JNO. BUTTER, OF BUFFALO, NEW YORK.

IMPROVED MOWING-MACHINE.

Specification forming part of LettersjPatent No. 20,479, dated June 8, 1858.

To atl whom it may concern.-

Be it known that I, JOHN BUTTER, of .Buffalo, in the county of Erie and State ot' New York, have invented a new and Improved Mowing-Machine; and I do hereby declare that the followingis a full and exact description thereof, reference being had to the accompanying drawings, and to the letters ot'ret'erence marked thereon.

The nature of my invention relates, first, to an improvement in the construction of the fra-me, so as to give the machine the feature ot iiexibility when mowing and adjustability for reaping; second, in the construction and arrangement ofa wheel to carry the inner end ot' the finger-bar, so that the wheel will tread on a line with the finger-bar and allow the cutter-bar to vibrate through the wheel; third, in so constructing the guard-ngers that they may be connected to thefinger-bar, and support the linger-bar clear from the ground, and allw the cutter-bar to work on the under side of the iinger'bar; fourth, in the mode of supporting and adjusting the drivers seat on the axle of the driving-wheel; t'th, in the mode of supporting and adjusting therakers scat; sixth, in the arrangement of the wheel, divider, and spring to be used on the outer end of the finger-bar.

To enable others skilled in the art to make and use my invention, I will proceed to describe the construction and operation of the same.

Figure I is a perspective. Fig. 1I is a plan of the under side of the guards, cutters, iinger-bar, and carrying-wheels, as arranged together. Fig. III is a section through the plane X Y. Fig. IV is an elevation of a guard-tinger, showing also a transverse section of the cutter-bar and flngenbar. Fig..V is a transverse section of the carrying-wheel. Fig. VI is an elevation of the same.

A B, Fig. I, represent the main supportingtimbers of the frame. The 1inger-bar is attached to these timbers.

O D E are a series of jointed levers, which support the driving-wheel and give flexibility to the machine. O is connected to the timber B by joint at b. E is connected to the shaft Gr by means of a sleeve. broad circular plate or brace, F, projects from the journalcap h y and prevents it from swaying. D is connected to O by means of the shaft d2. E

connects with the shaft of the driving-wheel by means of the sleeve 'r 1', Fig. Ill. This sleeve turns on the shaft, and the drivingwheel turns on this sleeve. D also connects with the shaft of the driving-wheel and turns thereon, and by means of its large circular rim t2 t2, in connection with a similar rim, r2 r2, on E, they-forrn a perfect support for the driving-wheel and prevent it from swaying.

H H represent bars of spring metal, and which, with the cross-pieces it', make the driv ers seat. These bars are connected to the axlc of the driving-wheel, one on each side,aud turn thereon by means ot'a sleeve for each bar. Each sleeve has notches cut in the edge thereof, through which a pin, lr, passes, and also through the axle of the driving-wheel. By means of these notches and pins the drivers seat is made adjustable. The weight ofthe driver is thus brought directly onto the driv ing-wheel, and is equally balanced thereon.

J is the adjustable seat for the raker; K, driving-wheel.

L is the carrying-wheel. This consists of an outside revolving rim, L, and an inside supportingsegment, Z2 I?, Fig. V. The rim L is supported and revolves upon the segment l2, corresponding bevels being made on the rim and segment, as represented at a n, Fig. V. A standard, y, is bolted onto the finger-bar, and supports the segmentand rim. The wheel will have a vertical movement in this standard, as indicated by the slot s. The segment is made in two parts and riveted together. Fig. VI shows more distinctly the openings O', through which the cutter-bar vibrates. This wheel is designed to carry the finger-bar and relieve its drag upon the ground. It is so constructed that it can work on a line with the linger-bar and allow the cutter-bar to vibrate through it. A similar wheel is connected to the outer end ofthe finger-bar.

N represents thc outside shoe or divider.

O represents a spring and cover for the wheel. This is connected to the point ofthe divider, as seen at s t, and to the segment of the wheel, as seen at r t.

M represents an iron linger-bar.

P is the guard-nger. This is cast in two parts. The bottom part hasa broad recess for the reception of the cutter-bar and the escape of all clogging matter, as represented atm, Fig. IV, and an extension backward for the purpose ot' connecting to and supporting the linger-bar, as represented at m2. The upper part is jointed to the under part, as represented at s3. This joint is for the purpose of rendering more easy the tting ofthe guard to the finger-bar. The two parts may be riveted together,instead of the joint, if preferred. The guards have lateral projections, so that when arranged on the finger-bar they will brace each other on the bottom, as represented atp p, Fig. II. The finger-bar rests upon the guards and does not touch the ground.

g represents steady-pins to hold the cutterbar in place 5 W, sleeve towhichethe springbars H are attached; W2, axle of driving- Wheel; Z, pin which passes through the rims of the levers D and E and holds them rigid When the machine is used for reaping; V, Fig. II, cutter-bar; V2, Figs. III and I, cog-rim of drivingWlieeL j The gearing for driving the cutters is arranged in a common and well-known manner. The arrangement of thejointed levers C D E and the support of the driving-Wheel thereon enables the finger-bar and cutters to conform to the uneven surface of the ground Without reference to the tread of the driving-wheel. The arrangement also enables me to raiseand lower the inger-bar and cutters on avertical line and x them at any height, by means ot' the pin Z, for reaping, the outside Wheel, L, being also adjustable. When the machine is used for reaping a platform is attached.

1. The combination and arrangement ot the jointed levers C D E, for the purpose of supporting the driving-Wheel and giving flexibility to the machine, substantially a-s herein set forth.

2. rEhe arrangement of the carrying-wheel L near the heel of the cutter-bar, so that the finger-bar will pass through the wheel and the outterbar or connecting rod also vibrate through the wheel, substantially as herein described.

3. Constructing the guard-lingers so :'that they may be connected to the nger-bar and support it clear from the ground, andV also allow the cutterbar to Work on the under side of the linger-bar, as herein set forth.

4. The sleeve W, when connected With the spring-bars H H, for the purpose of supporting and, adjusting the drivers seat on the axle of the driving-wheel, as herein described.

5. The arrangement and support of the rakers seat on the lever C, as herein set forth.

6. Supporting and carrying the outer end of the finger-bar by means ot' the specific arrangement f the divider N, Wheel L, and spring O, as herein described.A
