Abstract
Abstract Sugar cane sampler comprising a probe composed of a hollow cylinder with a mouth in the form of a cylindrical saw blade mounted so as to rotate around its axis on a probe chassis and an ejector ram mounted so as to slide in the said cylinder, as well as a guide chassis on which the probe chassis is mounted so as to slide parallel to the axis of the probe and a selective connecting drive to give an advance or reverse movement parallel to the said axis, either to the assembly consisting of the cylinder and ram or to the ram alone, the drive being in the form of a jack, the casing of which is fixed to the guide chassis and the piston of which is directly connected by its rod to the ejector ram.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
114 words
A sugar cane sampler comprising a probe in the form of a hollow cylinder, a cylindrical saw blade mouth at one end of said cylinder, a probe chassis on which said probe is rotatably mounted, a guide chassis on which said probe chassis is mounted so as to move thereon parallel to the probe axis, an ejector ram slidably mounted in said probe cylinder, and a selective connecting drive to move selectively said ram alone and the ram and probe assembly in advance and reverse directioNs, said drive comprising a jack the cylinder of which is fixed to said guide chassis and the piston rod of which is connected directly to said ejector ram.
Claim 2
Dependent Claim
114 words
A sugar cane sampler comprising a probe in the form of a hollow cylinder, a cylindrical saw blade mouth at one end of said cylinder, a probe chassis on which said probe is rotatably mounted, a guide chassis on which said probe chassis is mounted so as to move thereon parallel to the probe axis, an ejector ram slidably mounted in said probe cylinder, and a selective connecting drive to move selectively said ram alone and the ram and probe assembly in advance and reverse directioNs, said drive comprising a jack the cylinder of which is fixed to said guide chassis and the piston rod of which is connected directly to said ejector ram.
Claim 3
Dependent Claim
27 words
A sampler according to claim 1, wherein said selective connecting drive connects the jack piston rod to an element fixed to the rear of said probe cylinder.
Claim 4
Dependent Claim
36 words
A sampler according to claim 1, wherein a restoring device is provided acting on said selective connecting drive in the required direction so as to connect solidly said jack piston rod axially with said probe cylinder.
Claim 5
Dependent Claim
32 words
A sampler according to claim 1, wherein said jack cylinder is housed in a hollow shaft, bringing said probe cylinder into rotation and forming a prolongation to the rear of said cylinder.
Claim 6
Dependent Claim
29 words
A sampler according to claim 1, wherein said jack casing is fixed to an arm which forms an elbow directed upwards at the rear end of said guide chassis.
Claim 7
Dependent Claim
57 words
A sampler according to claim 1, wherein said selective connection drive comprises at least one engaging pin which passes radially through the wall of said jack cylinder in the form of a hollow shaft and slides therefor, the radially interior end of said pin being capable of engaging selectively with a hollow formed on said piston rod.
Claim 8
Dependent Claim
52 words
A sampler according to claim 6, wherein said hollow is an annular groove bounded by two collars, each of which presents on the side opposite said groove a truncated conical face which diverges towards said groove and constitutes an attacking and sliding face for the radially internal end of said engaging pin.
Claim 9
Dependent Claim
108 words
A sampler according to claim 6, wherein said engaging pin is articulated by its radially external end to a lever mounted so as to swivel at an intermediate point on a pivot which is integral with said hollow shaft, the opposite end of said lever being arranged to face an inclined abutment on the axis of said hollow shaft and capable of moving along this axis in relation to said engaging pin, the sliding of the said end opposite to said lever on said abutment accompanying the axial displacement of said abutment to move said engaging pin away from said rod and to move it towards said rod.
Claim 10
Dependent Claim
33 words
A sampler according to claim 8, wherein said abutment is a truncated conical surface formed by a bevelled edge on a sleeve mounted to slide in a cylindrical mounting inside said probe chassis.
Claim 11
Dependent Claim
48 words
A sampler according to claim 8, wherein said abutment is a truncated conical surface formed by a bevelled edge on a sleeve mounted to slide in a cylindrical mounting inside said probe chassis, said sleeve having a stop which projects over the outer surface of said probe chassis.
Claim 12
Dependent Claim
72 words
A sampler according to claim 8, wherein an inclined surface is fixed in a sample ejection position and adapted to come into gradual contact with a stop when a transverse displacement of said sampler towards the said position takes place, to displace said sleeve in relation to said engaging pin in the direction required to make it come out of said hollow and liberate axially said jack rod of said probe cylinder.
Claim 13
Dependent Claim
26 words
A sampler according to claim 8, wherein locking means are provided capable of selectively preventing the axial displacement of said probe chassis along said guide chassis.
Claim 14
Dependent Claim
45 words
A sampler according to claim 8, wherein a device is fixed in a sample ejection position adapted to act on the locking means during the transverse displacement of said sampler towards said position, in the desired direction to bring into action the said locking device.
Claim 15
Dependent Claim
33 words
A sampler according to claim 8, wherein a restoring device is provided acting on locking means for preventing movement of said probe chassis in a direction required to render said locking means inoperative.
Claim 16
Dependent Claim
53 words
A sampler according to claim 8, wherein a switch is fixed to said guide chassis and adapted to come into action to cause said probe cylinder to rotate when said probe cylinder advances from its position at said rear limit stop and to stop this rotation when said probe chassis regains this position.
