4 Claims.

This invention relates to canning machinery, and is more particularly concerned with a measuring valve device for use in connection with the canning of spaghetti or like material.

In canning machinery it is conventional to provide a source of the material to bercanned and a conduit leading from that source to a discharge nozzle which is fitted in 01' over the container to be filled. In the conduit connecting the source with th discharge nozzle it is customary to provide a measuring device or valve which is intermittently operated to dispense to the nozzle successive measured quantities of the material to be canned, each dispensing operation involving enough of said material to fill an individual can, jar or the like. Thus, the empty cans are successively placed in registry with the nozzle and are successively accurately filled as the measuring valve completes an operating cycle.

Of course, measuring valves of the general type mentioned above are at present well known and they conform to a wide variety of shapes adapted for various conditions of operation. It has been found, however, that in the canning of spaghetti or like material, peculiar problems are presented which render conventional canning machinery unsatisfactory. This difficulty arises largely because of the nature of spaghetti itself. Cooked spaghetti, when fed in bulk to a measuring valve, forms a continuous more or less air-locked column of such a nature that it is impossible to vent the measuring valve through the material, as is often done in the case of granular substances. Neither can an ordinary air vent be used because of the fact that spaghetti is made up of elongated components which, in cooked condition, will quickly clog an air vent of conventional form.

Furthermore, because of the fact that cooked spaghetti packs together to form a continuous body, there is a tendency to jam the valve as it moves from filling to dispensing position, thereby resulting in defective operation either from the point of View of timing or the amount of material dispensed.

It is, therefore, an object of this invention; to provide a measuring valve device particularly adapted for use in machines for canning spaghetti or the like, which valve is adequately vented during both the filling and discharge operations, and which is designed to sever the column of material upon movement away from the filling position in such a manner as to assure the filling of the chamber of the measuring valve and the rapid and clean severance of the remainder of the material from the measured amount.

Figure 2 is a front view of the measuring valve device partially in vertical section better to illustrate the structure of the rotating element;

Figure 3 is a view in section taken on line 3-3 V of Figure 2; and

Figure 4 is a top plan view of the rotary element of the valve removed from the assembly for convenience in illustration.

Referring now to the drawings in greater detail, it will be seen that the valve device is made up of a frusto-conical hopper I0, a measuring valve assembly I l and a discharge nozzle or fitting l2. Valve assembly I I is provided with a support I3 which is mounted on a base l4, resting in turn on a bench or platform l5 conveniently disposed within the cannery. Frusto-conical hopper l0 may be conveniently made of sheet metal with its small open end welded or otherwise attached to a rectangular plate l6 provided with a round centrally located opening equal in size to and registering with the discharge opening of the hopper. bolts [1 to an exteriorly flattened upper portion of an interiorly cylindrical valve housing 18, said housing having an aperture at |9 of an interiorly cylindrical valve housing in its upper wall registering with that in plate l6 and serving with it to establish communication between the hopper Ill and the interior of the valve housing l8.

Valve housing I8 consists of a hollow casting open at one end and there provided with a cover plate 20 attached by bolts 21, see Figure l. The bottom of valve housing [8 is provided with an integral flattened lower portion 22 in all respects similar to the corresponding upper portion to which plate [6 is bolted. Portion 22 is provided with a round central opening at 23 leading to the hollow interior of housing l8. The openings at l9 and 23 are disposed on a vertical axis apart. Nozzle I2 is attached by bolts 24 to the flattened lower portion 22 of valve housing It},

Upon reference to Figure 2 it will be seen that the material of which valve element 28 is made is thick but is beveledadjacent aperture 35, so that the actual defining edge of that aperture. is thin and sharp, resulting in the cutting action previously described.

In view of the fact that cooked spaghetti forms a continuous and compact body, it is insufficiently foraminous to permit the ready escape there- .through of the air which is displaced from valve element .28.during filling of its hollow interior. This being the case, filling would be considerably retarded were it not for the novel and convenient air. vent provided in accordance with thisinvention.
