JOHN R.-PATTEE, OF NE'W YORK, N. Y.

ELECTRICAL CGNNECTOR.

Application filed May 21, 1917.

To all whom it may concern:

Be it known that 1, JOHN R. PATTEE, a citizen of the United States, and a resident of the borough of Manhattan, in the city of New York, county and State of New York, have invented certain new and useful improvements in Electrical Connectors, of which the following is a specification.

The invention relates to electrical connectors and particularly to the class known as electric lamp sockets.

One object of the invention is to make a construction which will be simple, easy of manufacture and readily assembled.

Another object of the invention is to construct a connector that can cooperate with and be used with different types oi connecting members. For example, with electric lights having necks or collars of ditierent diameters, or with electric lamps having necks or collars which are provided with screw-threads of difi erent pitch.

As illustrating different forms in which the invention may be employed or realized reference is made to the drawing forming a part of this specification and in which draws.

Figures 1 and 2 are, respectively, end and side views of one form of terminal member that may be employed.

Fig. 3 is a sectional View of a connector with an electric lamp in place of the connector. This is a view similar to one taken along the line 33 of Fig. 1 looking in the direction of the arrows.

Fig. 4: is a sectional view of another form of connector with the lamp'in place therein.

Fig. 5 is an end view of the connector shown in Fig. l, but in Fig. 5 the lamp is not shown.

Fig. 6 is a sectional view of another form of connector; and,

7 is an end view of the connector shown in Fig. 6.

The several connectors shown are in the form of lamp sockets, but it will be noted that the invention is not necessarily limited to a socket construction. The socket or connector shown in Figs. 1 to 3 comprises a terminal or terminal member 1 having a transversely extending main or body portion 2 from which there projects or extends legs 3 each of which legs has at its free end an inwardly transversely extending portion 4:. The legs may be considered to extend lon Patented May 25, 1920.

gitudinally since they necessarily extend in general longitudinal direction from the transversely extending main or body portion 2. The portion a of the legs may be referred to as the lamp engaging portion since the inner ends of said portion are the parts which en age the exterior of the collar or neck A or the lamp B. The legs are pref erably of flexible material so that they may be considered spring legs and it will be observed that the engaging ends thereof are arranged in pairs opposing each other. As the legs are of flexible or springy material they can yield and be employed so as to ac-,

commodate themselves to lamps of different construction; that is, with lamps having difierent exterior diameters on the necks or with lamps having different pitches on the grooved or threaded portions. The socket or connector also comprises a second terminal or terminal member 5 insulated from the terminal 1. The terminal 5 has a shoulder 6 at the inner end thereof and a screwthread 7 upon which there is located at its outer end a nut 8. The terminal 5 extends through an opening 2 in the transversely extending main or body portion 2. This cpening is larger thanthe exterior of the terminal 5 so that the terminal 5 can be insulated from the terminal 1 by the insulating material 9 that is between the inner side of the transversely extending main or body portion 2 and the shoulder 6. Insulating material 10 is also provided between the exterior f the transversely extending main or body portion 2 and the nut 8. The nut 8 provides a clamping means for securing the parts together. Electric wires which supply the current for the lamp are connected one to the terminal member 1 and the other to the terminal member 5. The terminal 5 may be considered to be connected to and to be carried by or to carry the main or body portion 2 of the terminal 1.

In the construction shown in Fig. d the terminal 1 and the terminal 5 are constructed practically the same as the corresponding terminals 1 and 5 above described. The ter minals 1 and 5 are insulated from each other by insulating material 9 and the casing 11 which provides the insulating material 10 it the casing is made of insulating material. (Ether insulating material can also be provided at 1O if, for example, it should be decided not to make the casing of insulating material. In the latter case the casing should be insulated from the terminal 5. In order that the electric current may be conducted to the terminal 1 there is provided a wire 12 which is connected to one of the legs of the terminal l and to a connecting screw 13 to which one of the supply wires may be connected; the other supply wire is connected to the terminal 5 In the construction shown in Figs. 6 and 7 the terminals 1" and 5 are practically the same as the terminals in the construction shown in Figs. 1 to 3 inclusive and hereto tore described. These terminals 1 and 5 are insulated from each other, as by insulating material 9". and 10". A casing le is shown in Figs. 6 and 7 made o'l. conducting material, for instance. sheet metal, and through an opening 15 thereof there extends the terminal 5". This opening 15 is large enough to permit the terminal 5 to be insulated from the casing and insulating material 10 is provided as a part of the in- I sulating medium between the terminal 5" and the casing 14:. To one of the legs of the terminal 1" there is connected an electric wire 16 that is also electrically connected to a connecting screw 17. To this screw 1'? one of the supply wires may be connected and the other supply wire is connected to the terminal 5".

In all of the forms described, it will be noted that the terminals or tern'iinal members are connected together. In each form there is a first terminal member which has a transversely extending main or body portion that is provided with longitudinally extending legs and with which there is associated a second terminal member that extends into a space defined by the trans versely extending main or body portion and the legs.

It will also be noted that the free ends of the legs of the first terminal member have lamp engaging portions which engage, for instance, the exterior contact member or brass collar about the neck end 01": a lamp, while an end of the second terminal member engages the central metallic contact which is at the end portion of the neck of the lamp.

The improvements herein set forth are not limited to the precise construction and arrangement shown and described for they may be embodied in various forms and modifications without departing from the spirit and scope of the invention.

hat I claim and desire to secure by Letters Patent of the United States is:

1. An electric lamp socket comprising in combination a terminal member having a transversely extending main portion from which there project longitudinally extending legs having inwardly extending portions at the free ends thereof adapted to engage lamps having collars or necks of various sizes or collars or necks which are provided with screw-threads of different pitch, and a second terminal member extending through said transversely extending portion.

2. An electric lamp socket comprising in combination a terminal member having a transversely extending main or body portion from which there project or extend in a longitudinal direction lamp-engaging ortions that define the socket portion, said lampengaging portions being bent inwardly he free ends thereof to a position subs antially parallel to said main or body portion, and a longitudinally extending second terminal member which passes through but is spaced from said main or body portion.

3. an electric lamp socket comprising in combination a terminal member having a transversely extending main or. body portion from which there project or extend in a longitudinal direction lamp-engaging portions that define the socket portion, said lamp-engaging portions being bent inwardly and horizontally at the tree ends thereoi to a position substantially parallel to said main or body portion, a second terminal member which passes through but is spaced from said main or body portion, and an insulating member between the outer side of the main or body portion and a clamping nut which is on the outer end of said second terminal. member, said insulating member provides or carries a casing that surrounds the lampengaging portions which define the socket portion.

1. A lamp socket provided with a gripping member having, a transversely extending main portion and longitudinally extending legs bent inwardly to a position sub stantially parallel to said main portion of the gripping member at their free ends to grip the necks of lamps of various sizes.

This specification signed and, witnessed this 19th day of May, A. D. 1917.
