Specification of Letters Patent. Application filed septen her 1,1904.- Serial No, 222.932.

Be it known that 1, CHARLES SvEivsoN,

a citizen of the United" States, residing at New Britain, in the county of Hartford, State of Connecticut; have invented certain new i and useful Improvements in Electrical Connections, of which the following is a full, clear, and exact description. My invention'relates to improvements in electrical connections which are particularly useful for spark-plugs for internal combus tion engines and the like, although, of course,

. the invention is not confined to this use.

The main object is to provide a simple and effective connection, the constructionof the same bein such asto enable the user to adjust the ca 1e at any desired an le relatively to the part to which it" is attac ed Without im airing the efiiciency of said connection.

1 conventionally represents a portion of a spark-plug. ,1

2 represents one of the electric'terminals;

Secured to this terminal in any convenient mannerfor example ,by means of a nut 3- a metallic spring-clip-furnishing side arms 4 4, which are so arranged as to yieldingly press toward each other and so as-to grip with suflicient 'force any member that may be placed between them. In a suitable-yielderforatio'ns are ormed to receive and secure y holdand support a ball-like head 5 of a terminal mem her arran ed to be secured to anelectric'cable 6 in any esired'manner. The sides 44 preferably conv rge at-an intermediate point to 1 form a contracted throat or passage. The

perforations'are oppositely arr ed in the contracted ortion ofthe cli an the edges of these e orations eacha 0rd a secure seat forthe all-like head 5. These seats are 1 preferably circular inoutline andb bearing against opposite sides of the ball-1i e head 5 hold thesame against longitudinal or lateral displacement, but ermit rotary and oscillating movement wit out interfering with the electrical connection.

As indicated in Figs. 1 and 2 by dotted lines, the head 5 may turn so that-the cable may lead to the retaining-cli in a direct line or at any anglethereto'. T erelatively ex tensive area of the seats for the head 5 in- I sures a most satisfactory electrical conned.

tion, and, any rolling or oscillating of the head A '5 in said seats in said side arms 4 4 will keep the contacting surfaces bright:

"By the foregoin arrangement the connection is equally e ective irres ective .of the particular angle of the cable re atively to the cli or plug. a

n the drawings I haveshown the preferable construction of the clip, in which the ends of-the side arms are free; but obviously this maybe modifiedlor its angle relatively to the spark-plug may be-varie without departing from the spirit and scope of my invention. p :By the termfperforation I mean, of course, to include as an equivalent having some of the advanta es a deep recess that will afford a seat for t e balllik'e head which will resist longitudinal or lateral movement I thereof, but will permit rotary or oscillating movement.-

What I claim 1s'- An electrical connection device, comprise ing a base, a threadedterminal carried there'- by, aclip, a nut operable on said terminal for.

ing yieldin side armsthe ends of which approach eac other and are provided with resecuring said clip to said base, said clip hav-,

cesses, and a flexible conducting-wire mem-' her having a spherical tip adapted to be seat -ed insaid recesses.
