INCANDESCENT-LIGHT HANGER.
Specification of Letters Patent.
Patented Feb. 13, 1906.
Application filed March 6, 1905. Serial No. 248,662.
To aZZ whom it may concern:
Be it known that 1, ROBERT D. McIN'rYRE, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented a new and useful Incandescent-Light Hanger, of which the following is a specification. I
This invention relates to hangers of that general type employed for the support of adj ustable incandescent lamps. The principal object of the invention is to provide a novel form of hanger in which the height of the lamp may be readily adjusted and to provide a construction in which the lamp may be automatically locked or held in any position to which it may be moved.
A further object of the invention is to provide a simple and inexpensive form of hanger which will be retained in a position adjacent to the ceiling or other support and to provide novel means for establishing a lamp-circuit so that such circuit may be held closed without regard to the position to which the lamp is adjusted.
A still further object of the invention is to provide a novel form of adjustable hanger in which the parts are arranged in a sectional casing so constructed that they may be readily separated and the various parts examined and repaired at comparatively small expense.
With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificingany of the advantages of the invention.
In the accompanying drawings, Figure 1 is an elevation of an adjustable lamp-hanger constructed in accordance with the invention. Fig. 2 is a vertical sectional View of the same drawn to an enlarged scale. Fig. 3 is a similar view, the section being taken on a plane indicated by the line 3 3 of Fig. 2.
Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.
The casing is formed of two semi-ovate sections 10 and 11, provided with interfitting annular flanges 12. These sections are held together by suitable spring-catches 14, having openings for engaging pins or lugs 15, proj ecting from straps or other supports 16, the straps being secured to one of the sectlons, while the catches are secured to the other.
Extending around the upper section 10 1s a metallic loo or strap 17, at the central upperportion of which is an eye 18 for the re ception of a bracket 19 or other supporting device secured to the ceiling. The lower ends of the strap or elbow project beyond the lower edge of the section 10 and terminate in fingerpieces 20, by which they may be sprung outward when-necessary, near the ends of the loop for openings for the reception of aspmdle 21, one end of the latter being of rectangular or other non-circular form, and the opening which receives it being of similar contour in order to hold the spindle stationary.
On the spindle is mounted a winding-drum 22, that is connected to the spindle by means of a suitable spring, and the drum carries pawls 24, arranged to engage in openings or recesses formed in a disk 25, carried by the spindle, the construction of this part of the mechanism being somewhat similar to that employed on shad e-rollers in commercial use.
The periphery of the drum is covered by a sleeve 30, formed of insulating material, and near each end of the drum is an annular flange 32, formed of some good conducting material, the flanges projecting from rings 33, that are secured to the drum, and each of said rings is provided with a projecting arm 34, having an opening for the reception of one of the wires 35, leading to the lamp 36. The wires are insulated and twisted together in the usual manner and pass through an insulating-sleeve 37, formed on the bottom of the section 11 of the casing.
The edge portions of the two sections of the casing are provided with recesses 40 for the reception of the ends of the windingdrum; but this in all cases will not be necessary, inasmuch as the drum may be made of a length shorter than the internal diameter of the casing.
Secured within the upper section 10 of the casing are conducting-strips 42, preferably formed of spring metal, and the free ends of said strips tend to move outward into contact with the outer faces of the flanges 32. The ends of these strips are provided with brushes 44, which may be formed of any suitable material, and these by engagement with the metallic flanges complete the circuit to the Wires wound upon the drum. The upper ends of the strips 42 are connected to mainline wires 45, that are connected to a suitable source of energy.
When the lamp is to be adjusted, it is merely necessary to pull the same down by grasping either the lamp or the cord. This movement turns the drum and winds the spring until the desired adjustment has been accomplished, and one or other of the pawls will engage in one of the locking-recesses and the lamp will be held in the position to which it has been moved. When the lamp is to be elevated, it is merely necessary to pull down on the cord to an extent sufficient to release the locking-pawl and allow the spring to un- Wind and revolve the drum in the opposite direction. Should repairs be necessary, the lower section of the casing may be detached by pulling outward on the catches 14, and then by pulling outward on one or other of the finger-pieces 22 the drum may be readily removed, if desired.
Having thus described the invention, what is claimed is 1. In a device of the class specified, a casing formed of upper and lower sections, means for connecting the sections to each other, spring-arms carried by the upper section at points outside the section and having spindle-receiving openings, a spring Windin drum having a spindle extending throu said opening, collecting-rings carried by the drum, conductors arranged within the upper section, brushes extending therefrom and engaging the clamping-rin s, and lamp-supporting wires wound on t e drum and electrically connected to the collectin -ring.
2. In a device of the class speci ed, a twopart shell or casing, each member having an insulating-collar or the passage of current conducting wires, spring-catches for holding the two members of the casing together, a spring-strip extending over the upperpart of the casing and fOIIIllHg at its upper end a hanger or support, the lower portion of the strip being provided with spindle-receiving openings, a winding-drum having a spindle extending through said openings and provided with an insulating-cover, collectingrings carried by the winding-drum, currentconductors arranged within the upper portion of the casing and connected to the leading-in wires, brushes carried by the currentconductors and engaging the current-collecting rings, current-conducting Wires passing out through the insulating-collar of the lower part of the casing and forming a lamp-support, the upper ends of said wires being Wound upon the drum and connected to the collecting-rings, and a spring for winding said drum.
In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.
