## Background
TECHNICAL FIELD
The present invention relates to fee collection, and more particularly to an unmanned fish proof fee collection device.
BACKGROUND ART
Campgrounds, picnic areas and parking areas in remote areas often use unmanned collection devices for fee collection. Generally, a user puts the fee into a provided envelope, writes identifying information on the envelope, such as a site number or a license plate number, and pushes the envelope through a fee slot in such fee collection devices. Prior known fee collection devices have several vulnerabilities and problems.
Thieves will attempt to fish envelopes back out of the fee collection device through the fee slot. Some prior known fee collection devices include a downwardly angled plate with a serrated lower edge to prevent such fishing. With fee collection devices with a single plate with a serrated lower edge, thieves are often able to push the line away from the serrated edge and successfully fish envelopes out. U.S. Pat. No. 134,321 to Slawson discloses a fare-box for use in street-cars, omnibuses, and other public conveyances with several plates with serrated lower edges.
Some prior known fee collection devices have small fee slots to inhibit fishing. Such small fee slots do not allow the use of coin packed envelopes. Other fee collection devices are locked with padlocks with shackles that are vulnerable to bolt cutters.
Some prior known fee collection devices have an interior that is only accessible through the top of the device. Accessing envelopes for collection and cleaning the interior is difficult in these devices. Other prior known fee collection devices have an access door lower on the device for envelope collection. These lower access doors can compromise the device strength and provide a point of vulnerability to thieves.
DISCLOSURE OF THE INVENTION

The second plate 52 is spaced below the first plate 48, extends laterally from one side plate 42 to the other side plate 42, and projects downwardly, forwardly from the back 44. A rectangular tab 55 projects from each side edge of the second plate 52 at the upper edge 53, and each side plate 42 has a plate aperture 56 that has the shape of a portion of a circle. The plate apertures 56 are sized and positioned to receive the tabs 55 and allow the second plate 52 to rotate about the upper edge 53 through a selected angle.
The chamber 15 includes a third plate 58, spaced below the second plate 52, and having an upper edge 59 and a spaced, serrated lower edge 60. The second plate 52 extends laterally from one side plate 42 to the other side plate 42, and projects downwardly, rearwardly from the front 43 with the lower edge 60 of the third plate 58, extending rearwardly of the lower edge 54 of the second plate 52. A rectangular tab 61 projects from each side edge of the third plate 58 at the upper edge 59, and each side plate 42 has a plate aperture 62 that has the shape of a portion of a circle. The plate apertures 62 are sized and positioned to receive the tabs 61 and allow the third plate 58 to rotate about the upper edge 59 through a selected angle.
The side plates 42 of the chamber 15 shown are connected together by a front plate 64, an upper back plate 65, a lower back plate 66 and a bottom plate 67. The front plate 64 is spaced below the upper edge 49 of the first plate 48 and extends downwardly to the upper edge 59 of the third plate 58 at the front 43 of the chamber 15. The upper back plate 65 is spaced inwardly from the back 44 of the chamber 15, extends from the upper end 45 downwardly to the upper edge 53 of the second plate 52, and angles slightly rearwardly. The lower back plate 66 extends downwardly, rearwardly from the lower edge 54 of the second plate 52 and supports the lower edge 54 of the second plate 52. The bottom plate 67 is positioned parallel to and below the third plate 58 and supports the third plate 58.
A cylindrical handle 69 connects between the side plates 42 of the chamber 15, behind the upper back plate 65, for lifting the chamber 15. Hooks 70 are attached to each side plate 42 at the front 43 and the back 44 of the chamber 15, near the lower end 46.
A spacer block 72 is mounted to the outside of each side plate 42 near the upper end 45 of the chamber. An elongated support arm 73 is attached to the outside of and extends downwardly from each spacer block 72. The support arms 73 are sized and shaped to fit into and slide in the retaining plates 38 of the tube 14. Preferably the support arms 73 are metal strap. The spacer blocks 72 rest on top edge 38 of the retaining plates 38 and are positioned such that the upper end 45 of the chamber 15 aligns with the top end 19 of the tube 14.
The support arms 73 extend downwardly a selected distance below the lower end 46 of the chamber 15 to a rounded bottom end 75. A stop pin 76 projects laterally outwardly from each support arm 73 near the bottom end 75. The stop pins 76 are sized to fit into the retaining plate notches 41. The support arms 73 allow the lower end 46 of the chamber 15 to be lifted above the top end 19 of the tube 14 while the stop pins 76 prevent complete removal of the chamber 15 from the fee collection device 11.
The support arms 73 each have an angled support notch 77 spaced above the stop pin 76 and extending upwardly, inwardly. The support notches 77 are sized to receive the top edges 39 of the retaining plates 38. The support notches 77 allow a user to rest the chamber 15 above the tube 14.
The top of the upper back plate 65 of the chamber 15 has a downwardly extending, rectangular staple notch 79. A lock staple 80 mounts on the upper back plate 65 and projects upwardly into the staple notch 79. A plunger aperture 81 extends through the lock staple 80.
The bonnet 16 rotatably mounts to top end 19 of the tube 14 to move between an open position and a closed position. The bonnet 16 has a top plate 84, a front plate 85, a back plate 86 and a pair of spaced side plates 87. The top plate 84 covers the top end 19 of the tube 14 when the bonnet 16 is in the closed position. The front plate 85, back plate 86 and side plates 87 project downwardly from the top plate 84, outside of the front wall 25, back wall 26 and side walls 27 of the tube 14 when the bonnet 16 is in the closed position. Hinge pins 88 project inwardly from each side plate 87 into the outer side plates 32 of the fee chute 29 to rotatably mount the bonnet 16 to top end 19 of the tube 14. The front plate 85 has an upwardly extending, rectangular fee notch 89 that aligns with the chute notch 35 to define a fee slot 90 for users to insert fees into the fee collection device 11.
The bonnet 16 includes a means for locking 92 the bonnet 16 in the closed position. The means for locking 92 shown includes a puck lock 93 and a channel 94 attached to bottom of the top plate 84. The channel 94 is sized and shaped to receive the puck lock 93 and attach the puck lock 93 to the top plate 84. The puck lock 93 has puck shaped body 95 with a slot 96 that extends through the body 95, and a plunger 97 that extends across the slot 96 when the puck lock 93 is locked.
The puck lock 93 is positioned under the top plate 84 such that when the bonnet 16 is closed, the lock staple 80 projects into the slot 96, and when the puck lock 93 is locked, the plunger 97 extends through the plunger aperture 81 of the lock staple 80. A rectangular key aperture 98 through the top plate 84 extends forwardly from the back plate 86 for accessing the puck lock 93 with a key.
The collection bag 17 has an open top end 100 and a spaced, closed bottom end 101. The top end 100 is sized to fit around the lower end 46 of the chamber 15 and is removably attached to the chamber 15 by the hooks 70. The collection bag 17 is preferably made of canvas or other sturdy fabric.
The serrated lower edges 50, 54 and 60 of the first, second and third plates 48, 52 and 54 of the chamber 15 prevent fishing fees out of the fee collection device 11. The rotatable mounting of the second and third plates 52 and 54 of the chamber 15 enhances the fishing prevention. The use of the puck lock 93 to lock the bonnet 16 eliminates any lock shackle that would be vulnerable to bolt cutters.
The removable chamber 15 and collection bag 17, in combination with the support arms 73, allow easy fee collection and tube cleaning. The removable chamber 15 and collection bag 17 also eliminate the need for a lower access door that could compromise the device strength and provide a point of vulnerability to thieves.
Although the present invention has been described with a certain degree of particularity, it is understood that the present disclosure has been made by way of example and that changes in details of structure may be made without departing from the spirit thereof.
