.of an electric switch adapted to be incorporated in an electrolier or the like. The object of thus combining in the electrolier structure the switch, whereby the lamp supported by such structure is con trolled, is to overcome the disadvantages more fully ointed out later resident in the provision of switches for controlling such lamps at stations removed therefrom. At the same time, it will be seen that I preserve the'neat and artistic effect desired in such electroliers.

To the accomplishment of these and related ends said lnvention consists of means hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detailcertain means embodying the invention, such disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings: Figure 1 represents in side elevation an electrolier supporting a well known type of are electric lamp l1'1,'Wl1lCh electrolier has been incorporated my improved type of switch; Figs. 2- and 3 are inside views of the switch structure by itself in its disassembled condition; and Fig. 4 is a side elevation illustrating a modified form of the invention.

Referring first of all to the switch construction shown in Fi s. 2 and 3 it may be stated that the speci 0 type of switch A. em loyed is the ordinary one with a rotatab e button a" that is adapted in successive rotative positions to alternately make and break the connection between the conductor terminals. Such rotatable switch I propose to o erate by means of a pawl and ratchet.

mec anism A shown in' the second of the two figures named. Such pawl and ratchet mechanism is in turn operated by means of a cord, or preferably a fine chain A", bythe pulling of which a definite amount of rotation is imparted to the switch such as is adapted alternately to effect the desired electrical connection and to thereupon break the connection thus made. This switch and switch controlling mechanism I incorporate in the electrolier structure as follows: It is quite general to suspend the electric lamp, whether a cluster of incandescent bulbs or a single arc lamp, as illustrated by means of a hollow tube B extending downwardly from the ceiling of the room, wherever such light is to be used. Such tube -B may be secured in any'approved fashion to the ceiling, there? being usually provided an inverted cap 72 that conceals the manner of attachment as well as the lead wires to the lamp. Such wires are then carried down to the lamp B within hollow tube 13 and are connected'to the pro er terminals on the case of the lamp in the fiishion shown in Fig. 1. As an ornamental feature for breakin the continuity of the rod or tube thus uti ized to support the lamp a ball B is very frequently used, such ball usuallyfitting over the tube and being secured by suitable means thereon intermediate of its ends.

transform into a casing to receive the switch mechanism which has been above recently described. Instead, however, of sliding the ball onto a continuous tube I make the tube into two sections and insert theball there between, makingthe latter of two separable portions, one of which I) bears the necessary bosses to which are fitted the ends of the tube sections; the other of WlllCll b is attached to the portion thus fixed in the electrolier structure. Firmly mounted in such fixed portion b of the ball 038M121 is the It is this ball that I aforesaid rotatable switch device A, to the terminals of which are joined the respective ends of one of the wire conductors b b, passing down through thetube 1n the man ner above described, such wire being severed for this purpose. In the other or. detachable portion b of the ball, I mount the ratchet device A for rotating or actuating such switch.

Ratchet device A is quite simple in construction comprising two members a a 1'0- tatably mounted within ball port1on b. Of said members the innermost a is a disklike ratchet wheel, adapted in the assembled condition of the casing to operatively engage the button of the rotatable switch by virtue of projections or lugs a on its inner face disposed so as to fit on either side of such button. These lugs are conveniently provided by simply striking up portions of the disk forming the wheel. The other a of said members bears a pawl a that is adapted to engage ratchet wheel a to rotate the same. limit the movement ofsaid awl-bea'ring member in either direction. peripheral flange a on such second member serves the double function of engaging stop a 'to thus limit the members rotation and to retain in place a cord or preferably a light chain, one end of which is secured to. said periphery, the other of which extends downwardly into convenient reach of persons who may desire to operate the switch. A spiral spring a", located behind member a, is adapted to normally retain one end of flange a against stop a, the point of attachment of the cord to member a being such as to cause the rotation efiected thereby to be against sprin af. The relative disposition of stop a; an

the length of flange (1 is so gaged as to permit the rotation of member a through the proper angle to give the rotatable switch the particular turn requisite to effect its operation, either to break or make the circuit which'it controls. g

In the assembled condition of the'parts just described, (Figs'2 and 3,) the detachable portion of the break ball that bears the switch actuating mechanism last set up, is placed face down upon the fixed ortion of such ball. In this position the ugs a projecting from the exposed face of ratchet wheel a, fit on either side of the button of the switch so that rotation of the former effects concomitant rotation of the latter. A suitable aperture is left in the edge of the detachable ball portion a to permit the free passage therethrough of chain A which atter is accordingly allowed to depend, as already set forth, into reach of the operator. Assuming the switch now in the assembled "condition of the parts, just described, to be in its ofl position, if the chain be thereupon pulled'the ratchet wheel will be partially rotated until pawl bearing member is brought against stop a and a-corresponding rotatlve' movement will be given the button of the switch whereby the electric circuit is closedand the lamp lighted. A second pull of the cord effects a second similar rotation with the eflect of breaking the connection and such. operation may be performed in succession as often as may be desired.'

It will of coursebeunderstood that the use of my improvement is not limited to electroliers, it being immaterial whether a lamp, or other translating device as for A stop a is provided, adapted to aaaeao example an electric fan be supported from tube B. Andfor that matter where a cable is utilized as the supporting means instead of a tube, I still can conveniently interpose a ball casing corresponding to break ball B to house the switch and switch actuating mechanism, see Fig. 4:.

Other modes of applying the principle of my invention may be employed instead of the one explained, change bein made as regards the mechanism herein disclosed, provided the means stated by any one of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out-and distinctly claim as my invention 1. The combination with a translating device; of a hollow casing made up of two separable sections, one of said sections being provided at one end with means for attaching it to a support, and at the other,'with means for attaching such translating device thereto; means mounted within the same casing section for controlling the circuit of said translating device; and pendent means for actuatin said controlling means mounted within t e other section and separable therewith from said first section.

. 2. The combination with a translating de vice; of a hollow casing-made up of two separable sections; a tube attached to one end of one of said sections and adapted to be attached to a support; a second tube attached to the other end of said section and adapted to support such translating device; means mounted within the same casing section for controlling the circuit of said translating device; and pendent means for actuating said controlling means mounted within the other section and separable therewith from said first section.

, 3. The combination with a translating device; "of a' support for suspending said de- I vice from the ceiling; a hollow oasmg breaking said support intermediately between its en s; said casing being made up of two sections, one fixed to said support, the other separable therefrom; means mounted within said fixed section for controlling the circuit of said translating device; and pendent means for actuating said controlling means.

mounted within the other section and separable therewith from said first section.

4. In an electrolier, the combination of a tube for supporting the lamp and carrying the wires thereto; a hollow casing breaking said tube intermediately ofits ends and comprising two portions, one separable from the other; a rotatable'switch mounted in the fixed portion of said casing for controlling the circuit through said wires; two rotatable members mounted in the other of said portions, one of said members being a ratchet Wheel adapted on rotation in the assembled condition of said casing to operate said controlling device; a pawl borne by the other of said members and adapted to engage said ratchet wheel; stops adapted to limit the movement of said pawl-bearing member; a spring normally retaining said pawl-bearing member against one of saidstops; and a cord for moving said member from such normal position. I
