UNITED; STATES PATENT: OFFICE J'OSEPH A'BRAMOWITZ, OF MADISON, ILLINOIS, .A SSIGNOIR. OF THIRTY-FIVE PER GENT TO AMANDA E. KING, OF MADISON, ILLINOIS DUST-COLLECTOR 7 Application filed August 20, 1928. Serial No. 300,731.

This invention relates generally to dustcolleetors and, more particularly, to a certain new and useful improvement in dustcollectors especiall adapted for use in connection with shoenishing machines and the like.

Modern day practice requires, from the standpoint of health and fire prevention, that machines, such as shoe-finishers and anal-' ogous structures, be equipped with dust-collectors, and my present invention has for its object the provision of a dust-collector especially adapted for the purpose, the dust-col- =lector being of inexpensive construction,

readily and conveniently installed in connection with the machine, and eflicient in the performance of its intended functions.

And with the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combination of parts hereinafter described and pointed out in the claims.

In the accompanying drawings, sheets) Figure 1 is a reduced perspective View of a shoe-finishing machine equipped with a dust-collector embodying my invention;

Figure 2 is an enlarged plan view, partly broken away and in section, of the dust-collector; and

Figures ' 3 and 4 are. sectional views of the dust-collector taken, respectively, on the lines 3-3 and 4-4, Figure 2. w

Referring now more in detail and by reference characters to the drawings, which illus- (two tion, A designates the dust-collector, which is preferably in the form of a box-like shell or casing of suitable sheet metal, shell A comprising a base or bottom wall 1 afront wall 2, a rear wall .3, and side walls 4, 4, suitably crimped or clinched or otherwise pere manently joined together in operative relation.

At'their upper margin, the rear wall 3 and side walls 4 are bent upon themselves, as at 5,

to provide a slide or guide-way for a prefer- 'abl shiftable closure top wall or lid 6.

djacent its upper mar 'n; the rear wall 3 isformed with a prefera 1y circular openchine ing, as at 7, in which isdisposed a tubularconnection 8 for the discharge end of a dustconveying conduit 9. Disposed within the shell A and suitably fixed at one end, as at 10, to the rear wall 3, is a tubular-member or flue 11, which at its said fixed end 1Q encircles the projecting inner end of, and communicates with, the pipe-section 8. A From said rear wall 3, the flue 11 extends forwardly into the shell A, tapering somewhat in diameter from its rearward to its forward end, and at its forward end is provided with a relatively short downwardly presented extension 12.

Dispose within the shell A and suitably fixed, as at 13, to and upon its opposite side viding a support for a shiftable tray 15 slidably removable relatively to the shell A through an opening 16 provided for the purpose in the shell front wall 2. The tray 15 is substantially in the form of a frame having its walls disposed parallel with the upstand ing walls of the shell, the bottom wall 17 of the tray being of mesh material or otherwise formed with a multiplicity of' perforations. The shelves 14 are so located within the shell that the tray 15 is disposed normally in a lane intermediate the discharge end of the ue-extension 12 and the shell bottom .wall 1, the frame of the tray beingprovided at its forward end with a plate-section 18 adapted to form a closure for theshell front-wallopening 16, and which is preferably equipped with a handle 19 for facilitating removal and replacement of the tray,

My new dust-collector is, as I have stated,

especially adapted for use in connection with shoe-finishing machines and the like, B desig- 'natinga shoe-finishing machine of standard, construction. Leading from the machine B, is the dust-conveying conduit 9, whichconnects and communicates at its lower end with the pipe-connection 8, a suction-fan or the like, not shown, being suitablyassociated with the conduit 9, for purposes-shortly ap-' pearing. Communicating at one end with the conduit 9 and havingcommunication inter nediateits ends, as shown, with the several bufiin%and grinding is a pipe or devices 6 of the ma ufe 20 providedwith an '100 ;B, the dust or the like created by the devices b will be sucked from the pipe 20 and blown through the pipes or conduits 9 and 8 into the shell, the extension 12 deflecting the same downwardly on to the tray 15. At the same time, the spray from nozzle 23 dampens or Wets down the incoming dust particles and the like, thereby not onl preventing combustion, but settling the dust particles upon the mesh-bottom of the tray 15, surplus water finding escape through the tray mesh-bottom 1.7 into the shell A, from whichit may be suitably removed through a drain 25. The incoming dust-laden air is thus freed of its carried dust-particles and the like, the pumfied air finding escape through the opening 22 and pipes 21 and 20 backto the conduit 9 for further utilization, and the tray 15 bein readily shiftable from the shell A at suitab 6 intervals for removal of accumulated matter. A bafile 26 depending within the shell A facilitates exhaust of incoming air through the opening 22 and into the conduit 21.

My new dust-collector thus functions handin-hand with the machine and accomplishes V as described the objectsand purposes stated.

It is to be understoodthat changes in the form, construction, arrangement, and combination of the several parts of my dust-collector may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

' Having thus described my invention, what I claim and desire to secure by Letters Patcut is: v

1. In combination, a dust-collecting shell having an opening in a wall thereof, a flue dis osed and fixed at one end within the shell an at its inlet end surrounding said openin a discharging extension disposed at an ang e to and presented downwardly from the flue,

a dust-conveying conduit having communication at its discharge end through said opening with the flue, means for spraying and wetting down the incomin dust, and a receptacle within the shell or receiving the matter discharging from said extension.

2. In combination, a dust-collecting shell having an opening in a wall thereof, a flue dis osed and fixed at an end within the shell an at its inlet end surrounding said openin a" discharging extension disposed at an ang e at its inlet end surrounding said opening, I

a discharging extension disposed at an angle to and presented downwardly from the flue, a dust-conveyingxconduit having its discharge end projecting t rough said opening and into said flue, a nozzle disposed in said conduit adjacent said opening for spraying and wetting down the incoming dust, and a meshbottom tra supported within the shell for receiving t e wetted down dust discharging from said extension.

4. In a dust-collector, a shell having an openin in a wall thereof for communication with a list-conveying conduit, a flue disposed within the shell and-having its inlet end in communication with said opening, an extension upon the flue having its dischargeend presented downwardly from and at an angle to the flue, and a shiftable mesh-bottom tray removably supported within the shell intermediate the bottom wall thereof and the discharge end of said flue-extension.

5. In a dust-collector, a shell having first and second openings in'its walls, the first opening being adapted for communication with a dust-conveying and spray conduit, a flue fixed within the shell and having its inlet end in communication with said opening, a shiftable mesh-bottom tray removably supported within the shell for removal through said opening, the bottom of the tray being spaced from the bottom wall' ofthe shell, an extension fixed upon and disposed at an angle to the flue, said extension having its dischargeend presented downwardly for delivering the incoming matter upon the mesh-bottom of the tray, the shell having an air-exhausting opening in a wall thereof, and a member on the tray for closing said opening.

In'testimony whereof, I have signed my name to this specification.

. JOSEPH ABRAMOWITZ.
