IMPROVEMENT IN SELF-CLOSING VALVES.

Specication forming part of Letters Patent No. [82.014, dated September 12, 1876; application filed April 29, 1876.

To all whom it may concern:

Be it known that I, FERDINAND BEER, of Frankfort-on-the-Main, Germany, have invented certain new and useful Improvements in Self-Closing Valves, of which the following is a specification:

My invention relates to a device whereby a valve is made to be self-closin g when the power used in opening it has been removed, and is constructed so as to obviate the hydraulic shocks resulting from the varying pressure of the feed-Water.

My invention consists of a peculiar construction and combination of parts, which will be 'fully hereinafter described and specifically pointed out in the claims, a preliminary description being therefore deemed unnecessary.

In the accompanying drawings, Figure l is a partial sectional elevation of a valve of my invention, representing the air-,chamber and diaphragm in section, while the valve proper is in the elevation. Fig. 2 is a plan vieu7 of the same. Fig. 3 is a sectional elevation of the valve proper, drawn to an enlarged scale.

In the annexed drawings, Arepresents a reservoir, which serves the purpose of equalizing the uneven pressure resulting from the feeding process or from the opening or closing of the valve, and greatly increases the durability ofthe pipes and valves, while the diaphragm a, having a small opening, regulates the speed of the water-supply, thereby securing a quick, even flow of water through the valve, and a more ready closing of the same, inasmuch as the Water reaches the wide opening to the valve after passing through a small opening regulating-pistons l and m,- the regulating valve-rod f, with valve at s; the counter-cur- `rent channels n n n n', with valve atp,- the escape-opening g, for escape-pipe r; the aperture b, for the escape of air.

The regulating valve-rod f enters the valvecasin g B through the stuffing-box e, which is secured to the upper part of the lid B' by means of a screw-coupling. The staple t, fc

vthe reception of the lever g h t', is secured t the valve-rod f by means of a screw-coupling c', in such a manner as to permit the said roi to revolve in the said screw-coupling for th purpose of regulating the speed of the valv K and Kl and pistons l and m. Inside th casing B B the valve-rodfsupports the valve K K and pistons Z and m. The chamber is connected with the chamber O by mean of the channels u nn and valve s, and agai the chamber Ois connected with the pressure supply u by means of the valvep and chan nel n. The chamber al communicates Wit] the elevator-pipe r and With the escape-pip c. rIhe stop-screw c regulates the escape The closing of the aperture of supply at u i attained by means of pistons of unequal di ameters at l and m. The piston at Z havin; the greater diameter, and, consequently, th greater pressure-surface,,forces the valve K to its scat at a. The speed of the said valvi can be regulated, and the hydraulic shock ob viated, by screwing together in a greater o: less degree of the valve-surface at s, Whicl occurs when the valve-rod f is screwed int( the piston l at f to a greater or less exten' by means of a rod inserted into the hole at w In this manner the opening cross-cut at s which communicates with the counter chan nels n n n n", may be narrowed or Widener at pleasure, thereby securing a more or less rapid transfer of water from the chamber C to the chamber O.

A point of great importance in this con struction is the fact that by attaining a clos ing of the valve entirelyfree fromany jar, the durability of the whole apparatus is great ly increasedl rIhe screw-valve C is used foi cutting off the supply when repairs may be necessary.

The entire apparatus is secured to a platef P, by means of screws. All the brass parts in the interior of the apparatus may be nickelplated, thus obviating the formation of verdigris, and its deleterious effects on the health of the public, and increasing the durability oi the valve.

The mode of operation is briefly described as follows: When by means of any of the faniliar appliances the lever g h i, turning on a ixed axis at g, is lifted, the pistons Z and m md valves K KIl move in the same direction, Jeing connected with the lever g h vl by the valve-rod fand the valve K, and then the .eather packing abovethe disk K shuts off ahe escape-valve at u. The leather packing Beneath the disk K, and then the valve K, )pen the aperture at u, and the Water in the zhamber O enters through the channels s n YL n" into the chamber Q. The water inthe tir-reservoir A reaches the escape g in passing through u and w, and then through the elevating-pipe 1'.

When the upward draft ceases the difference of pressure between the large piston l and the small piston m has its effect. The water in chamber O forces itself through the channel n n' n and through the valves s into the chamberO, and here exerts its influence Dn thelargerpiston-surface. The channel n and valvep effect the equalization of pressure between the supply and the chambers O and O'. The piston K', in moving downward, shuts off the passage of water to the escape at u, and K opens the aperture to the drainpipe c' at u. The leather packing below K closes completely at u, and the elevator-pipe r' empties itself into the chamber u, and finally, through channel c', into the open air.

If it is desired to save the Water which here escapes after each draft, the least waste of water may be entirely prevented by the insertion of acylindrical vessel between the valve and elevator-pipe, as shown at D, and leading the Water here escaping into the elevatorpipe by means of an injector adjusted at the bottom of this cylindrical vessel. The Water accumulating in the vessel D after each draft is carried away With each succeeding draft, thus order cuts off the feed-water beforeopening the entrance to channel c', substantially as and for the purpose specified.

In testimony whereof I have hereunto set my hand this 18th day of March, 1876.
