"To all whom it may concern Be it known." that I "JOHN H. Molunon,

QJIISELS; have invented certain "new My 'inven'tion is an improvement in road "machines; and has for itsobject to'provide a machine of the character specified which will "work' the road "whether wet or dry,

water out of the ruts and packing the soil from the high places to the lowplaceswhen wet, and afterward finishing an'df smooth ng the road, wherein thecrushinga'nd packing is bro-ught about 'bya' roller having a spiral "or spiral ribs which-works the soil as it moves thereover.

-In the drawings: y

fFig. 7 is a vertical-section throughone of the hearings of the'finishing roller;

Fig. "8 is a "front view of the "packing T roller, with' thel'frame' insec'tion S r"'viewofranother"form "of packing i roller.

l thepresent emodiment of the invention a=fsuitablefranie lis 'provided', 'which*is sup- 2 and at 1 its front end' by -a pair 0f." front wheels' 3. These'wheelsii are. journaled 'on spindles 4; "on the ends *of' an aXle- 5,'-which is yieldingly connected with the frame, and

Y the spindles are "hinged" to 1 the ends of the "axle, and are connected tomove togetherby means of a link 6' which is I pivoted at its tends" to arms '7 extending rearwardly' from Y the spindles.

-A plate 8"issecured-t'0'the top of the-axle, andit-will be'noticed that-'this axle is of hol'low construction, 'loeing -square inthe prese'nt instance, and the ends of the plate "8are-oiiset upwardly, as indicated at 9.

Eaclr'of the said endsis slidably connected byva rod 10 with the frame l, -and"a 'coil fspringll is arranged between the framef'and each tot the "upwardly offset "ends"' 9, the

" spring a 'cting normally to jpress the frame upwardly. Themed l0"being, however ;isl id- -.ably connected with the" oiiset end 9' of' the plate may move downwardly with "respect thereto, thus providing a spring support for the frame.

' The rollerQhas journalfp'ins l2iat itscnds,

rand these ,pins are journaled in J sectional hearings on the undersides ofjplates' l3.

Eachof these plates has upwardly'fci'irved portion. 14 at its rear end, which is pivoted to the frame 1 as indicated at 15 at the rear end of theframe. At'their forward-ends the plates 13 have openings through which extend pins16dependingkfrom the frame 1, and a coil spring 17 encircles each pin between the plate'13 and the frame, acting normally to press the plate downward. "Thusxa yielding mounting is provided for'the' roller 2. Thisiroller is driven topropel themarun ofeach' chain 18 is tensionediby an idler 23 whichis arran 'ed'on a braceplateQ/L extending longitudinally ofthe frame. T he machine is steered by: Ineansfot a steering column '24 which is suitably supported by the frame, the-said column'havin'g'at its lower end a'worln 25 which meshes "with a Worm wheel 26 journaled on an auxiliary frame" 97 which connects the front axle with a cross bar 28'of the frame. This-wheel26 is connected by a 1ink'29 with the-arms 7 of one of the spindles, and *it will be" obvious that'when the wheel 26 is rotated by means of the steering column the wheels" 3 will be swung to guide the frame.

The packing roller 30' is arranged-in front of the finishing roller, the-"said packing roller having a shaft 31 whose ends are journaled in the rear ends of the plates 32 whose forward ends are pivoted to the frame 1, as indicated at 33. Rods 34 are connected with the ends of the shaft 31, each of the rods having an eye engaging the shaft, and these rods extend upwardly through the frame 1 and are engaged by wheeled nuts 35 above the frame. Thus by means of the wheelel nuts the shaft 31 may be raised or lowered to raise or lower the packing roller with respect to the frame, that is, to regulate the pressure of the packing roller on the soil.

The roller 30 may have a single spiral rib 36 as shown in Fig. 8, the said rib being continuous from one end to the other, or the roller 37, as shown in Fig. 9, may have a spiral rib 38 at each end, the said ribs being symmetrical and acting to force the soil outwardly in both directions from the center of the roller. Either form of roller may be used, the rollers .being interchangeable.

Guide brackets 39 depend from the frame 1 'fadj'acent to each plate 32, to guide the vertical movement of the said plates during adjustment.

As shown in Fig. 7, the journal pins 12 are journaled in sectional bearings 40 011 the plates 13, the sections of the bearings being secured to each other and to the plates by bolts and nuts 41. The journal pins are arranged within a bushing 42 and a ball bearing 43 is arranged within the bushing between the shaft and the bushing.

v The upper section of the bearing and the plate have registering openings forming an oil passage, and an oil cup 44 is connected with the opening for lubricating the bearing. It will be noticed, referring to Fig. 7,

that the bushing has an opening registering with those of the plate and the upper bearing section.

Means is provided for scraping accumulations of soil off the peripheral surface of the finishing roller. The said means comprises a scraper blade 45 which is secured to a-shaft 46 journaled in the frame 1 in rear 1 of the'roller 2. Rods 47' are connected with the opposite ends of the scraper blade, and these rods pass forwardly and upwardly atan incline through bearing plates 48 on the frame. Wheel nuts 49 engage the rods above the bearing plate, and it will be evident that by turning the wheel nuts in the I proper direction the scraper blade may be moved toward or from the finishing roller .to scrape accumulations therefrom.

The machine is the wheel on the steering post 24. The

,packingroller 30 moving over the road surfacepacks the soil or road material, movlng it from the high places and filling up the low places. If the soil is muddy it is worked just the same, the water being squeezed out and permitted to drain away. Afterward, the finishing roller 2 comes into play, thoroughly smoothing and packing the soil or road material to present a finished surface.

The finishing roller is provided with a hood 50 which covers the top of the same, the hood being secured to the main frame.

I claim:

1. A machine of the character specified comprising a main frame, front wheels for supporting the front end of the frame and arranged to swing to guide the frame, a finishing. roller journaled transversely of the frame at the rear thereof, means for driving said roller to propel the frame, and

finishing roller journaled transversely of the frame at the rear thereof, means for driving said roller to propel the frame, and a packing roller journaled transversely of the frame in front of the finishing roller and vertically adjustable, independently of the finishing roller.

3. A machine of the character specified comprising a main frame, front wheels for supporting the front end of the frame and arranged to swingto guide the frame, a finishing roller journaled transversely of the frame at the rear thereof, means for driving said roller to propel the frame, a packing roller journaled transversely of the frame in front of the finishing roller and vertically adjustable, plates pivoted to the frame at the rear corners thereof and extending forwardly below the frame, the finishing roller having journal pins ournaled on the said plates, and springs arranged between the forward ends of the plates and the frame.

4. A machine of the character specified com risin a main frame a ackin roller arranged transversely of the frame intermediate its front and rear ends, an auxiliary frame pivoted at its front end to the main frame and carrying at its rear end the packing roller, and a connection between the main frame and the rear end of the auxiliary frame for adjusting said rear end of the auxiliary frame vertically, wheels for supporting the front end of the main frame, and a finishing roller for supporting the rear end of the main frame.

5. A machine of the character specified comprising a main frame, a packing roller 7 arranged transversely of the frame intermediate its rear and front ends, an auxiliary frame pivoted at its front end to the main frame and carrying at its rear end the packing roller, and a connection between the 10 main frame and the rear end of the auxiliary frame for adjusting said rear end of the auxiliary frame Vertically.
