F. D. HOLDSWOR'H I VALVE MECHANISM Original Filed Dec. 31, 1925 Patented July 1, 1930 seine FRED D. HOLDSlK ORTI-I, OF CLAREMONT, NEW HAMPSHIRE, ASSIGNOR TO SULLIVAN MACHINERY COMPANY, A GOBPORATICN OF MASSACHUSETTS VALVE MECHANISM Application filed December 31, 1923, Serial No. 683,605.

This invention relates to valve mechanism.

It has for an object to provide an improved valve mechanism. A further object is to provide an improved plate valve mechanism which provides an unusually large inlet or discharge area. Another object is to provide improved plate valve mechanism in which the movement of the plate valve can be exceedingly small, but which will nevertheless provide ample discharge area. Another obj ect is to provide improved valve mechanism in which a plurality of plate valves may be used and operated in angularly disposed planes. v

In the accompanying drawings I have shown for purposes of illustration one form which my invention may assume in practice. In these drawings,

Fig. 1 is a plan view partially broken away 20 to show details of construction.

Fig. 2 is a vertical section on line 2-2 of Fig. 1.

Fig. 8 is a vertical section taken at right angles to Fig. 2 and on line 3-3 of Fig. 1.

Fig. 4 is a section taken on line 44 of Fig. 1.

Fig. 5 is a plan view of a plate valve used in the illustrative form of my invention.

Fig. 6 is a plan and side elevational view 30 of a valve spring which may be used in cooperation with the plate valve of Fig. 5.

In my improved valve mechanism I propose to use a plurality of plate valves disposed in diflerent angular planes and in a common cage member, thus making a very compact device. To accomplish this I have shown for purposes of illustration one embodiment of my invention which comprises a base 1 having an annular flange 2. Disposed in the base 1 are spaced longitudinal rib-like members 3; and valve seats 5 are formed on the upper surfaces of said'members. The spacing of these members 3 results in upwardly extending passages 4 being formed between or beside them. Transverse strengthening ribs 6 connect the various ribs 3 and flange 2. Ports 8 are formed between the members 3 so as to constitute continuations of the passages 4. The rib-like mem- 5 hers 3 are hollow, with open tops, as is made Renewed October 29, 1929.

clear by Fig. 2. From Figs. 8 and 4 (noting particularly where these sections are taken) it will be understood that transversely disposed ports 7 project inwardly from each of the passages 4. Vertical valve seats 9 are formed in the interior of the rib-like members 8 surrounding the ports 7 V and extend, as shown in Figs. 1 and 4, between opposite inner points of the annular flange 2. The base 1 may be seated in a cylinder 12 by any suitable means (see Fig. 3), herein shown as a shoulder 13 formed in the periphery of the annular flange 2.

The valves for covering the horizontal valve seats 5 comprise a single circular resilient plate 14 having parallel slots 15 leaving the strips 17 in between. Thus,these valve portions 17 when placed upon the upper surface of the base 1 will cover the various ports 8 while the openings 15 leave ampleroom for discharge through the ports 7. The circular plate 14, and consequently the valves 17 is held in position by a transversely flexed spring 19 with its end portions slightly upwardly curved, which in turn is held in position by a cover 20 having a depending annular portion 21 adapted to seat adjacent the upper circular edge of the base 1- and which is held in fixed relation thereto. Any suitable means may be used for holding the cover 20 and base 1 in fixed relation, such means herein shown as bolts 23 screw threaded into the base 1. It is not thought necessary to describe the details of the clamping structure for holding the elements of the valve mechanism in assembled relation on the shoulder 13 of the cylinder, as it is of a well known type. The cover 20 is spaced from the surface 5 and has openings 24 therein for allowing flow of fluid from the ports 7 and 8. The spring 19 is disposed within this space and held in coaxial relation with respect to the valve as by depending lugs 25, the outer surfaces of which are'curved to fit the inner edge of the spring 19. The lugs 25 are also adapted to assist in guiding the valve 14, these lugs projecting downwardly within the central opening 15 and seating upon the upper surface 01' the base 1.

I a leans for closing the ports 7 comprise re silient plate valves 26 and as shown in Fig. 1 a single transversely curved spring 27 is used to seat the pair of opposed plate valves 26 disposed over the opposed valve seats 9. Thus, the central portion of the spring 26 engages the left hand valve while the outer en s of the same engage the right hand valve.

In the operation of my device it will of course be understood that my valve as shown can be used either as an inlet or exhaust valve and when used in either manner fluid will flow through passages 4, and valves 17 and 26 will be opened in accordance with the amount of fluid flow through the passages 4. It will be readily seen that the distance the valves 17 and 26 move will not be as great in order to allow a given amount of fluid flow as'though only valves in a single plane .were usedand hence my improved construction permits a very rapid action of the valve and a large flow of fluid therethrough without producing any hammering action or other isadvantages that are inherent with valves thatmovea great distance from their seats. It willbeseen that upon removal of the valve mechanism from the cylinder 12, the various plate'tvalvesca'n be maintained in their seated positions without the necessity of any special mutations to prevent the various members rom'separating.

While I have in this application specificallyidescribed one form which my invention may assume in practice, it will be understood thatthis form of the same is shown for purposes of illustration and that the invention ma: be modified and embodied in other forms wit out departing from its spirit or the scope of the. appended claims.
