1'0 all whom it may concern:

Be it known that I, EDWARD J. Von Pam a citizen of the United States, and resident of Dayton, in the county of Montgomery,

5 State of Ohio, have-invented certain new and useful Improvements in Cash Registers,

of which I declare the following to be a full, clear, and exact description.

This invention relates to improvements in 1 cash registers and has more particular relation to the t of cash registers shown and described in tters Patent of the United States issued to Thomas Carney May 23, 1893, and numbered 497,860, and also in the United States Letters Patent to Joseph P. Cleal No. 718,565, issued January 13, 1903. The general operation 31nd construction of the machine shown inthe present application is substantially like that shown in the Carney and Cleal patents. F

The purpose of the resent machine is to enable a proprietor o a store selling taxable goods to keep an account of the sale of all goods upon which there-is placed a, Government tax and also to keep account of the proper tax which is collectable by the revenue department of the Government on the sale of such goods. In the accomplishment of this object. the machine isarrangedto enable the proprietor T to register simultaneously both the amount of a purchaseand the amount 'of proper tax to be applied thereto. F

It is a further object 'of the machine to provide not only for the registration of'the amount of the purchase and theamount-of the tax assessableon the purchase, but also to make a printed record of both the amount of the tax and the amount ofthe purchase 1 and to indicate both the said amounts.

As it uently occurs that a sale of oods on which no tax is assessed is to be andled by the same cash register as that which handles the sales of taxable goods the machine is so arranged as to enable the'proprietor to make a record oi the sale of nontaxable goods and also to make a record of the fact that no tax has beenfiregistered in connection with that sale. a

As it is desired in order to'compel a clerk or operator offthe cash register tomake the proper records in the machine the machine away of the mechanism for is so arranged as to compel the clerk or operator to make a record not only of-the amount of the purchase but also the amount of the assessable tax, or in case the sale involves (goods against which no. tax is to ,be assesse to make a proper record of the fact as well, so that the printed records of the machine andalso the public indication will clearly show the-amount of the urchase, the assessable tax, or in lieu ofthe latter, some character or'symbol to indicate that no tax is assessable. b

With these and incidental objects in view the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are setforth in appended claims and a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of this specification.

Of, said drawings:

Figs. 1 and 1 taken together constitute atop plan view of the machine with the cabinet and certain parts omitted for the sake of clearness.

is o 1 e machine in general comprises banks grinting' mechanism shown in.

parts being rotating the of depressible keys',-;certain banks represent-i" resenting the amount of the purchase. e operation of the machine comprises. an initial depression of one ofthe tax keys which will serve tounlock the keys.representing the amount of purchase thereby permitting "the operation of the purchase keys.

The operation of the purchase keys will through mechanism common to the tax keys and purchase keys, efiect a complete operation of not only the purchase keys but those of the tax keys which have been initially operated. I I a 7 Separate totalizersare rovided for the tax keys and the purchase eys whereby the amount of the tax and the amount of the purchase will be registered separately on their pro r totali zers. I

When it is desiredeto operate a purchase key to record a purchase of goods which is non-taxable, a no tax key is provided which serves to disable the locking mechanism which normally prevents the operation of the purchase keys 1; ereby permittin the operation of a purchase ke This, w result in registering the pure ase on the purchase totalizer while no entry is made on the tax totalizer.

The usual indicators for this type of machine are provided for all of the ke s of the register so as to indicate to the pub ie which of the keys bothof the tax and purchase groupshave been operated. I

Simultaneously with the registration of the amounts on their proper totalizers a printing of these amounts is efiected by the .printing mechanism, the a ount of tax and the amount of the pure e being printed in separate columns on said strip.

Described in detail the machine comprises a series of amount or urchase keys 10, a

series of tax keys 11, a no tax key 12 and a no sale key 13. All'of the keys 10, 11, 12 and 13 are pivotally mounted upon a trans.- verse shaft 14 (Figs. 2 and 5) Supported in side frames 15 and 16. Common to all of the kiiys 10, 11, 12 and 13 is a key eou ler 17 of a orm well known in the art an described in the aforesaid Carney and Cleal patents. The key coupler 17. is pivoted at .18 at each end in the side frames 15 and 16, and normally rests on the rear ends of the urchasekeys 10 and no sale key 13. Eac of the'purchase ke 10 and the no sale key 13 is provid with a notch 19 2) which is adapted'to cooperate with (Fig.1 'the 'p 20 formed onthe rear edge of the key coupler 17 when keg 1 3 is depremed.

uitably mounted in the side frames 15 and 16 is a transverse rotary shaft 21 which is adapted given a complete rotation upon each reciprocation of the key coupler 1 by the mechanism shown in detail-in Fig. 6. By referrring to said figure it will be any of the keys 10 or fully ,esa

noted that at its right hand end the coupler 17 is provided with a stud 22 which projects into an elongated slot 49 formed in the vertically reciprocable double rack 23. At its lower end the double rack 23 is. provided with an open slot 24 which straddles a stud 25 carried by the right hand side frame 16. At its upper end the rack 23 is also slotted and the inside walls of the slot arefurnished with oppositely faced rack teeth 26 which cooperate with a pinion 27 fast on the rotary shaft.21. At the end of the down stroke of the key 10, lug 223 (Fig. 6) is at the top. of

nism shown in the aforesaid Carney and Cleal patents and also in the patent to Cleal, No: 773.060, issuedOctober 25, 1904, and is for the accomplishment of the same purpose, that isthe gi'vingof a complete rotation of the shaft 21 at each reciprocation of the key coupler 17 the rotation bein in the direction of the arrow shown infi 'gs. 2 and 6.

In order to prevent a retrograde movement of the shaft 21 a ratchet or full stroke disk 28 is made fast to the right hand end of the shaft 21 and cooperates with a pivoted fullstroke pawl or lever-29 pivoted at 30 to the frame of the machine and held in engagement with the ratchet 28 by a spring 31 seated in the lug 32011 the right hand side frame.

It will thus be seen upon each complete depressionof a purchasekey 10 or no sale key 13 the keycoupler 17 will be reciprocated and through the connections shown in Fig. 6 and above described, a complete single rotation will be 'ven to the shaft 21. The function of the fly in the art is to lar key and the twenty oeiit key and then coupler 17 as well known rmit the starting of an operation of two eys, for example, the dolcomplete the operation by pressing either one of the two keys. ,By reason of the engagement of the lip 20 of,the key coupler' 'with the notches "19 in the key 10 both the dollar key and the twenty-cent key will be' fully operated by the complete depression of either one of the two. 7 y

i Tam keys.

The tax keys 11 and the no tax ke 12 are of a. different construction than the' ys 10 and '13. The construction of these keys substantially that shown in United States Letters Patent to E. J. Hall 1%.

875,661 dated December 31,1907 and w s. Dot No. 823,516, issued June 19. 1906.

t e keys lland 12 are of the construction shown ,in Figure 5. It will be noted that these keys 11 and 12 are cut away as at 33 so that-when the key coupler 17 is resting on the keys 10 and 13, as shown in Fig. 2, 1t

of the ke s 11 and 12 is for the purpose of unlatc ing the purchase keys and no sale key to permit an operation of the latter keys in a manner to be hereinafter described.

Each of the keys 11 and 12 has pivotally mounted near its rear end a pair of pawls 34 and 35. This construction is substantially like the constructions shown in the Hall and Doty patents just above referred to and is for the purpose of holding the keys 11 and 12 in the partially depressed position. The normal positions of the pawls 34 and 35 are substantially that shown in Fig. "5 wherein it will be seen that .the pawl 34 whichis pivoted at 36 is normally held against a 'stationary frame portion 37 by a sp 38 interposed between the lower end of the pawl and a stud 39 carried by each of the keys. At its upper end the pawl -34 is provided with a hook and 40 adapted to cooperate with a locking oint 41 of the pawl 35 as will be hereina ter described. Whenv any one of the keys 11 and 12 is depressed the rear end of the key will be elevated until the lower end of the pawl 34 passes clear of the stationary frame portion 37 when; under the action of spring 38, the lower end of said pawl will move rearwardly above the frame portion 37. 'When the pressure on the forward end of the key 30 is removed the pawl 34 engaging with the frame portion 37 will hold the rear'end of the key elevated. As the rear end'of the depressed key moves upward the face 42 of the pawl 35 will strike the under side of the lip 20 of the key-coupler 17 and during the continued operation ing the the paw 34 and" bringing a face 44 across of the keys 11 or 12 the pawl 35 will be rocked clockwise around its pivot 43 carryint 41 away from the hook 40 of the notch 19 in the depressed key. This initial depression of any of the v.keys 11 or 12 will,'w en the rear end of the key is elevated, cause the point 45 which is at the outer end'of the notch 19 to cross the are of movement of the rear edge of the lip 20 of the'key coupler 17. Consequently when' the key coupler 17 is rocked clockwise about its pivot 18 by the depression of a key 10 or 13 the lip 20 will engage the point 45 at the outer end of the notch '19 of the key 11 and engage the face 44 of the awl 35.

'During the. continued operation 0 the key will enter the notch 19 of the key 11 or 12 i coupler 17 the awl 35 willbe rocked coun= tar-clockwise a out its pivot 43, (Fig. 5), Y until the point 41 of the pawl 35w1ll bebroughtinto position adjacent the hook 40 of the pawl 34. At this time the pawl 34 will have passed free of the frame portion a 37. The spring 38 will then be efiective torock the pawl 34 about its pivot 36 in a clockwise direction causing, the hook portion of thepawl 34 to engage and look over the point 41 of the pawl 35. This will hold the face 42 of the pawl .35 rigid against the under side of the lip 20 of the .key coupler 17. When the keys :10, 11,12 and 13 have completed their movement in one direction, pressure is released on the outer end of the, keys and by reason of the weight of the key coupler 17 the rear ends of the depressed 'keys are moved downward toward normal position. As the key coupler rests on the keys 10 and 13 this downward or counter-clockwise movement of the keycoupler '17 will be applied directly to the key. However, as the cut away portion 33 of-the keys 11 and 12 does not permit of the key coupler 17 contacting directly with said keys, the lip 20 resting on the face 42 of the pawl 35 Wlll perform the function of restoring the keys 11 and 12 to normal position. As the keys l1 and 12 reach their normal position a beveled rear face 46 formed on the lower endof the pawl 34 will engage the curvedforward edge 47 of the frame portion 37 and upon. the continued restoring movement of the keys 11;

and 12 the pawls will be rocked 'counterclockwise about their pivots 36 thereby 'dis-' engaging the hook' ortion 40 from the point 41 of the pawls 35, in the osition shown in Fig.v 5.

It.w1ll be noted that when a key 11 or 12 has been partially depressed a wall 48 at the rear end of the cut awe portion 33 will engage the rear edge of e lip 20 of the coup er 17, and because of the intersecting arcs of movement of the keys and coupler; the raising of the rear edge of the coupler 17 by a key 11 or 12 is prevented.

The keys 11 (Fig. 1) comprise digit keys 1 to 9 inclusive which are the units or penny tax keys and the keys 10 and 20 which are 0 parts then being again tax key 12. The arms of the yokes 50. and 51' are pivotedon the shaft 14- The right hand arm of both of the okes 50 and 51 as shown in Figs-1, 5 and are formed with downward extensions52 to which are connected springs 53 and also secured to a forward portion of the frame of the machine. The springs 53. normallytend to draw the lower ends of the arms 52 forward thereb to holding the okes 50 and51 in contact with the'upper eces of the keys 11 and 12.

Lock 0;- m keys. Pivotallymounted upon the shaft 14 are .25 the arms 54 Of a third yoke 5 ig 5,

7 and 8) which normally rests upon the yokes 50 and 51. The left hand arm 54 has a downwardly extendin arm 56 to which is connected a spring 57 w ich normally holds the yoke 55 in contact with the yokes 50 and 51. The arm 54 is further proyided with a forwardly' and upwardl extending arm 58 which is connected by a It 59 to-a forward arm 60 of a lever 61 vdtsd on the shaft 14.

The lever 61 exten upwardly and 'rear- .wardly as shownin Fig. 5,.and has its upper rearward end normally in the path of movement of an obstruction 62in the form of a small cam. The obstruction 62 is pinned to the rotary shaft 21. -A notch is shown as formed in thefrear end of the iever 6% far a? o 'reventi a reease 0 't e revolhti ii ghaft m by movement of the 12 less than the required initial keys 11yor movement.

Itwill be seen from the construction which is above described that as 10 as the keys Hand 12 remain in their an e ressed positions the level-"61 will stand in t e posit on shown in F ti -thereby obstructing the movement of e obstruction 62 thereby locking the shaft 21 against movement. Conse-v l quentl any attempt to depress a key 10 or 13 wi out first artially depressing the key 11 or 12 will frustrated, as the key coupler 17 cannot be then rocked clockwise (Fig. 6) to rotate the shaft 2.

- I either a key 11 or 12 is first depressed, as abovedescribed, it wifi enga and rock its a'p ropriate yoke 50 or 51, t e rockin of who yoke will rock the. oke about t e'shaft. 14, the'reby rocking ever 61 to carry its upper rearward end. outof'the path of movement of theobstruction- 62 P thereb ypermitting therotationof the shaft mesa artially' 21. This in turn will permit the operation of a key 10 or 13. When a key 10 or 13 is then depressed, the key coupler 17 will be moved clockwise about its pivot 18 thereb cou ling all of the keys 10 or 13 which ave n operated so as tomove as a unit and also j cause said cou or 12 which liavev been operated, thereby completely operating said latter keys.

Indicating mechanism.

Slidably mounted in the frame-plates '63 and 64 just above the rear end of each of the keys I0, 11, 12 and 13 isanin icator rod 65 which carries at its upper en an indicator tablet 66 of a type fully shown and de': scribed in the hereinbefore mentioned Carneyand Cleal patents. i The; indicator rods 65 are held in lowermost position by sprin s 67 so that the lower ends of all of the in her 17 to engagethe keys 11 cator rods 65 are'in" contact with the rear ends of the keys 10, 11,12 and 13. Each of.

' the indicatortablets 66 bears a special character or characters which are preferably identical with the character or characters appearing on the forward ends of their appropriate keys 10, 11, 12 and 13. When an of t e keys are depressed, the indicator rod: 65 will be elevated against the tension of the sprin 67 carrying the tablets 66'upward unt a projection 68 carried by the\indicator rods 65 passes above a rocking bail 69 pivoted at 701- at eitherend to the side frames 15 and 16. -The construction and operation of bail is old andwell known j in the art and will not be described in detail here. Its purpose is to hold the indicator rods 65 appropriate to the depressed keys in elevated position between operations of the machine so as to sustain an indication between operations of the machine thereby showing which keys were depressed in theprevious operation. It will thus be seen that when any one of the keys 10, 11,112and 13 is depressed the pro er indicator tablet 66 will be raised and publicly exposed through sight openings in the'cabinet which are commonly provided in cash registers. so as to indicate which of the keys 10, 11, 12 and 13 have been operated.

Totalisera. t V v As hereinbefore stated linthe .early partof the description, the machine is prov ded with-two totalizers 7 O'and 71. The totalizer 70 (Fig. 5)- normally lies at the left hand end of the machine ust. above the tax-keys 11 and 12 (Fig. 5) but isomittediromFig. 1 for the sake of clearness; in showing the. .yokes 50, 51 and 55 which are operated by the ,taxkeys ll and 12.

The' talizer 71 (Fig. 2

The. construction and o liestotheright pration of i mass two totali zers 70 and 71 are identical and for convenience the left hand 'totalizer 70 will be hereinafter called the tazi totalizer and the ri ht-hand totalizer 71 will be here- Pivotally mounted at 78 (Figs. 2 and 5) to each of the keys and 11 is an upwardly extending member 79 which is formed near its upper end with a notch 80. The notches 80 of the various members are located different distances from the pivotal point 8 of the menibers 79 thereby enabling the giv- Y suflicient to enab e any one skilled in the art to understand the operation of total- 1 for the units of cents keys 10 is loosely right hand end thereto.

ing of graduated movements to the registering mechanism of the machine by the operation of the various keys 10 and 11.

As the construction and operation of the tax and purchase totalizers is identical it is thought that the description with reference to the urchase totalizer will be izera Referring to Fig. 2vthe notch of the member 79 is adapted toengage a cross rod 81 when any one of the keys 10 is depressed. The cross rod 81 is carried by a rocking frame 82 pivotally mounted upon a rock shaft 83 supported in the side frames 15 and 16. A rocking frame 82 is provided for each of the three groups of keys 10 ,that is,

one for the P61111108 group, com rising the keys 10, numbered 1 to 9 inc usive; one frame for the tens of cents group, com rising the keys 10 to 90 inclusive; and a t ird frame for the dollars group comprising the I It will thus be one and two dollar keys. seen that when ,any one, of the keys 10 is depressed it will -iock itsap ropr'iate frame 82 different distances accor ing to the location of the notches .80 of their appropriate members 79. The-frame 82 (Figs. 1 and pivoted. on the rock shaft 83 and has fast t its left hand end a rack segment 84. The frame 82 appropriate to the tens of cents keys 10 has. fast thereto on its a-similar segment 84. The frame 82 appropriate to the dollars keys 10 is pinned as at 85 to the pckshaft 83, consequently any movement of the frame 82 of the dollars keys 10 will be transmitted to therock shaft "83. Al'so inned to the rock shaft 83 as at 86 (Fig.1 isathird rack segment 84 to which is transmitted rock'- ing movements of the frame 82 of the dollar keys 10 through shaft 83.

It will thus be seen that :the operation of the pennies, dunes and dollars purchase keys the medium of the rock 10 will be transmitted to the three rack segments 84 (Fig. 1?) through the medium of the appropriate frames 82. v The purchase totalizer is' substantiall identical in construction and operation with the totalizer shown in theCarney and Cleal atents hereinbefore referred to, but. will described briefly as follows: i Purchase tataliser. I

The purchase totalizer 71 com a: plurality of totali'z'er elements 90 in t eform of wheels rotatably mounted upon a shaft 91 suitably sup lilted in the'rocking totalizer frame 92.

e wheels 90 bear on their peripheries,

stamped numerals running 1 it will be noted that the totalizer com-. prises seve'n.of- 'such wheels 90. The three wheels of I lower numerical order, that is the three wheels to the right in Fig. 1 are I from 1 to 9 and 07" inclusive. In Fig. a

each fast to a pinion 93 each of which is normally in operative alinement with one of the re stering rack segments .84. In the norma position of the frame92, however, the pinions 93 are out of operative engagement with the r isterin shown in Fig. 2.

segments 84, as' I pon t e rotation ,of the shaft 21, a'cam 95 rigidly mounted thereon will coo rate with anti-friction rollers 96 carried yuan arm 97 o ratively connected to the roe 'ngtotalizer ame 92. When the shaft 21 is rotated upona depression of one of the purchase ke s 10, the cam 95 is ef-. fective to rock e totalizer frame 92 through the medium of the arm .97, so as to carry the purchase totalizer rearward to'engage the totalizerpinions 93 with the registering rack segments 84 before any movement ofthe registering rack se ents 84 and the frames 82is begun. is enment of the pinions93 with the registerin rack ents 84 is continued throughout the I ownward movement of the outer ends of'thekeys 10. At the completionof the downward movement of the outer ends of the keys 10, which is the end of the registering stroke of .the keys, the

t e. pinions 93 from the registering rec se ents 84. During the returnmovement o the keys 10, therefore, and the consequent restoring movement of the registering rack segments 84, the pinions 93 will re.- main disengaged so that the return movement of the se ents 84 will have no effect upon the totahzer elements.

' Suitable transfer mechanism. comprising the transfer pawls 961 carried b rocking arms "971, which latter are operate by cams 98 fast on the-rotating shaft 21, is provided for performing the function of carrying from the totali'ze'r elements of lower order urchase totalizer' forward to disenga 1 I "40 the side frames 15 and 16.

. also has fast thereon a pinion 103 which.

described in the hereinbefore mentioned Car my and Clea] patents. It will thus be seen that upon each actuation of one or more of the purchase keys 10, the urchase totalizer will be rocked to engage t e pinions of the l0 totalizer with the registering rack segments 84 so as to enter upon the purchase totalizer the amount of the purchase asrepresented by the keys depressed. Means is also shown for resetting the totalizer wheels to zero by rotating the shaft 91 but as thisjs old and well known in the art it will not be described in detail here. a

I Tam totalz'zer. Theo ration of thetax totalizer will be brie thought'unnecessary to '0 into the description in detail,,in view 0 the fact hereinbe-- fore mentioned that the operation of the 2 tax and purchase. totalizers is identical. The units tax keys 11, runnin from 1 to 9 inclusive, carry members 79 aving graduated notches 80, as shown in Fig. 5. The members 79 cooperate with rocking frames 82 similar in construction to the rocking frames for the purchase vkeys. There are two rocki shown in l ig. 1. The eft hand rocking flllame 82, as shown in Fig. 1, is pivoted on t e right han side a segment 160 (Figs. 1 and 5:. The segment 100 has rackj teeth formed a u'ansv shaft l02su1tabl mounted in e shaft 102 meshes with a registering rack segment which has'been numbered 84 as it is con- I structed and. operated and rforms' the g 46 same function as the. registering segmeiits 84 for the urchase.totalizer. D

The right and frame 82 for the penn tax keys 11 is also pivotedon a rock sha 83' and has fastto its right hand end asimi- 0 hr segment 100. This as .nt 100 mesheswith a pinion 104 *pinn to a transverse shaft suitabl su rted in the side framee lland 16. Y e

The platen v ward end-of an arm 128'pivoted at 194 on a asses J V 5 and in construction is identical with the purchase totalizer, the same'gmechanisin being employed for engaging the totalizer pinions with the registering rack segments 84, as in-thecase ofthe purchase totalizer. The mechanism for engaging the tax tota lizer', however, has been omitted for the tax keys 11 will be elevate to indicate the.

amount of tax which v is registered for each Printing mechanism- For the p of printing upon a detail record strip to chine the amount of the purchase, together with the tax to be assessed, the movements of the ,re 'sterin se ents for both the tax an pure ase totalizers are trans-- mitted to printing wheels 110 the amount of tax, and 111 for printing the amount. of the purchase. Referring to Fig. 2, each of there ring segments 84 of the purchase tot 1-12, the left hand inion being faston a cross shaft 113, wh' e the other two pinions are fast on the. left hand ends of nested sleeves 114 sup rted on the shaft 113. The shaft 113 and seeves 114 extend to the right (Fig. 1) through the side frame 16 and have fast on their rig t hand ends the printinglwheels or elemen 111..

The wheels lloand 111 bear on 120. Just beneath the their peri heriee typewhefis 110 I 111 (Fig. 3) is a platen an Impression,

121 for the pu of from the rais t e 120, on a detail'strip- 1 is carried on 'theforrates with projection 126 carried by the in contact with the peripherv ofthe scroll p aten arm 123. Interposedv between the arm 123 and a lug 127 on the printer frame 1251 is a spring member 128 which serves to hold pro ection 126 of the platen arm 123 cam 125. The shaft 21 is rotated counterclockwise, as viewed in Fig. 3, and it is obvious that as the shaft 21 rotates. the portion of the scroll cam 125 of increasing radii will serve to rock the platen arm 123 coun ter-clockwise about its pivot 124 until the cam reaches its point of greatest radius. At. this time the downward or registering stroke of the forward,end of the keys 10,, 11, 12 and 1 3 has been completed and the.

wheels 110 and 111 have been adjusted to positions representing the amount of tax and the amount of purchase. Then upon the continued rotation of the shaft 21 the high point of the scroll cam 125 will pass the projection 126 of the platen arm 123, thereby permitting the-spring member 128 to act to throw the lplaten 121 against the adjusted ty e 120, t ereby causing an impression to made on the detail strip122.

The detail strip 122 is led from the supply roll 129 about two studs 130 on the printer frame 1251 t a receiving roll 131. The receiving roll 131 has fast on its left hand side a. ratchet wheel 132. Cooperating with the ratchet wheel 132 is a hook arm 133 having its hook end 134 held in engagement with the ratchet 132 by a spring 135. The arm 133 is pivotally mounted upon an arm 136 fast on the right hand end of the trunnion 18 of the key coupler. 1 Consequently, the arm 136 receivesa' reciprocating movement on the reciprocating movement of the key coupler 17. This reci rocating move-' ment of the arm 136 actst rough the arm 133 pivoted thereon to rotate the ratchet 132 and receiving roll 131 the distance of one tooth of the ratchet 132 in a counter-clockwise direction. A spring held pawl 232 is provided to prevent retrograde movement of the receiving roll. Consequently, this advances the detail strip a" single space at eadi operation of the machine, so that the printed items are printed successively on the detail strip in the order that they are entered on the totalizers, as shown in Fig. 1

An inking ribbon 180 is provided for giving a properly inked impression on the detail strip 122. The ink ribbon 180 is a continuous'ribbon passing about an ink roll 190. a guide stud 191. a roll 292 on the stud 192 and a guide roll 193. In order to keep the proper tension on the ink ribbon 180 there is provided'a roll weight 194 carried by a frame 195 pivoted on the stud 296. This weight bears on the ribbon and holds the ribbon taut as shown. i Y

For. the purpose of holding the positioned typealined whilesan impression is being taken, each of the type wheels 110 and 111 has fast to its side a star disk 197. The star disks 197 have cooperating therewith a series of alining fingers 198 pivotally mounted at 199 in a frame 196 which is pivoted on the stud 192. Springs 297 are provided" for holding the fingers 198 yieldingly in cont-act with the star disks 197 when they arethrown into engagement therewith. For the purpose of throwing the-alining fingers 198 into engagement with the star disks 197. the frame 196 is formed with a two-armed downwardly extending member 200 which cooperates with a cam 201 fast on the revolution shaft 21. The cam 201 is so formed that at the proper time during the rotation of the shaft 21 which is immediately upon the completion of the adjusting movement of the type wheels 110 and. 111, said cam will be effective to rock the frame 196 "through the medium of the member 200 to engage the alining fingers 198 with the notches formed in the star disks 197. After an impression is taken and before the keys start on their return stroke, the frame 196 v is rocked clockwise (Fig; 3) to disengage the locking fingers from the notches in the star disks 197 The printing wheels 110' and 111 are spaced apart so that, as shown in Fig. 4, the printed impressions will appear. in colums, the left hand column 137 representing the amount ,of the purchase and the right hand no sale key 13. Immediate y to theright. of the entry 139 is a similar. entry of two zeros the tax column, which entry has been .marked 140. As no purchase was made and the no sale key 13 was used, no tax 1 would be assessable, therefore the no tax key 12 was depressed and consequently the tax pr nting wheels 110 have been caused to print two zeros on the detail strip. Just above the tax entry 140 is a similar entry- 141, comprising two zeros. Adjacent these two zeros is an item marked142 which shows a purchase of 30. As this was for the sale of non-taxable goods. the printed entry pressing the no tax key 12 and ther pressing the 30 purchase key 10. v

shows that they machine was operated by .of an arm. 154

v tax key has been operated.

.The detail strip 122 therefore'shows in every instance the. amount of the purchase accompanied by an item in the right hand column showing the amount of .tax assess- 5 able for that purpose in the case of a taxable sale, whilezeros are printed when the no tax? key is used 1n connection with the transaction involving non-taxable articles.

For the purpose of showing the number of times the machine has been operated, an additional step-by-step counter 160 is" pro-,

This counter 160 is operated by a \niultiple tined pawl 161 carried by the upper end of an arm 162 also pivoted on the short shaft 55 ""1 having at its lower end a pin upper e of a lever 165 pivoted "on the cross shaft 14 which supports the keys 10, 11, 12 and 13. At its rear end the lever 165 is formed with a hook 166 which hooks over 20 on the key coupler 17. Conse the li quent y, upon 'each actuation of the key coupler 17, the lever 165 is rocked aboutthe shaft 14, and through the medium. of the arm 162 and the multiple tined pawl 161, the

For the purpose of keeping an account of the numbe'r of times the .no' tax key 'has beemoperated, the no tax key is provided no sale key. This arm 158 for the no tax-key is identical in construction with that of the no sale key and cooperates with a similar pin 156 carried by an arm'171 fast.

which carriesa multiple tined pawl 175 which actuates the wheels of an additional step-bystep counter. 176. C0 uently, upon each o ration of thefno tax y 12the counter 1 6 will-be advanced one step or unit and will show the number of times that the no aft 155 163 p 'ecting into a slot 164 formed in the counter 160 is advanced one step or. unit'- upon each operation of the key coupler 17.3

with an arm similar to the arm 158 on the General operation.

The general operation of the machine, therefore, comprises the following steps:

Supposing the machine to be used in a soda fountain where a tax of one cent is to be assessed for each ten centsof purchase or fraction thereof. Taking as an' example the purchase of a five-cent soda, the open ator will operate the machine as follows:

For a fivecent soda the tax will be one cent, consequently the one-cent tax key 11 1s..depressed partially and by the mechanism hereinbefore described that ke is held in'partially operative position. his partial operation of the key 11 releases for operation the rotary shaft 21. Consequently the purchase keys 120 may then .be operated Tto complete the operation of the emachin'e. The purchase being five cents,

the operator presses. the five-cent purchase key 10. The'operation of the ke 10 will act to complete the operation oft e 'previously and partially The one-cent tax Wlll be properly registered on the tax totalizer 70 and the amount of the purchase, five cents, will be properly registered upon the'purchase totalizer 71.

At the same time, the indicator appropriate to the one-cent tax key 11 will be elevated and publicly exposed and the five-cent purchase key '10 will likewise be elevated. At the same time, the printin elements will be adjusted so as to print Eve cents-in the purchase column and one. cent in the tax column, as indicated by the first item atthe ti op. of the columns in the detail strip in g If a sale 'isthen made of goods which is not taxable, the operator first presses the no tax key.
