MICHAEL J. TRACY, OF ST. LOUIS, lvSSOUR SAFETY FLUSHING APPARATUS Application led November 28, 192'?. Serial No.

rlhis invention relates to safety liushing apparatus having equipment to prevent adjustment or manipulation thereof to cause flooding and overflow.

It is aV matter of knowledge that inmates of institutions, such as penal institutions, sometimes cause damage to the institutions by flooding the saine trom the flushing apparatus to which the inmates have access. This is caused by obstructing the waste outlet Jfrom the liushing apparatus and adjusting` or manipulating the valve controlling the admission of water to the apparatus, so as to permit a continuous ilow of water into the app'aratus. The result is that the apparatus is overlowed because a greater vo-lume of water isvk admitted than can pass through the waste outlet. Much damage has been caused in this way and the problem has arisen ot designing means for preventing adjustment or manipulation of the apparatus by the inmates of the institutions whereby damage is caused, as stated.

An object of the invention is to provide means for preventing successive operations of the valveafter the latter has been operated once for flushing the apparatus. This means tor preventing successive operations of the valve is combined with the apparatus in a. place and position inaccessible to the inmate, so that it is impossible for the inmate to tamper with said means.

Another object of the invention is to indicate which flushing apparatus has been obstructed so that the source of trouble may easily be located. lVhile this information may be given in different ways within the scope ot the present invention, the means by which I have chosen to give the information is by causing an overflow from the flushing apparatus of a part of the excessive amount of water admitted thereto without permitting such overflow to cause damage to the institution.

Other objects will appear from the following description, reference beingmade to the accompanying drawings in which Fi-g. l is a pla-n view of a flushing apparatus 5' embodying the present invention.

Fig. 2 is an enlarged ver vical sectional view on the line 2 2 ot Fig. l.

Fig. 3 is a rear elevation of the. invention.

Fig. 5 is a vertical sectional view on the line 5 5 of Fig. l.

ln the embodiment of the invention shown, the flushing bowl l has a continuous chamber 2 around its upper portion. The bowl l is provided with the usual waste outlet la. This chamber 2 receives the flushing water and discharges the same downwardly into the bowl through slots or openings 3 (Figs. 2 and 5).

A water supply pipe l from a source of supply opens into a valve 5 from which a pipe 6 entends and communicates through a chamber .7 with the chamber 2. A valve S in the pipe 4 is adjustable to open and to close said pipe and also to vary the amount of water permitted to pass through said pipe to the flushing apparatus. A wall 9 separat-es the bowl l from the water supply connections described, so that it is impossible for the inmate ot the institution having access to the bowl to tamper with any of the water supply equipment.

Within the valve housing 5 a valve of known or approved construction is mounted, and is capable of being opened by manipulating a stem l0. rlhe valve device 5-10 shown is of the Sloan type and it is well known that movement of the stem l()` laterally in one direction will open the valve. This fact being well known, it is deemed unnecessary to illustrate other details ot this valve beyond lche devicefor manipulating said stem.

The device for manipulating the stem 10 to open the valve in the housing 5 toY flush the bowl, comprises a stem il mounted in a support 12. The stem 11 entends through and is guided by a partition 13 in the support l2. This stem ll is capable of longitudinal movements and is actuated outwardly in a direction away from the stem l0 by a spring lil encircling the stem and having its inner end bearing against the partition 13 and its outer end bearing against a collar l5 on said stem l1. Outward movement of the stem 1l is Cil limited by a collar or ring 16 attached to the stein 11 at the inner side of the partition 13. The support 12 opens through the wall 9 to the compartment of the inmate having access to the bowl 1 and is provided on its inner end with a push button 1.7 whereby said stem may be actuated in opposition to the spring 14. Movement of the s em 11 by the button 17 in opposition to the spring 14 and toward the stem oscillates said stem 10, with the result that the valve in the housing 5 is opened to permit passage ot water to flush the bowl 1.

My present invention comprises means for locking or preventing further or other operations of the valve stem 11 and thus permitting the valve in the housing 5, which is controlled by the stem 10, to close and remain closed after each flushing operation. For this purpose I provide a float receptacle 18 arranged to receive water from the chamber 2 whenever the bowl 1 is flushed. A pipe 19 opens into the chamber 2 and inclines downwardly to an opening into the receptacle 18. A tube from the upper end of the receptacle 18 opens into the valve stem support 12. A float 21 in the receptacle 18 has a stem 22 extending upwardly within the tube 2O and being' of such length that the upper end ot' said stem is below the inside of the support 12 when the float 21 is at the bottom of lthe receptacle 18. When water flows into the receptacle 18, as a result of the iiushing of the bowl 1, the float 21 is raised, moving the upper end of the stem 22 into the support 12. The stem 11 has a collar 23 forming an abutment thereon. W'hen the stem 11 is in the position in which it is moved and held by the spring 14 and to which it must be moved at each flushing operation, the collar abutment 23 is at one si le of the opening to the tube 20, so that the water in the receptacle 18 will raise the float 21 to project the upper end of the stem 22 at the side of the abutment 23 and prevent any other or additional operation of said stem, after ene flushing operation thereof. The construction is such that the abutment 23 will form an obstruction and prevent the stem 22 from extending into the support 12 when the stem 11 is out of the position to which it is moved and in which it is yieldingly held by the spring 14. Thus, since it is necessary for the stem 11 to return to its normal position, in which it is yieldingly held by the spring 14 in order to perform a flushing operation, it must be apparent that the stem 11 is locked as a result of each flushing operation and cannot be operated until the stem 22 is withdrawn from the support 12. The stem may be withdrawn from the support 12 by withdrawing the water from the receptacle 18. For this purpose, I provide a drain valve 24 for said receptacle. This drain valve 24 is normally closed, and it is intended and required that the same be opened after each flushing operation of theapparatus before another flushing operation can be performed.

As shown (Fig. 1) the wall 9 forms an alcove in which the bowl 1 is located. A metallic plate 25 extends across the front of the alcove. Said plate 25 extends upwardly from the floor, across the front of the alcove and has a horizontal extension 26 into the alcove and provided with an opening to the bowl. A gaslet 27 is seated in a groove (Figs. 2 and 5) in the upper wall of the chamber 2 and -is clamped by the horizontal portion 26 of the plate 25. This gasket is impervious to water and moisture and forms a seal to prevent the passage of water under the plate 25-26, and also prevents accumulation of desposits in the space in which the gasket is mounted.

Above the plate 25 is the alcove a dished plate 28 is secured, the same having a downwardly curved flange 29 across its front edge extending below the upper edge of the plate 25 and spaced therefrom to provide an opening 30 (Fig. 5). The upper dished portion of the plate 28 has a central opening above the bowl 1 provided with a marginal downwardly curved flange 31 spaced from the edge of the opening through the horizontal plate portion 26 to leave a space 32, through which water may iow when the bowl becomes illed to a depth above the plate portion 26. The water owing under the plate 28 passes through the opening 30 to the cell, compartment or room occupied by the inmate who flooded the bowl.

1t is now clear that the water for liushing the bowl 1 enters the chamber 7 from the pipe 6; and that from the chamber 7 the water is discharged into the chamber 2 and thence through slots or openings 3 into the bowl. 1t

is also clear that the pipe 19 forms communication 'from the chamber 2 to the receptacle 18, so that when the water rises in the chamber 2 to a height sufficient to overflow from said chamber through the slots or openings 3 a part of said water in the chamber 2 flows through the pipe 19 into the receptacle 18. Accordingly every time the bowl is flushed water passes from the chamber 2 through the pipe 19 into the receptacle 18 and raises the float 21 and thereby the stem 22 so as to place the upper end of said stem 22 across the path of movement of the abutment 13, as shown by dotted lines in Fig. 4. The float 21 will be sustained by the water in the receptacle 18 until the valve 24 is opened to drain water from the receptacle 18. Therefore, every time the bowl is flushed the float 21 is raised and the valve stem 11 is blocked against a subsequent operation until the receptacle 18 is drained. This is not dependent upon any obstruction inthe waste outlet 12L but occurs automaticallyand as an incident to each operation of the valve stem 11 to flush the bowl.

'1,81 assai as an incident to each operation of the valve stem l1 to ush the bowl and as previously described, the valve operating siem 11 became locked when the stem 22 was raised by water entering the float compartment 18. Thus, as an incident to the flushing ot the bowl, the stem ll is locked against successive opera ion. And, if the bowl is flooded by an obstruction in the waste outlet la a quantity of the excess water overflows into the cell or compartment of the inmate who caused the flooding, so that detection of the one whose bowl was flooded is easily obtained.

I am aware that the construcion, arrangement and relationship oi the parts may be varied without departure from the nature and principle of the invention. I do not restrict myselrn unessentially in any respects, nor otherwise than as set forth in the appended claims.
