Abstract
Abstract Apparatus for the uniform distribution of material issuing from blast pipe lines has a terminal distributor arranged directly on the discharge end of a horizontal or slightly rising conveyor pipe line, with the distributor including a drivable and swingable discharge trough. The discharge trough is mounted for oscillation, in a predetermined adjustable range, about the axis of the conveyor pipe to direct the material at an angle to the axis either laterally or downwardly. The conveyor pipe includes an intermediate section and a terminal section having a diameter larger than that of the intermediate section. A guide rail extends above the material receiving area and mounts the terminal section for reciprocation parallel to its axis with the major part of its length being telescopable over the intermediate section. The terminal section may be designed as an elongated hood with a detachable bottom wall which is detached from the hood as the terminal section is retracted and which is attached to the hood as the terminal section is extended.

Claim 1
Independent Claim
313 words
An apparatus for the uniform distribution of material issuing from blast pipe lines, of the type having a terminal distributor arranged directly on the discharge end of the horizontal or slightly rising conveyor pipe line, with the distributor including a drivable and swingable discharge trough; the improvement comprising, in combination, means operable to oscillate said discharge trough in an adjustable predetermined range about the axis of said conveyor pipe so that said trough directs the material at an angle to the axis of said conveyor pipe both laterally and downwardly; said conveyor pipe including an intermediate section and a terminal section having a diameter larger than that of said intermediate section; a guide rail extending above the material receiving area; means mounting said terminal section on said guide rail for reciprocation parallel to the axis of said terminal section with the major part of its length being telescopable over said intermediate section; said conveyor pipe line including an outwardly extending section externally of a building wall enclosing said material receiving area, and terminating in an ejector extending into said terminal section and constituting said intermediate section; said terminal section being formed of an inverted trough-shaped hood reciprocable over said ejector; a bottom wall disengageably connectible to said hood to form therewith a tubular enclosure; automatically opening and closing holding devices operable to sealingly connect that portion of said bottom wall downstream of said ejector with the bottom edges of said hood; guide means upstream of said ejector movably receiving that portion of said bottom wall disengaged from said hood; said bottom wall comprising rigid individual sections; hinges interconnecting adjacent sections; laterally projecting pins on each section; and a stand constituting said guide means and engageable with said pins whereby that portion of said bottom wall disengaged from said hood is arranged with said individual sections suspended from said stand and in folded relation.

An apparatus for the uniform distribution of material issuing from blast pipe lines, of the type having a terminal distributor arranged directly on the discharge end of the horizontal or slightly rising conveyor pipe line, with the distributor including a drivable and swingable discharge trough; the improvement comprising, in combination, means operable to oscillate said discharge trough in an adjustable predetermined range about the axis of said conveyor pipe so that said trough directs the material at an angle to the axis of said conveyor pipe both laterally and downwardly; said conveyor pipe including an intermediate section and a terminal section having a diameter larger than that of said intermediate section; a guide rail extending above the material receiving area; means mounting said terminal section on said guide rail for reciprocation parallel to the axis of said terminal section with the major part of its length being telescopable over said intermediate section; said conveyor pipe line including an outwardly extending section externally of a building wall enclosing said material receiving area, and terminating in an ejector extending into said terminal section and constituting said intermediate section; said terminal section being formed of an inverted trough-shaped hood reciprocable over said ejector; a bottom wall disengageably connectible to said hood to form therewith a tubular enclosure; automatically opening and closing holding devices operable to sealingly connect that portion of said bottom wall downstream of said ejector with the bottom edges of said hood; guide means upstream of said ejector movably receiving that portion of said bottom wall disengaged from said hood; said bottom wall comprising rigid individual sections; hinges interconnecting adjacent sections; laterally projecting pins on each section; and a stand constituting said guide means and engageable with said pins whereby that portion of said bottom wall disengaged from said hood is arranged with said individual sections suspended from said stand and in folded relation.
Claim 3
Dependent Claim
36 words
An apparatus for the uniform distribution of material, the improvement claimed in claim 1 including a drum constituting said guide means; that portion of said bottom walls disengaged from said hood being wound on said drum.
Claim 4
Dependent Claim
109 words
An apparatus for the uniform distribution of material, the improvement claimed in claim 1 in which said holding devices comprise pivotal stirrups, pivotally mounted in beariNg blocks; spring biased pressure plates mounted for limited movement at the free ends of said stirrup; respective control arms on said stirrups; respective rollers rotatably mounted on each control arm; and stop bars engageable with said rollers to swing said stirrup about axes extending parallel to the direction of reciprocation of said hood and against said spring bias; whereby said stirrups, through the respective spring biased pressure plates, automatically connect and disconnect the associated part of said bottom wall relative to said hood.
Claim 5
Dependent Claim
26 words
An apparatus for the uniform distribution of material, the improvement claimed in claim 1 in which said bottom wall comprises an elongated sheet of flexible material.
Claim 6
Dependent Claim
21 words
An apparatus for the uniform distribution of material, the improvement claimed in claim 1 in which said holding devices comprise magnets.
Claim 7
Dependent Claim
40 words
An apparatus for the uniform distribution of material, the improvement claimed in claim 5, including elastic packing interposed between the bottom edges of said hood and said bottom wall, and connected with one of said hood and said bottom wall.
Claim 8
Dependent Claim
170 words
An apparatus for the uniform distribution of material, as set forth in claim 1, wherein said means for oscillating said discharge trough includes a driven gear for oscillating said discharge trough; a first sprocket secured to rotate with said pivot gear; an angle drive including a second sprocket; an arm pivoted on said end terminal section; biasing means urging said arm away from said terminal section; a third sprocket rotatably mounted on the free end of said arm; and endless roller chain trained about said terminal section and engaging said first, second and third sprocket; said distributor including a ring oscillatable therewith; said chain being connected to said ring to oscillate said ring through substantially 180*, a fourth sprocket of said angle drive driven by said second sprocket; a fifth sprocket; a second endless chain trained over said fourth and fifth sprocket to drive said fifth sprocket; a driving sprocket connected to rotate with said fifth sprocket and cooperable with said guide rail to effect reciprocation of said terminal section.
