GOMBTNATTON cONTAiNsR AND GREASE GUN.`

Appncmion mea December 16, 19,25. serial No. 75,851.v

My invention relates to improvements in coinbination containers and grease guns, the objects of which are to provide means whereby semi-fluid greases and the like may be packed to sell and the container used bythe purchaser `as a grease gun by which the grease is delivered under suitable pressure, to provide for a structurewhich is of such l economical manufacture as` willv permit oi thecontainer beingidiscarded lafter use, and to provide means whereby sul'licient Aforce may be applied to the contents to eject it irrespective of its consistency, `further ob.-

i jects are to provide yagainst leakage of the contents of the container between the piston and the side wallsV of the container or through the operating shaft-bearings, and also to prevent the inadvertent movement or' the operating means. Y e f f The invention consists essentially of a. container having a seamed or screw top in which a piston is slidably mounted: and flexibleY tensioning means for raising the contents of the container and ejecting it through a delivery nozzle, as will be more fully describedin the following speciicationfin which Fig. 1` is a sectional view oi one embodis mentfof the invention. l

Fig. 2 is a sectional view ot a modification. `V U V VFig. 3V isa sectional viewrof a further modilication. v Y

Fig. 4 is a sectional view oa further modication showing an operating, shaft mounted outside the body 'ofthe container. Fig. 5 is a 4sectionalview taken on the fline 5 5 of Figure 1.V V l V Fig. 6 is a plan view of the bale taken In the dra-wings'like characters of reference indicate correspomling` parts in each figure. n I i l`he numeral lindicaies generally a con-v tainer prete 'ably made, for purposes of economy,according to' regular can practice. 2 are the side walls,3 thebottom closure, 4 a top closure, 4which may be seamed to the side walls as shown in Figures 1, 3 and 4, or formed with a screw top as at 5, see Fig ure 2. In the top closure 4 a small cap 6, Open to the container body 1 is fitted, and. from this cap a discharge nozzle 7 extends, Which may be oi any suitable shape or length. In opposite side Walls oi! the cap- I provide respectively a capped bearing 8 and an ooenended bearincf` 9 which are )reif-v b Q i erably similar to a hollow rivet and. are secured in place as suchythe bearing 9 is set with. its head orv plan suriace end to the inside of the cap as at 10, the purpose` of which will hereinafterappear.

The ynumeral llindicates a windlass shaft having a tight push lit in thebearings v8 and 9, and extending outwardssomewhat beyond the side of the container body 1.\vhere' it is bent at right angles 4to itself to form av lever 12, the outer extremity of which is again bent `into a loop 13. As atmeans `for pre venting the inadvertent movement oi kthe lever 1 2 I bend the loop transversely, as'` at 14, see Figurei, to conform substantially to the periphery oftheside wall 2 of the container,fanchoffset thev lever adjacent the looplasat 15, so that when the lever is in axial alignment with the'container body a resilient gripping pressure is exerted between the loop13 and the side wall 2 of the container.k y

The numeral 16 indicates avpiston having a skirt or/side walls 17 ,Oi suiiicient length tof insure af parallel movement `when being raised; thisdpiston is superimposed with a bucket 18 having` an upturned peripheral lip 19 and is preferably of some pliable material, so that as `pressure is developed ,upony it incidental to the raising of the piston, the lip isv adapted vto form an effective seal against the side walls 2 of thecontainer body. As a further means of preventing the passage of the grease orothervmatterextremities are bent downwards as at y22,'

see Figure 2, or by any other means whereby one or morek cords, tapes or wires may pass freely around it without appreciable frictional loss. Attached by any suitable means to the bale 20 Or 21, or about the shaft 11 vis one .end of a cord 23 which may be textile,

icc

metallic or otherwise, as maybe required to suit the material packedV in ythe container and to meet the necessary strain imposed upon it; this wire extends in a succession of strands from the bale and over the shaft, the other end being passed through an orilice 2e in the shaft and :knotted or otherwise secured thereto so that the desired purchase may be obtained. It yWill be noticed that the oriiice 2l is formed relatively close to thebearing S), see'lligures l, 2 and 3, and the initial windings 25 of the cord 23 extend therefrom in the direction of "the bearing t) so that assoon yas the shaft `l2 is rotated to dispense any of the contents and further ivindings of Acord lare made about the shaft uf'liich, being led ytowards the bearing crowds up `against t'its `head l() and form a packing A:by which leakage V-tlirough the `bearing' 9 is definitely pre-vented, subsequent rotation of the shaft l2 will build up a second rouv 'off windings which will add `to the etticiency of the packing thusformed.

In `the modiiication shown iin Figure 3, I {it-a parallel sided tubular spout 26 `to which a 'suitable discharge nozzle 27 is aittached, and Ito the ypiston 156 /a tubularpiston rod `28 having apertures'29 in its lower side vvalls. rIhe piston rod'has sliding movement in the spout 26 'andinaintainsithe piston at right angles to the container ibody Walls, thus rendering it possible to form the piston as a flat disc 30, Which Would,lat the time of filling the container, lie in contact With the bottom closure 3 thereof, thereby materially increasing theV grease capacity. A further advantage of this construction is` that the grease flow during` discharge, is derived only from the lower area of thegrease body and the friction developed in discharging restricted to that caused by 5the lgrease flowing over the small areas Lof 'the inside the tubular piston 28 and the ydischar-gii-ig effort required upon the lever 12 is materially reduced, Whereas in "otlher'forms of piston 'discharge the Whole body of grease h as :to move upwards with the piston travel With a resultant skin friction equal to the greater area of the container side Walls.

In the modification shown in Figure 4, a bale 3l is iitted Within the discharge nozzle 7 to which it kmay be soldered -or otherwise rendered leak proof. The top closure indicated by the numeral I32 is cupped and the piston 33 is cupped ina similar manner, the piston is provided with a skirt 3ft to form a guide 4and is provided' with a small rebate 35 at the top ofthe skirt to receive a suitable `packing ring 36.

rlhe numeral 37 indicates a bale upon the piston and 3S is a felt Washer which seals a small orifice 39 through which, and the Washer, the outer end of the 'Winding cord Lit) is threaded, the cord then passes 'through a slot il in the bottom closure l2 and is wound onto a shaft t3 which is journalled in opposite sides of the bottom rim lit of the container side walls and outside the container body. .By clipping the .piston $33 the effective length for rguiding spllrposes is increased and by capping the top closure in the same manner as the piston, ythe contents ot the container may-'be completely dischargedr at Will.

What I claim as my invention is:

a container, a closure for the container, provided with a' discharge nozzle, bearings yin said-closure, a Windlass rotatahlymounted in said lbearings extending'outwardly beyond the side of the container and bent at right angles to form a lever arm, ahandle loop on the extremity of lsaid lever bent to conf form to the contour of a Wall of the container to grip said wall, `a rpiston for the container and ieXible connection Imeans between the .piston and said Wi'ndlass shaft.

`12. A container and grease gun comprng, a container', a closure for the container, provided with adischarge nozzle, bearings in said `closure, a windlass rotatably vmounted in said bearings extending outwardly beyond the sideiof the `contaliner` and vbent at right angles to form a lever arm, a yhandle 4loop on the extremity of said lever bent'to conform to the contour of a Wall of the container to grip said Wall, a piston in the container flexibly connected to the ivindlass shaft and a. hollow piston stem having a plurality of orifices therein commlmicating with the discharge nozzle.

3. A device of the character described and in combination, a container iprovided with a piston and a discharge nozzle, a -closure member comn'iunicating with the discharge nozzle, a Windlassshaft flexibly connected to the piston and journalled in said closure member, means integral with said shaft wilh-` out the container for operating it, and means integralwith the aforesaid means for engaging vWith the container.
