IMPR OVElVIENT lN HARVESTING-MACHINES.

Specificationforming part of Letters Patent No. 5,l'74, dated June 26,115+7.

To all whom it may concern:

Be it known that I, JOHN DUNLAP, of Walworth county, Territory of Wisconsin, have invented a new and useful Improvement in H arvestin g-Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference beinghad'to the annexed drawings, making a part of this specification,

in which-'- Z represents the endless cloth for conveying.

the cut heads of grain, &c., into box B.

c are belts for propelling endless cloth d. f

1 are belts for propelling the reels A.

g is an endless cloth for conveying heads of is driven alongside, ifrequired.

'h are the cutters or knives (which will be described hereinafter) for cutting the grain. i are arms for the support of the knives h. j is the lower part of the swinging brushes k.

1, represented in Fig. 3, (in dotted lines in Fig. 2,) is a piece of 'wood placed close to the knives, to which is fastened either leather or bristles, whichever may be found to be the best for the purpose, which forms a brush.

m represents rollers for endless cloth (I to revolve upon..

n is a piece of iron fastened to the lower part ofthefront part of the machine under No. 3,

. Fig. 1, for the purpose of placing a wheel between the two jaws n of different sizes, as may be required.

0 is the wheel.

12 is a flange placed and fastened upon the outside of main driving-wheel G, for the purposle of receiving the belt f thereon to drive ree s.

q is the felly ofthe wheel 0; O, axle of the main wheel.

1' is a shaft, upon one end of which is placed u is a belt for the purpose of propelling the endless cloth g.

'v is a piece of wood projecting from theside of B for end of shaft 1" to rest on.

w is an iron hinge, made in such a manner as represented, for the front part of the machine toswing upon.

w are the spokes of the wheel a.

v2 is a hook, which hooks into -l-', Fig. 1. Staple the other end of the hook or shank; is fastened to an upright piece of wood, t t, which piece of wood serves for the lever a to pass into, where it is fastened by means of a pin at b", as represented.

A represents the reels.

B B are the boxes of the machine. -B"i.n Fig. 2 represents the after box inside, in which the grain, 850., may fall'when required.

' D, Fig. 1, is the tongue by which the whole machine is propelled. The horses are hitched to the after end of the tongueD and pull with their heads toward the machine, which is right before thein. v

No. 1, Fig. 1, represents the frame ofthe- 7 endless cloth g.

No. 2, Fig. 2, represents theswinging brush, which swings upon the shaft of the reels, for the purpose of cleaning and brushing any heads of grain off the knives that migh hang thereto.

E represents the main shafts of, the reels.

No. 3, Figs. 1 and'2, are points to gather the grain in such a manner that the knives of the reels inay cut all heads clea-r.--

The reels are made in two separate parts, as shown in the drawingsin Fig. 2, at A,where it will be'seen that each works entirely independent of the other. The reason I have in constructing the reelsin. two parts is that a knife is very apt to spring when it is so longas to reach from one side of the machine to the other, as theyare now constructed. Therefore, when the knife is not supported it will spring'and allow some grain to remain uncut, and that in a broken state; but in arranging the knives in the manner that I have represented, they being shorter, do not s ring so much, and obviatea difficulty which is of great moment in a machine ofthis description. Figs. '3 and 6 give a view of the brushes and the knife passing between'them.

The steering apparatus.Fig. A5 No. 4 represents thehub of wheel; 5, the tire of wheels; 6, axle-trees, Fig. 5 5 Fig. 4: No. 7, pins passing through axle-tree 6, the other end fastened into piece 9, by which piece 9 the axletrees 6 are turned by wheel 11, as shown in Fig. 5, No. 11. Fig. 4: N0. 10 is a piece to strengthen the frame upon which the movable-framef or piece 9 slides. Fig. 5:.No. 11 represents a wheel over then stationary platform, by means of which the machine is to be steered. No.'12 are iron rods, which move. the piece9 at pleasure. No.13 represents the upright shaft, which supports the wheel No. 11. Fig. 5: No. 14. represents the platform upon which a man or boy may stand to drive the horses and steer the machine.

Tile cutters or knives represented in Fig. 2, marked h. These knives are made in any of the known forms-say about, three inches broad, square on the edges, and about one inch thick, more-or less. as may be desired,

and ot'anylength tosuit the sizeof the mamany knives as six, and even more, if required. The knives also serve to bring .the standing grain in contact with the stationary knife F, Fig. 2, where the heads of grain are finally cut. Havingstated the use 0 rue knives, I will now proceed with the operation of the same.

The reels A, as represented in the annexed drawings, Fig.1 represents the position of the reels. The standing grain is gathered by the rev olving reel-knives and brought against the stationary knife F, Fig. 2, where it is cut. The heads are thus cut from the standing grain without taking more straw than is necessary to obtain the heads. Al'ter'it is cut itis thrown upon the endless cloth (1, which carries it into 'h assing between the two brushes, one being a stationary brush and the other'swinging upon the shaft of the reel, (what'Imean by the swinging brush isthat the swinging brush swings upon the shaft of the reels,) as repre-- sented in Fig. 3, (marked K,) and in' Fig. 1, (marked in dottedlities at 'K,) which is kept in that position by the weight g. This piece marked K and j form an obtuse angle, as re'psented in Fig. 1.

u The front part of the machine is raised or lowered by levers, as represented in Fig. 1, for the purpose of cutting either high or low grain.

the wheels placed underneath the front .partof the machine to regulate the diiferent heights. By'placing diiferent-sized wheels in jaws n, Fig. 1, the front part of themachine forward of the axle-tree of main wheels upon which the whole machine rests) swings-upon a-hi'ng'e.

belt e, at the same time, in. passing under the cog-wheel t, puts 'it in motion, and by \VlllGh" means it. turns the cogwheel S, which in Figs,

1 and 2 turns the shaft r, and finally propels endless cloth g, thus setting all parts of the machine in motion, performing all that is required of the machine. v The steering apparatus by which. the maohine is directed is represented in a top view at Fig. 4 and an end view'at Fig. 5. (By referring-to those figures all of the different parts will be seen.) N 0.12 shows the rods by means of which the piece 9 will'turn the axle-tree .No. 6 by pin 7, this causing the wheels to be turned in any required direction by means of the wheel 11 and rods 12. The axle-trees are made in two separate parts, a s representedin Fig. 4.. The steering apparatus is connected to the machine by the tongue, as represented in. Figs.

1 and 2, marked D. The horses are hitched a near to the steering." apparatus, pushing the machine before them.

What I claim as my inven tion,'and' ,desire tosecnre by Letters Patent, is

The swinging brush, as represented ,in the;
