To all 'whom t may concern.'

Be it known that JULES D. BIscAri-in'r and FERNAND CAILLETEAU, citizens of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful improvements in Attachments for Operating Snap Switches; and they do hereby declare the following'to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

rlhis invention relates to new and useful improvements in attachments for operating snap switches and consists of a simple and eflicient device of this nature, adapted to be readily attached to the button of the switch and affording means whereby a spring actuated drum, operated by a chain or cord, may cause the button to be turned. rl`he present invention consists of a simple and eflicient device of this nature having various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

The invention is illustrated in the accompanying drawings which, with the letters of reference marked thereon, form a part of this specilication and in which:

Figure l is an end elevation showing the device as applied to the button of a switch.

Fig. 2 is a view in elevation taken in a plane at right angles to Fig. l.

Fig. 3 is a detailed view in elevation, and Fig. 4L is a central sectional view 'through the device as applied to the button.

Reference now being had to the details of the Vdrawings by letter:

A designates a rotatable drum having intersecting transverse slots B formed therein, provided to receive the button A. of the switch.l Said drum has a rib C about the same, the circumference of which rib has ratchet teeth D formed therein and said drum has an annular shoulder E adapted to have abearing in the circular outlined opening E of the diskV F, which disk has laterally extending l. shaped lugs H projecting at points diametrically opposite and which are adapted to engage the slots l formed in the disk I', which latter has a circular outfor the lined` opening through which an annular shoulder at the other end of the drum passes and has a bearing therein. By this construction, it will be noted that both ends ofthe drum have bearings in the disks which are parallel to each other. Said disk l has resilient arms L projecting laterally therefrom and at points diametrically opposite and which are adapted to engage the socket of the lamp on which the device is applied purpose of holding the disks stationary. Y i,

A ring, designated by letter N, has ,an inverted L shaped integral portion N, said ring being mounted about the drum upon which it has a bearing and said inverted L shaped end has pivotally mounted therein a pawl S, adapted to engage the teeth D, and a cord X is connected to one end of said projection N and passes through the aperture in the angled end of an arm I2, which serves as a guide for the cord. A coiled spring, mounted upon the drum, intermediate the disk F and the ring N and has one end fastened to the projection N of the ring and its other angled end J which is fastened to one of the lugs H, as shown in Fig. 4i of the drawings.

It will be noted in Fig. 4: of the drawings, that the spring actuated movement of the ring in one direction is limited by one of the lugs H which is disposed in the path of the projecting portion N.

In operation, when the' parts are assembled, as shown, and the device attached to the socket of a lamp, with the button extending through one of the slots B,by pulling upon the cord, the ring may be given a partial rotary movement and the pawl carried by the ring will engage the teeth upon the circumference of the drum and cause a similar partial rotary movement to be imparted A to the drum, and also to the key of the snap switch, which engages the slot of the drum. ln this movement of the drum the spring will be under tension and when the` cord is released, the spring will return the ring to its normal starting position,carry ing with it the pawl which is mounted thereon, the pawl turning idly over the ratchet having circumferential teeth, disks having .circular outlined openings in Which the ends Y of the drum are ournaled, integral lugs pro-V jecting from one disk and passing through Vapertures in the other disk and clenched ftened at one end to' said projection and its other end to said disk.

2. An attachment for snap switches for operating thesame, comprising a drum having intersecting slots formed therein for the Yreception of a button of a' switch, said drum having circumferential teeth, a flanged disk 1i'z'ivii'i'g circular outlined. openings in Which ones-end of the drum'is journaled, lugs projecting from said flange at points diainetrically opposite, a second disk with circular outlined openings in which the` other end of the drum is journaled, and provided with slots for the reception of said lugs, and iesilient arms for engagement with the socket,

Va ring journaled upon the drum and having a lateral projection, a cord secured thereto,

a paWl pivotally mounted upon said projection and engaging said ratchet teeth, one of said lugs being positioned in the path of said projection, a spring fastened at one end to the latter and theother end to one of said disks, as set forth.
