Abstract
Abstract An improved assembly for securing a digging and pulverizing tine to the tine-carrying plate of a rotary earth-working machine includes a U-shaped tine holder secured to a tine plate to form an open-ended socket for receipt of the shank of a tine. Notches in the end and rearward edge of the tine shank are adapted to receive a pair of pins secured within the socket to establish the working position of the tine. The socket provides the primary load-carrying portion of the assembly in operation. A demountable pin inserted into the socket and into engagement with the tine holds the same in the working position without being subject to any working load and allows rapid tine replacement.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
216 words
In an earth-working implement having a rotor plate for carrying a series of radially projecting expendable tines, the radially inner end of the shank of each tine having a locating notch for a first pin carried by the rotor plate and the rear edge of the shank having a retaining notch for a second pin carried by the rotor plate and arranged such that said tine has an assembly position on the first pin which is rotationally forwardly of the second pin and a working position on both pins which is spaced rotationally rearward of the assembly position, improved means for securing said tine on said pins which comprises a tine holder overlying the rotor plate and including integral radially extending forward and rear supports, said holder and said rotor plate defining a socket which is open at its radially inner and outer ends, the forward and rear supports of said tine holder being welded to the rotor plate and being spaced to receive the tine therebetween in said assembly position and so that the rear support of the tine holder abuts the tine in said working position, and removable means interposed between the forward support and the tine for securing the tine against displacement from the working to the assembly position except as for replacement.
Claim 2
Dependent Claim
216 words
In an earth-working implement having a rotor plate for carrying a series of radially projecting expendable tines, the radially inner end of the shank of each tine having a locating notch for a first pin carried by the rotor plate and the rear edge of the shank having a retaining notch for a second pin carried by the rotor plate and arranged such that said tine has an assembly position on the first pin which is rotationally forwardly of the second pin and a working position on both pins which is spaced rotationally rearward of the assembly position, improved means for securing said tine on said pins which comprises a tine holder overlying the rotor plate and including integral radially extending forward and rear supports, said holder and said rotor plate defining a socket which is open at its radially inner and outer ends, the forward and rear supports of said tine holder being welded to the rotor plate and being spaced to receive the tine therebetween in said assembly position and so that the rear support of the tine holder abuts the tine in said working position, and removable means interposed between the forward support and the tine for securing the tine against displacement from the working to the assembly position except as for replacement.
Claim 3
Dependent Claim
38 words
The invention of claim 1 wherein the retaining notch is disposed at an acute angle to the rear edge of the shank such that the working position is spaced rotationally rearward and radially outward of the assembly position.
Claim 4
Dependent Claim
17 words
The invention of claim 2 wherein said first and second pins comprise a pair of demountable bolts.
Claim 5
Dependent Claim
213 words
In an earth-working implement having a rotor plate for carrying a series of radially projecting expendable tines, the radially inner end of the shank of each tine having a locating notch for a first pin carried by the rotor plate and the rear edge of the shank having an angular retaining notch for a second pin carried by the rotor plate and arranged such that said tine has an assembly position on the first pin which is rotationally forwardly of the second pin and a working position on both pins which is spaced rotationally rearward and radially outward of the assembly position, improved means for securing said tine on said pins which comprises a holder plate overlying the rotor plate and radially extending supports which with said plates define a socket which is open at its radially inner and outer ends, the rotationally forward and rear supports of the holder plate being welded to the rotor plate and being spaced to receive the tine therebetween in said assembly position and so that the rear support of the plate abuts the tine in said working position, and removable means interposed between the forward support and the tine for securing the tine against displacement from the working to the assembly position except as for replacement.
Claim 6
Dependent Claim
213 words
In an earth-working implement having a rotor plate for carrying a series of radially projecting expendable tines, the radially inner end of the shank of each tine having a locating notch for a first pin carried by the rotor plate and the rear edge of the shank having an angular retaining notch for a second pin carried by the rotor plate and arranged such that said tine has an assembly position on the first pin which is rotationally forwardly of the second pin and a working position on both pins which is spaced rotationally rearward and radially outward of the assembly position, improved means for securing said tine on said pins which comprises a holder plate overlying the rotor plate and radially extending supports which with said plates define a socket which is open at its radially inner and outer ends, the rotationally forward and rear supports of the holder plate being welded to the rotor plate and being spaced to receive the tine therebetween in said assembly position and so that the rear support of the plate abuts the tine in said working position, and removable means interposed between the forward support and the tine for securing the tine against displacement from the working to the assembly position except as for replacement.
Claim 7
Dependent Claim
21 words
The invention of claim 4 wherein said holder plate and said forward and rear supports comprise an integral U-shaped tine holder.
Claim 8
Dependent Claim
14 words
The invention of claim 5 wherein said U-shaped tine holder comprises a steel casting.
Claim 9
Dependent Claim
32 words
The invention of claim 5 wherein said removable means comprises a pin extending through aligned holes in said holder and rotor plates and engageable with the forward edge of the tine shank.
Claim 10
Dependent Claim
13 words
The invention of claim 4 wherein said first and second pins are demountable.
Claim 11
Dependent Claim
17 words
The invention of claim 8 wherein said demountable first and second pins comprise a pair of bolts.
Claim 12
Dependent Claim
17 words
The invention of claim 6 wherein said first and second pins comprise a pair of demountable bolts.
