Patented Sept. 9, 1941 LAMP SWITCH OPERATOR Benjamin Schoenberg, Corona, Long Island; N. Y., assignorto Eagle Electric Mfg. Co. Inc., Brooklyn, N. Y., a corporation of New York Original application August 13, 1938, SerialNo. 224,813. Divided and this application October 7 2, 1939', Serial No. 297,420

2 Claims. (01. 240-423) d This invention relates to operators for attachment to lighting fixtures such as ceiling canopies that enclose within them electric switches which are operated by sidewardly extending pull chains usually formed of ball and socket links. This is a division of application Serial No. 224,813, filed August 13, 1938, issued as Patent No. 2,195,582.

It is the principal object of the invention to provide a bracket which has a vertical extension adapted to lie on the outside of an electric lighting canopy near the rim of the canopy and having an aperture adapted to coincide with the aperture usually formed in the side wall of the canopy for the canopy switch operator such as a ball and socket pull chain. Other objects are to provide a simple means whereby the sideward pull on a canopy switch can be made easier and smoother through proper levers, to provide a means whereby the operation of a canopy switch can be made simpler with stops built up and down, so that the ball chain in such a switch cannot be pulled out of the canopy, and to provide a means whereby the operation of a canopy switch is easier and whereby the pull cord actuating such a switch is extended away from the fixture, so that when pulling, it does not interfere with any part of the fixture.

These and many other advantages will be noted from the following description.

Reference is made to the drawing in which,

Fig. 1 is a side View partly in section.

Fig. 2 is an end view, part broken away,

Fig. 3 is a view similar to Fig. 1, but showing an arm of difierent construction.

Fig. 4 is a view similar to Fig. 2 showing the arm illustrated in Fig. 3.

Referring to the drawing, a ceiling canopy has a usual cylindrical rim and in this rim is mounted a transversely extending nipple 33 which is externally screw-threaded. The ball-andsocket pull chain ll of the canopy switch (not shown) extends outwardly through the aperture in the nipple 33. A bracket 3| has a curved vertical extension adapted to overlie the cylindrical rim 30 and has a circular aperture 36 in the extension near the top adapted to surround the nipple 33. A nut is screwed on the nipple 33 and engages the bracket 3| at the right end around the aperture 35 to hold the bracket securely against the outside of the canopy. The nut 35 may extend out over the end of the nipple 33 and provide a stop for the short arm 2| to check upward movement of the angled operating arm. The bracket 3| has a downwardly and outwardly curved portion 32 connected with the botiii tom of the vertical extension, and which may be twisted and continued in an extension 34 sub-' stantially at right-angles to the vertical extens1on.

This lateral extension is provided withan'apep ture for supporting transversely'therein a'pivot pin 3'! which pivotally mounts an angled arm by means of an aperture near the apex of the angle formed by the substantially vertical short arm 2| and the outwardly and upwardly extending longer arm Hi. This angled arm is formed of sheet metal which is substantially right-angled in cross-section excepting a portion near the apex of the angle. At the left end of the long arm in the transverse flange is provided a hole 20 for the insertion of a pull cord 45 which is secured therein by knotting the pull cord at the upper end. The lateral flange 0f the short arm 2! is provided with one or more downwardly and outwardly inclined notches or slots 22 so that the pull chain may be inserted between two adjacent balls and secured on the short arm at any desired position along the chains. The outward extension 34 of the bracket 3| has an inclined edge so that when the arm [9 is in the position shown in Fig. 1, the end of the flange which extends laterally engages the inclined end of the extension 34 at and forms a stop against further upward motion of the arm I9. As shown in the dotted lines, the arm has been pulled downwardly by the cord 45 to the operative position in which the end of the lateral flange of the arm 19 also engages the inclined end of the extension 34 at 86 which provides a stop against downward motion of the arm l9.

Referring to Figs. 3 and 4, a bracket HI has a central aperture H near the top in a curved vertical extension adapted to lie against the rim 30 and to surround the nipple 33. A nut 12 presses the bracket 10 tightly against the canopy 30 and secures it. At the bottom of the vertical extension is a substantially right-angled extension 13 which is centrally slotted and curled at the end to form two bearings 14 for a pin 15 on which is pivoted a rounded angled arm fulcrumed at the apex of the angle having a short vertical arm 16, which terminates in a flat end having a bottleneck slot 18 for engaging between the balls of the pull-chain H, and a longer outwardly and upwardly extending arm 11 which has a flat end apertured to receive the knotted pull cord 45. The fiat end of arm 16 engages the nipple 33 in the inoperative position and i swingable outwardly to the operative position shown in dotted lines in Fig. 3.

It will be understood that pull chain u in either case is retracted by the usual switch spring v (not shown).

adapted to enclose an electric switch mountedwithin it and operable by a sidewardly extending pull chain of the ball-and-socket type extending laterally thru a nipple in the side wall of the canopy, comprising in combination, a bracket, said bracket having a vertical part, an aperture near the top of said part thru which the nipple projects laterally and may be secured thereon and against the outside wall of the canopy by a nut, a lateral extension from the bottom of said vertical member, a transverse pivot pin mounted in said extension, an angle arm mounted on said pivot pin, said arm having a short vertically extending part, said nut extending out over the end of the nipple and forming a stop for the vertical part, means near the top of said vertical part in a straightline thru said apertiu'e for engagement between two adjacent balls of the pull chain, said arm having a longer outwardly extending part, and a pull cord attached at the outer end of said longer part.

2. An operator for attachment to canopies adapted to enclose electric lamp switches mounted within them and operable by sidewardly extending pull chains of the ball-and-socket type, comprising in combination, a bracket, said bracket including a vertical part adapted to overlie the outside wall of the canopy and having a central aperture near the top the walls of which are adapted to surround a hollow protrusion extending laterally in the side of the canopy and thru which the pull chain i passed, an outward extension secured to the bottom of said vertical part and having a pivotal mounting therein, an angle arm pivoted on said pivotal mounting, said arm having a substantially vertical extension, means on said vertical extension for engaging a pull chain, and an outwardly extending part, said outward part having a lateral flange terminating near the apex of the angle and the end of said outward extension forming a stop for engaging the apex end of the lateral flange for limiting the motion of said angled arm on the pivot.
