To all 'whom t may concern Be it known that we, JOIrN M. Trrozur-` SON and WILLIAM H. THoMrsoN, citizens of the United States, residing-at` Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Drainpipe Plugs, of which the following is a specification.
This invention relates to plugs or stoppers for drainpipesorlthe like, and more particularly to plugsor stoppers for drainpipes of the kind which are not provided with screw threads or other means to which 'a plug or stopper may be secured.
Most drainpipeswhich are now used for draining basements or cellars and which connect with sewers, are not provided with plugs7 and consequently, if the waterbacks in the sewer,
the cellar or basement may become flooded. `Sewer gases` and odors also sometimes enter the `cellar or basement throughfthe drainpipes. When it is desired to provide the drainpipewith a plug, 1t is generally necessaryfto remove the upper section of the drainpipe and replace it `by a corresponding seCtOIl 0f Pipe having a threaded upperend,which necessitates breaking through the cellar or basement floor and digging below the floor to remove the section tion.
The objects of this invention y are to provide a plug for drainpipes which can be readily applied to drainpipes of usual con-l does not necessitate any the plug in a. drainp-ipe, or the removal therefrom; also to improve the' construction of devices of this kind in the otherrespects hereinafter specified. yIn the accompanyingk drawings:

means used for expanding the gasket of the plug.
. Fig. '4c is a similar sectional elevation" showing the plug in operative position in a pipe. v
Fig.V 5. is a top plan view of the plug showing the wrenches in operative relation GOk ythereto for expanding the gasket.
A represents theusual drainpipewhieh may be arranged 1nv a cellar Vlicor and a 1s 65 `theusual perforated cover therefor.
The drainpipe plug embodying the in-` vention shown in the accompanying draw-y ings includes two gasket-compressing mem-` bers B andv C which are .adjustableA rela-` .70" tively toeacli` other, the upper member B vbein;` internally threaded as `shown at and the lo-wer member C having an upper shank portion c externally. threaded toen-k gage with threads 7). The upper member 75` .B preferably has an enlarged `flange 7J `which, prevents the upper part of the plug from entering into a drainpipe. and the `lower member isfpreferably providedwvith an outwardlyeXt-ending flange c engaging an levpansible gasket D, preferablyr made of rubber or other suitable material. i E represents a spacing member or washer whichis '1 varranger: between the expansible gasket D and the lower end of the upper gasket-compressing member B. When the upper and lower .members B and C arel turnedrelatively to each other the opposite `faces of the gasket will be pressedtoward each other, causing they gasket to expand as shown yin Figs. l and 4. The spacing member or washer E is preferably, though not necessarily used and servesto prevent the lower end of the member B from wearing or rubbing on the gasketl l),` and' also eliminates 95 the friction whichwould result from hav--` ing the lower end of the upper gasket-compressing member bear directly against the gasket. ,l H y The lower gasketfcompressing member C l 2)" of the upper member l?) i5 io` larities or roughness on thewalls oit-the `rthreadedfportionb ofthe member `B.
