IMPROVEMENT IN HARVESTERS.

Spccillcation forming part of Letters Patent No. 46,488, dated February 21, 1865; Reissue No'. 3,495, dated June 8, 1869.l A

DIVISION A.

To all whom t may concern:

Be it known that I, FREDERICK NIsI-IWITZ, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Harvesters, of which the following is a full, clear, and exact description. I

My invention relates to that class of harvesters having two driving and supporting wheels, and a finger-beam hinged to the main frame at one end only.

The object of the first part of my invention is to secure a strong connection between the finger-beam and main frame while allowing the former to vibrate freely vertically on its pivot 5 and the improvement consists in a 'lovel method of securing the heel end of the lger-beam to a socket having semicircular 'ections fitting and turning insemicircular `ves in pendents or down-hangers secured ,and extending below the gearing-frame, and secured by a clamping-bolt to prevent lateral deiiection.

The object of the next part of my invention is 'to cause the inner shoe to run horizontally over the ground, irrespective of the vertical vibrations of the finger-beam on its pivot and the improvement consists in a novel method of combining a strong Inetallic shoe, rigidly secured to the coupling-frame, with a ngerbeam secured to a socket vibrating on a pivot behind the shoe. Y

The object of the next part of my invention is to prevent the cutting apparatus from bear- 4 ing too heavily on the ground, and to protect the lower end of the pitman from being clogged by the cut crop, and also to prevent the cutter from dropping out of the iingerbeam' when folded; and the improvement consists in a novel method of combining, with the fingerbeam and its shoe, a supplementary guard-shoe secured to the frame.

The improvement further consists in a novel method of combining a frame vibrating about a gear-center, and a laterally-projectin g cutting apparatus, hinged to said frame at one end only, with a xed shoe in advance of the finger-beam.

The accompanying drawings represent all my improvements as embodied 1n a machme similar in its general outlines to the one shown and described in Letters Patent of the United States No. 19,377, granted to Ine on the 16th day of February, 1858.

Figure l represents a plan or top view of my improved machine, and Fig. 2 represents a vertical longitudinal section through the machine at the line :c fr of Fig. l, looking toward the divider side of the machine. Fig. 3 represents a view, in elevation, of the rear pendent detached, as seen from the front. Fig. 4 represents a vertical transverse section through the machine at the'line z z of Fig. 1, looking toward the rear, and showing more particu-A larly the method of lifting the divider end oi' the finger-beam.

III this instance two driving-wheels, A A', are shown as mounted loosely on. a common axle, B, with which they are connected by backing-ratchets of well-known construction. The axle B revolves loosely in suitable bearings on the gearing-frame C. An internallygeared spur-wheel, D, is secured upon a concave disk, d, fixed upon the gearing-frame in such manner that the spur-wheel D is concentric with the axle B. An arm, E, fixed upon, revolving with, and projecting on each side of the axle B, carries spur-pinions E', revolving freely on pins e, and meshing on one sideinto the spur-wheel l), and on the other into a spurpinion, F, fixed on a collar, f, turning freely on the .main axle, and connected by a feather, f', with a collar, g, also revolving loosely on the axle B, and carrying a bevel-wheel, G, driving a corresponding pinion, h, on a crankshaft, H, which drives the cutters I by a crank and pitman, h', in the usual way.

The mechanism is thrown into and out ol gear by means of a shipping-lever, G', provided With a cam-yoke iittin g over a flange on the collar A tongue, J, is hinged to the main frame by a pivot, j, so as to vibrate freely vertically. A loop, 7c, on the front of the gearing-frame encompasses the tongue, acts as a stop to limit its descent below a given point, and sustains it against lateral strains, as in turning.

A lifting-lever, L, is pivoted on the tongue,

and is connected with the forward end of the l over a pulley on the tongue. A pawl, L', pivoted on the hand-lever, takes into a vratchetplate on the tongue, and holds up the gearingframe, as described in my patent of 1858, hereinbcfore referred to.

A seat, M, for the driver is mounted on an inclined arm, M', pivoted at m to lugs on the draft-frame. This arm M is supported at a point intermediately between the pivot and the drivers seat by a link, m', pivoted both to the bar and to the gear-frame behind the main aXle, as shown by the dotted lines in Figs. l and 2. The pivots of the tongue, the inclined arm, and of the connecting-link thus form a sort of parallel rule-joint, Which compensatcs for the vibrations of the tongue and gearing-frame, and enables the driver to maintain his proper relation to the lifting-lever, in stead of his seat rocking backward and forward, as it Would do if mounted directly upon the gearing-frame. As the seat is located behind the main axle, the Weight of the driver tends both to lift the tongue and to depress the rear end of the gearing-frame, thus diminishing the pressure of the cutting apparatus on the ground, and causing the machine t-Q run more lightly. The link m is connected both with the arm M and with the frame by slots and set-screws, which permit it to be adjusted backward or forward, and thus balance the machine.

The finger-beam N is securely fastened to a socket, Nf, provided with scmicircular projections or an ges n, fitting in semicircu'lar grooves o in pendants 0 0', rigidly secured to the ner front corner of' the gearing-frame, and connected by a clamping-bolt, o'. A metallic .shoe, P, is firmly secured to and projects in advance of the front pendant 0. rEhe {ingerbeain is thus free to vibrate vertically on its pivots, while the shoe P is fixed. The lingerbeam may likewise be readily detached from the main frame.

A supplementary guard-shoe, Q, composed of a fiat bar of metal, is secured at its front end to the main frame, and curved downward, and its rear end is secured to its rear' pendant O.. As this shoe is slightly elastic it relieves the pressure of the cutting apparatus upon the ground, and protects the pitman from being clogged by the cut crop; also prevents the cutters from falling out of the guards when the finger-beam is folded up.

A lever, It, is pivoted to vibrate vertically on a pivot, r, on the g'earframe. This lever is arranged in the same vertical plane as the finger-beam, is interposed between the tongue and the gearing-frame, and its outer end is connected by a chain, 4", With the finger-beam, at a point outside of its hinge. Consequently when the gearing-frame is lifted, by means of the hand-lever L, the tongue depresses the Wider than the distance between the drivingy Wheels. p

The operation of this machine being similar to other machines of this class, it is deemed unnecessary to describe it here.

What I claim as my invention is-- l, Connecting the finger-beam with the main :frame by means of a joint composed of semicircular grooves in the pendants, and semicircular projections on the socket of the fingerbeam, substantially as described.

2. The combination ofthe rigid metallic shoe with the finger-beam vibrating on a 'pivot l* hind the shoe, substantially as set forth 3. The combination of the main frame, finger-beam, and the pitman with the suppl, mentary guard-shoe, operating substantially as set forth. p

,4. The combination of a frame vibrating about a gear-center and a laterally-projecting cutting apparatus hinged toA said frame at one end only with a xed shoe in advance of the l finger-beam, substantially as set forth.
