To all z'uhom it may concern.-

Be it known that I, GARDNER'AJ GIBBS, a citizen of the United States, and a resident of Livonia, in the county of Livingston and State of New York, have invented certain new and useful Improvements in Separators, of which the following if a specification.

My invention relates to that class of machines used for sorting beans, peas, and various grains and separating fromihe'm foreign substances, and has for its object to provide means for quickly and accuratelyaccomplishing this separation.

In the accompanying drawings, Figure 1 is a side elevation of the machine; Fig. 2, a top view; Fig. 3, a section on'the line 3 3 of Fig. 2; Fig. 4, a section on the line 4 4 of Fig. 2, and Figs. 5 and 6 parts hereinafter to be described.-

In the drawings is shown a machine illustrating my invention, in which A represents the main stationary frame of the machine, on which are supported the various parts. Within this main frame and pivoted to its end bars A A by bolts 1) b, so as to be capable of transverse tilting, is a second frame composed of end pieces B B and side pieces B B A block b is shown (see Fig. 1) between the end piece B of said tilting frame and the cross-piece A through which also the bolt 1) passes. .The bolt 1) lies within a slot 19 in the" cross-piece A of the stationary frame, (see Fig. 4,) so that this end of the tilting frame may be raised or lowered through the length of this slot. The frame may be secured at the height desired by the nut 6 which is shown with a handle attached to it, by which it is operated. A handle-bar b is attached to the other end of the tilting frame and the bolt 19 passed through it and the cross-piece b Said handle-bar projects outward beyond the stationary frame in the manner shown in Fig. 1, affording means for tilting the frame. It may be secured in place by a nut b upon the bolt 6 which latter lies in a slot in the post A, which permits the adjustment. The slot is not shown in the drawings.

It is desirable that the frame B should be capable of both longitudinal and transverse tilting in order that it may be adapted to the separation and grading of different objects,

some of which roll much more readily than others.

Secured uponshafts c c, which are transversely journaled in the side pieces 18 B of the tilting frame near its ends, respectively, are rollers C 0; Attached to the end of the shaft 0 and extended beyond the stationary frame a crank c is shown, with handle 0 by means of which the roller 0 may be revolved. The device can of course as well be driven by any other power, and suitable attachments therefor can be readily made for it. Between the rollers C O and supported by the side piece B of the tilting frame is a table D (see Figs. 3 and 4) for the support of the endless belt E, which is passed around the said rollers and over said table. The upper surface of this endless belt constitutes a movable carrier on which the objects are separated in the manner hereinafter to be described and from whose surface they are conducted when separation has taken place into distinct masses. Between the edge of this table and the side piece 13 of the tilting frame a space 19* is left, as shown in Fig. 4.

Chutes E E are attached to the tilting frame in the position shown in Figs. 1 and 4. The upper edges of the inner faces of the said chutes are placed somewhat below the upper side of the belt, (seeFig. 4,) and their outer surfaces are carried up above the lower edge of the side piece B of the tilting frame, as is shown in Figs. 1 and 4. Extending along the bottom of the table D and resting on the top of the inner surfaces of the chutes E E is the inclined surface or platform F. (See Figs. 3 and 4.) A partition G (see Figs. 2 and 3) is placed across said platform. F at a point between the chutes E E. Attached to the end of the tilting frame beneath the roller 0 is a third chute H, and above the belt and supported on the main frame A is a hopper K, provided with a gate or slide it, as indicated in Fig. 1, wherebybeans are dropped in regulated quantity upon the belt.

The functions of the several parts will be clearly shown in the description of the operation of the machine found hereinbelow. v

In my machine the separation is accomplished by spreading out or dispersing the beans upon the belt during their passage on IOO it, thus permitting the round most perfect beans to separate themselves from the mass and to roll off from the belt into receptacles placed to receive them, while the imperfect beans and refuse matter remain upon the belt and are carried to another chute through which they are discharged. By the device I employ the beans are repeatedly thus spread out and dispersed while on the belt, and the separation is thereby rendered very complete and thorough. To accomplish this, I place back and forth across the-belt in Zigzag order, alternately, beginning on the left beneath the hopper K, guides L and M. (See Figs. 5 and 6.) One end of each guide M lies within grooves in the side piece B, and the other end is set in aslotted block m, whereby the guides are retained in position. One end of the guides M also fits within notches Z in the guides L, and the guides L in turn are slipped within one of the notches m shown in the guides M. In this way the guides are fixed in place, the several notches shown in the guide M for the reception of the end of the guide L making it possible to change the angle of the guide L with reference to the line of movement of the belt. The lower ends of both guides are set close to the belt E; but the manner in which they are cut away (shown in Figs. 5 and 6) leaves passages through them near the upper and lower edges of the belt alternately, as shown by the arrows in Fig. 2.

The operation of this machine is as follows: When the tilting frame has been set at the proper inclination and its lower end adjusted to the height desired, the belt is put in motion and the beans are allowed to fall from the hopper K upon the belt. They are carried on it along the first guide M until they reach the passage shown by the arrows in Fig. 1, through which they pass. As they come out from the passage into the space N, between said guide M and the next guide L, they are dispersed across the belt. The round most perfect beans will then roll down the inclined surface of the belt and falling upon the guide-surface F beneath will be directed into the chute E The remaining beans and the foreign substances mixed in with them will be carried forward by the belt and collected against the guide L, along which they will move to the next passageindicated by the arrow. The beans will be carried along said guide L in a thin line from which the round ones will soon easily separate themselves to roll down the belt. Entering the space N theyare carried up along the guide M to the top of the belt again, to be once more scattered across the belt, so that the round beans may roll off into the chute E. The beans are thus carried successively to the spaces N, N N ,N*, N N, and N. In the spaces N, N N and N they are spread across the belt, so that the round ones may roll down the inclined surface of .which remain upon the belt.

the belt, while on each of the spaces N, N N and N they are carried back to the top of the belt, and the separation is facilitated during their passage along each of the succeeding guides L L and L. The arrows in these spaces indicate the course of the beans. That of the round beans is indicated by the lower arrow in the spaces where two arrows are shown, while the upper one indicates the passage of the beans and foreign substances It will be noticed that each successive guide of the pattern L, beginning on the left with the guide L is set at an angle with the next forward adjacent guide of the pattern M which is more acute than was the last. This adjust.- ment is accomplished by placing each successive guide L L &c., in a lower notch m in the adjacent guide of the pattern M than was the last. In this way the path of the beans across the spaces N N N N is turned more directly across the belt in each successive space as the beans progress, thus increasing the tendency to roll them from it. The partition G, hereinbefore described, divides that port-ion of the inclined surface from which the beans are carried to the chute E from that portion from which they are carried to the chute E. Inasmuch as the most perfect beans will be the first to roll from the belt they will be carried to the chute E, while an inferior grade, which will not roll from the belt until they encounter those guides which are set at great er inclination,are turned into the chute E. Thus the beans are sorted into two grades, and refuse matter and those beans (split and rough) which are below grade are carried off on the belt to the chute H, through which they are discharged. The hopper E and the portion of the inclined surface F which feeds it are longer in the drawings than the hopper E and that portion of the inclined surface over it. This proportion of these parts is recommended for the reason that all the beans of the first quality are not as likely to be drawn off from the mass of beans when first spread apart in the spaces N, as is the case in the succeeding spaces, when the number of the beans upon the belt has been reduced, thus permitting their freer movement.

This device is well adapted for separating any objects which are capable of rolling easily when perfect-such as pills, marbles, and shot.
