'- 8 Claims. (01.19 132) This invention relates to improvements in adding machines, and has more particular relation to those, which, in addition to accumulating amolmts in a totalizer, make a printed record of all transactions and issue a receipt for each transaction. I

It is an object of the present invention toprovide mechanism for severing a strip of paperafter amounts recorded thereon have been totaled.

A further object is the provision of mechanism conditioned upon the total printing operation of the machine and released at near the completion of the operation for severing a paper strip which has amounts and the total of the transactions printed thereon. V

A further object synchronized with the paper cut-ofi mechanism for efiecting a step-by-step movement of the auxiliary paper strip after each printing operation of the machine and for effecting a greater movement to the paper and conditioning the paper cut-oif nieans during the taking of the ,total printing operation.

A still further object is the provision of a haper will of the operator and automatically released "at near the completion of operation of the machine for a spring-impelled severing action of the auxiliary paper strip and with rebound means meeting therewith, which serves to normally restore severing operation. v

Still a further object is the provision of feeding means for the auxiliary paper strip arranged to yieldingly engage the strip for feeding the same and to be manually separated to admit of the insertion of the strip.

And a further object is the provision of a cutoff mechanismwhich is arranged as a shear for severing the auxiliary paper strip.

:fReferring to the drawings, only' so much of the e is shown as, is necessary for a clear understanding of the operation of the invention and its connectionswith the operative parts of the machine, and in which:

Figure 1 is a'medial sectional view of the rear portion of the machine and'carriage with my improved paper cut-oif-and feeding mechanism attached thereto.

Figure 2 is a medial sectional view similar to Figure 1, illustrating a changedposition; and

Figure 3 is a detail plan sectional view taken substantially on the line 3-4 of Figure 1.

My improved mechanism is illustrated as being 55 carried on the carriage of the adding machine is the provision of mechanism cut-off mechanism positively conditioned at th'e means of a bell-crank 2'! and a link 28.

the cut-off means to its normal position after the and o peratively connectedfor movement with the operating mechanism of the machine, and having manually controlled means for positioning the parts'i'to condition the mechanism thereof for operatipfn with the operating mechanism of the 5 machine.

machine herein disclosed comprises side wall on which a carriage l I is secured, and which arria'ge supports a platen I2 on a shaft mechanism I5 for the strip R fed from the record A paper guide .I 6 serves to guide the record strip R around under the platen so that it will only engage the exposed front portion of the platen 15 adjacent the printing elements P and thence throughi a guide l8 to the feed mechanism I5.

As disclosed in the drawings, the feeding mechanism I Sgis controlled .by a pawl I9 which is pivoted at "on a rocker member 2| supported at 22 20 on the carriage II; This rocker member 2| is operatively' connected at 23 to a vertically disposed reciprocable member 24 guided in bearings 25-25 carried on the side wall Iil of the machine and this reciprocable member 24 is operatively con- 25 nected to the actuator shaft 26 of the machine by The rocker 2i is arranged to be rocked in a counterclockwise direction from Fig. 1 position to Fig. 2

position when the actuator shaft 26 is rocked for- 3Q" ingadiiferent portions of the platen in printing position. When the rocker 2| ,is-rocked in a counterclockwise direction, the pawl I9 will then engage to turn a ratchet wheel 3| to. .feed the record strip R and upon its resto .ng movement. it will ratchet thereagainst pre" ratory to the next feeding operation. I

My improved mechanism is arranged to be operatively connected with the rocker 2| and the reciprocahle member 24' which causes its movements. Thismechanism is arranged to normally so feed an;auxiliary strip of paper .A in uniform relation or the same distance as therecord strip R is being fed during the normal printing operations of the machine. This auxiliary strip A is fed from a roll 32 carried on the side walls It of u the machine and directed through a trough 33 below the paper table or guide l3 and thence over the exposed portion of the record strip R. ad-

jacent the printing elements P and through a feed mechanismgdesignated as a whole as 34 and over the paper table l3. The feed mechanism 34 comprises a roller 35 pivotally supported on the paper table i3 and a companion roller 33 pivotally supported at 31 on a plate 33 which is pivotally carried on the paper table I3 at 33, and which plate-has springs 43coacting therewith to normally urgethe companion. roller 33 into engagement with the roller 35. The plate 33 is provided with a pair of finger grips 4| to rock the plate on its pivot 33 with the companion roller 33 out or engagement with the roller 35 so as to insert the auxiliary paper strip A therebetween and to be gripped thereby when the plate '33 is released. i

The. roller 35 has a ratchet wheel 4 fixed thereto against which a pawl 43 is normal] urged by means of a spring 44 and which pawl carrled at 45 on an, arm 43 pivoted at .4! to the carriage The arm 43 is in the form of a bellcrank having an integral downwardly directed portion 43 which is normally in the path of an car 43 carried on the rocker 2|, so that the movement of the rocker willefl'ect movement of the bell-crank and pawl 43. 'A torsion spring 53 is carried by the pivot 41 and has one end engaging the arm 43 of the bell-crank and its other end engaging the carriage ll, so as to normally urge the arm 43 and pawl 43 upwardly, and the movement of the rocker member 2| with the ear -49 thereofaway irom the portion 43 of the arm 43. permits the spring 53 to carry the arm .43 and pawl 43 upwardly fer a ratcheting action against I rocking movement of the arm 43 and pawl 43 to effect aturning movement of the ratchet wheel 42 and roller 35 to feed the auxiliary paper strip A.

During the upward movement of the reciprocable member 24 upon the forward stroke of the actuator shaft 23, the record strip R is fed and during the restoring movement of the recipro- :c'able member 24 upon the restoring stroke of the auxiliary strip A for a greater distance oi.

ll tl'ia movement than the distance it is fed during normal-operations ot the machine; and, at which time, the severing means is conditioned and brought into play so as to sever the auxiliary strip A.

The severing means is in the form of a shear comprising a swingable blade 5| which has one end thereoi pivoted at 52 on'a bracket 53 secured to the paper table l3 and its other end is provided 7 ownwardly directed ear 54 to which'a link as 1 pivoted at is and which link has its other end pivoted at 51 to a bell-crank 53 pivotally carried on the platen shaft |2a.' The leg 53 of the bell-crank 53 carries a depending bellcrank member 33 pivotally connected thereto at 3| and the arm 33a of the bell-crank member is normally in the path of the leg 53 of the bellcrank 53 and serves to limit its movement to limit the movement of the pawl 43 during a step-bystep movement of the feed roller 35. The member 33 has a connecting link 32 at it's free end and which link is connected to a bell-crank 33 carried at 34 on the side wall l3 of the machine. The bell-crank 33 extends into the path of a pin 35 carried by a depressible key 33 positioned in the keyboard 02 the machine, and whioh key is spring-urged to normal position. The key 33 is also arranged to be locked in depressed position and is provided with a notch 33a that coacts with a slide 31 supported in a bearing 33 carried by the side wall |3zof the machine. The slide 31 has a spring 33 secured thereto and to a pin I3 carried by the side wall l3. and which spring yieldingly retains an ear 31a of the slide 31 in sliding engagement with the key 33 preparatory to engaging a notch 33a therein. An arm Ii is pivoted at 12 to the slide 31 and is rockably sup ported on the side plate M at I3 with its lower 'endin the path of movement of a spring-urged dog l4 carried on the link 23. v

- As thus far described, it will be noted that the depression of the key 33 (dotted lines Fig. 1), will cause a clockwise movement of the bellcrank 33 and a pull on the link 32 to swing the bell-crank member 33 forwardly on its pivot 3| without eilectingmovement of the bell-crank 53 on which it is carried. This swinging movement of the member 33 carries 8. lug thereof under an ear I3 of a rockable member I! pivotally carried at 13 on the side wall M of the machine, and which member has its'other end operatively connected at 13 to the reciprocable member 24.

When the machine is operated, the reciprocable member 24 will be carried upwardly by movement of the bell-crank 21 and link 23 under the control of the actuator shaft 23, as above described. and this upward movement of the reciproeable member 24 will carry the pivot I3 upwardly therewith to rock the rockable member 11 on its pivot l3 which rocks the ear 13 downwardly with the bell-crank member 33 therewith by reason of the engagement of the lug 15 thereof and ear I3. This downward movement of the bell-' crank member 33 causes the bell-crank 53 to rock in a clockwise direction on the platen shaft |2a, which through the link 55, carries the blade 5| tor a rearward swinging movement on its pivot 52. This rocking movement of the bellcrank 53 carries an ear 33 formed on the leg 53 thereof into the path of a notch 3| provided in a dog 32 which is pivotally carried at 33 on the carriage II, and which dog is urged toward the ear 33 by a spring 34 fixed thereto and to the carriage H. The notch 3| oi the dog 32 is then urged over the ear 33 of the leg 53 of the bellcrank 53 to retain the same and bell-crank member 33in the position to which they have been moved under the control of the rockable member upon the movement of the reciprocable member 24, While the bell-crank 53 is retained in the position above described, the arm 33a f the bell-crank member 33 is carried out of the path of the leg 53 of the bell-crank 53 to permit of a greater movement of the bell-crank 53 and pawl 43 for a greater turning movement of the feed roller 35. At this time, the blade 5| is retained out of the notch 88a of the key 96 which permits the key to be spring-urged to normal position. When the key is released, the spring 85 restores the bell-crank member 60 with the lug out of engagement with the ear 16 of the rockable member 11. When near the limit of its restoring movement, the ear 49 carries a portion 86 which is brought into engagement with the dog 82 to release the notch 8i thereof from the ear 88 of the leg 59 which releases the bell-crank 58' and pemiits it to be urged by a spring 81 fixed thereto and to the carriage l I. This movement of the bell-crank 58 carries the blade 51 therewith for a swinging movement on its pivot 52 and with the cutting edge 5|a of the blade over a companion edge 88 secured to the paper table I 8.

In order to maintain a constant tension on the blade 5|, a spring 89 is arranged to engage the top surface thereof and which spring is ca ed ona pin 90 that is pivotally supported at 9 on the paper tablel3, and which pin has its 0 her end extending through an opening 92 in the lade 5i. This spring 89 serves to retain the blade in engagement with a shelf 98 carried by the paper table andwhich shelf is provided with a slot 94 to permit'the pin 90 to extend through the blade 5| and to freely ride within the slot. This tension of the spring 89 serves to retain the cutting edge 5|a of the blade for engagement with the companion edge 88 secured to the paper table i3.

It will be noted that the leg 59' of the beilcrank .58 has a relatively light tension spring 95 secured to the underneath edge thereof and which spring has its other end anchored to the carriage and serves as a restoring spring to restore the bell-crank 58 after the bell-crank and blade 5i have been released to sever the auxiliary strip A under the control of the spring 81f This relatively light tension spring 95 is of just sufficient tension to retain the bell-crank 58 and blade 5| in its normal position while the spring 81 is in its normal'position.
