Application December 15, 1950, Serial No. 200,926
This invention relates to road working equipment, and more particularly to a hydraulically actuated rooting machine.
An object of this invention is to provide a rooting machine which is particularly adapted to root out the worn tar or compounds used in the expansion joints of concrete pavements in order to facilitate the weather proofing of the pavements for winter months.
Another object of this invention is to provide a hydraulically actuated rooting machine which can be used in various phases of road maintenance, such as removing ice, scarifying old roads, and rooting out worn tar or compounds from the expansion joints of a concrete pavement.
A further object of this invention is to provide a hydraulically actuated rooting machine including a road engaging tool which can be readily raised and lowered with respect to a road surface.
A still further object of this invention is to provide a hydraulically actuated rooting machine which is relatively simple in structure and cheap to manufacture.
The above and still further objects and advantages of the present invention will become apparent upon consideration of the following detail description of the invention when taken in conjunction with the accompanying drawings, wherein:
Figure 1 is a top plan View of the hydraulically actuated rooting machine of the present invention shown connected to a traction device;
Figure 2 is a side elevational View of the hydraulically actuated rooting machine shown attached to a traction device;
Figure 3 is an end elevational view of the hydraulically actuated rooting machine of the present invention taken from the right of Figure 1;
Figure 4 is a sectional view taken substantially along the line 4-4 of Figure 1; and
Figure 5 is an enlarged fragmentary sectional view taken along the line 55 of Figure 1.
Referring now with particularity to the drawings there is shown the rooting machine of the present invention, generally designated by the reference numeral Ii) which includes a mobile frame ll having one end adapted to be connected to a traction device 12.
The mobile frame ll includes a horizontally disposed base l3 which has upstanding end frames l4, l5 secured to the ends thereof. Disposed transversely of the base 13 intermediate the ends thereof is an axle it which is secured to the base l3 and carries ground engaging wheels l1, l8. Projecting forwardly of the upstanding 2 Claims. (01; 262-8) I end frame It is a horizontally disposed extension frame I9 which includes a forwardly projecting hitch bar 28 for attachment to the rearwardly extending support 2! of the traction device If.
Disposed longitudinally of and contiguous to the rearward end of the mobile frame I! is a road engaging tool H which includes an elongated shank 22 and a depending turn-back tooth 23. Suitable universal means designated by the reference numeral 24 and illustrated in Figure 5 are carried by the frame l l and connected to the free end of the shank 22 of the tool 2| for universally mounting the tool on the frame for movement into and out of engagement with the concrete pavement 50 having the expansion joint 5i containing the tar or compound 52 to be rooted therefrom. Th universal means 24 includes an open ended sleeve 25 which is secured longitudinally of the shank 22 of the tool 2| and is provided with a transversely extending opening 26 intermediate the ends thereof. 'Received within the opening 26 of the sleeve 25 is a ball 21 which is supported on the base I3 of the mobile frame I l by means of an upstanding arm 28. Disposed in confronting relation with respect to each other are a pair of abutments 29, 30 which are threadedly supported within the sleeve 25 for movement longitudinally thereof toward and away from each other. The confronting end faces 3|, 32 of the abutments 29, 30 are shaped complementary to the ball 21 and engage the latter for maintaining the ball within the sleeve to form the universal mount.
Operatively connected to the tool 2| are the springs 33, 34 which normally bias the tool out of engagement with the concrete pavement 50. One end of each of the springs 33, 34 is connected to a cross brace 35 carried by the upstanding end frame i5 and the other ends of the springs 33, 34 are connected to an abutment plate 36 which is supported transversely of and beneath the tool 2|.
A suitable hydraulic system is operatively connected to the tool 2! and universally mounted on the frame ll for selectively urging the tool into various positions with respect to the concrete pavement 50. The hydraulic system comprises a jack 3'! including a hydraulic cylinder 38 having one end carried by the tool shank 22 by means of the bracket 39. Slidably supported within the hydraulic cylinder 37 is a reciprocable head, not shown, which is movable longitudinally of the cylinder. Arranged longitudinally of the cylinder 38 is a piston 40 which has one end extending into the cylinder and connected to the 3 reciprocable head and has the other end mounted on a cross brace 41 carried by the upstanding end frame I5 by means of a universal joint 42 of the ball and socket type. The cylinder 38 is provided with a bleeding plug 56 for removing the contents thereof.
Positioned contiguous to the upstanding end frame 14 is a hydraulic pump 43 which is secured to the horizontally disposed base [3 of the mobile frame II. The hydraulic pump 43 includes an actuating arm 44 and a quick action relief valve 49 and is of the type which can be manually actuated to pump hydraulic fiuid therefrom. Connected between the outlet 45 of the pump 43 and the inlet 43 of the hydraulic cylinder 38 is a flexible fluid carrying conduit 41 for carrying hydraulic fluid from the pump 43 to the cylinder 38 of the jack 3'! upon movement of the actuating arm 44. Accordingly upon manual actuation of the actuating arm 44 of the pump 43, pressure is built up and the tool 21! can be urged into any position with respect to the pavement 50 against the oppositely directed force of the springs 33, 34. Upon manual actuation of the relief valve, the pressure is released and the tool can be restored to its normal position due t the springs 33, 34.
Carried by the mobile frame H contiguous to the rearward end thereof are the weights 49', 49', for maintaining the pneumatic tires of the wheels l1, 18 in contact with the pavement surface against the lifting force of the tool 2!.
Supported on the extension frame 19 contiguous to the actuating arm 44 of the pump 43 is a suitable seat 56- permitting the operator to assume a comfortable position while manually manipulating the pump 43.
In actual use the rooting machine of the present invention simplifies and shortens the task of rooting out the worn tar or compound 52 of r the expansion joint 5! of concrete roads'in order to facilitate the weather proofing of the pavement for the winter months. To operate the rooting machine [9, the tool 2| is lined up over the joint 5| to be cleaned, as illustrated in Figures 2 and 3, whereupon the tool is jacked down to the required cutting depth by means of the jack 31 of the hydraulic system. Upon movement of the mobile frame ll in response to the movement of the traction device 12, the tooth 23 of the tool 2! effectively removes the worn tar 52, and when necessary, it removes the chipped concrete along the joints; Due to the universal mounting of the tool the device can be used in other phases of road maintenance such as removing ice and scarifying old roads. Furthermore, when rooting out a joint 5| the universal mounting permits the tool to be maintained within the expansion joint 51 even when the machine is inadvertently or intentionally brought out of line with the joint being cleaned.
Although the embodiment illustrated includes only one rooting tool 21 it is readily apparent that the number of rooting tools can be increased in accordance with the-type of road maintenance.
Although only'one embodiment of the present invention has been described, it is readily apparent that numerous modifications can be made without departing from the spirit of the invention as set forth in the appended claims.
