ROAD WORKING MACHINE Edward Scheunemann, Mount Clemens, Mich. Application December C, 1937, Serial No. 178,322

9 Claims (ohm-160) I i chine mounted on an axle intermediate the ends thereof, the axle having a bend near each spindle thereof whereby it may be rotated to lower and to elevate the framethereof, the lower position being its working .position and its upper position being its carrying or transport position.

Another object is to provide a multiplicity of possible positions which the frame may assume with respect to the roadway in order to accommodate itself to various types of work, these positions being affected by the provision of multiple rotative adjustment of the axle with respect to said frame.

A further object is to provide a draw member pivotally attached to the frame in order that the cutters may freely' jdrag along the ground in combination with means for rigidifying this member with respect to the frame when in carrying position. A specific object is to provide a multiplicity of positions in which the rigidifying means may function whereby the frame may be made to travel horizontally regardless of whether the vehicle by which it is to be transported is relatively high or low.

Another object is to provide blade holders and blades therefor of such construction that they may be shifted longitudinally'of their holders in order to alter their positions with respect to the frame side rails thereby lendingthemselves to use for scraping or for shoulder forming.

Another object is 'to provide .means for adjusting at least one of these blade holders'longitudinally of at least one frame. side rail whereby it may be given the most advantageous position for the type of work. to be performed."

A still further object is to provide a detachable trailer blade holder and blade universally connected near .therear end of one of the frame This trailer blade has the function pleting the shoulder forming operation.

Another object is to provide an improved blade having two cutting edges, one of the edges being straight, the other being serrated in order to more readily cut into hard roads such as oil hardened earth roads. The straight edge may then be used for planing. 7

respectively.

. More particularly l indicates a frame having right and leftside rails 2 and 3. Secured beneath the side rails. bythe bolts '4 are blade holders 5, 6 and 1 arranged respectively nonparallel. The blades 8 and 9 are respectively attached to the holders 5 and 1, the holder 6 being equipped with two blade sections Ill and II.

. Journ'alled in the side rails 2 and 3 is an axle l2 bent "at 13.near each end and terminating in spindles upon which the wheels I4 are rotatably mounted.

Theframe with itscutter blades is balanced on its journals in such manner that it is slightly heavy toward the front end thereof. Intermediatetheside rails Z and 3 two wheels I 5 are fixedly secured to the axle [2; These wheels are serrated at IE to provide a plurality of gear teeth for a plunger ll spring pressed at I 8 and slidably mounted in an arm l9 J'ournalled on the axle l2 between the wheels IS. The plunger IT, by falling into a space between two teeth l6, rigidities thearm l9 with .respect to the axle so that upon rotation thereof v the axle may be caused to rotate-tpusswinging thearm [3. It

may thus be seen in Fig. 2 that if the axle I2 is rotated clockwise the frame I will be elevated whereas rotation of the axle in a counterclockwise direction will cause the depression of the frame l toward the ground until contact is established between the ground and the blades 8, 9, EB and H.

A draw member 2! the front end 21 of which is adapted for attachment to'a truck, a tractor or other prime mover is pivotally connected at 22 to the side rails 2 and 3 so that the frame with its cutters may be dragged along the ground. In order to transport the frame upon elevation thereof by consequence of the rotation of the axle I2 as previously described, the draw member 20 may be rigidified with respect to the side rails 2 and 3 by the insertion of pins 23 through an opening in each rail of the members 20 which align with any one of a plurality of vertically spaced holes '24 in a bracket 25 arising from the front end of the side rails 2 and 3 at their points of attachment to the cross rail M. This adjustment permits an angularity between the drawbar and the frame rails in order that the frame may be maintainedhorizontal while being transported regardless of variations in'height of the vehicle to which it is attached. Arising from the cross member 26 is a rack 25 having a multiplioity of fingers 2? extending outwardly therefrom in vertically spaced relation to serve as means for retaining the arm is in any given position. Thus, with the plunger I! in engagement in the manner illustrated in Fig, 2 .the arm may be made to engage any one of a number of the fingers 21 to adjust the height of the frame I with respect to the ground, the selection of position being variable by a small amount in order to accommodate the blades to the particular type of work for which they are called upon.

Fig. 3 shows the arm [9 being swung to vertical'position in which event the wheels [4 are elevated entireiy from the ground and consequently add their weight to the weight of the frame. By moving the finger H from the position shown in Fig. 3 to the last notch Ifia in the wheel I5 the arm l9 may be made to engage a finger 2! thus retaining the wheels in the position illustrated. Ifthe finger ll be moved to the other end of the notch portion into engagement with the notch itb the arm I9 may be made to engage one of the fingers 27 and retain the-frame in transport position. Between these two positions numerous adjustments are advantageous depending on the type of work to be done.

Fig. 1 illustrates the machine with the various blades so arranged that the machine is adapted for use as a scraper or planer. The front blade 8 terminates well inside the left side rail 3, the blade Hi extends Well outwardly of the side rail 3 and the blade 9 also extends outwardly of the frame rail 3 but to a less extent than the blade is. This is the conventional arrangement of lades for this type work. In order to convert the machine into a shoulder forming machine the blade 8 is moved longitudinally of its blade holder for an amount such that it terminates immediately below the inside edge of the left side rails 3, the blade H] is removed leaving only the blade H on the inside blade holder Sand the blade 9 is moved to a position beneath the center of the left side rail 3. The blade holder 1 is shifted in position so that it will assume the position illustrated in dotted line la, the posi- Fig. 14. This requires that the bolts 4 which attach the holder 1 to the rail 2 be removed and that two of them be replaced for engagement with the holes 4a and that the bolts 4 in the member 3 be removed and that two of them be replaced to pass through the holes 4b. Due to the change in angularity of the member '1 with respect to the side rails only two of the bolts will be replaced at each side rail.

In order to permit the shifting of the blade 8 with respect to the holder 5 the blade is secured to the holder by bolts 28 uniformly spaced so that the blade may be shifted a distance equal to one, or a plurality of links between both holes. Thus, I have illustrated three different means in the three different instances for changing the position of the'left hand end of the blade with respect to the side rails 3. Obviously all blades might be shifted according to the plan in either one of the three diiferent ways illustrated.

The illustration of the blades in their two positions of planing and of shoulder formation is illustrated in Figs. 13 and 14 wherein it is seen that the object of the front planar blade is to scrape the road surface and also to move a portion of the dirt laterally to the left, where it is taken by the intermediate blade and moved transversely of the road, this blade dumping a residue onto the final blade 9, this final blade being slightly elevated with respect to the other two blades by virtue of the fact that the frame normally tilts forward. In Fig. 14 the arrangement shows the front blade in position for planing with the residue being dumped at the edge of a hard surfaced road 29, the intermediate blade acting as a scraper for delivering a quantity of earth to the rear blade 9 which is now turned at such an angle that it accepts all the earth delivered by the blade II and transports a certain quantity of it over to the shoulder of the road 29 and actually upon the road 29. In this manner, the operator may be certain that the shoulders immediately adjacent the road 29 are completely built and it remains thereafter to scrape or sweep the road 29 of dirt which has been dumped thereon by the blades 9. In order to accomplish this, I provide a rear trailer blade holder 36 having a blade 3| secured thereto, this blade normally travelling at an angle such that it scrapes any dirt on the road 29 off the side thereof in the direction of the newly formed shoulder. This holder 30 is attached to the left side rail 3 by means of a pin 32 which fits in a slot 33 with sufficient play or looseness to permit a substantial universal motion between the holder and the side rail 3. The holder 30 is thus readily detachable from the side rails 3 or it may be rotated about its pivot 32 through an angle of substantially to a carrying position as illustrated in Figs. 1, 2 and 3.

The blades 8, 9, H], H and 3| are each constructed with two cutting edges, one of the edges being straight whereas the other one is serrated as indicated at St. The straight surfaces are employed for ordinary planing or scraping work whereas the serrated edges are employed, for instance, on earthen roads hardenedby oil applications and having many holes therein. By pulling the machine over these holes with the serrated teeth for one or several times the earth is sufiiciently loosened at its surface that when the blades are reversed and the machine then pulled thereover, a smooth surface results.

Various modifications maybe made without tion being illustrated in full lines on the diagram departing from the spirit of my invention and 7 arm to said axle for the rotation thereof through a substantial angle whereby said-frame may be lowered into road working positionor elevated to carrying position, said means being adjustable to vary the relationship between the arm and the cranks, and a rack bracket having a plurality of vertically spaced fingers each one of which is adapted toreceive and to retain said arm.
