conductingiblock; a disk, the upper member of the skeleton frame being clamped between the disk and the block; and a single securing member for confining the parts together.

5. The combination in an electric fixture, of a skeleton frame made of two members, each member having a perforated section, the per-' forations of one member being spaced a greater distance apart than those of the other member; means for securing the two members together; and a socket member mounted on the skeleton frame.

6. The combination in an electric fixture,

of a skeleton frame made of two members, each member having twosections, each section having a series of perforations, the sections of one member having perforations spaced a greaterdistance apart than the perforations of the sections of the other member; means for securing the two members together;

. a socket member; and a single securing means for securing the socket member to the skeleton frame.

7. The combination in an electric fixture, of a skeleton frame having inturned heads at one end, a non-conducting block having recesses to receive the heads, a non-conducting disk located under the block and the heads of the frame, a threaded terminal disk, a screw shell socket, and a screw extending through the non-conducting block and disk and adapt,- ed to be threaded in the terminal disk, said screw confining the several parts together.

base laterally recessed to afford spaced channels, a pair of Wire terminals respectively arranged at opposite faces of the base and projecting therefrom into said spaced lateral channels, a screw shell contact arranged at one .end of the base and associated with one ofthe Wire terminals, a center contact at said end of the'base and having an associated element assing'through the base and engaging the ot er 'wire terminal at the opposite face of the base, together with a socket supporting bracket mechanically engaged. by, but insulated from, the terminal engaged by the center contact element.

3. The combination of a skeleton frame having inturned heads; a non-conducting block recessed to receive the heads; a notched disk located under the heads; a terminal
