E. PIQUEREZ DI SPENS ING DEVICE Filed Dec. 22, 1937 Dec. 6, 1938.

2 Sheets-Sheet l Dec. 6, 1938. E. P|QUEREZ DISPENSING DEVICE Filed Dec. 22, 1937 2 Sheets-Sheet 2 Patented Dec. 6, 1938 l UNITED STATES PATENT OFFICE Application December 22, 1937, Serial No. 181,219 In France January 4, 1937 13 Claims.

The present invention aims at the provision of an apparatus, preferably portable, that will permit any desired quantity of the contents of a flexible package containing a liquid or viscous substance such as oil or grease to be supplied almost instantaneously and without soiling the hands.

According to one form of the invention the apparatus comprises, in combination, an outer casing intended to receive with some clearance a crushable package containing the substance to be supplied; means for permitting outflow from the casing of substance contained therein; means for forming a substantially sealed joint between an inserted package and said casing around said outflow means; a perforating nozzle element, slidably mounted in said casing, adapted to pierce the wall of the package and thereupon to provide communication between the interior of said package and the outflow means of the casing; and means for connecting said casing to a supply of fluid under pressure so that said fluid will enter between the wall of the .casing and the package for the purpose of crushing the latter and discharging its contents.

The means for introducing the supply of compressed fluid under pressure to said casing preferably include a control device whereby the supply of such fluid can be started and stopped as required.

According to one particularly simple constructional embodiment use is made of a hollow perforator fixed to the end of a movable outlet tube that can slide `in a fixed tube on the cover so thatthe perforator can be forced inwardly to pierce the end of a package in the casing. 'I'he movable tube is preferably provided with a return spring whilst at the base of said fixed tube is preferably provided a housing adapted to contain the perforator when at rest. In this case the side of the perforator adjacent to the movable tube on which it is xed is further formed to provide a shoulder or rim, preferably of a diameter substantially equal to that of the housing of the perforator, so that when the perforator rises under the action of its return spring after having pierced the end of the package the said shoulder engages the edge of the opening thus formed and presses it against the rim of the housing in the cover so that leakage of the contents of the package between the fixed tube and the movable tube is prevented.

Further, according to one constructional example, when the package has a circular end, the 55" casing and its cover are fastened together by securing means comprising interengaging elements having inclined or helical surfaces adapted, upon relative rotation of said body and cover, to cause these parts to be clamped tightly together or released as required. The rim at the end of the 5 flexible package may be arranged to be gripped between the body and cover, or a special jointing element may be provided.

The means employed for connecting the casing to a supply of compressed fluid may advantageously comprise two relatively movable, for example, rotatable parts. Thus, there may be a rotatable part forming part of a tubular handle and provided with passages capable of being brought into register with orifices in a fixed part which receives the ferrule of an air or other compressed fiuid pipe.

The annexed drawings illustrate by way of example one constructional embodiment of an apparatus according to the invention. 20

Fig. 1 is a view in vertical section and partly in elevation, the perforator being shown at rest.

Fig. 2 is a section on an enlarged scale of part of the apparatus in the working position.

Fig. 3 is a vertical section of a rotary control valve connection for supplying compressed air.

Fig. 4 is an underneath plan view of the upper member of the valve.

Fig. 5 is a plan View of the lower member of said valve. 30

In the construction illustrated, the apparatus is designed to receive a collapsible package IIJ in the form of a Wallis corner, that is to say, a package having its walls converging from a. circular end or base to a straight ridge parallel with said end or base. The apparatus comprises an outer rigid box or casing, II, of a form appropriate to that of the package IIJ and constructed to receive said package with an appropriate lateral clearance by inserting it from one end and with the bottom Illa of the said package resting in the mouth of the said casing.

The casing, I I, is provided with a cover I2 provided with manipulating wings I2a and lugs I2b which co-operate with helicoidal surfaces on brackets I3 rigid with the casing to enable the cover to be clamped in position or released by a rotary movement and thus form a rapid acting fastening system providing a high.' degree of tightness.

By means of this arrangement the peripheral rim IIlb securing the wall to the bottom of the package IIJ is clamped between the cover I2 and the upper rimof the casing Il. The joint thus formed ensures that the space Il around the package is closed and prevents any communication between this space and the outlet from the apparatus.

Said outlet is constituted by a xed guide in the iorm of a tube I5 integral with the cover and a movable tube I6 able to slide in the tube Il. The tube I5 is rigid at its lower end with a hollow perforator element I1, for example of conical form, whose lateral surface presents orices I3 communicating with the hollow interior and, consequently, with the outlet tube I6.

The side of the perforator element I1 adjacent to the foot of the tube I6 is of greater diameter than said tube and forms with 'respect thereto a shoulder I1a slidably fitting with a minimum of clearance in a chamber I3 formed by a recess in the lower part of the tube I5. A spring 20 is interposed between the extremity of the tube I5 and a flange 2| fixed on the tube I6, so that the shoulder Ila of the perforator I1 is normally held against the inner end of the chamber I 9 and the said perforator is entirely withdrawn into said chamber.

The device for the introduction of compressed fluid to the casing II will now be described. For this purpose the casing II is provided, for example on its side, with a tube 22 on which is mounted a tubular handle 23. Said handle 23 and tube 22 are constructed to form a rotary distributor valve, for which purpose the extremity of the tube 22 is provided with a base member 24 traversed by passages 25, 26, adapted respectively to register with two other passages 21, 28 formed in a member 29 which forms the bottom of the handle 23.

'I'he two opposite faces of the upper and lower members 24 and 29 of the valve are carefully set and are maintained in contact with one another by the action of a spring 30 disposed in a housing 3| in the handle 23 between the bottom of said housing and the rim 24a of the member 24.

The passage 21 in the lower member 28 communicates with a connection 32 of any appropriate type adapted to be joined to a conduit of air or other compressed fluid whilst the passage 28 communicates with the atmosphere by way of a small channel.

-The two operating positions of the handlevalve are fixed by means of a spring finger 34, arranged in the base member 29 and adapted to engage alternatively in two notches 351, 352, in the fixed member 24. When the apparatus is not in use, the finger 34 is engaged in the seating 351 and the passages 26, 28 are in communication, the casing I I being then at atmospheric pressure.

When the apparatus is required for use the package II) is introduced into the casing II and the cover I2 (Fig. l) is applied. 'I'he tube I6 is then pushed in briskly so that the perforator I1 periorates the end Ilia of the package and said tube is let go. In returning under the action of the spring I Il, the perforator engages by its shoulder I1a with the edge 36 of the opening which it has formed in the said end, so that this edge is urged upwardly and caused to bear against the cover around the mouth of the chamber I9 (Fig. 2). The joint thus formed resists to the leakage of the contents of the vpackage between the twotubes I5 and I 6. In order to discharge said contents, the apparatus is connected to a compressed air conduit and the handle 23 turned until the finger 34 engages in the other notch 352,(Fig. 3). In Fig. 3 of the drawings this nger 34 has been shown for convenience in the radial plane of the passages 25, 21 when registered. The compressed air now has access to the interior of the casing II and and, consequently, expulsion of the lubricant through the perforator I1 and tube I6. When the desired quantity has been discharged the discharge is stopped simply by returning the handle 23 to its initial position, whereupon the connection 32 can be uncoupled from the air supply if desired.

It will be appreciated that the apparatus according to the invention will be extremely useful in practice and by virtue of its mobility will be of the greatest value in garages and service stations fcr automobiles, as well as for use in industrial establishments generally where, since there is no loss, it will permit the rapid and economical recharging of all hand greasing apparatus as well as the direct re-charging of greasers of large capacity.

It will be well understood that the invention is not restricted to the constructional embodiment described and illustrated, but includes any variations thereof coming within the scope oi the appended claims.
