SEPARATING MECHANISM.

To all lwhom it may concern:

Be it known that I, JOSEPH Lorman, a citizen of the United States, residing at Atchison, in the county of Atchison and State of Kansas, have invented a new and useful Separating Mechanism, of which the following is a specication.

This invention relates more particularly to machines for separating cereals and other materials and removing foreign matter therefrom, and while especially suitable for removing oat groats from oats, shelledA from unshelled rice, and the like, it is by no means limited in its usefulness to treating such articles, but it may be employed for various other materials.

The primary object is to provide a novel compact structure, which will have a oomparatively great output and require a relatively small amount of power.

The separating mechanism per se, constitutes the subject-matter of a separate application, filed simultaneously herewith, and having Serial No. 431,062, and the present case embodies more particularlythe operating and supporting mechanism therefor.

One of the principal objects of this invention therefore is to provide novel means that will constitute a swinging` support for the separating mechanism, and will effect the reciprocation of the same, in other words, cause said mechanism to move in substantially the same plane throughout its stroke.

A further object is to provide operating means whereby the length of the stroke of the separating mechanism can be varied as desired, and still another and important object is to provide a machine that is effectively cushioned at the limits of its movement, thus eliminating to a material degree shocks and jars upon the driving means.

The preferred embodiment of the invention is illustrated in the accompanying drawings, but it will be evident from an inspect-ion of the claims hereto appended, that this structure is open to change and modiication.

In said drawings z-Figure 1 is a side elevation of the machine. Fig. 2 is an end elevation of the same. Fig. 3 is a vertical cross sectional view. Fig. 4- is a vertical longitudinal sectional view. Fig. 5 is a face view of the adjustable eccentric, showing the opposite side to that illustrated in Fig. 4. Fig. 6 is a detail view of one of the carrier Specification of Letters Patent.

Patented Mar. 8, 1910. Serial No. 431,061.

links illustrating in dotted lines the different positions assumed thereby. Fig. 7 is a top plan view of one of the cushions. Fig.' 8 is a longitudinal sectional view through the same.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the particular form of construction disclosed, a supporting frame 9 is provided on which is mounted a shaking separator body 10 that is fully disclosed in the co-pending application to which reference has already been made. This body is fastened to a frame 11, and to the under side of said frame, are secured by means of brackets 12, suitable outstanding pivots 13. These pivots are engaged in the upper ends of swinging carrier links 14 that are provided 1n their lower portions with longitudinally disposed slots 15. Other pivots 16, outstanding from brackets 17 that are fastened to the supporting frame 9, are engaged in the slots 15. Journal boxes 18, fastened on the lower portion of the supporting frame, form bearings in which rock shafts 19 are journaled, and secured to the ends of said rock shafts, are short depending crank arms 20 terminating in crank pinsor pivots 21 that are engaged in the lower ends of the carrier links. It will be noted that the distance between the axes of movement of the rock shafts 19 and pivots 21 is less than the distance between the aXes of the pivots 21 and the pivots 16.

A drive shaft 22, operated from any suitable source of power, is journaled on one end of the supporting frame, and Xed to said shaft, is a hub 23 on which is slidably mounted an eccentric disk 24. This disk has a slot 25, through'which the drive shaft 22 passes, and it is provided with other slots 26 located on opposite sides of and parallel to the slot 25. Holding bolts 27, secured to the hub 23, pass through the slots 26, and clamping nuts 28 are threaded on the bolts. A11 adjusting stem or bolt 29 projects from one edge of the hub 23 and passes through an' ear 30 outstanding from the eccentric disk 24, while nuts 31, threaded on the stern 29, abut against opposite sides of the ear 30.` An eccentric strap, preferably comprising sections 32, surrounds the disk 24, the sections being fastened together by bolts 33, and secured to the strap, is a pitman 34,

which is pivoted as shown at B5 to a depending bracket 36 secured to the central portion of the frame 11.

Oppositely disposed cylinders 37 are secured on top of the supporting frame 9 at the ends thereof, and are provided in their sides with ports 38. rlhey also have outer closed ends, from which project vent nipples 39 having turning valves 40 therein. Pistons 41, operate in the cylinders, and adjustably secured to said pistons, by nuts 42, are piston rods 43 fastened as shown at 44 to the ends of the shaking' body frame 11.

It will be evident that if the drive shaft 22 is rotated, the eccentric disk 24 will be revolved, thereby moving the pitman 34 back and forth and causing the frame 11 with the separator body 1() to shake. As a result, the links 14 will be swung back and forth, but their upper ends, or in other words, the pivots 13, will not move in the arc of a circle, but in a substantially horizontal plane. In explanation of this, it will be evident that inasmuch as the pivots 16 are stationary, the lower ends of the links 14 will be swung back and forth, thereby swinging the crank arms 20 of the rock shafts 19. Inasmuch as these arms are shorter than the distance between the

pivots

21 and 16, the links will be caused to move longitudinally of the pivots 16 during their swinging movements, and this movement is just sutlicient to cause the axes of the upper pivots 13 to remain in the same horizontal plane, as will be clear by reference to Fig. 6. The amount of shaking movement ofthe separator body can be readily varied, for by loosening the nuts 2S and turning the nuts 31, the disk 24 can be moved to different positions on the hub 23 and reclamped, thus bringing the center of said disk nearer or farther away from the axis of the shaft 22. The cylinders 37 and pistons 41, operating therein, constitute cushions. Said pistons, as will be noted by reference to Fig. 8, move past the ports 3S, and their movements beyond the ports, are not obstructed. After passing said ports, when moving inwardly, however, the air in the closed ends of the cylinders will be compressed, thus producing a continuously augmented resistance until the limit of movement is reached. The vents in said closed ends of the cylinders can be opened to any extent desired in order to secure the best cushioning eect possible.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention, will be apparent to thoseskilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departinglfrom the spirit or sacrificing any of the advantages of the invention.
