To ail whom it may concern."

Be it known that I, ADQLPHUS SYLvnsrnn DENNIS, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Adding-and Recording Machines; and I do deciare that the following is a full, clear, and exact description of the invention, which will, enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in adding and recording machines, and particularly to a machine on which i have two several applications in the United States Patent Ofiice for Letters Patent, one dated March 25, 1898, Serial No. 675,063, and the other having renewal date of March 31, 1898, Serial No. 67 6,006.

The present invention therefore consists of certain improvements on the constructions appearing in said application, all substantially as shown and described, and particularly pointed out in the claims.

. In the accompanying drawings, Figure 1. is a side elevation of the complete machine. Fig. 2 is a plan view of the machine. Fig. 3 lincA A, Figs. 2 and 6. Fig. 4 is a longitudinal sectional elevation on line B B, Figs. 2 and 6. Fig. 5 is a central longitudinal sectional elevation on line C (J, Figs. 2 and 6. Fig. 6 is a plan view of the machine on section-line D D, Fig. 4. Fig. 7 is a plan view looking down from line E E, Figs. Land 5. Fig. 8 is a rear elevation of the machine looking to the left fromline G G, Fig. 4., Fig. 9 is a cross-section on line F F, Fig. 4, looking to the right. Fig. 10 is a front elevation, partly sectional, of the carriage and the pivoted columndetormining levers therein. Fig. 11 is a cross-sectionof the adding-wheels proper, the totalizing-wheels and associated parts on a line corresponding to H H, Fig. 12. Fig. 12 is a cross-section of three several adding-wheels, showing their bearings, as hereinafter more fully described. Fig. 13 is a cross-section on line 1 1, Fig. 11, showing the totalizing-wheels on their shaft. Fig. 14 is a perspective detail of a single totaiizingwvheel out of the group in Fig. 1 3. Fig. 15, Sheet t, is an elevation of the type-bar for printing the items. Fig. 16 is a cross-sectional view of the machine on a line corresponding to L L,Fig. 2, but omitting all the mechanism, except that shown for automatically shifting and feeding the ribbon. Fig. 17 is a detail sectional view, enlarged, of one of the ribbon-wheels, as hereinafter more fully described. Fig. 18 is a sectional elevation of part of the mechanism shown in Fig. 16 on line J J at the left. Fig. 19 is an elevation on line K K, Fig. 16.

In the views thus shown 2 represents the frame of the machine, which carries all the other parts directly or indirectly, whether stationary or operative. The keys are represented by 3, of which there'are ten in this machine, running from O'to 9, inclusive,

and in addition thereis a space-key 4: to correct errors in the coiurnn work, as heremafter described. The nine several keys are employed to write the items, whatever their size,

but have nothing to do with the totalizing mechanism, which is a separate line, as will be seen farther along.

The carriage 5 rests horizontally across the top central portion of the machine, as seen in plan, Fig. 6, and in elevation, Fig. 5, and carries a number of parts, as will appearit runs on ball-bearings on the channeled crossraiis'ti of the main frame and is under constant spring tension through the flat springcoil 7, Fig. 7, having one end fastened to its inclosing case 8 and the other to shaft 9. A,v

drum 10,.rigid on this shaftI and acorrespond-- ing drum 11 on the opposite side of the machine, Fig. 9, are connected by endless metal tape 12, secured to the carriage 5 at one point, so that every time a key-lever is depressed to print a character the carriage is fed forward one step after the manner of a typewriter.

On the rear end of shaft 9 is a segmental ratchet 13, adapted to be engaged by two escapement-pawls 14 and 15, successively, Fig. 8. These pawls are arranged side by side on an upright rocking postl6, which has a head '1? on which pawi 15 in rigid and pawl la is pivoted. Normally pawl it engages ratchet 13, and when a key is depressed post in is retated and pawl 14- carried inward out of on gagement, while at the same time pawl .15 takes its place before permitting movement of the ratchet 13 and holding shaft 9 still. l deantime pawl 14 has been drawn down by its link connection to engage the next lower tooth, as will soon appear.

All the key-levers have like operations, and when any one is depressed it strikes the cross-- frame iii beneath, Fin". Said frame is pivoted at both sides on cross-shaft 19, on which the keys are independently pivoted. Frame 18 has an arm 20, centrally through which the rear vertical pawl-carrying post 16 is rotated by means of rod 21, having" an i..-shaped head 22, and the arm 23 on post 16 havingin this instance a set-screw 2 engaged by head 22 when it is forced inward by arm 20. This causes post 16 to rotate just enough to exchange pawls in engagement with ratchet 125, as above described, and this occurs every time a key-lever is depressed. 'ihe further action of pawl 14 is dependent on the movement of the printing hammer supported on arm 26, carried by shaft 27, Figs. 5 and s. The blow of this hammer to make an imprint is dependent on spring-pressed bolt 30, which rests against short arm 31, rigid with shaft 27, said bolt being; confined to opcrate in the casing" 32, containing; spring 33, hearing against the head of said bolt. Another short arm 34:, rigid with shaft 27, engages the short portion of L-shaped head 22, in which is a slot 35, adapted to receive the downwardlycurved end'of said arm 3 1 when said head is carried rearward through the action of rod 21, and shaft 27 is rotated as the hammer 25 delivers its stroke. 'llhen as the kcylever which has caused this action rises the rod 21 is carried back by the action of its spring 36., the short arm 3% is raised out oi its slot to position, as in Fig. 5, by the pull from spring 7 on shaft 9 and pawl 14 and its link -11, bolt is forced back under this pull, and hammer 25 assumes normal retired place.

Now reviewing the operation of pawl 1 1, Fig. 8, the said pawl is pivoted in head 17 and is subject to opposite movements. Thus a bolt 4:0, supported in arms on the post 16, serves to hold the said pawl up in normal position to engage the teeth on ratchet 1'3; but being spring-pressed said pawl can be pressed back by the teeth on the ratchet to allow for the rotation of said ratchet and its shaft 9 when the carriage is set to starting position. it also has a link 11, connecting with arm 4:). on shaft 27, so that when said .shaft is rotated for the actuation of the hammer it will pull down the pawl 14: for enough to engage in over the next pawl below, as pawl 15 is released by swinging backward to rest instantiy on releaseolf the key-lever. 'ihen manta as pawl 14 rises to normal position it allows, rotation enough of segment 13t0 make a step of feed for the carriage to print in the next column. A bow-spring 14" (shown in Figs. 5, 7, and 51) returns post 16 to normal position, and then pawl 14 is engaged by a lower tooth on ratchet 13 and is carried up to the limit of its movement by the rotation of the ratchet under its own spring-pmver. This spaces the carriage.

i'iometimos it is desirable to do spacing without opcratin a key-lever, as when an error in setting; the carriage occurs. For this purpose ll have the lever 41 apart from the key-levers proper and which is rigid with shaft 19 thereon. This particular lever has an arm 44, rigid with itself or with shaft 19, adapted to engage push-rod 45, Fig. 5, and through arm 23 on rotatable post 13 actuates pawls 14 and 15, thus affording an independent way for feeding the carriage 5. in this operation the moment pawl 14 is disengaged from segment 11-5 the bolt 30 is free to act and throw the ham mer-arm 26 forward; but the hammer is deterred from making a full stroke by the I.- shupcd head 22, which now serves as a stop by reason of arm 34 striking the top of said head instead of entering slot 35; but this limitod action of bolt 30 is sufficient to rock shaft 27 and pull pawl 1 1 down by means of link 41 and arm 12, and thus pick upthe next lower tooth when post 16 is rotated to its normal position by the pressure of bow-spring 14'.

(in the rear of the carriage 5 are feed-rolls at! and 18, between which the sheet of paper printed upon is placed, afecd-spoutdi) for the sheet being shown in this machine. The paper is fed upward by these oils with the inkribbon 51 between it and the type-bar 52. Said bar, Fig. 15, Sheet 4, is adapted to slide back and forth in a slot in the top cross-piece 53 of the main frame to bring any called-for figure into printing position. It bearsligurea or characters corrcspomling to those on the keyboard, so that the depression of any given key brings the corresponding character on this bar before hammer 25 for impression.

A line of separate mechanism connects said bar with the key-levers, Figs. 5 and 9. Each i e \,'-lcver 3 has an arm 5 1, projected beyond its pivot on shaft 19, engagim, beneath plate 55, fixed on shaft 56. The said arms are graduated in length according to the denomination or value of the key-lever in the series, the lever having the highest numeral or character requiring the farthest throw as this machine is organized. The rotation of shaft 56 through wing 55 moves shaft 56 and the miter-gear 57 thereon, Fig.1), which meshes with segment 58 on upiight shaft 60. The said shaft 61) has an arm 61 at its upper end, Fig. A, connected by link 62 with typo-bar 52. This produces exact correspondence and selection between the characters on said bar, which are from U to 9 in this instance, and

the key-levers of the same value, and the selections are unerring when the right lever has been touched. Normally the cipher is opposite hammer 25, in which case the bar 52 does not move to make an impression. Spring 64, connected with an arm on upright shaft 60, restores said shaft to'initial position after each action.

A separate back-stop is provided to limit the throw of arm 61, according to the character selected on the type-bar, said stops consisting of small vertically-movable bolts 66, .each adapted'to shoot up in its own' hole 67, Figs. 2 and 6, when called. These bolts 66 extend from under the bottom of the machine, Fig. 8, to the top and are operated by the keylevers through diagonally-arranged levers 68, pivoted between their ends on the under side of the machine and engaged by rods 70 at each to its own key-lever their frdnt ends. These rods are attached and have springs about them to restore the key-levers to work ing position after each depression. The lower ends of said rods simply bear on levers 68, but might be pivoted thereto, and so it occurs when any key-lever is depressed it throws up its corresponding back-stop bolt for the arm This makes positive what might otherwise be an uncertain stop for said bar. Eight of these stops 66 are here shown, one of which, the last one at the left being a fixed stop. No stop is shown for'the first movement of type-bar 52,

. because the momentum of the same under the 1 machine and for printing 4p in the item to be printed.

"used to engage each its own slight impulse of lever 1 will not carry said bar beyond alining position with hammer- 25 to any perceptible degree.

; .The carriage 5 normally is at the left of the is moved toward the right as many points as there are figures Thus if the sum or item he, say, 365 the carriage is carried over to point the first figure in the hundredscolumn, the second in tens-column, and the third in units, and. the vertical thumb-levers 72, Figs. 5 and 10, particularly serve to fix the starting place for any given item, large or small. These levers are pivoted in a box- .ing 73 on the front of the carriage and have substantially right-angled projections or fingers 74 at their bottom adapted when said levers are particular stop 75 on the frame below, thus preventing the vmoyingof the carriage to the right farther than the right stop will allow. Thus if the third lever from the right he engaged by the 72- had been operated, sa

thumb to move the carriage to startin '-place in hundreds-columnit would engage, say,

.the third lug or stop 75 from the right and stopping the carriage there make that the starting-point for printing that item, tens being next and units last. If the wrong lever in. the temthousand column, the spacinglever gz can bemneratedfto bring the machine to set the machine to the right position, and then operations begin through the key-levers. The In gs or stops 75 are staggered, and the points 74 of the levers are arranged in respect thereto so that each will engage only its own stop and none other, and all the levers are arranged to work with the spring-pressed bar 76, or they may have retracting-springs of their own, or both, as preferred, to restore them to normal position. Hence in printing an item the first thing to do is to bring the carriage to the right place according to the column in which the fix st figure is to be printed. Then printing goes forward through the key-levers, and this operation is repeated for each successive item indefinitely.

The hammer-arm 26, so called, Fig. 8, is really a heavy wire bow having its two extremities fixed on the shaft 27 at the-sides and bottom of the machine, and the hammer is adjustably secured thereon.

The foregoing mechanism mainly has to do 4 with the printing of items, and the total or sum of the items need not be struck off if not wanted; but it has been faithfully added up as each figure has been recorded and now nothing remains to be done but to strike off the total in a single line and at a single stroke by or through the totalizing-hammer. In this carrying forward ofthe work for totaliz- 95 ing the items I employaset of adding-wheels 77 and a set of total or recording wheels 78, Figs. 5 and 11, and with these the initial operating-wheel 80, through which each addingwheel isv reached by sliding wheel in beneath it. There are as many or more addingewheels as key-levers and a certain recording-wheel geared with each adding-wheel, so that each lever not only works a line of mechanism to print the items, but also to add the items as they are printed by carrying their sum forward with the adding and total wheels.

The wheels 77 and 78 are supported within the walls of what is termed the stationary head 81, Figs. 2 and 9, while wheel 80 is adapted to slide on shaft 82. movement it is controlled by a carrier-arm 83, which is fixed at its lower end to a longitudinally-sliding shaft or rod 84, Figs. 7 and 9, and this rod is connected by rigid arm with the endless belt 12, attached at its top to the carriage 5. The carrier-arm 83 engages in the hub of wheel 80, so as to give a positive movement to the wheel and hold .it where adjusted, but leaving the wheel free to turn. Thus it occurs that wheel 80 is caused to respond to every movement of carriage 5, and by reason of this connection of arm 83 with belt 12 below the drums 10 and 11- the wheel 80 is always moved in the direction opposite to the carriage. Hence if the earriage be moved by hand to theright the said wheel travels a like distance tothe left, and the parts are so arranged relatively that if the carriage be set to start printing in any In this sliding given column the said wheel will come to the same column. This also places the said wheel in harmony with, the key-levers, so that it will carry into the totals the sum called for by said levers. If the figure be, say, 5, the wheel will rotate the adding-wheel 7 7 with which it is engaged to carry up five points, and the same with any one of theseveral addingwheels to which for the time it may be moved through the keydevers and carriage.

The shaft 82, carrying wheel 80, is rotated from shaft 56, Fig. 5, by segment 86 thereon engaging segment-gear87 on shaft 82. This gear rotates loosely and carries a pawl 88, which engages ratchet-wheel 89., fixed on said shaft. Hence this ratchet alwaysholds every point moved up through segment 87.

Now referring again to the adding-wheels 77, Fig. 12, it will be noticed that they are each mounted to rotate on a hub 90, rigid on shaft 91, and each hub has race and antifriction-balls about its periphery to afford an easy action for said wheels. The hubs 91) are all engaged also with the parallel rods 92, and each adding-wheel has two cams 93 at its side, with ten points corresponding to ten in addition between the shoulder of each cam, and a lever 94 rides on each set of cams through a roller bearingthereon. Adog95 on each lever 94 engages with ratchet-teeth 96 on the side of the wheel 77 in the wheel next higher numerically, so that when pivoted lever 94 through its roller jumps or drops off the shoulder of a cam 93 the spring-pressed rod 97 pushes dog 95 forward and gives a single-point rotation to the next higher adding-wheel, thus carrying a number into said wheel. The same opera tion extends through all said wheels, and in this way the items are, first added upinto theadding-wheels themselves. A spring-pressed pawl 98 engages ratchet 96 at the side of each wheel to prevent backward rotation.

in order that each higher wheel be unlocked from arm 100 when cam 93 on the lower adding-wheel shall have reached the point where the carrying forward of a point is necessary, as in recording'when one is added to nine, 1 provide each lever 94 with a side projection or pin, which in'this instance comprises the extension of the pivot-pin which attaches rod 97 to lever 94. This extension of said pin bears against the vertical arm of dog 100 at a point above its pivot, and whenever cam 93 presses lever 94 back said extension releases the next higher wheel by pressing its locking-dog 101) out of engagement with the teeth on said wheel. The series of higher wheels are all thus released to admit of the carrying forward of theamounts added to the lower wheels.

Each adding-wheel has also a catch or dog 100, Fig. 11, which is normally engaged with the teeth thereof to keep the wheel from rotating except when required, and the said catch is substantially L-shaped, pivoted at its angle remote and having its short arm arranged to be engaged and depressed by roller 101 on the top of wheel-carrier 83, so that when said wheel 80 is slid on its shaft into engagement of any one of the wheels 77 the roller 101 at the same time unlocks the catch 100. This liberates that particular adding-wheel for rotation, and the catch drops back as soon as the carrier is moved on. all the catches 100 at the same time, so as to enable all the adding-wheels to be alike turned to starting-point after a given task is com plated, 1 provide a rotatable cam-shaft 104, Figs. 5 and '11, adapted to bear in the short arms of catches 109 and throw them all out at once. The said shaft is turned by means of crank-lever 105, Fig. 1, gearlbli on shaft 107, and gear 108 on shaft 1.04. A pawl 110 on the inside of gear 198, Fig. 3, engages it with shaft 104, and thus it is rotated; butsaid pawl can be disengaged by depressible belt 119. This enables a total to be struck off at any time without wiping out the additions then in the adding-Wheels, and frequently it is desir" able that this should be done. Then the gear 108 will run idle, and the other chain of gears going to the paper roll for printing the total and marked 113, 1 i l, 115, 116, and 117, succes-r sively, will operate alone, as hereinafter seen.

Referring now to Fig. l, segment 118 on shaft 104 meshes with gear 12-1) on addingwheel shaft 91. way round, which is all it requires to bring the raiding-wheels back to zero, as a half-rotation of them sullices in any case, havingtwo stopping-points each at their camsl1oulders. This also gives time for the total or aggregate to be struck off through the rotation of crank before the adding wheels are set back. in this rotation of the wheels 77 to more they travel in their usual direction and are each engaged by its own pawl 121 at its side and fixed on one of the rods 92, Fig. 12.

The totalizing-lutmurer 123 is fixed on a vibrating frame 122, which hasa lateral sliding movement suili cient to carry the hammer over opposite the Vital-wheels to strike oil any given total more or less; but it never moves farther over than to take off the total then made. This prevents printing a series of naughts beyond the figures of the total, as would occur if the entire nine total-wheels were always covered. 1 limit this action of the hammer to the wheels used by means of a splined rod 1524, Figs. 5 and 11, adapted to run in a transverse slot across the edge of all the wheels 7 8 and which is open across all of them alike when said wheels are brought back to starting-point.

When this occurs, their ciphers are all alikeexposed at the front. Of course all the wheels not used to print a total remain that way. Hence the spline-rod 124 can run into all the unused ones; but this is its limit, and this ,1 utilize to determine the movement of the hammer 123 laterally.

When it is desired to disengage (-lear 118 has teeth only halb Fig. 3 ready to'be moved to action.

resets g t 1525, her" in -Fig. 1 1 show an inc ing an arm 126 its bot god with s projection on the slid rec 12?, carrying hammer-ironic 1522. At its tor; is an arm 128. connected with one end or the long spring pressed spline-rod 11 short arm 136 on shaft 1125, Figs 3 end 6 runs in engagement by roller with cem 131 on shaft 10? in i, 106., and by thus rotating shaft 25 i get I! necessary sweep to both arms 126 end 1528; and they move together the some distance.

Hemmer 123 :ind splined rod 124;; have s. simultaneous lsiterel movement wl ch dependent upon the coiled spring nponfsplined red 12 1 and. com 131. The spring normally holds the roller of arm ldongeinst the high point of the cam which keeps both hemmer 123 end spline'd rod 124: to the extreme left until the com is rotated. As the roller rides 0d the shoulder of the com the presses splined rod 124 to the right, which cerries the spline or key on the rod along the transverse slot heretofore described until the end of the spline strikes against the face of on adding Wheel whicn has been rotated and whose slot in the edge thereof has been moved out of line Hammer 123 moves leterelly'the some distance es splined rod 1%, end when said rod is stopped so is the hemrncr which. then covers only the adding-wheels upon which the total is recorded.

The hemmer 123 is caused to strike by shouldered com 133 on short shei't 13 5., carrying gear 113, arm 135, lying against said cam, shaft 136, carrying seid arm, and another arm 137., rigid with seid shaft, Fig. 1, and bearing .et its extremity against it boil 138 along the bottom of hammer-shaft 127. A heavy spring M0 presses against arm 13?, end the moment arm 135 drops 0d the shoulderof cam 130 this spring gives en efiective blow to hammer 123. Normally the seid'sev erel parts are in about the relation shown in A. depressible stop 1 12 fixes the stopping-point of crank-lever 105, through which these settle-- tions are made.

In Fig. 4 it will be seen that there are four pins 1 15 in pairs above end below the shaft 91., on which rests yielding spriiig erin 1 16, supported on the frame.

The totalizing or total-recording wheels 78 are loosely supported on e. common shaft and have ten characters each on their periphery equally spaced apart and corresponding teeth at their sides in mesh with the opposite odd: ing-wheeL The two sets of wheels are so arranged that every unit added into one is cerried forward into the other set, and the units, tens, hundreds see, are tar-zen core of in the total-wheels through rotations from the adding-wheels.

Means for actuating the feed-rolls t7 and 18 to set the paper at the proper elevation for each new line of figures to be printed consists .72 is ectneted.

/Vhcn the total is to be printed, -the feedrolls are actuated to rotate first in one direction to carry the paper down slightly, so that the totel will be printed in close relation to V the lost figureprinted, and second in the 011- posite direction to feed the paper upward efthe total has been printed to bring the me in plain view. at the top of the machine. This reverse motion is etteined through gears 113 to 11?, Figs. 1 and 3, gear 117 having a. long list-sided shaft which extends into feedroll shaft 148 to rotate rolls 4:? end slidingly engaged therewith to allow for the side move- 5 merit of the carriage. Gem's and 1-16 are in constant mesh with gear 117, and gesrl'l? elwsys in mesh with 106 on shrift 10?.

This stop mechanism is governed by a depending erm 162 on each key-lever en- 1 5 gegine a separate sliding rod 163 for each key, the rods being mounted in a frame 16 1 and having their opposite ends bearing against a pivoted plate 165. The top or free end of this plate has a sliding engagement within the bi- I20 forested arm of member 160, and whenever a key-lever 3 is actuated this plate 165 and stop 161 are also thrown into action by its respective rod 163; but the lever-arms 162 are set back slightly from the ends of rods 163, so that the 5 stop action is not brought into play until the adding and totalizing Wheels are first actuated, the second movement being timed for each of the keys snd their corresponding adding and totalizing wheels. 3

In order to obtain a clear and neat print at all times, 1 provide automatic means actuated by the movement of carriage 5 to constantly change the inking-surface of the ribbons 51 and170 and which causes the ribbons to feed slowly across the face oi the type-bar and type-wheels first in one direction and then in the opposite direction. Diii'erent shades or colors of ribbons are used, so that the items will be printed in one shade and the totals in another. These ribbons are wound ove spools 171, supported at the top and at each side of the frame 2, and pass from one spool to the other across the face of the type-bar and the type-wheels. 'Spools 171 are splined to vertical shafts 17 2 and caused vto alternately rotate in opposite directions when the ribbon is unwound entirely upon either of the spoolsr The vertical shafts 172 are slidingly mounted in arms on the frame 2 and have each a pin 173. adapted to engage a notched sleeve or collar 174, rotatably held in arm 175. This collar has a beveled gear 176 meshing with beveled gear 177. on cross-shaft 178. This shaft has a larger beveled gear 17 9 meshing with a gear 180, that is actuated through suitable gearing from spring-tension carriageopcrating shaft 9. Only one of the pins 173 is in engagement with a notched sleeve 174; at a time, and it is byreleasing and relocking these sleeves for each shaft 175?, that the said shafts are made to reverse' This is accomplished by means of the cross-rod 190., having the arms extending at opposite sides of the center at the ends and which engage the lower extremities of the vertical shafts 172 and be in]; in constant touch therewith. "On each shaft 172 are the gears 181, which mesh and have a sliding movement with gears 182 on the vertical screw-threaded shaft 183, mounted to. rotate in the frame at the side oi shait 172. A nut 184 on each shaft 17 2 has an extension which bears at certain intervals upon a spring 185, resting on a collar on said shafts. As shaft 17 22 rotates screw-tlueaded shaft 183 is also rotated and causes the nut to travel up or'down. As shown. the hut 18st at the right side of the machine is caused to travel down while the nut at the left goes up ward. The nut coming down engages spring; 185 and gradually compresses it, and it nothing' were to hold the shaft 17 2- in raised position pin 173 would drop into notched sleeve 175. This is permitted only when the ribbon on spool 171 at that end of the machine has been unwound and reached the end of its travel where fastened to the said spool. Each spool is provided with apivoted catch 187 having: a spring to press the free and outward, and also having a separate spring-pressed bolt 18h, which rests in the groove 189 near the top of shaft l72-that is to say, in that particular shaft which is tci'nporarily to beheld in raised position. The ribbon 170 bears against the free end of catch 187 and normally holds the same bach reacts and its bolt its. in locking engagement until the ribbon has entirely unwouml itself. This trees the catch, and its spring; forces it outward and withdraws the bolt from groove 189, allowing spring 185 to press shaft 172 down and lock pin 173 with sleeve 175. The lower extremity of shaft 17 2 lorcesdown the arm on cross-rod 190 and rocks this suilicicntly to cause .the arm at the other end to force shaft 17 2 at the left up, thus freeing its locking-pin connection with sleeve 17 5 at that side. As this shaft 172 is raised it is held in that position by bolt 188, entering shaft-groove 189, until the ribbon at that side is unwound these movements being automatically controlled at each side of the machine and the ribbons being fed in reverse direction at long intervals.

Now as an example in operation suppose that two items---- 852 i and 598--'are to be printed and added together, in which the total is 14:22. Having" set the machine to start printing in the third. or hundreds column and striking the hey-lever 8 for the lirst item, an imprint oi said figure will be taken from the type-bar in the item-line, and the hundreds-adding wheel will be turned up eight points with a corresponding movement of the opposite totaliain ewheel. Then having printed the figures it and 4: of this item in their columns there will be 824; represented in both the adding-Wheels and the totalwheels-t, which latter are an expression of the value in the adding-wheels and also an imprint of 89st on the paper from the typebar. Then after recording the next item, 598, in like manner and really having M22 in these wheels the hundreds-wheel necessarily is carried three points past the ten therein, and one point is turned forward in the thousands-wheel at its left. The fur ther addition increases the totals in all three wheel-columns and carries forward another hundred in the hundredscolumn. it has also occurred in the units'colnmn that one ton has been taken out and carried forward in the tens-column, leaving two therein, while one tea has been taken out of the tcnacolumn and carried forward into the hundreds, leaving two therein. New referring to the totalizing-- wheels it will be found that they have been rotated to correspond exactly to the results in the addingevhcels and that when the total is struch therefrom it will show up w 1422.,

' the sum of both items,

The recording-wheels are so called by ititt' son of their serving to give the record in print, and their mines are always the same as those oi the addhnrerheels which they represent.
