PRINTING-DIE.

Specification of Letters Patent.

Patented Feb. a, rat.

a lication filed March 110, 1917. Serial in. 153,862.

To all whom it may concern:

Be it known that I, HERMAN C. Wnnrnn, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented a new and Improved Printing-Die, of which the following is a specification.

My invention, while relating to check protecting devices in general, has more especial reference to check writers and is an improvement over the invention for which Letters Patent No. 1.174.642 was granted to me under date of March 7, 1916.

In machines of this class there have been provided various ways of having the cooperating printing members npt only print certain selected words or chhr 'acters 'on a check. or other negotiable instrument, but in so doing to break the paper throughout the printed surface in a manner that ink from the type will be absorbed by the disrupted fibers, the purpose of such mutilation being to prevent erasure for fraudulently raising the amount made payable.

I-Ieretofore, the construction and operation of the printing mechanism has usually been such that ink is applied to the face only of the check. It is the object of this invention, however, to provide aplaten or die member which, when in operative engagement with the type, efl'ects both a disruption of the fibers throughout the printed surface and an inking of the impressed characters on both the face and reverse sides of the check; and a further object is to form the platen in a manner that it can not cause injury to 'the type characters, especially their cutting edges.

Another object of the invention is to make use of a sub-inking pad su ported by the die member so that ink Wlll be supplied thereto from the type characters when breaking through the paper during the printing operation.

In the accomplishment of my invention, I make use of a channeled bar for receiving a sub-inking ad and this channel is covered by a grld formed by a plurality of equally spaced parallel wires rigidly secured to the bar by a common retaining member. The type characters are carried on a support movable relatively toward and from the die and are grooved in the usual way to form parallel ridges which eng fe through the openings between the Wires of the grid, the channeled bar being adjustably supported so that thcre'will be proper registration of the wires with the alternating ridges and grooves of the type.

The sub-inking pad engages the under slde of the grid and the portions of the impressed characters forced between the wires contact with-the pad and cause the paper to be inked on the under and embossed side whlle the impressions made on the face side are inked from the type. Ink is supplied to the type by any suitable means which, when the support therefor comprises a type cylinder, is usually one or more ink rollers removably held in yielding contact therewith. The pad is suitably inked before being inserted to place but cannot become dry as suflicient ink to keep it in proper condition is supplied from the ridges of the type characters which contact therewith when cutting through the paper of the instrument being printed.

The invention will first be described and will then be particularly defined in the appended claims.

The accompanying drawings illustrating my invention are as follows Figure 1 is a side elevation of a check writing machine in which the invention is adapted to be used; Fig 2, is a fragmentary portion of the type support showing in plan view part of a line of type characters; Figs. 3 and 4, the appearance of the face and reverse sides, respectively, of a check when printed; Fig. 5, a plan view of the die member and portion of the machine base in which it is supported; Fig. 6, a longitudinal sectional view taken along the line 6-6 of Fig. 5; Fig. 7, a transverse sectional view taken along the line 77 of Fig. 5; Fig. 8, a longitudinal sectional view of a portion of the die with type characters in engagement therewith; and Fig. 9, a fragmentary portion in side view of the channeled bar showing the grooves for receiving the grid forming wires. Figs. 2 to 7, inclusive, are drawn to a scale approximately three times the actual size of the parts shown and Figs. 8 and 9 to a still larger scale.

Similar reference characters refer to similar parts throughout the several views.

Referring first to Fig. 1.

The numeral 1 represents the base and a v the head of a check writing machine of the character for which the invention is more especially intended, the front portion of the head being spaced apart from the base to receive a check 3 therebetween which is supported on the base cover plate 4. In this machine the type bars 5 extend longitudinally of and are .carried on the periphery of a cylinder 8 revolubly supported in bearings 9 slidable in vertical extending guideways 10 in the side walls of the head member 2. This cylinder may be turned to bring any predetermined line of type directly above' the platen or die 11 supported in' the member 12, forming an integral part of the base 1, and it is raised and lowered by the levers 13 and 14 on actuation of the operating lever 15. At 16 are seen the usual ink rollers mounted in suitable supporting arms 17 and held in yielding engagement with the cylinder 8 for supplying ink to the characters on the several type bars.

The die member complete is referred to by the numeral 11 and comprises a channeled bar 18, sub-inking pad 19, grid 20 and retaming/member 21. The bar 18 in length and wldth is slightly greater than the corresponding dimensions of the type bars 5, and has its upper face cut away to form side walls 22 with a longitudinally extending channel therebetween. These side Walls are slotted transversely at 23 (Fig. 9) to receive and prevent lateral movement of -the equally spaced parallel wires which extend across the channel and form the grid 20. The ends of the wires are turned down against the outer faces of the side walls 22 and-are held to place by a common retaining member comprising the plate 21 having an opening adapting it to engage thereover. This plate is seated on shoulders formed at the ends of the bar 18 and is held against removal by ears 24 bent outwardly from the ends of the side walls 22. The ink pad 19 is contained within the channel formed in the bar 18 and is substantially the same in thickness as the depth of the channel so as to engage the under face of the grid 20.

The die 11 is supported by the base member 12 in a longitudinally extending channel 26 and any preferred means for adjusting the die both longitudinally and vertically may be provided as, for instance, that shown in the drawings wherein 25 is a screw threaded into one end of the bar 18, such screw having a shoulder 27 engaging in a transverse slot 28 in the support 12, whereby turning the screw causes a longitudinal movement of the die; and a vertical adjustment is provided for by the screws 29 ex tending upwardly through the support 12 and engaging the bottom of the bar 18,

-While the die is normally held against displacement by the centrally disposed screw 30 extending vertically through an enlarged opening 31 in the support 12 and threaded into the bar 18.

The impressin members are type characters made, pre erably, of hard metal with the face thereof serrated, as'will hereinafter be described, or of a comparatively soft composition into which the impressions of the wires forming the grid will be made by contact therewith under suflicient pressure, the function of the type being to both print on the face of the paper and to force portions thereof through the openings in the grid and into contact with the ink pad there- \under, the result bein the inking of the impressed characters on 0th sides of the paper.

The type characters 32 shown in the drawings'are formed on bars 5 extending longitudinally of the cylinder 8 and cast integrally on its periphery. Parallel grooves are formed in the type of a depth less that. the thickness of the bars above the surface of the cylinder and so angularly disposed as to register with the wires forming the grid. Thus it will be seen that the type characters have ridges alternating with the grooves and it is preferable that these ridges be formed with sharp cutting edges.

In machines where the type characters and the platen or die have correspondingly formed ridges and grooves, the ridges of one or the other are often broken and their cutting edges dulled if one of such members gets slightly out of alinement; but with a die made in accordance with my invention the ridges of the type characters engage in the open and bottomless spaces between the wires of the grid and cannot become injured nor their edges dulled other than by contact with the material of the instruments printed.

When employing my invention, the cooperation of the type and sub-inking die will be such as to impress the characters in the paper in a manner to break the fibers, and, also, to ink the characters on both the face and reverse sides of the paper, as shown in Figs. 3 and 4, respectively. The pad will be suitably inked before inserted to place but will not at any time become dry as suliicient ink will be supplied thereto from the edges of the type characters on cutting or breaking through the paper during the printing operation.
