l lii' fifigi Specification of Letters Patent.

Application filed December 15, 1919.

To all w/iom it may concern.

.l 'lc it known that l, ll'rixnloiri llxwixsiutr, a subject of the Emperor of Japan, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful improvements in Checks, of which the following is a specification.

ily invention relates to improvements in bank checks drafts or similar monetary instruments, and resides in the provision of an instrument of this character which is not subject to raising or fraudulent alteration.

@ne of the objects oi? my invention is to provide a monetary instrument of the character described in which the payees name, figures and other indicia by which the value of the instrument is determined or any indicia wiich might be fraudulently altered, all appear in iniperi'orate unmarked form surrouudeo on all of the margins of all of the tor of such indicia by perforations, i pe 1': ions define the margins of the characters oi the indicia and make fraudulent alteration without detection impossible the present embodiment of my inienlion as shown in the drawing 1 designates a ban i check of usual form sure for the features my inx'ention embodied therein.

The payees name on said check in pres ed or imprinted on the check in preferably impertorate unmarked letters 2 and surrounding these letters and defining the margins thereof so as to fill up all of the spaces immediately around them are perforations 3 Patented Jon 0 1M), 1922.

Serial No. 345,027.

formed in any suitable manner in said check. T he amount indicia at 3', the check number i and the written out amount indicia at 5 are likewise formed with imperforate characters 6, 7 and 8 respectively surrounded by marginal perforated portions 910 and 11. The

perforated portions are divided into squares or blocks separated by lines of imprint designated 13. Other indicia may be formed as hereinbefore described and it will be seen that by having perforated portions in the check or instrument, defining: the letters or numbers it will not be possible to fraudulently alter the indicia by filling in the perforations as is sometimes done where the indicia is of perforated characters.

The characters in thus being surrounded by perforations which fill up the imprint so as to leave no space between two adjacent characters or groups thereof or between two lines cannot be altered or changed by cutting out or filling up the perforations and imprinting other characters or by imprinting characters between the originally imprinted characters, without mutilating the check.

I claim A bank check having certain indicia thereon in imperiorate form and perforations in said check surrounding and defining the margins of the characters of the indicia, and lines 035 imprint between the characters of the indicia separating the perforations into blocks surrmuiding each character.
