GREASE TRAP APPLICATION FILED MAR. 9, 19m.

NITED STATES PATENT OFFICE.
WILLIAM S. MILLS, OF FLORENCE, SOUTH CAROLINA.
GREASE-TRAP.
To all whom it may concern Be it known that WILLIAM S. MILLS, a citizen of the United States, residing at Florence, in the county of Florence and State of South Carolina, has inventedcertain new Q and useful Improvements in Grease-Traps, of which the following is a specification, reference being had to the accompanying "drawings,
This invention relates to traps, and par- Igticularly to traps for catching and separating grease from water or other liquids drain- ;ing from a sink.
from the sink.
A further object is to provide a construction of this kind including an outer body or casing which is intended to be permanently connected to the waste pipe of the sink and the waste pipe leading the sewer or other point of discharge, and to provide an interior strainer removable from the outer body'or casing.
" Still another object is to provide a strainer as referred to with means whereby it may be readily taken apart for cleaning, and furstrainer may be held in proper position withther "provide means whereby the interior in the outer casing or body so that the waste from thecasing or body.
. 1 strainer,
pipe may discharge thereinto.
Still another object is to so construct the grease trap that the strainer may be readily "removed, leaving the outer body or casing open for cleaning and to permit the strainer to be cleansed. jStill another object is to provide an auxil- 40 iary strainer disposed at the junction of the outer body. or casing with the waste pipe leading tothe sewer so as to catch any grease whichmay by any chance escape the main body of the trap, and provide means whereby this auxiliary strainer may be removed Other objects will appear in the source of description.
panying drawings, wherein t Figure 1 is a longitudinal sectional view ofv my improved grease trap;
Fig. 2 is a perspective view of the upper portion of the strainer; and j Fig. 3 is a vertical'section of the auxiliary Specification of Letters Patent.
Apulication'flled March 9, 1918. Serial No. 221,539.
Referring to these drawings, 10 designates the body of the trap, which is made of sheet metal or other suitable material, this body, for the greater portion of its length, being uniformly tapered from one end to the other, the smaller end of the body being closed by a wall 11 and having leading therefrom a tubular connection 12 which may lead to the sewer or other point of discharge. The opposite end of the hollow tapering body or casing is downwardly flanged as at 13 and then continued to provide an annular wall 14, which is screw-threaded for engagement by the screw-threaded flange of a cover 15. A waste pipe 16 leading from the sink enters the casing 10 adjacent the flange 13 at one point.
Removably disposed within the casin 10 is a grease strainer or catcher, whic 1 is formed in two parts. One of these sections or parts comprises a tapering annular member 17 of imperforate metal, having an elongated opening 18 at one point therein. The other section 19 is formed of wire gauze or like material and constitutes practically a tapering pocket closed at its lower end and provided with a handle 20. The gauze section 19 is connected to the section 17 by a screw-threaded union or joint 21 formed in any suitable manner as by providing a metallie band at the large end of the section 19 having screw-threads which will engage screw-threads in the section 17.
At'its upper end the section 17 isformed with a flange 22, which is provided with notches 23 engageable with lugs 21 projecting upward from the flange 13. These notches'and lugs are so arranged that when the lugs are engaged in the notches 23 the opening 18 will be disposed immediately beneath the waste pipe 16, thus preventing such positioning of the strainer within the casing 10 that the waste pipe 16 will be out of line with the opening 18. A cover 25 detachably engages the large end of the member 17, the cover being provided with a suitable handle.
The small end of the casing 10, as before stated, engages with the waste pipe 12 and at the junction of the waste pipe with the casing 10 or body I provide an auxiliary strainer 26 which is approximately hemispherical in form and formed of wire gauze, this strainer being mounted upon a rod 27 carrying at its upper end a plug 28 which has screw-threaded engagement with the wall of the casing 10 and which is provided with a handle (Elle strai e -may be. h ld upon the rod 27 by reducing the extremity of the rod and screw-threading it forthe" 116- the two partsof the straiiie'r'a re removable fromeachoth'err I v, 1
' By the use'or'in inventionfprovision is made for trapping or catchingthe'gi'ease whichmay pass through the ,Waste'fpipeQsO that the grease will not clog the pipes leading to the sewer, which is very lia hle' to happenfand furthermorethis does away with the necessity of 'ClGaIllIig' these waste pipes iw ienltliy become clogged, which 'isia' very disagreeable job. Again by reason fof the fact that the body 10 is inelin' ed downward and toward the "waste pipe 12, fall liquids passing intofthe' trap: will flow gravity into the wa'stefpipe' and will not 'collect in the trap. Where water. or. other liquids collectf'wit'hin the trap, the liquid is very liable I to freeze thus bursting the. trap T or preventingthe free flow of the same. Inasmuch as the opening l ris relatively *large, in relation to the waste pip 1:6,'it Will be obvious tharuierewiu belno chance for water topass' dciv rfn ex teriorly ofthe strainer. 1
