4 Claims. (Cl."226--47) This inventiomrelatesto a machineior filling casings .oipillows and L-similar .-.containers, :with

fibrous materiall-such askapok, etc.

Anobjectof this invention is to providea filling machine comprising ac-i-rcularplatform rotatably mounted .on a shaft, sthe platform, having a plu- ,rality .ofsupports equally spaced around its cir- =l1ll'l-f616110e81nd.p1OVldlIlg vertical Walls against which casingsmfpillowsz-and:thelike mayibesuitably ssupported rfor irotationland to provide con; duitsrorlopenitopeguideichannels on the platform .and leadingdirectlydnto the ;Caslngs to befilled.

Another object .of this invention is atoprovide a -'distributor :comprising 41a 'rzplu rality of radially positioned blades-and:beingmonnted at the upper lh'ousing :aroundithe-rdistributor sand :to provide a coneeshaped ismiember :at the central :portion .:of

the platform so .ithati.,fibrous :material thrown .1up'on the scone willcbemdistrizbuted .idirectly to lithe conduits and into the casings to be filled.

Another object of this invention is dvo iprovide :a hopperzceritrally :lpositioned .inzrelation to the distributor wherebyrmaterial'ifed into the hopper will be "broken'tup byit'he Zdi'stributor .and confined byithe'ihousingsaroundithe distributor and made to follow fdow nwardly intofthe conduits and into the casingsi-to rbezfilled.

Al'lObhEl ObjGCl? of :this invention is to provide a power: drive for the shait whereby centrifugalforc'e will beimparted1to1theifibrous material fed through thehopper an'dwhereby the material will :acquirasufiicient force to enable it to forcibly enter into the casings and to forcibly eject the airthere'from and so that a densely'packed pro'olnot will result, it being immaterialwhether the casings are porous or non-porous because the pressure imparted to the fibrous filling material due'to'the centrifugalfforce can be so controlled as to be more thanisu'fiicient to expel all the air from the casings and to denslypack the casings.

With the above :and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement "of parts will beshownin the-accompanying drawizings and pointed ;out in the rclaims' which form part f this specification.

In the illustrated embodiment of the invention, thenumeral 10 indicates afilling machine ;comprising ,a rotatable .diskeshaped platform-H having ia-plurality of :angulansupports. l2 having converging vertical walls for supporting fabric casings. :Each support .is suitably fixed at its .outer periphery. ;.The platform H is fixed to a vertically mounted shaft M which is suitably supported byrbeanings l5 and rotated by a motor 45. -A cone l-Iis fixed to the upper .face of the rotatable platformdl. At the upper end of the shaittl l'is a distributor lBhaving radially posi- ,-tioned upright vanes l9-equal1y spaced around its .eircumference.

. A stationary housing-sor :casing 20 encloses the platform .II and carries a plurality "of arms 26 which support ian iinverted cup-shaped member :21. The vmember 2-I encloses :the distributor .18 ands-has acentral opening -22 in its upper face. :A hopper 23 is carried by a perforated support '21 The hopper extends into the memberJl-through-the opening 22 .and provideszmeans whereby fibrousffilling material rmay Joe droppedupon the rdistributor. Open top guide channels 24 are formed by angles 28 suitably fixed to the platform II and extend from the cone i! into fabric casings 25 lying in the angular supports I 2. The lower face of the member 2| terminates adjacent the open top guide channels. The vertices of opposite angular supports are diametrically positioned. When the filling material is dropped into the hopper 23, the distributor vanes l9 feed the material radially and the member 2| directs the material downwardly to the rotatable platform I Due to the centrifugal force developed by rotation of the platform H, the fibrous material thrown into the hopper acquires centrifugal force tending to throw it outwardly from the rotatable platform and this force causes the material to be forcibly fed into the casings under great pressure. This pressure forces the entrained air out of the fabric casings 25 and permits dense packing of the fabric casings even though the fabric is made of non-porous material which does not idly and densely.

Figures 6 and '7 show a modified filling machine 35 comprising a rotatable disk-shaped platform 36 carrying an upper casing section 31 and a.

lower casing section 38 which are held in unitary relation by wing nuts 39 threaded upon pivotally mounted bolts 40. The casing sections 31 and 38 are of the same circular cross-section. The interior of the lower casing 38 has a mold section 4!. The interior of the upper casing section 31 has a complementary mold section 42. In the illustration shown the interiors of the mold sections are in the shape of a hexagon and are designed to receive fabric casing such as that used for a hexagon-shaped hassock 43 or the like. Mounted on pivot pins 44 on the upper mold casing section 31 are a plurality of gripping rods 45 having arcuate ends 46. The arcuate ends 46 serve to grip and support the neck portion of the hassock casing 43. Supported on the top of the upper mold section 3! by suitable angle members 48 is a hopper 49.

The platform 36 is mounted on a vertical shaft 50 which is suitably supported by bearings and rotated by a belt 52 from a motor (not shown).

It is to be noted that slots 4'! have been provided in the lower portion of the hopper 49, for the purpose of clearing the arcuate ends 46 of the rods 45 in their upward movement out of the hassock as is the case when a filled hassock is removed and replaced with an empty one.

The filling material is fed into the hopper 49 and enters the hassock casing 43, and, due to the centrifugal force developed by the rotation of the platform 36 the fibrous material fed through the hopper tends to move radially and acquires centrifugal force which throws the material radially outwardly and this force causes the material to be forcibly fed into the hassock casing under pressure. This pressure forces the entrained air out of the casing 43 and permits dense packing of the hassoclz casing.

Figures 8 and 9 show another modified filling machine 55 designed for filling two casings 56 suitably held by angular supports 51 on a rotatable platform 58. The casings are held at diametrically opposite points of the rotatable platform. The platform is supported on a frame 59 and rotated by a shaft 60.

A protective cover, preferably made of wire grill work 6| is positioned horizontally in line with the upper surface of the fioor 62 of the operating room.

It is to be noted that the filling machine disclosed in Figures 8 and 9 is preferably sunk below the fioor level. Supported by angle members 63 is a hopper 64 through which the material is fed downwardly.

Suitably fixed to the revolving platform 58 is a receptacle 65 having two radially extending ducts 66 leading into guide channels 61. The guide channels 61 are secured to the platform by angle irons 68. The neck portions 69 of the easings 56 to be filled are secured by cords 70 pass-- ing around the guide channels 67.

Due to the centrifugal force developed by the rotation of the platform 58 the fibrous material fed into the hopper 64 tends to move radially and. acquires centrifugal force which throws the material radially outwardly into the guide channels and forcibly feeds the material into the casings 56 under pressure. This pressure forces the entrained air out of the fabric casings and permits dense packing of the fabric casings even though the fabric is made of non-porous material.

It is to be noted that due to the substantial quantity of material fed through the hopper, after the central portion of the hassock casing is covered the additional material fed into the casing is fed away from the center of the machine and this additional material is thrown radially outwardly by the centrifugal force and acquires a continually increasing force radially outwardly.

In accordance with the patent statutes I have described and illustrated the preferred embodiments of my invention, but it will be understood that various changes and modifications can be made therein without departing from the spirit of the invention as defined by the appended claims.
