Line 61: Funded largely by the [[Knight Ridder\|Ridder]] newspaper interests, the [[Intertype Corporation]] developed ([[circa\|c.]] 1914) a compatible version of the Linotype machine when the patents ran out and it became quite popular as well. This led to a long-lasting legal fight by the Mergenthaler Linotype Company (who eventually lost). Various methods were used to power the Linotype / Intertype machines, the most common being a fractional horsepower motor, one wired for single-phase 60 Hz alternating current eventually becoming the default offering. To accommodate the customers' requirements, motors were also built to be powered from direct current, 25 Hz AC, or 50 Hz AC circuits. Also, motors wound for various polyphase circuits (two-phase, 3-phase, wye, delta, etc.) were made available for the customers as well. In a few cases, where electricity was not available, it was possible to drive the machine by a belt connected to a [[line shaft]]. A common {{frac\|1\|2}} HP single- or three-phase electric motor is sufficient to operate a Linotype or Intertype, although very early machines may have been operated from a [[line shaft]] system. Late machines were either 60 Hz or 50 Hz alternating current, although early machines were made with direct current or 25 Hz or other alternating current motors, including two-phase motors. Initially, the metal pot was heated by gas (whether natural or '[[Coal_gas\|manufactured]]'), but an electric pot was later developed and which became a standard option. As with the motors, the control machinery for the metal pot heaters was produced in a variety of voltages and in direct or alternating current versions. For locations with access to neither gas or electricity, the gas-fired pot could be fitted with a burner kit to allow the use of kerosene or other '[[white gas]]' fuels. The metal pot could be either electric- or gas-heated, at the customer's option, for late machines. For early machines, kerosene and [[white gas]]oline were also options. It was thereby possible to install a Linotype machine in a premises which was without access to public utilities. Thus, regardless of the power sources available (within reason), it was possible to install a Linotype (or Intertype) machine in almost any newspaper office, whether in a remote mountain community or a downtown office in an urban metropolis. === Typograph and Monoline ===
