lrluNlTElv STATE Patented Jul 12, 1932 AIMO JoEANNEs LAHTI, or JYVASKYLA, FINLAND "CARTRIDGE CASE Application filed December as, 1930, SeriaI No. 504,925 and in Finland July 5, 1930.
The present invention relates to such a car tridge case for fire-arms, which inserted in the feeding aperture of the fire-arm automatically feeds the Cartridges into the weapon. The cartridge case according tothe invention is preferably made in the shapeof a cylindrical container, inside oflwhich the car tridges are arranged either in a cylindrical or aspiral guiding channel side by side and parallel to the axis of the container. A spring acted feedingdrum, fitted in the guiding channel, feedsthe cartridges intothe feeding chamber at the periphery of the case.
- Theinvention comprehends also an indicator,
the case.
whichindicatesthe number of cartridges in the case and is depending on the motion of The accompanying" drawings illustrate schematically some ways ofcarrying out the invention in practice, andin it: i y Fig. 1 shows the end view ofa so called single row cartridge case according to the i moved.
invention, ftheycoverbf the case being re- F 2 shows in side elevation a section on center line of the above case. The key of the case is'shown inserted in place.
"Fig. 3 shows thekey of the case as seen fl. ram below.
the invention.
Fig. 4 isan end view section of a so-called The single row case according to Fig. 1 is made up of a round case 1, to the axis of which is fixed at its flange 2 and by means ofscrews or rivets 3 the case shaft 4 extending throughout the length of the case. Inside of the case 1 rolls on said shaft 4 the feeding drum 5 on the periphery 7 of which i there is a flange 6. The guide channel 8 for the cartridges is built up of the case 1, the
The operation proper of the cartridge case should be clear from the above. By action of the feeding spring 10 the feeding drum 5 r0- tates counter-clockwise the feeding shoulder ll pushes the cartridges 12 into the feeding chamber 14 from where these are fed further into the cartridge chamber. 1
The filling of the cartridge case is carried out as follows: When the case cover 9 is removed the guiding groove 8 is freely accessible. The case key 16, shown in Figs. 2 and 3, which is furnished with a joint handle 17 8 as per drawings, or of some other suitable construction, is pushed into the case in such a way that the case shaft 4 sticks into a centric bore 18 of the key 16. The pins 19 in the key 16 engage corresponding holes 20 in the feeding drum 5. At the end of the shaft 4 there is a sprocket wheel2l, which-is engaged by a latch 22 pivoted into the key 16, said latch 22 being pressed againstthe sprocket wheel 21 by means of a spring 23. l/Vhen the feeding drum 5 is turned clockwise, by means of the key 16, the feeding shoulder 11 moves along the guiding channel 8 in the direction of rotation until it strikes the guidthe spring 10 from bringing the feeding drum 5 back as long as the key 16 is retained in place. The, cartridges 12 are arranged ing drun1'5' to the side by side in the guiding channel 8. When the key 16 isremoved from the case 1 the feeding spring presses, by means of the feeding drum 5 and the feeding shoulder 13, the row of cartridges against the feeding chamber lt. The cartridge case is ready tobe fired as soon as the case head 9 is now in place. p 7
- The construction principle of the cartridge case according to the modification illustrated by Figs. 4: and 5 is analogous with thatdescribed above. The principal difference is that there are two guiding channels radially arranged but so thatthey join from a single continuous lrregular spiral channel 8. 'Tl'llS channel 8 is made up by the partition- walls 7 and 26 in the case 1 and the case cover 9.
The feeding drum 5 on the case shaft 4 is rotated by the feeding spring 10 around the shaft 4; the spring 10 tending to turn the drum 5 counter-clockwise To'the periphery of the feeding drum 5 there is fixed a small stirrup 27 in which a feeding lever 29 is pivoted 'on the pin 28. At the end of the lever 29, extending through'the clearances 30 and 31 between the partition-walls 25and 26 up to the outer feeding channeh there is a feeding cylinder 32 shaped in theform of the cartridge, the length of which is iIiEXCESS of the thickness of the feeding lever 29 which is only slightly narrower than the clearances Y31 and 32. r v
The cartridge case is filled in the way de scribed above i. e. by removing the cover 9 and setting by means of thecase key 16.'
the pins,19 "of which fit into corresponding holes 20 in the bottom of the feeding drum 5,
the feeding spring 10 and locking the feedshaft 4 of the case 1. The cartridges 12 are arranged side by side in the feeding channel '8, when the cover 9 is now pressed into place and the key 16 removed.
the feeding spring 10 forces,- by means of the feeding drum 5,, the'feeding lever 29 and the feeding cylinder'32, the cartridges 12 into the feeding chamber 14 at the periphery of v the cartridge case 1, from which chamber 1% cartrid e case 1 there is a hole 38 facin the 1 feeding drum 5 the saidhole being matched by figures in the feeding drum bottom in such a way that the figure appearing in the hole 33 shows the number of cartridges still left in the drum. I
7 It is of course possible tomake modifications in details within the scope of the invenoted upon the outer periphery of said drum pivoted upon" the outer periphery of tion while still keeping to its principles. It
is for instance possible to increase the turns of the spiral cartridge channel 8 in order to house a greater number of cartridges 12 by increasing the diameter of the case. The guiding channels may also be arranged helically, in which case there must be a joint in the feeding lever 29 which allows the lever to swing also in' the direction of the axis of thecase. I. laim? g,
'1. A cartridge magazine comprising a cylindrical case, a feeding drum mounted in said case of smaller diameter than said case thereby forming cartridge channel, and a rigid arm pivoted upon the outer periph-' cry of said drum for feeding thecartridges insaid channel. I
2." A'cartridge magazine comprising a cylindrical case, a feeding drum mounted in said case; of smaller size than 'said case, a spiral cartridge channel formed between the outer'periphery of said drumand the inner periphery of said case, and'a rigid arm pivfor feeding thecartridges in said channel.
3.,A cartridge magazine comprising a cy- I -lindrical case, a feedingdrum mounted in saidcase of smaller. diameter than said case, partition walls upon said case, located between the outer periphery of said drum and the inner periphery of said case, a slot provided in said partitions, and a rigid a'rm said drum adaptedfto extend through the said slot inorder to feed the-cartridges insaid channel. '7 4. A cartridge magazine comprising a cy-- lindrical case, a shaft upon which said case is, mounted, a feeding drum rotatably 1 mounted upon said, shaft within said case, a ratchet wheel upon said shaft, a key member havinglugs adapted to cooperate with said drum, a pawl carried by said key mem her for cooperating with said ratchet wheel, a spring secured to said shaft andtosaid drum for rotating the same in order to feed cartridges, said key being adapted to maintain said drum in locked position against the action of said spring for loading said magazine with cartridges. r
