UNITED STATES PATENT OFFICE.
I HENRY F. sHAw,'oF wEsT ROXRURY, AssIGNoR To JAMES A. wooDBURY,
OF BOSTON, MASSAGE USETTS.
l IMPROVEMENT IN CUTTING APPARATUS FOR MOWING-MACHINIES.V
Specification forming part of Letters Patent No. 104,364, dated J une.14, 1870.
To all whom it may concern:
I, HENRY F. SHAW, of West Roxbury, in `the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Mowing-Machines, of which the following is a specification:
I The Nature and Object of the Invent/ion..
. The nature of my invention consists in a new and peculiar device for operating the cutterbar of a mowing-machine, the device being to operate the cutter-bar by means of two pitmen,
which `are attached to two cranks set diametrically opposite each other, one of the pitmen with a cutter-balance or slide upon the cutter- Ibar through an intervening lever, the object of the invention being to concentrate the effect of the action and reaction due to the motion and work of the cutter-bar upon the same pointth at is, upon the driving-shaft-and to balance the same, so that the body of the machine shall be freed from vibration.
` Description of the Accompanying Drawings.
\ Figure lis a perspective view illustrating my invention. Fig. 2 is a plan of the same.
General Description.
B represents the driving-shaft, which is provided with two cranks, D and D', these cranks being set diametrically opposite to each other, and serve to operate the two pitmen H and E.
The pitman H acts directly on the cutterbar K in the usual manner, while the pitlnan E, always moving in the opposite direction, acts through the counter-balance slide P and thelever L, the lever L having its fulcrum at M.
By this arrangement of uniting two pitmen which operate in different directions any strain on the cutter-bar will be divided, so that one half of it will act upon the driving-shaft in one direction, while the other half will act upon the driving-shaft in the opposite direction, while the effect due to momentum of the cutterbar will be balanced by the balance-slide P, so that any strain, either of momentum or work, will exactly counterbalance itself on the driving-shaft.
I claim as my invention- The combination of thedouble crank D D',
vthe pitmen H and E, the lever L, and balance P with the cutter-bar K, operating as described, and for the purpose set forth.
Witnesses: HENRY F. SHAW.
