Specification of Letters Patent.

Patented-dune 24:, 1919.

Original application filed May 10, 1911, Serial No. 626,302. Divided and this application led Apri128, 1917.

. Serial No. 165,Q10. Y.

the United States, and a resident of Boston, .i in the -county of Suffolk and State of Massa, ehusetts,) invented a new and useful lmprovement in Printing Apparatus, of which the following is a specification.

This application is a dli'ision of the application of Edwin E. Angell, Serial No. 626,302, filed May 10, 1911, which issued as Patent No. 1,282,166, October 22, 1918, for method of protectingcommercial paper.

One object of this invention is to provide 4a printing apparatus for marking checks, bonds and. other commercial papers with an inked impression of the value thereof, or other indicia., so constructed as to emboss or disrupt the iibers of the paper over the area to which the ink is applied, so that the paper. will become impregnated with the ink and thus indelibly marked with the desired inscription. K

A This and other objects and advantages are fully explained in the following detailed description of one embodimentI of the invention which is illustrated in the accompanying drawings, in which- Figure l represents a longitudinal sectional elevation olf the apparatus.

Fig. 2 is a plan view of a part of a check or other commercial paper bearing symbols 'representing value applied according to the invention.

Fig. 3- is a View of one of these symbols on`an enlarged scale.

Fig. 4t is a cross-sectional view of that part of the paper bearing the symbol shown in Fig 3, taken on the line Llof said figure, but representing the same on an enlarged scale.

Fig. 5 shows one of the types by which y the symbols are applied.

Fig. 6 shows the bed against which the paper is pressed by the type and by which the perforations between the deposits of ink made by the type are made. This invention., in its present embodiment, is used in conjunction with an apparatus disclosed in the United States Letters Patentto Angell, No. 936,398, granted October 12, 1909, which apparatus will now be described, but, it is to be understood that the present invention is susceptible of employment in a wide variety of applications and is in no wise limited to use with the particular apparatus oi' the above Patent No. 936,398.

In the machine, l represents a table upon which the check or other paper representedl by 2 is laid when being stamped. Over the table is mounted a type Wheel 3 having a number oi'types l, which wheel is carried by -a shaft 5 journaledin bearings 6, 7, in an its pivot 9, thereby raising the type wheel I and allowing the paper to be placed under it. By turning the handle about the axis oi shaft `5, the type wheel, which is connected to said shaft, may be placed so that anyone ot the types 4 may come into posi tion for impressing the paper. lll/'hen the paper is engaged by the type, it is pressed by the latter against bed 13,-shown in dotted lines in Fig. l, and in detail vin Fig. 6, set into the table and by the latter indented or punctured. The superiicial area of the bed is equal to, or perhaps slightly greater than that of any one of the types, so that it acts upon the entire area 4of paper acted upon by paper from the type.

'spots or dots of ink, and when not inked,

` depress-minute areas of the paper. .Preferl invention above suggested, where the'projections 14 are arranged in the form of a ably the projections are formedl by making two sets of parallel grooves in the faceof the marking die, the grooves 15 of one 'set being transverse and preferably perpendicular to thoseL of the other set 16. Such grooves are suiiiciently narrow and` spaced so far apart, that the -ends of the intermediate projections have area enough to leave deposits of ink of material size. -In the particular embodiment of the inventionhere r illustrated, thjnnumber or other conventional symbol is for ed on the paper by leaving a blank spac of the paper surroundedy on all sides by the dots. Accordingly to produce this result the type is provided with a recess having the outlines of the figure, but

' reversed, as indicated in Fig- 5. Itis within the contemplation of the inventlon, and

would not be a departure therefrom to arrange the projections 14 in the reversed form of the symbol, thereby printing the symbol in the form of a collection of dots arranged in the form of the symbol. T-hat is, the marking member `would be provided with a raised portion corresponding to an ordinary printing type, but cut across its face by intersecting grooves.

The bed 13, against which the paper 1s pressed by the printing member, has its'face cut by intersecting grooves 17 and 18 which are spaced equally and aline parallel to the corresponding grooves 15 and 16 of the printin member. The groovesA are of such width, owever, as to reduce the ends of the projections leftbetween them to comparatively sharp points 19. The bed is so placed on the machine with reference to the printing members that the rows of points on the bed will enter the grooves 15 and 16 of the die when the latter is pressed toward the bed and will thus puncture the' paper at the in? tersections of the blank lines between the dots thereon. Thus the points mutilate. the

aper between the areas upon which ink is deposited and in so doing raise burs upon the face of the paper which flank the inked areas and prevent erasure of the ink thereon.

The effect on the paper is illustrated .in Figs. 3 and 4, from which it will be seen that there is a plain area 20 in outline correspending to the symbol surrounded on all sides by isolated small depressed areas 2l upon which are' deposits of ink, and between which are sharply raised and perforated projections 22. In the embodiment ofthe symbol, the effect upon the-paper is to produce a number of inked depressions and per- .face two'sets of parallel grooves, of whici the grooves of one set intersect those of the other set, forming isolated iiat topped printing projections.

.2. In a machine of the class described, the

combination with a set of type forms each having its face cut.` y shallow intersecting grooves to divide said face into a plurality of pyramidal frusta, of a--platen having its impression surface cut by intersecting grooves deep enough to form a plurality of pyramidal points relatively spaced to register with the intersections of the grooves in .the type forms, and means for establishing coperative'relationship between said platen and any desired type form. l

3. In a machine of the class described, the combination with an adjustable type carrier provided Awith type forms each of which has its face cut by shallow intersecting grooves to divide said face into a plurality of flat faced ink receiving surfaces, of a platen having its impression face cut by intersecting grooves deep enough to form a 'plurality of pyramidal points relatively positioned to register with the intersections of the grooves in the type form, means for adjusting the type carrier to position any desired type form opposite the platen, and means for applying ink to the ink receiving surfaces on the tyIfpe forms.

4. n a machine of the class described, the

combination with an adjustable type carrier which has to register' with the intersections' of `the grooves in the type forms, means for applying ink to the aforesaid flat faced pro'jections, and means for adjusting the type carrier to position any site tlieplaten.

InaI machine o'f the class described, the combination with an 'adjustable type carrier provided with rectangular type forms having-'their faces recessed to form characters and the unrecessed portionsetherleof cut by shallow intersecting groovesI to form a pluralityfof fiat faced projections,of a platenhaving its impression face cut by intersectdesired type form oppomomes@ ing grooves deep eriough, to form sharp a distance eque] to the Width of he type pomts relative? plositioned to reglter the form printed from. intersections o t o grooves in t e ivy e i Y A ,f forms, means lfor applying ink to thel afolpe- Ad l. .lt 1 Ed E'TQYQ ,Z said Het faced projections, means for adjustmm .7 a ma of wm nge 'b am?? ing the type carrier to position any desired Witnesses: type form opposite the platen, and Work Gnosvmo CALKINS, feeding devices construct-ed to feed the work HELEN M.
