COMBINED LAVATORY-BASIN PLUG AND OVERFLOW.

SPECIFICATION forming part of Letters Patent No.7527,802, dated October 23, 1894.

Application tiled December 22, 1893. Serial No. 494,400. (No model.)

will enable others skilled in the art to which.

it appertains to make and use the same. p

This invention relates to an improvement in combined overflow tubes and plugs for lavatory basins and it consists in the construction and arrangement of parts hereinafter described and definitely pointed out in the claims.

The aim and purpose of this invention is -the provision of improved means for plugging and sealing the discharge opening of a basin, which will also constitute an overiow for the same, and further in the provision of improved means for retaining the combined overflow and plug in its vertical adjustment and to also allow of an easy removal of the same. These objects are attained by the construction illustrated in the accompanying drawings wherein like letters of reference indicate corresponding parts in the several views, and in which` Figure 1, is a sectional elevation of the improvement and a portion of a basin, and Fig. 2 is a detail top plan View of the discharge opening.

In the drawings A represents the basin, B the drain pipe and C the discharge opening. In this opening is formed a spider D, having athreaded nipple cl on which is mounted a vtubular upright or stem E, extending up to a point above the high water line of the basin. This upright is cylindrical and of uniform size through its entire length.

F represents the plug, consisting of a hollow cylinder or shell of a diameter greater than the diameter of the upright, so that an intervening space is formed. This cylinder is of a length less than the length of the upright, and has its ends open. The lower edge of the cylinder F is formed with a suit able rubber .gasket f, which closely tits the edges of the discharge opening of the basin.

The cylinder F is slidingly held on the upright by having radial arms f formed on its inner face radiating from and fixed to collars, F', F2 fitting around the upright, and allowed a sliding movement thereon. The collar F2 is extended up above the cylinder F and has rigidly secured on its upper e'nd a ball or handle G capped over the upper end of the upright. On the upper edge of the collar F2 within the ball is formed an integral spring H having a curved end h constituting a catch, normally engaging the outer face of the upright, to hold the plug or cylinder Fin position by frictional contact.

An outer cylinder or trap bell, I, is secured to the sleeve F2 abovethe top of the inner cylinder, and extends down to a point slightly above the lower edge of the inner cylinder. The diameter of this bell is greater than the'diameter of the plug or inner cylinder, so that the water may pass up between.

In operationwhen the vbasin is filled with water, to a point above the plug-cylinder the water will flow out through the cylinders. When, it is desired to empty the bowl or basin, the ball is grasped and raised until the spring catch engages over the edge of the upright, which holds the cylinders in a raised position opening the discharge opening. The pressure of the spring on the upvright will also hold the cylinder up at anyl point before reaching theend of the upright. By this means it is only necessary to raise the cylinders, and the .trouble heretofore experienced in raising a cylinder and then turning the same to a proper point to lock y it in position is Wholly avoided.

It will be observed that by simply lifting the cylinders up the same may be quickly and easily removed from the upright, for cleaning purposes and by employing the bell, a trap is formed when a small amount of water is placed in the basin.

It is evident that many minor changes in the construction and arrangement of the parts of the' device can be made and substi--v tuted for those herein shown and described without in the least departing from the nature and principle of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters 5 Patent, is-

1. In alavatory basin, the combination with an upright secured. at the discharge thereof,`

an open end plugging cylinder, around the upright, arms, on the cylinder, collars on the inner ends of the arms fitted around the upright, an extension on the upper collar, a bell on the extension and a spring on the extension engaging the upright, substantially as described.

2. In a lavatory basin, the combination with an upright secured at the discharge thereof formed of uniform dimensions throughout; its length, of a plugging-cylinder surrounding the upright, supporting arms on the inner face of the cylinder, collars on the inner ends of the arms, surrounding the upright and a curved spring on the upper collar engaging the upright, substantially as described.

In testimony whereofI affix my signature in presence of two witnesses.

CHARLES H. MUCKENHIRN.
