PROTECTOR FOR KNOTTERS FOR BINDERS.

SPECIFICATION forming part of Letters Patent NO. 732,464, dated June 30, 1903. Application filed December 27, 1902. Serial No. 136,874. (No model.)

To @ZZ whom it may concern:

Be it known that I, FRANKLIN B. STOUT, a citizen of the United States, residing at Baltic, in the county of Minnehaha and State of South Dakota, have invented new and useful Improvements in Grain-Binders, of which the following is a specification.

This invention relates to grain-binders.

The object of the invention is in a ready, simple, thoroughly feasible, and practical manner to effect the stripping or removal from the needle of any attached material, such as straw or the like, which would tend to interfere with its proper operation and frequently causes the knotter to fail to tie the bundle; furthermore, to provide an attachment to grain-binders for performing the functions stated which shall be simple in construction, thoroughly efficient and durable in use, and which in case of damage or breakage may be readily repaired without the necessity of the employment of skilled labor for the purpose.

With these and other objects in View, as will appear as the nature of the invention lis better understood, the same consists -in the novel construction and combination of parts of a needle stripping attachment for grainbinders, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of the specification, and in whichl like numerals of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage Without departing from the spirit thereof, and iny the drawings- Figure 1 is a view in side elevation, partly in section, exhibiting so much of a grain,-

binder as is requisiteto render clear an understanding of the device of the present invention. Fig. 2 is a perspective detail view of the stripping attachment.

Referring to the drawings, 1 designates the decking of an ordinary grain-binder; 2, the overhead breast-plate; 3, `the binder-arm shaft; 4, the binder-arm; 5, the needle, and 6 the knotting mechanism. As these 'parts maybe of the usual or any preferred construction, detailed description thereof is deemed unnecessary.

The attachment which constitutes the gist of the present invention and which is shown indetail in Fig.`2 comprises a shank 7 of approximately an inverted- L shape in elevation, the upper or horizontal member of which is provided with an opening 8 to receive a bolt or rod 9, that is attached in any suitable manner to the machine, the said member 10 bearing upon a transverse rod 1l, rigidly connected with portions of the machine. (Not necessary to be shown.) By thus connecting the shank with the machine its detachment may readily be effected by loosening the nut 12, as shown in Fig. 1.

The stripping mechanism comprises two approximately parallel stripping-fingers 13 of the same length and a superposed strippingfinger 14 of less length than the two firstnamed fingers. The fingers 13 are by preference constructed of a single piece of resilient metal, preferably of steel, the metal being bent around the lower member 15 of the shank and held associated therewith by rivets or other equivalent form of fastening device. By passing the ngers around the shank in the manner described their rear portions are separated and thence converge to a point and meet in advance of the upper finger 14, and by this arrangement the requisite yielding or resilient qualities are imparted to the fingers to permit them to yield to the needle, and thus obviate the presentation of any objectional frictional resistance to the passage of the needle between the same. The finger 14 is secured to the shank-member 15, near its upper end, and thence converges downward on a curve and bears upon the upper edges ofthe stripping-fingers contiguous to their outer ends. The said .finger 14 vis yielding in character, and its forward or free end is adapted to bear against the rear curved edge of the needle, and thus strip therefrom any material which may cling thereto, while the stripping-fingers 13 operate positively to clear the sides of the needle of such material.

In the operation of the grain-binder the needle alternately projects and recedes between the fingers 13 and 14, and any matter that may have clung thereto may be readily stripped off, keeping the' needle clean, and thus in condition promptly to perform the functions designed.

While the device of this invention is exceedingly simple in construction, it will be found of the highest efficiency and durability in use and may readilybe attached to a grainbinder without requiring any change in the structural arrangement of the latter. The particular manner of attaching the shank to the grain-binder as herein shown is one of many that may be adopted, and for this reason it is to be understood that the invention is not to be limited to the precise arrangement exhibited.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A device of the class described comprising an attaching member, lateral resilient strippinglingers, and a superposed stripping-finger of less length than the lateral fingers.

2. A device of the class described comprising an attaching member, a pair of lateral stripping-fingers secured thereto and converging toward their free ends, and asuperposed stripping-finger bearing upon the first-named fingers and of less length than the same.

3. A device of the character specified coinprising an approximately inverted-L-shaped shank having means for attachment to a grain-binder, a pair of lateral stripping-fingers having their terminals in contact, and a superposed stripping-finger attached to the shank and bearing upon the upper edges of the rst-named lingers and of less length than the same.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

FRANKLIN B. STOUT.
