the accompanying drawings, which makepart of this specification, and in which- Figure l represents a view in perspective ot" the machine as arranged for mowing. Fig. 2 represents a front elevation ot' the machine, the black lines showing the [loger-beam resting upon the ground in the position it will occupy when the machine is mowing on a level surface, the red lines showing the position of the finger-beam when mowing onl an uneven surface, with its left end raised to conform thereto, and the bluelines showing the fingerbeam raised ott' and held parallel-to the ground by means of a hand-lever to pass over an obstaclc. Fig. 3- represents by the black lines a front elevation of the machine, with the fingerbcam folded over upon the frame in a compact manner. The red lines show the linger-beam raised on end preparatory to being lifted by the hand-lever and turned over upon the frame, and the blue lines show the finger-beam almost raised up and turned over upon the frame. Fig. 4 represents aview ot' the under side of the main frame and certain parts connected th/erewith, but showing more particularly the arrangement ot' the brace for supporting the Acoupling arm.

Fig. 5 represents on an enlarged scale a View of one side of a portion of the connecting-rod which transmits motion from the crank to the cutter. Fig. 6 represents ar front View of the quadrant-lever for lifting, and the ratchet teeth and detent for holding up, the linger-beam when raised; also f a fragment of the adjacent part ot' the frame detached from the machine. Fig. 7 represents a similar view ofthe same parts, the quadrant-lever and its ratchet-teeth being in the position they occupy when turned aside to disengage the teeth from the detent preparatory to raising or lowering the finger-beam, and Fig. 8 represents a view of the side of the quadrant having the ratchet-teeth thereon.

Fig. 9 represents a vertical section at the line m .fr of Fig. 1, showing theknnckle of the joint connecting the finger-beam and couplingarm.

That side of the machine on which the tingcr-beamprojects when ou the ground, in the position shown in Fig.' 1, I call the right side; the other I callI the left77 side.

Gomparatively few farmers raise their crop of grass for hay ou a single large meadow, as

grass thrives best in moist ground not well ,adapted to raising grain, and such ground is usually in Ismall patches in the low places scattered over the farm. Hence in mowing his crop the farmer usually yfinds it necessary to draw his machine through numerous narrow lanes and rough by-paths in taking it to the various grass-patches to be mowed. A machine of the ordinary construction with the finger-beam projecting at one side can scarcely be conveyed along such paths, except when placed upon a wagon or sled and carried with the linger-beam end foremost. transportation involves so much labor and inconvenience in loading and unloading that various contrivanees have been made to'avoid it, the most efcient of which contrivanees, so aras my knowledge extends, is one heretoore patented by Aultman and Miller and which consists in turning theiinger-beani into an upright position against the frame, which renders the machine quite as narrow as an ordinary Wagon; 'but this leaves -it top-heavy, and also with a great preponderance of weight on one side, so that when the machine is much lower on the side on which the finger-beam is 4hung than on the other side it is very liable to overturn. g

To remedy these defects by rendering the machine more stable and more compact, and therefore vmore portable, is the object of the invention which is claimed under this patent, and which consists in so constructing and ar ranging the machine that the linger-beam, together with the cutting apparatus, can be lifted up and folded over upon the main frame, where it lies compactly and securely, thus rendering the machine capable ot' being moved about on rough and narrow roads as safely and conveniently as acommon cart.

In the accompanying drawings, the main frame A A A2 A3 A4 A5 of the machine is sup- 'lhis mode of ported by au axle, C, and a pair of wheels, B and B. A tongue, Y, projects from the front of the frame for the horses to draw the machine by.

Ihe ingerbeam M, which supports the guard-fingers a, and the cutter K are connected by a coupling-arm, L, to the main frame, the

` arm being hinged at one end to the fingerbeam and at the other toa bracket, H, on the under side of the main frame, which bracket projects downward about half-way from the under side of the frame to the ground.

The coupling-arm is connected by a cord, n, or the equivalent thereof, to a quadrant, Q, which is secured by a pivot, g, to the beam A2 of the frame and turned by a lever, R, for the purpose of raising and lowering the couplingarm and ngerbeam suspended to the quadrant by the cord.

The finger-bean] is folded over upon the frame by iirst raising its rightv end and turning it up against the frame into the position shown by the red lines in Fig. 3. Then the right end ofthe couplinglarm, with the lingerbeam pressing upon it,is raised, the Ingerbeam turning by its own weight toward the left side of the frame, as shown by the blue lines in Fig. 3, and they raising of the coupling-arm and the turning downward of the nger-beam toward the leftare continued until the linger-beam is laid bottom upward upon the frame, as shown by the black lines in Fig. 3,'Wheu the machine is reduced into such a compact and secure shape that it may be taken safely wherever' an ordinary Wheeled vehicle can safely be drawn by a team.

The other portions of the machine, which do not relate to the subject-matter Yof the claim under this patent, I do not deem it necessary to describe more particularly here.

What I claim under this patent as my intion is Hinging the finger-beam to the main frame, so that it can be folded up thereon, substan tially as herein described.

In testimony whereof I have hereunto subscribed my name.

LEWIS MILLER.
