Speciflcaton ot Letters Patent.
Patented Sept. 15, 1908.
Application fllad lay 29, 1908. Serial No. &86,736.
To all 'whom it may concem:
Be it known that I, EDsoN B. WLcox, a citizen of the United States, residing at Meriden, in the county of New Haven and State of Conecticut, have invented certain new and useful Im 'ovenents in Electrical'Fittings, of which t e following is a specification.
My invention relates-to improvements in electric fittings.
I have illustrated it as embodied in a rosette or connection box.
It has been customary to tie 'a knot in the conducting cord inside a rosette 'so as to dispense with any Stress upon the terminals.
his is likely to cause a short circuit and sometimes the knot pulls through. It has also been proposed to twist the conductor or conduct'ors about some projection on the eX- terior of the rosette or to pass the conductors through tortuous passages. These .devices are either expensive to manufacture or else difficult to install. v
It is my object to construct a simple, chea device and which can be readily installe without danger of injury to the conductors.
Figure 1, is a vertical section of a fitting embodying my invention attached to a ceiling block. Fg. 2, is a plan View of the fitting. 3, is a bottom view. Fi 4, is a section on the plane of the line X- F' 3. Fig. 5, is a section on the plane of the e Y-Y F ig. 3.
The block 1, is secured to the ceiling 2, in any suitable manner. The main circuit terminals 3 and 4 aresuitably secured to block 1.
The rosette body 5, is preferably made of porcelain in one iece and is removably secured to the ceilng block by the terminals 6 and 7. The flange or wall 8 forms an interior chamber sufficiently large to accommodate the wires, screws etc. The terminals 6 and 7 are secured on the floor 9 of this chamber and eXtend through notches 10 and 11 in the wall or flange 8. i
The body is formed with a number of intersecting straight channels and passages for receiving the conducting wires. From the central passage 12 branches the small interior channel 13 which meets the passage 14. The exterior channel 15 extends from passage 14 to passage 16. Channel 17, passage 18, channe 19 and passage 20 correspond with channel 13, passage 14, channel 15 and passage 16 on the opposite side. These pas-' sages and channels are of such a nature that they may be readily formed in the ordinary process of casting or molding. The wires 21 and 22 which are custonarily insulated are drawn through the passages just described able to the use of separate terminals since it absolutely prevents mistakes in connecting up the wres and insures uniformty in arrangement I prefer to form a rather long neck or 'collar 25 on the body so as to prolong the central passage 12. This prevents displacement of the wires and rotects them. It also acts as a sort 'of guar to the parts of the conductors located in the exposed channels 15 and 19.
The proportions shown are referredbut I wish it understood that each c aim is limited only by its own terms and as set forth in the specification.
Obviously any device may be Suspended from the wire 21 and 22, for instance a lam So also it is obvious that the fitting may itse be inverted and supported by the wires. The design of the fitting will be modified to suit the particular req uirements of its use. The sha e of the termnals is also unimportant an will depend upon the circumstances of'individual cases.
What I claim is 1. An electrical fitting comprising an inte- %lal body of insulating material and having a ange forming an interior chamber, terminals secured to the body within said chamber, said body also having `a main vertical passage, two pairs of vertical passages and two exterior Channels, each channel connecting the outer ends of the passages of one of the pairs of passages.
2. An electrical fitting comprising an inte-- gral body having a lateral flange and a cen- 2 &98,540
