-To all 'whomz' may concern Be it known that JAMES l?. CnM'nN, a resident of Pittsburgh, in the filtzate ot' Pennsylvania, have invented a new und use ful 4Improvement in Receptacles for Containing and Dischargingr Semisolid and Pasty Substances, of which the 'Following' is a specification.

This invention relates to receptaufles tor containing7 storingi trimsportingg,V and discharging semi-solid and pest); suhstnnes.

The device intended. among other uses, forpnttingi up luhricants in the torni ot' grease :ind/disrhnrgiug the saine into grease Cups o machines, :1nd the particular purpose is to enahle the grease tov he supplied to hearings without liahility of dirt or gritentering,r the hearings with the greasm and also smearingr up or soiling' the innehinery or hands of the user. The invention, hou*- ever, is not. limited to this particular use.'

but is adapted. for puttingv up in a suhstanlially sealed eondltlon, any semi-solid or is u vertical section through a devia-e enibodying the invention, with the outer oritice closed; Fig. 2 is a similar View showing;r the outlet oriliee open; Fig. E is a similar View showing` a modification; Figs. 4 and 5 are detail views on an enlarged seule et the discharge portion, showing the sinne in two different, positions; Fig. 5 is a. View looking at the discharge end :ind showing),- a n'iodilication, and Fig. 7 is a sectional View thereof.

The receptacle or container itself may he of any desired size or shape and may be built up or constructed in any desired Way and from any desired material. As shownI in the drawing-1 the receptacle proper is termed as a suhslantinily cylindrical tuhe 1 which may he constructed of sheetmetnl or other suitahle thin suhstance und is shown as formed trom paste or paper hoard. (lne end oi' this reeeptacle is closed hy means of the head which ma)7 he remorahle 'to permit 'filling the receptacle hut which is. shown erilnpi'nl onto the end ot' the tuhe i. rlhis can he done a'lter the receptacle is lilled. The head 2 is provided centrallyY with the discharge orifice il, whirh. as shon'n, is at'. the extreme end otl Vthe container.

suhstance out ot the rect-ptaultl there is provided :l pistou or follower 5 prefernhly provided with a cup leather or the like t3 tor giving' :1 elo-se lit in tin` rtlreptnrle. ri`his piston or plunger is adapted to he moved longitudinally in the t-uhulztr receptacle and when .so moved torres the niateriid ont through the discharge oritice 3. .'ltny suit :dile moans for mornin the iliiston may he employed, that shown comprising :t threaded rod or screw 7 arranged rentrnlly ot the receptacle :1nd extending from end to end thereof. and having one end provided wit-h menus tor rotating the sainte. ln the l'orui shown in Figs. i and i). thet'iutlet oritice 3 is simpljv a hole In the head 2, and iid-apted to he closed hy the end S of thrended rod i', whirh end preternhly rounded or of conical shape :is .shim-n, and toi-ius praetiealiy :i valve or stopper 'for 'the outlet. orifice Si. The rod i" in this case is threaded .substantially troni end to end, and pret erahly the threads run left handed. Said rod works in :t nut Q or the like secured to the head i() crimped or otherwise secured to the tuhe l, and at its outer end .is provided with a linurled head il or the like, for turningl the same. Somewhat inward from its outer end the rod has its threads ent await7 to form. a plain annular portion or neel( l2 wirieh in length is substantially equal to the thickness oinnut 9. inside of the plain port-ion 1.2 the roti 7 has a Collar or washer 13 securedy thereto.

The threaded poi-'tion 14 outside of the plain portion 12 Works in the Stationary nut 0. Consequently when the rod is turned thisy imparts mi endwise or longitudinal movement to the rod 7. We will suppose that the outlet oriticc 3 is closed by tl of rod 7. It' said rod be rotated in proper direction it moves endwise. until plain portion or neclt l2 get: into the nut 9, after which further endwise movement is arrested by collar t3. This endwise Inovenient. withdraws the end of the rod from orifice il, opening the latter. tter this the rod is perfectly fi-cc to rotate but is held against endwise movement by collar 13. The piston 5 is held againstv rotary movement-by the combined frictionzil action of the cup leather against the tube walls and by o loi gitudinal rib l5 on the inner ltace ofthe tube l engaging a groove in the piston. This rib in the casev ot' a paper tube will be a strip oit paste board pasted to the inner tace of 'the tube l, and in the case of a .sheet metal tube the usual crimped senin ot such tubes forms a suilicicnt rib for this purpose. Consequently the further rotation oi rod 7 causes the piston 5 to travel toa'ard the outlet oriw tice and force the contents ot' the receptacle out of the saine'. lll/*hen tho desired amount of material has been` expelled the rod 7 rotated in the opposite direction, thereby backing od the pistonl 5 to relieve pressure on the contents in the receptacle, and at the same time again causing the threaded por tion 14 to engage not 9 :ind more the rod 7 endwisc until its end tl closes the orifice 3.

lWith the orin shown in Figs. d 'to the threaded rod 7 is rotated by being secured to a cap 17 which is fitted on the end ot the tube l so as to rotate thereon. and is either immovable endwise or at least has only e slight endwse movement thereon. This can be accomplished rby turning the edge o" the Vhead 17 over a flange or shonlderf on the end of tube l, or on a collar 19 crimped or otherwise secured on said tube. lihen endwise movement is to be permitted a slight space is left between the flange i8 on the tube l and the inturned 'flange 2G on cop 17, and it is so shown on Fig. 3. pe ripheral edge o't` cap 17 isllfnnrled or milled as indicated at 2l so esto give a firm grip to rotate the rod 7. ln this forro the outlet orifice 3 is formed in a tubular projecting; portion 22 on head 2, said projecting portion being internally threaded.l 'The tree end ot the threaded rod 7 has a reduced portion 23 which projects into the outlet orice 3 and is externally threaded so as to the internal threads in said outlet critico.

, The threads on the projection let. and in the outletoritice run -in the saine direction as the threads on the body of the rod or screw 7.

When the receptacle is freshly filled the piston 5 lies against the cap 17. and the pro icction 23 on the screw rod is in the outlet opening 3, the parts boing in the position shown in Fig. 4. To discharge the contents the rod 7 is rotated'7 by turning the cap redit-Eo 1.7 y causing the piston to travel tou'aro ine opposite end ott the tube. The

'or bulge the central portion of the head 2 outwardly, to the position shown in Fig. 5, thereby freeing the outlet sleeve 22 from the projection 23 and permitting the contents to escape. rilhe endwise movement oitl the rod 7, when permitted, assists in such opening the crit-'ice 3, or et least increases the extent of the opening. lllhen the desired quantity lies been expelled the cap 17 is preferably turned slightly bacli:u 1ardly. This relieves the pressure on the material ,and permits the resilient head 2 to spring inwardly until the outlet-sleeve cngares the projection 23 on the screw rod, and further backward rotation ot the screw rod causes the opaositely running threads'o-n projection 23 to enter the corresponding threads in the outlet sleeve and pull 'the central portion et the head 2 inwzirdly to substantially itat position, or es shown in Fig. it, thereby entirely closin the outlet orifice and substantially sealing the saine.

To permit the heed '2 to bulge outwardly at its center it is necessary that. it yield or pand. lf .is is permitted by light sheet metal7 hut in case the rod 'l has no end-- Wise .movement the heed 2 is preferably provided with one or more radial slits .24 running intothe outlet orifice shown lin Fig. Toprevent the contents escaping through such slits there is placed immediately inside the head a yielding disk 25 of 'paper or other suitable flexible material, .ln the use of theu device the grease or other material is filled into 'the receptacle t the factory and the receptacle is then oecd, and can be packed, shipped and ored in a practically sealed condition. The tilting is preferably done before the head 2 is crimped on. The package has prec ieztlly no external projections and therefore-ran be safely packed7 shipped and handled, and the means for expelling the material from the pgclrage is containedenm tirely within the package and theretore pro vides no projection beyond the'main casing end does not add to the length of the latter. The-material is held in substantially a sealed term, and is discharged in a manner to prevent dirt or grit mixing With the saine and is always contained in a tichtly closed casing so that the contents will not absorb odors from substances which are stored in the samel room ,or vicinity.
