12 Claims. (Cl. 220-86 closed container having a dispensing opening, a

pipe leading from the opening to a point adja: cent the bottom of the container, a check valve associated with the inner portion of the pipe to preclude flow through the pipe into the interior of the barrel while providing for fiow from the interior of the barrel out through the pipe, means connecting the pipe with the margin of the dispensing opening, and a locking device for securing the pipe against removal, the locking device being of such character that it is releasable only in a predetermined manner and with the aid of special releasing tools or devices.

One of the principal objects of the present invention is to provide a highly effective type of locking device which is so compactly and closely organized as to occupy a. minimum space and as to be susceptible of economical production from materials and by means of facilities ordinarily available. The locking device in all of its several embodiments positively secures the pipe or conduit against removal by unauthorized persons and yet maybe readily manipulated to release ed out in the appended claims, reference being had-to the accompanying drawings, forming a part of this specification, and in which:

taken on line 44 of Figure 3; V Figure 5 is a fragmentary sectional View, parts being shown-in elevation for the sake of simplicity in illustration showing another type ofjlocking device;

Figure 4 is a view in transverse cross section Figures 6 and 7 are views in horizontal cross section taken on lines 6-6 and. l-' respectively, of Figure 5;

Figure 8 is a fragmentary view partly in side elevation and partly in vertical cross section, the

plane of .the section being designated by line 8-8 in Figure 6; and r Y Figure 9 is a View similar to Figure 5 I showing still another type'of locking device.

Referring to the drawings, and more partic ularly to Figure 1, the numeral l designates the body of a barrel or similar container which is entirely closed except, for the provision of a, single opening 2.- Of course, a suitable vent may be provided, one such being designated by dotted lines at Vin Figure 1. v v A bushing 3 has a reduced inner end 4 inserted in the opening 2. The bushing is flanged asat 5 and the periphery of this flange is welded asat 5 to the top of the container so as to permanentl secure the bushing 31in place.

A vertical pipe or conduit Iv is'provided and has its upper end threaded into a connecting ring 8. A weld 9 may also be provided between the upper end portion of the pipe 1' and the ring 8 to rigidly secure these partstogether.- The periphery of the ring 8 is externally threaded so that it may be threaded into the bushing 3. The

. upper surface of the ring Bis provided with a suitable number of openings In to adapt the ring and its pipe 1 to be applied and removed; under certain conditions, with theaid of a spanner wrench or other similar tool. upper end of the conduit maybe protected by means of a cap II threadedly interconnected with the bushing 3. A gasket I2 is usually pro- The ring 8 and vided between the flange of the cap II and the upper end of the bushing so that when. thecap is tightened up it will provide a sealed closure. 7

slightly spaced from the bottom of the barrel.

For this purpose foot pieces [9 may be integrally formed with or suitably secured to the lower end of the valve casing and welded as at 29 to the barrel bottom. The lower end of the valve casing is provided with an opening 2| and around the inner margin of the opening with a downwardly flaring valve seat 22. A valve 23 coacts with the valve seat 22 and when engaged with the seat as shown in Figure 1 closes the opening2l.

from its seat.

Means is provided for locking the connecting sleeve I5 to the valve casing and in this form of the invention comprises locking balls 25 similar to ball bearings and accommodated in transverse openings 26 provided in the reduced lower end I! of the connecting sleeve. The openings 26 are so shaped and dimensioned as to limit the distance at which the balls may be projected outwardly therethrough but they do allow sufiicient projection of the balls to enable them to have locking engagement with the tapered inner surface 2'! of the upper end of the valve casing.

For forcing the balls 25 into locking engagement with the tapered surface 21 of the valve casing an expanding bushing 28 is provided. The

' upper portion of the outer periphery of this bushing '28 is threadedly interconnected with the sleeve l5 as indicated at 29. Below thisthreaded portion 29 .the exterior or outer periphery of the bushing 28 is smoothed but is provided with an inclined surface 30 which, as the bushing is threaded down into the sleeve, acts on the balls 25 to force them out to the position shown in Figure 1. In this position axial movement of the pipe I and its connecting sleeve 15 relative to the valve casing I8 is positively limited. Hence, the ring 8 may not be unthreaded from the bushing 4 and the pipe 1 may not be removed. The upper end of the bushing 28 is provided with slots 3| designed to coact with a special tool in order to provide for the manipulation or turning of the bushing in either direction by authorized persons.

Sucha tool is shown in Figures 3 and 4 and consists of an elongated shank 35 provided with a cross handle 36 at its upper end and with laterally extending keys 3'! adjacent its lower end designed to interfit with the slots 3 i. Of course, it is to be understood that these keys 3'! and the slots 3| may be of any special shape or configuration.

In this embodiment of the invention when the barrel is full of oil-the cap Il may be removed and any appropriate type of pump maybe conneoted up with the bushing 3 and conduit 1 to dispense the oil from the barrel. However, any

down-flow of oil through the pipe 1 back into the barrel is prevented by the check valve 23. Access to this check valve or removal of the pipe 1 1s efiectively precluded except by persons having knowledge of the special way in which the device is constructed and equipped with the tool such as the tool shown in Figures 3 and 4. By

inserting the tool down through the conduit 1 and engaging its keys 3! with the slots 3|, the ex- Stoppins 24 limit the movement of the valve 23 away panding bushing 28 may be backed up sufliciently to allow the balls 25 to move back against the reduced lower end 28 of the bushing. When the expanding bushing 28 is backed up so that the reduced portion 28' is in alinement with the balls then there is no resistance holding the balls in position and backing out the connecting ring 8 permits the balls to move axially inwardly by reason of the increasing pressure exerted by the inclined surfaces 21 of valve body I3. With the balls in their released position, that is, out of engagement with the inwardly sloping surface 2! of the valve casing, a wrench may be applied to the ring 8 to remove the ring together with the conduit 1, connecting sleeve I5 and the locking device. The barrel may then be conveniently refilled.

The form of the invention shown in Figures 5 to 8, inclusive, is identical with that above de scribed except that a differently constructed locking'arrangement is provided. As in the other embodiment of the invention the-conduit 1, which is connected at its upper end to the barrel ,as

before is welded as at [6 to a connecting sleeve designated at 40. The connecting sleeve has a reduced lower portion 4| fitted in the upper end of the valve casing l8. Transverse openings 26 are provided in this reduced portion of the connecting sleeve to accommodate locking balls 25 as before. However, these lockingballs 25instead of coacting with an inwardly sloping, orineluded surface on the valve casing are adapted to be seated in vertical grooves 42 provided on the inside of thevalve casing, and when so seated prevent turning of the connecting sleeve 40 and consequently the conduit 1. Moreover, in this form of the invention a different type of structure is provided for moving the balls .to locking positionrand providing for their return to released position. I

A flanged and apertured supporting plate 43 is secured in the lower end of the connecting sleeve by means of set screws 44. An oscillating cam 45 is supported on this plate 43 and is con fined to its oscillating movement by the plate and I by means of an internal shoulder 46 formed on the connecting sleeve. This cam is also apertured so that the liquid can freely flow through the cam and the mounting plate. The cam has curved or inclined surfaces 41 designed to wipe against the balls 25 and force these balls out wardly until they ride on the high points 49 of the cam, in which position the balls will be projected into the grooves 42 and the parts locked into position. Transverse slots 50 are provided in the upper surface of the cam so that a tool such as shown in Figure 3 may be employed to rotate the cam. In order to releasably secure the cam in position to maintain the balls projected into locking position or inposition where the balls are permitted to fall back to released position by gravity a ball projected detent 5i is provided in the mounting plate 43 and is engageable with recesses 52 and 53 provided on the 'undersuriace of the cam 45. The extenttowhich the cam i'nay be oscillated in either directioniis positively limited by means of a stop pin 54 fixed tothe'ca m a nd projecting down into an arcuate groove 55"pro' vided in the mounting plate.

In Figure 9 there is illustrated still another type of locking device which may be employed for securing the connecting sleeve at the lower end of the pipe I and consequently also the pipe 1 against rotation. In Figure 9 the connecting sleeve is designated at 56 and is provided in its "of the subjoined claims.

by means of a spring63, the spring being interposed between the inturned annular flangetll provided at the outer end of the-bolt'housing and a shoulder presented by; the guide portion 65 of the bolt. The extent to which the bolt is projected inwardly by the spring is limited bythe engagement-"of an integral head or collar 62 provided on the bolt with the inturned flange. The lower end of the connecting sleeve is beveled as at 61 so that when the sleeveis introduced into the valve casing this beveled end 61 will cooperate with the beveled'edge 68 of the bolt to push the bolt back until one of the openings 58 comes into alinement therewith-whereupon the'spring 63 will thrust the inner end --of 'the bolt into the alined opening 58 and the deducing a special tool down through the pipe i and operating it to thrust the bolt 'outwardly out of theopening 58 in which it is engaged, thereupon the pipe I may be removed; as in the other embodiments of the invention. The special tool may be identical with-that shown and'describedin the Brushe application above referred to and its parts are shown in dotted lines'' in Figure 9 and designated at-22 f23' and 25% -While we have shown and described *sev'eral constructions in which the invention may be; advantageously embodied, it is'to be understood that these constructions havebeen'selected merely for the purposeof illustration or example, and that various changes in the size,- shapeand arrangement of the'parts may-bema'dewithout departing from the-spirit of the invention or the scope The invention claimed is:
