BARREL-HEAD.

Specification of Letters Patent.

Patented Feb. 20,1917.

Application led June 18, 1915. Serial No. 34,832.

To all 'whom t may concern.'

Be it known that I, HARTLEY ELLIS, a citizen Vof the United States, and a resident of Cleveland, in the county of Cuyahoga and State ofOhio, have invented certain new and useful Improvements in Barrel-Heads, of which the following is a specification.

My invention relates to improvements in barrel heads, and it consists in the combina# tions, constructions, and arrangements herein described and claimed. Y y l Anobject of my invention is to provide a barrel head which may be removed from the barrel, thereby permitting ready access to the interior.

A further object of my invention is to provide a barrel head vwhich is especially adapted for steel barrels or other receptacles containing liquids, such as paint or varnish, and having means for locking the v head to the barrel and Vfor unlocking it when it is desired to have access to the con-y tents of the barrel.

A further object of my invention is to provide a head for steel barrels which will stand great pressure and yet which may be readily removed and replaced.

Other objects and advantages will appear in the following specification, and the novel features of the device will be particularly vapointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming a part of this application in which- Figure 1 is a sectional view through the head.

Fig. 2 is a plan view. p

Fig. 3 is an enlarged section of a portion of the head.

Fig. 4L is a section through the locking mechanism of the head.

Fig. 5 is a plan view of the part shown in Fig. 4. v

Fig. 6 is a plan view of one of the cam plates. i

Fig. 7 is a perspective view of one of the locking plates.

In carrying out my invention I make use of any suitable body portion. In Fig. 1 I have shown a body portion 1 which is of steel and to which is securedon the upper interior edge, a ring. This ring is preferably welded to the steel body portion 1. The ring consists of a base portion 2 having an annular shoulder 3 and being provided with an annular groove or recess 4,

-of theplate I have shown at 12 and the cam the upper wall of the groove being tapered or beveled as shown at 5. rAs will be lseen from Fie. 3, the beveled wall 5 is carried by a portion 6 which extends inwardly, thisf portion being preferably welded to the member l as stated, and forming with the portion 2 an integral inwardly extending flange provided with a shoulder and a groove. The closure is shown at 7. served that it is concave on th-e outer side.

The edge of the closure is bent laterally as'`V I shown at 7a and is arranged to engage the upper portion of the inner part of the member 2 and to abut the shoulder 3.

The locking ldevice for the closure 7 is best shown in Figs.` 4 to 7 inclusive. It comprises a lower base plate 8, of circular shape, to which is riveted a central disk or plate 9 having a peripheral flange 9x which is raised from the surface of the plate 8 and which is provided with a shoulder Sly, thisshoulder forming'a bearing for a cam plate 10. The latter has four inclined cam surfaces 10a, and as stated is rotatable about the plate 9. This cam plate 10 is riveted or otherwise secured to a larger cam plate 11 which is providedy with four cam slots 11a which follow the contour of the cam surfaces 10EL asshown in Fig. 6. v

. In Fig. `7 I have shown one of the locking members. This consists of a plate which is really the segment of a ring and which has on its inner edge a cam flange.` vThe body flange at 12a. A pin 13 is arranged to eX- tend through the slots 11av in the member 11. Fach of these locking plates 7 is provided with a series of parallel slots 12". Y The central one of these slots lies on a radial line through the center of the lockingdevice as a whole, while the other two are parallel with the central slot. These slots are arranged to receive pins 14 carried by the base 8. n A cover plate 15 is provided which has 109 a downwardly extended peripheral iiange 15a and an innerA downwardly extending fiange 15b. The cover 15, the cam plates 11v and 10, are provided with registering openings 15, 11, and 10c, respectively, for the 195 reception of the fingers 17CL wrench 17.

From the ioreoin' descri )tion of the of a spann er various parts of the device, the operation The 110 thereof may he readily understood. barrel is `filled with paint, oil, gasolene, or other material desired to be shipped, and I the closure '7 is placed in position,a gasket i8 is now placed over the abutting edges 7a and 3 of the closure and the shoulder' respectively, this gasket being of any suitable type but being pfeferal.lifY wicking which has been treated with some material such as pitch to render the same leak-proof. The base plate 8 of the locking mechanism is now laid on the gasket. The locking mechanism beingy in its retracted position, Ythe spanner wrench 17 is inserted inthe alined openings l5", llc, and 10 and the wrench is turned, thus rotating the cam members l() and il about the plate 9 as a center. The plate l() will force the locking Vmember 12 eutwardly owing to the engagement ofthe cam surfaces l0v of tue plate l() with the cam surfaces l2 of the plate rille-beveled surface 12C of the locking member l2, see Fig. 3,V

engages the inclined surface and forces the locking 4member down against the gasket 18. Further movement of the locking member will cause the latter to enter underneath the flange G so as to permanently lock the head in position.

"l ow if the barrel should 'be left out in the sun and be heated up, any pressure of the gases which develop from the inside of the barrel, rwill tend to force the closure 7 outwardly, but being of concave shape it resists this pressure. Moreoven'the edge of the closure is forced tightly against the shoulder 3 and this effectively prevents any further movement of the closure. lt will be noted that the locking plate is positively held by means ofthe flange 6.

Now when it is desired to open the barrel, all that is needed is to insert the spanner wrench and reverse the movement, whereupon vthe plate il in its rotation will draw oh the pin 13, thereby causing the retraction of the locking member l2 and permitting the closure 7 to be removed. It will be observed that the retraction of the locking members is simultaneous, so that the one movement effects the unlocking of the de vice. Y

Sinee'the locking niechaiiiisnr is composed of members which are held together, there are in fact only two separate parts which constitute the barrel head, that lis to say, the closure 7 and the locking mechanism as a whole, so that when the barrel is open these two parts may be placed aside and after the contents of the barrel is used,'they maybe replaced and the empty barrel returned to the point from which it was ori'gi nally shipped.

lt will be seen at once that this device is especially desirable for those liquids such as gasolene, and oils which tend to give off vapors that exet considerable pressure when heated. The head is made in such a way that it will withstand enormous pressure and yet it may be readily removed or replaced.
