INVENTOR 23 F11; WITNESSES w ir 1 lSTATE'S'f1PM-ENID OFM@ JAMES'F. CRA'V'EN, OF PIITTSBURGH, PENNSYLVANIA, ASSIGNOR TO CRAVEN ENGI- NEERING COMPANY, OF PITTSBURGH, PENNSYLVANIA, A 'CORPQRATION `:OIF

-invented a new and useful. Improvement in Closures for Grease-Guns, of which the following is a specification.

This invention relates to closures for receptacles for containing liquid,seIni-1iquid pasty or semi-solid substances, and more particularly to closures for oil cans, greasev guns and the like, which vare Vadapted or intended 'for discharging the contents of. the receptacle through a spout or nozzle to oil or grease cups of machines and the like. f

The object of the invention is to providel a closure for such receptacles so arranged that the act of attaching a removable spout to the receptacle operates the closure to open the discharge orifice, while the act @tdetaching the spout operates the closure to close the 'discharge orifice.

The invention comprises the construction and arrangement of scribed and claimed In the accompanying drawing Figure 1 is a vertical section through a grease gun havparts hereinafter deyingany invention applied thereto; Fig. 2 is a top view of the-closure in closed position; Fig.v 3 is a sectional view showing a modi# iication; and Fig. 4 1s a section on the line In the drawings the numeral 1 represents the body of a ,receptacle of any kind for containing a. liquid, semi-liquid, pasty or semi-solid substance. It is represented as a can of general cylindrical `form having the body formed of the tube l, show-n as made vided 'with of paste or paper board, but/(which may be madefrom sheet metal or other suitable Inaterial, having a bottom' 2"and a head 3 of sheet metal suitably secured to the ends of the body in any suitable way, such as by crimping.

The head 3 is `provided with a tubular extension or rack- 4, whose end 5 is protheY discharge orifice 6. Rotatably secured vto g the end 5 of the neck 4 is the closure 7 which is shown in the form of a cap or inverted cup loosely fitting over the neck`4.- and secured thereto Aby the rivet -8 or other means to keep it from separating from the sleeve but perspecifieation of Letters raten-1:.

`cap 7 has a of the'opening 1l bent inwardly .to form a' -cap 7 in both directions. metal at one edge of the opening 6 is proto rotate in the direction of the arrow,4

CLOSURQE FOR GREASE-GUNS.

drical or side `portion 9 of the cap is provided with-A external screw threads forv recelvin 'the correspondingly threaded inner end o the delivery spout 10 which will be of such length and shape as to deliver the substances tothe grease or Ioil cups of ma- 'chinery or like us raten-ted Aug. a7, isla.

-The end ot the cap 7 is provided with an opening 11 which in shape and size preferably corresponds to the opening (iin the end of neck 4, and which is adapted to register with charge of the material from the receptacle, or to be brought out of register with the opening 6 to close the discharge oricef The portion of the metal at the edge tongueor projection l2 extending into the opening 6 and adapted to contact with the edges of the latter to limit thel rotation of the PreferablyI the vided'with a notch 13-to receive the projection 12 to insure the complete closin of the discharge orice in one position o? the cap7.

The parts are so arranged that the incre act of screwing the spout '10 onto the cap 7, by the frictional engagement threads--at least at the end of the screwing down of the spring-causes the cap 7 Fig. 2, to bring t-he openings 11 vand 6 into ister, while the mere act of unscrewing the spout causes thecap 7 to rotate in the oppo site direction and cause the head of the cap 7 tocover the opening 6 and hence close theldischarge orifice to prevent further'material from escaping from the receptacle, or dirt to enter the same.

Figs. 3 and 4 illustrateua'modification in which, the spoutI 10 is threaded directly to the neck hit'of the receptacle and is provided with an inwardly extending tongue 14a which engages the tluted or roughened periphery 'of the cap 7a which is pivotaliy mounted on the end of said neck, as in Fig.

Y1. In this modification when the spout is be ing screwed onto the neck the tongue 14 engages with the periphery of the cap and rovrtate's the latterto open thedischarge orifice,

and at the beginning of the unscrewing operation-the cap is rotated in the opposite direc ytion to close the discharge, orifice The the opening 6 to permit theA disof the" res- 17 provided with a cup leatherV 18 or'thev like yielding or expanding means for forming a close fit in the receptacle, andprovi ed witha threaded opening 19 in which works a-threaded rod or screw 2O by the rotation of which the piston is caused to move lengthwise in 'the receptacle to force theA substance out of the same. `The screw 20 is rotatably but endwise immovably secured to the body in any suitable manner, such as Y20 by extending the same through the bottom 2, and providing the same with a shoulder or washer 22 on the inner side of the bottom,

so that said screw can rotate but' is endwisc immovable. The outer end ofthe screw is 25 provided with a handle or key 23 with which to rotate said screw. It is obvious that when' the screwv 20 is rotated it causes the piston or follower 17 to move endwise in the receptacle and force the substance out of the same. The piston or plunger is held against :rotation by frictional contact with the walls thereof, or Vby other means, such as a longitudinal projection or rib 24 in the receptacle, which engages a notch in the periphery of the piston or follower.

yVarious other means than thoseillustrated i may be provided for forcing the substance.

f connected to the rece tacle and yendwise imout of the receptacle.'

vThe device described is intended princi- 40 pally for lubricating purposes, where the receptacle must be stored between successive uses,-suchv as on automobiles,or where it is desirable to remove the spout for storing the receptacle. The deviceis however adapted to a variety of uses..

.WhatIclaim is: l. A receptacle having a neck provided witha discharge orice, a member movably mounted on the receptacle for closing the` discharge orifice, a removable delivery spout adapted' t'o be placed over said neck and to `ble secured tp the receptacle and so arranged f that the act of securing the delivery spout nieves said-member in 'one' direction on the receptacle to open the discharge orifceand the act vof detaching the spout-moves it in reverse direction to close'l the discharge orifice. 5
