  • matrices for each character each having a fixed thickness but not necessarily all of the same thickness.
  • justifying matrices expansionpansible space bands which are adjusted before casting between certain ranges of thickness.
  • the perforating operator at the transmitting station must accordingly be apprised of the length of the line remaining as each matrix is operated. This is accomplished by a counting device.
  • the counting device here described indicates to .the transmitting operator the totalized thicknessof the matrices in a line during the process of composition and it separately indicates the number and the minimum, maximum and variable thickness of the justifying matrices. It performs also a function of subtraction by which the totalized thickness of the fixed matrices and the minimum thickness of the justifying matrices are subtracted jointly from a predetermined length of the line and the net results is shown upon a scale, and by which also, at the same time the totalized thickness of the fixed matrices and the maximum thickness of the justifying matrices (expanded space bands) are subtracted jointly from a predetermined length of line; and
  • depression of a key closes a contact to operate a perforating magnet and also operates mechanically a counter. ;In such a device it is necessary to so adjust the mechanism that its two devices operate simultaneously, but this is not commercially practicable, so that under many conditions the mechanism will count but not perforate, or perforate but not count, depending largely upon the touch of the operator.
  • a clutch is released and as the clutch rotates, both perforating and counting operations must takeplace.
  • the device is so arranged that a single depression of a key can cause only one perforating and .countingoperation.
  • the durationof the energization of the perforatin magnet is uniform, regardless of the fingering of the keys. Chattering of the contact, a common fault when the contact is closed directly by the keys, is also prevented.
  • the counting mechanism must count not only the number of matrices but also must operate variably in accordance with the particular matrices oper- .10 ated. Furthermore a character in the upper case may be of different thickness than a character in the lower case, which must also be taken into account.
  • An object of the present invention is to provide means for remotely controlling a composing machine.
  • a further object is to provide means for integrating or totalizing the width of characters and justifying members.
  • Another object is to provide means whereby the amount counted for a particular key will be different for the upper and lower case positions of the key.
  • A' further object of the invention is to provide a chart comprising a plurality of scales, each scale being for a different number of justifying elements, and a shutter to cover portions of the scale representing matter already com-. posed.
  • a still further object of the invention is provide means whereby depression of a keywill result in both a perforating and a counting operation.
  • Another object is to provide means whereby depression of the carriage return key will result in a complete return operation regardless of the fingering of the key.
  • Still a further object of the invention is to provide means whereby the counter mechanism operates invariably and only when the perforating mechanism operates.
