ALVACURT'IS RICKSECKER, CHICAGO, ILLINOIS.
. vanvia Speccation of .Lett-ers Patent.
Patented July 13, 1909.
Application led iai-cli 25, y1908. Serial No. 428,095.
To all whom it may concem:
Be it known that I, ALvA CURTIS RICK- sEoKER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements'in Valves, of which thel followin is a specification, reference being had to t e accompanying drawings, forming a art thereof. l
he purpose of this invention is to provide an improved construction of valves of the type'or class comprising a rigid head or diskho der to Which a stem is connected and a spring disk which constitutes the seating element and is removably secured to such head or holder.
The invention consists in the features of construction'shown and described as indicated in the claims.
In the drawingsr-Figure 1 is a section axial with respect to the' valve stem of a valve structure embodying this invention. Fig. 2 `is a detail section at the line 2-2 on Fig. 1. 3 is a side elevation of the spring disk. Fig. 4 is a detail section at the line 4 4 on Fig. l.
In the drawings I have represented my invention as app ied to an ordinary screwdown valve in which the body, A, has a tapered valve seat at B, and the valve head comprises a holder C, on which is mounted a removable disk, l5, having an annular portion, D1, which is concave-convex, the conveX side being exterior and forming the seating face for contact with the tapering seat, B. In practice, the entire disk may be concavo-convex in radial or diametric section, as shown in the drawings, but the concavoconvex form of the portion of the disk l ing within the seating area is not particu arly signicant, so far as this invention is concerned. The valve head or disk holder, C, is connected with the stem, E, for permitting the rotation of the stem without rotating the valve head and allowing the valve, within a limited range, to accommodate itself to its seat. For this u ose the u per side of the valve head or isli'liiolder, C, as a cylindrical ocket, C1, which receives the cylin drical ange, El, which terminates the stem, E. At a distance above the bottom of the pocket, C1, slightly more than the thickness of the terminal flange, E1, of the stem, the wall of said pocket has at each side an a erture, el, for receiving a U-shaped o'r for ed key, F, which is inserted through such apertures, striding or receiving between its side bars the valve stem and passing above the terminal flange, E, the fork ends extending out at one side and being slightly bent up'or dowir for retaining the key in place, the edge being straightened whenever it is desirab to Withdraw the ke to permit the stem to be separated from t e head or holder, C.
In the use of removable valve disks herotofore, the have generally been secured t0 the valve hea at the center where the threaded stem and nut, or equivalent devices, have been employed for securing them. Such construction involves the necessity of making a {luidtight joint between the disk and head or disk-holder around `a central stem or bolt, and involves a further objection that any device used for securing the disk in such position is liable to become loosened and escape and be carried back through the fluid passage into the mechanism with which the valve is connected, involving danger and serious damage to the latter. The present invention constitutes one means'of providing a disk without a central aperture and requiring no such central-securing device, but having in all respects the full advantage which pertains to a removable spring disk. In order that the disk may be positively forced on to its seat when the valve is closed, and also that it may be definitely centered on the, holder, the latter is peripherally rabbeted, the disk having its marginal ortion c lindrical for fitting around the cylindrical shoulder, c, formed by rabbeting, and being stopped against the annular shoulder, c5, thus formed. This construction, it will be observed, leaves the annular concavo convex seating portion of the valve disk free to yield elastically to the pressure which forces it on the seat, and thereby free to accommodate itself to the seat, which is the rimary purpose of the spring disk. In tie form of the device shown, the disk has no backing or support Within the seating area, the advantage of this construction being that thereby the disk is afforded the maximum elasticity, the entire portion which closes the aperture in the valve contributing its elasticity, as Well as the annular seating portion. In order that this disk may be secured to the holder removably and without risk of accidental detachment of the securing device, the cylindrical marginal portion of the disk is provided with a number of apertures (Z1- preferably six or more-, and the holder is esmas r provided with a corresponding number of `ends to the marginal apertures of the disk,
correspondingly distributed apertures, e,Y
which extend radially into the cylindrical shoulder, c", said apertures being arranged in pairs to receive the rongs of three Wire staples, G, Whose sai prongs are deflected from their original and normal parallel position into converging position as they pass into the radial and therefore converging apertures, ce. The convergence ol' the prongs when the staples are thus driven into place prevents the staples from escaping, but they may be readily withdrawn for dctaching the disk When necessary `for substituting a new one. Preferablythe holder is provided with a slight marginal bead or flange, C4, projecting from its face encompassing the diskand operating to check its expansion When pressed upon its seat, and thereby prevent any danger of bursting the disk. The crossbar or bridge of the staples, G, does not pro-Vr ject beyond the thickness kor vvidthy of the flange, C4, and .therefore the presence of the staples does not increase the size of aperture in the body or cap necessary for admittingk the valve to its seat.
I claim 1. In a valve of the class indicated, a valve head comprising a disk holder and a thin metal disk detachably vsecured to the holder and forming the seating element of the valve, said disk being lodged against rthe holder in contact therewith at a line or arca outside the seating area, said disk being out of contact With the holder atand within the seating area, the sole securement of the disk tothe holder being outside the seating area.
2. In a valve, in combination, a valve head having a round pocket at the back or upper side; a stem terminating ina transverse disk `adapted to be inserted in suchpocket by axial movement,` the Wall of the pocket being apertured transversely to theaxis of the pocket at a distance from the bottom approximately the thickness of the terminal v disk of the stem, and a forked or U-shaped key inserted through such apertures striding the stem above the disk. A
3. In a valve of the class indicated, a valve .head comprising a disk holder and a thinl `metal disk detachably secured thereto and 1 forming the seating element of the valve, the
disk being unapertured Within the outer circumference of the seating area, but having marginal apertures in airs outside said seating area, the holder eing provided with a shoulder for centering the disk thereon, said shoulder having pairs of non-parallelA apertures corresponding in position at their outer.
and staples having their prongs entered throughthcrespective pairs of a ertures in the holder for connecting the isk to the holder.
4. In a valve of the class indicated, a valve head comprising afdisk holder and a thin metal disk detachably secured thereto and forming the seating element of the valve, the
disk being unapertured Within the arca` the disk thereon, said shoulder having radial apertures in pairs leading in from its surface colnciding attheir outer ends 'withv the pairs of apertures of the disk, and staples having their prongs entered through the respective pairs of apertures of the disk and extending into thek corresponding pairs of 'a ertiires Vef isklto the the holder fork eonnectlng the holder.y
5. In a valve of the class indicated, a valve head comprising a disk holder anda thin metal disk detachably secured thereto and forming the seating element of the valve, the disk being unaperturcd Within 'the area bounded by the outer circumference of the seating arca, but having marginal apertures outside the seatino' area, the holder being formed with a shoulder for centering the disk thereon and anannular shoulder for seating the edge of the disk, said shoulder having apertures' corresponding in position to the marginal apertures of the dlsk, and means taking through the apertures of the disk into the corresponding apertures of the holder for connecting the disk to the holder.
6. In a valve, in combination', a valve head having a round pocket at the back or upper side; a stem having a transverse'y terminal disk loosely fitting the pocket, adapted for aXial insertion therein, the Wall of tle pocket being transversely aperturedat opposite sides of 'a plane above the bottom of the pocket a distance suiicient to accommodate the disk, and a forked key, inserted throu h the aper- Vture above the disk embracing t e stem, and
adapted tol have its ends kflexed for engagement outside the pocket Wall.
In testimony whereof, yI have hereunto set my hand, in the presence of two Witnesses, at Chicago, Illinois, this 23d day of March, 1908.
