Automatic milling-machine
|
Ottmar Mergenthaler |
Baltimore, MD |
This milling machine is a design "wherein blanks are store in a magazine..." This machine "is shown and described herein as employed in connection with the manufacture of matrices for use in linotype machines..." The matrices are the pieces of metal that each have one character on an end. |

Machine for straightening metal stock
|
Ottmar Mergenthaler |
Baltimore, MD |
Straightening machines pass metal bar stock between a pair of rollers to remove irregularities such as bends and wrinkles. The pressure required normally leads to the use of larger diameter rolls, but larger rolls are less effective at removing short bends or wrinkles. In this patent, Mergenthaler proposes smaller-diameter roles with substantially journalling (bearing surfaces) to minimize deflection.
Mergenthaler invented the linotype machine, and this particular patent is one of a series granted just a couple of weeks after the inventor's death from tuberculosis. Presumably this metal straightening machine is in some way relevant to the linotype process, perhaps for the processing of brass bar stock that will be turned into "matrices", the strips of brass that each have the female image of a character on one end and that are assembled by the linotype machine into lines used to cast a line of type. |

Punching-press
|
Ottmar Mergenthaler |
Baltimore, MD |
"My invention relates to punching-presses, and particularly to that form of punching-press wherein the blanks are fed one by one in such manner as to be brought under the reciprocating die...as employed in connection with the manufacture of matrices for use in linotype-machines..." |

Universal milling-machine
|
Ottmar Mergenthaler |
Baltimore, MD |
The inventor is well remembered today as the inventor of the linotype machine, a very important innovation in printing, especially for newspapers and magazines. The idea of casting a line of type by assembling a line of female letter-molds was wholly his idea and he spent several years designing and refining the machine before he introduced it to the market, to great success. Mergenthaler died young of tuberculosis, just a couple of weeks before this patent was issued.
The Ott. Mergenthaler manufactured milling machines for a few years, and then dropped that business in favor of making adjustable reamers, milling cutters, and taps. The Linotype business had been sold to a separate entity, the Mergenthaler Linotype Co. of Brooklyn.
This milling machine is a universal design "which are capable of general or universal work in which the various cutters or milling-tools may be arranged to act in various positions and at a variety of angles." Such machines were already well known but early universal machines were overly complex and, in allowing the milling head to be angularly adjusted, sacrificed rigidity. This patent covers the universal milling machine that was sold by the Ott. Mergenthaler Co. On this same date Mergenthaler was granted several other patents, including for milling machines, but all of those patents are specialized for the production of the "matrices" used in the linotype machines. |

Automatic milling-machine
|
Ottmar Mergenthaler |
Baltimore, MD |
This milling machine is adapted to "operate upon a series of blanks...it is shown and described herein as employed in connection with the manufacture of matrices for use in linotype-machines..." In short, this machine is specialized for making the brass "matrices" that each have the female image of one letter on its end. |

Stamping-press
|
Ottmar Mergenthaler |
Baltimore, MD |
"My invention relates to stamping-presses, and particularly to that class of stamping-presses in which the blanks to be operated upon are stored in a magazine, from which they are fed one by one to reciprocating dies...as employed in connection with the manufacture of matrices for linotype-machines..." |

Automatic milling-machine
|
Ottmar Mergenthaler |
Baltimore, MD |
This milling machine is adapted to "act upon the two opposite sides of the work in a single operation...it is shown and described herein as employed in connection with the manufacture of matrices for use in linotype-machines..." In short, this machine is specialized for making the brass "matrices" that each have the female image of one letter on its end. |

Automatic milling-machine
|
Ottmar Mergenthaler |
Baltimore, MD |
"My invention relates to automatic milling-machines, and especially to that class of milling-machines wherein blanks are stored in a magazine...In the present machine...I employ a rotatable annular magazine suitably actuated and adapted to receive and contain blanks which, because of projecting portions, as hereinafter described, are not capable of being stored one upon another and accurately and readily delivered one at a time." The machine is particularly "for the manufacture of matrices for use in linotype-machines". |

Boring-tool
|
John F. Cadell |
Baltimore, MD |
"My invention relates to tools for boring holes in metal plates, and particularly for boring boiler-plates to receive the tubes." This seems like a strange invention to be assigned to the company that made the Linotype machine. They did also make a small line of adjustable reamers and taps that had been developed in the course of developing the Linotype machine and working out its manufacturing process. |
