ADDRESSING MACHINE -HarmonP. Elliott, Watertown, Mass.

Application July 2, 1941, Serial No. 400,770

A(Cl. 101-48) 11 Claims.

This invention relates to 'machines for printing and addressing public service and like bills and the invention is illustrated herein as embodied in a machine of the general type disclosed in United States Letters .Patent No. 1,985,247 granted December 25, 1934,1on an application led in my name.

A public service bill, such'for instanceas a Water bill, frequently consists vof several connected sections. Each bill, as a whole,has the same printed matter but different bills have diierent addresses. The several connected sections of the same bill, however, are all provided with the same address. vThe various sections are used for different purposes. 'For example, in the bill which is a product of the illustrated machine, which has three'sections, the left hand section is arranged to be cut oi 'and mailed to the customer. vThe two remainingsections of the bill vareretained at the officer and are led away.

The middle section of the bill, which section contains substantially the same data as the left hand section, is severed from the right hand section and mailed to the customer Whose bill has not been paid on or before a. due date marked on the bill sections. The right hand section is retained in the onice and is used for record purposes,a space being providedon this'. section of the bill 'in which payments made by the customer are -recorded.

/ address the back or under surface of the card to which a postage stamp may be affixed. AIt is essential, of course, that the address on the' back of the section correspond to the-address on the 'front of the card. This Asecond addressing operation on the bill section is performed prior to printing the fixedv data on the bill and from the same printing-device which applied the addresses to the front side or surfaceof the bill sections.

vOne object of the present invention, accordingly, is to provide anA addressing machine wherein the same address may beV appliedboth tothe front and rear surfaces of a bill. 'In accordance with this object, one' feature of the invention resides in mechanism'arranged to reverse the paper web between printingl operations on one-surface of .the web andprinting operaltions on the other surface of the web. 'In the illustrated machine, the Areversing.operationiis vperformed in sucha manner thatI the addressprinting `devices are fed forwardly-into andffout of the addressing mechanisms in the samedi-recgenerally upon the "construction and` operation of ybill printing and addressing lmachines.

With the above and other objects andffeatures 'in view, the invention will now'be describedffwith reference to the accompanying drawings 'in which:

The machine is provided-witha -pa-iro-reciprocating addressingmechanisms ilband J I6 operable `in'succession upon the samemddress- 'bearing printing device, herein a 4stencilf-for ment for the bill.

The machine is also provided with* feed-'cork base ,of the machine.

rupstanding bearing brackets (not shown).

verting means 28 which converts the continuous movement of the web into intermittent movement in such manner that the web remains stationary at times during the operation of the addressing mechanisms I4 and I6 and in such position that the addresses are printed on different sections in accurate registration with printed data. which is subsequently to be applied to the bill.

The means for printing the front face of the bills includes al fro-nt printing mechanism 22 which prints the common data E on the front face of the bill in register with the addresses thereon and also advances the web in a continuous manner. Back printing mechanism 24 is also provided which prints common dataFon the back face of each bill. Severing mechanism 26 is also provided which severs the completed successive bills from the web or strip. p

The various operative elements of the machine are driven by a power mechanism 28,1-ig. 4 which is of 'a well-known type and is located in the The power mechanism 28 includes a continuously rotatable motor driven shaft 38, belt-driven from the motor 3|, and a 4slower speed shaft 32, the rotation of which is 4controlled through suitable clutch controlled mechanism 34. The shaft 32 is positively connected through sprockets and a chain 36 with a short'shaft 38 which is journalled beneath the table in a bracket 40. The shaft 38 is provided with asprocket 42 which drives a sprocket 44 through a chain 48. 'Ihe sprocket 44 is fixed to an Ioperating and timing shaft 48 which is located at the rear of and above the table |0 and isjournalled in lengthwise relation to the table in The shaft 48 makes one complete revolution for each complete bill and operates all of the essential elements of the machine except the printing rolls and plat-r ens of the addressing mechanisms in timed re" lation with each other as will presently appear.

.The shaft 38 has secured to its right hand end a sprocket 54 which drives, through a sprocket chain 56 and a sprocket 58 xed to a horizontalF .g1-5

shaft 60, cam means for reciprocating the plat` ens and printing rolls of the addressing mechanism. The shaft 60 is journalled in depending brackets 62 carried by the lower surfaceof` the table. The shaft 68 makes as many complete revolutions per bill as there are sections in the bill. The machine describedvherein is designed to make a billhaving threev sections. Thus', the shaft 60 makes three complete revolutions per bill.

The paper from which the bills are made is in -the form of a web 64 contained in a roll 65 which is located adjacent to the right hand end of the table I8 and is supported in suitable brackets The roll is prevented from unrolling at a greater rate than the paper is Withdrawn therefrom by any suitable brake or other friction means (not shown). The paper web is withdrawn from the roll in a continuous manner .and at a rate which is slightly although definitely, greater than the rate of advance of the web Vthrough. the printing mechanism so that the web forms a loop 68, from which loop the web is :drawn by the web advancing mechanism without effort.

Thel web passes over a guide bar 6l, Figs. 2 and the table I8.

fixed on a shaft 1| journalled in bearings formed in the lower end portion of brackets 13 xed to the machine bed l0 which shaft is connected through Initer gears 12 with a shaft 14 journalled in a, bracket 'l5 and positively driven from the right hand end of the shaft 60 by a sprocket 'I6 which drives a sprocket 18 fixed to the left hand end of the shaft 'I4 through a sprocket chain 88. The paper web is pressed onto the periphery of the feed vroll by an idler roll 82 which is carried at the ends of arms 84 pivoted on a shaft 86 journalled in right hand extensions of the brackets 13. A lever 88 is pivoted concentrically with the roll 'IU and has a pin 90 which, when the lever 88 is moved to the right as shown in Fig. 2, raises the arms 84 and thereby raises the roll 82, thus arresting the driving of the web 64. The free end of the lever 88 is located above the table within convenient reach of the operator who is intended to operate the lever and thus momentarily arrest the feeding of the web when the loop 68 becomes too long.

The web 64 passes upwardly from the loop 68 and over the vertical Wall of a wab guide 92. An electric contact member 94 rides on the web and, upon breakage of the web, will make contact with the wall of the guideway thereby completing an electric circuit which not only sounds an alarm but also stops the machine in a manner not herein essential to explain.

An idler roll S6 is mounted in downwardly depending brackets 98 i'lXed to the under surface of the table l0. The web passes upwardly from the guide .Q2 to the guide roller 96 and thence horizontaliy from one end to the other of the machine and in succession to the various operating and printing mechanisms. The position of Athe web 64 with respect to theoperating mech- A addressing heads |4 and I6 includes also a stencil holder |08 which contains a vertical stack of stencils, |89 the successive lowermost ones of which are moved out of the holder in successive order by a pusher member ||0 and into and advanoed in step by step manner along a pair of 1 parallel stencil tracks or guideways ||2 which pivoted to the front end of a lever |3 pivoted intermediate its ends on a vertical stud 5 fixed to the table. The rear end of the lever has an upstanding cam follower ,located in the cam groove ||9 of a cam |2| fixed to the operating shaft 48. The arrangement is such that one sten- -cil is advanced for each complete rotation of the shaft 48.

VThe addressing mechanisms 4 and I6 are of usualand identical construction and are timedto operate simultaneously. It will be necessary, therefore, to describe only one of these mechanisms in detail. Each addressing mechanism includes an ink printing or impression roll I'I8` which is provided with ink by suitable inking mechanism. The printing roll IIB. is located above the stencil track and journalled in the. forward end portions of armsf|20i forming a part' of aframe |22 pivotally supported by a shaft |24'.

carried by a bracket |25. Each roll ||8. is provided with a cooperating platen |26 which is` located beneath the web 64 at the forwardk ends of arms |28 pivoted at |29 to the bracket |25; The platen is reciprocated toward and away from the stencil tracks by means including a lever |30 which is pivoted on a shaft |32 carried by the `bracket |25 and has an upwardly directed extension providedv with a cam face |34V which is adapted to engage a cam roller |35 of and` to raise and lower the platen. The lever |30 is connected by apivoted link |36 with a downwardly extending arm |38 of the printing roll supporting frame so that the reciprocation of the lever |30 causes the platen |26 and the roll I|8 to move toward and away from each other.

The lever |30 is reciprocated by an eccentric have been made thereon as there are sections in l the bill. For a three-section bill, as here shown, there will be three addressing operations.

As hereinbefore stated, the addressing mechanism I6 operates simultaneously with the addressing mechanism I 4. The addressing mechanism I6, however, prints the address of a stencil contained in a stencil track upon the back face of the web. The web is advanced following each addressing operation of the addressing mechanism I4 and passes through an invertingA or reversing mechanism |44 before the same section of the web reaches the address printing mechanism I6.

As shown most clearly in Figs. 2, 3, and 6, the web 64 passes beneath and through the addressing mechanism I4 and thence over a roll |46 and downwardly and under a web-inverting roll |48 which is mounted for rotation at an angle of substantially 45 to the path of movement of the web 84. The roll |48 is rotatably mounted inA bearing blocks |50 that are vertically adjustablel in an upstanding U-shaped bracket |52 which is suitably secured to the base I2 of the machine. The bracket |52 is provided with vertical slots |54 for receiving bolts |56 fixed to the bearing blocks |50. The paper web passes upwardly from the roll |48 over a guide roll |58 andthence between the web guide members |20. It is to be noted that the table I of the machine is cut away, as illustrated in Fig. 6, to receive a plate |60 to the-lower surface of which the rolls |46 andy |58 are rotatably mounted in suitable bearings. The paper web 64 is threaded under the roll |48 so that the bottom surface of the web 64 inv the downward pass of theweb is visible from the front of the machine. Thus in the upward pass of the web, the top surface of theweb is exposed to view and the top surface which .is exposed t0 view in the upward pass of the web is incontact with the guide roll |58 and thus the surfaces of the web are inverted or reversed by means of the reversing mechanism |44 andwhat was originally the bottom surface of theweb is.- now the upper surface which is to be exposed to the action of the addressing mechanism. I6;

The distance, measured along the length of the paper web, between the two addressing mechanisms I4 and I6 plus the loop formed by the reversing roll |48 is equal to three bill lengths, for the particular machine herein illustrated. The center line distance between the two addressing mechanisms I4 and I6 along the-stencil track is. equal to the length of three stencils.y Thus, when three addresses havebeen applied to the web 64 from one stencil that stencil is fed out of position below the addressing mechanism I4 andthe portion of the web which is addressed is moved step-by-step from below the addressing mechanism I4; The next successive stencil then has three addressing operations performed thereon and then that stencil is fed out of position below the addressing mechanism I4. 'I'hev same number of operations are performed on the next two succeeding stencils. The stencil which was first in addressing position below the addressing mechanism |4 has now been moved into addressing position below the addressing mechanismv I6. VAt the same time, of course, the web 64 has been fed forwardly and the web inverted' or reversed so that the portion of the web which received-the first address from the first stencil is located below the addressing mechanism I6. Thus, the addressing mechanism I6 will perform three addressing operations upon thebackface of the web 64 and then that stencil will beV fed out of addressing position and into the stencil. receiving holder II6, as hereinbefore described. By this means, the front and rear or top and bottom surfaces of the web 64 are provided with the same addresses which are in transverse alignment with each other and in the same bill section.

VSuccessive addressing operations are performed on successive stencils; and the web 64 af-ter having been addressed on both sides passes from the second addressing mechanism I6 to the scoringv mechanism I8. This mechanism includes an arm |62, Fig. 3, which is pivoted intermediate its ends to a bracket |64 fixed to the top surface of the table I0 and at its forward end carries a perforating or scoring knife |66. The rear end of the arm |62 is provided with a cam roll |68 which engages a cam disc |10 fixed to the shaft 48. The cam disc |10 has two notchesv I'II therein into which the cam roll falls to permit the arm |62 to be dropped to cause the perforating knife |66 to score the paper. The particular bill which is the product of the present invention is scored in two places and hence the scoring mechanism operates twice. on each bill, first to form the left hand scoring line D and second to form the right hand score line D. It` is apparent, however, that there can be as many notches in the cam disc |10 as there are linesof scoring for each bill and that the notches will be peripherally spaced in proportion to the lengths of the sections between the score lines.

The web is advanced from the scoring mechanism through the feed'converting mechanism 20*` andthence to the front printingv mechanism 22^ with the addresses. This front printing mechanism includes front printing impression and platen rolls |12, |14 which are mounted for conjoint rotation. The web is advanced continuously by the rolls |12 and |14 at such a rate that one bill length passes from the front printing mechanism and the addressing mechanism I6 at the same time. Since, however, the addrssing mechanism has reciprocating elements which necessitate the web being stationary at the times that the addressing operation is performed and since the sections B of each bill are or may be of unequal length the feed converting mechanism herein provided converts the continuous advance of the web 64 under the action of a front printing mechanism 22 into an intermittent advance by steps of suitable length so that the addresses and the printing data on all the bills will be in constant registration with each other.

The feed converting mechanism 28 is substantially the same as that described in detail in my above mentioned Letters Patent No. 1,985,- 247 to which reference may be made for a more detailed description of the construction and operation of this mechanism. The mechanism comprises, as shown diagrammatically in Fig. 3, a vertically reciprocating roll |16 located under the paper web which is held down on opposite sides of the roll by guide rolls 11, said feed converting roll is arranged to be Vmoved upwardly predetermined distances at predetermined intervals by a multi-lobed cam I 18 xed to the forward end of a substantially horizontal shaft4 |80 driven by miter gears |19 `from the shaft 48, the cam operating on the swinging frame I8 in which the roll |16 is rotatable. The cam |18 is provided with as many repetitions or lobes as there are address sections of the bill. Since the present machine is designed to make three section bills, the cam |18 is illustrated herein as provided with three lobes |82. The shape of the cam is such that the roll |16 is elevated so Vas to deflect the web 64 laterally of its length between the guide rolls |11 and to alter the length of the path of travel of the web and thereby to draw such amount of paper through the addressing mechanism which added to the amount advanced by the front bill mechanism 22 during such movements is the requisite amount of paper advance through the addressing mechanism for a bill section. The roll |16 is then dropped, leaving a loop of paper which the printing rolls must exhaust before they can advance the web in the addressing mechanisms. Thus, the web is stationary at times in the addressing mechanisms and during the operation thereof. The amount of draw or lift of each of the cam lobes |82 may be different for bill sections of different lengths and consequently may be so arranged that the roll |16 is operated to draw a greater amount of paper past the addressing mechanisms I4 and I6 for a long bill section than for a short bill section. Thus, while the front printing mechanism 22 operates to advance the web 84 through the printing mechanism in a continuous manner, the movement of the web is converted into an intermittent advance by a converting mechanism 20 so that the web is advanced past the addressing mechanism by steps which may vary in length depending uponvthe length of the bill sections and the web, of course, is held stationary momentarily to permit the adwhich prints the data E, Fig. 7, common to all thev bills on the .front .faces thereof in registration,v

dressing mechanisms I4 and I5 to perform vaddressing operations on successive bill sections.

- The addressing mechanisms .I4 and |'6 which as hereinbefore stated are substantially identical and are provided with inking mechanisms |86, Fig. 4, which are arranged to supply ink to the printing roll H8. The inking mechanisms |86 can be of any suitable Vtype and need not be further described herein except to state that each includes a roll driving shaft |88 whichV is common to both mechanisms and is drive Figs. 2 and 4,*through a belt |92 by the shaft |94, which shaft is driven by a belt from the continuously rotating shaft 30 of the power mechanism 28. The mechanism for supplying ink to front and rear printing mechanisms 22 and 24 is not describedV herein, since it is of substantially the same type as that disclosed in my above mentioned Letters Patent No. 1,985,247.

The front and back addressed and front printed web passes from the front printing mechanism to the back printing mechanism 24 Where it receives the printed data H, Fig. 8, common to all bills and herein common to the first two of the three sections of each bill but omitted from the last or office section. The back printing mechanism is similar to the front printing mechanism except that the positions of the impression and platen rolls are reversed, the impression roll being beneath the web. The rolls of both printing mechanisms have equal diameters and are driven at the same speed from the shaft 48.

After the web has passed through the front and rearprinting mechanisms 22 and 24 and has been completely printed and addressed, it passes through the severing mechanism 2B which operates inthe usual manner to sever the successive bills from the web 6:1, the reciprocating shearing lever |96 of the shearing mechanism being operated by the single lobe cam |98 of the shaft 48 once for each complete rotation of the shaft.

After the bills have been completely printed and addressed on both sides, and severed from the web as above described, the severed bills C are sent to the bookkeeping department where the various blanks on the face of the bill are filled in with data indicating, for example, the number of cubic feet or gallons of water used, the amount of the bill and the date which the bill is due. After the various item spaces have been filled in, the left hand section of the bill will be cut off along the line K-K. This portion which is substantially the same size as a Government postal card has a postage stamp L applied thereto and ismailed to the customer. The remaining two sections of the bill are filed away in the office until such time as the bill is paid or the due date of the bill has arrived. If,

on the due date, the bill has not been paid byY the customer, the remaining two sections of the bill will be severed along the line M-M and a stamp L will be applied to the central section and sent to the customer to remind him that the bill has not been paid. The right hand end or office section of the bill is then led away until the bill is paid or until the time arrives when the following months bilis are to be prepared and sent to the customer.

The narrow sections to the right of the score lines D of the left hand and central bill sections are intended to be severed from the body of the sections and presented as coupons with payment of the bill.V It' is apparent that the machine disclosed herein produces a multi-sectionbill which is arranged to facilitate bookkeeping procedure and to provide a method for ling the bills to provide a constant check upon the bills payable to ascertain whether 'or not all of the bills are paid upon the due date.
