VALVE:
- Specification of Letters Patent.
Patented Jan. 30,1906.
Application filed October 15, 1903. Serial No. 177,128.
To all w/iom it may concern.-
Be it known that I, MAURIoE D. LARKIN, a
. citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented a new and useful Improvement 1n Valves, of which the following is a specification, reference being had to the:
' accompanying drawings, forming part there- I X X of Fig. 1..
of, and in which the same characters of refer ence; designate like parts.
My invention relates to improvements in valves, and more especially to that valve for use under high pressure, such as in connection with fire hose, lire engines, hydraulic machinery,'&c. and it consists in the means, constructions, and combinations of the parts hereinafter described,and briefed in each of the appended claims.
vIn the drawings, Figure 1 is a central verti cal sectional view on line X X of Fig. 2. Fig. 2 is a central vertical sectional view on line Fig. 3 is a plan view of the movable portion'of the valveQ Fig. 4 is an enlarged plan view of one of the adjustingnuts. Fig. 5 is an enlarged bottom plan view of the spring member, and Fig. 6 is an enlarged elevation view of the adjusting-screw.
In said drawings, 10 represents the body of the valve, having passage-way 11 therethrough, and across said p ssage-way is revolubly mounted a cylindrical member 12, having opening 13 therethrough, adapted at tinres to register with said opening 11. Said member 12 is provided with trunnions 14, projecting from opposite ends and provided with suitable bearings in opposite walls of the valve-casing, and upon the ends of either or both of said trunnions, projecting beyond the valve-body, is mounted a handle or operating-bale 15, by means of which member 1.2 may be turned, so as to turn on or shut off the flow of water through opening 11in valvebody'10. The member 12 is of uniform diameter throughout its length, and the cavity in valve-body 10, in which said member 12 is revolubly-mounted, is also of uniform diameter and loosely fits the periphery and ends of said member 12.
In the periphery of member 12, at an an gle to the opening 13 therethrough, is formed acylindrical' cavity 16, within which is slidably mounted a cylindrical member 17, having on its. outer surface a plurality of raised rings 18 and 19, conforming to and closely fitting the curved wall of the cavity within which member 12 is revolubly mounted, the
ring 18 being slightly larger than the diameter of the opening 11 and being adapted to close the mouth of opening 11, leading from the valve-body 10. Said member 17 is prevented from turning in said opening 16 by pins 20, secured at a plurality of points about the edges of cavity 16 and fitting into recesses in the outer surface of said member 17, thus forming a suitable guide for permitting only an outward movement of said member 17 in a radial direction from the longitudinal center of member 12. The under surface of member 17 is provided with a cavity 21, and
between the bottom of cavity 16 and the top of cavity 21' is a spring 22, pressed against the bottom of cavity 16 by a screw 23, threaded through said member 17, whereby said member 17.. is not only spring-pressed against the curved surface of the cavity in valve;body 10, in which is mounted the member 12, but is adjustable therein by means of said screw 23, to compensate for wear as well as to increase thetension of the spring 22 whenever necessary to prevent leakage, said screw 23 being adjustable by means of a screwdriver introduced through the outlet-openin -11 in valve-body 10, which is surrounded y. thejustment may be simply and readily accomplished without removing any portion of the valve, as .well as when the valve is in use, sim ply by shutting off the water which brings screw 23 centrally into the nozzle end of the opening 11. As shown in Fig. 6, the screw 23 is povided on its lower end with a small portion 26, unprovided with threads, and the lower surface of this portion 26 bears upon thc s pring 22. This construction prevents the screw 23 from being raised into its threaded opening through member 17 sufficiently to contact with the inner wall of the cavity in valve body 10, in which member 12 is mounted, and in this respect the ring 19 on member 17, which surrounds said screw =threaded opening for screw 23, indicates to the operator by the relative positions of the head of screw 23 and the outer surface of ring 19 about how much more turning the screw 23 will stand without coming out of its opening and into cavity 16, or about how much more pressure the spring 22 will stand before a new one should be inserted.
In opposite endsiof member 12 and surrounding its trunnions 14 is a cylindrical cavity 30, leaving a relatively narrow ring 31 I re near the periphery of said member 12 at op- Frictionot the valve normallynis well under positc ends. surrounding each of said trunnions 14 a ring 32, of hard rubber or some other suitable material, adapted to bear against the relatively narrow inwardly-projecting ring 33 from the trunnion-bearing and projecting into the cavity of valvebody 10, in which member 12 is mounted. From the outer surface of the opposite ends of valvebody 10 and surrounding said trunnions 14 are screwthreaded openings 40, extending a portion of the Way through the walls of said valve-bod y 10, and each of said openings communicates with a relatively thin cavity 41 of larger diameter in said walls of said valve-body 10. These cavities 41 are for the purpose of rendering somewhat pliable the portions of the valve-body 10, having said rings 33 and the bearings for said trunnions 14, and said pli able ortions are acted upon by nuts 42, threaded into said openings and loosely surrounding said trunnions 1 1, said nuts -12 being adjustable by slots 43 in the outer ends of said nuts for the purpose of causing said rings 33 to bear against the opposite ends of member 12, represented by said rings 32, to compensate for any wear and at the same time to avoid leakage, said rings 32 being placed upon the ends of member 12 to avoid the disintegrating friction between like metals,
By the'construction ofmy apparatus and of the embodiment of the principles of m y invention valves are rendered readily and easily operative even under the highest possible pressure, whereas with other constructions they are packed so tight that they are hard to operate even when not under pres ,sure, and when under pressure they must be opened by the application of a long lever or.
by hammering the short operating-lever with which the valves are conveniently provided.
The preferred form of spring 22 is that of an umbrella-shaped disk of spring metal having a plurality of slots 50 extending from the periphery radially toward the center thereof, the convex side contacting with the screw 23 at its center and the concave side being toward the bottom of cavity 16 in member 12, with the edges of said spring-disk 22 resting upon the bottom of said cavity 16.
The absence of the usual packing necessary with other valves peculiarly adapts this valve for high-pressure service, such as for fireengines,as w ell as for use with chemicals of a more or less corrosive nature, in which latter case the difierent parts of the valve would be made of those well-known substances whiclrbest resist. the action of such chemicals.
The form of the arts and their construction is suchthat tie manufacturing cost is reduced to the minimum consistent with the highest efficiency, and at the same time the In each of said cavities 30 and i pressure, is almost wholly eliminated; but a relatively small friction-surface being provided only at such point or points where leakage is liable to occur, the remaining portions being free from contact with each other, the adjustment for wear being so great that the construction provided by my invention is highlyelficient, while other valves of like sur face. have been worn out and discarded.
Having now so fully described my invention that others skilled in the art may freely make and use the same when thisexclusive grant shall cease to operate, what I claim, and desire to secure by LettersPatent, is
