ELECTRIC-LIGHTING FIXTURE.

Specification o! Letters Patent.

Patented Mar. 25, 1919.

Application lled February 23, 1918. Serial No. 218.707.

To all whom it may concern.' i

13e it known that I MAX Hnasxovrrz, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Electric-Lighting Fixtures, of which the following' is declared to be a full, clear, and exact description. This invention relates to electric lighting fixtures, and its primary object is to rovide means (as a component part of the flixture) for securing a pull switch at some point in the xture, intermediate its point of suspension and the lamp socket. Theres are may instances where no wall switch is provided for turning the electric light on and ofi', and the switches at the lamp sockets are the only means in the lamp supporting parts of the fixture for turning the light on and off. In the resent lighting fixture, a single lamp or c uster of lamps may be used on a lighting fixture, and all controlled from a single switch located in the support for the lamp or lamps, at some place intermediate its point of suspension and the lamp sockets. Another object is to i rovide an electric switch holding cage which may be installed in practically an of the well known forms of endent lighting fixtures. Other objects and) advantages will occur in the course of this specification and with all of said ob jects and advantages in view, this invention consists in means for securing an exposed electric.- light switch of the pull type in a pendent lighting fixture intermediate its point of suspension and the lamp socket. The invention further consists in the several novel features hereinafter fully set forth and claimed.

The invention is clearly illustrated in the drawings accompanying this specification in which Fi re 1, is a side elevation of an electric lighting fixture embodyin a simple form of the present invention; ig. 2, is a deta-il side elevation of the switch containing member and the adjacent supporting members of a fixture, showing a switch secured in the switch containing member; Fig. `3, is a view partly in plan and partly a horizontal section of the parts seen inFig. 2., theJ line of section being indicated at 3--3 in Fig. 2; Fig. 4, is a detail side View of the parts seen in Fig. 2,partly in verticalcross section, the line of section bein indicated at in Fig. 2; Fig. 5. is a etail side elevation of a slightly modified form of the'fixture, partly broken away; Fig. is a detail side elevation of a second modification of the fixture partly broken away, and Fig. 7, is a detail plan of the switch4 containing meniberseen in Fig. 6.

Referring to said drawings and first to Figs. 1 to 4 inclusive, the reference character 10, designates a pendent stem which is sustained from the ceiling by any of the well known forms of connection, and its uper end is covered with the usual canopy 11.

elow the pendent stem 10, is illustrated a chain type of lamp support 12, to the lower end of which is attached a shade holder 13, of any well known form of construction in which is contained an ordinary lamp socket for an electric light bulb. A shade or globe 14, of any desired type may be secured to the shade holder in any suitable manner as is well known. The member 10, may be regarded as the upper supporting member of the fixture and the member 12, may be regarded as the lower .supporting nmember thereof, and between said upper and lower supporting members is interposed a switch containing member 15, which is secured to said upper and lower supporting members to form a connection therebetween, and to support the switch 16, which controls the electric lamp of the fixture. Said switch .may be any of the well known forms of pull switches which are operated by pulling upon a cord or chain, and in the form illustrated, the cord 17, extends to a convenient place where it may be grasped by a person operating the switch. In the form of switch shown t e cord is connectedat its upper end with a bell crank lever 18, fulcrumed upon an outstanding arm 19, of the switch and connected to a contact actuating member of the switch by a chain 20. Downward pull upon the cord 17. causes an outward pull upon the chain 20, which, in accordance with this type of switch, alternately makes and breaks contact 4between the contact members. No claim is made to this form of switch but itis chosen for the purposes of illustration. The conductor cords 16, run to the switch and from the switch to the lamp socket. It will be observed that the fixture can be wired without taking it apart.

In the form of switch containing member seen in Figs. 1 to 4 inclusive, it is made of two attachable and detachable members 21,

22, between which the electric switch is held. The part 22, comprisesl an upright loop like portion Q3, the two sides of which are co iinected by a plurality of transverse semi circular bands 24. The upper end of the loop 23, is shown as formed with an internally threaded socket 25, into which is screwed the pendent stem 10. To the lower end of loop 23, is attached the uppermost link 12, of the chain 12. The member 2l, comprises two companion seiiiicircular bauds 24, which are connected by upright spacing bars 26, 27, held against the upright members of' the loop 23, by suitable means, here shown as comprising a curved lug 28, formed on the upright bar 26, which enters a hole in a lug 29, formed on the loop :23. The other upright bars of the members '21. :22, are formed with Semicircular, companion lugs 30, 31, which have semicircular, opposing recesses on their meeting faces to receive the stem 19, of the electric switch. Said semicircular lugs 30, 31. are externally screw threaded and are secured together by an internally screw threaded ring y.32, which is screwed upon the externally threaded portion of the lugs 30, 31. The switch is placed in the switch containing member 15, by first iinscrewing the ring 32, from the lugs 30, 31, and spreading the. two members 21, 22, apart. as shown on dotted lines in Fig. 3, after which the switch is inserted between said members and the two brought together with the semicircular lugs 30. 31, clasped around the stem 19, after which the ring 32, is screwed upon said lugs.

In the torm shown in Fig. 5, the loop '23, of the member '22. is formed at the top and bottom with sockets '25. for the reception of upper and lower tubular supporting members 10, ot' the lighting fixture. This form may be used in ,lighting fixtures having the common and well known tubular stem for the lamp or lamps. In other respects the switch supporting members may be constructed in accordance with the preferred form shown in Figs. 1 to 4 inclusive.

In the form illustrated in Figs. 6 and 7, the loop 225". of the member 2'2". is attached at its top and bottoni to adjacent links 12, of a cham fixture. This type of' switch supporting member acts as a link in the chain and may be interposed at any point intermediate the ends of a chain type fixture. In the form illustrated in Figs. 6 and 7, the members 21", and 22". may be secured together by screws 28", passing through the adjacent vertical portions of said members, as is clearly illustrated in the drawing. In other respects the construction of said members 21, 2'2", may be the same as that illustrated in the preferred form of the invention.

From the above it is readily apparent that a pull switch may be interposed at any point in a pendent lighting fixture between the point from which it is sustained and the lamp socket or sockets, which switch may be operated by a cord, chain or the like extendingdown to within convenient reach whereby a single lamp or cluster o-f lamps supported by the fixture, may be controlled from one switch interposed in the fixture itself.

More or less variation of the exact details of construction is )ossible without departing from the'spirit oi this invention; I desire, therefore, not to limit myself to the exact forni of the construction shown and described, but intend in the followinnr claims to point out all of the invention disclosed herein.

I claim as new, and desire to secure by Letters Patent:
