The present invention relates to voltage modifying means. More specifically, the in vention relates to a voltage modifying means of the vibrator type.

It is one of the objects of the invention to provide a voltage modifying means of the transformer vibrator type wherein I am enabled to multiply or divide the voltage from a given source of supply through the medium of a transformer vibrator circuit wherein I am enabled to dispense Witha large amount of material to thereby effect a saving of both material and weight.

More specifically, one of the objects of my inventlon is to provide a voltage doubler of the transformer vlbrator'type dispensing with the secondary winding of the transformer.

For the purpose of disclosing my invention, I have illustrated an embodiment thereof in the accompanying drawing, in which the figure is a diagrammatic view of the vibrator transformer system embodying the features of my invention.

In the embodiment of the invention illustrated in the drawing, the voltage doubling system comprises a transformer I having a split inductance winding, comprising two sections 2 and 3. The winding is provided with a center tap connected to one side of a battery 4. Preferably I provide a controlling switch for controlling the circuit. The opposite side of the battery 4 is connected to a vibrating reed or contact member 5 adapted to vibrate between a pair of oppositely disposed relatively stationary contacts land ll,'which are respectively connected to the and terminals of the inductance winding.

A second vibrating contact member 9 is connected to an output lead ID. This reed 9 vibrates between a pair of oppositely disposed relatively stationary contacts H and i 2. The contact l l is connected to the end terminal of the winding section 3 and the contact 12 is connected to the end terminal of the winding section 2. The opposite side of the battery l is connected to an output lead l3 between which lead and the lead H], the load may be connected.

The reeds 6 and 9 may be and usually are mechanically-connected to operate in synchronism and the reeds are driven through the medium of the driving magnet l4 having a winding l5, one terminal of which is connected to one side of the battery 4. The opposite terminal of the winding i5 is connected to a relatively stationary contact l6 adapted to be engaged by the reed 6 when the reed is in neutral position. Accordingly, when the switch 5 is in the closed position the reeds 6 and 9 will be driven in one direction by the magnot H and into engagement respectively with the and il, the circuit, through the Winding I5, is

broken permitting the reeds 6 and 9, under their momentum, to move into engagement with the contacts 8 and I2 respectively. At the same time the circuit of the magnet I4 is re-established. Accordingly the reed G is vibrated between the contacts l and 8 alternately making and breaking the circuit between these contacts and likewise the reed 9 is simultaneously vibrated to alternately make and break contact with the reeds l l and I2.

With the reeds 6 and 9 respectively engaging contacts 1 and II and assuming that the battery 8 delivers 12 volts, 12 volts will be supplied to a circuit including the battery, the winding 2, contacts l and the opposite side of the battery. Likewise 12 volts from the battery 4 will be delivered from the plus side of the battery 4, in the opposite direction, the contact H and thence to the plus output lead 10 and thence through the load by output lead l3 to the minus side of the battery. However, due to the 12 volts delivered to the winding 2, 12 volts will be induced in the winding 3 which superimposed upon the 12 volts delivered from the battery will result in 24 volts being delivered to the load. In other words, this voltage induced by the winding 2 in the winding 3 will double the voltage of the battery to the load.

likewise when the reeds B and 3 are engaged with contact 8, the 12 volts of the battery will be delivered to winding 3 from the plus side of the battery 4 to the minus side of the battery 4 through the contact 8 and reed 6. At the same time 12 volts will be delivered to the winding 2 and thence by contact I 2 to the plus side I 0 of the load. At the same time winding 3 will induce 12 volts in winding 2 so that actually there is delivered 24 volts to the plus side ID of the load.

, It is, therefore, apparent that with the single induction winding I am enabled to double the voltage delivered to the load from the battery 4. It will be understood, of course, that the voltages referred to are merely for the purpose of illustration as it is quite obvious that batteries delivering larger voltages than 12 volts may be used or any other source of supply may be used other than the battery.
