My invention relates to improvements in laundry listing machines and has to do, more particularly, with an improved machine for printing a laundry list bearing the designations of the various classes of articles contained in a laundry bundle, and the number of articles in each class.

In modern laundry practice, it is desirable to provide a machine having a set of operating keys, one for each class of article likely to be found in a bundle of laundry, so that, as an operator goes through the bundle, she may operate the appropriate keys, once for each article of the class that she finds in the group of articles to be laundered. Having completed the setting up of the list by such operation of the required keys, and having placed a blank on the platen of the machine, the operator actuates the machine to print on the blank the name of each class of article found in the bundle and, opposite the name, the number of articles of the class.

The principal object of my invention is to provide an improved laundry listing machine of such construction that, although of equal or greater capacity than such machines heretofore known, it provides larger type for printing the number and names of articles, so that it produces a more legible laundry list.

A further object of my invention is to provide a machine of this class with larger key tips, the indications on which are more easily read.

Another object of my invention is to provide a laundry listing machine in which the printing members, for printing the names of classes of articles, are all normally at printing position, the printing members, corresponding to classes of articles not present in the laundry bundle, being automatically removed from printing position, just preceding the printing impression.

Still another object of my invention is to provide such a machine, in ywhich the eliminated printing members are retained out of printing position until the next resetting operation, preparatory to setting up a new" list, when they are automatically returned to printing position.

A further object of my invention is to provide a laundry listing machine having a resetting shaft, rotation of which restores displaced type wheels to normal positions, a printing shaft, rotation of which prints a list from the type of type wheels at printing position, and an interlock which prevents two succeeding resetting intervening printing operation.

Another object of my invention is to provide an improved laundry listing machine, in which 48 Claims. (Cl. 101-95) the numeral type wheels are driven by feed gears and the feed gears are selectively advanced stepby-step by operation of appropriate keys, to correspondingly advance the proper numeral type wheels.

Another object of my invention is to provide a laundry listing machine having improved means for correcting for erroneous key operation, the keys being pivoted and rocked, in one direction, to advance the corresponding type wheel one step, and, in the other direction, to return it one step.

A further object of my invention is to provide a laundry listing machine of such construction that, when a key has been operated, by error, to advance the corresponding numeral type Wheel from normal and prepare the selecting mechanism to leave the corresponding printing member at printing position in the printing operation, the error can be corrected easily by rocking the key in the opposite direction, which returns the type wheel to normal and returns the selecting mechanism to the condition in which the printing member will be moved out of printing position at the start of the printing operation.

A further object of my invention is to provide a laundry listing machine having means whereby the lot number, date and operators number may be printed at the top and bottom of the list.

Another object of my invention is to provide an improved laundry listing machine, which is simpler in construction and assembly than such machines heretofore known.

Still another object of my invention is to provide a machine of this class, which is more readily accessible for inspection or repair, due to the hinged keyboard frame that can be swung down carrying with it important portions of the settingup mechanism.

A further object of my invention is to provide an improved laundry listing machine having a signal light to indicate that the machine has been cleared properly, prepared to setting up a new list.

Another object of my invention is to provide such a machine with an improved impression mechanism, not dependent on the amount of pressure applied by the operator, so that clear and legible laundry lists will always be printed.

Another object of my invention is to provide a laundry listing machine having improved ribbon mechanism, and ribbon feed and reverse mechanism.

Further objects, and objects relating to details of construction and economies of operation, will appear from the detailed description to follow. In one instance, I have accomplished the objects of my invention by the devices and means described in the following specification. My invention is clearly dened and pointed out in the appended claims. A machine constituting a preferred embodiment of my invention is illustrated in the accompanying drawings, forming a part of this specification, in which:

In general, the laundry listing machine embodying my invention comprises a plurality of type wheels, selective means for rotatably advancing said wheels step by step from normal non-printing position, a plurality oi printing members normally in printing position, one for each of the type wheels, printing mechanism for making an imprint upon a blank from the type of type wheels and printing members at printing position, and automaticv means for moving away from` printing position the` printing. members corresponding to type wheels ln normal nonprinting position. The means for moving printing members away from printing position may be actuated by the printing mechanism. The machine may include a rotatable printer shaft, means for rotating the printer shaft, and means, actuated by rotation of the printer shaft, for moving away from printing position those printing members that correspond to type Wheels in normal non-printing position. There may be 'a cam fixed on the printer shaft which, upon rotation of said shaft, first acts to move away from printing position the printing members that correspond to type wheels in non-printing position and, then,` acts on the printing mechanism to make an imprint from the type wheels and the printing members remaining in printing position. The machine may be provided with a plurality of setting keys, one for each type wheel, so arranged that the corresponding type wheel is advanced one step each time its printing key is actuated. The setting keys may be arranged to actuate feed gears, one for each setting key, which feed gears are arranged to drive the cor-responding type wheels. For instance, I may provide a plurality of rotatable toothed type wheels, certain of the teeth of which bear numeral type consecutively arranged, and a feed gear for each type wheel, which meshes therewith and is arranged to be actuated by the corresponding setting key, so as t0 advance the feed gear one step each time the key is actuated.

My invention comprises a machine in which the printing members are carried by pivoted printing arms, that are acted on by means tending to retain the arms in printing position, devices being provided for automatically noi/ing away from printing position the printing arms that correspond to type wheels in non-pi' ff position. Each printing arm may be with a selector member, which remains in selecting position so long as the corresponding type wheel is in normal non-printing position, but moves to non-selecting position when the corresponding type wheel is displaced from the nonprinting position, and automatic means i'or moving away from printing position the printing arms whose selector members are in selecting position. The positions of the selector r obers may be controlled by the corresponding feed gears, as, for instance, by means oi a stud on the feed gear engaging a finger oi the selector member and holding it in selecting position, so long as the feed gear is in normal position, the movement of the feed gear from normal position permitting the stud to move away from the nger so that the selector member is allowed to move to the non-selecting position. For example, I may provide a rock shaft havingv a pick-up ledge thereon, so that, when the shait is rocked the ledge will enga-ge the selector members in selecting position and move them to rock the corresponding printing arms and carry their printing members away from printing position. This ,rock shaft may be rocked from one position to the other by toggle mechanism, actuated rotation of the printer shaft, to move the rock shaft from its normal to its selecting position, in which position it is retained by the toggle mechanism until returned when the toggle mechanism is restored to its previous position, upon the first operation of the resetting shaft following such4 printing operation. This resetting shaft provides means whereby, upon rotation thereof, all the feed gears and type wheels wiil be restored to their normal positions. The machine may be provided with an interlock of such nature that two successive operations of the resetting shaft cannot be performed without an intervening: printing operation. This interlock may take the form of a pawl, carried by the rocker member of the toggle mechanism and cooperating with a notch in a flange fixed to the resetting shaft. When the rocker member is in its normal nonselecting position, and the resetting shaft is in its normal position, this pawl will engage the notch to prevent rotation of the resetting shaft, but the operation of the printing mechanism will move the rocker member away from its normal position, so as to remove the pawl from engagement with said notch and permit the operation of the resetting shaft.

One novel feature of my invention consists in the setting keys that are pivoted to rock in two directions, and which are so connected to the if type wheels that a rocking of a key in one direction Will advance the corresponding type wheel one step, while the rocking of the key in the other direction will return the type wheel one step.

This affords a convenient means for correcting i.

erroneous depression of the keys. Each setting key is provided with a cam member for ace tuating the corresponding advance and return mechanism. In the case of the keys of one bank or row, `the cam members are integral with the 1 key stems, While, in the case of the remaining banks or rows of keys, the cam members are connected by links to the pivoted key stems. .All the cam members are coaxially arranged on a common shaft, which also constitutes the pivot r.

for the upper row of keys. Each cam member may be interposed between the operating arms of a corresponding pair of bell cranks, each of which bell cranks has a pawl-carrying arm on which a pawl is pivoted, one of these pawls being engageable with the corresponding feed gear to advance it one step, when the corresponding cam member is rocked in one direction, and the other pawl being engageable with the feed gear to return it one step, when the corresponding cam member is rocked in the other direction.

The setting keys may all be mounted in a keyboard frame, which is pivotally mounted on the main frame of the machine, so that it may be swung down to a horizontal position, in which access may be had to the feed gears and type wheels for purposes of adjustment or repair. This keyboard frame may carry the shafts on which the keys are pivoted, and also the shaft on which the bell cranks actuated by these keys are located.

The machine may be provided with a signal light, which is lit by the rotation of the resetting shaft to the end of its forward stroke, so as to show the operator that the resetting operation has been correctly performed. This signal light may be connected in an electric circuit with a normally open switch, which is closed by a part carried by the resetting shaft, when that resetM ting shaft has been turned to the limit of movement in one direction.

Referring to the numbered parts of the drawings, I have illustrated a laundry listing machine comprising a pair of side frames connected together, at the bottom, by the transverse bars 2| and, near the top center, by the transverse shaft 22, and near the front lower portion of the keyboard, by the transverse shaft 23. A casing 24 is applied to the side frames and covers the back and front of the machine, extending from a point near the rear cross bar 2| to the upper front of the machine, at the upper edge of the keyboard. T'he keyboard frame 25 is mounted between the front portions of the side frames 29, being pivoted on the transverse shaft 23 carried by said side frames. 'I'he keyboard frame 25 has the rearwardly directed flanges 26, at the sides thereof.

Keyboard frame 25, pivoted on the transverse shaft 23, is releasably held in the position shown in Figs. 2 and 3, but may be quickly and easily released so that it may be swung about the shaft 23 to the horizontal position, indicated by dotted lines in Fig. 9, in which position ready access may be had to the interior of the machine for purposes of repair or maintenance. Referring to Fig. 4, a hole 21 is formed in each side flange 26 of the keyboard frame, near the upper. end thereof. A bushing 28 is mounted in a hole in each side frame 20 and this bushing protrudes into a notch 33, that is milled out in the adjacent flange 26 of the keyboard frame. A plunger 29, having a pointed end, is slidably mounted in the bushing 28 and a spring 30 is interposed between a shoulder on the plunger 29 and a shoulder 3| formed in the bushing 28, so that the spring tends to project the plunger 29 into the hole 21 of the keyboard frame flange, to lock the keyboard frame in operative position. A knurled head 32 is fast on the outer end of the plunger 29 and the plunger may be withdrawn from locking position, against the pressure of spring 30, by means of said knurled head. When the keyboard frame is swung to the operative position, with the plungers 29 held withdrawn, the protruding ends of the bushings 28 engage the Walls of the milled out notches 33 and limit the inward movement of the upper end of the keyboard frame, at the same time locating the holes 21 opposite the ends of the plungers 29, which can then be released and allowed to snap under spring pressure into the holes 21 to lock the keyboard frame 25 in place.

Mounted on the keyboard frame 25 are sixty operating keys 34', arranged in six rows of ten keys each. One of these keys 34 is assigned to each of the classifications of articles likely to be met with in a bundle of laundry. For instance, one of the keys 34 is assigned to shirts, another to socks, one to tablecloths, another to pajama tops, another to pajama pants, one to bedspreads, another to pillow cases, another to sheets, and so on. It will be noted that these sixty keys 34, arranged in six rows, are in staggered relation to each other, so as to give room for the operating connections. Each key 34 will bear on the key top a legend indicating the class of article to which it is assigned. The con struction of the machine is such that these key tops may be made relatively large, so as to aford room for a legend printed in characters sufficiently large to be readily legible by the operator. Fixed'parallel horizontal shafts 35 are provided, one for each row of keys 34, the ends of said shafts being anchored in the side anges 26 of the keyboard frame. Keys 34 of the upper row have stems 38 pivoted on the upper shaft 35, and the keys 34 of the remaining rows have stems 31 pivoted on the shafts 35 provided for those rows of keys. Each of the keystems 38 of the upper row of keys has integral therewith a cam extension 39, extending rearwardly from the shaft 35. Interspersed between the cam extensions 39, on the upper shaft 35, are fifty cam members 40. one foreach of the keys 34 in the 7 remaining rows of keys. Each cam member` 40 has a forwardly extending neck 4l, to which the upper end of a link 43 is pivotally connected by a pin 42. The lower end of each link 43 is worked, as at 44, and straddles the stem 31 of the key to which it is assigned, being pivotally connected thereto by a pin 45. The key Stems 38 and 31 extend forwardly from the pivot shafts 35 through slots 36 provided in the keyboard` frame 25. It will be notedA thatl each of the key Stems 38 and 31 may be rocked either clockwise or counterclockwise about its pivot shaft 35'. The corresponding cam member 4B', or' cam extension 39, will be rocked clockwise or counterclockwlse about the upper pivot shaft 3,5,v depending upon i the direction in which the corresponding key stem is swung.

A shaft Si: is carried by the rearwardly directed iianges 26 of the keyboard frame, extending from one of these flanges to the other, and forms the support for the mechanism for advancing and returning the type wheels, as the several keys 34 are rocked in one directiony or the other. Sixty of these mechanisms are provided, one. for

each of the keys 34. Each of these mechanisms includes a pair of bell cranks 5i and 52, pivotally mounted on the shaft 5t, said. bell cranks having the forwardly extending arms 53 and 511., betwe which the corresponding cam member di), or ce extension 39, is interposed, shown inlitige. 2 and 3. A spring 55 has its ends connected to the arms 53 and 54 and tends to: rock the bell crank 5l clockwise, and the lower` b crank 52 counterclockwise, about shaft 5c, so as-to hold the arms 53 and 54 in engagement with the member d, or cam extension 39. Bell crank 5i has a pawl-carrying arm, on which a feed pavl 1 is pivoted at 55. Bell crank 52 a p carrying arm extending downwardly. tor which return pawl 59r is pivotally connected at 53. The ends of spring el] are connected, one to the pawl 51 and the other to the pawl 59, and this spring tends to rock the pawls toward each other until they engage the stop shoulders 5l andv 52 provided on the bell cranksv 5! and 52, respectively.

horizontal resetting shaft 4s is rotatably mounted on the side frames 2li of the machine. Journaled on the resetting shaft 4f; there are sirty feed gears 41, one for each of the keys 3e.

.ach feed gear 41 has a laterally projecting stud 4B and another laterally projecting stud 49 (-see Figs. 3 and 5). Each feed gear 41 is in line with the corresponding feed pawl 51 and return pawl arranged to be actuated by the key Eli that corresponds to the feed gear, and when the key 34 is rocked clockwise the correspondingcam extension 38, er cam member 43, willi likewise be rocked clockwise, the corresponding bell crank 5l will be rocked counterclockwise. and the-pawl 51 carried thereby will be caused to engage a tooth of the corresponding feed gear 41 and ad vance that feed gear one step. However, if a key 34 be rocked counterclockwise about its pivot on shaft 35, the corresponding cam extension 39, or cam member lill,v will likewise be rockedl counterclockwise, and this will rock the corresponding bell crank 52 clockwise, causing the pawl 59 carried thereby to engage the corresponding feed gear 41 and move that gear one step in the reverse direction, that is, return Said one step. Thus, if a key has been actuated erroneously, advancing its feed gear 41 one step when it should not be advanced, the error can be corrected by rocking the key 34 counterclockwise to return said feed gear 41 one step.

There is a detent spring BI for each of the gears 41, engaging the periphery thereof. These detent springs 6l are mounted on a transverse shaft d2, the ends of which are mounted in adjusting brackets 03, pivoted at G4 on the side frame members 25. Each bracket has an elongated slot 65 receiving an eccentric portion 66 on an adjusting screw 61 (see Fig. 11). By turning the screw 61 the adjusting bracket 63 is rocked on its pivot 64 to raise or lower the corresponding end'oi shaft 52. In this way, the detent springs el may be adjusted so as to make proper contact with the space between teeth ol the gears 41. These detent springs 6i serve as aligning means for the i'eed gears 41.

Mounted on the shaft B, which extends transversely of the machine between the side frame members 2B, there are sixty type wheels Gil, one for each of the keys 34 of the keyboard. Each type wheel meshes with the corresponding feed gear 41. There are forty teeth in the gear 41 and forty teeth in the type wheel til. These type wheel teeth, beginning with the tooth 16 and running counterclockwise, have type for printing the numerals 1, 2, etc., up to an including 37. The teeth numbered 1i do not have any type thereon and are blank, ano., when type wheel is positioned so that tooth "il is at the printing line, no numeral printing will result and the type wheel is in its normal, nonprinting postion. The teeth numbered 1l are also blank` having no type thereon. When one oi the keys 34 is operated by rocking it clockwise about its pivot, the corresponding feed pawl 51 will engage and advance the corresponding feed gear 41 one step, which also advances the corresponding type wheel $59 one step. Thus, if the key 34 representing shirts is depressed, the corresponding type wheel 69 will be moved from the blank or nonprinting position to present the numeral type l at the printing line. If that key isv depressed a. second time, the type wheel will be advanced a second step to present the numeral 2, and so on. If the key is depressed in error, a correotion may be effected by rocking the key counterclockwise, which moves the feed gear d1 and the corresponding type wheel 69 one step in the reverse direction, to correct for the error.

Journaled on a transverse shaft 12, which extends between the two side members 20 of the frame, are sixty printing arms 13, one` for each of the keys Each printing arm has a rearwardly-extending ear 14, a cam notch 15 near the lower end thereof, and a foot 16. A printing plate 11 (see Figs. l2 and 13), of channel-shaped formation, and having type on the lowerl surface thereof for printing the name of the class of article to which the corresponding key is assigned, is detachably mounted on the foot 16 of each printing arm. The printing plate has notches 18 in the side walls thereof, which receive a pin 19 on the foot of the printing arm, and there are cam notches 3Q at therear of the printing plate. which are engaged by a spring 8| fastened in a slot 82 in the lower end, of the printing arm. This provides means whereby the printing plate can readily be removed. from the printing arm.

One end of a spring 851i is connected to the upper end of each printing arm 13, above the pivot shaft 12 thereof, and the other ends of the springs 89 are connected to a spring bar 90 carried by and extending between the side members 20 of the frame. These springs 89 tend. to swing the printing arms 13 to printing position,` in which the printing plates 11 are in position to print the names of the classes of articles assigned thereto. The printing position of the printing arm 13 is determined by the engagement of the notch 15 with a transverse rod 83, the ends of which are mounted in arms 84, pivoted on the shaft 68 near the side members of the frame. Each arm 84 has an oblong slot 85 formed therein, which receives the eccentric portion 84h of an adjusting screw 84a (Fig. '1) journaled in a boss 86 on. the adjacent side member 20 of the frame. By turning this adjusting screw, the arm 84 may be adjusted angularly about shaft 68, so that the corresponding end of rod 83 may be accurately positioned to bring the printing plates 11 to the proper printing line. A comb 81 extends forwardly and upwardly from the rod 83 and is provided with slots, one for each of the printing arms 13, in which said arms work. This comb keeps the printing` arms properly spaced. A housing 88, formed of sheet metal, is carried by the side members 20 of the frame and extends across the lower front portion of the machine opposite the positions occupied by the lower ends of the printing arms. When these printing arms are moved to non-printing position, as Will be described later, they move back within this housing 88.

At the upper end of each printing arm 13, a selector member 9| is pivoted to the ear 14 of the printing arm, by the pin 92. This selector member has a rearwardly extending finger 93, normally lying in the path of the pin 49 on the corresponding feed gear 41. Each selector member 9| also has a forwardly extending finger 94 and an oblong slot 95, concentric with the pin 92 and receiving the shaft 12. A spring 96, mounted in the upper end of each printing arm 13 above the 'pivot shaft 12, engages the upper edge of the corresponding selector member 9| and tends to rock that selector member clockwise about its pivot pin 92. When a feed gear 41 is displaced from its normal non-printing position, the stud 49 is removed from the finger 93 of the corresponding selector member, and permits the spring 96 to rock that selector member clockwise, so as to move the forwardly-extending finger 94 out of the path of a pick-up ledge 91, attached to a rock shaft 98, which is journaled in the side members 20 of the frame. Two springs |00, one at each side of the machine, connected, at their upper ends, to the ends of the pick-up ledge 91 and, at their lower ends, to pins IOI carried by the side frame members 20, yieldinglyihold the pick-up ledge in' its normal non-selecting position, against the stop pins 99 carried by said side frame members 20. When the rock shaft 98 is rocked clockwise, by means to be described hereinafter, against the tension of springs |00, the pick-up ledge 91 engages the fingers 94 of all se- -lector members 9| that are in selecting position,

that is to say, those selector members which are held in the position, shown in full lines in Fig. 3, bythe engagement of the studs 49 on their feed gears 41 with the ngers 93 of the selector members. In the case of feed gears 41 that have been displaced from the normal position, the springs 96 have rocked the selector members 9| clockwise to carry the fingers 94 out of the path of the pickup ledge 91. When the rock shaft 98 is rocked clockwise, the pick-up ledge 91 engages the fingers 94 of the selector members in selecting position, and rocks them counterclockwise. Since the bottom of the slot 95, of a'member in selecting position, engages the 12,it` acts l0 as a fulcrum and the corresponding printing arm 13 is rocked counterclockwise to remove the printing plate 11 from printing position.

A shaft |02 is fixed in the side members 20 of the frame and extends transversely of the machine. A pair of platen-operating levers is journaled on the shaft |02, each lever having an upwardly and rearwardly extending operating arm |93 and a forwardly and downwardly extending platen-carrying arm |04. Springs |05, anchored at their rear ends to the side members 20 of the frame and secured at their forward ends to the arms |03, tend to rock the levers, of which arms |03 form a part, counterclockwise and thus tend to counterbalance the weight of the platen and associated parts. A base |06 is carried by the forwardly-extending arms |04 of these two levers, `the base having downwardly-extending ears |01, at the ends thereof, which ears are pivoted on pins |08 carried by the arms 04. A platen |09, which may be of rubber or like resilient material, is carried by the base |05, to which there is also secured a sheet metal platen extension |I0 extending forwardly therefrom. A bar is adiustably mounted on this extension and serves as a guide or abutment, against which the righthand edge of the blank or form is placed to position it properly on the platen for printing the numbers and names of the articles in the proper place on the laundry list. Each arm |04 of the platen-operating levers has bearings ||2, in which adjusting screws ||3 are mounted, said adjusting screws bearing against bosses. I I4 on the bottom of the base |06. By adjustment of the screws ||3, this base may be titled one way or the other about the axis of pins |08, to bring `the platen |09 to the proper level to get a good impression. The upper end of each arm |03 is forked and carries a follower roller H5, which engages a cam ||1 fast on a shaft I|6 journaled in the side members 20 of the frame, and having an operating crank IIB fast thereto, on the lefthand side of the machine. When the shaft ||6 is given a revolution counterclockwise by turning the crank IIB, the high spots of cams ||1 engage rollers |I5 and rock the platen-operating levers counterclockwise, bringing the blank supported on platen |09 vagainst the inking ribbon, which is interposed between it and the type wheels 69 and printing plates 11 at printing position, so as to make an imprint on the blank supported on the platen |09. When the high spots of cams ||1 pass out from under the rollers H5, the weight of the platen and its associated parts returns them tothe normal position, shown in Fig. 3.

The cams II1 also act on the follower rolle-rs |I1a of the selecting mechanism for the printing arms, as best shown in Fig. 2. At each side of the machine, there is a toggle mechanism including a rocker member |I9, pivoted on a stud |20 carried by the adjacent side member 20 of the frame. This rocker member I|9 has a forwardly and upwardly extending arm |2I, from which extends a pin ||2. A spring |35 is mounted on the pin |22 and abuts against a shoulder |23 at the junction of the pin |22 and the arm I2I. The other end of spring |35 engages a block |24 that is slidable on the pin |22, and

which has laterally-extending trunnions |25, re-

ceived in notches |26 in the forked end |21 of an arm |28, journaled on the shaft 12 and Drovided with a cam |29. Each cam |29 is adapted to engage a follower roller |30, carried by an arm |3I fastened on one end of the rock shaft 98, to which the pick-up ledge 91 is fixed. When the parts occupy the position shown in Fig. 2, and the shaft ||6 is given a revolution, cams ||1 will engage the follower rollers ||1a and rock the rocker members I I9 clockwise about the studs |20. This causes the trunnions on the blocks |24, due to their engagement in the notches |26, to rock the arms |23 and cams |28 counterclockwise about the aXis o-f shaft 12. Springs are compressed until dead center is passed, when they will again expand holding the parts in the moved position, until force is aD- plied to rock the rocker members I9 counterclockwise. The counterclockwise rocking of the cams |29, due to their engagement with the follower rollers |30, will rock shaft 98 clockwise against the tension of springs |90, thus causing the pick-up ledge 91 to engage the fingers 94 of selector members 9| in selecting position and rock the corresponding printing arms 13 to carry them and their printing plates 11 away from printing position. It will be apparent, from Fig. 3, that the high spots of cams |1 act on the follower rollers lla before they act on the follower rollers ||5 and thus, before the printing operation takes place, the rotation of the printer shaft ||6 will result in automatically moving away from printing position the printing plates that correspond to feed gears 41 and type wheels 69 that have not been displaced from normal nonprinting position. These fed gears and type wheels are those that correspond to keys 34 that have not been actuated since the last resetting operation.

Referring to Figs. 2 and 3, a transversely extending locking rod |32 extends between and is carried by the rocker members H9 and, when these rocker members are swung to the selecting position to actuate the rock shaft 98 and move selected printing arms from printing position, locking rod |32 will be swung into the space between teeth of the gears 41 and lock these gears and the type wheels against movement during the printing operation. Each rocker member ||9 also has a laterally-extending ange |34, which cooperates with certain parts that will be described in connection with the resetting mechanism.

The operator may print as many lists as he desires from a given set-up, but it will be necessary to reset the mechanism to normal before setting up for the printing of a different list, representing the contents of a different bundle. This may be accomplished by rotating the resetting crank |36 at the right-hand side of the machine. Referring to Fig. 5, this crank is carried by a hub |31 fast to a pinion |38, which is journaled on a stud |39 carried by the right-hand side mem berA 20 of the frame. Pinion |38 meshes with a pinion |40 having an equal number of teeth, which has a hub |42 jo-urnaled in a bearing |4| carried by the right-hand side frame member 20. The hub |42 is keyed by spline |43 to a member |44, which is fastened by a screw to a companion member |46 mounted on the end of shaft 46 and fastened thereto by a set screw |41. Thus, rotation of the resetting crank |36 rotates pinion |36 in one direction, and pinion |40 in the opposite direction, which motion of pinion |40 is transmitted through members |44 and |46 to the shaft 46. Referring to Fig. 5, it will be seen that the left-hand end of the resetting shaft 46 is mounted in the left-hand side frame member 20 in substantially the same manner described with reference to the right-hand end of the shaft. A sleeve |65 is journaled in a bearing. |41 Qarried by the left-hand frame member 20. A member |44 is mounted on the sleeve |65 and fastened thereto by a spline |43. A companion member |46 is secured to member |44 by a screw |45 and member |46 is fastened to the left-hand end of shaft 46 byy a set screw |41. Referring to Fig. 5, sixty resetting discs |48, one for each of the gears 41, are mounted on the resetting shaft 46. Each resetting disc is keyed to the shaft 46 by a key |50 (Fig. 3). Each of these resetting discs |48 has a projection |49, which normally lies in front of thestud 48 on the corresponding gear 41. The operator, by means of a crank |36, rotates shaft 46 to the limit of movement in the clockwise direction (Fig. 3), which causes the projections |49 on the resetting discs to engage the rear sides of pins 48 and bring all the pins to the normal position shown in Fig. 3. The operator then reverses the direction of rotation of crank |36 and returns that crank and the resetting discs to the normal positions shown in Fig. 3, in which the projections |49 lie in front of the pins 48.

Each of the members |44 has a ange |5| thereon, in which a notch |52 is formed. When the resetting shaft 46 and members |44 are in their normal positions (Fig. 3), and the rocker members ||9 are operated by the cams ||1 to select the printing plates and take an imprint, the flanges |34 move into the notches |52 and against the front walls of those notches, as shown in dotted lines in Fig. 2. Just as soon as the re setting shaft 46 is turned in the clockwise direction, at the beginning of the resetting operation, the front walls of notches |52 engage flanges |34 and rock the members ||9 counterclockwisa thus moving the toggles to the normal position shown in Fig. 2. This causes the cams |29 to move away from the follower rollers |30, so that springs |00 can rock the shaft 98 and the pick-up ledge 91 to the position shown in Fig. 2, in which position springs |00 maintain the ledge 91 against the stop pins 99. Each member |44 has integral therewith a radially-extending finger |53, which liesl against the stop |54 when the resetting shaft 46 is in normal position. At the end of the first half of the resetting stroke, these lingers lie above the stops |54, which limit the movement of the shaft 46 in that direction, and at the completion of the resetting stroke, when the parts are in the position shown in Fig. 2, the ngers |53 lie beneath the studs |54.

Each flange I5| has a peripheral notch |55, which, as shown in Fig. 2, is located just in iront of the notch |52. A pawl |55 is carried by eachiockei member |I9, being pivoted on the pin |20. 'and each 'of these pawls is held against a stop pin, |51 by a 'spring |58 connected, at one end, 1p the pawl |56 and, at the other end, to the corresponding rocker member H9. It will be seen that, with the parts in the position indicated in Fig. 2, the engagement of the pawls |56 in the notches |55 prevents the rotation of the members |44 and the resetting shaft 46 clockwise, as is required for the initiation of a resetting operation. The parts are shown in Fig. 2 in the position they occupy at the end of a resetting operation and, because of the coaction of the pawls |56 with the notches |55, a second resetting operation cannot be performed without an intervening printing operation. When the printer shaft I I6 is rotated by means of the crank ||8, the rocker members ||9 will be rocked clockwise and will remain in. the position to which they are rocked until the next resetting operation This movement of the rocker members ||8 clockwise carries the pawls |56 out of the notches |55, so that the resetting shaft 46 may be rotated clockwise-in a resetting operation. At the beginning of this resetting operation the rocker members ||9 will be rocked counterclockwise to the position shown in Fig. 2, and this causes the pawls |56 to engage the peripheries of the flanges on which they ride until the close of the resetting operation when springs |58 cause the pawls |56 to snap into the notches |55 and thus lock the resetting shaft 46 against clockwise movement until the pawls |56 are removed in a subsequent printing operation.

The manner in which the resetting shaft 46 is mounted in the side members of the frame is shown in Fig. 5. Shaft 46 is provided, at each end thereof, with an axially-extending bore |59, the inner portion of which is of reduced diameter forming a shoulder |60. A portion of the bore |59 is internally threaded, as indicated at |6|.

A stud |62 extends through the hub |42 of gear |40, at the right side of the machine, and a similar stud |62 extends through the sleeve |65 at the left side of the machine. Each of these studs has an externally-threaded portion |63, screwing into the internally-threaded portion 6| of the corresponding bore |59, and each stud also has a pilot portion |64, which extends into the portion of the bore |59 of reduced diameter. This forms a very convenient means for assembling and disassembling the resetting shaft 46, with the gears 41 and resetting discs |48 mounted thereon. By removing the studs |62 and the screws |45, the entire unit, including members |46, may be quickly and easily removed from the machine and this unit may be conveniently replaced in the machine and mounted therein by replacing the screws and the studs |62.

A similar arrangement is used for mounting the type wheel shaft 68, as shown in Fig. '7. The side frame member 20 has a boss |66 provided with a bore therein, through which stud |69 extends. Shaft 68 has an axially-extending bore |61 having an inner portion of reduced diameter forming a shoulder |68. Stud |69 is externally threaded at |10 to screw into an internally-threaded portion of bore |61, and stud |69 has a pilot portion |1| of reduced diameter tting in the portion of the bore |61 of smaller diameter. The other end of shaft 68 is mounted in the same manner.

Referring to Fig. 2, hubs |12 are journaled on studs |13, carried by the side members 20 of the frame in line with the axis of shaft i 52. The legs |14 of a bail |15, which extends across the platen extension ||0, are fixed in the hubs |12. This bail may be made of a translucent plastic material having marks thereon to permit the operator to align the form properly on the platen |09 and platen extension ||0. Springs |16 areconnected, at their upper ends, to the hubs |12 and, at their lower ends, to pins |16' on the side frame members 20, and tend to rock the bail |15 so as to carry it against the form mounted on the platen.

It is desirable to provide a signal to indicate to the operator that a complete stroke of the resetting crank |36 has been given in one direction, before reversing the movement of the crank, and also for the purpose of indicating to the operator if the movement of the operating crank has not been reversed to restore the parts to normal position. For this purpose an electric lamp |11 (Fig. 1) is providedon the right-hand side frame member 20, near the lower front corner of the machine. Referringto Fig. 14, .the electric lamp |11 has terminals |18 and |19, one of which is connected by a lead to one side of the power line. The other terminalis connected by a lead ISI to one terminal |82 of a normally-open microswitch |83, the other terminal |84 of which is connected by the lead |85 to the other side of the power line. It is necessary to close the normallyopen microswitch |83 to light the lamp |11. Referring to Fig. 6, the microswitch |83 has an operating button |86 and, at the completion of the forward portion of the resetting stroke, the finger |53 will lie above the stud |54 and contact the operating button |86 to close the microswitch. If the operator completes the forward stroke to the limit of movement in one direction, the microswitch will be closed and the lamp lit, but, if he fails to complete the forward stroke, the light will not come on and he will know that he has to complete the stroke. Just as soon as finger |53 is moved away from stud |54, at the beginning of the return stroke of the resetting crank |36, the microswitch |83 will open automatically and the light will go off. The microswitch |83 is pivoted on a stud |81 carried by the right-hand side frame member 20. A plate |88 is fastened to the side of the microswitch and provided with a slot |89, in which the eccentric portion |90 of an adjusting screw plays. This adjusting screw is mounted in the adjacent side frame member 20, with its eccentric portion in this slot. By turning the screw the microswitch can be tilted slightly on the pivot |81, to adjust the contact between the operating button |86 and the end of finger |53.

Fig. 15 of the drawings is a view of a typical laundry list printed on this machine. The machine prints on the blank, placed on the platen |09 and the platen extension ||0, with its righthand edge resting against the bar I, the means of the various classes of articles in the bundle and to be included in the list, as indicated at F, from the printing plates 11 that are at printing position at the time of the printing operation. The machine also prints on the blank, as indicated at G, opposite each name, the number of articles of that classification contained in the bundle and included in the list, this printing being made from the type wheels 69. The machine is also arranged to print, at both the top and the bottom of the list, the lot number indicated at A, the month, day and year of the date, as indicated at B, C and D, and the operators number, as indicated at E. In order to print the lot number A, the month, day and year, B, C, and D, and the operators number E, at both the top and bottom of the laundry list, as shown in Fig. 15, two type wheel assemblies are provided, one on the lower front corner of each side frame member 20. Referring to Fig. 9, the side frame member 20 has a horizontal surface |9| formed therein, and a vertical surface |92 at right angles thereto, and the side frame member then continues horizontally toward the rear in the surface |93. A finished surface |94 and a boss |95 are provided on the side frame member for the attachment of parts of this type assembly, said boss being provided with a horizontal keyway. The side frame member is also provided with a laterally extending flange |96. A bearing member |91 is secured to the surface 94 and boss |95 by screws |98, and this bearing member has a bearing |99, in which fits the pilot portion 20|', of reduced diameter, of a shaft 200, on which the type wheels 204 are assembled. Shaft 200 has a collar 202 of large 75 diameter, adjacent the outer end thereof, and a forward portion 203, of smaller diameter. A series of type Wheels 204 are rotatably mounted on the shaft 200, the rearmost of these type wheels engaging a collar 205 pinned to the sha-it. The type wheels are arranged in pairs and Spacing collars 20S are interposedrbetween the pairs. The foremost type wheel abuts against the collar 202 on shaft 200. At each type wheel position, the shaft 200 is provided with a radial socket 201 (Fig. 7), in which works a ball 208 pressed outwardly by a spring 209, and each type wheel 204 has a series ofV internal notches 2|0, one for each type position, whichv notches are adapted to be engaged by the ball 208 to yieldingly hold. the type wheel in alignment in an adjusted position. Each type wheel has on its periphery ten type, for printing the numerals 1 to 9, inclusive, and 0, an eleventh type, which may be reserved for printing a special mark, and a blank nonprinting position, having no type on its periphery at that point, Each type wheel, therefore, has twelve positions and there are twelve of the internal notches 2 I 0.

A. rod 2H, which serves as a ribbon guide, has its rear end mountedl in the socket 212 in the bearing member |97, and its lforward end is mounted .in a hole 2. i 3 in the corner ci the plate 2 i fi, which also fits on the reduced portion 203 oi shaft A pin 2i5, mounted in the portion 22 ci the side trame member 20. extends forwardly through a hole 2i6 in the plate 2M, and has reduced neck portion 21,1. A knob Ei is mounted on the forward end of shaft 200 and held thereon by nut 2|9 (Fig. 1). The hub 220 of this knob 258 has iiat sides 22|, which nt anr irreguiar opening in a hook member 223l having a notch 224 concentric with the axis of shaft 200, and which may be swung to engage the reduced portion 2|? of pin 2|5, as shown in Fig. 10. Plate 2id is held in predetermined position with reference to shaft 200 by means of a pin 225, carried by said plate 2|4 and extending into a groove 225 in the side of the collar 202 on shaft 2Gb. swinging the hook 223 counterclockwise, the shaft 2ll0 and the type wheel assembly carried thereby may be quickly and easily removed from the machine. The operator may adjust each of the type wheels individually to position to print the desired lot number, date and operator number. Having thus positioned the type wheels, the entire assembly can be easily returned to place and locked in position by swinging the hook 22S clockwise to the position shown in Fig. 1G.

Referring to Fig. 2, the member |91 has a laterally-extending ear 221 provided with a socket 229, in which the rear end of shaft 223 is seated. This is the shaft on which the ribbon spool is mounted and the shaft is fastened in place in socket 229 by pin 230 (Fig. 16). -Journaled on shaft 228 in front of member |91 is the hub 23| of a bell crank lever having al pawl arm 232 and a laterally-extending operating arm '233 (Fig. '7). Journaled on the shaft 228 (Fig. 16) in front of this hub is a ratchet wheel 234 integral with the rear iiange 235. rEhe ribbon spool 23S icurnaled on shaft 228 and provided with slots 231 which receive pins 238 extending forwardly from flange 235. .A flange 239 is mounted on shaft 228 in engagement with the forward end of ribbon spool 236 and this front `flange has an integral knob portion 242, with a knurled periphery. This knob portion has a countersunk recess 24I. The knurled head 242 of a screw 243, which is screwed into an internally-threaded socket in the end of shaft 228. has a flange engaging in the outer portion of the countersunk recess 24|, and a spring 244 is interposed between the bottom of that recess and head 242, being fried to the latter so as to be removable with the head and the screw. This spring exerts a braking pressure to prevent too free turning of the spool on the shaft. The forward end of the spool is also provided with slots 231, like those at the rear end, and rearwardly-extending pins 238 are provided on ange 239 and engage in said slots. By turning the ilange- 239 by the knurled knob 240, the tension on the ribbon may be adjusted manually. To remove the ribbon spool, the screw 243 will be removed by means of the head 242 and the flange will then come oil' the shaft 22E, permitting one to easily remove the ribbon spool. @ne of these ribbon spools will be mounted in this way on each of the members |91 attached to the side members 20 of the machine frame.

The pawl arm 232 has a housing 245, in which a pawl 246 is slidable, said pawl being in position to engage the ratchet wheel 234. The upper portion of the pawl is reduced and extends through the top of the housing 245, a spring (not shown) being interposed between a shoulder on the pawl and the upper end of a recess in the housing and tending to project the pawl toward the ratchet wheel. The reduced upper end of the pawl has a cam 249, which bears on the upper end of housing 245, pivoted thereo by Dill 250, said cam having an operating handle 25|. By turning the handle 25| conuterclockwise (Fig. 2) cam 249 will bear on the upper end of housing 245 and withdraw pawl 246 from engagement with the teeth of the ratchet Wheel 234. The end of operating arm 233 is pivotally ccnnec ted to the upper end oi a link 253, the lower end of which is pivotally connected at 254 to an ear 255 on the arm |04 of the platen-operating lever at the corresponding side o the machine.

A similar ribbon spool mounting and ratchet operating mechanism will be provided on each of the two side frame members 20 of the machine. The direction of ribbon feed may be reversed by f moving pawl 246, at one side ci the machine, to

inoperative position and moving the corresponding pawl, at the other side of the machine, to 0perative position. Referring to Fig. l, the inking ribbon passes from the ribbon spool at one side of the machine, beneath the ribbon guide rod 2|i at that side of the machine, and thence horizontally to the other ribbon guide and ribbon spool., passing immediately beneath the sets of type wheels for printing the lot number, date and operators number and beneath the sets of type wheels 69 and printing plates 11 for printing the number of articles in a class and the names of the classes. Of course, the inking ribbon passes between these type wheels and the blank sup- GO ported on the platen |03.

The operation of the improved laundry listing machine embodying my invention should be quite apparent from the preceding description, but will be explained briefly at this point. It is assumed that the parts are in normal position as shown in Fig. 3, having been brought to that position by a preceding resetting operation. The operator places a blank upon the platen |09 and the platen extension ||0, with the right-hand edge of the blank in engagement with bar Bail |15 may be lifted, against the tension of spring |10, to permit the locating of the blank on the platen and, then, the bail is released and tends to hold the blank in position. The operator now goes through the bundle of laundry to be listed and, each time he flnds in that bundle an article of a certain classification, he actuates clockwise (Fig. 3) the key 34 corresponding to that classication. For each such actuation of a key 34, the corresponding feed gear 41 will be moved counterclockwise one step from normal, and the corresponding type wheel 69 will be moved one step from normal position in a clockwise direction, with the result that, when the operator has gone through the bundle and completed the setting up of the listing machine to print the list, the type wheels 69, corresponding to the keys 34 that have been actuated, will be in position to print the number of articles of each of said classifications found in the bundle. Whenever a feed gear 41 is displaced from the normal position, shown in Fig. 3, the movement of the Vstud 49 away from the linger 93 of the corresponding selector member 9| will permit the spring'96 to rock that selector member to non-selecting position, shown in dotted lines in Fig. 3. Consequently, at the end of the setting-up operation, those selector members 9| that correspond to keys that have not been actuated in said operation, will be in selecting position, and the selector members 9| corresponding to keys that have been actuated in the setting up operation will be in non-selecting position.

At the end of the resetting operation and during the setting-up operation, the printing arms 13 and the printing plates 11 carried thereby remain in the normal printing position, being yieldingly held in that position by the springs 69. To eiect a printing on the list supported by the platen |09, the operator gives a complete revolution counterclockwise to printer shaft ||6 by means of the crank IIB. The first effect of this rotation of shaft I|6 is to rock the rocker members ||9 clockwise about the studs |20. Through the toggle link connections this rocks the cam members |29 counterclockwise and these cam members, acting on the follower rollers |30, rock the shaft 98 clockwise, so that the pick-up ledge 91 engages the fingers 94 of those selector members in selecting position and, rocking them about the shaft 12 as a fulcrum, rocks the printing arms 13, corresponding to the selector members 9| in selecting position, out of printing position against the tension of springs 89, thus carrying the printing plates 11 on said arms 13 away from printing position, and leaving at printing position only those printing plates 11 that are carried by arms 13, which correspond to selector members 9| that were in non-selecting position. In other words, the first effect of the rotation of shaft I6 is to move away from printing position those printing members 11 that correspond to keys 34 that were not actuated during the preceding setting-up operation, leaving at printing position the printing members 11 that correspond to keys actuated during such operaation. As the shaft ||6 continues to operate, the platen-operating levers comprising the arms |04 and |03 are rocked counterclockwise so that the platen |09 carries the blank placed thereon against the type of type wheels 69 at the printing line, and against the printing plates 11 at printing position, so as to print on the blank the numbers of articles and names of the classes of articles found in the bundle listed. At the same time, the blank is carried against the type of type wheels 204 to print thereon the lot number, the date and the operators number.

If the operator actuates a key 34 erroneously, thus advancing a feed gear 41 and a type wheel I69 when they should not be advanced, this may be corrected for by actuating the key 34 counterclockwise, which will return the feed gear 41 and the type wheel 69 one step. If this one-step return or correction movement of feed gear 41 brings it to normal position, the stud 49 thereon will engage the nger 93 of the corresponding selector member Ql, and return that selector member to selecting position against the pressure of its spring 96.

The operator may print as many lists as desired from the same set-up, placing the blanks, one after the other, upon the platen |09 and rotating the printer shaft ||6 once for each impression. The selected printing plates 11 remain away from printing position, due to the character of the toggle linkages between the rocker members ||9 and the cam arms |29, which hold the pick-up ledge 91 in the selecting position from the time it is moved to that position by rotation of the shaft ||6 until the next resetting operation. When the operator desires to set up for printing a new laundry list, she must first perform a resetting operation by rotating the shaft 46 (Fig. 3) first clockwise and then counterclockwise, by means of the resetting crank |36. As has been described above, this causes the ngers |49 on the resetting discs |48 to engage the studs 48 of feed gears 41 that have been displaced from normal position, and return those feed gears to normal position, after which the resetting discs are rotated counterclockwise to the position shown in Fig. 3. rlhe first movement of the resetting shaft 46 clockwise causes the front walls of the notches |52 to engage the flanges |34 of the rocker members ||9, and rock said members counterclockwise to the normal position shown in Fig. 2, thus restoring the toggle linkages and the cam arms |29 to the normal positions and permitting springs |00 to return the pick-up ledge to its normal position. Thereupon, all printing arms 13 and printing plates 11 return to their normal printing positions. When the operator has turned shaft 46 to the full extent in the clockwise direction, during the forward part of the resetting stroke, the signal lamp |11 lights up to tell the operator that he has completed the resetting stroke in one direction. I1' he fails to turn the resetting crank |36 in the other direction, to return the parts to normal position, the lamp |11 will remain lighted, indicating that the machine has not been operated correctly to effect resetting. As has been described already, the notches |55 and the pawls |56 form an interlock that prevents two successive resetting operations without an intervening printing operation.

One advantage of the improved laundry listing machine shown herein is that, because of the use of the intermediate feed gears 41, which also serve the purpose of feed ratchet wheels, I can use much larger type for printing the number of articles and the names of the articles, and thus provide a machine that will print a more legible laundry list. Another advantage of the machine is that the construction is such that a larger keyboard may be provided, having larger keys with indicators thereon that are more easily read. The machine is of simple construction 'and assembly and the hinged keyboard construction is one which makes for easier maintenance and inspection, since the keyboard may be swung down to a horizontal position to permit access to the interior of the machine. Another advantage of this machine is the Divoted key conatsagiee struction, by means of which actuation of a key, in one direction, feeds the corresponding type wheel and actuation, in the other direction, reverses the direction of movement of the type wheel to correct for an erroneous operation. This correction is effective'v even though the corresponding selector member has been moved to position to select a printing member for movement away from printing position. Thus, a full correction of the set-up can be very veasily made. The printing impression is not dependent upon the amount of pressure applied by the operator and is uniform, due to the fact that a full revolution of` the printing cams forces the platen against the type. The machine also provides means for printing the lot number, the date and the operators number at both the top and bottom of the list. The type wheel assemlies for printing this data can be very quickly and easily removed and set to print the desired numbers. A simple and convenient ribbon spool mounting, and means for reversing the direction of ribbon feed, are also provided.

I am aware that the laundry listing machine shown herein may be varied considerably without departing from the spirit of my invention and, therefore, I claim my invention broadly, as indicated by the appended claims.
