Toallzohom itmay concern:

Be it known that I, ALBERT H. HEAD, a citizen of the United States, residing at Hood River, in the county of Hood River and State of Oregon, have invented certain new and useful Improvements in Sizing-Machines, of which the following is a specification.

This invention relates to sizing machines,

-being adapted particularly to be used in sizing or grading fruits and vegetables.

The primary object of this invention is to provide a sizing apparatus which shall be of extremely simple and inexpensive con struction, which is capable of being operated with a relatively small amount of power, and which will distribute vegetables or fruits of various sizes to their proper places upon the grading table.

A still further object of the invention is to provide a device of the character mentioned which is of inexpensive construction, and yet which performs its functions perfectly and without likelihood of bruising or crushing the articles graded.

lVith these objects in view, together with others which will appear as the description proceeds the invention resides in the novel formation, combination, and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings, and

pointed out in the claim.

In the drawings 2* Figure 1 is a top plan view of a sizing apparatus constructed in accordance with the invention,

Fig. 2 is a side view of the improved apparatus, and

Fig. 3 is a sectional view taken upon line 3-3 of Fig. 1.

Referring now particularly to the drawings, 5 indicates a framework of any suitable size and construction, and which is adapted to inclose and support the two sizing rolls. The ends 6 of the frame have suitable openings arranged in spaced parallel relation, and within which the journals 7 of sorting or sizing rolls 8 engage. These sizing rolls are arranged in spaced parallel relation, and rotate in the same horizontal plane. I

The rolls 8 in the present instance are of worm or spiral formation, and the grooves in the said roll increase in depth from one end to the other thereof. It will be ob- WHIEE:

served that :the rolls are so arranged .within the supporting frame that the ridge portions of the spirals will correspond with each other, so that the grooved portions of the said rolls will form openings between them. By having the grooved portions of the spirals increasing in depth from one to the other end of the cylinder or spiral it is obvious that the openings will correspondingly increase in size.

Each of the spiral members is provided at one end with a gear 9 in mesh with the gear of the opposite roll, and it is obvious therefore that rotation of one of the rolls will be transmitted to the other roll. Any preferred means may be-employed for imparting the necessary movement to the rolls, one of the journals of one of the rolls being extended and provided with a belt pulley 10, over which a belt 11 is trained.

In operation, the frame and the grading spirals or rolls are arranged above the grading table, and the said rolls are set in motion through the belt 11. The articles to be graded or sized are delivered to the rolls at the end where the grooves therein are shallowest. The rotary movement of the rolls causes the articles to be carried toward the opposite end thereof, and as the articles progress, they will drop through the openings corresponding to their sizes. The articles thus deposited upon the grading table will be properly separated and may be removed to suitable boxes when desired.

From the foregoing it is obvious that I have provided a sizing apparatus which is of extremely simple construction and which will efiiciently perform its functions. It is preferred that the rolls be so constructed as not to present any sharp edges, so that danger of bruising or otherwise injuring the fruit will be obviated.

While the present is a disclosure of the preferred embodiment of the invention, it is to be understood that the invention is not limited thereto, as various changes in the minor details of construction, proportion, and arrangement of parts may be resorted to if spirit of the invention as defined by the appended claim.

I claim V In a device of the class described, a pair of spirals arranged in spaced parallel relation with their outer peripheries close todesired without departing from the gether and spaced apart an equal distance of the spirals, and means for rotating said 10 throughout the length of the said spirals, spirals.

the threads of said spirals having an even In testimony whereof I aflix my signature pitch, the grooves of said spirals being of dein presence of tWo Witnesses.

creasing depth throughout the length of the ALBERT H VVHITEHEAD spirals, providing oval shaped openings between the said spirals having their major Witnesses:

axes of equal length and the minor axes of F. E. NEWBY, increasing length from one end to the other A. J. DERBY.

Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.
