FURBOWIN'G DEVICE;

Application filed June 25, 1924. Serial No. 722,275.

' venient and positive control of the cutting depth is of the utmost importance, and wherein neither the surface of the earth to be plow-ed or a former furrow can be used as a basis for gauging the cutting depth thereof, and the main object is the construction of a combination by which the vertical position of the furrow-forming device can be indicated by means previously positioned abovevthe surface and parallel to the direction of travel. 7 l

The principal use of this device is in the forming of shallow furrows at each side of av roadway for the installation of forms which are generally placed in position at each side thereof, preparatory to the laying of what is known as concrete paving. In

the laying of a new road it is the practiceto first survey and indicate the grade of same by means of stakes properly positioned at each side thereof, the tops of which'indicate the desired level of the surface of the new road. A short distance inside each row of these stakes, and parallel therewith, is placed the before-mentioned forms: which are generally about nine inches high, and from the topsof which is gauged the entire surface of the intermediate roadway, both before and after the concreteis poured, and the importance of placing-these forms in the proper position relativeto the grade stakes will be readily appreciated, and it willalso be seen that for-the reason of thegenerally uneven surface of the road to be paved that it cannot be considered from the standpoint of a depth gauging foundation and that the furrow in which the forms are placed must necessarily be very carefully gauged from the suspended means on the grade stakes, namely, a gauge cord, and as it is quite frequently necessary to out these form furrows deeper than is practical with one operation, I desireto call attention to the po-- sitionof my plow relative to. thetractor,-

roller, or other propelling means which has a veryimportant relation to the practicabil ity of the combination, since by. positioning the plow entirely to one side of the propelling means and throwing the dirt outward, I' am enabled to make a plurality of operations in the same path without rolling. down the sides of, or disturbing the furrow with the roller wheels, in case this is necessary in order to gain the desired depth.

The usefulness and desirability of my device will be more readily appreciated when it is understood that this work is now done entirely by hand labor, which is always expensive, generally inefficient, and sometimes unavailable and inasmuch as rolling the sub-grade is always required by law, its

adaptability, secured to side of the roller as".

it is, to the work outlined. is very apparent and the factthat with'this combination-the form furrow, or groove, may be formed without interfering with the function, of rolling, adds greatly to' its value, in fact, itis my intention that the double duty ofcutting the furrow and rolling the subgrade alongside the same be accomplished simultaneously when desired. 1

By, a road roller let it be understood that I refer to a real road, rolling machine as shown, one rolling and compres-singthe soil over the total width of tread which means that my device may repeatedly traversethe same path, not only without damaging the. grade, but in case repeated passage is neces sary to gain the desired depth'of furrow, the grade will, on the contrary, be benefited thereby.

The main object of this invention is to construct an automotive combination for forming furrows at the side of a roadway, and the gauging thereof from a stationary means suspended above the ground.

Another object of this invention .is to construct a combination for forming furrows at the side of a roadway, wherein the cutting depth of the furrow-forming device is gauged bymeans entirely independent of the ground surface adjacent the furrow, a-nd' by this I mean there is no gaugewheel or other meansconnected to, or traveling} with, the plow by which its action is automatically influenced by the uneven surface.

It is also an object of this invention to provide a combination, wherein the furrowforming device can be quickly and. easily placed: ineith'er the operative or inoperative-- position, and can be carried on the roller when not in use without interfering, in any way, with the functions thereof.

It is a further object of this invention to construct a furrow-forming device having an adjustable depth indicator detachably secured thereto whereby the cutting depth of the device can be altered.

It is also an object of this invention to construct a furrow-forming device traveling entirely to one side of the path of the propelling means.

And finally, an object of this invention is the construction of an automotive combination for forming furrows at the side of a roadway, wherein the size and weight and steering of the automotive unit is used advantageously to govern the lateral movement of the furrow-forming device.

With the above, and various other objects and advantages in view, the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size,

proportion and minor details without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings,

Fig. 1 is a top plan of a furrowing device constructed according to the present invention.

Fig. 2 is a side elevation of same showing the side adjacent the gauge cord.

Fig. 3 is a rear elevation of a cross-section, taken on line A-A, of Fig. 2.

Fig. 4 is a fragmentary cross-sectional eievation of a portion of Fig. 3.

Referring to the drawings by numerals and wherein like parts are designated by similar numerals of reference throughout the several views, 10 designates a road roller, provided with a motor, transmission, carrying wheels and steering means of conventional type, the details of which need not be described here.

To the side of the roller at 11, and extending laterally therefrom, is secured, in. any suitable manner, the casting 12, which has secured therein an extension shaft 13, and on the outer end of which is secured a collar 14, which in turn is connected to the roller frame at 15 by means of the tension rod 16, in a manner maintaining relative rigidity between the shaft and the roller body 10.

Pivotally attached to the shaft 13 by means of the casting 17, is the draft beam 59 of the plow 18. By means of bolts,'19 and 20, there are attached to the plow beam, frame members, 21 and 22, which extend backward a sufficient distance beyond the plow to accommodate a supporting wheel 23,

said wheel being journaled in the forked casting 24 by means of the pin 25.

' Secured to the rear ends of' the frame members, 21 and 22, by means of bolts 26,

1s a supporting casting 27 which is proviced with a tubular vertical portion for the reception of the adjusting shaft 28.

Supported on, and secured to, the shaft 28 is a handwheel 29, for the manual rotation of same, and on the lower portion of shaft 29 is formed threads engaging similar threads in the tubular extension on casting 24.

Pivotally connected to casting 24, on each side of the supporting wheel 23 are two radius rods 30 and 30 which are also pivotally connected to the frame members 21 and 22, as shown at 31, and 31 Figures 2 and 3, the purpose of which is to positively connect the wheel to the plow, yet permit a limited amount of vertical adjust ment of the plow relative to the wheel.

Secured on the shaft 28, at ach end of the hollow chamber 32, in casting 27, are collars 33 and 34, the purpose of which is to retain the plow in its adjusted position when such position is altered by the rotation of the handwheel, 29, collar 34 holding it in its lowered position and collar 33 sustaining the weight of the plow when in the raised position relative to the supporting wheel 23.

Attached to the rear extended portion of 24, by means of bolt 35, is a downwardly bent plate 36 which serves as a station for the operator of the handwheel 29, and on which he rides.

37 is a cord suspended upon grade stakes 60, driven in the roadway, for the urpose, and secured to the side member 22, is a casting 38, by bolts 39, which has adjustably secured therein a crooked indicator rod40, held in its adjusted position by set screw 41.

45 is a seat for the operator of the roller and 46 is a steering wheel by which the operator is enabled to control the course of the front roller 47, by means of the rod 48, crank 49 and arm 50, arm 50 being positively connected to the yoke 51 in any suitable manner. The steering wheel 46 is con nected to the crank 49 in a workable manner, the mechanism details not. being a part of this invention.

Secured to casting 13, on the inner end of the tubular portion, and extending upward therefrom, is formed an arm 52 connected with which, in a pivotal manner, is a tension device consisting of rods 53 and 54, and a spring 55, said spring being flexibly connected at its ends with each of these rods.

Connected to rod 53, in a flexible manner, is rod 56 having, at its forward end, a hook 57, for attachment to the roller frame at 58 when it is desired to retain the plow in its raised position for transportation, or

. tic'al position by the operator by mean's'of the handwheel 29 and'threade'd rod 28, until the indicating means 40, previously ad'- justed and attached to the side thereof, indicates that the desired deptlrhas been obtained, and it is the business of the'plow operator to manipulate the before-men troned adjusting means and keep the plow andjcord in the desired relative position, while the operator of the roller, by virtue of its'stee'ring' mechaiiism', L6, 47, d9; and 50, with the assistance of the indicator l2, controls the lateral position relative to the cord, and therefore the plow. seen that in this manner an accurate flatbott'o'med' furrow or groove may be easily formed, and" by goihgi'n one direction on the right-hand side and" in the opposite direction'on the left-hand side, even though more than one operation be required to gain the desired depth, it can be easily and efliciently accomplished.

When it is desired to retain the plow in its inoperative position, its rear end is lifted until itis possible to engage the hook 57 in rod 56 with the hole, 58, at the side of the roller frame, the spring 55 assisting in this operation, the plow beam 59 now assuming the position shown at 59 (in dotted lines) and the position of the spring arm 52 changed to 52 and the spring 55 contracted.

Obviously, by virtue of the rigid pivot formed by 12, 13, 1e and 16, the slightest lateral movement of the roller 10 will affect the plow, the operator of the plow controls its vertical movements only, and the operator of the roller controls its horizontal movements only. This point is well worth consideration, since only by concentrating on the control of one movement each is itbelieved possible to accomplish the result obtained.
