IMPROVEMENT IN FEED-CUTTING ATTACHMENT TO THRESHINGr-MACHINES.

The Schedule referred to in these Letters Patent and making part of the same` To all whom tana/y concern:

Be it known that 1 GEORGE W. Lnn, of Sandy, m the' county of Columbiana, and State of Ohio, have invented a new and improved Feed-Cutting Attachment for rlhreshing-Machines; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable others skilled in the art to therewith, to accomplish the work faster and in av better manner than can be done by cutting-npparatus now in use.

Figure 1 represent-s a sectional elevation of a threshing-apparatus provided with my attachment.

Figure 2 represents a plan view of thc saine.

parts. A represents theordiuai'y threslling-cylinder, and B, the concave shell thereof, provided with spikes.

C represents thefecding-tablc to beemployed when threshing.l

1) represents a concave attaclnnent, provided with a series ofsaws, E, arranged vertically in the face thereof, which, in connection with the spikes of the cylinder, are designed for cutting the corn-stalks or othersubstance into short lengths, previous to being ycarried down to be acted on both by the spikesof the cylin-` der and those of the shell l, whereby it is broken into tine'partieles. f

To form a hopper to facilitate the` feeding of the material to be cut, I provide the aprons F and G, the former hinged to the part D, and the latter hinged to the fixed portion H of the casing of the cylinder. v

'When the machine is to be used for cutting,r feed, these aprons are adj ust-ed to the positions represented in the drawing, and secured there by the hooks I K, and the plate L, which is pivoted to the end ofthe apron G, and rests at its lower end ina staple, IWI, shown in dotted lines.

\Vhen the machine is to bensed for threshing, these aprons are adjusted to the positions shown in dotted lines, closing the opening into the top of the apparatus,

where the material to be cut placed -transversely,

and the plate L folds down, closing an opening in one end of the casing/to permit the substance being out to project, as is sometimes necessary, when longer thanv the breadth of the machine.

Similar letters of reference indicate corresponding specified.

By this arrangement I am enabled to provide a cheap and simple feed-cutting attachment, which may be either permanently or'detacha-bly connected to the tln'eshing-maehine, and the breaking-devices of the latter utilized to facilitate. the preparation of the feed, h saws, together with the spikes of the cylinder, serving` to cut the straw or corn-stalks into short pieces, and the said cylinder-spikes in the casingr finish the operation by breaking the said pieces into tine particles.

I consider the arrangement of the saws E, in combination with the spiked cylinder, an important feature of my invention, as by it the substance is severed lnore easily, while amore important advantage thereof is the action ofthe saws upon the severed ends, which leaves the tibre in a soft and broken condition, which does not injure theanimals in eating, whereas when ont smoothly, especially corn-stalks, the substance of which is hard and compact, sharp points are formed, which are very injurious to the months ot' the animals, and often re quirc steaming before it is safe to feed them.' y,

I wish it, therefore, distinctly understood that I do not conline myself to combining my device to a threshing-machine, as itis evident that I may fix up a inachine with a spiked cylinder, and the saws E,`\\ 'ithont any apparatus for threshing, and which would answer all the purposes of the attachment above described.

Having lthus fully described my invention,

That I claim as new, and desire to secure by Letters Pat-cnt, is-

1. rIhe combination oi a series of lixed saws with a spiked cylinder or its equivalent, for eut-tingr feed, substantially as herein set forth.

2. The combination, with the toothed cylinder and" toothed shell of a threshing-machine, of the attach-v ment D, provided with saws,A and either permanently or detachably connected thereto, substantially as specified.

3. The aprons F G, combined with the attachment 1) and the casing- H, and arranged substantially as 4. 'Ihe plate L, combined with the apron G,the casing H, and attachment D, when arranged substantially as specified. l l

In testimony that I claim the foregoing, I have hereunto set my hand, this 22d day of October,` 1869.

' GEORG-E VST. LEE.
