Combined Manually and Automatically Actuated Valves, of whichthe following 1s a specification.
: sive to manufacture, reliab invention comprises the various novel This invention relates to a valve of that type which, under normal conditions, can be opened and closed by turning the valve stem, and under abnormal conditions can be automatically opened from a remote oint.
The invention has for one 0 its objects to improve and simplify the construction and opgration of devices of this character so as to comparatively simple and inexpene and efficient in use, and composed of comparatively few parts. K a
Another object of the invention'is the provision of an improved meansfor releasably holding the valve seated.
With theseob'ects in view and others, as w1ll.appear as t e description proceeds,fthe
eatures of construction and arrangement of parts which will be more fully described eremafter and set forth with particularityin'the claims appended hereto.
In the accompanying drawing, which illustrates one embodiment of the invention, Figure 1 is a vertical longitudinal section of the valve. Fig. 2- is a perspective view of the releasable valve stem engaging means and its operating device. Fig. 3 is a perspective view 'of the releasable valve stem engaging means detached.
Similar reference characters are employed to designatecorresponding parts-throughout the views. Referring to the drawing, 1 designates the body or base section of the valve casing, and 2, the upper section which is attached to the base section by means of an exterhal threaded boss 3 screwing into the internally threaded counterbored portion 4. Thesec-v tion 1 has a chamber 5 from which extends a lateral passage 6 there being a spherical. boss 7 formed on he casing at the end of the outlet for connection with a pipe. epending from the section 1 is a nipp e8 also or connection with a pipe or equivalent devlce,

and this nipple has a central passage 9. a
which communicates with the chamber 5.
bore 10 disp axiall in alinement with the chamber5 for rece ving the valve stem 11. The stem is formed at its lower end with a head 12'sha ed to engage the seat 13 at the inner end 0 the passage 9, the head The section 2 of the casing has a central being enlarged to form a follower or piston 14: that carries a peripheral acking ring 15 for snugly fitting the chain er 5 and preventing leakage upwardly through the bore 10 of the casing. A cap nut 16' is screwed into the upper end ofthe section 2 of the casing and' this nut is formed with a chamber 17 for acconmiodating a helical spring 18 arranged around that portion of the stem that passes through the cap nut. This spring has its lower end bearing against a collar or washer 19 seated in an internal shoulder .20 formed by counterboring; the section 2' of the casing, and the upper end of the spring bears a amst 'a nut 21 engaging the screw threade portion 22 of the valve stem. This nut' forms an a'd'ustable abut- .ment whereby the tension of t e s ring can be set to any desired point, and t e nut is held in place by a jam nut 23. The spring thus tends to move the valve stem in a direction for unseating the valve. On the upper end of the stem is a hand wheel 24 or equivalent device for facilitating the turning o the stem and this turning causes longitudienga ed by a spring-pressed follower 25 whic has its end face concave to correspond withthe radius of the threaded portion of the valve stem, and on this concave face 26 are. spiral ribs 27 to engage of the stem. leasabl'e stem-engaging means and forms a nut whereby the rotation of the stem will The section 2 of the casing has a lateral opening orichamber 28 communicatin with the bore 103?;for accommodatin the fo lower 25, and the: flip nut 29' closes the latter. opening and an abutment for the outer end of a Spring BO which holds the follower in engagement with the stem, the inner end of 'thefsprin'g bearing against shoulders or proi'xections 31 on the follower. The cap '29 as an opening 32 through which the foltower pro ec'ts and the ro ecting' end of the the thread 25' This follower constitutes a re-' follower is formed with a diametrical slot 33 for accommodating an operating lever 34 which is connected with the follower by a pivot 35. The outer face of the nut 29 has a diametrical slot 36 in which the lever engages, and the heel portion 38 of the lever rides in the bottom of the slot and forms a sliding fulcrum. The outer end of the lever may be connected with any suitable device such as a pull cord 39, whereby the lever can bev operated from a remote point.
When the parts are in the position shown in Fig. 1, the valve is locked in closed position, and though the spring 18 is under tension, it cannot open the valve because of the engagement between the inwardly springpressed follower 25 with; the valve stem. The valve can be opened, however, by turning the hand wheel 24. In case it is desired to open the valve from a remote point, it is merely necessary to pull on the cord 39 to tilt the lever to the dotted line position, whereby the follower is retracted for disengaging the teeth 27 from the screw thread 25'. The spring 18 is thus allowed to act for automatically opening the valve. As soon as the pull on the cord 39 is released, the follower 25 will move inwardly for engagement with the valve stem so that the valve can be again closed by turning the hand wheel 25.
From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, to ether with the device which I now consi er to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative," and that such changes may be made when desired as are within the scope of the claims appended hereto.
Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is
1. The combination of a casing a rotary and longitudinal movable valve stem, 11 valve carried thereby, a seat in the casin asprmjg arranged to move the stem longitudinal y, a thread on the stem, a springwhile the element engages the said thread,
and means for releasing the element from the thread to permit the spring to move the valve stem. i
3. The combination of a casing, a seat therein, a valve arranged to engage the seat, a stem, a thread on the stem, a s ring arranged on the stem to move the va ve open, means for manually turning the stem, a spring-pressed follower spiral ribs on the follower for meshing w1th the thread of the stem, a spring pressing on the follower for holding it in engagement with the stem, and means for releasing the follower to permit the first-mentioned spring to open the valve.
4. The combination of a casing, 'a seat therein, a valve arranged to engage the seat, a stem for the valve, a thread on the stem, a sprin r surrounding the stem at a point outward y from the thread, an adjustable abutment on the stem on which one end of the sprin bears, afixed abutment in the casing for t e other end of the spring, a member extending at right angles to the stem-- and havin 'spiral teeth or ribs engaging the threa of the stem whereby the valve can be openedand closed by the rotation of the stem, a spring pressing on the member for holding it in engagement with the stem, and a device for releasing the member from the stem against the tension of the last-mentioned spring to permit the first-mentioned spring to open the valve.
In testimony whereof I aflix my signature in presence of two witnesses.
