CALIFORNIA V v CLAMP SUPPORT FOR GLOBES Application filed August 31, 1931. Serial No. 560,342.

This invention relates to a clamp support for light globes whereby the globes are effectively and securely held against d1splacement, and further, may be readily removed 'when it is necessary to clean them orv replace the light.

An object of our invention is to make it unnecessary to remove or unscrew the screws which are commonly used for the support of light globes. This being accomplished by a novel clip which engages the screw.

Another object is to provide a novel clamp support for globes which is simple in construction,inexpensive to manufacture, which may be readily installed upon existing types of light globes, and which can be placed upon any globe support either of the interior or exterior type. The clips ofour support being so mounted that they will always engage the screws in the globe support; 7

Other objects, advantages, and features of invention may appear from the accompany ing drawings, the subjoined detailed description, and the appended claims.

Referring more particularly to the draw ings, the numeral 1 represents a globe of the type commonly used for exterior lighting, such as streets or the like. The globe 1 rests on a support 2 of usual and well known construction. The support 2 is provided with a plurality of screws 3 which heretofore would extend throughand engage the globe to hold it in position. When using our ring these screws are threaded out until they merely pass through the support, and do not engage the glass globe.

Due to the imperfection of manufacture, the screws are not accurately spaced apart, but vary in difi'erent supports as much as half an inch more or less, also different supports have a difl'erent number of screws therein. Our invention consists of applying a band or ring 4 to the globe 1 adjacent to the bottom or top thereof. depending on how the globe is hung. The globe is provided with a flange or bead 5 against which the ring bears. The band is fixedly attached to the globe by means ofa screw or the like 6, which screw extends through the-overlapping end of the band. One end of the band is slotted as at 7 and the screw 6 extends through this slot, thus the ring can be expanded or contracted to compensate for different size globes. A rality of clips 8 or may be integrally formed therewith.

plu-

are attached to the band 4- These clips extend over the edge of support i 2 and are provided with horizontal extensions 9, which extensions engage the screws 8 so as to hold the globe 1 securely in position. The

extensions 9 may be toothed or serrated.

Because of vibration, strong wind or other causes the extensions 9 may disengage. the screws 3. To overcome this possibility we have arranged a latch 11 which is pivotally secured to the clips 8. This latch is pro vided with indentations'or recesses 12 which other means.

, ment.

fit over the screw 3 when the latch is swung downwardly, thus the ring 4 is held against any rotary movement, and the clips can not disengage the screws. The clips 8 are formed of spring material so that they will press tightly against the screws, and thus outside of the support 2, a single hole is formed in the flaps and the screw is passed through this hole. However, t is necessary first to remove the head of the screw in order that this type of clip may be used,

In Figure 6 the clip 16 is provided with a depending flap 17 in which an inclined slot 18 is formed. In this instance, the screw is passed into the slot and the globe is rotated with the ring thereon, so that the screw is forced into the upper end of the slot 18, thus springing the clip down and the screw will be firmly engaged.

The screws in the lamp support are not accurately spaced apart, and also the number of screws vary. Therefore, we have provided a means of adjusting the clips along the ring so as tocompensate for these differences. In Figure '1' the ring l has attached thereto an outwardly extending bar 19, this bar suitably attached to the ring such as welding or The clip 20 is sli-dably mounted on the bar 19, one end of the clip being bent around the bar as shown at 21. It will be evident that the clip can be moved horizontally from one end of the bar 19 to the other, or an amount necessary to engage the screw.

In Figure 8 the clip 22 is slidable on the ring itself, that is one end the clip is bent or formed around the ring 4 as shown at 23.

In Figure 9 the globe base or support 24 is formed with a plurality of rests 25 therein, A wire ring 26 is adapted to encircle thelight globe, and the wire is provided with outwardly pr'ojecting lugs 27 integrally formed in the wire. These lugs enter the rests and thus hold the lamp globe a; .inst displace- The ends o1 the wire 26 are connected by means of a toggle clamp 28, this clamp projects through an opening 29 which is formed in the base 24.

In Figures 10 and 11 a wire clamp 30 ea circles the globe and the ends of the wire are attached together by a toggle clamp 31. A plurality of spring clips 32 of any type previ ously described. These clips are slidably mounted on the wire 30. due to the fact that one end of the clip encircled the wire 30 as shown at 33. The clips can thus be moved horizontally to engage one of the screws 8.

Having described our invention, we claim:

1. A clamp support for globes comprising a case in which the globe extends, a plurality of engageable members extending from said case, a globe, a ring, a means securing said ring about the globe, a plurality of clips extending from said ring, said clips engaging the members extending from the case, and a supporting lip on each clip upon which the globe rests.

2. A clamp support for globes comprising a case, a globe extending into the case, a plurality of engageable members extending from the case, a ring encircling the globe, means securing said ring about the globe, a plurality of clips extending from the ring, a horizontal section on each clip, said horizontal section. engaging the said members, and latch means mounted on a clip and adapted: to engage one of. said members whereby said ring and globe are held against movement.
