To all whom "it mag/concern: A

Beit known that I, HowAnn DOUGLAS Hoven, works mana er of Waltham Factory, Nobelv-s Explosives o., Ltd.,a citizen of the residing at Joyce House', Waltham Abbey, Essex, England, have invented a newv and useful Improved Cartridge-Making Machine, of which the following is a specification.

an imlproved 'cartridgemaking machine especia y. suitable Vfor insertiugthe primers into the shells or cases.

. In a machine constructed in accordance with lthis, invention the cartridge shells are fed-,head downward to a rocking segment or arni- Awhich .inverts them by-turning them arounda on the edge of their rims and,

rdrops them' kdown onto supports or pins standingjupfrom. a horizonta Wheel which isrotatedste by ste rier aboveif. `e wheel is provided wi the primers by means of which are' .delivered to the shels onzja rocking shaft.

Fi 11 i's-a sectional plan showing pulleys and carryinga rope ulley a1 from w4 ich a rope a? asses to a p ey a3 on a second'shaft a* which by bevel gear a5 (see Fig. 4) drives a vertical spindle a from which a rope a7 drivesthe vertical shaft b1 of a horizontal disk b adjacent to aj fixed table b2 uponjwhich the shells 1 are placed. .Owing to the weight of their heads they may be readily placed in a vertical position their Aheads downward u on this table iwhich may be slightly incline so thatthey be thel more readily' pushed onto the Theobject'of this invention is,to provide A reciprocatin car# thel machine embodying my invention is friction' collars "allow slip j 3.an'd 4--are sectional elevations at rig t an les to Fig. 2. Fig. 5 is a plan, .6 an en view and Figs. 7 to 10 are .detail views of the mechanism for inverting the disk b which in its rotation carries them around to the funnel shaped mouth of a guide way b3 near which mouthmay be situated an irregularly toothed 'Wheel b* rotated by a rope drive b5 (see Figs. 1 and 4) in the same sense as the disk so as tomove back some` of the shells and prevent jamming. Shells which get too vnear the centerA of the disk to enter the guide way are carried around until they meet an inclined fence b6 which causes them to move out toward the circumference of the disk so' that they may enter the guide as they again come around. The guide narrows down until there is only room for one shell' to pass at a time and the shells are thus fed one by one head downon a rocking shaft d2 having on it friction collars d3 between which is gripped a pinion d? gearing with av rack d? which recelves a,

vertical reciprocating 'movement from a yoke d on a cam d on the vshaft a. The Y to take place should jakshell et jammed. Onl the shaft'd2 is an arm d8 w 'ch comes against adjustable stops d (see Fig. 7 which isa section on the line 7-7 Fig. 5 by' which the anle through which thev sha -is rocked 'by' t e reciproeating rack can' be accurately defined.v The.

segment d has on it a piece 19V which, as the Y segment rocks, comes against the open end of the shell 1 and turns it over, the head of the shell being temporarily retarded by a stop c2 -on the platform c. The segment d thus comes in front of the foremost shell of the l*column in the ide' way and prevents vfurther movement t ereof until the segment has returnedV to its back position when an other shell is pushed out onto the platform c. The shell is ythus by th'e movement of the segment, turnedaabout a point on the edge-of its rim or 'about the stop c? and inverted, the

piece d1? being curved at du in order that 1t may not catch against the rim of the head .(see Fig. 6).A This movement of` the shell is also 'controlled by a -iiange c3 on the wall c1. As soon asthe head of the shell has turned around the stop c2 a presser foot e working a slot c* inthe wall clcomes down upon then free to rock about its pivot i,

the head and presses the shell down onto one of a number of pins f standing up from the face of a Wheel f1.

On a connecting rod a8 from cranksga9 on the shaft a, is a tool carrier g which slides in vertical guides gr1 and pivoted to which at e1 is a lever fulcrumed at one endon the frame at e2 while its other end is linked by a link e3 to the top of the stem ei of thc presser foot e, so that every time the carrier g descends, that is once every revolution ofv the shaft a, the presser comes down 'and presses a shelly down onto a pin f. At the bottom of the wall c1 are two spring stops 05 u on which the shell rests until the pressure of) the foot e forces it past them.

A step by step movement of rotation is imparted to the wheeL f1 as follows A lever]c2 (see Fig. 2) fulcrumed on the frame at f3 is rocked by a crank pin f4 on the main shaft a and by means of a link f5 moves a slide f6 to and fro in horizontal guides f7. To this slide is pivoted a pawl f8 (see Fig. 11) adapted to engage recesses f" cut on the periphery of the wheel f1, a spring flo bringing the pawl into engagement. The wheel is pressed down onto thebed of the machine by a friction spring fn which prevents backlash. Should it be preferred to insert the anvil and primer separately, the anvil is now inserted by the operator. As the wheel rotates the shell comes beneath an inspecting punch or arm l1. sliding in the carrier g. This punch is so set that the head of a cartridge prevents it from moving with the carrier lfor the last part of the travel thereof but should a pin upon which no shell has been placed stop beneath the punch h, there is nothing to arrest the ,movement of the punch and a lug k1 "upon it comes against a segment z' (see Fig. 3) and turns it on its pivot 1 thus pushing in a pin 2 which in turn pushes in a lever i3 toward the right as seen in Figs. 3 and l2 against a spring plunger 4. This movement brings the lever 3 from beneath a fixed shoulder 5 and t is onnected to this lever is a link 7 constantly pulled upward by a spring 8, thus when there is no shell on a pin this l-ink rises and .moves an incline i into the path of a projeetion 1 on the shaft and so disengages a clutch (not'shown) and stops the machine. The machine may also be stopped when desired by the hand lever and links jl connecting it to the lever 3. At the next two stops of the wheel f1 the shell is beneath punches lc 7:1 the first of which clears and sizes the pocket in the head of the cartridge which is adapted to receive the primer while the second clears the communication hole at the bottom of such pocket. The shell now arrives at the point Where the primer is inserted. The primers are laced head downward on a tabl-e Z from which they are pushed onto a disk Z1 similar to the disk b rotated by a rope drive al from the spindle a6. Thedisk feeds the primers into a guide way Z2 following which'they come up against a stop Z3 which is normally held up in their path by a spring Z4 (see Figs. 13`and 14).

In order to prevent jamming of the primers at the mouth of the guideway Z2 an agitator Z5 may be carried by an arm Z pivoted toV the frame and rocked by a cam ZT on the shaft a4 (see Figs. l and 2).

Bolted to the carrier is a vertical rack m gearing with a pinion m1 ripped between friction collars m2 on a sha t m3 rocking on pivots m4. At m5 two fingers m are pivoted to this shaft and their tips are kept 'together by a spring m7 which embraces them. The tips of these fingers are hollowed out and also beveled so that as they are brought by the rocking of the shaft' into the position shown in Fig. 11 they (first pressing down the stop Z3 against the spring Z4) open slightly, pass down over and grip the primer which is waiting for them. As tlie rack m descends the shaft m3 is'rocked and the fingers are thus turned through two right angles and hold the primer directly over the pocket inthe head of a shell, into- Which pocket a punch n on the carrier now pushes the primer a little way. At the next stop of the wheel -a punch nl pushes it a littleY farther in, and `"at the next stop, a third punch n2 pushes it home. If desired this punch n? may be capable of sliding a small distance in the carrier (see Fig. l5) and may have upon it a finger n3 adapted to contact with an insulated terminal n* fixed to the carrier. a bell are connected to the frame of the machine and to the terminal n4. Should therefore a primer have been missed and a shell arrive beneath punch n2 without its primer, the punch will meet with no resistance and will not move relatively to the carrier, the finger n3 Will thus come into contact with the terminal n4 and a signal will be4 given to the operator. At the next stop, the shell is picked off the pin as follows :-The carrier g carries a tube o at the lower end of which are two weighted aws 01 (see Fig. 16) which can slide in inclined guides 02 0n the tube. As the carrier descends these jaws pass down over the rim of the head of the cartridge. As the carrier rises the jaws retain their hold of the head and the shell is thus drawn off its pin. On the next descent of the carrier the shell held in the jaws comes down onto the head of the next shell and is thus pushed up into the tube, raising any shells that may be in the tube, the tvp one of the column fallin out of the top of the tube An electric battery and into a collecting receptacle. Orthe 'tube may'connect by a telescopic joint with a tube passmgover the machine and dropping the shells into a receptacle placed beneath its mouth. AtA the next step a second inspectr vpunch p may be arranged upon the carrier to descend upon "the head of Should the pickoif have-failed to shell have been left on thek pin the downward movement of the punch is checked, the punch therefore moves relatively to thecarrier and comes against one end of anar-m. p1 (see Figs. 3 a-nd 12) pivoted to the vcarrier at p2; the other end of this arm is .thus caused to press upon the segment d and the machine stops as already explained. v a
