Application nee January 11, 1912. Serial No. 670,598.

To all whom it may concern Be it known that 1, WILLIAM R. NAYLoR, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Connectors for Neck-Chains, of whichthe following is a specification.

This invention relates to chain connectors, and has for its object to provide a connector for neck chains and the like, comprising a tubular body portion and a click or removable member, the latter having two opposing spring locking arms and a chain engaging eye member all formed of a single piece of spring wire and without the use of solder, by which construction the click may be made of the minimum size and expense and with the maximum holding power.

With these and other objects in View, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

Ofthe accompanying drawings: Figure l'is an elevation of the connector showing the tubular body in section with the click member in position therein. Fig. 2 is a detail of the click member removed, showing the shape when the wire is first bent. Fig. 3 is an enlarged sectional view on line 3--3 of Fig. 2 showing the relative position of the members and the oval shape of the wire in cross section. Fig. 1 shows the click after its inner end has been hammered or swaged tightly together to reduce its size and provide a greater spring tension in the opposite arms. Fig. 5 is an enlarged cross sectional view on line 55 of Fig. 41: showing the general shape of the stock at this point after having undergone the hammerlng or swaging process.

Referring to the drawing 10 deslgnates the tubular body portion which is closed at one end 11, into which end is loosely secured the eye 12 whereby said eye is adapted to readily turn or perform the function of a swivel when connected to the neck chain, not

shown. The opposite end 13 of this tubular member has its edge turned inward as at 14: providing an annular flange for engaging the click in the manner presently described.

It is found in practice that connectors of this character should be made as small and compact as possible and at the same time very strong and durable so that when the chain is connected together by them there is absolutely no danger of its coming apart, and so insure the chain and the valuable pendants which are often worn thereon against loss by an accidental separation of the connector.

In order to provide a simple, practical and effective click that possesses the maximum holding power and yet is capable of being constructed of the smallest size and at the minimum expense, I have constructed the same of a single piece of substantially halfround or oval spring wire as this shape gives the desired finish to the eye or loop, said wire being doubled near its middle upon it-' self providing a middle body portion, then having two parts 15-15, and forming a loop 16 at the bend. Each of these parts is then bent at 17-17 or doubled back nearly upon itselfforming a pair of opposing spring arms 18-18 having outwardly turned manipulating ends19-19 each of said arms being also provided at the bend of said ends witha notch 20 for the purpose of engaging tghei inwardly turned flange 14: on the tubular The connector members in some cases are very small indeed, the hole in the tubular body portion being exceedingly small, and

in some cases hard to find, and therefore it is greatly to be desired that the inner end 21 of the click which is to be inserted into the tube be made as small as possible to facilitate its ready entrance thereinto. Then again, it is also found in practice that by hammering or swaging this inner end, in addition to making the same smaller and easier to enter the tubular member, it also imparts to the spring arms 1818 greater stiffness and therefor greater power to resist the possibilty of becoming disengaged when an unusual strain is brought to bear upon it. With these ends in view I have hammered or swaged the inner end portion 21 causing the stock of the outer arms 18 to lap or lay around the oval shaped stock of the inner members in the manner best illustrated in Fig. 5.

By my improved construction it will be seen that the click is made of a single piece of wire, the loop portions 16 being formed in the middle thereof and the middle body portion being provided with two spring arms set directly opposite 'each other, whereby each arm assists in holding its opposing arm 7 inengagement with the lip 14 ofthe tubular 7 having a swivel eye connected thereto, the opposite end of said body having its edge member when the click is inserted therein.

Then again by my improved construction as the eye and the spring arms are formed integral with the rest of the member there is no necessity for the use of solder in its construction, the use of solder being,as is well known, detrimental to the practical construction of such devices, as the heat has a tendency to draw and destroy the temper of the springs.

I claim: 1. In a chain connector, the combination with a tubular body having an open end surrounded by a flange, of a click formed of a single piece of wire bent upon itself at its middle to form a loop at the bent end and providing a middle portion formed of two parts, each of said parts being again bent upon themselves to form spring arms to engage said flange, the wire at said last mentioned bends being compressed together to increase the resiliency of said spring arms, the outer ends of said spring arms having outwardly turned 'manipulating ends.

2. In a chain connector, the combination formed single piece of wire doubled at its middle upon itselfforming a loop at the end and providing a middle body portion forming two parts, each of these,

parts being again doubled back nearly upon:

form a loop at the bent end and providing a middle portion formed of two parts, each of said parts being again bent upon themselves to form spring arms to engage said flange, thewire at saidlast mentioned bends being compressed together to increase the resiliency of said spring arms, the outel. ends of said spring arms having outwardly I turned manipulating ends. 7

In testimony whereof I affix my'signature in presence of two witnesses. Y
