FLUID RECEPTCLE.

Application filed April 14;, 1320, Serial No. 373,759.

To all 'ui/tom it may concern: y

Be it known that l, FRANK Crnitriirvr, citizen of the United States, residing at Fort 'li/Vayne, in the county of Billen and 51 f'ltate of lndiana, have invented new and useful lmprovenients in Fluid Receptacles, of which the following is a specification.

rlhe invention relates to fluid receptacles and particularly to receptacles adapted for lense in the shipment of milk, cream and various other forms of fluids and materials. j lhe object of the invention is to provide a receptacle which `is sanitary, fluid tight, durablel and economical of manufacture and ,l maintenance, and which may be stacked one upon another with safety dnother object is` to provide a receptacle which shall automatically vent itself inthe event of the accumulation of gas within it` 20V asin the. icase of sour Creane-and -thereby prevent injury-.to the can or lossof the coni tents and injury to theperson who may open the same.

Another object isjto provide such recep- `2o tacle with a fluid tight cover and with novel means for securing and sealing the cover on its seat, the said means also being capable, y when operated, to unseat the cover j @their objects and advantageswill be `re- 311i ferred to hereinafter.

ln the accompanying drawings l have il lustrated one manner in which the invention may be carried out in practice and in which` i V Figure 1 is an elevational view of a re ceptacle constructed in accordance with the invention; Figure 2 a plan view of the same; `Figure 3 is a fractional elevational view ofthe same partly in section; Figure to elA a plan view ofone of the clamping levers; Figure 5 a longitudinal. cross-section Vof thelever, and Figure 6 a side view of one of the handles.`

,p lh'eferring to the drawings, the receptacle. le comprises a cylindrical body 10 formed,

tom'12, preferably curved to present a con-jy 5d cave surface facing upwardly and substan` tially continuouswith thev wall of the re ceptacle, is suitably secured to said wall above ring,r 11.. The opposite end of the body is open to form the mouth and a ringyl?) to is suitablysecured to the exterior side of the sufficiently spaced apart to receive and piv otally support between them a handle 16 wall of. the body adjacent said mouth, the upper edge 14; of which ring forms a seat for the cover.` Suitable brackets 15 are secured in pairs to diametrically opposite sides of ring 13, the brackets of eachpair being having sufficient Weight to normally hang downwardly but which may be rotated. upwardly through 90. rlhe end of each arm 17 of each handle adjacent the pivotal point of the same is squared at the outer corner so that when the handle is elevated on its pivot the squared ends of the arms will abut the face of ring 13 and prevent further .upward movement of the handle.

Suitable brackets 18 are suitably secured in pairs to the ring 13 at diametrically op posite points and adjacent the upper edge of the rino; and, preferably, intermediate the handles. Each pair of brackets 18 pivotally support a lever 19. This lever is of peculiar form and comprises a ehannelled member b aving the forward portion of its bottom 20 bent upwardly and rearwardly to forman inclined. cleat 21, the function of which will. be explained hereafter rljhe side walls of the lever are provided with corresponding' earns 22 along their upper edges and pivots 23 project laterally from said walls for-v wardly of the cams and are adapted to be inserted in apertures formed in brackets 18. A pair of brackets 24 is suitably secured to the ring `below each pair of brackets 18, the members of each pair being spaced to 90 permit lever `19`to passbetween them and each memberbeing;` provided. with an aperture 25 through which and through apertures 26m the side walls of the lever may be passed` a seal27 by which the lever is sealed in its down or locking position The cover28 is formed with a flat or slightly eoncaved top.y a rin5r29 being suita bly securedto the outer face of the depend` inn' annular flange 30 of the cover and adapted to engage seat 14 on rinn- 13. 1When installed the dependinnflange of the cover below ring1 29 is passedwithin the mouth of the `V receptacle and makes a close fit with the wall thereof. Adjacent its lower end flange is crimped or otherwise shaped to form an annular channel ill-opening toward the wall of the receptacle. When the cover 4is installed on the receptacle body air remains and is confined` in channel 81 and 110 seals the cover to the body so that lio iid wit-hin the body cannot escape around the cover since the liquid cannot pass the air tilled channel. n aperture 32 is termed in flange 30 of the cover at a suitable point below ringQQ which will serve to vent the receptacle when the cover elevttel sulliciently to expose the aperture to atmosphere.

At diametrically oposite sides ot ring' 2li are secured loops 33 which project laterally from the ring. A coiled spring -l is loosely engaged `on each loop 33, the eng: nement being such that the springi has Atroc movement-both circumterentially and lonk tudinallyot the loop. The lower ond 2li. ol each spring is hook-shaped and is adapted to engage under cleat- 21 when the spring drops into the channel of lever i9. rlhe lone'itudinal movement ol the snrinr; on the loop makes possible the passage ot the spring into the channeled lever without accurate alignmentl oli the loop with the lever; that is: the cover may be inserted on the receptacle body without accurately registering the loops with the levers, the springs, within the limits ot' the loops, being slid along the loops until they pass into the channels of the levers.

To install the cove-r on the receptacle body and lock it thereto, the depending` llanos of the'cover is .inserted into the mouth or the the body, the loops with their depending springs being` positioned adjacent the clamp-- fing levers, and the springs are dropped into the channeled levers it they do not pass into saidv channeled levers or' their own accord. The levers are-then roclred upwardly on their pivots. The inclined cleat 21 of each lever, when itl abuts the hook 35 of the spring, causes the same to travel up the incline 'and drop over the edge ot thc 'cleat and engage under the sam-e. The levers are then depressed .into vertical position the springs drawingl the cover down onits seat. A seal their may be attached to leach lever and the brackets 24- and thereby` seal the lcover to the body. Thereafter tor open the receptacle the seals must be broken before the cover ican be removed andv unauthorized openingv ofthe receptacle is thereby guarded against.

To removey the cover both levers are grasped inthe hands and rocked upwardly. rlhe springs move upwardly with the levers and turn on the loops. The cam surfaces on the levers enga-ce the loops and the continuous movement of the levers upwardly pryy off', as it were, the cover, the dist-ance the cover'is-elevatedl being` determined by thedistance upwardly the levers are moved and the Jforce applied to them. It the mevrj ment of the levers upwardly is sudden the cover may be entirely disengaged trom the body,-the springs, at the same time, re`

messen leasinpy their engagement willi the lovers. lilihen the levers have beer. elevated :i short distance above ihr, ilo point the hooks on the springs tend to discnfgae'e from under the cleats and eventually do discnn'agrc and drop out ot the levers whether or no( the levers are moved quickly. .`\io matter how tightly thc cover may bc scaled on the mouth ot thc receptacle body the clamp levers will iu'iseal the Cover and inalrc ii*` linal removal inos easy lo :n.fconiplish.

.ln the event that the contents olt the receptacle give olil a gas, as when cream i contained within it and 'tei-nichts. the gas will accumulate within the receptacle and when its pressure is sulliciont to overcome the tension on springs 3l, the springs will permit the cover to rise to expose vont 32 and permit the gras to escape and thereby prevent the explosion ot the receptacle or the l'ilowiiu;` out ot the cover. Many persons have been injured in the past b v the blowing,r ott oll a milk can cover when attemptingT to remove it 'trom the can body. lily my invention such injury is practically impossible since the receptacle will automatically vent itselt it 'termentation ot the contents of the receptacle occurs.

It will be noted that no part ot the lockinn` mechanism is above the upper surface ot the cover and that since said surface is 'flat or substantially llat. the receptaohas may be stacked one upon another. The body oli the receptacle beingr Cylindrical with no restriction at its mouth the same readily cleaned and may be exposed to sunlight with the assu ance that every portion ot the interior ol the receptacle will be reached by the light rays. The recei'itacle is, therelore, highly sanitary, lt will withstand hard usage and no matter in what position it. may be placed the cover is sealed in thc body so that the contents of the body will not escape.

That l claim is:

l. In a tluid receptacle. a body, a cover for the body, a springT engaged on the cover and depending exterior-ly thereotl a lever pivotally mounted on the body and having a longitudinal channel therein.y an upwardly inclined transverse cleat in the bottom of the channel adapted to releasably engage the lree end ot the spring', and a cam member on the lever adapted to unseat the cover when the lever is operated in one direction.
