ROAD ROLLER AND SCARIFIER.

Application filed September 24, 1924. Serial No. 739,489.

Our invention relates to an improvement in road rollers ant, scariiiers and is more particularly directed to the production of'a convenient and economical device which may be used in connection with road building and improvement operations and which will be adaptable for use in connection with road maintenance.

I-Ieretofore there have been produced various types of road rollers powered with internal combustion engines, but such are relatively expensive in first cost and also in operatlon. Further, such roller-s are cumbersome and primarily usable only on relatively large operations.

Now it is the object of our invention to provide means whereby the well known Fordson tractor may be .adapted to the production of a road roller which will be highly efficient, economical and of a wide range of utility, and further to provide means whereby scarifying means may be applied to the roller with efficiency.

As a result of our invention there is provided a road rolling and scarifying device essentially including a Fordson tractor which results in a device of such simplicity as to be operable by relatively unskilled hands and one for which repair parts and service are obtainable almost any where throughout the country.

Having now indicated in a general way the nature, purpose and advantage of our invention, we will proceed to a detailed description thereof with reference to. the accompanying drawings in which we have illustrated a preferred embodiment and in which:

view on line 1 Figure 2 is a perspective view of means for securingthe roller wheels to their axle.

Figure 3 is a side elevation partly in sectionof means for supporting the frame of the roller. V

Figure a is an end view, partly in section of the subject of Figure 3.

Figure 5 is a plan view showing scarifying section toward each other throughout a major portion of their length and braced by means of cross members 0 and cl intermediate their ends and by a plate 6 adjacent the forward end. I The Fordson tractor unit a is mounted on and supported by the frame, the forward end being supported by engagement of the cross member 0 with the forward end of the crank case of the unit, in place of the front axle assembly as shown in Figure 1 The rear end of the tractor unit is supported by means of brackets e secured to the side members of the frame. The brackets 6, one of which is shown in detail in Figures 8 and 4, are secured oppositely to the side members-of the frame by means of rivets or bolts and are. provided with a clamping member f adapted to embrace the rear axle housing 9 of the Fordson tractor adjacent its opposite ends and secure it to the bracket .by which it is supported from the frame.

Thus it will be observed that the tractor unit is supported by the frame, 5, at its forward'end by cross member 0 and at its rear end through being clamped to brackets e secur-ed. to the side members of the frame.

Beneath the forward end ofthe frame I) is a wide single wheel or roller 2', preferably made in two sections as shown. The roller 6 is mounted on an axle j carried by an inverted U shaped frame is, secured to a hanger Z pivotally mounted beneath the forward end of the frame Z). Secured to the frame is is avertical shaft in uponthe upper end of which is secured a segmental gear n,

adaptedto be rotated, for turningfthe roller 7 i and steering the machine, by means of a suitably mounted worm gear operable by a hand wheel at the operators station through a shaft 1) leading to the rear of the machine.

The machineis driven by a pair of wide tread wheel orroller members g which with the rollers 2' act to roll a surface of substantial width. The rollers Q are mounted on an axle r mounted in bearings 8 formed in brackets e. The vdrive from rear axle t of the Fordson tractor unit is effected by means of sprockets a secured to the ends of the Fordson tractor axle, in place of the usual wheels, through chains 1), to sprockets w on the hubs m of rollers g; and which may be of a size to give any desired gear reduction.

It will now be observed that the rollers g are driven from the rear axle of the Fordson tractor and if the rollers or Wheels Q are mounted so as to turn on the axle r, as

shown in Figure 1 the rollers a will have the benefit of the difierential included in the Fordson tractor drive. However under certain circumstances the differential may be distinctly disadvantageous as when one of the rollers g is running on soft or slippery surface. In order to enable the elimination of the action of the Ford differential on the rollers 9 under such circumstances, the

ends of the hubs m are slotted as at y and there are providedwheel retainers 2 adapted to slip over and be secured to the axle by means of bolts to retain the rollers thereon. The retainers are plain on one side and are provided on the other side with ridges or keys it. If the effect of the differential be desired, the retainers are put on the axles with their plane sides against the ends of the hubs and secured to the axle, in this position the rollers may turn relatively to the retainers and to the axle 1". If, on the other hand, the effect of the differential is to be eliminated, the retainers are reversed and the keys i entered in the slots y in the hubs, so that when the retainers are secured to the axle the rollers will be locked thereto and both rollers will act as a unit. In order to provide for convenience in cranking the engine of the Fordson tractor there is applied to the end of the lateral power take-off shaft a starting crank 4 accessible to the operator when at the operators station. The end of the power take off shaft is covered by means of a housing 5, secured to the engine crank case and extended beyond the end of the power takeoff shaft for supporting the starting crank, as shown in Figure 2.

As we have indicated, our invention in cludes the application of a scarifyingv device to the roller structure, the scarifier and its application is shown in Figures 5 and 6.

Extending between the side members of frame 6 are a pair of shafts 6 and 7 sup ported by brackets 8 and 9 respectively secured to the frame members. At intervals on shaft 6 are rotatably mounted arms 10 separated by spacers 11 to which are secured levers 12 at the free ends of which are provided clamps 13 in which are adjustably secured scarifying tools 14-. At intervals on shaft 7 are secured cranks '15 which are pivotally connected. to links 16, which in turn are pivotally secured to levers 12. Secured adjacently to one end of shaft 7 is a segmental gear 17 adapted to be turned by a worm 18, on the end of a vertical shaft 19 mounted in a bracket 20 and provided on its upper end with a hand wheel 21.

It will now be clear thatthe scarifying device is positioned beneath and supported by the frame I) and operates between the rollers or wheels 9. The scarifying tools 14: may be adjusted in their clamps 13 and through rotation of shaft 7 by means ofhand wheel 21, which results in raising or lowering the levers 12 whiclnas has been .described, are pivotallysupportedby shaft 1) through arms 10. y

The operation of the device embodying our invention will, it is believerhbe obvious,

butit will be noted that without any change in the Fordso-n tractor unit, beyond the removal ofthe frontaxle assembly and rear wheels, there is provided an efficient and economical road rolling and scarifying unit to which motive means adapted for other purposes can readilybe connected.

It will be understood that while in the description of the preferred embodiment of our invention we have referred to the Fordson tractor, any suitable form of tractor unit may be utilized, or, if desirable, a power unit may be built up, without departing from our invention.

Having now fully described our invention,
