New York, N. Y., a corporation of Delaware Application November 25,1933, Serial No. 699,647 11 Claims. (01. 197-127) The present invention relates in general-1 to bookkeeping machines in which the paper is fed; from in front, and down past theplaten, and; 17, 1936, though it will be understood that it may front readily ‘feed bemeans.‘ adapted to other machines more particularly to front feed means which; are swung from a paper-holding position against. the platen, to a paper~releasing position away from keeping machine is diagrammatically indicatedv 5, the platen. , In the paper-releasing position it sometimes happens that the front feed means tends to inter ,fere with the printing operation as a consequence Referring to the drawing, a Sundstrand book: in dot and dash lines in Fig. 1, and includes av frame I, a laterally movable. paper carriage 2,, a‘. platen 3, rotatable in the carriage, and a group» 01’. type bars 4. , As shown in Fig. 3, a lever 5, pivotally mounted of which, were the printing means to be operated. ‘ at 5a (Fig. 1) on the carriage 2 is adapted‘v to damage would possibly result. It is accordingly swing in a counter-clockwise: direction under; the usual to. provide a motor bar lock, or other dis abling means, to prevent a printing operation when the front feed means is in this paper releasing position. There are some bookkeeping operations how ever, in which it is desirable to retain one of a plurality of work pieces in the .machine for a second, and sometimes subsequent operations, as for example, a tally roll; the front feed means being moved to paper-releasing position at the conclusion of each working excursion of the paper carriage to permit removal of the re mainder of the work pieces. . in?uence of a spring 6 connected to the lever‘ at ‘I. A flanged rail 8, is rigidly connected; to the lever 5, at 9, by means of upturned end lugs I0 15 formed integrally with. the rail. The rail 8 has a ?ange II arranged to co-act with a lug I2 pro jecting upwardly from a lever I3. The lever I3 is pivoted at It onthe frame I, and pivotally con nected at I5 to the rear end of a motor lock lever IS. The front end of the motor lock lever has a pin and slot connection at IT with a rigid part of 0 the frame I and terminates in a forwardly ex tending nose II. A spring I9 connected to the motor lock lever It at ill-tends to slide the nose It is therefore an object of my invention to provide means to automatically unlock the motor bar as an incident to movement of the carriage I8 forwardly to underlie a lug 2I of a lock plate 25 22'. The lock plate, 22 is slidably secured to a motor bar 25 by pin and slot arrangement 23, 24. to position to print upon the retained work piece after the motor bar has been locked by move ment of the front feed means to position to per mit removal of the remainder of the work pieces. Another object is to provide means for defeat ing the motor bar disabling function of thefront feed means in positions of the carriage corre sponding with the printing position of the re of the motor bar, is effective to establish an elec tric circuit to a driving motor, (not shown) but it will be apparent that the movement of the motor bar 25 to make such circuit is not possible while the nose II of the motor lock lever I5 is under the The lock plate 22, when lowered by depression lug 2| of the lock plate 22. 0 - The front feed means is adapted to control the tained work piece. , tendency of spring It to block motor bar 25. Other objects and advantages will become ap The front feed means includes, in this instance, a parent from the following detailed description,‘ frame comprising a pair of side arms 28 mounted taken in connection with the accompanying for pivotal movement on the carriage about an drawing, in which; Figure 1 is a fragmentary side view of a ma chine embodying a preferred form of the inven tion; Figure 2 is a fragmentary plan view with cer tain parts indicated in dot and dash lines; axis defined by a cross rod 3|. Displacement of ‘ the side arms from the pivotal axis is normally prevented by pins 32, fixed to the carriage in position to act against the lower rear edge of the arms to hold the latter in bearing engagement with the cross rod II. The free ends of side arms 28 are rigidly connected for unitary movement Figure 3 is a fragmentary perspective view of certain parts shown in Figs. 1 and 2. Some of , by means including tie rods 29 and 30. these parts are broken away to shorten the views. Work pieces may be inserted in the carriage The preferred form of my invention is em 'from the front of the machine, or from the left, bodied in a Sundstrand machine of the general as viewed in Fig. 1, by rocking the side arms in type disclosed in Patent No. 1,198,487, issued Sep a counter-clockwise direction to the paper-receiv tember .19, 1916, and more particularly like that ing position, as shown in the same view. There- ' of my application Serial No. 610,043, ?ied May 9, 1932, which issued as Patent No. 2,060,954, Nov. after the side arms and their common bail are moved in a clockwise direction into position in 55 2 2,091,839 which they cooperate to hold the work pieces in printing position. Movement of the front feed means to printing position functions'to move the locking nose rear 5 wardly out of motor bar blocking position. As shown in Figs. 1, 2 and 3, the right hand side arm 28 is provided with an arcuately shaped member intended for a single cross-tabulation are in serted at the right hand section of the platen opposite the paper supporting rods 29 and 30. The work piece which is utilized in two or more ‘ successive cross-tabulations is positioned on- the platen opposite the part 36. At the conclusion of an advancing movement of the carriage the 33, the remote end of which carries a laterally ex front feed frame is rocked forwardly to paper tending pin 34 arranged to contact the upwardly ‘ releasing position whereupon the work pieces on 10 turned end 35 of the lever 5, and thus rock the the right side of the platen may be withdrawn .10 latter in a clockwise direction against the action while the carriage is returning to its ?rst colum of spring 6.
