WILLIAM A. ALLEN, OF COLEAX, TEXAS.

STALK-KNOCKER.

SPECIFICATION forming part of Letters Patent No. 372,735, dated November 8, 1887.

(No model.)

To all whom it may concern:

Be it known that 1, WILLIAM A. ALLEN, a citizen of the United States, residing at Colfax, in the county of Van Zandt, State of Texas, have invented certain new and useful Improvements in Stalk-Knockers, ofwhich the followingis a specification, reference being had therein to the accompanying drawings.

This invention has relation to stalk-knockers, and among the objects in view is to provide a stalk-knocking mechanism that is simple of construction, effective in operation, cheap,and which is adapted to be applied to the running gear of an ordinary farmwagon.

Other objects and advantages will be herein after described, and the novel features of the invention will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a side elevation of the running-gear of an ordinary farm-wagon with the body removed and provided with a stalk-knocking mechanism c011- structedin accordance with myinvention. Fig. 2 is a rear elevation of the same; and Fig. 3 is a modification in perspective, hereinafter referred to.

Like letters of reference indicate like parts in all the figures.

A A representthe front and rear wheels, respectively,ofa wagon, A the axle, A the reach, and A the bolsters,all ofthe usual construction.

13 represents an oblong framework, consisting of side and end rails, BB,wliichai'ci1iortised and bolted at each corner, as at B. This frame-work B is mounted upon the bolsters A" of the wagon, the body of the same having been previously removed,and may be retained in position on said bolsters by any suitable devices, such as pins, bolts, fee. The rear end of the frame-work at each side provided with longitudinal slots 13, having opposite pin-holes or perforations, B and adjnstablein the slots,and retained in position by means of pins B,passed through said holes, are depending hangers G, having at their lowerends bearings G,(in this instance open at one sidefland provided at their upper ends with a series of adjusting-holes or apertures, 0 adapted to receive the pin B, and thus be raised or lowered to any de sired height from the ground.

An inclined braccrod, D,.perforatcd as at D, is pivotally connected to the lower portion of each of the hangers O, as at D said brace being adjustable within the frame-work by means of a pin, D. By this arrangement of the brace the hangers may be swung away from or nearer to therear wheels, A,the object and purpose of which will be apparent.

The wheels A may be provided with a grooved or plain pulley, E, secured thereto in any suitable manner; but in this instance,and in order to provide an ordinary wagon-wheel with a drive-pulley, I prefer to form the pulley-wheel in sections E in the form of an arc of a circle. These sections are preferably castiron, and are formed with the oppositely-disposed lugs or ears'E adapted to embrace two adjacent spokes of the whoel,and when thus in position to form a continuous pulley or drivewheel. The sections shown in Fig. 1 are introduced with their lugs between two adjacent spokes near the rim of the wheel, and are then, by pressure or taps upon theirtops, driven down and seated firmly between the spokes, wedging in between the same. Several of these sections being placed in position, their ends may be secured by metallic straps or clips E".

Journaled in the open bearings G of the hangers O is the knocker-shaft F, (in this instance formed with the bearings orjournals F,) having radiating knockers F at each end, and a similar intermediate knocker. Small pulleys F are formed at each side of the shaft, and from these and over the drive pulleys or wheels E extend a rope belt, or it may be a belt of any desired character, G. By this arrangement it is apparent that when the wagon is in motion,

motion will be given from thepulloy E through the belt G to the pulley F and its shaft, rotating the knockers and thus clearing a field of stubble and stalks.

In Fig. 3 of the drawings I have illustrated a form of pulley-section whereby the same is adapted to fit any size wheel. In this instance the lugs for embracing the spokes are disposcd toward each other, and the section is introduced near the hub and driven upwardly to ward the rim of the wheel. The sections are preferably made somewhat shorter than in the construction previously described, so that gene ally there is a space between the same. The sections in this instance are secured to each other as in the other form-namely, by the metallic straps or clips In the modification the straps are made longer, and are provided with a series of perforations in order that the sections may be as far apart as the size of the wheel will require.

By the adjustable brace-rod D the hangers may be adjusted so as to keep the belt taut upon the pulleys.

Having described my invention and its operation, what I claim is- 1. The combination,with the running-gear of a wagon, of a framework mounted thereon and provided with vertically-adjustable hangers at its rear end carrying stalk-knockers and their shaft, a diagonal adjust-able brace connecting the hanger and the frame-work, and a drivingpulley formed in sections, having spoke-embracing lugs, and connected to the knockershaft by means of a belt, substantially as specified.

2. The frame B, slotted as at B, and having the hangers 0, adjustable in said slots, and provided with bearings C, having the shaft F, carrying knockers F in combination with the pulley'E, formed in sections E, connected as at E and having lugs E for embracing the spokes, said pulley and shaft being connected I by the rope or belt G,substantially as specified.
