DIvIsIoN D.

To all whom it may concern:

Be it known that I, LEWIS MILLER, of Ganton, in the county of Stark and State of Ohio,

have invented certain new and useful Improvements in Machines for Harvesting Grain and Grass,ofwhich the following isa full, clear, and exact description, reference being had to the accompanying drawings, which make part of this specification, and in which- Figure 1 represents a view in perspective of the machine as arranged for mowing. Fig.

by means of a hand-lever to pass over au obstacle. Fig. represents by the black lines a front elevation ofthe machine with the ngerbeam folded over upon the frame in a compact manner. The red lines show the ngcrbeam raised onend preparatory to being lifted by the hand-lever and turnedoverupon the frame, and the blue lines show the finger-beam almost raised up and turned over upon the frame. Fig. 4 represents a view of the under side of the main frame and certain parts connected therewith, but showing more particularly the arrangement of the brace for supporting the coupling-arm. Fig. 5 represents on an enlarged scale a'view of one side of a portion of the connecting-rod which transmits inotion from the crank to the cutter. Fig. (i represents a front view ofthe quadrant-lever for lifting and the ratchet-teeth and detent for holding up the linger-beam when raised; also, a fragment of the adjacent part of the frame detached from the machine. Fig. 7 represents a similar view of the same parts, the

quadrantlever and its ratchet-teeth being in the position they occupy when turned asideto disengage the teeth from the detent preparatory to raising lor lowering the nger-beain. Fig. 8 represents a view of the side of the quadranthaving the ratchet-teeth thereon;

and Fig. 9 represents a vertical section at the line a: :v of Fig. 1, showing the knuckle of the jointconnecting the finger-beam and couplingarm.

That side of the machine on which the iinger-beam projects when on the ground in the position sho-wn itlY Fig. l l call the side. The other I call the left side.

ln a mowing-machine having a finger-beam which is connected to the main frame by a hinged coupling-arm, so as to admit of thelnger-beam being raised from the ground and folded over upon the frame to render the machine morecompact and convenient for transportation, it is diicult, by manual force alone, and even somewhat dangerous, by reason of the great weight of the linger-beam and ofthe sharpness of the guard-fingers and the cutter,

to raise and fold them up on the frame, and it requires two persons-to do it.

To enable one person to raise and fold up the linger-beam conveniently and without danger' is the object of thc invention claimed under this patent, which consists in combining with the folding linger-beam a lifting-lever and con nectin g-cord, or the equivalent thereof, to aid in raising the iinger-beam and folding it upon the frame.

The accompanying drawings represent a vmowingmachine having its main frame A A A2 A A4 A5, supported by an axle, C, and a pair ofv wheels, B and B', and having a tongue, Y, for the horses to draw it by, which projects from the front of the frame.

The ijngerbeam is hinged at its left end to the right end of a coupling-arm whose left end is hinged to a bracket or hanger, H, on the under side of the main frame.

On the side of the-rail AZ of the frame a quadrant, Q, is supported on a pivot, g, and litted with a hand-lever, R, for the purpose ot' turning the quadrant up and down to raise and lower theflnger-beam. Y The front edge of the quadrant is grooved to receive and guide a cord or strap, u, fastened by one end to the upper corner ofthe quadrant and by its other end to the couplingarm, near its right end. When they lever R is depressed the quadrant is raised and lifts the coupling-arm; and if', be-

fore lifting the coupling-arm, the finger-beam" be turned upon, end against the side of the frame, as shown by redlines in Fig. 3,then, when the lever is depressed and the quadrant ill-ight,"

raised, (lifting with it the end of the couplingarm suspended by the cord,) the linger-beam will be raised bodily upward and, leaning against the frame, its own weight will carry it down to the left, so that it will gradually'assume the position shown by the blue lines in Fig. 3, and finally will reach the position shown by the black lines in that figure, lying compactly, bottom upward, upon the frame.' Theraising of the hoger-beam and folding it over upon the frame in this manner are effected with great ease by a person of ordinary skill and moderate strength. To unfold the fingerbeani and again lay it upon the ground is likewise effected with great ease by simply raising up the end which lies upon theleft side of the frame and. allowing its right end to slide over the right side of the frame, as it tends to do, and to descend by its own weightto the ground, when the parts will again occupy the position shown bypred lilies in Fig. 3, and by simply l turning the upper end over to the right the finger-beam will tend to'descend by its own weight, andneed only be lowered to the ground with moderate care to avoid the risk of injury that would attend a -fall with its full weightL and momentum upon somehard substance-as, for example, a stone. When lowered to the ground the ringer-beam will occupy the position shown in Figs. 1 and 2.

Vhat I claim under this patent as my invention is- The methodof folding the finger-beam upon the frame by the aid of the coupling-arm with a liftingdever and cord, or the equivalent thereof, substantially as herein set forth. l

In testimony whereof I have hereunto subscribed my naine.
