SPECIFICATION forming part of Letters Patent No. 494,905, dated Apr-i1 4, 1893. I

Application filed May 26; 1892. Serial No. 134,476.- (No model.)

To all whom it may concern: Be it known that I, ARMIN TENNER, engineer, a citizen of the United States of America,

residing at 13 Grossbeerenste, Berlin, in the German Empire, have invented new and useful Improved Oartridge-Loadin g Machines, of

which the following is a specification.

The subject matter of the present invention is a cartridge loading machine having a step like movement of the rotary table with its clamping bearings in 'which the'cartridge casesare' held and are successively. brought beneath the tools or loading devices so that by each simultaneous operation of the same a cartridge is completely loaded. A device is combined with the rotary table consisting essentially of radially movable slides in order to bring felt wads cut out by hand or machine over the mouths of the cartridge cases at the moment when the same come beneath the punch immediately following the powder charging device. The same device can also be used for loading ball cartridges.

The invention also includes gearing for the rotary table: a reamer in connection with the powder charging device; a shot measure a device for upsetting the edge of the cartridge case and the well known devices for cutting, stamping and inserting the upper wad.

Figure 1 is a side view of the cartridge loading machine for shotcartridges. Fig. 2is'a vertical section; Fig. 3 a top view partly in section. Fig. 4is a part horizontal section showing the clamps for the cartridge cases in top view. Fig. 5 is an elevation of the tool carrier in its lowest .position, five cartridges being shown in section to demonstrate the operation of the parts. Fig. 6 is a section of thelast tool for upsetting or turning down the edge of the cartridge case,

plate A and two standards B B connected by v a yoke C, the tool carrier D being guided in prismatic or other guide ways in the arms of the same. To the front 'of and beneath the tool carrier D, which moves vertically, is a feed wheel or rotary table E in the center of which is the fixed standard A which carries a stationary plate A Between the standard A and the conically borednave E'- of the rotary table E is an exteriorily conical annular member- F which can be so adjusted by means of screws 1) q that a considerable friction can be produced on the surface of the nave in order to prevent all independent rotation of thetable E under the impulse of the ratchet and pawl driving device. The movement of this device is in common with the stroke of the tool carrier D, derived from the horizontal shaft G. which is driven by appropriatestraps or in other suitable manner. The eccentric a with eccentric rod 1) which is in connection with the slide (1 with spring pawl c serve to transmit the movement of the shaft G so that the ratchet wheel 6 connected to the naveE of the rotary table E receives its intermittent movementduring each semi-rotation of the shaft G. The tool carrier D is reciprocated in vertical plane by thesame being connected by the rod H to. the crank I of the shaft G (Fig. 2). I

The circumference of the, rotary tableE or the edge of the upper plate of the samea'nd the annular part E beneath the same is, as will be seen from Figs. 2 and3 so recessed to form the part of a cartridge bearing 11, that the cartridge cases can be inserted from the exterior to be transported under the various tools during the rotation of the table E.

The number of recesses 2' correspond with the number of teeth in the ratchet wheel 6 each recess corresponding with a clamping leverj movingaroundthe fulcrumj within the rotary table E and operated by means of a suitable springf.

The flange U arranged at appropriate height above the base plate and. running almost entirely around the same serves to support the transported cartridge cases so that the same cannot fall out until they reach the open space Z where as is shown in Fig. 4 the flange is interrupted so as to allow the finished cartridge to fall out ofthe machine. The clam ping lovers] are held open for a part of their travel and the action of their springs over- :00 come by the shorter arms of the same, which carry antifriction rollers j coming into contact with an extension u of the flange U which runs from the opening Z to the point toward the tool carrier, the clamping levers:

are always closed as the flange U lies lower than the way described by the antifriction rollers j so that the springs f can press the I bent ends of the levers j onto the cartridges.

After the cartridge cases have beenplaced 1n the open bearings and the clamping levers have securely gripped the same they are su'ccessively transported beneath the tools carried'by the tool carrier, the distance of the same from each other being determined by the distance of five successive cartridge cases 1, Q, 3, 4, 5 from each other.

The first device which comes into'operation is the powder charging device attached to the powder receptacle N. The construction of this device is similar to that described later on for the shot charging device and for the reame'r or Widener. The latter device serves to restore any cases, which may have become irregular, as to correct'form before charging same, and consists of a conical tubular spindle 'm attached to one of the sides of the plate D. Figs. 1 and 5, and fitting over the lower end of the powder-feed tube 11.. By partially inserting this conical hollow spindle in the mouth of thecartridge case, the mouth of the same is cylindrically enlarged during the charging of the case with powder.

' The punch 0 is the second device which comes into operation on the tool earrierD descendingin order to force a felt wad 7', cut out by means of a special device, into the cartridge case (2) already charged with powder.

' On the platePai-e placed a series. of wad carrier slides s radiating from the center of the table, each provided with a ring shaped receptacle .on the outer end to hold the wad, as

shown in Fig. 2, where the slides are in sec-- tilon, and in Fig. 3, where they are shown in p an. These slides are operated to present the wa carried thereby to the cartridge at the proper time and place, by aj cam groove s in the under face of the plat'e A, the shape of which groove is shown in Fig. 3, into which extends rollers s projecting from the upper surface of the said slides... The groove is circular except at one point where it diverges outwardly and this causes the slides in the rotation of the plate P to follow the course of the groove which thus at the proper time advances the slide to present the wad. The spring stop 0 is clearly shown in Fig. 5, right hand side; so

that as soon .as a cartridge case during. the

rotary movement of the table comes into the position 2 the tube s ontheslide s will be over the mouth of the cartridge case so that the punch 0 can drive the wad inthe tube s onto the powder charge. ,In'the third position or above the cartridge 3 (Fig. 5) is the stationary tube-w of the shot measurer. The

The wads are fed to the slides by hand.

in all essential points with the powder measuring device is provided witha slide D (Fig. 2) which in combination with the plate D is moved vertically between the plate W and the casing W said slide having an inclined opening t and an adjustable piece D in order p to adjust the size of the shot measurer. In the uppermost position of the slide 1), the opening 15 comes into communication with the inclined canal leading from the shot magazine W and receives the requisite charge of shot which on the descent of the parts will be filled into the cartridge (3; by means of the tube or channel 10, As n some cases, especially with large shot, a shot falls partly half into the openingtand would on the further movement of the slide be cut in two, I provide a piece of metal 15' under spring action so arranged that the forward surface willas a rule be flush with the surface of the slide and form a yielding edge. In consequence of an incline on the piece 15 and the continued descent of the slide the superfluous shot will be forced into the space so formed but will by the next movement of the slide at once fall into the openingt when the-same during the upward stroke of the slide comes opposite to the said shot. A modification of this auxiliary device which can be omitted in the powder charging device (N, n) is represented in Fig. 7. In this case the lower surface 15 of the charging canal is made to yield being held by the spring i the bent end of which prevents. the superfluous shot'from falling out. As soon as the cartridge cases are as before described charged with powder and shot with intermediate felt wad the same come beneath'a second punch 0' (position 4) which acts similar to the punch 0 and which firstcuts a cardboard wad out of a suitably transported band and then drives the same onto the shot charge. The ratchet device for transporting the cardboard band or strip and also a stamp 0 attached to the tool carrier, for numberinglthe wad is shown in Fig. 2 and partially in Fig. 3 butbeing well -known to. all versed in the art requires no further description. Both punch 0 an punch 0' are as shown in Fig. 5 yieldingly attached in tubes to the reciprocating toolcarrier so that the blow is not sudden but yielding and thus all undue strain on the parts avoided. In the fifth and last position (cartridge 5 Fig. 5) the new upsettingv device or toolfor bending over the edge of the cartridge case onto the upper wad comes into action and consists of a spindle v with upsetting tool it inserted in the head 22 of the same. The spindle u-has rotary motion and reciprocates vertically and is'attached by the bearings V and V to the frame and receives its rotary movement in any. suitable manner from the mechanism. During the rotation. of the rotary table the spindle is so far raised that the head will be above the way described by the cartridge cases. A spring stop 0 connected tothe tool carrier. will, when the. latterreaches the end of it:

downward hub, drive the spindle or mandrel down so that the notches in the tool 1/. in the' head Q) will press on the upper edge of the.

cartridge case with increasingforce. The pressure in con unction with the rotary motion transmitted to the tool will upset or turn over the edge of the cartridge case so as to I securely hold the cardboard wad above the f to the clamping As soonas the finished cartridge is moved with the rotary table E 'a distance equal to onetooth of the ratchet wheel, the same will fall through theopening Z as. the same is on the one hand no longersupportedby the flange U and on the other hand is releasedfromthe grip-of the clamping lever f, the roller 3" of which lies on the flange U.- It will be seen from the above that the cartridge clamps will be at certain tiinesin open position ready for the insertion of fresh cartridge cases. The new felt wads arealso inserted in the wad holders s of the slide s from this side of the rotary drawn inward. K

At each rotation of theshaft G the machine will deliver a cartridge loaded in five operations whichfallsout at the opening Zinto a collecting receptacle. Figs. 8 and 9 represent the modification -for loading ball or militarycartridges all the essential points of the foregoing machine being employed. The empty metallic shells are fed from a tubular magazine M successively, by means of awh'eel L, undersuitable borings of the rotarytable E the clamping device in this case being omitted. The cartridge shells are raised into the cartridge bearings by a connnecting rod when the borings align said rod being operated bya lever Z and a tappet wheel (Fig. 8) the tappet only being shown. The boringsin the rotary table E'and the wheel L will correspond at each step of the ratchet wheel (Fig. 9). The powder feed is eflected from the opposite side of the rotary table in precisely the same manner as described with reference to Figs. 1 and 7 while the bullets are driven in by a device similar to the wad feed, the radial slides s in this case forming the receivers s for the bullets'which when the same are above the cartridge cases2will bedriven intothe cartridge .eases by the punch 0. 'Plledevices for feeding the shot, upsetting the upper edge, &c.
