FIGURE 10 is a section taken along line 10-10 of FIGURE 5.
A latching unit forming the subject of this invention is shown in the drawings as applied to a cabinet for the vending of articles such as newspapers. The cabinet is mainly of sheet metal construction and has a front opening defined by the front edges of a pair of opposed upright side walls 10 and 11, opposed top and bottom walls 12 and 13 respectively, and a rear or back wall 14 from which said walls 10, 11, 12 and 13 extend for- 'ice wardly. A lid or door 15, joined by a hinge 16 to the upright side walls 10, is operative to swing between opened and closed positions across said front opening of the cabinet. The door is providedv with a suitable handle 15a.
The area within the cabinet is adapted to be occupied by a stack of newspapers 17 or the like, except for a portion between the side wall 11 and an upright partition wall 18 opposite wall 11 to provide a compartment separate from the newspaper containing area of the cabinet. Access to the compartment is controlled by an auxiliary door 19 hinged to the bottom wall 13 of the cabinet so as to swing between an upright position in closing relation to the compartment and an outwardly and downwardly extending position when the cabinet door 15 is in open position.
A locking finger 23 rigidly fixed to and projecting inwardly from the inner face of the cabinet door 15 has entry to the area within the compartment when the door 15 is closed via an opening 24 provided in the lower portion of the compartment door 19. When thus projected into the compartment, a hook 25 at the in-' ner end of the finger occupies a position belowand in substantially vertically aligned relation with a mounting bracket 26 carried by the compartment door 19 and at a distance short of a stationary catch 27 provided along the lower edge of bracket 26. The bracket 26 presents opposite upright faces along the plane with which the finger 23 and the hook 25 have vertical alignment. Suitable screw fastenings 28 fixed to and projecting from the surface of this door 19 facing the bracket 26 fit holes formed in wings 29 extending angularly from the edge of the bracket 26 facing the door 19 which allows for ready attachment and removal of the bracket to and from a securely fastened position on the door 19. Also attached to the compartment door 19 so as to occupy upright planes in symmetrical relation astri-de the area occupied by the finger 2 3 and hook .25 when the door '15 is in closed position are a pair of arms 30. The inwardly projecting ends of the arms 30 extend beyond the hook 25 in a direction away from the door 19 and such ends are secured to the lower ends of stabilizer arms "39a suitably fixed to and diverging downwardly from opposite face of the bracket 26.
Looking means effective to establish a latched connection between the hook 25 and stationary catch 27 on bracket 26 includes a control member supported forverin spaced apart parallel relation via webs 34 and along the upper edges of the wings and spaced apart length- Wise of said wings so as to provide an open area between said webs. The shaft 31 projects through transversely aligned slots 36 provided approximately midway of the length of the wings 32 and 33 and of elongated dimension lengthwise of said wings. Coil springs 37 connected at one end to said wings 32 and 33 and connected at the other end to a pair of arms 26a forming a downward extension of the bracket in a direction away from the area occupied by the control member act to normally urge the control member in the direction of the catch 27. A flange 32a extending inwardly from the lower edge of one of the arms 30 defines a shoulder with which the wing 32 of the control member has downward engagement to limit rocking movement of the control member in the direction of the catch 27 while the control member is thus tensioned by the springs 37 to occupy an extended position wherein the ends of the slots 36 farthest from the catch 27 have engagement with the shaft 31. While the control member is thus positioned at the limit of its movement relative to shaft 31 in the direction of the catch 27 an edge portion 38 of the web 35 facing toward the web 34 is in such oppositely facing relation to the catch 27 as to have latching engagement with the catch 27 along said edge portion 38 when the control member is subjected to a force seeking to move the control member in a direction away from the catch 27 toward the shaft 31. Each wing 32 and 33 of the control member is sloted as at 39 to provide transversely aligned guideways in which a roller 40 is supported for movement between upper and lower positions and biased by gravity toward a lower position. While in such lower position the roller 40 is efiectiv to obstruct movement of the hook 25 in the direction of opening movement of the door 15 whereby the door 15 is securely retained in closed position While the control member is in latched engagement with the catch 27.
A first channel member 41 having hinged connection with the bracket along one upright face thereof via a pair of arms 42 pivotally connected in coaxial relation to upper and lower portions of a flange 26b of the bracket 26, and a second channel member 43 similarly connected via arms 44 pivotally joined in coaxial relation to upper and lower portions of a flange 26c. of the bracket 26 along the opposite face of said bracket, each cooperate with the face of the bracket opposite thereto to define a coin chute. The chute defined by channel member 41 has an entrance portion in registry with a coin receiving slot 45 in the compartment door 19 and a slot 46 in a panel 47 carried by the cabinet door 15 in alignment with slot 45. The chute defined by channel member 43 has an entrance portion likewise in registry with a coin receiving slot 48 in compartment door 19 and a slot 49 in panel 47 in alignment with slot 48. Each of said chutes extends downwardly from its entrance portion along a line leading directly to the area occupied by the web- 35 when the control memher is in a position to have latching engagement with the catch 27 on the bracket 26. Accordingly, the outlet end of the chute formed by channel member 41 is located opposite a ramp 50 defined by a relatively narrow flange along an upper edge of wing 32 of the control member which merges with the web 35. The chute formed by channel member 43 on the opposite face of bracket 26 has its outlet opposite a similar ramp 51 defined by a flange along the upper edge of wing 33 of the control member with which the web 35 also merges. It will be noted that each ram- p 50 and 51 as well as web 35 presents a concavely curved surface about an axis parallel to the bearing shaft 31 on which the control member is supported. Accordingly, a coin deposited in the chute having its outlet end opposite ramp 50 will come to rest edgewise against the curved surface of ramp 50, as shown in FIG.-5. A coin deposited in the chute having its outlet end opposite ramp 51 will likewise come to rest edgewise against the curved surface of ramp 51.
Each coin chute thus defined by the channel member 41 and the channel member 43 is slotted to provide a clearway for the entry of a pivoted coin trapping pawl 52 which is normally biased by gravity to occupy a position in the path of a coin travelling therein but is rockable away from an obstructing posit-ion to clear the path of the coin so as to permit downward travel of the coin until it encounters the ramp with which the chute containing said coin is associated. Thus, while a coin within either chute is at rest on the ramp associated therewith, the pawl 52 in the path of said coin is effective to immobilize the coin against upward travel. The coin While thereby fixed against upward travel is operative to cause the ramp engaged thereby to be cammed and rocked downwardly against the force of the spring 37 when the hook 25 applies pulling force on the roller 40 to move the control member away from the catch 27 incident to opening movement of the cabinet door 15. As the control member is thereby moved toward its limit of travel in a direction away from the catch 27 under continued pulling force applied on the roller so by the hook 25, the coin drops by gravity from the outlet end of the chute to the floor of the compartment therebelow.
As shown in FIG. 6 as the web is dragged along the lower surface of the bracket in the direction of the bearing shaft 31, the control member is caused to tilt upwardly in the direction of the hook 25 which allows the 'roller to be lifted clear of the book 25 and thereby release the hook to allow the door 15 to be fully opened.
The provision of a pair of coin chutes as described herein makes it possible to accommodate coins of a selected denomination in one of the chutes at variance with the selected denomination of coins for use in the other chute. The coin trapping pawls 52 are also mounted for adjustment to selected positions defined by notches 52a in the flanges 26b and 260 of the bracket 26 whereby immobilization of a coin may be established at selected locations along the coin chute containing such coin according to the number and denomination of coins which it is required to deposit in the chute to permit opening of the cabinet door.
The hinge arms 42 and 44 connecting the channel members 41 and 43 respectively to the mounting bracket 26 provide for swinging movement of each channel member toward and away from the face of the bracket opposite thereto along the lower edges of the channel member. A spring 54 connecting said channel members is' effective to normally bias the channel members into operative chute defining engagement with the face of the bracket opposite thereto. A coin located in the chute defined by either of said channel members is thus caused to fall from the chute and thereby dumped into a coin return receptable 55 for retrieval by the person depositing the coin when the channel member is swung away from the face of the bracket 26 opposite thereto. Such movement of the channel members to so discharge a return a coin is effected through operation of a pivoted lever 56 which is actuated in response to depression of a plunger 57 accessible from a position outside the cabinet as shown in FIG. 5.
The control member is releasably latched against return movement to a position of latched engagement with the catch 27 by a latching lever 58 pivotally connected at 58a to the bracket 24 for vertical rocking movement between raised and lowered positions and biased by gravity or other suitable means toward a lowered position effective to engage a catch 59 on the control member. It will be noted from FIG. 6 that the catch 59 is defined by an edge portion of a horizontally extending flange 60 projecting from the upper edge of wing 32 of the control member and that the latching lever 58 has downward bearing engagement with said flange 60 pending completion of travel of the control member in a direction away from catch 27. While the control member is thereby locked against movement toward the catch 27, an arm 61 forming a branch of the lever 58 occupies a position between the wings of the control member within an area into which the hook 25 projects when the cabinet door 15 is closed. Thus, while the cabinet door 15 is about to arrive in closed position from an open position, the impact of the hook 25 against the arm 61 is effective to rotate the latching lever 58 out of a position of-engagement with the catch 59 whereupon the springs 37 act to move the control member toward a position wherein the catch 27 is effective to have latched engagement with the edge 38 of the web 35.
A closure arm 62 having one end thereof pivotally connected to the upper edge of door 15 and extending therefrom for movement in unison with swinging movement of the door 15 in a plane in close downwardly spaced relation to the top wall 12 of the cabinet is yieldably stressed to occupy a position within the confines of the cabinet and thus normally urge the door 15 to remain in closed position. Such stress is applied by a spring mem- 1 her which is bowed in a plane parallel to the top wall 12 to provide an end portion 63 which is fixed to a lip 64 along the front edge of the top wall 12 of the cabinet and a second end portion 65 which is pivotally connected to the inner end of arm 62. A similar closure arm 66 connected to the bottom edge of door for swinging movement coaxialy with arm 62 in a plane in close proximity to the bottom wall 13 is similarly stressed to occupy a position within the confines of the cabinet via a spring member having an end portion 67 which is fixed to a lip 68 along the -front edge of the bottom wall 13 of the cabinet and a second end portion 69 pivotally joined to the inner end of arm 66.. A panel 70 suitably fastened in downwardly spaced parallel relation to the top wall 12 of the cabinet encloses the area containing the arm 62 and its associated spring while a similar panel 71 suitably fastened in upwardly spaced parallel relation to the bottom wall 13 of the cabinet encloses the area containing the arm 66 and its associated spring.
It will be understood that on movement of the cabinet door 15 from an opened to a closed position, the roller 40 carried by the control member, will be forced upwardly by the leading bevelled edge of the hook so as to allow the book 25 to pass thereunder and thereupon have re-engagement with the roller to again securely lock the door 15 in closed position when the web 35 of the control member is latched engagement with the catch 27.
The door is prevented from swinging beyond a predetermined opened position by means of a stop 62a on the arm 62, which, as shown in dotted lines in FIG. 2, engages the lip 64 along opposite sides of a guide opening 64a provided in the lip 64 in which the arm 62 is slidable incident to opening and closing movements of the door 15. A plunger 62b mounted on the panel 70 between locking and non-locking position relative to the stop 62a is effective to retain the door 15 in opened position by lifting the plunger against the force of a spring 620 normally urging the plunger downwardly out of the path of the stop 62a.
The lowermost newspaper of a stack of newspapers 17 within the cabinet accordingly rests upon the upper surface of panel 71. The door 15 is also provided with a window 72 of such size as to fully expose a newspaper in upright position while such newspaper is supported on a rack 73 secured to the inner surface of door 15 in a position directly opposite the window 72. When the lowermost newspaper of the stack carried by the panel 71 has been disposed of, and the contents of the rack 73 have likewise been removed, a legend EMPTY applied to the surface of the rack exposed through the window 72 provides a visual signal that the cabinet is empty.
For the. purpose of servicing the vending apparatus thus equipped with a latching unit in accordance with this invention, the compartment door 19 is provided with a conventional key-operated lock 75 which is accessible via an opening in the door 15 directly opposite said lock;
Through suitable linkage between said lock and the control member, the control member may be operated to release the book 25 as an incident to operation of the key to open the lock which allows the door 15 to be opened for access to the compartment containing the coins without requiring a coin to be deposited in the chute.
