OF NEW YORK, N. Y., ASSIGNORS OF ONE-THIRD TO THEODOSIA HATCH, OF SAME PLACE.
GREASE-SEPARATOR FOR STEAM-ENGINES.
cSPECfIFICl-L'lIOll' forming part Of Letters Patent No. 447,327, dated March 3, 1891.
Application filed March 31, 1890.-
To all whom t may concern:
Be it known that we, LEVI HUSSEY and ED- WARD MCOANN, of the city, county, and State of New York, citizens of the United States, have invented certain new and useful Improvements in Grease-Separators for Steam- Engines, of which the following is a specification.
The invention relates to a grease-separator 1o for the exhaust-pipes of steam-engines for separating the grease from the exhaust-steam and collecting it for use again.
The object of the invention is to provide a durable device of this character which will effect a thorough extraction of the grease from the steam.
In the accompanying drawings, Figure l represents a side elevation of our improved grease-separator, showing the same connected zo with a pump for drawing off from time to time the grease separated from the steam byl the separator. Fig. 2 is a top view of the separator, with the top plate removed, and Fig. 3 is a detail side View of one of the wire z 5 screens which are employed for catching the grease. Fig. 4 is a vertical transverse' section of said screen; and Fig. 5 is aside View of a separator, showing a modilied construction of the collecting-chamber and discharge 3o device.
Similar letters of reference indicate corresponding parts.
In the drawings, A represents the exhaustpipe of a steam-engine. In the exhaust-pipe A is arranged a separator B, which is composed of a square or oblong casing B', that is closed by a top plate B2. Below the separator is arranged a collecting-chamber C, in which the grease separated from the exhaust- 4o steam is collected. The side walls of the casing B are provided with vertical grooves b for inserting a number of screensD of suitable wire-gauze, which screens serve to some extent as baiiles for retarding the outward flow of the exhaust-steam, said screens forming contact-surfaces against which the exhaust-steam impinges, so that the grease or oil carried along by the same is intercepted andV deposited on the wire screens and con- 5o ducted along the same, together with the steam condensed by this operation, into the Serial No. 345,966. (No model.)
collecting-chamber C. A baffie-disk E is arranged midway between the screens D in the separator-casing B', said baffle-disk being of smaller diameter than the screens and supported by lateral arms e e in a frame E', which is supported in guide-grooves b in the side walls of the casing in the same manner as the Wire screens. The bafle-dislcE serves for the purpose of deecting the ex- 6o haust-steam and causing it to travel around the entire circumference of the same, so that it is distributed equally over the wire-screens and prevented from passing directly in a straight line through the same, whereby the 6 5 middle part of the screens would wear out too quickly, and whereby a more effective action of the screens is obtained.
In the collecting-chamber O is arranged a fioatf, to the upper part of which is pivoted 7o a lever f, that is fulcrumed to lugs at the outside of the collecting-chamber, .said lever being providedI with a balance-weight at the outer end. To the outer end of the fulcrumed lever f is pivoted a connecting-rod g, the op- 75 posite end of which is applied to an arm g of a valve G, which is located in the steamsupply pipe h, Ithat conducts the steam to the steam-cylinder of a pump P below the grease-separator B. 'Ihe pump Pis connect- 8o ed by a suction-pipe p with the collectingchamber O, the pipe communicating with an opening in the side wall of the same, the opening being arranged at such aheight that when a float arrives at a level therewith it will open the valve G of the steam-supply pipe, while when it falls below the said opening it willclose the steam-supply pipe. Oonsequently, when the level of the grease floating on the water of condensation in the col- 9o lecting-chamber C rises to a level with the opening p of the suction-pipe p the float f simultaneously opens the steam-supply pipe and produces the working of the pump P, so as to draw off the grease until the level in the collecting-chamber falls below said opening. By the lowering of the iioat the valve is closed and the working of the pump interrupted. In this manner the pump is intermittently operated for removing the grease loo and waterof condensation, both being pumped into a suitable storage-receptacle, from which the grease is removed for being cleaned and used again.
In the modified construction shown in Fig. 5 no pump is employed for removing the grease, but the pressure of the exhauststeam utilized for forcing the grease through a discharge-pipe g to a suitable storage-receptacle whenever the level of the grease arrives at the discharge-opening in the collecting-chamber, at which point the fioat and its lever will open the valve in the dischargepipe, so as,to permit the discharge of the collecting grease by the steampressure of the steam on the same.
The advantages of our improved greaseseparator are that nearly all the grease carried along by the exhaust-steam is collected, owing to the contact of the steam with the large number of wire baffle -screens, which act like a net for intercepting` the steam and catching the grease carried along by the same, and, secondly, that the grease is collected in the chamber below the separator and removed automatically from the surface of the water of condensation, so as to require no special attendant. From time to time the screens have to be removed for cleaning the same, which is accomplished by removing the top plate of the casing. Then the screens are Worn out, new bathe-screens are inserted, which can be accomplished at a comparatively small expense.
I-Iaving thus described our invention, We claim as new and desire to secure by Letters Patent- In a grease-separator for the exhaust-pipe of a steam-engine, the combination ot a casing, a number of screens disposed therein, and a bathe-disk of smaller` diameter than the screens supported centrally of the casing between said screens, substantially as described.
In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
