To all whom t may concern:

Be itknown that I, ANDREW P. ANDERSON,

a citizen of the United States of America, ref.

siding at Stoughton, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Harrows, of which the following is a specification, reference beinghad therein to the'accom pany'- ing drawings.

This invention relates to certain new and useful improvements in harrows, and relates more particularly to that class generally known as wheel-harrows or sulky-harrows.

The invention has for one object to con struct a harrow of this type with a series of vibratory or longitudinally-oscillating dragbars arranged in two sets, with one of Said sets actuated through gearing connected to the one drive-wheel and the other of said sets actuated through like gearing connected with the opposite drivewheel.

Another object of the invention is to construct a barrow of this type in which each drag-bar will be independent of the other dragbars for elevation to pass an obstruction or the like, together with means whereby all the drag-bars of each set may be simultaneously elevated to the inoperative position or lowered to their working position, which opera tion may be controlled by the driver from his seat by the movement of a single lever.

A still further object of the invention is to provide means for operating both gears from a sin gle lever within easy reach of the driversl seat and to provide-a frame of rigid construction which may, if desired, be constructedy from ordinary angle-iron.

The invention further consists in the novel construction, combination, and arrangement ot' parts, as will be hereinafter more specifically described and then particularly pointed out in the claims.

Briey described,the elements entering into the combination in my improved har-row are a frame of especia-l construction, the axles for the drive-wheels, journaled in said frame, the drive-wheels mounted on. said axles, the two trains of gearing, and the series of drag-bars, these latter vdivided into two sets, one set for each train ot' gearing. These drag-bars have a vibrating or oscillatory movement when in the working position during the travel of the barrow and are pivotally supported at their forward ends in such a manner that when one of the bars engages a stone or like obstruction the other bars will not be affected thereby; but the bar alone that engages the obstruc- 1'tion will elevate, so as to clear such obstruction. VAt their rear ends these drag-bars are swiveled from a cross-rod in such a manner as to permit their vibratory movement and also the independent elevating or lowering of v one bar with respect to t-he remainder. An elevating and lowering frame for the drag-bars is carried by the truck-carriage frame and is operated by a lever located adjacent to the drivers seat, while by means ot' a separate lever, also located adjacent to the driveris seat, the clutches controlling the two trains of gearing are thrown into or out of operative relation. All of this construction, together with the minor details, will now be described specifically, v ence will be had to the accompanying drawings, forming a part of this specification, and

employed for designating like parts through out the several views of the drawings, in

Which- Figure lis a top plan View of my improved harrow, showing the relative position of the two cranks which operate the vibratory or and in such description, refer# wherein like numerals of reference will beoscillating draglbars. Fig. 2 is a longitudinal f sectional view ofthe harrofw, taken on the line 2 2 of Fig. l. Fig. 3 is a rear view showing the drag-bars in the operative or working position. Fig. 4 is a detail sectional view of a part of one of the drag-bars, the vertical arm to which the drag-bars are pivotally connected at their rear ends, and of the horizon tal arm which connects the drag-bars with the operating-cranks. Fig. 5 is adetail perspective view of a part of the truck-carriage frame, the pivoted elevating and lowering frame for the drag-bar, and also showing one of the drag-bars and its connection with the operating-crank. Fig. 6 is a detail perspective view of one of the sleeves which form the swivel or toggle-joint connection fory the rear end of each drag-bar.

IV will tirst refer to the construction of the frame,which of the form herein shown is light, yet serviceable and durable. This frame consists of the side rails 1, which in the form herein shown are constructed of ordinary angle iron or steel and are connected at their front ends bya cross-brace 2, likewise of angle iron or steel with the ends bent inward and bolted, riveted, or otherwise rigidly secured to the side rails 1. Arranged outside of these side rails 1 is a pair of auxiliary side rails 3 of shorter length than the side rails 1 and composed of angle iron or steel, with their ends 3 bent inwardly and rigidly secured to the side rails 1. A flat cross-brace 4 extends underneath the side rails 1, near the forward ends thereof, and has its ends rigidly secured to the outer faces ofthe auxiliary side rails 3, near the forward ends thereof. A similar fiat cross-brace 5 extends underneath the side rails 1, near the rear ends thereof, and has its ends rigidly secured to said side rails 1. Centrally supported on these two cross-braces 4 and 5 is a beam 6, a convenient form for which I have found to be the ordinary channel-bar, which beam, together with the side rails 1, forms supports for the bearings in which the operating-cranks of the drag-bars are journaled. 'Mounted upon the side rails 1 and the auxiliary side rails 3 are bearings 7 7, in which are journaled the axles 8 8, having the drivewheels 9 mounted thereon. The hub of each of these drive-wheels is provided with a rigid clutch-section 10, adapted to be engaged by the movable clutch 11, slidably mounted on the axles 8.

.Iournaled in bearings 12 12 on the side rails 1 and auxiliary side rails 3 and in a bearing 14, mounted upon the beam 6, are the operating-cranks 15 and 16 for the drag-bars, the one crank being driven from 011e drivewheel and the other crank from the opposite drive-wheel. These cranks are driven by gears 17, mounted upon the axles 8, which mesh with gears or pinions 1S, mounted upon the cranks 15 and 16, respectively. The rods or shafts composing the cranks have their crank portions alternating in position, so that when one drag-bar is at the forward limit-of its movement the adjacent drag-bar on each side thereof will be at the limit of its rearward movement. By providing two of these operating-cranks with a separate gearing for each crank two sets of drag-bars are formed, one driven by one crank and the other set by the other crank. The drag-bars 19 are provided with aseries of teeth 20, arranged'therein in two rows, or, in other words, in zigzag position-that is, each alternate tooth being placed in the drag-bar adjacent to the opposite side from that ot' the preceding tooth. These drag-bars are preferably provided on their forward ends with a strap 2l, which is doubled and secured to the upper and lower faces of the drag-bar, the loop thus formed beyond the forward end of and projecting or in a vertical position the bar acting as a buffer for the bar in' event of its engaginga stone or like obstruction in the soil. The drag-bars are supported at their forward ends by a chain or link connection 22 with a cross-bar 23, having its ends pivotally connected to a yoke 24, which forms a part of the frame for elevating and lowering the drag-bars and is pivotally supported at its ends from the side rails l of the main frame. At their rear ends these dragbarshave an eye 25 secured therein, to which is pivotally attached an arm or rod 26, capable of both a vibrating movement, as required by the drag-bar in its operation, and of a vertical movement to permit the independent movement upwardly of each drag-bar when required. To support these drag-bars at the rear end thereof and also to simultaneously elevate and lower the same when desired, I pivotally attach to the side rails 1, near their rear ends, a yoke 27, in the an gularl y-extend ing ends 28 of which is mounted a cross-shaft 29. Upon this shaft 29 is mounted a series of double sleeves, consisting of two members 30 and 3l, the former extending horizontally and receiving therein the shaft 29 and the latter extending transversely' to the former to receive the rods or arms 26, which are pivotally connected at their lower ends to the rear ends of the dragbars. These rods or arms 26 are bifurcated at their upper ends to receive stems 32, secured therein, preferably by both a metal rivet or screw and a wooden pin 3i. This construction is provided so that in the event of a sudden blow being delivered against any one of the dragbars the plug or pin 34, being the weaker part,will naturally break first, and the rigidity of thejoint between the rod 26 and stem 32 being thus broken no further damage will be done to the parts. These stems in their part projecting above the rods or arms 26 are likewise bifurcated to receive the end of a n1etallic bar 35, which is pivotally attached by a rivet to said stem and has its under edge cut away, as at 3b', so as to permit the full sweep as requiredby the drag-bar in its movement. This bar is securely fastened in the rear ends of the crank-arms 37, one of which is provided for each drag-bar and which connect at their other ends with the cranks l5 and 16, respectively. iVhen these cran k-arms are construct ed of wood, I may attach them to the cranks by cutting out a part of the forward ends, as shown at 38, placing the cranks in this end of the arm, and then securing the part 38 in its position by bolts 39. Likewise when these arms are constructed of wood in order to prevent the splitting of the same I preferably slit the rear ends of the same, insert the bars 35 therein, and secure the same by rivets 40, placing within the crank-arms at the termination ot' the slit for the reception of the bar 35 a pin or rivet 41, against which the inner end of the said bar may seat itself.

For the purpose of simultaneously elevat- IOO IIO

ing and lowering the 'drag-bars, I attach to the yokes 24 and 27 centrally thereof, a yokelever 42 and pivotally connect to the side of the beam 6 a lever 43, which is connected by a link or strap 44 to the yoke-lever 42, so that when the said lever is moved backward it simultaneously operates and moves downwardly the yokes 24 27, elevating the anglilar ends thereof, and consequently elevating at the same time the cross-bar 23 and rod or shaft 29 and carrying the drag-bars upward therewith.

In order to engage both ltrains of gearing at the same time, and thus cause the simultaneous operation of both sets of drag-bars, I provide two singularly-shaped levers 45 and 46, each having forked ends to engage the respective clutches 11 on the driveaxles. These twoclutch-operatinglevers are each provided with oblong slots 47 to receive headed pins 48 at the front ends of the side bars 1, the lever 45 having its end pivotally attached to one end of a link 49 and the lever 46 having its end similarly attached near the opposite end of said link, the link being in turn pivotally supported upon a saddle 50, attached to the crosslbrace 2 and beam 6, so that when said link is actuated the ends of the levers 45 46, attached thereto, will be simultaneously moved toward or away from each other, according to the direction in which the link is moved, and the clutches 11 consequently be simultaneously engaged with or disengaged from the clutch-sections carried by the hubs of the drive-wheels. The inner end of this pivoted link 49 is bent upwardly and provided with a notch 51 to receive the end of the operating-lever 53, pivotally supported on the saddle 50, said lever being held so as to retain the clutches in engagement or in the inoperative position by the rack-bar 54, mounted upon the saddle 50. A seat 52 may be suitably supportedeither from the cross-brace 4 or from the beam 6, and a foot-rest 55 may be attached to the saddle 50 or at any point desired. The saddle 50 may, if desired, be extended, as shown, beyond the front crossbar for attaching the draft-equalizer thereto, and the tongue 56 may be connected to the front cross-bar in any desirable or suitable manner.

I will now briefly describe the operation, assuming the parts to bc assembled as shown in Fig. 1 of the drawings, and the lever-53 being in the position shown in this view, so as to cause the engagement of the clutches. Upon the forward movement of the harrow the gears or piuions 17 18 cause the independent rotation of the crank-rods 15 16, operating the crank-arms 37 and imparting a vibratory movement to the rods or arms 26 to cause the oscillation of the drag-bars 19. The cranks of these crank-rods being set alternately or at the half, it will be observed that each alternate drag-bar of each set is at the forward limit of its stroke when the remaining drag-bars of each set are at the limit of their rear stroke, and upon the engagement of any one of the bars with an obstruction the links forming the connection 22 between the forward end of the bar and the bar 23 will by their collapsing or doubling upon each other permit the elevating of this bar independently ot' all-the other bars,- so that the operation of the remaining drag-bars will not be interfered with, and by reason of the rods or arms 26 sliding vertically within their sleeves 31 the elevation of the bars at their rear ends will be permitted, as well as at the front end, so that such obstructed bar may pass readily over its obstruction.

When moving the harrow from one field to another or at other times when it is not desired for the vdrag-bars to operate, the lever 53 is thrown so as to disengage the clutches, the lever 43 thrown backward, and the dragbars elevated to a position underneath the main frame of the harrow.

While I have herein shown and also described the various elements in detail and also the manner of assembling the same, it will of course be evident that in the construction of the harrow various changes may be made in the details thereof without departing from the general spirit of my invention.
