FFGGL Fifia u HTNESSES INVENTOR Alild TE VALVE FOR BLOWING-ENGINES, 8w.

Specification of 'Letters Patent.

Patentedfict. 1'7, 1916.

Application filed February 24. 1914.. Serial No. sense.

To all whom. it may concern:

Be it known that I, Lonnxz Ivnnsnv a citizen of the United States, and a resident of West- Homestead, in the county of Alle- 5 gheny and State of Pennsylvania, have invented certain new and useful Improvements in Valves for Blowing-En ines, &c., of which the following. is a specification.

T his invention relates to valves for blowing engines, compressors, pumps and other machines variously employed for manipulating gases and liquids, and more particularly to certain variations in the construction shown in latent No. 1,012,359, granted to inc December 19, 1911, and in my applicacation filed February 18, 191%, Serial No. 819,405.

The primary object herein is to provide improved means for uniting the valve and spring, such means being located wholly between those edges of the spring which are parallel with the plane of movement of the valve, so that in the coil form here illustrated no portion of the securing means protrudes beyond either the inner or the outer periphery of the secured "spring convolution.

The invention is preferably embodied in a valve which is spring-supported and springguided, features characteristic of the structures of my above mentioned patent and application.

In the accompanying drawings, Figure 1 isgi vertical section of a valve mechanism which embodies one form of the invention, and Fig fiisee plan viewp'f the valve and -spring illustrated'irnfig. 1. F i gl 3 is a view similar tQ FijgJQ', illustrating another means of uniting the valve and spring, and Fig. 4 40 is a. section of a portion of a valve mechanism like that illustrated in Fig. Lbu't embodying the valve and spring uniting means illustrated in Fig. 3.

Referring to the drawings, '2 designates the valve seat which in the form illustrated is multiported at 3, the valve seat being titted in head or wall l of the machine to which it is applied. ,Plate valve 5 is shown formed with'the inner and outer ring pertions 6 and 7 complementary with the valve seat ports, the two ring portions being con-- nected by the webs or bridges 8 which support the segmental valve ports 9. It will be understood, however, that the valve and valve seat may be variously ported, the form here shown being only one of various adaptations. I

In the present invention, as in my above mentioned patent and application, the valve is spring-supported and spring-guided. The

spring 10 as here shown is of fiat or plate form rather than of the spring wire form illustrated in my former patent, the plate form providing greater lateral rigidity. Various means may be employed for fixedly uniting the valve and that portion of the spring which bears thereagainst with such securing means located wholly between those edges of the spring which are parallel with the plane of inovement'of the valve, in the form of spring illustrated those edges being the inner and outer peripheral edges 11 and 11, respectively, of the secured portion 12 of the end convolution of the spring. As shown in Figs. 1 and 2, spring portion 12 is secured to the valve by being welded thereto, the weld extending from the spring extrenr ,ity 13 to approximately the point indicated by the reference numeral 14, the welded portion being tinted or shaded while the tree portion of the spring which terminates in the central ring-like supporting extremity 15 is not shaded. With the parts assembled as in Fig. 1, valve 5 operates between seat 2 and the stop 16, the latter being secured to the seat by bolts 17, the latter also passing through the ring-like spring center 15, thereby clamping the valve-supporting and valve-guiding spring in place.

In the form shown in Figs. 3 and 4, part 12 of the spring which bears on the valve is secured thereto by rivets 18, the secured portion 12 being substantially the same length as the welded portion in the construction first described.

It is characteristic of each of the illustrated forms that the means for securing the spring to the valve is located wholly between or within the longitudinal lines of the spring so that the ports are not obstructednor the movement of the spring and valve interferred with.

I claim:

1. The combination of a blowing enginevalve, tapered valve-actuating coiled spring formed of a relatively thin fiatinetal to resist lateral deflection and having nesting convolutions adapted to lie in the same plan when the spring is fully contracted, a. portion of the larger convolution of the spring adapted to bear flatly orf'the valve, means rigidly securing a portion of the larger convolution to the valve with the secur- 7 111g means located wholly between the inner and outer edges of the secured portion of the spring, and a device to which the smaller end of the spring is secured for rigidly supporting the spring and the valve against lateral deflection without interfering with the tor sional stress to which the sprlng is subjected by the action of the valve.

2. The combination of a blowing engine valve, a tapered valveactuating coiled spring with each convolution relatively thin and flat, a portion of an end convolution of the spring welded to the face of the valve for innnovably uniting that portion of the spring with the valve, and a supporting device to which the opposite end convolution of the spring is rigidly secured, the flat metal of the spring and the connections between the latter and the valve and the support resisting lateral deflection resulting from torsional stress to which the action of the valve subjects the spring.

3. Theeoinbination' of a. valve for blowing engines. etc, a tapered valve-actuating and guiding'coiled spring formed of rela tively thin flat metal which resists lateral de flection and having nesting convolntions, a portion of the length of the spring at one end thereof bearing flatly on the valve and welded thereto, and a support'to which'the opposite end of the spring is secured.

it. The combination of a valve seat, a valve stop rigid with and extending over the seat and separated therefrom by a relatively liarrow space, a valve movable in said space, and a valve actuating and guiding coiled spring located between the valve and stop and at one end rigidly held between the stop and seat and at its opposite end welded to the valve, the spring formed of relatively thin flat metal which resists lateral deflection and having nesting convolutions adapted to lie in the same plane when contracteih In testimony whereof I aliix my signature "in presence of two witnesses.
