This invention relates to a new and useful improvement in cash registers, the object being to construct a machine of the character described in such manner that there are comparativelyfew parts and therefore the machine may be cheaply manufactured.

One feature of my improved machine is the utilization of a single lever which is universally mounted so as to swing horizontally opposite the number to be registered, and then move vertically to register, indicate and record said number.

Another feature resides in thepeculiar construction of the controlling plates which cooperate with the handle whereby one or more of said controlling plates are operated to efiect such registration.

Another feature of the invention resides in the employment of a. composition key whereby a large number composed of one or more smaller numbers may be registered and recorded, as separate numbers, but indicated as a single number.

Another feature is the provision of means whereby when the composition key is depressed, the drawer cannot be opened until all of the component parts of the number have been registered, indicated and recorded.

Separate counting mechanisms are provided to register the numbers indicating different amounts of sales and the number a detailed View of times that the handle is operated to open the drawer when no sale is made.

My invention consists also in the construction. arrangement and combination of the several parts. all of which will be herein after pointed out in the claims.

In the drawings: 1 indicates the side frames of the machine which are connected together by suitable cross bars, and in which the shafts or pivot rods are mounted. Be:

tween these side frames is arranged a drawer which determine the position of the operating handle. The operating handle is indicated at 6 and is provided withgan upwardly opening slot, see'Fig. 4;, at its upperend to embrace the outwardly extending flange of plate 5, the button or head of said operating handle being provided with an indicating point designed to be placed opposite the amount to be registered; The operating handle is pivoted at 7 by means of a horizontally disposed pivot pin to a swinging plate 8, which plate is provided with vertical pivot points cooperating with the cross bars 9 and 10. The rear end of the operating handle 6 carries a spring-held tappet 11 which cooperates with a notched plate 12, carried by the rear end of'the plate 8, so as to compel a full stroke of the operatinghandle in a mannerwell known. In order to prevent the operating handle from bein operated when moved too suddenly, or w en being struck a blow, as for instance by the falling of a package thereon, I pivotally mount a restraining plate 13 upon the plate 8 which plate has a recess for coiiperatin with a pin 14 on the operating handle. When the operating handle is properly operated, the pin 14 rides up the inclined upper edge of the slot permitting the plate 13 to swing on its pivot until said plate13 strikes a pin 15 on plate 8. The rear .end

of plate 13 is bent under the operating handle,

so that as the operating handle is restored to normal position, the plate 13 is moved in proper relation to the pin M, j When the operating handle is moved too suddenly, as when struck a blow, the plate 13 will prevent the operating handle from being operated asthe relation of the pin let to the upper edge of the recess is such that the operating handle is locked in position when too great a downward pressure is exerted on its forward end. 16 indicates a rocker plate con centric with respect to the pivotal axis ofmovement of, the plate 8 and pivotally mounted upon castings which connect the cross bars 9 and 10, the pivotal point of this rocker frame being co-incident with that of the operating handle. The rear ends of this rocker frame are provided with weights 17 which I prefer to use in place of springs because they exert a constant energy upon the rocker frame to restore the same, where- .ward movement of the member 16.

as springs would exert a variable pressure upon said frame.

The rocker frame may of course have springs connected to it either to assist the weights in their action, or to constitute the sole restoring medium for said rocker frame.

The operating handle is provided with an L-shaped extension 6 (see Fig. 7 which extends under the rocker frame so that when the operating handle is depressed, the rocker frame is moved with it and'when said handle is raised, the rocker frame will also be positively restored to position, although in practice the operating handle "is depressed and then released, the weights or springs connected to the rocker frame'res'torin the operating handlef O ne member of the rocker frame is extended rearwardly as indicated at 1 6 where it is provided with a tappet 17 carrying a roller-on its end which cotiperates with a beveled lower edge of a lever 18 pivoted to the adjacent side frame so as to rock said lever on the up- 18 is providedfwith a shoulder 18 so that when the roller on the tappet rocks said lever-and comes to a position opposite the shoulder, it will permit the lever 18 to remain in its normal position on the down stroke of the member 16% The purpose of this rocking lever 18 is to release the indicating cylinders to zero so that they may be reset to indicate a number being'registered in the machine, as will hereinafter more fully appear. In addition to releasing the indicating cylinders, the rocker Lever frame 16- also operates the paper feeding I mechanism and the carrying mechanism of the tot-alizers, as will hereinafter appear.

I will now describe the. means for introducing numbers into the registering mechanism and will first direct attention to Fig. 2 wherein it will be seen that the plate 5 at the left bears the characters 01 to 04 inclusive, indicating cents, so that when the pointer on the operating handle is placed opposite any of these numbers, the registering mechanism will be correspondingly operated to accumulate the proper number and the indicating cylinder is moved to indicate such number. The letters on plate 5 mean no sale and when the operating handle is placed opposite this point and depressed, the registering me hanism for indicating the number of times the drawer is opened, will be operated and the indicating cylinders returned to zero. The figures 051015, etc indicate cents progressively in multiples of 5 up to 95, and when the handle is positioned opposite any of these numbersand depressed, the corresponding number will be registered in the registering mechanism. At the right of' the character $1 and when the operating point and depressed, the proper registering Wheel will be operated and the indicating cylinder moved to indicate the registration of one dollar.

Referring now to Fig. 23, 19 indicates the units plate which is fixed to a shaft 20, said plate being connected by a sleeve on said shaft to a segment- 21 which segment is dapted to be rocked forward when plate 19 raised by the operating handle.- When the operating handle is, moved to indicate the units, cents, the rear end of said handle is located under one of the steps marked 1, 2, 3 and 4 so distanced from the rear end of the operating handle that when the handle engagesone of said steps, the units plate will be raised so as to rock the segment 21 the distance of 1, 2, 3, or 4 teeth. Assuming that the handle is positioned to open the drawer without registering the number (no sale) the rear end of the operating handle will be located opposite a notch 19 in the units plate and hence said plate will not be raised upon the operation of the handle. 19* indicate projections or shoulders on the lower' edge of theunits plate, each of which, when engaged by the operating handle and raised,..will move the segment 21 the distance of five teeth. Thus in the registration of progressively higher numbers in multiples of five, each number containing five units will, when registered, cause the units plate to be lifted a distance to register five units in the totalizer wheel; and each number containing no units, will, when regis' tered by operating the'handle, permit the units plate to remain stationary as the operating handle will in the registration of such numbers, be located opposite one of the recesses 19 1 In Fig. 22 I have-shown the tens controlling plate 22 which is pivotally mounted upon the shaft 20. This tens plate is provided with a series of shoulders on its top and bottom edges, thatat the extreme right I in Fig. 22 indicated at 22 being so posi-- tioned with respect to the rear end of the opcrating handle that when'said handle is operated, the tens plate will remain stationary. This edge 22 coincides with the are of. movementof the operating handle from and including .05 to the right of No sale to and including $.01. The next step 22 will,

i when the operating handle engages the plate to 'lift it at this point, cause the tens plate to be raised so that it and its conjoined segment 23 will move forward a distance of one space thus registering F 1 in the tens registering wheel. These steps progressively increase the extent of movement of the tens plate, until the lowermost step is reached which, when the operating handle cooperates therewith, will cause the segment 23 to be rocked forward a distance of nine spaces.

24 indicates an'arm pivotally mounted on shaft 20 and whose rear end is bent as shown in Fig. 21 so that when the operating handle is moved to the extreme right'by the operator its rear end will be positioned under the bent end 24 so as to raise said plate a distance of one tooth to register one dollar in the proper registering wheel. In doing this the operating handle'of course does not operate either the tens or the units plates. Plate 24 has asegment 25 connected thereto for cooperating with the units dollar pinion of the totalizer.

The totalizer wheels are mounted upon a grooved shaft 26 havingsuitable bearings in side frame plates 27 pivotally mounted at 28 toloracket extensions on the cross bar 9. This frame is rocked rearwardly at the initial depressing movement of the handle by means of a rocking frame 29 (seeFig. 8) having a notch in its periphery which notch cooperates with a roller on an end of a tappet 30. The tappet 30 is carried by an arm 31 pivotally mounted to the side framing 2 and having a lateral projection 31*,on its end which extends over arearward extension on one of the frames 27. The frame 29 is rocked by means of a link 32 connected to the rocker bar 16. When the handleis depressed, the roller on the end of the tappet 30drops into thenotch of the frame 29, and spring 33 rocks the arm 31 and holds the totalizer frame rearwardly until the frame 29 passes under the tappet 30 and permits said tappet to rise to its normal position. In rising the tappet 30 which is provided with a lateral projection 30 engaging the arm 31 will, by the cam face 29 on the rocking frame, lift the frame 31- and restore" the totalizer frame to normal position. Inthis manner the totalizer wheels are thrown into mesh with the

segmental racks

21, 23 and 25 at the commencement of the downward movement of the operating handle and held in mesh therewith until said handle starts to rise with thecam face 29 and will lift the totalizer wheels out of engagement with their racks and prevent retrograde rotation thereof.

The counter for indicating the number of times that the drawer is opened-and no sale made is shown in Figs. 10. and 11 and consists of the indicating wheels 34 hearing numbers from 1 to 9 inclusive and zero on their peripheries to which wheels are conjoined ratchet wheels 39shown in Fig. 10. The Wheel at the right in Fig. 10 is the units wheel and has a deep notch 39 while the tens wheel shown at the center in Fig.- 10 has a shallower notch 39". An operating pawl 40 is carried by an arm 41 pivotally mounted on a shaft 42 and normally'held against the units wheel by means of a spring 43. Thus, whenever the arm 41 is vibrated, the pawl 40 is lifted and its tine 40" will operate the units wheel until it drops into the deep notch 39 when the second tine 40 will engage the tens wheel and move the tens wheel a distance of one tooth. When the tine 4O operates in the ordinary way with its ratchet teeth, tine 4O which drives thetens wheel and the tine 40 which operates the hundreds wheel will beheld out of engagement with said wheels respectively.

When the deep notch in the units wheel ratchet is reached then the tine 40 may operate the tens" wheel the distance of one tooth or, if the tine 40 drops into shallow notch 39, then the tine 40 will be brought into engagement with the hundreds wheel and operate the latter the distance of one tooth simultaneously with the operation of the tens and units wheels.

The means for operating the tined driving pawl for the above described counting mechanism comprises a bail-like frame 44 pivotally mounted on shaft and having a rearward extension 44, see Figs. 1 and 20 which rearward extension is provided with a bent rear end designed to be engaged 'by the operating lever when the same is positioned at No sale. Bail 44 engages a cam face on the rear end of lever 41, see Fig. 7, so as to vibrate said lever every time the handle is operated when positioned at No sale The totalizing wheels which are operated to accumulate the various registrations are indicated at 45, see Fig. 9, the indicating wheel at the extreme right of the series reging mechanism about to be described is operative to carry from lower to higher orders. 3

Referring now to Fig. 11 wherein a segment 21 is shown out of mesh-with its co-' operating pinion, it will be observed that when the frame 27 is rocked rearwardly, it will engage pinion 46 conjoined to the ratchet wheel 46 with a segment and rotate said pinion, its conjoined ratchet wheel and indicating wheel on the forward stroke of the segment. 48 indicates a restraining pawl pivotally mounted on a rod 49 having a bearing in the side frames 27, and which pawl 48 prevents backward rotation of the ratchet 46. Assuming for purposes of description that the disk 47 with its tripping projection shown in Fig; 11, is identified with the cents wheel and that the pinion ratchet wheel and indicating wheel illustrated in said figure are identified with the dimes column, it will be seen that as the tripping projection rotates, it will engage a finger or shoulder 50 ,011 a tripping pawl 50 pivotally mounted on the rod 49. This pawl is held in operative position by a spring 51. A shoulder is provided at its forward end which shoulder normally restrains a driving pawl 52 from engaging the ratchet wheel of higher order. This driving pawl as shown in Fig. 9 is provided with a lateral extension for cooperating with the tripping pawl 50.

, In the normal operation of the machine y when no carrying is effected, the carrying pawl 52 is vibrated idly by means of the following mechanism: On the shaft 42 are arms 53 upon whose forward ends are pivotally mounted carrying pawls 52. Arms 53. are

provided with downward extensions to which are pivoted tappets 54 having rollers ontheir lower ends and provided with lateral projections on their upper ends for engaging the forward edge of the arm A spring 55 tends to hold these tappets in normal position. A spring 56 holds the carrying pawls 52 in engagement with the tripping pawls 50 and the spring 51 also tends to maintain the engagement between the tripping pawls and carrying pawls. The rocking frame 29 before referred to carries cam project-ions 57 at its upper end which cooperate respectively with the rollers of thc tappets 54 of the different carrying pawls, and in order to successively carry from lower tohigher orders, these cam projections 57 are preferably arranged in a spiral series, as shown.

As the operating handle is depressed and the segment 21 is rocked forwardly to introduce the proper number into the register wheel, the tripping 'arojection will depress the forward end of the tripping pawl 50 and permit the carrying pawl 52 to be moved, under the action of its spring 56, into engagement with the ratchet identified with the next adjacent register wheel of.

higher order. At the same time, frame 29 moves rearwardly and the cam projections 57 are successively moved under and behind the tappets 54, said tappets idly vibrating to permit this. Upon the initial upward movement of the operating handle, the segments are disengaged from the registering pinions and as the frame29 rocks forwardly, the tappets 54'are successively engaged, and any carrying pawl 52 which has been released and which is in engagement with the ratchet wheel of next higher order, will be lifted and rotate its engaged ratchet wheel the distance of one tooth. All of the carrying pawls are of course thus lifted, but only those ratchet wheels of higher order will be operated by the carrying pawls which have been tripped. The other carryingpawls 52 .while lifted cannot operate their ratchet wheels because they'are held out of engage-- ment therefrom by the non-tripped tripping pawls. In order to absorb high numbers carried from actuated register wheels, I may add one-or two additional wheels, as for instance tens of dollars and hundreds of dollars as shown at the left in Fig. 9. These wheels have no pinions conjoined to them, and as they can only receive motion from a wheel of lower order and are never operated more than one step at a time, I provide the same with recesses of varying depths and effect cariying from one to theother by means of a carrying pawl 58 which operates similar to the tine carrying pawl 40 before described with respect to the counting indicator To restore the registering mechanism to zero position, I provide the end of shaft 26 with a hand wheel 60, see Figs. 1 and 2 and mount in each of the indicating

wheels

34 and 45, a spring-pressed pawl 61, see Fig. 15, which pawls are designed to fall into a longitudinal groove in the shaft 26 and rotate the disks in the same direction as when said disks are being driven by their segments. The pawl, however, does not prevent the disks from continuing to rotate after reaching zeroposition, as the pawl is lifted out of the groove. I

In order to prevent the operation of the handle when the resetting handle is in other than home position, I mount a notched disk 62 on the opposite end of shaft 26, (see Fig. 8) which notched disk, when the shaft is rotated, engages the upper end of a swing ing plate 63 pivoted at 64 and carrying a bar 65 which lies under the carrying pawls 52, so that when said plate 63 is rocked, the carrying pawls are held out of engagement with the wheel. A rock arm 66 lies against the upper end of plate 63 and when said plate is rocked forwardly, the rock arm 66 is carried with it and being mounted upona shaft 67, will rockv said shaft against the tension of its restoring torsional spring 68. The shaft 67 carries hooked arms 69 which are designed to move under pins 7 0 on each side member of the rocker frame 16. In this manner, when the plate 63 is rocked, the rocker frame cannot be depressed and hence the operating handle is locked against movement.

To arrest the shaft 26 in zero position, I mount a bell crank lever 71 on the frame 27 which bell crank lever has a stepped upper end for cotiperating with a pin 72 on the disk 62 when said bell crank lever is rocked forwardly. The horizontal member of the bell crank lever extends under the'plate 63 and when said plate is rocked, the stepped upper end of lever 71 is placed in the path of the pin 72. A spring 73 holds the hori-- zontal member of the bell crank lever against plate 63 so that when said plate is restored to normal position by dropping into the notch in the disk 62, it will engage the rear edge ofsaid notch and as the restraining pawls 48 tend. to center the ratchet wheels, said ratchet wheels will be reversely rotated by the centering restraining pawls practically the distance of one-half a tooth, which reverse rotation releases the stepped upper end of the arresting bell crank lever 71. By this construction, the rocking plate 6 3 places the arresting bell crank lever in position in the path of said pin to arrest said pin when the shaft 26 has been rotated onehalf a tooth in excess of one complete revolution. Then, when the plate 63 is released, it will permit the lever '71 to be returned home, and .a one-half tooth backward rotation of disk 62 will release the upper end of the arresting lever 71 and permit said arresting lever to move under and behind the pin 7 2, as shown in F ig. 8.

The drawer releasing mechanism is best shown in Fig. 7 in which 7 L indicates a hooked extension on, the rocker frame 16 which is adapted to coiiperate with a pivoted tappet 75 mounted on a lever 76 pivoted at 77. The rear end of this lever is gaging a second lever 78 pivoted at 79, the

' rear end of which is provided with a shoulder which lies in front of the rear wall of the drawer when the drawer is closed. As the operating handle is depressed, the hooked extension 7e; engages under the tap pct and the handle rises, the tappet 75 is raised and the drawer is released. To sound an alarm when the drawer is opened, I provide the rocking frame 29 with a hooked extension 80, see Fig. 8, which, as the frame 29 is rocked rearwardly, draws backthe fiat spring 81 carrying the bell hammer the are of movement of said hooked extension 80, releasing said spring whereby the hammer strikes the bell 82 and sounds the alarm. On the forward rocking movement of the frame 29, the hooked extension again becomes engaged with the upper end of the flat springs 81.

To operate the indicating cylinders: I shall first describe the manner of operating the Cash and No sale cylinder provided with these'words, which are exposed through suitable sight openings at the front and rear of the machine. This cylinder is indicated at 83, see Figs. 2, 3 and 4, being loosely mounted upon a shaft 84 and car-' rying a ratchet wheel 83 conjoined thereto. This ratchet wheel coiiperates with a restraining pawl 85 pivo-tally-mounted on a. rod 86 and connected to a suitable spring whereby it is yieldingly held against the ratchet Wheel.

Referring now to Fig. 20, it will be ob served that the lever 44* is provided with a pin or roller operating in a slot in the lower end of a rod 87. This rod is connected to the cylinder 83 and when the operating lever is depressed to open the drawer without registering an amount in the totalizers the rod 87 is raised and rotates the cylinder 83, so as to exhibit No sale through the sight openings. The restraining pawl 85 holds the cylinder 83 in this position.

-When the operating handle is moved to register an amount in the totalizers, the tappet 17 a on the rear endof the extension 10 of the rocking frame, vibrates the lever 18, causing the upper 'end thereof, having a slot and pin connection with a rock arm 88, to rock shaft 89 which shaft carries an arm 90 having a bent upper end which, when the arm 90 is rocked forwardly, engages the restraining pawl 85 and releases the ratchet of cylinder 83. vThe weight of the arm 87 connected to one side of the cylinder 83 rotates said-cylinder, so that the word Cash appears opposite thesight openings, the

movement of the cylinder in reaching this position being determined by'the slot in the lower end of the arm 87- and when the arm 90 rocks rearwardly the restraining pawl 85 is again permitted to engage its ratchet.

The dollars indicating cylinder is shown in Fig. 18 at 91 and is conjoined to a baillike extension 92 whose opposite end is loosely mounted on the shaft 84 and conjoined to a pinion 93. A torsional spring 94 arranged on shaft 84 tends to restore the cylinder 91 to zero position. The segment 95 meshes with the pinion, said segment being loosely mounted on a shaft 86. The lower extension of the segment is provided with a lateral projection 97 which cooperates with a ratchet toothed segment 98. This segment 98 is operated by a pawl 99 mounted on the lower end of a pawl carrying arm 100 swinging from the shaft 86. This pawl carrying arm is connected by a link 101 with the segment 25, so that at each' operation of the operating handle to register $1.00 in the totalizer wheels, the dollar cylinder willbe moved to indicate 1. The spring 102 normally holds the pawl 99 in operative position. To release the dollar cylinder, I fix to the rock shaft 89, a curved arm 103 whose forward end lies over a pin 104 on the pawl 99, so that when the extension 16 of the rocking frame is raised and rocks the shaft 89 in the manner heretofore described, the arm 103 will be depressed, so as to release the pawl 99 and permit the segment 98 to be restored to normal position. A restraining pawl 105is pivoted to the lower rear portion of arm 103 and cooperates with teeth on the ratchet segment 98 to hold the same in adjusted positions during the successive registrations of several numbers constituting the total amount of the sale, as, for instance, if the sale amounted to $1.89, a composition key is depressed, so that when $1.00 was registered in the totalizer, then $.85 and finally $.04, the several indicating cylinders would remain so as to exhibit the composition number resultin from the several operations of the ban le. The pawl 99 normally lies in-advance of-the ratchet teeth on the lower edge of segment 98 and the arm 100 which determines the normal position of the segment 98 cooperates with a lateral projection 98 on the forward edge of the segment, so that as the arm 100 rocks forward,

the segment will be moved by the arm 100 and place said segment in position, so that the pawl 99 will engage the first tooth. After this in successive operations to introduce dollafs into the machine, the pawl 99 will successively advance the segment 98 up to three additional teeth and the restraining pawl 105 will hold the segment in such advanced position, unless, of course, the sha'ft 89 rocks.

By means of the restraining pawls 105 the amount indicated on the indicating cylinders will remain exposed until another amount is registered by depressing the han- .dle when pa-wls 105 are disengaged from their ratchetson the initial downward stroke of the handle through the means which rotates shaft 89;

106 indicates the units cents indicating cylinders, which are fixed to a shaft 84, so as to rotate therewith. Shaft84 also has a pinion 107 pinned thereto with which cooperates'a segment 108 connected by a link 109 cooperating with ratchet toothed seg ments 110 operated by a pawlon an arm 111 in the manner heretofore described with respect to the operation of the segment 98.

The tens or dimesiudicating cylinders 112 are mounted on shaft 84' and arranged on each side of the dollars indicating cylinder 91. These cylinders have pinions 113 conjoined thereto with which cooperate segments 11 4 fixed to the shaft 86. Shaft 86 also has a ratchet toothed segment 115 operated directly by an arm-116 cooperating with a lateral projection 117 on the forward edge ofthe segmental ratchet 115, said arm being connected by a link 118 to the segment 23.

By the above construction, whenever units cents are registered, they are indicated by the cylinders 106, the one at the right, look ing from the front at the machine being exposed to the front, and the one at the left being exposed to the rear. The dimes indicating cylinders 112 are operated, the one at the right showing through the front,'and

the one at the left showing through the cessive operations of the operating handle,

which requires that the indicating cylinders being released, I depress a key or lever 119 arranged at the front of'the machine, see F igs. l and 4 which key is provided with a notch 119 for cooperating with a plate whereby it may be held depressed. A spring 120 arranged under the key tends to raise the same. A bell crank lever 121 pivotedat 122 in the side framing of the ma chine has its lower member connected to a link 123. The rear end of said link being slidingly mounted upon a bar 124 also pivoted at 122. This link 128 carries a lateral projection 125 at its rear end which, when the key 119 is depressed, is placed overthe extension 16 of the rocker frame, so that when said rocker frame is vibrated by the operating handle, the bar 124 will be raised. 1V hen the bar 124 is raised upon the operation of the handle, a downward extending track portion 126 at the rear end thereof is moved into position so that it forms a con tinuation of the rear edge of lever 18 and holds the pawl 17 elevated when the extension '16 is depressed, to prevent the roller on the forward end of said tappet or pawl 17 from dropping under the inclined lower edge of lever 18. Thus after setting the composition key 119, the tappet 1.7

- will, upon the first operation of the handle,

vibrate lever 18 and rockthe shaft 89, so as to release all of the indicating cylinders. The bar 124 being raised will locate the track extension in position to prevent the tappet l7 from again vibrating lever 18 during the successive operations of the handle. By virtue of the restraining pawls 00- operating with the segments 98, etc.', the cylinders will be left in their adjusted position. To illustrate: If $1.59 is to be indicated it makes no difference which amount, $1.00, $.55 or $.04 is registered or indicated first, but assuming for purposes of illustration that $1.00 is first indicated, the operation of the handle will first release all of the positioned cylinders and position the dollar cylinder to indicate 1. By moving the operating handle to and depressing it, the dimes and cents cylinders will be operated, but the dollar cylinder will not be released. Thus $1.55 will be indicated' By adj usting the handle to register $.04 and depressing it, 4 will be added to the cents cylinders, and they will stand at 9, the other cylinders remaining in their position, so that the amount $1.59 a number composed of three smaller numbers will be indicated on the cylinders; In order to hold the bar 124 elevated after the first operation of the handle in indicating a compositionnumber, I utilize the following means: The forward end of bar 124 carries a bell crank lever 127 whose vertical member is stepped at its upper end'so as to cooperate with a pin 128 extending from'the side frame 2. A spring 129 holds the bell crank lever against the pin and when the rear end of bar 124 '-is raised, this bell crank lever is depressed, so that its stepped upper end is located under the pin 128 to hold the forward end of the bar 124 depressed and its'rear end elevated. To release the bar 124 when the composition number has been indicated, Iprovide an extension 121 on the bell crank lever 121 which lies under the horizontal member of the bell crank lever 127 and when the key 119 is released and permitted to rise, this extension 121. moves the bell crank lever 127 to disengage its stepped upper end from the pin 128 and the bar 124 may return to normal position.

In order to prevent abnormal operation of the indicators when the composition key is depressed and the operating handle operated improperly, I provide means whereby the dollars indicating cylinder cannot be operated to indicate a number higher than 4, $4.99 being the capacity of the present machine.

As shown in Fig. 19., it will be seen that the ratchet toothed segment 98 has certain of its teeth cut away, so as to leave a blank space 98". It will be understood that the purpose of the composition key is to indicate the amount of the sale to the purchaser and no single indication can be higher than $4.99.

If it is desired .to indicate $4.99, the handle is operated four times opposite the dollar scale mark with the composition key depressed, then the handle is operated once to indicate $.95 and placed opposite the $.04 and depressed to add 4 to the cents indicators. .At

no time are the dimes indicating wheels in-i operated to indicate 1, 2, 3, 4, 6, 7, 8, and 9.

The space 98 on the segment 98 prevents the operating pawl 104 from moving the dollars indicator to indicate a number higher than 4. 4' being the limit of movement of this indicating-wheel. I provide other means on the cents segment 110 (see Fig. 19) in the form of a track plate 110 on the lower rear edge of the segment which, when the'segment is advanced to indicate 9, will engage the pin 110 on the driving pawl 110 and depress said pawl, so that it will be moved out of engagement with the teeth on said segment. The restraining pawl 110 prc vents backward rotation of the segment until the rock arm 89 is operated. In this manner the segment 110 may beinitially positioned by its arm 111 to indicate 5, and

- then supplementally positioned by the pawl 110 to indicate 6, 7, S or 9. lVhen in the ninth position, the pawl is disengaged and any subsequent operation of the operating handle to register cents, will idly vibrate the awl 110 which is held out of engagement with the teeth of segment 110 and hence the cents indicating wheel will remain stationary.

To hold the drawer closed during the indication of a composition number and to insure the restoration of the parts to normal position'and which were brought into operation to effect such composition indication, I arrange a tappet 180 on the lower end of the bell crank lever 121 which tappet when the key 119 is depressed is moved in front of a shoulder 131 on the drawer. Notwithstanding the fact that the drawer is released by the leverf78 upon the first operation of the handle, and permitted to move forward slightly so that the rear end of thelever 78 will rest upon the top. of the drawer, the shoulder 131 engages the tappet 130 and prevents the drawer from being opened until the key 119 is raised. The purpose of making the engagement between the bell crank lever .121 andthe drawer in the form of a yielding tappet is to permit the key 119 to be depressed to indicate a composition number when the drawer is open. Then, if the drawer is closed while the key 119 is depressed, the tappet will ride on the edge of the drawer until it drops in front of the shoulder 131 and hence the drawer cannot be again opened until the key 119 is raised.

I will now describe the printing mechanism whereby each number registered is recorded.

The swinging plate 8 before referred to has a plate 132 secured to its lower edge,

one edgeof which is provided with a series of notches cooperating with a spring pressed centering pawl 133, whereby the operating handle is held in registration with its guiding slot. The opposite edge 1s, prorided with gear teeth which mesh with a pinion. 134 mounted on shaft 135 extending through the side frame This shaft 135 carries a printing wheel 136 on its end, the face of which is provided with printing type representing the different numbers on the scale plate5. Thus, as the handle is adjusted to difierent positions, theprintingwheel is correspondingly adjusted'i As the handle is depressed, a rocking frame 137 (see Fig. 6) is operated, said frame having atone end a lateral extension 138 which lies under an arm 139. The lower end of this arm carries an inking roller 140 which wipes over the face of the type in the printing line as the handle is depressed and moves the inking roller out of the way of the platen or type hammer 142. This type hammer is carried by a rocking frame 143 havng a pm at one side whlch cooperates with a cam slot in the lower end of the plate 144 fixed to the rocking frame 137. Thus,if said frame is rocked, the lower end is moved rearwardly, and as the inking roller is moved rearwardly the platen is lifted so to' press the strip of paper against the type in the printing line. The strip of paper is fed from a spool 145 over appropriated idle rollers on each side of the printing wheel and is wound upon a spool 146. The spool 146 is rotated step by step by paper feeding mechanism which consists of a pawl 147 see Fig. 6, mounted on the rocker frame and cotiperating with a ratchet 148 on a shaft 149. This shaft carriesa gear 150 on its outer end which meshes with a gear 151 on the hub of spool 146. 'Shaft 149 also carries one of the paper guiding rollers 149 which is preferably knurled or faced with rubber. Roller 152 cooperates with the roller 149, said roller being mounted in a swinging frame 153 and held yieldingly by a spring 154 against the roller 149, so. that when said frame is depressed the rollers 159 and 152 are separated to permit the introduction of the end of the strip 'of paper.

In order to distinguish the composition numbers which are recorded, I provide means for feeding the paper a shorter distance so that any two or three numbers entering into the composition will be closely spaced. Ordinarily the pawl 147 will operate the ratchet wheel 148 the distance of two teeth but when the composition key 119 is depressed, an extension 123 on the link 123 will, by a slot and pin connection, rock a plate 155 and move the same in the path of a cam face 147" on the pawl 147, so that as the rocker frame 16 is depressed, the pawl 147'will be thrown out of engagement with the ratchet when its cam face strikes of the rocker'frame, this cam face permits the pawl to reengage the ratchet at such time as to permit the ratchet to be operated one tooth. The restraining pawl 156 is mounted on an extension of the plate 155 to prevent retrograde movement of the ratchet 148, and also serve to feed the paper one tooth when the composition key is released plate 155 is rotated.

In'Figs. 28 and 29, I have shown an ar rangement for designating the salesman who operates the machine. series of keys 160 lettered A, B, C, and D, each of which is held up by a'spring 161. The shanks of these keys are notched to cooperate with a pawl 162, whereby they are held depressed. The lower ends of the key shanks are connected to T-shaped levers 163 having depending operating extensions of different length so that when a key is depressed it willmove a bar 164, by engag- There are a r the bent forward end thereof, different distances. Bar 164 is connected to a printing segment 165 mounted alongside the printing wheel136, and this printing seg ment will, when a clerks key is depressed, position a type in printing line opposite the number recorded, to designate the clerk effecting the registration. The upper extensions of the T-levers' 163 cotiperate with a plate 166 pivoted at 166 and connected by a link 167 to a stepped lever 168 pivotedon a rocking plate 169 mounted on shaft 96. When theplate 166 is rocked forward, the stepped lever 168 is brought over a plate 170 mounted onthe extension 16 of the rocking frame, and when the handle is operated, plate 170 engages the particular step in its .path and lifts lever 168 rocking the plate 169 so that a retaining pawl 171 -may engage-the teeth on the lower edge of the plate 169 and hold the same in position. This retaining pawl is mounted upon the rock shaft 89 and whenshaft 89 is rocked,

it will release the plate 169 and permit the a segment 172 meshing with the pinion 173 conjoined to the clerks designating cylinder 174'which cylinder is exposed through the sightopenings and bearsletters A, B, C and D. When the rocking frame 16 is depressed, it will pass a tappet 175 in its path and idly vibrate said tappet. This tappet is arranged on an arm 176 fixed to a rock shaft 177 on which the pawls 162 are loosely mounted and said shaft 177 has pins 178 which engage the lateral projections of the pawls, and as the rocking frame 16 rises, it will engage the tappet 175 and rock the shaft to release the keys.

In Fig. 27, I have shown a modified construction of operating handle in which I provide means for securing a pause atthe forward rocking movement of the

segment

21, 23 and 25 of such duration as to enable the register pinions to be disengaged therefrom while said segments are at rest. In the construction heretofore described in which the rear end of the operating handle rocks said segments forwardly and also operates the rocking frame, the'parts so timed that the register pinions must be disengaged from the segments the instant that the handle starts its backward movement and where there is most motion or wear in the parts, this will possibly produce a bindvided with a lifting plate 177 pivotally connected thereto and which lifting plate cooperates with the cents, dimes and dollars controlling plates heretofore described. When the handle is operated, the bell crank lever is caused to rock and initially lift one or more of the controlling plates in its path and eventually the rear end of the operating handle will come in contact with the lower edges of said plates to drive them home and take up any lost'mo'tion in the pause mechanism under consideration. As the rear end of the operating handle starts downward the roller176 will sustain the plate 177 in its elevated position for a short period of time and hold the register operating segments forward and stationary until the register pinions are rocked out of engagement therewith.

In order to arrest the upward movement of the lifting plates, the horizontal swinging plate 8 is provided with a forward extension 8 against which all of the lifting plates strike when operated by a handle. To restore the lifting plates, the rocking frame 16 is provided with a T-shaped extension 16 lying above the arms of the lifting plates, so that if said lifting plate should strike and not fall by gravity, the arms 16 will depress them.
