DUST COLLECTOR oacHU'rE.

Specification of Letters Patent. y Patented A1)1.25,`1922.

Application led February 18, 192.1. jSerial No. 446,031. l

.. whereby the dust and dirt may be swept thereinto from the floor, the .opening being provided with a closure, and the chute being also preferably provided vwith a4 receptacle Yin another part of thebuilding for receiving the dust and dirt, and which receptacle is adapted to be removed when desired.

To the attainment of these ends and the accomplishment of other new and usefulobjects as will appear, the invention consists A inthe features of novelty in substantially the construction, combination and arrangementof the several parts hereinafter more fully described and claimed and shown in the accompanying drawing illustrating this invention, and in whichligiire 1 is a vertical, longitudinal sectional view showing the chute in position within a wall and constructed so as to receive dust and dirt from a' plurality of floors at different elevations. l

Figure 2 is an enlarged detail sectional view vof the entrance end of the chute. y Figure' is an enlarged view partly in front elevation and partly in section.

Figure 4 is a detail perspective view vshowing the position of the chute.

Referring more particularly to the draw-v ing the numeral 10, designates the outer wall and 11 the space within the wall and' in which space the chute or collector is arranged.'

12 designates a chute of any desired size and configuration,preferably constructed of some thin metallic substance and may be -held in position in any desired or suitable manner such as by means of fasteningxdevices (not shown) which may pass through vany of the walls of the chuteto engage a suitable support or anchor. l

Vvln the form of the invention herein shown this chute is arranged to extend for a considerable distance within the wall so as to receive the dust and dirt from a plurality of superposed floors.

The chute is provided with an entrance opening adj acent each of the floors 13414e- 15, 4and these entrance openings are on a line with the floor. Y

The chute is preferablyiprovided with a Closed top 16 and a plurality Of Partitions 17--18 dividing the chute into a` plurality of passages 19-20-21. Each of these pasf sages communicates with the respective inlet opening adjacent the respective floors 13- 14e-15sothat the dust and dirt swept into the passage from anyone of the floors will not be discharged into the passage leading from Vthe neXt lower floor and thisl will thereby prevent the dustand dirt frombeing de liveredto theV floor'below ythrough the en-j" trance opening of fthe chute.

' The top ofthe partition 17, is preferably deflected as at22, so as to be in alinement with. the top of the floor 13, while the top of' the partition 18, isdeflected as at 23, for a similar purpose. A n

' The front wall'24, ofthe chute `adjacent the upper inletgopening is deflected as at 25, so as to project beneath the floor 13, to assist in holding the chute in position. The portion-of the wall 24, adj acent' the inletv opening at the floor line 1,4, is also deflected as at 26, to project beneath the floor while theportion of the front wall 24,'adjacent the-openiing at the floor line 15, is deflected as at 27, to standflush with the top of the floor 15.

It will thus be seen thatwith this construction and whenthe dirt is swept into the chutejfrom any floor it will be conveyed through the respective passages to be deliv ered preferably to a'receptacle 28, which is removably. supported within the chute adjacent the bottom thereof and intojwhich 'chute the passages 19-201-21vdischarge`."

A hood-like member 29 is provided'for each of the inlet openings of the chute and as the construction of each of these members is the "same the descriptionof one will apply equally as well to them all.

This member 29, is provided with an open rear end 30, having slots 31, in the side wallsH thereof and which slots openthroughv thev end 30.

Therfront of the hoodis open as at 32, and v i ceptacle 28.

posite sides thereof are guides 34, and these guides are Hush with the floor lineso that,

when the hood 29 is inserted into the inlet opening of the chute the front end of the hood Will rest upon the floor and the head Will be supported by the guides 34. Fastening devices 35, are connected with the Wall of the chute and project into the openings 3l,.as the hood is placed in position. Co-operating with the fastening devices 35, are thumb nuts 36, which are accessible from the inside of the hood so that when the hood is in position and the flange 3l abuts the outer face of the wall lO, the thumb nuts .36, may be adjusted to clamp the hood in position and thereby hold the flange 33 against the face ofthe Wall. This will obviate the use of fastening devices on the outside of the hood and will also permit the hood to be readily removed and placed in position When desired. Y

A closure 37, is provided for-the open end 32,? of the hood and this closure is preferably pivot-ally mounted as at 38, and is providedwith a handle 39, means of Which the closure may be swung about its pivot. As a means for normally holding the closure in a closed position, :suitable springs 40, may be provided. In use, when the dust and dirt` has been gathered at a point adj aeent the closure 37, the latter may be opened and the dust and dirtsweptinto the chute-so Vthat it Will drop through the respective passages into the rel/Vhen the closure 37, is released ythe springs .a0-Will close the saine.

lVith this improved construction it Will be. manifest that the samey may4 be` readily applied to any buildingl vhaving a space Within its Wall and when applied the necessity of exterior fastening devices Will be obviated. Obviously the chute may be constructed to accommodate any desired number of floors.,

`While the lpreferred form of the invention hasfbeen herein shown and described, it is y to be understood that various changes may be made in the details of-construction and in thecombination andarrangement of the several parts Within the scope of the claims, Without departing from the spiritof this invention. f
