INYEN'I'OR RICHARD G. PHEYSEY, OF ONTARIO, CALIFORNIA.

CONTACT-PLUG FOR ELECTRIC IRONS, HEATING APPLIANCES, AND THE LIKE.

Specification of Letters Patent.

Patented Feb. 2, 1909.

Application filed. August 22, 1907. Serial No. 389,652.

To all whom it may concern:

Be it known that I, RICHARD G. PHEYsEY, a subject of Great Britain, residing at Ontario, county of San Bernardino, and State of California, have invented. a certain new and useful Improvement in Contact-Plugs for Electric Irons, Heating Appliances, and

the Like, of which the following is a specification;

My invention relates to a new and useful improvement in contact plugs for electric irons and the like, and has for its objectto provide an exceedingly sim le and effective construction of spring clip a apted to engage a binding post or to pass over and contact throughout the entire length of the tongue and thus avoid confusing of the members.

A further object of-my invention is to entirely inclose the contact members so as to prevent them making any contact with the damp material which is being ironed and I thus forming short circuits, and a still further object of my invention is to cheapeir the construction of such contact devices by reducing the parts thereof to a minimum, and so design the same that they may be made from sheet material by automatic machinery.

With these and other ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled-in the art to which this invention appcrtains may understand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawing forming a part of this specification, in which Figure is an elevation of a portion of an electric iron showing my improved contact plug attached thereto. Fig. 2, a top View of the plug. Fig. 3, a bottom view thereof. Fig. 4, a side elevation, a portion thereof being broken away to show the recesses therein. Fig. 5, an enlarged view of one of the spring clips in contact with its tongue. Fig. 6, a top view of the spring clip. Fig. 7, an edge view of one of the'spri ng clips adapted to engage a binding post.

In carrying out my invention as here embodied, A represents the plug, which is made of any suitable insulating material preferably porcelain, having molded therein the re= ces's'es B and B, with which the square hole's C and C- connect, said holes being flared at their upper ends as shown in dotted lines'in Fig. 4. Upon one side of this plug at the bottom thereof are formed the slots or channels Band D, which lead into the recesses B and B respectively.

E represents one of the s ring clips, which consists of one or two mem ers stamped and bent from sheet metal and riveted together so as to form springs between the lower or, trons thereof, While the u pe'r portions w ich come n contact with eac 1 other form a hole or socket F, in which is secured one of the contact wires leading from the usual twisted cord. One of these spring clips is secured b means of a screw G in one of the holes C an C, so that the lower portion of these clips will extend into the recesses B and B without touching the walls thereof and in alinement with the slots D and D.

H represents one-of the contact tongues, which is secured in any convenient manner to the terminals H of the heating coils within the iron, here not shown, and the spring cli s are adapted to ass over and embrace t ese tongues or bin ing posts contacting with them throughout nearly their entire length, thus greatly facilitating the passage of the electric current-through these contacts and avoiding the liability( of sparking or fusing at such points.

n practice, a suitable socket on collar I projects'froin the rear ort ion of the iron J and the circuit is ma e v.btetweenJthe line wires and the heating coils Within the iron by simply sliding the plug A through thin socket.

or collar, which wili guid itinto place over the tongues H, causing t e spring members of the clips to embrace said tongues or binding osts, as before described. From this it will be seen allof the contact parts and those which would likewise be liable to divert the direction of the current are entirely by especially ad'apting them for use on round I binding posts. I

It will be obvious that these devices are exceedingly simple and cheap of construction and have very little tendency to wear or become disarranged.

Having thus fully described my invention, what I claim asnew and useful, is-

1. In combination, an insulating plug having recesses and holes formed therein and also slots leading from said recesses, two s ring clips each formed of two members of s iet metal secured together so as to inclose one end of the lead wires, said clips being secured within the holes formed in the plu and extending into the recesses therein, an two tongues or binding posts secured to the terminals of an iron and adapted to project into the plug and between the spring membersof each of the clips, as specified.

2. In a device of the character described, a suitable plug, two clips each formed of two pieces of sheet metal secure d together in such manner as to provide sockets for the reception of the ends of the lead wires and spring RICHARD G. PHEYSEY.
