GARBAGE-CAN.

Specification of Letters" Patent.

Patented July 13, 1915.

Application filed February 20, 1913. a Serial No. 749,750.

To all whom it may] concern Be it known that I, THOMAS A. KEEN, a

citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Garbage- Cans, of which the following is a specification.

This invention relates to improvements in garbage cans. e

The objects of the invention are. to provide for the secure and positive closure of the can in substantial air-tight relation for the purpose of minimizing decomposition and preventing the escape of odors of garbage and to provide a can which may be discharged with ease and facility, notwithstanding its normally secure and positive closure. J

With the above objects in view the invention consists in a number of novel features of construction and arrangement, among which are the relation between the top and f the body of the can whereby an airtight A preferred embodiment of the invention is illustrated in the accompanying draw ings, wherein:

Figure 1 is a vertical sectional view illustrating a can in which the features of'the invention are incorporated; Fig. 2 isa side elevation of said improved can, with the top thereof in a partly open position and lllllS-r trated partly'in section; Fig. 3 is a fragmentary side elevation illustrating the action of the device which positively retains the top in closed position; Fig. l is a bottom plan view of the can; and Fig. 5is a fragmentary bottom plan view of the top or cover of the can.

Similar characters of reference designate corresponding parts throughout the several views.

The can comprises body 1 which may be 7 of ordinary cylindrical form, a cover 2 to provide a closure for said body, and a bottom 8 which is located at a short distance above the lower edge of the body 1.

The cover 2 includes a depending annular flange a which, when the top is closed, uniformly engages upon anannular ledge or flange 5 circumscribing the upper portion of the body 1. In this way, the cover- 2 provides a substantially air tight closure for the body 1 and the odors of the garbage are prevented from escaping.

The cover 2 is preferably utilized as a container for the disinfectant used to prevent decomposition of the garbage. For thls purpose said cover is provided with a plate 6 arranged within the flange i and defining an internal chamber infectant, c i j v The cover 2 is pivotally supported and 7 for the dis provision is made for the discharge of disinfectant into the can consequent to the pivotal' closing movement of the cover. For

thispurpose, the pivotal support of the,

cover 2 includes a bail 8 which is fixed to said cover at opposite sides thereof, and 1s pivoted as at 9 at opposite sides of the body 1 adjacent the lower end thereof. The upper edge of the can is preferably inclined relatively to the bottom and the flange 5 is arranged in an inclined plane parallel to the plane of the said inclined upper edge. In this way provision is made for suitably spacing the cover, during its pivotal move ments, from the upper edge of the can, as

indicated in Fig. 2.

f Theplatefi is provided with disinfectant discharge openings 10 and may carry cylinchamber 7 and aline with said openings. To

' control the discharge of disinfectant into the can, a valve is employed which is operative said plate to closed position. The plate 12 has openings which, in the open position of drical screens 11 which project into the said plate, register with the openings 10 of the plate 6. The plate 12 is n'ormally closed by a spring 14 which may be conveniently arranged on a stem 15, carried by and projecting rearwardly from said plate. The spring 14: is arranged between the flange 4 and a shoulder 16 of the stem 15. When the cover 12 is moved to closed position, the upper edge portion of the body 1, at the rear side of said body, engages the shoulder 16 and causes a relative rearward movement of the plate 12 against the tension of the spring 14 and-durin such movement, said plate un-' uniform engagement of the flange 4 with the ledge 5 not only promotes the security of the.

closure effected by the cover 2, but also produces an appreciable shock or jar and this shock or jar is instrumental in causing a sufficient quantity of the powdered disinfectant in the chamber 7 to fall through the previously uncovered openings 10 upon the garbage which has been deposited in the can. The screens 11 serve to prevent any lumpy formations of the disinfectant frompassing into the can, and consequently, the disinfectant is discharged into the can in'a finely powdered condition, in which it is-best calculated to serve its purposes and to uniformly attack the mass of garbage. When the cover 2 is opened, the spring 14 moves the plate 12 to close the openings 10 and to prevent loss of the disinfectant in thechamher 7, as well as the undue exposure thereof to the atmosphere. Y

I As previously stated, the cover 2 closes the body 1 in a substantially air-tight manner, and in order that there may be no interference' with the efliciency of the closure thus established, it is preferred to provide for the positive retention of: the cover in closed position- The invention includes simple and effective ;means for this purpose. Such means preferably comprises latch fingers 17 7 arranged adjacent the under face of thebotaforesaid to the body 1, and theother leg ofwhich isriVeted or otherwise secured at its'lup'pe n to t e cove 2 Belo th pivots 9 and in the portions thereof connectin-g said legs, the side bars-ofj'the bail 8 are provided with shoulders 19. The projecting ends of the fingers 17 normally engage the shoulders 19 when the cover. is in closed position, and thereby positively prevent accidentali'novement of said cover from said closed position. When it is desired to open the can, the fingers 17 aremoved from engagement with the shoulders 19 vSaid fin gers are pivotally secured to thebottom 3,

its end opposite the spring 21 isv provided with a head 2 to which the inner ends of the fingers 17 are connected as by pin and slot joints 25. The movement of the slide 22 by the spring 21 is limited by a stop 26 secured to the bottom 3. i

The spring 21, through the agency of the' connections described, holds the fingers 17 normally in position to engage the shoulders 19, Said fingers have suflici'ent resiliency or loose play to yield under the pressure of the bowshaped portions of the side bars of the bail when the cover 2 is moved to closed position, s'ai'd bow-shaped lower end portions thus acting as cams. As soonas the shoulders19 pass beyond said fingers, the latter spring back intotheir normal planes and engage said shoulders, as shown inFig. 3, thus latching or positively retaining the cover in closed position, and insuring of the permanence of the secure engagement of the flange 1 upon the ledge 5. To open the can, the spring 21 is bowed outwardly, thereby moving the slide 22 away from the stop 26 V and causing. a pivotal movement of the fingers 17, whereby they disengage the shoulders 19'. Thereupon the cover 2 may be swung rearwardly, as indicated in Fig. 2.

'rh arran e ent of the bail 8, cover 2, and the bail latching means is, as above stated, useful to secure the efficient discharge of disinfectant into the can and also to provide for asubstantially air-tight closure of the cover. This arrangementserves a further important purpose, in that itenables the canto .be operated to discharge its contents with ease and facility. When the contents of the can ,are to be discharged, the can is lifted from the groundor support,

and during this lifting action, the cover is positively retained in position by the means described. Thereafterithe spring 21 is engaged and; bowed outwardly and the pull on this spring not only disengages the, catch fingers 17 from the bail 8, and' thereby releases the cover, but also starts the can in;

its tilting movement; It will be observed that the pivots. 9, which connect the body 1 and the bail 8 and the hand grip 8 of said bail are located off center. flonsequently,

the can is started in its tiltingmovement to discharge its contents with very little effort.

Matters of specific description herein contained are not intended to put any limitation upon the scope of the appended claims which does not inhere in the language thereof.

Having fully described my invention, I claim:

1. In combination, a can, a cover constructed, when in closed position, to have sealing engagement with said can, a bail carrying the cover and having 'U-shapedside bars pivoted to the can adjacent the lower end thereof, and having shoulders in the bow-shaped portions of said side bars, latch fingers movably mounted under the bottom of the can, and means acting automatically for causing said latch fingers to engage said shoulders when the cover comes into closed position.
