The top ofwthexreceptacle is closed, or open, as may` be preferred, and the material fed into it inany convenient manner.

i. The receptacle comprises' adetachable tip 2l, through which passes the outlet 19 asshown inr `the drawings. This tip is composedfof rigid.material,preferably of hardenednietal `and comprises, `for a purpose hereafter described, :a apart, or faceplate, having a substantially plane downwardly presented surface 21' extending annularly, and radially icutwardly, from and lcompletelysurrounding said outlet, and has also a downwardly extending tubular flange portion 2lH having `an. angular edge, 21', con'- centric with, and closely surrounding' the path of the outlet 19. The inner surface of the iiange constitutes a part .of the inner surface of the outlet(see Figs. 2 and 3).

Underneath the. outlet 19 I 'provide a movable,` a. 6. vertically` reciprocable, can support, 29, (Fig. 1)', which` comprises fa. leg 29* slidably mounted ofthe framed?. ApinQQT, carried bythe leg, isheld-slidably in a lslot 32 located in to,the.,frame. u i

This. `punch isfreciprocated by aid'of allink, or

rod e9,Y slidablysupported in guides 50, `50',-V carried Aby theframe, andicarrying a roller 51,."coactingwith acam 52', carried by the i in a :stationary part' onefarmiofa rock-lewerlBZ, pivoted as at 32" Y adjustably rotatable therein by aid of a thereby carried arm 54, carrying a roller 54', with which coperates a rotary cam 55, carried by the shaft 30, and provided with a projection 55', and shaped and timed to cause the'valve to temporarily assume, and to maintain while required, the position shown inFig. 3. The normal position of this valve is that shown in Fig. 2, and it is returned thereto and held therein by a retractile spring 56, vconnecting the arm 54 with the frame F. The valve 53, is rotatably mounted` in a stationary cylindrical'shell or seat 57 ,carried by the frame Fk to which it is joined by the union 57. An expansile spring 58, bears against the union and the valve to keep the latter properly seated. The valve 53,*comprises a stem 53V containing, as does the valve, a concentric bore, or air duct 53, which is connected by laid of `a rubber hosev59, or other unrigid connection, with any preferred air-exhausting appara- I tus (not shown).V

The lvalve 53, contains a by-pass for the material, z'. e. an eccentric transverse bore 59, whichcommunicates with the outlet 19 when the yvalve is in its Fig.,2. Y

The valve also contains a radial bore, or channel 60, communicating with, its concentric bore, or air duct, 53" and which also communicates with a lateral enlargement, 19', of the outlet 19 ,when the valve has been oscillated by the cam 55 to the position shown in Fig. 3.

Operation: The valve and the punch being in the positions shown-in Fig. 2, and the can suitably positioned on the then depressed support 29, so that the opening, or top, of the can is concentric with the outlet 19 a normal position shown in Vsingle rotation kof the shaft 30, serves to -force the'can up against the tip 21, thereby causing vthe punch 48,'to puncture the head, or to enlarge a previously made opening therein. VThis results in distortingy the sheetmetal and producing an air-tight joint betweenit'and the receptacle 19, as will be apparent and isvalso more fully described in my said Patent No. 1,373,275. The punch is then: raised sufiiciently for it to clear the valve *53,V whereupon the latter is turned into the position shown in Fig.V 3 and air .exhausted Jfrom the. can' through the valve. 1 The punch-bearing member is then completely withdrawn from the outlet 19', as indicated in Fig. 1, and the valve is then returned toits position shown in Fig.- 2, thereby causing the by-pass to communicate withV the receptacle and with the can through the outlet, and the material is permitted to flow' by gravity and atmospheric pressure from the receptacle into the-exhausted can. The

iiow is stopped by again lowering the punch v into the outlet19y as shown in Fig. 3, and the G5 valve v53 is oscillated back to its normal position closing said outlet. The filled can is then lowered and removed and the cycle indefinitely repeated.

It will be understood that, in usual practice, the heads of the cans contain a relatively small central opening, or aperture, of usually not to exceed one thirty-second of an inch in diameter, such opening being illustrated in Fig. 4. But such opening is, although preferable, not essential, the operative end 48', of my punch-bearing member 48 being competent to puncture the head, as Well as to enlarge such opening,-the cross sectional diameter of the punch in this instance being say about one-sixteenth of an inch.

The construction and operation are such as to result in the proper exhausting and charging of a can by a comparatively unskilled operator and through a relatively minute opening more expeditiously, economically, hygienically than heretofore.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is the following, viz

l.- In apparatus for charging a fiowing material into a container, a receptacle for the material having adjacent its bottom a downwardly delivering outlet; a reci rocable valve member within said reeeptacle coperating with said outlet; an oscillatory valve below said receptacle also eoperating with said outlet, and containing an air-duct and also a by-pass for the material, and means to oscillate said last mentioned valve and thereby bring said air-duct and said by-pass alternatively into communication with said outlet.' Y

-2. In apparatus for charging a flowing material into a container', a receptable for the material having adjacent its bottom a downwardly delivering outlet; within said receptacle a movable valve member coperatable with said opening to close it; and a spindle valve disposed and oseillatable transversely of said outlet and containing an airduct and also a by-pass for the material, said by-pass and air-duct being alternately communicable with said outlet according to the oscillation of said spindle valve.

3. In apparatus for charging a owing material into a can, a receptacle for the material having adjacent its bottom a downwardly extended delivery outlet;` a valve in said outlet movable therein and containing a by-pass for the material and an air-duct; a punch bearing member reciprocable within said outlet, said by-pass, and said can; means to turn the valve so that the by-pass communicates with the receptacle and the can, and alternately so that the air-duct communicates with the can through a part of said outlet; and means to reciprocate the punch-bearing member while the by-pass and outlet are in communication.

With said can through said outlet according A to the positon'nto which said spindle valve is rotated; and means to reciprocate the punch-bearing member While `tlne bypass and outlet are in communication.

5. In apparatus for charging a flowing material into a can, a receptacle for the material 'having adjacent its bottom a down- Wardly extended outlet; a spindle valve dis* posed and oscillatable transversely of said outlet and containing an air-duct and also Y a by-pass for the material, said by-pass and air-duct being alternately communicable with said outlet according to the oscillation of said spindle valve; and a punch-bearingmember advanceable from said receptacle into the can when said outlet and bypass are in communication.
