vlloc/ZZ whom t may concern.-
"13 "Be it known that I, lYlAn'riNl A. TiiinL, a citizen of the United States of America, re-
si'ding at Milwaukee, in the county of Mil- -gi`'waukee and State of Wisconsin, have invent- 'edcertain new and useful Improvements in Single-Piece,Spring-Valves, of which the following is a specification. This invention relates to spring valves and ilo has for an object the production ofa flap valve of simple construction which will be effective and accurate in operation.
` A further object is the-production of a .2 :fval'vet this class which will move rapidly isgand act positively and still answer to the 'slightest variations of the actuating pressure. A ditticillty encountered 'in valves of this 'z' class has been the tendency of the valve )ring to break, diieto an unequal distribu- 2 0 ion ol` the distorting strainsthroughout its ength. In overcoming this ditliculty my ob- "ject has been to construct a' valve that will be durable and fat the same time cheap to manufact-rire.'
' These and; other objects attain in a valve "ing my invention. vFig. 2- is a section along f the line AA f Fig. '-1.
embodying the features herein described and illustrate y 1 In the single'slieetof drawings accompanying this applicationand forming a part thereof, Figure 1 is a plan view of a valve embody- Fig. 3' is a section along the line BB of-Fig. 2. Fig. 4 is a plan view at a reduced scale of the valve with 3 5 the springportion developed oruncoiled.
The springf'valve consists of an integrally formed valve portion 5,- spring portion 6 and a niounting'portion 7, and is of such simple construction that it may be stamped or cut out ofa metal blank of uniform thickness. A centrally located and longitudinally eX- tending slot 8 is cut in the spring portion 6 between the valve portion 5 and the mounting portion 7 and this slot is widest at a point in bending moment encountered throughout 'its length, so that each portion of the spring adjacent to the portion 7 and tapers toward will deflect or give an eqnalamount. 'In
otherwords, the spring is so constructed that the portion' encountering the smallest bending stress is Iliade weakest and the portion encountering the greatest bending stress'is made the strongest, and the sectional area is proportioned throughout the length of .the spring in accordance with the encountered stresses so that the strains cross bending are substantially equal along tliel'ength of the spring. After :the spring is stamped or cut from the blanktlie valve and mounting por- 'tions may be given any desired contour and the outer edges of the spring portion and adjacentanounting members. By gradually reducinv the eflective area of the springportion thebbending or distorting strain is equally distributed throughout the length oi the spring and an equal'distortion of the separate coils is obtained and they will therefore always act independently of each other and not contact or bind; f
In Figs. 1 and 2 the spring valve is shown mounted on an arbor 10 and adapted to control the flow of fluid through ports 1l of a valve seat 12'. is adapted to be opened by fluid pressure eX- erted on the under side of the valve portion 5, and by properly proportioning the width of the slot 8 the strength of the spring portion relative to the strength ofthe valve portion 5 -Inay be made such thatI the spring portion will distort sufficiently to open the valve any desired amount before the'valve portion 5 is subjected to an appreciable stress. Moreover, by tapering the slot so as to decrease the cross sectional area of the spring in proportion to the bending or distorting strains encountered throughout its length each coil will yield equal amounts and therefore a flexible spring and an active and positive valve is obtained. In spring' valves in which the strength of the spring portion is not made considerably less than that of the valve portion it has been noted that the valves break adjacent to the point of merger ofthe valve and spring portions. This fracture is due to ericessive strains encountered at that point. and the tendency to fracture is overcome in a valve constructed in accordance with my in- The valve herein illustrated IOS IIO
vcntion by relieving tlie valve portionv ol' bending strains and proportioning tlie ell'ect.- ive area of tlie spring to tlie distorting strains eiuzountcreil along its lengtli. 'llie spring portion ol' tlie valve maybe ol` anyilesii-eil wiiltli and may be provided with two or inoi'e weakening slots; the mounting and valve portions may be olv any desired sliape and contour and many and various changes may be maite in tliecoinbination anal still fall within tlie limits aiul scope ol'iny invention.
What l claim as new and usel`ul is:
l. ln a \alve, a plane valve portion and a coil spring support tlierelor liaving a central loi'igitiuiinal part cut away in increasing amount. at increasing distance from the valve portion. i
3. A spring valve comprising an integrally l'ormezl valve portion, a spring portion providedl witli a longitudinally extending and tapered slot and a mounting portion.
3. A spring valve comprising an integrally formed valve portion, spring portion and mounting portion til-equal thicknesses, t liel spring portion lwingcut away longitudinally aiul increasingly from tlie valve portion to compensate the variations in tlie distorting strains.
4. A spring valve coniprising an integrally I'ormeil valve portion, spring portion and mounting portion, tliespring portion being 'cut away longitudinally anti increasingly from, tlie valve portion to coiiipeiisate tlie vai riations in tlie distorting strains.- i
5. A blank for a single piece valve coni- )rising a substantialll rectilinear stri) of slieet metal, a vaive portion at one end, a mounting portionat tlieI otlier end autl an intermediate spring portion wliicli is cut away longitudinally and increasingly from tliey valve portion toward the mounting portion.
A blank fora single piece valve coinpris'iug a substantially rectilinear strip ol' metal, a valve portion at one end, a niounting portion at'. tlie otlier enzl anrl an interineliate spring portion wliicli is cut away centrally, longitudinally and. increasingly from the valve portion toward tlie mounting portion.
7. A blank for a single piece valve coinprising asubstantially rectilinear strip ofA slieet inet:.l, a, valve portion at one end, a
mounting portion at tbe other end and anintapered` y
