' To @ZZ whom it may concern:
Be it known that I, JOHN S. THURMAN, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Dust- Collectors, of which the following is a full,
' partly broken away. Fig. 3 is a top plan with the lid partly broken away. Fig. 4 is an enlarged vertical section of the strainerhood, partlybroken away, online4 4 of Fig. 5. Fig. 4 is an enlarged sectional top plan of a portion of the hood with filter-cloth, partly broken away. Fig. 6 is a vertical sectional detail of the receptacle, showing a modified form of air-conducting pipe. Fig. 7 is a vertical sectional detail of the receptacle, showing a modified form of' shield and air-distributer and Fig. 8 is a vertical cross-section on line 8 8 of Fig. 7.
The present invention relates to dust-collecting devices employed in connection with pneumatic carpet-renovators, the device being attached to the end of the hose or tube leading from the ector which produces the necessary suction in the renovating-tool used in the cleaning of carpets and the like, and particularly stair-carpets, to which the suction method is most advantageously applied. The object of the invention is to provide a collector which shall present a neat appearance, one which can be readily taken apart and cleaned, one which will deposit the dust within a minimumsized chamber, thereby enablin the dimensions of the collector to be materia ly reduced, one which thoroughly lilters the dust-laden air before the latter escapes from the collector into the room, one Whose principle of construction makes the device susceptible of a variety of modifications,
and one possessing further and other advantages better apparent from a detailed description of the invention, which is as follows:
Referring to the drawings, and particularly to Figs. 1 to 5, inclusive, which show one of the forms of my invention, l represents a suitable receptacle or bucket, preferably rectangular in cross-section, the bottom of said bucket having a central opening which communicates with a tube 2, secured to the bottom by-screws 3, passed through the basal flange 4 thereof. Mounted on top of the tube is a wire frame 5, which carries a disk 6, provided with a central depending conical portion 7. The portion 7 serves to spread the dustladen air entering the tube 2 from the hose 8, coupled to the tube 2 by an elbow 8', the disk 6 serving as a shield against the direct impact of thecurrents against the cloth hood or sieve, to be presentlyreferred to. Disposed along two opposite walls of the bucket and in a plane a trifle above the shield or disk 6 are ledges or strips 9 for the support of the open wooden Abox 10, forming the'outer frame of the cloth hood or sieve, by which the dust-laden air -is intercepted and all dust from the air eliminated. The outer faces of the box 10 are covered with a layer ol felt l1, over which is passed a cover of cloth 11', and when the box is in place on the ledges 9 it fits snugly against the walls of the bucket. The sieve or hood bywhich the air is strained of its dust is composed of a sheet or web of cloth formed into a series of vertically-folded sections f, there being interposed between the opposite sides of each pair of folded sections the wooden strips 12, nailed to the box, the edges of the cloth being folded around the strips and interposed between the latter and the walls of the box to which the strips are nailed, Fig. 5. The opposite ends of the cloth are secured to the adjacent ends of the box beneath the overlapping portions of the cloth cover 11, Fig. 4. The construction described prevents any air escaping between the walls of the box and the cloth f, the entire volume of air being obliged to pass through the cloth and become thoroughly iltered. The box is provided with straps 13, by which it may be readily handled and removed from or inserted into the bucket. The top of the box (which collectively with IOO the cloth filter f is here denominated as a strainer-hood or sieve reaches to within a short distance of the top of the bucket and is covered and protected by a perforated top or lid 14, having a marginal bead 15, which when in position on the bucket is engaged by the spring-latches 16 and effectively locked in position.
The dust-ejector is virtually an injector forcing the air coming from the hose 17, which leads to an air-pump (not shown) into the hose 8, the suction thus created in the hose 18 leading to the renovator 19, drawing the dust from the carpet into the hose 18, past the injector-nozzle 20, into the hose 8, as shown by the arrows. The air charged with the d ust passes into the bucket under the shield 6, the conical portion 7 serving to spread the current, which thus indirectly impinges against the folded edges of the filtercloth, the folded edges collectively forming a sieve by which the dust is intercepted, the air being thus fully and completely filtered and in its cleansed condition passing between the folded sections f of thecloth, escaping through the upper edges of the folds into the bucket, thence out through the perforations in the top or lid 14, and out into the atmosphere. The dust thus intercepted falls to the bottom of the bucket, the dust compartment or chamber between the bottom of the hood and the-bucket serving to collect all the dust gathered from a single cleaning. The interposition of the shield 6 serves to protect the cloth against the direct impact of the dustladen air, and hence prevents disintegration of the cloth, as is obvious.
As stated above, the present device is susceptible of various modifications. For example, instead of making connection with the hose 8 through the bottom of the bucket the tube 2 may be tapped by a tube 2, passed through the side wall of the bucket, the outer end of the tube 2 being coupled to the hose 8. In that event, of course, the bottom of the bucket is closed, Fig. 6. Again, as seen in the modifications in Figs. 7 and 8, instead of having the shield 6 disposed centrally the same may be disposed along one of the vertical walls of the bucket. Thus, referring to the last-mentioned figures, the bucket may be provided with a nozzle 21, projecting from the base of one of the vertical walls, which conducts the dust-laden air into a distributer having upper and lower upwardly-inclined walls 22 23, from the mouth of which distributer the air escapes under a horizontal plate 24, overlapping the wall 22, said plate 24 serving not only to support the hood on that side, but serving as a shield to protect the edges of the folds of the filter-cloth against the direct impact of the air-currents. In the last modification a ledge 9 serves to support the opposite side of the hood. So,
also, is the dust compartment or chamber considerably shallower than that shown in the previous form of receptacle. In other respects, however, the last modification does not differ materially from the form first described.
The hood here described and composed of the box 10 with its folds of cloth is a substitute for prevailing forms of bag-receptacles now in use but the present design is not only neater in appearance, but has the advantage of having the same capacity and yet taking up considerably less room. It can be readily taken apart and cleaned, and the sieve in the form of folds protected, as it is, is not liable to become injured or torn.
IfIaving described my invention, what I claim is- 1. A dust-collector comprising a suitable receptacle open at the top, a strainer-hood confined within and snugly embraced by the walls of the same, means for conveying a current of dust-laden air into the receptacle beneath the hood, a shield interposed in the path of the current for arresting the dust, and means providing for the escape of the filtered air through the top of the receptacle, substantially as set forth.
2. A dust-collector comprising a suitable receptacle open at the top, a removable strainer-hood supported within the same a suitable distance above the bottom thereof, means for conducting a current of dust-laden air into the bottom of the receptacle, a shield confined within the receptacle beneath and contiguous to the hood for intercepting the dust, and means providing for the escape of the filtered air through the top of the receptacle, substantially as set forth.
3. In a dust-collector, a strainer-hood comprising a box open at opposite ends, a strainer composed of a dust intercepting web disposed in a series of folds between said open ends, the sides of the folded sections being secured to the adjacent walls of the box, a receptacle embracing the walls of the box, and a dust-intercepting layer interposed between the box and receptacle, substantially as set forth.
4. In a dust-collector, a strainer-hood comprising a box open at opposite ends,a strainer composed of a web of cloth disposed in a series of folds between said open ends, strips inserted on opposite sides between the folds, the edges of the latter being folded against the strips between the latter and the adjacent walls of the box, and the strips secured to the said walls, the ends of the web being secured to the walls opposite thereto and a receptacle snugly embracing the walls of the box, substantially as set forth. l
