2 Claims.
This invention relates to ground ripping tools. Such tools comprise rigid ground engaging teeth, customarily mounted rigidly on a frame so that to clear the teeth from the ground, the frame must be lifted.
The principal object of my invention is to improve the means for mounting the teeth on the supporting frame so that said teeth may be lifted and held clear of the ground without lifting the frame. This feature makes my improved structure particularly suited for mounting on the frame of a wheel supported scraper, in connection with the operations of which a ripper is frequently used.
A further object is to provide means to enable the digging depth of the teeth to be easily altered, without changing the level of the supporting frame. All operations and manipulations ofthe ripper teeth may therefore be carried out without moving the supporting frame and which movement, with a scraper bowl also supported thereon, would detrimentally affect the operation of the scraper.
A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.
These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.
In the drawings similar characters of reference indicate corresponding parts in the several views:
Figure 1 is a fragmentary view side elevation of a wheel supported frame, showing my improved ripper teeth mounting, partly in section and with the teeth in ripping or digging position.
Figure 2 is a similar view showing the raised or folded.
Figure 3 is a fragmentary sectional plan on line 3-3 of Fig. 2.
teeth Referring now more particularly to the char- I Secured on and projecting rearwardly from the beam I are transversely spaced bracket plates 4, between which the shank 5 of a ripper tooth 6 is disposed. The tooth is disposed at a forward angle to the shank and on its lower end carries a Wear and point shoe '1. The shank between the plates is provided witha pair of vertically spaced holes 8 disposed, in a line parallel to the forward edge of the shank, toalternately receive a pivot pin 9 supported by and extending between the plates. j
The shank at its upper end and above the bracket plates is bifurcated to form spaced ears III to receive the head II of a piston rod I2 therebetween. This rod projects fromthe rear end of a hydraulic cylinderl3 of the type commonly used to control implement movements, the
cylinder being pivoted at its forward end in connection with ears I4 mounted on top of beam I ahead of plates 4.
The head II is pivoted on the ears Iil by means of a transverse pin I5 removably projected through said head and through either one of a pair of holes IS in the ears, the holes being spaced the same as holes 8 and disposed in a line parallel thereto. In operation, it is intended that when the pin 9 is in the lower hole 8, the pin I5 is in the upper hole I6, and vice versa. Changing of pin 9 to the upper hole 8 will obviously lower the shank and tooth relative to the frame, and correspondingly changing the position of pin I5 will leave the cylinder and piston with the same leverage on the tooth as before.
When the tooth is in a digging position, it is disposed at a forward angle to the ground, the shank issubstantially vertical and the piston rod is retracted in the cylinder, as shown in Fig. 1. In order to prevent the horizontal digging pressure exerted against the tooth from swinging the same back from proper position, I mount a rigid stop bar I! between the plates 4 to engage the forward edge of shank 5, whether the bolt 9 is engaged with the upper or lower hole 8.
When the use of the tooth is not desired, the piston rod I2 is advanced, swinging the shank 5 rearwardly and the tooth upwardly until point I engages the under side of beam I, as shown in Fig. 2. Since the teeth are alined with the frame beams I, while the bowl and wheels are obviously between said beams, the teeth will act on the earth laterally out from the wheels and bowl. By this arrangement the teeth, if digging at the same time that the bowl is loading, will not interfere with the operations of the teeth.
The plates 4 are formed with slots I8 in front of the shank when the blade is in the above tually raise and lower the tooth. It will also be seen that the tooth may be raised and relatively folded against the frame irrespective of which hole 8 engages pin 9, and that the wedge 19 will serve to retain the shank in either case. Since a certain amount of dirt maybe lifted with the tooth, the inner plate A is preferably members, a pivot pin removably supported by said members, the shank having vertically spaced holes to selectively receive the pin, a hydraulic cylinder mounted lengthwise on said beam and operatively connected with the shank to swing the latter about said pin, and a rigid stop element mounted between the members engaging the forward edge of the shank above the pin when the tooth is in ground engagement; said holes being centered on a line parallel with said shank edge, whereby the digging angle of the tooth remains the same, and the. shank engages said stop, irrespective of any change in cut out ahead of the shank as at 20 to discharge versely spaced supporting members projecting such dirt, the outer plate being left uncut for-the sake of appearances.
From the foregoing description it will be, readily seen that I have produced such a device as substantially fulfills'the objects of the invention as set forth 'herein.' t
Whilethis specification'sets forth in detail the resent and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form adeparture from the spirit of the invention, as defined by the appended claims.
