PLANER FEED ROLL Filed Sept. 7, 1948 \uven'roa M. Evme-r-r Dma Bemmm JDWKEMA ATTORNEYS Patented July 22, 1952 arm Q QRQLLQ 2 Claims.

1 This invention relates to a novel and very useful planer feed roll.

It is an object and purpose of the present invention to provide a novel sectional roll, used in wood planers, for feeding lumber to the planer knives, which will be positively driven, economical to construct and in which the sections of the roller are cushioned against shock and vibration and particularly one in which the roller sections and the cushioning means associated therewith are readily assembled upon the shaft which extends through the roller. 7

An understanding of the invention may be had from the following description taken in connection with the accompanying drawing, in which,

Fig. l is a longitudinal vertical section through the sectional feed roller, the shaft thereof being shown in elevation, and,

Figs. 2 and 3 are transverse vertical sections on the planes of lines 2-2 and 3-3, respectively, of Fig. 1.

Like reference characters refer to like parts in the different figures of the drawing.

The shaft I of the roller, for the major portion of its length and between its ends, is shown as enlarged to a larger diameter as at 2 and lengthwise of said enlarged roller section three spaced longitudinal radially disposed slots 3 are machined. The number of the slots shown in the disclosure is three, but the invention is not necessarily limited thereto. In each of said slots a plurality of metal ribs or vanes 4, each rectangular in cross section, are inserted and welded, preferably, in place, the outer edges of said vanes extending beyond the peripheral surface of the shaft and each extending out substantially the same distance. The vanes 4 around the shaft in groups of three, one for each of the slots 3, are spaced from each other lengthwise of the shaft, and are located in planes midway between the ends of the roller sections operatively associated therewith.

Each of the roller sections includes a cylindrical or tubular outer member 5, at the inner side of which a plurality of segments 6 are located and welded in. place. Said segments are spaced apart at adjacent ends a greater distance than the thickness of vanes 4, and at their inner sides are spaced from the outer peripheral surface of the shaft section 2 about which they are located. The segments 6 are also of the same length dimension as the like dimension of the vanes 4, and are located centrally between opposite ends of the tubular members and at equal distances from each end thereof. Said 2 roller sections are located over the shaft with the vanes 4 extending into the radial spaces between the adjacent ends of the segments 6.

In each end of each of the tubular roller members 5, a length of rubber rod I is inserted, being cut and shaped into a circular or ring form so as to be received one in each end of each of the tubular roller members 5 and one against each end of each of the segments 6 welded there.- in, the rings of rubber rod thus made extending from the outer surface of the shaft section 2 to the inner surfaces of the tubular roller sections 5. At the adjacent ends of the roller sections the rubber rings 1 are in contact engagement as shown in Fig. 1.

The sections of the roller made as described have a limited freedom of movement with respect to the shaft 2, due to the spacing of the shaft from the inner sidesof the segments 6 and between the sides of the vanes, 4, and the ends of such segments. The resilient rings I normally maintain the outer tubular sections 5 in alinement so that a generally cylindrical feed roller is provided, but with the several roller sections radially movable inward and outward with such movement resisted by the resilient rings 1. This provides a feed roller for planers which eliminates springs and reduces noise of operation but permits sections of the roller to yield in conforming to irregular surfaces of lumber, boards or the like against which it bears.

This roller will feed the material efiectively in both directions. In the event that an abnormally tapering piece is fed into the planer that will not go through the cutter, the machine may be stopped and reversed and the piece backed out. This is a great advantage over lowering the bed to remove the piece thereby destroying the accurate bed setting.

The structure is very practical and useful and is readily manufactured and assembled.

The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.

We claim:

1. A planer feed roll comprising, a plurality of tubular sections located end to end, a shaft extending through the tubular sections, a plurality of spaced vanes connected with the shaft and extending radially therefrom, each of said vanes being of less length than the tubular section with which associated and the vanes around the shaft being located within each of said sections centrally thereof, a plurality of segments shorter than said sections concentric with the shaft and spaced from each other secured at the inner sides of each of said tubular sections, having substantially the same length as said vanes with the vanes extending into the spaces between the segments, and a ring of resilient material in' each end of reach of said tubular sections located aroundthe shaft and bearing against the shaft at its inner side and against the inner sides of the tubular section at its outer side, said rings in each tubular section extending between the ends of said segments and the ends of said tubular sections, whereby adjacent rings in successive sections resiliently bear against each other. 5

4 2. A structure as defined in claim 1, said rings of resilient material being circular in cross section.
