SPECIFICATION forming part of Letters Patent No. 440,036, dated November 4, 1890.
Application filed August 13, 1888.
useful Improvements in Pulverizers for Mellowing Fall-Plowed Land and Sod, of which .the following is a specification, reference bein g had therein to the accompanying drawings.
This invention relates to improvements in machines for pulverizing ground; and it consists of an adjustable frame, hereinafter described, and pulverizing-teeth of peculiar construction.
In the drawings, Figure 1 is a plan view of the entire machine. Fig. 2 is a vertical section on the line so as, Fig. 1; Fig. 3 is a partial rear View. Fig. 4 is a side elevation of one of the beams and one of the teeth orblades attached thereto. Fig. 5 is a front edge view of one of Fig. 6 is aside elevation of one of the blades. Fig. 7 is a section on the lineyy of Fig. 6. Fig. 8 is a side view of one of the adjustable clamps for the blades. Fig. 9-is aface view of a washer used with the blade-clamp. Fig. 10 is a detail view of a bracket.
said bracket, so that the beam A and brackets B form an arched axle.
To the forward end of the timbers O,'which are rigidly connected to the beam A by the brackets B, is pivotally secured a transverse beam E, to which latter is pivoted a series of beams F for pnlverizing-teeth G, hereinafter referred to. The pivotal connections between the beam E and beams F consist of brackets H.
Centrally on the beam E is erected a standard I, provided with holes 1'. This standard pivotally supports a pole K by means of a bolt 70, the holesi permitting suitable vertical adjustment." The pole extends rearwardly from the standard, and near its rear end is connected pivotally to a transverse beam L by means of a bracket Z.
The beam L is parallel to the beam E and carries, pivotally, the forward ends of a series Serial No. 282,596. (No model.)
of beams M, carrying pulverizing teeth or blades G. The beams M alternate with the beams F and extend farther rearward.
To the beams E and L are rigidly secured rearwardly-extending timbers N, carrying at their rear ends a transverse timber 0, above the beams F M, and forming a pressure-bar, as will presently appear.
The pressure-bar O is provided with a se ries of holes through which pass headed bars or rods P, connected to the beams F M and surrounded by springs R between said beams and the said pressure-bar. Flat or other shaped springs may be used. As is evident, the spring-surrounded rods P form yielding supports for the rear ends of the beams F M, so the teeth G may readily pass obstruct-ions.
S designates the seat-supporting timber pivoted to and extending on each side of the axleA. The front end of the said timber S K, so that the drivers weight will in a meas ure counterbalance the weight of the pole and machine. On the axle A, adjacent to the timber S, is a rack-plate T for engaging a hand-lever U, connected to the rear end of the pole by a link V. The hand-lever and rack may be of any suitable construction.
In Fig. 2 the parts are shown in the raised position. If now the lever be moved, the rear end of the tongue will drop, the horses necks being the fulcrum. The cross-beams E and L, being connected to the pole, will also fall, and the whole frame will move on the wheelspindles as a center, since the beamE is pivotally connected to the timbers C and the latter are secured to move with the axle A. This operation will be at once apparent from an inspectionof the drawings.
I will now proceed to describe the teeth or blades and the connections to the beams,'as shown in Figset to 9, inclusive. The teeth or blades G each consist of a shank A, a main or body portion B, and abent or angular portion 0. The body B and angular portion C have one edge sharpened throughout, and the other edge is preferably thickened to strengthen the blade. As will be seen from Fig. 5, the body port-ion may be at an angle to the shank, and the-angular portion 0 is slightly twisted, as shown more clearly in Figs. 6 and 7. v
When in operation, the body portion of the is pivotally connected to the pole or tongue blade presents a knife-edge in the direct line of draft and offers but the minimum of resistance to the passage of the blade through the ground. The angle portion 0', however, presents the cutting-edge at an angle approximatingforty-five degrees to the line of draft and about the same angle to the vertical, with the said cutting-edge directed downward and rearward.
It will be seen that the relative angle of the portion 0 to the vertical may be varied by adjusting the angle of the body portion to the beam. The shape and angle of the portion 0 tends to force the tooth or blade into the ground; but being restrained by the frame the earth is lifted and caused to flow over the said portion, being thereby pulverized. It is to be noted that the earth is notturned over, as is done by a plow, but is lifted only-an action which has been found to readily dis integrate all lumps. The sharpened body permits the tooth to be sunk deep into the ground.
The special object I have in view in constructing the pulverizing-teeth in the peculiar manner shown and set forth is to compel or force them to automatically sink deep into the soil when the machineis drawn along over the surface of the ground, and thus provide for the deep and thorough cultivation and pulverization of the same. The special advantage of this construction of tooth is that this deep cultivation and pulverization is thoroughly accomplished with the least amount of resistance and without turning over the soil, thus permitting of the use of a comparatively light frame and harness.
Each tooth is securedto its respective beam by a casting. (Shown in Fig. 8.) This consists of a bracket D with a central bolt-hole, and a segmental off-set E, having a roughened or toothed face to receive a similarly-constructed washer F. (Shown in Fig. 9.) The casting is secured to the beam by two bolts, one of which passes through the shank A of the tooth and the bolt-hole in the body of the bracket, and the other through the washer F and the segment E. The body D is so constructed as to receive the shank A and hold the same at an angle, as shown, while the segment permits the adjustment of the bracket around the bolt holding the blade, the corrugations preventing further movement when adjusted.
I prefer to have one blade to each beam, with the blades on one side of the machine turned in a direction opposite those on the other side, as plainly shown in Fig. 1. It will be seen that the angle of the blade or tooth to 'both the vertical and horizontal is such that should it encounter an obstruction it will move upward and ride over the same, the rod P and springR permitting such movement.
I do not confine myself to the exact construction and arrangement of parts shown, but may vary the same Without departing from the spirit of my invention.
Having described the invention, what I claim is-- 1. A pulverizer consisting of a pivoted frame, a transverse beam pivoted thereto, tooth-carrying beams pivoted to said transverse beam, a tongue or pole connected to said beam, another transverse beam also connected to the pole, tooth-carrying beams pivoted to the latter transverse beam and alternating with the other tooth-beams, and means, substantially as described, for adjusting the frame and beams, as set forth.
2. The combination, in a cultivator and pulverizer, of a pivotally-supported frame, a transverse beam pivotally connected to this frame, tooth-carrying beams pivoted to this transversebeam,rearwardly-extending beams N, connected to the said transverse beam, a pressure-bar supported upon these beams N, yielding connections between the pressurebar and tooth-beams, and means for adj usting the said parts, substantially as described.
3. The combination of the axle-beam supported upon transporting-wheels, forwardlyextending beams O, rigidly connected to the axle-beam, a transverse beam E, pivotally connected to the said beams C, a pole or tongue pivotally connected to this beam E, another transverse beam L, pivotally connected to the tongue,tooth-carrying beams pivotally connected to the said beams E and L, rearwardly-extending beams N, supported upon the transverse beams E and L, a pressure-bar 0, supported upon the beams N, yielding connections between the pressure-bar and tooth-beams, toothbeams, and means for adjusting the parts.
4. The combination of a pivoted frame supported upon wheels, a transverse beam hung to this frame, beams hung to this transverse ICC beam and provided with cultivating means,
the tongue pivotally connected to this transverse beam, a beam S, supported upon the axle of the frame and pivotally connected at its forward end to the tongue, this beam carrying the drivers seat, and a lever pivotally supported on the frame and connected to the rear end of the tongue, substantially as described.
5. The combination of a pivoted frame mounted upon Wheels and provided with forwardly-extending arms, a transverse beam hung to the forward ends of the said arms and provided with cultivating means, a tongue connected to the said transverse beam, and an adj usting-lever mounted on the frame and connected to the said tongue, as and for the purposes described.
In testimony whereof Iaffix my signature in presence of two witnesses.
