6 Claims.

The present invention relates todevices` for connecting two or more wires, usually square in cross-section, though wires of otherl forms `may be employed, to form various kinds of useful and ornamental articles, such as display stands for supporting and displaying various articles of jewelry and like objects, baskets, trays, music, magazine and letter racks, and a great many kinds of articles constructed of sections of vvire` or bars secured together, both curved and.- straight, parallel or intersecting with each other, in a great variety of patterns and designs.

Usually, the wire members ci such articles have been secured together by soldering, or brazing, or in some cases by means of rivets, but the methods heretofore practiced are open to various objections. It is difficult in soldering to always make a clean job, and the joint is weak and brittle. It is usually desirable in fabricating such structures as those in question, to first finish the different wire and frame members and give them the desired plating, and then secure them together. When plated withV chromium, which is largely used today as` an ornamental finish, the parts cannot be soldered together, while if ,the Wires are soldered together before plating, they cannot then be completely and effectively plated withV chromium, and some other metals, as the soldered joint will not be effectively covered. While the same diiculties do not arise to the same extent with gold and silver plated parts, yetv such plated parts cannot beV soldered together without tarnishing and discoloring the finish at and near the so-ldered joint, and this is likewise the case with most other kinds of plating.

Such separate fastening means as rivets or screws are unsightly, and tend to mar the appearance of the article, which is an important matter, as a pleasing appearance is a primary 40 consideration in the construction of such articles,

and the work of securing the parts together by screws or rivets is inconvenient and slow, so that the cost of production by employing such fastening means is excessive.

The object of my invention is to provide sightly and ornamental connecting devices for securing together the wires or bars of which articles such as those before mentioned are composedV which shall to a large extent obviate the objections mentioned, and which shall on the other hand possess the correlative advantages of being strong and durable, clean and attractive in appearance, easy and quick of application in assembling the parts, adaptable to the rapid and economical production of articles of almost every conceivable pattern and design, and which in general shall facilitate the production and manufacture of such articles and be highly desirable for the purposes in view. Although my invention is particularly adapted for use in making up display frames ci wire which areY square or rectangular in cross-section, yet it is not limited exclusively to the employment of wire oi that kind.

In carrying out these general purposes I have devised forms of my invention particularly adapted for connecting groups oi parallel wires, Wires which` intersect one another, connectors for connecting one or more wires to a. base support, connectors for connecting a plurality of wires to a central shaft, and connectors for supporting dis-` play attachments, as will hereinafter be described in de-tail in the various embodiments of my invention illustrated in the accompanying drawings, the essential elements of my invention being more particularly pointed out in the appended claims.

As will be apparent from comparison of Figs. 1, 7, 15 and 17, my invention is not concerned at all with the particular design of any given display rack or other article, but relates only to the connecting members, or connectors, for securing the structural elements of the frame to each other.

Describing first the form of my invention illus- .trated in Figs. 1 to- 6, inclusive, which illustrates a connector device adapted to connect three parallel square wires, the connector includes three members, one of which is a body portion including a block I, formed with an intermediate flat transverse wall portion which in the present instance is disk-like in shape, though it may be square or polygonal or of other shape from the opposite sides of which extend on the one side, which for convenience of description will be termed the lower side, a pair of engaging portions 3 3; and on the other, upper side, a pair of similar, but longer engaging portions 4 4, the outer faces of the portions 3 and 4 being formed on cylindrical surfaces, axially of a line passing through the center of a lower slot 5 separating the sections 3 3 and an upper slot 6 which separates the sections 4 4, see Figs. 5 and 6. The ends of the lower portions 3, and likewise the ends of the upper portions 4, it will be noted, are formed in a convex surface, the portions extending or projecting beyond the faces of the wires in the slots (see Fig. 5) so that they may be swaged down thereover, as hereinafter described.

The slots 5 and 6 are of such size as to snugly receive the square Wires '1 of which the framework of the rack, whatever its design, is constructed.

Another member of the device is a spacing ring 8, which for the sake of symmetry of appearance, though not necessarily, is of the same thickness and external diameter as the disk portion 2 of the body of the connector and the bore of which ts smoothly over the upper engaging portions 6 0i' the connector.

The remaining member of the connector is a locking pin 9 of suitably hard metal arranged to be received within the slot 6 and within the opening inside the spacing ring, this pin being provided vnth opposite sharp projections extending (before the parts are secured together) beyond the planes of the upper and lower faces of the spacing ring. In the present instance this locking pin 'is in the form of a hard doubleheaded rivet, the heads of which are formed with sharp edges, which, after the parts of the frame have been assembled and the joints then closed forcing the parts together, will bite into the wires 'l (which are of softer material) and thus prevent longitudinal movement of the engaged wires in the slots of the body of the connector.

The wires 'l to be secured together being engaged in the slots of the connector and the parts of the connector being assembled as shown in Fig. 1, with the lower wire between the portions 3 3, and the intermediate wire in the lower part of the slot 6 between the portions 4 4 and the together (see Figs. 2, 3 and 4). In the completed? joint the lower wire is securely held by the firm grip of the turned-in edges of the portions 3, while the intermediate and upper wires are locked together by the pin 9, and similarly secured in the slot 6 by the inturned edges of the portionsy 4. The spacing ring 8 of course prevents any longitudinal displacement of the interlocked intermediate and upper wires and pin as a whole in the groove 6.

In case but two parallel wires are to be connected together by one connector, a more simple form of connector may be employed, in which the disk portion 2 is connected on both sides with engaging portion (all marked 3) of such length as to receive but a single wire, as shown in Fig. 5a.

The base plug of the display rack (see Figs. 1 and 14) is arranged to support said rack through a single horizontal wire 1, and therefore consists of a block I 0 formed with a depending axial screw by which it secured to the base block Il, and having the convex top faces of its upper portions |2 |2 arranged to be turned down on the wire as before described.

In case a pair of frame wires are to be engaged by a base plug, the upwardly extending separated portions of the plug will be made longer, and a spacing ring 8 interposed between the wires, a looking pin 9 being preferably also in such case interposed within the spacing ring.

In case three frame wires are engaged by the base plug, as illustrated in Figs. 7, 8 and 9, the upwardly extending portions of the base plug, marked I 3 I3, are of such height as to permit assembly of the three wires, separated by spacing rings 8 on each side of the intermediate wire, and locking pins 9 and arranged within the spacing rings.

'I'he forms of connector above described provide also for means for displaying cards and''i brackets to the display frame. In Figs. 9 and 10 I have illustrated a card holder I4 in the form of a conical chambered block adapted to seat over the base plug of such a form of display stand as illustrated in Fig. '7 or over the top of either one of the vertically disposed connectors illustrated on opposite sides of the center of the lower portion of the display stand shown in Fig. 1. The plug is hollowed out on its lower side to provide a depending skirt which is notched to t over the Wire below it, and slitted at the top to receive a card.

In Figs. '7 and 8, I have shown a display attachment which may be employed in the same manner. This display attachment comprises a block I5, recessed below to fit over the vertical connector member and having a concave face at the top to support the convex bearing portion I6 of the bracket or shelf, marked I'I, the portion I6 being slotted to receive a screw which is threaded in an axial Seat in the block l5. As is obvious, the slotted connection provides for adjustment of the shelf on its support.

In most designs of display stands, it is necessary to provide for connections of wires which cross each other, usually at a right angle. A form of connector which I have devised for this purpose is illustrated in Figs. 11 and 12, this connector being formed with a central disk-like portion I8, on one side of which are formed the portions IS--IS separated by slot 20 to receive a wire 1a, and on the other side of Which are formed the portions 2l-2I disposed so that they are separated by a slot 22 extending at right angles to the slot 20, to receive a cross wire 1b, the con- Vexed end of the portions being swaged down over the engaged wires as before explained. A plurality of the connections may be employed to connect any desired number of wires with any desired number of cross-wires, as for instance as illustrated in Fig. 11, in which the single wire, marked 1a, is connected by a pair of connectors to the wires 'Ib and 1.

From the explanation already given` it will be obvious that groups of `parallel wires may be connected with a single intersecting wire or a group of parallel intersecting wires by a single connector, the engaging portions of the connector being made of such length as to accommodate the number of parallel wires connected, and spacing rings and locking pins used between the wires as herebefore explained.

A modified form of my invention is illustrated in Figs. 15 and 16, in which the connector device is used to connect frame-wires 23 (in the present instance two in number) and a card holder 24 to upper and lower sections marked 25 and 26, of a vertical shaft forming, a supporting standard for a display stand. This form of connector consists of a central body portion 21, screw-threaded at top and bottom to engage the sections 25 and 26 of the central standard, and integral therewith engaging portions separated by vertical slots adapted to receive the frame wires 23, the peripheral faces of these sections being convex, whereby they may be swaged down over and upon the wires to rmly secure them in their grooves. lIn the display frame shown in Fig. 15, the wires 23 are diametrically opposite curved wires arranged to produce an ornamental effect and afford a support for display shelves or holders, or the like, and the front intermediate wire is slit to serve as a card holder.

In the display stand embodying a similar modied form of my invention shown in Fig. 17, the conector is formed with four wire-receiving slots providing means for connecting the four ornamental legs 28 through which the vertical central shaft and other parts of the framework of a display stand are Supported.

It is obvious that my novel connectors above described lend themselves to rapid and economical construction of all designs of display frames of the type described. 'I'he wires, previously cut and bent to proper shapes can easily be assembled by sliding them in the connector slots and the parts quickly secured together by proper tools. Furthermore, the connectors enhance the ornamental appearance of the display frame, and contribute in that respect to the value of the invention.

I claim:
