DOUBLE CUTTER-BAR FOR HEADERS.
SPECIFICATION forming part of Letters iatent No. 443,002, dated December 16, 1890.
Application filed September 28, 1889. $erial N0. 325,36L (N0 model.)
To all whom it may concern.-
Be it known that we, CHARLES E. PLUM- TREE and LOUIS A. A. TONNE'F, both of Spokane Falls, in the county of Spokane and State of \Vashington, have invented a new and Improved Reciprocating Double Cutter- Bar, of which the following is a full, clear, and exact description.
This invention relates to headers, the main object of the invention being to provide such machines with a double cutter-bar; and to the end named the invention consists of certain novel constructions, arrangements, and combinations of elements as will be hereinafter described, and specificallypointed out in the claims.
Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar figures of reference indicate corresponding; parts in all the views.
Figure 1 is a plan view of our improved double cutter-bar for headers. Fig. 2 is a side view upon an enlarged scale; and Fig. is a plan view, parts being broken away.
In the drawings, 10 represents the fingerbar, which is provided with forwardly-extending fingers I 1, said fingers being supported and braced by longitudinal strips in the ordinary manner-such, for instance, as illustrated in my application, Serial No. 325,360, filed concurrently with the present application.
12 and 12 indicate respectively the upper and lower cutter-bars. The operating-lever of the lower cutter-bar 12 is formed of the two sections or members 1t 17 which are connected at their adjacent ends by means of a slide 16, that is pivoted on the member 17 and engaged by the forked end of the member 14. Near its forked end the member 1i is pivoted on 'a fixed pivot-pin 15, and the member 1'7 is pivoted near its slide 16 on a fixed pivot-pin 18, and is connected at its opposite end to the pitman or connectingrod 20. The upper cutter-bar 19. is connected to one end of a lever 22, the opposite end of which lever is forked and engages a slide 21, which is pivoted to a pivot-pin 25, carried by the lever 17, adjacent to that end of the lever 1'7 to which the pitman 20 is connected. The lever 22 is fulcrumed on the pivot 15, and is approximately of a length equal to the combined length of thetwo-part lever 11 17. The relative length of the members 14 17 and the location of their pivot-s are such as to give the member 14 the same throw as that of, the lever 22, whereby bot-h the upper and lower cutter-bars will be reciprocated a like extent, but in opposite directions.
Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The combination, with double cutterbars, of a pitinan connected with a lever and operating one of the cutter-bars, and a second lever operating the other cutter-bar and formed of two members that are united by a sliding connection, each of the members having a separate fulcrum, the said two-part le- Ver being connected to and operated from the first-named lever.
2. In a harvestingmachine, the combination, with the cutter- bars 12 and 12, of a lever 11, connected to the cutter=bar 12, a lever 17, a slide 16, to which the lever 17 is connected, which said slide engages the lever 14., a lever 22, that is connected with the cutterbar 12, a slide 24, carried by the lever 17 and arranged to be engaged by the lever and a means for rocking the lever 17, substantially as described.
