Application November 10, 1945, Serial N0. .627,856

This invention relates to accounting machines, and particularly to machines adapted for use in banks, especially in the proof departments thereof, where the various items are listed and `distributed for a proof balance at the end of each yday.

'machines of the general type shown in the following United States Letters Patent Nos. 1,619,796; 1,747,397; and 1,761,542, issued March 1, 1927;

February .18, 1930; and June 3, 1930, respectively,

to Bernis M. Shipley; No. 2,175,236, issued October 10, 1939, to Maximilian M. Goldberg; No. 2,141,332, issued December 27, 1938, to Charles H. Arnold, No, 1,693,279, issued November'27, 1928, to Walter J. Kreider; and No. 2,305,000, issued December 15, 1942, to Mayo A. Goodbar; and reference may be had to said patents for a complete illustration and description of such general types of machines. A more specic type of machine in which the invention is embodied is shown in United States Letters Patent No. 2,361,662, issued October 31, 1944, to Pascal Spurlino and Konrad Rauch.

This latter Patent No. 2,361,662 showsa machine having seven individual audit, classication, or listing tapes or strips, each carried by a removable frame adapted to be slid into and'out of the machine and having an interlocking means associated with the machine releasing mechanism to prevent operation of the latter unless all seven of the tape carrying frames are latched in their proper positions in the machine.

In that machine, as each tape is printed upon and fed forwardly past the serrated tear-olf plate, the free end of the tape, guided by a curved guide, is automatically coiled up within the unit. This guide is secured to the cover of the unit,and, when the operator wishes to tear off the printed coil of the tape, the cover is lswung downwardly, it being hinged at the bottom, and the operator pulls the coiled end of the tape Vout of the space within the curved guide and then tears this coiled end oli of the tape by means of the tearor plate.

Sometimes, especially when a large number of items has been printed on the tape, the coil of tape is much larger than normal and consequently more diicult to remove from the cover and curved guideand the paperV is often" torn during such removal. f

8 Claims. (Cl. 271--2.1)

Such conditions are eliminated by the present invention, which has for one of its objects the provision of a combined slidable paper chute and cover whereby the free end of the tape isl guided in a comparatively large arc, terminating in a straight line beneath the carrying frame, which carrying frame, except for the hinged cover, is substantially like that shown in said United States Patent No. 2,361,662.

Another object is-.to provide a novel slidable paper chute and coverY for a tape feeding mechanism, the chute having means 'to prevent accidental removal of the same from the machine.

VAnother object is to provide -a removable tape carrying frame having a tape feeding means with a combined cover and paper chute to guide the free end of the printed tape down and beneath the carrying frame.

Another object is to provide a slidable combined cover and paper chute for a tape feeding means 'adapted to be slid forwardly to expose a portion of the tape to facilitate inspection of printed items thereon, and at the same time make it easy for the operator to tear off the tape when desirable.

With these and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims, and a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form a part of this specification.

General description This invention includes a novel combined cover and paper chute for each of a plurality of removable tape carrying frames, such as shown in the Spurlino and Rauch Patent No. 2,361,662, above mentioned, which cover and chute replaces the hinged cover in which the free end of the tape is coiled.

The present combined cover and strip chute is slidably mounted in a rear support guide and a front support guide and when in position engages locating flanges of a lip on the tape guide plate over which the free end of the tape passes after leaving the feed roll.

Means is provided on the combined cover and strip chute to prevent its accidental complete removal from the machine, such means comprising a stop member on the bottom of the cover chute, which contacts the rear side of the front support guide, thus limiting the forward sliding movement of the combined cover and strip chute.

These combined cover and paper chutes extend rearwardly to substantially the rear edge of the machine, and thus on long analysis runs the free ends of the tapes come out of the chutes at the back of the machine.

A protective shield encases all of the paper chutes to protect the operators knees and also to prevent the operator from accidentally pushing the chutes out of place.

A hole is provided in the shield beneath each chute so that the stop thereon may be flexed upwardly, by the operator, out of stopping position when it is desired to completely remove the cover and strip chute from the machine. When in normal position, each cover chute is latched by a spring retaining latch, and to remove or slide the cover and strip chute the operator merely pulls on the knob on the cover and the retaining latch is cammed out of retaining position. When the cover and strip chute is pushed back into its operative position, the spring retaining latch snaps back into its retaining position.

Detailed description Since the individual tape carrying frame and the combined cover and strip chute for each frame, and the tape feeding means are all alike, a description of one unit comprising said mechanism will suffice for all.

The tape carrying frame and tape feeding means will be but briefly described, since the feeding means and the frame, except the new combined cover and paper chute, are substantially the same as illustrated and described in the abovementioned Spurlino and Rauch Patent No. 2,361,362, which may be referred to for a complete illustration and description of the frame and tape feeding means.

The several tape carrying frames are supported on a base plate 2@ (Figs. l and 8) secured to the bottom of frames 2| (only one being shown), which frames 2| support the main printing mechanism of the type of machine shown in said Spurlino and Rauch patent just above mentioned. The base plate 2li has secured to the top thereof a U-shaped member or channel 22, having guide flanges 23 to cooperate with the tape carrying frame. There is one channel '22 for each tape carrying frame, and in this application three frames are shown. This number may vary according to the needs of the business for which the machine is made. E'ach frame has sides 24 and 25 tied together near their lower edges by tie rods 2 and 28 and a tie bar 29, and near their upper edges by tie rods 3B, 3|, 32, and 33. The rod 2l' and the bar 29 rest on the tops of the flanges 23, and studs 35, carried by the sides 24 and 25, ride beneath the anges 23. The sides 24 and 25 also have flanges 35 and 3?, respectively, which ride beneath the flanges 23. Therefore, the listing tape frame is kept from any lateral movement and also from any up-and-down movement, the flanges 36 and 31 preventing lateral movement and also preventing any movement of the frames too far in an upward direction.

Pivoted on a stud 39 on the side 25 (Fig. 10) is a spring-actuated latch 4|? adapted to latch over a tie bar 4| (Fig. l) when the frame is properly located in its operating position in the machine. This tie bar 4| connects the printer frames 2|, as shown in the above-mentioned Spurlino and Rauch patent, which also shows a latch identical with the latch 40.

To remove the listing tape frame from the machine, the operator merely depresses the forward end of the latch 4D to release it from the tie bar 4|, whereupon the entire frame may be withdrawn from the machine after the combined cover and paper chute has been rst removed.

A listing tape 44 is fed from a supply roll 45 (Figs. 1 and 9), which is supported on a trunnion 46, projecting from the stud 39, and a trunnion 41 carried by a spring arm 48 secured to the side 24. From the supply roll 45 the tape i4 is fed upwardly over a roller 50, which is supported by a guide plate 5| secured to the sides 24 and 25 of the tape frame. The tape 44 is then fed upwardly over a roller 52 on the stud 30 and rearwardly over 'a roller 53 on the stud 3|, thence around a roller 54 on the stud 32, and then forwardly between a. feed roller 55 and a tension roller 55.

The feed roller 55 is adapted to be rotated counter-clockwise by means to be hereinafter described, so as to feed the free end of the tape 44 downwardly between a tape guide plate 5'! and a tear-off strip 58, and into the mouth of a combined cover and tape chute 6U, to be later described.

Individual tape feeding mechanism As previously stated, the tape 44 is fed between the feed roll 55 and the tension roll 55 (Fig. 1). Connected by a hub 6| to the feed roll 55 is a ratchet 62. Pivoted on the rod 33 is an arm v19, also supported by the frames 2|.

63 carrying a spring-pressed feeding pawl 64, co-

operating With the ratchet 62. Pivoted at 65 to the arm 63 is a link 66, slidably supported by a slot 61, on a stud 68 carried by the side 24. A spring 69 holds the link 66 with the right end wall of the slot 61 contacting the stud 68 when the parts are in their normal positions. A retaining pawl supported by the side 24 cooperates with the ratchet 62 to prevent any retrograde movement of the ratchet.

The link 66 carries a stud 1| adapted to be engaged by a slot 12 in the forward endy of a link 13, which is pivoted at 14 to an arm 15, fast on a shaft 16, which shaft is supported by the printer frames 2|. A link 11 is connected to the arm 15 and to a bell crank 18, which is pivoted 'on a shaft The bell crank 18 carries rollers 80 and 8|, cooperating .with plates 82 and 83, respectively, of a double plate cam secured to a printer drive shaft 84, which receives one clockwise rotation during each operation of the machine by means fully illus- .trated and described in the above-mentioned Spurlino and Rauch vPatent No. 2,361,662. As above stated, the notch 12 of the link 13 'is normally disconnected from thestud 1|, but

by means which will be briefly described, when one of the individual listing tapes is 'selected for operation, the 'link' 13 is permitted to rock counter-clockwise .around its pivot 14, whereupon the notch 12 engages the stud 1 I. During an operation of the machine, the cams 82 and 83 rock the arm first clockwise and then counter-clockwise 'to normal position. When the link 13 is engaged with the stud 1 I, the clockwise movement ofthe arm 15 draws the link 66 to the right (Fig. l),

'which rocks the arm 63 and causes the pawl 64 to turn the ratchet 62 and the feed roll 55A to feed the listing tape 44 after the printing has taken place thereon. Such printingon the tape 44 is accomplished by means of type wheels 85, which are set and actuated by means shown and mentioned in the above-mentioned Spurlino and Rauch patent, after which impression means (notjshown herein but fully shown and described in the said Spurlino and Rauch patent) is operated to make a legible printing impression from the type wheels 85 upon the selected tape 44.

There is only one pair of cams 82 and 83, one bell crank 18, one link 11, for all of the individual listing tapes 44. However, there is an arm 15 associated with each of the listing tapes 44 in the machine.

As only one of the listing tapes is'selected for operation at a time, it is necessary to select whichV one of the tapes shall be printed upon and which one of the tape feeding mechanismswill be operated for each operation of the machine. This means is all fully illustrated and described in the above-mentioned Spurlino and Rauch patent.

trated and described in the above-mentioned Spurlino and Rauch patent. Y

There is means herein shown to prevent the machine releasing mechanism from functioning Aif there should be no tape 44 in the machine,

or should the tape be ruptured for any reason at all. This mechanism will now be described.

The machine releasing mechanism per se is not shown in this application but is fully illustrated and described in the above-mentioned Spurlino and Rauch patent. Cooperating with that mechanism is an arm I 0| (Fig. 1) having a spring I 02 normally holding the arm in contact with a stud |03 on a slide |04, slidably mounted on the tie bar 29 and a shaft |05 supported by the sides 24 and 25 of the tape carrying frame.

Pivoted on this shaft |05 is an arm |06 (Figs. 1 and 4) which is engaged by the feed link 66. Also secured to the arm |06 by a hub |01 is an arm |08 heldin contact with a stud |09 by a spring I i0 stretched between the stud |09 and a stud II I on the arm |08. The stud |09 is carried by an arm I I2 pivoted on the shaft |05 and secured to an arm II3 having a bayonet slot I|4 into which projects a pin ||5 on the slide |04. The slide |04 also carries a pin I |6 engaging a slot I I1 in an arm I|8 pivoted on the shaft |05. The arm I|8 has a flange ||9 (Figs. l and 10) engaging the tape 44 opposite an opening |20 in the guide plates 5|.

Normally with the parts in the positions shown in Fig. l when the link 66 is moved to the right to feed the tape 44, the arm |06, and the arm |08 are rocked clockwise, whereupon the spring |I0 rocks thearm II2 and the arm I I3 and causes the vertical portion of the bayonet slot I I4 to engage the stud I I5 on the slide |04. Therefore the stud |03 maintains the arm IOI in the position shown, in which position the machine releasing mechanism (not shown) is free t0 be operated.

However, should the supply roll 45 become exhausted or should the tape 44 break, so that threre is no tape 44 between the flange I|9 and the opening |20, then the spring |02 will rock the arm I0| in a clockwise direction, which through the mechanism shown in the Spurlino andV Rauch patent will prevent release of the machine for a subsequent operation. At the same time, this clockwise movement of the arm I9I, through its engagement with the stud |03, moves the slide |04 to the left, causing the pin ||5 to engage the horizontal portion of the bayonet slot II4, which prevents'any clockwise movement of the arms |I3 and II2.

Should the arm I|8 be permitted to rock counterclockwise during an operation due to failure of paper between the flange |I9 and the opening |20, thus causing the locking of the arms II2 and II3, the flexible connection between the arms |08 and I|2 permits the arm |06 to be rocked while the feeding link completes its movement during such operation.

Combined cover and tape chute The cover and tape or strip chute 60 is rectangular in shape, and shown in section in Fig. 7, the front and bottom being solid and the back and top being open. At the top the cover and strip chute 60 (Figs. 1 to 3) is flared to form a mouth I 3|, and the opening in the back of the mouth is widened as at |32. This wider opening |32 engages ears |33 on a lip |34 of the tape guide plate 51, so that when said chute 60 is in its normal position, shown in Fig. 1, the ears |33 provide a locating means for the chute 60.

The cover and strip chute is supported near its front end by a guide support I 35, (Fig. 5) secured to the bottom of the plate 20. This guide |35 extends across in front of all of the tape printing units and is provided with slots |36 (Fig. 6), there beingone slot for each "of said chutes 60. Near the back of the Ycover and strip chute 60 there VVis a rear guide lill] secured to the bottom of the means of this flange El'i the shield |43 is secured to the front guide |35.

This shield 43 extends across and underneath all the chutes 55 to prevent said chutes from being moved out of position by the operator when sitting at the machine.

Secured to the bottom of the cover and strip chute 55 is a stop plate |55, which is for the purpose of preventing the chute 65 from being accidentally Withdrawn from the machine. When the cover and strip chute i! is drawn forwardly (to the left as viewed in Fig. 1), the left end of the stop plate |53 contacts the rear side of the guide |35, as shown in Fig. 5, and prevents the chute 58 from being fully Withdrawn from the machine.

To permit the operator to fully Withdraw the cover and strip chute 6D from the machine, the bottom iid of the shield |63 is provided with openings |5| beneath each of said chutes 5S and the operator may, by putting his finger through this hole l5| and pressing the stop plate |58 upwardly until the front end of the same is in line with the slot |35, fully and completely Withdraw the chute 55 from the machine.

To assist in drawing the cover and strip chute 55 out of the machine, the front part of the cover and strip chute has secured thereto a curved plate |52, having integral therewith a hand puli or knob |53.

To-latch the cover and strip chute 55 in position, there is secured to the front of each chute a plate |55 having bent-up ears |55, one of each side of said chute 60, to support a stud |55. Pivoted on this stud |56 is a pair of latches |51, connected to operate in unison by a yoke |58. A torsion spring |59 Wound around the stud |55 and engaging one of the latches |51 causes the pair of latches |51 to be held in engagement with a rod |55, which is supported by the front sides of the channels 22 and extends across all of the printing units.

To draw the cover and stop chute 60 outwardly, t0 inspect the printed tape M or to tear 01T the printed portion thereof, the operator merely grasps the knob |53 and pulls toward the left as viewed in Fig. l, whereupon the latches |51 are cammed olf the rod |60.

When the cover and strip chute (it is pushed back into normal position again, the latches |51 are rocked counter-clockwise against the action of the spring |59 until the chute is in the position shovvn in Fig. 1, whereupon the spring |58 causes the latches |51 to engage the rod |65 to retain the chute in its operative position.

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