AP ION FILED MAX- 6, 1920- 1,385, 1 68, Patented July 19,1921;

UNITED, STATES State of Minnesota, have invented certain new and useful Improvements in Check- Protectors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use theme. I

My invention hasfor its object to provide an extremely simple, yet eflicient check protector, capable of being made in small size that is adapted to be carried in a vest pocket; and to such ends generally stated,

the invention consistsof the novel devices and combinations of devices, hereinafter described and defined in the claims.

The device is preferably made in disk-like form and comprises three main elements to wit: A disk-like dieplate,-asdisk-l1ke stripper plate and a punch plate, the latter being formed with radial punch arms, and the three plates being connected at their centers by a rivet or the like.

The punch arms are provided with heads having punch pins arranged to form characters, and these punch pins work freely through the openings in the stripper plate but closely fit correspondingly arranged perforations that afford pin seats in the die plate. The stripper plate is spaced from the die plate far enough to permit a bank check to be freely inserted edgewise between the same. The punch arms are of spring tempered steel and they normally stand away from the strlpper plate with sufliclent clearance to permit the punch pins to be forced from their normal or retracted positions down throu h the check and into the perforations or pm seats of the die plate.

The improved check protector is illustrated in the accompan ing drawlngs, wherein like characters in icate like parts throughout the several views.

Referring to the drawings:

Figure 1 is a plan view of the check protector, a portion of the bank. check being indicated by dotted lines; 1

Fig. 2 is an enlarged fragmentary view of a portion of the protector, said parts being shown in plan view;

Fig. 3 is a plan view of the die plate, other parts of the protector being removed therefrom; and

a Specification of Letters Patent.

Patented July is), 1921.

Application filed March 6, 1920. Serial No. 363,727.

Fig. 4 is a section on the line. 4c-4 of Fig. v 1 1 The disk-like-die plate is indicated by the numeral 5 and the punch seats, which are perforations inthe seat plate, are indicated by the numeral 6. These perforations 6 are arranged to represent the different characters and are shown. that there are 10 of these characters, includingthe digits 0 to- 9 inclusive and in addition an 11th character, the latter being of two rowsof parallel lines of perforations and which latter character, it may be here noted, will be used before the first punched numeral and after the lastpunched numeral applied to the check. a v

The stripper plate is indicated by the numeral 7 and the so-called punchplate is indicated by the numeral 8, the latter being of smaller diameter but having a plurality towit, eleven radially projecting spring arms19, that terminate in-heads 10. The heads 10 are preferably thicker than the arms 9 and they are marked with the numeral or characters corresponding to the digits and the additional character on the die plate. The three plates 5, 7 and 8 are rigldly connected at their centers by a rivet l0, and spacing Washers 11 and 12 are in terposed respectively between the plates 5-7 and 7-8, the washer 12 constituting a gage for the edge of the check. (See particularly Fig. 4.)

The heads 10 of the several spring arms 9 are provided with punch pins 13, which as is already stated, work freely through the stripper plate 7 and are arranged to corre spond to the perforations 6 of the die plate. so that one punch pin will enter each of said perforations when a head 10 is pressed toward the die plate. The spring tension of the arms 9 is such that the punch pins 13 are normally retracted from the perforation 6 and will be drawn into but not through the stripper plate 7. (See Fig. 4.) The so-called punch plate 8 and its arms 9 are preferably stamped from a single piece of sheet steel that is capable of being spring tempered and the rivet 10 will be so tightly applied that the punch pins 13 cannot get out of alinement with the cooperating pin sheets of the perforating die plate 5.

In Fig. 1 a portion of a bank check is indicated by the character 2 The manner of using a check protector of this general. character, is of course, well understood.

The check may, of course, be inserted freely between the stripper plate 7 and the die plate 5 With the particular character or numeral that is to be punched in proper poi opening or'drotches'? located between the punch heads 10 and extended radially inward thereof, sothat the ope 'ator can read ily see on what part of the check the char aeters. are being punched, and thus goodalinement, and proper spacing of the several characters 'on the check is made possible. i

In practice, this check protector has been made of such small size, that it will be contamed "and concealed ent rely in 'a vest pocket, but is nevertheless found to be :highly' efiicient for the purposes had in V16W.' i

.' What I claim is: I r

1 A check protector adapted to be carried in a check book having in combination. a die plate having perlbrations forming the characters to be punched, said perforations being constructed as female die members opening through the bottom of the protector and being unobstructed to permit discharge of the punehings, a stripper plate circumferentiallynotched and formed with radial projecting portions having perforated characters alining with the perforations in said dieplate, and a punch plate having radial arms carrying punches arranged to form the characters to be punched, the ends of said punches being flat and perpendicular to the sides thereof and adapted to cooperate with the dies in the die plate to completely sever the portions of the check, said stripper plate being disposed between the die and punch plates. i

2. The t'Oll'lbilltltlOll set fortlrin claim 1, and a circular washer llltOl'POSCtl between the punch plate and stripper plate and constituting a gage member with which the edge of the check is adapted to contact.

In testimony whereof I allix my signature iii-presence of two \vitnesses.
