Abstract
Abstract A plastic tine comprising a solid molded body adapted for mounting on a harvester crop pickup reel bat and having a finger portion of predetermined length extending from the tip of the bat at least half the length of the finger portion being of constant thickness in the front to rear flexure direction and of greater width than thickness for more than half the finger length, the finger width decreasing progressively from the edge of the bat to the tip of the finger, whereby the upper portion of the finger will flex in the fore-and-aft direction but not sideways except under extreme load, and will be resistant to breakage, distortion or taking a set.

Claim 1
Independent Claim
98 words
A crop pickup tine adapted for mounting on a harvester reel bat and having a bat attachment portion at its upper end and a pickup finger portion of predetermined length extending from the bat attachment portion, the finger portion of the tine having a constant thickness in the front-to-rear direction from adjacent its upper end to more than half the finger length and then decreasing progressively to the finger tip, and the finger width of the tine decreasing progressively from substantially twice its thickness at the said upper end to less than its thickness at the finger tip.
Claim 2
Dependent Claim
98 words
A crop pickup tine adapted for mounting on a harvester reel bat and having a bat attachment portion at its upper end and a pickup finger portion of predetermined length extending from the bat attachment portion, the finger portion of the tine having a constant thickness in the front-to-rear direction from adjacent its upper end to more than half the finger length and then decreasing progressively to the finger tip, and the finger width of the tine decreasing progressively from substantially twice its thickness at the said upper end to less than its thickness at the finger tip.
Claim 3
Dependent Claim
155 words
A crop pickup tine adapted for mounting on a harvester reel bat and having a length of 11.92 inches and a bat attachment portion extending 4.12 inches from its top end, and a pickup finger portion extending 7.8 inches from the said attachment portion, said finger portion having a thickness of 0.42 inch in the front-to-rear direction at its upper end and from 0.20 inch below that level a constant thickness of 0.38 inch for the next 3.6 inches of finger length, the finger thickness then decreasing progressively to 0.25 inch at the finger tip, and the finger width of the tine being 0.73 inch at its upper end and 0.70 inch at the next 0.20 inch below, the finger width then decreasing progressively to 0.38 inch at 3.8 inches below the said upper end, and the finger width and thickness then decreasing progressively to 0.19 inch and 0.25 inch, respectively, at the finger tip.
