DONALD A. ROSE, BERKELEY, CAL'EORNA.

FIXTURE DEVICE.

Application filed March 1.1, 1922. Serial No. 541,10?.

To all 107mm 'it may concern Y lle it knownv that l, DONALD Rose. a. citizen ot the llnited States, residing v, in the county ci llanieda anll titate 'ot California, have. invented new and useful Improvements in Fixture Devices, oi' which the following is a speciiication.

rlhis invent-ion relates to improvements in chandelier attachingv devices.

rllhe principal object ot this invention is to provide simple means for attachiing` a. chandelier to an ordinary outlet commonly employed in electric wiring.

vAnother object ot this invention is to .produce a device which may be applied to installations now installed without involving` a considerable outlay.

A further object oit this invention is to produce a device oi' the character described wherein the electric light iixture be easily removed as tor replacement or tor rewirinfr.

A `further object of this invention is to produce a device wherein the wires projecting` trom the outlet will be securely attached as to binding posts, thereby eliminatingthe possibility of a short circuit, as is common with outlets where the wires are allowed to dangle after the fixture is removed.

Other objects and advantages will be apparent during,` the course ot the following description.

ln the accoinpanying` drawings forming av part ol this specification and in which like numerals are employed. lo designate like parts throughout the same,

Fig. 1 is a cross section taken on the line l-l of Figure 9J,

FigA 2 is a top plan view ot an outlet with part oi my device applied thereto,

Fig. 8 is a top plan view oi' my complete device,

Fig. 41 is a detail cross sectional view taken on the line ot Figure 2,

Fig. 5 is an enlarged det-ail cross-section showing' the contacts,

Fig. 6 is a perspective detaily view ot one oll the contacts, and

llig. 7 is a perspective view oi the contact carried upon the outer portion ot my device.

ln the wiringof a building, it is usual to place a metal outlet box upon the wall at a point where the fixture is to be attached. The electric wires leading to the outlet bei; are either led thereinto through a metal conduit through the center or through. openings provided other points. lt is to thisy outlet bon that l propose to attachniy invention, thereby forming a means for attach ing' the tree ends ot the wires enteringl there in, which are now commonly left free.

ln the accompanying drawings wherein for the purpose of illustration is shown a preferred.embodiment ot my invention, the numeral 5 designates a portion of the wall which may be either side wall or a ceiling. while the numeral 6 designates the usual metallic outlet box. rThis outlet box is provided with openings 7 and 8. through which the wires enter. lt is understood, however, that these wires mioht enter through the opening 9, the result being; the same.

At 11 ll. have shown a block ot a contour corresponding with that ot the outlet box. This block is preferably formed ot insulating material.

Openings

12, 18 and 14 are formed in this block and are adapted to reoister with the openings 7, 8 and 9, while lugs 16 and 17 are secured to the outlet box 6 at points diametrically opposite each other, and are each provided with set screws, as shown at 18 and 19. These set screws are adapted to enter openings 20, as is best shown in Figure l formed in ledges 21 recessed in the sides ot the member 11. The member 11 is entirely cut away at 22 and 23. so that it may be removed when the set screws 18 and 19 are withdrawn from the openings 20.

Contacts 24: and 25 are secured to the member 11 as by

screws

26 and 27.

Binding' posts 28 and 29 are secured in each of the contacts and serve as a means for attaching electric wires entering the outlet box. At 81 l have shown a cap, which is adapted to contact the wall 5 and to entirely cover the outlet boX 6. This cap is provided with a metallic bushing 32, which is threaded for the reception of the ordinary i'iXture. This bushing is retained in the cap as by screws 88 and 84.

Contacts are provided upon the cap 81 the same being two in number, and are of the construction best shown in Figure 5, wherein the numeral 86 represents a contact bent upon itself' and reta-ined in the cap 86 as by a screw 87.

' Each one of these contacts carries a binding post 88, to which the electric wire entering;` the fixture is attached.

ln use, myy device operates as follows Member 1l is inserted in the outlet box by passing the lugs 1 6 and i? through the cutthe outlet are secured to the bindin@ "este 28 and 29. The electric fixture ie new secured in. the bushing` 82 and the free ends or the Wires extending therefrom are secured te the binding); posts 38 carried upen the cen- Ytenets 36. The iiiture, with the cap attached thereto, is next placed the outlet bof; end screws, such as shown in dotted line at 30, are passed through the cap 3l and into the member ll, which, :is beiore nientiied,y is made of en insulating iiiztt'erial, preiertblj7 porcelain.

The assembly is rsuch that the contacts 36 will vContact with the contcts 24 and 25, the result being` that current will be established from thesource through my device and into the fixture.

It is to be understood that the form of my "'bed is to be taken as t preferred exenipA ot the serie, end that various changes in the shape, size and arrangement of parts ine), Y resorted to Without departing from the Spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, l claim t Y K ln et device of the character described, the combination olf an outlet box, luge 'ornied on the sides of seid outlet bof;yq insulating member h airing cut-wir/1.,v portions 0n the periphery thereof, ledges formed on seid insulating ineinber, eid 'insulating :member being provided With opeoir therethrough, contacts Secured on the e A fece oi seid insulating member,r u f i adapted to overlic seid outlet box and l insideting ineniber, a bushing' carried by seid cup, seid bushing' being' adapted to receive a light fixture, and contacts cmfried on seid cap und adapted to engage sein. first vmeritioued contacte.
