to nijnen snriooe of one inf Q tothe ends of4 the lingers, and they fastened to itvthroughout their length, but no simultaneous vibrating motions are given by means of two connectiugrods,'k, attached4 to a double crank, k', on a shaftlocated beneath the rear section, C, which `shaft carries Ia pin ion, l, gearing with the large toothed wheel F on the main shaft G, which inay be driven by a belt or in any other convenient way. The

other ends ot' the two connecting-rods are attached to the rear ends of the two sectionsA of the separator, asshown in Fig. 2. The sections C andfE are suspended by means ofradias-bars m m', and they thus have a vertical oscillatory motion, aswell as a back and forth motion. By thel opposite and simultaneous motion of the sections of the separator the` momentum and inertia of one part will be counteracted by that of the other, and thus there will not. be so great a tendency to jarring and unsteadiness in the frame when tlfe machine is infoperation. Other important results are also thereby attained, which will be hereinaftermentioned. The mixed mass of straw, grain, 85e., is thrown from beneath the thrashing-cylinder up the inclined plate D, through the openings,h,in which much of the `grain passes, and diverging ridges onwhich constantly tend to spreadout the mass later- Alally as itis delivered to the elevated fingers j. The portion of the gra-in which remains with the mass of straw, &c.,is delivered upon thenl '4 gers j, and more of the grain is here separated from the straw and falls upon the bottom d between the lingers. lThese lingers are so arranged with respect to thebottom ofthe separator as to carry oil' the hull; of the straw, while the bulk of the grain is carried by the bottom d. They are elevated above the bottom,being attached,y by their rear ends to a diaphragm or false bottom, d', which forms apart of and vibratcs with the rear section of the separator, and carries the fingers with it in its vibrations.

. A space; {',is thus leftl beneath the diaphragm dand fingers j, through which the grain is carried forward and over the head or shaft a `of the fingers owithout obstructing its action. These fingers have thus to lift vup only the bulk et straw, 85e., which is/del-ivered upon them ``from the lingers j, and their labor is 'therefre much less than if the whole mass of mixed straw, grain, &c., were delivered to them before this partial separation. The diaphragm vor false bottom cl,to which the elevated tin gers j are attached, may be extended forward may. be

advantage` is gained by so 'constructing it.

The' vibrating `lifting-fingers o are attached -to a rod or shaft', a, and are caused to rise on theforwardswing of the rear section ofthe separator and lift and shake the straw, at the same time facilitating its progress through the separator and the separation of the grain from it, and then with the back swing ofthe section they resume their position upon the bottom of the separator, the motions ofthe fingers bein g regulated by and uniformwith those ci" the rear section ofthe separator, though they only grain, and chad' lying across their overlapping l ends'is drawn vout and attenuated inthe following manner: As section C ofthe separator advances the fingers rise and lift the straw, at the same time urging it forward and throwing a portion of the mass upon the front section, E, and when the motion of the section is reversed, and the rear section, C, recedes, the front one, E, at the same time advances and the mass of straw, Src., upon the front section, E, moving forward with it, is drawn away from that upon the rearsection, C, because it tends to move back with said section, and thus the mass is drawn out and attenuated whenever the front-and rear sections of the separator move toward their respective ends of the machine,- and the grain is thus allowed to drop more readily from the straw., by its weight and fall into the winnower, as hereinafter dethe machine, or is arranged in any convenient.

way so as not to be permitted to follow the motion of the separator as it vibrates back and forth, while it is free to move up and down,` allowing -the lower end of the `lever and the shaft of the lingers o to move back and forth with the separator. By such means the shaft a will be caused to oscillate, raising and lowering the fingers uniformly with the forward and back motions of the rear section of the separator. The grain, &c., carried by the bottom d of the rear section, C, of the separator is delivered directly upon the front section, E, while ythe straw and coarse staf-.end egrain sive series of vibrating liftingingers, q and r,

which are arranged 'in the frontsection, 13h-ot'4 the separator, and are operated by means of rods or levers q' and r', in like manner with those attached to section G, already described, and which, in like manner, rise upon the for# ward swing of the section E, and resume their 4horizontal position as the section swings back; `These Afingers give the straw. a still further shaking, and eectually'separate thefgrairr from the strawbefore the latter is throivi'rdnt
