To all whom it may concern:-

Be it known that we, MARTIN B. LnAvnNs and HERBERT D. VVILsoN, citizens 'of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Exhauster for Original Commercial Containers, of which the following is a specification. f r

The primary object of this invention is to provide an exhauster for commercial hard grease containers so that the contents of an original container may be easily and conveniently forced therefrom.

,Another object of the invention is to provide an exhauster of this nature which is adaptable to varlous slzed contalners.

Another object of the invention is to provide a device which may be quickly connected to a commercial container of grease in such fashion that the grease may be forced therefrom through a spout.

With these, and other objects, in view the invention consists of certain novel features of construction, .combination and arrangement of parts, as will be hereinafter fully described, illustrated and claimed.

In the accompanying drawings: Figure l is a longitudinal sectional view through the exhauster and container; Fig. 2 is a side elevation, partly in section showing the plunger forced about midway of thecontainer;

. Fig. 3 is a section on the'plane of line 3-3 of Fig. 1; Fig. 4 is a section on the plane of line H of Fig. 1; Fig. 5 is a perspective view of the spring expansion ring used in connection with the plunger.

Referring in detail to the drawings by numerals: 1 designates an original commercial container for hard grease and similar substances. A threaded shaft 2 extends longitudinally through the container and is connected at one end to a plate 3 having a spider-like center formed by the arms 4 and ring 5. The shaft 2 projects through the ring 5 and is connected at its terminal to a washer or disk 6 which limits the movement of the shaft in one direction. A spout 7 is connected to the plate 3 around the central spider portion by means of an internally threaded flange 8 into which the spout threads. An adjustable head or plunger 9 is employed to force grease from the container 1 and this plunger which is preferably made of canvas is held taut and into close engagement with the inner side of the Specification of Letters Patent.

container by a spring expansion ring 10. The ring is split as shown in Fig. 5 and may be fitted into cans or containers of differentdiameters. f

The plunger is strengthened and reinforced by a follower 11 in theform of a cir 1 cular plate. The plate is centrally apertured to permit the passage ofthe threaded shaft 2 and is provided with an outwardly extending internally threaded neck 12 through which the shaft 2 also extends. A plurality of fingers 13 are held. slidably in engagement with the outer side of the followerby straps 1 1 and these-fingersare provided on their inner terminals with teeth 15 to catch in the outwardly facing teeth 16 of the follower and prevent inward movement of the fingers. The fingers areprovided on their outer ends with extensions 17 which engage the lower edge of the expansion ring 10 and forcesaid ring inwardly along with the follower-4 A removable hand wheel. 18 fits over the outer endof the shaft 2 and is held against rotation relative thereto by means of the squared portion 19 of the shaft. This wheel is preferably made hollow so as to inclose the pointed end 20 of the shaft.

.When it is desired to force grease from .a commercial container such as indicated by the numeral 1, the shaft 2 is forced through the bottom of the container and worked about so as to form an enlarged opening 21 through which the grease is discharged. The top is then removed from the container and the plunger 9 and follower 11 fitted into position as shown in Fig. 1. The fingers 13 may be forced outwardly so as to fit various sizes of containers. hand wheel 18 is slipped over the outer end of the shaft 2 and the shaft turned by means thereof the follower and plunger will be drawn inwardly to expel the contents of the container.

In order to conveniently handle a commercial container of grease when our exhauster is applied thereto a band 21 having a handle 22 is clamped around the body of Now when the tion with commercial containers of various port said spring means.

method of utilizing said contents:

Although we have shown and described the preferred embodiment of our invention, it will be'understood that minor changes of construction and arrangement of parts may be made without departing from the scope and spirit of the invention as claimed.='

'What we claim is:

-l.*ln an exhauster for original containers, a flexible plunger, spring means'for holding said plunger taut, a follower, and means adjustablymounted' on the followerto sup- Y 2." In an exhauster for original containers,

i arotatableshaft adapted to extend through a container, a follower through which the shaft passes having threads'engaging said shaft, a plunger opposed to said follower, and means carried by the follower to support the'plunger, a r V 3. Ina device of the character described, a flexiblejplu'nger, springmeans for holding said plunger taut,-a follower for rein- I forcing and actuating the plunger, and ra- .dia'l fingers slidably connected to the follower to support said-spring means.

4. Incombination with-a commercial container, means for expellingfthecontents of the container, said means comprising a shaft adapted to be extended through an opening formed in the bottom of the container, a plate'mounted exteriorly of the container to which said shaft is rotatably connected, a plunger actuated by the rotation of said shaft, and a spout mounted in alinemcnt with said opening and shaft.

5. In a device of the character described, a flexible plunger, spring means for holding said plunger taut, a follower for reinforcing and actuating the plunger, radial extensible fingers connected to the follower to support the spring means,'and means to hold said fingers in extended position.

6. In an exhauster for original containers, at flexible )lunger, spring means for holding the plunger taut, a follower for actuating the plunger, a plate having teeth thereon mounted 011 the plunger and secured to the follower, radial fingers slidably mounted on the plate and engaging the spring means at their outer ends and the teeth at their inner ends, said inner ends being formed with teeth. g

In testimony whereof, We have hereunto set our hands at Los Angeles, California, this 27th day of January, l915.
