Specification of Letters Patent.
catentea May 29, 1906.
Application filed November 21,1904. Serial No. 233.552.
To @ZZ whom, t may con/cern; i
Be it known that I, FRANK HAMACHEK, residing in Kewaunee, in the county of Kewaunee and State of Wisconsin, have invented new and useful Improvements in Guard- Fingers for Mowers or Reapers, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.
This invention relates to guard-fingers for mowers or harvesters, and has for its object to provide a guard-finger which will pick up fallen or lodged grain or vines and forcibly draw them into engagement with the cutting teeth and over the cutter-bar.
Another object of this invention is to provide a guard-finger with a toothed chain conw veyer for the above-mentioned purpose and to furnish in connection therewith a means for clearing the conveyer of the grain or vines when they have been carried beyond the cutter-bar.
A further object is to produce a casing for such a conveyer guard-finger to protect they moving parts thereof from entanglement with the grain or vines.
With Vthe above and other objects in view the invention consists in the devices and,y parts and their equivalents, as hereinafter more fully set forth. 5
Referring to the accompanying drawings, in which like characters of reference indicate the same parts in the different views, Figure `1 is a side elevation, partly in section, of a` guard-finger emboding the present invention.1
Fig. 2 is a plan view of a portion of a cutter bar provided with the guard-finger shown"y in Fig. 1, the upper section of the casing being sectioned and the chain conveyer being removed therefrom; and Fig. 3 is a tranverse section-al view of the body portion and the guard-shell, taken on the line 3 3 of Fig. 1.
In the drawings, 5 represents the fingerbar, constituting a support for the guardfingers, of which some may be constructed in accordance with the present invention and others, such as guard-lingers 6, may be of different constructions.
With the guard-finger of the present in vention there is a body portion or casing 7, which is rabbeted at its rear upper edge to iit against the 'linger-bar 5 and bear on the front edge thereof with its upwardly-extending shoulder 8 formed by the rabbet. The rear end of the body portion 7 is secured to the finger-bar 5 by means of a bolt 9, passing therethrough and having its nut beneath located between a pair of downwardly-exm tending side fianges 10 of the body portion 7, which merge with the rounded central portion 11 thereof and together form a runner or bearing surface to slide upon the ground. The side flanges 10 on either side of the nut of the bolt 9 being lower than the end of the bolt, prevent said bolt engaging the ground. In the top of the body portion 7, just in advance of the linger-bar 5, is a transverse groove 12, through which slides a sickle-bar 13, carrying its cutting-teeth 14 in the usual manner and bearing upon an angular bearing-plate 15, held to the top of the finger-bar 5 by means of the'bolts 9 and taking the rear thrust of the sickle-bar. In front of the slot 12 and forming one wall thereof is a transverse upwardly-extending iiange 16, in alinement withv which extend lateral spacing-arms 17 on either side ofthe body portion to abut against similar spacing-arms on the adjacent guard-ngers and serve to hold the several guard-'fingers in their proper position. In advance of the flange 16 is a pocket or recess 18 with an overhanging upper wall 19, which with the slotted side walls of said pocket forms a guard for the cutting-teeth. Vith its point contained within said pocket and its cutting edges passing out through said slots, the stationary cutting-tooth 20, having the upper cutting-tooth 14 resting thereupon, is secured to the upper surface of the'iiange 16 by means of a rivet which passes vertically through said cutting-tooth and the flange 16 to the space between the depending flanges 10 underneath the body portion. The front end of the bearing-surface 11 is drawn to a point and is made comparatively thick, and at the side edges of the body portion '7 are upwardly-eXtending Walls 21 with their edges inclining from the pointed front end of said portion 7 and forming between them the lower section of ,a casing for containing moving parts to be later described.
Journaled across the lower section of the casing, with its bearings in the parallel side walls 21 thereof, is a small roller 22, and mounted on a suitably-driven hollow vshaft 23, above and in the rear of the cutting mech` anism, is a sprocket-wheel 24. Traveling around the roller 22 and the sprocket-wheel 24. is an endless conveyer-chain 25, having outwardlyeprojecting engagingteethv 26 on IOO the side members of some or its links. J ust in advance of the roller 22 the bottom wall of the body portion 7 is indented upwardly to form a rounded cam projection in front ofsaid roller to prevent the vines or grain starting in beneath said roller and causing them to pass in a position to be engaged by the teeth 26 of the conveyer-chain. The shaft 23 is considerably higher than the roller 22 and rotates in a direction to cause the chain to travel, with its upwardly-extending teeth 26, from the roller 22 at quite an incline to the top of the sprocket-wheel 24.
In order that the material being carried by the conveyer-chain 25 cannot fall beneath the upper length of said chain and become entangled in the moving parts, a tapering shell 27, U-shaped in cross-section, with its lower edges passing between the upper edges of the vertical side walls 2l, is secured to said vertical walls by means of bolts 28, extending across the casing formed between these parts and through the edges of said side walls and shell, threading into one of the side walls 2l. At its ends the shell 27 is slotted to permit of the passing of the roller 22 and the teeth of the sprocket-wheel 24, respectively, and is curved at the side portions to conform as nearly as possible to the shape of these parts. The upper wall of the shell 27 extends in line with the travel of the upper length of the conveyer-chain just beneath the same, so that there is no opportunity for the grain or vines finding their way beneath the chain conveyer and becoming entangled with the sprocketwheel. Grain or vines being carried up by the conveyer-chain 26 are removed therefrom when cut by the cutter-bar by means of clearing-wheels 29, mounted on the shaft 23 above the guard-finger 6 on either side of the sprocket-wheel 24 and provided with pairs of radial fingers 30, which in their rotation lift the grain and vines from the conveyer-chain 26 and the cutting mechanism and dump them in the rear of the cutter-bar.
In order to remove from the sprocketwheel 24 and the clearing-wheels 29 any grain or vines which may become caught therein, a series of plates having inclined spring stripping-fingers 31 are provided to bear upon the shaft 23 between the sprocketwheel 24 and the clearing-wheels 29 and upon the clearing-wheels 29 between the pairs of fingers thereof. The plates, with the spring stripping-lingers 31, are secured to an inclined strip 82, extending parallel with the cutterbar at the rear thereof and which is supported thereby vin any suitable manner, preferably by means of brackets 33 on the guard-ingers 6 at each side of the conveying guard-linger of this invention, as shown.
From the foregoing it will be seen that in operation the guard-finger of this invention bears upon the ground at the front and rear portions without presenting an exposed projection capable of being caught in and held by obstructions or of gathering accumulations to constitute obstructions to the proper operation of the device. The forward end is pointed and slightly raised from the ground, so as to pass beneath the low-lying grainor vines without digging into the dirt, and having passed therebeneath the inclined edges of the side walls 2l raise the said grainv or vines until they are engaged by the teeth 26 of the conveyer-chain 25. As this chain moves at such a speed as to carry the grain or vines to the rear faster than the machine moves forward, the grain or vines will be quickly lifted considerably in advance of the cutter-bar, so that by the time the cutter-bar is brought into engagement therewith the heads of the grain or the seed-pods of the vines will be elevated above the plane of said cutter-bar and will not be severed thereby. By this operation grain or vines lying in the direction of travel of the machine will be lifted and cut properly.
The casing for the moving parts of the conveyer, formed by the shell 27 and the side walls 21, whereby only the rearwardly-traveling upper length of the chain is exposed to engagement with the grain or vines, prevents the entanglement of the grain and vines with such moving parts and especially avoids the falling of the grain-heads and the vine seedpods into the space between the upper and lower lengths of the conveyer-chain, where they would become separated andlost by being cut by the sprocket-wheel and chain in their operation.
The grain and vines are prevented from returningwith the chain to the front end of the guard-iinger'by means of the clearing-wheels 29, which lift them from the conveyer-chain as soon as they are cut and deposit them upon the inclined spring stripping-fingers 31, from which they slide to the ground at the rear of `the cutter-bar. The spring-fingers 3l, pressing upon the shaft 32 and the clearing-wheels 29, prevent the vines or grain being wound thereon or entangled therewith, and so keep these parts clear of all obstruction.
It is obvious that with guard-fingers of the construction herein shown and described all possibility of the cutter-bar becoming clogged and obstructed is prevented, for the materials as soon as cut are carried over the cutter-bar and discharged therebehind.
It is apparent that vby the construction employed with this invention the conveying feature is accomplished without materially altering the proportions of the guard-fingers and without presenting engaging parts for accumulating obstructions to the proper operation of the device. Further, the construction of this invention does not necessitate the alteration of the remainder ofthe cutter-bar but, on the other hand, this guard-linger IIO IIE
-TSO
may be interchangeable With the ordinary forms of guard-fingers, so that they may be sulstituted therefor or replaced thereby at W1 While the particular details of construction and arrangement of parts as here shown and described are at present preferred for the accomplishment of the objects of thisinvention, it is obvious that numerous alterations and modifications may be made therein Without departing from the spirit and scope of the invention as claimed.
Though the finger-guard is herein described as attached to the finger-bar of the cutting mechanism, it is obvious that should it be found desirable to mount it in any other manner this may be done Without materially affecting its operation, and therefore Without de arting from the invention.
