`SPECIlICAEiSION forming part of- Letters Patent No. 286,656, dated Cetober 16, 1883.
Application filed December 27, 1.852. (Xo model.)4
Totali whom, t iii/ ay concern,.- l f Be it known thatV I, PirrnnfGAnnnrr VANl ViE, of Cleveland, in the county of Cuyahoga and State of Ghio, have invented certain new i and useful Improvements in Straight-Yay Valves; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it pertains to -make and use the same.
My invention relates to improvements in stop-valves, and more especially to that class of valves known as straight-way valves, 7 7 commonly used for water pipes and mains; and it consists of certainfeatures of construction and combination of parts7 hereinafter described, and pointed out in the claims. In the use of this kind oi' valve much difficulty is encountered by sediment-usually sand and mud settling in the bottom of the central chamber of the valve in such a manner as to obstruct the working of the valve, and also by the sand getting between the sea-t and the valve, therelt is for the purpose of preventing the accumulation of sediment, as aforesaid, that I lhave invented this new device.
One embodimenty of my new device is intended also as an improvement on' a former invention for which I applied for Letters Patent andthe claims were allowed December 5, 1882, Serial No. 70,857, and Vto which reference is In the drawings, Figure ll is a vertical sectional view lof a valve in which is embodied my invention. Figs. 2, 3, and 4 are enlarged detailed. drawings illustrating parts of Fig. 1.
manner oi' constructing a portion of my new device. l
A represents the body or casing of the valve 5 B, the valve-head; C Crthe main passage-wayl through the valve, and F the centra-l chamber of the valve. Y
E is the valve-seat on the inlet side ofthe valve, and E is the valve-seat on the outlet side ofthe valve.
D is a passage-wifey under the main opening in the seat E and leading from the `chamber F into the passage C beyond the said valve-'seat E". 4
In 2 is shown the valve-seat E', and also the opening of the passage-way D.
The valve-head B is provided with the selfadjusting planoconvex disks b and b', the former on the inlet side of the valve and the latter on the outlet side of the valve. The disk b, as shown in the enlarged detailed drawing Fig. 4, is beveled on the flat side, thereby diminishing the surface that comes in contact with the seat E, but leaving still a suffi-v cient surface to cover the opening in the said It will be seen that by beveling or diminish ing theface of the disk b the said disk will not extend downward as far as Lthe disk b', and
hence in closing the valve the opening in theA the passageway D, removing all sediment from the chamber ofthe valve, after which, by forcing down the head B still farther, the disk b will close the opening in the seat F, and thus entirely close the valve. In opening the valve the inlet side udll be ii rst opened, again cans ing a strong current to flow through the passage-way l), as Ibefore described.
The disk b', asshown in Fig. 3, may beprovided with a lip, be, extending downward far enough to close the passageway D at the same time that the disk b closes the opening in the seat E; also, when the valve is open the lip .If will extend down far enough to cover a small portion of the opening in the seat E', thereby causing a/strong current to iiow through the passage-way D. Then it is desired to use a lip, as aforesaid, a cheap and convenient way of making this point of the device is shownin Fig. 5, where the head B mayk be made solid, with a flat face on the outlet side and terminating in the lip b2. The other side of the head may be coneaved in a suitable manner Vto form a seat for the beveled planoconvcx disk b, as before described.
The disk b might be made with a face of the required size without lieveling the edges; but I prefer the beveled edges for the reason that they give such direction to the water as will IOO sage-way, as at D, will embody my invention.
What I claim is- 1. rIhe combination, with a valve-chamber having a passage-way, D, 'of a valve-head provided with a plano-convex disk on the inlet side thereof, and provided on .the outlet side with a-iiat surface for closing the outlet side of the valve, and terminating in a lip or projection of such shape and length as will close the passage-way D at or about the same time that the inlet side of the valve is closed, substantially as described.
l 2. The combination, with the valve-chamber provided with the passage-way D, of a valve-head provided on the inlet side of the valve-chamber with a disk having afiiat outer face and lower beveled edge, while the opposite side of the said valve-head on the outlet side is made with a flat surface and terminates in a depending lip or projection of such shape and length as will close the passage-way D at or about the same time that the inlet side of the valve is closed, substantially as set forth.
3. In a straight-way valve, the valve-chamber provided with the passage-way D, in combination with the plano-convex disk b, having a beveled edge on the flat side thereof to give suitable direction to the water, so as to more thoroughly cleanse the chamber of the valve, substantially as set forth. v
In testimony wh ereof I sign this speciiication, in the presence vof two witnesses, this 18th day of December, 1882.
