Specification of Letters Patent.

Patented Dec. 25, 1917.

Applicationflled September 1a, 1916. Serial No. 119,915.

To all whom it may concern.-

Be it known that I, HERBERT O. TIBBITTS, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Stamp-Vending Machines, of which the following is a. specification.

The invention relates to a vending machine and more particularly to the class of combination stamp vending and coin changing machines. j

The primary object of the invention is the provision of a machine of this character wherein stamps of different denominations will be successively ejected from the machine on the deposit of the proper coins therein and either a single stamp or a predetermined number will be delivered to the operator of the machine when depositing the required amount of money therein.

Another object of the invention is the provision of a machine of this character wherein, on the deposit of one or more coins of different denominations within the machine the requisite change in lieu thereof will be had having an equal valuation to the amount of the coin or coins deposited so that the change can be redeposited within the machine for the ejecting of the postage stamps therefrom, either singly or any number, according to the money deposited within the machine.

A further object of the invention is the provision of a machine of this character wherein the stamp delivering or ejecting mechanism is of novel form so that the same will be automatically set and operated on the deposit of a coin of a predetermined value for the deliver of a stamp or stamps having the same va nation as the coin deposited within the machine.

A still further object of the invention is the provision of a machine of this character wherein the coin changing mechanism is automatically controlled and operated for delivering the exact aggregate amount of coins of lesser denomination than the amount deposited within 'the machine, thereby enabling the operator to obtain the required change for deposit in the machine in procuring stamps therefrom in exchange for the deposit.

A still further object of the invention is the provision of a machine of this character wherein the stamp or stamps ejected from the machine are severed automatically from the strip or strips of stamps, which are in tape form within the machine, when the saidstamp or stamps are delivered therefrom, thus making it impossible for any one to surreptitiously obtain more stamps than entitled to in accordance with the deposit made within the machine.

Astill further object of the invention is the provision of a machine of this character wherein the stam ejectin or delivering mechanism is positive in action and is automatically controlled to avoid any possibility of theft of. the stamps by a surreptitious at tempt on the part of the operator of the machine to extract stamps in excessof the number delivered in accordance with'the value or valuation of the coin deposited "itlierein while the machine is being operated.

A still further object of the invention is the provision of a machine of this character wherein the coin changing mechanism is automatically controlled so as t avoid tampering therewith or the possibility .-.of"obtaining change having valuation -greater. than the amount of the coin valuation deposited within the machine.

- A still further object of the invention is the provision of a machine of this character wherein the coin ejecting or delivering mechanism and the coin changing mechanism are of novel form so as to assurepos1- tiveness in'their operation and to efiect the proper and successful delivery of both stamps and coins from the machine.

A still further object of the invention is the provision of a machine of this character wherein the number of stamps delivered from the machine is automatically counted so that at a glance it can be determined the exact number of stampsejected therefrom.

A still further object of the invention is the provisionof a machine of this character whereimon the delivery of all of the stamps therefrom andalso the delivery of the coins from the change mechanism, the said machine will be rendered inoperative and this fact will be indicated so that any attempt to operate the machine when in this condition will be prevented.

Astillffurther object of the invention is the provision of a machine of this character wherein, on the deposit of a spurious coin therein, or a coin of improper valuation, it will be returned to the depositor without enabling the operation of the machine for the obtaining of stamps or change therefrom by such depositor.

A still further object of the invention is the provision of a machine of this character wherein, on the deposit of small denominations of coins for the procuring of stamps therefrom, the said coins will be supplied or introduced into the coin changing mechanism until the latter is filled to its capacity and thereafter the excess coins are automatically delivered to a depository within the machine, and in this manner the coin changing mechanism will be constantly supfeatures of construction, combination of.

elements and arrangement of parts which will be exemplified in the construction here inafter described, and the scope of the application of which is indicated in the appended claims.

Referring to the drawings in detail, A deslgnates generally the casing of the vending machine, which includes a frame 10 and panels 11 preferably made from metal, the panels constituting the walls of the casing and being securely fastened in the frame 10, and this casing is of the required shape and design, having a curvilinear top 12 supporting a cross bar or plate 13 provided with a series of slots 14 adapted to receive coins of different denominations for the introduction thereof into the machine, while in the front of the said casing are the stamp delivering slots or openings 15 and coin dis charge openings 16 respectively. Arranged about the stamp .delivery slots 15 are escutcheon plates 17 and also about the change discharge opening 16 is an escutcheon plate 18 which carries a cup-like receiver 19 for the coins delivered through the opening.

Arranged rearwardly of the bar or plate 13 and rising vertically from the top 12 of the casing A is a label holder 20 in which are arranged a series of labels 21, having printed or otherwise marked thereon indicia indicative of the denomination of coin to be inserted in the machine for the delivery of stamps therefrom and also the delivery of change in accordance with the deposit within the machine. g

Formed in the casing A and the escutcheon plate 17 below the stamp delivery openings 15 are peep slots 22 for permitting the inspection of counter mechanism to enable a person to determine the exact number of stamps ejected from the machine, the counter mechanism being hereinafter fully described.

Arranged within thecasing A is the stamp ejecting or delivering mechanism which comprises superposed spaced, horizontally arranged shafts 23 and 24 respectively, both of which are supported in brackets 25 fixed to the front corner posts of the frame 10 in the upper portion thereof, the brackets 25 through the openings in the front wall of the casing A from between the said rollers in a manner presently described.

Each feed roller 27 is formed with annular edge flanges 29 which serve as guides between which works the guide roller 28 so that both the feed and said guide rollers will be held against relative movement longitudinally of the shafts 23 and 24 supporting the same, and in this manner the said rollers are held in alinement with each other. Each of the rollers 27 and 28 is formed with a hub extension 30 and these extensions have fixed thereto gears 31 meshing with each other so that the rollers will rotate in unison in reverse directions to eachother for the 1 positive feeding of the stamps, the peripheral surfaces of the rollers being suitably roughened at 32 to avoid the slipping thereof when contacting with the said stamps. Arranged below the shaft 24 and fixed to the front corner posts of the frame 10 is a horizontal bar 33 to which are fixed coiled re tractile springs 34, the same being also fixed to the shaft 23 and serve to tension the rollers 28 to hold the same in close relation to the rollers 27 for the positive gripping of the stamps therebetween to assure the feeding of the stamps during the ejecting or delivery operation of the machine.

Below the feed rollers 27 and secured to the horizontal bar 33 are suitable resetting counting devices 35 which are visible through the peep slots 22 in the-front wall of the casing A and are connected through the medium of gears 36 with the gears 31 so that on the rotation of the feed rollers 27 the counting devices 35 will be simultaneously operated for the counting of the stamps ejected or delivered from the machine, thus enabling a person to determine the exact number of stamps delivered.

Rearw'ardly of the feed rollers 27 and supported upon horizontal side bars 37 mounted in the frame 10 is a platform 38, from which rise spaced pairs of guide ears 39 in which are mounted rocking latch pawls 40 and sliding feed dogs 41 respectively, both of which are acted upon through the medium of springs 42 which normally hold the same in working position, while formed on each of the feed rollers 27 are'the notched latch wheels 43 and the ratchet feed wheels out of engagement with the feed rollers 44,

for operation m a manner presently described. Each ratchet feed wheel 44 has its teeth formed with hook-like shoulders 45 and likewise the engaging ends of the feed dogs 41are formed with hook-like shoulders 46 to cotiperate with the shoulders 45, so

that when the feed dogs 41 have been initially advanced for moving the feed wheels 44 a single tooth it will be impossible for any one to pull upon the stamp strip to cause outward feeding thereof and thereby fraudulently obtain an excessive number of stamps over the amount or valuation of the coin deposited for the operation of the stamp ejecting or delivering, mechanism. In other words, the feed rollers 27 are blocked against rotation for the ejecting of the strips of stamps after the feed dogs 41 have been started in their advance movement or at any time from the initial advancement thereof until the completed advance movement of the same whence the latch pawls 40 have become engaged with the latch wheels 43 and in this manner the possibility of fraudulent manipulation of the stamp ejecting or delivering mechanism is eliminated.

Mounted in the latch pawls 40 are trip pins 47 which project into the path of move ment of cams 48 formed on the feed dogs 41 so that on the advancement of the latter the said cams 48 will act upon the pins 47 to effect the lifting of the latch pawls 40 out of engagement with the latch wheels 43, thereby unlatching the feed rollers 27 to be retated by the feed dogs 41 engaging the ratchet feed wheels 44 forming a part of the said rollers so that stamps will be ejected or delivered from the machine.

Mounted upon the back corner post of the frame A are bearings 49 in which are journaled trunnions 50 of a coin carrier comprising a downwardly tapered housing 51 having formed interiorly thereof the coin chutes l or'slots 52, 53, 54 and 55, respectively, the

being adapted to receive coins of the valuation of one cent or penny, the chute 55 adapted to receive the coins of twenty-five and fifty cent valuation, the chute 53 adapt.

ed to receive coins of five cent valuation and the chute 52 to receive coins of ten cent valuation, and these coins are adapted to be carried in the housing 51 of the carrier for operating the stamp ejecting'or delivery mechanism and the coin changing mechanism in a manner presently described.

The chute 54 is formed with lateral pasmost end for the positioning of one or two one cent or penny coinsin said passages 55 and 56 to close holes 57 and 58, respectively, formed in thehousing "51 "for intersecting the said passages 55', and. 56 for the. operation of an actuating fork 59 slidably mounted upon the platform 38, the said fork being supported for swingin movement upon a pivot 60 which is fixe in a runner 61 movable on the platform 38 which is formed with a guide slot 62 receiving a' guide plate 63 secured to the h runner 61, and to this plate is connected a follower 64 which holds it in the slot 62, and inthis manner the fork 59 is guicled in its movement on the platform 38, the pivot 60 being surroundedby a coiled tension spring 65 w ichacts upon the fork 59 to hold the same in its shifted position when swung either to the right or to the left of -the machine. The fork 59 has formed in one limb a notch 66 to receivea.

pin 68 fixed in one of the feed dogs 41, While the other limb of the fork 59' is. adapted to engage a pin 67, mounted in the other feed .dog 41, and thisfork 59 alternately engages the respective pins 67 and. 68 carried by the feed dogs for the operation of the same to effect the independent rotation of the feed rollers 27 to eject or deliver from the machine stamps of different denominations.

The fork 59 atits rearmost end is formed.

with abutmentwings 69 which are engaged by the housing 51 of the carrier so that the said fork 59 will be automatically moved to a neutral point for its ineffectiveness on the feed dogs 41 when the carrier is advanced or swung forwardly without, coins of. the one cent or penny valuation being deposited therein to close the holes 57 and. 58 thus preventing the operation of the stamp ejecting or delivering mechanism. Out from the platform 38 and struck upwardly therefrom are bearings 70 to which .is pivoted a yoke 71 havin mounted therein an operating handle 72 whlch protrudes without the casing A at the top 12 thereof through a slot 73 formed in said top 12, and this handle 72 is adapted to work in the slot 73 forthe movement of the yoke 71 by hand. Pivoted to the yoke-71 so that on the swinging of the yoke 71- forwardly the carrier is likewise moved-in this direction, is aU-shaped bail 7 4 which is also pivoted to thevhousing 51 of the carrier so that on the swinging of the yoke 71 forwardly the carrier is likewise moved in this direction, and to this bail 74 at the rear of the housing 51 is connected. acoiled retractilespring 75 which is also connected to the frame 10 of the casing A, .the spring 7 5being designed to return the carrier to normal position or move the same rearwardly after its forward movement by operating the handle -72 by hand. sages 55 and 56, respectively, at itslower- [Formed in the front wall ofthe housing 51 of the carrier'below the holes 57 and 58 is aslot 76, while formed on the said front wall of the housing 51 at a'point above the holes 57 and 58 is a hanger 77 in which is pivoted aweighted trip yoke 78 carrying a coin stop 79 normally projected through the slot 76 into the path of movement of the coins within the passages 55 and 56 of the (111M554 so as to hold the coins deposited therein for closing the holes 57 and 58 and positioning v the said coins inithe path of fingers 80 and, 81, respectively, the finger 80 being longer: than the finger 81 so that when engaged'by a coin closing the'hole 57 the fork 59 will be automatically thrown to the right hand side of the machine for the vengagement of'its other limbjwith the pin 68sothat inf-this manner the feed rollers 27 are independently operated. The, chute'54 is formed with a deflector. wall 82 .which 'fserves to deflect a single coin' of the proper, denomination, namely, one cent or penny, into the right hand passage 56 so that this coin will engage the finger 81' for the automatic shifting of the fork ,59to bring the same into a position forfengaging the pin 68 carried by the dog 41 at the left hand side of the machine and thusthe feed roller 27 at; this side will be operated on the swinging of the carrierin a forward direction to eject a stamp having alike valuation of the 'coin deposited within the carrier. It will be impossible to operate the feed roller 27 at the right hand side of the machine when a single coin has been inserted in the chute 54. However,-on the insertion of a second coin of the one center penny denomination withinf'the chute 54 the same will .enter the passage 55 'thus' both holes '57 and 58will be closed in the housing 51, and these coins will be held in position by the stop79 ,for this purpose so as to act upon the fork59 for moving the same to the right when the carrier is swung forwardly, so that the roller 27 at ,the right hand "side of themachine will be operated for the eject ing or delivering of a stamphaying a valuathe tip 850i which is adaptedforv engagement with the stop 79 on therearward move ment ofthe carrier for disengaging the stogp from the slot 76 in, said housing toperm it the coinswithin the passages '55' an d'. 56 to pass out of the same into the opening 83 or its the discharge of the said coins into a trough 86 stationarily mounted on the frame and projected through the opening 83 in said housing for the discharge of the coins from the chute 54 into the coin changing mechanism hereinafter fully described.

The spring 84 rearwardl'y of the tip 85 is formed with a swell 87 which engages one edge of the opening 83 so as to automatically disengage the tip 85 from the stop 79 on the rearward movement of the carrier for permitting the stop 79 to assume normal position within the slot 76 in the housing 51 and thereby retain coins of the proper denomination deposited within the chute 54 in the carrier for the further operation of the machine. The passages 55' and 56 are formed with nibs 88 so as to properly contract the said passages to assure the retention of the proper coms deposited within the ,chute 54,

yet if an improper coin, that is, one of a smaller .size than the coin having the valua tion of one cent or penny, is de osited therein the same will pass the ni s 88 and be delivered from the machine for its return to the depositor in a manner presently described.

Secured centrally to the horizontal bar 33 below the shaft 24 centrally thereof is an inverted substantially L-shaped bracket 89, on the horizontal portion of which is fixed a bearing 90 having secured therein a shaft 91 on which are j'ournaled feed gears 92 which are arranged at opposite sides of the bracket 89 and each is formed with a hub 93, in the inner end of which are mounted at intervals feed In 94 which, in this instance, are four in num r, and are concentrically disposed about the hub, while formed in the inner side of each gear 92 is an annular groove 95 providing an internal annular shoulder 96 having at intervals-therein notches 97 which are disposed an equal distance apart and likewise the feed lugs 94 are disposed an equal distance apart. Secured to the bearing 90 is a hanger 98 to which is fixed the forward end of a rectangular shaped forwardly inclined guide frame 99, the rear end of which is fixed to the bracket 89, and in this frame are mounted sliding p'lungers 100 having pivotally mounted in each a feed dog 101 which formed with a notch 102 in its free end torecelve any one of the lugs 94, and this dog is acted upon by means of a sprin 103 carried by the plunger 100 so as to ho d it in the path of the lugs 94 for positive engagement therewith. Arranged within the grooves 95 in the. gears 92 are latchpawls 104, which are formed with a' tooth 105 for engagement in any one of the notches 97 in the shoulders 96, and these latch pawls 104 are supported upon a spring 106 fixed'upon a bracket 107 mounte on the frame 99, which sprin serves to hold the pawls normally in la ed engagement with the gears 92, the pawls 104 beingformed with elongated slots 109 through which work pins 108 suitably mounted in the sides of the frame 99 and also said pins 108 engage in openings 111 in hanger blocks 112 loosely mounted in the grooves 95 in the. gears 92, the latching pawls 104 being formed with trip extensions 113 provided with cams 114 which engage andare acted upon by the pivots 115 connectin the feed dogs 101 to the plungers 100, w ich pivots 115 extend through elongated slots 116 formed in the side of the frame 99 to protrude into the path of the cams 114 so that on the advancement of the plungers 100 the pivots 115 will engage the cams 114 to move the extensions 113 and likewise move the latch pawls 104 out of engagement with the gears 92 and at the same time the feed dogs 101 will engage the lugs 94 for rotating the said gears 92 which mesh with pinions 117 loosely jour naled'upon the shaft 24 the pinions being formed with clutch members 118 which are adapted for lockin engagement with companlon clutch mem rs 119 formed on the feed rollers 27, therpinions 117 being acted upon by means of coiled exipansion sprin 120 which surround the sha 24 so that t e clutch members 118 will'lock with the companion clutch members 119 when the gears 92 are rotated for the turning of the feed rollers 27 to eject or deliver stamps in predetermined numbers from the machine.

Connected with the guide frame 99 are leaf springs 121 which are also connected with the inn rs 100 so as to hold the same in norma position to be acted upon by coins deposited within the carrier when the latter is advanced.

Formed in the housing 51 of the carrier below the opening '83 therein are holes 122 which intersect the chute 55 and are adapted tobe closed by coins deposited within said chute, the coins being stopped durin the gravitation thereof within the chute 55 to position the same for closing the holes 122 y means of trip stops 123 which are supported upon weighted yokes 124 pivotally mounted upon the housing 51 and working within a suitable slot formed in the latter,

and these coins, when closing the holes 122, will engage the plunger's 100 when the carrier is moved forwardly so that the plungers will be actuated for the unlatching and tuming of the gears 92 which, in their turn, ro-

tate the feed rollers 27 for ejecting a predetermined number of stamps for the deliver- 111g of the same from the machine.

A Detachably mounted upon the ends of the shaft 91 are stamp reels 125 on which are normally wound stamp strips 126, which latter are trained over guide rolls 127 and between the rollers 27 and 28, the said reels 125 being detachably fastened upon the ends of the shaft 91 through the medium of cot-
