A. c. BRQWN FAUCET Filed June 9, 1934 facilitated.
Patented Mar. 26, I935 This invention relates to improvements in faucets and is here shown as applied to a selfclosing faucet. 4
Among the features of my invention is the provision of a dash pot cylinderthat is readily removable with the seatand. valve disc through the top of the casing. Adjustment of the cylinder, repair andreplacement are thus greatly Another feature of my invehtionis' an improved. dash pot with improved means for adjusting the rate of flow of water into and out the faucet can be adjusted to a fine degree.
My improved faucet is greatly simplified in construction and operation and designed to give maximum efficiency with a minimum cost of manufacture and maintenance.
Other features and advantages of my invention will appear more fully as I proceed with my specification.
In that form of device embodying the features of my invention shown in the accompanying drawing- Figure 1 is a vertical sectional view; Fig.2 is a view taken on the line 2 of Fig. 1; and Fig. 3 is a view taken on the line 3 of Fig. 2.
As shown in the drawing, 10 indicates a casing open at the top and provided with an inlet opening 11 at the bottom and an outlet opening 12 at one side. 13 indicates a sleeve in the casing with an inlet opening 14 at the lower end, said end engaging a portion of the casing surrounding the inlet 11 in the casing. The lower end of this sleeve 13 also carries a seat 15 (here shown as removable from the sleeve). The sleeve 13 is also provided with a plurality of outlet openings 16 discharging into the outlet 12 in the casing 10.
The top of the casing is closed by a cap 1'7. 18 indicates a vertically movable metallic stem extending through the sleeve. The lower end of this stem projects through the inlet opening 14 in the lower end of the sleeve 13 and carries a valve disc 19 adapted to seat upon the seat 15 to close the faucet when the vertically movable stem 18 reaches the upper limit. of its movement. Downward movement of the stem 18 is adapted to remove the disc 19 from the seat 15 to open the faucet.
The upper end of the stem 18 extends through a centrally arranged hole in the cap 17. 20 indicates suitable packing in the hole surrounding the stem. The upper' end of the stem 18 is threaded into an extension nipple 18 carrying a disc of heat insulating material 21. 22 indith'ereof never becomes uncomfortably hot.
PATENT -'0F C cates a metal cap carried by the disc 21 with its upper surface spaced therefrom, as indicated by 23. By this construction, heat conducted by the stem'18 or other parts of the faucet is largely insulated from the cap 22 so that the top surface 24 indicates a spiral spring surrounding the stem 18 between the disc 21 and-the packing 20. This spring servestohold the packing in place and also operates to yieldingly hold the faucet in closed position so as to make the same selfclosing. of the same, whereby the'speed 'ofoperation'of In connection with a self-closing faucet, a dash 'pot is especially desirable in order to retard the closing thereof. This is highly desirable in connection with faucets that close with the pressure or flow of water or other fluid. 25 indicates a dash pot cylinder removable through the upper end of the casing 10 after the cap 1'7, sleeve 13 and stem 18 have been removed. This cylinder is provided with an outwardly projecting flange 25 at its upper end adapted to be gripped between the lower end of the sleeve 13 and the portion of the casing 10 surrounding the inlet opening 11. Since the sleeve 13, as here shown, carries on its lower end a removable seat 15, it may be more accurate to state that the flange 25 on the cylinder 25 is gripped between a portion of the removable seat 15 and a portion of the casing 10 surrounding the inlet opening 11. Since the upper part of the seat 15, however, does not function as a seat, it may broadly be considered as a part of the lower end of the sleeve 13 or the equivalent thereof. In construction similar to this, the lower end of the sleeve 13 may have a seat formed integral therewith. In such case the flange 25 would be gripped between the lower end of the sleeve (such lower end being integral with the sleeve) and a portion of the casing surrounding the inlet opening 11. In describing and claiming the invention, therefore, it is proper to state in broad terms that the flange 25 is gripped between the lower end of the sleeve and a portion of the casing surrounding the inlet 11.
The lower end of the stem 18 is provided with a piston or cup washer 26 operating in the cylinder 25. Above this piston the cylinder 25 is provided with holes or inlet openings 25'" for the flow of water.
28 indicates a nut on the lower end of the stem 18 to hold the disc 19 and piston 26 thereon.
The lower end of the dash pot cylinder 25 is provided with a screw 30 extending through a port or bleed hole in the lower end thereof. This screw is provided with grooves 3O constituting water passages. The screw carries a washer 31 under its head and 32 indicates a member gripped between the washer 31 and the bottom of the dash pot 25. The member 32 is made of compressible porous material and may comprise, for example, a felt washer. In the closing movement of the faucet, the cup washer 26 moves upwardly in the cylinder 25. To permit this movement, there must be a fiowof water through the porous member or washer 32 to get to the grooves 30 to enter the cylinder 25 through the bleed hole. The rate of flow of water through the memberi32 will; therefore, govern the time rate of closing of the faucet. The rate of flow through the member 32 is adapted to be regulated by compressing the member 32 more or less by tightening or loosening the screw 30. I =havefound thatby thus varying the compression of the member, 32, I can regulate the speed of closing to a very fine degree. By tightening the screw sufiiciently, the
.member32 can be compressed to-such .a degree that the flow of water through it is very slow. This will make the closing of the faucet very slow.
While I have shown and described certain-embodiments of my invention, it is to be understood that it is capable of vmany modifications. Changes, therefore, in the construction and arrangement maybe made without departing from 1 the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly-as permissible, in view of the priorart.
What I .claim as new, and desire to secure by Letters Patent, is:
1. In a faucet comprising a casing and a removable sleeve having a valve seat at the lower end thereof and a discharge opening, a removable dash pot cylinder provided with a flange adapted to be gripped between the lower end of said sleeve and a portion of the casing, said cylinder having a bleed hole, and means for regulating the rate of flow of water through said bleed hole, said means including a compressible porous member and means for varying the compression OfzSlld member.
2. A casing with an inlet and an outlet; a sleeve in the casing with an inlet at one end, said end engaging a portion of the casing surrounding said inlet of the casing and carrying a seat, said sleeve also having an outlet discharging into the outlet in the casing, said sleeve being removable through the top of'the casing; a vertically movablestem extending through the sleeve with its lower end projecting through the inlet in the sleeve; tau-valve disc on the-stem adapted to rest -on.the:seat on flie :slee've; a dash pot cylinder in the casing below the inlet with a flange gripped between thelower-end'of the sleeve and a porand means for regulating the flow of water through said bleed hole, said means including a compressible porous member and means. for varying thecompressionof said member.
