AlR-SEPARATOR FOR HYDRAULIC SYSTEMS.

SPECIFICATION forming part of Letters Patent No. 580,169, dated April 6, 1897. Application filed October 15, 1895- Serial No. 565,812. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM DEH. WASH- INGTON, of New York city, in the county of New York and State of New York, have in- 5 vented sundry new and useful Improvements in Air-Separators for Hydraulic Syste'rns, of which the following, taken in connection with the accompanying drawings,is a specification.

This invention relates to air-separators; and it consists of certain improvements in the construction thereof, as will be hereinafter fully described, and pointed out in the specification and claims annexed thereto.

This invention is illustrated in the accompanying drawings, as follows:

Figure 1 is a vertical section on the line 2 2 in Fig. 2. Fig. 2 is a vertical section on the line 1 1 in Fig. 1. Fig. 3 is a vertical elevation of one of the separating or stirring pipes with its accompanying fingers.

This device consists of a tapering shell or case A, having an inlet-opening a and an outlet-opening 6, larger than its inlet, the ridges or riftles O, the depending vanes or wings D, and the air-opening d d, &c., the collecting-chamber B, and the separating or stirring pipes K, provided with the fingers k. Preferably these parts, with the exception of the separating pipes or fingers, are cast integral with the case A, as shown, but not necessarily so. This tapering shell or case is connected by its larger end to a settlingchamber E, which may be of the form shown or of any other preferable form. This settling-chamber is provided at or near its bottom part with an outlet 6 to the hydraulic machinery with which it is to be connected. The inlet-opening from the taper-case A is preferably so located as to have the horizontal center of the clear opening between the top of the rifiies O and the bottom of the wings D slightly above the top of the opening e, above referred to. The upper part of this chamber E is prolonged to. a sufficient height so as to form an airreservoir for holding the accumulated air brought to it by means described farther on until it can be properly drawn olf or emptied through the opening e, preferably located near the top of 0 this chamber. At or near its top is a manhole provided with a flange cover, to which may be connected the air-pipes f, which will be described farther on. The smaller end of the tapering case A is connected to the suction-pipe B. At some point in the upper surface of this suction-pipe F, preferably a distance equal to two or three diameters of this pipe, may be located one or more wings or vanes D, depending from its upper surface and which may be inserted therein or cast integral therewith. The lower edges of these wings or vanes, both those located in the suction-pipe F and those in the taper-case A, before referred to, curve toward the direction from which the liquid being handled is approaching. At the highest point in the upper surface of this suction-pipe F and the case A, before referred to, and on the side of these vanes or wings next to that from which the liquid being handled is approaching are holes d d, &c. These holes are connected to vertical air-pipes g g, &c., rising to a height equal to the top of the settling-chamber E. All of these vertical pipes g g, &c., are joined to and connected with a horizontal pipe f, which is preferably connected to the flange on the top of the settling-chamber E. Located near the smaller end of the tapercase A are a number of small pipes K, provided with the fingers 7c and having the inlet openings j on the opposite side from which the liquid being handled is approaching. The upper ends of these pipes K are connected with the chamber B, which is situated on top of the case A and which may be cast integral with it or fastened to it by any suitable means. From the highest point of this case or chamber B one of the vertical pipes g leads to the suction of an air-pump or other means of abstracting the gases, or it may be connected to the horizontal pipe f, before described. The small fingers it project from opposite sides of these pipes K and at right angles to the longitudinal axis of the case A.

0n the bottom surface of the tapering case or shell A are located ridges or riffles O, which may be of any desired number. These riffles are of such shape and are so located in reference to their corresponding vanes D that any air or other gas which may be contained in the liquid being handled is liberated by the eddy formed by such liquid in passing over the riiiies O and is caught by the advancing edges of the vanes D.

The tapering case or shell permits the volume of water to expand as it enters the same and decreases its velocity, so that the gases contained therein are readily liberated by the action of the ridges or riffles located in the shell, as the water when in its expanded state and under reduced velocity allows the gases to escape more readily than otherwise.

The action of this apparatus is as follows: Any air or other gas which maybe contained in the liquid being handled is first caught by the advancing edges of the vanes D in the suction-pipe F. Any further gases which pass these first vanes are liberated and separated by the fingers 7c, projecting from the pipes K, and may pass up through the openings j in these pipes and be collected in the chamber B, or may be liberated by the eddy formed by the riffles 0, just described, and be caught by the advancing edges 'of the succeeding vanes D, projecting from the top of the case A, passing up on the upstream side of same and conducted by the pipes g g, &c., to the pipe f and thence to the suction-chainber E.

Having fully described my invention, what I desire to claim and secure by Letters Patent is as follows:

1. In the suction of ahydraulic apparatus, a tapering section or shell provided in its lower portion with means for producing eddies in the liquid being handled, vanes on the upper portion of said section above said means .to arrest the passage of the gases so liberated, and means communicating with the upper portion for conveying such gases to a reservoir, substantially as described.

2. In the suction of a hydraulic apparatus, the combination of a tapering shell or section, riflies rising from the lower portion thereof, depending vanes above said rifiies, and means communicating with said section or shell adjacent to said vanes for conveying thegases liberated to a reservoir, substantially as described.

3. In the suction of a hydraulic apparatus, the combination of a section or shell provided with depending collecting-pipes, means for agitating the liquid handled to liberate the gases therefrom, and conducting pipes in communication with said collecting-pipes and adapted to convey the gases therefrom, substantially as described.

at. In the suction of a hydraulic apparatus, the combination of a section or shell provided with riflies upon its lower surface, depending vanes extending downward above said riflies,

conducting-pipes communicating with the upper portion of the section or shell between said vanes, and a reservoir having said conducting-pipes communicating therewith substantially as described.

5. In the suction of a hydraulic apparatus,

the combination of a suction-pipe provided with gas-collecting vanes at the upper portion thereof, an expanding section or shell provided with riftles upon its lower surface and collecting-vanes above said riflies, a settling-chamber in communication with the expandd end of said section or shell, and a gasconducting pipe communicating with the upper portion of said settling-chamber and with the upper portions of said expanding section or shell and suction-pipe, substantially as described. p

6. In the suction of any hydraulic apparatus the combination of a tapering section or shell, A, provided with the depending pipes, K, furnished with the fingers, k, for the put pose of liberating the gases of the liquid being handled, the outlet-openings, d (1, d",

the collecting-chamber, B, the air-pipe, and air-pipe f and air-chamber E and means for abstracting the gases so collected, substantially as described.

7. In the suction of any hydraulic apperatus the combination of a tapering section, A, provided with the riffles, O, the depending pipes, K, the depending vanes, D, the outletopenings, cl d, &c., the air-pipes, g, g, 850., the air-pipe, F, and a settling-chamber, E, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 1st day of October, A. D. 1895.

WILLIAM DEH. WASHINGTON.
