SWITCH .aim courrier: iviEcHANisM FOR ELECTRIO-CURRENT-REGULATING PLUGS AND sOoKnTs.
To all whom t may concern.'
`Be it known that l, ANTONIO PAPINI, a having resided in the United States one year last past and having declared my intention. of becoming a citizen thereof, residinV in the'city and county of Philadelphia, tate Of Pennsyl-V Vania,
have invented a new and useful Switch Current-Regulating Plugs and Sockets, of which the following is a specilication.
My invention consists of a novel construction lof a switch and contact mechanism for an electric regulating plug and socket wherein I employ a porcelain body having a portion thereof attened and adapted to support a plate or bracket carrying two pins secured thereto, one of said 'pins being adapted to'serve as a journal or a bearing for the switch operating mechanism, and the other of said pins serving as a stop pin to limit the extent of movement of the contact lever or its finger when the latter reaches either of its eXtreme positions.
It further consists in a novel manner of assembling the contact lever and' its adjuncts, and in a novel arrangement of a tension device intermediate of said contact lever and the shank of the insulating key, whereby a proper tension isy at all times iinpart'ed to the contact lever, according to requirements.
It further consists of -a novel manner of assembling the porcelain body portion, the plate carried thereby to which a plurality of pins are secured, the contact lever, the operating spindle which carries said lever and the means for creating a tension upon said contact lever, whereby said partscan .be readily assembled or disconnected for the.
purpose of inspection, replacement and re-A pair. y
For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has beenA found in practice to give satisfactory and-v reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and Organized and that my invention is not limited Ato the precise ar- Specicaton of Letterslatent.

mentalities as herein shown andl described.
Figure-1 represents a side elevation of anelectric current regulating plug and socket, switch and contact mechanism embodying' my invention, the Outer casingthereof and lits adjun'cts being shown in section. l
lF ig. 2 represents a Itop view of Fig. 1
jwith the top of the in closing'case removed.
Fig. 3 represents-on an section on line 3-3 Fig. 1. c y Similar numerals of referencev indicate enlarged scale a' Referring to the drawings.,
1 designates my novel construction of l switch and contact mechanism, the` saine comprising the body -2 of porcelain or similar material having the attened portion 3 on which the plate or bracket 4 of brass or other material is fastened.
5 designates the socket or lamp holder, and 6 the case inclosing the operative elements, said case having the flanged top 7 on which the cover 8 is spun or otherwise secured, thereby forming a compact and cheaply assembled device, said casehaving an annular lower row of holes 9 therein, and said cover having also a row of holes'therein, as indicated at 10.
The bracket t has the central disposed pin 11 and the stop pin 12 rmly riveted or secured thereto, as will be vunderstood from Figq. v
13 designates a squared shank spindle,
which is rotatably mounted on the pin 11, v
soy
said spindle carrying the contact lever 14 A lwhich is rotated in unison with said spindle ment of the contact lever 14 within predetermined limits.
The spindle 13, canrotate freely upon the pin 11 as a bearing and is provided with the terminal flange 17, which bears against the bracket or plate 4.-
18 designates a portion of the electric current conveyer. or plate, which projects through the porcelain body 2, as will be -understood from Figs. 1 and 3, with which p said stoppin 12 will limit the eXtreme inovethe outer end of the finger 15 of the contact plate contacts, the latter having an inwardly deflected portion or foot 19 (see Fig. 3) which rides on the plate 4 which is held in position on the body 2 by any suitablemeans as the lips or deflected flanges 20, said foot assisting to properly position the contact lever at all times.
21 designates a hole through the cover 6 counter bore or recess 26 therein, in which one end of the -coil spring 27 is housed, the opposite end of said spring bearing on the contact arm 14,- so that the finger 15 of the latter is always constantly pressed against the contiguous surfaces of the electric conductorilS, thereby insuring an uninterrupted flow of current to the .desired point and a smooth operation of' the various moving parts.
Such other parts of my novel device as has not been moreparticularly referred to are of the usual construction and their function and manner of operation will be readily apparent to those skilled in the art.
It will be seen from the foregoing that the bracket or plate 4 can be readily assembled with respect to the porcelain body 2 by means of the lips or flanges 20 and that the contact lever 14 can be readily assembled with respect to the spindle 13, which latter has its bearing upon the central pin 11 and the contact of the stop pin 12 with the upper and lower terminals of the slot 16 will limit the movements of the finger 15 within predetermined limits as is evident, and when the device is assembled as seen in Fig. 3, it will be apparent that the tension of the spring 27 will cause the' foot 19 and the finger 15vto properly contact with their contiguous elements, the free endv of the finger 15 particularly contacting with theconveyer 18 in a proper manner. The yrotation of the key 23 will actuate the .contact finger 15 to the desired extent with respect to the conductor or conveyer 18, as is evident.
When the device is assembled the moving elements in the case 6 are effectively housed therein and so are rendered inaccessible and" prevented from disintegrationl in handling or moving the device. 1
The principal elements of my device can be readily stamped, punched, or pressed out of sheet metal and can be readily assembled without the employment of skilled labor,.as is evident.
viaaoei It will now be apparent that I have devised la novel and useful construction of switch and Contact mechanism for electric current regulating plug and socket which embodies the fea-tures of'advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described' a preferred embodiment thereofl which will give in practice satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
Having thus described my invention what I claim as new and desire to secure by Letters Patent, is z- 1. In a device of the character stated, an insulating body having a flattened wall, a plate secured thereto, a bearing pin secured to said plate, a shank having its bearing on said pin, a contact lever mounted' on said shank, a key engaging said shank, tension devices intermediate said key and contact lever, and means for limiting the movements of the latter.
