JOHN J'. Bona, or rmannnrm, PENNSYLVANIA. ELECTRICAL P Earomron.

Application led Iay 17, 1922. Serial No. 561,712.

To all ,whom z'tmuzy concern:

Be it lown that I, JOHN J. Borna, a citizen of the United States, residing in Philadelphia., Pennsylvania, have invented B an Electrical Perforator, of which the fol-l lowing is a specific-ation.

The object of this invention is to provide.

simple and eicient -means 4for check protection. Y l

In the attached drawing:

Figure l, is a view in diagram of app aratus made in accordance with my invention;

Fig. 2, is a view in perspective of a modill ication within the scope of the invention;

Fig. 3, is a section on the line 3 3, Fig.

2, and

n Fig. 4, is a sectional view of a further` I haveV discovered means wherebyelectricl` l'ity' .with all its attendantadvantagesmay be used wlth entire satisfaction and .with a. total elimination of all for commercial usefulness. In practicing my employ Vapparatus of thet mployed in the So-called violet ray A although .other types. "f high -,frequency apparatus. may'bev employed where found y desirable. Such a`machine I have lshown digrammatically in Fig. 1 of the dra-wings, it consisting 'of an induction coil 1, the

primary circuit 2 of which may be connected to anyT Suitable ysourceot' current (not shown),nand thesecondary of which is vconnected with the .primary`4 of a Tesla coil. This4 secondary circuit 'of the induction coil, which includes .the primary.',winding' of the Teslaicoil, also includes aseries spark gap' 17 land a condenser .18 in parallel with thev co1 s.- of this Tesla coil the vided the paper by electricity, and this` havev gone into general use fundamental faults which .Inthis case,` the. objectionable .5 Y features which hitherto vhave disqualified itinvention,v I prefer'to machlnes for pro.. 40 'ducing an electric. current of high fmqumcyA One terminalx5 ofthe secondary 6- other terminal is connected in the present instance to a metal plate 7, a binding post 8 being provided on this plate for that purpose. In the present case alsoI have proplate 7 with a spring clip 9 at one side which .is adapted to hold or-other paper form l() to the plate during the writing operation.

. In apparatus'of this, it is only necessary to write the check in the usual manner, it

a check being possible to use apen of the ordinary o form. As the oint of t e pen contacts with the material ofp the check, minute discharges of electricity will pass from the charge vplate 7 through the material to the point of the pen, ythese discharges perforating the check and causing the ink to flow through the perforations and into the body of the paper.

- These discharges from plate to pen point continue as the pen is moved acro the paper, with the result that the latter is perV orated thoroughly along the liney of the writ-ing.A

Inorderto prevent the hand of the writei coming into direct contact with the charged plate, a device such as that 'illustrated in ig,4 2 may be employed, this consisting of av plate 11 of suitable insulating material having* a slot or opening 12 in which is established fa metalstrip or plate 13, which latter is connectedinthe manner previously described 4togthe highv frequency apparat-us.

plate 11` in--such position'th'at the line upon which the marks are to be made overlies the metal strip 13, the paper being perforated vwhen .the point o the pen comes 1n contact withthefpaper. In this case, how?v (ever, the hand' o the'v writer will rest upon the. platell and need not come in contact with the -metal plate.

, It will` be apparent that equally satis-y factory results may be obtained by; using a pen the point of which is connected to the high frequency apparatus instead of the the checkis placed upon thc metal plate upon which thel check is laid.

-A suitable pen for this purpose is shown kin Fig. 3, and may be of the ordinary fountain v type having an electrode or conductor 14 extending into the well 15 of the pen in such manner as to be continuall connected by means of a wire 16 to the secondary 6 of the high 'frequency apparatus. In

1 in contact f with the ink carried therein, t e electrode ..14 being electrically thscaseasbef plate beneath.

is subject to one ofthe main faults of the fore, the check is laid upon a metal plateA previously developed electrical perforating means, in that a special vpen is required having the wire. attached thereto, this wire preventing entire freedom in the manipulation of the pen.

In the apparatus illustrated in Figs. 1 and 2,'y however, and as previously stated, any ordinary writing pen may be employed,

the electric circuit, and it being accordingly given the entire freedom which is found in any ordinary writing operation. A further considerable advantage over the prior forms ofv electric perforatmg apparatus is also found in the fact that Yalthough the dise.

e charges'are sufiiciently strong to insure a thorough perforation of the paper, the character of the discharge is such as ixr nov way seriously to affect the operator ifhis handl should come in contact with the plate 7, and it is accordingly unnecessary to exercise any extraordinary care in `the use of this apparatus to prevent electric shock.

The apparatus will accordingly find universal use by all, and does not require special construction or expert handling such as is riety required in the previously developed forms of electric perforating devices. The a paratus is a simple one and .is comparative y cheap, and lends itself to a Vvaof modifications and renements to suit any'conditions of use.
