Abstract
Abstract The apparatus comprises a segment former constituted by an endless travelling body providing a continuous surface in spaced parallel relation to the inner surface of a container to be lined. The travelling body is in the form of a pair of axially spaced endless chains trained about coaxial sprockets and carrying substantially rectangular plates which are vertically oriented and arranged to form the continuous surface. The endless chains travel about curvature defining guides facing the wall of the container to be lined. A non-shaped refractory is supplied to the space between the segment former and the inner surface of the container, and is rammed by a ramming device. The container is mounted on a rotary table which is rotated during the lining operation, and the travelling body, due to the engagement of the continuous surface with the rammed refractory, moves in the same direction as, and in synchronism with, the rotation of the rotary table, so that there is no relative angular movement between the continuous surface of the segment former and the inner surface of the container. The segment former prevents collapse of the compacted refractory while the latter is "setting."

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
173 words
In apparatus for automatically lining a container with a nonshaped refractory, of the type including a rotary table mounting the container, drive means for rotating the table, a segment former positionable in the container in spaced relation to the inner surface of the container to define a space into which the non-shaped refractory is supplied, and means operable to ram the supplied refractory in such space to form a refractory lining on the inner surface of the container: the improvement comprising, in combination, a segment former constituted by an endless travelling body providing a continuous surface in spaced parallel relation to the inner surface of a container to be lined; and means mounting said travelling body for movement of said continuous surface in the same direction as, and in synchronism with, the rotation of said rotary table; whereby there is no relative angular movement between said continuous surface and the inner surface of the container, said travelling body comprises an endless series of vertically oriented, substantially contiguous, flat plates providing said continuous surface.
Claim 2
Dependent Claim
173 words
In apparatus for automatically lining a container with a nonshaped refractory, of the type including a rotary table mounting the container, drive means for rotating the table, a segment former positionable in the container in spaced relation to the inner surface of the container to define a space into which the non-shaped refractory is supplied, and means operable to ram the supplied refractory in such space to form a refractory lining on the inner surface of the container: the improvement comprising, in combination, a segment former constituted by an endless travelling body providing a continuous surface in spaced parallel relation to the inner surface of a container to be lined; and means mounting said travelling body for movement of said continuous surface in the same direction as, and in synchronism with, the rotation of said rotary table; whereby there is no relative angular movement between said continuous surface and the inner surface of the container, said travelling body comprises an endless series of vertically oriented, substantially contiguous, flat plates providing said continuous surface.
Claim 3
Dependent Claim
34 words
In apparatus for automatically lining a container, the improvement claimed in claim 1, in which said mounting means comprises a pair of vertically spaced endless chains trained about respective pairs of longitudinally spaced sprockets.
Claim 4
Dependent Claim
51 words
In apparatus for automatically lining a container, the improvement claimed in claim 2, including respective curvature forming guides engaging each endless chain in that run thereof facing the inner surface of the container, and constraining the associated chain to a curvature conforming to that of the inner surface of the container.
Claim 5
Dependent Claim
87 words
In apparatus for automatically lining a container, the improvement claimed in claim 3, including a main frame; said rotary table being rotatably mounted on a lower portion of said main frame; a support on the upper portion of said main frame mounted for movement on said main frame toward and away from the axis of rotation of said rotary table; and a guide bar on said support extending downwardly therefrom toward said rotary table; said sprockets being rotatably supported on the lower end of said guide bar.
Claim 6
Dependent Claim
55 words
In apparatus for automatically lining a container, the improvement claimed in claim 4, in which said guide bar is vertically displaceable on said support; an endless chain trained over pulleys on said support and having one end secured to said guide bar; and a counterbalancing weight secured to the other end of said endless chain.
Claim 7
Dependent Claim
51 words
In apparatus for automatically lining a container, the improvement claimed in claim 5, including a rammer secured to said guide bar adjacent the lower end thereof; and a rammer butt operable by said rammer and extending into the space defined by said continuous surface and the inner surface of the container.
Claim 8
Dependent Claim
122 words
In apparatus for automatically lining a container, the improvement claimed in claim 6, including a feeler mounted on the lower end of said guide bar to extend laterally therefrom into engagement with the inner surface of the wall of a container in advance of said segment former considered in the direction of rotation of said rotary table; means biasing said feeler to engage the inner surface of a container; sensing means responsive to movement of said feeler from a predetermined extension thereof; and means operable by said sensing means to displace said support toward and away from the axis of rotation of said rotary table to maintain constantly a fixed spacing between said continuous surface and the inner surface of the container.
Claim 9
Dependent Claim
109 words
In apparatus for automatically lining a container, the improvement claimed in claim 7, including a hopper on said support arranged to contain a supply of a non-shaped refractory, a sub-hopper adjacent the lower end of said guide bar; means operable to deliver the refractory from said hopper through said guide bar to said subhopper; a mixer mounted adjacent the lower end of said guide bar and receiving the refractory from said subhopper to re-mix the refractory; and feeding means connected to said mixer and discharging the re-mixed refractory therefrom into the space between said continuous surface and the inner surface of the container for compacting by said rammer butt.
Claim 10
Dependent Claim
87 words
In apparatus for automatically lining a container, the improvement claimed in claim 8, in which said weight counterbalances the weight of said guide bar and the components mounted on said guide bar; the reaction of said rammer butt on said rammer mounted on said guide bar resulting from an increase in the height of the refractory in the space between said continuous surface and the inner surface of the container moving said guide bar and the components supported thereby upwardly as the height of the lining increases.
