Patented Dec. 2, 1930 -UNITED STATES PATENT OFFICE FRANK G. BROTZ, OF KOHLER, WISCONSIN, ASSIGNOR T KOHLER COMPANY, 0F KOHLER, WISCONSIN, A CORPORATION OF WISCONSIN POP-UP WASTE Application med August 6, 1926. Serial No. 127,635.

This invention has for its object to provide a waste fitting for sinks and the like, having a pop-up valve operating on the direct lift principle. j

An object'of the invention is to accommodate the offset relation between the operating means and the Waste valve so as to insure freedom of movement Without loose connections or connections that will work loose or bind or otherwise cause trouble.

Another object is to provide such direct lift pop-up Waste mechanism that will be adjustable verticall and horizontally to adapt it to varying imensions. y

With the above and other objects in view the invention consists in the waste connection as herein claimed and all equivalents.

Referring to the accompanying drawings in which like characters of reference indicate the same parts in different views,

Fig. 1 is a vertical sectional View through a Waste connection, constructed in accordance with this invention; and

Fig. 2 is a transverse sectional view thereof taken on the line 2-2 of Fig. 1.

In these drawings, lOindicates a sink or preferably the dishwasher receptacle of a dish-washer and sink combination of porcelain enamelled construction, having a recess or depression in its bottom forming a waste outlet 11 somewhat larger than usual within which, is clamped a waste coupling 12 having a flaring funnel-shaped open upper end terminating in a feather edge 13 drawn into close fitting contact with the enamelled surface of the receptacleby a clamping nut 14 threaded on the coupling and engaging the bottom of the receptacle with a gasket therebetween. To the reduced neck of this coupling 12 is threaded a waste housing 15 with- 1n which slidably fits a waste plug 16 serving to seal the outlet when in its lower position as shown, but Acapable of being raised to permit the discharo'e of water through its ports 17 when raised 1n a manner well known with op-up waste valves. The housing 15 has an inclined lateral extension carryino` at'its end a vertical guideway in which a plunger rod 18 fits to havevertical movement, said rod 50 having a working fit in the guide both above tion and consequently a special strainer has and below the lateral extension of the housing as well as in its passage therethrough and being protected by a packing gland 19 where it passes out of the upper end of the guide. An inclined connecting rod 2O passes 55 through the lateral extension of the housing and connects the waste plug 16 with the plunger rod 18, so that vertical movements of the latter will be imparted to the former. The lower end of this connecting rod projects through an opening in the Waste plug and its upper end passes through an opening in the plunger rod where it is clamped by a set screw- 21 threaded in the lower end of the plunger rod. This set screw is accessible by removing a screw plug\22 which closes the lower end of the guide. When desired means may be provided for engaging the plunger rod to hold it in its raised position, such means as shown consisting of a spring pressed ball detent contained in a screw plug 23, which is threaded in the wall of the guide, the ball detent thereof being adapted to engage in a recess 24 in the end of the connecting rod 20.

Slidably fitting in an opening in the projecting upper end of the plunger rod 18 is an arm 25 which is held in its adjustment by a set screw 26 threaded in the end of the plunger rod, and threaded through the other end of the arm 25 is a vertical adjusting rod 27 held in its adjustment by a set screw 28 inthe end of said arm. A connecting rod 29 is pivotally connected with the adjusting rod 27 and With the crank arm 30 of a crank handle 31, so that the turning of the handle 3l produces the necessary vertical movements of the waste plug foropening or closing the outlet.

In utilizinga sink or the like container for the purpose of washing dishes, or for cleaning and preparing vegetables, there is likely to'be considerable waste mutter liable to stop up the strainer 0f ordinary construcbeen designed for this,purpose,.particularly to permit of the cleaning of the strainer by making it removable in the form of a basket or container for the refuse matter which may be easily lifted out and carried to a garbage receptacle or other place of deposit. Such strainer is shown in the drawing as a basketlike strainer 32 with an upwardly projecting handle 33 by which it may be carried, there being upwardly extending flaring edges to the strainer tightly fitting against the fiaring surfaces of the coupling 12. Beneath this strainer is preferably a stationary strainer 34, desirably consisting of a perforated disk resting on an internal fiange 35 and also having a handle by means of which it ma be Vremoved when desired. The position o the stationary strainer 34 is sufiiciently above the waste plug 16 to permit of the vertical movements of the latter without interference.

By means of this invention, the sink eutlet lnay be closed to cause it to retain water for dish washing, vegetable washing or other purposes and when the pop-up valve is open by the turning of the handle theenlarged strainer surface will permit of the quick discharge, notwithstanding the presence of refuse matter, such matter collecting in the removable basket-like strainer 32 which may readily be removed and cleaned and when replaced will tightly fit as a plug in its conical 35 from the sink either before or after opening the pop-up waste valve. If there are both heavy solids and fioating solids present it is preferable to remove the heavy solids first and then replace the strainer basket to collect the Heating solids as the water is drained from the container when the valve is opened. In this operation any heavy solids which may have settled into the waste pocket while the strainer basket was removed will be held by the strainer disk 34 and may be removed later.

The construction of the valve operating mechanism is such that there is no possibility of the waste water finding cavities in which to lodge and become foul and there is ne chance for it to escape, but the offset plunger rod parallel with the waste plug and coupled therewith affords a tightly packed medium for connection between the waste plug and f its lifting mechanism. The detent serves to hold the valve in its open position though this may be effected by the usual offset in the connecting rod 29 permitting the crank handle 31 to pass over dead center. The adjustments of the adjusting rod 27 in the arm 25 and the adjustments of the arm 25 in the e plunger rod\18 permit of compensation being made for variations in either vertical or horipop-up waste' without parts likely to become loose to rcquire repair.

IVhat I claim as new and desire to secure by Letters Patent is 1. A pop-np waste valve comprising a housing forming spaced vertical guides with a narrow inclined connection between them, a waste plug having a tubular stem fitting in one guide of the housing and a plunger rod fitting in the other guide of the housing, a connecting rod secured te the plunger rod and engaging in an opening of the stem of the waste plug, a valve seat for the waste plug connected with the housing, and means for lifting the plunger rod to lift the waste plug, the stem of said waste plug being of sufficient length to avoid uncovering the connection between the guides in the open position of the waste plug.

2. A pop-up waste valve comprising a housing forming a pair of' vertical guides spaced apart with an inclined connection between them, a waste plugv having a tubular stem fitting in one of the guides and extending beyond the connection, a valve seat for the waste plug connected with the housing, a plunger rod mounted in the other guide, a connecting rod connecting the plunger rod with the stem of the waste plug and passing through the connection, and means for lifting the plunger rod to lift the waste plug, the tubular stem of said waste plug extending beyond the connection a greater distance than the travel of the waste plug, whereby said connection is not uncovered thereby.

3. A pop-up waste valve comprising a housing forming spaced vertical guides with an inclined connection between them, a waste plug fitting in one guide, a plunger rod fitting in the other guide, a connectin rod passing, through the connection and fitting in an opening in the plunger rod, a set screw in the lower end of the plungerrod for engaging the connection, a screw plug fitting in the lower end of the guide for the plunger rod, said connecting rod passing through an opening in the tubular stem of the waste plg, and means for operating the plunger ro 4. In a pop-up waste valve, a housing forming spaced vertical guides with a connection between them, a waste plug fitting in one guide, a plunger rod tting in the other guide, a connecting rod passing through the connection and engaged with the waste plug and plunger rod, means for operating the plunger rod, and a spring detent engaging the plunger rod for holding it in its raised' position.

In testimony whereof, I affix my signature.
