INVENTOR BY w ATTORNEY rao @n ernten.



Specication of Letters Patent.

Patented May 7, i918.

Application led July 19, 1917. Serial No. 181,456.

To all whom t may concern.'

Be it known that I, FREDERICK I-I. SEARLE,

- a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio', have invented a certain new and useful Improvement in Grease-Containers, of which the following is a specification.

The invention relates to packages adapted to contain and dispense lubricating grease or other viscid material, and the object of the invention is to provide a simple, economically manufactured container y from which the grease may be easilyexpelled in the desired quantities, from either end, closed eiiiciently for transportation or storage, and which may be easily and quickly refilled for another discharge.

Thev invention consists in certain novel features and details of construction and ar. rangement by which the above objects are attained, to be hereinafter described and claimed.

The accompanying drawings form a part of thi specication and show the invention as it has beencarried out in practice.

Figure 1 is a side elevation of the container in the closed condition.

Fig. 2 is an elevation of one end or head.

Fig. 3 is a similar view of the other end orhead.

Fig. 4 is an axial section taken on the lFine 4 4@ in Fig. 3, and corresponding to Fig. 5 is a similar section showing the container in the partially discharged condition.

Fig. 6 is a transverse section, on the line 6 6 in Fig. 4.

Fi 7 is a similar section taken bn the line ,-7 in Fig. 5. A

Fig. 8 is a face view of the plunger for expelling the contents.

Fig. 9 is an elevation of an extension nozzle.

which will lbe termed the delivery head, has a nozzle C on its outer face, shown as extending radi-ally from the centerand closed by a screwcap C1;

Within the cylinder is a plunger or fol-v lower D, fitting piston-Wise therein, consisting preferably of a circular disk of wood having a packing-ring D1 of fabric or the like extending around its periphery to serve in making a close joint between the movable follower and interior of the cylinder. The disk is recessed at the center on both faces as indicated at (l.

In filling the container the follower D is located at or near one end of the cylinder covered by the closed head B, and the remaining portion of the body or cylinder is then filled with grease M, and the delivery head B1 applied withits nozzle C closed by the screwcap C1. In this condition the filled container is ready for transportationl or storage.

To discharge the grease the closed head Bis removed to expose the face of the follower D, the screwcap C1 is removed from the nozzle, and by thrusting on a rod F or other suitable implement inserted through the open end ofthe cylinder with its point enga ed inthe conical recess al in the exposed face, the plunger is forced toward the opposite end ofthe cylinder expelling a corresponding quantity 'of grease through the nozzle C.

When by a single or a series of such thrusts or application of pressure the contents has been discharged as described, the delivery head B1 is removed and the closed head B substituted therefor, the cylinder is again lled and the delivery head B1 applied at the opposite end. The container is thus conditioned again to deliver by a reverse movement of the follower D. The filling and emptying operations may be repeated indefinitely.

C2 is a tubular extension having a screwthread at one end C3 matching to the thread of the nozzle C and is applied to the latter in place of the screw cap C1 to lengthen the nozzle as in Fig. 5, and permit the grease or other contents to be directed to the desired point or to the portion of the machinery to be supplied.

It is intended to join the extension C2 detachably to the container or otherwise present it therewith, and also to supply a suitable thrusting tool F, but the extra nozzle or extension vmay be omitted, and in the absence of the tool F, any stick or -rod of' the proper length IWill serve,4 preferably ointed to ,engage the central recess d in the ollower D to insure equal distribution of strain on the latter in the discharge movement and thus avoid any tendency to cramp or bind in the cylinder.

Modifications may be made in the forms and proportions and in the materials employed, and the invention may be applied to other uses to which it is adaptable.

I claim z- 1. The container described, consisting of a cylindrical body having its ends screwthreaded, interchangeable heads threaded to match to either of said ends, one of said heads having a delivery nozzle and the other closed, a plunger insaid body having a central recess in each face and arranged to be exposed by the removal of said closed head, and to be moved axially toward said .delivery headv by pressure applied through a rod introduced vthrough such open end of said body and engaged in such recess.

2. The container described, consisting of a cylindrical body having its .ends screwthreaded, interchangeable heads threaded to match to either of said ends, one of said heads having a, radially disposed delivery nozzle and the other c1osed,'a plunger in said body having a central recess in each' head.

A3. The container described, consisting of.

a cylindrical body, removable heads closing the ends of said body, and an unconnected plunger in the latter adapted" to be` forced axially in either direction Withoutremoval from said body by pressure appliedI thereto through an open end of lsaid body afforded plnly by the removal of the corresponding 4. The container described, consisting of a cylindrical body, interchangeable vheads closing the ends of said body, and an unconnected plunger in the latter adapted to be forced axially in either direction Without removal from said body by pressure applied thereto through an open' end of said body afforded only by the removal of the corresponding head.

In testimonythat I claim the invention above setl forth I alix my signature, in presence of two Witnesses.
