Application filed July 28, 1910. Serial No. 574,406.

I To all whom it may concernr A v Be it known that I, HENRY AI'JCHU, a citizen of the United States, residing at Emporium, county of Cameron, and State of Pennsylvania, have invented certain new anduseful Improvements in- Machines for Making Paper Cartridges or Shells, of

Which" the following isa specification.

chinery' for the formation of shells of the character set forth and has forits object the provision of a novel automatic machine which ,will be adapted'to receive from any approved type of spiral wind continuous tube-forming machine, a tubular contin'u 'o'us papertube which is tobe' transformed into a, cartridgefor shell, tonutomatically sever the tube at a predetermined-time. op-' crate o'n' said-severed tube to crimp or form amend-thereof and to automatically eject -the-finished shell ready fo'rfilling thereof by hand. or machinery with the explosive "so'fthat the dynamite cartridge' may be subsequently closed at the'open end thereof.

. In; my invention, the continuous tube of Qp'aper whichis formed by any approved machine, is presentedto one of a series of vro-, 't atabIymounted 'mandrels of my machine and at a. timepred'etermined by its feed, automatically operates mechanism releasing I a saw which sevens the continuous tube,

thereby.- cutting -ofi the shell therefrom;

: thereafter the mandrel -wh.ich has received the shell is 'automati'callyturned into posit'ion .where"novel folding or crimping Iinechanism closes the. outer open end of said normal, position. ready; fora repetition of the 0 'erat1 on-. on; another; sectionv of the conf tmuous paper tube which has been j-recei'ved '1 '--on a succeeding mandrel ,.andftheffinished.

shell" is finally .automja-tica'lly {discharged fromits mandrel, preferably-bathe use of air pressure which is introduced ngafinst the'z .folded-a'zhd-therofat a predetermined' timef shell: and, preferably, mechanism is also used whichstamps the shell With its desigv na'ting charactersfor tradeemark, the cuttingsawmeanwhile having been restored to its- In the accompanying drawings:-Figure 1 is a front elevation of the machine; Fig. 2,'a side elevation; Fig. 3, a longitudinal partial section of the folding and crimping plungers; Fig. 4, an end view thereof; Fig. 5, a sectional detail showing the interior construction of the anandrels, whereby the shell is discharged; and Fig. 6, a detail of the cam arrangement'for operating the f folding. and crimping mechanism.

The machine frame 1 supports a fixed shaft 2 on which is rotatably mounted, be tween set collars 3 and 4, the hub 5 of the mandrel wheel which is composed of said hub and aplurality, four in the present instance, of hollow mandrels 6, Whose inner ends rest against the shaft 2, being packed in any desiredfashion, in position to 'com-' niunicatc, at a certain point of their revolution on shaft 2. with an opening 7 5) which communicates with the hollow inter r1or' 8 of said shaft 2, and rece ves air pressure which is admitted to the lnterior of the shaft 2 via the pipe 9 (Fig. 2); In consequence, when. a-give'n mandrel has its interior in linewith the ports 7, the air pres sure enters the mandrel and presses against theshell containedthereon and effects its discharge, a. plurality ofopenings 10 being provided in the end of each mandrel to distribute the air against the closed or crimped end of the shell. Each of the mandrels is provided with an adjustable. nut or collar 11, whose adjustment can be effected by providing screW th'reads 12 on the mandrel, or, collar or nutcan'be provided With a set screwand the screw-threads be dispensed with; Slidable on the'mandrel is a gage collar 13 which may be provided with a spline to slip in a. slot 14 inthe mandrel (Fig. 2). The gage 13 forms a .movable abutment for the free end of the continuous paper tube'1'5 which isof slightly greater interior diameter than the diameter of the mandrel and is formed by any suitable spiral Wind machine, such as A, which forms no part of-my invention except in its association with. my machine, whereby the continuously formed tube" ofthe lmachine -A is advanced and. telescopes over the -mandrel .6 until itstrikeslagains't the gage 13, and, by its ad- .vance; moves "the gage until it contacts with 'the "set'c'oll'ar 11, Whose adjustmentregulates no the length of the shell which'fwill becutiofi. The hub '5 is provided :with an integral 'helt'pulley' 16 which is co nnectedbly an at]- i V ratchet wheel 18. By'employing the ad-.

justable. connection 17, the ratchet wheel 18 justable slot and bolt fastening 17 to a can be set'and-clamped so that the functions of the'machine will 'be pro perly timed. The ratchet wheel has teeth 19 corresponding in number to the number of mandrels employed. ""Various mechanisms of the ma- 1;. Pivot'ed'to a part of the frame-work 1 1S chi are driven by a shaft 20', said shaft being belted at 21 to the pulley 16.

' {deg 22 having atoe 23 adapted to engage vided with atail 24.. Slidable in bearings =1 V 1 mallyactuated by "a' sprlng 26 to hold its the-teeth 19 of the ratchet wheel 18 and proonthe frame is a trip bar which is norfree ka'nd'27in position 'to'iengage' a lug'28 on a drop saw frame 29,'which is loosely- ,journaled on a shaft 30 and carries a mutilated friction wheel 315-the frictionwheel being secured to the frame 29 by an adjusts able slot and belt connection 32 whereby it can be adjusted in relation to the'saw frame 29 to regulate the operation thereof. The 25' saw'fraine carries'a rotary. saw 33- which is belted to a pulley 34 secured to the shaft 30, whereby the saw is continuously driven .at a'high rate of speed;

The numeral'35 designates a friction pinion on is shaft 36 which is continuously driven by a belt. 87 fr'om'shaft 20, said pinion} being ositioned with its friction face -just out o I engagement with the wheel 31 when the saw frame is caughtand. held by;

rod 25 after beingraised. will be under stood that a gang ofsaws adapted to oper-' ate in 'af step-by-step manner could be usedinstead of a single saw.

When-the'paper tube 15-pushes the gage- 13 from the normalposition shown in dotted lines until it strikes the depending arm 38- connected to the ,bar25, the. bar 25 is ushed'back from its normal-position; therey releasing the engagement thereof. With .the lug 28, whereupon thesaw frame-29 ydropsby gravity, the saw 33 quickly sever-' ing the paper tube 15. and thus cutting ofi' a section to'be subsequently used as a shell.

After severing the tube the frictional fafties of-greaterradius'of the pulley 31 engages with the pulley whereupon thefsaw' frame is'rapi-dly elei atedto normalflrai'sed position and just before it res'nmesrits en .gagement; with the end 27, it bearsagainst the tail 24 of the 'dog'22 and releasesjthetoe f 23 of said dog frorfithe tooth 19 with which" saidfoe was. previously engaged. Thefpulleys 31 and 35 disengage just before the'lu'g' 28' and rod 25 become engaged.

, The belt 21 is sufficiently 10s e' 6; area will continuously rotate around the pulley 1-6'while tha' ratc'hetwheel'18-- and the man.- drl wheel are lockedf but immediatelyupon I the release, of the toe from" the tooth 19," the frictional; engagement of the belt 21 ger '54 is end 60 "with pulley 16 becomes sufficient to cause rotation, of the ratchet wheel 18 and the set of .mandrels-so that the mandrel carrying the severed shell is turned in the direction of the arrow 'from a horizontal to a vertical position ready for the crimping or folding of the end of the shell.

' Loosely rotatableen'the shaft 2 and lo.- cated between set collarsv 39 and 40 (Fig. 2) is a belt pulley 41, a ratchet wheel 42 having a'single tooth 43, and two earns 44 and 45 (Fig. '6) which are connected by slot and-bolt connections '46 with the. ratchetwheel 'so'that they can be adjnsted in relation to each 'othrgandhence the crimping,

' folding and stamping mechanisms operated thereby'rnay bertimed'to. suitably act. 1 To rotate the'pulley, ratchet wheelfand cams, all of which are securelyc'la-mped together, there is provided a belt 47 which runs over" a pulley 48 on the shaft 20.

: Journaled in" suitable bearings'fon the main frame is a rock shaft 49 having arms 50 and .51, the former being adapted to engage with'the tooth 43 to normallylock the ratchet wheel 42 'and the cams 44 and'45 against rotation. The ratchet wheel 18' car- 'rles. trip pins 52-, suitably positi oned which are adapted. to engage the arm 51 immediately after the release of the ratchet wheel 'l 8'by .thedog 22.

'The belt 47 is adapted tor-slip while the ratchetwvheel 42 is locked by'the .arm 50,

but immediately upon the rocking of the shaft 49 by the engagement of one of the.

pins 52 with the arm 51, and consequent release of the ratchet wheel 42, the tension of the belt'47 is such that motionjwill be immediately' transmitted to the pulley 41 and the cams 44 and 45 will turn -a complete revolution, being again stopped by the engagement-ofthe arm '50 with the tooth 43, such complete revolution of the cams 44 and 45occurring during a quarter revolution of the ratchet wheel18 and {the arrangement being such that the cam 45 will have: a slight lead over the cam 44 for the, purpose of. 4

To efi'ect these operations, Iprovide apivoted rocker Gtiwhich is engaged at 67 with the plunger 54 and has a spring-actuated rod 68 provided with a roller 69 -which is adapted to engage the lever 7 4 provided with aeombined stamp and clamp 75' and retracted by a-spring 76,,the

stamp 75 bearing suitable wording which 'isintended to-be'printed on the shell and,

while effecting the printing operation, serv ing as a clamp to, prevent the shell from twisting on the 1mandrel and also to lock the mandrel wheel against backward turns ing. -The operations are timed so that the cam "raisesthe roller 69 out of the dwell 1 of said cam, causes" the crimping plunger 54.

to. be lowered onto the free end of the shell which is prestmted thereto and immediately thereafter, the levels74 is operated and/the.

stamp and clamp 75 performs itsfunction. Very shortly after the crimping o eration, thus. described, has heeneflected, t 1e roller 72 is lifted out of the dwell of cam 44 and the plunger 58 is depressed inside of the of the mandrel.

plunger 54 and takes hold of the erimped end of the shell and folds it against the end In order that nice adj ustment may be had, I provide rods 68 and 71 with turn buckles 77 and 78.

, The sequence of operations is as follows: The contlnuonsly forming tube, 15 is fed onto the mandrel 6, engages the gage 13 and presses itnntil the gage strikes the arm-38, whereupon the saw frame 29 is released and the rapidly'rotating saw drops 'onto the paper tube and'seversit. Thereupon the friction wheel 31 engages the friction pin-- ion- and the saw is returned to normal [)(ISlllnll aml re-locked by the engagement of the parts 27 and 28 ready for a subsequent operation, but in returning to normal posi- -'tion, the lug 28 engages the tail 24 of the do" 22 and throws the toe 2 'l'out of en a e i P) h h ment with the tooth 19 of ratchet wheel 18, '.wliereli[u:i1-tl1e' belt 21 rotates the mandrel wheel to bring the shelltto verticalposition ready forrrilnping and folding, but. in rotating, the pin 52 strikesthe arm 51 and causes release of the ratchet wheel 42. whereupon the hclt l7 rotates the ratchet wheel 42am] the cams 44 and .45. \Vhen the mandrel wheel has turned the quarter revolution set forth, the toe 23 engages a succeeding .maridrel .when in that positiom the shellis combination adapted to receive a continuous tube when tooth 19 so .thatthe mandrel wheel does not turn farther, but the crimping, stamping and folding operations are then erfected. In the meanwhile another lengt of the tube 15 havin 'struckthe gage '13 of the mandrel Whic was previously lowermost, that gage is pushed'inwardly'and the saw again released and the foregoing operations are repeated, but the rotatlon of the cams 44 and 45 has in the meanwhile brought'the dwells thereof-in position so that the roll- ,ers 69 and 72 drop into said dwells and the crimping and folding operations having been completed, the plnngers 54 and 5.8 are raised from the erimped and-folded end of the shell so that the next uarterrevolution I of the mandrel wheel will ring the finished shell to a position diametricallyo posite to that in which it wasl'ocated when 'eingse.v

ered from the tube15 The next-quarter revolution of the mandgel wheelbrings-th'e shell into its lowermost position, whereuponthe gage 13 falls by gravity and the compressed air having beenadmitted to the blown oft.
