COMMINUTING MACHINE.

Appucation filed April 12, 1928. serial N. 269,399,

j This invention relates to comminuting machines for rapidly reducing alfalfa and the like to form a stock feed and of that type including a comminuting head and a'grading cyiinder or screen for the passage of the finer particles of the feed, and the invention has for its object to provide, in a manner as hereinafter set forth, a machine of the class referred to having means to permit of the passage of ccarser particles of the feed to a point of discharge when it is not desired to have a fine ration, as would be had if the fine parpoint of discharge.

A further obj ect of the invention'isto provide, in a manner as hereinafter set forth, a machine of the class referred to including adj ustable means for `permitting of the pasticles of the feed alone have passed to the sage of coarser particles of feed to la pointv of discharge when desired.

A further object of the invention is to provide, in a manner as hereinafter set forth, a machine of the class referred to including means in the form of van adjustable by-pass for increasing the capacity of the machine.

A. further object` of the invention is to provide, in a manner as hereinafter set forth, a machine ofthe class referredfto with an adjustable by-pass for the feed` for use when the farmer does not care to 4have as yfine a ration as would be obtained providing it was run all through the cylinder or screen and further whereby the capacityof the machine is increased when the` by-pass is open.

Further objects of the inventionl are to provide, in a manner as hereinafter set forth, an adjustable by-pass for'use in comminuting machines of the class referred to/and which is simple in its construction and arrangement, strong, durable, thoroughly efficient in its use, readily installed in the machine, conveniently opened and closed, as well as adjustable, and comparatively inexpensive to set up. i

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of arts as hereinafter more specifically described, and illustrated vin the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within' the i `scope of the claims hereunto appended. j

Inthe drawings whereinlile reference characters denote corresponding parts throughout the several views Y Figure lis a vertical sectional view of a comminuting machine, of that type including a grading cylinder and further illustrating an adjustable byepass, in accordance with this invention, positioned relative to the 'comminuting head and grading cylinder and with the by-pass closed.

Figure 2 is a fragmentary view in section illustrating the by-pass open.

An adjustable by'pa`ss, Ain accordance with this invention, is shown as installed in acomminutingmachine of that type illustrated by Letters Patent. 1,190,499, July 11, 1916, in which a rotatable grading ,cylinder for the passage of the finer particles of the vfeed forms a partJ thereof, but it is to be understood that an adjustable bypass, inlaccordance with this invention, may be installed in any type of comminuting machine for 4which :the by-pass is found applicable and whether the lgrader is in the formuof a rotatable cylinder `or stationary` screen. l, f

y It is thoughtunnecessary to specifically describe the elements ofthe machine, as such specific details can be ascertained by reference `lto Letters Patent aforesaid, `and such elements will be referred to generally and in this con- 4 nection 1 indicates a rotatable cornmijnuting element, 2 thefrotatable grading cylinder or `sifter arranged below, the element 1, 3, 4

centenand llower feed Arolls respectively arranged adjacent to the element 1 and cylinder 2; 5 upper feedroll, 6 feedinglmeans for stock, 7 cover for the element 1'; 8 covers for lrolls 3, 5; 9 feed throat, 10 cover for throat 9,

11 upper ledger plate, 12 upper ledger plate holder, 13 lower ledger plate, 14 lower ledger plate holder, 15 lower section of hood 7, 16 mainframe or housing, 17 feed throat side, 18 perforated, pivoted segmental sections of the cylinder 2 g 19 guide for controlling the sections 18 of cylinder' 2; 20 ,main frame, 21

- Support for frame`20; 22 front tie barplate, v23 rear tie bar plate and 24 discharge conveyor or wormarranged in the top of frame 2O and below the lower ends of plates 22, 23.

. The plates.22,.23 "are disposed at opposite in-v clinations with respect to each other and between the lupper portions ofthe plates 22, 23,

as well as spaced therefrom is the guide 19.

' 22 whereby a passage 25 is provided nor-v mally closed by a pivoted plate 26 carried byA It will be stated that two guides are employed, one at each end ofthe cylinder 2. rIhe foregoing elements are illustrated so that the adaptation of an adjustable by-pass in ac` cordance with this invention and for the purthe comminuting element 1 and said' cylin-V der 2 is further spaced from the front plate the lower ledger plate holder 14. The plate 26'is pivoted at its outer side, to the plate 14, as at 27. The plate 26 is provided on its outer side with a-pertured ears 28, only one of which is shown and through'which eX- tends the pivot 27, the latter also extending through or connected with the bottom of the plate 14.y yThe plate 26 is of a length substantially the same as the length of the ele.n ment 1 and cylinder 2 and said plate 26 constitutes agate for closing the passage 25 and will be hereinafter termed a gate. The gate at each endl andy at its inner side is formed with a depending flange as indicated at 29.

The width of the gate 26 is Asuch that when it is in a position to close the'passage 25 it will extend into close proximity to and between the guides 19. l

The opening movement of the gate 26 is adjusted, andl the means'for adjusting the gate 26 also provides for not onlyretaining it in adjusted position, but also lretaining the gate26 in closed position for shutting olic communication between the upper portion of the passagey 25 and the lower portionthereof. The means coacting with the gate 26 .for the purpose ofretaining it in closedl position as well as inadjusted position, consists of a screw 30 having its inner end riding against the lowerA face'lof the lgate 26. The outer end of the screw 30 is provided with an enlarged head 31 to provide for'theconvenient shifting of the screw. The plate 22 is formed with an opening 32 having a threaded wall with which engages the screw 30. The plate 22 is also provided with a boss on its outer face and adapted to be engaged by the reduced inner part 33 of the head 81. 1

When the gate 26 is in closed positionV the vcommin'uted material will be caused to pass solely through the cylinder 2'but the comminuted material must be of such size as to pass through the openings in the sections 18. If `it be desired to permit of the discharge of the coarser feed which? cannot pass through the sections 18, the gate 26 is adjuste'dto the desired extent to open the passage 25 whereby the said coarse material can pass between the gate and the cylinder 2 to the point of discharge which is the conveyor or worm 24.

The gate 26, when 'adjusted in position to l lsaid by-pass.

close the passage 25, as illustrated in Figure i v 1, is slightly inclined in a. downward direction from its pivoted end -to its free end, and as the screw 30 is withdrawn from the passage 25 by the rotation of the screw, the gate 26 is actuated by gravity inthe same direction as the direction of travel of the feed particles through the passage. By only partially withdrawing the screw 30 from the passage 25, the gate 26 may be adjusted at the desired inclination to close any predeter mined portion of the passage. l

In some instances the farmer does not desire a ration formed of the iinest particles ofthe feed, that is to say those particles which ypass through the sections 18 of the cylinder and if such loe the case the gate 26 is opened to the desired extent so that the coarser particles, not vpassing 'through 'the cylinder 2, will be permitted to pass between the gate 26 and the cylinder 2 to the conveyor er worm 24 ywhere the coarser particles would mix with those finer particles which have passed through the cylinderk 2, or if none of the liner' particles are at the conveyor or worm 24, then there will be no admixtur'e of the' coarser particles with the hner particles. The opening of the gate26 increases the capacity of the machine.

The gate 26, inconnectionwith the adjusting screw 8O and passage 25 providesa by-pass whereby the machine can be controlled so that the coarser particles of the feed will be permitted to pass to a point of discharge. The'gate 26 can be so adjusted that liner particles land coarser particles can be simultaneously'supplied to the conveyor or worm 24, the finest particles passing through the cylinder 2 andthe other particles between the gate 26 and thecylinder 2.

Itis thought the many advantages of a. comminuting machine of the class referred` to provided with a by-pass,in` accordance with this invention, can be readily under. stood, and although the preferred embodiment of the invention is as illustrated and de scribed, yet it is to be understood that changes in the details of construction can `be had which 4will fall withinthe scope vof the invention as claimed.
