DIAPHRAGM.

Specification of Letters Patent.

Patented Apr. 4, 1911.

Application filed November 18, 1910. Serial No. 593,019.

To all whom it may concern:

- Be it known that I, JOHN H. KINEALY, a citizen of the United States, residing at Ferguson, in the county of St. Louis and State of Missouri, have invented a new and useful Improvement in Diaphragms, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to diaphragms, particularlymetal diaphragms, used in connection with thermal and other motors and other devices such as water, steam, and gas regulators where it is desirable to use a diaphragm that is capable of considerable motion and that'iequires only a slight pressure to make it move.

.The object of my invention is to provide a diaphragm that can be stamped or ressed out of a single piece of metal; and a rther object of my invention is to provide a diaphragm that will be of low cost and yet which will be capable of considerable move-v ment without injuig; I

My invention is 11y shown in the accompanying drawings where similar letters are used to desi ate similar parts.

Figure 1 1s a view of one form of my im proved diaphragm forming the upper part of a motor operated b internal pressure; Fig. 2 is a vertical section of 1 on the line 22; Fig. 3 is a vertical section of Fig.

1 on the line 3--3; and Fig. 4 is aview of another form of my diaphragm" applied tothe same motor used in Fig. 1.

Referring to the figures, A represents wings which form the diaphragm, each of which has a straight attached to thefsides about which it may turn through a small angle. 0 represents corrugations or deprese u e B by which it is sions whose walls are flexible, lying between the adjacent edges (1? and a. of the wings.

.D is a central piece, lying inside of the inner ends or edges of the wings A.

"E represents depressions or corrugations whose walls are flexible, lying between the edges 42 of the central piece D and the inner edges a of the wings A.

The straight edges B of the wings are arranged with respect to one another so that they form a polygon as illustrated in the figures of the drawings where the edges B form a square; and the adjacent edges a and a of adjacent wings diverge from the of the motor and corners of the polygon toward the center thereof. The corrugations C increase in depth from the corners of the polygon toward the center thereof, and where the corrugations or depressions C meet the corrugatlons 0r depressions E the depressions G are preferably of the same depth as the de ressions E.

he wings A and the central pieee Dma be made of stiff, rigid material provide however, the strai ht edge B of each wing is so arranged that the wing may turn about it through a small angle. The walls or sides ofthe depressions C and E must, however, be sufficiently flexible as to'give'when the wings are made to turn about the straight sure. When the fluid flows from its source of supply through the pipe N into'the motor it presses against the sides and bottom thereof and also against the diaphragm which forms the top of the motor, as shown in Fig.

- 2. Because of the internal pressure exerted on them the wings A are made to turn about the straight edges B and the diaphragm is raised and assumes the position indicated by the dotted lines in Fig. 2. The walls of the depressions E give so as to allow the inner edges a of the wings to be separated some what from the edges (1 of the central piece D; and the adjacent edges a and a of adj acent wings separate somewhat and the flexible walls of the depressions G give so as to allow this separation of the ad acent ed es of the wings. When the pipe N is isconnected from the source of supply of fluid under pressure, the pressure inside of the motor is reduced and the diaphragm returns to its original lines in Fig. 2.

It is evident that my invention may be embodied in a diaphragm having any numposi'tion shown by the full ber of Wings, provided always that each wing has a straight edge about which it may.

turn.

What I claim as new and desire to secure by Letters Patent, is:

1. In a diaphragm, a plurality of wings each of which has a straight edge about each of which has a straight edge about which it may turn, a central piece, and a flexible member connecting-the wings and the central piece, substantially as described.

3.*Ine a dia ragm, a plurality of wings each of which has a straight edge about which it may turn, said straight edges being arranged w1th respect to one another so as to form a polygon with the wings lying inside thereof and the adjacent e ges o the wings diverging from the corners of the polygon toward the center thereof, and a flexible member connecting said wings in such .a way that they may simultaneously turn each about its straight edge, substantially as described.

4. In a diaphragm a plurality of Wings each of which has a straight edge about i which it may turn, said straight edges be ing arranged with respect to one another so "as to form a polygon with the wings l'ing inside thereof and the-adjacent edges 0 the wings diverging from the corners of the 1 polygon toward the center thereof, a central piece, and a flexible member connecting the wmgs-and the central piece, substantially as desclibed. d .h 1 1- r 5. 11 av ia ragm a p ura ity of wings each of whic has 5 straight edge about which it may turn, said straight ed es being arranged with respect to one anot er so as toform apolygon with the wings lying inwings diverging edges of the wings,

wings diverging from the corners of the polygon toward the center thereof, corru'ga-- tions connecting the adjacent edges of the i wings, the depth of 'sald corrugations increasing from the corners of the polygon toward the center, a central piece, and corrugations between the central piece and the inner edges of the wings, substantially as described. 1 f

6.
