To all whom it may concern;
Be it known thatI, ERNEST A. LowE, a citizen of the United of North Plainfield, in the county ofSomen set and State ofNew Jersey, (whosepostofiice address is 183 Greenwich street, 'Newi certain new and.
York city,) have invented useful. Im rovements, in Electrical Connectors for El cctric Lamps, of whichv the followingis a specification My inventionrelates to an improved (leev connection betweenan electric lamp or other piece of electrical apparatus anda pair of electrical conductors forming oppos te poles of a circuit and covered withYthe-usual braided.

contact-pins adapted to. penetr'atethe insucontact with the conductor itself upon the application of suitable-pressure, to the point. or. to the conductor.- I v A further object is. toso construct the device that the conductorsmay be held in secure engagement with-the penetrating points by simply twisting the two conductors together.
Theinvention consists substantially of a connector having a pair. of-penetrating-points forming its electrodes or terminals, sald. penetrat'ing-points being properly mounted upon.

'2 shows a socket constructed in accordance with myinvention. Fig. 3 shows a plan of said socket as connected. toa pair of insu-. lated; electric-conductors. Fig. 4 is a side elevation showingthe-application of an in-f .sulating-sleeveto the connector. Fig. 5 is a .partialvertical section through said sleeve, showing the-manner in which it operates to compress the insulated conductor against the penetrating-point. Fig.- ;6 shows a modification'in the .form of. the insulating-sleeve. 'Referring to Fig. 1,- an 1O;is shown having the usual metallic sleeveterminal or shell 1-,.surrounding and mounted- ,upbnthe base of the lamp. Projecting-lateerally from saidsleeve-is the contacting penetra'ting-point 2, which maybe attacheddirectly to. said shell or sleeve-in any desired manner and which isin incandescent lamp.

The latter is alsomounted upon the shell 1, but, insulated therefrom,- as. indi-1 cated, 3 is the central stud or terminal. of the lamp base, to which is attached the elbow-piece 4, carrying the. point 2 andinsue. lated, as shown. 1 The terminal 3 is in electricalconnection, as usual, with one of the leading-in wiresof 1 is electrically connected to the other lead: in -in .wire-.- Each point 2 -2 maybe pro-, vided with the guides 5 whichassist in cen; tering the conductors onthelpoints when ap: plied to the-connector.

of'Fig. 1,,while, 1 in-Fig. 2-indicatfes the metallic shellforming-the opposite terminal of;
thesocket and havingthe-projecting penetrating-point-attached directly to it in the manner already described-. The penetrat .ing-point 2' is .also mounted on the shell and is electrically connected with the terminal 7 of the socket, but is. insulated from the shell;
as shown.v
In Fig. 3 the connector is shown as applied to a pair of insulated conductors. The penetrating-points pierce the insulation of said conductors when the latter are pressed upon the points with sufficient force and make connection with the conductors 6 and 6, thus establishing a circuit through any device which is in proper electrical connection at its terminals, respectively, with the shell on the one hand and with the terminal 3 or 7 on the other. By simply twisting the two conductors 6 6 together after they have been pressed firmly upon the points and as shown in Fig. 3 they will be held securely in position. Hence by my improved construction or disposition of the contact-points I provide a connector which may be safely and efficiently employed without the use of clamping-screws, clam ing-blocks, or other special mechanical app iances for holding the conductors firmly against the points. As will be obvious, the connector is also firmly sustained by its oppositely-projecting points, the strain bein in a direction transverse to the point, so t at the latter does not tend to draw out.
' The connector may be provided, as indicated in Figs. 4 and 5, with an insulating collar or sheath 8, which is adapted to compress the insulated conductors against the points. For this purpose the sleeve may be constructed in any desired manner, but referably is made as a bisected sleeve the ha ves of which may be clamped together by clamp-screws or other devices, (indicated at 9.) The use of such insulating-sleeve is, however, optional. The same may be applied, obviously, to the connector where the same is a art of the lamp-base, as shown in Fig. 1, or w ere it is constructed as a socket, as shown in Fig. 2.
My invention provides a simple and cheap device adapted for use for decorative purposes when incandescent lamps are employed and it is desired to connect the same with insulated electrical conductors temporarily strung for such use. It is, however, also suitable for forming electrical connection between insulated conductors and a translating device of any character under conditions where the use is not a temporary one.
The form of compressing insulatin -sleeve for the connector may be varied and t e pressure thereof toward the laterally-projecting points may be a spring-pressure of the sleeve itself. Thus, for instance, as indicated in Fig. 6, said sleeve might be a metallic springcup 11, provided with an insulating-lining and with slots 12 extending axially from one edge thereof to receive the twisted conductors 6 6 when the sleeve is slip ed over the end of the connector. After t e said connector has been applied to the insulated conductors, as shown in Fig. 3, the spring-pressure of the sleeve is inward toward the slots 12, so that it will compress the conductors upon the points.
What I claim as my invention is 1. An electrical connector comprising a metallic shell upon which is mounted a pair of penetrating contact-points, one projectin laterally outward from the body of the shell and in immediate union therewith, and the other being mounted on but insulated from said shell and projecting outwardly in the opposite direction.
2. An electrical connector for insulated electrical conductors comprising a conducting-shell carrying a pair of penetrating-points projecting outwardly therefrom in opposite directions, one of said points being mounted upon the side of the shell in electrical connection therewith, and the other being insulated from the shell, but in electrical connection with a conductor passing axially through the same.
3. An electrical connector for insulated electrical conductors, consisting of a metallic shell forming the sleeve-terminal of an incandescent electric lamp, and provided with two penetrating contacting-points, projecting laterally outward in opposite directions, one being directly attached to the side of the shell and in electrical union therewith, and the other insulated from the shell, but electrically connected with the opposite terminal of the lamp.
4. In a connector for insulated conductors, a metallic shell forming the sleeve-terminal of an incandescent electric lamp and having a pair of penetrating-points projecting outwardly from it in opposite directions, one being attached to the side of the shell and inelectrical union therewith, and the other being insulated from the shell as and for the purpose described.
5. Ameans for forming electrical connection between a pair of insulated conductors and an electric lam consistin of a metallic shell encircling the ase of the amp and provided with contacting penetrating-points projecting laterally in opposite directions outwardly from opposite sides of said shell, one of said points being insulated therefrom, and connections between said point and one of the terminals of the lamp.
6. A connector for insulated electric conductors, consisting of a metallic shell upon which are mounted two penetratingoints projecting from the sides of the shel outwardly in opposite directions.
7. An incandescent electric lamp having a base provided with a conducting-sleeve connected to one of the leading-in wires and furnished with a penetrating-point attached to the side of the sleeve in electrical union therewith and projecting laterally outward therefrom as and for the pur ose described.
8. An incandescent e ectric lamp having a base provided with a metallic sleeve and a laterally projecting penetrating point directly attached to the outer side wall of said sleeve, and in electrical connection therewith.
9. In an electrical connector for insulated conductors, a pair of penetrating-points proj ecting in opposite directions from a suitable base, combined With an insulating-sleeve 5 adapted to press the conductors against said points.
10. In an electrical connector for insulated electric conductors, the combination with a pair of penetrating-points projecting in oppo- IO site directions from a suitable base, a bisected sleeve for said base and means for clam ing said sleeve upon the base as and for tl ie purpose described.
