GENERAL DESGRIPTION As previously stated, this divisional application is .directedparticularly to therecord material,the mounting and control thereon-and also the impression means and its control, adapted for use in a ,cash register or adding ,machine.

The record material, a ,fragmentary portion of which .is shown in Fig. .5, is comparatively .wide, and is divided into nine vertical columns, the extreme lefthand column of which is considerably larger than .the other eight columns, and is used for the printing of the ledger numbers and all other identifying data, as well as amounts. "In addition, the lefthand column :is used :for the autographic entering of identifying data opposite the printed entries.

Likewise all totals and sub-totals are printed in'this wide lefthand column and when the .ma-

chine is used as an adding machine, it is possible to print any amount desired in this lefthand column.

When the machine is .used as a cash register,

cash and charge items cannot be printedin the amaze;

lefthand column, and therefore must be printed in one of the other eight columnar divisions located to the right thereof. Also, when the machine is used as a cash register, the received-onaccount and paid-out items may be printed in the lefthand column, or in any other desired one of the eight columns of the record material. However, no-sale items are invariably printed in the lefthand column.

The web of the record material is contained on a supply roll and is unwound therefrom and threaded around various guide rods, between the impression mechanism and the printing mechanism, and thence onto a receiving roll. The entire record material mechanism, including the supply roll, the receiving roll, guiding means therefor, and the impression platen, is mounted in a framework which is rockable from a normal or reading position and return, to move the record material to and from printing position without the necessity of sliding the web of record material over stationary guides and supports. When the record material is in reading position, the last few entries thereon are visible through an opening in the closure of the cabinet, which closure gives access to the record material mechanism. Likewise, the autographic portion of the record material is accessible through said opening for the autographic entry of descriptive data thereon.

The rockable framework which supports the record material is in turn supported by a framework, which is removably mounted in the front of the machine and which is accessible through the closure above mentioned. The closure, which gives access to the record material mechanism, is not only locked in closed position, but is automatically unlocked when a total control slide (not shown in this divisional application) is moved to either Read total position or Add and Reset position. When the closure is open the removable framework may be easily removed from the machine, and as this framework carries the rockable framework, the entire record material assembly, including the supply roll and the receiving roll, may be quickly and conveniently removed from the machine for the changing of record material, or for the making of adjustments to the record material mechanism.

As the record material framework is rocked from reading position to printing position, a portion of the guiding means for the web of the record material is momentarily retracted, to release the tension on the web of said record material, and while the tension is thus released the automatic means for rotating the record material receiving roll functions to line-space the record material. A key located on the lefthand side of the keyboard is provided for actuating mechanism which rotates the record material receiving roll for manually advancing or line-spacing said record material.

DETAILED DESCRIPTION Machine framework and operating mechanism The mechanism of the machine is supported by two main frames 60 and BI (Figs. 1 and 6) secured to a base which is not shown in this divisional application. All of the mechanism of the machine is also enclosed in a suitable cabinet 69, a portion of which is shown in Fig. 1.

A conventional type of electric motor (not shown herein) drives a main shaft E30 (Fig. 3) one clockwise revolution for each operation of the machine.

PRINTER Type wheels Type wheels 3H! for the four lower order amount banks are supported in a shiftable framework which is positioned under the influence of column selecting keys to select the different columns of the record material (Fig. 5) for the entering of various items.

There is only one type wheel 1H9 shown in this divisional application. The mechanism for differentially positioning the type wheels 3I9 and the shiftable framework for shifting the type Wheels is not shown in this divisional application, but is fully illustrated in the parent application, Serial Number 430,214.

Record material mechanism The supply and receiving rolls for the record material, shown in Fig. 5, are supported in a framework which is removably supported between the main frames of the machine, and which is located at the front of the machine where it is accessible through a closure in the cabinet portion of the machine. The closure giving access to the record material is locked in closed position when the total control slide (shown and described in the parent application, Serial Number 430,214) .is moved to either the Read total position or the Add and Reset position. Therefore, the record material is accessible only to those having keys to a lock in the total control 1 slide, which look is used for locking the slide in either Register position or Lock-register posif 315 tion.

, said opening being covered with a transparent The last few items entered on the record mate- 3 rial are visible through an opening in the top part of the closure giving access to the record material,

material such as glass or pyralin. The extreme lefthand portion of the record material is reserved for the autographic entering of various data, and an opening in said transparent material gives access to this portion of said record material for this purpose.

Referring now particularly to Figs. 1, 2, 3, 6,

and 9, the removable framework for supporting the record material supply and receiving rolls comprises a right plate 126 and a left plate 121 connected in fixed relationship to each other by a rod 128. Trunnions formed by opposite ends of the rod 128 engage curved slots 129 in each of two similar plates 130 and '13! secured, respectively, to the right side frame BI and to the left side frame 60. Similar extending legs of the plates 12B and 12'! have identical inverted V- shaped notches I32 and 133 adapted to engage, respectively, the circumference of similar hubs secured in axial alinement with each other in the frames 69 and GI, said hubs providing bearing supports for a shaft 134. The rod 128, in

cooperation with the curved slots 129, forms a I35 (Figs. 1 and 6) pivoted on studs 136 in plates 126 and 121, are urged clockwise by Springs 131 into engagement with stationary studs 138 in the frames 60 and 6|, to latch the record material framework in operating position, as here shown. 4

To remove the record material framework from the machine or to swing said framework to a more accessible position for the removal of the printed portion of the record material wound on the receiving roll, bent-over finger-pieces 139 on the two latches 135 are grasped, and said latches are rocked counterclockwise, as viewed in Fig. 1, against the action of the springs 131, out of en'- gagement with their respective studs 138, after which the entire record material framework may be rocked outwardly or counterclockwise, the rod 128 andthe slots 129 forming a pivot for said framework until similar projections 14! on downward extensions of the plates 125 and 121 come into contact with the studs 138 to terminate rocking movement of said framework and to hold said framework in an accessible position. If it is desired to remove the framework from the machine, the rod 128 may be lifted out of the open upward ends of the slots 12-9.

A supply roll 142 (Figs. 2, 3, 6, and 8) is rotatably supported by a framework comprising end plates 143 and 144 maintained in spaced relationship to each other by a rod 145 and a shaft 146, both freely engaged by said plates. The framework ror supporting the supply roll 142 is rotatably mounted between the plates 126 and 121 by means of two axially alined trunnion studs 141 in each of the plates 143 and 144 in cooperation with hubs 148 in said plates 126 and 121. The web of the supply r'oll 142 is wound around a metal tube or core 149 (Figs. 6 and 8), the inside circumference of one end of said core 149 fitting over a tenon of an axle 1'59 journaled in a bushing in the plate 144, and the inside circumference of the other end of said core 149 fitting over a similar tenon on a spring-pushed plunger rotatably mounted in a bushing in the plate 143, said plunger 15! being in axial alinement with said axle 150.

To mount the supply roll 142 in the framework 143 and 144, the righthand end of the core 149, as viewed-in Fig. 6, is slipped over the tenon of the spring-pushed plunger 15!, and said plunger is pushed to the righta'gainst the action of its spring until the lefthand end of the core may be slipped over the tenon on the axle 150. Each of the plates 125 and 121 (Figs. '1, 2, 6 and 9) has an identical cam'ming slot 152, which slots are engaged by similar rollers 153 on two similar levers 154, rotatably supported on opposite ends of the rod 145. 'Rearwardly extending arms of the levers 154 support a rod 155, said rod in turn being pivotally connected by two similar links 158 (see also Fig. 8) to receiving roll support arms 151 and 158 secured in fixed relationship to each other on the shaft 146.

By referring to Figs. 6 and 8 it will be seen that the web of the record material is unwound from the supply roll142 and threaded around the rods 145 and 155 and a rod 159 supported by the arms 1'51 and 158, thence onto a core 18!! for a record material receiving roll 18!. The core 168' i's-sim'ila-r'in every respect to'the core 149 for the supply roll, and is rotatably supported between the arms 151 and 158. r

The righthand end of the r'eceivingroll core 160 has therein two diametrically opposed clutch cuts adapted to engage two diametrically opposed tenons'on'a clutch 162 (Fig. 10) secured on the end of a plunger-like axle 153, rotatably supported in a bushing 184, secured in the arm 151. Also secured to the axle 183 is a knurled finger wheel 1 55 -'having thereina slot which engages an angular tongue 1B6 ona disk 161 secured to amend f'a hub'168 rotatably'mounted on the axle 16 3. The hub 168 has-secured-on the'otherend-thereof ating connection between these two parts.

a disk 189 and a receiving roll feed ratchet 118. A feed pawl 11! (Figs. 6, 10 and 11) pivoted on a stud 112 carried by a paper feed disk 113, free on the axle 183, is urged into engagement with the teeth of the ratchet by a spring 114. Likewise a ratchet retaining pawl 115, free on a stud 118 in the arm 151, is urged clockwise (Fig. 11) into engagement with the ratchet by a torsion spring 111. The disk 113 carries a stud pivotally supporting the lower end of a link 18! (Fig. 8), the upper end of which has a slot 182, which embraces the tenon of a stud 183 in a lever 184, free on the rod 145. The lever 184 has therein a hole which freely engages a tenon of a stud 185 secured in the lever 154 (Fig. 2.).

Inasmuch as the record material feeding means is operated in conjunction with the impression means, the manner in which the lever 154 operates the record material feeding mechanism, described above, will "be explained presently in connection with the description of said impression means.

The leithand end of the core 160 for the receiving roll 15! (Figs. 6, '7 and 8) is supported by a pilot washer 188 which engages the inside circumference of said core, said washer 186 being riveted to'the face of a spring-pushed plung er 181 having two diametrically opposed tenons adapted to engage two diametrically opposed clutch cuts in the lefthand end of the core 188. The tenons on the plunger 181 engage corresponding notches in the large diameter of a counterboring in a ratchet 189 to form an oper- The small diameter of the counterboring in the ratchet 189 rotatably mounts said ratchet on a fixed stud in the arm 158. A hub portion of the ratchet 189 has therein an annular groove which is engaged by "a retaining clip 198 (Fig. 7) secured to the arm 158 to hold the ratchet and connected parts against lateral displacement.

A ratchet operating pawl 19! (Fig. 9) has a slot 192 which fits loosely over the rod 159, and a torsion spring 193 urges said pawl 19% clockwise and rearw'ardly to normally maintain a tooth on the forward end thereof in contact with the teeth of the ratchet 189.

A disk 188, secured to the face of the ratchet 189, and the face of the finger wheel 155 (Figs.

7 and 10') form flanges for guiding the web of the record material around the core 199. Said disk 188 also serves to maintain the tooth of the pawl 19! in lateral alinement with said ratchet 189.

When the record material framework is in normal or reading position, as shown in Fig. 9, a rounded surface '194 on the pawl 19! is in operating relationship with a stud 195 in a lever 195 pivoted on the shaft 134. A boring in the lever 196 is freely engaged by a tenon of a stud 191 in the lower end of a link 198, the upper end of which link is pivotally connected to one arm of a lever 199, free on the shaft 2!2. A stud 898 in another arm of the lever 1'99 engages a slot in the stem of the record material space key !95, said key havin parallel slots therein which engage studs 88! and 892, secured to the left frame 80. A spring 803 urges the key !95 upwardly to normally maintain said key and connected parts in normal position, as shown in Fig. 9.

Depression of the key 95, when the record material framework is in normal position, as shown in Fig. 9, rocks the lever 199 clockwise, which through the link 198 rocks the lever 196 counterclockwise, causing 'the'stu d --H-l5 in -co- 7 operation with the surface 194 to shift the pawl 19! forwardly against the action of the spring 193 to rotate the ratchet 189 and the core 160 one tooth-space to line-space the record ma terial. A retaining pawl 804 free on a stud in the arm 158 is urged counter-clockwise by a torsion spring H9 to normally maintain the tooth of said pawl in engagement with the teeth of the ratchet 189 to prevent retrograde movement of the ratchet and the record material receiving roll 16! In applying the receiving roll core 160 the righthand end thereof, as viewed in Fig. 6, is slipped over a pilot washer 118 (Fig. secured to the face of the clutch 162, after which said clutch, the wheel 165 and the axle 763 are depressed against the action of their spring until the lefthand of the core 160 may be slipped over the'pilot washer 788 (Fig. '7). The washer 186, together with its plunger 181, is forced inwardly into engagement with the core I80 by a compressible spring in the counterboring in the ratchet 189. After the core 160 has thus been mounted in the printer framework, the knurled finger wheel 165 (Fig. 10) is rotated manually until the tenons of the clutch 162 and the plunger I81 drop into their corresponding clutch cuts in opposite ends of the core 160 to operatively connect said core to the automatic line-spacing mechanism and to the hand line-spacing mechanism.

- After the core 160 is thus mounted in the record material framework the web of the record material is unwound from the suppl roll [42 (Figs. 8 and 9) and threaded around the rods 145, 155 and 159, after which the end of the web is inserted in a slot in the core 180 and said core is revolved manually by the finger wheel 165 to start the record material winding around said core 160.

Impression mechanism The impression mechanism for printing in any of the columns of the multi-column record material shown in Fig. 5, comprises a platen which extends across the width of all printing columns of the record material, said platen being operated by a toggle arrangement which causes a squeeze type of impression to be effected rather than the conventional hammer--blow type of impression. The impression mechanism is supported by the framework 183 and 144 which moves the record material from reading position to printing position and return, and obviously said printing impression mechanism moves in unison with said framework. Therefore, when the machine is at rest, the impression platen is in a non-printing or substantially vertical position, as shown in Fig. 2, and during the machine operation said platen is moved from non-printing position to a printing position, as shown in Fig. 3, and the impression mechanism is simul-- taneously engaged with its operating mechanism, which upon oiperation causes the platen to squeeze the record material and the inking ribbon into contact with the type wheels 3E9 to record the data relating to the machine operation being performed.

The impression mechanism comprises righthand and lefthand arms 805 and 806 (Figs. 2, 3 and 6) similar in outline and each having similar slots 88? which engage the trunnions 14'! carried by each of the plates 143 and 144. Similar slots 808 in the lower ends of each of the

arms

805 and 806 and parallel to the slots 801, engage studs 8 809 carried by the plates 14'3'and 144, to slidably mount said

arms

805 and 806 in the record material framework. Each of the

arms

805 and 806 has on the upper end thereof inturned ears, which straddle similar ears on a U-shaped platen support bar 8| I, each set of ears being pivotally connected to each other by means of pins Bill which pass through borings therein. The channel formed in the U-shaped bar 8 (Figs. 2 and 6) supports a long resilient impression block 812, which is secured against displacement by three v screws threaded into the side of the channel bar,

said screws having pointed ends which penetrate the resilient platen block M2. The bottom of the platen block an rests on a long adjusting plate (not shown) supported in the channel of the bar 8| I, said plate being adjustable by means of screws threaded into the bottom of the frame, to in turn adjust the face of the platen block M2 in relation to the type wheels 3l9.

When the framework which supports the record material is rocked from reading position, as shown in Fig. 2, to printing position as shown in Fig. 3, the platen block 812 and its supporting framework also move in unison therewith and the line-spacing mechanism functions in a manner to be presently described to cause the record material to be automatically line-spaced prior to operation of the-impression mechanism.

Mechanism for rocking the rocking material framework from non-printing position to printing position and vice versa, comprises two identical studs 813 (Figs. 3 and 6) carried by the plates I43 and M4, said studs adapted to be engaged with notches in the upper ends of similar arms 8H3 when the printer framework 126 and 127 is properly mounted in the machine, as shown in Fig. 2. The lower ends of the arms 8 M are slotted to embrace a shaft 488 journaled in the frames 60 and ti, and each of said arms carries a stud 815, which extends through corresponding slots in each of two arms 818 secured to the shaft 488. A compressible spring 8H forms a resilient connection between the pair of arms 8M and MS and constantly urges said arms 814 upwardly to maintain the notches therein in engagement with the studs 813 (Figs. 2 and 3) regardless of the angular relationship of said studs to the shaft 488.

Secured to the shaft 488 (Fig. 3) is a crank 489 having pivoted thereto a pitman 490 carrying a roller 49! (Fig. 4) cooperating with a cam groove 492 in a cam 493, which is secured to the main drive shaft I30. This cam groove 492, through the pitman and crank, rocks the shaft 488 first counterclockwise and return.

Initial movement counterclockwise of the shaft 488 (Figs. Z'and 3) rocks the record material framework 743 and M4 from the position shown in Fig. 2 to the position shown in Fig. 3, to bodily move the record material supply roll M2, the receiving roll and the impression platen 8l2 from reading position to printing position. As the impression platen BIZ and its assembly move to printing position, the cam slots 152 (Figs. 2 and 3), in cooperation with the rollers 153, rock the levers Z54 clockwise in relation to the record material framework, which is also moving in a clockwise direction at this time. Clockwise movement of the levers 154 through the stud carried by the righthand lever 154 (Fig. 6) imparts a similar movement to the lever 184 (Fig. 8) which by means of the stud 183, in cooperation with the slot 182 shifts the link 'l8l forwardly to rock the disk 113 (see also Fig. 11) also in a clock-, wise direction. Clockwise movement of the disk (Figs.

9 [13 (Figs. 3 and 11) causes thefeed pawl I'll carried thereby, in cooperation with the teeth of the ratchet H0, torotate the core 160 (Fig. 10) and the record material receiving roll lfil the equivalent of one tooth space to line-space the record material prior to operation of the impression mechanism.

Clockwise movement of the levers I54 (Figs. 2 and 6) through the connections comprising the rod 155, the links 158, the arms 157 and 158, and the guide rod 159 slightly and momentarily collapses a portion of the record material guiding means to relieve the tension on the web of the record material while it is being line-spaced, to overcome the danger of tearing said web and to prevent unnecessary strain on the line-spacin mechanism. I

Clockwise movement of the record material framework M3 and 144 from reading position to printing position (Figs. 2, 3 and 6) engages two axia ly alined studs 8l8, carried by each of the impression arms 805 and 885, with notches in the upper ends of operating arms 828 and 82l secured to the shaft 134. An extension of the arm 820 has pivotally connected thereto the lower end of a toggle link 8 22, the upper end of which is pivotally connected by a stud 823- to a companion toggle link 824 pivotally mounted on a stationary stud 825 in the right side frame 8!. The stud 828 also pivotally supports the forward end of an operatin pitman 826, the rear end of which is bifurcated to straddle the shaft I38, said pitman carrying a roller 82'! which cooperates with a camming groove 828 in the righthand face of the cam em. with the roller 821, shifts the pitman 828 first forwardly (to the left as viewed in Fig. 3) and then back to normal position, after the type wheels 3|9 have been set by the differential mechanisms shown and described in. the parent application. Forward movement of the pitman 826, which occurs after the record material framework has been rocked to printing position, as shown in Fig. 3, expands or lengthens the toggle links 822 and 824 to rock the arm 820, the shaft 134, and the arm 82! clockwise. Clockwise movement of the arms 82!] and MI shifts the impression arms 885- and 886 rearwardly (to the rigl'i as viewed in Fig. 3) on their supporting studs i8! and 889 to cause the impression platen 852 to press the web of record material and an inkin ribbon 829 into contact with all of the type wheels to record the transaction on the web of record material as shown in Fig. 5.

After the impression has been made the pitman 825 is returned rearwardly (to the right as viewed in F g. 3) to shift the impression assembly to normal position, after which the shaft 488 is returned clockwise by the cam groove 492 (Fig. 4) to restore the record material framework 143 and M4 to reading position. When the framework is in reading position, the position of the record material carrying the recordings of the last transaction and several previous transactions is visible through an opening 830 (Fig. l) in a closure 83! hinged to the cabinet 69. The closure 831 encloses the. record material framework I26 and i2! and the opening 83f] is preferably covered with a transparent plastic material 832. An opening 833 (Fig. l) in the transparent material 832 exposes the lefthand edge of the record material so that various data may be autographed thereon opposite theprinted records of the transactions, if desired. A table. 834

The cam groove 828, in cooperation and, 8) supported by the rods 7,45" and atom-e4 1.55 of the record material framework, is located directly beneath the autographic opening 833 and provides a backing for the web of therecord material for the autographic entering of items thereon.

When the printer framework 126 and I21 is removed from the machine it is necessary to latch the record material framework M3 and 144 in reading position, as shown in- Figs. 1 and 6, so that the studs 8l3 will remain in alinement with the notches in. the upper ends of the arms 8M so that said. studs. will, reengage said notches when the record. material framework is again placed in the machine.v

This retaining of the rockable portion of the record material framework in reading position, as shown in Fig. 2,, is. effected by two identical latches 835 (Figs. 1 and 6). pivoted on studs 836 carried by the platesv 12% and 121. The latches 835 are urged clockwise by the springs 13! which are tensioned between. said latches. 835 and the latches 13.5,. which. latter latches secure the printer framework in operating, position, as previously explained. Each of the latches 835 has a stud 831, which studs extend, through corresponding clearance openings in the plates 126 and 12'! and cooperate with corresponding camming surfaces 838 on each of the plates 130 and HI to retain the hook-shaped upper ends of said latches 835 disenga ed from the rollers 158, which it will be remembered are carried by the levers 154, so that the record material framework 143 and 144 may be rocked to and from printing position during the machine operation.

When the printer framework, including the plates [26 and 121, and all the parts assembled therebetween, is. removed from the machine by manual release of the latches 135, in the manner previously explained, withdrawal of the studs 83'! from the surfaces 838 permits the springs 73! to rock the latches 835. clockwise, as viewed in Fig. 1, into engagement with the rollers 153 to secure the levers 154 and the rockable record material framework in reading position, as shown in Fig. 2 so that the studs 8| 3 will reengage the notches in the upper ends of the arms 814 when the printer framework is again placed in the machine.

As brought out in the general description of the impression mechanism, the printer framework is accessible through the closure 83I, which is hinged to the cabinet 69, and said closure is locked in closed position when the machine is being used as a cash register or when the machine is completely locked against operation,

and is unlocked when the machine is set for either read, reset or add operation, as has been fully explained in the parent application.

The closure 83l has two downward extensions 8 (one of which is shown in Fig. 1) each carrying a stud 842 adapted to be engaged by the hook-shaped endsof two identical latches 843 pivoted on studs 844 carried, respectively, by the frames 6! and 60, to normally look said closure 831 closed. Springs 845, tensioned between studs 845 in the latches 843, and stationary studs 84! in each of the frames 60 and BI, urge said latches 843 clockwise into engagement with the studs 842. An extending tip on each of the latches 843 cooperatesv with the studs 841 to limit the clockwise movement of the latches 843, under the influence of the springs 845, in relation to the studs 842, so that said studs may properly lay-pass the rounded noses of the. latches 843 when the closure 83.1 is being closed.

The studs 84B cooperate with upwardly extending fingers of two latch operating levers 848 pivoted on studs 849 in the frames BI and 68. Each of the downward extensions of the levers 848 has an arcuate surface 85!! adapted to cooperate with camming nodes 85! on two identical cams 852 secured on the shaft 459. When the machine is in the locked position so that it cannot be operated, and also when it is in the position to be operated as a cash register the cam 852 is inthe position shown in Fig. 1. However, when the machine is in a position to take a reading operation, a reset operation, or in a position to be operated as an adding machine, the shaft 459 is turned and the same nodes 85!, by their cooperation with the cam surfaces 858, rock the levers 848 clockwise, whereupon the latches 843 are rocked counter-clockwise and disengaged from the studs 842 to release the closure 83! so that it may be opened by the operator to gain access to the printin mechanism.

A tension device is provided for applying frictional drag to the record material supply roll T42 (Figs. 6 and 8), to insure that the web of the record material is held taut when the record material framework 143 and 144 is in either reading position or printing position, as shown, respectively, in Figs. 2 and 3.

The tension device includes a friction plate 853 (Figs. 6 and 8), having bent-over ears which freely engage the shaft 146, this plate having a slot 854 through which extends a pin 855, free in a hole in said shaft [46. A torsion spring 856 loosely coiled around the shaft 148 has one end thereof looped around an annular groove in one end of the pin 855 to retain said pin in place and the other end of said spring is looped around the downward edge of the plate.853. The spring 856 is tensioned to urge the plate 853 counter-clockwise, as viewed in Fig. 8, into frictional engagement with the circumference of the supply roll 142 to impart a braking effect to said supply roll to insure that the web of the record material is retained taut when the record material framework is in reading position or printing position.

The pin 855, in cooperation with the slot 854, prevents lateral displacement of the friction plate 853 on the shaft 146 and determines the extent of rotary movement of said plate under the influence of the spring 856.
