Specification of Letters Patent.

Application filed July 15, 1910. Serial No. 572,193.

To all whom 'it may concern. 7

Be it known that I, Tnoarss J. LITLE, J r., of \Voodbury, Gloucester county, New J ervsey, have invented a new and useful Improvement in Globe-Holders for Lamps, of which the following is a full, clear, and exact description, reference being'had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side view of one form of lamp embodying my invention; Fig. 2 is a detail sectional view hereinafter more fully described; Fig. 8 is a section on the line IIIITI of Fig. 1; Fig. t is a side view of a modified form of my invention. Fig. 5 is asection. on the line VII-V1I of Fig. 4. Fig. (3 is a side view showing another form of the invention; and Fig. 7 is a detail view of a heat-insulated wire which I prefer to use as the clamping means.

My invention is designed to provide a globe holder for inverted lamps which will obviate the use of the screws commonly employed for securing the globes, and which are. liable to be set up too tightly and break the globe, and Whieh'also require considerable time in screwing and unscrewing.

In accordance with my invention, I pro vide a novel form of globe-holder in the form of an expansible clasp adapted to embrace the upper or neck portion of the globe, and having means whereby it may be quickly secured in clamping engagement with the globe and quickly released from such engagement.

The nature of my invention will be best understood by reference to the accompanying drawings, in which l have shown several ditl'erent embodiments tl1ereof,'which will now be described, it being premised, however, that various changes may be made in the details of the construction and arrangement of the parts without departing from the spirit and scope of my invention as defined in the appended claims.

.llcferring first to that form of my invention which is shown in Figs. 1, 2 and 3, the numeral 2 designates the casing of the lamp having the lower globe-holding ring .or llangc 3 and 4 is the globe or shade. Placed within the ring or tla'nge 3 is the globeholder, which consists of a spring metal ring 1'. preferably of wire, held in place by a bend or loop (3 l'orincd in its central portion and projecting through aslot 7 in the ring or flange 3. The end portions of the wire are brought out through an elongated slot 8 at'the opposite side of the ring or flange 3 from the bend 6. and terminate in knobs or buttons 9. The ring 5 is preferably supported at two or more points by means of swinging arms 10, which are secured at their upper ends to the upper portion of the ring 3 by screws or pins 10, which will permit suilicient freedom of movement of the arms 10 to permit the ring 5 to assume a central position with relation to the globe holder. It will readily be understood by those familiar with the art that these arms 10 may be connected to the globe holder in any manner, providing the arms are arranged to have sutticient movement to permit the ring 5 to assume its pro} )er'p0sition. The elasticity of the ring 5 normally tends to hold said ring in its extended or expanded position, to receive the globe. After the globe. has been inserted; the .free

ends of the wire are pressed'toward' each other and the knobs or buttons 9 cleneh over. or iinlel'lock with each other; in the ith nnershown, thereby lroliling the ring 5 in secure ch mping engagement with the glttliefi When the knobs ,or buttons are thought together and clenched over each other in this manner, the depending swinging arms 10 move inwardly and upwardly, forcing the shoulder of the globe up against the lower edge of the globe ring 3, thus giving a better appearance.

In the modification shown in l igs. 4 and 5, the holding ring I)" is constructed Sllllillll} to the ring 5 in the form first. described, but has one of its ends secured in a. relatively fixed position by being projected through the globe ring, while its other end is brought outwardly through an elongated slot 8" of said ring. The lower wall of this slot is provided 'ith a plurality of ratchet teeth 14, with ny one of which the end, portion 5" of the ring may be engaged, thus accommodating the device to globes having different sizes of necks.

In Fig. (3 I show a form similar to that. of Figs. 4; and 5, except that the wall is provided with two slots 8", the lower wall of each slot liaving iitchet teeth It". Either cud portion of t] o ring 5" may be engaged with any of thoh'cth in its containing slot,

thus more fully accommodating the device for globes of diflerent sizes of necks. In this figure I have shown the ring 5 supported by means of swinging arms 10, similar to those shown in Fig. 1.

In Fig. 7 I show the form of clamping ring or wire which I preferably use in any or. all of the above forms. Such wire 5 is preferably covered with a heat-insulating layer 21, which may be made of asbestos or other suitable poor conductor of heat. The wire may be covered by wrapping it with a tape of the desired material, or by covering it in any other desired way. This heatinsulating cover avoids injurious heating of the Wire, and also liability to crack the globe or shade.

The advantages of my invention result from the provision of an extremely simple and inexpensive form of globe holder which obviates the use of the ordinary screws and which add but little to the expense of the lamp.

W'hat I claim is l. A globe holder comprising a body portion, a spring metal member adapted to encircle and clasp the upper portion of a globe, swinging arms connected to the body portion for supporting said member and means for positively drawing said member into clamping positionand for holding the same in such position; substantially as described.
