Definitions
- This invention relates to a traveling suction cleaning apparatus particularly devised for removing lint, dust and other light material from room and machine surfaces in manufacturing plants, particularly in textile mills. More particularly, this invention relates to an improved material collection system for such a traveling suction cleaning apparatus.
- a preferred type of traveling suction cleaner has been in the form of a track mounted overhead Suction blower having a volute casing, to the inlet or inlets of which one or more suction ducts were connected, with an at least partially foraminate lint collection chamber connected to the outlet thereof.
- the free ends or nozzles of the suction ducts moved closely adjacent surfaces to be cleaned, such as the floor and various parts of the textile machines, and would suck lint and other light material thereinto and convey the same through the casing and into the chamber.
- Means were provided for automatically opening the chamber at predetermined intervals to discharge the collected material into a corresponding receptacle located adjacent the path of travel of the chamber.
- Such a receptacle was usually connected to a suction duct for conveying the material received therein to a point remote from the textile machines. Due to the fact that the collection chamber is automatically emptied quite frequently, the chamber need be of only relatively small capacity.

- some textile plants have a relatively small number of textile machines, so that the savings to be realized from fully automatic disposal of collected lint are less pronounced than in a plant containing a much larger number of machines.
- Such reduced pressure area causes the lint to gather and become intermingled in the central portion of the chamber; away from the side walls and the filter of the chamber, thus assisting in preventing clogging of the 3,1885% Fatented June 15, 1965 interstices of the filter, and permitting a larger amount of material to be collected without adversely afiecting elliciency of the suction cleaner.
- the air tends to flow in a helical manner around the interior of the chamber and creates a low pressure area in the vertical center of the chamber so the lint and other light material collects in the center of the chamber and gradually drops to the bottom thereof.
- a portion of the side wall, preferably opposite the air ingress opening therein, is provided with a foraminate air filter through which the air may escape while the lint is being entrapped Within the chamber.
- the circuitous or helical flow of air past the filter and at substantially right angles to the openings in the filter assists in preventing the filter openings from becoming clogged by the collected lint.
- a door means normally closes the bottom of the chamber and may be opened for emptying the chamber, when desired.
- Another object of the present invention is to provide an improved traveling suction cleaning apparatus of the type adapted to be moved over textile machines having a suction casing with air inlet and outlet ducts, a suction blower fan, a pair of collection chambers, at least one foraminous screen mounted in each of said collection chambers, each of the air outlet ducts and collection chambers being constructed and arranged such that the air stream directed thereinto aids in the prevention of the collection of material on the inside surface of the screens and wherein means is provided for periodically directing an air stream inwardly through the foraminous screens into the collection chambers for aiding in the removal of any material which may have collected on the inside surfaces of the foraminous screens so that the air may be freely exhausted from the collection chamber.

ATTORNEYS United States Patent M 3,188,680 TRAVELING SUCTIUN CLEANER FOR TEXTILE MILLS Robert L. Black, In, Charlotte, NIL, assignor to Parks- Cramer Company, Fitclihurg, Mass., a corporation of Massachusetts Filed Apr. 24, 1961, Ser. No. 105,073 11 Claims. (Cl. 15-312) This invention relates to a traveling suction cleaning apparatus particularly devised for removing lint, dust and other light material from room and machine surfaces in manufacturing plants, particularly in textile mills. More particularly, this invention relates to an improved material collection system for such a traveling suction cleaning apparatus.
Heretofore, a preferred type of traveling suction cleaner has been in the form of a track mounted overhead Suction blower having a volute casing, to the inlet or inlets of which one or more suction ducts were connected, with an at least partially foraminate lint collection chamber connected to the outlet thereof. The free ends or nozzles of the suction ducts moved closely adjacent surfaces to be cleaned, such as the floor and various parts of the textile machines, and would suck lint and other light material thereinto and convey the same through the casing and into the chamber. Means were provided for automatically opening the chamber at predetermined intervals to discharge the collected material into a corresponding receptacle located adjacent the path of travel of the chamber. Such a receptacle was usually connected to a suction duct for conveying the material received therein to a point remote from the textile machines. Due to the fact that the collection chamber is automatically emptied quite frequently, the chamber need be of only relatively small capacity.
I The aforementioned type of traveling suction cleaner is very economical in many textile plants in view of its efficiency in automatically collecting and disposing of residual lint and other light material which usually accumulate on the floor and upon various parts of textile .machines and upon the material being processed. However, some textile plants have a relatively small number of textile machines, so that the savings to be realized from fully automatic disposal of collected lint are less pronounced than in a plant containing a much larger number of machines. There is a need, therefore, for a traveling suction cleaner equipped with high capacity means for collecting and storing large quantities of lint and other light material which may be removed and disposed of manually at relatively infrequent intervals. In view of the space limitations in textile mills, it is important that such a device be constructed in a compact manner without materially increasing the overall height or width of the cleaning apparatus, but at the same time keeping the entire waste collection chamber above head height.
It is therefore an object of this invention to provide a traveling suction cleaner of the general character described with at least one collection chamber for receiving and collecting large amounts of lint and other light material picked up by the suction ducts which chamber has at least one side wall portion, which is foraminate to form an air filter, and wherein the chamber is so connected to the suction blower that the lint-laden air enters the chamber in an offset path relative to the vertical axis of the chamber and flows in a circuitous or helical manner within the chamber so as to create an area of reduced pressure adjacent said axis. Such reduced pressure area causes the lint to gather and become intermingled in the central portion of the chamber; away from the side walls and the filter of the chamber, thus assisting in preventing clogging of the 3,1885% Fatented June 15, 1965 interstices of the filter, and permitting a larger amount of material to be collected without adversely afiecting elliciency of the suction cleaner.
It is another object of this invention to provide a traveling suction cleaning apparatus of the character described wherein the collection chamber comprises a substantially circular, and substantially upright cylinder connected to the blower side of the suction impeller in such a manner that lint-laden air enters the chamber substantially parallel to an imaginary line tangent to the inner periphery of the chamber whereby the air and lint initially impinge against a portion of the inner periphery of the chamber closely adjacent the point at which the lint-laden air enters the chamber. Thus, the air tends to flow in a helical manner around the interior of the chamber and creates a low pressure area in the vertical center of the chamber so the lint and other light material collects in the center of the chamber and gradually drops to the bottom thereof. A portion of the side wall, preferably opposite the air ingress opening therein, is provided with a foraminate air filter through which the air may escape while the lint is being entrapped Within the chamber. The circuitous or helical flow of air past the filter and at substantially right angles to the openings in the filter assists in preventing the filter openings from becoming clogged by the collected lint. A door means normally closes the bottom of the chamber and may be opened for emptying the chamber, when desired.
Another object of the present invention is to provide an improved traveling suction cleaning apparatus of the type adapted to be moved over textile machines having a suction casing with air inlet and outlet ducts, a suction blower fan, a pair of collection chambers, at least one foraminous screen mounted in each of said collection chambers, each of the air outlet ducts and collection chambers being constructed and arranged such that the air stream directed thereinto aids in the prevention of the collection of material on the inside surface of the screens and wherein means is provided for periodically directing an air stream inwardly through the foraminous screens into the collection chambers for aiding in the removal of any material which may have collected on the inside surfaces of the foraminous screens so that the air may be freely exhausted from the collection chamber.
Some of the objects in the invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which- FIGURE 1 is an end elevation of a preferred embodiment of the present invention partially in section and with portions shown schematically;
FIGURE 2 is an enlarged elevation of the upper portion of the apparatus shown in FIGURE 1 with portions broken away and removed for clarity;

FIGURE 7 is a perspective view of the apparatus of the present invention showing one manner in which the collection chambers may be emptied of collected material; and
FIGURE 8 is a sectional elevational view taken substantially along line 88 of FIGURE 5 with portions broken away.
Referring now to the drawings and more particularly to FIGURES 1, 2, 5 and 8, the apparatus generally indicated V at comprises a carriage 11. Carriagell has suitable driven wheels 12.0n one side and an idler wheel 13 on the other side which support carriage 11v on suitable tracks 14, .15. A set of wheels 18 are provided for'holding carriage 11 on tracks'14- and15. Tracks 14, 15 are mounted on suitable-brackets 16, only one of which is shown, which are supported on the fioor'or by a creel 17 mounted on a textile machine 29 over which the tracks 14,15 extend.

The machine 20 represents a row of textile machines in I this instance.
A suction blower unit is mounted on carriage 11 and includesa suitable motor 21 fixed on carriage 11. Motor 21 is provided withsuitable connections'disposed within carriage 11 for driving wheels 12"tomove-carriage 11 over tracks 14, 15. A suction casing 22 is suitably mounted on motor 21 and has a volute blower casing 22arnounted thereon; Suction -casing 22 hasa pair of opposed inlet ducts 25, 26 (FIGURESI and 2) communicativelyconnected thereto. t e V A fan 23 (FIGURE 5) is mounted on a shaft 24 for rotation therewith within casing 22a. Shaft'24 is the out-' put shaft of motor 21 or is operativelyconnected thereto for rotating fan 23. A pair of ducts 25, 26 extend outwardly from casing 22 and are curved downwardly at their-outer ends toward the surfaces tobe cleaned. 'A' pair of flexible ducts or tubes 27, 28(FIGURE 1) are mounted on ducts-25, 26 respectively, and extend downwardly therefrom.
Tubes 27,28 terminate in suitable nozzles 29 which move in close proximity to the surfaces to be cleaned, Whichin this case is shown to be the floor of a textile manufacturing plant or thelike. Suction casing 22 communicates with blowercasing 22a through a substantially circular. opening 22b formed in the proximal Walls there: of and encircling the upper portion of motor 21. Apair of substantially diametrically opposed bafiles 30, 31 (FIG- URE 4) are mounted in suction casing 22 adjacent opening 22!) and serve to direct the air'stream and lint drawn 7 therethrough'inwardly toward motor 21 so that the same 40 may be drawn upwardly into blower casing 22a.
A pairof outlet ducts 32,33 (FIGURE14) are con- 1, 1 V V to the substantially vertical axis of the chamber, or in other words in a substantially tangential manner as shown by the arrows in FIGURE 6.
The air stream is directed into the collection chambers in such a manner that it impinges on the adjacent curved "inside surface thereof and is directed thereby in a circular across foraminous screenmembers38, 39 in a path perpendicular to the .openin'gstherethrough or parallel to the inside surface of thejscreens therefore performing a wiping operation on the inside surface. of the screens which also servesto keep lint and other material. from collect:

chambers. Brackets 48, 49 are respectively mounted on doors 44, 45 and have slots formed therein. Latch members 5i), 51-are'pivotally'mounted on the sides of collection chambers34, 35, respectively, by mounting brackets 52, 53. Latches 50,51 areamanually movable into the slots formed in brackets 48 ,and49 to latch doors 44 and 45 in position to close thedischarge openings. 'A scaling member-54 (FIGURE 6) is mounted on each of .the doors 44,45 to, seal the discharge openings against the passage of air therethrough when. the doors 44, 45 are latched in closed positionl. I 1 V 1 Removal of lint and the like from a collection chamber is easily accomplished after the unit has been stopped at some convenient-point along its trackwayand a receptacle such as 54 shown in FIGURE 7 is placed under the discharge opening, 'To open the discharge opening in either of the collection chambers 34 or 35, the corresponding latch 50, 51 is manually removed from the slot in the corresponding bracket48, 49 and the corresponding door 44, 45 is allowed toswing downwardly about its hinge 46, '47. 'The collected material in the collection chambers 34, 35 will'th en fall by gravity therefrom into the'receptacle. Receptacle 54 may be mounted on suitable wheels or casters 55 which render the receptacle portable for easy handling and positioning under collection chambers 34,35. .A door56 is mounted in asuitable opening in the bottom portion of receptacle 54 forremoval of the material therefrom. A pair of transparent members 57, 60am mounted in vertically spaced openings in jacent the respective collection chambers 34, 35and serve to channel or direct an air stream into each circular collection chamber in a direction off-set laterally with respect the side of receptacle 54 for" visual monitoring of the level of material therein; A'suitable switch 61 (FIGURE 7) is mounted adjacent one end of textile machine 20 for stopping the traveling suction cleaning apparatus in position so that receptacle 54 may be moved beneath either of the collection chambers34fand 35 foremptying the collected materialtherefrom. v v
" At'spaced pointsalong tracks 14, 15, as desired, a filter cleaning device generally indicated at 62 (FIGURES l and 8) may be mounted adjacent the tracksfor directing high velocity air currents inwardly through foraminous screen members 36, 37, 38 and .39 for aiding in the cleaning of theinsidefsurfaces offthe screens of any accumulation of lint and the like. Screen cleaning device 62 comprises an air supply pipe 63 communicating with any suitable source under pressure such as a compressor (not shown). A pair of pipes 64, 65 are connected at one end to air supply pipe 63 and extend outwardly therefrom to a position overlying collection chambers 34, 35 as the same move past said point on tracks 14 and 15. Pipes 6 65 have openings formed in the bottom thereof in the area immediately overlying the path of travel of foraminous screen members 36, 37 for delivering currents of air downwardly against and through the screens. A pair of pipes 66, 67 are connected at one end to pipes 64, 65, respectively, at a point outwardly of the collection cham bers and extend downwardly therefrom to positions spaced outwardly of and parallel to foraminous screen members 38, 39. Pipes 66, 67 have openings therein in the side facing the screens and in the area thereof opposite f-rom the screens for delivering currents of air inwardly against and through screen members 38, 39.
An electric control box 73 is suitably connected to solenoid 72 for energizing the same. Control box 73 has timing means (not shown) for maintaining solenoid 72 energized for a predetermined length of time after initial energization. Since such timing means are well known, an illustration and description thereof is deemed unnecessary. Such a timing means is shown in FIGURE 18 of Us. Patent No. 2,751,621 for example. A switch 74 is suitably connected to control box 73 for initially energizing the same which, in turn, energizes solenoid 72 to open valve 71.
In operation, traveling suction cleaning apparatus 19 travels over textile machines 2t) and removes lint, dust and other light material from the room and machine surfaces. Fan 23 is rotated by motor 2]. drawing an air stream laden with the lint, dust and other light material up through inlet ducts 25, 26 into casing 22a. The lint, dust and other material is discharged from casing 22a by fan 23 and moves outwardly through outlet ducts 32, 33 into collection chambers 34-, 35.
Battles 4t), 41 direct the air stream into collection chambers 34, 35 in such a manner that the air currents within the collection chambers assume a circular path, as aforementioned, causing the lint and other material to collect in the central portion of the collection chambers away from foraminous screens 38 and 39 such that the screens are kept substantially free from lint and other machambers. Also, the circular path of each air current which is parallel to the inside surface of the screens has a tendency to wipe or blow any collected material therefrom and carry it around until it falls to the lower portion or is drawn into the central portion of the corresponding collection chamber. The air currents within the collection chambers escape outwardly and upwardly through screens 36, 37, 33 and 39 leaving the lint and other material within the collection chambers.
The operator of textile machines 29 may visually monitor the amount of material collected in collection chambers 34, 35 through transparent members 42, 43. When enough material has collected within a collection chamber, the operator stops apparatus 10 by means of switch 61, moves receptacle 54 into position and opens doors 44 or 45.
As the suction cleaner travels over tracks 14, 15, the extension 76 on wheel 13 engages the feeler arm 75 of switch 74 to close the same. Switch 74 actuates the electric control box 73 which energizes solenoid 72 to open valve 71. When valve 71 opens, air flows through the air supply pipe 63 into pipes 64, 65, 66, 67 and outwardly through the openings therein against and through screens 36, 3'7, 38, 39 to remove any lint and other material which may have collected on the inside surfaces of the screens.
It will therefore be seen that a traveling suction cleaning apparatus is provided which is capable of operating for relatively long periods of time without the necessity of having the collected material discharged therefrom. A novel method of collecting lint and other light material is provided which is carried out by an improved substantially cylindrical collection chamber which is connected to the corresponding air duct in such a manner as to cause the lint-laden air to enter the chamber in a direction toward a point laterally spaced from the vertical axis of the chamber so the air initially impinges against the curved wall of the chamber and is forced to flow in a circuitous or helical manner which creates a low pressure area centrally or" the chamber and causes the lint to collect thereat in the form of a mass which gradually falls toward the bottom of the chamber. Further, the air stream directed into each chamber aids in keeping the screens clear of lint and other material and means are provided for periodically directing air currents inwardly through the screens to assist in the removal of any lint and other material which may collect on the inside of the screens.
In the drawings and specification, there has been set forth a preferred embodiment of the invention and, although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.
