STEAM-TRAP.
Specification of Letters Patent.
Iratented. May 1, 1906.
Application filed February 24, 1905. Serial No. 247,071.
To (til whom, it may concern:
Be it knownthat we, CHARLES E SQUIRES and BENJAMIN F. SILLIMAN, citizens of the United States of America, and residents of Cleveland, county of Cuyahoga, and State of Ohio, have invented certain new and useful improvements in Steam-Traps, of which th following is a specification.
Our invention relates to improvements in contrivances provided to automatically expel condensation from steam-pipe lines or steam-pipe systems.
The object of our invention is to render such contrivance equally as well adapted for high and low pressure service. We attain this object in an apparatus constructed and equipped as shown in the accompanying drawing, which represents a vertical sectional view of said apparatus.
Like letters of reference denote like parts in the drawing and specification.
- The chief feature of this invention consists in the valve-releasing mechanism, whiclrenables a ready discharge of the condensation in the trap regardless of the prevalent steampressure within such traps. In the main this steam-trap comprises the vessel part A with lid B, the bucket C, the valves D and E, and a suitable bonnet, cage, and cover, reference to which is had hereinafter.
' The vessel part A has its steam-inlet at a, and opposite therefrom is located the lid B, which in any suitable manner may be held in secure connection with said vessel.
A drain for the sediment is shown at l).
About centrally near the bottom of the vessel is pivotally suspended the bucket C, as at c. The bucket 0 consists of a thin metallic structure and carries in hinged connection the stem. at for the valve 1). The latter is thereby raised and lowered, according to position and condition of said bucket-that is, when or as long as said bucket is in buoyant condition the valve E is held closed against the opening 0 by and through the intervention of valve l) and stem d.
from opening e to admit of a free discharge of the water within the bucket, the water being forced out by the steamressure which is prevalent Within the vesse above the waterline, and upon discharge of sutficient water the bucket will again ecome buoyant and raise the valves D and E to hold the discharge-openings closed as long as the waterline in the vessel is below the edge of the bucket.
As shown, the bonnet F is secured to the top of, the vessel, and the tube f depends therefrom well nigh to the bottom of the bucket.
On top of the tube or face of the bonnet F is secured the cage H and cover I in any suitable manner, there being a space left between said cage and cover and a chamber hvbeing formed in the bonnet in order to establish open relation with outlet g, wherefrom the water is conveyed to the sewer or some other place, tank, or the like.
It is preferred to make the cage a separate part from the bonnet simply for convenience of construction and ease of accessibility. Within the cage is formed asuitable guide it for both the valves D and E, Same is centrally suspended from. the inner wall of cage ll, leavingopen relation from the entrance 4. to its outlet c.
When the valve D is forcing the valve E toward its seat 6 at the entrance of opening c, then pressure will immediately exert itself on the under side of said valve and hold same tightly against its seat, and were it not for the opening in said valve the latter would not recede, even though the stem. d would be withdrawn by the sinking of the bucket. By way of the opening though, the pressure under valve E becomes released, and the latter will at once ali'ord tree exit for the water through the outlet c, l'rom where it reaches the discharge branch g, as above stated.
' From the foregoing it can readily beseen that by providing a relief-valve in connection I with the main valve any desirable discharge 1%. very through said tube,-a valve-cage with top outlet secured on top of said bonnet, an apertured cone-valve seating against the top outlet, guided in said cage and furnishin a seat for said rod-Valve as shown and for t e purpose set forth.
In Witness whereof We have hereunto set out hands this 18th day of February, A. D. 20
