PETER H. IACKIE/OI CLINTON, WASHINGTON.
AUTOIA'I'IC PULVEBIZ ING CULTIFATOB.
Application l led December I2, 1084;. Serial No. 757,405.
The invention is a device for thoroughly breaking up orgrinding, and ulyerizing earth by a differential action tamed by two sets of rotary discs or plows.
The object of the invention is to provide a device that will thoroughly, break up, grind and pulverize earth by rawing it across the j earth once. 7 i Another object of the invention is to provide'two sets of blades which work together in suchja manner that one set wilLpick up the earth and force it upward between two downwardly moving members of the other set. v A further object of the invention is to,
provide a plurality of rotary plows arranged in two sets in which the forward set travels at a higher speed than the other set. And a still further object of the invention is to provide a machine having two sets of inter-woven rotary plows, which'is of a simple and economical construction.
With these ends in view, the invention embodies a machine having a lurality of rotary'plow like blades arrang in two sets that operate at different speeds and In which the rear sections of the front blades move upward between the forward sections of the rear blades.
Other features and advantages of the invention will appear from the followin description taken 1n connection with the rawin s, wherein igure 1 is a plan view of the machine. Figure 2 is a side view of the machine. Figure 3 is a view showing a blade of an alternate design.
Figure 4 is a similar view showing another blade of another alternate design.
In the drawings I have shown my device as it would be constructed wherein numeral '1 indicates the plow like blades, numeral2 the shafts upon which the blades are mounted, and numeral 3 the frame. I
The blades 1 may be made of flat discs with sections 4 cut intheir edges and parts 5 of the section 4 bent outwardly as shown. The remaining straight ed es 6 of the sections 4 may be shar ened if desired, and the e outwardly extending members 5, may also be sharpened. It is understood that the sections 4 may be made of any suitable sha e, and the parts 5 may all extend outwar y on the same side or w every alternate one may extend from the opposite side as shown m Figure 1. It is also understood that the cuttin edges 6 may be straight and the parts 5 s anting as shown on the forward blade in Figure 2, or
the .cutting edge slanting and the parts 5 bent on astralght line from the center as shown on therear cutter in Figure 2, or these may also be formed as shown in Figures3and4.
The hubs atone end have sprockets l5 and 16 on them as shown in- Figures 1 and 2, and a chain 17, which passes over the s rockets causes both of the shafts to rotate.
n the design shown, the sprocket on the rear shaft is somewhat larger than that on the forward shaftwhich Wlll. cause the forward shaft to rotate somewhat faster than the rear shaft. This difference of speed between the two shafts and the difference of motion between the rear section of the forward cutters or plows and the forward section of the rear cutters or plows causes a differential motion and the earth that is brought up by the blades of the forward discs is round between the downwardly movingb ades at the forward sections of the rear cutters. It will be observed that this action will not only break up the ground but will thoroughly ulverize it. The shafts 2 are supported in earings 18 from the frame 3; In the desi n shown,,however, it is understood that they may be supported in any suitable manner and the design of the frame may be changed to accommodate them, if necessary.
In the design shown, the lower part of the frame 3 made 05 ab rectangul' ar a,an tetone19and the seat frame SO are attache to it by hinges 21 and 22. A double-tree 23 is rovided about the tongue and thisis attached to a vertical loop'24, one end of which is pivotally held in a bearing 25 on the ton e and the other ivotally attached to the o fward end of t e frame 20 by a member 26. This will cause the pull to be transferred through the frame 20 to the rear portion of the frame 3 so that it will be exerted upon both the front and rear sides of the frame. It is understood that the member 23 may be replaced by a clevis or any other suitable means when it is desired to use a tractor or the like to draw the device. 7
A seat 27 may be provided at the rear of frame 20 and a lever 28 may be provided at the forward end by which the forward end of. the frame 3'may be raised or lowered fiat bar bent in a lit]:
through a rod 29, and the upper end of the rod 29 may be provided with a sprmg 30 by which it may be resiliently held upward.
It will be understood that changes may be made in the construction without departing from the spirit of the invention. One of which changes may be in the size of the machine, as it is understood that any number of cutters may be used, and they may be,. ar-
ranged in any suitable manner. Another change may be in the design of the shafts 2 or in the means for holding the discs or blades on them. Another change may be in the design of the discs or low blades, or in the use of any other suita le means for obtaining a similar efiect. And still another change may be in the design of the frame or superstructure as it is understood that any suitable frame or structure may be used.
The construction will be readily understood from the foregoing description. To use the device it may be assembled as shown and it will be seen as it is drawn across the ground, by any suitable means, the blades 1 will rotate 1n the direction of the arrows with the forward set of blades rotating at a higher speed than the rear set. As the points or cutting edges of the blades of the forward set engage the surface of the ground, they will draw themselves into it and as they move upward, they will pick up any lumps or large particles and can carry them upward until they engage the downwardly moving blades that are extending outward on the forward sections of the rear cutters, and these blades will engage the lumps or particles of earth so that the lumps or particles of earth will be ground 4 between the upwardly moving blades of the 1,e41,ses
forward cutters and the downwardly movin blades of the rear cutters. This action w1 thoroughly break up all the lumps or particles of earth and thereb actually ulverize the round over whic passes, so t at the ground may be plowed and pulverized or thoroughly harrowed with a single operation.
Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent, is
In a pulverizer, two sets of circular shovels on rotating shafts, the shovels of the forward set havin teeth with sharpened radially extending orward edges, dia onally extending rear edges which exten from the tips of the teeth to the bases of the succeeding teeth and surfaces extending outwardly from the diagonal edges of the said teeth, and the rear set of shovels having teeth with radially extending rear edges, diagonally extending sharpened forward edges extending from the tips of the teeth to the bases of the preceding teeth and outwardly extending flanges at their radial edges, sprockets with a chain passin around them on the said shafts, the sprocket on the said forward shaft being of a smaller diameter than the sprocket on the said rear shaft to retard the motion of the latter set of the said shovels and accelerate the motion of the said forward set, which action will assist in drawing the forward set of shjovels into the ground and at the same time cause the latter set of shovels to slip or slide through the ground to pile the soil between the two sets of shovels.
