SHEET 2 BF 2 /N VE N 7 0R 055 Mama/0x25 WM A T TORNEY5 DISPENSING APPARATUS This invention relates to dispensing apparatus of the kind including a container for articles to be dispensed, the container being adapted to be associated with a fluid for relative movement therebetween, and ejecting means for ejecting a mass of said articles from the container into the relatively moving fluid so that the articles are scattered within the fluid. The invention is concerned particularly with dispensing apparatus for automatically dispensing articles such as needles from projectiles in flight.

If dispensing apparatus for dispensing a pack of needles from a V projectile includes a system of levers, springs, etc., which system is operable, when it is required to dispense the needles, to move the pack of needles laterally of the projectile into the select stream thereof so the air-flow over the pack scatters the needles, it will be appreciated that the system will occupy space within the projectile which might otherwise be filled with needles and that a significant proportion of the power developed by the power plant of the projectile will be employed in carrying the system rather than in carrying the needles to be dispensed.

According to this invention there is provided dispensing apparatus including a container for articles to be dispensed, the container being adapted to be associated with a fluid for relative movement therebetween, and ejecting means for ejecting a mass of said articles from the container into the relative moving fluid so that the ejected articles are scattered with the fluid, wherein the ejecting means includes an elongate member of flexible material, the elongate member being adapted to be wrapped around part of the periphery of a mass of said articles within the container and to be connected to actuating means which act to straighten out the elongate member, the arrangement being such that, when the elongate member is wrapped around part of the periphery of a mass of said articles contained within the container and is straightened out by the action of the actuating means, at least part of the mass of said articles contained within the container is ejected from the container by the straightening out action of the elongate member.

Preferably the container comprises a cylindrical tube.

Conveniently the elongate member passes through the axial passage defined by the cylindrical tube, one end of the elongate member being on one side of the cylindrical tube and the other end of the elongate member being on the other side of the cylindrical tube.

The container may be one of a plurality of containers each of which comprises a cylindrical tube, and the elongate member may be arranged to pass through the axial passage defined by each tube so that one end of the elongate member is on one side of the plurality of containers and the other end is on the other side of the plurality of containers. The dispensing apparatus may include a plurality of discs of substantially the same diameter as the inside diameter of the tubes, each disc being arranged to be located between a respective side by side pair of the tubes in a plane normal to the tubes. Optionally the discs may be secured to the elongate member which conveniently comprises a fabric or aluminum tape.

According to a feature of this invention an article dispensing pack comprises a said dispensing apparatus, the or each container containing articles to be dispensed through an opening of the respective container. The elongate member may be wrapped around part of the periphery of a mass of said articles contained in the container, or in one of the containers so as to define at least one open loop, the closed end of the or each loop being remote from the opening through which the articles of said mass are to be dispensed. Where the or each container is a cylindrical tube, the elongate member may be wrapped around part of the periphery of a mass of said articles contained in the cylindrical tube, or in one of the cylindrical tubes in such a way that it extends through the axial passage defined by the cylindrical tube when the elongate member has been straightened out and the articles have been ejected therefrom. Conveniently the elongate member is wrapped around part of the periphery of the mass of said articles within a said cylindrical tube so that it follows a path which extends initially between the articles and the tube in a generally axial direction from one end of the tube to the other, which path then turns and extends part way across said other end of the tube in a generally radial direction across the articles to a point upon which it extends back through the articles in a generally axial direction to said one end where it turns and extends in the same generally radial direction across the articles and which finally extends between the articles and the tube in a generally axial direction from said one end to said other end. Where there are a plurality of said cylindrical tubes, the path followed by the elongate member through one of the tubes of each side by side pair of said tubes may be of the opposite hand to the path followed by the elongate member through the other tube of that side by side pair of tubes.

Preferably the articles comprise needles of aluminum foil. Conveniently the aluminum foil needles are aligned axially of the tube within which they are contained and are arranged in bunches which are surrounded by paper bands. The or each cylindrical tube or disc may be made of cardboard.

According to another feature of this invention a projectile has separable forward and aft portions which cooperate to house a siad article dispensing pack, one end of the elongate member being secured to the forward portion and the other end of the elongate member being secured to the aft portion, the arrangement being such that, upon separation of the forward and aft portions whilst the projectile is in flight, the article dispensing pack is exposed and the elongate member is straightened out so that articles contained in the article dispensing pack are ejected from the projectile.

One embodiment of this invention will now be described by way of example only with reference to the accompanying drawings of which:

FIG. 1 is a diagrammatic sectional view of a projectile carrying an aluminum foil needle dispensing pack in accordance with this invention;

FIG. 2 is a perspective view of dispensing apparatus in accordance with this invention comprising three containers filled with bunches of aluminum foil needles; and

FIG. 3 illustrates diagrammatically the projectile of FIG. 1 with its forward and aft portions separated and the aluminum foil needles ejected.

l060ll 0246 Referring to FIG. 1 a projectile has a forward portion 11 and an aft portion 12. The detailed construction and operation of the projectile 10 forms no part of the present invention. It is sufficient to understand that the forward portion 11 is adapted to be secured to the aft portion 12, as illustrated diagrammatically in FIG. 1, so as to surround an article dispensing pack 13 which fills the load carrying space 14 of the projectile 10, and also that the projectile 10 is provided with means whereby the forward portion 11 can be separated from the aft portion 12 during flight.

The article dispensing pack 13 comprises three cardboard

cylindrical tubes

15, 16 and 17 which are mounted coaxially within the load carrying space 14. The axial length of each

tube

15, 16, 17 is approximately one-third the inside diameter thereof. Each

tube

15, 16, 17 is filled with aluminum foil needles 18 which are aligned axially of the

tube

15, 16, 17. The needles 18 are arranged conveniently in bunches which are surrounded laterally by paper bands 13. Each needle 18 extends substantially the whole axial length of the

respective tube

15, 16, 17 and is very small in its lateral dimensions.

A fabric tape 20 is passed through each

tube

15, 16, 17 so as to follow a path from one side to the other of the whole pack 13. One end of the tape 20 is fixed to the forward portion 11 of the projectile 10 and the other end of the tape 20 is fixed to the aft portion 12 of the projectile 10.

Recesses

21 and 22 are formed respectively in the forward portion 11 and the aft portion 12. A length of the tape 20 is stored in each

recess

21, 22, the stored length in each

recess

21, 22 being longer than the axial length of the overlapping parts of the forward and

aft portions

11 and 12.

The path through each

tube

15, 16, 17 is such that the tape 20 is threaded first between the needles 18 and the tube wall in a generally axial direction from one end of the

tube

15, 16, 17 to the other, the tape portion emerging at said other end is turned through 90 and passed radially to the center of the

tube

15, 16, 17 across the ends of the needles 1% contained therein, is then threaded back between the needles 18 along the axis of the

tube

15, 16, 17 to emerge at said first end where it is turned again through 90 and led in the same radial sense to the point on the

tube

15, 16, 17 diametrically opposite the first tape portion threaded between the needles 18 and the tube wall, from which point the tape 20 is threaded finally between the needles 18 and the tube wall to emerge from the other end of the

tube

15, 16, 17 and be passed to the

next tube

15, 16, 17 to follow a path through the

next tube

15, 16, 17 which, as can be seen from FIGS. 1 and 2, is similar but of the opposite hand. It will be understood that the path of the tape 20 through each

tube

15, 16, 17 defines two open loops within that tube; the two radial legs of that path define the closed ends of the loops, the three axially aligned legs of that path define the sides of the loops, and the central axially aligned leg is common to both loops.

Two

cardboard discs

23 and 24 of substantially the same diameter as the inside diameter of each

tube

15, 16, 17 are located so that the disc 23 lies between the side by side pair of tubes and 16 and the disc 24$ lies between the other side by side pair of

tubes

16 and 17. Each disc 23, 241 is in a plane normal to the axis of the

tubes

15, 16, 17.

When it is desired to dispense the needles 18 from the projectile 10, the forward portion 1 1 of the projectile 10 is separated from the aft portion 12 so that a pull is exerted on the tape 20 by the separating

portions

11 and 12 to straighten out the tape 21). In straightening out, the tape 20 throws the bunch of needles 18 out of the

tube

15, 16, 17 and out of the projectile 10, the pack 13 having beenuncovered by the separation of the forward part 11 from the aft part 12 as shown in FIG. 3. When the'bunch of needles 18 are ejected from the projectile 10, they disintegrate and the needles 1% scatter. The length of the tape 20 stored in the

recesses

21 and 22 ensures that the pack 13 is uncovered by the separation of the

projectile portions

11 and 12 before the tape 20 is straightened out fully.

Various modifications and refinements of the embodiment described above may be employed without departing from the scope of this invention. For example, the cardboard discs 23 and 34 may 'be secured to the tape so as to act as a means of dislodging needles 18 which remain in the

cardboard tubes

15, 16, 17 during the tape straightening out process. Alternatively any other suitable means of dislodging needles which remain in the cardboard tubes during the tape straightening out process may be employed. The tape need not be fabric, any other suitable material may be employed for example an aluminum tape. It will be appreciated that any other suitably flexible elongated member which is strong enough to carry out the'necessary ejection action whilst straightening out may be employed as a tape. It will be appreciated also that various other articles may be ejected from a dispensing apparatus in accordance with this invention, for example leaflets, copper needles or needles of any other material.
