DUST-ARRESTER.
Specification of Letters Patent.
Patented July 4., 1916.
Application filed April 21, 1916. 7 Serial No. 92,789.
To all whom it may concern:
Be it known that I, GEORGE W. GLAss- FORD, Sn, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Dust-Arresters, ofwhich the following is a specification.
This invention relates. to dust arresters of that type having a gang of screens located wit in a casing, with means to jar the screens to dislodge dust therefrom, and the improvements relate particularly to the manner in which the screens are constructed and in which they are supported in the casing. a i
The invention is illustrated in the accompanying drawings in which:
Figure 1 is an end elevation of the casing, partly in section. Fig. 2 is a vertical cross section, showing one of the screens in elevation. Fig. 3 is a side elevation of one of the screens, partly broken away. Fig. 4 is an edge view of one of the screens. Fig. 5 is a detail thereof in section.
Referring specifically to the drawings, the dust arrester house or outer casing is indicated at 1, constructed of proper size and shape to inclose the parts hereinafter described. This has an outlet chute 16 at the bottom. Part of the inner wall of the top consists of tongue and groove stuff as indicated at 1 forming a roof for the chamber above the screens, and 2 are strips of canvas or the like extending between said roof and the upper edges or corners of the gang of screens, these strips being held in place by wooden strips 3. This forms a chamber above the screens, with flexible sides permitting the screens to vibrate, and forming a dust tightv connection which prevents dust from settling on top of the screens.
Each screen unit comprises a frame comis provided with strips 141 with a space therebetween to hold felt packing 15, providing a tight joint between the head frames, and these frames have openings as indlcated at 30, which communicate across the gang, leading to an outlet 31 for the clean air.
The screen cloth 9 is supported and prevented from collapsing by wires 7 stretched between the head frames and the bottom piece 10 and these wires are spaced apart by blocks 8 to which the wires are attached by staples 18. The screens are secured together in a gang by bolts 24 extending through the head frames 12', which are set into rabbets in the upper ends of the end pieces 10.
The gang of screens rest at their lower ends on cross bars 40, above the chute 16. At one end, each screen is provided with a piece 13, to which are fastened cross strips 25 on which are mounted bearings 26 for a shaft 27 which has cams 28 arranged to strike the bars 50 of hammers 29, these bars being pivoted at the bottom at 51. Springs 52 are connected between the hammers and the ends of the screens, and act to return the hammers after they are swung out by the cams, and on the return stroke the hammers strike leather pads fastened to the cross frame 25, thereby jarring the screens.
34 is an inlet to the outer casing, and between this and the gang of screens is a shield 36 which extends across the casing, being held by supports 35, and acts to protect the screens from the impact of hard or lumpy sediment or particles which enter with the dusty air.
The openings 30 at the top of the screen may be made any size desired, according to the size of the outlet pipe connected therewith, and the size may be varied by an appropriate change in the pieces forming the head frames '12 without aifecting the area of the screen cloth surface, these head frames being as shown at the top of each unit and extending completely across the same.
In operation the dusty air entering through the inlet 34 is deflected by the shield 36, and passing around the same is drawn through the cloth at the sides of the screen units, the clean air flowing upwardly therebetween to the head frames and thence through the trunk openings 30 to the outlet. The screens are jarred by the hammers in an obvious manner. Vibration of the screens is permitted by the flexible strips 2 which connect the screens to the roof, and
these strips prevent dust entering above and lodging on top of the units. The ability to use head frames having openings of different sizes, without varying the dust collecting area or surfaces, is highly advantageous in the practical erection of the arrester, 1n order to suit the same to local con ditions.
from the top downwardly, and provided with head frames secured to the side wall of the casing, said head frames extending across the screen frames from the front to the back thereof and fitting side by side against each other and having registering lateral openings communicating with the said outlet opening. I
3. A screen for dust arresters, comprising a screened frame provided with sides converging from one end to the opposite end, and head frames on opposite sides of the said frame at the wide end thereof, said head frames extending entirely across said wide end and having lateral openings.
4. A screen for dust arresters, comprising a frame consisting of top and bottom pieces, and end pieces tapered downwardly, screen fabric on opposite sides of said frame, and head frames extending across the top of said frame, at opposite sides thereof, from one end piece to the other, said head frames having lateral openings.
In testimony whereof, I do aflix my signature in presence of two witnesses.
