To all whom it may concern:

Be it known that we, THoMAs J. WINANS and DANIEL M. WINANS, both citizens of the United States, residing at Binghamton, in the county vof Broome and State of New York, have invented certain new and useful Im rovements in Cleaning Apparatus, of wh1ch the following is a specification.

This invention relates to apparatus for cleaningby the. employmentof an air-pump arranged to draw air and dust into a collector adapted to collect the dust and allow. the air to escape.

The object of the invention is to provide an ap aratus of this character of an improve construction, the improvements being directed particularly to making the apparatus very convenientto use, while at the same time being reliable, efiicient and economical in operation.

Our invention is directed particularly -to the provision of a dust-collector mounted upon a suitable support and removable therefrom, and means for making connection to the receptacle through this support, both for the incoming and the outgoing air. This constructionmakes it unnecessary to provide an opening in the wall of the receptacle for the connection of a hose or similar device, it eliminates the necessity of disconnecting a hose every time the dust-collector is to be emptied of dust, and it greatly facilitates the operation of emptying the collector, since for this purpose it is only necessary to raise the collector from'its support by a conveniently disposed handle. The collector may. be carried thus to a suitable place for emptying it, its covering removed, and the dust dumped out, whereupon the collector may be replaced upon its support and the necessary connections theretowill be made merely by the act of placing it upon its support. These and other features of our invention will be more fully setforth in connection with the accompanying "drawings, in which- A' Fi re 1 is a central vertical section of the cleanlng apparatus, Fig. 2 is a top view, and Fi 3 1s a of ig..1. V

' Referring to these drawings, '1 indicates a.

sectional detail view on line 3 3-- casting forming the support for the dustcollector, this casting having two air passageways formed therein. The casting 1 is adapted to be secured to a suitable support or base, whichmay also support the motor and exhauster, forming with the collector the complete cleaning apparatus. At one end of the casting 1, is an upwardly-extending portion, the exterior surface of which is tapered, as shown at 2. A passageway 3 is formed within the casting 1, the upper end ofthis passageway being disposed centrally withinthe tapered portion 2 and the lower end of the passageway being deflected laterally, as shown at 4 in Fig. 3. Suitable connection is made from a vacuum-cleaning device to the port 4- and -passageway 3, and this passageway forms the inlet to the dustcollector. The space around the passageway 3 is. in communication with a tubular opening 5, forming the outlet for the air from the dust-collector, this passageway 5 being connected to the exhauster. In the tapered wall-2, are a plurality of openings 6. In the outlet passage 5, is a relief-valve 7 having an extension 8 adapted to slide within a cylindrical opening formed in the casting 1, this relief-valve being normally held in the closed positionby a coil-spring 9, as shown in Fig. 3. If at any time, air does not enter the collector with sufficient freedom, the relief-valve 7 will be automatically opened by the suction of the exhauster act-- ing through the passageway 5, so as to allow air to, enter freely into the air-outlet 5. The upwardly-extending tapered portion of the casting 1 forms the support for the dustcollector. The latter consists of a receptacle having a cylindrical wall 10 of sheet-metal secured at its lower end to a dome-shaped sheet-metal end-piece 11, which is secured to a flange 12 formed upon a sleeve 13. The interior of this sleeve is tapered to correspond with the taper of the wall 2 of the outlet passageway, so' that when the sleeve 13 is lowered upon the wall 2, a tight working fit is made which precludes the passage the holes 6 from the collector to the air-- I outlet passageway.

' venient. But

for the incoming air as shown, the velocity Secured to the sleeve 13 is a sheet-metal pan 17. having a reinforcement 18 made fast inside it through which a tube 15 extends, the tube being securely fastened to the part The lower end of tube 15 extends below the part 18 and serves to center the pan 17 in sleeve 13 whilethe screws or bolts 19 draw the parts firmly together. On this downwardly-projecting end of the tube, is a gasket 16 of rubber or other suitable compressible material, which, when the collector is mounted upon the support 1, engages the upper face of the'support 1 to prevent dust from entering between the top of base 1 and the under side of sleeve '13.

' It-will be noted, particularly by reference to Fig. 3, that the passageway for the incomingair through the base casting 1 is enlarged in cross-section in its passa e through that casing so that its inner en where it I connects with tube 15 is substantially larger than its outer end. By reason of this con-- struction, the air passing through this passage is diffused and its velocity decreased so that the particles of dust carried by the air will not strike against the walls of the col-' lecting device with too great force. lVe have ound in practice that if the particles of dust enter the collector at too great velocity, they will be carried into contact with the walls of the collector with'such force as to adhere thereto and build up thereon, with the result that emptying the collector of dust would be made more difficult and inconby enlarging the passageway of the air is so decreased that this will not occur; instead the particles on issuing from tube 15 will drop into the pan 17 directly or will hit the walls of the collector with so much less force that they will not adhere but will then drop into the pan. The incoming air is strained of dust and dirt by a strainer 20, consisting of a closely woven fabric. The space withinthis strainer is of very 'large cross-sectional area as compared tothe area of the passa eway for the incoming dust-laden air, so t at when this air issues from that"'passageway its velocity will be furtherand very materially decreased. Itwill be seen that the pan 17 approaches in diameter the diameter of the cylindrical wall 10 of the collector, and the straining material 20 -lies"close to' the cylindrical wall 10. This strainer20 is secured at its lower edge to the upper end of the pan 17 and extends upwardly therefrom to the'top ofthe cylindr cal wall 10, where its edge is secured to that wall. The upper edge of the-wall 10 is strengthened in any suitable manner, as by turning it over upon itself; preferably let passageway 5,

been collected, it is on the cylindrical wall 10, and'the metal of that wall is turned over this ring as shown at 22, to rovide a rounded and reinforced upper e ge. The material of the strainer 20 is turned over the upper edge of the wall 10 and is securedthereto by means ofa metallic ring 23.

The top of the collector consists of a sheetmetal member 24, the central portion of which is preferably curvedupwardly, as shown, at'25, to forma deflector for the dust coming into the collector with the incoming air upwardly through the tube 15. At its outer edge, the metal of the cover 24; is turned over to form a housing for a compressible gasket 26 of such size as to coact with the upper edge 22 of the wall 20. Means are provided for securing the cover upon the upper end of the receptacle, this means being preferably carried by a bar which forms a handle for carrying the collector. A wooden handle is shown at 27, extending diametrically across the cover, and to the ends of this handle are secured metallic pieces 28, pivotally supporting latches 29, the lower endsof which are provided with projections adapted to take under the ring 23. The upper ends of these latches are extended laterally and are noted on by springs 30 to force the latches into the locking position. A bracket 31 is secured to the cover 24 and carries a bolt 32, which extends upwardly through anvopenin in the handle 27 and a similar opening in tie laterally extending arm of the latch 29, this bolt serving to limit the movement of the latch. The spring 30 is coiled about the bolt 32 and is under compression between the bracket 31 and the latch 29.

In using the apparatus, the exhauster draws air in through the port 4, the passageway 3.and the tube 15.

Upon issuing from the upper end of tube 15, the velocity of the air 1-s greatly reduced because of the greatly'increased areaof the collector. Such dust as is carried upwardly into contact with thecover of the collector is deflected by the curved surface 25 and drops into the an 17. The air moves radially outward rom the tube 15 to the fabric 20, which, because of its close weave, strains the air of all of the dust carriedthereby, and this dust falls into the pan 17.- The air thus filtered passes down around the strainer, through'the openings 14 and thus to the outand then to the exhauster. hen a substantial uantity of dust has y necessary to gras the handle 27 and remove the entire co lector from its support upon the casting 1, and it willbe seen that this can be done without disconnecting or in anyway manipulating any of the parts of the apparatus;

If desired, two or more of the collectors may be provided for a single completeapparatus, so that when one is removed, full of dust, an empty one may be immediately thereafter inserted in position, in order to pontinue the cleaning operation without de- 'The strainer presents such a large straining area that it may be used for a very considerable period without clogging the interstices of the fabric to such extent as to render the cleaning operation" inefficient. However, when it becomes necessary to substitute a new piece of straining fabric, this may be readily done by removing the ring 23, thus releasing the upper end of the fab-' ric 20, and then detaching the fabric from the upper edge of the pan 17 Having now described our invention, what we claim as new therein and desire to secure by Letters Patent is as follows:
