My invention relates to improvements in strainerstor -waste outlets, .and fhaS for its object to provide a simple, eheapand efficient strainer and means toi' retainingitin connection with an outlet., whereby the retaining means may be .detachablyapplied within an outlet fitting or pipe, Vthe* retaining meansperforated strainer adapted to fit over a sewer outlet, such as the outlet ofasink,

basin or other fluid containeror arlraiii,` anda retalner for the strainer comprisingl a block having bores a t.opposite-end sl respectively provided with right andflefthand r screw threads, and mem,bersctittingv said vbores andprovided with I u I A left hand threads. When the threadedmembers are retained from rotation within the outlet and the blockk is rotated inanappropriate direction said members will be caused to travel outwardly Afrom. ,the bloekinto engagement with the adjacent Walls of the .outlet, securing the bleek suspended in vposition therein, said bloolrloeing provided vvith a transversely threaded aperture to receive a screw adapted to pass through the strainer, f wherebyv the .latter is secured. inl position over the outlet,

My invention' comprises novel `details of improvement.that kwill be more fully hereinafter set :forth and Lthen-[pointed .out inthe claims.

Reference is to be had tothe aceoinpanying drawings froming a part-hereof, Whereinr-:- Fig. 1 is a partlyl broken side elevation illustrating my improvement in use; 0 Fig. 2 is an enlarged detail vertical section substantially on

line

2, 2 in Fig. 1; Fig. 3 is a plan view ot' the strainer; Fig. t is a detached perspective view illustrating parts for retaining the strainer; 5 F ig. 5 is a perspective viewv illustrating the position of parts when the retainer isfbeing applied in an outlet, and

Fig. 6 is a perspective view illustrating a tool for holding the threaded members from rotation when the retainer is being applied to or removed from an outlet.

Similar numerals ot reference indicate corresponding parts in the several Views.

The numeral l indicates a perforated strainer which may be dome-like, as illuscorrespondingright and trated,`or of vanyother,suitable or. well known forineadaptedftont over an outlet itting or pipeZleading tol a sewer, the loutlet being Votany well known form. lhave shown the strainer l in .an elongated form vto extend upwardly @from .thebottom of the container l a substantiai` distance andthe lower edge of thestrainer.provided with openingsA at l, whereby Yi-debris collects aroundthe strainer Water or other fluid vwill-be able to ow or percolate through` the apertures in f the strainerifor discharge, The outlet -litting 2 I haveillustrated is of a-well lmowntubular construction-adapted Vto be connected vto a Sewer-pipe3 and v.applied vto the bottom `of anysnitablecontainer ortluid, such as a sink, basin, tank, drain-or the .llikef Thetittinge@ is illustrated at the-bottom of a urinal t. At 5 is aybloclr, preferablyzof brass-ot length less than; .the transverse .diameter lof the-.outletamilx provided at each end-With a .bore' kivljlieh is internally threaded with lright and' left hand screw threads 7, Srespeetizvely 1at opposite ends adapted tofreceive members 9 and 10 whichA are respeotively provided with right and left hand threads in mesh withltheright and leftk hand threads of bleek-5.- The-members -9 and 10 arepreterably providedat theirouterends with reduced or tapering portions at 9, 10a to firmly impinge against-the opposing walls of the outlet fitting or pipe, The block 5 is shown polygonal 'inshapefsoas to recelif'e a t-ool, such as a-wreneh, for yrotating theblock. Said bloelr is alsof provided with atransverse threaded bore 5?"v to rece-ive the threads-eta serew.v 11, which screw is7 adapted to pass througha` hole 1a in strainer- 1Y with the header thesorew fitting-against the walls of the hole, as illustrated in Fig. 2.

I provide means to retain the members 9 and 10 from rotation when the retainer is being fitted within the outlet. I have shown the members 9 and 10 provided with holes l2, near their outer ends, adapted to receive the prongs 13 on a resilient tool or holder 14, which ma)7 be made of wire bent as illustrated in Fig. 6 to providetwo parallel arms 14 extending from the bent portion 14a, having two lateral portions 14h carrying the prongs 13, the prongs 13 being bent at the free ends of the arms in a direction substantially transverse tothe plane of the arms, so that when the prongs 13 are located in the holes 12 of the members 9 and l0 the retainer will be supported by aaid holder ll. The arms of the tool will move laterally when the attached memberst)` lll move relatively to block 5.

When the device is to he applied lo au outlet the members i) and ill are screwed into the block 5 sulliriently l'ar lo perniil said members to enter the outlet and said members are mounted upon the holder ll, the prongs of the latter entering the holes of said members,`whereupon the latter may be placed transversely within the outlet to the desired depth and can he retained hy hand in desired positiom and the tool or Wrench Will he usyl to rotate the block 5 and the holder 1l will retain the members El and l() from rotation. The rotation of block o with respect to they retained memu hers l) and 10 will cause the latter to travel outwardly respectingr the block and toward the opposing walls ot' the outlet into engagement With the latter, and suliicient pressure ol: the members against the Walls of the outlet .may be eileeted to cause the block to he retained by the expansion or elongation et the retainer, so that the latter will be snspended Within the outlet. The block 5 will be left in a position with its threaded bere or hole 5 extendingr in the direction ot the axis of the outlet and this may he acconr plished, if necessary, by individually rotating;r the members 9 and l()R slightly, h v means of the holder lel while the final position ot the block heilig elleeted. Alfter the re.` tainer has been secured within the outlet the strainer l will be planted over the outlet and the screw '1l will he passed through the hole il of the strainer and screwed into the hole 5 of the retainer to seenre the `strainer over the outlet, as illustrated in Fig. 2. By means ol the right and left hand connection `of members 9 and i() with the retainer bloei:

5 the hole 5 in said block will always he brought to a substantially central or axial position respecting;r the outlet when the re tainer is beingr fitted Within the latter', so that the hole 5 of bleek 5 Will be in a position to receive the screw 1l extending,r from the strainer irrespective of the extent el projmftiou ol the member.l l) and Al0 out wardly from block $3.

The arrangement described permits the application ot a retainer with its adjustable members withinfoutlets of dill'erent trans verse dimensions, Within limits ol the retainer, `and permits the ready removal oi the retainer from an outlet when desired hy merely holding the members Si and lll Vfrom rotation and unscrewing the block respectin el the latter.

l\ly invention is simple and cheap to manufacture can he readily applied to and rcmoved from an outlet, and permits the rtrainer readily lo he appliedand removed while the rotaimr remains secured within the outlet and without disturbing the re tainer in any manner,

Changes may be made in (he, details oli mmstruction set forth, within the -scope olf the appended claims` without departing from the spirit ot my invention.

I-lavdnf;r now described my invention what l claim is:-

LA device of the character described comprising a perforated strainer to tit over an outlet, a retainer lo be .fitted Within the outlet comprisingl a block provided with members at opposite ends to engage opposite sides of the outlet7 said bloei; and members having' cooperative threads lier causing outward and inward movement ol the members relatively to the block, the block being;` provided with a threaded transverse here, and a screw to engage the strainer and the threaded bore in the block to retain the strainer over the outlet.

2. A device as set forth in claim l`v in which the cooperative threads between the block and members are respectively right and lelt hand at opposite ends oi" the block.

l. A device as set Aforth in claim l, in

` which the members are each provided with a hole to receive a tool torel'ain the members from rotation when the block is being' rotated to cause operation of the members relatively to the block.
