Application filed April 5, 1927. Seria1 No..1 S1,1 08. I

This invention-relates to certain new and useful improvements in -'fiushing mechanism of the type wherein the flushmg mechanism is operativelycontrolled by the pressure of the closet seat, and particularly to that class of flushing mechanism of the stated-type in I which valves control the flow of water from a supply pipe to a closed tank herein the contained air is compressed, ancltronr'thenoe to the hopper or bowl for theflushing action.

The invention more particularly relates to afiushing mechanism of the character set forth wherein theflush'water is admitted directly to the upper rear portion of the bowl through the medium of a seat-controlled valve mechanism mounted directly upon the bowl. I v

The primary object of thep resent'invene tion is to provide a flushing mechanism in which valves arearrangedwithin a casing to the valve mechanism as a whole is so mounti'emoval for cleaning, repairs and renewal of parts as occasionrequires in service.

A further object of the? invention is to provide a flushing mechanism which is ofmaximum simplicity of construction, reliability and efliciency in action, which is comparatively inexpensive of production and installati on, which is composed of comparatively few parts, and which dispenses with a valve cage and is devoid of complex stuffing elements or other parts easily subject to wear or liability to clog or get out of order.

A San further :ob ectot the invention is to provide-a valveoperating mechanism which is automatically adjustable or variable in action to compensate {for wear of a valve- ,element. .f V

A still further object of the invention is to provide novel means I for attaching the seat bracket to therock shaft of the valve mechanism, which means may be adjustable to vary the throw of the shaft for'wear compensatingactions i i The invention consists'of the features oi" construction, combination and arrangement of parts, hereinafter fully described and claimed reference being had to the accompanyingdrawings, inwhich v Figure 1' is a side elevation showing the application of the'fiushing mechanism to a bowl and the'seat in normal'position.

Referring now more particularly to the drawings, 1 designates abowl of: any ordi- I naryor preferred construction which is-provided at its upper rear portionfwith aneX:

throughthe top of the evtension 2.

Fitted at itsylow'er end within the said opening in the top otflthe extension 2is a valve casing 41; havingat its lower e'nd an mternally threaded aperture within which is fitted the externally threaded upper end of: a

detachable valve casing discharge and guide extension 5 which opens at'its upper end into the bottom of thecasing 4 and is providedlat annular abutment shoulder 1 and abovesaid shoulder is formed with an annular series of water discharge ports8 communicatinggdirectly with the passage 3. At'its saidglowe'r itslower end with a guide opening6 and an end the valve casing is provided with a supporting flange 9 which rests upon a asket or washer 10 seated upon the top of t 1e extension 2 about the inlet opening of the water passage therein, and forming an air and water-tight connect-ion between the two, said flange and gasket being perforated for the passage of bolt-s or similar fastenings 11 whereby the valve casing is mounted in position upon the bowl.

The valve casing is provided at its upper end with externally and internally threaded nipples 12 and 13 which are in direct communication with each other and in communication with the body of the valve casing through a. port 14 in a partition 15. The nipple 12 provides a water feed or supply inlet which receives the lower end of the vertical arm of an L-shaped connector, union or fitting 16, providedwith an annular flange 17 against which bears a clamping nut 18 engaging the nipple whereby said connector is detacliably secured to the valve casing, packing 19 of a suitable kind being introduced between the flange 17 and the nipple to make a water-tight connection. The lower end of the vertical arm of the nipple is formed with a valve seat projection 20, andthe free end of the horizontal arm of the connector, which extends rearwardly from the valve casing, is providedwith an annular externally threaded coupling head or enlargement 21 to receive a nut 22 which detachably couples said. connector with a water feed or supply pipe 23 leading from any suitable source of supply of Water under pressure. The nipple 13 rcceives one end of a section of piping 24 connecting the annular passage 25 at the upper end of the valve casing with the lower end of a closed flush tank 26 which is suitably arranged above and in rear of the bowl. The partition 15 is provided with a valve seat 27 arranged in vertical alinement with the seat projection of the connector 16. A duplex valve 28 is disposed in the passage and is movable vertically between the valve seats 20 and 27. This valve is provided at its upper end with a valve member 29 which is winged or peripherally slotted for the flow of air and water about it and between said valve and the walls of the nipple 12, and said valve includes a renewable washer or seat disk 30, of rubber or other resilient or semi-resilient material, adapted to engage the seat projection 20 when said valve is in closed position and thereby cut off communication between the water supply pipe and the tank and the bowl. At its lower end the valve is provi'dedwith a valve member 31 of conical form to engage the valve seat 27 and control the port-14 for the flow of Water between the tank and the bowl.

The valve 28 is mounted upon the upper end of a rod or stem 32 which extends downwardly through the port 14 and the valve chamber and into the outlet extension 5 and is provided at its lower end with a guide flange or head 33 which is movable in the guide opening 6, whereby the lower end of the valve stem is accurately guided, the upper end of the stem and the valve 28 being guided by the wings of the valve member 28 within the nipple 12, whereby, in a simple manner, an accurate guiding of the valve and its stem in their motions is obtained.

Formed on or suitably applied to the stem 32 at a suitable point above the flange or head 33 is a-stationary collar or abutment flange 34, and surrounding the lower end of the stem between the shoulder 7 and this collar or flange 34 is a coiled expansion spring 35. This spring operates at all times when the valve stem is relieved from a predetermined downward forcing pressure to hold the seat in the normal or slightly elevated position shown in Figure 1 and to hold the valve in the normal position shown in Figure 3, in which the valve member 29 is closed and the valve member 31 is open. Also mounted on the stem or rod 32 above the collar or flange 34 is a sliding sleeve 36 having a flange 37 at its upper end, betweeuwhich flange 3i and the flange 34 is a coiled expansion spring 38. This spring 88 is shorter and stiffer than the spring and serves to normally hold the sleeve 36 elevated a predetermined dis tance above the flange or collar 34, as shown inFigure 3.

The body of the valve casing is provided with a forwardly extendin seat supporting bracket 39 Which is hollowed to form a chambered ofi'set receiving a valve actuating rocl-zer arm 40 having a forked or bifurcated free end 41 to straddle the stem 32 and engage'thc flange 37 of the sleeve 36, the opposite end of said arm being formed to providea gear segment 42 which is suitably fixed upon a motion transmitting rock shaft 43 journaled in the side walls of the chambered bracket 39. This gear segment 42 meshes with a gear 44 on the angular or non-circula r central portion 45 of a valve actuating rock shaft 6, which is journaled. in the side walls of the chambered bracket 39 and has its ends extending outwardly through stufling boxes which outwardly extending endsol the shaft fit in transverse openings inthe free ends of the fork arms 48 of a bifurcated or forked seat carrying bracket 48 and are suitably secured thereto,as by screws 48". The bracket 48 is suitably fastened to the closet seat 49, which is thus mounted for vertical swingini movements toward and from the bowl vi h the shaft 46, the latter being thereby rocked to communicate motion through the gear elements 44 and'42 to the valve stem 2:32. The stufling boxes 47 are provided with sitaitable packing 47 a and glands or followers 43'" fur an obvious purpose. I

As above-described, Figure 3 raised position of the valve, which its norshows the I is required, which is obtained by the variations of motion allowed by linear variations of the stiff spring 38. Anautomatic adjustment of the valve itself is thus provided for, to effect a positive water feed cut off action at cut off periods as long as the valve 31 is in serviceable condition, thus avoiding the necessity of frequent replacements of valve 31 or manual compensating adjustments from time to time, in order to secure a positive cut off action and to prevent leakage, which would otherwise be required. The parts 36 and 38 further provide a shock absorbing or cushioning connection between the valve actuating means and the valve to prevent any possibility of injury to the valve mechanism from shocks or jars occasioned, for example, by the accidental dropping of the seat 49 from its maximum raised position shown in Figure 3 to its service position shown in Figure 1, as will be readily understood.

In Figure 7 we have shown a different mode from that previously described of connecting the seat supporting bracket with the valve actuating rock shaft. As shown in Figure 7, the seat supporting bracket 48 haseach of its fork arms formed to provide a U-shaped yoke 48", the yokes of the crank arms being adapted to he slipped from above down upon the ends of the valve actuating shaft each yoke and the portion of the shaft which it engages being apertured for the passage of a fastening screw 48, theconstruction being such asto adapt these parts to be readily and conveniently connected and disconnected. V

In Figure 8 we have shown still another mode of connecting the seat supporting bracket 48 with the valve actuating shaftin which each arm 48 of the bracket is transversely slotted, one end of the slotted portion forming a journal receiving a sleeve upon an adjusting arm 48', which is fastened to the valve actuating shaft 45 by a pin or other suitable fastening member 48 The arm 48 has a threaded opening receiving an adjusting screw 48 hearing on the bottom wall of the slot and the head of which is accessible from the outer side of the slot to permit adjustment of said screw, whereby the seat supporting bracket may be tiltably adjusted with relation to the shaft 45* to vary the normal working positionof the seat with regard to the bowl within certain degrees. The top wall of the slot in the arm is provided with a threaded opening to receive a set screw or lock screw 48 which may be adjusted to bind against the head of the screw to hold it from upward movement and from retrograde rotation. By means of this adjustable fastening connection the position of the seat may also be varied to regulate its degree of downward operative movement and consequently the operative movement of lever 40 to compensate for variations in the, degrees of movementof the valve to effect a sealing engagement between the valve 31 and its seat 14, which construction may be used in addition to or in lieu of the motion compensating means 34, 36, 37 and 38, if desired.

In Figures 9 and 10 we have shown a moditied construction which dispenses with the use of parts 42, 43 and 44, and in which the transverse shaft 46 is mounted upon the valvecasing in rear of the valve stem and the crank arm 40 pro'ects forwardly for engagement with the dam e 37 of sleeve 36. This requires the use 0 a seat supporting bracket with fork arms of some considerable length to reach the required distance and to clear the casing to permit the seat to be swung upwardly to a vertical position; Also if these fork arms were made continuous, an objectionable backward movement of the crank .arm 40 would be required on such movement of the seat, and in makingthe bracketand long arms in a single casting the arms might be objectionably weak. These objections are overcome by l dividing the arms into sections or providing the bracket 48 with short arms 50pivotall coupled b a bolt 51 with arms 52 fastene to the sha t 46, on the angular part of which, in this instance, the crank arm 40 is directly mounted. The arms are formed with hinge knuckles for the bolt which are located adjacent to the upper edges of the arms, which are provided below the hinge knuckles with shoulders or abutment surfaces 53 adapted to abut when the arms are in longitudinal alinement. The bolt 51 is movable in slotted guides 54 at the front of the valve casing, whereby upward movement of the bolt and. arms .50 is limited. When the parts are in normal working position-the shoulders 53 abut, thus making the arms ri id for valve actuating motion under depression of the seat. The seat may, however, be swung upward to a substantially vertical position on the bolt 51 as an axis,.carrying with it the bolt up the limit of the upper ends of the slots in the guides 54, thus moving arms 52 upward and rocking shaft 45 sufficiently to swing arm 40 to a retracted position out of the path of the valve, as will be readily understood. This construction provides a working connection of considerable strength between the seat bracket and rock shaft. which dispenses with the use of gearing, and one which allows upward move ment of the seat to afull vertical position without an undue backward movement of the crank arm 40.

It will be seen from the foregoing de scription that our invention provides a flush valve mechanism which may be mounted vertically directly upon the upper rear portion of the bowl, and which may be connected in a simple and convenient manner with a water supply pipe and flush tank for working acmolten,

tions, and it willialso be. seen thatafvery simple typeot valve mechanism, devoid of cages or complex parts, is provided, whereby the use of parts requiring frequent adjust;

ments', repairs or renewals isdispensed with.

By" simply raising the seat so as to swing the crank arm out of the path of the collar 37'and uncoupling and detaching the con? nectoror union 16, full and complete access to the valve casin maybe obtained for the removal of the valve elements as a unit, for: cleaning, repa rs or replacements of'gasket 30 or other parts whenever lBCllllIECllIlSBIV:

ice. The yielding motion transmitting and compensating connection formed by the parts 84,86, 37 and38' ensures an easy transmission} offmotion to the valve stem, with entire elimination or materiahreduction of" shocks or jars, so that damage to these working parts, eve nlwhen the seat is roughtly handled, will be prevented, while the compensat-f ing action ensures a positive Working oonnection at all times-between the actuating crank arm and the valve whilepermitting automatic adjustment of the valve for a. positive closing movement of valve member 31' as long assaid valve member is in condition for use. As'the valve device iny'themainf 'consistsofparts not liable to beeasily injured or quickly worn, the gasket/'30 being the only part 'subj'ectto material wearan'd; required to' be renewed at intervals, it is evident that a valve mechanismcapable of long service; without repairs, renewals or adj ustmerits is-provided by theconstru'ction' employed.
