SAMUEL PELTON, OF TRENTON, NEW JERSEY, ASSIGNOR TO FELL, PELTON & BREARLEY.

THRASHER AND SEPARATOR- Specification forming part of Letters Patent No. 44,374. dated September 20,1864.

To all whom it may concern:

Be it known that I, SAMUEL PELTON, of Trenton, in the county of Mercer and State of New Jersey, have invented a new and Improved Thrasher and Separator Combined; and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a plan of my improved machine. Fig. 2 is a side elevation thereof. Fig. 3 is a vertical longitudinal section of the same, the plane of section being indicated by the lineww, Fig. 1. Fig. 4 is a horizontal section in the line y 9 Fig. 2. Fig. 5 is a detached view.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to a machine of peculiar construction, in which the grain is first separated from the hulls, then passed with the straw upon perforated shakers through which the grain falls onto inclined tables or boards, whereby it conducted to a riddle and to the action of a fan-blast so as to be separated from chaff, dust, &c., all as will be hereinafter fully explained.

In order that others skilled in the art to which my invention appertains may be enabled to fully understand and use the same, I will proceed to describe its construction and operation.

In the accompanying drawings, A A A may represent various parts ota frame, upon one end of which is'mounted a hopper, B, feedingtable B, and cylinder (J, the periphery of the latter being studded with projections or teeth 0, which work between corresponding projections, d, on a concave, D, and thereby separate the grain from the bulls in passing between said cylinder and concave. The cylinder 0 has upon the projecting end of its journal a pulley, c, from which may pass a band, c', from the main driving-pulley 0 from which motion is communicated to the cylinder 0 and to all the other operating parts of the machine. From the concave D the grain and straw passes onto a perforated shaker, E, through which a portion of the grain falls,the remainder of the grain, together with the straw,being conveyed to another perforated shaker, E, at the end of which the straw is discharged after the grain has been separated from it by passing through the perforations in the shakers E and E. The shaker E may be inclined reversely to the shaker E, in order that no grain may pass off at the end of the former with the straw. The shakers E E are suspended from the side pieces, A A A by pivoted hangers a a and the said shakers are moved in opposite directions by pitmanrods F F F, which are connected to a double crank-shaft, F, the latter being turned through the medium of a band,f, that passes over a pulley,f, on the end of the shaft F, and over a double pulley, c, on the cylindershaft. Beneath the respective shakers E E are grain-boards G G, from which the grain falls onto an inclined platform H. The grainboard G is suspended from the side pieces A A independently of the shaker E, by means of pivoted hangers a a; but motion is imparted to the grain-board Gr from the shaker E by a connecting-rod, I, Fig. 3, which is made elastic at its ends, in order that it may conform to the different positions which the grainboard assumes with relation to the shaker 1".

Now, when the crank-shaft F is rotated, the shakers E E not only receive a horizontal reciprocatory motion in opposite directions, but the peculiar manner in which they are suspended by the hangers a a adapts them to have a simultaneous vertical movement, and thus when the machine is in operation the shakers act to first expand or draw out the straw, and then crowd the same together in such a way that it will be impossible for any grain to pass off with the straw at the end of the shaker E. This tossing and vibrating of the shakers E E, besides rendering more effectual the separation of the grain from the straw, causes the position of the latter to be such that its weight will be continually counterbalanced on the respective shakers, and hence when the machine is placed upon a wagon or wheels, so that it may be conveyed from place to place, the motion thereof will be equalized and steady. The grain-board G, while moving with the shaker E, is caused by the rod 1 to receive a similar vibratory motion in a horizontal direction; but at the same time the grain-board G has a vertical motion in the opposite direction to that of the shaker, and by this means while the shaker E is tossing the'hay in one direction the grain is thrown in the oppsite direction upon the board G, and it is manifest that the described manner of suspending and connecting the shaker and grain-board would produce this tossing of the hay and grain whether they were inclined or not.

g may represent fingers or pron gs similiar to those ofa rake and which project through slots gfig in the respective siakersE E. The fingers g are secured upon a transverse shaft, 9, and the fingers g on a corresponding shaft, 9 and on their outer ends the shafts g g are formed with cranks g 9 db se cranks g g are connected together by a rod 9 which is pivoted at g to the stationary side piece A of the frame, so that when the shakers E E are in operation the fingers g y will be alternately elevated an d depressed, as represented in Fig. 3. The fingers g g are employed as accessory to the motion of the respective shakers E E to expand and contract the hay in the manner described. Longitudinal racks e a, secured upon the shakers E E, cause the hay to move gradually in the direction of the rear end of the shaker E, where it passes off after the grain has been entirely separated from it.

Themanner of operating the fingers g y will be better understood by reference to Fig. 5. From the platform H the grain passes into a shoe, J, which has a shaking movement communicated to it from the shaker E through the medium of connecting-rods j and pivoted arms j. As the grain passes from the platform 1.1 into the shoe J, it undergoes the acti m of a blast from a fan, K, whereby the greater part of the dust, together with the chaff, 850., are separated from the grain and expelled from the shoe J at the opening j said fan being adapted to revolve in a case, K. The fanshaft extends through the case K, and carries a pulley, k, for the reception of a band, k, from the pulley 0 In the end of the fan-case K is a valve, K, which is mounted on a pivoted rod, k the respective outer ends of which carry weights is k, the

weight 70 being capable of adjustment upon an arm, k

Attached to the rod 7: at the opposite sides 0' the fan-case, are valves 70 k Now, if the volume of air in the case K increases to such an extent that the action of the fan will produce a too powerful blast, then will be overcome the force by which the'valve K is held in its closed condition, and said valve will be thrown open to the position shown in Fig. 3, the red arrows indicating the direction of the current and that in which the fan K is rotated. While the valve K is thus opening to permit the escape of the surplus air, the valves 70 k are gradually elevated, so as to partially close the openings 70 and thereby shut off to the proper extent the current of air which rushes in to the action of the fan. By adjusting the weight k in closer proximity with the shaft k the valve K may be forced open with less pressure from the inside of the case, and vice versa, and it will be seen that in this manner the blast may be increased or diminished in force to any desired extent (according as the grain is heavy or light) without varying the speed of the several operating parts of the machine. vWithin the shoe J is a riddle, J, upon which the grain is received from the platform H. The shaking of the riddle J causes the grain to pass through onto the small sieves J J the chaff and greater part of the dust being expelled at the opening 3' as before explained. Any dust which may pass through the riddle J with the grain is sifted through the small riddles or sieves J J and passes out at the openings J the grain being discharged at J J.

Having thus described my invention, the following is what I claim as new and desire to secure by Letters Patent: 7

1. The combination of two straw-shakers, E E, suspended by hangers a a and moved simultaneously in opposite directions by a double-crank shaft and pitman-rods, substantially as and for the purpose set forth.

2. The combination of the shaker E and grain-board G, having a combined vertical and longitudinal motion, so as to toss the straw one way and the grain the other, sub-- SAMUEL PELTON.
