' OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
PRINTING DEVICE AND METHOD OF MAKING.
Specification of Letters Patent.
Patented Dec. 2 t, 1912.
To all whom it may concern:
Be it known that l, Josnru S. Duncan, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful llnprovements in Printing Devices and Methods of Making, of which the following is a specification.
This invention relates to printing devices and'method of making the same, and aims to produce from a sheet metal blank a printing device on which the printing characters will be stamped up in relief on one side of the blank and will be located more closely together than it has heretofore been possible to make them.
My invention will be best understood by reference to the following description when considered in connection with the accompanying drawings illustrating a printing device made in accordance withmy invention vand one set of dies employed in its formation.
Referring to the drawings E-Figur 1 is a fragmentary side elevation of a printing device provided with a plurality of printing characters and showingthe dies employed in forming the characters; Fig. 2 is a longitudinal sectional View taken substantially on the line 2-2 of Fig. 3; Fig. 3 is a transverse sectional view taken substantially 0n the line 3--3 of Fig. 2; Fig. 4 is a-fragmentary longitudinal sectional view of my improved printing device, the scction eing taken between the lines of printing characters; Figs. 5 and 6 are perspective views of a punch and die respectively employed in forming my improved printing device; and Fig. 7 is a side view of the die shown in Fig. 6.
Prior to my present invention the printing characters on sheet metal printing devices have been formed independently of each other by stamping them up directly to the required height from a metal blank by means of punches and dies, but the individ ual characters in each line heretofore have been spaced some little distance apart. It is very desirable in some classes of printing that the individual printing characters in the lines be located closely together and my present invention has for its p imary object the p'roduction of a printing device on which the individual printing characters will be arranged more closely together than it has heretofore been possible to form them.
From the drawings it will be observed that in carrying out my improved method I employ a die 10 codperating with a punch 11 to-produce my novel printing device having the printing characters arranged thereon very closely together. The punch 11 is provided at its operating end with a suitable elevated character-forming portion 12, the outer walls of which taper toward the body of the punch as indicated at 13 and merge at their bases into a flat portion 15 which forms a flat shoulder or ledge surrounding the charactcr-f0rming portion. The die 10 is provided on its face with a depression or recess 16 conforming in shape to the chameter-forming portion 12 of the punch and adapted to codperatc. therewith to form the desired printing character. At the top and bottom of the character-forming depression 16 the walls of the die are extended outwardly as indicated at 17 to produce lips which retain the metal at the top and bottom of the character beii g formed in its original plane as shown in' l ig. 3. The walls of the die at the sides of the character forming depression however are removed or, in other words, dcprcssed relatively to the end lips 17 as indicated by reference charac terlS, so that the metal between the adjacent individual printing charactcrs on a printing device is permitted to become distorted from its original plane and assume an elevated position relatively to the metal at the top and bottom of the character as shown in Fig. 2.
In the present instance I have shown, for purposes of illustration merely, a punch and die each adapted to produce the letter O and the completed characters are indicated on the drawings by reference numeral 19. It will be obvious, however, that any desired letter,- figure or other character can be formed on a sheet metal blank by the use of punches and dies constructed as above described but bearing a character forming portion of the desired shape and a corresponding depression.
In carrying out my im roved method a sheet-metal blank upon w ich the printing characters are to be produced is fed between the unch and die above described,
the blank eing fed forward the requisite distance after the formation of each character. As the punch and die are forced together the printing character is stamped up from the metal as shown in Figs. 2 and 3. During the stamping up operation the metal at the top and bottom of the characters being formed is held in its original plane by the lips 17 on the die which press the metal against the ledge or shoulder 15 onthe punch. The side walls 18 of the die being shorter than the lips or ends 1'? permit the metal at the sides of the character being formed to be distorted by the punch from its original plane, the metal between the letters at the point indicated by reference character 20 being, as will be observed from an in- .spection of Fig. 2, elevated relatively to the metal at the top and'bottom of the character. Since the metal could not be readily stretched in both directions from a point intermediate the adjacent printing characters sufficiently to form both characters if the metal at this point were retained in its original plane, it will be obvious that by distorting the metal at this point or, in other words, raising it from its original plane as the printing characters are being formed the tension upon the metal is considerably decreased with the result that the characters may be formed very closely together without tearing or unduly stretching the metal at the sides of the characters. "Heretofore it has not been possible to stamp up printing characters on a metal blank closer together thaneight to the 111011 but bymy improved method the characters may be formed nine or even ten to the inch so that the impressions made thereby are spaced similarly to and very closely re- I semble typewritten matter.-
It is believed that my invention will be understood from the foregoing without further description and it will be manifest to those skilled in the art that the invention is capable of considerable variation without departing from the spirit or sacrificing any of the material advantages thereof.
I claim:
1. The method of producing a printing device, which consists in punchin a sheet metal blank from the back thereo to form a printing character projecting at the front of theblank and by the same punching act displacing the metal of the blank at the side of and contiguous to the character toward the front of the blank.
2. The method of producing a printing device which consists in punching a sheet metal blank from the back thereof to form a printing character projecting at the front of the blank, displacing the metal at the side of and contiguous to the character from the plane of the blank, and holding the metal of the blank in the plane of the blank at the top and bottom of the printing character.
3. The method of producing a printing printing character projecting at the front of the blank and adjacent the first mentioned character, and further displacing the metal between the characters which was displaced in punching the first character to lie between the plane of the blank and the plane of the printing faces of the characters.
4. The method of producing a printing devicewhich consists in punching asheet metal blank from the back thereof to form a printing character projecting at the front of the blank, and by the same punching act displacing the metal of the blank at opposite sides of and contiguous to the character toward the front of the-blank.
5. A-printing device comprising a sheet metal blank having a printing character punched up from the back thereof and prbjecting at the front of the blank, the metal at opposite sides of the character and contiguous thereto being displaced from the plane of that portion of the blank from which the character is struck up and lying between said portion of the blank and the 1 plane of the printing face of the character. 6. A sheet-metal printing device having a plurality of lines of printing characters of the device extending along and beneath the line of characters.
7. A printing device comprising a sheet metal blank having a printing character stamped up from the back thereof and projecting atthe front of the blank, the metal at opposite sides of the character and contiguous thereto being displaced from the plane of the blank and lying between the plane of the blank and the plane of the printing face of the character, and the metal at the top and bottom of the printing character being in the plane of the blank.
8. A printing device comprising a sheet metal blank having a line of printing char-' acters stamped up from the back thereof and projecting at the front. of the blank, the metal between adjacent characters being displaced from the plane of that portion of the blank from which the line of printing characters is struck up and lying between said portion of the blank and the plane of the printing faces of the printing characters.
