Application flied my 1c, 1911., Serial No. 626,302. Renewed March 23, 1918. Serial Ho. aaasci.

i c all whom my Be it lmown that l, Enwrn Assam, a citizen of the United States, of Somerville, in the county oi" Middlesex and State of Massachusetts, have invented certain new and im rovements in Methods of Protecting Commercial Paper, of which the following is a spec fication.

The present invention relates to a method of protecting checks, bonds, stock certificat w, notes and other cominercial pa or having money'value denoted on the ace thereof, and has for its object to prevent fraudulent alteration of the values or such papers indicated by the figures appearing thereon. More specifically my present object is to provide a form of protection for such papers additional to those shown in my prior patents numbered and dated respectively 849,715, April 9, 1907, 869,823, (Ectober 29th, 1907, and 936,399, October 12th, 19%.

The method which it is nay aim to cover in the present application. consists essentially'in forming the conventional symbols such as numbers, letters or other conventional characters, which designate the face value of the paper, by impressin the paper at a great number of closely ad acent, and

distinct'points, which points are so arranged, as by their combined impressions, to'show the form of the desired symbol, and

v at thesanae time mutilating the portion of the paper thus acted upon by puncturing the same at points intermediate the impressed points. Where the impressing points bear upon the paper, the surface thereof is depressed, and where the puncturing points pass through the paper, upwardly promoting burs are caused to rise above the 1 face; 'lhus' the symbols designating value are formed by alternate depressions and protuberances or perforations, which are so arranged as tofollow the outlines or the symbols, and which also are regularly spaced and alined. fl'iherefore the efiect made upon the aper by impressin a symbol cannot be literated to permlt superosition of another symbol indicating a "gher value. In order to make the impressions more I ordinarily employ ink or other coloring material which is a plied to the printing member and by t e latter placed upon the-sheet at the impressed points, mah'ng colored spots or dotswhich are more readily apparent to the eye than the depressions which are formed when the printing member is not inked. Preferably also the punctures in the paper are so made that burs are struck up from the face of the paper and. are raised above the inked spots, whereby to prevent inost efi ectually erasure of the inlr. in the practice of this invention, i prefer to apply the dots oi ink to the portion of the paper immediately surrounding the figures or symbols, leaving blank spaces of the paper to indicate such symbols themselves, but the essence of the invention is also found when the ink spots are so applied as to form the figures, leaving the areas immediately surrounding such figures blank.

in the accompanying drawings 1 have illustrated an apparatus capable of carrying my invention into efiiect, and also con1- mercial paper having my invention applied thereto.

Figure 1 represents a longitudinal sectional elevation of the ap aratus.

Fig. 2 is plan view or a part of a check or other commercial paper bearing symbols representing value applied according to my invention.

Fig. 3 is a View of one of these symbols on an enlarged scale.

Fig. 4 is a cross-sectional view of that part of the paper bearing the ymbol shown in Fig. 3, taken on line 4. of said figure, but representing the same on an enlarged scale.

5' shows one of the types by which the symbols are applied.

Fig. 6 shows the bed against which the paper is pressed by the type and by which the perforations between the deposits of ink made by the type are made.

The same reference characters indicate the same parts in all the figures.

describing my invention 1 will first briefly describe a form of apparatus by which it is carried into effect, but without explaining the same in great detail, because substantially the same apparatus is illustrated in Patent No. 986,399 above referred to. In the machine 1 represents a table upon which the check or other paper represented by 2 is laid when being stamped. Over the table is mounted a type wheel 3 having a number of types 4, which wheel is carried a shaft iourna led in hearings '5, f, in arm or bracket 8 Which is pivoted at 9 over the table 1. A space 10 is left, as shown, between the pivot and table to allow the paper to be inserted far enough to receive the impression at the desired point. 11 represents a gage which may be adjusted to limit the amount or" insertion of the paper. raising the handl 12 which is 'on the shaft 5 the bracket 8 may be swung about its pivot 9 thereby raising the type Wheel and allowing the paper to be placed under it. By turning the handle about the axis of shaft 5 the type Wheel which is connected to said shalt may be placed so that one of the types 4 may come into position for impressing the paper. W hen the paper is engaged by the type it is pressed by the latter against bed 13 shown in dotted lines in Fig. 1, and in detail in Fig. 6, set into the table and by the latter indented or punctured. The superficial area of the bed is equal to, or perhaps slightly greater than, of any one of the types, so that it acts upon the entire area of paper acted upon by the type, but on the opposite side of the paper from the type.

The types or print 1g plates, one of which is shown in 5, have numerous fiat-faced projections 1 which, when coated with in and pressed. upon the paper, leave isolated spots or dots of ink, and When not inked dearess minute areas of the paper. Preferably the projections are termed by makingtvvo sets of parallel grooves in the face or the marking die, the grooves 15 of one set being transverse and preferably perpendicular to those of the other set 16. Such grooves are suliiciently naroW and spaced so far apart that the ends of the interme diate projections have area enough to leave deposits of ink of matenal size. In the par ticular embodiment of the invention here illustrated the number or other conventional symbol is formed on the paper by leaving" a blank space of the paper surrounded on all sides by the dots. Accordingly to produce this result the type is provided with a recess havin the outlines oi the figure, but reversed, as indicated in Fig. 5. t is Within the contemplation of my invention, and would not be a departure therefrom, to arrange the projections 14 in the reversed form of the symbol, thereby printing'the symbol in the form of a collection of dots arranged in the form of the symbol. That is the marking member Would be provided with a raised portion corresponding to an ordinary printing type, but cut across its iace by intersecting grooves.

The bed 13 against which the paper is pressed by the printing member has its face cut by intersecting grooves 17 and 18 which are spaced equally and aline parallel to the corresponding grooves 15 and 16 oi the printing member. 'llhe grooms are of such Width,'h0\vever, as to reduce the ends of the projections left between them to comparatively sharp points 19. 'lhe bed'is so placed on the machine with reference to the printing members that the rows of points on the bed "will enter the grooves 15 and 16 of the die When the latter is pressed toward the bed and "will thus puncture the paper at'the intersections of the blank lines between the dots thereon. Thus the points mutilate the paper between the areas upon which ink is deposited and in so doing raise burs upon the face of the paper whirls the inked areas and prevent erasure of the ink thereon.

The effect on the paper is illustrated in 3 and l, "from. which it will be seen there is a plain area 20 outline eo responding to the symbol surrounded on all sides by isolated small depressed areas 21 upon Which are deposits of ink, and between which are sharply raised and perforated projections 22. in the embodiment of the invention above suggested, Where the pro.- jections it are arranged in the tern; of a symbol, the effect upon the paper is to produce number of inked depressions and perforated raised protuberanoes collectively making the term of the symbo While space around such symbol is blank.

here tm ioregoin description l have used the term ink, it as been my intention to include any coloring matter suitable "for use in Writing or printing.

1 lo i r l. The method of protecting oommereial paper, which consists in impressing the surface of the paper at a multiplicity oi closely adjacent points so arrangedas eollectively to designate a conventional symbol upon t e paper, and puncturing the paper edi scent to the several impressed points.

2. The method of prote ting commercial paper, which consists n; applying to the surztace of the paper a, collection of isolatsd do posits of inl; so arranged as collectively designate a conventiona ymbol upon the paper, and puncturing the paper from the. side opposite to that upon the ink is deposited at points to each of the deposits of ink.

3, A method of protecting commercial paper which consists in impressing one side or the paper over numerous relatively minuteareas, separate from one another and are ranged in distinct roars, leaving an intermediate area of tie paper, in the term of a conventional symbol, unimpressed, and puncturing the paper in the spaces between the impressed areas,

41. A method of protecting eommereial paper against alteration at the value indi= cated thereon which consists in forming the conventional figure upon the paper by depotleu thereon of isolated. eat or ranged in parallel rows and collectively forming the outline of the symbol and puncturing and raising the surface of the paper between the spots.

5. Commercial paper having applied to its face a collectionof dots separated from each other by blank spaces, and so arranged as collectively to indicate the outlines of a conventional symbol, and having in the spaces between the impressions, raised portions.

6. Commercial paper having blank areas in the form of conventional symbols surrounded by inked spots arranged in parallel rows, and having rows of perforations intermediate the rows of inked spots.

7. Commercial paper bearing on one face dotted impressions of substantially equal length and breadth separated from one another on all sides by blank spaces, such impressions being grouped to form the outlines of a conventional character and to fill the spaces between adjacent characters; and the paper being raised in the blank spaces between said impressions.

8. Commercial paper having on its face a collection of distinct and separate impressions, the collection being interrupted in'the middle ortionby a blank space having the form of a conventional character, whereby such character is formed of the body of the paper itself and is defined by the surrounding impressions, and the paper being further punctured in the openings between such impressions.

9. Commercial paper having a collection of isolated deposits of ink and perforations arranged intermediate such deposits, the ink deposits and perforations being discontinuous in the central part of such collection, to leave a blank unperforated and un ressed space of the paper having the form 0 a conventional character.

10. Commercial paper having a collection of perforations interrupted in the central portion to leave a blank space in .the paper having the form of a conventional character and outlined by such perforations, the paper being inked in the spaces between the per-- forations.

11. The method of protecting commercial paper which consists in punoturin the paper from one side thereof at a multiplicity of isolated points; in impressing the opposite surface of the paper around said points, to assist in said puncturing operation, over an area designed to form a printing character; and in applying ink to said impressed portion of the paper for marking said character.

12. A commercial paper, such as a check,
