CHECK FROTECTOR.

Application filed March 19, 1.923. SeraI No. 626,055.

.To aZ whom it may concern:

-Be it known that l, THOMAS R. Gnoien, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Check Protector, of which the foliowing is a specification.

There are at present employed, several types of chock protectors by which the pap-er forming the check is out into and disrupted over the written amounts and signatures so that erasures and alterations cannot be made and also there are at present employed check writers whereby the amounts for which the check is drawn is cnt into the paper by .means of lettered dies. The check writers 'now employed give very satisfactory results 'as far as unchangeability of amounts, but require much time in their operationas the machine must be reset for the writing of each separate check. The check protecting device which merely' macerates the paper over the written amounts destroys the structure of the paper and provides a roughened surface .upon the baclr thereof which interferes with lthe imprinting of endorsement stznnps on the back4 of the check.

It is' an object of my invention to provide a protective device whichwill imprint the ent-ire check with perforations, these perforatio'ns being indented from the back of the check and over the whole surface thereof, 'whereupon a substantially smooth surface is maintained upon which endorsement stamps niay be' easily printed. This device employs a die or extruder roller and a cooperating 'roller between which the sheet to be protected is passed, the die roller having ein truder points thereupon extending substantially the full width thereof so that the entire surface of the sheet may be perforated.

lt is a further object of the invention to provide a means whereby the rollers may be separated so that. portions of the sheet being passed therethrough will not be perforated, thus lallowing an area upon which an endorsement olf-'other writing may be placed.

The especial advantages of the invention and further objects thereof will be. made evident hereinafter.

Referring to the drawings which are for illustrative purposes only,

Fig. 7 vis a view taken as indicated by the line 7-7 in Fig. 4 showing one of the end plates employed in the construction of the check protector.

Fig. 8 is a fragmentary view of the end plate, this view being taken as indicated by the arrow 8 in Fig. 4.

In the form of the invention shown a base plate 11 is provided upon which is secured aV housing 12. This housing as shown in Figs. 2 and 4 consists of a pair of stamped end cover plates 13 and 14 between which a plate 15 bent to forni the side walls and rounded top is disposed. Vifithin the housing 12 a pair of stamped end plates or standards 17 are placed in upright position, these plates being held in spaced'relationship by rods 18 provided with nuts 19 and tubular spacing members 20. At the lower corners of the plates 17, bosses 22 are formed into which screws 23 extend as shown in Fig. 4 for the purpose of holding the end plates and the surrounding structure 12 upon the base 11. Near the upper end of each plate 17 a sleeve 24 is mounted, these sleeves each having a cam 25 thereupon as shown in Figs. 4 and 7 and receiving the reduced ends or trunnions 26 of a die roller 28. This die roller has a gear 29 mounted at one end thereof which is driven by a small pinion 30 mounted upon a shaft 31 which extends through a drill sleeve 32, as shown in Figs. 4 and 7, and the end cover plate 13, and has a crank handle 16 mounted upon the outwardly extending end thereof. Situated below the die roller is a cooperating roller 35 having a gear 36 and being supported between sleeves 37 formed upon swingable plates 38 which pivot upon pins 39 and have the swingable ends 40 thereof held resilient ly and pressurably upward by springs 41. The action of the springs 41. serve to hold the cooperating roller upwardly in a posiv tion indicated in Fig. 2 and by dotted lines 43 in Fig. 7. The cams 25 serve as stops for limiting the upward movement ofthe plates 38 and thus determine the maximum spacing between the rollers 28 and In the front 47 of the housing a wide opening formed by guide plates 48 is disposed in a position to direct a. check 49 or other sheet of paper through the rollers 28 and 35 as shown in Fig. 2. In the back 50 of the housing 12 an exit opening 51 is provided confined by inwardly extending guide lips 52 which receive the forward end of the check as it leaves the rollers and directs it out through the back wall of the housing. A guide tray 53 is hinged at 54 upon the front of the housing 1-2 so that it may be swung into guiding position as indicated in full lines inFigs. 1 and 2 or may be dropped aga-inst the front 47 of thc housing as indicated by the dotted lines 55 in Fig. 2.

As shown in Fig. 3 of the drawing the die roller 28 is provided with evenly spaced extruder points and the cooperating roller 35 is likewise provided with indentations 61 into which the eXtruder points eX- tend. It will be noticed that the eXtruder points GO are located enti-rely upon the die roller and that the outer surface 62 of the cooperating roller 35' is substantially cylindrical. I

In the manufacture of the device, a metal is employed for the cooperating roller 35 which issomewhat softer than the metal employed for the die roller 28 and the indentations 61 are formed by placing the two rollers together and rotatingv undea' pressure. The gears 29 and 36 synchronize the rotation of the two rollers and thus cause the extruder points to coincide at all times with their cooperating indentations in the roller 35.

1n the use of the device a check or other negotiable paper has the amount, signature, or other notation written thereupon, whereupon it is placed face downward upon the guide tray and the end thereof inserted between the lips 48 so as to be brought into a position where it will be drawn through the rollers upon rotation thereof by manipulating t-he crank 1G. It will be recognized that the perforations indented' in the paper by the eXtruder points 60 will be accomplished entirely from the back of the'sheet and will result in a substantially smooth etfect of the back of the sheet anda multiw plicity ofv extruded ,projections upon the front of the sheet which cannot be written over without the appearance oflink spots upon the front and back of the sheet. Any attempt at erasure and alteration of the check is easily discernable and the character of the extrusions is such that they cannot be iron'ed out owing tothe fact that each extrusion is perforated so that the texture of the paper is broken. These extruded points, however, are spaced suliciently far apart so that the strength of the paper is not materially diminished. The fact thail the entire surface of the check is extruded also has the effect of making the erasure or attempted erasure of any part easily discernable, as by an attempted erasure the evenness in appearance of the extrusions 1s very pronounceable. As hereinbefore mentioned the' back of the check presents a substantially smooth surface upon which an endorsement stamp may be printed.

The invention provides means whereby the rollers 28 and 35 may be separated to allowv the passage of any portion of a sheet of paper therebetween without being perfo rated by the extruder points. This means consists of a small lever which is mounted upon the outwardly extending end of a shaft 71 at the end ot' the housing 12 opposite to the crank 16. The shaft 71, as shown in Fig. 4, extends through the end cover plate 14 and the end plate 17' upon which the cover plate 14 rests and the inner end 73 thereofis received in the end plate 17 upon which the end cover plate 13 is mounted. Adjacent to the end plates 17 collars 75 are pinned or otherwise secured upon the shaft 71, these collars being provided with projections 76 as shown in Figs. 2 and 7 which rest against the downwardly extended portions 7 7 of the plates 38. The shaft 71 may be rotated in the direction of the arrow 78 in F ig. 2 by pulling the upper end of the lever 70` toward the operator, this rotation of the shaft moving the projections 76 into the positions indicated in full lines in Fig. 7, and thus causing the plates 38 to be rotated downwardly against the action of the springs 41 and the cooperating roller thereupon being drawn downwardly out of engagement position with the die roller 28. Upon the release of the lever 70, the springs 41 return th.;r plates 38 to their positions against the cams 25 as indicated at 80 in Fig. 7. The posin tion of the cams 25 may be adjusted by rotating them upon the sleeves 24, there being provided set screws 81 by which the cams may be locked in desired position upon the sleeves 24.

As shown in Figs. 5 and G'the invention provides means whereby die inserts containing thereupon secret characters, symbols, or wording which is to be indented in the check, theseinserts being removable so that the characters or inscriptions thereupon nlay be changed as desired. In the die roller 28 shown in Figs; 5 and (i av longitudinal channel 85 is formed which receives a metal strip 86 having'characters as indicated at 87 upon the face thereof. The characters are preferably outlinedv in evenly spacedex- Li o trnder points which cause the perforation of their particular arrangement in any paper which may he passed between the rollers of the device. Several of these die inserts 86 may be employed as desired and may be changed from time to time as conditions may require.

An advantage of the invention is that by its arrangement of cutters or extruders upon the die roller, the entire face and body of a checl; er other instrument may be impressed with extruded portions orv points, the apexes of which constitute clear, clean and perfect perforations, without materially affecting the strength of the paper, and that at the same time a smooth surface on the back of the check is provided so as to admit making thereon a clear and distinct `impression with a metal or rubber endorsing stamp.

Another advantage of the invention is that by distributing` a multiplicity of perfor-ations over the entire face of the check or other instrument any attempt to remove the printed numbers or written portions thereof by means of acids or otherwise, for the purpose of making alterations, will at once be discernable on the front and the hack of the check as the ink used in making alterations fiows into the perforate indentation and causes the spreading of the inl( upon the face of the check as well as its appearance upon the back thereof.

additional advantage of the invention is that by means of the pressure release located at the end of the check protector, the operator is enabled to disengage the cylindrical die, hy which operation a perfectly smooth surface is obtained on both the face and the back of the check for the purpose of facilitating endorsements with pen and ink on any desired portion of the instrument.
