3 Claims.

The present invention concerns a new and improved sput, plug and spout assembly for metal barrels and drums.

It is an object of the invention to provide a cheap, strong, sturdy device which is readily assembled.

It is an object of the invention to provide a sput for barrels which may be readily turned or cast and which has a novel means for maintaining itself in a fixed relationship with the metal barrel.

It is an object of the invention to provide a sput having recesses into which the metal of a barrel may be forced so that a rigid connection may be made between the barrel and the sput.

It is an object of the invention to provide a device upon which a spout may be mounted and placed in a dispensing arrangement with a minimum of labor.

container may be regulated.

Further objects and purposes will appear as the present embodiment of the invention is described and discussed.

In the drawings which form a part of the specification, Fig. l is a sectional View of the entire assembly.

Fig. 2 is a perspective view of the barrel sput alone.

Fig. 3 is a fragmentary perspective View somewhat enlarged so that novel means by which the rigid connection between the barrel and sput is obtained may be clearly shown.

Fig. 4 is a perspective view of the plug. Fig. 5 is a bottom view of the plug.

Fig. 6 is a fragmentary sectional view of the plug and sput assembly with the plug in dispensing position.

Fig. 7 is a sectional view along the line '|'l in Fig. 6 clearly showing the arrangement by which the rigid mounting of the sput with respect to the .metal of the barrel or drum is obtained.

Fig. 8 is a fragmentary sectional view of a modified form of sput.

Referring now more specifically to the drawings, like numbers thereon indicate like parts throughout.

The metal In of a barrel or drum is open flanged as at l l to receive a sput l2. Sput I2 is an annular member having an upstanding portion a body member M of greater diameter.

I3 and Body member M has a tapered or conical outer surface l5 to provide a firm seat for spout 16 which is correspondingly tapered as at IT.

The inner part of sput I2 is threaded as at 18 to receive a plug such as l9. Between parts of body M and upstanding portion I3 is an annular recess 20. This annular recess 20 receives the open flanged lip H of metal ill. The bottom of recess 20 is recessed as best shown in Figs. 3 and '7. This is accomplished by means of removing additional portions of metal from certain parts of the bottom of the recess as at 2| and leaving other portions as at 22. The inner portion of the body member M of the sput is provided with a conical bearing surface 23 which will serve as a seat for rounded portion 24 of plug IS. A gasket 25 may be provided if desired. However, the plug l9 and sput I2 may be so accurately made that the seal between rounded portion 24 and the conical surface 23 is complete with a metal to metal contact.

lug I9 is provided with a portion 26 which is of a smaller diameter than rounded portion 24. This portion 26 is threaded and meets with threads l8 of sput l2. Portion 26 is recessed as at 21 in order to lighten the plug and save metal. The opposite side of plug I9 is recessed at 28 to provide a socket for a conventional barrel wrench. This socket 28 is made up of two equal square holes having the same center but rotated fortyfive degrees with respect to each other. This arrangement permits the wrench to fit at every forty-five degree angle interval.

As previously mentioned above the rounded portion 24 bears against the conical surface 23 to form the seal between the plug and the sput. The threads [8 and 26 are not relied upon to form this seal. Passages 29 are provided in plug l9 which communicates with the recess 21 and so to the inner portion of the container and at their other end with the outer portion of the plug beyond the threads I8, 26 but within the seal formed by the contact of rounded portion 24 and conical surface 23. These passages 29 may roughly be of any size desired and it is their purpose to conduct the fluid within the container around the threads is and 26.

Spout I6 is fastened to sput l2 by means of a strip or split ring 3!] which is provided with upstanding lugs 3! which permit its being tightened by means of a bolt or the like whereby spout I6 is firmly fastened to the sput I2.

In assembling, the sput [2 as shown in Fig. 2 is placed upon the open flange I l in the metal ll] of the barrel so that lip ll fits within recess. 20. The head is then placed in, a press which firmly forces the metal of lip II into the bottom of'recess.20 so that portions 32 of lip II are'forced into recess 2I in the bottom of annular 'recess 20. As will be seen from an inspection of Fig. 7 this provides an extremely rigid and strong construction. Since the metal forming upstanding portion I3 of sput I2 is at the same time upset and forced over as at 33, it will be seen that the lip I I is locked into annular recess 20. The upset portion 33 of sput I2 firmly holds the barrel metal III and sput I2 together'while the extrusion of the portions 32 of flanged lip II into the portions 2I of annular recess 20 insures a rigid strong seal between metal III and sput I2 in such a manner that they cannot rotate with respect to each other. The metal of flange I I is deformed and caused to flow into recesses 2I. The flange II however resists the deformation and when clamped in place under the action of upset lip 33 it acts as a compressed spring and yields a very tight joint. The flange II thus performs the double function of preventing rotation of thesput and making a very tight compression joint. This spring action of the distorted flange I I, maintains firm sealing contact between the inner wall of barrel I0 and lip 33 even if theibody of the sput and the outer wall of the barrel III are no longer tightly sealed due'to rough handling having a tendency to pry the sput loose.

When it is desired to dispense from the barrel or drum in relatively small controlled quantities the spout I6 is placed in position onv sput I2 by means of strap 30 and plugIQ is rotated by fltting a wrench in socket 28 and turning. This breaks the seal between rounded portions 24 and conical surface 23. If a gasket is used the seal between it and rounded portion 24 is broken.

'By'meansof channels 29 the fluid within the barrel has constant access to the annular space tended for reshipment.

34 between plug I9 and sput I2. The channels 29 are preferably'three in number and may be circulahelliptical or rectangular in cross section.

They are diagonal with respect to the axis of the plug and are so placed as to weaken it least. By this arrangement the threads are not interrupted in any way which insures longer life for them. This is important in heavy barrels which are im The fluid is of course outside the threads l8. As soon as the seal between portion 24 and surface 23 is broken the I fluid will flow from the container as shown at 35 from the outer wall of the sput.

rangement however removes any necessity of threadinga faucet or the like into the sput. By this means a very considerable economy in dispensing is obtained because leaks and the like are avoided as a tight fit is assured at the factory for shipping purposes.

r Fig. .8 differs from Figs. 1, 2, 3 and 6 solely in the location of upstanding portion I3. An annular channel 36 is provided and forms portion I3 This construction greatly decreases the height of the sput and keeps the assembled sput and plug well below the rolling hoops in the drum. The threaded portion of the sput may be recessed to provide drain age if desired.

In the conventional type of sput and plug now 7 in use the sealing surfaces are perpendicularto the threads. In practice it is difficult and costly to machine the surfaces of the sput and plug at true right angles to the threads. If the tolerance sui'ficient allowance so that the round portion ofthe plug will find a correct sealing position around the complete circumference. The action here is that of the plug grinding a seat in the bevel surface 23 of the sput. .As the contact between the two surfaces gives a sliding wedge effect the me The following combinations are claimed and.
