UNITED STATES CHARLES S. GONE, F LA GROSSE, WISCONSIN.

STAMP-VENDING MACHINE.

Application led July 11,

To all 'whom 'it may concern Be it known that I, CHARLES S. CoNn, a citizen of the United States, residing at La Crosse, in the county of La Grosse and State of lVisconsin, have invented certain new and useful Improvements in Stamp-Vending Machines; and l do hereby declare the following to be a full, clear, and exact description of 'the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

AMy .invention has fr its immediate object to lnovide an improved machine for vending' and mechanically delivering postage stamps that are in rolls with the individual stamps partially separated by perforated lines. The improved machine, however, is not limited to the vending and delivering of postage stamps, but is capable of much more general use, being adapted for the feeding and delivery of various devices, such as theater, or other tickets, for example, which are in ribbon form, transversely perforated or cross scored or marked at intervals.

Tn'the following description, however, the machine will be described as designed for, and used to vend and deliver postage stamps. The roll of postage stamps is transversely perforated on lines between the individual stamps.V

V(lne feature of my invention is directed to an improved feeding device for feeding the stamps, or strip, by virtue of perforated lines. This novel feeding mechanism and other associated highly important novel devices and combinations of devices will be described in connection with the accompanying drawings, wherein like characters indiate `like parts 'hroughout the several views.

Referring` to the drawings:

Fig. l() is a perspective view showing a modified form of the stamp or ribbon feeding drum.

The machine illustrated is a duplex vmachine, that is, is adapted to feed the Stamp from two laterally spaced rolls mounted on inde'iendent reels.` There is an independent feed mechanism for each roll of stamps and each suoli mechanism is independently coin controlled, but the two feed mechanisms have a common actuating device adapted to be rendered operative by the coin deposited in the one or the other, or both of the mechanisms.

Preferably, the mechanism is all, or' practically all inrlosed within a suitable casing. This casing, as shown, is rectangular and comprises a base portion 11, a top 12, connecting corner post 13, and glass side plates 14. The numeral indicates a direction board which constitutes no part of the present invention, but, as shown, is secured to the rear of top 12 and rises therefrom. In Fig. 2, a weighing scale, indicated as an entirety by the numeral 16, is applied on the base flange of the direction board 15, in position where purchasers of stamps may use the same.

Extending about centrally through the casing and secured to the base and top, is a column 17, the upper end of whichis threaded and provided with a nut 17a. The sides base when nut 17l is removed. Column 17,

on its front face, is formed with notches or serrations k18 that perform a function hereinafter noted. i

The ribbon-like rolls of stamps are indicated by the character y, and, as shown, they are contained on depending reels 19. `The reels 19 are rotatively mounted on the opposite ends of a transverse spindle or idle shaft 20, and are removable therefrom when outer cotter vcorners 21v are removable from the ends of said spindle. Spindle 20 is passed through perforations in the upper laterally spaced arms 22a of a pair, of bearing 'metal brackets 22 that are rigidly secured. to verticallyV disposed coin troughs or channels 23. .These coinl channels 23 are open at front, and at their lower ends, have laterally turned base flanges 23%1 bolted, or otherwise, rigidly secured to the base 11. Just below the extreme upper ends the trough channels 23 are provided with horizontally projecting flanges 25sb that are bolted, or otherwise, rigidly secured to a tie plate 24. Tie plate 24 extends under the front edge of top plate 12, is perforated to pass the threaded upper end of column 17 therethrough, and is normally clamped to the column by a nut 17 .but is not removable with theV top plate, or y with the casing proper.

From the reels 19, the stamp ribbon i/ is passed downward against ribbon guiding plates 25 that have segmental portions 26 formed with internal'clearance channels 26a.

Guide plate 25 has side webs 26", and each complete guide plate is secured to and located witliin a hoppenshaped supplemental bearing, frame 27. These supplemental frames 27 are laterally spaced, at their upper side portions are rigidly connected to flanges of the bearing frame 22, preferably by screws 28, and at their lower portions, have depending brackets 27L bolted, or otherwise, ri idly secured to the base 11.

lVorking rotatively within the concave portion of each guide plate 25 is a stamp or ribbon feeding drum 29. Each feed drum 29 isV secured to its own shaft 30, and the two shafts '30 are axially aligned and rotatively mounted in the side webs of the respective guide webs 2Gb and in the side webs of the frames 27, and at their inner ends, also, in a central bearing 31 that is rigidly secured to column 17 and to adjacent portions of the bearing frame27. 4 `Feed drum 29, for engagement with the perforations in the ribbon between individual stamps, is provided with sharp and small l projecting teeth 32, shown as formed on the outer edges of thin metal bars 33 that are radially inset into the peripheral portion of said drum and extend parallel to the axis thereof with the teeth 32 aligned to move through the segmental channels 26b of the guide plate 25. Here it should be noted that between theJ peripheries of the drum, and the concave surfaces of the guide plates 25, there is just sufficient clearance to permit the stamped ribbon to pass freely without friction but with the teeth 32 projecting through the perforations and into the clearance channels 26u.

Here it snould be noted that the drum shafts 30, at their outer ends, are provided with a knob 80 (see particularly Fig. G), by means of which, when the enclosing case is removed from the base, said drum may be manually rotated, at will.

Located just in front of the columns 17 is a vertically movable plunger 34,y which, at its lower end portion, works with ample clearance through a plate 35 and is guidedv by a flange 36, which plate and flange project horizontally from the fixed bearing bracket 22. The upper portion of said plunger 34 works through and is guided by the fixed topk guide plate 24 and, at its extreme upper end, is pivoted to the intermediate portion of an operatinglever 37. Lever 37, at one end, is provided with a kno`EF38 adapting it to be easily depressed, while its short end is con-V nected by a link 39 to a lug on the top plate 12. j

Coiled spring 40 surrounds plunger 34 and is compressed between guide flange 36 and a yoke-like crosshead 41 that is rigidly lsecured to said plunger and is normally just below the top plate of the casing.

'A pair of rack bars 42 are attached at their upper ends to the opposite vends of the crosshead 41, and these racks depend through and are guided for verticfl movements by guide plate There is one of these rack bars for each side or section of the machine, and each rack bar meshes with a spur pinion 43 that is mounted to rotate and slide on a short shaft 44 journaled in the central bearing 31 and in the adjacent side of the hopper-like bearing frame 27. At one end, pinion 43 has a half clutch 43a, with which latter is engaged the forked lower end of shipper lever 45 that is intermediately pivoted to a vertically projecting arm 31a of the central bearing 31. Lower end of lever 45 is yieldingly pressed toward the left, in respect toFig. 3, by-'a suitable support or coiled spring 46. An upwardly spring pressed lock dog 47 pivoted to the extreme upper end of arms 31n works through the slotted upper end of each shipper lever 45 and is provided with a shoulder adapted to engage the extreme upper end of said lever and to hold the same normally in the position shown in Fig. 3.y

Each shipper lever 45 has a tripping cam lug 48 that is adapted to be engaged by a cam flange 48 on thel co-operating rack bar 42.

ISecured to each shaft 44 is a spur gear I 49 provided on its hub with a half clutch 49a adapted to be engaged by the half clutch 43a of the sliding pinion 43. Here it should be noted that said pinion 43 is a wide-faced pinion adapted to maintain mesh with 'its co-operating rack bar 42 when slid to diderent axial positions on its shaft 44. The pinion 49 of each shaft 44 meshes with a spur gear 50 on the shaft 30 of the cooperating feed drum 29.

By the respective feed drums 29, the stamp ribbon is fed over the curved bottom of its cooperating hook-like bearing frame 27, and the stamps will be severed by the action of a knife that cooperates with the extreme edge 27a of said frame, as a shearing edge. The knives 51, of which there is one for each "shearing edge 27, are flat blades which, at

their inner ends, are riveted or otherwise rigidly secured to a knife carrying head 52. This carrying head 52, as shown and provided, is a stamped metal structure, the intermediate portion of which is rigidly secured to the lower portion of the plunger 34 (see particularly Figs. 8 and 9).

Pivoted at its lower end, at 53, to the knife carrying head 52 for cooperation with one of each knife mechanism, are so-called trip levers 54. The 'upper ends of these levers54are curved rearwardly and provided at their free upper ends with laterally projecting trip lugs or flanges 55 'that cooperate with the free ends of the lever locking dogs 47 in a manner which will hereinafter be described. The trip levers 54 are yieldingly pressed forward or toward the right, in respect to Fig. 7, by the endsI of a spring 56 that is intermediately connected to the plunger 34 (see Figs. 7 and 8). At their intermediate portions, trip levers 54 are provided with laterally projecting cam pins or lugs 57, and at their front edges, with forwardly projecting coin-engaging shoulders 58. Cam pins 57. cooperate with cam bars o9 rigidly secured at their upper ends to bearing brackets 22. These cam bars 59 have vertical cam surfaces 59 and curved cam surfaces 59h which operate, as hereinafter described.

As the knives descend to sever the stamps., they are engaged by the oblique edges of presser bars 60 pivoted at their upper ends at 61 to the arms 22a of the respective bearing frames 22. The lower endsof presser bars G0 are shown as equipped with leaf springs 62 that engage the backs of the coin channels 23 (see Fig. '7) and force the said lower ends of said presser bars toward the shearing edges 27a.

As the stamp strips are fed to the shearing edges 27, they pass under the segmental flanges G3 of strip clamping levers 64 that are secured to a small common rock shaft 65 that extends through both bearing frames l27 and is jonrnaled in the side plates thereof. These levers 64, close to their pivots, are provided with eccentric clamping edges 66 which, when said levers 64 are rocked to the right, in respect 'to Il ig. 7, engage and press the stamp strips against the bottoms of the frames 27 adjacent to the shearing edges 27a thereof. Levers 64 are yieldingly pressed to the right, in respect to Fig. 7 by suitable springs G7. The upper ends of said levers 64 are curved or obliquely set and their free upper ends normally engage the rear faces of the respective knives 5 The action of these levers will be fur ther considered later on.

In this preferred arrangement of the machine, the right hand stamp feeding drum 29 is arranged to simultaneously feed two two-cent stamps for each nickel deposited in the right hand coin channel, and hence, is, for each feed movement, given a half rotation, and the left hand stamp feeding drum will be arranged to feed four one-cent stamps for each deposited coin or nickel, and hence, will be given a complete rotation. For the accomplishment of the above results, ratchet wheels (38 are secured to the respective feed drum shafts 30 adjacent to the cooperating feed drums (see particularly Figs. 1, 5 and For reasons above indicated, the right hand ratchet wheel 68 will have two diametrically opposite teeth while the left hand shoulder wheel will have but one tooth.

For independent cooperation with these ratchet wheels, l provide downwardly spring pressed retaining dogs G9 pivoted to the adjacent sides of the frames 27 and having at their free ends, extended lingers 69L that normally rest upon the backs of cooperatingf knives 51. and are thereby held raised and in inoperative positions. When the knives are depressed, dogs 69 will follow until their .shoulders engage an aligned tooth of the cooj'ierating ratchet wheel G8, and thus back- `ward rotation of the feed drum is positively prevented while the knives are operating. To prevent over rotation of the stamp feeding` drums in forward direction, leaf springs 70 are anchored at one end to the respective frames 27 with their free ends engaged with the respective gears 50.

lhen plunger 34 is depressed. by a depression of the lever 37, crosshead. 41, with its rack bars 42 and the knife carrying head with the two knives 51. will be mover'L downward, as already indicated. To insure full downward movements of the plunger and parts carried thereby, crosshead 41 (see Fig 5) is provided with a centrally spring-held full stroke pawl 71. lhen plunger is depressed.. dog 71 will yield in an upward direction and pass over the teeth or serrations 18, column 17, at an oblique angle thereto. which will prevent return movement of the llO plunger until the said dog has been carried below the said serrations 18, lwhereupon the said dog will yield in a downward direction and permit return movements of the plunger and the parts carried thereby.

When afcoin X (see particularly Figs. 5 and 7 is inserted in one of the coin channels, itwill drop therein until it is intercepted by a detaining-spring 72 applied to the back of said channel with its free end projecting into the same. Just before the coin is stopped by the detaining spring 72, it strikes the free lower end of a coin cut-off lever 7 3, that is intermediately pivoted to the respective coin channel and has a free open end 7 3 which is arranged to enter the upper portion of the said coin channel and prevents a second coin from being dropped into the channel until the previously deposited coin has been forced further downward in the said channel by a subsequent depression of the operating plunger 34. i

y,From the lower ends of the coin channels, the coins will pass through a slot 74C in base ll and into a coin boX 7 5 shown as contained within the said hollow base ll. At the extreme lower end of each coin channel, however, is a secondary coin intersecting spring 7 (3 which is so located that there will always be several, say four deposited coins in the lower portion of each channel below the first or primary intersecting spring 72. These intersecting springs 72 andV 7 6 will yield to permit coins to pass under pressure produced, as hereinafter described, by depression of the operating plunger 341-.

The several stamps will be delivered into inclined stamp receiving pockets 77 that are open at the front end of the case for the removal of the stamps. Fivotally mounted in each pocket 77 at 78 is a curved stamp intercepting blade 79 that is provided with an upstanding perforated lug 80. The lug 80 of each stamp intercepting blade 79 is loosely pivoted to the lower end of a lever 8l that is intermediately pivoted at 82 to the adjacent bearing frame 22. The upper ends of levers 81 are shown as forked and are pivotally connected at 83 to the short lower ends of upper levers 84. that are also pivoted to bearing frames 22. These upper levers Sil, at their free upper ends, are provided with coin intercepting blades or lingers 85 adaptedto enter the upper` portions of the respective coin channels (see particularly Fig. 5). Levers 8l, at their lower rear edges, are provided with oblique cam surfaces 86 adapted to be engaged by the respective knives 51 when the latter are depressed.

G illustrates a modified forni of stampribbon feeding drum or roller which conr prises disk-like head portions 87 and an in'- tervening body portion 88 that is rectangular in cross section. This angular body portion is shown as provided with four sides, b ut might be provided with more or less such sides, but should have quite sharp edges spaced to correspond to the distance between the stamps so that the said edges will bend the stamped ribbon on its perforated lines.

Operation: The operation of many of the devices above described has been made clear from the foregoing description. But the operation of the machine, as an entirety, may be summarized as follows:

The'coin to be deposited is assumed to ber a nickel. If deposited in the right hand coin channel, the purchaser will obtain two twocent stamps and if deposited in the left hand coin channel, the purchaser will receive four one-cent stamps, this being in accordance with statements already made.

Vhen a coin is deposited in a coin channel 23, it will drop therein until it is intercepted by spring 72 (see Fig, 7). In this position, the coin also engages the lower end ofthe cut-olf lever 73 and causes the upper end of said lever to move into the position shown in Fig. 5, sol that it will prevent a second coin, at this time, :from being dropped into the said channel beyondV the position shown at the top in Fig. 5. The coin deposited and held by the intercepting spring 72, as shown in Fig. 7 will be in position to be engaged by the driving lug 58 of the so-called tripping lever 54: in the position shown in Fig. 7.

v The coin will dropfin the channel past the said driving lug 5S, because the saidlever 5l is then held in a retracted position by engagement of its cam pin 57 with the vertical cam surface 59Cl of fixed cam bar 59.

rllhe stamp feeding, cutting and delivering action is produced by a downward movement of the main plunger 34, and this plunger is forced downward by depressing the knob 38 of plunger lever 37. If no coin is deposited in the channel, as shown in Fig. 7 and plunger 34: is depressed, as stated, there will be no feeding of a stamp Strip, for 'the following reasons: Tripping lever 54 is pivoted' to knife carrier head 52, which, in turn, is secured to the lower portion of plunger 34, and hence, the said tripping lever, regardless of whether or not a coin is deposited, will be carried downward with the said plunger. wWhen no coin is in position, as shown in Fig. 7, and the said parts are moved downward, as stated, cani pin 57 of lever 54- will immediately move below cam surface 59l and will follow cam surface 59h, thereby carrying trip lug 55 forward,or to the right, in respect to Fig. 7, to a point forward of the free end of loc-k dog a7,r so that the said lock dog will be left in this operative position shown in Fig. 3 and shipper posited, as shown in Fig. 7, and the plunger and other parts noted are depressed, as stated, then cam pin 57, on leaving the lower portion of vertical cam surfaces 59, will move slightly forward or toward the right and just far enough to carry the tripping lug 55 over the free end of the cooperating lock dog 47, and the said tripping lever 54 will be stopped in this position by engagement of its lug 58 with the upper edge of coin Hence, further depression of said plunger and the said tripping lever, lug 58, acting on the coin, will force the same below the intercepting spring 72, and thereupon still` further downward depression of thesaid parts will carry cam pin 57 into engagement with the lower vportion of cam surface 59", and the latter will cam the said lever 54 rearward or toward the left,` far enough to disengage lugv59 from the coin, leaving the coin free to fall against lower intercepting springs 76, or onto other coins held in the lower portion of the channel by said spring 76. The statements abovemade are, of course, true, in respect to both sides of the machine. In the above arrangement f of the machine, coins may be simultaneously deposited :in both channels and the delivery of stamps may be simultaneously made from both sides ofthe machine, or said feedinor operations may be entirely independent and take place at different times.

When shipper levers 45 are released from lock'v dogs `47, springs 46, acting on said levers, shift pinions 43 on shafts 44, thereby causing half clutch 43a to engage half clutch 49, and thus connect the respective feed drums 29 through the said gears, so that they will be rotated by further downward movements'of the plunger and racks, and this, of course, produces the feedmovements of the stamp ribbons. When the said racks nearly reach the limit ofl their downward movements, cam surfaces 48" come into action on cam .lugs 48 and thereby force. the respective shipper levers 45 back to their normal position shown in Fig. 3, and in such positions, the said shipper levers will then be again locked by automatic engagement therewith of their respective feed dogs 47.

IThe knives 51 are forced past the shearing edges 27a to receive the stamps on the perforated lines between the stamps, approximately at the limit` of the downward movement of the plunger 34. 'The said knives will be pressed against said shearing edge by the spring pressed bars- 60. Also, andV asalready described, as the knives approach their cutting positions, the stamp strip will ybe gripped by the eccentric portions 66. Moreoven as the knives approach their lowermostfpositiona they yactfon the oblique edges 86 off-levers 81 andcause two actions, towit, they vmove intercepting blades 85-into the upper portionscf the respective coin channels 23 and rock the stamp intercepting blade 79 downward, so that it will intercept and cover up the severed stamps and thus eliminate the possibility of stamps, other than those punched, from being pulled from the roll by hand manipulation, or otherwise.

As already indicated, this so-called stamp vending machine is not limited to the vending of stamps in ribbon or roll form, but is capable of much wider range of usage. For instance, it is customary to sell motion picture tickets in ribbon form. kThis machine is well adapted'for the vendingy and delivery of such tickets.
