AUTOMATIC OVERFLOW CONTROL Filed June 23, 1931 I/V VZ/V TOR 755mm 0. Jam 50m Patented Sept. 13, 1932 .FQEDERIGKO. aoH soN, 0]? LONG BEACH, cnnrronnrn I AUTOMATIC OVERFLOW CONTROL.

Application filed June 23,

This invention relates to an automatic overflow control whereby a tub of water is prevented fromrunning over if the faucet is accidentally eft open. V

'(5 7 An object of invention is to provide a novel means whereby the fiow of water into the tub is automatically stopped when a predetermined height of water has been drawn into the tub.

Another object is to provide a device of the character stated whichis attachable to the present well known type of plumbing fitting used in modern bathroom installations. i i i A feature of my invention resides in the automatic closure of a valve when the water has reached a predetermined height and then over-flows into a trip chamber.

I Still another object is to provide a novel "3Q tripping means'actuated by the weight of water in a tube which acts to operate "a quick closing valve and thus shut Off the sup ply of water. V Other objects, advantages, and'featu'res of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

In the drawing Y Figure 1 is a front elevation of my automatic over-flow control.

Figure 2 is a fragmentary, transverse, sec tional View of thef'same.

Figure 3 is a fragmentary side View of the tripping mechanismf'and the trip setting means. V y

Referring more particularly to the drawing, the numeral 1 indicates a tube stand which is positioned adjace'ntto the tub and at one end thereof, all in theusual and well known manner understood by those skilled 1931. Serial No. 546,194,

ply pipe 6 and the details of this Valve will be further described. A fitting 8 is attached to the upper end of the ub 1 and this fi ting is alsopr'ovidedwith outlet tap 9 to which avfaucet of usual and well, known design is secured, and thru which the water pours into the tub.

A sleeve 10 is slidably mounted in the tube 1 and when thissleeve-i'is lowered, it rests upon a seat 11 and prevents the water from draining out of the tub. As the. water rises in the tub, and also in the tube 1, it'may flow over the top of the sleeve 10 and thus drain out of the tub, but this drain is suflicient to prevent the tub from overeflowing when the fauce s 3 0r are u ne onthe f ll am u The tub would continue to fill and would eventually over-flow unless the supply of water is stopped. v p i The sleeve 10 is raised and lowered manually bymeans of a'shaft 12 which extends out of the top of the tube 1. The shaft 12 is attached'at its upper end to a .U-shaped link 13, and this link is actuated by the following mechanism: A casting leis secured to the link 13 and the castingis provided at its upper end with a plate 15. A cam 16 is secured to the inner end of a shaft 17 which shaft is rotated by thehandle 18. It will be evident that as the handle 18 is rotated, the cam 16 will move the casting l4 upwardly toraise the sleeve 10 or on further rotation of the handle, the sleeve will be lowered upon its seat. V V

A cylinder 19 is mounted adjacent to the tube 1, and a drain-pipe 20 extendsfrom the bottom ofithecylinder 19 into the fitting 2 so that water will drain out of the cylinder into the sewer.

A basket 21 is slidably mounted in the cylinder 19, and this basket is provided with a small drain hole 22 in the'bottom thereof. b

This drain-hole is not sufficiently large so as to materially efi'ect'the movement-of the] basket when water pours into the top of the same, but merely acts to gradually drain the water therefrom after the water from the main supply has been stopped, as will be furtherdescribed. The basket 21 isopen at the top and water is. adm ted nto the cylin- TES' P TENT-[O ICE I der 19. The port 2& is

sleeve so that water will pour into the 7 cylinder a proper amount in a der 19 thru acolla-r 23 which encirclesthe tube 1 and is attached to the top of the 19. r i

. A port2l extends from the tube 1 thru the collar 23 and thence into the top of the cylinbelow the top of the cylinder 19 beforeit starts to drain over the top ofthe sleeve. thecylinder'19, it will fill the basket 21, thus materially increasing the weight of the basket and, will therefore urge the .same downwardly.

A wire or cable 25 is attached to the basket 21and extends upwardly thru the collar 23. The wire is secured atits upper end to a lever 26 'whichlever is pivotally mounted on an arm 27 which rises from the fitting 8. A counter-weight 28 .is adju'stably mounted on one end of the lever 261 and the purpose of the counter-weight is to slightly over-balance the weight of the basket 21 when empty.:

A roller 29 is mounted on the lever 26' for the purpose of holding the quick closing valve 7 open, in thefollowing manner: A stem 30; extends from'the valve 7 and a cam disc 31' is firmly secured to the outer end of the stem. Y The disc is provided with a shoulder 32 which engages the roller 29 and'thus holds the disc against movement in counter clock-wise direction, asviewed in Figure 3. Thedisc is urged in counter clock-'wisedirection-by means of a spring 33 which is suitably attached to theidisc r a I A coupling'ro'd 3 1 isattached to the disc 31 at its lower end, and to thelink 13 at its upper end. 'This rod is preferably made adjustable as to length so that the disc 31 will be rotated clock-wise direction when the link 13 is moved upwardly. When the handle 18 is operated to raise the sleeve 10 and drain the tub, this same movement will rotate'the disc 31 thru the medium of the rod 3 1 and the counter-weight 28 will swing the lever 26 on itspivot and will cause the roller 29 to engage the shoulder 32.

The spring 33is now intension. "When the disc 31 is in the position shown in Figures 1 and 3, the valve 7 is open to permit water to flow into the tub.

,When it is desired to fill the tub with water,

the handle 18 is rotated andthe sleeve 10 is lowered upon the seat 11. The rod 34 is slidably attached to the disc 31 at its lower end and thus said rod can move downwardly withoutdisturbing the cocked position of the disc.

' The water faucets 3 or a are now opened, and

water flowsthru the intake pipe 6 and into the tub thru thetap 9; WVhen the water starts to'fiow'thru the port 24;, the basket21 is filled and the additional weight of'the water overcomes the counterweight 28 andthe lever 26 is swung on its: pivot to move the roller '29 from under the shoulder 32. The spring As the water pours into.

7 ing an intake pipe, engaging open, means urging the valve into closed posifrom the basket tothe 33 then acts to rotate the disc 31 and the shaft 30 which closes the quick acting valve 7.

In order to drain the water'from the tub,

the handle 18 must be again rotated to raise the sleeve 10, and this action will again open the valve? and cock the disc 31 as previously described.
