HARROW.
SPECIFICATION forming part of Letters Patent No. 262,820, dated August 15, 1882.
Application filed February 3, 1882.
To all whom it may concern:
Be it known that I, FREDERICK NrsHwITZ, of Millington,in the county of Morris and State of New Jersey, have invented certain Improvements in Barrows, ot' which the following is a specification.
The invention consists in certain novel features and organizations, the details and operation of which will be fully set forth and claimed hereinafter.
In the accompanying` drawings, Figure 1 is a vertical section; Fig. 2, a plan view; Fig. 3, a detail view, showing cutting-disks mounted on the gang-bars; and Fig. 4 is a detail plan view, also showing cutting-disks.
The draft-frame or tongue-frame is shown as composed of the pole or tongue A, the draftbar or whiflle attachment B, which is placed between the branches or hounds ofthe tongue, a curved or semicrcular strap or bar, C, on the bottom of the tongue and draft-bar, and a strap or brace, G', which extends from the ends of the curved bar across the top of the tongue and draft-bar, the parts all being securely and rigidly bolted together. This is mere detail and may be varied.
The forward gang-bar, D, which also constitutes a crusher and leveler, is hinged at d to the draft-frame, preferably somewhat in front of its forward face, as shown. Rearwardlyprojecting straps or arms E E 'are attached to this gang-bar at suitable points, and have eyes in which loops F F from the rear cutter-bar, G, engage so as to form the hinge-jointsff. Of course the gangs may be hinged in other ways.
Theseat-standard H is pivoted on the tongue or draft frame, and is supported at h h upon the rear gang-bar, G, by pivoted supportingrods at a point in rear of the hin ge-joints f f.
A lever, I, pivoted on the tongue or frame works preferably in a longitudinal slot in the seat-standard, and is held in any desired position by a notched dog or detent, i, pivoted onv the seat-standard and engaging with a loop or eye on the lever. The rearwardly-projecting bent end I2 of the lever is connected by a link, K, with the seat-standard. This link may be adjusted in the slot in the seat-standard by means ofthe set-nut 7c, if desired, to modify the relation of the gangs to the frame and change the range of their adjustment.
(No model.)
The purpose and operation ofthe above organization will be fully set forth when the details ofthe machine have been described.
The front lower corner or edge of the gango,
bar D and of the cutter-bar,Garecovered with iron angle-strips Llsh'own in Fig. l.) The flat ends m n of the barrow-teeth M N, which form the surfaces of attachment tothe bars, are inserted under the edges of the angle-strips to form a snug and neat connection. The angle-strips and teeth are secured by suitable bolts. The teeth M on the front gang-bar are uniformly curved to one side relatively to the line of draft, while those on the rear bar are uniformly curved in the opposite direction; and it will he observed that they are so arranged that the teeth in the rear gang will cut out the spaces left by those in the forward gang, as is clearly shown in Fig. 2. No claim is, however, made herein to this special organization.
Between the teeth on the front gang-bar are -placed flat spurs, disintegrators, or crushers 0, which are secured under the angle-strip, as the teeth are, and project rearwardly from the bar at or about in line with its lower face, and are slightly turned up at their ends.
It will be observed that the flat portions m of the teeth M also extend a short distance in rear of the gang-bar. The spurs or crushers O and the iat parts m of the teeth constitute a substantially metal-faced, ribbed, open-slotted, or comb-like clod crusher and leveler.
The teeth M are, as above mentioned, straight and fiat for a short distance in rear of the gang-bar, and are then twisted around to present a curved cutting-edge to the soil. The teeth N ou the rear cutter-bar are similarly shaped, though the dat portions do not extend much, if any, to the rear of the bar, there being no occasion for such an extension in this gang. These teeth are provided with wings or earth-turning portions N', which are somewhat longer than the teeth proper. No claim is, however, made herein to a tooth ot' this construction, such claim being made in another application for patent filed by me.
The weight of the driver and ofthe frameis supported on the rear gang or cutter bar through the pivoted supporting-rods, and is in part transferred through the hinge-joints-f f to the forward gang bar or crusher, as will IOO be seen upon reference to Fig. 1. To make this more clear, assume that the teeth in the rear gang constitute the fulcrum of that bar. Now, the weight being applied to the front of the fulcrum will press down the hinge-joints ff and transfer part ofthe weight to the forward gangbar, which is fulcrumed at its connection with the frame.
The relation of the gangs to the soil may be varied by operating the lever. Thus, if the lever be drawn toward the driver it will tend to draw the tongue and seat-standard toward each other and to press the rear gang down, and the power being applied in rear of its hinge-joints ff will cause the teeth thereon to assume a more upright position relatively to the ground. At the same time the front or pivot of the Crusher-bar is raised, and as a pressure will be exerted by the depression of the rear bar at the hinge-jointsfj'in the rear of the hinge-connections d (l of the front gangbar the teeth on that bar will also be caused to assume a more upright position. To describe this operation in another way, the joint between the link K and lever may be said to forni a fulerum, from which the frame an d forward gang bar or Crusher are raised. In this view the teeth of the front gang form the fulcrum on which the bar rocks, and consequently the raising of the bar turns the teeth down and causes them to assume a' more upright position. The raising of the front bar lifts the hinge-joints ff, and, turning the cutter-bar upon thefulcrum h,formed bythe joint ofthe supporting-rods and cutter-bar G, depresses the teeth in the rear gang and causes them to assume a more upright position.
It will thus be seen that by operating the lever the relation of the teeth to the ground and to the frame or tongue may be varied as occasion may require.
My improved machine is free to dex to conform to undulations and inequalities of the ground, and will thoroughly operate upon the surface traversed. In passing over the tield any obstruct-ion, undulation, or rise in the ground will cause the cutters in the forward gang to rise to pass over it. This movement depresses the cutters in the rear gang. When the first gang has passed the obstruction they will resume their normal position, and as the rear gang is raised in passing the obstruction the forward gang will be depressed.
A machine thus organized, it will be obvious, will thoroughly cultivate every portion of the field close up to any obstruction on each side of it. This operation of the machine is as follows: When the cutters on the front gang bar or crusher meet an obstruction they will be thrown up to ride over it, the connection d, with the frame, forming the fulcrum or pivot on which the gang vibrates. In thus rising they will force up the hinge-jointsj'f and depress the teeth in the rear gang, the fulcrum of the latter gang being at the joint h between the seat-supportingrods and cutter-bar. Vhen the front gang has passed the obstruction it will fall, and as the teeth iu the rear gang meet it they will be forced up. As the teeth in the rear gang rise they rock upon the pivot or fulcrum `h, and, forcing down the hingejoints ff, will press down the teeth in the front gang. Thus there is always a reciprocal compensating action or vibration between the gangs and a complete ilexibility7 which enables the machine to freely conform to the entire surface of the ground and act upon it in the most complete and perfect manner.
In the operation above described it has been assumed that thelever was held bythe notched dog in some adjusted position. The machine works to great advantage, however, when the dog is held out of engagement with the lever, so that it is free to vibrate in unison with the vibrations of the gangs. The flat portions of the teeth on the forward gang bar or crusher and the intermediate spurs or disintegrators forni a bearing for the machine and prevent the teeth from sinkingunduly into the ground. When the machine is thus working the frame, gang-bars, seat-support, and lever all vibrate, and the machine iieXes freely and conforms to all irregularities of the ground.
Should the machine at any time become clogged or encumbered with weeds or dbris of any kind, it can be freed therefrom by op erating the lever and vibrating or rocking the gangs.
The seat-standard and its pivoted supporting-bars serve as a pivoted coupling between the cutter-bar Gand frame in addition to and independent of their function as a seat-support, and I do not wish to limit myself to such a function.
So far as partof this invention is concerned, barrow-teeth may or may not be used on the front gang bar or Crusher; nor do I limit myself in the general organization of the machine as claimed to any special form of crusherbar. Where barrow teeth are used on the rear gang or cutter bar only they should be arranged in two reversely-curved series on opposite sides of the line of draft; or teeth so formed as to insure the rectilinear motion of the machine may be used.
In Figs. 3 and 4 disk cutters are shown as mounted ou the gang-bars. Such cutters may be used with advantage; but no claim is made herein to such organization. The disks are preferably placed at an angle both to thehorizon and the line of draft, as is well understood. The operation of a machine thus organized is similar to that above described.
Instead of having the seatstandard connected with the adjusting-lever, the link-connection may extend directly from the lever to the rear gangbar and the connection be so made as to give the results above set forth. In that case the pivot of the connecting-link on the gan g-bar would become the fulcrum on which that bar would vibrate.
I am aware that a harrow in which inclined vcrushing-surfaces are provided with rearwardly-projectingteeth is old 5 butthe teeth were ar- IOO IOS
