This invention relates to a road tool ofthe character employed in the so called scariat fying of roads provided with surfaces treated with oil, asphaltum or other sub-.
stance that can be out. An object of the invention is to rovide a tool of this description in which t e cutting discs can be manually raised and low-' ered very quickly so as to avoid manholes, rails and other obstacles encountered 1n road In order to properly scarify a road surface, that is to cut oif the ridges of the'surface so as to make said surface more nearl smooth, it is necessary to make frequent sma l adjustments of the discs relative to the road surface so as to more or less follow the surface contour, as the road may be crowned or there may be comparatively lar e uneven surfaces which it is not the function ofthe scarifier to remove. It is also essential, for the reasons stated above, that it be POSSlble to adjust the discs relative to the road surface by relatively great movements qu1ckly executed.
A further object of this invention is to meet the conditions noted above.
The accompanying drawings illustrate the invention:

Fig. 2 is a side elevation of Figure 1.
The parts are shown in solid lines in the positions they occupy when the frame is lowered relative to the wheels, and broken lines indicate the positions of the parts when the frame and its suspended discs are in raised position relative to the wheels.

v12 are shown in four series,
other as. is customary in this ty The frame of the implement is indicated 8 and said frame carries hangers 9 pro vlded with bearings 10 for the shafts '11, on which discs 12 are mounted. The discs in this instance, there being one series on each shaft. The discs of the series on opposite sides of the frame are arranged at an angle to one ane'of road too'l. At its forward end the rame 8 is provided with forwardly projecting arms 13 positioned above the level of'the frame -8 and connected therewith by standards 14. The arms are mounted cantileverwise on the standards. To the forward ends of the membus 13 is secure-d a post comprising a pair of spaced plates 15. Near their upper ends the plates 15 rovide bearings 16 for the trunnions 17 o a trunnion nut 18 which engages a screw 19 provided with a hand wheel 20 for operating the screw.
The screw "19 is provided at its lower end with a head 21 which seats against a shoulder 22 Fig. 7 within a recess 23 of a coupling 24. The. head 21 seats upon an antifriction bearing 25 which is supported by the upper end of a spindle 26 secured in the recess 23 of the coupling by a transverse in 27. The s indle'26 passes through a caring 28 in t e lower end of the post 15, and'is provided with a. collar 29 below the bearing 28.
Below the collar 29 the spindle 26 is journaled in a block 30 which is provided with a transverse slot 31 to receive an axle 32. A bolt 33 in the block 30 passes horizontally through-the axle 32 to prevent relative endwise movement between the axle and block. I
path about the t e axle 32 are provided with wheels 35. A
Secured to the inner faces of the plates 15 is a member 40 which engages the opposite sides of the spindle 26 to prevent lateral tive to the wheels 85, because of the provision of the trunnion nut.
. The frame 8 comprises longitudinally extending members 42 of which, in this instance, there-are six, and the standards 14 are mounted on the two intermediate ones. Four of the frame members 42 are extended rearwar-dly and are provided with bearings 43 for. crank axles 44, there being two bearings for each axle and two axles, one for each side of the machine. Mounted on each pair of the members 42 somewhat forwardly of the bearings 43 is a post comprisin plates 45, 451. The upper ends of the p ates 45 constitute bearings 46 for the trunnions 47 of a trunnion nut 48. The trunnion nut 48 is engaged by a screw provided with two sets of screw- threads 49, 50 respectively. The screw threads 49 are the reverse of the screw threads 50. The upper end of the screw is provided with a hand wheel 51 whereby the screw is turned.
The screw-threads 50 engage a. second trunnion nut 52 having its trunnions 53 pivotally supporting one end of a pair of arms 55 which are. secured by a V-shaped bracket 56 to the crank 57 of one of the crank axles. Each of the crank axles is provided with a round wheel 58, and the rear end of the rame 10 is thus independently and adjustably suspended at opposite sides of the longitudinal center line of the machine. This together with the mechanism described above for adjustably supporting the forward end of the frame constitutes a three point suspension for the frame. The mechanism described for operating the crank 57 is provided for each of-the cranks, that for operating one being a duplicate of the other and, therefore, but one has beendescribed. The arms 55 and crank arm 57 together constitute a lever of which the fulcrum is the hub of the wheel 58. I
The operation of the tool described above is as follows:
Assuming that power is applied to the tongue 39 to draw the tool over the surface of a road that is to be repaired, the hand wheels 20, 51, will be operated to lower the frame relative to the ground wheels 34, 58 so that the discs 12 will cut into the surface of the ridges in the road and thus level off said ridges. In the drawings the screw threads of the screw 19 are right hand and therefore to raise the discs the hand wheel 20 bemade.
chines operate about three-quarters of the be raised and lowered, though by a lesser distance than the rear end. Assumin that the hand wheels 20, 51, have been ad uSted to make the desired cut into the ridges or uneven places of the road, and that because of the approach of the machine toward a man hole it is necessary to raise the discs above the surface of the road, the operator will turn both 'hand wheels 51 to the right. The screw threads 49 being left hand, the
screws will rise relative to the frame so as to swing the arms 55 and cranks 57 u wardly to raise the frame. Turnin of t .e hand wheels 51 also causes the trunnion nuts 52 to travel upwardly on the screws, because the screw-threads 50 engaged by them are right hand. This of course produces more rapid swinging upwardly of the arms 55 and cranks 57 to effect the raising of the frame. As soon as the man hole has been passed, the hand wheels 51 will be turned to the left to e ect lowerin of the frame so as to again swing the discs 12 into cutting relation with the surface of the road.
The operator, by carefully observing the depth of cut made by the forwards'eries of discs, can accurately operate either or both of the hand wheels 51 to make a deeper cut with the rear series of discs in that ortion of the ridge which has just passed t e forward series of discs, so as to reducethe elevation of the ridges by a still greater.
amount.
These tools are of necessity relatively massive in construction and it is clear, therefore, that the frame elevating mechanisms should operate easily and quickly to avoid the imposing of excessive strain upon the operators, since frequent raising of the discs is necessary to clear road obstructions such as man holesand because of working on comparatively short stretches of road and also in cross leveling for adjusting to road inequalities.
Because of the provision of the members 13 and standards 14, the front axle can be turned to position at a right angle to the longitudinal axis of the machine, thus permitting the machine to be turned in a short.
radius and consequently not requirin that .the discs be raised ten or twelve inc es as would be necessary if a short turn could not This is important since the. ma-
time on runs of but one or two blocks before turning.
scribed, the vibrations do not destroy the adjustment as has been experienced with the use of rior constructed lifting jacks designed or speedy raising and owering of the discs. I
Ease of operation of the front screw 19 is insured by reason of apglyin the pressure of said screw vertically t roug the oint of support andreceiving the thrust of t e screw upon an anti-friction thrust hearing.
