STTES WILLIAM 0. KLEINE,

CLAMP Application filed December quickly operated holder for securing lightglobes as employed both in inside and outside lighting, it may also be effectively applied I'or automobile headlights in holding the lens in position, and in many other situations which will readily occur to the skilled mechanic, should occasion arise.

The invention consists broadly of a clamping device involvingtwo disk plates secured together and relatively movable rotatively to a limited degree and provided, mounted to oscillate on a fixed center, with reference to each other, with resilient clamp plates of comparatively thin metal mounted upon studs secured to one of the plates to engage slots in the other plate and actuated by the movement of the latter plate to oscillate the clamp plates into and out of looking position.

In the drawings,

Figure 1. is a perspective view of a globe holder for a pendant electric light fixture with my improved clamping device.

Figure 2 is a central vertical section 01 the device applied to both the top and bottom inside flanges of a light globe, such as is used for outdoor lighting.

Figure 3 is a detail section showing the clamping device arranged for holding two sections of a light globe, both section constructed of glass.

Figure at is a vertical section of a portion of a fixture, showing a modification of the clamp plate holder.

As illustrated in Figure 1, 1 isthe metal casing of a pendant light fixture used for interior or exterior lighting. Across the lower open end of the casing, within the depending rim 3, is secured a disk plate 2 by bolts 4, shown in Figure 2. Depending from this plate and secured thereto are a plurality ofstuds 5 which project through segmental slots 6, 6, in a second plate 7 mounted ior limited rotative movement with reference to the fixed plate 2.

The studs 5 are preferably three in numor CINCINNATI, onIo.

ber distributed 120 degrees apart, and they carry the clamping devices marked 8 as a whole. Each clamping device 8 comprises a member 12 mounted to turn on its stud. Where the two plates 2 and 7 are flat and located close to each other, in order to bring the clamping piece in proper position to engage the globe and to exert the pressure practically at right angles to the glass to be held, 1 preferably construct this member 12 of U-shape. The inner arm of the U-shaped member has an arm or hook 9 which engages in a slot 10 in the plate, and these slots 10 are radially disposed, while the slots 6 are on the arc of a circle.

The outer arm of the U-shaped member is formed with a fiat surface 13, upon which is riveted a thin, properly proportioned, spring metal plate 19 curved slightly outwardly.

lVhen the plates 2 and 7 are not located close together, as shown in Figure 4, the member 12, instead of being U-shaped, is simply a flat plate, and it will be understood that the shape of the member 12 is not of importance, its shape being dependent upon the position in which it may be necessary to locate the spring metal plate 19 in order that it may exert its pressure approximately in the direction of the axis of the member to be held.

In order to turn the plate 7 to cause the hooks 9 to actuate the clamp member and clamp plate, I provide a handle 14, which, in the case of the pendant fixture illustrated in Figure 1, projects radially through a slot 16 in the rim 3 of the metal piece 1. To co-operate with this handle 1%, I provide also, for this construction, a pair of fixed handles 17, 18, secured to the outside of rim 3, so that, to turn the disk 7 in either direction, the operator, with one hand, may hold the fixture by handles 17, 18, and pull the handle 14 towards either of the fixed handles 17, 18, while, at the same time, he can hold the globe with the other hand.

It will be evident from the construction described that actuation of the plate 7 in this way will turn the clamp members on the studs and rock the clamp plate 19 out or in to grasp or release the glass shade or globe 20 on the inside.

These holdersmay be employed both for the top and the bottom of the globe. As illustrated in Figure 2,- I show the clamp
