valve; h a ,c I Inthe drawings, thedispensing device is-shown as a drum 1 having a bottom wall 2 -provided:

- with a sump 3 receiving-the lower end-of a well 4.

The end of the well-4 isslightly lspacedfrom the,

bottom of the sump-3to allow liquid to be drawn upwardly in the well 'i by means of the pump mechanism connected to the-head '6 of the drum.

- The lower end of the-well 4 may be provided with suitable braces '7 to maintain the well in position orthe braces can be omitted if desired No particular invention isinvolved in the provision of thefsump 3 or the supporting braces 7 as thisconstruction is common in the art The well-4 extends upwardly through the tank 1 and at its'upper end receives a cylindrical member8 shaped to for-maseat for a check valve 9. The check valve 9 is reciprocable toward and 3 from a guard plate 10 forming part of a cage 11 horizontal section; taken on the;

(see; Figure 5). This cageli is secured in a casing 12 suitably shaped for connection to the member-amid is provided at its upper end with a recess 13; in which is seated an; annular nut 14 screwthreaded into a bung holemember 15. A spring lfi ginterposed between the valve 9 and the guard-10 serves to keep the valve 9 normally closed and is sufficientlystrong to prevent the flow f liquid from the container 1 during the handling-and shipment thereof. The operation of this check valve mechanism will be apparent from'inspection ;of;the drawings. I

The upper :endof the bung member 15 terminates'in an outwardly directed flange 17 which is providedwith vent-18.-- The flange 17 its periphery securely gripped-in a recess 19 formed inthevtop wall 6 of the drum or container 1. The: overhanging recess part of the head 6 is slightly spacedebovethe flange 17 inorder to permita flow-of atmospheric air through the central; opening -20 of the recess part 19 of the head 6.

'Ihe-upper'endof-this well and check valve mechanism is-securely braced to the side wall or head 01 1113 tank, as-shown in Figure 1. To effect this bracing, the bung-member 15 has a sleeve 21 suitablysecured thereto and this sleeve has a flange 22 extending outwardly from the lower end 'Fthereof, -Theflange 22 is provided with apertures 23' which receive the hook ends 24 of any desired of bracing members 25 extending radially toward the wall of the container and suitably. secured thereto. It is immaterial whether these-reinforcing strips are secured either to the-head of the drum-or to the wall thereof; they may be rounded over into the chimeof thedrum-i; The-invention isonly concerned with thereinforeing otthis particular part of theqmechan ismfi and-=not with any particular means for efiecting the reinforcement.

- The-pump P comprises coupling members 26 and--27 adapted toconnectthe pump to the head 6 so'thatthe; pump can berotated' about the axis of thev well 4'to move the spout 28 of the pump overany desired-part of the head'6. As shown particularly in Figure of the drawings, the coupling member 26 is externally screwthreaded atits lower-end to be received in the internally screwthreaded bung :member 15. The upper end of the memben'ZS :i-sextended outwardly to :form afiangez 29 l The member 26, between the ends thereof, gisprovided with an annular projection Bil-having a freesliding fit in the-cylindrical bore 371 of thejcou-pl-ingmember 27. The diameter of theaprojectiontfl is less-than the diameter of the flange 29; andgrthisiiange 29 is mounted to slidein a cylindrical bore Biiwhich is larger than the; bore-31 and co axial therewith. The lower part of the bore 32 is beveled inwardly to form a sloping shoulder 33 having a gasket 34 seated The upper end of the member 27 above the bore 32 is outwardly beveled and expanded to form a flange 39 provided with a seat 40 for a gasket 41. The flange 39 is provided with radially extending lugs 42 having apertures 43 adapted to receive bolts fordetachably securing thecorrespondingly shaped base 44 of the pump P to the said flange. The lower reduced part "of the coupling 27 is externally screwthreaded to receive a lock nut 45 provided with radially extending handles 46 and 47 to facilitate the manual operation of the said lock nut. 1

The annular projection 30 has a lug '48 extending upwardly therefrom and parallel to the axis of the bore 35. This lug 48 is arranged to contact with a pin 49 projecting radially through the wall of the coupling member 27 at the upper end of the screwthreaded part thereof. The pin 49 is held in position by a' wire '50 which extends around the said screwthreaded part and has its other end provided with a projection 51 extending into a vent aperture 52. The aperture 52 extends radially through the reduced part of the coupling 27 and into the-space between the bore 31 and the outer periphery of the coupling member 27. r i

As previously stated, the projection 30 is mounted with free sliding fit in the bore 31; and the slight space between the projection'30 and the bore 31 is suflicient to permit-the air to pass through the vent aperture 52 along side the periphery of the member 26 and through the opening 20 to the vents 18 formed in the flange of the check valve mechanism secured to the head 6 of the drum. It will be apparent from consideration of Figure 2 of the drawings that the check valve within the drum really constitutes a check valve for the pump. This arrangement is designed to serve as a protective means to prevent fraudulent use of the container. The manufacturer of the liquid provides the container properly identified by his trade-marks or advertising matter, and also provides a similarly identified pump. The purpose of this is to prevent the useof that particular kind of pump with a" container in which an unscrupulous dealer may have'removed or broken off the check valve mechanism within the container. Since this check valve mechanism operates as an only check valve for the pump;- and since the pump proper has no check valve capable ofseating on the bevel part 36' of the swivel base, it is obvious that destruction of the check valve mechanism within the container would render the pump mechanism itself useless.

The lug 48 is provided so that when the coupling member 26 is raised in the member 27 the coupling member 26 may be rotated merely by rotating the member 27. After the member 26 is properly seated its flange 29 will be properly seated against the gasket-34m secure an air tight fit between the two coupling members.

When this member 26 is seated, the pin 29 will central disbe raised above the lug 48 so that the member 27 can be freely rotated on the member 26 and slid up and downthereon. In order to maintain the proper fit between the members 26 and 27, it

is, necessary to rotate the lock nut 45. It will be apparent that the lower edge of the lock nut rests on the top 6 of the drum and that rotation of the lock nut will press the beveled shoulder 33 lot the member 27 hard up against the gasket 34.

Whenever it is desired to rotate the member 27 and the pump carried thereby, it is obviously only necessaryto slacken up slightly on the lock nut 35 and rotate the'member 27 and lock nut together; and, when the spout of the pump is in desired position, to operate the lock nut by the handles 46 and 47 to lockthe coupling member 27 in the desired position on the drum.

While I have described my-invention as em bodied in concrete form and as operatingina specific maner in accordance with the provisions of the patent statutes, it should be understood that I do not limit my'invention thereto, since various modifications thereof will suggest themselves to those skilled in the art without departing from the spirit of my invention, the scope of which is set forth in the annexed claims.
