A- F LE- r teriorly of the container so that it may be operated by the purchaser. A structure answering generally. to the above is disclosed in the Warren patent above noted, but inasmuch as this invention is concerned prima-rilywit-h a coin mechanism by which the dispensing operations are governed, a further detailed description of the latter is thought unnecessary.

T he cam lage.

-may best be understood by reference to Figs. 4 and 6. As shown, this carriage is provided with a main wall 22 from whose ends depend legs 23, each of which is turned at its bottom to provide a foot 24. Ears 25 are extended from the upper part of the frame within each of whlch as Well as the feet 24 is mounted a journal 26 adapted to facilitate free sliding movements of the carriage upon the guide rods 19. From the side of each leg 23 extends an ear 27 which provides a mounting for a rock shaft 28 which carries at each end a pin 29 adapted for projection through a slot 30 that .is formed vertically within the partition plate. By means which-will be presently described, the shaft 28 is adapted to be rocked with each upward movement of the carriage so as to pro ect-these pins 29 through the slots 30 into engaging relation with thepapers or other commodities that are arranged on the opposite side of the partition plate.

The coin chute.

The mechan'sm that is peculiar to this invention includes a coin chute whose receiving end 31 extends to the exterior of the container where coins of a proper value may be inserted. At the receiving end of the chute, means are provided for preventing the reception of coins conssting of a finger 32 which is formed as part of a wire 33 which is pivoted at 34, having .one end 35 normally projected through an o ening 36 that is formed laterally of one o the slots 30, a spring 37 tending to maintain the wire in this relation. As long as articles remain within the container, the one proximate to the plate 17 will push back the wire end 35, thereby removing its finger end from a position where it may interfere with coins that might otherwise be inserted within the chute. The effect of this is to permit the insertion of coins only when there are articles in the container ready to be dispensed.

A short distance from its receiving end the chute is tilted over somewhat and is dsposed in a course that is partially vertical, but principally horizontal. The angular disposition of this portion of the chute is best shown in Figs. 1 and 12, where I have arranged a switch by which the smaller coins are shunted off into one branch, the larger coins being guided throu h another branch of the chute. At the p ace where the switch is located the chute walls are angularly inclined and are provided with in-.

wardly projecting guiding flanges 38 spaced apart sulficlently to permit the smaller coms to flop over by gravity into a lower branch chute 39, the larger coins, however,

are maintained in an upper position byv these flanges 38 so as to be guided into a second a branch chute 40. For convenience in denomination, these two chutes will be termed the penny and nickel chutes respectively, as they are adapted to receive coins of these dimensions.

The coin setting mechanism.

As already suggested, the present machine is adapted for operation only after coins have been inserted of the required number and denomination. A means is accordingly provided for setting the mechanism to oprate with (1) from one to four pennies, (2) with one nickel, or (3) with one nickel and one to four pennies, thus adapting the machine, in the capacity herein shown, to 0p erate with from one to nine cents. A greater range of capacity would require merely that the parts to be hereinafter described be duplicated or reproportioned according to the purpose in View.

The chute 39 extends downwardly to present its delivery end operatively to a coin box 41 that may be positioned conveniently between the legs of the carriage, as best shown in Fig. 1. A branch chute 42 is arranged parallel therewith and has its upper 1 end formed with a side opening 43 in proximitv to a side opening 44- that is formed in the chute 39, the purpose being to provide a means of transferring coins from one into the other. Such a transfer, however, may take place only after a predetermined number of coins has first passed into the chute 39, and to accomplish this result use is made of a lever 45 (see Figs. 3 and 11) that is pivoted as at 46 to a bracket support 47 to provide an upper end portion 48 and a lower portion 49 from which latter part extends a finger 50 that is adapted to be projected within the chute 39 at a point below its opening 44, a spring 51 acting normally to tie) LML'IM rt Fig. 11, these parts are shown in the position that they occupy when the carriage has been raised where it will be noted a shield 52 engages with the upper end 48 of the lever to press the same toward the partition plate, thereby withdrawing the finger 50 from its projected position with the chute 39.

In Fig. 8 I have indicated the uppermost position of the finger 50, where it stands slightly above and awe from the lower edge of the opening at. coins descending through the chute 39 are shunted laterally by the finger so as to pass through the openings 44 and 43 into the branch chute 42. The finger 50 may be set in other positions, however, according to the number or value of the coins that are requisite for the purchase of the commodities within the container. A means for vertically adjusting the bracket support 47 is clearly shown in Figs. 7 to 9, and includes a stud 53 carried thereby, adapted to project through a slot 54 formed in the partition plate, a thumb nut (see Fig. 11) being threaded to the stud on the reverse side of the plate. The portion of the plate in which the'slot 54 is formed lies in a plane that projects slightly away from the articles to be dispensed, so as to provide a space on the side facing the commodities which will accommodate the adjusting thumb nut, thereby obviating interference with such articles. Extending laterally from the slot 54 are notches 55 within any one of which the stud 53 may lie to locate the bracket suport in a definite position of vertical ads ustment, by which theposition of the finger 50 within the chute 39 is also determined. According to the construction shown, the bracket support may be adjusted in any one of four positions, this number of adjustments being, of course, variable, depending upon the number of notches 55 that are provided.

As shown in lliig. 8, the finger 50 is in its u permost position where it acts to trans er into the branch the first coin that passes into the chute 39. In the position shown in Fig. 7, the bracket support is adjusted one notch. lower, thereby setting the finger 50 to retain within the chute 39 only the first .coin that passes therein, the coin so held acting to shunt the second inserted coininto the branch chute 42. In Fig. 9 ii have shown the finger as set to its lowermost position, where it may retain inoperatively three coins w thin the chute 39, the upper one of which 1s so positioned as to shunt off into the branch chute 42 any fourth or succeeding coins that may he iiitroduced into the chute 39.

The coin and carriage release mechanism.

The lower of the nickel chute t0 and hen so positioned, a

branch chute 42 are obliquely inclined away from the partition plate, each having a delivery end which points toward the rock shaft 28 when the carriageis down, the delivery end of each chute being normally closed as by means of a gate 61 formed with companion cars 62 extending therefrom into pivotal relation with a pin 63. Each gate is normally held in closed position upon its chute by a spring 64 one of whose ends may be attached to the gate and the other to a fixed part of the chute. It will be noted that the delivery ends of these two chutes are arranged closely side by side, and provide a mounting for a pin 65 which ex-- tends laterally across from one to the other. This pin carries at each end an arm 66 adapted to engage with the ears 62 so as to open both gates 61, one of the arms (36 being provided with a finger 67 that is extended forwardly in position to be depressed by the rock shaft 28 when the carriage 21 is in lowermost position, the effect being to normally maintain both gates open against the tension of their springs 64. Mounted upon the rock shaft 28 are two dogs 68 and 69 in co-operat-ing relation to the delivery ends of the chutes 40 and 42 respectively, each of which may be locked non-rotatably to the shaft as by means of a set screw 70. A short spring 71 connecting each dog with the shaft acts to maintain both dogs normally in a backed up position against any suitable stops. Each dog is formed with a pair of jaws 72 providing between them a slot 73 that normally aligns with the delivery end of the roximate chute, so that the coins descen ing t-herethrough may pass partly through the open gates 61 to lodge partly between the jaws, as clearly indicated in Fig. 2.

The dog 68 adjacent the nickel chute is specially provided with an arm 74 from which extends laterally a pin 75 that lies adjacent a latch 76 that is pivoted as at 77 to a suitable bracket carried on the partition plate, a spring 78 pressing against the latch to hold it against the pin 75. This latch, as will be plain from the drawings, is so formed as to limit its own movement away from the partition plate, and carries a pin 79 whose ends are capable of engaging with upper extremities 80 formed on each gate 61 so as to open them. This latch is further provided with acam plate 80? adapted to be engaged by the rock shaft 28, the purpose being to force the latch toward the partition plate with each reciprocation of the carriage. The normal position ot the latch plate, which is indicated in Fig. 2, is such that its lower end lies in the path of upward movement of the rock shaft 28 when the carriage first commences to rise, thus constituting a stop to prevent any but a very limited movement or the a till vation of the carriage. I have also provided means for withdrawing this latch from looking position consisting of an arm 84. secured to the rock shaft and adapted to retract the latch when the rock shaft is properly rotated. The carriage may also be equipped with full stroke mechanism such as is shown in a ratchet 86 secured to the partition plate and adapted to be engaged bya dog 87 mounted upon the carriage in the manner well known to such devices.

Operation.

While the operation of the present machine has already been explained in part, I will now outline the successive movements of the several mechanisms under all the conditions normally encountered.

Toopera' te with one penny:"The bracket support 47 should be set at the topmost notch so that the finger 50 will act to shunt the first penny into the branch chute 42; the dog 69 co-operating with this chute, as well as the other dog'68, should be made tight upon the rock shaft 28. The first penny inserted will partially lodge between the jaws of the dog 69, and when only a slight upward movement has been imparted to the carriage, as by means of'achain which may be conveniently extende'rf'to the exterior of the container, the coin which is partly held beneath the gate 61, will act to turn the dog from the position indicated inv Fig. 2 to that which is shown in Fig. 4, this movement at the same time rocking the shaft 28 sufiiciently to retract both latches 76 and 81 through the medium of the arms 74 and 84 respectively. With rocking of the shaft. the pins 29 are also pro'eeted through the slots 30 to engage wit the adjacent paper, or-other commodity, on the reverse side of the partition late, by which action it is dispensed from t e container as the carriage is raised. The carriage-is now free for elevation through its entire stroke during the execution of which the earn plate 80 is retracted to tally o on both gates for the release of the coin r more than one if necessary) that has been introduced into the machine. It will be noted that this cam plate is of suficien t length to hold both gates open as long as required tor the clean ance of allcoins, this action occurring with each stroke of the a I To operate with two pennies: The bracket support 47 should be set at neat to the topmost notch 55 so that the finger 50 will act to shunt only the second penny into the branch chute'42. With raising of the carriage exactly the same movements take place, with the addition that the upper end 48 of the lever 45 beingengaged by the carriage shield 52, the finger 50 is withdrawn from the chute 39 for a sufiicient interval to permit release of the first coin remaining therewithin. It may be noted here. that if more coins than necessary are dropped into the chute, those in excess of the number required for operation will be shunted into the branch chute 42 to drop into the coin box 41 when the gates 61 are opened with movement of the carriage.

To operate with three or four pennies: The bracket support 47 should beset at the proper notch 55 so that the finger 50 will act to shunt the last penny into the branch chute 42. In all other respects the action of the parts will be the same as already explained.

To operate with one nickel: In this instance, the bracket support 47 may be set at any position, but the nickel dog 68 should be made fast, and the penny dog 69. be made loose, upon the rock shaft 28. When the parts are so adjusted, it will be im ssible for any number of pennies to e ect a rocking. of the shaft 28 and consequent unlocking of the carriage. By the use of a nickel, however, which alone may oo-op-.

erate with the dog 68, the operation of the mechanism is assured in the manner previously stated. In case one or more pennies be also dropped into the chute, they will simply clear through the chutes 39 or 42 into the coin box as the carriage is raised.

To operate with one nickel and one cent: The bracket support 47 should be set at the topmost notch 55 and the nickel dog made loose, and the penny do 69 made fast, upon the rock shaft. 7 When t e proper coins have .been inserted and lodged within their respective jaws, both dogs will turn as the carriage starts upward, the penny dog operating to rotate the rock shaft to thereby retract the latch 81. The other do is also turned, due to the action of the nickel engaged therewith in consequence of which the arm 74: operates to retract the other latch '76, thereby removing all interference to a full movement of the carriage. Both.

coinswill thereafter drop into the coin box as already explained. It will be noted that each coin v operates to *eiicct the release of one latch, and that at least one nickel and one penny are required to efiect the unlocking notion when a sincent ad justmcnt has made in the manner pointed out. I

To operate with a nickel and two or more cents: The same adjustments are required as for sin cents except that the bracket support 47 should be lowered to set the finger 50 properly. In. all other respects the operation of the machine follows the course already outlined.

General observations.

The present machine embodies a convenient amembly of parts all of which are securely mounted on one side of the partition plate, and away from the compartment Within the container where the commodities to be dispensed are. stored. The only adjustments that are ever required are those which aifect the o eration with coins of a selected number an value. lVhen the container is opened up, such adjustments may be made principally from that side of the partition plate where the papers or other commodities are stored. In other words it is not usually necessary to have access to the compartment wherein the mechanism itself is located in order to effect such adjustments.

Another feature of advantage is the use of a single chute which receives coins of different denominations, but which is arranged to separate such coins properly and guide them into branch chutes according to their relative value. It will be noted also that l have utilized two latches, one of which re-- quires for its retraction that the rock shaft he always rocked, and the other of which requires merely that a dog be moved to effect its release, it being immaterial whether the dog be fast or loose on the shaft; and both latches require that coins of the proper number and value be used to effect movement of their respective actuating dogs-as an operation preliminary toraising of the carriage. The various parts of this invention are furthermore conveniently mounted upon the partition plate which is removable from the container when once its cover is opened, so that it is possible to withdraw readily the entire mechanism as a-unit. if it is desired to efl'ect any repairs or adjustments.

While I have described and illustrated a machine that is adapted for operation with coins of difierent denominations, such as pennies and nickels, it is obvious, of course, that changes in the number or proportion ofits parts would render the device suitable for operation with coins of other denominations. Inasmuch as such changes would not require any substantial modification in the operating principle, I have deemed it unnecessary to show other censtructions, but consider that the present disclosure should suflice as an e xemplific'ation of the invention in its preferred form.
