@ UMZZ Joniv H. ownns, or BACINE,,WISGO1\TIN.

To allwhom itimag concern: 1 Be it known that'l, JOHN H. ()wnNs, a cltlzen of the :United States, andresident of Racine, in the county of Racine and'State of \Visconsin, have invented certain new and useful Improvements in-Traps or Clean-Out Covers; and I do hereby declare that the following is-a full, clear, and exact description .thereof. e

My invention refers to cap closures for plumbers traps or clean-out covers, which are particularly adapted to be sunk into the floors of bathrooms or the like, the caps being in threaded union with the mouth of the trap whereby they can be removed for various purposes.

In caps for traps of this general type the usual method of removing them is to provide such traps with project-ions, and these projections are a constant annoyance as they preclude the desirability of obtaining a'flush floor and thus frequently cause individuals to stumble over the projections.

Other types of caps attempt to overcome this objectionable feature by using countersunk recesses. These recesses are formed so as to avoid projections above the floor,'but

in this type of cap there is a liability of individuals catching the heel of their shoe or other part of the foot into the recess, and furthermore such recesses form dirt traps. Hence they do not overcome all of the objectionable features of the projecting head, nor do they meet the demand for the flush drop coveror cap. V

My invention has for its object to provide and efiective flush cap time provision is had for removing such flush cap closure. The arrangement and construction of my inventlon, essentially embod es a polygonal recess in the upper face of the cap,

and a complementary shaped plate. adapted to fitwithin the recess to present a smooth uninterrupted surface. Under normal conditions the plate is also provided upon its under surface with a projecting head for the reception ofa suitable tool. Thus when it is desired to remove the cap,,the plate is 11fted from the recess and reinserted therein, with its head side projecting upwardly so as to provide means for receiving the tool, whereby the cover can be readily unscrewed from the body of the trap. I

With the above objects in view, the invention consists in certain peculiarities of con- T t-Ar on cnnaugou'r covert.

struction, combination andarrangement of parts as. are hereinafter set forth with ref-1 erence .to .the'accompanylng drawlng and subsequent claim.

-. Int-he drawing:

'Figure 1 represents a plan-view of'a cap embodying the features of my invention,- the 0 same being illustrated with-a square plate features.

Figure 2 represents across-section of the cap fitted tothe mouth of a trap of any desired type, the complementary,shapedplate for the cover being shown in its normal position with the head thereof extending downwardly, whereby a flush upper surface is" formed, thesection being indicated by line 22}of Figure 1, and

Figure 3 is a similar sectional view of thedevice, showing the removable plate reversed and fitted into the squared recess preparatory to the cap being removed. In this position, the cap closureis to all intent and purpose, taken in connection with the re- 1 movable plate similar to the standard cap in appearance.

Referring represents a cap closure having an annular threaded flange 2,-which flange is adapted to by character to the drawings 1 l enter the threaded mouth of a trap body 3,

as best shown in Figure 2.

The central portion. of the upper surface of the cap,fis provided with a recess l, the

same being formed with rectangular side walls 5, and the central port-ion of this re-. cess is countersunk to form a pocket 6. The

pocket, in this instance, is shown with recsaid pocket is adapted to fit snugly against the sideedges of there cessfi to thus form an uninterrupted surface, when'the upper face 9 of the plate is exposed. Hence it will be seen that the plug plate is provided with a smoothface, and from its opposite face there is extended a squared i I.

'7, which'is provided for the purpose 1 Y head of receiving a tool,.whereby the cap closure can be removed when desired.

As shown in Figure 3 of the drawing,the plate 8'has been reversed with relation plug:L to t e cap'rec'ess- 4, whereby the head 7 extends above the floor for the purpose of receiving the tool, and in Figure 2 of the draw ing, the plate is shown in its normal condition, in Which it forms in connection with the adjacent surface of the cap, an uninterrupted face, whereby the recess in said cap is closed and there is no liability of an accident, due, to an individual coming in contact With the projection. As shown in Figure l in this instance I have provided a slight indenture 5 in one of the Walls 5 of the rec tangular shaped recess, for the purpose of inserting a blade or other instrument, whereby the loosely fitted plug plate can be readily lifted out of its seat.

While I have shoWn and described the cap recess as being square and in nested-engagement with a correspondingly squared plate, obviously the shape of the recess may be varied Without departing from the spirit of the invention, as for example it may be six or eight sided. It is also intended that the screw threaded cap closure may be used in connection With any type of floor traps.

I claim:

Acap closure of the type described, having a polygonal shaped central recess in its face, thesarne being formed with a head receiving pocket and a complementary plug plate adapted to be loosely fitted Within the central recess, the plate having one uninterrupted smooth side and a tool receiving head extending from its opposite side, the head being adapted to. rest Within the recess pocket When thesmoothside of the plate is uppermost to thus form an uninterrupted cap surface.

in testimony that I claim the foregoing l have hereunto set my hand atrRacine,1in 'tl1e county of Raclne and State of Wisconsin.

JoHN H. OWENS.
