Abstract: An agricultural baler having a baling chamber and apparatus for loading successive charges of crop material into the chamber. The cross section of the baling chamber is automatically adjusted to the load experienced by the plunger during compression of these charges and thereby controlling the density of the bales formed therein. The density control system further comprises elements associated with the actuator of the baling chamber for precluding adjustment of the cross section when no new charge of crop material has been introduced into the baling chamber. These elements comprise a sensor sensing the passage of such charge along a wall portion of the baling chamber and a by-pass valve which controls the pressure of hydraulic oil provided to the actuator. Thus the cross section of the baling chamber is prevented from being reduced further when the baler is turned on headlands.

Abstract: During the pressing of bales in a baler, a portion of a press channel in front of a retracted press ram is in each case completely filled with material to be compacted. During compacting, the pressure forces exerted on the press ram have a resultant which intersects the side of the press ram directed in pressing direction below the center thereof or below the center of the press channel section at the location of that side of the press ram. The press ram shows less tendency to tilt, as a consequence of which the press ram guide is less loaded and less friction occurs between the press ram and the press channel. As a result, the bale is compressed more properly and the press ram guide wears less.

Abstract: An automatic can smasher having a frame assembly with a pair of parallel channel members in a spaced relationship for receiving a can to be smashed. A motor is attached to the underside of the frame assembly. The motor drives a plunger arm assembly having a reciprocating plunger that compresses and smashes the can. A switch mounted on a switch mounting plate is operated when a can is placed within the frame assembly. The switch activates the motor and the reciprocating plunger. A hole through the frame assembly in front of the switch mounting plate allows the smashed can to fall through the frame assembly. A can receptacle can be placed over the frame assembly for placement of a plurality of cans and for feeding the cans one at a time into the frame assembly. When the plunger is retracted, one smashed can drops through the hole in the frame assembly, the switch is released and opened and the next can is allowed to fall into place for being smashed.

Abstract: A paperboard carton piercing-crushing and recycle system and apparatus which includes a safety operated door which controls motor operated carton piercing and crushing rolls in order to crush paperboard cartons for disposal. The safety operated door is provided with a magnetic switch which controls two different timed electrical circuits. One circuit controls an electronic safety latch mechanism which prevents the carton disposal door from opening during operation of motor driven carton crushing rolls and one timed circuit operates the motor during the time that the electronic safety latch mechanism prevents the door from operating. When the motor circuit stops, the timer to the electronic safety latch mechanism releases the safety latch so that the door can be opened. Thus, the system is safe and will not operate if the carton disposal door is open.

Abstract: A can compactor includes an electric motor connected to drive a chain which, in turn, drives a pair of crushing belts arranged in opposing fashion to form a V. One of the belts is driven clockwise while the other belt is driven counterclockwise. Cans to be crushed are placed through a guide in an open area at the top of the two belts, where they break a light beam, triggering a photo-sensitive switch, which starts the motor. A normally closed limit switch is placed in close proximity to the chain drive, and a special link on the chain is positioned to engage the limit switch to open the normally closed switch, and thus stop the motor after a single revolution of the chain. This is sufficient time for the crusher belts to thoroughly flatten the can. Can gripping lugs on at least one of the belts assure that the cans are positively fed through the mechanism and out the bottom of the V.

Abstract: Apparatus for collecting and storing empty aluminum containers for recycling. The containers are inserted into a chute having a regulating feed mechanism. The cans fall out of this one-by-one into a crushing zone between a reciprocating ram and a stationary platen, and interrupt a sensor beam which initiates the crushing cycle of the ram. After crushing, the cans drop into a container past the outer end of a can stop. The stop is counterbalanced so that empty cans will be retained in the crushing zone for flattening, while partially full containers displace this and fall through. The drive mechanism for the ram is provided by a compound eccentric cam having thrust and retraction faces, and first and second roller followers for engaging these. Preferably, the assembly is mounted in a cabinet for inclusion in a stand of vending machines.

Abstract: A calendar for the production of packing sheets has a heated cylinder of large diameter on which a packing sheet is progressively built-up of layers of rubber-fiber mixture during many revolutions and the cylinder and an unheated counter pressure cylinder of smaller diameter mounted in slidable bearings for rotation and for movement toward and away from the heated cylinder. As the packing sheet is progressively built-up on the heated cylinder, its thickness is continuously measured by feeler rollers pressed lightly against the surface of the packing sheet and associated inductive sensors. In a comparison circuit, the values of thickness-indicating signals received from the sensors are compared with the sum of an initial zero value recorded before rubber-fiber mixture is applied to the circumference of the heated cylinder, and a predetermined desired value. When the value of the thickness indicating signal equals the sum of the zero value and the desired value, the calender is stopped.

Abstract: A potentiometer is driven by one of the serpentine arm assemblies used to maintain apron tension during formation of a round bale so that the output of the potentiometer continuously provides an indication of the size of a bale being formed in the baler. A microprocessor based control circuit senses the output of the potentiometer, converts it to a digital value, and compares the digital value with a value representing a desired bale size. When the two values are equal, the microprocessor computes the number of revolutions of a net feed roll that is required to wrap the bale a preselected number of times, energizes the net feed roll mechanism to feed net into the bale forming chamber, and counts the revolutions of the net feed roll. When the required amount of net has been dispensed, the microprocessor stops the net feed roll and activates a mechanism to cut the net. The size of a "full bale" is selected by actuating keys on a control panel.
