The letters represent-the different parts of saidmachine.

ll M N is the main suppor-ting-fran1e,which is constructed in the comnion way. A is the main drivingavheel K the shaft, and F F the arms of sarne. .ifi'is'a cam. attached-to the inner periphery of the drivingwheel. (.l is a .(l'OSS-lltflli. is a pitnian. (t is a key. Eis

a stirrup. (l G are s rings. H is a hub or fulcrum. J J" are bolts and nuts. I 1" are cams upon the underside of the cross-head (J, as in Figs. 4 and 5. P is a nut. q is awasher. R is a bolt. 8 is a recess in the edge of the pitman I). 0 is a hole infi'the end of the said pit-man, where thesickle-bar is attached.

Having named theseveral parts of the said machine, I. will now explain its operation and construction as best I can.

The frame flli M N of the said machine is made in the usual way, thedriving-wheelA also, with the exception that the arms F F thereof are attached to the side of the rim. 'Upon the inner periphery of the said wheel I place azigzag way or cam, B, sometimes whole and at other times in sections. I pre- .l'er the sections, for the reason that it is more veasily repaired. In front of the said wheel and lnatween the cross-beams L L, I place the stirrup 1*}, and fasten it to the said beams with the bolts and nuts j j; and itis obvious that the said stirrup can easily be tilted toward the rear of the said machine, or toward the front, as may he rm uired, which will be more fully explained hereinafter. New, this said stirrup is peculiarly (oust nueted with a base and sides or cars. .At right angles with. the sanic, upon the upper surface of the said'base, isa hub or PATENT. OFFICE. a

-':- Specification thrming partot' Letters Patent No. 35,923,' dated July 22, 1862.

flll(..llllll,ll,lfllld the pitnian D hangs upon this said hub, the hole through the said pitinan corresponding in sizewith the said-hub, and the height of the said. hub corresponds also with the thickness of the said pitinan. Now, I insert a bolt, B, through the center of the said hub from the bottom of the said stirrup. Now, when the said pitinan is in its proper place, as described, and as seen in Fig; 6, It place a washer, q, upon the top of tl-e said hub, (the'said bolt passing through the center of it also,) and then I put the nut p upon the said bolt and screw it down upon the top-of the said washer, which said washer lies upon the top of the said huh, and in this avay permanently secure the said pitman in its place; but it will be understood that the said pitman is sul'iiciently relieved to admit of free action.

It will be seen in Fig. 2 that the fulcrum of the said pit-man is immediately in front of the said driving-wheel; hence the necessity of crooking the rear end to pass by the side of the said whee]. Upon the rear end of this said pitman I place the cross-head C, and fasten it there with the key a, as seen in Fig.

8, a mortise being in the end of the saidcrosshead, corresponding in size with the size of the end of the said pitn -an. On the inner edge of the said pitman is a recess or boxing, 8, into which the said cross-head is placed, and is permanently held there when the said key is inserted into its proper place, as seen in Fi g. 3. The said cross-head is constructed with cams I l. on the under side thereof, as seen in Figs. 4 and 5, corresponding with the angle of the said-cam upon the inner periplr cry of the driving-wheel. It is manifest, therefore, that when the said cross-head 'is properly adjusted to the said cam on the said wheel and the said wheel set in motion the said cross-head, and consequently said pit-man,

will Vibrate equally with the angles or radius ot' the said cam. The said pitman being pivoted at ornear the middle thereof it is also manifest that the other or front end thereof will also vibrate in the same proportion with the rear end. The sickle or cutting apparatus, bei ng attached to the frontend of the said pitman at the point 0, as seen in Fig. 3, is also set in motion when the machine moves.

The springs G- G" are attached to the sides or ears of the said stirrup E, and extend forward in the plane of the said pitman, .sufiicie'ntly inclined toward the same to bring them in contact with the sides thereof at or near the end. The use of the said springs is to soften the action ofthe said cross-head upon the said cam and to regulate the motion of the entire machine The object of hinging. the said stirrup upon the said bolts j j (as before stated,) is to enable meto throw the machine in and out of gear, for it is clearly manifest that when I tilt it. toward the front the rear end of the said pitman will raise and-consequently detach the saidcross-head from the said cam of the said whee] and therefore stop, the'motion of the said cutting apparatus; and when I reverse the position of the said stirrup by tilting it toward the rear of the said machine it brings the said crosshead in contact with the said cam again, and thereby sets the cutting again in motion, and vice Versa.

What Icl-aim, and desire to secure by Letters Patent, .is

1. The adjustable hinged stirrup E, in com- I bination with the pitman D, when constructed and arranged in relation to each other as specified, and for the purposes described.

2. The springs G G in combination with the said stirrup E and the pitman D, when the several parts are constructed, arranged, and operate in the manner and for the purposes speified.

3. The cross-head O, in combination with the said pitman and the main driving-wheel A,when the several parts are constructed, arranged, and operate in the manner and for the purposes specified.
