Definitions

  • This invention relates to improvements in front-feed paper carriage constructions for accounting and the like machines.
  • An object of the invention is to provide an improved construction of power operated frontfeed paper carriage.
  • a further object is to provide a paper carriage operable by power to adjust it from a normal working condition to an open-throat or frontfeed condition and to return it to its normal closed or Working condition and to provide means to prevent operation of the power means to return the carriage to normal condition when the carriage is not properly conditioned for such return.
  • a further object is to provide means to prevent an operation of the machine provided with such a carriage from being initiated while the carriage is being adjusted from its normal working condition to its open or front-feed condition.
  • a further object of the invention is to provide a carriage with a platen movable from a normal working or printing position to a retracted or open throat position and to provide means to decelerate and cushion the final portions of such movements of the platen.

  • the words clockwise and counterclockwise will be used to describe positions and motions of elements of the machine as seen by an observer in front of, at the right, or above the moving parts in the positions in which they are located in the machine.
  • the words right, rightward, left and leftward will be employed to describe positions and motions as seen by an observer in front of the machine.
  • the words above, up, upward, below, down, downward, front, forward, rear, rearward, and behind will be employed to describe positions and motions as they occurin the machine when it is in its normal upright position.
  • the machine is a key-set, electric motor-driven machine adapted for a great variety of accounting, bookkeeping and other work involving calculation. It has a traveling front-feed paper carriage into which record material and work papers may be inserted from the front. I Operation of the machine may be initiated manually by depression of various motor bars and live function control keys on the keyboard or automatically by automatic function control means operating in accordance with the columnar positioning of the paper carriage. Certain of the motor bars as well as the automatic function control means also control operations of the paper carriage and parts thereof.
  • the paper carriage supports a platen which is movable from its printing position to a retracted or front-feed position and V reversely. Elements cooperating with the platento form a front-feed paper throat are automatically adjusted to open-throat position when the platen is retracted from printing position and automatically restored to closed- 4 throat position as the platen is returned to printing position.
  • the opening and closing of the carriage that is, the movements or the platen from printing to retracted or front-feed position and reversely as well as the adjustment of the throat-forming elements to their open and closedthroat positions are efiected by power derived from the machine drive motor independently of the columnwise movement or non-movement of the paper carriage and transmitted through direct drive connections which are effective independently of the cycling of the machine.
  • control of the opening and closing of the carriage can be effected automatically during machine operation as well as manually through a key on the keyboard without cycling the machine. Initiation of machine cycling is prevented while .the carriage opening and closin key is depressed, while the carriage is opening, and While the carriage is not in proper condition for automatic closing. Depression of the carriage opening and closing key is prevented while the machine is cycling and while the carriage is open and not in proper condition for closing.
  • the front-feed construction of the carriage is of an improved form providing for very easy and rapid insertion, alignment and removal of record material and work sheets.
  • the paper guides are adapted to rapid and easy changeover to accommodate the changes in paper sizes which may be required when changing from any program of work to any other program of work to be performed on the machine.
  • PAPER CARRIAGE- C'arrz'age frame and mounting The carriage W56 is supported on a movable race member IE6! (Fig. 3) having front and rear rail members with V-erooves Hit?) and N63 and tied together in parallel spaced relation by laterally spaced connecting portions.
  • the race member use is supported for movement crosswise of the machine by two lines of bearing rollers 1658 received partly in the grooves liltifl and I053 and partly in facing V-grooves in race rails '43 and i i (Fig. 10) which are mounted on the machine frame as disclosed in the above-mentioned copending application with small rollerretaining plates Hill (Figsl and 2) secured on their ends.
  • Theright and left carriage frame end plates Hide and will respectively have the forward parts of their lower edge portions secured to the respective ends of the movable race member 1526i by headed screws passing through the plates I889 and will and threaded into the ends of the front and rear race rails of the member IBM.
  • the plates H159 and mm are also braced and tied together by a rear cross rod I812 (Figs. 2 and 3) having at each end a reduced portion (not shown) threaded into the inward end of a post I973, the outer end of which is secured to the respective side plate i969 or I Lila by means of a headed screw threaded into the post through the side plate.
  • a guide supporting member i51 (Figs. 2, 3, e and 10) against the ends of which the plates W59 and I075 are secured by pairs of headed screws passing through the respective plates and threadedinto the ends of the member mm.
  • a light covcrplate i375 extends across the lower portion of the front of the carriage and has, at its upper corners, ears secured, asby screws, to the side plates i869 and I010.
