Patented a. 19, 1937 UNIT'ED STATES PATENT OFFICE" Ma: Gal-bell, Chicago, Ill.. asalgnor to Victor Adding Machine Company, Chicago, 111., a cor poration of Delaware Application July 15, 1938, Serial No. 90,691
dOlaimsQ (01. 197-128) This invention relates to paper drive means for adding machines, and is more particularly directed to means for feeding papers independently of the platen.
6 Heretofore, multiple strips of paper have been employed, which were fed simultaneously by the platen, resulting in a rather hard operation of. the machine, andthe present invention is directed to a solution of this problem. It is also 10 directed to means for selectively conditioning the drive means to move one of the papers a greater distancethan the normal feed.
The chief object of the invention is to pro vide an improved paper drive for adding machines and the like.
Another object. is to provide simple and eflicient means for feeding multiple strips of paper independently of the platen, and for positively feeding one paper upon the operating stroke 20 of the machine, and to feed another paper upon the restoring stroke of'the machine.
And a further object is to provide means for conditioning the drive means to feed one paper a greater distance than its normal feed.
Other objects and advantages will become apparent from the specification and drawings. Referring to the drawings: Figure 1 is a longitudinal partial sectional view' of an adding machine, showing my invention ap- 30 plied thereto.
Figure 2 is a view similar to Figure 1, showing a changed position; and
Figure 3 is a cross-sectional viewtaken the line 3-3 of Figure 1.
35 The invention is shown as applied to a Victor adding machine, and only the parts more particularly associated with the present invention have been illustrated and described.
The machine is originally provided with a 40 rocker plate s which is pivotally carried on the side plates ii and Ha by means-oi studs II. The rocker plate is connected to an upright member I! carried for reciprocating movements in bearings l6, and, l! secured to theside plate ii.
45 This upright member l3 is'operatively connected to the actuator shaft it of the machine, by means of a bell-crank ll carried by a stud IS on the side plate H, and has a leg 19' provided with an elongated slot 29 which receives a pin 2i secured in the upright member l8. Theother leg 22 or! the bell-crank i1 is connected to a link 23 by a pin 24 and the other endof the link is connected by a pin 25 to an arm v26 fixed to the actuator shaft l8. The rocker plate l0 normally carries a pawl 2! pivoted thereto, at 28,
39,, to the take-up roll 44.
and which is urged by a spring 29 into engagement with a ratchet-wheel 30 secured to the platen ll, carried on a shaft 32 in the side plates ii and Ho. This pawl 21 serves to rotate the platen for a step-by-step movement in the usual 5 manner, but in this instance, it merely serves to present dilferent portions of its surface to receive the impact ofthe type bars (not shown) and the paper drive means is independent of the platen, as will be presently described.
The rocker plate i0- is provided with ears Ilia which carry a pawl 33 on a pin 34, and a spring 35 urges the pawl into engagement with a ratchet-wheel 36 that isflxed to a feedroll 31 carried on a shaft 38 supported in the side plates II and Ila. The feed roll 31 has a companion roll 39 carried on a shaft 40 which is also supported in the side plates ll-lla, and receives a record strip therebetween, to feed the same. The feed roll 31 also has a sprocket 2o gear 4| fixed thereto and a chain 42 that extends to a sprocket wheel 43 flxed'to a take-up roll 44 carried on a shaft 45 supported in the side plates H and Ila. Between the take-up roll 44 and the sideplatei I is a friction clutch s, which compensates for the increasing size of the takeup roll in the usual manner, as the recordstrip is wound therearouncl.
'fhe record strip roll A. on which a permanent record is-kept, is carried on a shaft 41 supported in the'side plates II and Ho, and the free end of the record strip is guided over a plate 48 and extends through an opening 48a therein and under an arcuate portion 48!) thereof that is positioned below and in spaced relation with the platen ll. The free end of the record strip also passes in front of the piatenover a paper table 49 and through a guide member 50', and Y between the feed roll 31 and its companion roll Another paper roll B, which is adapted to serve as receipt slips when severed, is carried on a shaft 5| supported in the side plates II and Ila, with the free end thereof directed between a feed roll 52 and a companion roll 53, and extends in front of the platen 3! over the record strip and through the guide member 50. The feed roll 52 is supported on a shaft 54 carried in the side plates and ila, below the. platen 3i, and has a, ratchet-wheel 56 fixed thereto which is normally engaged by a pawl 56 pivotally carried at 51 on an arm .58 that is pivotally carried on a stud -I59 securedto the side plate I i.
The pawl 56 is normally urged into engagement with'the ratchet-wheel by a spring 60, and
the arm 58 is normally urged upwardly by a spring 6| fixed thereto, and which extends around the stud 59 and is secured at 62 to the side plate II. The arm 58 is in the form of a bell-crank and has an integral upwardly extending portion 63 which is urged by the spring 6| into engagement with a depending arm 66 extending from the rocker plate Ill. The arm 58 is provided with an extension 55 at its free end portion that is adapted to engage a slide 66 carried on the side plate ll under the control of a depressible key 61. The slide 66 is provided with elongated slots 68-68 adjacent each end thereof through which the studs 6863 extend and which studs are secured to the side plate II. The slide 66 is also provided with a cam slot 10 which receives a follower H secured to the stem 12 of the key 61, which is guided at its upper portion in a plate 13 of the keyboard of the machine, and its lower end is guided on a stud 14 that extends through a vertical slot 15 in the stem 12 of the key. The stem 12 of the key 61 is also provided with a lip 16 that is adapted to be engaged by a pawl 11 pivotally carried on the side plate II, by a pin 18, and which pawl is urged toward the stem 12 by means of a spring 19. This pawl 11 is in the form of a bell-crank and'has a depending member 88 pivotally carried thereon at 8|, and normally depends into the path of an upwardly extending ear 82 on the link 23. 7
Upon the movement of the actuator shaft i6, the link 23 is carried forwardly, which rocks the bell-crank l1 and forces the upright member l3 upwardly to rock the rocker plate II and carries the pawl 33 upwardly therewith to effect a turning movement of the ratchet-wheel 36 and feed roll 31, with the companion roll 38 to feed the record strip and through the chain 62, will effect a turning movement of the take-up roll 84.
' The upwardly rocking movement of the rocker plate l0 carries the depending arm 64 therewith for a counter-clockwise movement away from the upwardly extending portion 63 of the arm 58, as shownin dotted lines Fig. 1, and the arm 58 will be urged upwardly by its spring 6| until the extension 65 thereof engages the slide 66. During this upward movement of the arm 58, the pawl 56 will ratchet against the ratchet-wheel 55 without effecting its turning movement and a turning movement of the feed roll 52. Upon the restoring'movement oi the actuator shaft IS, the link 23 will be carried rearwardly to its normal position and rock the bell-crank l'l downwardly which will carry the upright member I! downwardly therewith to restore the rocker plate I. to its normal position and carry the pawl 33 thereon fora ratcheting movement against the ratchet-wheel 36 without effecting movement of the record strip A The restoring movement of the rocker plate It carries the depending arm 66 therewith for a clockwise movement to engage the extending portion 63 of the arm 58 and effect a downward rocking movement of this arm 58 with the pawl 56 thereon to turn the feed roll 52 and companion roll 53 to effect a feed of the cent the side plates As the key 61 is depressed, the follower H on the stem 12 thereof, will effect a sliding movement of the slide 66 by engagement with a cam slot 1.0 therein, to position the same out of the path of the extension 65 on the arm 58 and permit this arm to be urged upwardly by its spring 6|, as shown in full lines Fig. '2. When the am 58 is in this upward position, the movement of the depending arm 64, upon the restoring movement of the rocker plate I, will then effect a greater movement of the arm 58 and pawl 56 .to rotate the feed roll 52 a greater distance which will feed the paper B a greater distance than its normal movements. When the key 61 isdepressed, (Fig. 2), the pawl 'l'l will engage the extension 16 of the key stem I2 and withhold the key in depressed position with the slide 66 out of the path of the extension 65 on the arm 58. As the actuator shaft "3 is restored to its normal position, the link 23 is carrledtherewith, and the ear 82 on the link will engage the depending portion on the pawl 11 and efiect a rocking movement of the pawl to release the same from the extension 16 of the key, and permit the key to be restored by its spring 83 to normal position, with the slide 66 again positioned in the path of the extension 65 on the arm 58. It will be noted that the ear 82 trips the pawl TI to release the key and slide at the time the arm 58 has been forced downwardly below the slide 66 by the depending portion 64 of the rocker plate I, so that the slide 66 is then in' the position shown in Fig. 1, to limit the normal movements of the arm 58 and pawl 56 to feed the paper B the same distance that the paper A is fed.
The paper 3 is retained against the feed roll 52 by the companion roll 53, which has its shaft 53a1journaled in a pair of arms 53b carried adjall-l In on a shaft 530. These arms 5317 each have a spring 53d fixed thereto and to the side plates Ill la, to maintain a constant pressure of the companion roll 53 against the feed roll 52. The shaft 53c has a lever 53c fixed to one end thereof, which is manually gripped to rock the companion roll 53 away from the feed roll 52 to insert the paper B therebetween.
With this arrangement of the paper drive means, the record strip A and the paper B are fed in front of the platen 3| and independently thereof, and the platen is partially rotated upon each operation of the machine to expose a different surface thereof to receive the impact of the type bars (not shown).
While the record strip A and paper B are positioned one in front of the other to be simultaneously printed upon with each operating stroke of the machine, the record strip A is fed upon the forward stroke of the actuator shaft and the 4 paper B is fed upon the restoring stroke of the actuator shaft.
I claim:
