Application filed March 29, 1915, Serial No. 17,755. Renewed June 23, 1917'. Serial No. 176,630.
To all whom it may concern:
Be it known that 1, CHARLES H. Fos'rnn, citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Re :t'rigerator Drain-Traps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.
My invention has relation to improvements in refrigerator drain-traps; and it consists in the novel construction of trap more fully set forth in the specification and pointed out in the claims.
The object of my invention is to provide a drain trap for refrigerators which may be adjusted to the drain pipe of the refrigerator without the necessity of shifting the refrigerator from its assigned position, such adjustments being especially desirable under circui'nstances where the waste pipe leading to the sewer and which conducts away the water drained from the refrigerator can not be shifted, or where the drain pipe of the refrigerator can not conveniently be brought directly over the collecting basin leading to the waste pipe. Another object of my invention is to construct a drain-trap which can be readily cleaned when occasions therefor arise. The advantages of the invention will be more fully apparent from a detailed description thereof in connection with the accompanying drawings, in which Figure l is a side elevation of the bottom portion of an ice box or refrigerator, showing my invention applied thereto; Fig. 2 is a side view of the trap, parts being in section; Fig. 3 is a combined rear elevation, and transverse section through the axis of rotation of the collecting basin; and Fig. 4. is a top plan of the trap with parts broken away, and dotted positions showing a partial range of action of the oscillating basin.
Referring to the drawings, R represents a conventional refrigerator, and P the lower end of the drain pipe leading therefrom. In the present embodiment of my invention I provide a waste or sewer pipe 1 projecting through and above the floor F, the upper terminal of the pipe being screw-threaded. Passed over the screw-threaded end of the pipe 1 is an interiorly threaded hollow boss or hub 2- of a collecting basin 3, said boss projecting above the upper surface of the horizontal bottom a of the basin, the-bottom 0 having leading therefrom the inclined extension bottom 5 as shown. The bounding walls 'w, '11:, leading from said horizontal and inclined bottoms have their upper edges (2, c, disposed at an angle conformable to the angle between the bottoms a, Z), respectively. Adapted to be deposited over the hub 2 is an inverted cup or cap a whose peripheral walls are spaced from the hub, the cup being raised above the upper surface of the bottom a by the ribs at formed on the interior surface of the cup walls, the ribs pro jecting beyond the edges of the cup so as to form feet or props. The cup when thus supported has. its lower edge disposed below the upper edge of the hub 2, thereby making a water seal, the surface or level of the water permanently remaining in the basin and forming the seal, being indicated by the dotted line w (Fig. 2).
For convenience, the inclined portion of the basin, identified by the inclined bottom 6 with its inclosing walls to may be regarded as the sweep arm of the basin, the basin proper being restricted to the bottom a and its inclosing walls 10. It will be seen from an inspection of Fig. 4, that the basin rotates about the axis of the hub 2 (on the pipe 1) thus causing the sweep arm to os cillate about said axis; and in the event the discharge end of the drain pipe P is out of range or alinement of the waste pipe 1, the basin may be swung around about the axis of the waste pipe until it comes under the pipe P, the water drained from the refrigerator discharging into the trap basin, whence it flows under the cup a and over the edge of the boss or hub 2 into the waste pipe 1. Should the trap at any time need cleaning, the cup or cap 4 is lifted off, whereupon ac cess may be had to the portions of the basin around the boss 2, and little time be consumed in cleaning the trap. Once the trap is cleaned, the cup a is restored over the boss 2, and the trap is again ready for service.
I do not of course wish to be limited to the precise details here shown as they may be departed from without affecting the nature or spirit of my invention. The screwthreaded connection between the basin and pipe 1 is not indispensable, any other suitable connection permitting the basin to rotate, being within the spirit of my invention. The drain-trap of course is not to be considered as restricted in its application to refrigerators.
Having described my invention what I claim is:
1. A drain-trap having a basin provided with bounding walls, a substantially horizontal bottom portion and an inclined bottom portion leading therefrom and forming a sweep arm therefor, a hollow boss sur rounding a discharge opening in the horizontal bottom and projecting above said bottom, and a removable member cooperating with said boss to form a water-seal.
2. A drain-trap having a basin provided with bounding walls, a horizontal bottom portion and an inclined bottom portion leading therefrom and forming a sweep-arm therefor, a hollow boss surrounding a discharge opening in the horizontal bottom, and projecting above said bottom, a removable member oo'ciperating with said boss to form a water-seal, and a fixed hollow member to which the boss may be rotatably secured, whereby the basin may be rotated and the sweep arm thereof adjusted to any predetermined position, substantially as set forth.
In testimony whereof I aflix my signature, in presence of two witnesses.
