WASTE-VALVE-OPIERVATING M EANS.

$PECIFIGATION forming part of Letters Patent No. 654,600, dated Ju1y31, i900.

' Application filed April 18, 1899. Serial No. 713,436. (No model.)

Be it known that I, WILLIAM BUNTING, J r., a citizen of the United States, and a resident of New York, (Flushing) in the county of Queensand State of New York, have invented certain new and useful Improvements in- WVaste-Valve-Operating Means, of which the following is a specification.

This invention relates to an improved op erating device for the waste-plug of a basin or bath, which is simple and cheaply made and yet very effective for the purpose intended. V i

Numerous prior devices of this nature have been constructed in which a horizontal reciprocating rod bears against a projection having an inclined surface; 'so that when the rod is forced inwardly the plug is raised and when the rod is withdrawn the plug falls to its seat. These devices have been found unsatisfactory and obj ectionable for several reasons, among the most important of which is the liability of the failure of the stopper to drop after it has been raised and also the neces sity in some cases of providing the sides of the spud with longitudinal gnide grooves for the depending guide of the'stopper. These guide-grooves in the spud are particularly necessary when the stem of the waste-valve consists of a fiat guide or feather, the width of which is approximately the same as the diameter of the spud; This formof guideis very desirable, as it' does not obstruct the waste-passage to any material extent and is strong and very cheaply made. Ithas been found in practice that these guide-grooves are objectionable because in use they become badly clogged, so that the plug cannot be raised or lowered, and, moreover, as these grooves must be'cast inthe spud they must be left rough, as they can only be smoothed up slightly with a file,it being impracticable to plane them out by a machine. In order that this guiding stem or feather may work in anyway satisfactorily, it has been necessary to make the feather fit very loosely in the guide-grooves of the spud,'with the result that the stopper is very imperfectly guided. I obviate these and other defects by my invention, which consists, broadly, in placing the reciprocating rod'at an angle to the hori- 'zontal and providing the plug with a hori-' zontal surface onwhich the rod operates.

My inventionfurther consists in providing the end of the operating-rod with a slot through which the feather or stem passes, so that the said stem will be nicely guided without the necessity of other guiding means being provided.

For a more complete understanding of my invention attention is called to the accompanying drawings, in Which Figure 1 is an elevation partly in cross-section, showing one form of my device applied to a basin. Fig. 2 is a cross-section on the line m a: of Fig. 1. Fig. 3 is an elevation, partly in cross-section, showing a second form of my device. Figs. 4, 5, and 6 are detail views.

Referring to the form of my device shown in Fig. 1, the bowl lis of any well-known form. A vertical push-rod 2, having a handle 3, passes through the slab 4 and the sleeve 5,the latter being secured to the slab in any-well known manner. A bracket 6 is screwed onto the lower end of said sleeve and is locked in place by the nut 7. A lever Sis provided .in the end of said bracket. The spud 9 of the basin is provided with a tubular projection 10, which inclines downwardly from the spud. 'A roll 11 is nicely fitted in said projection 10, and a nut 12, which screws onto the end of said projection, clamps a packingwasher between itself and the end of said projection, so'that there is no danger of leak age about the rod 11. The lower ends of rods 2 and 11 are each provided with a stirrup 13 14, through which the opposite ends of lever 8 pass. The inner end of rod 11 is split by a slot 15, as shown inFigs. 2 and 6, and a pin 16 passes through the rod near the end thereof and across the slot 15.

The Waste-plug 17 is provided with an elon gated flat feather 18, which extends down into the spud O. The thickness of this feather is slightly less than the widthof-the slot 15 and is provided with ahofizontal slot 19, which extends from one side thereof to within a short distance of the other side. Said slot is of slightly-greater width than the diameter therein.

-'To place the plug in its proper position with respect to rod 11, the handle 3 is pulled up to its fullest extent, so that the rod 11 will be Withdrawn to such an extent that the pin 16 is slightly beyond the edge of feather 18. The plug is dropped into the waste-hole at such a" position that the edge of the feather passes into the end of the slot 15 of the rod 11, the pin 16 being set far enough back from the end thereof to permit a positive engagement of the split end of the rod with the feather of the plug at all times when the plug is in position, so that when it is once placed in position it cannot be turned orget out of place unless it is displaced by lifting it up. The operation of this arrangement will be apparent. When it is desired to close the wasteoutlet, thehandle 3 is lifted, drawing the rod 11 outwardly and downwardly, the pin 16, bearing on the under side of slot 19, drawing plug 17 to its seat. When it is desired to lift the plug, the handle will be pressed down.

In the modification shown in Fig. 3 I provide an arrangement of parts which is. for certain reasons somewhat more desirable than that above described. In this figure the rotatable shaft 20 is suitably journaled in the sleeve 20, and the slab is provided with a handle 21 at its upper end and at its lower end with an arm having an upwardly-projecting finger 22. The spud 23 is provided with a tubular projection 24:, which is inclined upwardly from the spud and has the rod 25 located therein. This rod 25 is almost identically the same in construction as rod 11, it being provided with a slotand pin at the inner end, as previously described. Secured to the outer endof rod 25 is a shaft-guide 26, having the elongated opening 27 therein in line with the rod 25. This opening is of sufficient width to permit the shaft 20 to pass therethrough. and of sufficient length to permit the desired lateral movement of said rod 25. Said guide is also provided with a notch 28 at one side thereof, said notch having friction-rollers 29 journaled in each side. The finger 22 is located in said notch, so that when the shaft 20 is rotated it bears against said rollers, drawing the rod 25 outwardlyorforcingitinwardly. Obviously the motion of the guide will be both upward and lateral, the length of arm 22 being sufficient to cause the necessary lateral movement and the length of the finger 22 sufficient to permit the necessary upward movement. The plug 17 and its feather 18 are of the same form as that shown in Fig. 1, with the exception that the notch 19 is made near the bottom of the feather and is cut away at one side, as shown at 19". When the plug is to be inserted, the rod 20 is rotated so that the rod 25 will be forced in as far as possible. The plug is then dropped inplace, care being taken that the feather passes into the slotin the end of the rod and that the outer end of slot 19 in the feather is turned away from the side which the rod enters, so that pin 16 passes through the opening 19" in the slot 19'. The feather 18 by passing through the slot in the endof the rod is securely held against rotation, so that it cannot become misplaced, and as the slotted portion of the rod is arranged in a diagonal position with respect to said stem it engages said stem throughout a considerable portion of its length, so that the rod will securely hold the same in a vertical position when the valve is lifted from its seat. As the stem is thus perfectly guided by the rod, it is unnec-- essary to form guides for the same in the side of the spud. The operation of the modification needslittle explanation. Then the handle 21 is turned so that the rod 25 is drawn outwardly and upwardly, the plug will be lifted and will again be lowered when the handle is turned in the opposite direction.-

The construction shown in this figure is somewhat more desirable than that shownin Fig. 1, for the reason that the plug is guided somewhat better and because it has the tubular projection 24 inclined upwardly instead of downwardly, whereby all danger of leakage around the rod 25 is avoided. By having the operatingrod inclined upwardly from the waste-pipe I can also arrange the operating means very compactly. The most important advantage resulting from the arrangement of the operating-roddiagonally of the Valvestem is that it provides a perfect guiding means therefor, so that it is unnecessary to provide the spud with internal guides such as have before been necessary. I am thus enabled to bore out the spud after it is cast, leaving the passage perfectly smooth, so that there is no danger of threads, hair, and othermatter catching therein.

It will thus be seen that I have provided a waste-valve-operatin g means which is simple and durable and unlikely to get out of order.

My invention may be applied to the valve of a bath-tub or sink, as will be obvious.

Having described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is as follows:

1. A water-receptacle having a waste-outlet, a waste-pipe connected thereto, a waste stopper therefor, a stem secured to the under side of said stopper, said stem being flat and of substantially the same width as the inter nal diameter of the waste-pipe for a portion of its length, and having a laterally-arranged lower edge, a rod which passes downwardly into said waste-pipe, in a diagonal direction, a longitudinal slot in said rod, which is of substantially the same width as the thick ness of the flattened portion of the stem and and means for reciprocatingvsaid rod so that said stopper will be simultaneously lifted and guided thereby.

2. A water-receptacle having a waste-outlet, a waste-pipe connected thereto, a wastestopper therefor, a stem secured to the under side of said stopper, said stein being flat, and of substantially the same width as the internal diameter of the waste-pipe, a slot cut in said stem which extends from one side of said stem to a point near the oppositeside thereof, and having the upper side thereof SUbSlflll tially horizontal, an inclined rod which is bifurcated at its lower end, and which passes diagonally on each side of said stem and engages each side thereof, a pin in the end of said rod which is arranged to engage the upper side of the slot in said stem, and an operating-handle connected to said rod for drawing the same upwardly.

3. A water-receptacle having a waste-outlet, a waste-stopper therefor, a guiding-stem secured to the under side of said stopper, said stem being flat for a portion of its length, and having a laterally-arranged lower edge, a rod having a slot in the end thereof, a bar in the end of said rod which crosses said slot and is adapted to engage said lower edge, said flattened portion of said stem being fitted in said slot and the slotted end portion of said rod being arranged diagonally of said stem, and means for drawing said rod outwardly from said pipe, whereby said stem may be simultaneously lifted and guided.

4. A water-receptacle having a waste-outlet, a waste-pipe connected thereto, a wastestopper therefor, a stem secured to the under side thereof, said stem being fiat and of substantially the same width as said waste-pipe for a portion of its length and having a substantially-horizontal edge, an inclined rod which passes through said waste-pipe and has its lower end bifurcated and passing diagonally on each side of said stem and engages each side thereof, a pin in the extreme lower end of said rod which crosses the bifurcation thereof and which is arranged to engage said horizontal edge.

5. A water-receptacle having a waste-outlet, a waste-pipe connected thereto, a wastestopper therefor, a stem secured to the under side of said stopper, said stem being fiat, and of substantially the same width as the internal diameter of the waste-pipe for a portion of its length, an arm which extends laterally from one side of said stem for a portion of the width of said pipe, thereby forming a laterally-extending slot between said stem and said arm, an operating-rod which enters said pipe at a point adjacent the side of said stem from which said arm extends, said rod being provided with a bifurcated end which is arranged diagonally of said stem, and closely engages the opposite sides thereof, a bar in said rod which crosses said bifurcation and is adapted to engage the upper edge of said slot, and means for reciprocating said rod at an angle to said slot, whereby said stopper may be simultaneously lifted and guided and be locked against removal when it is lifted from its seat.

In testimony whereof I have affixed my signature in presence of two witnesses.
