9 Claim.

This invention relates to check typing and protecting machines.

It is customary to employ perforating types in a check-typing machine for the purpose of indenting the paper. Other check-protectors havetype-dies which shred the paper.

The main aim of the present invention is to provide for simply and quickly protecting a check, without need for employing a machine which is 10 capable of nothing else than check-writing. This invention employs a standard typewriting machine, which, is illustrated as an Underwood typewriter; and the types used in this invention are standard types, as distinguished from perforating types.

The checks are attached in the form of a web, and, after the first check is typed, the web is advanced, and the typed check is thereby brought, with its typed amount line in register with a shredding die-mechanism that is provided upon the typewriting machine at the delivery side of the platen. A handle is then operated, and the dies are brought together upon the check to shred the same along its typewritten line.

' The check may be shredded for its entire width,

ample check-protection being thereby secured. The typing of the second check begins while the first check is advancing to the shredding position. Preferably when the second check is in position for typing the main amount thereon, the first check is in position to be shredded. The main amount is usually the last line that is typed on the check. After the shredding of the first check, it may be torn off, and then the web may be advanced forvbeginning typing of the third check. A check-shredding table is mounted to extend upwardly and rearwardlyfrom the platen above the printing line, and the emerging web travels 40 over this table, in which is fastened one diemember. above the table is secured a movable die-member;aiid the check-web is advanced between said die-members by means of the typewriter feed-rolls, which run upon the under side of the platen and press the check-web against the platen. I The dies are normally open, but are closed by means of a handle, thereby leaving each check in condition to be torn off from the web along a weakened line; although, if desired, a tearing-off knife may be provided upon said check-table, or the checks may remain intact until the entire web is typed. r The entire shredding device may be manu- ".factured and sold as a unit for attachment to an Underwood or other standard machine. This unitmay be removed, if it is desired at any time to use the typewriting machine only for ordinary typewriting P p ses.

There may be preserved a copy of the checks. 00 This copy may be made upon a record-sheet by the aid of a carbon. The carbon and the record-sheet may feed out from the machine above the platen and below the check-perforating table. The record-sheet may be used in connection with a condensed record mechanism, if desired, so as to space the items closely upon the record-sheet.

An objection arises to the use of typewriters for check-typing purposes, because the machine is infrequently in use, as there are not many checks to be typed, and the entire old check-writing machine is useless for general typewriting, on account of the check-perforating types with which it is equipped. The present invention provides for using the machine at any time for ordinary typing, while it is serviceable as a checkprotecting typewriter whenever desired. When the machine is used for ordinary typing, all the work-sheets may emerge from the machine over as) the platen and below the check-protecting device, so that the latter does not needto be removed.

The check-shredding dies are mounted to have the long axis of their work-field spaced from the printing field of the platen at a distance measured along the path of the check-sheet, equalling the distance between the lengthwise, parallel spaces of two adjoining check-forms provided for bearing the amounts of the checks in words. Then, when a check-slip of the check-sheet is positioned in the typewriting machine to have its amount in words typed in the usual space, the amount in words of the leading check is positioned between the check-shredding dies. After the amount .of the next following check is typed, a movement of the handle will then shred the leading check, and, when. the handle is released, the leading check is left free to be advanced to tearing-off position as the next following check is moved up to shredding position.

It is a further feature of the present invention to provide for handling checks of different widths. This is accomplished by providing adjustable means for mounting the shredding dies in different work-positions relative to the printing field of the typewriting machine.

Still another feature of the invention resides in making use of an eccentrically-mounted roller extending lengthwise of a movable die, for applying uniforrn pressure to it throughout its length,

for moving it into engagement with the lower fixed die.

Other features and advantages will hereinafter appear.

In the accompanying drawing,

Figure 1 is a perspective view of an embodiment of my check typing and protecting device broken away in part, which device is illustrated as including an Underwood typewriting machine, which is also shown in part.

Figure 2 is a view showing a partial cross-section through the structure shown in Figure 1. In this view the parts are shown positioned as when performing the paper-shredding operation.

Figure 3 is a partial cross-sectional view through the structure shown in Figure 1. In this view the sheet of checks is shown advanced to bring the leading check, which has been previously shredded, to tearing-off position.

Figure 4 is a view of a partially filled in check, protected against being raised, which illustrates one way checks can be macerated or shredded in a device embodying my invention.

My check typing and protecting device is illustrated as embodying an Underwood typewriting machine. It can be readily seen as the description proceeds that my device can be easily modilied to embody other makes of typewriters.

In an Underwood typewriting machine, types 10 strike against a platen 11 mounted on a platenshaft 12, which is journaled in end plates 13 of a platen-frame generally designated as 14. For guiding work-sheets around the platen from the rear, a rear paper-table 15 extends between the end plates 13, and lower feed-rolls 16 are provided to engage against the lower side of the platen.

The platen 11 may be rotated by finger-wheels 17 on the platen-shaft 12 or by usual line-spacing mechanism (not shown). For gaging a workpiece to typing position on the platen 11, use may be made of a pair of wingscales 18, one of which is shown in Figure 1. The parts described above may be constructed the same as they are in a standard Underwood typewriting machine.

The check-protecting mechanism of my device may include a right and a left mounting bracket 20 and 21, respectively, each having an outturned horizontal flange 22 resting on usual outturned flanges 23 of the end plates 13 and fastened .thereto by screws 24. Each of the brackets 20 and 21 has an inreaching flange 25 which is provided with a row of tapped mounting holes 26, each hole in one flange having a paired relation with an opposite hole in the other flange.

A strong U-shaped metal cross-bar extends between the flanges 25 to which it is rigidly fastened by screws 31 which pass through suitable holes provided in each end of the bar 30 and engage in a selected pair of the tapped holes 26. To permit a base portion 32 of the cross-bar 30 to fit squarely against the flanges 25 and give greater rigidity to the mounting of the cross-bar on the flanges, a-short portion of transverse integral flange element 33 of the cross-bar at each end thereof'is cut away, as Sllf. wn in Figure 1. The front face of the cross-bar 30, as mounted in the typewriter, has formed therein a row of die teeth or serrations 34 for shredding or macerating the portion of the bank-check slip on which the amount of the check is written in words.

A second die 35 has integral teeth formed for co-operating with the teeth 34, and means for moving the second die into shredded engagement with the teeth include upper and lower angle members 36 and 37 positioned adjacent each end of the cross-bar 30 and fastened to it by screws 38 which pass through holes in arms 40 and 41 of the angle members 36 and 37, respectively, to engage in tapped holes 39 in the flange elements 33.

Each tapped hole 39 in one flange 33 has a paired relation with a tapped hole 39 in the other flange 33, and a plurality of pairs of the holes 39 may be provided for a purpose to appear here inaftcr. To more securely fasten the angle mem ber 36 to the flange-element 33, an integral flangemember 42 of the arm 40 may engage tightly against the outer end of its adjoining flangeelement 33.

Angle-members 36 and 3'7 include arms 43 and 44. respectively, whose forward faces are disposed in a rearwardly-inclined plane. To these faces may be secured, as by rivets 45. right and left separated plate-members 46 and 47, respectively, which form a paper-table, generally designated as 48, for a check-sheet 49 advancing from the platen 11. Each plate 46 and 47 has a middle section cut away to leave the teeth 34 exposed for engagement with a check-sheet lying on the table 48. The plate-members 46 and 47 have in tegral forwardly-bent flange-portions 50 and 51, respectively, each of which terminates in a mounting lug 52, each lug being substantially disposed opposite the teeth 34. The flange-portions serve as side-edge gages for the check-sheet advancing up from the typewriting machine to shredding position between the dies 34 and 35. Aligned holes are provided in the lugs 52 for receiving reduced axle-members 53 of pressure roller 54 eccentrically mounted on the axle-members 53.

A handle 55 has a hub 56 for engaging a protrusion of the axle-member 53 extending past the right-hand lug 52, whereby the handle is disposed for operating the roller 54. To hold the roller in released position, a spring 57 is coiled about the hub 56 and has one end hooked about the handle 55, and the other end about a pin 58 fastened in the adjacent lug 52.

To mount the die 35 so that it may be normally disposed opposite the die-teeth Men the opposite side therefrom of the path of the check-sheet 49 and near enough to be easily moved into engagement with the die-teeth 34, is a feature of the present invention. In carrying out this feature, the die 35 may be made from a steel bar having a cross-section of a trapezoid, the narrower one of its two parallel faces being disposed adjacent the die-teeth 34.. A strip of metal-plate 59 is crimped about the forward converging sides of the die, which fasten the plate securely to the die. Adjacent each end of the die an integral portion 60 of the plate is left fiat in an uncrimped condition for extending downwardly to have fastened thereto, as by riveting, a short strip 61 of a resilient metal like spring steel. The lower end portion of each strip 61 is fastened by a screw 62 to an inreaching portion 63 of a forwardly-extending lug 64, which is integrally joined to the flange-member 52. To more securely fasten the resilient strip 61 to the inreaching lug-portion 63, a lower end portion 65 of each strip is bent at right angles thereto for engaging against the lower edge of the lug-portion 63.

The arrangement of the parts supporting the die 35 is such that the spring-strips 61 areinitial- 1y stressed so as to normally urge the upper face of the strip 59, which is crimped over the die 35, against the roller 54 with a uniform pressure throughout the lengthof the roller. By simply pulling the handle 55 downwardly from the Figure 1 to the Figure 2 position, the die 35 is moved rearward with sufficient strong pressure to shred and macerate a check-slip between it and the relatively fixed die-teeth 34. It will be noted by the above-described construction, that pressure onthe die is applied uniformly over all its workface which is desirable for securing uniform shredding results.

It is usual to print part of the data appearing on a check or check-slip 70, which may be of usual form, such as is illustrated in Figure 4. Among the other data usually printed is the word Dollars, which is commonly positioned near the right edge of the check-slip and aligned with the usual space which is provided at the left for hearing the typed or written words which state the amount of the check.

For economy of labor in printing checks and for convenience thereafter in feeding them into a typewriting machine, a succession of like checks 70 are often printed on a sheet, one adjoining another, being usually separated by weakened or perforated dividing lines '71. Such a series of checks integrally joined, the top edge of one to the bottom edge of the preceding check, constitutes a check-sheet, such as the checksheet 49. By this arrangement, the amountbearing spaces on the several checks, each disposed opposite the word Dollars, are spaced equal distances apart along the path of the check-sheet, as it advances from the typewriting machine to the check-protecting mechanism.

Advantage is taken in the presentinvention of the uniform spacing of the amount-bearing spaces of the checks on the check-sheet 49, whereby the need for gaging a typed check-strip 70 to shredding position is eliminated. This desirable resultis accomplished by mounting the check-protecting mechanism on the platenframe 14, so as to position the work-field of themechanism, as determined by engagement of the teeth 34 and the die 35, a distance from the printing line of the platen, measured alongthe path of the check-sheet 49, equal to the distance between two amount-bearing spaces of two adjoiningattached checks '70 when the amountbearing' space of one of the checks is in the printing field of the typewriting machine, and the other check is advanced beyond the platen 11 at the delivery side thereof.

Thus, when one check '70 is gaged by means, such as the wing-scales 18, to position it in the typewriting machine for having its amount .in words typed in the space provided therefor, the next preceding check (already typed) is simultaneously-disposed in shreddingposition between the dieteeth 34 and the die 35. The typed check is shredded preferably just after or before the amount in words is typed on the next following check whose amount-bearing space is then in the printing field. After a typed check has been shredded and the handle 55 released, the check is left in position to have its trailing edge advanced to tearing-off position ,(see Figure 3) slightly above the top edges of the plate-members 46 and 47 upon advancing the next unprotected check to shredding position.

It will be.

of the platen 11. This arrangement permits a check-sheet 49, a record-sheet 7'7 and a carbonsheet '78, overlying the record-sheet 77, to be inserted together around the platen 11 and permits the check-sheet 49 to be passed over the table 48 and between the die-teeth 34 and the die 35, while the record-sheet and the overlying carbon-sheet are passed beneath the extremities 75 and '76 and under two usual pressure-rollers 79, which engage against the upper side of the platen 11.

By this construction, a record can be easily made of checks while they are typed and protected in a device embodying my invention. Moreover, the record-sheet '77 and carbon-sheet '78, after passing beneath the extremities 75 and 76, are safe against being caught between the die-teeth 34 and the die 35 and damaged.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
