INVENTOR- LEO G. PECK ATTORN EY United States Patent PUMP ADAPTER FOR LIQUID CONTAINERS Leo G. Peck, Ladue, Mo., assignor to Pecks Products Company, St. Louis, Mo., a corporation of Missouri Application October 28, 1955, Serial No. 543,396
4 Claims. (Cl. 222-382) This invention relates in particular to a certain new and useful invention in devices for mounting a pump upon a liquid container to facilitate measured dispensing of its contents.
Heretofore, the transfer of liquids from drums or metal barrels has posed a problem in many industries. In such fields as cosmetics, soaps and detergents, insecticides and numerous others, the user will in many instances merely repackage the drum contents in small containers for individual use. In view of the unwieldy weight and size of such drums, which, when full, may weigh several hundreds of pounds, the direct transfer of liquid therefrom to such individual containers has not been adequately solved. customarily, the drum contents have been discharged either by means of a directly attached faucet or tilting of the drum to an intermediate receptacle, which can be conveniently handled and is, in turn, emptied into a dispensing unit forming a part of an assembly or filling line. Efiorts have also been made to connect the drum by a suitable pipe to a remotely located assembly-line dispenser, with a pump being connected in the line to effect fluid flow.
None of the expedients above mentioned have provided the efiiciency and economy, both in material and labor, necessary in low cost production.
Therefore, it is an object of the present invention to provide a unit to be mounted upon large quantity liquid containers which will accommodate a pump for dispensing measured amounts whereby the container contents may be transferred directly to an ultimate receptacle.
It is another object of the present invention to provide a unit for mounting pumps lJJPOIl liquid containers, as drums, which will adapt the drum for immediate incorporation in an assembly or filling line.
A further object of the present invention is to provide a unit of the type stated which may be economically manufactured, which is reliable and durable in use, and which is easily and elfeetively utilized.
These and other detailed objects are obtained by the structures illustrated in the accompanying drawing, in which- Figure 1 is a side view, partially cut away, of a drum, being connected to a pump by an adapter mounted thereon; said adapter being constructed in accordance with and embodying the present invention.
Figure 2 is a perspective view of the adapter.
Referring now by reference characters to the drawing, A designates a metal drum or barrel, such as is commonly utilized in industry for transporting liquid material, as oil, gasoline, liquid chemicals, and similar products. Drum A does not form a part of the invention, but is shown as exemplary of industrial drums with which a pump adapter B may be used. Said drum A comprises a cylindrical side wall 1 with reinforcing ridges 2, a bottom wall 3, and a head or top wall 4 having a threaded opening or more commonly called bung 5, within which is normally engaged a threaded closure plug (not shown). Provided for engagement within bung 5 is a pump adapter B, which may be cast of any suitable metal or fabricated 2,818,201 Patented Dec. 31, 1957 ICC from thermosetting plastic or other non-metallic materials for producing a rigid structure. Adapter B comprises an elongated tubular body or casing 6, the normally upper end of which is externally threaded, as at 7. At its other, or normally lower, end tubular body 6 is diametrally increased to form a relatively short base 8 which is externally threaded, as at 9, for engagement with the threading of bung 5 for mounting adapter B securely upon drum A with the tubular body 6 extending upwardly from top wall or drum head 4.
The upper threaded end 7 of adapter B is of appropriate outside diameter for accommodating an internally threaded cap or fitting 10 of a well-known type of measured-quantity dispensing pump C, made preferably of plastic, which includes .a dispensing spout 11, a piston having a finger grip 12 formed at its upper end, a chamber 13 of predetermined volume with the lower end thereof in communication with a rigid pipe or tube 14 of such length as to project downwardly below the lower end of adapter B and top wall 4 of drum A when pump C is mounted on adapter B. Attached to the end of pipe 14 is a length of flexible tubing or hose 15 which extends to the bottom of drum A to assure withdrawal of all liquid therefrom.
In actual practice, by use of the present invention, drum A may be situated at any convenient point such as within an assembly line where small individual containers are either being filled with the liquid in the drum or being supplied predetermined quantities thereof for mixture with other ingredients. The closure plug is removed from drum A and pump adapter B is secured at position with base threads 9 engaging the threads of the bung hole 5. Drum A is thereby adapted for connection to pump C, the latter having its chamber 13 and rigid tube 14 received Within tubular body 6 of adapter B, and cap or fitting 10 is threadingly secured to neck '7 to fix pump C upon adapter B. Flexible tubing 15, which will have been passed through tubular body 6 upon mounting of pump C, will extend to the bottom of drum A so that the entire contents thereof may be pumped without the necessity of tilting of said drum A. Finger grip 12 of pump piston will thus be presented at a convenient elevation for operation whereby an operator need only place a small, ultimate container to be filled at spout 11 and by operation of pump C a pre-measured quantity of the liquid contents of drum A will be discharged thereinto.
Thus, by the use of pump adapter B the heretofore considered unwieldy character of drum A is effectively overcome, since the same may be used in immediate conjunction with filling operations, thereby obviating the need of any intermediate receptacles for transferring the drum contents to the ultimate container. Pump adapter B may be of any desired length so that the finger grip of pump C will be at a comfortable height to conduce to minimum fatigue of the operator. Additionally, it should be noted that pump adapter B may be sized for use with any industrial drum and hence has wide applicability in industry. Furthermore, its usage has proved highly economical from a labor standpoint as well as assuring the avoidance of inadvertent loss of the drum contents. It my be manufactured most cheaply of highly durable material.
It should be recognized that, if necessary for engagement purposes, the threads at neck 7 and base 9 may be provided on the inner surface or bore wall of tubular body 6 instead of outwardly as shown in the drawing.
It should be understood that changes and modifications in the formation, construction, arrangement, and combination of the several parts of the Pump Adapter for Liquid Containers may be made and substituted for these herein shown and described without departing from the nature and principle of my invention.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
