Bromma, Sweden Filed July 26, 1962, Ser. No. 212,522 Claims priority, application Sweden Aug. 1, 1961 4 Claims. (Cl. 220-20) The invention relates to transport-containers for the transport of laundry-goods from a washing machine into a 'centrifugeor hydroextractor of the kind referred to as constructed for use in laundries. v
' In such machines it is desirable toprovide means which will facilitate the proper loading of the machine basket with clothes or other material to be centrifuged and for enabling the material to be rapidly discharged when the centrifuging operation is complete. It is also desirable that the discharge arrangements shall be such as to obviate any possibility of damage to the material.
It is further desirable to provide containers which upon discharging can be stored within a minimum of space and be comfortably stored upon their loading with laundry-goods, so that the centrifuging-operation of the laundry-goods can take place at an order of timing convenient for the manner of operation of the centrifuge, which is of particular importance in industrial laundries, where a large number of containers is required.
The present invention has for its object to provide a transport-container possessing the desirable features above mentioned.
In the accompanying drawings:
FIG. 1 shows a transport-plate in axial section;
FIG. 2 shows in the same way a cylindrical mantle to be combined with the transport-plate;
FIG. 3 shows the transport-plate in plan-View and smaller scale;
FIG. 4 is a plan-view of the cylindrical mantle on smaller scale;
FIG. 5 shows in side-view and partial section a liftinghook intended for transport of the plates according to the invention;
FIG. 6 shows a plurality of transport-plates in vertical section piled on a wagon;
FIG. 7 is a perspective view of the same plate-pile and wagon combined with the mantle shown in FIGS. 2 and 4 and placed close to a washing-machine;
FIG. 8 shows in perspective the wagon with the laundry-goods ready loaded, with the mantle in hoisted position;
FIG. 9 is a perspective View of a scaffolding for the storage of loaded transport-plates, a loaded plate being shown deposited in one of the scaffolding-compartments;
FIG. 10 is an axial section of the upper part of the boss-portion of a plate as well as of a part of a mantle placed thereonto, the lifting-hook shown in FIG. 5 being shown in engagement with the mantle and FIG. 11 is a partial section through a centrifuge-basket and a loaded transport-plate inserted thereinto.
According to the invention the transport-container consists of a circular disc or plate 10 principally of the shape as shown in FIG. 1. The peripheral portion 11 of the plate is slightly bent upwardly and forms a brim. The plate is integral with a central conical boss-portion 12, which is sleeve-shaped and is upwardly directed and formed such, that it can accommodate a center-tap 13 of a perforated basket 14 of a washing-centrifuge, as shown in FIG. 11. The plate 10 as such is fitted according to the bottom 15 ofthe basket 14. All parts of the plate and the boss-portion 12 are conical and are concentric to permit a plurality of plates that can be piled upwards slightly conically tapering mantle ls, as shownv in FIGS. 2 and 4. The mantle: is of such a diameter, that it encloses the peripherical edge. of the plate and rests on the plate by means of ledges. As shown in FIG. 7, where the mantle 18 is arranged on the upper most plate of the pile 16, the laundry-goods from a wash ing machine 19, can be directly conveyed into the mantle and be formed by said mantle during the loading to a plate which maintains its shape after the mantle has been removed, 'as shown in FIG. 8. In order .to obtain a more even distributionv of the laundry-goods inside the mantle, said mantle is provided with radially inward-directed blades 20, the free lower and inner edges of which correspond to the shape of the plate and bear against the latter and the boss-portion 12 and constitute the above-rnentioned ledges. At their upper central part the blades are connected with a cylindrical sleeve 21, in the upper part of which is provided a hollow-disc 22 having a central aperture 23. For the lifting of the mantle from the loaded plate a lifting-hook 24, shown in FIG. 5, is introduced through the aperture 23, the gripmeans 25 of the hook engaging with the under-side of the disc 22 (FIG. 10).
In the loading-position of the mantle 18 on the plates,
the blades 20 divide the space inside the mantle into a number of sectors, each of which is filled with laundrygoods. The sleeve 21 of the mantle encloses herebyas shown in FIG. 10the upper part of the boss-portion 12 of the plate, which towards the top, similar as in the mantle-sleeve, is provided with inward-directed stop surfaces forming engaging-points for the grip-means 25 of the lifting-hook 24. Said stop surfaces are constituted by the under-side 26 of a ring 27 fitted in the upper part of the boss-portion 12, said under-side 26 being connected with a downwardly extending cylindrical surface 28 (FIG. 1), serving as stop for the grip-means 25.
The above-mentioned lifting-hook as shown in FIG. 5, is formed such, that the mantle 18 and the plates 10 can be lifted successively from the wagon 17. The liftinghook is provided with a suspending-loop 24 arranged on a vertical bolt 30, the lower end ofwhich supports an upwards conically tapered wedge 31. When the bolt is elevated during the lifting-movement, the wedge will contact the grip-means 25 thereby pressing them radially outwards, said grip-means being pivoting about pivots 32, inserted in a yoke 33, which is slidable along the bolt 3%. From the yoke there extends downwardly a guide-sleeve 34 for the bolt 30, which sleeve can also serve as a stop for the limitation of the upwards movement of the wedge 31. In FIG. 5 there is shown the lifting-hook in position for the lifting of the upper-most plate of a plate-pile.
In FIG. 9 there is shown a scaffolding 35 consisting of three posts, namely one back post 36 and two forward posts 37, said posts being inter-connected by a number of horse-shoe shaped rails 38. The leg-ends of the rails, which are connected to the posts 37, are straight and arranged at a somewhat greater distance from each other than the diameter of the plate. The portion of the rail arranged at the post 36 follows a circular arc corresponding to the principal edge of the plate. The rails form superposed compartments in the scaffolding for receiving During the loading,
plates loaded with laundry-goods. A loaded plate 39 hoisted in a' device 40 can be inserted between the posts 37 into one of the compartments for storage. According to the figure, the plate 39 is shown deposited in the flower-most compartment. As the washing-centrifuge is emptied, the plates are transported from the scaffolding 35 and inserted into the centrifuge.
The plate 39 is shown in FIG. 11 inserted in the basket 14 of the centrifuge, being provided with a lockable cover 41 for the retention of the laundry-goods during the operation of the centrifuge.

1. A container adapted for the transport of laundry from a washing machine, to a centrifuge, said container comprising a-plate including a central frusto-conical boss, said plate including a frusto-conical portion extending away from the boss, said boss narrowing in a direction away from said portion of said plate while the latter diverges in a direction away from the boss,-said plate including a peripheral portion on the frusto-conical portion, also of frusto-conical shape,'and extending away from the frusto-conical portion in the same direction as the central boss while diverging in said direction, said boss and -frusto-conical portions being concentric to permit stacking of the plates one on top of the other, said container further comprising a mantle adapted for resting on said plate and including a bounding wall and inwardly directed radial blades having a free edge corresponding to the outline of the boss and said portions of said plate whereby the mantle rests with the free edges of the blades on the plate while the wall encloses the plate, said mantle including an upper cylindrical sleeve connected to said blades encircling the boss of the plate on which the mantle rests, said boss and sleeve being provided with openings which are in substantial alignment with the mantle resting on the plate, said boss and sleeve including outwardly directed portions bounding the opening to permit engagement thereof for respectively lifting the boss and sleeve. 7
2. A container as claimed in claim 1 comprising a ring in said boss constituting said outwardly directed portion therefor and provided with said opening.
3. A container as claimed in 1 comprising a disc in said mantle constituting said outwardly directed portion therefor and provided with said opening.
4. A container as claimed in claim 1, wherein said wall of the mantle is cylindrical.
