Patented Jan. 12, 1937 UNITED STATES PATENT OFFICE WAGON CAN O R. SIMILAR BECEPTACLE Application April 5, 1933, Serial N0. 664,593

8 Claims.

My invention relates to cans or similar receptacles usedfor transporting liquids, and more especially to what is generally termed a wagon can in which gasoline, oil, or the like is transported; the cans being placed in wagons or trucks for the purpose.

The primary object of this invention is the production of a can which is durable in construction, inexpensive, and liquid-tight, so that when transpor-ting the ca-ns in or on wagons or trucks, the contents thereof cannot spill.

Another vobject of my invention is the provision of a canso constructed as to resist Wear Whenpulling or dragging-the same along a portion of the wagon or truck, `or over a iioor or otherv surface.

Another object of my invention is the provision of means for conveniently carrying the can in substantially vertical position and for more conveniently pouring out the contentsof the can.

A further object is to provide a cap or `closure for the can which will completely seal the same and be irremovably secured to the can, and which, when moved into open position, will not 1interfere with the pouring out of the contents, especially when pouring the contents from the ca while vin an elevated position.

A furtherA object of my invention is to provide a sealing cap or closure for the can, which may be swung vinto either open or closed position, and wherein pressure applied to the cap or closure, while closing the same, will vassure equal pull on the cover at opposite sides ofthe neck of the can; thus assuring equal pressure on the sealing element within the cap or closure against the upper edge of the neck.

Astill further object of my invention is the provision of two handles to be grasped simultaneously during the act of pouring out the con tents of. the canso that the -cover will ,not swing on itsvpivots and soethat more eiective control ofthe can during .the pouringV action is assured.

With-these vand vother'objects in View to appear hereinafter, my invention consists in the novel features of construction `and in the arrangement and combi-nation of parts to be hereinafter 4described -and :more particular-ly pointed out yin the subioined claims.

Cans of this type are invariably made to -contain several gallons Vof liquid; usually from five gallons upward. They are constructed of comparatively heavy gage material, due to the fact 10 that they are subjected to rough handling, not only in placing them upon a wagon, truck, or other means of transportation, butin removing. them from such means of transportation. When filled with gasoline, oil, or other liquids, they are 15 of considerable weight, and oftentimes are dragged along a roadway, garage iioor, or other surfaces, or dropped from` elevated points while guiding them to maintain verticality; all of which tend to subject the lower Aends of the cans to extreme wear and strain.

Wagons or .trucks used for transporting cans of this type invariably have can Vshelves or supports at a height a considerable distance above the roadway, which necessitates lifting them a 25 considerable height; andthe means'provided for handling the cans whenA placing them upon a wagon or truck, .or removing` them therefronndo not serve very Well for carrying the cans from the wagon to the interior of garages, ,or other places, of delivery. Moreover, since .the contents of cans of this type are usually poured into larger receptacles, or into storage tanks, the pouring neck of the can is preferably eccentrically mounted lon `the 'body portion for'the purpose of `facili- 35, tating the pouring of the contents into Athe receptacle or storage tank without causing any portion thereof to be spilled or wasted.

My improved can is designed to overcome, eliminate, or improve the shortcomings of cans of the type mentioned; to facilitate the transporting and handling of such cans and the pouring .quali-ties thereof; to so construct the -cans to insure longer life, and to otherwise furnish advantages with the use of such cans. 45

In .the construction of the can I provide acylindrical body portion Ill of comparatively heavy gage ysteel-material, the peripheral wall Il of which may be circumferentially ribbed or beaded both :inwardly and outwardly to stiien the metal and lend 'to the attractiveness of the can.

,Fitted into the lower end of the peripheral Wall Il is a bottom I 2, which is dished to provide a downwardly-directed flange I3 lying in contact with the interior `surface of the peripheral wall at its lower end and which is Welded, soldered, or otherwise secured in place in a liquid-tight manner. While the circumferential beads may be provided at various elevations of the peripheral wall for strengthening and embellishment, I provide an internal bead I4 on said peripheral wall II directly above the bottom and against which said bottom bears, thus fixing the limit of insertion of the bottom into said peripheral wall from its lower end.

A reinforcing or wearingl band I5, preferably of heavier gage than the metal of the body .portion IIJ, surrounds the lower end of said body rportion, and at its lower edge it has an inwardly-directed flange I6 which, when theband'is positioned in place, bears against the lower edge of the peripheral wall I I and the lower edge of the flange I3, thus providing an unbroken and unseamed contact surface I1 at the lower end of the can. This band with its flange I6 thus protects the seam between the peripheral wall I I and the ange I3 of the bottom and prevents. separation of .this seam, which would tend to voccur under rough usage in dragging the can over rough portions orl elevations of garage floors, sidewalks, or portions of a wagon or truck.

It is to be noted that the internal bead Ill is formed by exteriorly grooving the peripheral wall II, as at I8, and into this groove so formed, the upper marginal portion of the band I5 is swaged; thus the band is locked to thefbody portion of the can in a secure manner, and in addition to strengthening the bottom of the can, which is subjected to the greatest wear, it assures liquidtight maintenance of the seam between the periphral wall II of the can and the flange I3 of the bottom thereof. Y

A top wall I9 is provided for the can which is connected to the upper end of the peripheral wall II of the can in any approved manner capable of joining the two together in a liquid-tight manner. This top wall varies in its inclination from a given point at its base or line of connection to the peripheral wall I I to a point diametrically opposite, the upward inclination, being greatest at the last-mentioned point so that an opening is provided in this top wall, or shoulder wall as it may be termed, which is eccentrically disposed with reference to the base of said top or shoulder wall and the peripheral wall II. This top` or shoulder wall therefore is gradually reduced in diameter from the peripheral wall II upwardly, and it has a neck 29 fitted into its opening which is secured thereto in any approved manner, `assuring a liquid-tight connection between the two, The wall of this neck is of heavier gage material than the top or shoulder wall of the can, and is preferably formed of a short length of seamless steel tubing, all of the parts described constituting the body portion of the can, which when united by welding the joints or seams, is rendered liquid-tight under .such methods; but any other method of rendering them liquid-tight may be employed. The neck 20 is therefore eccentrically arranged with relation to the remainder of the can, and the pouring opening at the upper end of this neck is therefore off-center, which facilitates the pouring action without tendency to spill over the edge onto surrounding parts while emptying the contents into a receptacleor storage tank. By eccentrically mounting the neck on the upwardly-tapered top or shoulder wall I9, the latter wall has greater slope in one direction than in its directly opposite direction, the slope gradually becoming diminished from its place of greatest slope to that of its least slope.

Welded or otherwise secured to the top or shoulder wall I9, is a rigid upwardly-directed handle 2|, which is for convenience in handling the can, positioned with its center directly over the plane of greatest slope of the top or shoulder wall I9 so that its points of attachment to said wall are at opposite sides of said plane This handle comprises a concavo-convex grasping portion 22 spaced from said top or shoulder wall, and'. depending end securing portions 23 bent outwardly at their lowerends in contact with said top or shoulder wall, said outwardly-bent portions being welded or otherwise suitably secured to said wall.

Y The grasping portion 22 is positioned to one side of the center of the body portion of the can and a considerable distance from the neck, forv a purpose to appear hereafter.

A cap or closure 24 is providedto close the upper open end of the neck 20, and this cap is formed of sheet-metal stamped into circular form with depending flanges 25 to provide a dish-like formation for the same. Retainer or lock ears 26 extend integrally from the flange 25 and lie on opposite sides of the neck. Positioned within thecap or closure thus formed is a sealing disk 21, which may be constructed of fiber or other slightly compressible material and which, when the cap is placed on the can so as to close the latter, lies against the upper edge of the neck. The flanges 2@ are curved inwardly at their lower ends to retain the sealing disk within the cap or closure, as clearly shown in Fig. 3, and by reason of this construction the cap is of somewhat greater I diameter than the neck of the can; the advantages of which will hereinafter be set forth.

The flanges 25 extend from ear to ear and serve as a curb wall to retain the cap or closure on the can in the event of said cap or closure becoming accidentally loosened, and each of the ears is provided with an angular slot 28, closely approaching L-formation; thus providing two slot portions 29,

30, disposed at a slightly obtuse angle to eachinate all possibility of the formation of open fractures in the metal.

Extending through the slots 28 are combined pivot and lockpins or trunnions 33, which project from the neck of the can at diametrically opposite points. These pivots or trunnions have reduced portions 34 forming shoulders 35 which bear against the outer peripheral face of the neck 20, and these reduced portions are passed through the wall of the neck and riveted at their inner ends. The outer ends of said pivots and lock pins, or trunnions as they may be termed, are provided with comparatively large heads 35 which are preferably slightly spaced from the edges of the flanges 3l projecting outwardly from the slots. The diameter of each of said pivots or trunnions is such as to freely t through the slo-ts 28 so as to enable the cap or closure to travel thereon and swing freely to the right or left, as indicated by dotted lines in Fig. 1. The iianges provided on the slots and serving as the walls of the slots llt being smooth, eliminate excessive friction on .the pivots or trunnions, and consequently pressure applied to the cover when closing the same is equalized: and assures equal pull at opposite sides of the neck, assuring even pressure on the sealingdisk 2Iat all points of contact with the upper edge of the neck.

It may here be stated that by providing a cap or closure of a somewhat larger diameter than the diameter of `the neck 2l), and spacing the inturned lower edge of the flange of this cap or closure from the outer surface of the neck, .and also the retainer 'or lock ears, self-adjustment of the cap or closure is provided, so that in the event that the pivot or lock pins are not exactly Lat the saine elevation, or not exactly diametrically oppositely disposed axially, the cap or closure may inove rlaterally in any radial direction, yet retain the necessary relation between said pins and the slots to assure a secure locking of the cap or closure in the neck with the sealing disk of said cap in contact with and under equal pressure around the entire upper edge of the can neck.

It is to be noted that, while the upper portions of the ears 26 conform tothe curvature of the retainer flange 25, their lower portions from approximately the plane of the slot portion 30 downwardly, are flat or straight-lined transversely.

It is further to be noted that the ears at opposite sides of the cap or cover are reversed; the vertical portions 2S of the slots 28 being in line diametrically, while the substantially horizontal portions 3l), which may be more particularly relerred to as wedge portions, extend in opposite directions from the vertical portions. The vertical portions 29 of the lock or retaining slots are closer to one edge of the ears `than the other.

When the can is closed the sealing disk 2l of the cap or closure bears marginally against the upper edge of the neck 2li, and the lock or pivot pins or trunnions, are wedged within the wedge portions 3D of the slot, said wedge portions trending slightly upwardly from the upper ends of the vertical portions so as to rmly draw the cap downwardly under rotation. So positioned, the wedge portions 3l] of the slots 28 lie at opposite sides of a vertical plane passing axially through the lock or pivot pins or trunnions, and assurance is had that the sealing disk is liquid-tight under contact with the upper edge of the neck.

For conveniently manipulating the cap or closure an upstanding handle 31 is riveted or otherwise secured to the upper surface of the cap or closure, and while this handle may be of any convenient construction, `it trends in the same general direction as the handle 2| and is preferably iormed with a hand grasp 38 spaced from the cap or closure and extending diametrically thereover; depending legs 39 at opposite ends of the hand grasp, .and inwardly-directed ears 40 which lie against the top of the cap or closure and which may be riveted, welded, or otherwise secured thereto. The formation of this handle may be varied, but for the purposes .of embellishment I have designed the saine as shown.

When it is desired to pour out the contents of the can, the handle 31 is grasped and the cap or closure 24 rotated, thereby to cause the pivot or lock pins or trunnions to be withdrawn from the wedge portions 3U of the slots 28 and enter the upper ends of the vertical portion 29 thereof, after which the cover may be lifted to 'bring the lower ends -of the slots 28 into engagement with the pins or trunnions. When so positionedthe cover may be swung either to the right or left, as may be desired.

When the cap or closure is locked onto the neck of the can, the handle 38 is disposed at an angle tothe axes of the lock pins or trunnions, as clearly shown vin Fig. l, and in this position the said handle is also at a slight angle to the handle 2l on the top or shoulder wall Il. However, when the cap or cover is rotated to bring the lock pins or trunnions in line with or into any part of the vertical portions 29 of the slots 28, the handle 37 will be parallel with the handle 2i and also with the lock pins or trunnions.

By light dotted lines, indicated at 4l, Fig. 1, I have shown the cap or closure in open position at the left of the neck; and while the contents of the can can be poured in this manner, the preferable position of the cap or cover 1s indicated by the heavy dotted line 42 in said figure, in which open condition the cap assumes a lower position as well as a more extended position than when swung to the left.

When the cover is swung to the right, as indicated by the heavy dotted lines 42, that is, when in its lower vand more extended open position,

the handle 37 of the cap or closure will be positioned above the handle 2l on the `body of the can and thus, during the act of pouring, the flange, shown at the bottom of the can in Fig. 6, may be taken hold of with one hand, while both handles 2| and 3T may be grasped with the other hand, thus facilitating the act of pouring out the contents and preventing any wiggling or shaking movement of the can; in fact, the cover will be retained in a. permanent position. If desired, the handle of the cap or closure only need be taken hold of, and with proper care so as to prevent swinging movement of the can while holding the cover, no diiculty will be experienced in pouring out the contents of the can. This is also true when pouring out the contents of the can by grasping the handle when in the position shown by dotted lines 4I in Fig. l.

Due to the fact that the neck is eccentrically mounted on the body of the can, less liability of spilling any of the contents while pouring the same will exist when the cap or closur-e is swung to the 'right than when swung `to the left, as viewed in Fig. l.

It will be apparent that, although the handle 3'.' trends transversely at an angle to the plane in which the lock pins or trunnions are arranged when the vcap or cover is closed, this handle will assume a position parallel with the handle 2l on the body of the can when the cap or closure is swung to the right, thus making it exceedingly convenient to grasp both handles during the act of pouring out the contents of the can.

Cans of this kind being invariably carried on elevated portions of a truck body. must be lifted from such position in order to carry the same to distant receptacles or .storage tanks. Oftentimes the handle or cover is out of reach when the delivery man is standing on the ground adjacent the truck, but the handle V2l on the body portion of the can is within reach. It is simple matter to grasp this handle when standing on the ground and, where necessary, tilt the can so as to lift it above ledges usually provided on the truck tc prevent the cans falling oi. By pulling the can over the ledge, the flange at the bottom of the can and the handle 2l may be grasped untii the can has been lowered to the ground. After this the can can be carried to the place of clelivery lby means ofsaid handle, but as this is so positioned on the can that the can will tilt considerably while carrying the same, the delivery man will necessarily be subjected to inconvenience. At such times therefore it is of advantage to grasp the handle 3l. Full weight of the can and its contents will then be carried by the lock pins and trunnions, and the can will be conveyed to its point of delivery in a substantially vertical manner, making it convenient to carry the same and eliminating the possibility of spilling any of the contents while so doing, especially since assurance will be had that the cap or closure is properly locked and will so remain.
