Abstract
Abstract A coal planer or other mineral winning machine has provision for adjustment in order to take into account the thickness of the seam being worked. Continuous adjustment of the machine is effected by a control bar which extends along the face and cooperates with a follower which is carried on the machine and repositions one or more tool carrying parts of the machine by way of mechical or hydraulic linkages.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
115 words
A mining installation comprising a conveyor extending alongside a face to be worked, a guide on said conveyor; a planer having a base guided for movement along said guide, a superstructure articulated to said base, and an upper part supported on the superstructure and adjustable relative thereto, said superstructure having an arm extending rearwardly across the conveyor, a guide member extending parallel to said conveyor, along which said arm is adapted to slide, a control member extending generally parallel to said guide member, means carried by said planer and adapted to follow said control member and to adjust the position of said upper part as it varies in position in contact with the control member.
Claim 2
Dependent Claim
115 words
A mining installation comprising a conveyor extending alongside a face to be worked, a guide on said conveyor; a planer having a base guided for movement along said guide, a superstructure articulated to said base, and an upper part supported on the superstructure and adjustable relative thereto, said superstructure having an arm extending rearwardly across the conveyor, a guide member extending parallel to said conveyor, along which said arm is adapted to slide, a control member extending generally parallel to said guide member, means carried by said planer and adapted to follow said control member and to adjust the position of said upper part as it varies in position in contact with the control member.
Claim 3
Dependent Claim
89 words
A mining installation including a conveyor extending along a face to be worked, a mineral winning machine having a first adjustable body part equipped with tools for removing mineral from the face as the machine iS moved along the face parallel to the conveyor, an elongate control member extending along the face generally parallel thereto and a follower cooperating with the control member and arranged to adjust the position of the said part of the machine in accordance with the location of the said member relative to the machine.
Claim 4
Dependent Claim
89 words
A mining installation including a conveyor extending along a face to be worked, a mineral winning machine having a first adjustable body part equipped with tools for removing mineral from the face as the machine iS moved along the face parallel to the conveyor, an elongate control member extending along the face generally parallel thereto and a follower cooperating with the control member and arranged to adjust the position of the said part of the machine in accordance with the location of the said member relative to the machine.
Claim 5
Dependent Claim
30 words
A mining installation as claimed in claim 2, wherein the follower cooperating with the control member is formed or provided on a lever pivoted on another part of the machine.
Claim 6
Dependent Claim
36 words
A mining installation as claimed in claim 3, wherein the lever is a two-armed lever one arm of which engages with the control member and the other arm of which engages with the said first part.
Claim 7
Dependent Claim
48 words
A mining installation as claimed in claim 3, wherein a lever arranged to follow the said control member is linked to a second lever which engages with the said first part and adjusts the same in accordance with the motion of the linkage consisting of the two levers.
Claim 8
Dependent Claim
25 words
A mining installation as claimed in claim 2, wherein the follower includes an axially displaceable push rod slidably supported by another part of the machine.
Claim 9
Dependent Claim
34 words
A mining installation as claimed in claim 6, wherein the said push rod bears against a lever system linked to and arranged to adjust the position of the said first part of the machine.
Claim 10
Dependent Claim
83 words
A mining installation as claimed in claim 6, wherein a further part of the machine is adjustable and the push rod is displaced axially through the intermediary of a lever supported for pivotal motion in two planes at right angles and provided with the follower, motion of said lever in one plane serving to displace the push-rod and motion of the lever in the other plane serving to actuate other means for controlling the position of the further adjustable part of the machine.
Claim 11
Dependent Claim
39 words
A mining installation as claimed in claim 8, wherein said push rod and other means are arranged to control the supply of pressure fluid to pressure fluid operated means controlling the position of the said parts of the machine.
Claim 12
Dependent Claim
29 words
A mining installation as claimed in claim 9, wherein the lever is carried upon a shaft, rotation of which controls the supply of pressure fluid to said further part.
Claim 13
Dependent Claim
26 words
A mining installation as claimed in claim 10, wherein the fluid is controlled by means which pressurise the fluid or by means which control its flow.
Claim 14
Dependent Claim
26 words
A mining installation as claimed in claim 2, wherein the said first plough part has therein an open channel in which the control bar is received.
Claim 15
Dependent Claim
90 words
A mining installation as claimed in claim 2, comprising a guide frame assembly disposed on the side of the conveyor remote from the face, said assembly being constituted by a plurality of individual guide frames, adjustable support means on each said frame, the control member being segmented and extending parallel to the face and being carried on said supports, the segments of said member being angularly adjustable in position thereby to vary the overall shape of the control member, the control member being disposed at a level above the conveyor.
Claim 16
Dependent Claim
33 words
A mining installation as claimed in claim 13, wherein each of at least some of the segments so supported is carried by a component of a pressure fluid operated piston and cylinder unit.
Claim 17
Dependent Claim
26 words
A mining installation as claimed in claim 14, wherein each of said units is supported by or housed within an upstanding part of the frame assembly.
Claim 18
Dependent Claim
30 words
A mining installation as claimed in claim 13, wherein each of at least some of the segments is carried at the end of an arm which extends across the conveyor.
Claim 19
Dependent Claim
23 words
A mining installation as claimed in claim 16, wherein each of the arms is pivoted to an upstanding part of the frame assembly.
Claim 20
Dependent Claim
39 words
A mining installation as claimed in claim 17, wherein each arm is one arm of a bell crank lever, relative to which the guide member is adjustable, and which bell crank lever is itself adjustable about its pivot axis.
Claim 21
Dependent Claim
23 words
An installation as claimed in claim 16, wherein said arm is supported in caNtilevered fashion by an upstanding part of the frame assembly.
Claim 22
Dependent Claim
29 words
A mining installation as claimed in claim 13, wherein each guide frame is supported above the floor in a guide and is movable towards the face by a ram.
