THRESHING- AND SEPARATING MACHINE.

Specification of Letters Iatent.

Patented Mar. 1st, 1916.

Application filed June 24, 1914. Serial No. 847,032.

T 0 all whom it may concern:

Be it known that 1, PETER S'ronzUK, citizen of the Dominion of Canada, residing at the village of Ethelbert, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Threshingand Separating Machines, of which the following is a specification.

My invention relates to improvements in grain threshers and separators, and has for its object primarily, the improvement of the means for separating the grain from the straw after these have passed through the usual cylinders and concave and secondly the means for operating the improved separating decks.

With these objects in view the invention consists in the novel construction and combination of elements hereinafter set forth, and fully illustrated in the accompanying drawing, in which Figure 1 is a side elevation of a separating machine, a portion of the siding being broken away to show the separating racks or decks. Fig. 2 is a plan view from above of the separating racks apart from the rest of the machine. Fig. 3 is a sectional end view of the interior of the machine taken upon the line AB in Fig. 1. Fig. 1 is a view from below of the crank movement by which the separating racks are operated.

Referring to the drawings, in which similar'characters of reference refer to similar parts throughout the different views, C indicates the bodyof the machine having therein suitably placed and housed the cylinder 1 and concave 2, adapted to perform their usual functions and deliver the straw and grain in their 'threshed condition to the separating racks-behind. The separating racks are divided into groups, each of which may consist of as many individualracks as may seem advisable, each group being separate and distinct from the others, and. separately supported and operated. 1

In simple form as shown herein, the racks are divided into two groups D and E the members 3 and 5 of the group D being alternately placed to the members 4 and 6 of the group E. The members of the group D are supported at one end by the blocks 7 and 8 carried by the cross bar 9 in turn carried by the rods 10 and 11 pivotally secured to the horizontal framepieces 12 and 13 and at the opposite end by similar blocks not shown but carried by the cross bar 14 and the pendulous rod 15 secured to the frame piece 13 and a similar rod on the opposite side of the machine notshown pivoted to the framepiece 12. Simllarly the members 1 and 6 of the group E are supported at one end by the blocks 16 and 17 carried by the cross bar 18, in turn carried by the rods 19 and 20 pivoted to the horizontal frame pieces 12 and '13, and at the opposite end by blocks not shown but carried by the cross bar 21 and the pendulous rod 22 pivoted to the frame piece 13, and a similar rod on the opposite side of the machine pivotally connected to the frame piece 12. .At this point it will be noted that still another cross bar 23 is shown in Figs. 1 and 2 crossing the machine and which bar is connected with the members at and 6 of the group E, and supported by rods, one of which 24, is shown in Fig. 1.

F indicates the grain deck or gather board, locatedbelow the separating decks and serving to receive the separated grain and carry it to the fanning mill shown as 25 in Fig. 1. Below the gather board F and protected thereby from falling grain and dust is the crank mechanism G, a bottom view of which is shown in Fig. 4. This consists of a shaft 26 journaledat 27 and 28 to the lower side of the sill pieces 29 and 30 ofthe frame of the machine. The shaft 26 is provided in its length with the oppositely disposedcranks 31 and 32, and 33 and 34, connected respectively by the rods 35, 36, 37 and 38 with the rocking arms 39, 40, 11, and carried by the shafts 13 and n ournaled to thesills 29 and 30. Rods 45 and M3 connect the rockingarms 41 and 39 respectively with the ends of the cross-bar18, which project as will be noted in Fig. 1, through the are shaped openings 17 in the sides of the body 6 of themachine. Similarly, the rocking arms 10 and 42 are connected with ends of the cross bar 23 by rods, only one of'which, indicated as. 48, is shown, in Fig.

1. The rods 15 and- 16 it will be noted by reference to Fig. 3, have their lower ends turned at right angles to form a horizontal portion designatedon each respectively as 45* and 4:62 the rod 48 and its corresponding member being provided with similarly turned portions for a similar purpose. The ends of the turned portions of the rods are adapted to reach and be selectively entered in the openings shown at 39 and 10* in the swinging members 39 and 40 in Fig. 1, .it

being understood that similar openings are provided in the corresponding swinging members not shown in the drawings, to receive the ends of the horizontal portions of the rods pertaining to each. It will be noted that there is a plurality ofthe openings 39 and 40* in the respective members and that disposal of the turned portions of the rods in different openings will operate to diminish or increase the length of the movement of the straw decks as'the openings made use of are close to or removed from the pivotal points 43 and 44 of the respective members. Thus the motion of the cranks is transmitted through the rocking arms and rods to the groups D and E of separating racks, imparting to them an alternately reciprocating and rising and falling motion with a tendency to carry in a direction away from the cylinder and concaves 1- and 2 toward the rear'end of the machine.

The'separating racks themselves it will be noted are of novel construction and clesigned to have the largest possible separating capacity in proportion to their size. Each of the racks consist of the longitudinally extending spaced apart sides 49 and 50 which are of equal dimension from end to end. Along the upper edges respectively of the sides 19 and 50 are the substantially right angled triangular opensided erections II and H formed by the upwardly and rearwardly sloping pieces 51 and the downwardly sloping pieces 52. The members H and H are much larger than the serration 'orfish back usually seen in this type of ma chine, and they are connected each to each bythe lateral strips 58, 5d, 55 and 56 disposed in spaced relation along the faces of the upwardly sloping pieces 51 and secured thereto. It is preferable that these strips be quite narrow and, four in number though the number may be varied should it appear advisable.

It will now be noted that the separating racks as'described arepr'ac'tically of skeleton construction, and that the lateral slats 58, 54:, 55' and 56, while serving to prevent the straw from dropping through along with the grain separated by agitatiomdo not impede-the dropping of the grain, the area of the openings between the slats, owingto their being positionedupon the up sloping pieces 51, being still greater than would be the open. area between the sidesI-I and H if measured upon the plane of their upper edges and without the erections H and H with their connecting lateral slats.

The open construction of the triangular members H and H in addition to its value as 'a means of increasing the separating area on the surface of theracks without unduly adding to their weight, also adds greatly to means revolves the crank shaft 26, the'crank movement being transmitted as previously mentioned through the rocking arms and rods to the groups D and E, these are caused to reciprocate and agitate the threshed straw and grain received from the cylinder and concave, passing the material toward the tail end of the machine.

7 Owing to the peculiar skeleton construction of the separating racks, as described, 7 the agitation lmparted is very thorough, and

grain cannot be carried past the openings in' the racks to be blown out with the straw on to the stack and lost, which is the mainv point sought to be attained in the designing of the machine. a

Having thusfully described my said invention what I claim is 1. In a threshing machine,a straw deck comprising a plurality of oppositely reciprocated sections,'each of said sections having a pair. of spaced side walls provided upon their upper edges with upwardly pro ecting open sided triangular members, and transverse slats connecting the members on one side wall with those onthe other.

2. In a threshing machine, a straw deck comprising a plurality of sections alter nately placed and connected to form oppositely reciprocated groups, each of sa d sections having a pair ofspaced side walls protransverse-slat-connected triangular ,membersghaving a rearward inclination- .105 vided on their upper edges with open'sided i 3. In'a separating machine, a strawdeck having longitudinally extending spaced side walls and open sided triangular mem .bers on the upper edges of each sidewall corresponding with those on the other, lateral slats connecting the points of the members on one side wall with the points of the corresponding members on the other side wall, slats similarly connecting the bases of the members and connecting slats intermediate the slats mentioned.

In testimony whereof, I aflix my signature in the presence of two witnesses.
