HANGER FOR ELECTRIC LAMPS.

Specification of Letters Patent.

Application filed October 25, 1910, Serial No. 588,991. Renewed July 12, 1911. Serial No. 638,207.

To all 'wlwm it may concern Be it known that I, ELMER E. SorIEL- LENGER, a citizen of the United States, residing at Riverside, in the county of Riverside and State of California, have invented new and useful Improvements in Hangers for Electric Lamps, of which the following is a specification.

This invention relates to improvements in hangers for electric lamps and analogous devices and has for its object the provision of a hanger adapted to be secured to the lamp cords or conducting wires and provided with means to engage spaced portions of the lamp cords or conducting wires so that when these engaged portions are brought nearer together, as in the act of bending the cord, the distance between the lamp and the surface beneath the same will be increased.

With these and other objects in view, which will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims; it being understood that various changes in the form, proportion, size, and minor details of the device may be made, within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, forming part of the specification :Figure 1 is a side elevation of the device in operative position. Fig. 2 is a detail front elevation of the device with the lamp cords secured thereto, and showing the drums in longitudinal section. Fig. 3 is a vertical section taken on the line 3-3 of Fig. 2 and looking in the direction of the arrow. Fig. 4 is a detail end view of the outer drum also showing the supporting shaft therefor in transverse section. Fig. 5 is a detail front elevation of one of the clips for holding the lamp cords against spreading movement and forming a guide for the adjusting cord. Fig. 6 is a plan view of the same.

Similar numerals of reference are employed to designate corresponding parts throughout.

The conducting wires or as they are commonly termed the lamp cords are designated by the numerals 5 and 6. As usual these members are twisted one around the other. By reference now to the drawings it will be seen that the members 5 and 6 are, adjacent to one end spread apart so as to provide a substantially oval-shaped opening. Further untwisting or spreading of the members 5 and 6 is prevented by means of a pair of clips arranged at the opposite ends of the said oval-shaped opening. Since these clips are identical in structure a detailed description of one will be sufficient :By reference now to the drawings it will be seen that each clip is formed of a single piece of sheet metal and comprises a substantially triangular-shaped shank or body portion designated by the numeral 7. Extending from the narrower end of the body 7 is a relatively narrow tongue 8, and the upper end portion of the body lying on either side of the base of the tongue slants toward the center of the body as shown at 9. By slanting this upper end portion as just described the sharpened corners at the juncture of the slant portions 9 and slant sides of the body 7 will form barbs to embed into the insulations of the lamp cords 5 and 6, when the said body is forced between the cords 5 and 6 at either end of the oval-shaped opening. The tongue 8 terminates in a laterally curved oblong eye 10, and arranged at the base portion of the tongue and at the side thereof opposite to the side over which the eye 10 overhangs is an annulus 11, the function of which will presently appear. The eyes 10 receive the wires or cords 5 and 6 at the opposite ends of the opening, it being understood that each eye is split so that the metal may be curved around the wires 5 and 6. As viewed in the drawings it will be seen that the clips are so positioned that the clip at the lower end of the opening will be positioned oppositely to the clip at the upper end of the opening. It will be further observed that after the clips engage with the wires as just described, the body portions 7 are bent inwardly.

By reference now to the drawings it will be seen that positioned in the oval-shaped opening is a correspondingly shaped frame, the opposite sides of which are designated by the numerals 12 and 13. A supporting shaft is designated by the numeral 14, the major portion of this shaft being circular in cross section, the opposite end portions thereof being non-cylindrical in contour and arranged in correspondingly shaped open- Patented Apr. 23, 1912.

ings at the medial portions of the sides 12 and 13.

What will subsequently be termed an innor drum is shown to include a hollow cylindrical-shaped body designated by the numeral 15, the opposite ends of which are provided with circular heads 16 and 17. The heads 16 and 17 have alining openings for the loose reception of the cylindrical portion of the shaft 14, upon which the drum rotates. The inner drum is somewhat less in length than the length of the shaft, and connection between the latter and drum is established by means of a helical spring 18, one terminal of which is anchored to the shaft, and the opposite end to the body portion 15 of the drum.

What will subsequently be termed an outer drum is shown to include a cylindrical body portion designated by the nu meral 19, the said body portion being provided at its opposite ends with

circular heads

20 and 21, the said heads having central openings for the loose reception of the opposite end portions of the shaft 14, upon which they are rotatably mounted. Surrounding the body portion 15 of the inner drum is a helical spring 22, one terminal of which is anchored or otherwise fixedly secured to one end portion of the body of the drum, while the opposite end portion 19 is correspondingly secured to the body portion 19 of the outer drum. The springs are so positioned that when the drum is rotated in one direction both springs will be tensioned.

By reference now to the drawings it will be seen that the outer drum is somewhat less in length than the shaft 1 1, and the latter at a point between the head 20 and side 12 of the frame is provided with oppositely disposed notches 23. Pivoted at diametrically opposite points on the outer surface of the head 20 are

dogs

24 and 25, the free end portions of which are receivable by the members 23, the structure conforming to that at the one end portion of an ordinary shade roller.

Adjusting cords are designated by the

numerals

26 and 27. These members are directed through the annulus 11, the cord 26 being coiled in one direction around the body portion 19 of the outer drum, and from the middle to one end portion of the said body, while the opposite cord 27 is coiled in the same direction around the body 19 of the drum and extends from the middle portion to the opposite end of the latter. WVith this construction it will be manifest when the outer drum rotates in one direction the

cords

26 and 27 will uncoil from the said drum. The free end portions of the adjusting cords are fixedly secured in any preferred manner to the upper and lower end portions of the lamp cords, it bcing understood when the lamp cords are in normal position the major portions of the adjusting

cords

26 and 27 will be uncoiled from the outer drum. Assuming the parts to be in the last-named positions and it is desired to raise the lamp, the latter is pulled downwardly for a short distance to effect disengagement between one of the dogs and the shaft 14-, this done the downward pressure on the lamp is reduced sufliciently to permit the

springs

18 and 22 to rotate the outer and inner drums. hen the drums are permitted to rotate at a relatively high speed the free ends of the

dogs

21 and 25 will move outwardly by centrifugal. force. As the lamp approaches the required height the pressure is increased to overcome the action of the springs, whereupon the drums will rotate slower in order that one of the dogs may be moved into engagement with one of the notches 23, whereupon further movement of the drums will be prevented and the lamp supported in its adjusted position. and 13 of the frame are provided with a plurality of flexible clips 26, which are bent around the wires 5 and 6 to prevent disen gagement of the frame therefrom.

From the foregoing, it is evident that 1 have provided a device which is comparatively simple in structure and inexpensive to manufacture, embodying few parts and these so arranged that the danger of derangement will be reduced to a minimum.
