Specification of Letters Patent.

Patented May 1, 1906.-

Application filed June 26,1903- l 1 To all whom it may concern-.-

Be it known that 1, CHARLES V. RoBERTs, a citizen of theUnited States, and a resident of the city of Philadelphia, State of Pennsyl Vania, have invented certain new and useful Improvements in Valves, of which the followconnected to said valve to be established in a certain predetermined order and sequence, so as to cause the liquid which is controlled by said valve to flow in certain predetermined directions as required.

The valve which is the subject of my invention is particularly designed to be used in connection with water-filters which are adapted for use in dwelling-houses and other buildings and which require to be cleaned at certain intervals, depending upon the condition of water and the extent of use of the filter. Any form of filter may be used with said valve, provided said filter is adapted to'be cleaned by reversing the flow of the water therethrou h; but this form of valveis particularly a aptedto be used with filters of a construction such as is described and claimed by me in a separate application for Letters Patent, Serial No. 163,155, filed June 26, 1903.

In the filter last referred to the different requirements of the flow of water are as follows: First, the water passes from the supply-pipe through the filter downwardly and This is termed filtering to house and is the nor,- mal condition required to be produced by the valve. Second, the water passes from the supply-pipe upwardly throu h the filter and then to the waste-pipe. T 's condition of the valve is for the purpose of cleanin the filter and is termed cleaning. Thir ,the water passes from the supply-pipe downwardly through thefilter and then to the waste-pipe, and this condition of the valve is for the purpose of settling the filter and washing away the loosened sediment before the Water again enters the house-mains and is termed filtering to waste, Fourth, the wa ter passes from the supply-pipe through the valve to the house-mains without entering the filter, and this condition of the valve is termed by-pass. Fifth, the water-supply is entirely shut off within the valve and all flow stopped, which is termed valve closed.

For a full, clear, and exact description of my invention for producing these results ref erence may be had to the following specification and to the accompanying drawings, forming a part thereof, in which Figure 1 is a plan view of my improved valve, Fig. 2, an end elevation thereof; Fig. 3, a-view in elevation of the opposite end to that shown in Fig. 2; Fi 4, a perspective showing my improved va ve connected to a filter; Fig: 5, a perspective view of the cone or rotary part of the valve; and Figs. 6 to 15 inclusive, are pairs of sectional views taken alternately upon the lines X X and Y Y of Fig. 1, so that each of said views overlapand show the central portion of the valve between the diiferent ports. The different points at which the valve may be placed are clearlyindicated in Figs. 1 and 2 of the drawin s.,

Referring to the drawings, the numeral 1 indicates the port which is connected with the supply-pipe from the street-mains.

2 indicates the port to which is connected the pipe which carries the water to the house main. 3 indicates the port which is connected with the pipe carrying the water to the upper end of the filter.

4 indicates the port which is connected with the pipe passing to the lower end of the 5 indicates the port to which is connected the waste-pipe. These connections are clearly indicated in Fig. 1, in which the filter is indicated by the numeral 6.

The port 1 is provided with an opening 7 within the valve-casing, which communicates directly with the interior thereof, and the port 2-is provided with a similar opening 8 located, however, slightly below the horizontal diameter of the valve. The port 3 is provided with an opening 9, which communicates with the interior of said casing. The port 4 is diametrically opposite to the port 3 and also has an opening 10, which communicates directly with the interior of the casing.

The port 5, which is located at-the lower rear portion of the valve-casing, has a passage ,12, which extends horizontally beneath the valve-casing for a short distance and then ICC curves laterally and then forwardly until a point is reached which is substantially in the same transversed plane with the ports 3 and 4, where said passage then communicates with the interior of the casing, as indicated at 13.

The valve-cone 14, which is best illustrated in Fig. 5 and also shown in section in each pair of the transverse sectional views, is provided with two sets of chambers in the forward and rear portions thereof, which have openings communicating with the exterior of said cone and some of which also communicate with each other.

15 indicates a partial transverse partition between the two sets of chambers, while 16 indicates a longitudinal partition in the forward chamber, and 17 indicates a pair of connected partitions'which form a passage 30 from the forward chamber 18 to the rear of the cone and is adapted to communicate with either of the openings 7 and 8. The chamber 19 extends the whole length of the cone and has openings 20 and 21 adjacent its forward ends, which are adapted to communicate, respectively, with the openings 9, 10, and 13, which lead to the ports 3, 4, and 5, respectively. The chamber 19 also has an opening 22, which communicates with either of the openings 7 and 8 separately and also is large enough to include both of said openings 7 and 8, as indicated in Fig. 12. The central transverse partition 15, above referred to, and the end plates of the cone are represented in Figs. 6 to 15, inclusive, by light and heavy shading, respectively.

The forward or larger part of the valvecone is provided with a stem or projection 23, which terminates in an angular portion 24 to receive a wrench, handle, or other means for rotating the cone. Said stem 23 is also provided with an indicator hand or arm 25, which is attached thereto in any suitable manner.-

The exterior of the valve-casing is provided with lugs at diametrically opposite points near the larger end, to which are attached arms 27, which carry the semicircular segment 28. To this segment28 is attached the indicating-band 29, which cooperates with the arm 25 to show the different positions of the valve-cone 14. The first position of the valve (shown in Figs. 6 and 7) is that which allows the water to pass from the supply through the filter in a normal direc tion and thento the house-mains, or, in other words, the valve is in the filtering to house position. When the valve is in. this position, the water passes through the following openings or passages, 1, 7, 22, 19, 9, and 3, to the upper portion'of the filter and from the lower portion of the filter through 1, 10, 30, 8, and 2 to the house-mains. In the second position of the valve (shown in Figs. 8 and 9)the cleaning position-the water passes from the supply-pipe through 1, 7, 22, 19, 10, and 4 to the lower part of the filter and from the upper part of the filter through 3, 9, 19, 30, 13, 12, and 5 to the Waste-pipe. In the third position, or filtering to waste, Figs. 10 and 11, the water passes through 1, 7, 22, 19, 9, 3 to the upper part of the filter and from the lower part of the filter through 4, 10, 18, 13, 12, and 5 to the waste-pipe. In the fourth position, or by-pass, Figs. 12 and 13, the water passes from the supplypipe through 1, 7, 22, 8, and 2 directly to the house-main, communication to and from the filter being entirely out off, as indicated at 9 and 10 in Fig. 13. In the fifth or valve closed position the water is prevented from entering the port 1 and the openin 7 by the exterior of the cone, which is in icated in Fig. 14,- but the other elements of the valve when the cone is in this position allow the water to pass from the housemains through the waste-pipe by establishing communication among the passages in the following sequence: from the house-mains to 8, 22, 19, 13, 12, and 5 to the wastepipe. This position of the valve allows all the water in the house-mains to be drained 01f directly to the sewer.

It will be noted that in the usual use of my valve only three positions are employed, the indicator being immediately returned to the filtering to house position from the filtering to waste position. The by-pass position is intended for use only when the filter is being repaired, a new one substituted, or the filtering material changed, and the valve closed position is only used when the entire Water-supply system is put out of operation. It will also be noted from a comparison of Figs. 8 and 9 of the drawings with Figs. 10 and 11 that in changing from the v cleaning to the filtering to waste position the inletport from the watersupply is never closed and also that the outlet-port 4 is not closed during the change. This is an advantage from the fact that no strain is put upon the supply-pipe entering at 1 and also that no 7 strain is put upon the filter by having the lower outlet-pipe closed, for if such were the case the water flowing through the pipes and intothe filter with considerable pressure and velocity would act as a waterhammer and would put a great strain upon said parts and possibly cause them to leak or burst. This is true also during the change from the filtering position to the by-pass position,

as will be seen by comparing Figs. 6 and 7 .with

12 and 13, since as the opening 8 is closed by the end of the partition 17 on one side thereof, or that side which connects with the passage 30, the opening on the other side of the partition, or that which connects with the opening 22, is opened. It will thus be seen that the water is not suddenly shut off in going from one to another of the positions mentioned and is only shut off when the valve is placed in the closed position. I do not wish to be limited to the exact details of construction of the valve embodying my invention herein set forth, for changes may be made in the form, proportion, and arrangement of parts without departing from the 1 spirit and scope thereof.
