VALVE Everell C. Weiiienbach, Buffalo, N. Y., assignor to Cass Products Company, Buffalo, N. Y., a partnership Application February 5, 1947, Serial No. 726,492

3 Claims.

This invention relates to a valve which is more particularly intended for iilling small mouthed dispensing containers, such as bottles, cans and carboys, with free flowing liquid from supply or storage drums, tanks or the like which hold the liquid in large quantities.

One of the objects of this invention is to provide a valve for this purpose in which the several parts can be easily disassembled and reassembled so that the same are accessible for thorough inspection and cleaning without the use of wrenches or similar tools.

Another object of this invention is to provide a valve which permits of cutting oii the flow instantly without drip and permits containers to be lled without spillage or waste.

A further object of this invention is to permit of using a wide range of sizes f outlet nozzles and provide simple and eiiicient means whereby a quick change in the size of the outlet nozzles may be effected.

This valve may be constructed of various metals to suit the particular application and the same may be operated either by hand or foot as best suits the specic installation.

In the accompanying drawings:

Fig. 1 is a side elevation of a valve embodying this invention.

Fig. 2 is a vertical longitudinal section of the same.

Fig. 3 is a fragmentary vertical transverse section of the same taken on line 3 3, Fig. 2.

Fig. 4 is a horizontal section thereof taken on line 4 4, Fig. 2.

Fig. 5 is an exploded side view of the several parts of the valve constructed in accordance with this invention.

Fig, 6 is a perspective of the yoke forming part of the means for detachably securing the nozzle and cap of the valve to the lower and upper ends of the housing or body of the same.

In the following description the same reference numerals indicate the same parts in the several figures of the drawings.

The numeral I0 represents the housing or hollow body of the Valve which is provided on its rear side with an inlet II for the liquid which is to be transferred. This housing is also provided at its lower side or end with a lower cylindrical opening I2 and at its upper side or end with an upper cylindrical opening I3'. The inlet I I is formed in a tubular neck I4 which is adapted to be attached to the outlet of a large storage or supply drum, tank or the like by an external screw thread I5 or other suitable means. The

lower and upper openings I2 and I3 are both of cylindrical form and arranged axially in line.

The numeral I6 represents a discharge nozzle whereby the liquid entering the housing through the inlet thereof is discharged downwardly into a bottle, can or other dispensing container or re ceptacle which is to receive the liquid, This nozzle is provided at itsq upper end with a cylindrical neck I 'l which engages by a slip t with the bore of the lower opening I2 and at its side this plug is provided with a downwardly tapering conical surface I8. By Virtue of this conical surface I3, the nozzle is adapted, if desired, to be inserted into the mouth or iilling opening of the container which is intended to receive the liquid so that no liquid will be spilled during this transfer operation. The upward movement of the delivery nozzle on the housing is limited by an external flange I9 formed around the central part of the nozzle and engaging with the lower end of the housing around the opening l2 thereof, as best shown in Fig. 2.

The upper opening i3 in the housing is normally closed by means of a cap or head which preferably comprises a disk 2@ provided on its underside with a cylindrical flange 2i engaging with a slip t in the opening is of the housing and also provided with an external stop Flange 22 which engages with the upper side of the housing and limits the downward movement of this cap thereon.

Means are provided for securing the nozzle and cap to the housing so that these parts can be quickly assembled and also separated for inspection and cleaning and also for per1nittin T of easily changing the nozzle from one size to another when it is desired to utilize this iilling valve for delivering the fluid into containers having diiferent sizes oi mouths or inlets.

Although this may be accomplished by various means, those shown in the drawings are preferred and constructed as follows:

The numeral 23 represents two upright side bars of a yoke spaced transversely from each other, a lower cross piece 25! which connects the lower ends of these bars and has the form of a ring or eye and an upper cross piece 25 which connects the upper ends of these bars and is provided centrally with a threaded opening 25. In the assembled position of the parts of the valve, the side bars 23 are arranged on diametrically opposite outer sides of the housing, the eye or ring 25 engages with the under side of the flange I9 of the nozzle and the upper cross piece 25 extends over the upper end of a tubular eX tension 2l which projects upwardly from the central part of the disk 20 of the cap.

The numeral 28 represents a clamping screw which works in the threaded opening 26 of the yoke and bears at its lower end against the upper end of the extension 21 and is provided at its upper end with a knurled button or knob 29 whereby the same may be turned.

Upon tightening the screw 2S when the parts are assembled, the yoke is raised relative to the housing and thereby causes the ring or eye 24 to press upwardly against the ilange le and form a tight joint between the nozzle and the lower end of the housing, and at the same time the flange 22 is pressed downwardly against the upper end of the housing so as to form a tight joint between the latter and the cap.

When access is desired to the interior of the housing for inspection, cleaning and repairing the screw 28 is loosened sufficiently lto permit the pointed lower end 3s of the same to be disengaged from the notch Si at the upper end of the cap and thereafter the yoke may be completely detached from the housing, nozzle and cap.

Opening and closing of the port in the nozzle is effected by closure means which preferably consist of a downwardly tapering conical valve seat 32 formed in the bore of the nozzle I6 and a downwardly tapering'valve plug 33 arranged within the nozzle and movable vertically toward and from this seat. When the plug is raised the port or passage through the nozzle is opened and permits the liquid to ow from the drum or tank through the housing and nozzle into the bottle or container which is adapted to receive the same, but when the valve plug is lowered so that its conical face engages the seat of the nozzle, the flow of liquid is completely shut off and no liquid will drip from the nozzle, thereby permitting the transfer of liquid to be effected without waste.

The preferred means for operating the valve plug and holding the same in its closed position are constructed as follows:

The numeral 34 represents an upright valve stem which has its central part arranged within the housing and its lower end connected with a valve plug and its upper end guided on the cap. The connection between the lower end of the valve stem and the valve plug is preferably of such character that the plug may be readily attached to and detached from the stem in order to permit valve plugs of different sizes to be used in connection with corresponding sizes of nozzles for the purpose of rendering this valve suitable for filling containers having different sizes of inlet mouths or filling openings.

As best shown in Figs. 2 and 5, the means for thus detachably connecting the valve plug with the valve stem comprise a coupling shank 35 projecting upwardly from the upper end of the valve plug 33, a socket 35 formed in the lower end of the valve stem and adapted to receive this shank and a coupling pin 3l extending transversely through corresponding openings in said shank and socket.

In order to confine the coupling pin 3l. in the coupling openings of the plug shank and valve stem, this pin is of such length that when the same is in use, its opposite ends terminate within the periphery of the valve stem and a retaining sleeve 38 is employed which surrounds the lower part of the valve stem and is sliolable lengthwisev thereon into. and out of a position in which this sleeve extends across the opposite ends of the coupling pin. When this sleeve is in its lowest position its lower end rests upon the upper end of the valve plug and the central part of this sleeve extends across the opposite ends of the coupling pin, as shown in Fig. 2, thereby preventing this pin from becoming displaced when operating the Valve. Whenever it is desired to remove the valve plug from the valve stem and replace the same by one of a different size, the retaining sleeve 33 is moved upwardly on the valve stem a sufficient extent to uncover the coupling pin. Thereafter this pin may be pushed out of the coupling openings in the shank of the valve plug and the socket portion of the valve stem, thereby releasing the valve plug and permitting the same to be detached from its stem and replaced by another one of the desired size. After such change has been effected, the respective valve plug may be secured to the valve stem by reinserting the coupling pin through the coupling openings of the plug and then lowering the retaining sleeve so as to confine the pin in the coupling openings.

These means for detachably connecting the valve plug with the valve stern are very simple and not liable to get out of order and they also permit of effecting an interchange of valve plugs easily, expeditiously and economically.

During its vertical movements into and out of its closed position the valve plug and its stem are guided by means of a vertical guide-way Se, preferably of cylindrical form, extending upwardly from the under side of the cap into the extension 2l thereof. The valve plug is yieldingly held in its lowered position, so that its conical face engages rmly with the conical seat of the nozzle and prevents leakage or dripping, by spring means consisting preferably of a helical spring 4t arranged within the socket 39 of the cap extension 2'! and a pocket di in the upper end of the valve stem and bearing with its lower and upper ends respectively against the bottom of this pocket and the bottom of this guide-way.

Various means will be employed for lifting the valve plug intoA an open position to permit flow of uid through the valve housing into the container but those which are shown in the drawings are preferred and constructed as follows:

The numeral 42 represents an annular groove formed circumferentially on the. periphery of the central part of the valve stem and providing upper and lower shoulders 43, 44 thereon. ,The numeral 45 represents two arms of a fork which project into the groove AZ on opposite sides of the axis of the valve stem and adapted to engage with the upper and lower shoulders 43 and 45 upon rocking this fork. For this purpose the hub it of this fork is. secured by means of a. pin Ill to the inner part of a rocky shaft 48 which extends across the interior of the housing and has its opposite ends projecting through and journaled in bearings 49 on the adjacent side parts Aof the housing. Leakagev through these. bearingsV from the interior to the exterior of the housing is prevented by means of stuffing boxes 50 of any suitable construction. Turning of the rock shaft for the purpose of raising the valve plug 33 from the seat 3,2 of the delivery nozzle is preferably effected by means of a rock arm or handle 5i which is secured to one of the outer ends of the rock shaft and actuated either by hand or by foot in any suitable manner. Upon turning the rock shaft in the proper direction the fork 4,5, by engaging with the upper shoulder 43 of the valve stem, will cause the valve stem to be raised and the valve plug to be opened. During this movement, the spring 40 will be compressed but when the valve stern is released the spring 40 will automatically lower the stem and valve plug and hold the latter in its closed position.

In the preferred construction the upper opening i3 of the housing is made wider than the lower opening l2 thereof and thus provide ample room through which the fork may be introduced into the housing and attached to the rock shaft.

It will now be apparent that a valve constructed in accordance with this invention accomplishes the advantages heretofore enumerated and that means employed are simple in construction, efcient in operation and capable of being produced at relatively low cost.
