Application filed i'ipril 9, 1909. Serial l te. icence To all whom it may concern:

lo it known that I, FRANK PARSOSS, a citizen ot' the United States. and a resident of Boston. in the county of Suffolk and State of Massachusetts, have invented a new and metal improvement in Cord 'lerininali-i, of which the following is a specification.

My invention relates to 'cord-terminals and its object is to provide a connecting clip that may be cheaply manufactured and by means of which a conductor may be secnrely retained in connection with a-cot'iperatingg contact or plug, especially where the apparatus employed is subject to shock and jar-as in the case of a utomobilo or moton boat spark-plugs.

in carrying out my invention I prefer to.

employ two flat conductingmembers of spring material appropriately formed to provide a housing for the head of the plug with which the device is to be nsed and means so uniting said members that the terminal may be snapped over said plug and elastically secured thereto, thereby dispensing with locking devices or other movable members sometimes employed with cordterminals.

The drawings which accompany and form a part of this specification show one embodiment of my invention whereby the foregoing object has been realized in practice.

In the drawings Figure 1 is a side view of my improved cord-terminal and its cooperating spark-plug. Fig. 2 is a central section of the cord-terminal shown in Fig. 1, and Figs. 8 and 4.- are top and bottom views thereof respectively.

In the drawings selected for more fully disclosing my invention, 1 represents a that piece formed substantially shown of any suitable material such as spring-hrass and provided near its front extremity with a depression or cupped portion ishown in the present instance as circular and adapted to rec we the head 11 of the spark-plug 13.

This cupped portion may be perforated as shown at 5 for the purpose of adapting the terminal to types of plugs other than that shown herein.

2 represents a member cooperating with the memher l and also constructed of elastic material such as spring-brass. The member 2 is provided with a slot 2 of substantially the shape of the r portion 8 of the memher 2. so that the latt :,7 be stamped from undnc waste of material. The forward e1 cf the. members 1 and 2 are reversely beveled as shown so that the terminal may easily be snapped oveit'the plug with which it is intended to he used. I

The iliQlill-;"" are together as by the til 1 5 and are arranged so that the slot and cupped portion. cooperate to form a housing tor the head of the plug shown in the pr nt instance at 11.. The member is provided with :1 hole 7 throng 1 which. the conductor 9 may he passed and then bent over upon the member 2 and secured thereto in any suitable manner. In the present instance I have illustrated one way in which the connector may he secured a .e terminal. in this particular instance ion. of the insulation. of the conductor as shown at M thereby exh of the conductor, the tl'ii'ough the hole 7 and an. secured to the memi;- cord or insulating e of this particular erminal to the connection only of the terminal is execs ii iii the jarring of the motor vch h the device is employed cannot cause any portion of the terminal to come in contact with metallic parts of the engine and thereby cause shortcircuiting as in the case of several-types of cord-terminals now in common use.

In Fig. 2, 15 represents the can of a well known form of sparloplng and this cap terminates in head 11 provided with a neck 12. in attaching the cord-terminal to a plug of this type the terminal is placed so that the head 11 will enter the recess between th'e beveled edges 6 and the neck 12 will. ente the slot 2. when so positiened, the corcl-terminal may he forcet torward over the head, the members 1 and 2 having sutlicient elasticity to permit terminal to be snapped over the head and secured 'striobrass withont and doctors is tl thereto by their elasticity.

It will be obvious that a very firm, al-

though readily removable, connection mey-c he formed by my cord-terminal end after the'latter has been snepgied over a plug and the plnghead secured in the tie pression or cupped yortion it will impossible to remove the terminal from t x. plug withotit first pressing downward upon the rear 'igortion of the terminal so as to slightly lower ant thereby slightly elevate the fmni part ml the cupped yortion over the heed, whereupon the terminal may be Withdrawn from the ping. Whenever by Wear 01' otherwise the members becdme ieesmietl or the parts altered, the rivet connection of the members may be readilytightened.

it claim:

A cord-terminal comprising a flat body of spring material provided With an unslotietl cupped-ea a flat body 2 of spring material provideti with :1 slot 2 underlying said cap, said slothaving substantially the shape of the rear portion 8 of said body 2 e the n'ieinber 1 from the and the front edges of eacn 'eisnfli 000193 being reversely beveledtoprovide an 'ien i trance for the plug withAvhich the fiepjninal" is to be-used, and means near th end of the terminal securing said-bodies to gether so that the cap and slotted body form a housing Which-maybe snapped over i the'head of alug" and secured thereto by the elasticity 0 said bodies.

In testimony whereof, I have hereunto subscribed my name this 6th day 'of April 1909;
