To'allwhom it may-'concerm Be aknown vthat I, HENRY Aeon-, a can i 'zenof'the United States, residing at yEmporiun1,.county of Cameron; and Stateof Penny Sylvania?, have invented certain new and useful4 I'm rovements `in Machines for Forming ay Qartri e-Ro e from ExplosiveeGrelatin,"'ofl Whichv t efo'l owing-is a s'peclication.

' w Thisv invention :relates to machines 'for' '10' forming'acartridgerope fronti,explosivev gelal under pressure, thnogh'a nozzle from which the gelatin emerges as ajcontinuous r6 4e, thell` diameter of which maybefrom le'sst an an y inch to upwards of two inches, this rope 'being he manufactureof cartridges -fr'o'm eX- plosive gelatin, which is a plastic substance of'a consistency depending `'upon various conf. ditions,' is generally carriedon by forcing it,

cutinto suitable,l lengths, usuall about eight inches, after emergencejfrom t enozzle, -to thereb form the cartridges Whichare' then suitab y Wrapped so `as to ready-for'- coini mereial use.

Machines of the characterf set forth have usually employed a horizontal 'screw-1 'termed by skilled Workers `in explosivesa paeking screw?, for forcing the explosive gelatinv -through :the nozzle,and associated 'with this acking ls crewrneans' have been employed to eed the plastic gelatin tothe screw.'

Secured detachably by bolts 60 to the upper and lower-parts of a horizontal extension 1b of base 1, which has an aperture 1C, are a'tubular packing screw case 61 and a vnozzle '62, 'the formerbeing preferably of Babbitt metal or suitable alloy, while the' latter is preferably of bronze.

Detachably bolted to the vtop of the pack-l 'lng screw case 61 by bolts 63, is a conical' hopper 22, Whose upper part.23 is in the forrnof a cylindrical ring, which is detach? ably connected to the lower part thereof by the flanges and bolts 24, permitting removal of the upper part for purposes of cleaning.

The co lar 28 so suspends the feeder within the hopper that the feeder does not touch the sides of the hopper, but ma be adjusted toy i fectly flat.

Mounted upon and connected to the frame piece 21 are bearing standards 35 which have vertically and horizontally .adjustable bearings 36, made so by the four screws 36, mounted in which is a horizontal shaft 37. Splined upon the'projecting end of shaft 37 bya feather 40 carried bythe shaft, is a friction-'Wheel39 which may, owing to said splined connection 40, be slidlengthwise of the shaft by a hand-lever 41 pivoted to frame-piece 21 at 42, said lever having a slot and in connection 41c with a shifter 41u slidafile on a stationary guide 41 and having a'fork 41b engaging a groove 41e in the hub of they whee -39. 4The friction-wheel 30 bears against the flat under face of the friction-wheel 34, and as the shaftv 37 is in the same plane as shaft 27, the frictionewheel 34 will be driven faster or slower accordin as the friction-wheel 39 is moved towar or away from shaft 27. The shifting of friction- Wheel 39 may be instantly accomplished by the operator, who thus has the rate of rota tion of the feederunder absolute control so that if the operator finds that the feeder is crowdin the packing screw by feedmg too much ge atin to it, or 1f the consistency of the` A. belt 43 connects pulley 44'on shaft 37 with a .clutch-pulleyV 13 which is controlled by a-hand-lever 13u so lthat the entlre niachnemsy be sto ped or started at will.
