DUST COLLECTOR.

DUST-COLLECTOR.
SPECIFICATION forming part of Letters Patent No. 408,787, dated August 13, I889.
Application filed November 14, 1888. Serial No. 290,852. (No model.)
To all whom, it may concern:
Be it known that I, JOSEPH S. ASH, a citizen of the United States, residing at Canal \Vinchester, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Dust-Collectors, of which the following is a specification.
My invention relates to the improvement of that class of dust-collectors adapted to be used for separating the dust particles from.
the air.
The objects of my invention are to provide a dust-collector of this class which shall be inexpensive and simple in construction, to so construct the same as to greatly facilitate the thorough removal and collection of the dust from a current of dust-laden air, and to prevent the outgoing current of purified or partially-purified air from again mingling with or obstructing the incoming current of dustladen air or the outgoing dust-discharge current. These objects I accomplish in the manner illustrated in the accompanying dra\ ings, in which- Figure l is a side elevation of my improved dust collector. Fig. 2 is a central vertical longitudinal section of the same. Fig. 3 is a plan view, and Fig. is a transverse section, taken in line 00 m of Fig. 2.
Similar letters refer to similar parts throughout the several views.
A represents the outer case of my improved collector, which, as shown, has a cylindrical upper portion and a conical lower portion, the latter having a dustescape opening a in its lower end.
The upper end of the case A is provided with a top plate I), having a small central airescape opening 0 therein.
D represents a spout leading into the upper cylindrical portion of the case A tangentially, as shown.
6 represents an inner funnel'shaped or invertedconeshaped case having its upper and larger end secured to the under side of the top plate b, about the opening 0 and about midway between the latter and the wall of the case A. This internal case c is made to extend downwardly to a point in the lower por tion of the case A, and has an opening in its lower end which is vertically opposite the dust-escape opening a of the outer case.
f represents a third inner case, which, although smaller, has the general form of the case 0. This case f has its upper end secured to the under side of the top plate 7), adjacent to and about the opening 0 therein, and, extendingdownward, has its lower open end vertically opposite and above the bottom openings of the cases A and e.
Formed in the wall of the case c at desired intervals are a number of slotted openings g, which are formed by cutting upright slits in said wall and bending outward the metal on those sides thereof opposite the direction from which the d ust-laden air-current comes, as hereinafter described, thus forming outwardly-proj ectin g lips 71/. This row of slotted openin gs may extend partially or entirely about the case, according to the strength of the air-current used, as may be desired, and is preferably arranged below the level of the spout D. The internal case f is also provided in its upper portion, as shown, with one or more rows of slotted openings 1', having outwardly-projecting lips 70, as described for the openings g. A current of dust-laden air is blown into the outer case A through the spout D in the usual manner. Said. current, being thus made to enter the outer case tangentially, will, by reason of the circular and conical form of the case, be driven centrifugally around the inner case 0, the dust or heavier particles in the current being thereby driven outwardly against the inner surface of the outer case and allowed to follow the same spirally downward and out through the bottom opening a. The air thus cleansed will be directed into the openings 9 of the case 6 by contact with the lips 71., where it will again, by reason of the conical form of the case, be driven centrifugally, the tendency of the particles of dust which may, have been forced through the openings 9 being to follow the inner wall of the case a spirally downwardly and out through the bottom. opening. therein and. the opening a of the outer case. From the case (2- the lightened purified air will be directed. by the lips 71 through the slotted openings '6 of the inner case f, and thence allowed to escape upward and outward through the opening c of the top plate I).
Ashereiubefore stated, the openings ot' the case c are preferably located below the level 5 of the spout D,t-hus preventing a direct draft between the openings 7 and I: (the latter being located in the upper portion of the inner ease f) and allowing time for the separation of the dust from the partially-purified air within the 10 case 6 before its escape through the opening 11.
In case any of the dust particles should be carried into the central case)", they will be allowed to pass downward and outward through the lower ends of the cases.
Although the invention shown in my former patent, No. 387,617, of August 14, 1888, dustcollectors, shows two internal cases, it will be observed that the internal cases of my present invent-ion diiier in form and construction. The conical form of cases herein shown has been found of great value in practice, while the simplicity of construction greatly decreases the cost of manufacture.
Practice has demonstrated that a current of dust-laden air driven through the almve-de scribed collector thormighlyeleanses th e same.
I am aware that a conical perforated cylinder has been inelosed within a similarlyshaped imperforate cylinder, and that the same are )rovidcd with an inlet-spout, bottom dustescapc openings, and top air-eseape openings, and therefore do not claim, broadly, such construction.
Having now fully described my invention,
what I claim, and desire to secure by Letters
