GLOBE-HOLDER FOR LAMPS.

Application filed June 24, 1914.

To all whom it m (1 concern Be it known that I, FREDERICK J. HUM- PIIRI'JY, a citizen of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Globe-Holders for Lamps, of which the following is a specification.

This invention relates to improvements in globe holders for lamps.

In using the term globe holder in this application I intend that it shall be considered to embrace shades, reflectors and the like where they are supported in substantially the same manner as by my holder, which is adapted for holding shades, reflectors and the like, and is adapted for use in both gas and electric lamps.

The main objects of this invention are to provide an improved globe holder in which the parts are simple and economical in struc ture and easily assembled and when assem bled cannot become accidentally disassembled, and at the same time to provide a structure which effectively supports the globe in a central position and one which is easy and simple to operate.

Further objects, and ob ects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a detail side elevation of a lamp structure embodying the features of my invention. Fig. II is a horizontal section on a line corresponding to the broken line 22 of F i I. Fig. 'III is an enlarged detail vertica section on a line corresponding to line 33 of Fig. II. Fig. IV is a plan view of one of the retaining members 13 in its extended or fiat form.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the body or casing 1 of the lamp, which may be of any suitable design, is provided with a cylindri- Specification of Letters Patent.

cal globe holder collar or gallery 2 at its lower end having an int-urned flange 3. The globe 4 is inserted into the bottom of the gallery and is provided with a flange with which the supporting. ring 5 engages, as is well understood in the art. The supporting ring 5 is formed of wire and has a rear loop '6 and side loops 7 projecting laterally to constitute supporting fingers. The collar or gallery 2 has a rear slot 8 and a pair of side slots J in which the supporting fingers are disposed as is shown in detail in Fig. II. The front ends 10 of the supporting ring are crossed and are disposed tangentially through the spaced front slots 11, the ends being crossed within the collar between the slots, as shown in Fig. II. The side slots 9 are of such length as to ermit lateral and longitudinal movement of the side loops or fingers 7 therein. The rear slotis of such length that the rear loop or finger (3 is a sliding fit therein. The front slots 11 are of such length that the contractive action of the ring holds the ends 10 against the outer ends of the slots and this normally holds the side fingers 7 against the front ends of the slots 9. This effectively centers the ring.

To expand the ring for removal or insertion of the globe the two ends of the ring are grasped, as between the thumb and finger and pressed together, which throws the side fingers 7 outwardly and rearwardly in the slots 9 and forces the finger 6 rearwardly in the rear slot 8. When the band is released the contraction of the spring not only causes it to engage the globe but also centers the ring as described.

The extreme ends of the ring are formed into loops 12 to provide finger pieces. The front slots 11 are preferably arranged with their centers in slightly different planes, as illustrated, so that the ends 10 are properly supported in their crossed relation. The fingers or loops 6 and 7 are all in the same plane and are preferably straight, as shown. This permits the parts being quickly and easily assembled.

To prevent the accidental displacement of the side loops from the slots I provide retaining members 13. These retaining members are, in the structure illustrated, circular disks of sheet metal which are inserted through the'loops and folded outwardly over the ends of the loops. The retainers are provided with opposed notches 14 which are engaged with the sides or arms of the loops, thereby supporting the retaining members so that theyfmay be readily folded over the ends of the loops, as by means of a pair of pliers, and also to assist in retaining them in place. The retainers thus formed have an attractive and finished appearance and do not detract from the appearance of the lamp. While the retainers permit free movement of the loops in the slots 9 they effectively retain the loops in the slots.

My improved globe holder is very simple and economical in structure and the parts are simple and economical to assemble and it is very easily operated and very elfectively supports the globe.

Having thus described my invention, what I claim as new and desire to secur'e by Lettors Patent, is:

l. l he combination with the collar of a light fixture having a rear slot, a pair of opposed side slots and a pair of spaced front slots, of a ring formed of wire disposed within the collar and having side and rear loops engaged in said side and rear slots thereof, the ends of the ring being crossed and disposed tangentially through the front slots and normally engaging the outer ends thereof, the length of the side slots being greater than the width of the side loops, per

mitting lateral and longitudinal movement of the side loops and longitudinal movement of the rear loop in the slots as the ring con tracts and expands, the side loops normally engaging the front ends of the side slots, and retain ng members formed of sheet metal disks having opposed notches in their by the retaining member is supportedron the loop.

3. The combination with the collar-of a light fixture having a slot therein, of a supporting ring formed of wire provided with a loop constituting a supporting finger dis posed through the slot in the collar, and a sheet metal disk disposed through the loop,

folded outwardly over the end thereof and having notches in its edges engaging the loop.

In witness whereof, I have hereunto set my hand and sealin the presence of two witnesses.

FREDERICK J. HUMPHREY.
