Abstract

Abstract A shield device is provided on the tongue structure of a hay baler particularly of the type designed to form the bales in rolls. The shield is mounted between the operative baler machinery and the operator of a tractor pulling the same to prevent the swirling hay and dust from reaching and enveloping the operator and is of transparent material so that the operator can view the baler for observation relative to the several working components that may need attention from time to time.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 214 words
The combination of a hay baling unit consisting of a mobile hay baling machine of a type forming cut hay into tied rolls, a tractor with an operator''s station and hitched to said baling machine for towing the same and a shielding means operatively secured to said unit intermediate the baling machine and the operator''s station to prevent such station from being enveloped by swirling hay and dust generated by the normal operation of the baling machine, said shielding means comprising: a closed frame of angle material defining a pair of sides at right angles to each other, a third side secured to said angle material in spaced relationship to one of the sides thereof to form a track whereby said angle material defines generally an F shape, a deflector plate contoured to the shape of said frame and secured thereto by a frictional slip-fit engagement of the plate edge portion into said track, said frame having a top end and a bottom end, said baling unit including a tongue structure intermediate said baling machine and said operator''s station, and means securing said frame to said tongue structure in a generally upstanding position so that said bottom end is disposed tranversely of a direction of forward travel on said tongue structure and supported thereon.

Claim 3
Dependent Claim 32 words
The combination of claim 1 wherein said deflector plate is of transparent material to afford a means of visual observation from the operator''s station of the baling machine during the operation thereof.
