WILLIAM A. BARBER, 0F WASHINGTON VERTICAL SICKLE DIVIDR FOR Application lled November when the grain stands up but when the grain is tangled and down and full of vines, the arrangement provesl very inefficient. The swathl of tangled grain, cutl by` the binder, hangs over the divider board and stays there vuntil the operator stops his machine and clears the board.- lf the grain is full of vines the efliciency becomes still more impaired. By the use of my improved structure, such conditions are entirely done away with because long before the grain` is cut by the binder sickle, a clean-cut positive separation is made between the binder swath and the uncut grain. By the use of the device desci-ibed herein clogging of the elevators and the binding mechanism of a binder is practically eliminated there being a continuous and uniform movement of the-grain as soon as out by the binder sickle to the elevators and binding mechanism. This device causes a clean-cut, straight and verti cal swath wall, regardless of the condition of the grain. Wrapping of the grain wheel is also done away with and the power needed to run the attachment is compensated for by the efficiency which is attained.-

The structure of my improved device is exceedingly simple, comparatively inexpensive to manufacture, strong and durable, very reliable, not likely to easily become out of order, and otherwise well adapted to the purpose for which it is designed.

With the above object in view, the invention resides in certain novel features of construction, and in the combination and ar-k rangement of parts as will be hereinafter more fully described and claimed.

Referring to the 4drawing in detail it willV .l

be seen that 5 denotes aframe of conventional construction which i's mounted for` wardly `of ,the ,binder (not shown) riny they usual well-known manner for supporting the sickle barconstruction 6which is disposed yhorizontally and is driven `in the usual wellknown manner. The frame also supports the conveyor 7of well-known construction.V In the y present instancey the sickle-bar struc-1k ture 6 and the'` vconveyor 7 are operatedr through the shaft 9 which in turn is op-v eratedby chains 10. TheV supporting wheel 11 is mounted in the usual `well-known man? ner to one side of the frame -5. #It is ,now the common practice to mount a divider board to one side of thisframe 5. However, in my construction this divider board is done away with and there is utilized'afvertical sickle bar construction denoted gener` allyby'the letter Swhich is disposed forwardly ofthe sickle bar lstructure 6 and to one side thereof in alinement with the space usually occupied by the divider board, that is, approximately in front of the supporting wheel 11. The numeral 12 denotes the divider .sill which is attached to the frame at 14 at its rear end and extends laterally and then forwardly and merges into a `forward extension which is bent at a point forwardly of the sickle structure 6 inwardly and has a bracket 15 at its forward end to which a flattened end 16 of a tube 17'is attached as at 18. The rearv end of this tube is bent iml and engages over oneof the guard fingers 19 of the vertical sickle structure S. Manifestly the tube 17 is of rigid character, and from this it follows that the tubeV 17 contributes to the dividing capacity of the sill 12 without materially increasing the Weight of said sill, and at the same time thetube 17 by receiving the lowermost finger 19 of the upright cutting mechanism assists in the maintenance of said upright cutting mechanism in working position. This vertical sickle structure S includes a vertical stationary bar 20 having the usualngers 19 projecting forwardly therefrom. The bar 'y 20 is arranged at the forward end of an mu v upright supplemental frame made up of an inclined bar 20X connected at one end to the sill l2 and at its upper end to the upper end of the bar- 2O and appropriately' braced bars 2lX and 22 interposed between and connected to the sill l2 and the bar 20X. A movable cutter bar 21 is mounted in the stationary bar 2O and has knives or cutters 22 which ijnovefi-n the-fingers 19 as is clearly illustrated in Fig. 4. A head 23 is attached to the movable bar 2l and is engaged with a pitman 24 and isalso engaged with the crank of a crank shaft 25 which extends rearwardly being journaled in bearings 26 and 27 and at its rear end is operatively connected with a chain 28. The chain 28 is operatively connected with the shaft 9.

It is' thought that the construction, operation, and utility of this invention will now be clearly' understood without a more detailed description of the parts thereof. It willbei noted' that as the binder or other grain-cutting mechanism moves forwardly a clean-cut vertical swath wall is formed regardless of the condition of the grain. This eliminates all' the undesirable.features incident to2 the usual* divider board struc ture. v l

The present embodiment of the invention has been. disclosed in detail merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It is apparent that changes in the details of construction, and

in the combination and arrangement of parts may be resorted. to' without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my inventionwhatv divider sill having its rear end fixed to the 'i frame and terminating in frontof and to one side of the first namedl cutting mecha` nism, a bracket fined on the forward end of said sill and having a rearwardly directed arm spaced above the sill, a rigidk tube connected at one end to said arm of said bracket and: extending upwardly and rearwardly from said arm and receiving in its rear end the loweisnost finger of the second named cutting mechanism, and an upright supple-` mental fraine connected with 'the upright bar of the second named' cutting mechanism and the frame `and arranged in rearl of said `upright bar andhaving a rearwardly and downwardly inclined topbar and also having intermediate upright bars and braces for the latter.

In testimony whereof I aihx my signature.
