To all 'whom ii may concern:

Be it known that we, ERNST Sononowsli, of Hamburg, Stale of Hamburg, and Go'lrnon) .lssipiciu ot (.ologne, Siate of Prussia, Germany, lm veiuvented a new and useful Improvement in Fxlunels for Charging Containt-rsl for Bursting Charges with Fused Explosives, of which the following isa full, clear, and exact description, reference being had to the accompanying drawings, which forni a part of this specication.

The object of our invention is to produce a funnel which will insure the charging of the container with thevbursting charge, causing the same to chill in the container without the formation of. hollow spaces, also to produce a sutlicient pressure or head upon the material being cast in the container and enabling the taking up of impurities and air bubbles, which would otherwise -be detrimental to the cast of the explosive in the container. Finally, to form a space in the explosive in the container for the insertion of a priming charge in the fused explosive charge.

We will first describe a funnel embodying 4our invention illustrated in the accompanying drawings, and then point out the invention in the claims.

In the drawings: Figure l is a sectional v iew of 4an apparatus involving our invention. Fig. 2 is a section on line 2 2 Fig. l. Fig. 3 is a section on line 3 3 Fig. 1. Fig. 4 is a section on lineA--t Fig. 1.

The funnel, as shown, consists of the main portion a and the neck b. The main portion a and neck Z are jacketed, forming the jacket spaces c and al. The space c has 'a connection e with a source of steam supply, and the space d an outlet f to the air.

gis a hollow piece or former for producing the space in the explosive for the priming charge.

l1, is a' pipe connecting space c with the in- This pipe le terminates at the upper portion of the interiorI of the form g.' i

is a pipe leading from the outletf to the lower portion of interior of former g.

The neck b of the funnel is provided with the ange by means of which it is su ported o n tlie top of the inlet opening of tlli'eA explosive containerv In Vplacingrl tliefunn'el upon the container` afsheet of rub er (n 'roltlierk plastic malenialis placed benefitlithe'flaiige'i ghi and apex @here passing otherwisel thanifito y,

' i l l 4\ A The condensation water aiideliz top of the funnel until`entiarice ntofthe'iio container, and thus provides for a continuous passage of said liquid ex'ilosive. This i causes the filling up of any ollow. spaces tending to form, and thus prevents the vformation of such hollow completely dense and uniform cast ,is ob-` tained. Owing to the heating o f the funnel by means of the steam jacket, any ,choking of the funnel by partly chilled explosive-is prevented. l

The dimensions of the funnelshould preferably be such that the contents actv 1in-a similar manner to the deadhead of`a mold so that the column of liquid ,explosiveL exerts a pressure, during container, upon the portions of the-explo-I sive beneath it, which is being cast. Furthermore, this dead head takesu a'llimpurities and air bubbles which Wouljd otherw;` wise be detrimental to the cast. ing of the funnel may be interrupted at-,will during the chilling of the explosive and the heating is finally eliminated after the chilling has sufieiently progressed. z :ff The funnel may readily be removed may the form g, by temporarily slightly heating the funnel. This somewhat fuses the explosive immediately surrounding the funnel and the funnel can be removed from the cast without diiiiculty. In the space formed by the form g, a shell made of pasteboard,l metal or other materiali containing the primingeharge is inserted and lhe shell is completed.

spaces, 'and thus. a 75 the casting in the The heatY '130 Having now fullydescribed our invenl the former, and a pipe connection between tion, what we claim and desire to protect by Letters Patent is:

1. A funnel for loading fused explosive charges, comprising a funnel proper, a neck for insertion in the container, a fiange for supporting the funnel in the inlet of the container, the funnel and neck portion beingijackcted, said jacket bei ng in connection with a source of steam supply and the air.

2. A funnel for loading fused explosive. charges, comprising u funnel proper. :t net-k for insertion in the container. a tlangc for su )porting the funnel in the inlet'. ot' the container, a seal interposed between the (lange and container inlet.l the tunnel and neck portion being jaoketcd, said jacket being in, connect-ion with a source ot steam supply and the air.

3. A funnel for loading fused explosive char es, comprising a funnel proper, a neck for insertion in the container, a (lange for supporting the funnel in the inlet of the eontalner` in combination with a former snpportcd below the neck of the fnnnot and adapted to enter thc contniner,`the funnel and neck having a jaeketed portion in connection with a4 steam supply and the atmosphere.

4. A. funnel for loading fused explosive charges, comprising a funnel proper. a neck for insertion in the container, a (lange for supporting the funnel in 4the inlet of the container, in combination with .t hollow former supported below the neck of the funnel and adapted tno enter the container. the funneland neck having a jaekcted portion in connection with a steam supply and the, atmosphere, n ipe connection between the steam side of tiie jacket and the interior of the former, and a pipe connection between the interior of the former and the atmosphere.

5. A. funnel for loading fused explosive charges, comprising a. funnel proper, a neel: for insertion in the container, a flange for supporting theI funnel in the inlet of the container, in combination with a hollow former supported below the neck of the funnel and adapted to enter the container, the funnel and neck having a jaeketed portion in connection with a steam supply and the atmosphere, aipe connection 4between the steam side of t e jacket and the interior of the former terminating in the upper portion of 'in the lower portion of the interior of the former and the atmosphere, said last mentioned pipe terminating said former.

6. A tunnel for loading fused explosive charges, comprising :i funnel proper, and a neck for insertion in the. container, said funnel being jaeketed. and having an open ended inlet for heating medium, and :in open ended outlet to the atmosphere.

l7. A funnel tor loading fused explosive inn-ges, comprising a tunnel proper. and a neel: tur insertion in the Container, said fun nel being` jatketed, and haring an inlet for beating medium and an outlet to the :itnnispliere, said inlet and outlet being; dis` connected one front the'otlier. i y A funnel for loading fused explosive charges.. comprising a tunnel proper, and a neck for insertion in the container, said funnel being juckt-ted and having an inlet'4 for heating mediumand an outlet to the atnt'tsplicnc, the dimensions beingV such as to produce a tlend lieadf said inlet and ontletflieing disconnected one from the other.

Si. A funnel for loading' fused explosive charges, comprising a funnel proper, a neel; for insertion in the container. in combinntion with a hollow former supported below the neck of the tunnel and adapted to enter the container. the. tunnel :1ndY neel: 'nox-ing a jaeketed portion in connection with a steam supply and the atmosphere, a pipe countrtion between the steam side ot the. jacket and the interior of the former terminating in the upper portion of the. former. und a pipe connection between the interior of tbe for .mer and the atmosphere. said lust mentioned pipe terminatingr in 'the lower portion ot' said former.
