Application filed April 17, 1915.

To all whom it may concern Be it known that I, HALFDAN NoRoM, a citizen of the United States, residing at Bloomeld, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, andto characters of reference marked thereon, which form a part of this specification.

rlhis invention has reference, generally, to improvements in valves; and, the present invention relates, more particularly, to a novel valve for use with steam, water, air or gases, which is of such construction that under normal conditions, that is when the valve is closed, the outlet of the valve-casing is completely shut-oil' from the inlet of the valve-casing, or from the pressure in the inlet-side of the valve, but when partially operated, the outlet-side is'slightly opened to the inlet-side of the valve, so as to gradually equalize the pressure, and when iinally and completely operated, a full openingrelation of the outlet-side of the valve is had with the inlet-side of the valve.

The present invention, therefore, has for its principal object to provide a novel and simply constructed, as well as an effectively operating valve ot the general character hereinafter set forth and for the purposes herein above stated.

Other objects of the present invention not at this time more particularly enumerated will be clearly understood from the followingdetailed description of the said invention.

With the various objects of the present invention in view, the invention consists, primarily, in the novel valve of the general character hereinafter more fully set forth; and, the invention consists, furthermore, in the novel arrangements and combinations ot' the several devices and parts, as well as in the details of the construction of the said parts, all of which will be more t'ully described in the following specilication, and then finallv embodied in the clauses of the claim which are appended to and which torni an essential part of the said specification., v

The invention is clearly illustrated in the accompanying drawings, in which lFigure 1 is a longitudinal vertical section of a valve made according to and embodying the principles of the present invention, said view showing the normal initial position of the closing member or gate, and the means for operating the same, when the outlet-side of the valveis completely shut oii'1 from the inlet-side of the valve. Fig. 2 is a transverse vertical section of the valve, said section being taken on line 2-2 in said Fig. 1, logking in the direction of the arrow x, and the upper portion of the valve being partly shown in elevation. Fig. 3 is a horizontal section of the valve, said section being taken on line 3-3 in said Fig. 1, looking in a downward direction; Fig. t is a similar section of the valve, said section being taken on line Ll-fl in said Fig. 1; and Fig. 5 is a detail vertical section, taken on line 5 5 in said Fig. 1. Fig. 6 is a sectional view, similar to that shown in Fig. 1, but illustrating the slightly raised position of the closing member or gate, and thev means for operating the same, illustrating the slightly opened relation ot1 the outlet-side of the valve to the inlet-side of the valve. Fig. 7k is a transverse vertical section of the valve, said section being taken on line 7e-7 in said Fig. 6, looking in the direction of the arrow y, and the upper portion of the valve being partly shown in elevation. Fig. 8 is a horizontal section of the valve, said section being taken on line S-S in said Fig. 6, looking in a downward direction; Fig. 9 is a similar section of the valve, said section being taken on line 99 in said Fig. 6; and Fig. 10 is a detail vertical section, taken on line 10-10 vin said Fig. 6. Fig. 11 is a longitudinal vertical section of the valve, showing the position of the closing member or gate, when turned into a plane at right angles to the plane of the closing member or gate represented in said Fig. 1, to provide a completelv opened passage between the outlet-side and the inlet-side of the valve; Fig. 12-is a vertical section of the valve, said'secti on being'taken on line 12-12 in said Fig. 11; Fig. 13 is a horizontal section of the valve, said section being taken on line 13-13 in said Fig. 11; and Fig. 14e is a similar vertical section.v taken on line 14-14 in said Fig. 11. Similar characters reference are emclearly evident. shell 2 is made with a downwardly extendv23. 'the said stem or spindle, and to at all times ployed in all of the said above described views, to indicate corresponding parts.

Referring now to the said drawings, the reference-character 1 indicates the complete valve showing one embodiment of the principles of the present invention, the same comprising a suitably-shaped main valvecasing or shell 2, formed at one side with an inlet-element, as 3, which may be formed with the usual flange 4, or other suitable meansfor 1the attachment thereto of a pipe,

and formed at its opposite lside with an outlet-element, as 5, which may be inter-v nally screw-threaded, as at 6, or may be provided with other suitable means, for the at taohinent thereto of another pipe, as will be The said valve-casing or ing receiving portion, as 7, formed with a seating portion 8, and a pair of socket-like parts 9 and'10, said socket- like parts 9 and 10 beingin alinement longitudinally of the `valve and being located in the central and longitudinally extending vertical plane of `'the valve. Resting upon said seating portion '8 is a correspondingly formed disk', as

11, formed with opening, as 12 and v13, respectively, in registration with the socketlike parts 9 and 10. The'said receiving portion 7 is also provided with a screw-threaded hole, as 14, into whichis screwed the screwythreaded end-portion 16 of a stop-pin or stud, as v15` the shank of the said vpin or "stud extending through a correspondingly placed hole cr perforation 17 in the said 'disk 11, substantiallyas shown in Figs. 1, 6 and 9 of the drawings. valve-casing or shell 2 is also made with an The said main upwardly extending cliambered member, as 18, which is provided at two points, adjacent tofthe outlet opening of theoutlet-element 5, with seats, as 19. Upon its upper -outer portion, the said member y18 is pro-- vided with a'screw-threadedpcrtion'20 upon which is screwed a suitably formed *closing 'cap,las'2l,`having a centrally disposed bearing-portion 22 forthe proper reception and rotatif-n therein 'of a -valvestem or; spindle To prevent any vertical movement ot maintain the saine in its rrtatable operative relation,`the said member 18 is also formed with'an interiorly disposed annular off-set,

vas 24, which forms a suitable seat for the disposition thereon of a retaining disk Vor plate25, said plate 25 being positively held in position upon said cit-set 24, by bringing in retaining Contact with the marginal edgeportion of said-disk or plate 25, the inner annular surface-portion 26 of the above- Vmentioned closing cap 21, substantially as illustrated in Figs. 1, 6 and 9 of the drawings. The said disk or plate 25 is also provided with a centrally disposed hub, as 27,

formed #withfa "centralopening t whiohw-is inlteriorlv screw-threaded, as at 28, Screwed threaded nut or collar-like element 34-which is mounted upon the shank-portion 'of the vstein or spindle 23, directly -above the said annular rib 32, and when screwed in position thus prevents any vertical 'movement of the spindle or stem 23, without interfering with the rotating movements of the said spindle or stem, as will be clearly understood from an vinspection of said Figs. 1, S

6 and 9 of the drawings. The said cap 21 is also provided with an externally vscrewthieaded projection, upon which is mounted 'a stuffing-box, as 35, of any usual'construction, for packing the stein or spindle 23 at that point, and to provide a tight joint. The lower portion of theshank of the said 'spindle or stein 23,Y is screw-threaded, as at 36, and isalsoprovided with a laterally extending stud or projection 3 7.V Upon lits upper freeend-portion, the said spindle or stem'23 is yinade with Va polygonally-shaped end, as 38, for the reception of a wrench'- like'handle thereon, by means of which the said'steni or spindle may be turned for opening and 'closing the valve, as 'will be understood. Other means, however, such as a hand-wheel, cr the like,may beemploye'd in connection with the upper end-portion of .the 'said stein o-r spindle .for turning the same, if desired.

The reference-character Q39 indicates 'a suitably lformed and *vertically 'disposed closing member 'or gate, inthe form of an 'arc-sha'pedweb, the outer 'curved surface v4() -of which tapers,substantiallyV in the manner shown in` Fig. 1 'ofthe drawings,`said curved surface, under normal condition,

when the valve -is closed, registering with and being in contact with the previouslymentioned seats 19 and an arc-shaped seating yportion 41 in the inner-lower portion of the valve-casing 2, at a point 'directly below the innervpart of the outlet-member 5. EX- tending horizontally from the upper portion of the said arc-shaped web 39, forming the said closing-member or gate, is a member 42 formed with an internally screwthreaded hole or opening 48 in alineinent with the valve-stem or spindle "28,

Aand into which fthe screw-threaded portion 36 of the said stein or spindle is zoY screwed, as shown, and whereby the said stem or spindle and the closing member or gate 39 are operatively connected. The said member 42 is also provided with a hole or opening 44 forming a spindle or pin-receiving portion for the purposes to be presently set forth. Similarly extending horizontally from the lower portion of the said arcshaped web 39, forming the closing member or gate, is another member 45, said member being provided upon its lower surface with ardownwardly extending pivot-stud or lug, as 46, which extends into and through the centrally disposed opening 12 of the disk or plate 11, and into the socket-like part 9 of the receiving portion 7, of the main valvecasing or shell 2, substantially as illustrated in the several figures of the drawings. The said member 45, as will be seen from an inspection of Figs. 4, 9 and 13, is cut away, as at 47, and is provided with a pair of horns or stop-projecticnsv48 and 49, adapted to be brought into arresting engagement with the previously-mentioned stop-pin or stud, substantially as shown and for theV purposes lto be hereinafter more fully described. The

said member 45 is also provided with a hole or opening 50, 1n alinement with the hole or lopening 44 in the member 42, and mounted in the said holes or openings 44 and 50 are the respective end-portions of a pin or spindle 51. This pin or spindle 51 has suitably mounted thereon, in a fixed position, a sleeve or collar 52, resting upon the upper surface of the said lower member 45, so that the lower end-portion of the said pin or spindle 51 extends into and through the opening 13 of the disk or plate 11, and into the socketlike part 10 of the receiving portion 7 of the main valve-casing or shell 2, as shown. Encircling that portion of the spindle or pin 51, between the lower surface of said upper member 42 and the said fixed sleeve or collar 52 is a coiled spring 53, the purpose of which is to provide a spring-controlled stop for locking the valve-gate 39 in its closed relation, as will be self-evident, and at one side of the hole or opening 13 in the disk or plate 11, the bounding surfaceportion of said disk or plate 11 is inclined or cut away, as at 54, see Fig. 6 of the drawings, and the purpose of which will be presently fully set forth.

Having in the foregoing described the general construction and arrangement of the several devices and parts comprising the valve-construction, I will now briefly set forth the manner of working the valve and the operations of its parts for the purposes stated in the introduction of this specification.

VVhen the several devices and parts of the valve are in the respective positions indicated in Figs. 1 to 5 inclusive, then the arcshaped -webor closing gate 39 completely shuts off the inlet-side from the outlet-side of the valve. As socn, however, as the spindle or stem 23 receives its initial rotary moticn, from right to left, then the screwthreaded portion 36 of said stem o'r spindle will cause an upward movement of the said arc-shaped web or gate 39 from its closing position shown in Fig. 1 to its vertically raised position indicated in Fig. 6 of the drawings, the lower end-portion of the spindle or pin 51, while still extending into the receiving socket-like part 10, preventing any rotary or swinging action of the said arcshaped web or closing gate 39, as will be clearly eviden-t. The upward movement of the said web or gate 39, causes it to become unseated from the seat-portions within the main shell or casing 2, so that the pressure within the valve-casing or shell 2 will beco-me equalized upcn beth sides of the raised web or gate 39. The further rotary motion of the valve-stem or spindle 23, from right to left, brings the lower end-portion of the pin or spindle 51 into the opening 13 in the disk or plate 11, and the end-portion of the pin or spindle 51 will ride up the inclined surface 54, and there being no further oppositicn to a swinging movement of the pin or spindle 51, about the pivot-stud or lug 46 as a center, the stud or projection 37 of the stem or spindle 23 at the same time having been moved into contact with an extension or post 56 with which the upper member 42 is provided, as clearly shown in Figs. 11 and 12 of the drawings, whereby the active cooperation of the screw-portion 36 with the member 44 being arrested, and the said web or gate 39 is swung around into its entirely opened poisticn indicated in Figs. 11V and 13 of the drawings, thereby providing an unobstructed full passage-way between the inlet-side andthe outlet-side of the valve, as will be clearly understood. The previously-menticned stop-projections or horns 48 and 49 being respectively brought into contact with the stop-pin or stud 15, arrest the said closing web or gate 39 in either its fully opened or fully closed positions.

In turning the valve-stem or spindle 23 from left to right, the operations are reversed, the spring 53, as soon as the spindle or pin 51 is again moved above the register-- ing openings 13 and 10, causing the lower end-portion of said spindle or pin 51 to be again forced into locked engagement with said openings, so that the closing web or gate 39 is positively retained in its closed relation with the outlet-end of the valve, as will be clearly understood.

Of course I am fully aware that some changes may be made in the general arrangements and combinations of the several devices and parts, as well as in the details of the construction of the said parts, without departing from the scope of the presentinvention asset Yforth in the'fore- 'goingspecificatiom and as defined in the "clauses of the `claim which are `appended v'to lthe said specification. `Hence7 I do not limit the present invention to the exact arrangements and combinations of: the several 'devices and parts as described in the said specification, nor do confine myself to the exact details of the constructionof the said'parts as illustrated in the accompanying drawings.V
