VALVE.
Specification of Letters Patent.
Patented June 4, 1912.
Application ld'May 22, 1911. Serial No. 628,710.
To all whom it 'may concern: Be it known that I, CHRISTOPHER F. LAUFER, a citizen of the United States, residing at Richmond, in the county of Contra Costa and State of California, have invented certain new and useful Improvements in Valves, of which the following is a specication.
This invention relates to valves and particularly to that form of valve used in connection with boilers and has for its purpose to regulate the flow of water into a boiler.
One of the objects of the invention is to provide a valve of a compact nature which will prevent leakage while in use.
Another object of the invention is to provide an effective and durable construction which is composed of a few number of parts and which can be manually operated.
In carrying out the objects of the invention generally stated above, it will, of course, be understood that the essential features thereof are susceptible to changes in detail and structural arrangements, one preferred and practical embodiment of the invention being shown in the accompanying drawings, wherein Figure 1 is a fragmentary central vertical sectional view, constructed in accordance with this invention. Fig. 2 is a top plan view thereof. Fig. 3 is a plan view of the inside of the upper sect-ion of the valve.
Referring to the accompanying drawings by reference numerals it will be seen that the invention comprises a casing which is composed of two separable sections, comprising a valve body 4 and a valve bonnet 5. The body 4 of the valve is reduced and ex-` ternally threaded and the bonnet is provided with an internally threaded sleeve 6 adapted to engage the threads of the body 4. The body 4 is provided with a chamber 7 having an outlet 8. In order to attach the valve body to a boiler a reduced portion 9 is provided which is adapted to be engaged by a wrench. Projecting from this portion is an externally threaded extension l0 which is screwed into the boiler.
A rotary disk valve 11 is seated on the valve body 4 and is provided with a circular opening 12 Which may be brought into direct alinement with the opening 8 of the valve body. The outer surface ofv the bonnet 5 is provided with a raised portion 13 through which a large opening 14 and a smaller opening 15 extend. The opening 14 is internally threaded and adapted to be engaged by a pipe 16 which is connected with a pump or injector not shown. The inner surface of the valve bonnet is provided with a recess 17 that forms a raised portion 18 around the openings 14 and 15 and also forms an annular flange 19 against which the valve 11 abuts.
The valve 11 is provided with a centrally located upwardly extending projection 2O which is provided with a polysided opening 21. The projection 20 is adapted to engage with the opening 15 and extends only partially therethrough so that it will be necessary Yto have a key for the purpose of rotating the valve. The valve is also provided with a pendent stem 22 having a transverse groove 23 for conveniently grinding the valve. A key of this nature is shown which comprises a handle 24 which has a laterally projecting portion 25 from which a polysided key 26 projects, the said key being adapted to engage the opening21 of the valve 11. A pairV of vstops 27`and 28 are formed on the upper surface of the valve bonnet 5 to limit the movement of the handle 24 when the same is rotated.
It will be seen from the foregoing description that when it is desired to admit water to theboiler the key 26 is inserted into the opening 21 and then turned until the opening 12 of the valve comes in alinement with the opening 24 of the valve bonnet and the flow of water canbe regulated by only kpartially bringing the two openings in alinement. f i l It also will be obvious from the foregoing description that the device can be very readily taken apart in order that the same may be cleaned or'to permit of the grinding of the valve disk.
Having thus described my invention, what I claim is A valve comprising a hollow body portion having a reduced threaded portion, an extension leading from said body portion and provided with an opening communicating with the hollow central portion of said body portion, a valve resting upon said body portion and provided with an opening to one side of its center, oppositely disposed stems. leading from the center ofv said valve, one being provided with a groove in its end and the other with a socket, a bonnet resting upon said val've, the side walls of said bonnet into said last-mentioned opening' and into being threaded to engage the threads of said said socket to turn said valve. 10
lbody portion, said bonnet being provided In testimony whereof I affix my signature I with an opening formed in alinement with in presence of two witnesses.
