ROAD-FORMING MACHINE.

Application filed July 12, 1919.

To all whom it may concern Be it known that I, Bron R. BoNNnY, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Road-Forming Machines, of which the following is av specification.

This invention relates to a road-forming machine of the class used in forming ditches at the sides of the road and moving the ground toward the middle of the roac. from the ditches, and forming a road surface convexed in cross-section. The invention has for its object, broadly, to provide such a construction that a limited power, compara tively, will be required for moving the ground surface, and includes certain fea tures relating to convenience in control and operation, and certain adjustable features found to he of advantage, all as hereinafter fully described and claimed, and as illustrated in the accompanying drawing, wherein.

Figure 1 is a plan view of a road-forming machine embodying the invention. Fig. 3 1s a view showing the end and rear part of the machine, said view being taken parallel with v the opeflting shaft and longitudinal axis of the traction wheel. Fig. 3 is a broken away detail showing an end view of a pair of connected scraper-blades. Figs. 4b and 5 illustrate journaled bearings of the axle in a part of the oscillating machine frame, Fig. 4 showing the axle in transverse section, and Fig. 5 showing the frame in section. Fig. (5 is an enlarged detail, partlyin section, relating to Fig. 1 to clearly show the use of a universal joint in connection with the mounting, on the axle, of a pair of bladearms, the axle being in section. Fig. '7 is a plan view of the parts shown in Fig. 6. Figs. 8 and 9 are enlarged details, partly broken away, illustrating means for the control of the movements of the oscillating frame. Fig. 8 shows the position of parts for maintaining the oscillatingframe in a. horizontal position. Fig. 9 shows the posi tion of parts when the front of the oscillating frame has been swung downwardly for elevating the blades, to permit dumping.

Referring now to the drawing for a more particular description, 1 provide a frame 1 of elongated form, adapted to have a swinging movement forwardly and rearwardly Specification of Letters Patent.

Serial No. 310,391.

from a non-revoluble axle 2, said axle being provided with an inclined part (4 out 'ardly of one end of the frame for a mounting thereon of a traction wheel 3. Numeral it: indicates a raster wheel, its pintle Z) being disposed midway between the front and rear parts of the frame 1, adjacent to that end of said frame opposite to the wheel 3. Numerals indicate cross-pieces for reinforcing the frame thus described.

I provide an over-frame consisting of a tongue 6 disposed substantially at rightangles to the inclined part a of the axle, said tongue, as best shown in Fig. 1, extending rearwardly to overhang the axle and a part of the frame 1, for use in mounting rts thereon, said memcertain operating her 6 being provided with a brace, preferably of V-shape, its arms 0 and (Z being rigidly mounted upon the axl the front end of the tongue having a vertical part c I provided with apertures for use w ien connecting the device with a tractor or similar object for moving the device forwardly.

By referring to Fig. 1 it will be seen that the connections for the front ends of the brace-arms c and (Z with the tongue are adjacent to the front end of tie latter, and

since the rear ends of said arms and the.

ton ue are rigidly mounted upon the axle the frame 1 may have a limited swinging movement relative to the overframe, the frame 1 and members 5 having journaled bearings upon the axle. Numeral 7 indicates a link or bar suitably connected with the axle outwardly of the frame 1, for the support of a platform 8.

At 9 are indicated a plurality of trans versely curved blades, and at 10 is indicated a comparatively short blade which is also transversely curved, and for convenience, is identified as a ditch-blade, these being disposed approximately in line, rearwardly of the frame 1, the o end of each blade 9 being disposed rearwardly of the near end of a blade adjacent thereto, each blade 9 and the blade 10 being provided with a pair of convergently disposed tongue-arms 11, the L-shaped bar 12 6, 7,) which connects each pair of arms 11, at their junction, being received by a swivel member 13 which is mounted in a clevis 14, the latter being rigidly mounted upon the axle; and it will be understood that, on account of this construction, both longitudinal and transloosened soil to be conducted toward the middle of the road bed, means to be employed, and to be described, under control of a: driver or operator, for changing the inclination, longitudinally, of the blade 10, so that it will form a ditch. indicates a cutter-disk disposed forwardly of the outer end of the blade 10 for cutting the ground or sod in the formation of a gutter or ditch, said disk having a frame or tongue 16 ofvs'ufiicient weight to cause the disk to suitably enter the ground, said tongue being pivotally connected with the frame 1, as best shown in Fig. 2.

In order that the blades 9 may be adjusted as to height to form a road bed having a convexed surface in cross-section, pull-rods 1? are employed for a connection with certain bell-cranks 18, the latter being mounted upon the rear part of the frame 1, and any suitable connection may be made of the bellcranks 18 with said blades 9, said connection in the present instance being chains 19, the lower ends of each chain being mounted upon a coupling-pin 20 which connects the adjacent ends of said blades as best shown in Fig. 3; and by means of hand-levers 21 and the conventional toothed sectors which are mounted upon the platform 8, an operator may elevate or lower said blades 9 for engaging the ground to form the required curvature of a road bed.

The blade 10 may also be elevated or lowered by similar means to that last described,

toothed sectors 22 being mounted upon the platform 8 and used in connection with hand-levers 23, rigid pull-and-push rods 2e being employed and connected with bellcranks 18, and rigid links 25 and 25f also being employed and connected with said bell-cranks, the link 25 being connected with the outer end of the blade 10, and the link 25 being connected with that end of the blade 9 adjacent to said blade 10, whereby the outer end of said blace 10 may be elevated or lowered independently of its inner end, said inner end of the blade 10 being pivotally connected, as indicated at h with said blade 9, the advantage to be derived by this construction being that an operator, by use of hand-levers 23, may conveniently Numeral 15 maintain the blade 10 with its outer end somewhat lower than the other blades, to form a ditch, the end of the blade adjacent thereto being under similar control by means of the link 25 to cause it to be lowered for the formation of the ditch, in con- V junction with the curved surface of the road bed.

It will be appreciated that the stresses directed to the frame and axle occasioned,

during operation, by the resistance of the' vwill contain or hold. these acctunulations,

and-therefore an upward movement of the blades for dumping, may require considerable force, and that if levers alone were depended upon for this purpose, operation would be attended with some difficulty; and therefore I provide means, movable by the wheel 3, for causing a swinging movement upon the axle of the frame 1, for elevating the blades, said means being best shown in Figs. 8 and 9. I 4 i Numeral 26 indicates an operating-shaft in suitable bearings, said shaft being disposed approximately at right-angles to the tongue 6 and parallel with the extension (4 of the axle 2, one of its ends having a drum 70 mounted thereon as an idler, its opposite end being provided with a sprocket wheel on, said shaft being revoluble by means 'of a sprocketch ain m in engagement with a sprocket-wheel n which is provided for the wheel 3.

In order that the drum may be rotated whenever desired, a conventional clutch r is splined upon theshaft 26, and may be moved into engagement with the drum by means of the arm 8 of a bell-crank 27 which ismounted upon a bracket 28, the latter being secured to the tongue 6, said bellcrank 27 being movable by means of'a pulland-push rod 29, under control of a hand lever 30 which, as best shown in Figs. 8 and 9, is provided with a toothed sector a? and, in part, is controlled by a spring as and by a conventional pawl, as shown.

The lever 30 is also provided with a rod 31 adapted to control the movements of a pawl-member 32, the latter being slidably mounted upon the flange 33 of the tongue.

Mineral 34: indicates an operating-bar disposed parallel with and having a pivotal mounting for one of its ends upon the tongue, its opposite end being provided with a pulley 35. At 36 is indicated a spacingbar, its upper endbeing pivotally mounted upon the bar 34 between the ends thereof, its lower end being pivotally mounted upon a bracket 37 which is disposed below the tongue and is secured upon the front part of the frame 1. Mounted upon the tongue is a second pulley 38, and at 39 is indicated a cable having its respective ends secured to the drum and to the tongue, said cable being in engagement with the pulleys 35 and 38.

The bar 36 is provided with notches or recesses t and e, and the normal position of parts are as shown in Figs. 2 and 8, the operating-bar projecting above the tongue, the clutch 0* being disengaged from the drum and the fame 1 being disposed in a horizontal position, the parts being held in the positions mentioned on account of engagement of the pawl-member 32 within the recess '2; of the bar 36.

When the operation of dumping is required, the operator, while the machine is moving forwardly, causes the lever 30 to swing forwardly, which causes a swinging movement of the bell-crank2'i' for moving the clutch 1" into engagement with the drum to cause a rotation thereof, said forward swinging movement of the lever 30 also causing the pawl 32 to be withdrawn from the recess '0 to permit the levers 34 and 36 to move downwardly.

The downward movement of levers 34 and 36 operate to cause the front part of the frame 1 to swing downwardly, the rear part of said frame 1, together with the blades 9 and 10 being elevated, the elevation of said blades operating to release the accumulations of earth held by said blades.

Since the machine is moving forwardly during the operation last described, the release of the accumulated earth from the blades will be gradual, and will be spread to advantage uniformly upon the surface of the road-bed.

Numeral 40 (Figs. 8, 9,) indicates a ball or detent which is secured to the cable 39, and when said cable is wound upon the drum by the means described, said detent will engage the arm '20 of the bell-crank 27 and will cause it to swing, its swinging movement causing a movement of the clutch, and causing a release of said clutch from the drum, so that a further revoluble movement of the drum will be prevented; and the parts are so arranged and proportioned that the pawl 32 will enter the recess 2? as soon as the clutch is moved by the bellcrank 27, tnis being when the revoluble movement of the drum ceases.

Since the blades 9 and 10, during the forward movement of the machine will be disposed at an angle to the line of travel, the loosened earth will be moved, to a greater or lesser extent, toward the medial line of the road-bed, and weeds, grass, chunks of arth and trash will be conducted readily in the same direction. and therefore a spreading device is provided consisting of a rakemcmber 40, preferably having curved tines .2 mounted in an arm ll, said arm being pivotally mounted, as indicated at 42, upon the outer end of a blade 9 to be disposed outwardly and rearwardly of the traction wheel 3 and substantially parallel with the axle-extension a, a holder 13 being provided and connected with the axle-extension a and the outer end of said arm, the function to be discharged by said member 40 being to cause the material mentioned to become spread upon the surface of the road-bed.

hile I have described construction in detail, it will be understood that changes may be made in form, size, proportion and minor details, as may be found to be of advantage, said changes to be determined by the scope of the invention, as claimed.
