PATENT OFFICE PENNSYLVANIA, ASSIGNORS '10 VENDI CATER,'INC., OF WILLIAHSPORT, PENNSYL- VANIA, A CORPORATION OF PENNSYLVANIA VENDING MACHINE Application filed August 27, 1929,1SeriaLNo. 888,651. Renewed June 23, 1931.

This invention relates to vending machines and pertains more especially to a machine I for vending bottled liquids and has for an object new and improved coin controlled means for controlling the operation of the machine.

In our co-pending application, Ser. No. 340,462, filed February 16, 1929, there is disclosed a machine consisting of a casing within which is rotatably mounted a frame equipped with a plurality of compartments in which are arranged the bottled goods to be sold. The casing'isiprovided with a door 'which when opened permits access to a compartment. Means controlled by the door are.

provided for advancing the frame to the extent of a single compartment upon each opening and closing of the door, these means being so designed that substantial movement of the frame is prevented until the door is virtually closed.

An object of this invention is a new and improved coin releasable locking device for the 'door of such character that the door when closed sufficiently to permit rotation of the frame is locked against re-opening, thereby v preventing the obtaining of access to more than one compartment by the use of a single coin. 1

Other objects, novel features and advantages of this invention will be apparent from the following description and accompanying drawings, wherein I Fig. 1 is a vertical section through a ma chine embodying the invention. 7

Fig. 2 is a section on the line 22 of Fig. 1,.with certain structural details omitted.

Fig. 3 is a partial section on the line 33 of Fig. 1.

Figs. 4 and5 are enlarged sections on the line 4-4 of Fig. 1 with the elements in different positions. v

Fig. 6 is a perspective view of one of the parts making-up the door control mechanism.

Fig. 7 is a section on the line 7 7 of Fig. 3.

'Figs. 8, 9 and 10 are sections taken on the line 8"-8 of Fig. 7 showing diflerentpositions assumed by the various parts, and

Fig. 11 is a fragmentary section on the line 11-11 of Fig. 8.

The machine comprises a cylindrical casing 10 which islf divided into an upper and a lower chamber by a partition 11 the upper chamber bein provided with a removable cover 10a. In the lower chamber there is provided a shelf 11a and a vertical hollow shaft 12 is suitably journalled in the shelf and partition and projects slightly into the upper chamber. At its upper end this shaft 12'ca-rries a circular plate 13 by which is sup ported an annular frame 14 which is made up of a plurality ofsuperposed shelves 15 divided into compartments 15b by radial partitions 15a. Clips 150 may be provided in the compartments to hold the bottles. Within the frame 14 and supported by the plate 13 is provided a tan}; 16 to receive ice or within which may be provided any suitable refrigerating apparatus, the tank 16 having an outlet 17 leading to the hollow shaft 12. The shaft 12 is provided with a drum 18 around which is wound a cable 19 which passes over a pulley 20 and is attached to a weight 21. The weight 21 and cable 19 are effective to cause rotation of the plate 13 when released, the plate normally being held against rotation by means subsequently to be described. A lining 16a of heat insulating material is provided for the upper chamber.

An elongated aperture 'ofsubstantially the same height as the frame 14 is provided in v the wall of the upper chamber and a casing 105 is mounted in said aperture. and has a portion 100 overlying the wall of the casing laterally of the aperture. A door 22 is hinged .to the casing and is provided with an extension 23 (Fig. 4) projecting into the casing 10. Preferably the door 22 is provided with a glass panel 22a through which one vertical row of compartments 15b is visible. The plate 13 is provided on its peripherv with uniformly spaced shoulders 24 which are adapted to be engaged by a pawl 25 pivotally supported by the partition 11 and having an arm 25aengagingthe extension 23 of the door 22. A spring 26 tends to maintain the pawl 25 in position to engage.

a shoulder 24 to prevent rotation of the plate 13 under the influence of the weight 21. A

7 hinged cover 31, which is locked in closed detent 27 is pivotally mounted on the partition 11 and is provided with a socket for the purpose of receiving one of the uniformly spaced pins 28 extending from the lower face of the plate 13. A spring 29 maintains the detent 27 inengagement with the extension 23 of thedoor 22. The shape of the exten sion 23 is such that when the door 22 is opened the pawl 25 is moved out of engagement with the shoulder. 24 and the detent 27 is moved inwardly to receive a pin 28 in its socket, the pin 28 being received in the socket before the pawl 25 is disengaged from the shoulder 24. The socket in the detent 27 is slightly wider than the pin 28, thereby allowing slight movement of the plate 13 after the pawl 25 is disengaged'from the shoulder to prevent re-engagement of the pawl with the pin from which it was just disengaged. The arrangement above described constitutes escapement mechanism mechanism is so designed that it becomes operative before the door 22 is closed suificiently to render the detent 27 inoperative, thereby making it impossible to obtain access to a compartment after the frame has been advanced a step, except by inserting another coin in the coin controlled mechanism. The door 22 is equipped with a closing spring 226.

The door 22 is provided with an extension 30, (Figs. 2 and 3) which overlies the part 100 of the casing 10b, the extension 30 being recessed to form a chamber 30a closed bya Y position by the bolt 31a. The bolt is operable by a key inserted in the tumbler cylinder 316 when the door 22 is open. A hasp 32 is carried by the part 100 of the casing 106 and projects through a slot in the cover 31 i into the chamber 30a. A vertical guide 34 (Figs. 7 to 11) is supported by the front wall of the com artment 30a and within the guide is mounte a slide 35 having a longitudinal bore. A locking bolt 36 having an oblique surface 36a is slidably" mounted in the bore of the slide 35. A vertical guide38 is supported by the guide 34 and in it is slidably mounted a second locking bolt 39 having an oblique surface 39a. A pin 37 passes through the locking bolt and slots 35a in the slide and extends through a slot 34a in the guide 34 and also through a slot 38a in the guide 38 into a socket in the locking bolt39, thus fastening the two bolts together for unitary movement. The two locking bolts are so arranged that both project within the hasp 32 when the door 22 is closed, the upper end of the bolt 36 being in engage- .ment with the cross member of the hasp. A

spring 40 exerts upward pressure on the locking bolt 39. A pin 42 is carried by the slide 35 and extends across the bore of the slide and also projects through a slot 346 in the guide 34. In the lower end of the bore of the slide 35 there is slidably mounted a plug 43 and to the pin 42 and the plug 43 are fastened the ends of a spring 44 while to the pin 42 and the bolt 36 are fastened the ends of aspring 45. The lower end of the bore is inwardly flanged to prevent escape of the plug 43 and the lower end of the slide 35 is cut out at 350 for a purpose which will later become apparent. The relationship of the pin 42, locking bolt36, plug 43 and the springs 44 and 45 is such that when the locking bolt 36 is in its upper or operative position, the plug 43 is held in the bore above the cut-out 350 (Fig. 8). A pin or stud 46 is carried by the part 100 and projects, when the door 22 is closed, through an aperture in the cover 31, an aperture in the guide 34, below the cut-out 35c and under the cup 43. The projecting end of the pin 42 is engageable by shoulders 47 and 47a formed on a rotatable member 48 which is normally held by a spring 49 with the shoulder 47 engaging the pin 42 as shown in Fig. 7. The rotatable member 48 is operable by a handle 50 through the medium of a coin inserted into the recess 50a, the coin being effective to permit operation of the handle 50 in a. manner common to a well-known type of coin release locks. 4 I

Access is normally prevented to alI but the upper shelf of the frame 14 by shields 51 which are slidably mounted in guides 52a projecting inwardly from the wall of the casing 10, Each shield is provided with an aperture 53 which, in one positionof the shields, registers with the door 22. Springs 55 are provided tending to draw the shields into position'to register the apertures with the door 22 but the shields are normally held out gof such position by means" of spring latches 54 mounted on the casing wall and provided with shoulders which engage the edges of the apertures. As described in the co-pending application of McCormick, et al. Ser. No. 340,462, filed February 16, 1929, means are provided to release the shields as the compartments of the shelvesebecor'ne exhausted.

The operation of the device as described up to this point is as follows: Assume that the compartments of the various shelves have been filled with bottles and that the compartments equipped with the flaps. 56 are in register with the door 22. The shields 51' are held in retracted position by the latches 54 so that only the top compartmentwill be accessible when the door is opened. The weight and 39 are the position shown in Fig. 8. Assume now that a coin is inserted through theslot 50a and the handle 50 is turned to bring the shoulder 47a intoengagenient with the pin 42. By virtue-of such engagement, the slide 35 is pulled downwardly and asthe upper end of the slot 35a .in the slide engages the pin 41, the bolts 36 and 39 are drawn down out of the way of the hasp so that the door may be opened (Fig. 9) Opening of the door removes the pawl from ths shoulder 24 and brings the detent 27 into operative position, thereby permitting slight rotation of the table '13 (Fig. 5). The bottle may now be removed from the registering compartment after which the door is closed, either manually or by its spring, the locking bolts being moved downwardly by engagement of their oblique surfaces with the 'crossmember of its hasp 32, thereby rendering the detent 29 inoperative and permitting the plate 13 to advance until the pawl 25 engages the next shoulder 24, thereby bringing a new compartment into register with the door 22. v

The plate 13 is released by the detent 27 just before the door 22 is completelyclosed and means are provided for preventing advantage being taken of this fact to obtain more than one bottle with a single coin.- When the pin 42 is moved downwardly the H spring 44 is compressed and presses the plug "43 against the pin 46-(Fig. 9). As the door is opened the plug 43- moves out of contact with the stud 46 and is then pressed downward into theposition shown in Fig. 10, its downwardmovement being limited by the flanges at the bottom of the slide 35. The

plug 43 will remain in this position until the.

pin 42 is returned to normal position by the shoulder 47, and in this position it is im possible to close the door sufiiciently to release the detent 27 since the stud 46 will engage the plug 43. In order for the door to close, under such circumstances, sufiiciently to disengage the detent 27 it is necessary first to release the handle so that the member 48 may be returned to the position shown in Fig. 8 by the spring 49 whereupon the pin- 42 will be returned by the shoulder 47 to the position shown in Fig. 8 and the plug 43 will bei returned to the position shown in the gure.

The bolts 35 and 39 are thereupon projected by their springs into locking. position and turning of the handle 50 is prevented since the coin was dropped from the slot 50d when the handle 50 reached the limit of its rotatlon. Closure of the door suflicicntly to render the'detent 27 inoperative, places the bolt 39 in engagement with the hasp 32 and prevents and having a refund for such bottles. An

aperture is provided in the wall of the lower chamber and a cylindrical tray is-supported therein. The cover 61 is arranged at the upper part of the aperture and the ends of a shaft 62' are journaled in the tray and cover. A collar 63 is keyed to the shaft 62 and is provided with a handle 64 which projccts through a slot in the lateral wall of the tray 60. A carrier 65 is also keyed to the shaft and rests upon the collar 63. A helical spring 66 has one end attached to the tray 60 and the other end of the lever 64 normally tends to hold. the bottle carrier in position to receive the bottle. By means of this mechanism a bottle is presentedto the refunding mechanism (not shown) and is discharged onto the shelf 84 having a sloping portion which overlies a receptacle 85 having a sloping bottom 86. The remaining mechanism of the bottle refunding mechanism and the operation thereof is fully described in the copending application of McCormick, et al. Ser. No. 340,462, filed Feb. 16, 1929.

The coin used to release the locking mechanism is dropped into a chute 90 in which it is held in back of a magnifying glass 91 until the machine is again operated (Fig. 7 The coins with which the machine has been operated are thus temporarily displayed and make it possible for an observer easily to discover whether a slug has been used instead of a coin. A pivoted arm 93 extends into the chute 90 and acts as a stop to locate the coin in front of the glass. This arm is pressed toward a stop pin 93a by a spring 935. A pivotally mounted lever 94 is provided with a lip 94a which engages'a lip 930 provided on the arm 93. A spring 95 tends to hold the lever 94 in the position shown in Fig. 8, while a stud 96 is provided on the rotating member 48 to engage the upper end of the lever 94. The operation of this mechanism is as follows: The coin'c which was last used to release the locking mechanism is supportedin the chute in front of the magnifying glass by the arm 93'. As the member 48 is rotated, the stud 96 engages the upper end of the lever 94 and moves the same slightly. By reason of the engagement of the lips 930 and 94a the arm 93 is moved against the action of the spring 936 sufficient to permit the coin 0 to drop. The stud 96 moves out of engagement with the upper end of the lever 94 allowing it to be returned to'normalposition. by the spring 95 which permits the spring 936 to return the arm 93 into position to be engaged by the coin by means of which the lock has just been released. As the rotating member48 is.returned to normal position, the stud 96 again 7 trips the lever 94, but this has no efl'ect on the arm 93 as the lips 930 and 94a merely move away from each other and then back into contact. 7

It is oi pourse understood that various structural modifications may be made in the device above described, without in any Way departing from the spirit of the invention as ient member.
