" IMPROVEMENT IN vALvEs.
Specification forming pari of Letters Patent No. 155,667, dated October 6, 1874; application tiled september 19,1874.
OAsE A.
. the general line in which fluids pass through the valves. My improvement consists, in the combination with such a seat, of a hinged flap,
composed of an elastic material, and of braces or stiffeners, which, while they absolutely prevent the flexible flap from being drawn into the valve-port, do not prevent the seated portion of the ilap from being free to adapt -itseltl to the -valve-seat, and to close down upon and surround any ordinary extraneous matter liable to be temporarily deposited upon the valveseat, and thereby secure a practically valvetight joint therewith regardless of the presence of said matter, thus giving it especial value for use in pumps and apparatus for transferring iiuid and viscous matter from privy-vaults, cess-pools, 8vo., to transit-tanks; and I do hereby declare that the following specification, taken in connection with the drawings furnished and forming a part of the same, is a clear and accurate description thereof.
Referring to the drawings, Figure 1 represents one of my valves iu perspective. Fig. 2 represents the lower side of thevalveflap.
Adenotes. the valve-seat. Its surface-line is inclined at an angle of,V about forty-live degrees from the axial line of the valve-port, so' that the flap, in being moved about the same number of degrees, will wholly uncover the valve-port and allow a free and unobstructed discharge to its fullest capacity. B denotes theiap. It is secured to the lower. side of the valve-seat, and is preferably composed of thin elastic vulcanized sheet rubber. At the point of attachment to the seat it is advisable to employ a flat bar or strip of metal, as at c,
with more or less flexible faces, or with covers wholly elastic. The rigid cover with flexible face serves a good purpose in operating withV water, or with ordinary duid matter. So, also, does the wholly flexible valve-cover perform good service when operated under light pressure. Both are, however, objectionable for use in operating upon the contents of vaults and cess-pools, as the former cannot practically operate if any extraneous matter be temporarily deposited upon the valve-seat; and the latter, in operating with viscous matter of considerable weight, and under the necessary pressure, are liable to retreat into the valveport and become inoperative. In my improved valve, the flap is free to adapt itself to its seat, and also to any matter temporarily deposited thereon; and at the same time itis practically impossible for it to be forced backward into the valve-port. These desirable features are effected by securing to the flap a series of braces of peculiarform and arrangement. 0n the under side of the flap, the
braces b are secured to the surface or embedded in the rubber. They are preferably composed of flat stiff strips of sheet metal, and
are set radially, as shown, and have a length in each instance nearly equal to the length of the opening on the inclined line of the valveseat. On the upper side of the flap are a series of braces, o, also set radially in lines corresponding with those of the braces b. In the drawings, ve braces, c, are shown, and but three of the braces b. Three of the braces c are coincident with the three lower braces b,- and they are respectively united thereto by rivets, which pass through the braces closely adjacent to their ends. The braces c, however, are of considerably greater length, and extend at each end beyond the point of riveting, so as to slightly overlie the seat. It will be seen that the braces occupy lines corresponding with the lines of discharge through the valve, and that the flap is wholly flexible laterally, but practically rigid longitudinally. For this reason, it is practically impossiblefor it to be forced into the valve-port, and at the same time it is free to close down upon any extraneous matter liable to lbe temporarily lodged upon the seat. Should a small stick, for instance, bein the act of passing through the valve at its closure, it Would be moving in the line of discharge parallel with the stiffeners; and it will be readily obvious that the latter would, in no manner, prevent the seated portion of the valve from closing around the stick and forming proper valve contact with the flap which extends beyond the ends of the braces may be made very thin and extremely eXible, and the valve-seat should be of sufficient width or area to afford an extensive contact of the flap therewith.
I am aware that it is not nen7 to employ braces or stii'eners with flap-valves, as they are shown and claimed in my Letters Patent No. 141,587, dated August 5, 1873.
Having thus described my invention, I claim as new, to be secured by these Letters Patent- The combination, with an inclined valve-seat, of a flexible flap-valve, provided with radial stifieners or braces, substantially as described.
