DIVERTER VALVE Filed NOV. 28, 1934 INVENTOR5 Patented May 19, 1936 UNITED STATES PATENT OFFICE DIVERTER VALVE Application November 28, 1934, Serial No. 755,108

14 Claims. (01. 251-76) This invention relates to an improved spout with a diverter valve particularly adapted for use in a plumbing fixture to divert water normally issuing to a bath tub through the usual spout,

and to cause it to flow through a shower arrangement above such tub. The valve is of the type which is held in diverting position by force of the pressure of water passing through said spout, and is so devised that it is moved to diverting position by said pressure when a latch is released and returns to latched position when the flow of water is cut off. We have arranged our valve within a spout which is tapped on the upper side for inserting a pipe to support and supply water to a shower device. This permits the substitution of our valve-carrying spout for a spout of the usual type, and. the addition of shower equipment, without need of access to the apparatus for mixing hot and cold water which apparatus is usually concealed.

In the drawing:

Fig. l is a view of a spout containing our valve with the interior parts shown in phantom; Fig. 2 is a view of the valve plug and the trigger which controls it; Fig. 3 is a view of a shower in position over a tub showing one relation of our spout and valve thereto; Fig. 4 is a view of the latch.

Referring to the drawing, the tub I, a portion of which is shown, is of the usual type and pro-; vided with a mixer (not shown) in which the desired temperature of water is secured by manipulation of hot water and cold water valves in a manner well understood in the art. The tempered water is discharged through a spout shown 35- mounted through the wall of the tub. In Fig. 3 a spout 2 containing the diverter valve of our invention is shown with a shower arrangement affixed by the pipe 3 in the threaded opening 4 of the spout.

.A spout containing our diverter valve is shown in Fig. 1. Said spout 2 has a collar 5 and a threaded opening 6 for attachment to the pipe discharging tempered water into a tub, and has a threaded vertical opening 4 on the upper side for the insertion of a pipe 3 supporting, and supplying water to, a shower 8. Through the spout is the usual passage 9 which we finish in part with a smooth cylindrical surface for cooperation with a valve plug l0 hereinafter described. Beneath the passage 9 and within the wall of the spout is a by-pass channel H, the forward end of which is open to the passage 9 as shown at l2. At the rear of the channel is an opening l3 communicating with the passage 9. Mounted on top of the spout forward of the opening 4 are two vertical ears l4 between which in the spout wall is a slot l5. An angular lever i6 is mounted between said -ea.rs M by a pin 11 therethrough. The short element l8 of said lever is held in said slot I5 and in engagement with the valve plug I II as will be explained. The long element l9 terminates in a small weight 20. Forward of the ears I 4 a latch 2| is pivctally mounted transversely of the spout in a position to receive the long arm I9 of the lever, by which it is actuated to latching position holding said arm against movement.

Said latch as shown in Fig. 4 comprises two arms 5| and 52 upturned on either .side of a pivot-pin 53. The arm 5| is hook-shaped-and has a projection 54 whereby it is moved to release the arm I9. To secure automatic latching in case the latch is tilted to latching position when the lever element I9 is free, the upper surface 55 0f the hook and projection is so inclined that the descending arm l9 will move the latch to open position when it encounters said inclined surface. On the inside surface of the other arm 52 is an inclined surface 56 adapted to receive the descending lever element l9 which will thereby move the latch to operating or holding position as shown at 51. To retain the latch in this position until released by manual operation the arm 52 is weighted. The valve plug I0 is snugly fitted within the finished portion of the spout passage 9. On the upper side of said plug is a hole 22 which engages the short arm ill of the lever l6. This hole 22 is in the forward end of the plug III which end is solid. The rear portion of the plug II] has an interior longitudinal passage 23 open at the rear and closed at the forward end by the solid portion of said plug. A transverse slot 24 in the under wall of said plug communicates with the interior passage 23 just back of the solid portion of said plug. This slot 24 is so positioned as to be moved over the opening l3 between the interior passage 9 of the spout and the bypass channel II when the plug is held in locked position by the lever Hi and the latch 21. In the upper Wall of saidplugnear the rear end thereof is an opening 25 communicating with the interior passage 23, which opening is so positioned that it underlays theopening 4 in the spout wall when said plug is freed by the latch and moves to forward position under. the pressure of the water flowing thmugh the spout.

In operation the spout will provide a clear passage for water therethrough when the plug is latched in the position shown in Fig. 1. Water entering from the mixer will flow through the passage 9 until it encounters the plug In, it will V 25 i -Fig. .3.

2", x flow through the passage 23 in said plug and pass through the apertures 24 andl3 into the by-pass channel H and escape through the opening I2back to the main spout passage 9 and into' the tub.

But, when the latch 21 is tilted and the arm [9 released after temperingthe flowing, water to the temperature desired, theforce of the water acting against the solid portion of the plug will move the plug forward, closing the opening l3 into the by-pass channel and moving the opening'25 beneath the opening 4 whereby the water will escape through the shower arrangement. 7

When the water turned off, the weight 5 through the lever IE will move the plug backward to the initial position and the latch 2l will be 7 actuated by the descending arm, l9 which it will engage and hold, leaving the valve in condition for mixing and tempering the flowing water 20 before the shower is again used.
