WILLIAM H. HEIDIiIANN, OF EAU CLAIRE, WISCONSIN.
DRAIN-TRAP.
Application filed April 25,
To all whom it may concern:
Be it known that I, WILLIAM H. HEID- MANN, a citizen of the United States, and resident of Eau Claire, in the county of Eau Claire and State of Wisconsin, have in vented certain new and useful Improvements in Drain-Traps; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention relates to new and useful improvements in drain traps for various purposes.
It is in general the object of my invention to simplify and otherwise improve the structure and increase the efiiciency of devices of this character, and it is more particularly my object to provide a drain structure in which is incorporated a valve for preventing retrograde flow of fluid, and which is effective to prevent flow of noxious gases through the trap even upon evaporation of the water seal of the trap.
A further object resides in the provision of a structure of this character which is adapted for forming either the full three-quarter, and half 8 types of trap.
It is still further my object to provide a trap structure of this character which may be formed of a minimum number of simple and readily assembled parts.
With the above and other objects and advantages in view, which will be apparent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of parts which will be hereinafter more particularly described and defined by the appended claim.
In the accompanying drawings:
Figure 1 is a vertical sectional view through a surface drain type of trap embodying my invention.
Fig. 2 is a vertical sectional view through another trap structure.
Referring now more particularly to the trap shown in Fig. 1, there is provided a U-shaped tubular casting section 5 havingthe upper end of one of its legs enlarged in cup shape to provide a sediment basin 6, said basin having an upstanding annular flange 7 in its base which is disposed under a hemispherical shield member 8 secured by a bolt 9 to the central portion of a cover 10 seating in the mouth of the basin 6. The upper end of the other leg of the U-shaped section 5 is enlarged to form a valve cham- Patented Dec. 28, 1920.

ber 11 which is connected by an integral web portion 12 with the mouth portion'of the sediment basin 6 and which is closed by a plug 13 threaded in its upper portion.
A tubular section 14 extends from the outer side of the valve chamber 11, said extension being disposed at an angle of approximately forty-five degrees to the adjacent leg of the U-shaped section 5, and this extension is adapted for threaded or otherwise detachable engagement of a coupling member 15 which, by reason of its angular shape may be adjusted with respect to the tubular section to procure what is termed in the trade, either a full type of trap or a half 8 type of trap, and if desired a straight coupling section maybe employed to procure the three-quarter type, the various positions of the coupling member other than the half position being shown in dotted line.
An upstanding annular flange 16 is formed in the base of the valve chamber 11 on which is engaged a valve seating annulus 17 preferably formed of copper and being frustoconical in shape to fit the corresponding beveled top edge of the flange 16, the side edges of the annulus being bent to engage the peripheral faces of the flange whereby to firmly hold the annulus in place. A weighted ball valve 18, also preferably formed of copperis disposed in the valve chamber for seating engagement on the annulus 17 and this valve is prevented from moving to a position closing the outlet section 1% by a lug 19 secured to and depending from the closure plug 13 of the valve chamber.
An exceedingly simple and eficient trap structure has thus been provided which incorporates a valve mechanism therein whereby to prevent retrograde flow of liquid through the trap, the valve being also effective to prevent flow of gas in the event that the normal water seal of the U shaped section 5 should become evaporated. Upon removal of the valve 18, the trap structure is opemted in the conventional manner. Attention is particularly directed to the simplicity of parts and the ease with which said parts may be castand assembled.
Fig. 2 shows the application of my invention to a type of drain trap adapted for use in connection with tubs or other receptacles. In this structure, the U-shaped watersea-l section 20 is provided with a cleanout plug 21 in its bight and has the free end of one of its legs threaded at 22 to receive a dis charge pipe. The free end of the other leg of the trap is provided with an outstanding annular flange 23 on which is seated the lower end of a cylindrical valve chamber 24-, a suitable gasket member 25 being prefcrably interposed between the Wall of the valve chamber and the flange. These parts are held in assembled relation by a coupling ring 26 threaded 011 the lower end of the chamber Wall 24 and having an inwardly extending flange engaging the bottom face of the flange 23, this coupling ring being assembled by sliding it over the U-shaped section 20 from the opposite end of said section. A. tubular section 27, similar to the section 1% of the type of trap shown in Fig. 1 extends from the upper portion of the valve chamber 24, being adapted for connertion with a coupling member 28. weighted ball valve 29 is disposed within the valve chamber and is adapted to seat on an annulus 30 to arcuate in cross section and engaged in the mouth of the Ushaped section 20. A lug 31 is secured to the upper portion of the wall of the valve chamber 24 to prevent movement of the valve to a position closingthe outlet section 27. By reason of the angular outlet section 27, this trap structure is also adapted for various desired general shapes and its operation is similar to the operation of the structure de scribed in Fig. 1.
What is claimed is:
In a drain trap, an upstanding substantially cylindrical valve chamber having an inlet opening in the bottom, a tubular out let section extending laterally from and merging with an upper side portion of said chamber, a valve seat in the bottom portion of said chamber and surrounding the inlet a ball rheclr valve in the chamber and en gageable on said seat and an inward projection in the upper portion of the chamber above the lower portion of the meeting edge of the valve chamber and tubular section, said projection being inclined from the wall of the chamber toward the outlet to prevent foreign matter adhering thereto, and being engageable with ball valve upon upward movement of the ball in the chamber, to hold said ball between said projection and the meeting edge of the valve chamber and tubular section.
In testimony that I claim the fore oing l have hereunto set my hand at Eau Claire, in the county of Eau Claire, and State of \Visconsin.
