EBENEZER DANFORD, JR., OE GENEVA, ILLINOIS.
IMPROVEMENT IN GRAlN-HARVESTERS Specification forming part of Letters Patent No. 7.649, dated September 17, i850.
To all whom it may concern:
Be it known that I, EBENEZER Dauronn, Jr., of Geneva, in the county of Kane and v State of Illinois, have invented a new and Improved Mode of Cutting Grain and Grass; and 1 do hereby declare that the following is a full and exact description thereof, reference being had to-the accompanying drawings, and to the letters of reference marked thereon.
The nature of my invention consistsin the application of, two sickles to a reaping and mowing machine, working together itroppo site directions-atthe same time, so as to throw the weight of the moving parts upon opposite sides of the center of the crank-orbit.
,To enable others skilled in the art tomake and use my invention, I will proceed to describe its construction and operation.
'1]. construct my reaper in any of the known forms, of which Figure l in the accompany ingdrawings is a suitable and convenient one. To this I attach two'sickles by means of sickle-case. Fig. 3 in, the accompanying drawings is an end view of sickle-case, sickles', and sickle= -rods in a proper form for use, and as applied to timber g in Fig. 1.
Letter t in Fig. 1 represents a top 'view of -cap to sickle-case, beveled upon its front edge,
so as to admit of the grain passing easily iron or any suitable material.
Fig.4in the accompanying drawings isa top view of a detached sickle. The sickles are made of cast-steel plate, the width of "which is from *four to five inches, the teeth being-cut in the front edge, which are two anda half inches in len'gth,-and.may be varied to suit circumstances. The length'of' sickle is five feet, ,or corresponding to the length of platform. oneupon the-other, and work face to face.
The'irpper teeth are beveled upon the upper side and the lower ones upon the under side,
sons to form a shear cutting-ed'ge. l
Letter a in .Fig. 4represents an iron rod riveted to sickle plate,'des igned to guide the sickle and aftbrd a coupling-fork upon its'end, as shown in Fig. -1, letter '0.
The advantages of this peculiar arrange ment over single crank and sickle reapers are as follows:
First. Cutting upon both sides of the grain or grass with an equal force at the same time.
For instance, in cutting metallicsubstances with shears, where one blade is stationar-y' and-the other operating, it will, be seen that at least two-thirds of the cutting isperformed by the moving blade, whereas if the power is equally exerted upon both blades at the same time, (as in the above arrangement upon both sickles,) the cutting is equally performed by each blade, thereby making a more natural andasy cut.
Second. By obviating all lateral or side shake upon machine or horses, the weight of the moving parts being thrown upon opposite sides of the center of the crank-orbit.
Third. The ability by this arrangement to.
wield a snfiicient weight of sickle (with the same speed) to pass through and cut success fully grass where it yields from 'two' to fourtons to the acre, and overcome variousimpedimentssuch as cornstalks, large weeds, matted spots of grass, and small bushes' which are found more or less in every harvest-ficld. The sickles 1 use for this purpose weigh from ten to twelve pounds each, and when applied to the double crank overcome the above obstacles with perfect ease and success and without producing any lateral shock or vibration, one sickle balancing the other,
whereas in the application of the same weight of sickle to a single'crank of the same length of lever the lateral shock upon the machine and horses would be such as to renderits use almost impracticable. The greatest obj ections urged against single crank and sickle reapers are the constant wear, tear, and breaking of crank and crank-fastenings, a severe andi'n} The sickles are placed jurious lateral shock upon machine and knees of horses, which difficulties are almost wholly obviated in theabove arrangement.
What I claim as my invention, and desire to secure by Letters Patent, is'- The application to a reaping and mowing machine of two sickles, working together in opposite directions, as set forth in the above specification and accompanying drawings, so as to throw the weight of the moving parts npon opposite sides of the center of the crankorhit, for. the purposes set forth.
