ZAVERIO REV'ILIG DELLA VENERIA, O F TURIN, ITALY.
CIRCUIT-CHANGING SWITCH.
To all whom-it may concern l Be it known that I, ZAVERIO REVIGLIO DELLA VENERIA, a subject of the King of Italy, and resident of Turin, Italy, have i11- vented certain new and useful Improvements in Circuit-Changing Switches; and I do to which it appertalns to make and use the same, reference beinghad to the accompanying drawings, .and to letters or figures of reference marked thereon, which form a part of this'- specification.
This invention relates to a device for interrupting, commutating, reversing and deviating the electricj current characterized chiefly by the fact that the contact springs are dispensed with and the snap mechanism is greatly simplied.`
The chief advantages obtained by this in# vention are:
The switching on and oil' isefected instantaneously by a snappingloperation. The construction is very simple and economical as the device is constituted by the smallest possible number vof pieces and may be of Moreover the device may be used for any kind of plant and there are only two points of contactbetween the members to be con-1 nected or. disconnected. l
In'the annexed drawing is shownby way of'exa'mple a constructional form of this device.I y Fig. l is a longitudinal section on line A, B,Fig.2.'
Fig. 2 isa planview ofthe switch 'base with the contact plates. lFigw3 is adiagrammatieview of a plant. ,On the switch base 1 ofinsulating material are secured two pairs of'metallicplates 3.3,- 3.3 forming a ring lkept in place by means of pins 4.4, 4:.4 acting as terminals.
The plates 3 project from the bas/e to which they are secured andat the ring interruption points 6.6, 66
vthe ated (see Fig. 2). The switch cover to fully protect lthe contact plates. 'Said cover is of insulating material and is prowithla pin 2 having a secured by'means of a nut plate edges are arcu- Inside the cover 7 loosely mounted on the v`Specification of Letters Patent.
declare the following to be 'a' full,- clear, and exact description of the invention, such as will enable other skilled in the art riciently tensioned to 7 is bell-shaped in order pin 2 is a disc 16 .and between this latter and 16 and the contact plates are mounted two metallic balls 5 situated in two diametrically opposite cavities 16 formed in the disc 16. The spring 11 acting on the disc 16 holds the balls 5 constantly forced upon the contacts 3. y
As will be seen from Fig. 2 of the drawing, the plates 3.3 are connected with sim'- ilar poles, and the plates 3.3 also to similar' poles, but opposite to those of the lfirst two plates. Assuming the switch to be in the restiig position (that is the balls being in the spacesv of the contacts) the circuit will be open as each ball connects poles of the Isame sign.
Ofcourse'whenthe device is'used as interruptor, it may be suilicient to connect a single plate 3 with one a single plate 3 (adjacent to the plate 3) with the pole-of opposite sign (see diagram of Fig. 3, right hand side).
By causing the cover to rotate, the spring unwound till it is sufforce-the balls 5 out of the cavities 6 and by overcoming the inclination of the plates 3 said balls will be brought instantaneously .into the Acavities 6', thus connectingJ the plates of sign and closing the circuit.
` The above described device may be used without ychanging its copstructionbut'simply varyingv the relative position of the balls or line connexions for all ukinds of plan designs., f Y' L -101fshows an application as ordinary 1nterruptor (1'11).\
