FREDERICK ALBERT TUTTLE, OF NA-AU-SAY TOWNSHIP, KENDALL COUNTY, ILLINOIS.

CULTIVATOR-SHIELD FOR CORN-CULTIVATORS.

To all whom it may concern:

Be it known that I, FREDERICK A. TUTTLE, a citizen of the United States of America, residing in the township of Na-au-say, in the county of Kendall and State of Illinois, have invented a new and useful Improvement in Cultivator-Shields for Corn-Cultivators, in which the following is a specification.

This invention relates to improvements in shield or fender attachments for corn cultivators and its object is to rovide a simple and eflicient device of this 0 iaracter for preventing the cultivator from covering or otherwise injuring the corn.

A further object is to provide a shield having novel power operated means whereby it will automatically clear itself of stalks, stones, lumps of dirt, etc, accumulating therein or thereupon.

Another object is to provide a fender which can be run close to the corn without injury to the corn.

Another object is to provide a shield which can be conveniently adjusted to meet various conditions of the corn, soil, etc.

With these and other objects in View the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

a In said drawings: Figure l is a side elevation of the apparatus. Fig. 2 is a vertical longitudinal section through the fender or shield. Fig. 3 is a plan view.

Referring to the figures by characters of reference, 1 designates parallel plates in the form of parallelograms connected in any preferred manner, as by bolts 2 and having sprockets 3 journaled therebetween. These sprockets form supports and guides for an endless chain 4 one ply of which is parallel with and above the lower edges of the plates. This chain has elongated pointed spurs i extending therefrom and designed to project below the plates 1, 1 when in their lowermost positions.

Abolt 5 extends through the front ends of plates 1 and pivotally mounted upon it is Specification of Letters Patent.

Application filed April 18, 1907.

Patented April 18, 1909.

Serial No. 368,847.

a draw arm 6 designed to be locked at any desired angle to the plates by means of a binding nut 7 engaging the bolt. Arm 6 extends forward and is adjustably mounted in a slotted bracket 8 designed to be attached to the shovel beam of a cultivator, a set screw 9 or other means being utilized for securing the arm in adjusted position within the bracket.

One of the sprockets 3 is secured to a short shaft 3 extending beyond a plate 1 and provided. with a sprocket 10. An arm 11 is pivoted on this shaft and is connected by a pivot pin 12 with another arm 13. Sprockets 14 and 15 are mounted on the pin 12 and rotate together, the sprocket 14 having a chain 16 thereon which drives sprocket 10, while sprocket 15 receives motion through a chain 17 from a sprocket 18 on a drive shaft 19. This shaft 19 constitutes the pivot of arm 13 and is designed to be journaled on the cultivator frame. A bevel gear 20 is loosely mounted on this shaft and designed to be coupled thereto by a feathered clutch 21 actuated in any preferred manner, as by a lever 22. Gear 20 meshes with a gear 23 on a shaft 24 having a gear 25 thereon which receives motion from a gear 26 meshing with a gear 27 on one of the supporting wheels of the cultivator.

It is to be understood that any desired number of these fenders may be attached to a. cultivator and the mechanisms can be driven from either or both of the supporting wheels of the cultivator. The rotation of the wheel or wheels will cause motion to be transmitted. through the gears, chains and sprockets so that as the fender is drawn forward the chain 4 is actuated in the direction of the arrow, Fig. 1, and the spurs 4 thus 0 erate to keep clean the space between tie plate.

What is claimed is:

1. A fender comprising spaced plates arranged on edge, an endless chain mounted for movement therebetween and carried thereby, cleaning spurs carried by the chain, and mechanism for actuating the chain.

2. A fender comprising plates mounted on edge, an endless chain movably mounted be- 'ment therebetween and carried thereby,

tween and carried by the plates, cleaning spurs carried by the chain, driving mechancleaning means carried by said device, and ism, foldable means for transmitting motion mechanism .for actuating said device. from said mechanism to the chain, and a I FRED. ALBERT TUTTLE. draw arm adjustably connected to the fender. Witnesses:

3. A fender comprising spaced members, PHILIP E. HAINES,

an endless flexible device mounted for move- ALBERT P. BAKER.
