o all 'whom 'it 'may concern:

Beit known that I, JEREMIAH W. MULLEY, of Amsterdam, in the county of Montgomery and State of New York, have invented a new and useful Improvement in Mowing and Reaping Machines; and I do hereby declare that the following is a full and clear description thereof, reference being had to the accompanying` drawings, which form part of this specification, and in which- Figures land 2 represent opposite side elevations of a machine with my improvement applied to it; Fig. 3, a plan view thereof; and Figs. 4 and 5, a partial plan and sectional elevation, on alarger scale, ofthe tin ger and cutter portion of the machine, to which part my present improvement relates.

In this myimprovement the cutter is shown to occupy its ordinary position in front of the machine for reciprocation across the traverse The means for reciprocating the cutter may be varied. It is therefore unnecessary here to refer to any particular ones, nor vet to describe the general form of the cutter and connection with the fingers, or relative arrangement of the latter, asl thoseacquainted with harvesters generally need no such de-A scription of parts that are common, anymore than they do ofthe peculiar functions of' such devices. I will therefore merely preface the description of my improvement by saying that I adopt that previously-known style of reciprocatingcutter the peculiarity of which consists in the employment of a series of projecting blades formed to cut on either of their projecting edges, and secured at a suitable distance from their points or fronts to a cutterbar that may be guided by traversingit through slots in the fingers, which latter are also usually slotted in front to receive through them the projecting blades that effect the out, said blades being generally of a V shape or sawtooth form, and said fingers secured to or held down by a bar in the rear. This preface will more clearly explain what is new and useful in the sequel and render a lengthy description superfluous.

Referring to the accompanying drawings, or more particularly t0 Figs. 4t and 5 thereof, the fingers A may be of the usual or any other suitable general configuration; but as here shown I make them with'lateral projecting lips a a in front and in rear of t'he slots I) in the lingers through which the cutter-bar B in its reciprocating action plays or is guided. By these lips being arranged to form lateral continuations to the back and front sides or edges of said slots, they thus serve not merely to stiffen the fingers where the slots weaken them, but, without adding materially to weight and avoiding objectionable thickness of the fingers, also serve to give a wide and steady bearing to the cutter-bar at its edges, and to diminish or more generally distribute wear by the increase in length or width given to the cutter-bar and finger surfaces comingor thrown in contact by forward and backward thrust or pressure. By such construction,too, the liability to breakage is diminished, and the iingers generally may be constructed narrower or lighter. I also make the rear portion ot' the iingerswith aswell or convex upper projection, c, that not simply serves to stiften the fingers at their roots, but forms a bearing for the finger-bar C to both hold down the ngers and also more securely restrain them from moving forward and backward, and that admits of my using a linger-bar made of sheet-iron and bent longitudinally into a curved or arched form, and which combines stiffness with lightness and does away with objectionable abruptness of top surface. "lheconcave side of .this bar G being laid on the convex projections c of the fingers, bolts d may be passed through the bar and fingersto draw and hold vthem together; and the finger-bar may be secured to the machine in any suitable manner.

0n the upper side or face of the cutter-bar B arethe cutters c. steel blades, of V shapeor saw-tooth form in front, sharpened on bot-l1 sides or edges, but presenting straight and parallel (or thereabout) sides at theiry bodies or rear portions, and preferably a straight line or edge at theirV backs. Said blades maybe secured to the cutter-bar B by bolts or screws f, that may unite the blades to the bar at or about the center in width of the former, and which will admit ofV These cutters may be whenthus or otherwise equivalently or suitably held to the cutter-bar, from Workingloose or turning, and in turning and rising riding one over the other, or, in other Words, to effect the lateral adjustment and hold of these blades, I

-form these several adjacent sides or edges of the bodies of the blades with notches s s, arranged to face each other, and of semicircular orother suitable shape, to receive within them lrivets or pins r, or their equivalent, attached to or connected with the cutter-bar, by which means I effectually lock the several blades togetherfrom lateral action or twist individually, and steady their hold generally Without im pedin g their attachment or detachment to or from the cutterbar, when required. |Ilhe pins r, that tit'in the side notches of the blades, also serve to take o' strain from the screws f in effecting the recipy rocation of the cutter.

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

1. The manner herein described of securing the'detachable cutters or blades to or in their place on the cutter-bar, and relatively to each other, by means of central holding-screws, in combination with pins or studs on the bar to tit the recesses in the adjoining sides ofthe blades, substantially as set forth.

2. Providing the fingers with the laterallyprojecting lips in front and rear ot' the slot in which the cutter-bar plays, substantially in the manner and'for the purposes specified.

3. The finger-bar, arched as describeiihin combination with the lingers made with a swell or convex projection in their rear, substantially as herein set forth.

In testimony whereof I have hereunto subscribed my name in presence of two witnesses.
