Application filed May 18, 1904. Serial No. 208,516- (No model.) i
To all whmn it may concern.-
Be it known that I, DENTON K. SWARTWQUT, a citizen of the United States, residing at Cleveland, in the county of ()uyahoga and State of Ohio, have invented a certain new and useful Improvement in Separating Devices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.
The object of this invention is to provide in an extremely simple form a separating device for use in separating heavier particles from a gaseous or vaporous draft carrying them orbreaking up the draft itself. Thedevice may thus act as a spark-arrester separating the solid sparks from the gaseous products of combustion, as a dust-collector separating the particles of dust from the air-current, as a steamseparator separating the condensed moisture from the steam, as an exhaust head Devices similar in general operation to my structure have been employed in one or another of the arts above referred to, but, so far as I know, there has been no embodiment of the principle in mechanism as simple, direct, and efiicient as that which I have produced.
The essential characteristics of the invention may be best summarized as consisting of the construction hereinafter described, and definitely set out in the claims.
In the drawings, Figure 1 is a vertical central section through my invention embodied in a form suitable as an exhaust-head, sparkarrester, or dust-collector. Fig. 2 is a plan of the structureshown in Fig. 1, and Fig. 3 is a vertical central section of the device adapted as a steam-separator.
In each of the figures, A represents a cylindrical tube forming the body of the separator. Each end of the tube is open. tube, near the entrance end,is a plate B, twisted to form a spiral of steep pitch. This gives a whirling motion to. the fluid, causing the heavier parts to move outward by centrifugal force toward the Wall or bore of the body A.
Carried by the body A, near the exit end thereof, is a tubular annulus, (designated ain Figs. 1 and 2 and a in Fig. 3.) In the former figures the annulus is a separate cap screw- VVithin the threaded onto the body A. In Fig. 3-the annulus is shown as made integral with the body. The annulus is open on its inner periphery, whereby it communicates with the interior of the body A. Beyond this communieating opening the interior Wall of the'annulus extends inward, terminating in a circle a of smaller diameter than the bore of the body A.
tubular member. 1
The. twisted plate B, which may be secured in place in any suitable manner, constitutes a spiral deflector, causing the fluid entering th body at that end to be give .1 a sfifai n. forcing its heavier particles outward, s
when the fluid reaches the exit end of ti...
body these heavier particles, sliding along the bore of the body, as it were, pass directly into the annulus, engaging the reentrant wall there of, which projects within a prolongation of the bore of the body, and sliding along that wall are caught in the annulus, while the lighter particles pass through the exit-opening a. The heavier particleswhich enter the annulus, be they dust, sparks, water, or other material, are removed through suitable exit members.
The exit provided from the annulus for the particles caught therein may be the pipe (J, as shown in Fig. 1, or the chamber C, as shown in Fig. 3. In Fig. 3 this chamber is provided-with a draining-cock c and a glass gage c to indicate the height of the water in the chamber.
The screw-threading of the annulus to the bodyllas shown in Fig. 1, has the advantage that it thus provides-means for adjusting the communicating passage between the annulus and the .body. The entrance endof the body A may have an integral flange for connection,
as shown at a, and the twisted plate B may be cast integrally with the body, as indicated by the drawings.
I claim I A separating device comprising the combination of a tubular body, a spiral deflector therein, a tubular annulus carried by the body near its exit enu, said annulus having an opening communicating with the interior of said body, and there being an exit-opening beyond such communicating opening.
2. A separating device comprising the combination of a tubular body, a spiral deflector therein, a tubular annulus carried by the body near its exit end, said annulus having an opening communicating with the interior of said ady, said annulus beyond said opening continuing inward and terminating within a pro-' longation of the bore of the body, there being an opening through such inwardly-continuing portion of the annulus of smaller bore than the bore of the body, substantially as described.
8. In a separating device, in combination, a cylindrical tube, a twisted plate therein, a tubular annulus carried by said tube near its exit end and having an opening on its inner periphery at said end and having a wall extending inward beyond a prolongation of the bore of the tube, and an exit member leading from said annulus, substantially as described.
4:. In a separating device, in combination, a tubular body, a spiral deflector therein, a tu- BEsTAvAiL'AsLE cos bular annulus in the form of a cap screwthreaded ontothe exit ,end of the body and having an inner peripheral opening communicating with the interior of the body around said end, there being an opening through the end wall of the annulus, and an exit member leading from said annulus, substantially as described.
5. In a separating device, in combination, a tubular body,a spiral deflector therein, and a tubular annulus screw-threaded onto the exit end of the body and having an inner peripheral opening communicating with the interior of the body around said end and having a wall curving over the end to a point within the prolongation of the bore of the tubular body, there being an opening through the end wall of the annulus of smaller diameter than the bore of the body, substantially as described. In testimony whereof I hereunto aflix my signature in the presence of .two witnesses.
