Specification of Letters Patent. Patented A111. 19119 Application filed August 3, 1918. Serial'No. 248,194. i

disposed transversely of the drain for com municating therewith.

provide on the plug of the clean-out pipe a member having a limited guided movement relatively to the clean-out pipe, whereby to limit the opening movement of the plug and thereby, in preventing its complete Withdrawal, avoiding the misplacing or loss of the plug.

A further object of the invention is to dispose the plug when open in a position to prevent the closing of the cover until the plug is restored to the clean-out pipe, whereby the latter will not be thus accidentally left open for the escape of sewer gas.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a longitudinal. vertical section of a drain and trap equippedwith my invention, showing the c1ean-0ut plug open affording access to the clean-out pipe and at the same time obstructing the closing of the drain cover;

Fig. 2 is a simil. r view with the plug in position closing the clean-out pipe and with the drain cover in the closed position Fig. 3 is a partly sectional plan view.

The drain designated generally by the numeral 10 may be of any approved form having a trap 11 leading to the soil pipe 12, the drain having a clean-out pipe 13 above the trap for affording access to the pipe 12, said parts being generally known. The numeral 14 indicates the perforated cover of the drain and will be hereinafter particularly referred to.

The clean-out plug 15 is adapted to be screwed into the end of the clean-out pipe 13 at the flaring mouth of the drain beneath the cover. In order to prevent the complete withdrawalof the plug the latter isequipped with a retainer 16, here shown as'U-shaped or of yoke form, the cross bar of which is SWlVGlGCl to the plug 15"by a bolt 17 extending axially through said pl'ugQThus, the

plug may turn relatively to theretainer 16 in inserting and removing the plug. Said retainer has side arms 18 passing through fixed keepers 19 on" theclean oiit pipe 13 at the interior, whereby as the plug is inserted or removed the arms 18 will have guided sllchng movement in said keepers. The arrangement of the arms 18 and keepers 19 is v such that when the free ends of the arms are An important object of the invention 15 to brought adjacent to the keepers the arms 'will engage the keepers to prevent complete withdrawal of the plug 15 from the drain, the arrangement in the given example consisting of a notch 20 in each arm 18 whereby the arms will drop into engagement with the keepers. Thus, if it should be attempted to removethe plug through the top of the drain after removing the cover 1 1, then the removal must be done deliberately because the tendency of the arms 18 will be to engage their notched portions 20 with the keepers 19. The plug 15, however, with the arms 18 still engaging the keepers may be permitted to lie in the flaring portion of the drain as shown in Fig. 1, leaving ample clearance for the insertion of a clean-out wire or other tool in the pipe 13. Thus, the accidental loss or displacement of the plug will be prevented.

I utilize the retainer plug to prevent the closing of the cover 14 by obstructing the closing movement thereof, for which purpose in the illustrated example a depending lug 21 is formed on or secured to the cover at the under side in a position to rest on the arms 18 or one ofthem, when the plug is in the open position as shown in Fig. 1. The cover at the opposite end from the lug 21 has a lateral lug 22 engaging a mating notch 23 in the drain. Thus, the arrangement is such that the opening movement of the plug will carry the arms 18 in a path across the drain and beneath the cover to form an obstruction to the latter.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without departure from the spirit of the invention as defined in the appended eiaiins.

Having thus describedmy invention,

claim as new, and desire to secure by Letters Patent:

1. A drain including a clean-out pipe extending laterally from the drain, a cover for said drain, a plug for said pipe, and a member on said plug and movable therewith, in the-opening of the plug, in a transverse path below the cover to a position to ,obstrnctthe closing of said cover until the plug is re- ,Pleeed i the ,Qleemeeb Pi e- 2 (train infil lditlg a lateral elean-out m ne e the 0 said n ne, mean t l i th m eiee i th nineteen t me said pipe t thee po it e the nlee in t a sev freimsais rfimiei aed oac in m n 1 the cover and plug to cause the plug to ob struct the closing of the cover until the plug is in position in the clean-out pipe.
