Abstract
A can and bottle crusher and separator with stationary and oscillating tooth jaw plates confronting each other and converging with each other in a downward direction and dropping crushed glass and metal containers into the discharge chute. A glass discharging port in the bottom of the discharge chute directs glass particles directly into a collecting barrel. A gate is provided to alternately close the chute or to close the glass discharge port. The chute has a separating wheel at its bottom end to initially stop and then propel aluminum cans over the top of it. The wheel has magnetic belts to carry steel containers around with the wheel until they are stripped off and dropped into an appropriate barrel.
Claims13
A crusher and separator for metal and glass containers, comprising
- a crushing means for mashing such containers into scrap by reducing metal cans into flattened condition and glass bottles into small particles,
- an inclined discharge chute below the crushing means receiving the scrap from the crushing means and having a bottom wall with a lower end and a revolving separating wheel at the lower end of the bottom wall, the wheel revolving on a horizontal axis below the bottom wall and transverse to the chute and the wheel having a portion of its periphery protruding upwardly of the lower end of the bottom wall to obstruct smooth sliding of the flattened cans down and off the chute and causing the flattened cans to hesitate, the wheel having a magnet on its periphery to adhere flattened steel cans thereto, the wheel propelling flattened aluminum cans from the chute, the bottom wall of the inclined chute having a glass discharging port therein directly below the crushing means and spaced along the chute above the lower end thereof, the wheel having upper and lower portions of its periphery, the chute being adjacent the upper portion of the periphery for delivering flattened cans thereto, there being open and unobstructed space adjacent the lower portion of the periphery of the wheel to permit all flattened cans to move downward adjacent the lower portion of the periphery of the wheel,
- a deflector beneath the lower end of the bottom wall and adjacent the periphery of the separating wheel to knock the steel cans off the revolving wheel and magnet, the steel cans dropping at a location spaced from the discharging of the aluminum cans,
- and a movable gate traversing the glass discharging port and allowing crushed cans to slide thereover to the separating wheel, the gate being movable to open the port and permit glass particles to fall through at a location spaced from the dropping of the steel cans.

A crusher and separator for cans variously made of aluminum and at least part steel, comprising
- crushing means for mashing such containers into scrap by reducing the metal cans into flattened condition,
- an inclined discharge chute receiving scrap from the crushing means and having a bottom wall with a lower end and a revolving separating wheel at the lower end of the bottom wall, the wheel revolving on a horizontal axis below the bottom wall and transverse to the chute and the wheel having a portion of its periphery protruding upwardly of the lower end to obstruct smooth sliding of the flattened cans down the chute and causing the flattened cans to hesitate, the wheel having a magnet on its periphery to adhere flattened steel cans thereto, the wheel propelling the flattened aluminum cans directly from the chute, the wheel having upper and lower portions of its periphery, the chute being adjacent the upper portion of the periphery of the wheel for delivering flattened cans thereto, there being open and unobstructed space adjacent the lower portion of the periphery of the wheel to permit all flattened cans to move downward adjacent the second side of the wheel,
- and a deflector beneath the lower end of the bottom wall and adjacent the periphery of the separating wheel to knock the flattened cans off the revolving wheel and magnet, the flattened steel cans dropping at a location spaced from the discharging of the flattened aluminum cans.
A crusher for metal and glass containers, comprising
- frame means including a pair of upright rigid side panels confronting each other in spaced relation and defining a crushing chamber therebetween, the crushing chamber having open top and bottom ends,
- a stationary jaw plate and oscillating jaw plate both being upright and extending between the side panels and having working faces in confronting relation to each other to enclose the crushing chamber, the stationary jaw plate being affixed to the side panels and the oscillating jaw plate being movable between the side panels and being inclined in downwardly converging relation to the stationary jaw plate, each of the jaw plates having a back side opposite the working face and having a multiplicity of unbroken rib-like teeth extending horizontally and continuously across the working face thereof,
- a first driven rotary eccentric extending horizontally across and suspending the upper portion of the upright oscillating jaw plate for rotatably oscillating the upper portion of the jaw plate upwardly and downwardly and toward and away from the stationary jaw plate,
- a second driven rotary eccentric slidably bearing against the lower portion of the oscillating jaw plate at the back side thereof and to produce oscillation of the lower portion of the plate toward and away from the stationary jaw plate while also accommodating the upward and downward oscillation produced by the first eccentric, whereby to reduce containers to scrap as they are fed into the top of the crushing chamber by mashing metal cans into flattened condition as the cans are progressively pulled downwardly and breaking the glass into small particles,
- and means beneath the crushing chamber to collect and sort the scrap by the nature of the material in the scrap.

A crusher for metal and glass containers, comprising
- a stationary jaw plate and an oscillating jaw plate both being substantially upright and having working faces in confronting relation to each other to define a crushing chamber therebetween, the working faces being continuous and unbroken betwen the sides thereof, the oscillating jaw plate being inclined in downwardly converging relation to the upright stationary jaw plate, each of the jaw plates having a multiplicity of rib-like teeth extending horizontally and continuously across the working face thereof,
- means cooperating with said jaw plates enclosing the sides of the crushing chamber between the plates, a first cam operated driving means engaging and suspending the upper portion of the upright oscillating jaw plate and rotatably oscillating the upper portion of the plate upwardly and downwardly and toward and away from the stationary jaw plate,
- and a second drive means slidably bearing against the lower portion of the oscillating jaw plate at the back side thereof and opposite the working face and producing oscillation of the lower portion of the plate toward and away from the stationary jaw plate while also accommodating the upward and downward oscillation produced by said first cam operated driving means, whereby to reduce containers to scrap as they are fed into the top of the crushing chamber by mashing metal cans into flattened condition as the cans are progressively pulled downwardly and breaking glass bottles into small particles,
- and means beneath the crushing chamber to collect and sort the scrap.
