Claims. (Cl. 23598) My invention relates to a counting device, and onto the blades 2. The objects to be counted are particularly to a device for counting objects such directed onto the rotor blades 2 by any suitable as pieces of fruit prepared for canning. means, as for example a chute or slide H.

For a four bladed rotor a ratio of my invention comprises a rotor I provided with of 10 to l is desirable. In that case, the first disk a plurality of blades 2 and mounted upon a shaft IT may be calibrated in units from 0 to 40 with 4,0, 3 journaled between a pair of housing plates 4 the disk I! arranged to move through one unit for 40 held in spaced relation by a plurality of spacing each quarter revolution of the rotor l.

The arm 6 is pro-- tween the plates 4 for directing objects from the 50 vided with a weighted portion 1 by which the arm rotor blades 2 onto a conveyor 28, or other suitable is normally held by gravity against a stop 8. means for delivering the objects to a desired point A lever 9 is connected to the detent arm 6 for of delivery. The gate 21 is preferably provided moving the arm 6 out of the path of the blades 2, with a weighted arm 29, normally resting upon a 555 said lever 9 extending into the path of objects fed stop 30, and permitting a limited swinging move- 5 ment of the gate as objects are carried therepast by the blades 2.

The counting device is particularly adapted for use in the canning of fruit such as halved pears or peaches. In this connection, the pieces of fruit are delivered onto the slide I, either manually or by a suitable conveying means. As each piece moves downwardly along the slide I I onto a blade 2, the detent arm 6 is displaced to momentarily free the rotor. As the rotor turns under the load imposed thereon by the fruit, the piece of fruit drops from under the lever 9, thereby permitting the arm 6 to drop back onto its stop 8 in time to en age the succeeding blade and prevent further rotation of the rotor until the detent is again tripped by another piece of fruit. In this manner, the rotor is advanced step by step to carry the blades successively into the fruit receiving position. The rotation of the rotor l operates through the pinion 23 to actuate the cotmter NS for indicating the number of pieces of fruit delivered past the rotor.

The counting device may be mounted at any convenient station for keeping accurate count of the pieces of fruit passing therethrough. For example a counting device may be provided for each of the operators, or groups of operators, who initially halve the fruit for keeping count of the number of pieces of fruit prepared; or a counter may be arranged to keep a count of the pieces as they pass from one step to another in the canning process. The device may of course be used in similar manner in other connections where objects may be delivered onto the rotor blades for actuating the counting mechanism.

In the preferred embodiment of the device illustrated in the drawing, a partition 3| is mounted centrally between the housing plates 4. The blades 2 are formed with slots 32 to permit the blades to move past the partition; and the lever 9 is provided with a slot 33 arranged to receive the partition 3! with portions of the lever disposed on opposite sides of the partition.

In this arrangement, objects may be fed onto the rotor l upon either side of the partition 3|. This permits the objects to be classified as to grade by the operator as the objects are delivered to the counting device. At the same time, an accurate count is made of the total number of objects fed past the rotor l, irrespective of the grades of the objects. The objects, so classifled and counted may be carried to separate points of delivery by the conveyor 28.

Figure 4 illustrates a modified form of the rotor wherein the partition 3| is carried by the rotor I itself. The partition 3| is located substantially midway between the sides of the blades 4 so that objects may be fed onto the blade portions on either side of the partition according to the grade of each object.

A device for counting objects comprising a rotor provided with a plurality of blades upon which the objects may be directed and bodily supported for counting, the rotor being actuated by the weight of the objects, a detent controlled by the objects delivered onto the blades for limiting movement of the rotor, the detent being moved by objects fed onto one blade of the rotor for releasing the rotor and being arranged to be moved into the path of a succeeding blade for insuring the return of the detent to its initial position after each operation, means dividing each blade into a plurality of areas upon which the objects may be selectively fed, and a yieldable guide adjacent the rotor and cooperating therewith for directing the objects along an arcuate path.
