Definitions

  • This invention relates to improved apparatus for removing lint, dust, and other foreign substances from the ceiling, walls, and overhead obstructions of an enclosure, such as those of a room containing textile processing machinery from which lint, dust, and other foreign substances are carried by air currents and deposited upon the various surfaces and which, if allowed to accumulate, would drop in bunches upon the machines and the materials being treated, thereby interfering with the proper operation of the machines and affecting the uniformity of the product.
  • Traveling cleaners have heretofore been provided which are mounted upon tracks extending longitudinally over a series of textile machines and are provided with means for projecting currents of air downwardly upon the machines therebeneath and the material in process to blow the lint, dust, and other foreign substances away from the machines and deposit the same upon the floor. Traveling blowers with air blasts directed upward have been suspended from overhead tracks for the purpose of cleaning monitors, ceiling, and other surfaces relatively high .up in the room.
  • the general object of this invention is to provide an apparatus for more effectively removing lint and other foreign substances from all upper surfaces of an enclosure, that is, not only the ceiling but portions of the side walls and all overhead obstructions such as lights, conduits, piping, shafting, motors, ducts, etc., by providing a traveling blower riding above a track located just above head height and constructed and operated to direct a strong blast of air over a large overhead area and in such a way that the various walls, ceiling, lights, and other overhead surfaces and obiects will be reached progressively by air at different angles and at different intensities for more effective cleaning than has heretofore been possible by automatic means.
  • the traveling cleaning unit embodying the present invention is mounted upon a track which is supported from the machines being cleaned and associated with and connected to a traveling unit for projecting currents of air downwardly upon a series of machines therebeneath.
  • An important feature of the invention is that it permits the location of the overhead cleaner above the track on which it rides and in turn permits its blast of air to be directed quite uninterruptedly above the fan without restriction as to direction.
  • Another important feature enables additional thoroughness of cleaning to be secured by combining with the operation previously disclosed in overhead cleaners and with the optional additional intermittent back and forth linear movement of the whole traveling cleaner along the track the further novel movement of complete and continuous revolution of an inclined fan unit about a vertical axis which revolution likewise may be alternately in opposite directions.
  • the invention further provides a novel traveling blower unit for cleaning overhead surfaces and objects, suitable for mounting above a track, including a motor, means operable thereby for moving the unit along the track, a, fan mounted for rotation on a vertically inclined axis in a vertically rotating housing for projecting a blast of air diagonally upward against the surface and objects, means for rotating the fan from the motor, and suitable means for continuously rotating the housing and thus revolving the fan in a complete circle about and on the said vertical axis.
  • a novel traveling blower unit for cleaning overhead surfaces and objects, suitable for mounting above a track, including a motor, means operable thereby for moving the unit along the track, a, fan mounted for rotation on a vertically inclined axis in a vertically rotating housing for projecting a blast of air diagonally upward against the surface and objects, means for rotating the fan from the motor, and suitable means for continuously rotating the housing and thus revolving the fan in a complete circle about and on the said vertical axis.
  • Fig. 1 is a side elevation of a textile machine or series of alinecl textile machines having a track mounted thereon and extending longitudinally thereof with a motor driven unit for projecting blasts of air downwardly upon the machines therebeneath andan independent unit connected thereto having a motor driven fan for projecting a current of air upwardly in a direction angular to the vertical, with means for automatically and continuously revolving the fan and its mounting about a vertical axis and having mechanism for simultaneously reversing the direction of travel of the connected units;
  • Fig. 2 is an end view of the construction shown in Fig. 1;
  • Fig. 3 is a diagrammatic plan view of the typical construction shown in Fig. 1;
  • Fig. 4 is a diagrammatic plan view of an alternative track arrangement illustrating parallel tracks mounted over alined series of machines, the tracks being connected by curved sections to enable the units to travel continuously in the same direction and the means connecting the traveling units being such as to permit them successively to follow the curved sections of the track;
  • Fig. 5 is an enlarged plan view of the up-draft cleaning unit the casing being broken away to show the mechanism for rotating the fan-supporting frame and the mechanism for driving the fan from the vertical shaft of the motor;
  • Fig. 6 is a side elevation of the construction illustrated in Fig. 5, portions of the casing being broken away to illustrate the mechanisms therein.
  • the apparatus is illustrated diagrammatically in Figs. 1, 2, 3, and 4, as applied to a plurality of a series of alined machines having central posts 2 extending vertically upwardly from the machines in alinement and having at their upper ends brackets 3 which support parallel tracks 6.
  • a motor driven unit 5 also may be mounted upon the tracks t, and is provided with means for propelling itself or both units along the tracks and also with means for projecting blasts of air downwardly and transversely across the machines therebeneath.
  • the Lip-draft cleaning unit 6 embodying the present invention when used in combination with unit 5, is spaced from the unit 5 and connected thereto by a rod 1 which is pivotally connected at its ends to the respective units and is adapted to maintain the units continuously in suitably spaced relation, and also to permit the units to pass around curved sections 8 connecting the ends of parallel tracks 4 supported over pluralities or series of alined machines as shown in Fig. 4, or alternately to travel back and forth upon a straight track extending over a plurality of alined machines as shown in Fig. 3, with means for reversing the direction of travel at each end of the track.
  • the up-draft traveling cleaning unit which is shown in detail in Figs. 5 and 6 comprises a carriage 3 having suitably spaced pairs of traction wheels I mounted on the parallel tracks 4.
  • a vertical electric motor II is mounted upon the carriage 9 and has a vertical shaft l3 provided at its lower end with a worm It which engages a worm gear I for driving the shaft I! and the wheels Ill thereon to propel the unit along the track.
  • a plate Ill mounted upon the upper end of the motor I! is provided with a central upwardly extending boss [9 which forms a journal for the upper end portion of the motor shaft l3, the end of which extends therethrough and has fixedly mounted thereon a pulley 2
  • the cylindrical boss l9 also provides an axle upon which is mounted the hub 22 of a circular spider 23 having a downwardly extending cylindrical flange 24 which is provided with internal teeth forming an annular gear.
  • a rigid bracket which extends diametrically across the motor shaft has long and short end sections 26 and 21 which are respectively bolted to the spider 23 and an intermediate integral section 28 which is. suitably inclined to the horizontal upon which the fan is so mounted as to direct the blast of air therefrom at such angle to the vertical that when the fan in its casing is revolved completely about the vertical axis of the motor shaft, as hereinafter described, it will project the blast therefrom over a wide area of the surfaces to be cleaned.
  • a suitable bearing 29 for the fan shaft is provided with a flange 3a which is secured by bolts 3
  • the fan 32 which is provided with a series of inclined blades is fixedly mounted upon the upper end of a shaft 33 which is journaled in the bearing 29 and is provided at its lower end with a pulley 34 which is driven by a belt 35 from the pulley 2
  • the belt 35 runs over intermediate pulleys 36 which are journaled on the respective ends of a shaft in a bracket 31 which is adjustably mounted upon the arm 26 of the bracket which extends diametrically over the motor shaft I3.
  • An angularly truncated casing 38 is secured in circumferentially spaced relation to the cylindrical flange 24 of the annular gear 23 by bolts 38a surrounded by spacing sleeves 38b and encloses said gear, and the mechanism for driving the fan, and has at its lower end an outwardly flanged bell-shaped mouth 43 through which air is drawn through the casing by the rotation of the fan 32.
  • a skeleton guard 38x is mounted upon the top of the casing 38 and surrounds the fan.
  • Suitable means are provided for revolving the fan and its support about the vertical axis of the motor. As illustrated herein this is accomplished by a gear 4! which meshes with the internal teeth 25 of the annular gear 23 and is fixedly secured upon the upper end of a shaft 42 which is journaled in a long bearing sleeve 43 adjustably secured to the periphery of the motor II by the adjusting screw M.
  • the shaft 42 has secured to its lower end a circular frictional disk or wheel 45 which engages the side of one of the tracks 4 upon which the unit travels.
  • the frictional disk 45 drives the shaft 42 and through it rotates the gear 4
  • the disk is a driving agent which serves to rotate the fan-supporting frame against the tendency of the fan to rotate it in the opposite direction.
  • both the fan and the disk contribute to rotating the fan frame, the disk also serving as a brake to determine the speed of rotation.
  • , 36, and 34 drives the fan 32 at high speed. The blast from the fan is thus caused to sweep over a wide area of the surfaces to be cleaned.
  • Usual means for supplying electric current to the motor of the traveling unit 5, when included, for projecting air downwardly upon the machines and to the motor of the up-draft cleaning unit 6 may be provided, or to the traveling up-draft cleaning unit alone in case it is only desired to clean the ceiling, walls, and overhead obstructions of the enclosure.
  • suitable known means are provided for reversing the direction of rotation of the traction wheels at the respective ends of the track such as a rod slidably mounted lengthwise of the carriage and extending at its ends beyond the respective ends of the carriage and adapted to engage suitable, preferably yieldable, abutments at the respective ends of the track and having clutch mechanism operated by the sliding movements of the rod when engaging an a'butment to reverse the direction of rotation of the traction wheels. Meanwhile the fan which is operated from the motor shaft continues always to rotate in the same direction.
  • each unit has a rod 46 slidably mounted for movement longitudinally thereof and adapted to extend beyond the respective ends of each unit, means being provided for slidably moving the rods 46 of both units when the end of the rod of either unit engages the abutment at the end of the track.
  • a rod dl which is parallel to and preferably beneath the spacing rod 1 which connects the cleaning units, is slidably supported upon the rod! by suitable hangers 48.
  • the rod 47 has at its respective ends an enlarged head 49 adapted to engage the projecting adjacent end of the sliding rod 45 of the respective traveling units so that when the end of the rod 55 of either unit engages the abutment at the end of the track the rods 45 of both units will be slidably moved simultaneously in a direction to cause reversal of the direction of rotation of the traction wheels of both units.
  • a well-designed form of cushioned abutment mounted on the respective ends of the track for arresting the unit or units and causing reversal of the direction of travel thereof.
  • a preferred form of abutment is illustrated in Fig. l and comprises a bracket having a standard 50 which is mounted on the end of the track and extends upwardly therefrom and has a tubular arm 51 extending over and suitably spaced from the track in parallelism therewith.
  • a sleeve 52 which slidably fits the tubular arm and extends beyond the end thereof, is connected to or engages a vertically depending abutment plate 53 which is positioned in the path of and adapted to be engaged by the proximate end of the reciprocable rods 45 of a traveling unit as it approaches the end of the track.
  • a coiled spring 54 which is enclosed in the sleeve 52 and interposed between the abutment plate 53 and the end of the tubular arm 5
  • a horizontal U-shaped rod is slidably mounted in the standard 50 with one arm 55 extending axially through the tubular arm 5
  • the other arm 51 of the U-shaped rod extends through a suitable hole in the standard 5!] in parallelism with the arm 5! and through the abutment plate 53 and is provided at its end with a nut 58 which adjustably engages the abutment plate 53.
  • the combined effect of the rotation of the fan on an axis in inclined relation to the vertical axis of the motor and its revolution about said axis provides for cleaning wide areas of the surfaces of the enclosure, whether the track upon which the unit is mounted consists of one or more pairs of parallel tracks connected by suitable bends to provide a continuous track over the machines therebeneath, or a single straight track or plurality of connected tracks terminating in ends requiring the reversal of direction of travel of the cleaning unit. It is obvious that some extra effectiveness in overhead cleaning is secured when the automatic direction-reversing mechanism is utilized because in this way various overhead points are reached by the air blast intermittently at more different angles and intensities on successive trips of the traveling unit than if the unit were always to approach from the same direction.
