C aims- 1.

This invention relates to valves; and more par-,- ticularly to a. valve especially adapted to. control the flow of gas from one receptacle. to another;

An object of the: invention is to provide a. simple and compact valve mechanism which will provide for passage of gas in a direction con;- trolled by the will of the operator.

Another object of the. invention is to provide a valve mechanism that is adapted. to be easily and quickly operated; the valves of which are capable of closing tightly so as to control. the flow of gas from one receptacle: to another.

Another object or the invention is to provide. a valve mechanism which, when actuated, will permit gas to pass. from one. receptacle to an-. other and which, when at. rest, will; permit a. passageway from one of the receptacles permit-. ting gas to be exhausted into the outside atmosphere.

Other objects reside in the provision of a strong, durable and eiilcient valve mechanism which is. simple in constructionand relatively inexpensive to manufacture.

These together with. the various ancillary.- ob-. jects of the invention which. will. become ap-.. parent as the following description proceeds, are. attained. by this valvemechanism, a preferred embodiment of which has been illustrated. the accompanying drawings, wherein:

Figure l is a side elevational. View of the. valve mechanism. comprising the present invention;

Figure 2 is a top plan view of the valve mechanism shown in. Figure 1;

Figure 3 is a vertical sectional view of the. valve. mechanism shown in Figurev 1,. in an enlarged scale for greater detail; and

Figure 4 is a vertical sectional view as taken. along line t-i in Figure 3.

With continued reference to the accompanying drawings wherein like reference numerals designate similarparts throughout the various views, I E! generally represents a. casing of a desired shape in which the major portion of the elements. of the valve mechanism are emplaced. Extending through one of the side walls of the casing In is a. cylinder 12 which is in alignment. with a bore i l extending through the rest of the casing and being enlarged as at A plunger it having a tubular portion :3 is inserted in the cylinder 52. The tubular portion 13 has a plurality of annularly spaced apertures such as 26 therein which are adapted to selectively communicate with the atmosphere at the outer end of the. W1- inder 42. A pair of oppositely disposed slots, 22 are formed in the tubular portion I801 the 2 plunger--16 and a pin 26 is secured to the inner wallsof the cylinder [2 and extends through the slot to limit the outward movement oi the plunger l6.

A spring 26 is positioned in the cylinder [2 and biases theplunger It outwardly and the inner end wall 28 of the cylinder l2 inwardly. The cylinder l2 has a recess. therein together with a plurality of spaced apertures 32 extending through its side walls in communication with the recess 31?. The cylinder 1'2 is secured to a disk 34 which is urged by spring 33 to seat upon a valve seatilt secured to the shoulder id formed by the difference in diameter of the bores 54 and F5. The annular ring 38 is. formed from a flexible and compressible material such as rubber and forms an lair-tight seal when used in conjunction with the disk 34. Secured to the disk 34 and extending therefrom is a tubular member ll. which is slidably inserted into a recess Al in the plug. 45 which is threadedly' engaged, as at 43, in; the side Wall adjacent the bore. lb of the casing... The opposed ends of the spring bias the disk 34 and the plug A compressible washer 5B. isinserted between the plug and the casing. In communication with the bore is a bore;52 whichis internally threaded, at for reception of means to supply gas under pressure. In communication with the bore it is up a passage or bore 55 which extends through the externally threaded base 58 of the casing.

As best shown in Figure a cylinder $59 is secured in. threaded engagement with the base 5 8 of thev casing and has a piston 52 therein.

Pivoted by meansof a suitable pin 5 to the casing I0 is a. valve trigger which additionally is pivotally connected by pin 88 to the plunger 16. A suitable handle ll) is secured to the lever portion of the trigger mechanism 5%. As best shown. in Figures 1 and 2, the lever portion of thetrigger mechanism 66. is inserted in a suitable slot in the. head of the plunger i5.

In operation, the initial movement oi the valve trigger 5,6 inwardly causes the escape ports is to be closed while depressing spring The outward travel of. the plunger however, is limited by the retaining pin 25 in the slot 22. Farther inward movement of the urigger will effect movement of the cylinder l2 byengaga ment of the shoulder on the plunger witthe cylinder, thereby causing the solid cylindrical portion 28 of the cylinder to lift the is off the valve seat 33 and to compress spring 35. Gas entering through bore 52 is allowed to pass out of passagelit. Releasing of the trigger 56- first closes the valve comprising the disk 34 and the seat 38, preventing further passage of gas out of the passage 56. The further release of the control trigger 66 allows outer escape port formed by the apertures 20 and [4 to open. Air may now return inward through passage 56 entering inner escape port 32 and passing through the hollow section 30 of the cylinder l2 and through the hollow section I8 of the plunger to exhaust through the outer escape port formed by the apertures l4 and 20. The assembly of the various parts of the valve mechanism is possible because the valve plug 46 is detachably secured to the casing. The valve plug also acts as a bearing through which the valve comprising the disk 34 and the cylinder 4-2 may slide.

It is not intended to limit the use of this valve to any particular device, and many various uses may be found for this invention. Since, from the foregoing, the construction and advantages of this valve mechanism are readily apparent, further description is believed to be unnecessary.

However, since numerous modifications will occur to those skilled in the art after a consideration of the specification and the accompanying drawings, it is not intended to limit the invention to the precise embodiment shown and described, but all suitable modifications may be resorted to which fall within the scope of the appended claims.

Having described the invention, what is claimed as new is:
