CHEGF-PROTECTING SYSTEM AND KEYBOARD FOR Application led September To all I071.01m t may concer/1t.-

Be it known that I, HAMLET Corsican, a citizen of the United States, and residing at Fast Rochester, in the countyV ot Monroe and State of New York, have invented certain new and useful improvements in Check-Protecting Systems and Keyboards for Same, of which the following is a specification.

rThis invention relates to key-boards for use in a system of negotiable instrument protectors or identiiiers.

nn object ot' my invention is to provide a key-board consisting of a simple device which bears a number of arbitrary characters, such as numbers, letters, sign characters, and the like, that may be copied therefrom upon a check, draft.` note, postal money order.` or other certicate of value.

Another object of my invention is to provide a keyboard which has movable parte, and which when set to definite reference numbers or characters will indicate the sum for which the check or other paper was originally made payable.

Another object of my invention is to pro vide means whereby the key-board may be changed periodically, by changing the places of interchangeable parts.y so as to completely alter the system ot numbers and letters of the'entire board. thereby increasing the diiiiculty of interpreting the reference numbers by unauthorized persons.

Another object of my invention is to provide a chart or scale, or table card, with numbers, letters, or characters, or combinations thereof printed thereon, from which reference numbers may be obtained to be written on a check or other negotiable paper or certificate of value, and which reference number will correspond to the sum named on the check or other paper.

Other objects will appear upon reading the specification and drawings.

In the accompanying drawings Figure l is a plan view of the key-board;

I

In Fi'g.r 1, a board, or thick plate i ot suitw able material is provided with a plurality ot channelsH 2, Fig. 10,.in` which are placedV slides 3, Fig. 2. Upon the face of the board, upon each side of the facev of the slides, are placed rows of numbers, 4e, arbitrarily placed, there being no particular system or order in" which the numbers follow each other; generally, the more` confused thek numbers are, the better. .:pon the face of i the slides', beginning at the left`,is the alpha# bet;- follo'wi'ng the alphabet isl a hol'e 5, seef Fig.y 2, and following the holeis a row of digits. The slides have` portions of `their runners cut away7 as at 6, Fig. 2, the l0- catioii and amount ot' runner cut away may varyamong the slides, yso that upon changing from one channel to,` anotlier,.tlie slides'. will give different readings.` thereby permit-V ting periodical' rearrangements' of the key board according to a codesystein, to increaseA l thesafety of the device aus a check protector. The slides are held in place an end plate 7,. Fig. 11, having slots 8 whlcht around the neck 9 of the slide.

The slides are provided with suitable handles 13.

InFigv, the slides are shown removed,

i. 'exposing "rows of digits at each end of the confused succession;v I() channels 2. thedigits vare' preferably` in a At the left hand end of `the key board,

Figs.' 1 and 5, areletter'blocks' V10,"Fig's 6 and 7,' which are arrangedto. be replaceable',

permitting their periodic relocation so as notjto follow consecutively, if desirech' aceording to a pre-arranged code, thereby aid-V ing. in rendering the key board more secure.

The letter blocks fit'inrecesses 11, Fig.,6,laty

the end of the key board, and are fheld in v place by the plate 12, Fig. i

Inuse, theslides are pulled out to varying extents,f. asdesired, as shown in Figs. 16

and 1 7. The locationof holes 5 Amay also i 19,., The principle of operation of the dis-k'r vary ondilferent slides to increase security ofthe device.'

.In Figs.. 12 of key boardis shown, in which the slides areshown-as incomplete rings 14, provided with handlesy 15. The slide rings 14:- move in channels or spaces between the` number vrings 16, `which latter have flanges 17 that are securedin grooves-18 inthe base plate "ftype' is the same as thatof the Smpl@In form shown in Fig. 1.A f

' The-modifications illustrated-.in Figs. 14

and `15 are operated onthe same principle as the types shown in Figs. 1 and 12. In

Figjll, the/.slides are shown as rings `encircling a cylinder; and in 15, theslides are shown as ringsencircling a cone at different elevations'. 1

In Fig-19 is illustrated. a checkfor" 105 $7531.64. 0n the chart, Fig. 18, at the left,

iop

are shown letter vblocks"1',,3, .4,5, 6,

upper rows 1, 2, 3, 4, arereserved for dollars, M

and the lowerrows 5, 6, T, 8, for cents. .Y The dollars in suin given ron thecheck, is spaced; ofi into `groups oftwo lfigures.. each', begin; ning'with .the decimali-point; y f f In Fig. 19,v wehavej two groupsy of ligwe find -7 in row-3? and-above the letter T-,so wewrite 3-..T, on a corner of the check gthe group .31 ofthe amount of. the check is found in row 27 on .the"char.t,

`ures, 75 .and 81. Onexamining the charty and below .letter D, so we write Q D?,

after 3l-T. on the check. A lineis vnow drawn under these characters, ,and ythe eripression for 64; cents is found by Vexamining the lower fourfrows lof figures on thechart. 64 appears' in row 7over pletter-#1Q7 so we write w-Kbelow the line under-"the characters for dollars. This compound nunr` 3-T, 2 1); 7*K` .1., A. number. In additionto the: above, .the

.time at which theeheck is signed is' noted 'is called.,` the* ,reference and correspomling characters obtained from the 'lirst two rows of ligures on the chart.

lf the check was signed at 99353, look for 9 in the row marked l, it ir over letter TC, the hour character will then be ll- 1, which written in another corner of the c ck: the minutes. willbe found in row under letter C, the minutes character will then be C-Q, which is written after Ta-l. on the check. The complete time character will then be lll, (1 -32,. The payors serial number, noted above, 7563, is also placed on the check.

rllhe check shown in 19, when presented for payment, at the bank, will be interpreted on the key board, beginning with the serial numberl` as described above. This process will develop the key board arrangement shown in Fig. 1T. The reference number 3-T, will be found by looking in row 3 over T to be 75, reference Q -D will be found in row 2 under D to be 3l-` The dollars will then be $7531; the cents will be found in row 7 over letter K to be Se, the original value of the check will 'then be found to be $7531.64. lf this does not agree with the sum named in the check, it will be evident that the cheek has been altered, since no two persons will have the same chart, shown in Fig. 18, and the person who altered the check would have no means of knowing the reference number on the chart in the possession of the maker of the check. also the time given in characters on the check would be interpreted by looking for letter U in slide 0, under l, which will be found to be 9, the minutes will be found bv looking under C row 2 and will be found to be 45% the check was signed at 9 If the person presenting a check for payment cannot recall the apprcnrimate time of signing it, it will be evidence that further investigation should be made before it 'is paid.

The principles applied and described for a check, may also be used on drafts, postal money orders, promissory notes. and certificates of value of other descriptions such as bonds, shares of stock, etc.
