2 Claims.

This invention relates to paper carriages for accounting machines, and is illustrated in connection with the type of carriage to be used on the machine disclosed in the application of Oscar J. Sundstrand, Serial No. 581,800, filed December 18, 1931. It is adapted to be used in association with the improvement disclosed vin the application of Walter A. Anderson, Serial No. 150,367,

filed June 25, 1937, and is an improvement over the mechanism disclosed in United States Patent No.. 2,060,954, issued to,0scar J. Sundstrand on November 1'7, 1936.

The primary object of. the present invention is to provide a mechanism that will facilitate the insertion and feeding of both front fed and rear fed paper.

-Wi th this and incidental objects in view, th

invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims,- and a preferred embodiment of which is hereinafter described with reference to,

the drawings which accompany and form part of the specification.

- Figure '12 is a perspective view showing the auxiliary paper chute in position on the carriage Carmen m Gasman.

Referring to Figure 1, the carriage is mounted for movement along a track I. The track is provided with grooves 2 (Figure 2) to receive rolls 3, received also by oppositely disposed grooves in carriage frame I. As the carriage moves from right to left, it is stopped in various columnar positions so that type bars 5 on the accounting machine may print against platen 6 (Figure 1). The mechanism for tabulating the carriage from column to column and for returning it to its initial position is disclosed in application Serial No. 581,800.

The carriage is adapted to accommodate rear fed paper such as the continuous journal sheet -".'I and a tally roll 8, as well as front fed paper such as a ledger sheet H.

Mechanism for rotating the platen Referring to Figures 1 and 11, the platen 6 may be rotated manually by knobs I2 secured to each end of the platen shaft l3, and may be rotated automatically during operations of the 30 machine by a feed pawl ll (Figure 11) The feed pawl is pivoted at i 5 to a lever,,l6' pivoted on the carriage frame at l'l. Asprlng I8 is secured to feed pawl l4 and tends to rotate the feed pawl clockwise aboutits pivot IS. A feed adjusting bracket II is pivoted on the carriage at 22 and has an arm Mi connected to the main body portion of the bracket by a yoke 24. Arm 23 carries a stud 25 lying between the arm and the main portion of the bracket. This stud acts as a stop jig-limit the clockwise movement of feed pawl H about its pivot. A detent 26 is pivoted on the carriage at 21 and has notches -28 in its right hand edge cooperating with a stud 3| on bracket 2| to hold the bracket in any adjusted podtiona 45 A wing 32 connected to deteht 26 holds notches 28 in engagement with stud 3 I.

/-AS explained in Patent No. 2,060,954, the platen rotated during certain operations of the mahine' by lever It being rotated counter-clockwise about its pivot l1. This moves lever, II to the left, its upper edge remaining in contact with stud 25 through the tension of spring It. When bracket II is in the position shown in Figure 11, and feed pawl 14 is movedto the left during an operation of the machine, the left end of the feed pawl passes under tooth 33 on ratchet wheel 34 secured to platen shaft l3, but contacts tooth 35 so that further movement of the feed pawl to its dotted line position shown in Figure 11 rotates the platen one line space. A spring pressed detent, including two similar levers 36, is pivoted at 31, and carries a roller 38 situated between the two levers at their left ends (see also Figure 1). A spring 4| holds roller 38 in engagement with the teeth on ratchet wheel 34 to hold the platen in advanced position.

If the operator desires to have the platen advance two line spaces during one operation, or, on the other hand, not advance at all, it is only necessary .for him to grasp the left end 42 of bracket 2| and move it up or down. A suitable index reading 0 1 2 is provided on the carriage side plate 43 to indicate the position of bracket 2|. When the bracket is in its upper position, the left end of feed pawl I4 is elevated sufficiently to engage tooth 33 instead of tooth 35 and thereby rotate the platen two line spaces instead of one in its movement to the left.

When bracket 2| is in its lower position, the

left end of feed pawl i4 is lowered to such an extent that it will engage neither of the teeth 33, 35 when it is moved to the left, thereby failing to advance the platen.

Mechanism for guiding and feeding rear fed pap Referring to Figures 1 and 2, the rear fed paper is shown in the form of a continuous journal sheet 1 and a talley roll 8. The journal sheet I is supported on a spindle 44 rotatably mounted between side plates 45 and 46, in turn supported on a square rod 41 held securely between the carriage side plates by two screws, one of which .is shown at 48 (Figure l). The plates are supported at their left ends by a rod 49 secured in the carriage side plates by two screws, one of which is shown at 50 (Figure 1). Plates 45 and 45 each have secured thereto a sleeve 58a (Figure 14) carrying a bracket 5| into which is threaded a set screw 52. By this means, plates 45 and 46 may be moved along rod 41 to the required position and secured in place by tightening set screw 52. Each of the plates 45 and 46 carries an arm 53 having a portion 54 bent at a right angle and pivoted on short rods 55 (one being shown in Figure 14) secured in the side plates. A spring 56 is secured to each arm' 53 and to the corresponding plate to hold'the arm against the journal sheet I. These arms 53 serve to keep the journal sheet taut.

As the journal slreet passes from the roll it first passes over a paper table 51 extend ng across the entire width of the carriage and having at its opposite ends flanges 58. The flanges are apertured to receive the opposite ends of a rod 6| secured to the side plates of the carriage by two screws. one of which is shown at 62 (Figure 1). The paper table 51 extends downwardly to a point quite close to the platen and is held at its lower end securely in the carriage frame by screws (not shown). A pair of paper guides 83 and 64 lie over paper table 51 and are curved at their upper ends, as shown in Figure 2. Brackets such as 65 are secured to guides 63 and 84 and are apertured to receive rod 6|. Brackets 65 grip rod 6| sufiiciently to retain the paper guides in any position to which they are adjusted.

After passing over the paper table 51 the journal sheet then passes between the platen and rear feed rolls 66 (see also Figure 5). Feed rolls 66 are each supported between flanges 61 of a plate 68. A pair of short arms II project upwardly from plate 58 and are bent slightly forwardly of the platen. A short flange 12 also extends upwardly from plate 58 and is bent forwardly at the.

plate (see also Figure 2). A pair of ears 13 extend upwardly from plate 68 and are apertured to receive a rod 14 secured in the side plates of the carriage. A U-shaped bracket 15 is apertured to receive rod 14 and is also apertured to receive a fiat sided shaft 16 journaled in the carriage side plates. A pair of springs 11 are secured to the bracket 15 and to flange 12 on plate 68 to tensionv plate 68 and roll 66 clockwise about rod 14. Manipulative levers 18 are secured to each end of shaft 16.

Referring to Figure 2, it will be noted that when the feed rolls 66 lie in their operative position against the platen, one of the longer fiat sides of shaft 15 lies against short arms 1|. When it is desired to move the feed rolls away from the platen, it is only necessary to rotate one of the levers 18 a slight extent. This causes one of .the edges of shaft 16 to move arms II to the left (Figure 2), and rotate the plate 68 and roll 66 counter-cfockwise about rod 14.

After passing between the platen and the feed rolls 68 the paper then continues around the platen and passes under a pressure finger 8|. This finger is secured to substantially the mid portion of a tear plate 82 (see also Figures 12 and 13) secured to a square rod 83 and having a serrated rear edge 84. Rod 83 is pivoted at its opposite ends in the carriage side plates 43. A

finger piece'85 (Figure 13) is provided on the left end of rod 83 and carries a stud 88 that bears against the upper edge of side plate 43 to limit the movement of the finger piece. A light spring 81 secured to the finger piece and to the carriage side plate tensions the finger piece and pressure .finger 8| clockwise about rod 83, as seen in Figure 13, to normally hold the pressure finger light- 1:; against the platen. When feeding the journal sheet aroundthe platen, the operator moves the finger piece 85 slightly counter-clockwise (Figure 13) to raise pressure finger 8| away from the platen. The paper is then inserted between the pressure finger and the platen, after which the finger piece 85 is released. Since the pressure of finger 8| on the paper is very light, it does not interfere with the feeding movement of the paper.

Further rotation of the platen moves the paper rearwardly under tear plate 82. Another plate 88 is suspended under tear p ate 82 and is supported by ears 9| and 92 apertured to receive rod 83. The ears fit loosely on rod 83 so that movement of rod 83 does not effect plate 88. Two similar ears 93, one of which is shown in Figure 12, project downwardly from the plate, their lower ends resting on the lower portion of paper table 51. By these ears 9|, 82 and 93, plate 88 is supported in the position shown in Figures 12 and 13 to direct the journal. sheet upwardly after it leaves the platen, thus preventing its contact too soon with the portion of the journal sheet that is moving downwardly toward the platen, and thereby preventing the leading edge from being again carried around the platen. After the journal sheet passes to the rear of tear plate 82.'it passes over the journal sheet roll and then rests on two guide arms 94, one situated at each side of the journal sheet. One of these arms is shown in Figures 1 and 2. Each arm 94 is provided with a U-shaped bracket 35 to hold the journal sheet against movement laterally of the carriage as the carriage tabulates from column to column. Arms 34 are attached to plates 45 and 46 by sleeves 50a (Figure 14) and rods 55.

A tally roll holder having side plates 96 connected by a rod 91 and a bracket 33 is supported on the carriage to the rear and at one side of the journal sheet 1, as shown in Figure 1. The tally roll holder is placed on the carriage by first being tween the two sleeves. A spring I01 urgessleeve I04 away from sleeve I02 so as to hold shoulders I03 'on sleeves I02, and I04 in engagement with recesses III (Figure '1) on side plates 96. When lowering the side plates over rod IOI it is only necessary for the operator to move sleeve I04 toward sleeve I02, then lower the side plates until rod I M is within recesses III, and then release sleeve I04 to the tension of spring I01. This latches the tally roll holder securely in place. An arm II2 (Figure 7) is pivoted in upstanding ears at the opposite ends of bracket 33 and is pulled toward the tally roll by a spring II3. This 'arm serves to keep the tally roll taut. A short flnger I I4 extends upwardly from bracket 33 to prevent excessive counter-clockwise movement of arm I I2 when the tally roll is removed from the holder. The tally roll is supported in the holder on a rod H5 having a knurled knob H6 at one end and a threaded portion at its other end received in an internally threaded stud I I1 secured to the right hand side plate 96 (Figure '1).

Mechanism for guiding and feeding front ,fed

i pe

For introducing front fed sheets, upper paper guides II3 (Figures 1 and 2) and lower paper guides I2I are provided. The left hand upper guide H3 is provided with an edge guide I22, and the right hand lower guide I2I is provided with an edge guide I23, the latter being flared outwardly to the right at its upper portion. Guides I I3 are supported on rods I24 that extend through lower guides I 2I and are secured to arms I25. Arms I25 are in turn secured by screws I26 and I21 (see also Figure 12) to arms I28 and -I3I pivoted on semi-cylindrical studs I32 and are he'd in engagement therewith by studs I34. The semicylindrical studs I32 are secured, to spacing plates I33. which in turn are secured to carriage side plates 43. The upper ends of guides H8 (Figures 1 and 2) are supported by a rod I35 secured to two arms I-36,-in turn supported by rods 49 and I31. Guides I I3. are connected to rod I 35' by brackets I33 slidably mounted on guides 3: This sliding movement is obtained, as shown in Figure 8, by having brackets I33 each slotted to receive-three bolts I4I secured in guide II3. A

spring I42 extending \fromthe bracket to the upper bolt I4I tensions, the bracket upwardly. A sleeve I43 for each bracket is-secured on rod I35 by a set screw I44, between the two side flanges otthe brackets,-to prevent lateral movement of the latter.

Y "The lower paper. guides I have downwardly downwardly between the. platen and the type .theframe of the accounting machine.

bars (Figure 2). Paper guides I2I are supported on a rod I41 secured to arms I23 and Ill by screws I26. A key'pin I43 (Figure 10) is inserted in the vsemi-circulargrooves provided in rod I41 and in the downwardly extending flanges I6I (Figures 1 and 10) of guide I2I. Key pin I43 prevents guide I2I from rotating on rod. I41, but allows it to be adjusted. axially of the rod to accommodate journal sheets of different widths. The key pin may be secured in guide I2I by any suitable means.

After the paper passes downwardly through the chute, it is directed under the platen first by the upper portion of a: plate I52 secured to One or more deflectors I53 are provided adjacent type bars 5 and have surfaces I54 to prevent the paper from catching on the rear ends of the type if the papershould have a tendency to curl in this direction. Plate I52 deflects the paper toward a front feed lip I55 (Figures 2 and 5) secured on a square rod I56 pivoted in the carriage side plates 43. p

Further insertion of the paper brings it between edge guides I51 (Figure 6), adjustably mounted'on rods I53 secured in the carriage side plates 43. Thumb screws I6I (Figures 2 and 6) retain the guides I51 in any adjusted position.

The paper is then deflected upwardly between the rear feed-rolls 66 and guide plate I62 suitably secured between the carriage sideplates. Further movement brings the paper into contact with the lower edges of deflectors I63 supported on rods 14 and I31. The paper then continues rearwardly between deflectors I63 and plate I62 until it strikes adjustable paper stops 164, one of which is shown in Figure 2. Stops I64 may be adjusted along plate I62 by turningthe adjustable stop mechanism are disclosed in application Serial No. 92,164.

After the paper is fully inserted, it is necessary to bring it in contact with the platen at the printing point, and also to hold it firmly against the platen at some point for the purpose of line spacing. It is-also necessary to move the paper guides I2I and theadjacent structure to the rear to allow type bars 5 to rise the necessary extents during the machine operations in the several columnar positions.

To bring the paper against the platen at the printing point, front feed lip I55 (Figure 2) is mounted for pivotal movement whereby it can be moved to a position quite close to the platen, as shown in Figure 3. This serves to bend the paper around the platen from a position below the printing point. Pressure rolls I66 (Figures 1, 2 and 3) are provided to bend the paper around the platen from a position above the printing point, and also to hold the paper firmly against the platen for line spacing. The operative position 'of these rolls is shownin Figure 3. Rolls I36 are pivotally mounted in'supportingbrackets I61 supported ona square rod I63 secured to arms I23 and I3I by screws I21 (Figures 1 and 12). The pressure rolls and their supportingv brack'ets may be adjusted along rod I63. and are held in any adjusted position by thumb screws I 1|. g

d The movement necessary to bring rolls I66 into efiective position is sufficient to move guides I2I and their adjacent mechanism to the rear a suillcient distance to beout oi the path of type bars 5. The rearward movement of these parts is also used to pivot front feed lip I55. In moving the parts from the position shown in Figure 2, which may be called the open position of the ront feed mechanism, to the position shown in Figure 3, which may be called the closed position, rolls I66 and lower paper guides I2I move to the rear, along with arms I28 and I3I and rods I24, I41 and I68, the entire'assembly pivoting about studs I32. As rods I24 (Figures 2 and 3) move rearwardly about studs I32 as a pivot, upper paper guides II8 must move relatively to brackets I38 a slight extent. The slidable connection shown in Figure 8 between these parts accommodates this relative movement. The closing movement of the above parts moves the front feed lip from its open position shown in Figure 2 to its closed position shown in Figure 3 by the following parts.

A pair of arms I12 (Figures 1, 2, 3 and 5) are secured at the opposite ends of a plate I13 pivoted at I14 in the carriage side plates. A spring I15 (Figures 2 and 3) tensions arms I12 and plate I13 clockwise about their pivot I14, the clockwise movement being limited by studs I16 (Figures 1 and 12) in arms I28 and I3I. The front feed lip I55 is provided with earsITI at its op-- posite ends, the ears lying directly behind arms I12. When the front feed mechanism is open, arms I12 and front feed lip I55 lie in the posi tion shown in Figure 2. When the mechanism is closed, spring I15 draws arms I12 to the rear, and through contact with ears I11, rocks the front feed lip upwardly to the position shown in Figure 3, square rod I56 pivoting to accommodate this movement. When the front feed mechanism is again opened, studs I16 move arms I12 forward, allowing a spring I18 (Figures 2 and 5), secured to a downwardly extendingarm I8I of front feed lip I55, to move the front feed lip to its open position shown in Fi u e/. 1. e The front feed mechanism is held in either its open or closed position by a detent I82 (Figures 2 and 12) pivoted on arm I28 at I83. Detent I82 is provided with a spring I84 to hold either of two notches in the detent in engagement with a stud I85 secured in the left hand carriage side plate 43.

Auxiliary paper chute for front fed paper At times it is necessary to insert front fed sheets in the machine and have what is known as headings" printed on them. A heading is merely a number that represents a. balance brought forward from a previous sheet. The headings are ordinarily printed at the top of the new sheets and are all printed in the same location on the sheets. Sinceg'during the printing of these headings, it is not necessary to tabulate the carriage from one column to another, nor to line space the paper, it is not necessary that pressure rolls I66 be used to hold the paper against movement in the platen or to assist in feeding the paper. It would, therefore, be desirable to operate the machine to print these headings without the operator having to open and close the front feed mechanism between each operation.. However, as mentioned before, it cannot be operated while the front feed mechanism is openbecause these parts would interfere with the necessary upward movement of type bars 5. The following parts have,

- therefore, been provided for directing front fed paper into the machine with the upper parts of the front feed mechanism closed.

Referring to Figures 4 and 12, an auxiliary paper chute I86 is provided with side walls I81 secured at the opposite ends of front and back plates I88 and I9I. Plates I88 and I9I are flared at their upper portions, as shown in Figure 4, to facilitate insertion of sheets. The mid portions of plates I88 and I9I are indented at I92 and I93 to provide ample space for the hand of the operator. The auxiliary chuteI86 is supported on the front feed mechanism by itsside walls I81 being hooked over rod I41 and resting against rod I68. A latch I94 is pivoted to the right and side wall I81 at I95 and has a hook I96 held in contact with rod I68-by a spring I91.

When auxiliary chute I86 is used for inserting front fed sheets, it is necessary to open front feed lip I55 in some manner other than by the customary opening of the front feed mechanism as described above. .For this purpose a lever I98 (Figures 4 and 12) is provided. This lever is situated outside the left hand carriage side plate 43 so that it can be manipulated by the operator. A cam 28I is connected to lever I98 by a short shaft 202 (Figure 4). Movement of lever I98 from the position shown in Figure 3 to that shown in Figure 4 moves front feed lip I55 from the position shown in Figure 3 to that shown in Figure 4 through the contact of cam 28I with a short flange 283 (Figures 3, 4 and 12) secured to rod I56 at its left end. A detent 284 is pivoted on the carriage side plate at 285 and is held in contact with a stud 286 on cam 28I by a spring 281. Detent 284 is provided with two notches to retain lever I98 in either of its two positions.

The sheets on which the headings are to be printed may now be inserted downwardly between plates I88 and I9I. They are deflected rearwardly by plate I52 and pass between front feed lip I55 and the platen, the front feed lip having been opened by lever I98 prior to the insertion of the sheet. Further insertion of the sheet causes it to move rearwardly, in the same manner as described above for other front fed paper, until it is stopped by paper stops I64.

A finger 288 (Figure 12) is secured to the auxiliary chute and extends downwardly to -a position quite close to the platen. This finger 288 holds thev paper sufficiently close to the platen at the printing point to make it unnecessary to close front feed lip I55 after each sheet is inserted.

By the provision of the above parts, the operator may print headings on a number of sheets without having to manipulate the carriage in any manner between the successive printing operations.

OPERATION In using the present construction, the operator first opens the front feed mechanism to the position shown in Figure 2 and inserts the front fed sheet. He then passes the journal sheet 1, together with the necessary carbon paper, over paper table 51 and inserts it downwardly until it stops where the rear feed rolls contact the platen. The platen is then rotated to bring the journal sheet 1 around the platen, the front fed paper serving as a guide for the leading edge of the journal sheet. The operator then moves brackets I38 downwardly on paper guides II8 to disconnectthem from rod I35, and pivots guides I I8 forwardly to the dot and dash position shown in Figure 2. This permits'free access to complete insertion of the journal sheet. He then presses finger piece 85 and rotates the platen until the journal sheet is between pressure finger 8| and the platen. He then continues rotatin the platen, at the same time directing the paper, with his other hand, under tear plate 82. From this point the journal sheet will feed automatically., The tally roll 8 is then fed around the platen in a similar manner except that there is no pressure finger 8| cooperating with the tally roll. Paper guides II8 are then moved to their full line position shown in Figure 2. The front fed paper may then be adjusted to its proper V location for printing and the front feed mechanism closed by the operator pressing rearwardly on rod I41 or the associated parts. 4

At a predetermined time the front feed mechanism is automatically opened, in the manner described in application Serial No. 150,367. The front fed sheet may then be removed and another inserted. At predetermined intervals the platen is automatically advanced to line space the paper. When it becomes desirable to adjust the alignment of the journal sheet or .tally roll, one of the levers, I8 may be operated to move pressure roll 66- away' from the platen. After the paper is adjusted the lever is returned to its original position.

When it is desired to print headings in the same location on a number of front fed sheets, the auxiliary chute I86- is placed in position on the front feed mechanism and lever I98 is op- 'erated to open front feed lip I55. The paper stops I64 are then adjusted in the manner disclosed in application Serial No. 92,l64, so that removed without further manipulation of the carriage.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the oneform of embodiment herein disclosed. for it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.
