Abstract
Abstract A tile and gravel embedding machine to operate alone along a trench bottom comprises a hopper with throat, means to direct a line of tile to bottom depth below the throat, combined with machine-controlled propelling means comprising a winch at the front of the machine with cable thereon extending for anchor ahead of the machine, the propelling means driving the winch at extremely reduced speed.

Claim 1
Independent Claim
213 words
Improvement in a machine to operate alone for embedding a line of tile and gravel together in a trench for dispersal of polluting liquids, the machine comprising a frame and supporting means therefor to move along the trench bottom, a hopper for gravel movably mounted for adjustment of its height within the frame and having front and rear walls sloped to a bottom throat cross-wise of the trench centrally of the frame, the said supporting means comprising a bottom plate covering and formed to ride upon the trench bottom under the front wall of the hopper, in combination with means forwardly of the throat to direct a line of tile to decline beneath the throat to a lowest bottom position rearwardly of the throat, and in combination with means for slow, smooth advance of the machine, comprising prime mover means mounted on the frame, a winch mounted on the forward end of the frame and adapted to receive a cable to anchor ahead of the machine and to wind on the winch to advance the machine, and hydraulic means operatively connected to the prime mover means and to the winch to drive the winch, and means connected to the winch to reduce the speed of advance of the machine as the cable winds.

Improvement in a machine to operate alone for embedding a line of tile and gravel together in a trench for dispersal of polluting liquids, the machine comprising a frame and supporting means therefor to move along the trench bottom, a hopper for gravel movably mounted for adjustment of its height within the frame and having front and rear walls sloped to a bottom throat cross-wise of the trench centrally of the frame, the said supporting means comprising a bottom plate covering and formed to ride upon the trench bottom under the front wall of the hopper, in combination with means forwardly of the throat to direct a line of tile to decline beneath the throat to a lowest bottom position rearwardly of the throat, and in combination with means for slow, smooth advance of the machine, comprising prime mover means mounted on the frame, a winch mounted on the forward end of the frame and adapted to receive a cable to anchor ahead of the machine and to wind on the winch to advance the machine, and hydraulic means operatively connected to the prime mover means and to the winch to drive the winch, and means connected to the winch to reduce the speed of advance of the machine as the cable winds.
Claim 3
Dependent Claim
80 words
Improvement in a machine to operate alone for embedding a line of tile and gravel in a trench for dispersal of polluting liquids, as claimed in claim 1, in which the hydraulic means for slow, smooth advance of the machine and of the bottom plate upon the trench bottom comprises a hydraulic motor, a winch driven thereby and speed reduction means to diminish the winch speed to the order of 1:125 to 1:175 of corresponding speed of the hydraulic motor.
Claim 4
Dependent Claim
58 words
Improvement in a machine for operating alone to embed a line of tile and gravel in a trench for disposal of polluting liquid, as claimed in claim 1, having jack means supported by the frame and positioned to thrust up against the sloping front wall of the hopper and move the hopper to adjust the hopper throat height.
Claim 5
Dependent Claim
92 words
Improvement in a machine to operate alone to prepare a line of tile and gravel in a trench for disposal of polluting liquid, as claimed in claim 3, in which the jack means is hydraulic, hydraulic means adjustably connect the jack means to the stated prime mover for operation thereby, the stated hopper is mounted within the frame for height adjustment free from direct contact with the frame, and arms pivotally mounted on the frame and on the hopper to swing with the hopper and restrain the hopper in its height adjustment.
Claim 6
Dependent Claim
79 words
Improvement in a machine to operate alone to prepare a line of tile and gravel in a trench for disposal of polluting liquid, as claimed in claim 3, in which the stated jack means and the hopper are supported on the same side of the hopper and the hopper support comprises two arms of equal length, each having one end pivotally mounted on the hopper and one end pivotally mounted on the frame to swing together with the hopper.
Claim 7
Dependent Claim
104 words
Improvement in a machine to operate alone for embedding a line of tile and gravel together in a trench for dispersal of polluting liquids, comprising a frame, a gravel hopper with rearwardly open throat, a winch for anchor cable, means to Operate the winch comprising prime mover means mounted on the frame and a control flap hinged beneath the hopper to swing up to the rear with flow of gravel from the hopper and to swing down with lack of flow of the gravel, and means connecting the flap with the winch operating means to stop the winch on lack of flow of gravel.
Claim 8
Dependent Claim
104 words
Improvement in a machine to operate alone for embedding a line of tile and gravel together in a trench for dispersal of polluting liquids, comprising a frame, a gravel hopper with rearwardly open throat, a winch for anchor cable, means to Operate the winch comprising prime mover means mounted on the frame and a control flap hinged beneath the hopper to swing up to the rear with flow of gravel from the hopper and to swing down with lack of flow of the gravel, and means connecting the flap with the winch operating means to stop the winch on lack of flow of gravel.
Claim 9
Dependent Claim
172 words
Improvement in a machine to operate alone for embedding a line of tile and gravel together in a trench for dispersal of polluting liquids, the machine comprising a frame and support means therefor adapted to move along the trench bottom, a hopper for gravel movably mounted free of the frame for adjustment of hopper height within the frame and having front and rear walls sloped to a bottom throat crosswise of the trench centrally of the frame, and comprising means forwardly of the throat to direct a line of tile to bottom position rearwardly of the throat, in combination with lifting means supported by the frame and positioned to act upwardly on the sloping front wall of the hopper and move the hopper free from the frame to adjust the hopper throat height from the bottom of the trench, and arms pivotally mounted on the frame and on the hopper to swing with the hopper and restrain the hopper to a substantially vertical path over the tile in the hopper height adjustment.
