ANCHORING STOPPER Filed July 30, 1938 INVENTOR LINUS A.-CARROLL Patented Jan. 9, 1940 UNITED STATES PATENT OFFlCE Claims.

My invention relates to stoppers for wash bowls, bath tubs, laundry trays and such like.

My object to provide a stopper having means and facilities whereby the stopper can be anchored While in use so as to prevent accidental dislodgement. Other objects will appear as the description progresses.

The single figure represents a wash bowl partly broken away showing my stopper disposed in the outlet, the stopper being partly in section.

Although I show the preferred embodiment of my invention, I do not thereby limit myself to the precise form showmbut wish it understood that within the scope of what hereinafter is shown, various changes in the details of construction may be made without departing from the spirit of the invention.

My device comp-rises a stopper body, an anchoring means, and an operating means for the anchoring means. I The stopper body shown in the drawing has a head portion I and a neck portionZ, and is normally disposed in the outlet 3 of a wash bowl or other receptacle as shown, 'Thebody is preferably made of yieldable material such as rubber but may be of hard material for some uses. The head may be of hard material and the neck of a soft yieldable substance if desired. The head may be of various shapes but I have illustrated an oval head which is convenient to grasp and which permits wet fabric to be slid over it without danger of catching the fabric.

A'tubular guide 5, provided with a pair of depending projections 66, is disposed in the body of the stopper and retained therein by an annular fin I. An operating pin 8, provided with a head 9, is slidably disposed in the guide 5 and extends therethrough. A pair of anchoring arms Ill-l0, provided with friction. shoes lI--Il secured to their free ends by cement'or otherwise, is pivotally connectedto the pin 8. pivotally connects each anchoring arm H] to a projection 6 on the guide 5.

Assuming that the stopper is in position as shown in the drawing, it is evident that as long as the pin 8 is not pushed downward the shoes l I resist all effort to dislodge the neck 2 because any efi'ort to lift the stopper causes the arms II] to press more firmly against the outlet wall. If however, the pin 8 is pressed downward, the arms l0 swing on the links [2 causing the shoes II to recede from the wall of the outlet and thereby facilitate removal.

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

1. Astopper with means to prevent accidental withdrawal from the drain outlets of wash bowls and the like comprising, an oval head and a A link 12.

cylindrical neck; an operating pin extending through said head and neck; a plurality df.

anchoring arms pivotally connected to one end of said operating'pin; a link pivotally connected to each anchoring arm between the free end and the point of connection to said operating pin, said anchoring arms being pivotally connected to the central portion of the bottom of said neck; and

a friction shoe on the free end of each anchoring arm.

2. A stopper for wash bowls and the like, said stopper including an oval head and a cylindrical neck; a guide mounted in saidhead and neck and extending through. said neck; lugs. on the ex posed end portion of said guide; an operating pin' extending through said guide; a plurality of anchoring arms pivotally connected to one end of said operating pin; and a link having one end connected to each anchoring arm between the free end and the point of connection to said operating pin and the other end connected to one of the lugs on said guide.

3. An anchoring stopper in combination with the outlet of a wash bowl and the like, said stopper comprising a head and a neck, said neck being disposed in said outlet; an operating pin extend ing through said head and neck; a plurality of anchoring arms pivotally connected to the lower end of said operating pinand extending to the interior wall of said outlet; and a link connected to each anchoring arm between the point of con nectionto said operating pin and the opposite end of said anchoring arm, each link being connected to the bottom of said neck.

4. The combination of a rubber stopper having a head and a neck; a guide extending through said head and neck and provided with logs on the exposed end portion; an operating pin extending through said guide; anchoring arms piv-.

otally connected to one end of said operating pin; and a link pivotally connected to each lug and extending obliquely therefrom and connected to.

a point on an anchoring arm between the point of connection to said operating pin and the free end of said anchoring arm.

5. The combination with a wash bowl having an outlet in its bottom, of a stopper disposed in saidoutlet; an. operating pin extending through said stopper beyond the bottom thereof; a pair of links attached to the bottom of saidstopper and extending obliquely downward away from the center of said stopper; and a pair of anchoring arms connected to the lower end of said" operating pin and extending therefrom to the interior side of said outlet, each link being con-- nected to an anchoring arm between the two ends of said anchoring arm.
