METHOD OF MAKING- A DIE.

Specification of Letters Patent.

Patented Nov. 22, 1921.

Application filed April 29, 1919, Serial No. 293,527. Renewed October 11, 1921. Serial No. 507,158.

To all whom it may concern Be it known that I, ALBERT A. MOINTYRE,

a citizen of the United States, residing at Bonners Ferry, in the county of Boundary and State of Idaho, have invented new and useful Improvements in Methods of Making a Die, of which the following is a specification.

The object of this invention is to provide a device for the synthetic and analytic study of a complete entityby segregation and combination of the partsof such entity.

In the more specific form of my invention the same is applied to the study of geography, and will be so illustrated, the device presenting, when united, an integral or complete political entity which is sub-divided so that it can be segregated into predetermined and definite integers.

More specifically speaking, my invention has to do with an improved method whereby a previously printed and completed map,

for instance, may be subsequently severed or sub-divided into its various counties, if the map is of a State, or into its component States, if the map is of a country. In this connection, sub-divided maps have heretofore been made at great expense owing to the necessity for individual hand work in their production, as regards the severance of the entity into its integers.

In accordance with my improved method, an imprint of the exact configuration of the map or entity is made upon a block of which an improved die is afterward made. This block is sub-divided on the exact lines of the configuration impressed thereon, and in the kerfs of the saw or other sub-dividing tool are disposed cutting ruling means. The cutting ruling means project in relief from that face of the block or die which presents the configuration in the negative form. Therefore, when this cutting die is brought into sub-dividing impression engagement with the previously printed map, in positive facing relation toward the die, the die will sever the map into its component integers precisely on the lines of configuration division of the map. Thus, by a mechanical and rapid method I am enabled to very rapidly and accurately produce sub-dividedentities which heretofore have been altogether too costly to in any way figure as a large and cheap volume product.

As'a mechanism, my invention comprises is cutting die having impressed on one. face thereof the configuration of the finished printed matter to be sub-divided, the die being severed on the lines of the configuration and having cutting ruling means interposed in the kerfs of the saw or other severing implement.

My invention has other features and objects which will be more fully described in connection with the accompanying drawings and which will be more particularly pointed out in and by the appendedclaims.

In the drawings Figure 1 is a face view of an engraved plate, in negative, on which the configuration of the map appears, itbeing assumed that this plate is on the bed of a platen press..

Fig. 2 is a contracted view of a tympan on in Fig. 1.

Fig. 5 is a face view of the block after it has been sub-divided and equipped with its cutting rule means and clamped in a chase.

Fig. 6 is a sectional view on line 6-6 of Fig. 5.

Fig. 7 product.

Fig. .8 is an edge view thereof.

Like characters of reference designate similar parts throughout-the different figures of the drawings.

My improved method may be carried out in at least two different ways. The engraved plate 1, having on its face the configuration of the map to be printed, as indicated at 2, may be secured to the bed of a platen press. A tympan 3, on the platen,

is a face view of the sub-divided the plate 1. Preferably, two or three impressions will be made on the tympan not only'for the purpose of getting a clear and continuous line impression but also for the purpose of getting enough ink on the tympan to makean unbroken offset impression therefrom. The plate is then removed from the may serve to take an inked impression from bed and an integral wood or like block 4 is was r the a @fiset er save is then transferred from the tympan to the woodblock 4:, as indicated by the lines in Fig. 3. Now it will be seen that the nega-.

tive impression from the plate 1 will have been transferred to the tympan, in positive form, and the offset impression will have been transferred back to the block in negative form. T he block 4: is then severed on lines 2 thereby sub-dividing the same into counties indicated by lines 2. Instead of giving the counties names, I will represent H @779 C b 77,, 0 777 (C d 77, C e 797 (4 ;77,' 4C 77 i V The hack-saw or other implement used to sub-divide the: block t will leave a horror kerfs, as clearly indicated" at 5,.in"th'e-finished product, these kerf faces being unnecessary to illustrate-in Fig. 4. Iinterp'ose in these kerfs ruling elements 6, similar-elements 7 bordering the edges of the block. These ruling elements or strips may either be bent initially to fit the configuration of the lrerfs, or,-when the sub-divided block is clamped in the chase 6, the elements be shaped to form. However, in any event,

the ruling elements or membersare necessarily made of thin metal which can readily be shaped to the necessary form and I do not wish to be limited to any specific man-;

ner of so doing although I consider it a novel feature to shape these ruling elements,

broadly. These ruling elements are prefer ablyo'f a width slightly'in excess of the thickness of the block so that their edges 8 will project in relief from'one'faceof the block. These projecting edges are sharpened.

to form kniteor'cutting edges as will be clearly seen by'reierenceto Fig; 6. Now it will be clear that as far as the block is con cerned it does not make any difference on which face thereof the printed impression is made. In any event, when the block is in use for sub-dividing previously printed maps, in positive, that face or the block which will be considered face 9 will be presented to the entity torbe sub-divided, and face 9 will present the configuration in negative form. Therefore while'the ink impression or transfer mighthave' been made on face 10 of the block, it will be a simple matter todispose the ruling elements so 7 ct 1nre list from the opposite race.

If desired, a direct impression from plate 1 may be made on the block, in thefirst in-- stance, by fixing the block on the platen of the press. Either way, is clearly within the purvlew of my invention.

Taking a simple method o1 describing the operation, it will be assumed'that the plate 1 is disposed on the; bed of a platen press and that a number of the desired quantityof cards 11 haye been printed withthe map as-engraved onthe-plate; Thus is" will be assumed that one" thousand" ma'pfi cards 11 Either before or after this printing operation, my improved die will have been made up and clamped into a chase, as shown in Fig. 5. the platel is taken out of the press and the structure shown in 5 is substituted, therefor on the bed. These printed cards are then taken one by one, in the usual manher, and fed into place on the gages of the platen. the press operates, the cutting ruling edges of the die will. be brought into impression engagement with the printed cards and will subdivide them as indicated at 5. The cutting edgesof the ruling elements will necessarily register accurately with the lines on the previously printed map by reas'onot the fact that the guiding lines of severance for subdividing the block constituted theimpres'sion from the very plate which printed the maps. Now if the cards ll were completely subdivided, considerable difiiculty would be encountered in removing the integers from the platen. Therefore, certainof the cutting edges of the rule'ele ments are interrupted, as indicated at 12, in Fig. 6. By this means, the integers of the" map will be completelysevered except for those minute junctures formed or left by the slight interruptions 12. Thus the substantially completely subdivided integers'can be bodily removed from the platen with the same facility as the'integral card was inserte'd thereon. r r V w In some instances. the card when'being printed will be slightly larger, relatively speaking, than that shown in Fig. 3, in which event the bordering cutting rules? would cut the edges of thecard'to size. By means of the device and method in vention herein disclosed I have proven that After the cards'have dried, then s.

integers or complete entity may be segre- V eneral public at a very ing nature in the putting'together and talr in'g apart of the subdivided integers. V

It is believed that the novelty and utility of my invention will be fully understoodfromthe foregoing description, and while I have herein shown and described different species of the genus, I do not; wish to be limited theretoexcept for such limitations asthe claimsm'ayimport; v r

I claim- 1. The herein-described method of making a die for the subdivision of integers of an entity, Which consists, in making on a die stock or block an impression from the engraved or other printing plate in exact facsimile of the configuration of the entity and its integers to be printed, in subdividing the block on the lines of such configuration, and in interposing cutting rules in suchlines of division of the block With the cutting edges of said rules in relief from the cutting or impression side of the block.

2. The herein-described method of making a die for subdividing the integers of an entity, which consists, in transferring upon a die block a line impression of such entity, in subdividing the block into integers on the lines of such impression, in interposing cuttingrules in the lines of such subdivision, and in applying pressure to the divided block integers to shape the rules to said lines of division. s In testimony that I claim the foregoing as my own, I hereby afiix my signature. ALBERT A. MoINTYRE.
