- FIGURE 10 is a wiring diagram.
- FIGURE 11 is a modified wiring diagram.
- the numeral 1 indicates a casing having a bottom wall 2, side walls 3, a rear wall 4- and a front wall 5. Inwardly projecting prongs 7 on the wall 4 engage the side walls 3 to releasably secure said wall to the casing.
- the wall 5 is secured to a receptacle 9 which is slidably mounted in the casing and is adapted to be completely removed therefrom.
- the several casing parts are preferably of an electrically non-conducting material such as plastic or the like.
- a cover 10 which is supported on the side walls 3. Adjacent the front wall, the cover has a rectangular opening 11 which is bordered by a downwardly projecting flange 12.
- the casing 11 encloses a metal frame 15 which has limited rocking movement about trunnions 16 carried by the side walls 3.
- a transversely extending leaf spring 18 is secured to the base 19 of the frame and normally supports said frame in a horizontal position.
- the sides 2% of frame 15 are connected by a central partition 21 and are preferably reduced in height to the right of said partition as viewed in FIGURE 3.
- a cross bar 22 on the rear of the frame 15 supports a T-shaped arm 23 which extends forwardly to the vicinity of the opening 11.
- the arm 23 is fitted with a flexible scraper blade 26 which is secured along its upper edge only. Beneath the arm 23 a pair of bearings 27 slidably support a plunger 28 37, having a slot 38, extends from the left edge 39 of the.
- bracket 42 which journals a vertical spindle 43.
- the spindle is fitted at its upper end with a horizontally disposed crank 44 having a vertical pin 45 at its free end which extends through the slot 38.
- Supported on the bracket 42 is a small electric motor 47 having a drive shaft 4-3.
- the bracket also supports a suitable reduction gear train which is indicated by the numeral 50.
- This train includes a worm 51 on the shaft 48 and a gear 52 on the spindle 43, and through said train the motor 47 is adapted to rotate the crank 44 in a clockwise direction as viewed in 'FIG- URE 2.
- the motor 47 is powered by a pair of flashlight batteries 5 and said batteries are connected in series by means of a contact bar 55 which is carried by the rear wall 4- of the casing. Included in the motor circuit 56 is a timer 57 which is mounted on the partition 21 in opposition to the spindle 43.
- the timer is shown to consist of a cylinder 58 which is fitted with a piston 59 having a rod 60.
- the rod 60 projects through the head 61 of the cylinder and is provided near its outer end with an annular groove 62.
- a coil spring 63 is interposed between the piston 59 and the end 64 of the cylinder and adjacent said end the cylinders peripheral wall has a metered aperture 65.
- a reset cam 67 Aligned with the piston rod 69 is a reset cam 67 which is mounted on the spindle 43.
- the piston 59 is normally supported in the cylinder, against the pressure of the spring 63, by a resilient latch 7 0 which is secured to the partition 21.
- the latch seats in the piston rod groove 62 and has a leg 71 which extends downwardly through an opening 72 in the base 19 of the frame and into contact with the bottom wall 2, of the casing, see particularly FIGURE 9.
- a stud 74 Extending through the cylinder head 61 is a stud 74 which is electrically connected as at 75 to a contact 76.
- a second contact 77 extends rearwardly from the partition 21 and with the contact 76 forms a normally open switch 78.
- the spindle 43 is fitted with a cam disc 80 having a recess 8-1 on its peripheral edge and, as shown in FIG- URE 7, the hooked end 82 of the contact 77 normally is lodged in said recess.
- the mechanical ash tray is adapted to be automatically set in motion when a cigarette or the like is pressed against the plate 3 as most smokers do to extinguish a butt. This action results in the frame 15 being rocked about the trunnions 16 so as to compress the spring 18. Since the leg 71 of the timer latch rests upon the bottom Wall of the casing, the rocking movement of the frame raises said latch and releases the piston 59.
- the released piston is moved along the cylinder 58 by the spring 63 with its rate of motion being determined by the strength of the spring and the size of the metered aperture 65. After a predetermined interval the piston engages the stud 74 to complete the circuit 56 and energizes the motor 47. As the spindle is rotated by the motor, the crank 44 withdraws the plate from beneath the opening 11 and the blade 26, in contact with the top surface of the plates, wipes the debris therefrom so that it drops into the receptacle 9.
- the edge 39 engages the portion 29 of the plunger and retracts it to compress the spring 30 and to place said portion in the path of travel of the pin 45.
- the pin engages the portion, raising and releasing it from the edge so that the plunger shoots forward and strikes the wiper blade a sharp blow. This clears the blade 26 of ash and other clinging particles which might otherwise stick to the blade, and the plate is then free to return to its original position without picking up traces of ash.
- the completely extended piston rod is disposed in the dotted line position of FIGURE 8 and an abutment with the edge of the reset cam 67. As this cam is rotated by the spindle, the piston is forced into the cylinder and the latch 70 again engages the groove 62 and resets the timer for the next cycle of operation.
- the circuit 85 of the modification shown in FIGURE 11 includes, in addition to the motor 47, batteries 56 and switch 78, a push button two point make switch 86.
- This switch is mounted on the exterior of the casing and is adapted to be closed by the smoker after he has depos ited a butt and other articles on the plate 34.
- By momentarily closing the switch 86 circuit 85 is energized to start the motor 47 whereupon the cam disc 80 closes the switch 78 so that the motor continues to operate when the switch 86 is subsequently released.
- the contact 77 entering the recess 81 on the cam disc stops the motor as before.
- a self-cleaning ash tray comprising a casing having a top opening, a plate depressably supported in the casing beneath the top opening, said plate being slidably mounted for reciprocatory movement in a horizontal plane, a wiper blade engaging the top surface of the plate adjacent a side edge thereof, a motor in the casingand having a drive shaft, reciprocating means operatively connecting the drive shaft of the motor to the plate, means for starting the motor in response to downward pressure being applied to the plate and means for stopping the motor as the plate returns to its original position beneath the top opening.
- a self-cleaning ash tray comprising a casing having a top opening, a receptacle removably mounted in the casing below the top opening, a plate interposed between the top opening and the receptacle, said plate being mounted for limited movement towards the receptacle and for reciprocatory movement in a horizontal plane, a wiper blade engaging the top surface of the plate adjacent a side edge thereof, a motor in the casing and having a drive shaft, reciprocatory means operatively connecting the motor drive shaft to the plate whereby to impart a cleaning stroke and a return stroke to said plate, means responsive to initial downward pressure applied to the plate for starting the motor and means for stopping the motor at the completion of the return stroke of the plate.
