3 Claims.

, This invention relates to vending machines and particularly to a machine of this'ola'ss which is adapted to the sale of cylindrical or roll-shaped packages, such as mint' rolls and the like.

An object of the invention is to provide in a machine of this class an improved type of vending mechanism which is particularly well adapted to the delivery of roll-shaped packages.

Another object of the invention is to provide a housing structure for the vending mechanism which may be opened in such a manner as to facilitate re-fllling of the machine and the removal of coins deposited therein.

Further objects and advantages of 'the invention will be apparent as I proceed with my speciilcation, which, taken in conjunction with the accompanying drawings, discloses ya preferred embodimentthereof.

Referring to the drawings:

Fig. 1 is a broken front view of the vending machine;

Fig. 2 is a side elevational view of the machine, parts of the housing being broken away to show the internal structure;

Fig. 3 is a section showing the vending mechanism, the section being taken on the line 3 3 of Fig. 2;

Fig. 4 is a section showing the .vending mech- Y a housing consisting of a front cover plate I0, a

back plate I the opposite ends of which are bent outwardly to form a top Wall I2 and a bottom wall I3, and side walls I4, which, together with the front cover plate I and the .back plate Il, formv corresponding edges of the top wall 2 and the the line (ci. 31a- 48) side walls |4. A pair of strap links I6, extending between points of connection with the back plate I and a marginal edge of the cover plate I0, limits the amount ofopening swing permitted of said cover p1ate. A lock I1 is attached to the upperr end of the cover plate I0 and is provided with a bolt |'|a which engages the outer marginal edge of the top wall I2 to hold the cover plate in closed position. The housing is attached to a suitable. supporting panel I8 by means of screws I9 which extend through the back plate` into the body of the panel. The entire housing may be-stamped from sheet metal, the side Walls I4 beingvsecured to the walls I2, and |3fby welding or by suitable bolt connections.

Referring particularly to Figs. 2-5, the vending mechanism in the embodiment shown comprises: a pair of vertically disposed magazine holders 2| which serve as storage chambers for the mint rolls; a mint delivery mechanism located at the bottom of the holders 2|and designated generally by the numeral 22;` and a discharge chute 23 for guiding the rolls from the delivery mechanism to a discharge port 24 in the cover plate I0. As hereinafter explained, the,

yvending mechanism is operated by a coin device 25 carried on the cover plate Ill and operatively connected with the delivery mechanism 22.

Referring to Figs. and 7, the magazinaholders 2| are channel-shaped and include back walls 26, side walls 2l, and flanges 28 which are bent inwardly from the opposite side walls 21. 'I'he holders are open at each end and are supported atl/their upper ends by bracket arms 29 carried by the cover plate I 0, and at their lower ends by U-ishaped bracket plates 3| and 32, which extend Y between the holders and engage the opposite side walls to hold them in parallel spaced-apart relation. The plates 3| and 32 may be joined together and supported as a single unit on the cover platey I0 by a spacer 33 (Fig. 4). They magazine holders are thus rigidly supported on the cover plate I0 and are freeto swing with the plate into the open position indicated by the dotted lines in Fig. 2. In this position the machine may be easily re-lled by introducing additional rolls intov the upper open ends of the holders.

Referring particularly to 3-6, the delivery mechanism 22, which is designed to deliver mint rolls alternately first from one and then from the other of the holders 2|, consists of a pair of part- cylindrical cups 34 and 35 which are pivotally supported in horizontal position below the magazine holders 2| by means of shoulder screws 3D, carried by lugs 36 and 31, which are struck from the body portion of the bracket plates 3| and 32, respectively. The cups 34 and 35 are positioned so that the open face of one is displaced approximately 180 degrees from that of the other, and, as wirll presently appear, are arranged to be alternately turned to separate a mint roll 38 first from one and then from the other of the stacks of rolls in the holders 2|.

Referring to Figs. 3 and 4, the oscillation of the cups 34 and 35 is eifected by the coin control means indicated generally by the numeral 25. This mechanism is here shown only generally, it being shown in detail in my co-pending application, Serial No. 516,056 filed February 16, i931 which has eventuated into U. S. Letters Patent 1,869,616 of Aug. 2, 1932. The mechanism 25% includes an operating handle 38 which projects from the cover plate I8, a plate 39 secured by bolts 4| to the cover plate I0, and a coin-detecting magazine 42 supported on the plate 39. A spur gear 43 turns with the handle 38 on the introduction of a proper coin in a coin slot 44, and a second spur gear 45, supported on the plate 39, meshes with the gear 43 and is arranged to make a half turn for each complete revolution of the handle 38 and gear 43. The gear 45 is operatively connected with the cups 34 and 35 through a bell crank lever 46, which is pivoted at 4'| to a lug on the bracket plate 3|, anda link 48 connected at one end to a pin 49 carried by the long arm of the lever 46 and at the other end to a stud 5| mounted eccentrically on the gear 45. The short arm of the bell crank lever 46 connects with a link 52, which, in turn, is connected at 53 to one of a pair of arms 54 and 55 carried by the cups 34 and 35, respectively. A link 56 is connected at 51 to the arm 54 and at 58 to the arm 55.

Referring to Figs. 3 and 6, it will be apparent that as the spur-gear 45 is operated by turning of the handle 38 the lever 48 will move downwardly until the point of pivotal'connection 49 has shifted to the-point 59. During this cycle of movement, which is eiected by one complete turn of the coin-controlled handle`38, the cups 34 and35 will be turned from the position shown by the solid lines in Figs. 3 and 6 to the position shown by the dotted lines in Fig. 6, causing the cup 35 to discharge a mint roll 38 and at the same time turning the cup 34 to receive a mint roll 38 from the adjacent magazine 2|. Upon an additional revolution of the handle 38 the lever 48 will be raised to again assume the posi-- tion shown in Fig. 3, during which interval the cup 34 will discharge a'mint roll 38 and the cup 35 will be turned to receive another mint roll. Each of the cups thus completes a cycle of receiving and discharging a roll from its corresponding holder for two successive coin actuations of the machine. The discharged rolls fall into the chute 23, from which they may be removed from the opening 24 in the cover plate I0.

The front cover plate l may be provided with a window 6| for viewing the coin which has been used in the last preceding operation of the machine, and the plate may also be provided with a metal frame 62 for holding a card giving directions for the operation of the machine. Coins which have been accepted for the purchase of the mint rolls are collected in a container 63 which rests on the bottom wall I3 of the housing.

The construction embodying the feature ofthe hingedly-mounted cover plate, having the vending mechanism mounted thereon, `is exceedingly practical inasmuch as it Agreatly facilitates the re-illing of the machine and the removal of coins which have been deposited in the purchase of the mints. This feature also permits of the mounting of the housing by means of screws inserted through the back plate which are protected against removal after the cover has been closed. 'I'he delivery mechanism is always positive in its action and is of a type capable of severe and extended use without 4danger of jambingor breaking. i

'Ihe foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.

What I regard as new and desire to secure by Letters Patent is:
