 section. 



Vertical 



the other is rieidly attached to its axle, which revolves in bearings attached to the 

 frame B. To the frame B is attached the platform C, to the front of which are attached 

 a number of guards or fingers, D, which are curved upwaid, and are designed to enable 

 the machine to pass over obstructions, and to cause the grasshoppers to rise from the 

 ground and fall upon the platform C. 



The platform C is grooved or rabbeted, as shown in Fig. 73, and is made highest in 

 the center, and declines toward the front and rear, that the grasshoppers may be 

 crushed against the shoulders of said rabbets or grooves by the cross-bars E, attached 

 to the endless belts F. The cross-bars E are rounded off upon their forward corners, 

 so that they may pass over the grooves or rabbets of the platform C. The endless 

 belts F pass over pulleys G, attached to a shaft, H, the journals of which work in 



bearings in the forward parts of the side 

 boards cf the platform C, and over pulleys 

 I, attached to a shaft, J. The journals of 

 the shaft J revolve in bearings in the rear 

 parts of the side boards of the platform 

 C, and to one of said journals is attached 

 a gear-wheel, K, the teeth of which mesh 

 into the teeth of the gear-wheel L, at- 

 tached to the journal of the roller M. 

 To the journal of the roller M is also at- 

 tached a gear-wheel, N, the teeth of which 

 mesh into the teeth of tlje gear-wheel O, 

 attached to the revolving axle of the 

 wheel A. The teeth of the gear-wheel 

 N also mesh into the teeth of the gear- 

 wheel P, attached to the journal of the ^oller Q, placed parallel with the roller M. 

 The rollers M Q are placed at the rear edge of the platform C, so that any grasshop- 

 pers that may not be killed by the cross-bars F may be crushed by and between the 

 rollers M Q. 



The journals of the forward roller M revolve in stationary bearings attached to the 

 frame B, and the journals of the rear roller Q revolve in movable bearings, which are 



held forward by springs, 

 R, so that the said roller 

 Q may adjust itself ac- 

 cording to the number 

 of grasshoppers passing 

 through the machine. 



To the frame B are 

 attached scrapers S, to • 

 scrape off the crushed 

 grasshoppers from the 

 rollers M Q. To one of 

 the forward corners of 

 the frame B is hinged the 

 end of the draw-bar T, to 

 the forward end of which is hinged the, t'^ngue U. The draw-bar T is strengthened 

 against side draught by the brace V, the forward end of which is attached to the for- 

 ward part of the said draw-bar T^ and i*^s 

 rear end is attached to the frame B, near 

 its other forward corner. 



To the draw-bar T is attached a lever, 

 \y, which extends back into such a position 

 that it may be conveniently reached and 

 operated by the driver from his seat, to 

 raise and lower the forward edge of the 

 platform C. The lever W may be secured 

 in place, when adjusted, by catches at- 

 tached to the frame B, or to the side board 

 of the platform C. The draw-bar T is sup- 

 ported by a small caster-wheel, X, at- 

 tached to it. 



To the other corner of the frame B is 

 attached a guard-board or shield, Y, to pre- 

 vent the grasshoppers from escaping, and 

 to cause them to fall upon the platform C. 

 Z is the driver's sea*-, the standard of 

 Top which is attached to the frame B, and is 

 provided with rests for the driver's feet.
