Definitions

  • This invention relates to a device for filling and emptying cartridge belts, the device being provided with a displaceable ejector for the cartridges and with a drum for feeding the belt thereto, which drum is controlled by a shaft movable by a displaceable part of the driving mechanism.
  • the invention has for its chief object to provide a device which will ensure a rapid lling of the belts with the cartridges without hindrances which arise especially owing to the incorrect position of the cartridges in the cartridge container.
  • the filling device is provided with means for holding the cartridges in a cartridge container and means for 4 feeding the cartridges to the belt from the bottom of the container.
  • the container is formed at its bottom with a charging space from which the cartridge is pushed into the belt and subsequently a second cartridge is allowed to fall into the charging space.
  • a further feature of our invention is the provision of a shaking means in the container, the movements of which are controlled by the cartridge pushing means as will be more clearly explained hereafter.
  • the filling device according to the invention can be used Aboth for filling and for emptying the cartridge belt; this is eected by altering the path vof the cartridge ejector.
  • This alteration of the path is obtained by means of a simple device which is based on the fact that the slide, on which the cartridge ejector is arranged, is provided with two grooves with which the pin of the crank-drive mechanism engages as required.
  • the filling device according-to the invention is of simpler construction than previousdevices of this kind, cheap to produce, readily operated, light in weight and suitable for transport.
  • Fig. 1 is a longitudinal sectional view with parts in elevation and ofthe cartridge filling apparatus.
  • Fig. 2 is a longitudinal elevational view with portions in section illustrating the position taken by certain ⁇ elements during the feeding of the cartridge into the belt.
  • Fig. 3 shows a similar view with the apparatus adjusted for e'jectlng cartridges from the belt.
  • Fig.. 4 is a cross sectional view taken on the section line IV-IV of Fig. 1.
  • Fig. 5 is a cross sectional view taken on the line V-V of Fig. 2 illustrating the position in which the recess 68 in the shaft I'I is located opposite the lever arm 61 so as to permit adjustment from a charging to an ejecting position or vice versa.
  • Fig. 6 shows a sectional elevation of the holding member for the cartridges
  • Fig. 'l is a plan view of the holding member shown in Fig. 6.
  • I denotes a boxlike base body having feet 2.
  • the drive of the mechanism consists of a crank 5 ( Figure 5) which is keyed on a pin or shaft 6 that is mounted in a bearing 3 in the wall of the box I.
  • a crank 'I Secured to the inner end of the shaft 6 is a crank 'I which is provided with a pin 8 which engages in a groove Il or I2 ( Figures 2 and 3) in a slide I0 that is displaceably arranged on a holder shaft I1 which is rotably mounted in bearings in the side walls of the box.
  • the slide IU is provided with a tubular attachment I3 which is mounted on the hollow shaft I1 that is provided with a helical groove I6 in which a pin I5 on the attachment piece I3 on the slide engages, so that, during the displacement of the slide, the shaft is rotated. Since the crank mechanism is symmetrically arranged, the operation of the device is not altered whether the crank handle 5 is rotated in one direction or the other.
  • a drum 2l for feeding the cartridge belt (not shown) to the device, which drum is provided on the ⁇ periphery thereof with teeth that engage in the individual members of the belt.
  • the shaft l'I is rotated by engagement of a lug I5 with the walls of a cam slot I6 in the shaft Il.
  • the said drum is provided on one end face with teeth 2
  • the teeth are formed in such a manner that they engage when the shaft is rotated in one direction whilst they slip over each other when the shaft is rotated in the opposite direction.
  • a disc 25 ( Figure 1) is mounted on the hub of the drum so as to be displaceable by means of a spring 21 acting thereon.
  • the disc 25 is provided with ⁇ teeth 26 reversely formed stationary teeth secured by and projecting inwardly from the right hand bearing of the shaft I1. These latter teeth are so formed that when the teeth on the tube 22 slide over the teeth 24
  • a cartridge container 30 is removab-ly cons nected to the box I by means of a lever 53 ( Figures '1 and 2) which is rotatably mounted on a, pin 52 andfa projection 54 which engages with ⁇ xed teeth 551-0411vr the. .box I. .Connected .to the cartridge container 39 is an attachment 5I which prevents the cartridge belt from slipping out of the teeth of the feeding drum 20..
  • cartridge container 30 is divided by a vertical wall 3
  • the shaking device which ensures the continuous feedingof the ,cartridges into Vt'l'i'e charging spaces.
  • the shaking device consists Vof' two plates 34 and 35 which vare bent intova ridge-like shape and the bottom parts of which are turne'dtowards eachother.
  • the parts 34 and 35 of ⁇ tl'ie.-s1iakin ⁇ g device are 'provided with hangers by means of which they are 'mounted'on a pin 32 which is mounted in eyes formed on the bottom edge ⁇ of the dividing wall 3
  • Thespike I3 is guided in a guide -4 whiehis'forme'd inthe top wall of thelv box I and which also serves as a guid'eior thev slide I; :Suitable openings are formedinthe 'cartridge containerfor the passa/ge of ⁇ the spikethrough the wall of the box'and the cartridge container.
  • One arm 'of the 4cartridgeholder passes 'into yan l Yopening 5llin the'boX, through which-opening' "the cartridges are pushedj'out of the Ycharging space into the A'cartridge belt,r whilst the other arm is forked, the forked parts vv41 and 41 ( Figures 5 and'l being'bentto form projections 43 'and 448 Lwhich,when the lever is turned, passes Vinto the vcharging'spaces lIIIland 4U ( Figure 4). ⁇
  • the lever 46 is ⁇ loaded by aspring 49 which is.
  • the shaking device ⁇ In the working movement of the vejectors (in the direction 'of thev arrow p), the shaking device ⁇ also comes intooperation, ⁇ since the wedge spike I3', which moves with the slide, passes through the openings injthe boxand the cartridge container 39 and ⁇ strikes the bevelled stop pieces 38 and 39oftheV-parts 3'4 and 35 and moves ythem ⁇ against the action of the spring 31.
  • the spring 31 brings the parts V34 and I35 back into fthei'r original position as soon as the spike I3 comes out of engagement with thern,' -and ⁇ lthis operation, which isfrepeated ron every working lstroke'causes ⁇ the-shaking and the arranging together of the'cartridges, so that Athe latter can be Vfedy continually into the charging Vspace 1without any jamming of Jthe cartridges.
  • the slide I is secured rmly in the position in which the projection 61 is adjusted opposite the opening 68 (in the construction shown in Figure In this position, it is possible to press the arm 64, which pressure results in the projection on the arm 63 coming out of engagement with the opening l0 in the slide I0.
  • the pin 8 of the crank is then brought over into the groove l2 in the slide, with the result that the path of .the ejectors I4 and I4' is prolonged in the direction of the arrow p to such an extent that the pushing of the cartridges out of the belt is rendered possible.
  • the corresponding arm ofthe securing lever drops into the opening in the slide and the filling device is prepared for the pushing out.
  • the groove I2 is curved in a part I2' thereof, as can be seen from Figures 1 and 2.
  • the object of the curved part I2 is to obtain a greater force on the pushing of the cartridge out of the belt, since, as is known, the cartridge is held in the known manner by means of a i groove or by means of the edge of the cartridge by a projection formed in the cartridge belt.
  • the groove I2 may be provided with two curved parts I2 and I2" in order to enable the cartridge ⁇ to be pushed easily out of the belt in the rotation of the crank to one side or the other.
