automatically justify the same to the proper measugement, cast metal slug 1 therefrom with the type characters in re- | lief, properly distribute the types back 1 into their respective receptacles and lay
 the metal slug down before the operator | for his inspection, and to do this and | continue to do 1t, at a speed equal to the | attained and maintained swiftness of | four of the fastest hand composition rec | ords combined, establishes its qualities and fixes them beyond dispute.
 The keyboard mechalisn Is so con- structed that 1t can be operated at a rat 3 of speed equal to 10000 ems of composed
 matter per hour. (An em is the square of the hody of type, used as a unit by which to measure the amount of printed matter on page. For instance, there ara 26 ems to the line in this size type and 10.140 ems in 39O lines.)
 A machine set up ready for work oc- eupies a spaceAof about fouF feet square. and IS run by a friction belt. About one- third horsepower IS required to run the machine. A gas jet burning under the metal pot keeps the casting metal al- ways in a molten condition. An inclined stationary magazine contains channels in which the matrices are stored, each letter in its appropriate channel. These ma trices tend to slide downward out of the magazine by reason of gravity. but are held in check by escapements, one at the mouth of each channel From the es- opponents rods are extended downward to series of finger keys. there being a special key for each letter. punctuation
 point. etc.
 Each time a key is pressed 1t releases
 an eccentric-lever which. coming in con- tact with a moving rubber roller. lifts | to tha cha AaI
 exponent and permits a single matgix,
 bearing the character. to fall out of the
 mouth of the magazine and downward | through interpediate channels to an in-
 clined travelling belt, by which the ma
 trices are carried downward. one after
 another, and delivered into slotted as-
 seInbling block, which corresponds to the l printers composing stick and therein l they are set up, or composed side by side.. 1 in a line, or row, each right side up, with | the proper face to the front. A stationary box contains a number of spaces and a
 delivery device is connected with a finger
 bar by which the spaces are discharged and permitted to fall into the line at
 their proper places. N
 Thus it is that by manipulating thej
 keys the required matrices and spaces are delivered. one after another. and assem- bled in a line until the assembling block
 contains all the characters necessary to
 complete one line of print. But how is it wedged ight or "spaced out" as the
 printers would say? This Is done by one of the most ingenious devices of all.
 The spaces used are long wedges, with the thick end do va. They are, in fact double wedges a wedge being fastened
 to the thin end so that the two slide
 ca siiy together. If 1t were not for this I dOfIbIa Wadpp device ba pressed up between the matrices would force them wider apart at the bottom than at the top. By means of the double wedge they are separated equally at both ends. After these spaces have dropped into the line at the propar
 places, they are forced upward until the line is spaced out to it's full length.
 Next comes the casting process. A lever is depressed and the portion of the machine which casts the line and also that which carries the matri.es after usn up to the distributing bar-whieh has not had action before-is started. The com posed line of matrices is grasped by two fingers and carried to an elevator which conveys and presents the entire row of characters in the mattix line directly op- posite the face of the mold. so that when the mold is filled with metal to produce line of type, the metal flows into the matrices and produces their respective type characters in relief on the edge of the casting.
 Behind the mold wheel there is arrang- cd a pot in which type metal is main- tained in molten condition by a flame from a gas burner beneath. The pot has a delivery mouth, or channel. adapted to fit against and close up the rear face of the mold After the line of matrices is locked against the face of the mold. pump forces the metal out and 1t solidiaes
