REGEPTACLIE FOR CONTAINING AND DISCHARGING SEMISOLID AND PASTY SUBSTANCES.
resident of Pittsburg, in the county Al-' legheny and State of Pennsylvania, haye invented'a new and useful Improvement in Semisolid and Pasty Substances, (Case 7,) of which the following is a specification.
This invention relates .to receptacles for containing, storing, transporting and discharging semi-solid and pasty substances.
The device is intended more particularly .for putting uplubricants in the form of grease and dls h: rging the same int-o grease cup; of'ma'chines, and the particular purpose is to enable the grease to be supplied to'bearings without liability of d1rt or grit entering the bearings with the grease, and also smearing up or soiling the machinery or hands of the user. The invention, however is not limited to this particular. use, but is adapted-for putting np 1n a.substantially' sealed condition any semi-solid or asty substance, such as Vaseline, cold cream, and the like, and even butter or lard, and delivering the same from the cont-ainer'in any desired quantity or'quantities.
The particular purpose of the present invention is to provide a device for the purpose specified so constructed that it automatically closes the outlet orifice when the operation of discharging the substance ceases. j
v The invention comprises the construction and arrangement of parts hereinafter described and claimed.
In the accompanying drawings Figure l is a vertical section through a device embodying the invention, with the outer orifice closed; Fig. 2 is a similar view showing the outlet orifice open; Fig. 3 is a similar view showing a modification; Figs. 1 and 5 are detail views on an enlarged scale of the discharge portion showing the same in two differentpositions; Fig. 6 is a view looking at the discharge end and showing a modifi- Specification ofLetters Patent.

as formed from paste or paper board. One end of this receptacle is closed by means of the head .2 which may be removable to permit filling the receptacle but which is shown crimped onto the end of the tube 1. This can 'be done after the receptacle is filled.
The head 2 is provided centrally with the discharge orifice 3.
In order to force the semi-solid or pasty substance out of the receptacle there is provided a piston or follower 5 preferably provided with a cup leather or the like 6 for giving a close fit in the receptacle. This piston or plunger is adapted to be moved longitudinally in the tubular receptacle and when so moved forces the material out through the discharge orifice 3. Any suit able means for moving the piston maybe employed, that shown comprising a threaded rod or screw 7 arranged centrally of the receptacle and extending from end to end thereof, and having one endv provided with means forfldtatingthe same. In the form shown in Figs. 1 and 2 the outlet orifice 3 is simply a hole in the head 2, and is adapted to be closed by the end 8 of threaded rod 7 which end is preferably rounded or of conical shape as shown, and forms practically a valve or stopper for the outlet orifice 3. The rod 7 in this case is threaded substantially from end to end, and preferably the threads run left handed." Said rod works in a nut 9 or the like secured to the head 10 crimped or otherwise secured to the tube 1, and at its outer end is provided with a knurled head 11 or the like for turning the same. Somewhat inward from its outer end the rod has its threads cut awaylto form a plain annular portion or neck 12 which in length is substantially equal to the thickness of nut 9. Inside of the plain portion 12 the rod 7 has a collar. or washer 15 secured thereto. p
The threaded portion '14. outside of the plain portion 12 works in the stationary nut 9. Consequently when the rod is turned'this imparts an endwise or longitudinal movement to the rod 7. Wewill supposethat the it moves cndwise until the plain portion or;
draws the end of this rodjfroni orifice-3,
This endwise. movement with- BEISSUED openin the latter. After this the rod is perfectly 'rlb on the inner. face of the 'tube 1 engaging a' groove in'the piston. This rib in thecase of a paper tube will; be a strip of paste board pasted to the innenface of the tube 1, and inv the case of a sheet metal tube the usual crimped-seam ofv such tub'es-forms a suificient rib for this 'purpose' Conse the piston 5to travel toward the 'outletqorifice and force the contents of'the' receptacle out of the same. When the desired: amount of material has been expelled the rod 7 .is
rotated in the opposite direction, thereby backing ofiij'the piston 5 to relieve pressure aon the contents in the receptacle, and at the same 'time' again causing the threaded por- -1 so as to rotate thereon, and is either immovable endwise or at least has only a slight endwise movement thereon. 1 This can be accomplished by'turning the edge of the head 17 over a flange or shoulder 18 on the end of tube 1, or on a collar 19'crimped or other- .wise secured on said tube. When endwise movement is to be permitted a slight space is left between the flange18 on the tube 1 and the inturned flange 20 on cap 17 and it is so shown on Fig. 3. The peripheral edge of 7. In this'form the outlet orifice 3 isformed in a tubular PIOjGQtlOIYPOItlOIl 22 on'lhead 2-,
' said projecting portion being internally cap 17 is knurledor milled as indicated at 21 was to'give a firm grip to rotate the rod threaded. The free end of the threaded rod 7 has a reduced portion 23 which'projects into the outlet orifice 3 and; is externally threaded so as to engage the internal threads insaidoutlet orifice. Thethreads on the projection 14 and in the outlet orifice run 1 the same direction as the-threads on the dy of the rod or screw 7.
*When the receptacleis freshly filled fh piston 5 liesagainst thecap 17, and the proection 23on the screw rodis in theoutlet l shown in opening-"3, the parts being-in the position p Fig; 4.-To discharge the contents the rod 7 is rotated, by turning the cap 17 "thereby causing the piston 5 to travel toward ifthe opposite end 'of' the tube. The rotation lthefOrward travel of -the pistonha-s the of the rod 7 in the proper direction to cause effectof'unscrewing.the projection 23 from the-"outletorifice, but since the .rod is endwise immovable, or only slightly movable endwise, the effect of this is to crowd or bulge the central portion ofthe head 2 outwardly, to the position shown in Fig. 5, i; thereby freeing the outlet sleeve 22 from the pro ection 23 and permitting the contents to escape. The endwise movement of the rod '7, when pernntted, assists in such opening a of theorifice 3, or at least increases the ex-' tent'of the opening. When the desired quantityhas been expelled the cap 17 is preferably turned slightly backwardly. This relieves the pressure on-"the material and permits the resilient head 2 to spring inwardly v l until the outlet sleeve 22 engages the proquently the further. rotation of rod7 causes jection 23 on the screw rod, and further backward rotation of the screw rod causes the oppositely running threads on proj ect-ion 23 to enter the corresponding threads in the,
outlet sleeve and pull the central portion of the head 2 inwardly to substantially flat position, or as shown in Fig. 4,.thereby entirely closing the outlet orifice and substantially sealing the same.
To permit the expand. This is permitted by .light sheet metal, but in case the rod 7 has no endwise movement thehead 2 is referably provided with one or morev radial s its 24-running into the outlet orifice as shown in Fig. 6. To prevent the contents escaping through such slits there is placed immediately inside the head a yielding disk 25 of paper or other suitable flexible material.
' In the use of the-device the grease 0 other. material is filled into the receptacle 'at the factory, and the receptacle is then closed and can be packed, shipped and stored in a practically sealed condition.
The filling is preferably done before the The packagerhashead 2 is crimped .on. practically no external projections and therefore can be safely packed, shipped and handled, and the means for expelling the material-from the package is contained entirely within the package and therefore provides no projection beyond the main casing "and does not add to the length of the latter.
The material is held in substantially a sealed form, and is discharged ina manner to pre-,
vent dirt or grit-5 mixing with the same and is always contained in a tightly closed casing so that the contents will not absorb odors from substances which are stored in the, same room or vicinity.
What I claim is: j 1. A device of the character described comprising a receptacle provided at one end with a discharge orifice, means for forcing the material out of. the receptacle and through said discharge orifice, and a closure for said discharge orifice actuated from said forcing means and arranged to close the discharge orifice-upon reversing the operatidn of the forcing means.
