3,145,890 STAMP DISPENSING MACHINE Homer K. Gordon and Andrew Morgan, both of 3725 Touzalin Ave., Lincoln, Nebr. Filed Nov. 29, 1960, Ser. No. 72,511 7 Claims. (Cl. '22516) This invention relates generally to improvements in machines for intermittently dispensing selected and variable quantities of stamps from a stamp strip rolled up and stored in coil form. It is directed more particularly to machines wherein the stamps are formed into relatively wide strips, say, for example, five or more stamps wide, and consequently where the stamp coil has a substantial moment of inertia during the early stages of dispensing.

The use of the so-called trading stamps in conjunction with retail stores operations is widespread. Such stamps are supplied to the retail operator in sheets, perforations being provided to subdivide the sheets into rows of stamps. In many cases the sheets are offered in flat form. The retailer in this instance merely separates the desired number of stamps by tearing along the perforations. However, efforts have been made to provide dispensing machines which are capable of furnishing, in response to the turn of a dial or otherwise, a preselected quantity of stamps. Usually in such machines the stamps are stored with the sheet or strip in rolled up or coil form, the sheet being unwound as dispensing takes place. The present invention deals with a machine of this type.

One of the main objectives of the invention is to provide means in such a machine which overcomes, among others, two troublesome problems which have long plagued dispensing machines in which the stamp sheets are five or more stamps wide. One of these is the problem caused by overrunning of the coil during the stamp dispensing operation, which often results in blacklash of the strip and jamming of the machine. The other is the companion problem of tearing of the strip if the coil is restrained in any way during the unwinding operation, and the strip is pulled too taut.

A further and related object of the invention is to provide means of the character described in which the anti-backlash mechanism is joined with and functions as a part of the protective means for preventing tearing of the strip at the later stages of dispensing. A particular feature of the invention resides in the simplicity of the structure and the limited number of components required for achieving the desired results.

A still further object of the invention is to provide a machine in which the dispensing of stamps from a wide roll or coil is accurate and foolproof. Not only is free feed of the stamps from the machine obtained, but also the feed is accurately indexed so that the stamps are sheared and separated from the roll exactly along the perforations which subdivide the sheet or strip.

Yet another object of the invention is to provide a stamp dispensing machine of the character described in which improved means for locking the machine against dispensing, when desired, is provided.

Still another object of the invention is to provide a dispensing machine in which the stamps are accurately dispensed and which operates smoothly under all conditions of the coil, that is, from the thickest condition to the point of complete depletion.

Further objects of the invention are to provide a compact and light-weight machine for the purposes set forth; to provide a machine which requires little maintenance and service; which is capable of eflicient operation even though handled and manipulated roughly by untrained operators; and which can be manufactured and sold at relatively low cost.

Other and further objects of the invention, together with the features of novelty appurtenant thereto, will appear in the course of the following description.

In the accompanying drawings, which form a part of the instant specification and are to be read in conjunction therewith, and in which like reference numerals indicate like parts in the various views;

FIG. 1 is a top plan view of a typical machine embodying our invention, the protective casing having been removed and certain parts broken away for purposes of illustration;

FIG. 2 is a front elevation of the machine, the casing now being in place, but shown in part in transverse section;

FIG. 3 is an end elevation of the machine taken from the left-hand side of FIG. 1, the casing again being shown in section;

FIG. 4 is a sectional view taken generally along the ing been removed;

FIG. 6 is an enlarged fragmentary section taken along the line 66 of FIG. 3 in the direction of the arrows;

FIG. 7 is an enlarged fragmentary section taken generally along the line 77 of FIG. 3 in the direction of the arrows; and

FIG. 8 is a fragmentary view illustrating the condition of the clutch and ratchet wheel at a point during the operation.

Referring now to the drawings, and initially to FIGS. 1 through 4, reference numeral 10 indicates a generally rectangular horizontal base plate which forms the bottom platform for the machine. The base plate may conveniently be stamped from sheet metal and is provided at the four corners with rubber or plastic pedestal legs 11 secured thereto by bolted connection 12.

The working mechanism is concealed by an open bottom plastic casing having the front wall 13, opposed side walls 14- and 15, rear wall 16 and top 17. Although not shown, the casing in a commercial machine would be provided with a locking mechanism for holding it in place on the machine. However, since neither the details of the casing nor its manner of connection with the machine form any part of the present invention, further description thereof will not be entered into.

Rising vertically from the platform 10 and disposed in spaced apart parallel relation are a pair of side plates 18 and 19. These plates are rigidly joined at their lower edges with the base 10 through welding or otherwise. Extending between and joining the upper ends of the plates 18 and 19 is a bridge bar 20. In the preferred embodiment, the bridge bar rests on horizontal flanges 18a and 19a at the upper ends of the plates and is secured thereto by metal screws 21.

Supported by and between the side plates 18 and 19 is the stamp spindle 22. The spindle is polygonal in cross section through the major portion of its length and is adapted for the winding thereon of a sheet or strip of stamps to form a coil 23 as shown in FIGS. 1 and 4. The opposed ends of the spindle are provided with reduced diameter trunnion axles 24 and 25, which extend, respectively, into and through inclined slots 26 and 27 and seat downwardly on the bottom edges of the slots, which are rounded to form rotary bearing surfaces for the trunnion axles. The slots 26 and 27 are such that the spindle can easily be withdrawn by simply lifting it in a rearward direction to withdraw it through the open ends thereof.

To provide for maintaining the ends of the stamp coil substantially normal to the spindle axis, a pair of circular guide disks 28 are supported by the spindle, one near each end. As best seen in FIG. 6, each guide disk is interposed between the shoulder 22a at the end of the polygonal section of the spindle and the adjacent side plate, n this case, side plate 18. The center area of the disk is dished outwardly to form a boss 28a which in turn is provided with a central aperture adapted to fit loosely over the trunnion axle. The loose fit is to permit a limited degree of wobble of the disk so that the coil is not tightly constricted at its end. While we have shown in FIG. 6 only one of the disks 19, it will be understood from FIG. 1 that the same arrangement is employed at the other end of the spindle.

Again referring to FIG. 6 and also to FIGS. 1 and 3, it will be noted that the trunnion axle 24 extends well to the outside of plate 18 and has rotatably mounted thereon on the outside of plate 18 a toothed ratchet wheel 29. Ratchet wheel 29 is capable of rotation relative to the axle 24. The axle 24 terminates in a threaded axial extension 24a. Screwed onto the extension 24a is a clutch member 30.

As will be explained in greater detail at a later point herein, the clutch member 30 forms part of a lost motion connection between the spindle 22 and the ratchet wheel 29. The latter is provided with a pin or dog 31 extending in an axial direction from the outer face thereof and and offset from the axis of rotation. The clutch member is provided with a flat chord-like, dog-engaging surface 30a having opposed end portions which are capable of engaging the dog 31 upon relative rotation of the clutch member with respect to the ratchet wheel.

The ratchet wheel 29 is resiliently biased in a clockwise direction (as viewed in FIG. 3) relative to the cltuch member 30, and thus toward the position shown in FIG. 3, that is, with the pin 31 engaging the left-hand end of the chord-like surface 30a. The biasing force is supplied by a tension spring 32 connected at one end with pin 31 and at the other end with a pin 33 secured to and extending from the clutch member 30. Preferably the spring 32 is partially received within and guided by a channel or groove 3% formed in the clutch member (see FIG. 6).

Positioned adjacent the ratchet wheel 29 and normally engaging between a pair of the teeth thereof is the detent portion 34a of a pawl 34. Pawl 34 is pivoted intermediate its ends to the side plate 18 through the medium of a screw 35 and spacer bracket 35a, the latter being secured to the side plates as at 35b. At its forward end, pawl 34 is provided with a laterally extending lug 34b (see FIG. 7) which engages between the teeth of a sprocket 36a. The sprocket 35 is secured to the stub axle 36 of the feed roll 37 which extends between side plates 18 and 19 forwardly of and parallel with the spindle 22. While not shown in detail, a stub axle similar to axle 37 is located on the opposite end of the feed roll and both axles extend through corresponding, aligned apertures in side plates 18 and 19 to support the feed roll for rotation about a fixed axis parallel with the spinning axis.

The feed roll may be of any construction desired so long as it is capable of positively engaging with the extending end portion 23a of the coiled stamp strip and is operable to feed the strip forwardly and outwardly through the dispensing stamp opening 13a of the casing. In the particular machine here used for purposes of describing the invention, the feed roll is of molded plastic and is provided on its periphery with spaced longitudinal rows of radial pins 38. The pins 38 are so spaced as to register with perforations in the stamp sheet as the sheet is advanced. Preferably the pin rows are spaced from one another around the feed roll a distance equal to the length of an individual stamp. Thus, the pins will strike the sheet on the perforated cross rows. The number of pins in any given row will depend upon the strength of the sheet being handled. We prefer to have one or more pins per stamp.

The perforations of the stamp sheet or strip are maintained in engagement with the pins 38 of the feed roll as the latter is rotated through the medium of a guide member 39. This member extends substantially the length of the feed roll between the side plates 18 and 19 and, as shown in FIG. 4, is generally arcuate in construction with a forward portion projecting substantially tangential to the feed roll. The opposed ends of the guide member 39 rest on and are supported by arcuate shoulders such as shown at 40 in FIG. 5, which conveniently can be formed by welding or joining a thickness of metal to the corresponding side plate 18 or 19. The underside of the guide member 39 between the shoulders is spaced just sufliciently above the feed roll as to permit free travel of the stamp strip therebetween. To accommodate movement of the pins, the guide member is provided with alternating ribs 41 and slots 42, each rib defining on the underside of the guide member a groove through which a pin is free to move as the feed roll turns. The use of ribs alternating with the slots rather than a continuous series of slots provides additional strength for the guide member and assists in preventing warping.

The guide member 39 is locked in place against fore and aft movement of two upstanding ears 40a which extend upwardly from the support shoulders 40 (FIGS. 1 and 5) and which are arranged to interfit with corresponding notches cut into the ends of the guide member. Downward contact of the ends of the guide member with the shoulders is maintained by a pair of leaf springs 43, one near each end of the guide member. The leaf springs are secured at one end thereof to the guide member and are engaged and flexed downwardly by a locking rod 44 extending between the side plates 18 and 19 and through aligned apertures therein. One end of the locking rod is provided with a knob 44a by which it can be inserted and withdrawn from the apertures. The other end is provided with an annular groove 44]) (FIG. 1) adapted to engage the margin of its adjoining aperture and is held in engagement therewith by the leaf springs whereby to prevent longitudinal withdrawal of the rod unless the groove is disengaged by lateral pressure on the rod.

As the stamp sheet is moved over the top portion of the feed roll 37 by rotation of the latter is a clockwise direction (as viewed in FIG. 4) it is striped from the feed roll and directed toward the dispensing opening 13a by the stripper plate 45. This plate has one edge 45a (FIG. 5) positioned closely adjacent the surface of the feed roll and is inclined downwardly and outwardly to merge with a stationary horizontal shear member 46. The edge 45a of the stripper is provided with spaced pin slots 45b to permit the passage of the pins. The forward portion of the gu1de member 39 overlies the stripper plate and cooperates therewith to provide a confined path for the sheet after transfer from the feed roll to the stripper plate.

When the stamp sheet emerges from between guide 39 and stripper 45 it passes over the stationary shear blade 46. Cooperating with the stationary blade is the movable shear arm 47 having the curved or arcuate blade 48. Arm 47 is pivoted to the front cross piece 49 of the frame through the medium of an elongate pin 50 secured to the arm and which extends through a sleeve bearing 51 formed as a part of the cross piece. A compression spring 52 surrounds the pin 50, hearing at one end against the sleeve bearing, and at the other against a nut threaded onto the pin 50. This arrangement is to accommodate slight longitudinal movement of the pin in the bearing during the shearing stroke, in the manner of known shears of this type.

The shear arm is yieldably maintained in the raised position illustrated by the spring 53 which connects at one end with the downwardly extending leg 47a of the shear arm, and at the other (not shown) with the cross piece 49. Further, the free end of the arm 47 is loaded lightly toward the shear plane by the spring 54 which connects at one end with the arm and at the other with a bracket 55 secured to the forward portion of side plate 19.

The shear is actuated from outside the casing through the medium of a vertical plunger 56 having its lower end disposed above and resting on the upper flange of the arm 47. The plunger is longitudinally slidable in a bearing 57 press fitted or otherwise secured in an aperture 17a in the forward top portion of the casing. A depressor knob 58 is secured to the upper end of the plunger and during the downward stroke is adaptedto enter a recess 17b formed in the top of the casing.

The rotation of the feed roll, and thus the feeding of the sheet outwardly through the shear and dispensing opening, is caused by the manipulation of a dial 60 which is located in an opening 170 formed in the top of the casing- The dial is provided with a series of finger holes 60a spaced circumferentially around the dial near the rim thereof. Preferably the dial is constructed of a transparent synthetic resin, for example, polystyrene or methylmethacrylate. Spaced below the dial and out of rubbing contact therewith is a rigid nonrotatable backing plate 61 on which are inscribed digits which are located in conformity with the openings in the dial. To prevent wear on the inscribed digits they are located away from the hole 60a, being visible through the transparent body of the dial. A stationary dial stop 62 lies in the path followed by a finger engaged in one of the holes and serves to control the extent of movement clockwise for any given turn of the dial.

The dial is supported for rotation about a vertical axis through the medium of a bearing 63 mounted on the bridge bar 20. Connected to the dial, as by screw 64, is a downwardly extending shaft 65 which extends through the bearing and a suitable opening (not shown) in the bridge bar. A bevel gear 66 is secured to shaft 65 for rotation therewith and with the dial.

Gear 66 meshes with a second bevel gear 67 which is keyed to a cross shaft 68 journaled in bearings 69 and '70. The latter are carried bythe side plates 18 and 19. Shaft 68 extends to the outside of side plate 18 and has mounted thereon on the outwardly extending portion a toothed sprocket 71. This sprocket is drivingly connected with the feed roll sprocket 36a by an endless linktype drive chain 72 trained over the respective sprockets and engaged by the teeth thereof.

The slack upper flight of the chain is maintained substantially taut by a chain tightener which includes the roller 73 carried on the free end of a spring arm 74. The other end of the spring arm is afiixed to side plate 18 by an inturned portion extending through a small hole 18b in the side plate and a screw 75 which clamps a loop oflfset in the arm against the side plate.

In order to prevent rotation of the dial in a direction other than that which will produce rotation of the feed wheel in the stamp dispensing direction, we have provided the chain lock escapement pawl 7 6. This is a pivotal member located just above the upper chain flight. It is pivoted at one end to side plate 18 by the shoulder screw 77. The other end has a downwardly extending tooth 76:: adapted to fit between the links of the chain. The tooth is so curved on its rearward edge as to permit it to ride upwardly the cross links and fall by gravity back to locking position between the links as the upper flight advances downwardly. The forward edge is preferably straight and substantially normal to the pivot axis of the pawl so that a wedging action will occur should reverse movement of the chain be attempted.

The radial offset of the hole 60a of the dial and the kinematics of the gear and chain drive are such that for each unit of movement of the dial the feed roll 37 will be rotated a distance sufficient to feed one cross row of stamps past the shearing edge of the stationary shear blade 46. In other words, should the finger hole beside the digit 1 be engaged and the dial advanced until the finger strikes the dial stop 63, one cross row of stamps will extend past the shear. If the dial be moved five units, the feed roll will turn sufficiently to feed five cross rows g past the shear. The stamps are severed by depressing the plunger knob 56. It Will be evident that the feed roll thus serves not only to position the stamps for shearing along a perforated cross row, but also to draw the sheet from the coil 23 as stamps are dispensed.

The dial is indexed to move in unit increments by means of the pawl 34 and the lug 34b carried thereby, the latter of which engages between the teeth of the feed roll sprocket 36a. The pawl lug 34 is always urged into the tooth-engaging position by the spring 80 which connects at one end with the pawl 34 and at the other with a spring bracket 81 secured to side plate 18. The number of teeth on the sprocket 36a is such that for each unit displacement of the dial 60, that is the displacement to move any given hole one digit, the teeth will advance one position. Thus the pawl lug 34b will ride out of one depression into the next for each unit of movement of the dial. To facilitate movement of the pawl lug 3412, the tips of the teeth are slightly rounded.

The movement of the pawl lug 34b over a tooth of the sprocket 36a is accompanied by rocking of the pawl in a direction to disengage the detent 34a thereof from the teeth of the ratchet wheel 29. Care should be taken to insure that the teeth of the ratchet wheel 2? are sufliciently shallow that the detent 34a will be disengaged long before the pawl lug 3% reaches the crest of a sprocket tooth. The quicker the detent can be disengaged, the smoother the operation will be.

As is believed evident, the pawl detent 34b is maintained out of engagement with the ratchet teeth until the pawl lug 34b returns again to the depression between a pair of sprocket teeth.

From the description thus far given, it will be evident that whenever the pawl lug 34b is engaged centrally between a pair of sprocket teeth, the detent 34a is engaged with the teeth of the ratchet wheel. Thus, upon the com pletion of any given dial turn, the ratchet wheel is en gaged and yieldably restrained against further rotation by the detent 34a. The spindle 22., however, is not stopped immediately. It may continue under its own inertia momentum, particularly if the dial has been moved quickly, until the right-hand end of the dog engaging surface 30a on clutch member 30 moves into engagement with the dog 31. The relative positions of the clutch member 30 and ratchet wheel 29 at this point are illustrated in FIG. 8. While the spring 32 tends to decelerate the spindle before the right hand portion of surface 3% strikes the dog, nevertheless, when the coil is large there is sufiicient momentum as to cause the wheel to advance slightly against the resistance imposed by the pawl detent 34a and its spring 80. In other words, the momentum of the coil causes the detent at this instant to serve as a braking ratchet. The additional movement of the spindle is, however, only a small fraction of a revolution, so overrunning is effectively prevented.

Though the clutch member 30 and dog 31 have stopped in the position illustrated in FIG. 8, the initial movement of the dial in the next dispensing operation causes them to resume the relative position shown in FIG. 1. This is because as the detent 34a is disengaged from the teeth of ratchet wheel 29, the spring 32 pulls the ratchet wheel clockwise to bring dog 31 back to engagement with the left-hand portion of surface 30a.

The lost motion connection afforded between the spindle and ratchet wheel by the clutch member 30 and dog 31 is also important in situations where the dial is operated to feed out more than one cross row of stamps at a time. It will be remembered that for each unit of movement of the dial the detent 34a returns to a tooth engaging position. This tends to stop the wheel 29 momentarily. However, the spindle can continue to turn freely. As soon as the detent 34a is again disengaged, the spring 32 draws the dog 31 back to the relative position of FIG. 1. The critical point to note is that the detent 340: must be so constructed and arranged as to again disengage before the right hand portion of surface 30a reaches the dog 31.

From the foregoing it should be evident that even should the strip portion 23a be stretched tightly between the feed roll and coil, the coil is free to advance a limited distance even though the ratchet wheel 29 be momentarily restrained by the detent 34a. This avoids any danger of parting of the strip because of excess tension.

The pawl 34 is also utilized as a part of the mechanism for locking the unit to prevent dispensing when so desired. Referring to FIGS. 1 and 3, it will be noted that located beneath the pawl is a cam 85 mounted eccentrically on a shaft 86 which extneds through the side plates 18 and 19 and terminates in a key lock barrel 87. When the machine is being used, the cam is in the position shown in solid lines in FIG. 3. To lock the dispensing mechanism key 88 is inserted in the lock barrel and turned to bring the cam to the broken line position of FIG. 3. When in this position, pawl 34 is immobilized and thus the dispensing mechanism is firmly locked.

The successful operation of the unit depends in large part on their being a firm nonslipping connection between the stamp coil 23 and spindle 22. We have found that providing the spindle with a polygonal cross section achieves this remarkably well. However, it is not our intention to limit the invention to a polygonal spindle alone, since various configurations involving ridges or knurling will adequately serve the purpose.

From the foregong it will be seen that this invention is one well adapted to attain all of the ends and objects hereinabove set forth together with other advantages which are obvious and which are inherent to the structure.

It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of the claims.

As many possible embodiments may be made of the invention without departing from the scope thereof, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
