Patented Oct. 1, 1929 UNITED STATES PATENT OFFICE PAUL M. HENGSTENBER G, OF WILKINSBURG, PENNSYLVANIA, ASSIGNOR TO WEST- INGHOUSE ELECTRIC & MANUFACTURING COMPANY, A CORPORATION OF PENN- SYLVANIA TERMINAL ron ELECTRIC oonnuorons Application filed July 14,

My invention relates to terminals for electric conductors and particularly to means for securing terminal clips to their bases.

Heretofore, terminal clips have been secured to their basesby means of square-- shaped rivets, in order to maintain the terminal clips in rigid positions with respect to the base upon which they are mounted.

Inasmuch as such rivets are usually made of' rather soft or pliable metal, ,the clips have a tendency to work loose or to rotate about The object of my invention is to provide for mounting a clip upon a base with the use of the well-known round-shaped rivet in such a mannerthat the clip will be held firmly and will have little tendency to work loose or rotate.

It is also an' object of my invention to proin operation and capable ofbeing readily and economically manufactured.

Another object of my invention is to facilitate the fastening of the clip upon its base or support. Y

Other. objects of the inventionwill, in part,

' be obvious and will, in part, appear herein after.

The, invention, accordingly, is disclosed in the embodiment thereof shown in the-accompanying drawing and comprises the structural features and the combination of elements and arrangement of parts which will be. exemplified in-the construction herein-' after set forth, and the scope of the application of which will be indicated in the claims.

For a fuller, understanding of the invention, reference may be had to the following detailed description, taken in connection with the accompanying drawing, in which: Figureil is a top plan view of a plurality of terminal clips mounted upon a base, in

accordance with my invention;

Fig. 2 is. a view, in section, taken on the I line II- -II of Fig. 1;

Fig. 3 is a view, in perspective, of a portion of a base prepared to receive a clip..

- Fig. 4 is a view, in perspective, of one of the clips illustrated in Fig. 1; and

1927. Serial no. 265,547.

.Fig. 5 is a vertical, sectional view of a rivet for uniting theclip to its base.

In the drawings, I have illustrated the terminal structure'as comprising a base 1 and a terminal clip 2 that'is mounted upon the base by'means of a rivet 3.

-The base 1 may be constructed of any suitable insulating material, such as fiber board, or the like, and is provided with a D-shaped aperture 4 for receiving the rivet 3 and a portion of the clip, as will be more fully described hereinafter.

As shown, the clip 2 is an elongated plate of suitable length and width and is preferably stamped from sheet metal. It has ainsulating'base 2 after the clipis mounted thereon. a

n It will be noted that the clip is secured to the base by means of a single round rivet. In

'order to prevent the clip from working loose or rotating on the rivet, the rivet aperture 8 therein is formed by displacing a portion, of

the clip and thereby forming a tongue or lug '9 that will be disposed in the aperture 4 in the base when the clip is mounted upon l and riveted to the-base. The aperture in the base is'larger than the aperture in the clip and is shaped somewhat like a D in order that the lug 9 may be disposed therein, with one side against it'siflat wall 10while the rivet is secured in the rounded portion of the aperture. While the D-shaped aperture has proved to besatisfactory in holding the rivet and lug and thereby preventing the clip from rotating, it will'be understood that an aperture of any other shape may be employedside relation.

In assembling the terminal, the terminal clip 2 is seated upon the base 1 with itslug 9 disposed against the flat 'wall 10 in the which will receive the rivet and lug in side-by- D-shaped aperture 4 and with its aperture 8 in alinement with the unfilled portion of the -aperture4. While the clip is in this position,

the round rivet 3 is pushed through the aperture 8 in the clip into the rounded part of the aperture 4 in the base and its ends are turned over to securely fasten it in such POSltlOIlr \Vith the lug 9 of the clip 2 located beside the, rivet 3 in the base, the clip will be held firmly and will be prevented from working loose or rotating upon the rivet.

While the illustrated example constitutes a particular embodiment of my invention, I do not limit myself strictly to the'details shown, since, manifestly, the same may be varied considerably without departing from the spirit of the invention, as defined in the pris'ing a base provided with a D-shaped aperture, a terminal clip having a flat central body portion disposed to form a D-shaped aperture and a lug depending laterally from the flat side of said aperture, and a rivet distongue engaging the flat side of the D-shaped aperture in the base, thereby causing the curved sides of the D- haped apertures to coincide, and a rivet extending through the apertures, said rivet being disposed to enapertures to maintain the sides of the apertures in alignment and to retain the tongue in engagement with the flat side of the base aperture, 'thereby to prevent the terminal member from being rotated on the base.

V In testimony yvhereof I have hereunto subscribed my name this 7th day of July PAUL M. HENGSTENBEltG.

posed to extend through .the apertures to secure the clip to the base, said lug on said clip being: disposed beside the rivet in the opening and adjacent to the flat side of the base apertiire for preventing relative movement of the clip and the base.
