Application led February 3, 1898.

To all whomA t may concern: Be it known that we, ALEXANDER J AEGE and OTTO JAEGER, citizens of' the United States, residing at Philadelphia, in the county of Philadelphia'and State of Pennsylvania, have invented a certain new and useful Improvement in Automatic Vending-Machines,

of which the following is a specification.

Our present invention relates to a newand useful improvement in automatic vendingmachines, and has for its-object to provide a coin-detector of such construction as to rendisks to the money-drawer of the machine, even though said disks be of a size which exactly correspond with the coin intended to be used in operating the mechanism of the machine, and to discharge these disks,which have been detected, to one side of the chute and outside of the trough by the insertion of the next coin or disk also, to prevent the moneyor other material.

A further object of our invention is to provide for the automatic discharge of the articles being vended, thus avoiding the necessity of having to operate a lever or pull for the ejection of said articles, and a still further object of our invention is to generally improvey the construction and arrangement of devices 0f this description.

Vith these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this Specification, in which- Figure l is a vertical section, taken through the center of one of the holders, showing the art-icles therein resting upon the trip-wheels and the mechanism in its normal position ready to be actuated by a coin so as to veject the lowest of the articles in the holder; Fig.

In carrying out our invention as here embodied A represents the casing, which is preferably made of wood and of any suitable design to holdthe operating parts of the device and the material to be vended, and within this case is located the holders B, which may be in any number to suit the :requirement of the particular use to which the machine is to be put, and these holders are so constructed as to receive and hold the articles O, which are to be vended in small packages. Vithin the lower portion of the machine are placed a series of trip mechanisms D, which correspond in number to the numberof holders, and the frame of these mechanisms support the lower ends of the holders by means of clips E, formed upon the back of the holders, engaging with the cross-pins F, while the upper ends of the holders are held in place by IOO the turirbutton G, thus facilitating the removal of these holders when occasion may require, as will be readily understood.

Each of the trip mechanisms consists of a shaft H, which is journaled in the side plates of the frame and has secured thereon two escapementwheels I, each having four teeth or notches therein. These escapement-wheels are so located relative to the lower ends of the holders that the articles contained within the holders rest upon one of the teeth of each of the wheels, thus preventing the downward movement of the articles so long as the wheels remain in the position shown in Figs. l and 7. These wheels are held in this position by the trip-lever J, which is pivoted at K and has formed thereon the escapement-teeth L and L', a spring M normally holding the escapement-tooth L in engagement with one of the teeth of the escapement-wheel, so that to trip these escapement-wheels it is only necessary to swing the escapement-lever so as to carry the escapcment-teeth upward, causing the tooth L to pass out of engagement with the teeth of the escapement-wheel, while the tooth L enters into engagement with another tooth of this holder and acts after the manner of a cam to insure the initial movement of the escapement-wheels, and this, in connecton with the weight of the articles within the holder, which, as clearly shown, is beyond the center of the shaft Il, will cause the escapement-whecls to revolve one step or a dis-- tance equal to one-half of one of the teeth of the escapement-wheels, thereby bringing the' mechanism to the position shown in Fig. 8. New when the escapementdever is released the spring lll will return to its normal position and in so doing again permit the escapement'wheels to revolve another step, which will be equal to the half of a tooth, and consequently these two steps will have equaled the movement of one tooth and permitted the last package in the holder to drop therefrom. This of course will cause the articles remaining in the chute to fall a distance' equal to the package removed and the next lowest package to rest upon the teeth of the escapement-wheels, as before described. To prevent a retrograde movement of the cscapement-wheels, a pawl N is so pivoted as to engage with the teeth thereof at the proper junction, and thus hold the wheels while the escapement is not acting thereon.

O is a stop-plate secured to the frame of each of the escapement mechanisms and so located as to limit the movement of the escapement-lever in both directions, and the escapement-lever has an extension P projecting rearward therefrom, the outer portion of which is turned iat to afford a suitable surface against which the coin may strike when dropping from the chute Q.

A bracket R is secured to the back board of the casing and serves to support that portion of the mechanism which receives the coin from the slot, sizes and tests the same before permitting it to ,pass to the chute, and ejects those coins and imitations of coins or other articles which are not up to standard, it being understood that there are as many brackets and mechanisms carried thereby as there are holders. An escutcheon R is attached to the front portion of the bracket and has a slot R2 therein for the insertion of the coin, and immediately back of this escutcheon is journaled a rod S, in which are formed longitudinal grooves S, giving this rod in crosssection the appearance of a pinion. Each of the grooves in the rod may serve as a guide for the coin after entering the slot, and as the rod is set upon an incline the tendency of the coin when entering the top groove is to roll rearward, and if it be of standard metal it will pass to the chute Q and, dropping downward, fall upon the rear end of the lever P, depressing the same and bringing about the movement of the escapement-wheels,as before set forth, to extract one of the articles contained within the holder.

The chute Q is set upon an angle, and the lower side thereof is cut away, so as to just afford a bearing for a coin of standard size, so that should the coin or imitation be of less than standard size it will be dropped from the chute in its downward passage and be caught in the pan S2. A horseshoeunagnet T is secured to the plate T', which latter is pivoted within a portion of the bracket, so as to swing sidewise in the direction of the arrow marked adjacent thereto, and one pole of this magnet normally lies just to one side of the path of travel of the coin, as clearly indicated in Fig. 3, so that the coin in its passage from the slot to the chute must come in close proximity to this pole, and should an iron or steel disk be inserted within the slot for the purpose of operating the machine when reachin this pole it will be attracted thereby and prevented from gaining access to the chute. It is obvious that while the spurious coins or other articles thus stand in the passage-way between the slot and the chute a standard coin cannot reach the chute to operate the machine, so that it is essential that this spurious coin be ejected from the passageway, and this we accomplish in the following manner:

An arm U is secu red to the plate T and so bent as to form a push-off or ejector U', which normally lies to one side of the passage-way through which the coin passes, and this arm also has pvoted thereto a pawl U2, the nose of which engages with the grooves in the rod S', so that it is only necessary to force the plate T' to one side in the direction of the arrow to swing the magnet in this direction and at the same time force the ejector U against the spurious coin and likewise operate the pawl U2 to revolve the rod one step, which will carry the lower portion of the coin or other articles sidewise, and a strip U3 will prevent the upper portion of the spurious coin following the pole of the magnet, thus freeing said coin and permitting it to drop IIO into the pan S2, as clearly shown in Fig. 4. The slot in the escutcheon is of such a size as to just admit a coin of the proper dimension, so that unless the coin is of standard size or under it cannot be inserted, whereas should it be under standard size it will drop from the chute, as before set forth, and should it be of iron or steel it will be ejected before reaching the chute, thus avoiding the possibility of the machine being operated by spurious or imitation of coin.

The ejector is operated upon the insertion of each coin by means of a bar V, which is secured to the plate T and has formed therewith an arm V', which extends downward and into contact with the lever V2, the latter being pivoted at V3 and lying partially across the slot, so that when inserting a coin this lever must be forced sidewise and in turn force the arm V sidewise and bring about the movement of the plate T', which actuates the ejector mechanism, as before set forth. This will eject the spurious coin or other articles and leave the passage clear for the next coin to pass to the chute.

Then the rod S is revolved one step, the next groove comes into position and acts as a guideway until again revolved, and this is of considerable importance in that should particles of grit or foreign matter become lodged in the groove being used as a guideway it will fall therefrom when revolved, so that when this groove again comes into position it will be free from the obstruction of the passage of the coin. A pawl V4 is arranged to engage with the grooves in the rod S and prevents a retrograde movement thereof.

lVhen one of the packages has been withdrawn from the holder, it will in its downward movement come in contact with the gate W, the latter being so pivoted and weighted as to normally remain closed, as shown in Figs. l and l0, and when this package comes in contact therewith the gate will be swung open and the package permitted to continue its downward movement until reaching the tray WV', the rear portion of said tray being inclined, so as to slide the package forward into plain view of the customer. After the package has passed the gate the latter will again close,and thus form an effective obstacle for the insertion of a wire or other implement for the unauthorized operation of the trip mechanism which would tend to withdraw the packages.

From this description it is obvious that the would-be purchaser has only to insert the coin within the slot to set in operation the proper mechanism for the extraction of a package from either of the holders, and no further manipulation of the machine is necessary, since the entire operations are performed automatically and the package dropped into the tray in plain view, from which it may be removed.

A tray W is secured between the sides of the casing by suit-able screws, and beneath the front portion thereof is fitted a plate NVQ, as shown in Fig. l2, said plate having a forked end a, which iits around a pin b, so that thev lease the plate, and thus the money-drawer f 8o cannot be tampered with. The face-plate g is held in place by its lower edges entering into engagement with the notches formed in the tray, as indicated at hv, and the engagement of the hooks t' with the lugs j, and nally the casingis closed by the front board 7e, which has a groove in its lower edge adapted to fit over the bead Z, formed upon the upper edge of the face-plate, and a suitable lockis located at m for securing the upper portion of this front board. This arrangement permits of ready access to any portion of the machine, and especially to the holders and to the moneydrawer. The pan for spurions coins rests upon the ledge n, its front edge being supported by the hooks p, and is thereafter easily removed when occasion requires.

Of course we do not wish to be limited to the exact details of construction here shown, as these may be varied to some extent without departing from the spirit of our invention.
