ELECTRIC-LIGHT FIXTURE.

.application med November 15, 1921. serial No. 515,383.

To all 'whom it may concern.'

Be it known that I, MAX H. THURNaUim, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Electric-Light Fixtures, of which the `following specification is a full disclosure.

My invention relates to an ornamental electric light bulb receptacle similating a candle-stick of miniature size intended to be used for decprativc purposes, such as dressing tables, Christmas trees, shop-windows, or the like, and which can be easily secured to the twigs of Christmas trees oi' the like.

Another object of the invention is to proy vide a cheap construction, 'easily handled, light in weight, and which can be'conveniently and securely attached in twigs of a tree.

The features of the invention will be more fully set forth in the description of the accoinpanyiug drawings, forming a part of this specification, in which:

Figure 1 is a central vertical section through one species of the electric candle.

Figure 2 is a top plan view of Fig. 1.

Figure 3 is an elevation of the structure of Fig. 1.

Figure 4 is a sectional view of the core shown in Fig. 1, on line 4 4, Fig. 5.

Figure 5 is a plan view of Fig. 4.

Figure 6 is a central vertical section of a modified form.

Figure 7 is a plan section on line 7 7, Fig. 6. t

Figure S is a side elevation .of Fig. 6.

Figures 9 and 10 are respectively a section on line 9 9, Fig. 10, and a plan View of the insulating disk for mounting the conductors and for mounting the portion of the base of the candle.

Figure 11 is a top plan View of the supporting base. u U

Figure 12 is a detail section on line 12 12, Fig. 11, illustrating the serrations upon the upper inner edges of the tangs designed f or gripping the support, in conJunctionl with opposing serrations upon the under side of the tray or base.

The form shown in Fig. 1 is for that species of toy candle wherein the bulb has a slipin connection with the candle tube for forming the electric connection.

A paper tube 1 is shown similating an ordinary candle in color and contour. At the lower end thereof is secured an insert or core 2, of insulating material, having a base flange 3, the core portion 2 bein inserted into the bottom end of the candiia tube. rIhe core 2 provides a stop or insertion limit for the bulb within the tube. Contacts 4, 5, are attached in diainetrieal relation to the core 2 and extend upwardly within the hollow tube, their extremities having the outwardly bent formations G, constituting spring-like clamps for frictionally engaging the bulb 7, and for making respective contact With the exterior of the bulb contact pieces 8, said contacts 4i, 5, being connected to the conducting wires 9, 10, just above the base 3. The base portion 3 is circular in plan, and is provided with a marginal notch 11. Upon the bottom of this base 3 is a candle-holder, having the form of a cap-like tray 12, (see Fig. 11), providing uptiirned scallops or flutes 13, which are purely ornamental. rihe upper portion of the tray is also formed with spurs 14, bent over the upper surface of the base 3, one of them being nterlocked with the notch 11 thereof. From the lower portion of tray 12 are downwardly projecting, semi-circular tangs 15, tapering in vertical plane,

`and forming conjointly, a screw-like clamp,

adapted to readily engage and be secured to a twig by the simple act of rotating the holder, i. e. screwing` it into place. The tanks therefore are in plane with the lower side of the tray 12 and spaced therefrom. The free ends of the tangs relatively extend in a corres onding direction and each terminate a s ight distance from the rear end of the other to provide a space for initially receiving the support to which the holder is to be secured, whereupon the holder is rotated, the tangs, under a screw-like action, clamping the su port between the tangs and the base side o the tray 12.

The tangs are punched from the base portion of the tray and the punching dies are of a construction which will cause a burr to be struck from the inner edges of the tangs i and corresponding edges of the openings iii the base of the tra formed by punching out the tangs. These lyiuired edges serve to provide rougliencd surfaces on edges for gripping or biting the support and thus hold the iixturc against accu ental release or re'- verse unfastening motion.

Fig. 6 shows a modification detail adapting the candle to receive the conventional screw bulb 16. ln this form a post o'r woodblock 17 is inserted with the lower portion of the tube and seated upon the insulating base 3". The base 3 is provided with pairs of slots 3b designed to receive and fasten the ends of the contacts, which ends are passed downwardly through one slot and upwardly through the adjacent slot and .laid against the upper face of the base, the wires 9 and 10 being attached thereto. A'filler piece 3 of insulating material ,is placed between the base 3 and tray 12. To provide the requisite contacts in this form, one of the wires 17 projects up one inside wall of the tube and is bent inwardly at the upper end to form the Contact 1.8 and the other wire 19 extends up the opposite wall of the tube and is provided with an inwardly disposed crimp 19 for engagement with the 'threads of the bulb, as a bulb retaining means.- The upper end of the wire is bent over the upper periphery of the tube to prevent its displacement. The device is easily made and assembled, and is lire-proof and reasonably staunch. It is also very ornamental in appearance and can he very quickly and easily applied, and it will firmly grip the conventional Christmas tree twig and be substantially held 1n place.

It will be observed from Figs. 3 and 4 that this holder'12 is a cup-like structure, similating the ornamental candle-holder, and, of course, this may be given any desired contour or ornamental effect.
