Description

A shell magazine and loading device for artillezy Matatjahu 42102 2 invention relates to a shell magazine and loading In my patent application Serial parent in connection with which the present application is for a patent of there is disclosed a shell and loading device fo artillery a shell storage enclosur which is upwardly inclined respect to the shell retaining means associated with the enclosure for releasably retaining each of the shells in the enclosure against downward displacement under a shell unit substantially horizontally at a lower end of the enclosure and into which a lowermost located in the enclosure is adapted to fall when the retaining means retaining the shell is shell displacing means associated with the shell receiving unit fo displacing a shell located in the unit into a actuating means coupled to the retaining and displacing means for actuating and deactuating the retaining and displacing in accordance with a predetermined Such a magazine and loading device hereinafter be referred to as a shell and loading device of th As indicated in the specification of the parent th but not exclusive application of the and device of the kind is in the case of substantially horizontal or near horizontal position for Whilst it is clearly that the magazine device of the kind specified also applicable to artillery in general and mortars in particular having conventional one piece clear in the specific embodiment described and illustrated in the specification of the parent patent the use of the device described Involves the lowering of the one piece to a substantially horizontal position even where this possible with conventional the location of the device at the of a substantially horizontally barrel requires the provision of a considerable amount of space this may not be readily available on an armoured with a device of the specified specific displacing means have to be provided for displacing the shell located in the shell receiving unit into It is therefore an object of the present to provide a modification of the device of in above referred to disadvantages are substantially avoided or According to the present invention there provided a modification of the shell magazine and device of the kind specified within the shell storage enclosure and unit are mounted on a support bracket which is plvotally displaceable between a lowermost position and ah uppermost position in which the is substantially aligned with barrel he latter i 4 With such a the barrel is not lowered to a substantially horizontal position but is rather lowered from its normal position to its normal loading position in which it is still elevated with respect to In this position the shell receiving supported by the support bracket is aligned with the slopes The shell after being released from the shell receiving unit can pass into th barrel substantially under the of its own weight and the provision o specific shell displacing means can be wholly or largely dispensed by virtue of the act that the barrel remains an elevated position during the overall space area of required to accommodate th artillery mortar and the loading device is substantially reduced as compared with the requirements when the barrel would have to be lowered a horizontal position and as indicated above of significant advantage where the mortar is carried by an armoured In order to avoid the Inherent in manually raising the shells for introduction into the raised magazine the support bracket as a pivotable betwee an upper position in which the shell receiving unit is located adjacent the mouth of the barrel and position in which position shell can introduced into the magazine with a minimum amount of Displacement of the support bracket between its uppe and lower positions can be effected One embodiment of a mortar shell magazine and loading device in accordance with the present invention will now be described by way of example and with reference to the accompanying drawings which show schematically a side elevation of such a magazine and device associated with a As seen in the a mortar 1 comprises a barrel 2 which is mounted about an axle 3 with respect to a support plate The latter is slidably mounted on a base plate 5 which is rotatable about a vertical axis A curved cam arm 7 is coupled at one end to the axle 3 and at an upper end to an axle 8 mounted on a collar 9 secured to the barrel A barrel displacing shaft 10 is at one end to a pneumatic displacing mechanism and is fitted at its opposite end with a displacing roller The shaft 10 is furthermore provided with a vertically disposed indicator 10a associated with an elevation scale Mounted on the mortar framework is adjustable stop 10c which serves to delimit the chosen A shell magazine and loading device 12 of construction and operation similar to that shown and described in the drawings and of the parent patent are mounted a support bracket which is in its turn pivotably mounted on an axle 14 journalled in framework integral with the support plate Pivotal displacement of the bracket 13 is effected by means of a traction cable 15 only schematically in the The cable 15 is linked at one end to a coupling position 16 carried by the bracket 13 and at the other end to a coupling position 17 carried by the mortar 6 In operation the mortar barrel is displaceable from its loading position in full throug an intermediate firing position in broken to a maximum elevation firing position in chain dotted The angle of elevation of the barrel is at any time observable from the position of the indicator 10a along the scale Displacement of the mortar barrel between these positions is effected by means of the displacing arm 10 and roller Thus displacement of the 10 and roller 11 to the left hydraulic means or the results in the elevation of the barrel as a consequence of the roller 11 sliding forwardly on the surved cam arm Similarly withdrawal of the arm 10 and roller 11 to the right results in the barrel 10 lowering under its own With the support bracket 13 lowered into its lowermost as shown in chain dotted the magazine can be loaded with shells when the bracket 13 can be pivotally displaced by means of the traction cable 15 into its upright position in full in the shell receiving unit is aligned with the barrel In this position upon release of the lowermost shell the latter slides under the influence of gravity from the shell receiving unit into the barrel If the device 12 can be provided with special shell displacing means such as for example that described in the parent patent so as to assist in and thereby ensure the displacement of the shell from the device 12 into the barrel The displacement of the support bracket 13 can be 7
