MOWINGWIVIACHINE Specification of Letters Patent.

Patented Sept. 18, 1906.

Application filed December 28, 1903. Serial No. 186.816.

T0 .1. whom it may concern.-

Be it known that I, IWAN LATYSCHEW, a subject of the Czar of Russia, residing at Moscow, Russia, have invented certain new and useful Improvements in Mowing-Machines, of which the following is a specification.

This invention relates to an improvement in hand mowingmachines, or more particularly to improved knives used for such machines whatever their construction may be.

The improvement consists in that oscillating knives are pivoted with their points to the points of fixed knives to enable corn or the like to be out between the oscillating and the fixed knives. The oscillating knives are fixed at their other end to a common connect'ing-rod.

Though a combination of oscillating and fixed knives has already been employed for the cutting of corn and the like, the former constructions differ considerably from mine, the knives not being pivoted at their points. The peculiar combination of the knives according to my invention prevents the knives bending or deforming in cutting corn that differs in thickness or that stands denser in some parts of the field to be out than in others, so that the number of stalks to be out between each set of knives varies. Thus I prevent the stalks being bent or pinched between the knives instead of being out.

In order that this invention may be the better understood, I now proceed to describe it, reference being had to the accompanying drawings, and to the letters marked thereon.

Like letters refer to like parts in the various figures.

Figure 1 is a view from below of the knives at the completion of an oscillation or cutting movement. Fig. 2 is a similar view showing the parts in mid-position. Fig. 3 shows the knives at the initial position of their cutting action; Fig. 4, the combination of knives when they have been drawn out for the purpose of cleaning or sharpening;

Fig. 5, a form of construction in which the cutting edges of the fixed knives are arranged somewhat differently.

The combination consists of a number of fixed knives 6, formed out of the single plate 0, and the same number of oscillating knives f. The knives f are pivoted with their points to the points of the fixed knives 6, while the opposite and broader end is linked or pivoted to a rod g. Said rod is pivoted to another rod 1, which in its turn is linked to a crank h, that may be moved in any suitable manner-for instance, by the bevel-gearing n and 0. The edges of the knives f and the plate 0 (knives e) are sharpened in their cutting part. In cutting the bevel-gearing n, 0 moves the crank, which movement is transferred by the rodL to the rod g, thus oscillating the knives f to and fro.

The construction of Fig. 5 only differs from the one described in the following detail: No oscillating knife is pivoted to the central fixed knife, in consequence of which the central fixed knife has a cutting edge on each side.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a hand mowing-machine the combination of fixed knives and oscillating knives, pivoted to one another at their points, and means for oscillating said knives, substanti ally as described.

2. In a hand mowing-machine the combination of fixed knives and oscillating knives, pivoted to one another at their points, a rod guided to reciprocate relative thereto, the opposite ends of the oscillating knives being pivoted to said rod, and means for actuating said rod, substantially as described.

3. In a hand mowing-machine the combination of fixed knives and oscillating knives, pivoted to one another at their points, a rod to which the opposite ends of the oscillating knives are pivoted, the central fixed knife having two sharp cutting edges, and means for actuating said rod, substantially as described.

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

IWAN LATYSOHEW.

Witnesses I SERGEI KONENKOFF, VETscI-IEsLAFF SEMENoFF.
