DUST-COLLECTOR.
Speciication of Letters Patent.
Fatented Feb. 25, Mig.
Application filed August 3, 1917. Serial No. 184,273.
To all whom t may concern.' l
Be it known that I, WILLIAM J. SCHMITT, a citizen of the United States, and resident of Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Dust-Collectors, of which I hereby declare the following to be a full. clear, and exact descript1on, such as will enable others skilled 1n the art to which it appertains to make and use the same.
The objects of the invention are to provide a simple and efficient and practical form of dust collector, particularly arranged to prevent the entrance of dust with fresh air delivered to a room or building. The invention is also designed to provide means for readily removing the dust collecting screens from the collector, and to so arrange the supportingand vibrating means for the screens that t e said screens can be each selectively withdrawn from the casing of collector without interfering with the position of other screens or inlet pipes or of vibratingv apparatus. The exhaust openings in the several screens and casings are also so arranged as to approximate closely in cross-sectional area the total area of or admission openings in the cloth composing the screens, so as to permit an unobstructed current of air therethrough.
The invention includes the Specific forms of structure 0f collecting screens and casing therefor and the various features of improved and novel structure hereinafter described, shown in the accompanying drawand specifically pointed out in claims. v In the accompanying drawings Figure 1 is a vertical section of the device; Fig. 2 is a vertical elevation of the exhaust side of the casing showing the large exhaust openings in the several screens; Fig. 3 is an end elevation of one screen; Fig. 4 is a plan of one of the vibrating hammers.
In these views A is a frame forming a chamber having a door or removable wall B at one end and an inlet opening C.
Inthe end opposite the door are formed a series of vertical unobstructed openings A.
A discharge chute E communicates with the bottom of the frame and is provided with a valve F through which dust is discharged. p
G G are the dust collecting screens which include frames covered with screen material upon the outer surface of which the dust collects and by means of which it is prevented from entering the air discharge pipe H leading from the separate air chamber I into which the air is drawn from the screens Eby means of a blower not shown or any other convenient vacuum creating means.
Each dust collecting frame is provided with an unobstructed opening G which registers accurately with one of the openings A in the casing A, and which must equal in cross sectional area the area of the interstices through which the air enters the cloth screens.
rIhe frames vGr G are attached rigidly and closely to the rear wall of the casing to form air tight joints therewith by means of bolts J J which pass through clamping plates K K transversely placed across the opening.
Opposite the frames in the casing is placed a door B by means of which cach frame separately can be removed for subv stitution or repair and a door M in the air chamber permits access to the bolts J J when it is desired to attach or remove the frame.
.The forward end of each frame is-supported on a spring N which permits the frame to be vibrated to shake oil'l the dust accumulated thereon when it becomes heavy enough to clog the screen.
This vibratlon is accomplished by means of aset of hammers `O, only one being shown for illustrated purposes, operated by means of cams P which drop them upon the upper edges of the frame. A common rotatin shaft Q operates all the cams. Each screen ame is rectangular at the upper end and formed tapering at the lower end so that the dust will be readily discharged therefrom.
Having described the invention what I claim as new and desire to secure by Letters Patent is, 1
1. The combination with a casing havingV an inlet opening 1n one Wall and a series of elongated outlet openings in its rear kwall and having a large opening in its. front. wall, of an outlet chamber mounted upon said casing over said outlet openings, a series of hollow screen frames within said chamber having corresponding elongated openings registering with the outlet openings in said casing, said frames rigidly and closely connected to said casing, a resilient support for the end Aof each screen opposite its Voutlet opening means for independently vibrating each screen, said vibrating means located above said opening in said front wall opening in a dust collector employing screens.
2. In combination with a closed casing having an opening in its front wall, and a door for closing the same and also provided with a series of outlet openings in its rear wall, said outlet openings being vertically arranged and spaced apart and of elongated shape, an outlet chamber secured to the rear wall of said casing over' said outlet openings, a series of hollow screens positioned in said chamber, each screen provided with an elongated outlet opening in its rear wall registering with one of the outlet openings in said rear Wall of the casing, each outlet opening aggregating in area the areas of the openings in the corresponding screen surfaces, means for detachably securing each screen to said rear wall, each screen tapering at its lower end to permit the discharge of dust therefrom, and a vibrating means positioned above said opening in said front wall, said casing provided withan inlet opening and with' a discharge opening in its bottom underneath said screen.
3. In a dust collector in combination, a chamber having front and rear walls, said front wall having a large opening therethrough, a hollow screen therein secured at one end to said rear chamber wall, said rear chamber wall and screen having communicating openings, the end of said screen opposite its said lopening being free to vibrate vertically, a cam and shaft therefor mounted upon one of said walls above the level of the opening in said front wall and a weight operated by said cam to engage said screen.
4. In a dust collector in combination, a chamber having front, rear and side walls, said front wall having a large opening, 'a closure for said openings in said front wall, a hollow screen therein secured at one end to said rear chamber wall, said rear chamber wall and screen having communicating openings, the end of said screen opposite said openings being free to vibrate vertically, means for vibrating the said free end of the said screen, said vibrating means being located above said opening in said front wall to permit the withdrawal of said screen therethrough.
5. In a dust'collector in combination, a chamber having an inlet opening and spaced outlet openings in its wall, a series of hollow screens rigidly secured at one end of the said chamber over said outlet openings, said screens having each an outlet opening registering with an outlet openin in said chamber wall, resilient supports for the opposite ends of the said screens, a front wall for said chamber provided with an opening through which said screens can be individually withdrawn, vibrating devices for said screens located above said opening in said front wall to permit said screens to be withdrawn` and a removable closure for said opening.
In testimony whereof, I hereunto set my hand this 28th day' of July, 1917.
WILLIAM J. SCHMITT. In presence ofi WM. M. MAMOA, el. MANNING.
