BYRON DENSMORE, OF SWEDEN, ASS-IGNOR TO D. M. OSBORNE, OF AUBURN, AND W. A. KIRBY, OF BUFFALO, NEW YORK. v

IMPROVEMENT IN HARVESTERS.

lSpecification forming part of Letters Patent No. 8,720, datedFebruary 10, 1852; Reissue No. 1,262, dated v January 28, 1862.

To all whom it 'may concern:

Be it known that BYRON DIJNsMoRE, ofthe town of Sweden, in the county of Monroe and `State of New York, assignor to DAVID M. Os# BORNE, of the l'city of Auburn, and WILLIAM A.KIRBY, of the city of Buffalo, and St-ateaforsaid, heretofore invented certain new and useful Improvements in Harvesting-Machines. Now, therefore, we, the said DAVID M. OS- BonNE and WILLIAM' A. KIRBY, assignees of the whole interest of the said BYRON DENS- MORE, as aforesaid, do hereby declare that the following is a full,clear, and exact descripi tion of the construction and operation of the said invention and improvements, reference being had to the accompanying drawings, making a part of this specification, in which- Figure I is a perspective view of the machine. Fig. II is a vertical longitudinal section on line x y of Fig. III. Fig.III is a top plan ofthe machine. Fig. IVis avertical longitudinal section through the driving-wheel, showing the combination of the main and supplemental frames. Fig. V is a view of the outer,

` the driving-wheel and the other for supporting the cutting apparatus-and hinging thc said frames together in such manner that the driving-wheel and cutting apparatus may each follow the inequalities of the ground independently 'of the other,'and also that they may be bolted rigidly together for supporting the cutting apparatus at any desired height; second, in providing a ground-wheel with crank and lever for raising and lowering the outer end of the finger-bar.

Letters ot' like name and kind refer to like parts in each of the figures.

A represents the main frame of the machine, which consists of several pieces of timber properly framed and bolted together. This frame carries the iinger-bar and cutting apparatus,1as herein described.

B are two upright posts forming part of the main frame for the purpose of supporting the drivers seat and for forming an adjustable connection with the supplemental or wheel frame.

C represents a supplemental frame, in which the driving-wheel ishung, Itis hinged to the main frame by means of bolt and hinge-plate, as shown at d, so` as to allow it to have a hinge or joint-like movement, the object being to have a hinge orjoint-like connection between the two-frames, so as to allow an independent movementof each frame. The particular manner of forming the hinge orjoint connection is not deemed important. Any mechanical means by which the end is secured will answerthe principle of the invention.

in' close proximity to the upright posts B, so that it may be made fast to said posts by means of bolts passing through said posts and frame at either of the several bolt-holes b', by which means an adjustability is secured, and the cnttin g apparatus thereby raised and lowered and supported at any desired height from the ground when reaping.

When desired the adjustingbolts may be removed entirely, and this end of the frame left free to oscillate or swing from its hinges, according to the uneyenness ofthe ground over which the driving-wheel passes may require. By this combination and connection of the two framesit is evidentthat the driving-wheel, when mowing, may pass over uneven surfaces without causing an elevation or depression of the finger-bar andl cutting apparatus, and the finger-bar and cutting apparatus may also conform to the inequalities of the ground independently of the position of the drivingwheel, and a uniform flexibility between the two frames constantly maintained, the elevation or depression of the driving-wheel and the elevation ordepression of the cutting apparatus (occasioned by the uneven surfaces of the ground over which the machine passes) not he ing simultaneous nor dependent one upon the other. The axle of the driving-wheel has api The opposite end -of the frame moves in the arc of a circle, and

propriate bearings upon the side pieces of the supplemental frame, as shown at c', Fig. III.

lhe gear-wheels for communicating motion f to the cutters are shown at l 2 3v 4, each hun g in a common manner upon its appropriate shaft, as shown in Fig. III.

The ground-wheel F (shown in Figs. I, III, and IX) is on hung the crank h, which crank is supported by boxes on each side of the wheel, made fast to the frame. G; or it may be supported ou the ing'er-bar'or divider in any convenient' manner, so that the wheel maybe made to adjust and carry theouter end of the finger-bar, as desired. One object of hanging this wheel on'a crank-shaft with a lever attachment thereto is to provide a meansfor conveniently raising and carrying' the outer end of the cuttngapparatns free from the ground when it is desirable `to move the ma. chille from place to place. Another object is to'aiord a means for raising, lowering, and

' supporting the outer end of the finger-bar and cutting apparatus at different heights from the ground when the machine is used for reaping.

The essential feature of this part of the inven-v tion is hanging the wheel upon a crank-shaft with the crank-and lever for operating the same,` so that the purpose of raising and lower- 'ing the outer end of the finger-bar is attained.

The precise details of the arrangement are not deemed important..

The finger-bar H is made fast to' the side pieces of the main frame upon the upper side of the said pieces by bolts or otherwise,as shown at a', so that the inner side piece vwill serve as an extension-shoe or runner to slide over the stubble or mown grass, and protect the heel of the cutters.

D n s the driving-wheel; Z, draft pole attaohed to the main frame, and to which the team is harnessed in the common manner.

Having thus fully described the construction and operation of the said improvement, whatwe claim as the invention of the said BYRON DENSMORE, is- 1 l-.Hangingthedriving-wheelinasupplementary frame or its equivalent, which' is hinged at oneend to the main frame,while lts opposite end may be adjusted and securedat various heights or be left free, as desired, whereby the cutting apparatus may be held atv any desired height for reaping, or be left free to accommodate itself to the undulations ot the ground for mowing, substantially as described. 2. The employment in, a harvesting-machine,

o fa wheel provided with a crank and lever for the purpose of raising and lowering the outer end of the ngenbar to cut high or low, substantially as described.
