This invention isdirected to an improve.- ment 1n flushlng apparatus such asemployed 1n flush tanks for example, and'has for one of its objects the provision of avalve mechanism 1 which 1s an lmprovement on the valve mecha nism constituting the subject matter of my co-pending application Serial No. 231,819, filed November 8,1927, which has matured into a Patent No. 1,753,997, dated April 8,
101930. I v In that application I disclose a valve mechanism for flushing apparatus in which I pro- 'vide a hollow metal'valve, the sides of which are tapered or inclined providing a frustoconical formation with the base of the cone facing away from the seat for the valve. Thev valve seat is tapered, inclined or pitchedat a different angle from that of the conical sides of the valve, so that a line contact is provided with thevalve seat.
The present invention is an improvement 7 on thls construction in that means have been provided for checking the seating movement of the valve, thereby eliminating all noise of the valve striking its seat and producing a quietly operating apparatus.
In the drawings which show an embodiment of my invention:
Fig. 1 is a sectional elevational view; while Fig. 2 is a section on the line 2-2 of Fig; 1. Referring to the drawings in detail, 1 designates a pipe through whichthe water from the flush tank is to escape,the upper part of this pipebeing flared as indicated at, 2 to provide an inclined, pitched ortapered valve seat circular in plan.
The pipe 1 a short distancebelow the valve U seat is provided with two transverselyextending spiders 3 and 4:,the spider 3 being 7 0 provided with an aperture 5 while the spider 4 supports a cup-shaped or cylindrical retardingmember 6. f Y I The valve of the apparatus is designated 7 and is of metal and of hollow construction,
the lower portion of the sides thereof'being v tapered or inclined as indicated at 8 to pro- 1929.- serial No. 354,809.
*tom9 meets theapexof the frusto-cone 8 31 6 i I vides an edge 10 which seats on the valve seat 2 to provide a line contact. The top ofethe valve is provided with the usual liftrod 11. To the lower end of the valve I attach a rod or a tube12, If a tube the same willbe'closed at its lower end. This member functions as a guiding and retarding member and extends into the retarding cup 6. e The cup 6 is slightf ly tapered inside as indicated at 13, while the tube or therod 12 is straight sided. In opera- 7 tion it will be "seen'that the downward mo ve' menttowar its seat of he valve 7 willbere- 7 ,1 a I tardedby the water contained within the re- 7 1 tarding cup 6 which must be displaced by the guiding and retarding rodortube 12, thereby insuring a gentle seating of the valve and metal valve strikeliminating noise dueto the ing the metal seat. 7 r I WhatIclaimis: J
In flushing apparatus the combinationof a flush discharge pipe, a valve controlling the] discharge through said pipe, a seat for said 1 valve, a spider extending transversely of said discharge pipe and located below said seat, a liquid contai'ning'cup or cylinder sup 1 ported by said spider, said cuporcylinder; v
I closed at its lower end and havinga tapered bore and a'straight sided member carried by the valve and movable therewith andadapted I to enter said cupto displace liquidtherein thereby to retard the closing movement of the valve on its seat. 7 This specification April, 1929. 1
