ELECTRIC TRANSFORMER x 'I Filed Sept 11, 19:50 2 shuts-shoot 1 .INVENTOR ATTORNEY Patented Mar. 15, 1932 I" nowlun 3.1mm, or 203mm, oaneon i I PATENT OFFICE memo rmsrommn Application filed September 11, 1880. Serial No. 481,271.

My invention is intended for use as a transformer and may be used with equal facility upon direct current as well as upon alternating current systems.

6 The invention consists in its preferred embodiment of a pair of independent electric circuits with a contact bar interposed within the circuits and then the other alternately with a vibratory action being imparted to 10 the contact bar by the inherent spring action of the contact bar in one direction and by a solenoid core when one of the circuits is energized in the other direction to thereby shunt the current fir'st through one of the circuits and then through the other.

- One of the objects of my invention is to provide a transformer that may be used with equal facility upon either alternating or direct current for transforming the same from low to high voltage. A}

A further object of invention is to so construct an electric transformer that it may be used in the transforming of either direct or alternating current to a sufiicient intensity to illuminate neon tubes either from a battery or from any other circuit of electric current, either of the alternating, or direct current type.

A still further object of my invention consists in providing a relatively simple electric transformer that maybe cheaply made and efficiently used for the transforming of electric current from an alternating or direct current to a higher voltage.

And a still further object of my invention consists in providing an electric transformer that may be used as a universal transformer in the increasing of voltage of an electric current for the illumination of neon tubes, or for any other purpose.

With these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claim, and a preferred form of embodiment of which is hereafter described with reference to the drawings which accompany and form part of the specification.

In the drawings: I I

ike reference characters refer to like parts throu bout the several views.

1 illustrates the source of electric energy which may be a storage battery or any other source of low tension current, either alternating or direct current. The current flows through a conductor 9. to a common terminal post 3. The vibratory bar 4 is fixedly positioned upon its one end to the terminal post 3. Breaker points 5 and 6 are spaced apart and m are dis osed upon the oppositely disposed sides 0 the vibratory bar 4. Current flows from the contact bar 4 to the breaker oint 5 and into the electric conductor 7 an from there through the low tension coil 8 back to 5 the source of sup ly. As the low tension circuit 8 is energized the core 9 attracts the bar 4 breaking the contact between the contact bar 4 and the breaker point 5 to thereby break the circuit described and to cause the coil 8 to inv duce a higher tension current in the secondary coil 10 thereby permitting the electric current to flow through the conductor 11 and through the neon tube 12 to be illuminated, or through any other device, or element, requiring high tension current to flow therethrough. The condenser 13 is placed in parallel with the low tension coil 8, breaker point 5 and tenni nal post 3. YVhen core 9 disconnects the breaker point 5 from the bar 4, breaker point 6 is closed relative to the conductor bar 4 and the electric currents flow from this source through the conductor 2 the terminal post 3 the conductor bar 4 the breaker point 6 the conductor 14 the low tension coil 15, back to its source and simultaneously therewith inducinghigh tension current within the high tension coil 16 and simultaneously with this occurring; the core magnet 9 is released from the contact bar 4 and the inherent spring action disposed within the contact bar 4 causes the same to contact with the breaker point 5 thus competing this cycle of operation. The condenser 13 is placed across the breaker point 6 and the terminal post.

Referring to Fig. 4 the conductor bar 4 is made of spring material and a lug 18 is disposed at one side of the terminal post 3 having an adjusting screw 19 disposed within the lug and contacting side of the conductor bar 4. The breaker points 5 and 6 are so placed and arranged that a bow, or bend, is placed within the bar when the core 9 is energized and draws the contact bar 4 from engagement with the breaker point .5 and into contact with the breaker point 6 to thereby inherently tension the contact bar 4 and to give the same a reflex action when the core 9 is released from magnetic contact with the under side of the contact bar 4. This action facilitates the immediate return of the bar 4 into engagement with the breaker bar 5 when the core 8 fails to be energized.

I place my assembly within a box-like container 20 and interpose an insulating block 21 .between the primary wall of the box andthe assembly secured thereto. High tension connections are disposed at oppositely disposed sides of the box at 22 and 23 with insulation 24 and 25 being dis sed between the metal box and the terminal connections. The high tension connections are made at 26 and 27 with insulation blocks 28 and 29 being disposed between the terminal connections and the container. A lidded closure 30 is rovided at one side of the box with suita 1e electric connections connecting the terminals with associated elements disclosed therein, as heretofore described.

In some classes of work and on certain voltages it may be necessary to place a flexible contactor 31 upon one side of the conductor bar 4 and place a breaker point 32 thereupon that is in registerable engagement with and contacts with the breaker point 6, in order that the contact may be completed across the gap 33 in advance of the closing of the gap 34 between the conductor bar 4 and the solenoid core 9.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of-the claim which follows.

What I claim is:

A device of the class described, a lidded box, high tension connections disposed through the walls of the box and insulated therefrom, a pair of coils disposed within the box, electric circuits interposed within the box and connecting the terminals with the coils, condensers disposed within each of the circuits, a terminal post disposed within the circuit and secured to the box, a vibratory bar connected to the terminal post, a flexible contactor secured to the vibratory bar, means associated with the post for precisely positioning the vibratory bar, breaker points spaced apart and disposed in registerable alignment with the vibratory bar and upon oppositely dis osed sides of the vibratory bar and a so enoid core disposed in registerable alignment with the vibratory bar and adapted for being momentarily engaged by the bar core when the solenoid is energized.
