LIGHrIiI mx'runn Specification of Letters Patent.

Application filedJ'une 3, 1913. Serial No. 771,447.

To all whom it may concern:

'Be it known that I, WILLIAM P. HORN, a citizen of the United States, residing at Mount Vernomin the county of /Vestchester and State of New York, have invented certain new and useful Improvements in Lighting-Fixtures, of which, the following is a specification. f V r This invention relates to lighting fixtures, and has for its object to provide a globe or shade so constructed and supported that it can be readily cleaned without removing the same from the fixture.

The invention is particularly serviceable with fixtures located in high or not readily accessible positions.

Ordinary globes especially bowls, etc., for indirect lighting collect dirt, and need frequent cleaning; this cannot readily be done except by removing the globe from the fixture, which is inconvenient, especially with large globes, or those placed high up.

I provide a globe, or shade of the lantern type, as an example, composed of a number of segments which are hinged at the top to a support and which can be opened from below so that the inside of the globe can be cleaned by a brush or the like, which can be placed on a pole if necessary, or, a lamp in the/fixture can be renewed by opening the globe, and by the use of any of the known devices for placing a lamp in position, in case the fixture cannot be reached conveniently by hand. The fixture gives the benefit of indirect lighting, with the advantages of an open globe or shade.

One embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a globe and fixture embodying the improvement, the open position of the globe segments being indicated in dotted lines. Fig. 2 is a vertical section. Fig. 3 is a section on the line 3-3 of Fig. 1. of a modification.

Referring specifically to the drawings, 6 indicates a pipe or hanger, of any desired type, provided at its lower end with a socket for the lamp 7 or otherilluminating device, and forms a conduit for the wires in the event that an electric lamp is used. A gallery or top ring frame 8 is supported on the pipe by means of a collar 9 and arms 10, or other suitable devices. This ring or gallery may be made of metal.

Fig. 4 is a vertical section Patented Nov. 11, 1913.

The globeconsists of a plurality of scgv ments or panels 11 properly shaped and proportioned to inclose the lamp when closed. In the drawings, a fixture of the lantern type is illustrated. segments is hinged at the top, as indicated at 12, to the lower edge of the ring frame 8, and when they are closed they inclose the lamp and diffuse the light thereof. I preferably provide an interior skeleton frame consisting of bars 13 which are fixed to the ring frame 8 at their upper ends and which are shaped to conform to the curvature or outline of the globe and are joined at their Each of these lower ends to a threaded tube or stem 14- lo- 7 cated at the bottom of the globe. The glass segments 11 close against this frame. They are closed by means of a pull cord 15 which extends through the tube 14% and has branches 16 each of which is connected to "one of the segments ator near the lower end thereof. A sleeve 17 screws on the lower promoting end. of the stem 141- and is provided with a cross piece or device 18 for turning it either by hand if the fixture can be so reached, or by means of a fork on a rod, for high fixtures. At its upper end the sleeve 17 is spread to form a cup 19' which, When the sleeve is screwed up, closes against the lower ends of the segments 11v and holds them in closed position.

in against the frame 13, and the sleeve 17 is screwed up to engage the cup 19 under the ends of the segments and clamp the same in closed position, the edges of the segments closing against each! otherto form a complete globe.

Instead of the skeleton frame 13, a rod may extend down to the bottom of the globe, from the pipe 6, and provided with a tubular part or stem for the pull cord 15, and for the clamping sleeve 17, as shown in Fig. 4:. This arrangement avoids any shadows from the arms 13, and is particularly serviceable with cluster lamps, with the rod or stem 14F depending from the hanger pipe 6.

The invention is not limited to the parof globe sections hinged attheir upper ends I to the frame and adapted to swing to open or closed position, and means extending from the stem and connected to the sections to draw the lower ends together, to close the globe.

2. A lighting fixture comprising a frame,

a plurality of globe sectionsfhinged at their upper ends to the frame and adaptedto swing to open or closed position, and a pull cord having branches connected to the re-' spective sections to draw the same together, to close the globe.

3. A lighting fixture comprising a top frame, a stem supported below the same, a

plurality of globe sections hinged at their upper ends to said frame, and adapted to 'wing toward or from each other, and a clamping device mounted on the stem and movable to engage the lower ends of the sections and hold the same in closed position.

4. A lighting fixture comprising a top frame, a tubular stem supported below the same, a. plurality of globe sections hinged at their upper ends to the frame, to swing toward or from each other, and a'cord extending through the stem and connected to the respective sections to draw the same together.

5. A lighting fixture comprising a top frame, a threaded stem supported below the same, a plurality of globe sections hinged at their upper ends to the frame, to swing to or from each other, a clamping sleeve screwed on the stem and engageable with the lower ends of the sections to hold the same in closed position, and means extending through the stem and connected to the sections to draw them together.

6. A lighting fixture comprising a hanger provided with lamp-supporting devices, a top frame supported thereon, a plurality of globe sections hinged at their upper ends'to the frame andinclosing the lamp, and adapted to swing toopen or closed position, a stem connected to the hanger and located at the bot-tom of theglobe, and means mounted on the stem vto hold the'lower ends of the sections in closed position against the same.

,7. A lighting fixture comprising a hanger provided with lamp-supporting devices, a top frame supported thereon, a skeleton frame depending from the top frame, a plurality of globe sections hinged at their upper ends to the top frame and adapted to inc-lose the skeleton frame, a tubular stem attached to the lower end of the skeleton frame. a cord extending through the stem and connected to said sections to draw the same toward the skeleton frame, and a clamping device mounted on the stem and engageable with the lower ends of the sections to hold the same in closed position.

In testimony whereof, I aflix my'signature in presence of two witnesses.
