1 l This invention relates to dust bins or dust receptacles, and to containers in which mops may be shaken to remove the dust from the mop and more particularly to dust bins for shaking'dust from mops to avoid shaking the mop out of the window or elsewhere where the dust would be objectionable, though it is noted that in some of the claims'the invention is not limited to dust bins.

Objects of the invention are to provide an improved closure means for the dust bin and to provide automatic means for closing and open ing the closure means. I

Other objects of the invention are to provide improved bafiles within the bin, and improved means for removing the dust from the-bin. Additional objects of the invention are to effect simplicity and efiiciency in such dustbins and to provide'an extremely simple dust bin of this kind which is convenient, durable, clean and reliable in operation, and easy to operate'and economical to manufacture. I H a Still other objects of the invention will appear as the description proceeds; and while herein details of theinvention are described in the specification andsome of the claims, thegin'vention as described in the broader claims is not limited tothese and many and variouschanges mayfbe made without departing from the scope of the invention as claimed in the broader claims. N

The inventive features for the accomplishment of these and other objects are shown herein in connection with a dust bin which briefly stated, includes a container havingfa top wall and a curved sidewall, said top wall having a stationary slot extending inwardly from-theperiphery, said side wall having below said slot a large. opening communicating with said slot.- A rotary plate or disk 'rotatably mounted on the top wall carries anapron engaging'said curved wall and adapted op'ening and the slots-respectively,whereupon-the slot 6 Claims. (01. 15-104) to close or clear said opening'wh'enthe-plate is dle on the edge of the curved slot and the closing of the apron over said opening, whereupon the handle may be shaken to agitate the mop in the barrel to remove dust therefrom. Outward lateral'movement of the mop automatically opening the apron for the removal of the mop.

Gratings and bafiies within the container against which the mop may be used, assist in removing dustand dirt from the mop to be removed from the container as explained hereinafter.

In the accompanying drawing showing, by way of example, one of many possible embodiments of the invention:

Figs. 1 and 2 are respectively front elevation and plan'showing the dust bin in closed posi- Figs-3 and lare respectively front elevation and plan showing the dust bin in open position;

Fig. 5 is a horizontal sectional view, partly in elevation and drawn to a larger scale, showing the dust bin in open position, the section being taken substantially on the line 55 of Fig. ;6, looking in the direction of the arrows of said line; and

Fig. 6 is a vertical sectional view, partly in elevation showing the rear part of the interior of the dust bin, the section being taken substantially on the line 66 of Fig. 5, looking in the direction of the arrows of said line. I

This invention is shown embodied inan automatically closing dust bin for mops, said dust bin comprising a cylindrical bin or barrel l0 having a circular top wall ll (Fig. 6) a cylindrical side wall l2, upper and lower gratings l3, l4 and uncrossed parallel bars I5, Iii-spaced from-the top wall and the bottom plane of -the-barrel re-- -2 I in which the lower part'of the barrel removably rests. A radial outlet nozzle 22 mounted on and projecting from the side wall l2 communicates with the barrel below the lower grating,the wall 2! of the tray havinga cut-away notch 23-receivhandle maybe pushed to the inner end 'of th'e T stationary slot causing the camming of the han-v ing the nozzle. ,The' nozzle is adapted'to receive a a hose 22a establishing communication between .the iriterior of the barrel below the lower grat' ing and the suction of a vacuum cleaner or other. source of. suction for removingthe dust from the barrel. Obviously this nozzle may be omitted, and dust emptied by removing the barrel from the tray and emptying the dust from the tray. The tray bottom may be secured to the side wall [2 if desired, and the tray wall 2| omitted.

The circular top wall H is provided with a substantially radial slot wide enough to receive a mop handle 26a and extending through the peripheral edge of the top wall and extending near and offset from the center of the top wall. The side wall I2 of said barrel has below the outer end of the slot 25 a large opening 21 (Figs. 3 and 5) in the front part of the barrel, large enough to admit the mop 26 and extending to near and below the top wall to provide an upper strengthening flange 28. joining the.

top wall and having an upper vertical slot extension 29 communicating withsaid slot 25iand large enough to admit the mop handle Ma-to.

said slot 25.

A pivot pin, eyelet or rivet 30', secured in the center of the top wall rotatably receives. a- 118-. ripherally projecting rotary disk 3| on the top wall. and having-a central-opening rotary on said pin 30. The disk 3-! maybe cut away at the chain line. 32, or otherwise designed, to save material.

Said disk 3| carries a closure apron secured on the'periphery of said disk and enga ing the side face of the barrel and adapted to completely close said large opening 2"I- when the disk and.. apron. are. in one position of rotation shown-in. Figs. 1, Zand. 5.and.to clear said opening. which the disk] and apron are in-a second andopen position of rotation asshown in Figs. 3 and 4. Said disk is provided with an at least partially curved or spiral slot '36 wide enough to. receive the: mop handle; 26a and having its inner end registerable with the inner end of the slot 25. when the disk and apron are in closed position as in Fi-g. 2 and having itsouterend registerabl e-with the outer end of thexslot 25 when the apron and disk. are; said second. and open. position, asshownin Figs. 3 and 4, whereby said outer ends mayreceive the mop handle 26a, whereupon the handle 2611. may be pushed to the iinner end of the slot 25 causing an edge of thecurved or. spiral slot 36.- to cam o n the handle'until; the handle reaches the inner end oft-heslots, causing partial rotation of the disk and registration of said inner ends and theclosing of the apron,35:- over said large opening 21, whereupon thehandle 250, may be shaken to agitate the mop '26 in the barrel to remove dust thereirom;while the dust isconfined in the barrel by the apron and disk, and isfree to drop through the grating I-4---tothe lower part of the barrel-to be drawn through the nozzle into. the hose Zimconnected to; the suction of a vacuum cleaner or, to -be emptied by removal of the. tray 20,; .or otherwiseremoveda V niterthe dust has been removed-from the: mop, outward movement of theghandle 26a to. theperiphery of the top wall; ti again causes'registration ofssaid-outenendsrofithe slots 25,. 36, thus opening-the front opening 27.- and allowing. removal of the mop.

A guide strip: 3:9 is secured around the side wall Just-below the large opening andhaving its per. reinslightlv.out dly ofi-set to P videa track-groove .49; lowenelige ofthe apron 3.5 slides' andis; guided;

(Fig; 5) in. which the anda-Estop. strip ,4 l' securedto. the. sidewallgnear .feetiongthe foot; restsfih.

its margin nearest the opening off-set from the side wall to provide a keeper groove 42 in which the adjacent edge of the apron is received and stopped when in closed position. Said strips 39, 4| serve to keep the apron securely closed when the mop is being agitated in the barrel. A stop bracket 43 is secured on the outer face of the barrel in position to stop the apron in fully open position.

A half-sleeve M large enough to receive half of, and guide, the mop handle has a lower outturned flange 45=secured to thedisk around the inner end of the. spiral slot and :positioned to allow the sleeve to be substantially coaxial with and to engage and guide the mop handle just out. of. contact with the inner end edges of the slots. Downwardly projecting horizontal spaced strengtheningbars 46' of angular cross-section are secured to said flange 28 and said top and .side walls, for strengthening the top wall.

' Inwardly projecting parallel spaced arcuate bafiles 46?:0f round cross-section are mounted on brackets 41 secured to said side wall, the baffles terminating at'said large openingZ'l. Saidbafiles 46. andgratings l3, l4 facilitate removalof dust from. the mop. when the latter is beat and rubbed against the baffles and gratings. The upper grating I3 serves, to protect thetop wall.

A pair. of, plate-like. foot rests 4.8 secured. to the. lower part of the tray and. projecting tollie flat on the. floor or other. support supporting the tray are adapted to be stepped on by the oper ator, for holding. the barrel while the mop is being manipulated or when the barrel is removed fromthe tray; and handles 49v inv the side of. the barrel facilitate handling the. dust. bin and re.- moving. the barrel from thegtray.

The various parts o-f the: dustbin maybe held together-by welding, soldering or in anysuitable known manneri I The operation of the dustbin will be; easily understood from' the foregoing, and is. now only briefly summarized as follows; 5 l,

With the bin. assembledin. o-pen,p,ositionifas in Fig. 2, the operator merely places the mop to be. cleaned approximately .in the. position of the dottedlines of Fig. 6 withflan intermediate part of the handle in theeregistering outer. ends of the slots 25 and36 and the, space 50 (Fig.5) between the, ends: of the interrupted ring. Then the. upright handle is forced inwardly to the innerendsof the slots '25, 3.B. .and between adjacent bars l5a. of: the upper-grating, thebars 1511 beingparallel to; the slot 25, and connectedby a curved-cross bar 5! just.beyend-- the innerv end of the slot 25.; The stated. inward movement automatically: closes. the apron 35..

The monZB-and handle are then agitatedand shaken up and down and-aroundat the; same time; hitting and rubbing the mopupon the uncrossedgrating bars l5t-and I6 andEbaiiles-AB, to remove thedust, and dirt a-nd allowvtl'lemto fall within the tray. 20 tc beremoved as: hereinbeforastated. Afterwards; the-mop handle .is drawn to the outer ends ot; the slots, 2.5, 3.6,; thus automatically removing the aproniiromthe opening 21-, allowing removal ofthemop.
