CHANDELIER-SUPPORT.

Speccaton of Letters Patent.

Patented Dec. 4, 1906.

Application filed July 14|1906- Selial N0. 326,254.

To all whom, t may concern:

Be it known that l, D V CUsHMAN, a citizen ofthe United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful lnprovements in Chandelier Supports, of which the following is a specification.

This invention relates to improvements in chandelier-supports, and has reference to the construction of a support for chandeliers to beplaced in buildings already erected.

At the present time where electric lighting is to be placed in old buildings or when it is desired to place chandeliers supported from the ceiling in buildings already built for lighting purposes other than electrical it is the custom to tear away a part ofthe upper floor where the building is of two or more stories and build between the floor-joist a sustaining-platform or erect cross-pieces between the joists for the purpose of holding the chandelier-stem to which the chandelier is attached. The floor is often of hard wood or car eted, and the method involves considera le time and displacement of the floor and consequent expense.

The object of the invention is to provide means wherebyA a chandelier for lighting purposes may be securely hung to a ceiling without injury to the upper floor and without unnecessary loss of time, which will be of few parts and may be economically constructed.

Vith these and other objects in view the invention presents a novel construction and arrangement of parts, as disclosedherein and illustrated by the drawings, wherein- Figure 1 is a sectional view showing my invention vertically mounted and in operative position upon a ceiling. Fig. 2 is a view of the engaging pin, partly torn away to disclose its apertured wall. Fig. 3 is a partlytorn-away view of the sleeve, and Fig. 4 represents a view of the screw-bolt used in connection therewith. Fig. 5 represents the threaded connecting-pin. Fig. 6 is a plan view of the ceiling-plate. Fig. 7 is a sectional view on line a b of Fig. 6. Fig. 8 is a view, partly broken away and partly in section, showing assembled parts, which will be more fully described hereinafter.

Referring to the drawings, the numeral 1 represents a floor-joist of a building, having secured thereto upon the upper edge thereof the floor-pieces 2, and secured to the lower edge of the joist are shown lathing-strips 3 and plastering 4 to represent the ceiling of a room beneath the floor.

l construct a sleeve 5, adapted to inclose the engaging pin 6. The sleeve 5 is provided with the aperture 7, having a threaded connection with the bolt-stem 8, the bolt-head 9 preferably being square. The engaging pin 6 is provided with a series of apertures 10 and with the screw-head 11, The ceiling-plate 12 is provided with a series of screw-holes 13, passing therethrough. near its outer edge, and with a series of wire or loom openings 14 near its center and with a larger central opening 15, adapted to contain the connecting-pin 16. The connecting-pin 16 has one end 17 adapted to make thread-and-groove connection with the end 18 of sleeve 5, the opposite end 19 of the connecting-pin being constructed to have thread-and-groove connection with the end 20 of a chandelier-stem 21.

As thus constructed the invention affords a ready means for hanging a chandelier and securing it to a ceiling of a room without requiring the customary blocking between the joists or injury to the floor. An opening is iirst made, as at 22, through the plaster of the ceiling for the mounting of my invention, and a vertical measurement is made of the distance from the lower surface 23 of the floor to the lower edge of the ceiling-plaster, as at 24, and, as is obvious, this distance will' vary, according to the width of floor-joist or thickness of plaster. The engaging-pin 6 is constructed of a less length than the width of the floor-joist, and the sleeve 5 has a less length than the width of the joist plus the thickness of plaster, and after the engaging pin is placed wit-hin the sleeve an adjustment of these parts is made in a manner so that said pin is made rigid within the sleeve by me ans of the bolt 25, passing through threaded aperture 7 of the sleeve and entering one of the series of openings 10 of the engaging in 6, thereby making an adjustment as to ength of the combined parts, so that the lower end 29, Fig. 8, of the sleeve will be presented ;tlush with the surface 24 of the ceiling and allowing for the length of the screwhead 11, which is to enter the flooring above. The connecting-pin 16 is then screwed in the end 18 of sleeve 5 and the parts vertically placed in the opening 22, the screw l1 engaging the floor. The head 11 is then screwed into the floor, as by means of a wrench applied at the lower end 19 of the connectingpin 16. The electric wires 26 and 27 are IOO IIO

then fished along the floorjoist and are drawn down through opening 22 of the ceiling, and ceiling-plate 12 is then screwed to the ceiling by means of screws 28, each of the electric wires passing through separate openings 14. The lower end 29 of the sleeve, Fig. 8, is adapted to rest upon the upper Jface of the ceiling-plate, and it will be understood that by these means the sleeve and engaging pin unitedly operate as a screw, the screwead 1l being embedded in the Hoor and operating as a holding means, the balance of the parts having a length, as above mentioned, equal to the distance from the floor to the plate 12, and it will be noted that plate 12, as well as screw-head 11, operates as a holding means to sustain the weight of a chandelier coming upon the -chandelier-stem 21. Since plate. 12 is provided with numerous screw-holes 13, some of the screws will pass through the body ofthe lath, and the device is considered adequate to resist the weight of a chandelier.

The numeral 30 represents the canopy or ornamental cup fastened to the chandelierstem 21, adjacent to the ceiling-surface 24, by rmeans of the thumb-screw 31, which covers from view the wires 26 and 27 A and plate 12. The wires 26 and 27 pass within stem 21 through apertures 32. The canopy, thumb-screw 31, and chandelier-stem 21 and wires 26 land 27 are not new, and nothing is claimed relative to those parts.

The invention consists of few parts and not expensive in manufacture; but its use results in a considerable saving of time or injury to the upper iioor, and its use in buildings which have been erected or in reconstructing old buildings has proven to be of utility. It will be noted that if pins 6 and 16 were united the invention would be operative in a limited degree. The preferred construction, of course, is to have the construction separate, as shown.

What I claim as my invention is- 1. A chandelier-support comprising a ceiling-plate having a central opening a lengthwise-adjustable engaging pin having a screwhead upon one end, the opposite end of the engaging pin adapted to have a seating upon said cei ing-plate and having an extended part adapted to ass through s'aid central opening of the cei ing-plate.

2. A chandelier-support, in combination, comprising an engaging pin, a sleeve, a ceiling-plate and a connecting-pin; said sleeve adapted to have a seating transversely upon the ceiling-plate; said engaging pin being adjustable within the sleeve and formed at one end as a screw-head; one end of the connecting-pin seated within the sleeve, the opposite end of the connecting-pin being extended beyond the sleeve and beyond the plane of the ceiling-plate.

3. In a chandelier-su port, the combination with a ceiling- plate llaving apertures 13, 14 and 15, of an engaging pin, a sleeve and a connecting-pin; said sleeve adapted to have a seating transversely upon the ceiling-plate said engaging pin being adjustable within thesleeve and'formed at one end as a screwhead one end of the connecting-pin seated within the sleeve, the opposite end of the connecting-pin being extended beyond the sleeve and passing through aperture 15, beyond the plane of the ceiling-plate.

In testimony whereof I have aHixed my signature in presence of two witnesses.

D V CUSHMAN.
