VALVE MECHANISM FOR WASH-BASINS.

SPECIFICATION forming part of Letters Patent No. 484,423, dated October 18, 1892.

Application filed April 20, 1892. Serial No. 429,878. (No model.)

To all whom it may concern:

Be it known that I, JAMEs WHITE HALE, a citizen of the United States, residing at Newbnryport, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Valve Mechanisms for Wash-Basins, of which the following is a specification.

This invention is an improvement upon and contains certain parts embodied in the inventions for which Letters Patent of the United States were granted to me November 4,1890, numbered 439,818, and April 28, 1891, numbered 451,324.

The nature of this invention is fully described below, and illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of portions of a basin or bowl provided with my improved valve mechanism, the latter being shown in elevation and in the position assumed when the valve is open. Fig. 2 is an enlarged view partly in elevation and partly in vertical section, the valve being closed and the bowl removed. Fig. 3 is an enlarged cross-section taken on line 00, Fig. 1, looking up. Fig. 4 is a plan View of the ring P, below described. Fig. 5 is an enlarged cross-section taken on line y, Fig. 1, looking up, themarble and portion of the bowl having been removed. Fig. 6 is an enlarged plan view of aportion of the under side, a part being shown in horizontal section on line 2, Fig. 1. Fig. 7 is a side elevation of the connecting-hook K K K. Fig. 8 is an elevation illustrating a modification of the guide-tube N and flange.

Similar letters of reference indicate like parts.

A represents the basin or bowl, provided with the ordinary overflow-holes a, leading to the overflow-passage A, extending therefrom to the waste-pipe.

B is the marble top.

0 is the waste-pipe, (see Fig. 2,) externally screw-threaded at C and pushed down into the bowl, being held in position therein by the flange O and the coupling-pipe nut D, said nut being integral with the coupling-pipe D, Figs. 1 and 2, and prevented from coming into actual contact with the bowl by the flange D and the flexible washer d, Fig. 1. The coupling-pipe D is not in direct contact with the waste-pipe C, but is separated from it by internal ribs d, integral with said pipe D, similar to those lettered din Letters Patent above referred to and numbered 451,324.

E is a sliding pipe or tubular valve-stem provided externally with the vertical ribs E, Figs. 2 and 3, and internally with the two projecting ribs E, Figs. 3 and 6, which are rigidly connected together at the top by means of the cross-bar e.

The lower portion of the pipe E is provided externally with the flange 6. The internal projecting ribs E and the external ribs E" and flange e are all rigidly secured to or integral with the sliding pipe or tubular valvestem E.

F is a circular valve of sufficient diameter to close the water-passage in the waste-pipe C, said valve being provided on its under surface with the pin or bolt F, Fig. 3, screwed into a centrally-located hole in the cross-bar e, therebyholding the valve and sliding pipe or tubular valve-stem together.

Within the waste-pipe C, and but a short distance below the level of the flange C, Fig. 2, is a ring P, provided internally with a slight projection or teat P ,Figs. 3 and 4, and externally screw-threaded, so as to engage the corresponding threads on the inner surface of the waste-pipe O, and by means of which it is screwed down the waste-pipe and held firmlyin positiontherein. Between the ring P and the sliding pipe or tubular valve-stem E is a spiral spring S, which presses up against said ring and down upon said sliding pipe E, thereby tending to force them apart, and in so doing bring the valve F down firmly against the upper face of the flange 0, forming a water-tight joint. The internal projecting ribs E extend up through both the spiral spring S and ring P to the valve F, as shown in Figs. 1 and 2. The coupling-pipeD is provided with the hollow substantially-horizontal extension D into which (by means of an internally-screw-threaded hole) thehollow plug I is screwed.

H is a lever curved at 1-1 and terminating at that end in acurved disk or face H,which comes in contact with the farther side of the bottom of the sliding pipe E. The opposite end of this lever is rigidly secured to the flange h, rigid or integral with the rocking shaft H, having its hearings in the tubular plug I. (See Fig. 6.) With this rocking shaft is also connected the rod J by means of the head J. The flange h, rocking shaft H, tubular plug I, and the head or end J of the connecting-rod J are all essentially the same as shown in my patent of November 4, 1890, numbered 439,818, except in the following respects: The tubular plug I is counterbored, as shown, so as to form an internal chamber of sufiicient size to receive the spiral spring R, which surrounds the shaft H and presses against the internal flange or annular shoulder I and the head or end J of the connecting-rod J, which projects a short distance into the internal chamber, and being secured rigidly to the rocking shaft I-I turns with it.

It will be seen that the action of the spring R is to hold the internal flange or annular shoulder I and the flange h in close contact, thereby preventing leakage without any possibility of the parts binding or working hard, as is apt to be the case when only the nut h is used to keep them in contact. The .opposite end of the connecting-rod J is attached to the lifting-rod L by means of an engaging hook, Figs. 1 and 7, the backbone K of which is vertically perforated and internally screwthreaded to receive the correspondinglythreaded portion L of said rod L. The portion K of said engaging hook is provided with the lower horizontally-projecting spur K and the upper spur K, the latter being bent downward into a hook shape, as shown. The upper part L of the lifting-rod is of larger diameter than the lower portion and is provided with screw-threads, so as to receive the check- I nut Z and lock-nut Z. A locking-pin Zprojects rigidly from the portion L of the lifting-rod, as shown. mounted by the button L and slides vertically in the guide-tube N, said guide-tube be ing recessed away at n, so as to leave the shoulders N and N, and being held in position in the marble B by means of the flange N and nut n. \Vithin this guide-tube, e2;- tending vertically from bottom to top, is the slot at, Fig. 5, adapted to receive the lockingpin 1 and to allow it to pass up through the tube.

When the valve is open, as shown in Fig. 1, the process of closing is as follows: The bot ton L is turned round in such a manner as to bring the locking-pin Zawayfrom the shoulder N and over against the shoulder N, in which position it is exactly under the slot at. The spring S forces the sliding pipe E down and with it the free end of the lever H H 11', thus rotating the shaft A and raising the outer end of the connecting-rod J, which lifts the hook K K K, and hence the rod L L, forcing the locking-pin up into the slot '21., thereby closing the valve F and bringing the check-nut Z up against the shoulders N N. To close the valve, the process is reversed by pressing the button L down and turning it round, so as to bring the locking- The lifting-rod is surpin out from under the slot 'n and against the shoulder N.

It will readily be seen that when the checknut Z and lock-nut l are placed too far up on the rod L the valve will be checked be fore it is quite closed and rendered leaky; but if the nuts are too far down the rod the button L can be pulled up some distance after the valve is closed, which gives rise to considerable lost motion.

In the modification shown in Fig. 8 the guide-tube N (said guide-tube being lettered in this figure W) has a non-integral flange W, and the internal slot W is cut entirely through. The tube W is provided with the flange W which prevents it from being pulled through the loose flange W. In other respects it does not difier materially from the guide-tube shown in Fig. 1.

Inorder to clean the valve, it is first thrown into the open position shown in Fig. 1. Then the valve F is unscrewed and the cross-bar e grasped between the thumb and fingerand turned in the same direction in which the valve is turned, thereby bringing one of the internal projecting ribs in contact with the teat P, causing it to revolve and thus unscrewing the ring P from the waste-pipe C and liberating the spring S and sliding pipe or tubular valve-stem E. After the parts are cleaned they are replaced in the following manner: The spring is slipped over the crossbar e and projecting internal ribs E. Then the ring P is slipped into place above the spring and the valve is screwed into the cross-bar e. The button 11' is then turned around, pulled up, and held in a raised position, the spur K raises the connecting-rod J (the end of which dropped down upon the spurK when the spring S was removed from the waste-pipe O) and depresses the inside lever H, and the sliding pipe E, with the spring S, ring P, and valve F all in place upon it, is then pushed down into the wastepipe G and turned around until the threads on the ring or washer P engage those on the inside of the waste-pipe O. The valve can then be opened and the ring P screwed into place.

The principal advantages secured by this invention are greater cleanliness, lightness, and compactness, ease of working without any danger from leakage, and freedom from strain, as any undue force applied to the button L is expended on the draw-tube N, shoulder N, nut Z, or pin Z, thereby preventing the bowl A, valve F, and intermediate parts of the mechanism from injury.

The bend at H in the lever H enables the box containing its fulcrums to be placed near the Waste-pipe and the external ribs E on the tubular valve-stem allow ample space for the descent of dirt, &o.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In combination with the connecting-rod IIO J and lifting-rod L, the engaging hook eonthe ring P, provided with the projection P sisting, essentially, of the backbone K, lower for engaging said ribs, substantially as set 10 extension K, and upper downWardly-projectforth.
