e citizen of the United States, residing et Schenectady, county of Schenectady, State of New York, have invented certain new und useful Improvements in Fixture-Switches, of which the following:` is it specification.

My invention relates to electric switches adapted particularly for use in connection With fixtures for incandescent lightin in which it is desirable to have the switc located at some point in the fixture instead of in the lamp-socket.

The object of my invention is to provide a strong compiuti switch which miiy be cheeplf,r manufactured and adapted for use in substani lolly the seine mennen es the cock ofthe oriilinmy gns-iixture.

The invention will be more reediljY under4 stood by reference to the acpompenying drowiuvs, for mineT :t port of this specifics-tion, in whiiA Figure 1 is :i vertical lonfritui'linel section of e switch '.fiiihodying one tlorin of my invention, und Fig. 2 e horizontal longitudinal section 01"' the Sonie.

As shown iii the drawings, the switch is niouiii, il in zi ring-ironie l, havin tin-ended sleeve projections :it oppositceni'ls or etteclk inem with tho ,i-iiiiury piping of the iixtiue und'through which the conductor-wires are led` and :in operi in one side for the pessage ol the sufiic eus, sud surroiiiiiling the ironie 'l e prfwsoiluoetul shell 3, Consisting of two heniispherical pu its, one oi which muy be provided with e hoed. sioni' its odg-o and the other with en outturnci! lionne or sioiiller bead adapted to lic spriinr into the bend of the other part.

W'ithiii the ring-ironie 1 and et the side f-plesite the aperture ZZ an inhibiting heise lolock 4 is secured. by ineens o1 e crew 5, extending therethrough und engen-ing e topped hole in the freine. Extending; across the up- `per surface of the buse -1- .and Yneer isrespective ends are two metal contacts sind 7, each having one cud 8 bent down et right iin-- gies and engaging a side of the base end secured in place by e screw 9, passing transversely through the base and enveging :i tapped hole 1n the Contact. Esc-ii of thev bent-doWn-ends 8 carries a` binding-screw iii,

whereby the ends of the line-wire A n i be connected to the switch.

On each side of the frame 1 is placed a disk or cup-sheped piece 11 of sheet insulation adapted toclose the ends of the chamber o the rin -frame and prevent any projectingr end of he conductor from coming in contact with the shell 3. One of the pieces 1l of insulation is provided with two diemeti'icelly-- located notches 12, through which the continuous conductor B is led out between the outside of the piece 11 and the inclosing shell 3,

and thereby held out ofthe Way of the switch parte in the main chamber.

The operative ports of the switch com rise e plain spindle 13, provided with a han e or thumb-piece 14 extending through hole 2 and the main chamber of the frame into a recess 15 in the base-block 4 and rests at its lower end upon the head of the screw 5. A transverse pin 16 is secured in the spindle 13 just inside of the frame' l, which serves to hold the spindle from moving endwse, and just below the pin 16 is e second in 17. Surrounding the spindle 13, just be 0W in 17, is afcempiece 18, consisting of a mete uncl'ng bent into M shape end rovided with e notch 19 in each end adepte to receive n guide-pin 20, secured in the upper part of frame 1, and in the two uppermost bends 21 are transverse depressions 22. Mounted loosely on the spindle 123, just below the carn-piece 18, is an M-shit ed sprin i 33, mede from sheet metal en d n( apte( to e pressed upon by the lower bend 24 of plie canipiece 18. Resting in the recess 15 in the basefhlock 4 and surrounding the lower end of spindle 13 is n helical spring 35. 'Loosilv surrounding the spindle 13 is a. disk .t'i ot' insuletiomwhich rests upon the upper end of helical spring 25 and is pressed down upon by the ends of the M-shaped spring 23. To the lower side ol disk 26 is sea-izzsd a metallic ring 27, which constitutes the n'iovnlile Contact.

When the spindle stands in the position sho-en in li`ig.1,witl1 vthe in 17 resting in the slight depressions 22 of t e highest portions ci' the cem-piece 18 the several movable parte mounted upon the spindle 13 are crowded into their lowermost position e einst the tension of the helical spring 25 an with the contact-ring 27 in engagement with both stationery-contncts and 7. Yhen the spindle is turned through an anle of ninety degrees the pin 17 will permit t e cam-piece 18 an the other mornble parts to rise under the IOC pressure of the helical spring 25 until the lowermost bend 24 of the eem-piece 18 enga res the pin 17, therebv breaking the contact )etwelen ring 27 und the stationery contacts mn 7.

It is to be noted that in my deviee the switeh-spindle muy be turned in either direc-- tion to operate the switch, that the ports are so constructed that they may be cheaply mede end easily assembled, and that interference with the conductors is avoided in the i operation of the switch.

What I elnim es new, and desire to secure by Letters Patent of the United States, is-

1. The combination of e eireulur freine, e segmental base secured therein, metal eontaets mounted on Suid base., en actuatingspindle journaled in seid frame dimnetricully opposite said base und provided with a side projection, an insulating-disk journnled upon said spindle and provided with a bridging contact, a helical spring surrounding seid spindle below seid disk and normally noting to force the bridging Contact out of engage"- ment with the stationary contarte, er leefs )ring snrronmlingf` seid spindle above' seid i isk, and an M-Hheped eem member snrronnding Suid s )indle between sind side projection und said leef-s )ring und engaging et its ends with the seid mme. i i

2. 'lhe combination of inlopen-Sided frame for an eleetrie switeh, and n disk adapted to close one of said open sides end provided with reeesses to permit the passa fe of e con dnetor-wire from the insdeof the vrame along the outside of the disk and beek into the interior of the frame.

In witness whereof I have hereunto set my hund this 24th, day of November, 1902.
