SNAPPER ROLLER PAD Application filed January 7, mi. Serial No. 507,265;

This invention broadly, has reference to corn picking machines, and the primary object of this invention is to provide a pad capable of use on the snapper rollers of the machine, and which pad will be found especially useful in dry weather.

A still further important object of this invention is to provide a pad for use with the snapper rollers whereby the passage of dry corn between the rollers will be accomplished with as much facility as is accomplished with the passage of damp corn stalks.

A still further object of the invention is to provide a pad for the purpose above men- 1 tioned, as will also aid in maintaining the rollers free from clogging, the pad having a tendency to work the stalks between the rollers at a much greater speed than heretofore has been accomplished, and which will further increase the efficiency of the machine in that the use of such pads will reduce to a minimum the number of corn stalks and leaves passing from the snapper rollers to the husking rollers.

A still further object of the invention is to provide a pad of the above mentioned character which may be applied with ease and facility to the snapper roller and which will, when applied, in no wise cause interference of one of the snapper rollers with the other. 7

Other objects and advantages of the invention will become apparent during a study of the following description, taken in connection with the accompanying drawings wherein:

Figure 1 is a plan view of the pad.

Figure 2 is an edge elevational view thereof and illustrating an application of the pad to a snapper roller.

With reference more in detail to the drawings, it will be seen that the pad comprises.

ably treated and suitably applied to the upper face of the uppermost layer or ply of canvas 5. i o

The rubber ply 6 at its rear or trailing transverse edge is flanged or bent downwardly as at 7 to contact the corresponding edges of the canvas plies 5. At the forward or leading edge of the pad, the corresponding edges of the canvas ply 5 are beveled and at said edge, the rubber ply 6 is turned down or flanged to contact and cover the corresponding edges of the plies 5 as at 8. Thus it may be stated, that at its meeting edge the pad' is beveled and by so forming the edge of the pad the possibility'of the corn stalk becoming caught is eliminated thus insuring' a steady passage ofthe stalk between the rollers;

From a study of Figure 2, it will be also noted, that the surface or top ply 6 is relatively thick adjacent the trailing edge of the pad, and gradually tapers or is reduced in thickness as at 6 as the ply 6 approaches the leading edge of the pad.

Adjacent its leading edge, the pad has the plies thereof suitably apertured to provide a bolt accommodating opening 9 and through which is passed the attaching bolt 10 that engages the snapper roller shown in dotted lines in Figure 2 and designated generally by the reference character R. 1 Thus the pad can be applied to the roller with a single bolt.

The pad is curved longitudinally to conformably engage the periphery of the roller, and it will be apparent that as the roller rotates, the rubber surface or plies 6 of the pad will provide a friction surface affording purchase for the dry corn stalks thus insuring a passage of the stalks between the rollers. Such passage of the dry stalks with a pad of this character applied to the snapper rollers will insure a continued passage of the stalks between the rollers preventing clogging as is often the case when picking corn during dry and torrid weather. As is well known during wet and damp weather, the possibility of the wet and damp stalks clogging between the snapper rollers is very limited. However in warm and dry weather the dry stalks are very apt to clog the roll ers, since the rollers are unable to attain sufficient frictional grip on the stalks for forcing the latter between the rollers.

The exact edge configuration or shape of the pad is immaterial, however preferably the pad is shaped as suggested in Figure 1, the plies 5 and 6 being cut from a substantially rectangular blank and then vtapered longitudinally toward 0ne: enditl1ere0f or toward the leading edge thereof as suggested in Figure 1.

Even though I have herein shown and desoribed'the preferred embodiment of the invention, it is to be understood that the same is susceptible of changes, modifications and improvements coming within the scope of the appended claim.

Having thus described my invention,-What I claimas new is:

i A pad for snappper rolls comprising a plurality of superposed layers of canvas each provided with a rectangular body portion and a tapered end portion, a facing sheet of rubber of like contour, said sheet being relatively thick adjacent one end thereof and progressively decreasing in thickness'toward the opposite end thereof, said sheet having opposite end portions thereof contacting-the corresponding ends of the layers, one ofsaid ends being provided with a thick flange por tion, and the opposite end being beveled, and

albolt receiving opening extending through.

thetapered end portion of the pad,

In testimony whereof I afii'x my signature.
