F. DEUTSCH GLOBE WITH APPLIANCES MOUNTED FOR ATTACHING THEM Filed Jan. 23, 1932 INVENTOR 7Q/ATTORNEY Patented Jan. 9, 1934 UNITED STATES PATENT OFFICE GLOBE WITH APPLIANCES MOUNTED FOR ATTACHING THEM Fritz Deutsch, Kreuzlingen, Thurgau, Switzerland Lamps or globes heretofore have been attached to walls or suspended from ceilings or lampstands by means of bayonet fittings, screws, or bowl holders. An object of my invention is to improve upon the above-mentioned appliances.

The feature of the appliance herein described for attaching the globes of electric light fittings to their supports in the ceiling or to a pendant or chandelier, permitting such a connection to be made in a. far safer and more convenient manner than hitherto known, is that the glass has first been provided with fittings of a different material which are embodied in the glass. The customary method is to connect the pure glass to the lamp.

With the above features and objects in view:-

Figure 1 is an expanded partly sectional and partly a front view showing a fragmentary section of a globe with novel means for retaining the same in position;

Figs. 2 and 3 are sectional fragmentary views showing the glass-holding elements being fixed onto the stationary fastening armature member depending from a ceiling;

Fig. i is a bottom plan view of Fig. 1 showing the locking member for engaging the fixed depending armature member.

In the preferred embodiment shown in Figs. 1 to 4, the glass member a, having a broad horizontal flattened shoulder b, surrounding an opening to which, a flat rim 0 is connected by segment parts f. These segments parts I are held by means of screws it passed through holes g which catch in nut holes 2'. The pressure between the segment parts f is again eased by interposing gaskets ;i. But instead of using a cylindrical threaded member d, parts out out in the form of key holes 0 are provided in the rim 0 and also in the parts f as far as necessary. In the porcelain ceiling piece n attached to a ceiling, not shown, and adapted for holding an electric light bulb therein there are pins 10 depending from the ceiling, which have heads q. Said heads q have springs r with spring plates 3. The porcelain ceiling piece may be used in connection with the broad part of the key hole 0 over these pins p, with their attachments as shown in Fig. 2, whereby the spring plate 8 is in a position slightly below the edge of the hole 0. Thus the hole 0 is covered in its longitudinal direction with a perpendicular profile part, beginning at its one end with an inclination t, and terminating with its other end in a catch 11.. Whenever the glass is turned toward the direction of the arrow, as in Fig. 2, the spring plate 5 slides along the guide slot t and presses the spring r against the head q, and after catching in the snap u, as shown in Figs. 2 and 4, remains under tension. By this contrivance, the glass will be firmly pressed to the upper part and cannot release itself, but at the same time it is easily detachable. By this arrangement of parts, no shadows are thrown and a superior light with fine efiects is possible. Furthermore, the device in the embodiment is applicable not only to circular glasses, but also, for instance, to oval or case-like glasses as well.

It is understood that various changes or modifications may be made as to form, structure and materials used without departing from the spirit P and scope of the invention as defined in the accompanying claims.

Having now particularly described and ascertained the nature of my invention, and in what manner the same is to be performed, I declare that what I claim as new is:-

1. An appliance in combination with a glass globe having a rimmed portion, comprising a depending catch pin with a spring and a spring cap thereon, and a pair of segmented flanges, one on either side of the rim portion of the globe and having central openings therein, one of said flanges having leading from the central opening thereof an inclined slotted extension, for insertion of the pin through the openings of said flanges, said spring cap being adapted to glide along the slotted extension to contact tightly therewith whereby a connection is formed between the flanges and the catch pin for retaining the globe.

2. An appliance in combination with a glass globe having a rimmed portion, comprising a depending catch pin with a spring and a spring cap thereon, a pair of annular flanges, one on either side of the rim portion of the globe and having central openings therein, one of said flanges having leading from the central opening thereof a downwardly inclined slotted extension, for insertion of the pin through the openings of said flanges, said spring cap being adapted to glide along the extension and form a tight contact therewith whereby a connection is formed between the flanges and the catch pin for retaining the globe, and means for maintaining a permanent clamping connection between the rim and the flanges.

3. An appliance for attaching a glass globe to ceilings, having a peripherally projecting rim thereon, comprising a depending ceiling piece. an interlocking pin depending from said piece,

a pair of superimposed annular flanges containing the rim therein, and having central openings therein, and means for retaining the rim clamped between the flanges, the openings of one of the flanges forming with the lower flange a downwardly inclined slotted extension whereupon insertion of the pin through the openings of the flanges and on movement of the clamped rim, said pin engages the lowermost part of said extension.

4. In a ceiling appliance for a glass globe having a peripheral rim, the combination with a stationary interlocking pin depending from the ceiling, having a spring and spring cap thereon, of a pair of superimposed annular flanges clamping said rim and maintaining slotted engagement against the action of the spring and cap of the pin, resilient means intermediate the rim and the flanges for preventing fracture, and means holding the flanges in clamped position.

5. A removable appliance for attaching a glass globe having a rim, comprising a pair of annular flanges for sandwiching the rim of said globe, said flanges having an opening in superimposed position, the upper flange having an inclined slotted extension leading to the lower flange, while said lower flange has a slot with a catch leading from the opening, means for retaining the rim in clamped position between the flanges, and an interlocking pin, having a spring and spring cap thereon, whereby upon passing said pin through the openings in the flanges and moving the latter, said spring cap yieldingly slides along the slotted extension and makes contact with the catch on the lower flange to retain the globe in stationary position.

FRITZ DEUTSCI-I.
