R. H. VANERSTROM S INK DRAIN TRAP Filed Aug. 17, 1957 INVENTOR WITNESS Patented Dec. '13, i938 UNITED STATES PATENT O'FFl CE 5 Claims.
This invention relates to sink drain traps and has for the primary object the provision of a device of this character which will be extremely simple to install on a sink or any other 5 device employing a drain and may be manufactured and sold at a low cost.
Another object of this invention is the provision of a device of the above stated character which will efficiently trap foreign matter which 10 would have a tendency to clog a drain pipe and which may be easily and quickly emptied of such foreign matter and also may be readily ad- J'usted to close the trap to the drain pipe when desiring to retain water in the sink and further 18 has means for connection to hot and cold water supply pipes whereby water may be admitted to the sink by way of said device and further to permit cleaningof the drain pipe by water under pressure from one of the supply pipes.
, go With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which- Figure 1 is a top plan view illustrating a reservoir of the trap with the sediment bowl removed.
Figure 2 is a top plan view illustrating the bowl.
Figure 3 is a side elevation, partly in section,
illustrating the reservoir.
' Figure 4 is a vertical sectional view illustrating the sediment bowl mounted in the reservoir and positioned to close the latter to the drain outlet or neck.
Referring in detail to the drawing, the numeral l indicates a substantially cup-shaped reservoir including a rounded portion 2 terminating in an outlet or discharge neck 3, externally screw threaded, as shown at 4, to permit the reservoir to be readily connected to a drain pipe (not shown). The rounded portion 2 at the inner walls thereof is tapered to form a seat 5. The upper end of the reservoir is of an increased thickness and internally screw threaded to receive a screw threaded retaining ring 6 of the flange type. as shown at I. The retaining ring is employed for detachably securing the reservoir onto a sink (not shown) or, if desired, the reservoir may be detachably secured to the sink by stud bolts threaded into screw threaded sockets 8 formed on the thickened portion of the reservoir.
Substantially wedge-shaped lugs 9 are formed in the bowl adjacent its upper end and each tapers from one end to its opposite end.
A bowl ID has a closed end and an open end. The closed end of the bowl is reduced. in shape to form a valve to engagewith the seat 5 when desiring to close the reservoir-to the drain pipe (not shown) connected to the outlet neck 3. The closed end of the bowl is rounded, as shown at II, which when spaced away from the seat will aid in preventing air in the drain pipe (not shown) from forming a bubble which tends to create back pressure and destroy the siphon effect of the drain pipe. A portion of the bowl has a series of staggered slots l3 spaced a selected distance from the closed end of the bowl to permit liquid to escape from the bowl into the reservoir with the foreign matter of the liquid settling in the lower end of the bowl and thereby become trapped in the bowl. Spaced tapered lugs I5 are formed on the open end of the bowl and contact the walls of the reservoirto space the bowl therefrom. Also formed on the bowl are iinger pieces IE to facilitate a person removing and replacing the bowl in the reservoir. The finger pieces are of loop formation and are arranged horizontally within the bowl below the lugs l5. The lugs l5 may move freely between the lugs 9 and the reservoir when desiring to remove the bowl from the reservoir or to place the bowl within the reservoir. The lugs I5 may be positioned on the lugs 9 for the purpose of supporting the bowl in the reservoir with the valve portion thereof disengaged from the seat 5 which will permit liquid to flow from the reservoir to the drain pipe. Whenever it is desired to close the drain pipe to the reservoir the bowl is lowered in the reservoir by bringing the lugs 15 past the lugs 9 and under the latter. The bowl when rotated relative to the reservoir with the lugs l5 under the lugs 9, said lugs have a camming action tightly forcing the valve portion against the seat 5.
Pipe nipples I! are formed on the reservoir and extend into the latter in the form of nozzles Ill. The pipe nipples I! are adapted to be connected to hot and cold water pipes. Of course control valves are provided in said pipes. A nipple I9 is formed on the reservoir and communicates with the latter below the seat 5 and is adapted to be'connected to one of the water supply pipes so that whenever it is desired to flush or clean out the drain pipe water under pressure may be admitted directly into the neck 3. At this time it is preferable that the bowl be lowered to close the reservoir to the neck 3. The
bowl when in the last-named position will permit hot or cold water to be admitted to the sink by way of the reservoir without said water passing to the discharge neck 3.
What is claimed is:
1. A sink trap comprising a reservoir including a discharge neck adapted for connection to a drain pipe, means for detachably securing the reservoir onto a sink, a seat formed in said reservoir, a sediment bowl xemovably mounted in said reservoir and adapted to be adjusted against said seat for closing the reservoir to said dis- 7 a discharge neck adapted for connection to a drain pipe, means for detachably securing the reservoir onto a sink, a seat formed in said reservoir, a sediment bowl located in the reservoir and including a reduced rounded closed end shaped to form a valve element and a sediment trap, means for releasably and adjustably mounting the bowl in the reservoir whereby said bowl may be removed and replaced in the reservoir and adjusted relative thereto to engage and disengage with the seat. 7
3. A sink trap comprising a reservoir including a discharge neck adapted for connection to a drain pipe, means for detachably securing the reservoir onto a sink, a seat formed in said reservoir, a sediment bowl located in the reservoir and including a reduced rounded closed end shaped to form a valve element'and a. sediment trap, finger loops formed on said bowl, spaced tapered lugs formed on the reservoir, spaced tapered lugs formed on the bowl and adapted to cooperate with the first-named lugs in supporting the bowl in either elevated or lowered position and when in a lowered position to engage with the seat and to permit removal and replacement of the bowl in the reservoir.
4. A sink trap comprising a reservoir including tapered lugs formed on the reservoir, spmed tapered lugs iormed on the bowl and adapted to cooperate with the first-named lugs in supporting the bowl in either elevated or lowered position and when in a lowered position to engage with the seat and to permit removal and replacement of the bowl in the reservoir, pipe nipples formedon and communicating with the reservoir adapted to be connected to hot and cold water pipes, a pipe nipple formed on the reservoir and communicating with the discharge neck below the seat and adapted to be connected to a water pp y pip 5. A sink trap comprising a reservoir including a discharge neck adapted for connection to a drain pipe, means for detachably securing the reservoir onto a sink, a seat formed in said reservoir, a sediment bowl located in the reservoir and including a reduced rounded closed end shaped to form a valve element and a sediment trap, finger loops formed on said bowl, spaced tapered lugs formed on the reservoir, spaced tapered lugs formed on the bowl and adapted to cooperate with the first named lugs in supporting the bowl in either elevated or lowered position and when in a lowered position to engage with the seat and to permit removal and replacement of the bowl in the reservoir, pipe nipples formed on and communicating with the reservoir adapted to be connected to hot and cold water pipes, a pipe nipple formed on the reservoir and communicating with the discharge neck below the seat and adapted to be connected to a water supply pipe, said bowl having an external flange to abut walls of the reservoir for spacing the walls of said bowl from the reservoir, said bowl having a plurality of staggeredly arranged slots.
