POP-UPWASTE VALVE Filed Jan. 28, 1946 Patented Feb. 15, 1949 POP-UP WASTE VALVE- Marvin F. De Grave and J osephCalladine; Salem, Ohio, assignors to Elton-Company, Ford City,
Application January 28, 1946, Serial'No. 643,898
13 Claims. (Cl. 4-198) This invention relates to lavatory pop-up waste valves for wash basins and the like.
It is an object of the present invention to provide certain new and useful improvements in the means for moving the valve in opening and closing the same.
A further object of the invention is to'provide for automatically holding the valve in the closed or any open position to which it may have any selected open position.
' Another object is to provide for the convenient assembly'of the valve operating means with the valve casing.
The improvements of the present invention have been designed for use in connection with the conventional type of pop-up waste valve and been moved, thereby to maintain the valve in may be installed without requiring any change in the conventional manner of clamping the valve 1, casing upon the wash basin, and without alter- I ing the conventional valve and valve stem. In this connection it is proposed to provide for the convenient assembly of the valve casing and a nut employed for clamping the casing tothe wash basin.
The present invention employs a conventional valve actuating lever having the conventional circular enlargement to be used as the fulcrum portion thereof. According to the present invention the'circular fulcrum portion of the lever is housed within a tubular nipple or fitting in such a manner that the lever and nipple may be conveniently assembled and thereafter may be engaged with the valve stem and the nipple connected to the valve casing while the nipple and lever are in assembled relation, thus simplitying the association of these parts.
Provision is also made to maintain the circular fulcrum portion of the lever under a yielding pressure such as will permit swinging of the lever on its fulcrum for manipulation of the valve,
While at the same time exerting pressure .on the circular portion sufficient to hold the lever in' 2 the appended claims; without departing from the principles of the present invention.
In the drawing,
Figure 1 is a longitudinal sectional view of a conventional pop-up valve having the improvements of the present invention applied thereto;
Figure 2 is a detail sectional view on' the line 2 2 showing the manner of assembling the clamping nut with the valve casing, the valve actuating lever and supporting nipple being removed.
In the accompanying drawing, the reference numeral I indicates a conventional form of popup valve casing which is in the form of a tube open at opposite ends. The lower open end of the casing is screw threaded for connection with a waste pipe in the ordinary conventional manner. The upper end of the valve casing is provided with an annular flange 2, as usual, for engagement with the upper face of the bowl, Below the flange, the valve casing is provided with slots or openings 3 to permit overflow water to enter into the interior of the valve casing. Below the openings 3, the Valve casing is exteriorly threaded as at 4 for engagement by a clamping or retaining nut 5 for pressing a gasket 6 against the bottom of a wash bowl.
Within the casing is a tubular open ended valve stem 1 having a working fit Within the casing and carrying at its upper end any suitable form of valve head or member 8 for closing the open upper end of the valve casing l. The stem is provided with slots or openings}! in its upper end portionfor registration with the side openings 3 in the valve casing so as 'to admit overflow water into the interior of the tubular stem "I, the latter being open at its lower end to permit of the escape of waste water and overflow water into the waste pipe. The tubular valve stem 1 is raised and lowered by means of a lever 10 havingits inner end received within an opening it in a wall of the tubular valve stem 1. The outer end of the lever is intended to be connected with any conventional or preferred formof means for rocking the lever in a vertical plane. As is common practice the'lever is provided with. a spherical enlargement l2 constituti'ng'the fulcrum portion of the'lever. The parts thus described are conventional and form no part of the present invention.
In carrying out the present invention, there is provided an open ended tubular fitting or nipple l3 within which works the inner end portion and the spherical fulcrum portionof the lever. The valve casing l is provided with an opening id to accommodate the inner-end ofthelever, and
3 7 permit the necessary up--and-down movement thereof. Surrounding this opening is a circular flange or boss l with which the inner end of the fitting or nipple It has a screw threaded connection. A suitable packin ring It is provided between the outer end of the flange l5 and an annular shoulder l! provided upon the nipple so as to provide .a water tight joint atthis point.
Before connecting the nipple I3 to the valve casing, the outer end portion of the lever Ill is passed through the inner open end of the nipple and out through the outer open end thereof :until the spherical portion l 2 engages an inner annular flange l8 provided upon the nipple and reducing the interior diameter of the latter at this point so as to prevent outward passage of the spherical part l2 and thus prevent separation of the parts in an outward direction. Suitable packing i9 is introduced through the open inner end of the nipple and arranged around the spherical part l2. A packin gland "2%? is then introduced into the nipple and against the packing. A spring 21 in helical form is then placed against the gland, and asplit spring retaining ring 22 is introduced into the nipple and snapped into an annular groove 23 provided in the inner-wall of the nipple.
It will here :be explained that the lever, the packing, the gland, the spring and the retaining ring, may all be conveniently introduced into the nipple through the inner end thereof, and when the parts have thus been assembled, the spring will exert pressure on the gland through which pressure will be applied to the packing and then to the spherical portion l2 so that said spherical portion will be held against the flange 18 and will be under yielding pressure exerted by the spring 2|.
The valve casing is assembled with a lavatory wash bowl in the usual manner prior to placing the nipple 13 upon the casing by thrusting the casing downwardly through the usual opening in the base of the "bowl commonly provided for this purpose and the nut :5 is then :set up against the gasket ll to clamp the bottom of the bowl between the flange 2 and the nut. .It 'will, of course, be understood that the nut is assembled with the valve casing and set up tightly against the gasket prior to assembling the valve operating means with the casing and the valve stem. I In order to facilitate the assembly of the nut E5 with the valve casing 1,, the threaded bore of the nut is provided with a notch 24 extending entirely across the bore and opening through opposite faces of the nut. The notch is of such size and shape as to permit of the passage therethrough of the flange I 5 when the not has been slipped upon the exteriorly unthreaded end portion of the valve casing and moved along beyond the flange 15 so that it may be engaged with the exteriorly threaded and somewhat enlarged por tion 25 of the valve teasing and then screwed tightly against the end of the gasket 6. The notch (24 is large enough to permit of the passage therethrough of the flange 15, thus leaving a length of screw threads in the bore of the nut sufficient to enable proper engagement of the threads of the nut with the threaded portion 25 of the valve casingto enable the setting of the nut against the gasket'fi. The external diameter :of the exteriorly unthreaded valve casing portion is slightly less than the diameter of the bore of the nut, so as to enable the quick and convenient assembly of the nut and valve casing.
Any suitable connection may be provided between the outer end of the lever and the casing, a valve stem working in the casing, said casing having-an exteriorly screw threaded portion and provided with an opening located between the screw threaded portion and the outlet of the casing, said opening having an outwardly directed circular flange, a retaining out for en-- gaging the screw threaded portion of the casing and provided in its bore with a notch opening through opposite faces of the nut andthrough which notch the flange may pass when the nut is being assembled with the casing preparatory to engagement with the threaded portion of the casing, and valve stem operating means carried by the flange and having a lever extending through the opening in the casing and into operative association with the valve stem.
