SPECIFICATION forming part of Letters Patent N o. 679,665, datjedJuly 30, 1901.

l Application filed May 5,1900. Serial No. 15,627. (No model.)

To all whom z't may concern:

Beit known that I, NORBERT CEIPEK, a subject of the Emperor of Austria-Hungary, residing at Vienna, in the Province of Lower Austria, in the Empire of Austria-Hungary, have invented certain new anduseful Improvements in Apparatus for Filling Pulverulous or Doughy Materials into Cartridge-A Like Envelops; and I do hereby declare the following t be a full,Y clear, and exact description of the invention, such as will enable .others skilled in the art to which it apper- -or a substance tains to make and use the'same, reference being. had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention has relation to apparatus for packing pulverulent granular substances suiiciently fluid to be inluenced by centrifugal action into suitable tubes, pockets, or shells, and my said inveution is more particularly designed forloadiug cartridges. A v

My invention has for its object the provision of means whereby the substances referred to are packed into a tube, pocket, or shell by centrifugal force and whereby the degree to which such substances are compacted into the holders can be regulated within certain limits by regulating the speed of rotation ot' the centrifugal drum. This mode of packing substances such as referred to has many advantages in that the packing can be 'elected in a very rapid and economical manner, while in filling cartridges with high explosivessuch as dynamite, explosive gelatin, and the like-the danger of explosion attendant upon the filling of the cartridges in the well-known screw-feed machines and due to the presence of hard foreign bodies is entirely avoided in that there is no pressure or compact suiciently powerful` .to cause such hard substances to explode the explosive. v

That my invention may be fully understood I will describe the same in detail, reference being had to the accompanying drawings, in which#- V Figure 1 is a vertical section of a machine embodying my invention.A Fig. 2 is a fragmentary plan view thereof; Fig. 3, a vertical sectional detail o'f a modified means for sup porting and .guiding the tubes or shellswh-ile -said table having ing and-guiding the tube or shell while being loaded; and Fig. 6 is a right-hand eleva-l tion of Fig. 5. Referring to Fig. 1, findicates the framing of the machine, f' its top or table, having an encompassing vertical flange f2 for the recep-l tion of a hood or cover c, having an eye c', a central aperture f3, into which projects 'a vertical spindle s, having its bearings in a cross-brace f4 of the frame f and being stepped to revolve step S, sa'id spindle s carrying p, driven by a belt b from any suitable motor. The spindle s carries a disk d, to which is secured the centrifugal drum D, open at top andadapted to be closed by a cover C.

In practice the eye c' of' frame-cover chas a belt-pulley vattached thereto a rope run o ver a pulley, and to the opposite end of said rope is secured a counterweight for facilitating the lifting oif and replacing of the cover c.

The drum D has in its peripherytwo rows of nozzles n one above the other, and the internal configuration of .the drum is such as' to readily guide the material to said nozzles, into which screw tubular open-ended tubeor shell holders H, adapted to be closed at their outer end by means of a cap h, one for each pair of su perposed holders.

When the machine is used for loading high explosives that aremore or less fluid or that will become more or less fluid under the inliuence of heat, I provide a heating-coil E, to which any suitable heating mediumas steam, for instance-is supplied to maintain the explosive in a sufficiently liquidcondition to 'be carried into the tubes or shells by centrifugal force.

For general purposes the centrifugal drum -D may be constructed of iron; but when the machine is used for packing substances that lattack iron-as, for instance, nitrate of ainmoniumor acids-I construct the drum of a material that' is indifferent to the-*action of -these chemicals-asI ebonite, for instancewhile parts of the drum which are subjected to greater wear 'are or may be made 'of aluminium oran alloy thereof, and for the sake of lightness the cover c, which, with the tain a suitable blef of the frame f, constitutes'the housing for the drum D, is preferably made of ebonite or aluminium, though .it `may be made of bronze.

The operation ot' the machine as described is' follows: The paper or other tubes ory shells to be loaded are slipped into thel'iolders II with their open ends facing the nozzles fn.,

The caps 7L are applied to close the outer ends of said holders, and thedrum D is charged with 'the material lto be loaded or packed into said tubes or shells. It power is new applied to the vpulley p through belt b to rotate the spindles and drum D, the `material therein will be carried by centrifugal force into the tubes or.Y shells and packed therein, the degree to which suchA material is compacted depending upon the speed of rotation of the drum D, as willbe readily understood. When 'the tubes or shellsaa re loaded, the capsh are l removed and the loaded shells withdrawn, and to facilitate this operation the holdersH have on opposite sides at their outer ends finger recesses or notches h', Fig. 2.

Instead of lockingthe shells I to be loaded 4 into their holders, asj'de'scribed, I may provide means whereby said shells are 'progressively moved along their holders .as said shells are iilled by the material itself, and this arrangement I prefer for loading shellswith.

of a carrier G of substantially thesamelength as the holder H" and having at its outer e'nd a discoidal abutment g of greaterdiameter Athan'thatot said holder.. The carrier G has atitsinner end a friction-braker consisting of a split lug-g2, embracing a preferably cylindrical bar k, and into the earsofsaid lug, be.-v

low the bar, is screwed a clam ping-screw g3, by

i means of which the frictionalcontactbetween .the lug and bar can be regulated to cause the carrier G to move more or less freely along'its bar k, which is pivoted at m to the centrifugal drum D and is normally held in a horizontal position by the leaf-spring 0. On. the

'bark is mounted a splitlug 7c', embracing the v same,the ears of said lug having screw-threaded perforations for a clamping-screw 7a2, so that the lug 7c can be 'secured to said bar lo at I any point of its length, according to the length of the 'carrierv and the length of the tube or shell to be loaded and its holder, said lug 7c' performing the function of'a stop and limiting the outward movement of the car- 'rier andthe tube or shell. The operationof these devices is as follows,it being assumed `that the machine is boing prepared forloading paper tubes orfshells with a lg'elati'nous high explosive, the housing beingsuitably heated: rIhe lugsk are removed from their bars 7c, and the latter are turned down against the stress lol their springs o, the holders H' are secured to their respective. nozzles n of the drum D, andthe tubes or shells e' to be loaded are slipped onto their respective holders I-I'., The carriers G are now slipped onto their re' spective bars and the friction between the latter and the lugs g2 regulatedv by means of the clamping-screws g3. The lugs k are now adjusted on bars 7c, according vto the length 'of the travel ofv the carriersG, after which said barsare turned'up into ahorizontal position and held there by their springs. 0, so `that the abutment-disk gf of the carriers -G willv bear against the. closed endofthe tube -or l shell e and its holder. A charge of high-ex-f plosive is now introduced into drum D, and after replacing'the covers C and csaid drum is rotated at the desired or required speed. As the material is carried intovthe holders H and compacted' therein at their outer ehdsl the. pressure' exerted on the like ends of the shells e and therethrough on theabutment- 4disks g on carriers G, the latter, together with the shells being loaded, are moved along the bars k until further outward motion of said carriers isstopped'by the lug g2 thereon com-ing inv contact With the, fixed lug k' on bar k, which also serves as a support for the outer free end of the carrier. `Inasmuch as the extent of travel of the carrier G depends upon the length of' the shell 'e to be loa-ded,

the latter will be loaded 'when Ifurther outward movement of the carrier= is stopped.

The lug 7c i's now removed from its bar 7c, the carrier G slipped off, or the bar with its carrierfmay simply be turned down on itspivots' fm, when the loaded tube or shell e can' be readily removed from its holder H. The ad- IOO justment of the parts isof course such vthat' when the travel of thecarrier is stopped there will remain 'a sufficient portion ofthe inner end of the tube or shell c unfilled, so that it may be'properly closed. I

In Figs. 5 andf6 I have shown a slightmodicationof the appliances just described and illustrated in Figs. 3 and 4, the carrier G be.- ing here dispensed with and the bar K constructed to forma cradle #03. On thebar K is mounted a split bearing B for a rod/r, having a discoidal abutment b at its inner vend performing the same function as theabut'- ment g' describedin referenceeto'vlifgs.grand 4. The friction between the bearing and rod 'r isregulated Iby a clamping-screw fr?, While said bearing is adjustable on bar K by means of a binding-screw b2., It is obvious'that here also the pressure of the material on Vthe bottom or outer end of the tube cr shell e and therethrough. on the abutment b willk cause saidrod and tube or shell e to move outwardly untilthe said abutment comes incontact with the split bearin g B, the construction being materially simplified and the manipulation facilitated, as will be readily understood.

Of course it will be understood that the socalled holders H or H are mere prolongations of the nozzlesn or n', though in practice I construct the said prolongations for connection with the nozzles, so that the length of the part of the nozzle projecting from the periphery of thedrum may be Varied to suit the length of the 'tube or shell to be filled., Prolongations H or H of dierent lengths can thus be-interchangeably used on the machine. It Will also be understood that by regulating the frictional contact between the fixed and slidingparts 7c and G or K and r, so that said sliding parts Will oder more or 'less resistance to the pressure of the material forced into the tube or shell e, said material will be more vor less firmly packed, and this, as hereinbefore stated, may be further regulated by regulating the speed of rotation of the drum D.
