. Application illed September 28, 1911.y Ieril No. 851,338.

To all whom it may confient.-

.lle it known that I, HmAM I. HALL, c

citizen of the United States, residing utv New York city couiit of Newy York, and Stute of New orlr, ave invented e newr und useful Improvement in Cartrid e-Londing-Machines, of which 4the following is u fu l,

cleur, und exact description, reference bein -lmd' to the accompany' drawings, whi formu part of this speci cation. p

The object o1 my invention in enerel, is to provide u power machine or ling und packing paper shells with dynamite or other explosive. Such e machine is net forth in the atent issued to me March 22, 1898, No. 60 38.

Illie more particular object of my invention is to improve the construction und op eration of the machine of seid patent and of later machines of the suine general char ucter.

I willrst describe the construction and operation of in improved machine and will y point out the more notable of the advantageous dentures thereof.-

In the drawings: Figure .1 is u sectional elevation of `the machine. Fi 2 is a lan actuating mechanism for the view of the u per portion o the mac e. Fig. 3 is 'an e ovation of theportion'cf the machine shown in Fig. 2. Fig. l and Fig. 5 are detail sectional views of the lower portion of the machine.

The ceilin 101 divides the machine into two parts. r ne art, comprising the shellholder, hopper, eedc1iute, and u. part of the temp-guiding mechanism, is located on the lower floor. The upper door contains the actuating mechanism for the vertically reciprocating temps, the lutter extendin from one door to the other, as in my sui patent. l

My improvement relates mainly to the temp rods; und certain parte of. the machine, such as the means for :feeding the dynamite to the hopper the means for opening und closing the shell holders, and the means for crimping and folding the shells, are not shown, us they form no part of my present invention.

Referring lirst to 1: 10 is a revolnble shell-holder similar in operation tothe one set forth in m sind patent, The holder. carries Qt e' shelle1`1 to be loaded. Above the shell holder is the hopper 12- movable we e 2 is teken u shell- I ade ted to contain the dynamite to be pac ed into the shells. Above the hopper 12 is the feed-chiite 18.

14, 14, etc., represent the plungers or temp rods, which reciprocate vertically within the hop er 12 und pack the dynamite in the sliel s 11. The temp rode 14 ere guided neer their upper ends in the guides 1 Secured to euch temp rod 14 is c collar 16, connectcd by means ofs connecting rod 1T, with the end 'of a. steeltube 18 rigidly festened on the end of an arm 19 rojectin from an eccentric strap 20. Enc rdd 11E 'and its corresponding collar 16, rod 17, tube 1B, arm 19 and stru 20, constitute en independent tamping evice. Each eccentric strap 20 surrounds scmi-circular wedges 21 and 22, the former being pinned fast to the strap und the latter not being connected to the stru except frictionully iis hereinafter describe Euch air of wedges 21 und 22 surround, or to e more accurate, neurly surround, the drum or c linder 23, which is slightly longer than `e width of the space occupied all theutam rods, straps und wedges. T e' c linder 2 is mounted on und secured to t e shaft 24, which extends completely across the machine and turns inbenrings en the machine frame 100.

Esch movable wedge 22 is normally held tightly in place between the corresponding strap 20 end the cylinder 23 by means of a block 25 secured to wedge 22 and pressed in the 4direction of the sing; arrow lily; means of u spring 26 confined tween blo 25 und a. lug 27 on the strep 20. By means of adjusting screws 28 the tension of the sprins 26 muy be regulated. vBy means of t e a justuhle lates 29, the wear on the The shaftis continuous oscillated by the following means. 30 is t e main driving shaft turning in bearings on the me chine frame. At each side of the machine the shut 30 is provided with' u spurr 31, which meshes with e ur shaft 83. On the lutter aft is a. crunk 34, which, by means of e crankin 35 und a connecting rod 36, is connecte with u crank pin 37 on the crank 88 secured to the shaft 24.

40 is c double-actin cylinder havingl e.-

coipressed cir inlet un outlet et 41 und 42. rni'iie o the zucchine ct opposite sides there,

gear 3 on u 43 are stationery arms secured to the z of and having bcariii s for the shaft 44, which extends comple ely across the machine. '10 the shaft 44 is llyed, at one side of the machine the bell-cra lever 45. One arm of the heli-crank 45 is connected to the piston rod 46 of the cylinder 40. The other arm of the bell-crank 45 supports the shaft 'opposite sidesof t e machine. On. each le 'ver 50 is a lug 51 to engage a lug 52 on the corres onding eccentric strap 20..'

' each lever 5 is a' lu 5 3 ada ed to engage liliA a dog ing lever 54 ci-ums. on the stra' 20 an fitting into a recess 554 in the movab e wedge 22.

' To make the machine extremel sensitive lead weights 59 are laced on eac eccentric strap 20 op osito t e steel tube 18. They can be in e to 'nearly balance the temp rods14.

In the drawings, Fig. 1, the machine is shown as at rest and with all the temps dogged. Then cylinder 23 'is oscillatin as described. The weight of the temp-'ro s 14 'causes the upper ends of the levers 54 to bear against the vertical sides of the lugs 53 thereby causing the wedges 22 to be moved in the direction of the double arrow and out of driving enga entwith'the cylinder'23 and strap 20. he cyinder 23 is therefore ineffective to vibrate e strap 20.'

In starting the machine air's `admitted 'into the cylinder 40 throughA port'41. This 'imparts motion to the cam levers 50. Tlie lugs 51 on levers 50 engage the lu s52 on the eccentric straps 20 an cause t elatter to turn, thereby depressii the various tamp rods 14 until hey pass rough the? hopper and uncli the first articles of., owder into the s ells. It shoul be noted t at this 4f ir'st dowistroke of the tamping rods isja' positive oiie1 thereby insuring 4levers 54 during t chine. As soon as the air is released from the cylinder 40 the ends of t e shells shall be packed with a ccr tain degree of tightness and thi'isavoiding softness inthe lower ends of the shells.

he cam-levers 50'ride op the til-lodd, the

u 53ared1sen'- a' rom e' o' gs Eegiigst stroke of thgildiig# ogios'in air ateneo returns the cam evers to t en` initialpositions. As soon as the linder thhas Acom-- leted the first stroke e oscillatm cyliner 23 reverses its motionI :from the irection' of the double arrows to-the direction of the single arrow. At once the movable wed 22 )am and cause the stra s 20 to turn with the cylinder 23, thus h of powder packeld that "the lower As lar taii'ipng ng the taiuping' rode 14 e definite distance lto thel upper ends of their strokes. As soon as the cylinder 23 again reverses its motion and turns in the direction of the 'double arrows, the straps 20v also reverse their motions and adcwnward movement is imparted to the tamping rods 14. As soon as the tamping rods. 14 ass through'the hopper and c'oriipi'ess en c cli tional amount of owder into the shells with al predetermined e 'ree of tl htness, the resistance to further` ownwar movement of the tampingrods arrests them and also their respective' stragis 20, which slip relatively to the cylinder 2 The Vtension' of the. s rings is 'sli htly reater than the weight o the temps, t ierey preventin the weight oi the temps from oV ening up t ewedge,said springsV serving t erefore, to hold the'cylinder'23 and straps 20 in driving engagement during the down 'stroke of the temps until their tension is overcome by the o p osing resistance of the paclredgpowder. he amountV of compression 'that is given -to the powder in the shells is thus determined by the difference between the weight of'the temps and-the tension of their respective -springs 26. fllie amount of compression can be varied by varying the tensin of the springs -26.`by means of the adjusting screws 28. The-composite drum continues to oscillate and the eccentric p straps 20 forming part thereof continue to 'slip to' an extent roportionate tothe amount into the respective shells at eech'doWn-stroke of the temp-rods. lAs soon as any shell is completely-filled, the *corresponding dogging lover 5 which has y a ed the corresponding lug 53 and thus iii the corresponding' lever 50, slips beck ,ofsaid lug 53, and theV lever 50 dropping, thisparticular dogging lever 54 is dogge At once the point of lugli contactingA with the lever 54 ecomes the iilcrum of t Vatie-- ver, and the power. the wei ht of the corresponding temp rfid 4) acts iiipve the corresponding wedge 22 out oi driving engagement with the cy1inder23.- Immediately the correspon ing "strap 20, aiidlikewise the corresponding tampiiig rod 14, are brought .to rest. Thereafter in the oscillation ofcylinder 23, no work is done upon this particurod. As soon as all the temps are dogged in a similar manner, the machine is again brought to rest, andthe-shell c lin- Vder..10 is turned to bring a new set of s ells into positionto be filled.; j;

Instead of providing stirrers m the hopper, the tampug rods themselves are; 'ven a 'bratorymovement coincident wit theii rijp and down moveiiieii't thereby avoiding t re possible danger thaterises' from thc em ployment of. independent. mechanism :loi stirring. The actuating mechanism for imparting this vibratory Vmotion to the stirreri .will now be described.

The driving short has keyed to it, on ench sido of the machine, a emr gear (l0, which drives a spur goor (il, coso on the shaft Bil. (ln the hub of ,door (ll. is n projecting arm (l2 which engages alternately the inwardly project lng parte mi und 64 of n cum G5. This ram euorclcs tho arm U2 and is carried on one arm of a liclldirnnlrlever (i6 pivoted on a pin 6T turning iu bearings on thc machine frame.' The other arm of the bell-crank 66 carries a slotted bar (i8, which extends entirolv across the machine. This slotted bar is .wir c 4enough to allow the tam ing rods 1-1 to slide easily therethrough.

T ie alternate engagement ot' com progections 63 and 64 by the rointnarni (i2 vibrates the bell-crank Bti and t e'refore vibrates'the tamping rods 14. The ratio of the gearing is such that the damping rods are' given a complete reciprocntlon down and up when they are moved to one side of the hopper and another complete reciprocm tion -w ien they are moved to the other side of the hopper.

Each temp-rod: 14 is equip ed with a guide iece the opposite en s of4 whic curry' ber or other suitable material. On

ther'downward stroke of the temp rod, the guide piece 70 contacts with one of the metallic guides 71 fastened to the frames 72 ext-ending beneath the ceiling 101. These guides correspond in shapc with the sha e of the hopper, the ob'ect sing to car the rubber-tipped end o lthe temp-rod own nlon the side of the hopper but not quite tou ming it.

B means of above devices, the lower ends of t o tomp rods are caused to move down through the powder obliquely and close to ihcslanting walls of the hopper, first on one side and then on the other, tiereb preventing the formation of any open poc ets in the powder and preventing the accumulation of.

powder along the side walls of the hopper.

To prevent. the tnmps from moving' from the position to which vthe are brought at each movement of thebe -crank levers 66, lead weights- 69 are placed directly over the fnlcrum of said 'bell-cranks. These wei hisY hold the bell crankssmd tam -rods on t at side ofthe erpendioular to w ich they have been movedn by the engagement of arms 62 with either of the cam projections (.53 or 64.

To prevent with absolute certainty the escape of any dust upwardly onto the aides 71 and frame 72, a plate of hard rub er or liber f' is -astcned to ,each temp rod- 14, said plate slidin over a plate 74 secured to and connectin e lower ends of the frames 72 and exten mg across the machine, plate 74 being provided with n. slot wide enough to lpermit the tamp rods'to vibrate backV and forth. Each plate 'f3 1s of a width ual to the distanoe'from center'to center o adjacent temps, so that the plates of adjacent temps touch .each other. Thus the opening in plate 7e is constantly sealed and Ezio dust can riseto the level of the guides The lower endy of the hopper 12 is provided with individual tunnels 80, one for each tnmp-rod. Theseiunnels are formed in a frame 81, which extends entirely across the machine and is provided with side flanges 82 bolted to side flanges 83' on the hopper 12. Beneath the funnels 89 are nipples 84 suspended'from a plate 85 extending across the machine. This plate is bolted to flanges `8G on the' funnel-frame 81, the iianges 486 extending downward beneath the plate 85 at one side and at both endsof the machine.

The main advanta of a machine embodying thc features ereinbefore described may be enumerated as follows: 1. Capacity for proper oilng of the temps, which is impracticable where the :trictional driving mechanism directly-engages the temp rods. 2. Stroop frictional grlp lpon the tamps by means o the tapering we ges, thereby 'ving eater lifting power to the temps an h 'here fore, and actuating them more osi- ;tively' on the up stroke than the own stroke. 3. A positive stroke of deiinite distance on the initial down-stroke of the temps, whichhas been referred to hereinbeyfore. 4. Econom of ower in drivin the =machine, as it is c ear tliat the rocking rum Loan be actuated with less power than a re ciprocatin bar directly engaging the tamp rods.V V5. limination of the stirrers in the hopper, their function being performed with Iequal eiiicacy and more safety-- by the vi -bratory movement imparted to the tamping rods. 6.-.Absolute control of the density ,.'with which the powder is packed into the shells by the adjustment of the springs 26, thereby enabling the )aching of cartridges of any weight and o uniform wei' ht. 7. The provision of individual :tunnels or each temp, and the arrangement whereby quick changes can be made from one size of nipsie to another, thereby enabling shells of ifi'ercnt sizes to be punched without substantial dela in changing from one size to another. 8. e provision of means to prevent dust from rising from the hopper to the mechanism above the same. Having now fully described my invention, what I claim and desire to protect by Letters Patent is:
