This invention relates to improvements in web feeding mechanisms for cash registers and calculating machines.

The object of the invention is to provide an improved printing mechanism, and particularly the mechanisms for controlling the operation of web feeding mechanisms.

A specific object of the invention is to provide a webv feeding mechanism having tension rollers which grip the web at both sides thereof to facilitate the tearing of the web from either the right or the left.

Another specific object of the invention is to provide a web feed mechanism with tension rollers, one gripping the web at each edge thereof, and each tension roller being independently actuated by a resilient means so that each tension roller can efiectan independent gripping of the web.

Another specific object of the invention is to provide a receiptv printing mechanism with a stationary tear-off knife, and to provide the web feeding mechanism with two independently operable tension rollers which are adapted to grip the web at each edge thereof so that, when the operator tears the receipt from the web by .pulling the web against the stationary tear-off knife, the operator may tear. either from the right or from the'left.

. Another object of the invention is to provide a novel on-and-off means whereby the operator may throw the web feeding and printing mechanism on or off at will.

Still another object of the invention is to provide a web shifting mechanism which is simple in construction and operation, whereby the web may be shifted from a reading position into a printing position, andvice versa.

With these and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, a preferred form or embodiment of which is hereinafterrdescribed with reference to the drawings which accompany and form a part of this specification.

The invention is shown applied to a machine of the type illustrated in United States Patent .No. 2,209,763, issued to E. Breitling on July 30,

Machines of the type illustrated in said patent are usually provided with a series of settable levers H, H! and 20 0 (Fig. 1) and each lever is geared to a type wheel for printing data upon an issuing receipt. Indicators and 286 of the usual construction are provided. The machine is also provided with release keys 2m, and special counters 325. The mechanism is enclosed in a cabinet 34, resting on a cash drawer base 33.

An electro printing device is provided for printing various data of a descriptive or advertising nature upon the face of the issuing strip. The type wheels are inked by an endless ribbon supported by a removable frame, which may be easily and quickly removed from the machine when it is desired to change or adjust the inking ribbon. An ink well is provided to constantly re-ink the ribbon. The electro printing and receipt feeding mechanism may be disabled when desired by means of a manipulative device which projects through the cabinet of the machine near its left side.

Printing mechanism The machine is provided with a printing mech anism mounted on the left side frame 3|, which printing mechanism records data on a receipt 410 (Fig. 3).

The receipt paper is fed from a supply roll 413 (Fig. 3), rotatably mounted on a stud 414, carried by the left side frame 3|. The Web of the receipt paper 415 is fed from the supply roll 413 around an ink well 476 and over aguard 411, between feed rollers 5H], 5| l, and 5H, 512 hereinafter described (see also Fig. 5), and through a chutel'lB (see also Fig. l). A stationary knife 459, mounted on the chute 418, is provided for tearing off the receipt 410 after the receipt has been issued from the machine.

An endless ribbon 419 is provided for expediting the printing of the data from a group of type wheels mounted on the stud 92, from manually settable date printing wheels, and from type wheels to identify the machine by a number or symbol, mounted on a stud 491.

Receipt printing mechanism To record the impressions on the receipt paper from the type carriers on the studs 92 and 491, a.

hammer 480 (see Figs. 3 and 4) is provided. The hammer 480 is provided with a platen 481, for printing from the type carriers on the stud 92, and a platen 482 for printing from the type wheels (not shown) on the stud 497. The hammer 480 is notched, to receive the forward end of an arm 485 (Fig. 4), and a stud 486, extending through the hammer 48D and the free end of the arm 485, provides a pivot point for the hammer 480. The arm 485 is pivoted on a stud 481 carried by the side frame 31 of the machine. The arm 485 has, mounted thereon, a square stud 488, which normally lies in the path of a second square stud 495 (see Fig. 4) carried by the forward end of a link 495. The square stud 495 is normally engaged by a lever 4S9 pivoted on the stud 481, the lower end of which lever is provided with an antifriction roller 4911, held in engagement with a cam 491, on a cam shaft 57, by a spring 492. I

Operation of the machine with the square stud 4515 overlying the square stud 488 operates the printing hammer 481 in the following manner. Counterclockwise rotation of the cam 451 rocks, by engagement with the antifriction roller 4 911, the lever 489 clockwise against the action of the spring 492. Clockwise rotation of the lever 485 carries the stud 485 against the stud 488, thus rocking the arm 4B5clockw'ise to lower the platens 4 81 and 482 tocarry the web 4T5 and the ribbon 419 against the type carriers to make an impression on the receipt paper. After the impression has been made, and when the cam #91 passes beyond the roller 490, the spring 492 restores the hammer 485 into its original position.

The hammer 451i is provided with aguide slot 493 engaging a stud 494 carried by the left side frame 31. The slot 493, cooperating with the stud 455, guide the hammer in a vertical path when the arm 485 is rocked clockwise to make impressions.

The square stud 495 is movably mounted with the link 4% for disabling the printing hammer when desired. When moved leftwardly from the position shown in Fig. 4, the stud 495' is in its disabled position, and therefore, when the earn 491 rock the lever 489, the stud 495 does not engage the stud 488; therefore the arm 485 is not operated. When it is desired to operate the hammer 4811, the square stud 455 is moved to the right (as shown in Fig. 4) until it comes over the stud 488 inthe manner described hereinaf-te-r.

Receipt feed'cmd electro mechanisms" "tfo device prints various data of descriptive, or

advertising, nature on the face of the succeeding receipt. The receipt feeding and electro mechanism will now be described.-

Referring to Figs. 2 and 3, secured to the shaft '31 is a partial gear 551, the teeth of which cooperate with the teeth in a full gear 552 loose on a stud 553, and said gear 502 meshes with a full gear 554', loose on the stud 52. The gear 504 meshes with a full gear 5115 rotatabl'y supported by the beforeme'ntioned stud 491 secured in the side frame 31. The gear 555 meshes with a gear 555 secured to a shaft 501 mounted between the side frame 31 and a printer plate 458. Also secured to the'shaft' 501 is a gear 5118 meshing with mounted on the side frame 31.

41 a gear 509 rotatably mounted on the stud 491. The gears 555 and 505 are located adjacent the edges of the receipt paper web 475. Secured to the side of the gear 555 is a feed roller 51%, and secured to the side of the gear 509 is a feed roller 511. The feed rollers 51!] and 511, coacting with pressure rollers 512, 512, one provided to engage each of the feed rollers, cooperate to feed the receipt web 4'15. Since the feed rollers and the 1 pressure rollers engage the receipt paper web at its edges, the receipt paper will be fed through the machine in a straight line. Each pressure roller 512 is independently mounted on a bell crank 513 pivotally mounted on the stud 4514 A link 514 connects each bell crank 513 to a rod 515. The ends of the rod 515 are loosely engaged with the links 514 to permit independent action of each link 514 and each bell crank 513, so that the pressure rollers 512 can receive independent movement, so that a firm contact will be made'with their respective feed rollers. A single spring 515 is connected at one end to the rod 515 midway between its two ends and at its other end to a rod 517. The rod 511' is carried by two arms 518, 518, which arm are connected together by a yoke The yoke 5155 supports a printing platen 525, which platen is provided to take impressions from a rotatable electro roll 521'. The yoke 519 is held against an adjustable screw 522, carried by a bar 5242 connecting an arm 524 and an arm 5241, both arms being pivoted on a stud 526. A spring 523, stretched between a stud on one arm 51% and a stud in the arm 524, maintains the yoke 519 in contact with the adjustable screw 5.2. A spring 521, connected to a stud on the arm 524, maintains a stud 525 on said arm 524 in engagement with a cam plate 528 rotatably mounted on a stud 530.

The cam 528, in cooperation with the stud 525, maintains the arm 524 and the adjusting screw 522 in such contact with the yoke 519 as to maintain the electro printing platen 521] in printing position. When the parts just described are in the position shown in Fig. 3, under control of the cam plate 528, the rod 511 is located in slots 531 in such relation to the left-hand ends of said slots as to permit the spring 51:5, acting through links 514, to independently maintain the pressure rollers 512, 512 in contact with their respective feed rollers 511] and 51 1.

With the pressure rollers 512, 512 resiliently held against the feed rollers 510 and 511, when the machine is operated, the main cam shaft 3'1, through the gears 551, 552, 504, 5115, 506, 5113, and 5119 and the feed rollers 511] and 511, feeds the receipt paper out of the machine. During this operation, the gear 55?. rotates the electro 521 to cause the advertising matter to be printed on the receipt paper.

In order to provide time for the printing hammer 4511 to take its impression before the receipt is fed out of the machine, the gear 551 has a section of its teeth omitted, and a plate 532 is secured thereto, which, in cooperation with the cut-away portion 553 on the gear 552, maintains the gear 552 against rotation until the plate 532 passes beyond the cut-away portion 533. After the cut-away portion 533 is free from the gear 5112, the partial gear 501, acting through the train of gears 552 to 5119, rotates the feeding disks 511i and 511. During this operation, gear 552 rotates the electro cylinder to make the impressions on the receipt paper for the next r'ec'eipt to be issued.

Printer and feed throw-017 When it is desired'to operate the machine without issuing a receipt, the printer platen 480 and the feed mechanism are disabled, by rotating the 'cam plate 528 prior to a machine operation. To facilitate the adjustment of the cam plate 528, a knob 536 is provided thereon, which knob projects through the cabinet of the machine, as illustrated in Fig. 1. The full-line position of the knob 536 (in Fig. 4) indicates the position which the cam plate assumes when the printer hammer and the feed mechanism are operated. As shown in this figure, the square stud 495 lies over the square stud 488, and therefore, when the machine is operated, the square stud 495, acting on the square stud 488, operates the printing hammer in the manner described above. If it is desired to disable the printing mechanism, the operator moves the knob 536 to the dot-anddash line position shown in Fig. 4. This rotates the cam plate 528 and causes a cam surface 53! thereon to coact with the stud 525 and allow the movement of the arm 524 counter-clockwise under action of the spring 521. The rotation of the .cam plate 528 is arrested when a node 539 thereon comes into contact with the stud 525. Counter-clockwise movement of the arm 524, through, the spring 523, lifts the arms 5I8 to move the electro platen 528 into ineffective position. Simultaneously, the arms 5I8, acting on the rod 5ll, shift the links5l4 leftwardly (Fig. 3) to rock the bell cranks 513 counter-clockwise to raisethe pressure rollers 512, 5I2 out of engaging position with the feed rollers 5m and 5| I. Also simultaneously with the counter-clockwise movement of the rod 5", the link 495 is moved leftwardly to move the square stud 495 from the position shown in Fig. 4 tothe position in which the square stud 495 no longer overlies the square stud 488. Subsequent operation of the machine when the main cam shaft 31 is rotated causes the lever 489 to rock the square'stud'495 idly, and therefore the printing hammer 48!! will not be operated to make an impression. Also the operation of the feed rollers 5H] and 5 is idle,

since the tension rollers 5l2 are not engaged therewith.

While the form of mechanism shown and described herein is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to one form or embodiment disclosed herein, for it is susceptible of embodiment in various other forms.
