Description:

This invention appertains to new and useful improvements in vegetable graders and more particularly to a novel belt for grading machines. The principal object of the present invention is to provide a belt or screen construction of a multiplicity of hingedly connected links reinforced in such a manner as to promote durability and less likelihood of the ready developments of defects.

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawingsFigure 1 represents a fragmentary longitudinal sectional view through the belt.

Figure 2 is a fragmentary top plan view of the belt.

Figure 3 is a perspective view showing the inner side of one of the links.

Figure 4 is a sectional view taken substantially on line 4-4 of Figure 2.

Figure 5 is a sectional view on line 5-5 of Figure 2.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes the usual belt-carrying wheel on the shaft 6 and over which the belt generally referred to by numeral 7 is trained. This belt is made up of a multiplicity of links and one of which is clearly shown in Figure 3. Each link consists of a rectangular shaped plate 8 having its end rolled to form barrels 9-10 through which pins II are disposed for inter-connecting the links in the manner shown in Figure 2. 35 Certain of the pins II are bridged by the arcuate-shaped bridge members 12.

The longitudinal edge portions of the plate 8 between the barrels 9-10 are pressed inwardly to form flange members 13-14. These flanges extend from arcuate origin points on the head portion of the plate 8 and serve to reinforce the link against transverse bending. Obviously the barrels 9-10 serve to prevent longitudinal bending while the flanges 13-14 serve to prevent transverse bending. Furthermore, by having the flanges 13-14 originating from arcuate points on the longitudinal edge portions of the plate 8 a better grading opening is afforded.

The barrels 9--0 on their corresponding pins I I are separated from like barrels on the same pin by barrels of the links of adjacent rows.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter. Having thus described the invention what is claimed as new is: A belt of the class described comprising a plurality of pivotally connected links, each link being formed from a substantially rectangular metallic plate of uniform width throughout and including rolled end portions providing transverse barrels for the reception of connecting pins, the length of the barrels corresponding to the width of the plate, the longitudinal marginal portions of the plate between the barrels being bent at substantially right angles on inwardly and oppositely curved lines and providing arcuate flanges.
