By such arrangebe placeddiagonally to the line of progresment' the vibratory holder may be so shifted sion with either end in advance. In the pre- Ioo 5o as to bring either one of the rear wheels into ferred arrangement (shown in Fig. l) the bodyalinement with its companion front wheel; frame is supported by the pivoted short front a l temes axle 2 and long rear axle 3. The scraperblade 6 is'arranged to extend across the width of the machine, and is suspended below the body-fraine by suitable raising and lowering devices operated by levers 5. The raising and lowering mechanism is so arranged that the blade may be swung bodily from side to side of the machine; and for the purpose of thus swinging the blade it is drawn by the horizontally-swinging draft-bar 4E, which is pivotally secured at the forward end of the machine and swung by the lever 7.

The blade may be connected in any suitable way for diagonal adjustment, although as a preferred arrangement it is attached to the circle or turn-table 8, having at its center a pivotal connection with the horizontallyswinging draft-bar and provided with the segment-gear 9. l/Vhen it is desired to swing the scraper-blade about its pivotal connection, the hand-wheel shaft 10 is rotated, so as to turn the segment-gear 9 and thereby bring about the required adjustment of the blade.

In order to resist the side draft resulting from the resistance offered by the soil to the scraper-blade, it is desirable to swing the rear axle with reference to the horizontal angle of the blade relatively to the line of progression. W'ith such an arrangement as we propose, either end of the axle may be swung forward, sometimes one and sometimes the other, according to the nature of the work to be done. Vhile an end adjustment of the axle can also be used to some advantage as a means for overcomin g side draft, we iind it desirable to adjust the axle as aforesaid, in order to bring the wheels at one side of the machine in alinement and to extend the axle at one or the other side of the machine after it has been set oblique to the line of progression. As a simple and efficient means of accomplishing this we construct the holder for the rear axle rigid therewith, and provide it with both a pivotal and shifting connection with the body-frame instead of pivotally connecting the axle to said holder and then providing the latter with said shifting connection. Hence the holder or sleeve 12 is provided with pivots or studs 13, which permit vibratory movement of the axle; and these pivots in turn may slide in the guideways 14 in the body-frame, allowing an end thrust or adjustment of the holder, and consequently of the axle.

For shifting said holder along the guideways 14 we select the simple mechanism shown in Figs. 2 and 5, consisting in the chain 15, secured to the bearing and wound about the rotary drum 16. As a means for normally locking said drum so as to hold the bearing in adjustment, a toothed wheel 17, mounted on the drum-shaft 21, is arranged to be engaged by the catch or trip 18, having the spring 2O pressing against the arm or extension 19. The operator, standing upon the platform 22, may shift said holder to one side of the machine or the other by disengaging the catch 18 from the toothed wheel v17 and turning the hand-wheel 23 until the desired adjustment is secured.

For swinging the rear axle about its pivotal connection any suitable device may be employed which is capable of operation, irrespective of the position of the shifting holder with regard to the body-frame of the machine.

As a preferred arrangement, the axle 3 is grasped by the collars 24E at points where a sufficient leverage may be obtained for swinging it in such a manner that the axle is free to slide through them when moved by the shifting bearing. These collars may be operated through the links 26 by the levers 25, both of which may be grasped by the operator standing upon the platform 22. Each lever is desirably provided with a spring attachment 27, which normally engages with the toothed segment 28 for holding the axle in pivotal adjustment. Obviously, by this arrangement, the shifting holder may be adjusted so as to give the axle any desired end thrust, and an independent swinging or vibratory motion may be given to the axle irrespective of the position of its shifting holder.

Referring to Figs. 6, 7, and 8, it will be seen that the companion wheels on either side of the machine may be brought into alinement by inclining the rear axle to the body-frame, as in Fig. 6; that the shifting holder may then be adj usted with reference to the body-frame, so as to bring the latter into a position substantially parallelto the line of progression, as in Fig. 7. In Fig. 8 is illustrated the range of adjustment obtainable in our machine, whereby the wheels may be accommodated to selected relations with furrows or the like, or by which the scraper-blade maybe arranged to deposit soil lifted by it in desired localities.

That we claim as our invention is- 1. In a road-working machine constructed with a wheeled body-frame and a diagonallydisposed scraper-blade arranged between the front and rear wheels, the rear axle pivotally connected with the body-frame, and the pivotal connection supported for ashifting or sliding sidewise movement with reference to the body-frame; and means for adjusting the axle in either a pivotal or sidewise manner independently, whereby the axle can be proj ected laterally from the body-frame by a relative adjustment between the latter and the pivotal connection, and also whereby the axle may be swung into an oblique position by moving it about its pivotal connection irrespective of the position of the same with reference to the body-frame, substantially as set forth.

2. In a road-working machine constructed with a wheeled body-frame and a diagonallydisposed scraper-blade arranged between the front and rear wheels, the rear axle rigidly connected with a holder or bearing which is supported by the body-frame forboth pivotal and sidewise movement with reference thereto, the said axle being provided with means for effecting the pivotal adjustment,
