DIVISION A.

To all whom it may concern: Be it known that I, E. BALL, of Canton, i the county of Stark and State of Ohio, have invented certain new and useful Improvements in Grain and Grass Harvesters, better known as Balls Improved Ohio Mowerg7 and I do hereby declare that the followin gis afull,clear, and sufcient description thereof, reference being had to the annexed drawings, making part of the same, of which- `Figure lis a side view of my machine. Fig. 2 is a rear view of the same. Fig. 3 is a plan or top View of the same. Fig. 4 is a detached view of one of the pinions and a portion of one of the spur-wheels, pawl and ratchet of the pinion being shown. Fig. 5 is a detached plan or top view of one of the pinions.

In the accompanying drawings, A represents the frame of the machine, which is of rectangular form, and is supported by two independent driving and supporting wheels B B', with separate axles C and C'. Spur-w heels .D D' are secured to the inner sides of the spokes ot' the wheels B B' and gear into pinions ,E E', which play loosely on the ends of a horizontal shaft, F, which runs in suitable bearings, a a', on the frame A.

To the shaft F there are permanently secured two caps or cases, G G', within each of lwhich a'pawl, b, is secured, and these catch into ratchet-teeth H, which are attached to the inner sides of the pinions E E'. (See Figs. 4 and 5.) The pawls have small springs c directly over them-one over each-whichkeeps them in the ratchet-teeth, while the cases Gr G" exclude dirt and cut stalks of grain or grass from interfering with the proper action of the ratchet-teeth and pawls.

I is a bevel-toothed wheel securely attached to the shaft F, and gears into a bevel-pinion, J, at the' upper end, of the inclined crankshaft K, which runs in suitable bearings, d d, attached tothe underside of the frame A and below the axial line of the wheels B B'.

Directly back of the pinion J, on the shaft K, there is a fly-wheel or balance, L, which serves to preventlittle irregularities in the action of the machine or of its wheels from at' fecting the action of the sickle. -At the lower end of the shaft there is a crank-pulley, M, to which one end ot' a connecting-rod, N, is attached, the opposite end being pivoted to a sickle, O', working between fingers c e upon the finger-bar I).

To the inner end of the lnger-bar P there is rigidly secured at right angles thereto an inclined wide iat plate or bar, Q, the upper end of which is attached to a wrist 0r swivel, f, by pivot g, forming a joint or hinge, the wrist f being itself secured within a cylindrical socket, h, by a nut, h', which screws upon the end of said wrist, as seen at Fig. l.

To the lower end of the plate or bar Q, which serves the purpose of a shoe to support the heel of the linger-bar, a brace or coupling arm, B, is connected bya pivot, j, the outer end of said brace or coupling-arm being attached to a hanger depending from the back partoi` the frame A by a pivot, lr.

As the machine is drawn along by the rigid draft-pole A the driving-wheels B B move in the direction indicated by arrow 1, (see Fig. 4,) and the spur-wheelsD D', moving in the same direction, cause the pinions E E to move in the direction of arrow l'. The ratchet-teeth H, catching against the pawls b, cause the shaft F to rotate, and motion is thereby communicated to the sickle 0 through the shaft the linger-.bar and bar Q to rise and fall bodily,

and the ability of the rodfto turn in the socket li permitting either end to rise and fall, while the bracerod R serves to steady the linger-bar while it is moved, and to prevent it from being wrenched out of place by the resistance of the grass or of obstacles, and thus the fingerbar is under all circumstances at liberty to conform to the unevenness of vthe ground, and consequently the sickle will perform its work better and with greater uniformity than it otherwise could do.

My machineis well adapted for use on rough i land, and in case small obstructions should present themselves inthe path of the inner shoe when the finger-beam is raised at its outer end no injury is liable'to result to the machine, since the iiexible nature of the joints of the 'couplingarnn together with the jointsot' the brace Q, (or its equivalent permits the heel of the finger-beam and inner shoe to rise and fall, to pass over the obstructions, or conform to the inequalities of the ground. The connections ot the ngenbeam are also such that,

when necessary, the finger-beam can be rst v raised up bodily and then the outer end turned up at an angle of about forty degrees by hand or by an attendant upon the ground.

In a grain and grass harvester great strain comes upon the finger-beam, and it is important that it should be attached by means having sufficient strength to resist any sudden strain, and for this purpose the coupling-arm is hinged to the frame or something attached thereto,while the finger-beam is firmly attached to the rear end of bar Q, which is hinged to the front of the machine, so that any sudden strain exerted on the ingerbeam in turning the machine or otherwise is borne by the connections both in front and rear of the axial line ofthe main wheels.

To obvia-te the danger of throwing the guardfingers out of their proper and relative position as respects the critters, I hinge the couplingarm to the main frame in the same or nearly' the same vertical plane with the center of the crank-shaft, while the other end is hinged to the lower end of the brace or plate Q, (which serves the purpose of ashoe,) while the forward hinged connection is such that the motion of the finger-beam, when the outer` end only is raised above the inner end, shall be in the arc of a circle the center of'which shall be in a line parallel to the line of motion of the masaid plate so as to connect it with the front of the machine by a joint, so that the draft of the finger beam and cutting apparatus is through a connection attached to the front of themachine and forward of the driving-wheels and fingerbeam- As the coupling-arm It is liable to sudden strains, I hinge it directly to the lower end of the bar or plate Q, which serves the purpose of a shoe, by means of two lugs rising up through the top or cap plate, P', so thatit has adurablevconnection, which is not liable to be broken off or become loose.

I usually turn my machine, when cutting grain or grass, next to the fence, so that the wheel B remains stationary, or has but little motion while turning corners, and if the wheel B were rigidly attached to the same shaft there would not only be a great difficulty in turning, but the machine would be liable to be wrenched, while the cutters would be sure to get clogged. To obviate these difficulties I employ an independent supporting and driving wheel, B', so that while the side of the machine next the short finger-beam is well sustained the cutters are driven at a sufficient velocity while turning corners on uneven ground, or to pass obstructions to do good work, and thus prevent all clogging, which is sure to result from a slow or no motion of the cutters when the finger-beam is moved forward.

By the use of two independent supporting and driving wheels, in combination withaiinger-bar connected as described, either of the wheels can rise or fall without affecting the movements of the finger-bar or of seriously interfering with the cutting apparatus, for if one Wheel happens to drop into a hole the other wheel continues to operate the cutters; or if one wheel strikes suddenly a stone or stump, as is often the case, with such force as to stop the wheel and turn the machine to one side, still the cutters are worked by the other wheel. When both Wheels are worked t0- gether a very powerful stroke of the cutters is obtained, and although it is necessary to run the crank-shaft at a very high velocity, I avoid jarring and wrenching of the machine by arranging the crank-shaft below the axial lineof the main wheels, below the main frame, and between the driving-wheels, and gear to one end of it and on one side of the axle of the supporting-wheels, while the pitman is connected to the other end and on the opposite side of the axial line of the supportingwheels. l

The plate Q, the lower end of which serves the purpose of a shoe and support to the iinger-beam, being hinged at its forward end, so that it can rise and fall and also turn, passes over obstructions much easier than it would if it could notyield, while the action of the machine is much more uniform than it would be it' it were to be tipped back and forth by every little obstruction which happened to be in the path of the shoe part of plate Q.

It will-be observed that the arrangement and construction of the various parts of the machine are such that no part of the machine is liable to catchthe cut stalks either in rear mm @wm PTO BoYERs, PQ Dufgsffian MISSING PAGE TEMPORARY NOTICE PATENT HAS BEEN SCANNED, BUT WITH MISSING PAGE(S) u FOR ISSUE DATEl/-w/ UPON RECEIVING OF MISSING PAGE(S), THE ENTIRE DOCUMENT WILL RE RESCANNED.
