GLOSABLE CA ET FOR T COLLECTION AND SAFE STORAGE OF SOILED LINEN Filed Feb. 5. 1962 4 Sheets-Sheet 4 INVENTORS DONALD R. HUGHES MERVYN L. OLIVIER ATTORNEYS United States Patent O CLOSABLE CABINET FOR THE COLLECTION AND l This invention relates to a closable cabinet for the collection and safe storage of soiled linen, more particularly for use in hospitals and other large institutions where a large a'mount of soiled linen has to be dealt with each day. f

Objects of the invention are to provide a cabinet for this purpose which permits -soiled linen to be easily deposited through a closable Aopening in its top end into a Asepa-rate removable lockable container within the cabinet and thus prevent theft and exposure of the soiled linen to flies and air currents which might spre-ad infection.

According to the invention, a cabinet for lthe' collection and storage of soiled linen includes; a frame enclosed by an outer casing; an inner removable closable and lockable container within the outer casing; a closable filling opening in the top end of the cabinet through which to deposit vsoiled linen into the inne-r container; means to close and -lock the inner container'within the cabinet before it can be removed from the cabinet; and foot-operated shaking down means adapted to compact the soiled linen in the `inner container.A The said shaking down means may be 'erably of bag-like form made from flexible sheet material.

The locking of this inner containertis arranged to take rplace before it can be removed from the cabinet by way of alockable door opening in a side wall of the cabinet.

The closure means coacting with the top filling open- I'ing is so arranged that, although soiled linen can be readily 4 deposited in the cabinet and into the inner container it cannot vthereafter be withdrawn through the filling openving,/which arrangement prevents theft of articles once they have been deposited in the cabinet. The filling opening may optionally include disinfectant means to provide 'a decontamination function.

To achieve ythis object, the closu-re means is in the form vof avhorizontally disposed inner drum member mounted within an outer similarly shaped casing for rotary movement with respect to such outer casing about its horizontal axis. The inner drum member is rotatably mounted by means of stub axles at its ends which a-re journalled. in

'bearings provided in or outside of the end walls of the outer casing. In'one arrangement, one of these stub axles projects through its bearing and an actuating lever arm fixed to such outer end, isv linked by a connecting rod to the aforementioned foot-operated shaking-down means located at the' bottom end'of the cabinet. f

Alternatively, one of the stub axles projects through its lbearing and a toothed sprocket wheel keyed to such outer ice Patented May 3, 1966 The inner drum member may rotate about its axis to bring its opening into a first position of alignment with the top opening of the outer casing yto enable a batch of soiled linen articles to be deposited therein.

Subsequently the drum is rotated an angular distance suliicient to bring its opening into a second position of alignment with the bottom opening of the outer casing, whereupon the contents are free to fall out into the inner bag-like container. In this position, the top opening of the outer casing is of course closed so that the cabinet is sealed. Preferably rubber `buffers are associated With the ends of the transverse pivot shaft to eliminate undue noise and shock during the shake-down operation.

The cabinet of the present invention, is an improvement over existing cabinets or containers for soiled linen used in hospitals, in that it enables soiled linen to be deposited easily and immediately at the point where it isv taken out of use with complete security and safety (providing a proper system of control of the separate keys to the ca-binet and to the inner bag-like containers is instituted) and Without exposing the linen to ilies and air currents, which may spread infection.

The shaking-down device, enables the maximum quantity of linen to be stored in the minimum space. Furthermore, the bag-like containers, While being light and readily portable for the conveyance of both soiled and clean linen between hospitals and laundries, are also easily cleaned and disinfected. l

A further advantage is that the design of the cabinet and linen which is a serious problem in hospitals throughout end is connected by a chain to a chain wheel or the equiva- :lent operated by a foot-pedal located at the bottom end of the cabinet. Other and further alternative methods may be utilized as will be apparent to those skilled in the art. For example, a pedal-operated rack coacting with apin-v ion on a stub axle ofthe drum member may be used.

FIGURE 6 is a cut-away pictorial view of the lower part of the cabinet of FIGURE 5 as viewed from the opposite side Ibut showing the bag in position;

FIGURE 7 is a fragmentary pictorial View showing the FIGURE l0 is an enlarged fragmentarycross-sectionalv view showing the bag closing members at the commencement of the closing position with the bag removed;

FIGURE l1 is a similar view showing the bag closing members partly closed;

FIGURE 12 is a similar view showing the bag closing members in their fully closed and locked position; and

FIGURE 13 is a view similar to that of FIGURE l2, but showing the simultaneous unlocking of the door catch when the bag closing members are in their fully closed and locked position.

Referring to the drawings, reference 1 denotes the cabinet of rectangular form mounted on castors 2. A handle 5 is provided for wheeling the cabinet along on the castors 2 as required. Provided on the top end of the cabinet 1, is the rotatably mounted inner drum mem- 'ber 6 located inside of the outer xed casing 7, having a top opening 8 and a bottom opening 9. The inner drum member 6 has a single opening 10- through which the soiled linen is inserted when this opening coincides with top opening 8 of the outer casing 7 as shown in FIGURE 3. Each of the openings 8, 9, and 10 preferably have an arc length ywhich does not exceed 90. The inner drum member 6 is provided on its end plates with stub axles- 11 which project through apertures in the end plates of the outer casing 7 and ar'e journalled in bearings 12 supl ported from the top end of the cabinet fra-me as shown in FIGURES 3 and 5.

The shaking down means at the bottom of the cabinet f is made up of two at plate members 13 and 14 iwhich are hingedly connected along their meeting edges to a transverse pivot shaft 15, the ends of which are slidably located on vertical guiding pins 16 fixed to the cabinet frame. To operate this device, a foot pedal 38 is keyed to a pivot shaft 18 to which two arms 39 are fixed, whichv arms extend beneath the plate members 13 and 14 and coact with short downwardly directed roller extensions 20 fixedY to the pivot shaft 15. Downward pressure on the foot pedal 38 will then raise the pivot shaft 15 so that the plates 13 and 14 assume an inverted V-formation as more clearly indicated in FIGURE 6. On release of the foot pedal 3S, the plates 13 and 14 drop back to their inoperative positions and in doing so give the bottomof a bag 21, supported thereon, a positive shock which compacts any soiled linen previously deposited therein.

As shown in FIGURE 8, the bag 21 is square in crosssectionand the top edges of two opposite sides ofits mouth opening are fixed to closing members 22 and 23 of angle-section which are provided at their ends with supporting projections 24 by means of which the bag is supported in suitable socket fittings provided inside of vthe cabinet. When the bag is closed, the two bullet nosed pins 25 on the closing member 22 engage intubular receivers 26 on the closing member 23 and a key opera-ted lock 27 coacts with a corresponding catch element in the closing member 23. Whenv the lbag 21 is inserted in the cabinet the projections 24 on one closing member are engaged in a pair of front sockets 45 at one side of the cabinet while the projections 24 on the other closing member are engaged in a pair of rear sockets 44 carried by a pair of arms 40.

Access to the interior of the cabinet is provided by a hingedly mounted door 32 on the front side thereof.

Rotary movement of the inner drum member 6 is now effected by means of chain 33 passing around a chain sprocket 34 keyed to a stub shaft 11, and a chain wheel 35 which is arranged to be partially rotated by a foot vpedal 36 against the action of a tension spring 37. Operation of the shaking down mechanism is effected by. means of the separate foot pedal 38 and arms 39, which coact with the shaft 15. In an alternative arrangement the shaft 15 may be connected by a link 31 to an arm 30 keyed to one of the stub axles 11, so that operation of the inner drum member 6 will simultaneously cause operation of the shaking down mechanism. This modication is shown in chain-dotted outline in FIGURE 2.

Opening and closing of a 'bag while in the cabinet is effected by the two vertical spaced bag-supporting arms 4 40,1ocated within the cabinet adjacent to itsrear side which arms are pivotally mounted as regards their bottom ends by being. keyed to a transverse pivotally mounted shaft41 arranged to be oscillated -by an external hand lever 42.

The top ends of the arms 40 are connected by a cross bracing 43 and each of such ends is provided with a bagsupporting socket 44. In addition, these top ends are bent inwardly ata small angle and are arranged to be a few inches higher than a second pair of bag-supporting sockets 45 pivotally attached to bracket plates 46v projecting inwardly from the door opening. These sockets 44 and 45 are arranged to receive the projections 24 of the two bag closing members 22 and 23.

To insert a bag, the arms 40 are 'brought to the forward position shown in FIGURE 7 and the projections 24 are inserted in the sockets 44 and'45. The door 32 is now vclosed and by means of the .hand lever 42, the arms 40 are pivoted rearwardly to open the mouth of the bag. When the door 32 is closed, a 4springactuated pivotally mounted latch 4.7 on the inside of the free edge thereof, engages beneath a 4stop edge 48 of the door frame so as thereby to lock `the door 32 in the closed position. The door can thereafter only be opened when the arms 40 are brought Vforward so that a lstriker rod 491tixed to one of them engages with a short lever extension 50 of the latch 47 so as to cause it to pivot downwardly against the action of its leaf spring v51v vso as to release it. 'In this position, the arms 40 will have caused the -lock 27 to have rengaged with its counterparty on the closing member 23 of the bag.

To facilitate emptying of a bag, an'articul-ated frame device comprising twor shallow U-shaped parts 52 hingedly attached at their ends to a central cross bar 53 having aholedlug or eye 54' fixed to. it midway between its ends, is arranged to be locatedin the 'bottom ofi-the bag as shown in FIGURE V8. The lug or eye 54 is arranged to pass through a hole in ythe bag bottom so that a suspension 'ring `S5engaging therewith is outside of the bag. Stop lugs y56 are provided on :the endsrof-parts 52 arranged to permit free pivoting movement forthe shaking down operation butto retain these lparts in the samek planefwhen the bag is suspendedin the :inverted position by the ring 55. The Itwo parts 52 `are preferably made from tubular stock.

Reference is -nciwrnade` to FIGURES -5 yand Sa showing how decontamination -of t-he` inner drum member 6 is effected automatically each time the pedal 36 is 'depressed. To achieve: this result, one `end of the inner drum 6 is provided with a bearing 57 which coacts with -a hollow journal pin l58 `suitably held in a holder rblock 59 supported from a `frame member 60 .of the cabinet. A pipe or tube 61 is connected by yone end to the outer end o-f the journal pin 58,'i-while its other end is connected to a small pump 62 'arranged fork intermittent operation by means of a cam 63 keyedito 'the` pivot pin 64 on which the foot pedal -36 .is mounted -or tixed tothe chain wheel 35. The pump `62 is connected to a reservoir165 containing a suitable liquid disinfectant by a pipe or tube 66.

Asimple bacterial filter for the mouth of the |bag consisting -of a strip 67 of oil-impregnated felt, foam plastic or the. like, .is arranged to be .located above the Yt-wo tubular receivers 26 of the closing member 23 as shown in FIG- UR-E 8. Handles 68 `are attached to the outsides of the closing members 22 and 23 vto facilitate handling 'of 'a bag.

FIGURES 10, 11, 12 and 13 show more clear-1y how the bag closing members 22and 23 are closed together and locked by the key-operated lock 27 which is. provided with -a locking latch 169 biassed '.bya spring `70 .towardsvits 'i closed position so .that when fthe two bag closing members 22 and 23 vfaire in their` fully closed and locked position vas shown in -FIGURE 12, the latch 69 will automatically be projected into the locking 4aperture .71 provided in the bag :closiugmember` 23 which when closed is located on the inside of the bag closing member 22.

Reference 72 indicates Ithe two inwardly folding ilat hinge elements connecting t-he bag closing members 22 and 23, to which elements the top end regions of the two Vsides of the bag 21 ,are attached such as by providing a tunnel 73 in such top end regions to receive the hinge elements 72 (see FIGURE 8). The hinge elements 72 are preferably detachably securable to the bag closing members Z2 and Z3 such as by arranging for the end hinge pins 74-to be removable. The two other opposing sides of the bag 21 are also preferably detachably securable to the downwardly extending flanges of such bag closing members 22 and =23, such as -by clamping the ltop beaded edges thereof to these ilanges by cla-mping plates and the use of bolts or studs, and/or the pins 25 and their tubular receivers or sockets 26, which may have screw-threaded ends for this pu-rpose. In this way the bag 21 is readily removable for replacement purposes such .as when damaged or worn out. 'The strip of impregnated'felt 67 constitu-ting the bacterial fil-ter is located between the tubular receivers -26 and the underside of Ithe top ange of the bag closing member 23.

FIGURE 13 shows clearly how, when the Itwo bag closing members 22 land y213 are in their fully closed and locked positions, the end of the striker rod 49 attached to an arm 40, makes contact with the lever extension 50 of the door latch so as to open it against t-he action of its curved leaf spring I51. Thereafter the door 32 can be opened to remove Ithe locked bag 2-1, on release of the bolts 75 by the handle 76.
