`.Application led April 25,

Our device relates to dust bins and has' for its primary object the reception and retention of sweeping-s and the like, the same being made of metallic sheets having a hinged closure disposed adjacent the front wall thereof and having a bin or chute disposed adjacent to or forming the inner bottom wall of the body element.

The primary purpose and object of our de- ,o vice is to displace or replace dust pans and the lilre and is intended for placingwithini a simplified `construction that may be used' to conduct the sweepings from the various rooms to a central receptacle that may be disposed within the furnace or within the basenient of the house or building in which the same are being used.

A further object of our invention is to provide a means that will speed up the sweepthe use of dust pans and'wherein the sweeping refuse may be deposited within a suitable receptacle or collected at a central station.

lilith these and incidental objects inview,

i the invention consists in certain novel fea-1V tures of construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which is hereina fter shown with reference to the drawings that accompany and form a part of this specification.

We preferably form our device of sheet bars for the body 'element 10; VA hinged closure l2 is hingedly supported upon a j ournaled pin V13, vsupported in oppositely disposed ends of the body portion 10. The I5 hinging closure l2 is adapted to being actuated by the 'foot or'handv of thejsweeper or manipulated by the'broomor sweeping irn-` plement. A! locking bar 11i ishinged relative to the side wall about a hinging pin 15. One end 20 of the locking bar 14 passesthrough a slot 16 and protrudes 'therefromso that it may be actuated by any suitable means. VA locking notch 17 is disposedgon the other endA 'of the lockingbar 14. 'The locking bar 14 isA pivoted olf-center upon vthe pin 2l so that the lockingbar rides upon the pin 18 secured `uponthe hinged closurel.v When it is deso that the locking notch 17 catches on pin 21 and by gravity the bar 14 stays in position until a downward pressure is applied to the protruding end 20; the closure then will return to that of the normal closed position through the action of gravity. An arcuate slot 19 is disposed within the side of the body element through which the pin 18 passes. The sides of the body element have lo inwardly extending edges 21B which act as supports for the dust bin 21 which is removably ,disposed upon. the base ofthe bodyy element,; said bin having outwardlyextending iaps 21C which ride on edges 21B.

There a positive closure is desired an actuating-:spring 121A. may `be vplaced about Athe hinging pin 13 to snap the closure 12 shut. Where our device is to be installed in new construction, dust chutesor sweeping chutes 20 lead from the receptacle to a central collector disposed at a convenient .location in the basement or running directly to the-furnace so :u that the sweepings may be collected at a cen- .E trallstation e525 Then it is desired toremove thesweepings 'i f fthe door is -lopened :andth-e bin 21- is removed through the opening as illustratedl in Fig..4. i VVhi-le .the fformof `mechanism herein shown and described isfadmirably adapted to .230 ulllthe obj ects` primarilystated; it is to be gunderstoodfthat it islnotfi-ntended to confine g, the invention tofthe one-'form' of;embo'cli ment herein-shown, as it, is susceptible of embodiment in various formsT Aall comingwithin m35 fthe scope of the-claims whichfollow.
