This invention is a novel garbage receptacle of the class adapted for kitchen use and tobe located handy for ready and frequent opening and closing, attachable forexamplef to, and detachable from, asink, table, cabinet or the like.

The general objects of the invention are to aiford a garbage receptacle of the class referred to which will be handy,` accessiblek and easily operated, small in bulk but expansible with increase of contents, and adaptable to ready emptying and cleaning. A particular object is to afford an article of the kind referred to which is portable, and adapted to be hung or mounted in a convenientlocation, and which in use is readily opened and closed for th-e reception of successive incrementsof garbage; d

A further Objectis to affordV a structure and mechanism of garbage receptacle which will permit quick and wide openingfthereof to'present a substantially horizontal receiving mouth, followed by a quick and tightclosing of the device. Other and further objects and advantages of the present invention Willv be explained in the hereinafter following description A'of an illustrative embodiment thereof or Will be apparent to those conversant with thesubject.

To the attainmentk of such objects and advantages the present invention-consists in the novel garbage receptacle and the novel features construction and operation herein illustrated or described. v

In the accompanying drawing Figure 1 is a perspective view of a garbage receptacle embodying the present invention, shown 'in full lines in its open positiony and in dotted lines adjusted to its normal or closed position.

Fig. 2 on a small scale is a right elevation view of the same receptacle, but limited to the mechanical fittings, the sack or bag being omitted; the same indicated as removably mounted upon the side or apron of a table, beneath the overhang, the receptacle show nclosed-ln full lines and open in dotted lines. l l

Fig. 3, on an enlarged scale, is a vertical section looking from the right, showing the disposition of the mouth of the bag .or sack when in closed position.

Fig. 4,is a perspective View of a convenient form of hook plate attachable to a table and from which theureceptacle hereof may be hung as indicated in Fig.- 2.

Fig. is a face view of a blank of rubber, fabric or other flexible material from which the bag or sack of Figs.` land zmaybe produced. l

:Referring tothe illustrated detailsof an example of the present invention, the receiving element consists of a depending sack or bag I0 shownin its wide open position in Fig. 1 but closed in Fig. 3 and in thedotted lines in Fig. 1; this sack preferably composed of flexible Waterproof material such as rubber, rubberized cloth, or other sheet material, which should also be impermeable to odors and vapors and is strong enough to securely hold a quantity of garbage in wet condition, and even waste liquids. In some casesthe sack might be constructed' of a suitable strong impervious paper, having the advantagethat it may be discarded and replaced with each use. Abag of rubber or rubberized material may be readily cleaned, and turned inside out for the purpose, the bag being readily detachable from the mechanical fittings as will be described.

The form of sack or bag which is preferred has a square upper opening or mouth, shown Widely opened inv Fig. 1, andthe bag is shown as consisting of a front wall II with opposite rear Wall I2 and side walls I3. 'Ihe front and rear walls are turned over and secured or stitched at I4` to form looped tabs 0r hems for the mounting of the bag upon the mechanism. The bag so described may be cheaply manufactured, for example from a sheet material blank of a shape corresponding with Fig. 1; or a modified form such as indicated in Fig. 5. When constructed of rubber the different parts of the bag or sack may be vulcanized together, or the entire sack may be molded or produced in one piece without seams.

The sack I0 is shown mounted in a readily detachable manner upon a pair of outstanding frame parts or rods I1 and I8 receiving respectively the front and rear hems or loops I4 of the sack. As `will be clear from Fig. l, the sack is merely threaded on to the rods and pulledinto place where it remains securely with the aid of slight enlargements or rings at the outer ends of the rods, over which the looped sections of the sack may be passed for the removal of the filled sack from the mechanism. By this arrangement of opposite carrying rods I'l and I8, outstanding from the mechanism to be described, the bag may be widely opened for the reception of material or may have its mouth snugly closed by the approach and overlap of the rods I1 and I8, as best seen in Fig. 3, the sides I3 of the sack collapsing inwardly, and the closed sack being substantially sealed against the outlet of vapors, by the movement of one of the frame rods to a position over the other as seen in Fig. 3.

, permit `the remo-val of the mechanism from the The mechanism by which the sack opening and closing rods I1 and I8 are mounted and moved will now be described. The portable attachment as a whole is carried on a iixed back plate I9 preferably consisting of a narrow vertical channel, and which like the other mechanical parts is preferably composed of a light material as aluminum alloy. To receive the back plate I9 there is shown a permanent plate' 2e having an inturned hook 2| at its upper end. and having side flanges to receive between them the flanges of the channel plate I9. The hook plate 20 is shown in Fig. 2'.

as permanently attached to the apron or vertical board 22 of a kitchen table, below the table over-r hang, so that when collapsed or closed the entire mechanism and sack are accommodated beneath the table overhang. To engage'rearwardly with the hook 2I of the hook plate 20 the channelled back plate I9 of the mechanism is provided with a top hook 23. The entire mechanism is thus held snugly against any displacement, except that its lower end may be tilted forwardly when desired, to

a similar lever 25,. These levers when open'` takeAV oppositely inclined positions as seen in Figi. l, but when yclosed assume substantially vertical positions. Each of 'the levers' is preferably a channel, and the lever 24 is somewhat narrower than 25 so that whenthe mechanism is closed the channelled lever 25 and the channelled back plate, I9enclose 32 onthe arm 21. The lever 25 and arm 21.`rnay` levers 24 and 25fmaybe as follows. These .levers are pivoted to each other at 25. A swinging arm 21 extends vfrom apivot .2,3 on thebak platen flanges to a pivot 29 on the lever 24. The linkage is completed Aby a channelled link 3i) extending from a pivot 3| onthe carrying lever 25 to a pivot remain :noproximatelyA parallel as alsothe lever 24- and the link 30,.' affording a parallelogram motion, but as will be later described a slight departure therefrom may in some cases be desirable.

It will benoted that in being adjusted from open to closed position. the rods I1 andv I8 and the sackl are lifted from alower to a higher level. Thishas the advantage that when the device is unlatched,

l as will be described, gravity affords aquickwide openinglof these-ck without further manual atten, tion.' This operation issecured by the described linkage in combination with a further. arm 34 extending `from the upper end of lever 24 to an axle 35 extending through the flanges of the back plate I9. Y.This arm 34 andaxle 35 are conveniently prof duced by vextending the .carrying rod I1. to the right,Y through and beyond the flanges ofthe lever 24,thence bending it rearwardly as the arm 34, and thence bending it leftwardlly as theaxle 35. When closed the rod I1 isreceived in the notches 36'formedgin the iianges ofthe lever 25, as shown in 2 and in dotted lines in Fig. 1. l

, ,After` the mechanism Vhas been let` down to the open position it inayber'readilymanually, closed by merely pressing inwardly and upwardly upon the lever 25 or the rod I8. When in fully closed position the mechanism is preferably latched there by means of a gravity latch 31 pivoted near the top end of the back plate I9 and engaging in front of the top end of the carrying lever 25. When properly balanced a mere lifting of the latch 31 causes the forward and downward swinging of the parts and the opening of the sack.

In use, the-latch need merelybe touched by the hand or by a dish to be emptied. ,As the sack is lowered to its open position gravity assists its wide opening, and the dish may then be scraped clear and emptied into the sack, whereupon the sack may be-closed by a push of the hand or dish, affordingthe sanitary closing as shown in Fig. 3. When the sack is suiciently full it need only be slipped from the rods manually. It may have side straps or handles for carrying it, and at its bottom a strap or handle for emptying it into an outside or larger receptacle or other vconvenient place of disposal.

To take the opening impact a stop is provided for the opening movement. Thisis shown as an inclined extension 21a of the anges of the arm 21, these lianges contactingagainst thev back plate I9 when the sack is wide open, as shown in Fig. 1. However7 the impact of this stop may be dispensed with by any cushioning means, or the linkage can be modified or rendered non-parallel so that while gravityinitially'assists the 'opening of thebag it may oppose the nal opening movement, thus preventing impact.A Abalanced action'results,'reliev ing the strain on the 'sack' and permitting the use o'fpa'persacks."'

To assure the inward bendingv ofthe sack sides I3 with the closing ofthe sack each side maybe provided'with a' pair of hinged -stripswhich bend inwardly during the closing movement.

While various `arrangements of levers, links and arms may be 'devised tofgiv'e the described movements, the particular linkage illustrated is simple and satisiactory, 'and"may be redescriloed as fol` lows. The rear sack'rod' `I1- is mounted at the h'igher 'endfof thfcarrier'foi" lever'24. This lever takes its inclined position when the sack is open it rises toa vertical'fposition when the sack is closed'.-4 These movements'of lever 24 are produced bythe arms 34"f'and 21.' The upper arm 34 is shorter thanthe lowerv arm`2-1, andthe spacing of the pivots 28 and 35 is such'that when'added to the vlengthfof th'e arm 34-the s'uin will equal the length of the arm 21 plus the portion of thele'ver 24v whichvextends betweenfthev pivots I1 and 29. This portion'of thel lever -24 and the arm 34 are shown of substantially-thesame length, while the arm 21 is substantiallyfthesame length as the spacing between the fulcrums of the arms 34 and 21. This simple linkage completely 'controls the desired movements of the lever 24. v The lever 25, tol secure thedesire'd wide opening is pivoted at 26 to theextreme lower end of thedlever v24. vThe extension oi the lever 25 below said pivot is connected by the link 30 with the arm 21.-v Thisfgcompletes a quadrilateral, which may be approximately a parallelogram, so that in the openingand closing movements the carrier levers 24 and 25.form a V, .taking opposite slants whichchange pjrogressivelyvto Avertical until, with the complete 'closing of the mechan-ism both levers stand. vertical, o'r substantially so, as well as the controllingarms land link.

In a somewhat different aspect the arm 34 contrqis'the upward endrearwarfd .swinging of the rear sack rod I1, while the movements of the front rod I8 on the lever 25 are controlled by both of the arms 34 and 21 through the levers 24 and 25 and the intermediate connection or link 3B. The entire linkage or mechanism it will be noted is at one side only of the sack, namely the right hand side, the sack rods outstanding leftwardly therefrom, and their left ends being free for the removal and replacement of the sack.

There has thus been described a garbage receptacle which embodies the principles and attains the advantages of the present invention; and in part this application is a continuation of my prior application Serial No. 697,631, filed November 11, 1933.
