VALVE.

Application filed March 27, 1915.

To aZZ whom it may concern:

Be it known that I, EDWARD E. OETTINGER, a citizen of the United States, residing at Chicago, county of Cookgand State of Illinois, have invented certain new and useful Improvements in Valves, of which the following is a specification.

This invention relates to valves.

My invention particularly relates to valves for steam, hot water and hot air radiators, although it is not limited to such use, and it has for its objects the elimination of packing, the provision of a steam-tight closure, improved means for operating the valve, a novel valve construction, whereby the valve is rendered self-packing, the provision of novel means whereby the valve may be operated by foot pressure and thus do away with the necessity of repeatedly turning the valve wheel or handle commonly employed on steam and radiator valves; further, to provide a novel self-latching look ing device for the operating means, and also to provide a cap, avalve-stem, and a spring arranged and adapted to co6perate in an improved manner, whereby the valve is selfopening and adapted to hold itself in an open position and may be closed, or partially so, by the pressure of the foot on the cap and against the action of the spring, the cap being locked by the self-latching device.

My improvements provide a packless, selfopening valve adapted for quick and easy opening or closing by foot manipulation and for the prevention of any leakage of steam.

I am aware that my invention is susceptible of many modifications, both in its valve structure, its operating means, latching means, and other features and parts. Some of those modifications are set forth fully hereinafter and are shown in the accompanying drawings; others will suggest thenr selves to those skilled in the art who may have my invention before them. I do not, therefore, limit myself to the details of con struction shown in those forms which I have illustratedand described, unless so specified in the claims.

The valve shell or, casing 1 is. provided with internal screw-threads at its top as shown at 2 for the connection of the fitting or shell 3 which carries the valve-operating devices. The fitting 3 has a concavity 4- extending to the bottom thereof and above this is a chamber 5. 'Rotatable in the concavity 4 and chamber 5 is the valve-turning device 6 which is shown in detail in Figs. 6 and 7. The lower portion thereof is of frusto-conical shape, as shown at 7 and fits snugly and rotatably in the concavity 4 and is provided with a socket 8 to receive the squared upper end 9 of the butterfly valve 10, whereby said valve turns with the memher 6. The member 6 has a flange 11 which bears upon the shoulder 12 of the fitting 3. Projecting upwardly from the member 6 is a stem 13 which has two or more inclined or spiral ribs or feathers 14 which are of such a pitchthat there will be imparted to the valve 10a turning movement of ninety degrees under the influence of the operating devices to effect full closing or full opening of said valve and permittingpositioning thereof at any intermediate point. Contained within the chamber 5 is a convolute spring 15 (Fig. 14) whose base rests upon the upper face of the valve-turning device 6 tion is circular or, rather, of annular form and provided with a concavity or well 17 which receives the stem 13 and is provided with a spiral or inclined channel or groove 18 into which the rib 1a fits so as to be adapted to permit relative sliding of the cap 16 and the stem 13. If two of the ribs 1d be used, there will be employed two of the grooves 18. The spring 15 bears against the lower face of the cap 16 and by its expansion tends to hold the operating device 6 snugly rotatable in its concavity 1 so as to prevent escape of steam and also obviating the necessity of employing packing, thus eliminating a troublesome and expensive feature of valves. The form of the device 6 and cavity a, in connection with the action of the spring 15, takes up all lost motion and wear. The spring retracts the cap upwardly, as shown in Fig. 1. The spring 15, by holding the valve turning device 6 snugly in concavity 4 insures a smooth, uniform wearing of the contacting surfaces of these parts and prevents'the escape of steam. In any suitable manner 1 provide a rib and slot guiding connection between the cap 16 and the interior of the fitting 3. This is illustrated as consisting of grooves 19 in the outer face of the inner depending portion of the cap 16 and ribs 20 carried by the fitting 3 and projecting into the chamber 5. Such construction being employed, it is necessary to provide notches 21 in the member 6 so that the said member may be entered in the chamber 5 and fitted into its seat a before the cap 16 is placed in position. After the member 6 has 1 thus been located, the groove 21 may be filled,

' to hold the trunnions 26 in position.

below. the lower ends of the ribs 20, with some material such as Babbitt metal 22 so that the member 6 is then prevented from coming out of position.

One or more pin-and-slot guiding connections 23 may be employed to prevent the cap 16 from becoming detached from the fitting 3.

Referring to Figs. 1, a, 5 and 8, I there show locking or latching means for holding the cap in any position to which it may be depressed and correspondingly holding the valve 10 in any given position. The fitting 3 is provided with a rack 24: and the cap 16-carries a freely rotatable (except when checked) star wheel or pinion 25 which has trunnions 26 journaled in bearings 27 in the cap 16, pillow blocks or bearing members 28, held by suitable screws 29, serving So long as free to rotate, the star wheel 25 will 'not lock the cap, but immediately a check ing action is exerted on the star wheel, the cap will be locked. To that end I provide a latch 30 pivoted at 31 to a slight extension or lug on the side of the cap 16 so that the said latch may be swung to one side. The top 30 of latch 30 lies below the upper surface of cap 16. The latch is provided with an arm 32' which is pivoted at 33 and is adapted to swing in an outward direction only. The slight play that the arm 32 has, enables the star wheel to be caught in any position and consequently the cap can be held down to any point where it is depressed. The inclined arrangement of latch 30 (Fig. 4.) enables the arm to be released by mere downward pressure on the top 30 and when pressure is removed, the latch automatically restores itself to the locking position shown in Fig. 4:.

As a modified form of latch, I provide the construction shown in Fig. 15, where a pawl 30 is pivoted to the cap 16 and has a stop 30 which will engage the extension of cap 16 to which the pawl is pivoted and prevent the latch from moving so far over that it will not fall into the teeth at by gravity.

Normally the valve 10 is open. It may be partially or wholly closed by merely pressing the foot down upon cap 16 by which action the star wheel 25 turns outwardly or in a counter-clockwise direction (Fig. 5), thus swinging arm 32 outwardly and allowing free outward and downward movement of the star wheel. As soon as the pressure on cap 16 is removed, the expan-' sion of spring 15 causes a reverse movement of the star wheel 25 and the forcing of arm 32 back against cap 16, thus locking the star wheel and hence the cap 16 and valve 10. When the valve is closed, or partially closed, and it is desired to open it, merely touching the latch 30 with the foot will release the star wheel and thereupon the spring 15 will force the cap 16 upwardly and,through the connection let, 18, the member 6 will be turned and the valve 10 correspondingly turned open.

Referring now to Figs. 1, 3, 10, 11, 12 and 13, and particularly to Fig. 11, the interior of the shell 1 is provided with a rib 34 which "is continuous except at the upper part where and appear in full lines at the left of the gudgeon 36, while at the other side, or at the right, they are in dotted lines because they are in the opposite face of the rib. The rib is beveled away from the valve 10, as

shown at 37, such bevel being, in each instance, on the opposite side of the rib from the face which has the channels 35. The rib 34 at the bottom is cut away as at 38 to accommodate the hub 10 of the valve 10. The gudgeon 36 projects upwardly from the upper surface of the cut-away portion 38 and is provided with a collar 36 which fits in a concavity in the lower end of the hub 10*. The top of the cut-away portion 38, and consequently the collar 36 is above the level 1 of the interior of the shell 1 at the bottom thereof so that the pivotal connection of the valve is raised suificiently high to avoid access of condensation water thereto and I thereby eliminate danger of rusting in the pivots. To accommodate drainage of condensation water, I provide at one point only, the transverse channel 39 which is exposed when the valve is open so that the water can drain therethrough, but when the valve is closed, a rib or flange 40 carried by the valve, enters the drain 39 and closes it, Figs. 3 and 13.

The channels 35 are cross connected by channels 41 disposed near the cut-out portion 38. The lowermost channels 35 are extended and communicated at 35 with the cut-out portion 38.

The valve 10 is provided with ribs 42 which fit the channels 35, 41 and 35, such ribs being positioned and formed to correspond with and fit into these channels. At the upper end of the valve, Figs. 1 and 9,

' there are provided upright branch ribs -13 connected to the ribs 42, and the rib 34 has corresponding channels which bridge the channels 35 and receive the said ribs 43. Around the portion 9, the valve 10 is cut away as at 44 to receive the lower end of the member 6. This provides a sealed joint between the valve, its seat, and the turning device 6.

The ribs and channels obviate the necessity of using packing as they prevent the leakage of steam past the valve. If the steam leaks past one channel and rib re ceived therein, it is arrested by the next channel and rib. At the lower part of the valve, as will be seen from Fig. 11, and the upper part of the valve, as will be clear from Figs. 1 and 9, the upright ribs and channels in conjunction with the opposite or cross ribs and channels, prevent access of the steam to the pivotal points of the valve.

I do not limit myself to any particular cross-sectional outline of the channels and ribs which fit into them, nor do I consider it essential that the channels be on the rib 34 because the. shape of these channels and ribs may be varied and the ribs might be provided on the main rib 34 and the channels in the valve itself. Furthermore, the ribs may be formed integral or they may be attached parts connected either to the main rib 34 or to the valve 10. The rib 34 may be a separate unit attached to casing 1, instead of integral therewith. In Fig. 16, I have shown some of the cross-sectional shapes these ribs and channels may assume, but I am well aware that other forms could be resorted to.

On one side of the rib or flange 34 and on a given side of the pivot or gudgeon 36, the valve 10is extended down below the level of the-cut-away portion 38, as will be seen from Figs. 10, 12 and 13 and also in Fig. 1; the end of the valve, that is, the vertical edge appearing, Figs. 1 and 10, at 45 on the side nearest the observer and the corresponding part or edge being shown by dottedlines 46 on the far side of the rib 34. When the valve 10 is fully open, the relative appearance of the parts is as shown in Fig. 12 and when closed, as in Fig. 10.

Referring to Fig. 17, I have shown a modified operating mechanism for a reciprocating or globe valve. The cap 16 is directly connected to the stem 13 which carries the valve, not shown. The parts are shown in closed position with the spring 15 under full compression. It is desirable to employ a packing gland 47 for the stem 13 held down by plate 47 screwed down on turning device 6. The latch of either Fig. 5 or Fig. 15 can be employed.

In Fig. 18, the valve operating mechanism is preferably employed with the stem 13 of a reciprocating valve, the object being to not only move the stem longitudinally, but to turn it so that the valve will be seated by a grinding or twisting action and will be correspondingly unseated. The cap 16 is prevented from turning on the fitting 3 by the pin-and-slot connection 23 and it has riband-groove connections 19 with the fitting 3. It is adapted to impart a turning movement to the stem 13 by a spiral rib 14 en gaging a slot in the cap 16, as in Fig. 1. Ball bearings 48 may be interposed between the head 49 of stem 13 and the cap 16. When the cap 16 is depressed, it bodily shifts the stem 13 with its head 49 and at the same time imparts a turning movement to said stem 13 In the modifications of Figs. 17 and 18, the latching mechanism holds the valve fully opened, fully closed, or in any intermediate position.
