Qriginal application November 2'7, 1934, .Serial Divided and this application November 29, 1935, Serial No. 52,101

6 Claims.

This invention relates to machines for filling jackets or casings with granulated material such, for example. as ground cork, and particularly to machines for filling boat fender casings, life buoy 5 casings, life raft casings, and similar casings with granulated material such as cork.

It is an object of the invention to provide an efficient and dependable means for filling and packing the jackets or casings of boat fenders,

ring buoys, life rafts and the like with granulated filling material.

One illustrative embodiment of the machine is shown in the accompanying drawing, in which:

Fig. 1 is a vertical section of a machine embodying the invention and showing in association with the machine a boat fender casing to be filled and packed with filling material.

Fig, 2 is a sectional view of a portion of the bit or screw which feeds the filling material into 21') the fender casing, said view being taken on the line 2--2 of Fig. 1.

Fig. 3 is a sectional view of the feed tube of the machine taken on the line 3-3 of Fig. 1.

The machine of this application is adapted to feed granulated material such as ground cork into casings of various types such, for example, as boat fender casings, ring buoy casings, life raft casings and the like, and to tightly pack the filler material in such casings.

Referring to Fig. l, a boat fender casing is shown in association with the illustrative machine in position to be filled with filling material. As there shown, the fender casing consists of a cylindrical side wall I and an end wall 2 provided with a grommet 5 through which the filler material may be fed into the casing and through which a rope 6 extends. A detailed description of the boat fender and the manner in which the grommet opening is closed after the casing is filled is given in my copending application Serial No. 754,988 filed November 27, 1934, of which this application is a division.

The illustrative machine is provided with a tube member I5 adapted to be inserted into the casing through the grommet 5. Secured to the upper end of the tube I5 is a funnel-shaped member I6. The member 16 and the tube l5 secured thereto are supported by a bracket I'I extending from. a framework I8 of the filling machine.

The tube I5 is preferably provided on its inner surface with longitudinal corrugations I5, as shown in Fig. 3 to reduce swirling of the material in the tube.

Extending down through the funnel member I6 and through the tube member I5 is a bit or screw I9 for feeding the filler material from the funnelshaped member I6 into the fender casing.

The bit or screw I9 preferably extends below the lower end of the tube I5 2. sufficient distance to permit it to spread and pack the material in the fender casing. The diameter of the bit or screw preferably gradually decreases from the bottom to the top to facilitate the feeding of the filler material from the funnel-shaped member I6 through the tube I5 and into the fender casing. The edges of the spirals of the bit or screw which lie within the tube I5 preferably are knife-edged to reduce frictional heat and facilitate the'feeding of the material through the tube I5.

For spreading the filler material outwardly from the bit or screw and for packing it solidly against the walls of the casing, the bit or screw is provided near its extremity with an expander 20, the shape of which is best shown in Fig. 2. This expander forces the filler material toward the outer walls of the casing and produces a tight packing which is impossible by hand operation.

The bit or screw I9 is journaled for rota tion in bearings 2I and 22 supported respectively by brackets 23 and 24 carried by the frame I8. The screw or bit is rotated through a pulley 25 fixed to its upper end through a belt 26 driven by a motor 21.

The funnel-shaped member I6 may be kept filled with filler material through a chute 28 leading from a supply bin 29.

During a filling operation the fender casing may be held by the attendant or supported on a yielding support which will permit the casing to move downwardly as it is filled. As the filler material is fed into the fender casing by the bit or screw I9 the casing will gradually be filled and tightly packed with the filler material. The filling operation will gradually force the casing down until the tube I5 emerges from the top thereof. The tightness of the pack will be regulated by the force with which the fender is supported and held during the filling operation.

It will be noted that in the illustrative machine the packing is done after the filler material emerges from the lower extremity of the tube I5, the bit I9 carrying the expander 20 extending below the lower extremity of the tube I5. With this arrangement the filler material is packed downwardly and outwardly by the bit and the expander and insures a tight pack.

While the illustrative machine is shown as filling a boat fender casing, it will be understood that it may be used to fill other types of casings or containers such as bags, drums, barrels, boxes,

ring buoys, life rafts and the like, and the ex pression casing as used in the claims is intended to include all such casings and containers.

It will be understood further that the machine may be used to fill and pack various types of containers with materials such as cereal products, flour, feed, bran, gypsum, cement, lamp black, molybdenum, brewers grains, clay products, chemicals, linseed meal, dried milk and the like, and that the expressions granulated filler material and filler material as used in the specification and claims are intended to include such materials and all other materials which are susceptible of being packed in a receptacle or container.

It will be understood that the invention is not to be limited to the specific embodiment shown for purposes of illustration as the inventive features may be variously embodied without departing from the invention.

It will also be understood that all of the features of the invention need not be used conjointly as they may be used to advantage in various combinations as defined in the subjoined claims.

We claim:

1. Means for filling and packing a boat fender casing with granulated filler material comprising, in combination, a tube for insertion in the casing and through which the filler material may be fed into the casing, a funnel for feeding the filler material into the tube, a rotatable screw extending through the tube and beyond the lower extremity thereof, the spirals of the screw decreasing in diameter upwardly from the lower end of the tube, an expander located in one of the channels of the screw below the end of the tube, and means to rotate the screw.

2. Means for filling and packing a casing with granulated filler material comprising, in combination, a tube for insertion in the casing and through which the filler material may be fed into the casing, a rotatable screw extending through the tube and beyond the lower extremity thereof, the spirals of the screw decreasing in diameter upwardly from the lower end of the tube, an expander located in one of the channels of the screw below the end of the tube, and means to rotate the screw.

3. Means for filling and packing a casing with filler material comprising, in combination, atube for insertion in the casing through which the filler material may be fed into the casing, a rotatable screw extending through the tube and beyond the lower extremity thereof, an expander located in one of the channels of the screw below the end of the tube, and means to rotate the screw.

4. In apparatus of the character described, in combination, an imperforate tube for insertion into a container to be filled with filler material, means for feeding filler material through said tube, and rotatable expander means associated with said feeding means and lying exteriorly of said tube to pack said filler material toward the side walls of said container.

5. In apparatus of the character described, in combination, a tube for insertion into a container to be filled with material, a rotatable screw extendingthrough said tube and having its lower end lying exteriorly thereof, expander means on said lower screw end only to pack the material toward the side walls of the container, and means to rotate the screw.

6. Means for filling and packing a casing with filler material comprising, in combination, an imperforate tube for insertion in the casing through which the filler material may be fed into the casing, a rotatable screw extending into the tube and having its end projecting exteriorly thereof, an expander located in one of the channels of the screw, and means to rotate the screw.
