Driscoll, White Plains, N. Y., and John H. Driscoll, Edgewater, N. J. Qriginal application November 2'7, 1934, .Serial No. 754,988. Divided and this application No vember 29, 1935, Serial No. 52,101, 6 Claims. (01. 226—-125) This invention relates to machines for ?lling jackets or casings with granulated material such, for example. as ground cork, and particularly to machines for ?lling 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 ?lling and packing the jackets or casings of boat fenders, 0 ring buoys, life rafts and the like with granulated ?lling material. One illustrative embodiment of the machine is shown in the accompanying drawing, in which:—— Fig. 1 is a vertical section of a machine em 1 bodying the invention and showing in association with the machine a boat fender casing to be ?lled and packed with ?lling material. Fig, 2 is a sectional view of a portion of the bit or screw which feeds the ?lling 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 25 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 30 shown in association with the illustrative machine in position to be ?lled with ?lling material. As there shown, the fender casing consists of a cy lindrical side wall I and an end wall 2 provided 35 with a grommet 5 through which the ?ller ma terial may be fed into the casing and through which a rope 6 extends. A detailed description of the boat fender andv the manner in which the grommet opening is closed after the casing is 40 ?lled is given in my copending application Serial No. 754,988 ?led November 27, 1934, of which this application is a division. The illustrative machine is provided with a tube 4 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 ?lling machine. The tube I5 is preferably provided on its inner 50 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 55 and through the tube member I5 is a bit or screw I9 for feeding the filler material from the funnel shaped 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'feed-‘ ing of the material through the tube I5. For spreading the ?ller 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 20 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. 25 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 ?lled with ?ller material through a chute 28 30 leading from a supply bin 29. During a ?lling 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 ?lled. As the ?ller 35 material is fed into the fender casing by the bit or screw I9 the casing will gradually be ?lled and tightly packed with the ?ller material. The ?lling operation will gradually force the casing down until the tube I5 emerges from the top thereof. The tightness of the pack will be regu lated by the force with which the fender is sup ported and held during the ?lling operation. It will be noted that in the illustrative machine the packing is done after the ?ller material 45 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 ?ller material is packed downwardly and outwardly by the bit and the expander and insures a tight pack. While the illustrative machine is shown as ?lling a boat fender casing, it will be understood that it may be used to ?ll other types of casings or containers such as bags, drums, barrels, boxes, 2 2,114,103 ring buoys, life rafts and the like, and the ex— pression “casing” as used in the claims is in tended to include all such casings and containers. It will be understood further that the machine may be used to ?ll and pack various types of containers with materials such as cereal prod~ ucts, ?our, feed, bran, gypsum, cement, lamp black, molybdenum, brewers’ grains, clay prod ucts, chemicals, linseed meal, dried milk and the 10 like, and that the expressions “granulated ?ller material” and “?ller material” as used in the speci?cation and claims are intended to include such materials and all other materials which are susceptible of being packed in a receptacle or 15 container. It will be understood that the invention is not to be limited to the speci?c embodiment shown for purposes of illustration as the inventive fea tures may be variously embodied without de parting from the invention. It will also be understood that all of the fea tures of the invention need not be used con jointly as they may be used to advantage in various combinations as de?ned in the sub joined claims. We claim: 1. Means for ?lling and packing a boat fender '30 casing with granulated ?ller material compris ing, in combination, a tube for insertion in the casing and through which the ?ller material may be fed into the casing, a funnel for feeding the ?ller material into the tube, a rotatable screw extending through the tube and beyond the low er 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. 40 2. Means for ?lling and packing a casing with granulated ?ller material comprising, in combi nation, a tube for insertion in the casing and through which the ?ller material may be fed into the casing, a rotatable screw extending through the tube and beyond the lower extrem ity thereof, the spirals of the screw decreasing in diameter upwardly from the lower end of the tube, an expander located in one of the chan nels of the screw below the end of the tube, and means to rotate the screw. 3. Means for ?lling and packing a casing with ?ller material comprising, in combination, a- tube for insertion in the casing through which the ?ller material may be fed into the casing, a 10 rotatable screw extending through the tube and beyond the lower extremity thereof, an expander located in one of the channels of the screw be low the end of the tube, and means to rotate the screw. 15 4.
