IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 111,424, dated January 31, 1871; reissue No. 5,316, dated March 11, 1873.

To all whom it lmay concern Beit known that I, LINDLEY M. BATTY, of Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Harvesters, of which the following is a specification:

The first part of my invention relates to that class of machines having a metal frame.

lts object is to secure a strong, light, andV rigid frame, and to protect the gearing from dust and dirt, to which end the improvement consists, first, in constructing the main frame of a harvester of a metal base-plate having a down-hanger cast at one end for the journal of the crank-shaft and a cavity for the gearing on one side, (the walls of said cavity bein g either entirely cast or having one side of sheet metal,) and all the bearings of the gearing being cast withthe base-plate and the gearing completely inelosed by suitable coverin gs combined with the base-plate, as hereinafter more fully set forth. Second, the next part of my invention relates to machines having backing-ratchets. Its object is to afford additional bearing-surface for the main axle, to lessen the danger of splitting the hub by strains on the driving-wheel, to which end my improvement consists in combining a driving-wheel having notches on the interior of its hub at such distances apart as to leave from one-fourth to one-half of its surface unnotched, and a pawl-wheel fitting in said hub with its rim bearing against said unnotched portions, as hereinafter more fully set forth. Third, the next part of my invention relates to the gearing. Its object is to guard against injury to the driver and to enable him to throw the mechanism into or out of gear, which objects I attain by combining with the gearing mechanism by which the driver keeps the machine in gear by bearing with his foot upon a treadle, the gearing being at once disconnected by the removal of his foot from the treadle, as hereinafter more fully set forth. Fourth, the next part of my invention relates to the lifting-lever. Its object is to obtain a cheap, simple, and eficient device by which the driver can simultaneously operate the lifting-lever and its locking-pawl, to whichend the improvement consists in combining with the lifting-lever a coiled-wire handle connected with the locking-pawl, as hereinafter more fully set forth. Fifth, the next part of my invention relates to that class of hinge-joint harvesters having a double-hinged couplingframe rocking in its connections with the main frame to regulate the pitch of the guards and secure a compact arrangement of mechanism; and the improvement consists in combining, with the main frame of a harvester, a coupling-frame pivoted on a longitudinal axis between the driving-wheels, and having suitable rocking mechanism, as hereinafter more fully set forth. Sixth, the next part ofmy invention relates to the construction of the coupling-frame. Its object is to make said frame light but rigid; to which end the improvement consists in lconstructing the couplingframe of a single bar of wrought metal having its ends bent so as to cross each other, and being firmly secured together at their joint of junction, as hereinafter more fully set forth. Seventh, the next part of my invention relates to the hinge-connections between the coupling-frame and shoe. Its object is to enable the finger-beam not only to rise and fall at either end, but to fold up and be turned around parallel to the face of the driving-wheels for convenience in tran sportation, to which end the improvement consists in combining the inner shoe with the coupling-frame by a swivelingjoint at one end and an intermediate arm at the other, pivoted to the shoe jand secured to the coupling-frame by a detachable connection, as hereinafter more fully set forth. Eighth, my invention further consists in combining a main frame, a vibrating coupling-frame hinged thereto, a guard-shoe secured to said coupling-frame, and an inner shoe (carrying the finger-beam) hinged to the guard-shoe.

"In the accompanying drawing, all my improvements are represented as embodied in one machine; obviously, however, some of them may bel used Without the others, and in machines differing lsomewhat in construction fromthe one shown.

Figure 1 represents a plan or 'top view of so casing broken away to'show the mechanism. beneath; Fig. 2, a rear elevation of portions of the machine; Fig. 3, a side elevation of the' machine; Fig. 4, a vertical longitudinal section through the frame on the line w w of Fig. l; Fig. 5, a detail of the clutch mechanism; Figs. 6 and 7, views of the ratchet-hub; and Fig. 8, a side view of, and transverse section through, the sliding spur-pinion on the counter-shaft.

Two main driving-wheels, A A', are shown as turning freely on a main axle, B, with which they are connected by backing ratchets, hereinafter described. The main axle in turn revolves in bearings in the main frame, which consists of a base-plate, C, having a stirrup or downhanger, C1, at one end for the journals of the-.crankshaft and coupling-arm pivots. A

chamber, G2, Fig. 1, having two compartments,A

is formed in the base-plate, near its outer front corneriand at the adjacent side thereof, and

may either be cast in one piece with the baseplate, or it may have a removable side, C3, litting in Va groove in the base-plate. A flange, c, on the inner side of the base-plate, serves as a shield for the driver, and as a strengthening rib or brace for the frame. The. front part of this tlange also forms one side of a socket for the' tongue D. Bearings for the main axle mayv be ',cast'ineither the upper or lower side of the base-plate. A spur-wheel, B', fast on they main axle, drives a corresponding pinion, e, on a counter-shaft, e', mounted in bearings in thechamber in the base-plate, and carrying a bevel-gear, E, which drives a pinion, f, on a crank-shaft, F, whichdrives the cutters in the usual well-known way.

' The gear-chamber G2, it will be observed, is in two compartments, the one inclosing the main spur-wheel being partly above the frame, while the other (inclosing the bevel-gearing) is entirely below it. lhese compartments are inclosed by sliding or` hinged covers of wellknown construction. The gearing is thus protected, and, being mainly below the base-plate, leaves the platform of the main frame unobstructed. f

The advantages of having all the bearings ina rigid metal frame, instead-of mounting them in a yielding wooden one, are obvious; and metal frames have been v.much used in consequence.

The construction of thc frame may be modified to vsuit various classes of machines, such as front or rear cut, or double-speed gearing, as is well understood.

The mechanism is thrown into or out of gear by means of a treadle, Gr, acting on a lever, g, pivoted on the box of the countershaft, and bearing on a forked shipper, g1, pivoted underneath the base-plate and sliding the second spur-pinion e endwise. (See Figs. 4 and 5.) A spring in the spurpinion tends lto keep litin gear vby bearing against a shoulder, e', on .the counter-shaft., y A spring, g2, tendsfto keep the. mechanism out of gearby bearing down on thegtreadle. v Oonseqi 1ently, to keep it in gear,

`the driver must eitherkeep his foot on the treadle or fasten it down with a button, g4, on the frame. When-not thus fastened, should the driver be thrown from his seat the gearing would stop, and thus avoid the danger of injury from the cutters workin g.

Y The driving-wheel hubs (see Figs. 6 and 7,)

form long pipe-boxes a, ratchet-notches being formed in the inner surface thereof. A pawlwheel, b, keyed on the main axle, fits snugly in each hub, but allows the hubs to turn freely. Pawls b', pivoted in recesses in the pawlwheels, are forced outward by springs, which tend to keep the pawl in the ratchet-notches when moving forward.

The operation of the device is obvious. As the notches occupy less than one-halt' of the inner surfaceof the hub it is obvious that a large bearing-surface between the hub and pawl-wheel will be secured, thus 'preventing wearing or danger of splitting the wheel.

A frame, composed of bent cor'rugated rods `H, mounted on the frame, supports the drivers seat H by means of links h, hooked on therods and Vpivoted to the seat-standards. By this means an easy swinging motion is given to the seat, and it can readily be moved backward or forward to adjust it and retain itself in position without being fastened by the hooks catching in the corrugations of the supporting-rods.

j The coupling-frame K K for a rear-cut machine consists of a continuous bar of metal, bentin the manner shown in the drawing. A brace-rod, I, pivotedy in a swiveling socket, fi, on the down-hanger O1, extends in front of the main axle, and carries at its forward end a block, t, moving vertically in a guide, I', nnderneath the base-plate and central, or substantially so, between the wheels. A link, j,

connects this brace-rod with the cranked rockfshaft J operated by a hand-lever, J, controlled by a suitable detent. A drag-bar, K, pivoted on the frontend of the brace-rod I, with its edge vertical, extends diagonally outward and backward to aV point behind and outside ofthe inner driving-wheel A', being twisted until it lies flat. It is then bent downward, and carried forward to form the sole k of the guardshoe. The front end of this shoe is rounded. to form a socket, k1. The bar is thendoubled lback on itself to stiifenthe sole of vthe shoe;

twisted, bent upward, and forms the couplingarm K', being pivoted to the swiveling socket t', riveted to the drag-bar at their intersection, land the junction vstrengthened' by a stiieningplate, k2. An extra runner, k3, is secured to the under side of the shoe to give Vit the requisite strength and stilfness.

The coupling-frame, it will be seen, is rocked by the lever J above described. 1 It is raised ory lowered lby means of a chain, l, passing over a pulley, L1, on the frame, and attached to a rocking sector, Z2, pivoted on theframe, and controlled bya hand-lever, L. A coilediwirek handle,L`1, on the lever is connected with al pawl, Z3 alsopivoted onY the: handle, kactring on a sector-rack of ordinary construction to hold the coupling-frame at any desired elevation.

The driver can easily lift the pawl by grasping the handle and with the saine motion that operates the lever. A finger-beam, M, having the usual cutting apparatus, is secured at its heel end to a shoe, N, having lugs or sockets n on its heel and toe. A pin, n', turning in the front socket of the guard-shoe k, is pivoted to the toe of the shoe N. A short bar, O, is pivoted to the rear lug of the shoe N, and turned atwise so as to lie upon the coupling-arm, to which it is connected by a bolt, o, and by a screw, o', having a crankhandle, to admit of its being readily removed or replaced.

The operation of the machine will be obvious from the foregoing description. The iinger-beam can rise or fall freely at either or both ends without affecting the movements of the main frame. It can likewise be raised or lowered to pass obstructions or to regulate the height of cut, and can be rocked to regulate the pitch of the guards by the rocking lever. The finger-beam can be folded directly up against the main frame; or, by removing the rear hinge connections, it may be rocked on its front hinge and turned parallel with the face of the driving-wheel. By removing the front hinge and the crank-screw the cutting apparatus may be swung round horizontally parallel to the path of the machine, and thus be carried from field to field when a grain-wheel is used.

I claim as my invention- 1. The main frame, constructed as set forth, and consisting of the metal base-plate having the down-hanger cast at one end, the gearchambers and casing at the side and near the outer corner thereof, and bearings for the journals, as described.

' 2. The combination of the driving wheel hubs, notched intermittently to leave a bearing-surface on their interior, with theV pawlwheels fittingin said hubs, and carrying springpawls taking into the ratchet-notches, as described.

3. The combination of the spring-pinion sliding on the counter-shaft, the swinging shipper, the lever pivoted on the box of the countershaft, and acting upon the swinging shipper, the link, the treadle and its spring, all these members being constructed and operating in combination, as set forth, to throw the mechanism out of' gear whenever the driver releases the treadle.

4. The combination of the lifting-lever, its pawl, and the coiled-wire handle connected directly with the pawl, substantially as set forth, to enable the driver to release the pawl and move the handle by a single motion.

5. The combination, with the main frame, of the coupling-frame rocking on alongitudinal axis between the wheels, and pivoted to the main frame at one end by a swivel-joint and at the other by asliding connection, these members being constructed and operating in conlbination, as and for the purposes set forth.

6. The coupling-frame, construsted as set forth, of a continuous bar, which also consti-` tutes the guard-shoe.

7. The combination of the couplin g-frame, the guard-shoe, the inner shoe of the iin gerbeam, the swivel-pin connecting the two shoes and the intermediate arm pivoted to the inner shoe and upon the coupling-frame, these meinbers bein g constructed and operating substantially as set forth, to permitthe folding of the finger-beam.

8. The combination in a harvester, of a main frame, a hinged couplin g-frame pivoted to said main frame, a guard-shoe attached to the coupling-frame, and a shoe carrying the inner end of the finger-beam pivoted to the couplingframe, substantially as set forth, to allow thel inner shoe to vibrate independently of the guard-shoe.
