C. Olsen wherein the contents of: bottles are emptied and delivered to the cus has been ?lled. It is important that doors of this type be operated by the Vending mechanism in properly timed relation with the rest of ‘the steps in the vending process. It is'furtherjim portant that such door be movable to the ‘open A , elements employed ‘for transmitting force from the vending mechanism to the delivery door for tomer in individual cups; it is desirable to have a door normally closing the opening. through 10: which the customer may grasp the ‘cup after it i Fig. 5 is an edge elevational view of a pulley partly shown in section and forming one of‘ the goods, or in'machines of the character illustrated operating the latter. - I In the drawings, the numeral 10 designates a cabinet fo'rhousing merchandise, and apparatus for vending the same-only such portions of the vending mechanism being shown as will be help ful in describing its relation to the structure com : prising the instant invention. ‘ A pair of loading doors l2 are joined by hinges Mtocabinet l0 and one of these doors is pro- ' position ‘only by the vending mechanism to which . vided with afdelivery opening I6 having guide it‘ is operably connected. Moreover, the device grooves“! wherein iismslidavbly mounted a xdoor for preventing unauthorized opening of the door should be capable of functioning throughout the 20 2i). A'recep'tacle 22 attached to the rear face of door l2 in communication with that portion entire distance between‘ the opening and closing of opening I6 normally closed by delivery, door limits of the door movement. Accordingly, it is 20, is formed with a side port 24 through which a the primary object of this invention to provide cup is delivered prior to receiving the contents a delivery door for a vending machine, which door is operably connected to the vending mecha 25 of a bottle or the like. The construction of door 20 per se is relatively nism in properly timed relation therewith. unimportant although a transparent panel 26 It is a further aim of the invention to embody should preferably be provided therein through locking members in a door structure for normally which a customer may view the receptacle and its preventing opening of the door, but which are contents located behind the door. automatically released when force from the vend Secured to the upper edge of door 20 are a pair ing mechanism is exerted on the door for open ing the same. _ ' Ayet further object of this invention is the provision of a delivery door within a loading door,‘ and of structure for operably connecting the delivery door with the vending mechanism in a manner to substantially eliminate displace ment of the delivery door relative to its opening when the loading door is opened or closed. These and other objects of the invention which of angle members 28 having upstanding leg portions 39] in spaced apart relation for receiv ingtherebetween a pair of dogs or looking mem , bers 32, pivotally mounted on bolts 34 extended transversely through the legs and dogs. As clearly shown in Fig. 2, each of dogs 32 is provided with a cam face 36 and the location of the pivoting point of the dog is such that with structure shown in the accompanying draw upward movement of the door will tend to force the cam faces into tighter‘engagement with the groove I8 of the door opening.

This bar in turn is reciprocated by the movement of a chain 56 which is actuated by a reversible motor (not shown). A shaft 58 journalled in suitable bear ing openings in walls 69 and 62 of the cabinet carries pulleys 64 and 6B ?xed thereon adjacent its opposite ends. Wound on the larger pulley claimed as new and desired to be secured by Let ters Patent is: 1. In a vending machine cabinet having a load ing door hinged to the cabinet and provided with a delivery door opening, a delivery door nor mally closing said opening; a pair of locking members on the delivery door engageable with the loading door for normally preventing opening of the delivery door; a Y-shaped flexible member 6/4‘ is a cable section 68 having its one end fixed 10 having the ends of the branches connected to said locking members and its stem extending to to the pulley and its other end secured to bar 54. Cable 59, leading upwardly from the delivery a point within the cabinet for releasing said mem bers and opening the delivery door in response to force applied to the stem of the ?exible member door 20, is run over a sheave 10 in door I2, over pulleys ‘l2 and 14 carried by brackets 16 and 18 15 in the cabinet; and a pair of pulleys respectively , respectively mounted on door l2 and on the cabié. mounted on the loading door and in the cabinet in substantially‘contiguous relation with the axis of the loading door hinge for guiding said ?exi ble member and for substantially preventing anchored in any suitable manner. ‘ The positions of pulleys ‘l2 and 14 with respect 20 movement of the delivery door relative to its to hinge It is relatively important and, as will be opening whenthe loading door is opened and net, and ?nally over a sheave 8c in the cabinet, to the smaller pulley $6, whereon it is wound and clear from Fig. 4 of the drawings, they are lo closed. , cated as closely as practical to the hinge in order 2. A vending machine cabinet having a loading that opening of the loading door will not mate door hinged to the cabinet and provided with a rially alter the position of delivery door 20 in its 25 delivery door opening, a delivery door normally guide grooves. closing said opening; a locking member on the delivery door engageable with the loading door Since the distance of travel of bar 54 is less for normally preventing opening of said delivery than required to move door 29 to fully opened po door; a ?exible member having one end con sition, the ratio of travel of the door to that of the bar is increased through the employment of 30 nected to the locking member and its other end extending to a point within the cabinet for re pulleys 64 and 66 of different diameters. leasing said member upon application’ of a pull As will be apparent, the door 20 may, if de upon the end of the member in the cabinet; and sired, be mounted in a stationary wall of the cab a pair of guide members for the ?exible member inet, in which case the procedure of _ operably connecting the door with the vending mechanism 35 mounted respectively on the loading door and the cabinet contiguous to the axis of the hinges of the would be simpli?ed. Other modi?cations might loading door in order to prevent substantial be made without departing from the spirit of the movement of the delivery door relative to its invention, and it is desired therefore, to be lim opening when the loading door is opened or ited only by the scope of the appended claims.
