The invention relates to road grooving machines.
Due to weather conditions and large amounts of traffic, road pavements, particularly after greatly increase traction and help to eliminate skidding.

Figs. 15, 16 and 17 are filed March 19, 1940, now dated June 10, 1941.
cutters, in a road surface where Referring again to the drawings the reference numeral 20 designates the main frame which is rectangular in plan view and each of its members are preferably channel or U-shaped in cross section. A cross member 2] extends from side to side of the main frame and on this cross member and the forward portion of the main frame two motors 22 and 23 are supported.
The motor 22 drives the machine while it is functioning to cut the grooves in the roadway as will be hereinafter apparent. The motor 23 has for its main function to rotate the cutters. In addition, this motor is used to drive the machine in a direction at. right angles to that in which it moves when cutting the grooves as -will hereafter become apparent.
In cutting a series of grooves, particularly in concrete or cement, hard spots will always oc- If one attempts to synchronize the drive of the machine with the speed of rotation of the On the other hand if a series of particularly hard spots are struck the cutters will slide over the surface or cut the grooves only a fraction of the required depth.
In order to insure the proper functioning of the cutters regardless of the conditions of the roadway a hydraulic coupling or slip clutch 24 is interposed between the motor 23 and its drive shaft 25. Thus if the cutters are held back by road conditions the coupling or clutch 24 will slip and the movement of the machine will be sufficiently arrested to insure the proper functioning of the cutters. The construction of such hydraulic couplings or slip clutches is well known and it is not thought necessary to illustrate same in detail. The motor 22 is provided with the usual well-known transmission for forward and reverse movement.
The shaft 25 has universal joints 26 and 21,
see Fig. 1, and has secured to its end remote from the motor another bevel gear 29 mounted Secured to the ends of shaft 30 are sprockets 3| over which sprocket chains 32 pass and engage sprockets 33 mounted on the wheel axles 34. Thus it will be apparent the rear wheels 35 are driven so as to cause the machine to move.
The shaft 38 is carried. in bearings mounted on an auxiliary frame 36 which is rectangular in plan view and has downwardly extending legs 31 in the region of each of tis corners. These legs are guided in yoke-shaped members 38 secured to the main frame 20 and carry the wheel axles 34 at their lower extremities.
A pump for building up pressure in the cylinder 4| may be driven through the medium of a sprocket and sprocket chain drive 42 from the power shaft 25. Withl this arrangement the entire main frame may be raised or lowered in relation to the auxiliary frame and wheels.
As it will hereinafter becomes apparent the cutters are carried by the main frame. Thus when it is desired to move the machine after a series of grooves has been completed the main frame may be raised and the cutters withdrawn from the grooves. The relative movement between the main frame and the auxiliary frame also permits of setting the machine up to cut grooves of varying depths. In order to observe the amount of movement between the main frame and the auxiliary frame a graduated bar 43 is mounted on the main frame and a pointer 44 on the auxiliary frame.
In normal operation of the machine it is advantageous to have the cutters at the rear end of the machine. In roads where a curb or other obstruction occurs at the edge this would mean a very troublesome manipulation of the machine to complete the grooves. In order to overcome this difi'iculty, means are provided whereby the cutters may traverse the under side of the machine for practically its entire length and cut their grooves.
The operation of the cutters will now be described. The motor 23 has the conventional transmission mechanism of which the gear shift handle is indicated in Figs. 1 and 3. The power shaft 46 has secured to it a sprocket 41 which is connected by a sprocket chain 48 with another sprocket 49 mounted on a shaft 50.
The shaft 58 rotates in suitable bearings, one or more of which may be mounted on a channel member 5| extending from end to end of the machine and suitably secured to the end members of the main frame 28. A pair of sprockets 45 52-52 are secured to the rear end of shaft 58 and sprocket chains 53--53 connect these sprockets 55-55. Two sets of cutting discs are utilized and as the drive for both is identical only one 5 the shafts 51 to which the cutters 59 are secured. 55
Any number of cutters may be utilized and they may be spaced apart as desired. In cutting roadways for trenches a single pair of cutters spaced the proper distance apart will cut through the pavement so that it may be removed prior to dig- 60 ging the trench.
The shafts 54 pass through the boxes 53 and the boxes. and cutters are movable lengthwise of the machine in relation to the shafts 54. The
The bevel gears 69 mesh other bevel gears 6| which are secured to shafts 82 carried in the boxes 56. Sprockets 83 mounted on the shafts 62 through the medium of sprocket chains 84 passing over sprockets secured to the shafts 51 drive these shafts and the cutters.
The side members of the frame 28 are provided with guides 66 for the boxes 58 and other guides 61 are secured -to the under side of the channel member 5| for the other sides of the boxes. Threaded shafts 68 pass through nuts 69 on the boxes and these shafts may be rotated by cranks 10 to move the boxes and the cutters in relation to the machine. Obviously a power take-off from either of the motors might be utilized for rotating the shafts 68.
As heretofore stated when the machine is functioning it is moving forwardly or rearwardly. However, when a series of grooves has been completed in order to prevent much troublesome manipulation of the machine it is moved laterally to bring it in position to cut the next series of grooves. For this purpose the wheels are mounted so they may be swung Fig. 9 shows one of wheels in the position it would assume with the machine being driven forwardly or rearwardly. Fig. 10 shows the wheel swung at 90 so the machine may be driven in a lateral direction.
When the machine is being driven forwardly or rearwardly through the sprocket and chain connections 3|, 32, 33, the axles 34 are free to rotate in their bearings 1| secured to the lower ends of the legs 31. The axles 34 have extensions 12 and in this position the hubs of the wheels are secured by pins 13 to the extensions 12. As shown in Fig. 11 a plurality of openings 14 are provided for the pins 13 to facilitate the alignment of the hubs and extensions prior to entering the pins.
When it is desired to move the machine in a lateral direction the pins 13 are removed thus permitting the wheels to rotate freely on the extensions 12. The extensions 12 are pivoted at 15 in the axles 34 and a locking pin 15 holds the axles and extensions rigid while the machine is functioning. When the wheels are swung to the 0 other position. the locking pins 15 are removed.
One of the rear wheels 35 and one of the front wheels 11 have internal gears 13. These internal gears 18 are meshed by pinions 19 secured to the ends of a shaft 88, mounted in the frame of the machine. The shaft 88 has a sprocket 8| mounted thereon and the sprocket 8| is driven by a sprocket chain 82 which passes over a sprocket 83 mounted on the shaft 84. The shaft 84 is in effect an extension from the power shaft 46, a
O clutch 85 being interposed between the shaft 84 and shaft 46 so that the shaft.84 is only driven when the clutch 85 is thrown. The shaft 88 is provided with a brake indicated at 85 in Figs .1 and 3.
In order to prevent the cutters from becoming unduly heated they are supplied with water through nozzles 81. The nozzles 81 are connected to a pipe 88 which is carried by the box 56. Flexible connections 89 connect the pipes 88 to a tank 98 which is carried on cross members mounted on the auxiliary frame 36. An inlet 9| to the tank may be connected to a convenient hydrant or if water under pressure is not available, a pump 92 may be utilized to pump water from any source of supply into the tank.
Figs. 15, 16 and 17 show the operation of the machine, the machine being designated by the reference character A. In Fig. 15 it is assumed the machine is moving in the direction of the arrow B with the cutters in the rear end of the machine. The machine reaches the position of Fig. 15 and the cutters are then moved to traverse the under side of the machine and complete the grooves. The cutters are then withdrawn from the grooves in the manner heretofore described, the wheels are turned and the machine is moved in the direction of the arrow 0 to the dotted line position of Fig. 16. The cutters are then placed in their operative position, the wheels are again turned and the machine is moved forward in the direction of the arrow D to the dotted line position of Fig. 17. The machine is then reversed and moves in the direction of the arrow E to complete the next series of grooves.
The machine may be utilized for other purposes than cutting grooves in roadways. For instance, slabs of granite or other analogous materials could be cut up in blocks for paving.
Numerous changes in details of construction and arrangements of parts may be made by one skilled in the art without departing from the spirit of the invention as set forth in the appended claims.
