1 Application May 22, 1933.

' 3 Claims. (01. 4 -286") Mypresen't invention relates to improvements in strainer t'raps for use in drain pipes or waste pipes of kitchen sinks,washstands, wash bowls, and similar fixtures, and-especially'designe'd for use in barber shops, beauty shop's, hair dressing parlors'or salons, and other tonsorial establishments where the waste or drain pipesare likely to receive hairs among the debris or refuse that may flow from the wash stand downthrough the waste- As is well known; in tonsorial parlors especially,

particles of solid refuse or' debris containing greases of various natures, and hairs, frequently foul and clog'up the waste pipe through which they are expected to flowfcausin'g annoyance, unsanitary conditions, and expense for plumbers bills on account ot'repairs. To overcome these objectionable features I have invented a removable strainer-trap, or trap device, which will readily permit the passage or flow of liquid'refuse through the waste pipe, but which is effective in trapping, collecting, or gathering all hairs and grease contained in the debris or refuseth tm ay be emptied into the'waste pipe. f The trap device may readily be, regular intervals," cleansed of' the accumulated hair and debris, and then replaced, asgr'equiredfi thereby eliminating unsanitary conditionsgand preventing clogging or stopping up of thewaste pipes. Q

The invention consists incertain novel combinations and arrangements of parts as will hereinafter be more fully set forth and claimed. In the accompanying drawing I have illustrated one complete example of the physical'ernbodiment of my invention anda slightemodification thereof, wherein the parts are combined'and arranged according to one mode I have thusfardevised for the practical application of-the principles of my invention.

Figure 1 is a sectional view showing a portion of a sink or washbowl with a drain pipe or wastepipe, and with my strainer-trapsuspended or supported in position for performing its functions.

Figure 2 is a sectional detail view showing the v V manner of rigidly securing the strainer to the view, as at line 3-3 of Figure 1 showing the bristles of the trap occupying substantially" the entire cross area of the pipe. r

Figure 4 is a detail sectional view at the upper moved at Serial o. 672,277

end of the trap showing am fied form of supportingor suspending means'for the trap. Figure 5 is a plan view showing .the relation of the cross-wires or suspending means ofzFigure 4, to the mouth of'the waste pipe. 1 I

In order thatthe utility and general. arrange ment of parts of the invention may readilybe understood I have shown in Figure 1 aconventional waste pipe or drain pipe 1, 'whichmayrhave a-supporting or suspending annular flange 2 that is seated as usual in'the drain opening of a vessel 3, which, as before stated, may be a kitchensink, wash stand, washbowl, or other similar=rfixture.

Whilethe strainer trap of my inventionmaybe adapted for'various uses in -collecting,'gathering,- or trapping debris or refuse to prevent 'its'pas sage through the waste pipe, the strainer-trap is especiallyeffective in trapping hairs 'and grease' that may flow with" water as off throughj'thepipe. In oneform'of my invention 'I provide" the trap device with a perforated strainer-plate 4', of con cave-convex shape, and of well known type, and the stem b of theitrap "is fashioned of-" twisted wires which pass throughacentral hole in the -strainer-plate. The-stem and plate 'are'rigidl'y 'secufred together in any suitable manner, as for instance by forminga head'or knob B'on the con vex-or -jup'per face of the plateyand welding-or soldering the T head, stem and plate together. Th'ejknob may be used as a handle when insert ing the trap in the waste pipe, or when withdrawingthe trap from the pipe, and the strainerplate', which forms a perforated cover for the opening or mouth of the Waste pipe, also performs the function of a support or suspending means for the trap when in position in the pipe.

Below the stem 5, the twisted wires are fashioned asla spiral core '7, the coils of which core may be of any suitable diameter, and of any appropriate length, but the spiral core coils around the axial center of the pipe and is spaced a suitable distance from the cylindrical walls of the p p r r 'In the twists of the coils of the spiral core is the water is passing secured a spiral ribbon 8, of bristle material simthe drawing the spiral core is located intermediate the outer and inner edges of thespiral ribbon', and the bristles extend outwardly from the core to frictionally engage the inner wall of the pipeyand they also extend inwardly from the 'ilar to the material employed in brushes, and these bristles may be of hair, wire, or other suitable materialfor'the purpose. As indicated in the trap and of the pipe.

The bristles are so disposed that they occupy the entire cross area of the pipe, in order that the water may not carry any hairs past the trap, .but

the water is free to flow, not only in a spiral column through the trap, but directly through the bristles of the trap. The core is spaced from the axial line of the trap in order not to form an obstruction against passage of water directly through the center of the pipe, and the water is free to flow through the bristles that extend outwardly from the spiral core. The stem 5 is of sufficient length to permit the formation of a head of water above the trap that will insure a flow of water straight through the trap at all points except for the core, and any resistance offered to the flow of water by the bristles is compensated for by the spiral passage through the trap that permits flow of water. Thus it is practically'impossible for a hair to pass through the trap without becoming entangled in the bristlesat' some point in the trap, and as the hairs are tangled and matted in the bristles they are twined and intertwined in suchlmanner that they cannot be dislodged by the flow of water through the trap. Solid particles of grease, refuse, and other debris are also lodged in the trap and tana ed in. the bristles.

At regular intervals the trap is removed from the waste pipe and the hairs and accumulated debris are removed therefrom, after which the trap is again inserted in place.

The bristles and the spiral core, preferably, pcssessresiliency, thus permitting the exterior periphery of the spiral ribbon to be made larger in diameter than the bore or inner diameter of the'pipe. Becauseof this resiliency, the trap may be inserted into the pipe in such manner as to scrape the inner face of the "pipe, and some of the bristlesmay be bent out of the conventional shape shown in Figures 1 and 3 of the drawing. As the trap is shoved downjin the pipe, some of the bristles that extend outwardly from the spiral core are caused to bend upwardly, and these upwardly bent bristles are instrumental in providing obstructions against which the hairs are likely to lodge and become entangled, When the trap is removed, the bent bristles, by theirfrictional contact with the wall of the pipeand spiral coil to, or across the center or axial line of due to their resiliency, are returned to normal position, radiating directly from the spiral core. The insertion, and removal of the trap from the -.pipe, with the bristles in contact with the wall of the pipe, maintain the surface of the pipe free from debris and insure a sanitary condition within the interior of the pipe.

In Figures 4 and 5 I have illustrated a modified form of support or suspending means for the trap Within the waste pipe. In these figures of the drawing, the two ends 9 and 10 of the twisted wires of the stem are straightened out, and they are of suificient length to extend across the mouth or opening of the waste pipe. These bent ends thus form a cross-head which supports the trap and prevents excessive flow of water from packing the trap in the pipe, and at the same time the cross head is used as a handle when inserting and removing the trap.

While I have shown one exemplifying type oi the trap, it will be understood that changes and alterations are contemplated, and may be made in the illustratedstructures, within the scope of my claims, andwithout departing from the principles of my invention. h h
