ELECTRICAL ROSETTE.

Specieation of Letters Patent.

Patented April 9, 1907.

To all whom it may con/cern;I

Be it known that I, GEORGE B. THOMAS, a citizen of the United States of America, residing in the city of Bridgeport, county of Fairfield, State of Connecticut, have invented an Improved Electrical Rosette, of which the following is a specification.

The object of my invention is to reduce an electrical rosette whichcan be easily manufactured in -one piece, which can be easily Wired when in use, and which will efiicientl hold the wires when connected up.

In the accompanying drawings, Figure 1 is a vertical section lof an electrical rosette constructed in accordance with my invention and showing the Wires being inserted. Fig. 2 is a corresponding face view. Fig. 3 is a vertical section after the wires have been knotted and connected up. Fig. 4 'isa side elevation. Fig. 5 is an elevation lookin at the Fig. 6 is an elevation ooking at the opposite side; and Fig. 7 is a sectional view on the line 7 7, Fig. 5.

I prefer to mold the body of the rosette out of porcelain or the like insulating material and in one piece with a central knob A and a flanged base B. In the fianges are formed holes t for the screws to secure the rosette' to theceiling, molding, or the like. I prefer to torn' at opposite sides of the rosette lugs b 1)','in which are secured the brass or other .netfilic terminal plates D, with their bind- These plates are preferably of the L-shaped form shown in lugs. 2 and 7 and on the inner ends carry binding-screws d to receive the bared ends of the rosetteor drop-wires E E. y

The central knob A has a vcentral vertical hole a, connecting with a lateral hole or outlet al', leading to the outside immediately under the flanged base ofthe rosette and about midway between the terminal plates D, and there at the mouth of this hole c the knob has a transverse open notch C formed in it to afford a chamber for the knot of the wires and to leave open lateral grooves c c for the wire ends to the terminal Aplates D.

In the side of the knob between terminal plates D and. o posite that where the Wires out knotted and connected to the terminal plates there is .formed a radial slot F from the central hole a and cut back a sufficient distance to permit the ends of the .wires to be easily inserted in the first place through the lateral hole a', as shown in Fig. 1. For this ur ose it is best to cut the slot F in the kno a the way back to the base B as shown, so that practically a straight passage is offered for the lateral insertion of the wlres throu h the knob. This straight Cross-passage a so facilitatesthe manufacture of the rosette. After insertion, as

shown in Figs. 1 and 2, and `after knotting of the wires and the connection of the bared ends to the terminal plates the covered art of the wire for the pendant may be pu ed down into the central hole a, as shown m Figs. 3 `to 7. I prefer to form that part of the slot F where it opens into the` hole" a somewhatnarrower, as at f, than the diam eter of the hole a, Fig. 2 and narrower than the normal diameter of" the covered wires usually used, so that the covered wires have to be squeezed through into the hole a, when they are turned. down from the position Fig. 1 to that shown in Fig. 3, and consequently the wires will hang central in the hole a against ordinary side strain,I which might otherwise tend to pull them out into the slot F.

My described construction of rosette is specially intended for use as a simple fuseless rosette, and it has the ladvantage over such rosettes as heretofore constructed that it` between the terminalplates, as and for the4 purpose described.

2. A rosette, having a base and a knob with a central hole, terminal plates, a lateral outlet from the central hole for-the Wire ends name to this specification in the presence of tcl) the sicl of the knoluheltween1 the erniinal two subscribing Witnesses.

the rosette, between the terminal plates. G. W. lGOODRIDGTE,

In testimony whereof I have signed my F. E. SEELEY.
