14 Claims.

This invention relates to means for transferring liquid from one container to another, the principal purpose of the invention being to provide cooperative instrumentalities, for this purpose, on the two containers, so formed that the receiving container cannot easily be filled except through such instrumentalities.

In Letters Patent of the United States granted to us August 28, 1928, No. 1,682,544, for Combination inflow controlling and fluid discharge means, we have disclosed apparatus for dispensing oil or other liquid commodities in small measured quantities, by means of bottles so constructed as to be refillable conveniently only from a particular source of supply, through connecting means provided for the purpose. The present invention relates particularly to connecting means used in, or suitable for use in that connection or for any analogous purpose, and the present application is, in part, a continuation of the application on which our said patent was granted.

Fig. 12 is a bottom plan view of the receptacle 56 top and pouring spout shown in Fig. 1O.

Fig. 13 is a vertical section through the pump nozzle shown in Figs. 10 and 11.

The invention is illustrated as used in a system of apparatus comprising one or more glass bottles 1, such as are commonly used for dispens- 00 ing lubricating oil at retail. Each bottle is provided with a metaltop 2 providing the usual pouring snout.

For the purpose of refilling the bottle, a pump 4 is connected with a suitable source of supply. 05 The bottle top and the outlet pipe 5 of the pump are provided, respectively, with a filling spout and a nozzle, formed to cooperate with each other and embodying the presentinvention.

As best shown in Figure 2, the spout 3 is the shape of a frustrum of a cone and is fastened permanently to the inside of the top 2 by a screw threaded collar 7 on the reduced inner end portion and has a series of apertures 8 in the faces of the outwardly projecting surface portions.

The nozzle 6 is likewise provided with cone shaped sides 9 apertured at 10 to correspond and cooperate with the apertures 8 in the spout 3. The portion 11 of the nozzle between the inwardly projected cone sides 10 and the tubular sleeve 12 is open to afford a channel directly to the oil source. On the periphery of the cylindrical portion 12 is a means for temporarily retaining the filling spout and receiver while being filled from the nozzle 6. It is here shown as a lug 13 35 notched to engage with an upwardly projecting pin 14 screwed into the filling spout 3. A partial turn is suflicient to bring the lug in contact and to aline the series of holes 8 and 10 to allow filling of the receptacle or bottle 1.

The bottle top 2 is fastened to the receptacle 1 by bending over and crimping the edges 15 under the shoulder on the bottle as shown in Figure 3. In assembly, a cork or other cushion gasket 16 is placed between the top of the bottle and the bottom of the snout 2 to insure a tight joint without injuring the bottle. The top 2 contains a check-valve 1'7, which is hinged at 17a so as to open when the bottle is inverted,.but which prevents refilling through the snout. The 100 top also contains a baflle 18, to prevent tampering with the valve 17, which as best shown in Figure 4, consists of two crossed platespractically hindering any and all attempts to open the valve 17 to" effectively prevent filling of the bottle through 5 the top of the bottle cover 2.

Although the holes 8 are sufiicient in number. to permit the bottle to be filled quickly and easily through the nozzle 6, they are too small, individually, to permit oil to be poured in or introno duced conveniently by any ordinary means. To prevent refilling from an unauthorized source by means of a hose placed over the filling spout, a groove 19 is channeled in the lower surface of the spout, as shown in Fig. 6, so that oil passed through the hose would escape through this groove, to a considerable extent, instead of entering the holes 8.

In the modified form shown in Figures '7, 8 and 9, the receptacle top 2a, is similar in shape to that shown at 2 in Figure 1, and is similarly provided with a filling spout 3a which however is of a difierent shape, more dinicult to fill and easier to construct. This form is of frustro-pyramidal shape the vertical planar sides of which are provided with a series of apertures 8a through which the fiuid enters. Integral with the end or" the conveying pipe 5a which is purposely inclined to allow drainage to the filling source, is the cooperating embracing fiange nozzle 6a which has alined apertures 10a to coact with the holes 8a and convey the oil or other fluid from the conveying pipe to the interior of the bottle or other measuring receptacle.

The nozzle end 6a has a surmounting boss in which is a vertical slot 21 as shown in Figure 9, and the bottle top 2a has a boss 22 above the pyramidal filling spout and through which projects a horizontal pin 23, adapted to enter the a slot 21 in the nozzle end.

The bafiling devices 24 in the pouring snout are different from those shown in Figs. 2 and 3, but need not be described, as they constitute no part of the invention claimed herein.

If it is desired to use the nozzle 6a without filling the receptacle let, for example when it is desired to draw a small quantity of oil into an open receivento prevent Spurting of the liquid, lip baflle 25 hinged at 26 to the boss on the end of the -'nozzle 6a may be turned down from the open position in Figure 7 to the closed position in Figure 9. This will then cause the liquid toflow directly down out of the open end 27 of the nozzle.

When the contents are poured from the bottle the filling spout serves as an eiiective air inlet, but does not readily permit the escape of liquid through the small holes if the bottle is held with the spout on the upper side of the pouring snout.

A still further modified form of connection shown in Figs. 10 to 13, inclusive, comprises a ing shape would operate for the purpose disclosed. The spout communicates, through an opening 91), with the body of the receptacle.

The nozzle 6b is provided with an integral U- shaped hollow head 102) which is adapted to receive the filling spout 3!). Near the top of each of the lateral members 10b of the nozzle is a row of apertures corresponding to and adapted for communication with the apertures 8b in the filling spout. A limit pin 14b limits the distance that the filling spout 322 may be inserted in the 3b in the filling spout, communication will be opened directly from the the interior of the nozzle head to the interior of the receptacle. It is also obvious that the apertures may be variously arranged similar to the tumblers in a tumbler look so that but one combination will fit a designated series of nozzles. In other words, the number, size and location of the apertures may be varied so that but one combination will be operative.

A cover plate 162) fastened to the top of he U-shaped head 1% cooperates with the top of the filling spout 3b and a cam and lever 18b mounted on the head and extending over the cover plate may be rotated to press the cover plate against the top of the spout so that the filling spout is wedged securely between the sidemembers 1% of the nozzle and no leakage will occur. Upon being released, the cam will take the position shown in full lines in Fig. 13 and will allow the filling spout to be released from the filling nozzle.

To prevent dripping of oil from the pump when not in use, the holes 12%) are located as near the top of the nozzle head 102) as possible, and the conduits 20b leading thereto are downwardly inclined so that when the pumping is stopped and the spout 3b removed from the nozzle, the oil in the conduits 2032 will drain back to the pump and will not drip from the openings 12b. The areas of the apertures 82; and 9?; may be regulated to insure adequate flow of oil through the aperture 9?) to drain the filling spout as rapidly as oil is pumped therein through the apertures 8b, and as these apertures are located at the top oi the side walls of the spout, there is no drip when the spout is removed from the pump. g

In order to take care of possible oil drip caused by operation of the pump when no spout is in place, a catch basin 22b is formed under the nozzle head 6?) and is provided with a return conduit 24th which may desirably lead to the receptacle to permit the oil to return thereto. This drip basin 2227 will preferably extend up the inner side of the nozzle to seal the nozzle from dirt and to insure the catching of all the oil which does not actually pass into the receptacle to be filled. j,

The baffles 262) and the check-valve 28b, shown in Figs. 10 and 12, have the same functions as the corresponding parts in the other illustrated embodirnents of the invention.
