PAPER CARRIAGE FOR ACCOUNTING MACHINES Filed June 29, 1938 I s Sheets-Sheet 3 INVENTORY WALTER A. ANDERSON yflg ATTORNEY Patented nee. 24,- 1940 UNITED STATES PAPER CARRIAGE FOR ACCOUNTING MACHINES Walter A, Anderson, Bridgeport,-Conn., assignor to Underwood Elliott Fisher Company, New

, York, N. Y., a corporation of Delaware Application June 29, 1938, Serial No. 216,460 a 1 Claims. (01. 197-128) This invention relates to paper carriages for accounting machines, and more particularly to paper holding apparatus therefor;

In modern accounting practice it is' frequently necessary to enter only a single line of posting on each form, making it desirable to remove and insert the forms in rapid succession; Also, it is frequently necessary to print upon bank checks or short memorandum slips thatido not have suflicient length to be held in printing position by the usual paper holding devices.

An object of the present invention, therefore, is to provide a paper holdingmechanismfor long work forms, having means for properly holding such forms in printing position and being operable either'manua'lly or automatically to an open or closed'position, whereby to facilitate the in sertion and removal of the forms during successive one-line printing operations. 20 Another object of the invention is to provide an adjustable means for supporting and holding relatively short length forms, such as checksand the like, in printing position on the carriage platen. I T 25 Withthese and incidental objects in'view, the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in'appendingclaims, and a preferred embodiment of so which is hereinafter described with reference to the drawings which accompany and form part of this specification.

I v a a The invention is illustrated in connection with so thetypeof carriage used on the machine disclosed inthe applicationof Oscar J. Sundstrand, Serial No. 581,800, filed December 18, 1931 which matured as Patent'No. 2,194,270, March 19, 1940. It is adapted to be used on the type of carriage l5 disclosed in United States Patent No 2,060,954,

issued to Oscar J.'Sundstrand, on November 17, 1936, or on that'disclosed inthe United States applications of Walter A. Anderson, Serial No. 92,164, filed July 23, 1936 and Serial No. 192,675, filed February 26, 1938 which matured as Patent '6 No. 2,185,424,.January 2, 1940. I

Carriage in general 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. 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 printon work forms fed around the platen 5; The mechanism for tabulating the carriagefrom column to column and for returning it to its initial position is disclosed in Patent No. 2,194,270. The carriage is adapted to accommodate rear fed paper such as ajournal sheet 1 and front fed paper such as a ledger sheet 8 (Figure 2), as well as small forms suchgas a check 9 (Figure' 1 "Theplaten may'be' rotated manually by knobs l2 secured't'o each-end of the platen shaft' l2, and may be rotated automatically during operations of the machineby a'feed pawl It co-' operating with teeth 0"a ratchet wheel l5 se-- cured to shaft IS. The mechanism for operating pawl ll, together with the adjustable mechanism therefor, isfully disclosed in Patent No. 2,060,954. I

' Mechanism for guiding and feeding rear fed I w forms Referring to Figures 1 and 2, the. rear fed form 1 passes downwardly'between guides l8 and, I1, and over apapertable ll extending across the entire widthjof the carriage andjha'ving at'its opposite'ends ears l9. The ears areapertured to receivethe'opposite ends of a rod 20 secured 40 to side plates 2| and 22 of the carriage by two screws,- one of which is shown at "(Figure 1). The paper table e iids downwardly to a point pquite close to" platen 6, and is held at its lower end by. screws (not shown).' The guides l6 and 11 are arranged to lie over table I8 and are curved on their upper ends, as shown in Figure 2. Finger pieces such as 24 are secured to guides l6 and I1 andi'are apertured to receive rod 20. The finger pieces grip rod 20sufllciently to retain the guides.

,in any position to which they'are adjustedalong rod 20. I I

The journal sheet I then passes between platen 6 and rear feed rolls 25. Rolls 25 aresupported in trucks 2 Div.0ted at 21 on brackets "secured by screws (not shown) to table l3. Brackets 23 are apertured to receive a flat sided shaft 29 journaled in the side plates of the carriage. Springs 30 connected between an offset lug on tr .lCkS 26 5 and a formed lug on brackets 28 tension the trucks clockwise about pivots 21 to bring rolls 25 into frictional contact with the platen. Upstanding lugs 3i on trucks 25 lie adjacent one of the longer flat sides of shaft 29 when the rolls are in this position. Manipulative levers 32 (Figures 1 and 2) are secured to each end of shaft 29. When it is desired to move the feed rolls away from the platen, it is only necessary to rotate one of the levers 32 forwardly a slight extent. This causes an edge of shaft 29 to move lugs 31 toward the left and rotate trucks 26 counter-clockwise about pivots 21 thereby moving rolls 25 away from the platen.

From rolls 25, the paper continues around the platen and passes under auxiliary feed rolls 33, and then upwardly out of the carriage. In order to facilitate insertion of this form between feed rolls 33 and the platen, rolls 33 are mounted on the front feed paper structure which is arranged to be swung upwardly about shaft 33 as apivot, to remove the rolls from contact with the platen. This swinging structure is more fully described below.

Mechanism for guiding and holding front fed paper For introducing front fed sheets, right and left guide chutes 34 and 35, respectively, are provided. These chutes are formed with sides 33 which act as edge guides, and are secured on separate brackets 31 (Figure 3). Brackets 31 are apertured (Figure 5) to receive a square shaft 33 extending across the carriage and journaled in plates 39 (Figure 1) secured on the carriage side 4 walls and secured in position by screws such as 40. Forwardly extending arms 41 and 42 are mounted on shaft 33 adjacent plates 33 and are connected at their forward ends by a shaft 43. The lower ends of brackets 31 are recessed as at 45 44 (Figure to fit snugly in annular grooves provided in collars 45 slidably mounted on rod 43. Thumb screws 43 threaded in brackets 31 and bearing against shaft 33 maintain the brackets and chutes in their laterally adjusted position 50 along shafts 33 and 43.

The paper is passed downwardly through the chutes and is directed under the platen first by the upper portion of a plate 41 secured to the frame of the accounting machine.

55 deflectors 43 are provided adjacent type bars 5 and have surfaces 45 to prevent the paper from catching on the endsof the type if the paper should have a tendency to curl in that direction. Plate 41 deflects the paper toward a front feed 60 lip 50 secured between the carriage side plates 2! and 22. Further insertion of the paper causes it tobe deflected upwardly between the rear feed rolls 25 and a guide plate 5| secured between the carriage side plates. Further move- 65 ment brings the paper into contact with the lower edges of deflectors 52 supported on pivots 21 and a rod 53. The paper then continues rearwardly between deflectors 52 and plate 51 until it strikes adjustable paper stops 54, one of which is shown in Figure 2. Stops 54 may be adjusted along plate 5i by turning a knob 55. The details of this adjustable stop mechanism are disclosed in application Serial N0. 92,164.

After the paper is fully inserted, it is necessary thatlt be held firmly in position during the One or more.

printing operations. To accomplish this there are provided on each of the chutes 34 and 35 clamping members 53 pivoted on screws 51. A link 58 is pivotally connected to the upper end of each clamp 56, and, by pin and slot connection 62, is connected to upstanding arms 59 flxed on collars 45. Springs 60 (Figure 5) connected between studs 61 on the rear ends of links 53 and the pins ofthe pin and slot connection '32 normally tension clamps 55 counter-clockwise, as viewed in Figure 1, causing lips 53 formed on the lower ends of the clamps to yleldlngly press the paper against the rear walls of chutes 34 and 35 to hold it in position for printing.

The apertures of arms 58 are provided with keys lying in a key slot ID in shaft 43. This insures rotation of arms 59 with shaft 43, but permits them to be moved along the shaft. A lever '64 is secured to the left end of shaft 43 for rotating the shaft to release clamps 55 from contact with the front fed paper. An arcuate slot 65 (Figure 3) in lever 64 embraces an extended pin 66 in shaft 38 to limit the rotation of shaft 43. A spring 61, superior in strength to springs 35, is connected between pin 63 and a stud 33 secured in lever 64, whereby the lever and parts connected therewith are tensioned clockwise to their normal position, i. e., with clamps .53 in closed position, as shown in Figure 3. To release the clamps, it is merely necessary for the operator to press lever 64 rearwardly. This movement rotates shaft 43, taking up the lost motion in the pin and slot connection 62 and moving links 58 rearwardly to rock clamps 53 about screws 51 to their open position, as shown in Figure 2. A lever 69 (Figures 1 and 5) pivoted on a screw 13 secured in bracket 31 is arranged to latch the clamps in open position against the tension of spring 61. The lower end of this lever is formed with a hook 1|, which rests on top of pin 32 when clamp members 56 are in closed position, as shown in Figure 5. A spring 12 connected between this lever and a stud 13 on the side 33 of chute 34, tensions the lever counter-clockwise of screw 10 and holds the lower edge of hook 11 in contact with pin 52. Upon movement of lever 34 and link 58 toward the rear of the machine, lever 69 swings counter-clockwise and hook 11 engages pin 52 to latch clamps 53 in open position. The form 8 is then inserted and lever 33 pressed rearwardly to release shaft 43 for forward rotation under the tension of spring 31. During this movement, arms 59 take up part of the lost motion in pin and slot connections 32 and cause clamps 53 to press firmly against the paper under the tension of spring 30. After the printing operation has been completed, the form may be withdrawn without releasing clamps 53, the tension exerted upon the clamps by spring 33 being of an amount only sufllcient to firmly but yieldingly hold the paper.

Frequently it is desirable to have the clamps 53 open automatically as the carriage returns after a printing operation. To accomplish this, the following means are provided.

A depending lever 14 (Figure 1) secured on the right end of shaft 43 has a flange ll lying in the path of an arm 13. Am 13 is pivoted at its rear end on a stud 11 secured in a lever 13, and is guided by shaft 23 for forward and rearward movement, arm 13 resting on the shaft between lever 32 and the carriage sidewall. The lever 13 is pivoted on a screw stud 13 for oscillating movement, the screw passing through a slot 33 in the upper. end of the lever. The lower end of'lever 13 carries a roll 31 arranged to engage, during the return movement of the. carriage, a cam plate I! secured on. carriage bed-.1.

A guide bar Ill fixed to sidewall-II conilnesv lever ll .against lateral displacement.= A spring 03 :5 conneotedbetween stud l1 and a stud 1 Han bar I tensions-the, lever downwardly and :rear- 'wardly; On the; return stroke of the carriage, roll lt-engages cam 82 and swings lever 51'' forward, .thrusting arm 18 forward, and rocking lever" and shaft "to release clamps i8. Lever 09 then-latches clamps H in open position in the same manner as when lever 04 is operated to release the clamps. After roll, ll passes plate l2, spring 83 returns it to its rear position shown in Figure 1. Then during the working stroke of the carriage, roll Ii engages an inclined surface 84 of plate '2 and raises lever "against tension of spring 83, to allow it to pass over the plate. The automatic clamp release mechanism may be disabled, when desired, by'raising lever ll suiiiciently to place roll 8| above the horizontal plane of cam 02. A latch 05 is provided to hold lever 10 in this elevated position. The latch is pivoted on stud 'II and is swung forwardly into engagement with stud" to hold lever 18 in elevated position. This mechanism is fully disclosed in theSundstrand Patent No. 2,060,954.

Mechanism for supporting checks or other like forms Referring now to Figures 1 and 2, plates 08 are provided with flanges 81 having elongated slots ll through which pass screws ll secured in sides 38 of chutes I4 and ll,whereby the plates 08 may be vertically adjusted thereon. Each of these plates carryflat spring clips 90, the lower ends of which pass between stationary pins 9| fixed on plates I. Pins ll provide a stop for position. An auxiliary bracket 02 may be provided on rods 38 and 43 to accommodate the checks in an offset relation to the ledger sheets, if desired. This bracket is similarly provided with a vertically adiustablepplate ll carrying a spring clip SI and pins I.

When it is desired to print a single line on each succession as the printing operationsare completed.

To facilitate the insertion of rear fed forms, the front feed structure above described is arranged to be swung upwardly and forwardly from the position shown in Figure 3 to the position shown in Figure 4. To do this, the operator merely grasps the shaft 41 and pulls upwardly, brackets 31 and the other parts swinging about shaft 30 as an axis. Arm 2 (Figure 4) hasa rearward extension 93 arranged to abut a stud this movement of the front feed structure.

A' depending arm I! pivoted on a stud N on arm 42 is provided with a notch 01 and a cam face 9| on its forward edge. A spring ll connected between the lower end of arm" and the the upper edge of checks or short forms and assist in locating these forms in correct printing The operator.

94 secured on the inner side of plate ll to limit carriage.v frame tensions the arm forwardly against an inwardly projecting stud I secured 'on' the carriage sidewall 22. When-the front ',feed structure is in closed position, as shownin Figure 3, cam face SI bears against-stud I00 and 5 junder'tension of spring '89 maintains the structure-firmly. in this posltion. 'When' the structure. is raised to 'the'positionj shown in Figure 4, notch 9'!v engages stud 100 and maintains the structure in raised position'to permiteasy'access 10 to the platen while introducing rear fed'forms. Feed rolls'33 (Figure 3) are mounted in trucks IM, pivoted at I02 in brackets 31. Springs Ill connected between extensions I04 of the trucks and studs I05 secured in brackets TI tension rolls 83 clockwise about pivots I02. By these parts, when the structure is closed rolls 33 yieldingly contact platen 8 and assist in feeding the rear fed paper.

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 one form of embodiment herein disclosed, for it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.
