VALVE FOR PERCOLA'TORS AND OTHER APPARATUS.
Specificationof Letters Patent.
. Patented July 6, 1915.
Application filed March 26-, 1913. Serial No. 757,024.
To all whom it may concern Be it known that I, Lours WOJIDKOW, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Valves for Percolators and other Apparatus, of which the following is a full, clear, and exact descrip .tion.
The invention relates to a valve, designed primarily for the percolator tube of a percolator coffee pot, and operating automatically to insure the circulation of the fluid through the tube, although the valve as such is capable of use in shower heads and other articles where an automatically acting valve may be useful.
The invention consists of a valve casing preferably in two parts, the inner part affor-ding means for applying the valve, and the outer part carrying the ported element, the valve itself, in the form of a shell or cup, being supported between these two members in such way as to open and close the ports under variation of pressure, as I will proceed now to explain and finally claim.
In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is an elevation, partly broken out, of sufhcient of a preferred form of percolator tube to illustrate the invention. Fig. 2 is a longitudinal section, on a larger scale, of a portion of such percolator tube. Fig. 3 is an end view of the valve. Fig. 1 is an elevation of a common form of shower head with the valve of this invention applied and serving as a venting device.
1 is a percolator tube and 2 is a plug adapted to fit in a Well in the bottom of a coffee pot in such way as to leave but a film of water at the bottom of the well and between such bottom and the bottom of the plug and exposed to the direct heat of the 1,095,973, dated May 5, 1914:. A number of valves for use in this connection have been devised, most of which operate by gravity; but my experience is that a valve acting by differences in pressure gives better result than one acting by gravity. a
The valve itself comprises an inner memher 4, having an outer screwthreaded portion 5, and a tubular portion 6, the outer end of which is provided with a centrally perforated spider or cross-piece 7; and an outer member 8 having a screwthreaded portion 9 by which this outer member is screwed into the inner member 4:. This outer member 8 is made with a valve seat 10 havingthe central port 11 crossed by a centrally perforated spider or bar 12. The outer member preferably is provided with a flaring mouth 13.
The valve 14: is a cup-shaped or shell-like structure, of metal, preferably having a central stem 15 projecting at front and rear so as to engage the holes inthe spiders 12 and '2'- to support the valve and to permit it to respond freely to variations in pressure. As shown this valve cannot close the tubular portion 6 and hence that part is always open for the passage of the fluid, but said valve operates to alternately cover and un cover the valve seat 10 for the circulation of the fluid through the device. In order to insure the non-closing of the part 6, the valve 14 may be provided with any suitable distance piece 15*, such as a drop of solder used to unite the shell and its stem, or a depression in the shell surrounding the stem.
The valve, as a whole, may be connected to the tube 1 in any suitable manner, as by frictionally engaging a lateral 16 on the tube.
By the construction described, the valve itself may be readily detached and disconnected and its parts thus made accessible for cleaning and repair.
The pressure exerted by the conversion of the water into steam will tend to close the valve by driving the shell 14 against the valve seat 10 and closing the port 11 therein, and as soon as this pressure is expended by the expulsion of the superposed column of water from the tube, then the pressure of the externally surrounding water will open the valve and admit water into the tube to be subjected to the heat and converted into steam as before.
Thus the valve acts autois very sensitive. As applied to a shower I head, it frequently happens that in these heads when the water is turned ofi, it will not drain out perfectly, and in that case when the water pressure is removed, the valve will open and admit air into the head and so expel any water that may tend to accumulate in it. As shown in Fig. 4, 17 is a shower head of well-known construction, and 18 is a valve such as just described,-applied to the shower head and operating as a vent in the manner described.
' The inner and outer members of the valve and the shell may be economically made of sheet metal, and standardized for ready renewal of parts. The shell itself is of very light weight and very sensitive to variations in pressure, so that it responds freely to the pulsations of the intermittent expulsions of water through the percolator tube. V
-Va'ria ti0ns in the details of construction are permissible within the scope and spirit of the invention. I
What I claim is a 1.- A valve, comprising a movable valve member, an innermember provided with an interior tubular portion adapted to engage the article upon which the valve is used and to support it inoperative position and serving to'limit the, inward throw of the movable valve member, an outer member provided with a valve seat and ported for the inward passage of fluid, the movable valve member operating automatically under variations in pressure and cooperating with the said seat to permit and prevent the flow of fluid, and means on the inner and outer members to separably connect them.
2. A valve, comprising a movable cupshaped valve member, an inner member provided with an interior tubular portion adapted to engage the article upon which the valve is used and to support it in operative position and serving to limit the inward throw of the movable valve member, an outer member provided with a valve seat ported for the inward passage of fluid, the movable valve member operating automatically under variations in pressure and cooperating with said seat to open and close the valve, and screwthreaded portions on the inner and outer members to separably connect them.
In testimony whereof I have hereunto set my hand this 24th day of March, A. D.
