SPECIFICATION forming part of Letters.Patent No. 466,27 5, dated December 29, 1891.
Application file-d December 26, 1890. Serial 110,375,853. (No model.) i
To all whom it may concern:
Be itknown that'I, ERNEST C. FASOLDT, of the city and county of Albany, in the State of New York, have invented new and useful Improvements in Diaphragms for Pressure- Regulators, of which fieation.
My invention relates to improvements in the following is a specidiaphragms for pressure-reducers and other similar apparatus; and the object of my invention is to provide a diaphragm which, while having strength to withstand an extreme degree of pressure, will possess elasticity sufiicient to obtain a longer range of movement than is obtainable with an ordinary diaphragm capable of withstanding the same degree of pressure for which mine is designed. This object I attain by the mechanism illustrated in the accompanying drawings, which are herein referred to and form part of this specification, and in which Figure 1 is a vertical section taken at the central line of my diaphragm in its normal condition. Fig. 2 is a like section with the disks in their distended condition. Fig. 3 is a like. section on a reduced scale, showing a modified form of the guard for the disks.
Fig. 4 is a reduced plan view of another modiing'the valve mechanism.
As represented in the drawings, A designates the cylindrical body of a pressure-reducer, the valve mechanism for the latter being omitted therefrom, as it forms no part of this'invention.
l3 designates my improved diaphragm whiohis secured to the body A by a cap 0,
which is preferably attached to said body by. a screw-threaded neck D. Said diaphragm consists of twoconcentrically-corrugated me tallic'disks E, formed of resilient material and spaced apart by an annulus F to form a chamber G, into which steam orother fluid under pressure is admitted through an opening or openings 1, formed in the neck D. The disks E are made in the form of an annulus, and the central part of the lower disk lower faces of the diaphragmll.
is secured to the upper-end of the.neck D by means of an annulus 2, which is secured to said neck by screws 3, so as to clamp the central part of said disk between the upper end 5 of the neck D and the lower face of the annuhis 2. The central part of the upper diskis clamped, in the manner just described,,between the lower face of the hub H and the upper face of an annulus i by screws 5. An upper guard-plate I and a lower guard-plate J, of substantially the same form, are fitted to set over and form a guard for the corresponding disks E and to form the upper and Said guard plates are made dishing on the inner face to a degree that will conform to the limit of convexity required to be given to the disk by the pressure acting on theirinnerfaces. As shown in Figs. 1 and 2, the'concave face of each of said .70
Lwill, when the disks are bulged out by presslira-bear upon the surface of the dished side of the'guard-plates. The outer edge of the So guard-plates I and J, disks E, and annulus F are secured by bolts 6, which pass through the several parts last named, and packing rings 7 are interposed between the contiguous faces of said disks and annulus to form a'steam- 8 5 tight joint at those points.
It 'willibe seen-that the entire weight of the diaphragm 13 rests upon the upper end of the neck D, the latter remaining in a stationary position duringall changes of position of the other parts of thediaphragm. Preferably the lower disk is made thinner than the upper disk, so that said lower disk will more quickly yield to pressure than the upper one.
K designates an adjustingscrew which 5 passes through the central aperture of the neck D and hub II and projects beyond the outer end of said hub. A nut L is fitted on said screw to bear upon the upper end of the hub H, and a packing 8 is interposed between :00 7
said hub and nut for the purpose of forming a steam-tight joint at that point, so as to prevent escape of steam orother fiuid which may leak through the joint between thescrew K and the bore of the aperture through the hub 11. The lower extremity oft, the screw K is fully shown and described in Letters Patent No. 449,071, granted to me March 24, 1891;
but I do not limit myself to this form of valve,
with equally satisfactory results with many other forms of valves. K is provided for the purpose of adjusting the movement of the pressure-reducing valve to the position that will obtain the required reduction of pressure in the steam or other fluid whichpasses through the apparatus, or,
in other words, said adjusting-screw is de signed to eifect the setting of said'valve' in such manner thatwhen the extreme fluidpressure is prevented from entering into the apparatus said valve will be in the position required to have its closing movementproduce the required degree of reduction of press- 7 ure in the apparatus.
My invention'operates in thefollowingman- .Jier: The pressure in the body-of the pressure-reducer is admitted into the chamber- G; through the openings 1 in the stationary neck D, and-in said chamber said pressure .will act upon theinnerfaceof each disk E. 'lhe efieet of this pressure will-be to force [said disks to bulge outwardl y intothe forms shown in Fig. 2,,whereby. the lower guard.- plate J will be raised into contactgwith the lower face ofthe lowerdisk Eand the upper faeeof the upper disk E will be-forced into'eom taetwiththe lower face of the upper guard-'- plate I.- Thereby theentire diaphragm]; will be raised toa distance which corresponds to the concavity f'thelower disk andthe hub H willbe moved inrespect to the neck Die The adj usting-screwa distance that-equals the sum of the inovementsof both of said disks, the screw K ac quiring an upward movement that is equal to that of the hub I-l. It willbe seen that by this diaphragm, by reason of the disks E bulging in opposite directions, a much greater range vof movement of the valve '-,movi-ng mechanism can be obtained than with the single disk of an ordinary diaphragm.
' VVhatfI claim as my invention,and desire to secure by Letters Patent, isfor the reason that mydiaphragm can be used 1. In a diaphragm for pressure-regulators, the combination of two resilient metallic disks spaced apart by means of an annulus to forma chamber between them, one of said disks being centrally secured to a stationary neck provided with openings leadinginto said, chamber and the other diskbeing eentrallysecured to a hub arranged to movefrom and "toward said stationary neck, a pair of guardvent a rupturingstrain thereon, an adjustable rod connected to the movable hub, and means,
substantially described, for controlling the flow of fluid through the reducenasand for the purpose herein specified.
In? d aph agm t e omb nat on o a r silientsl sk' a aigua drpla e e gether at the periphery, said guard-plate havin a d sh ng form corr p to d k iitl d lying within the bulging'movement of the latter under pressure, whereby support isafiorded'tosaid disk to preventja rupturingstrainthereon, as and for the purpose h e n sp c fied- ERNEST o.
