Definitions

  • the elevation axis is located as low and as far back as possible. This results in the centre of gravity of the elevating mass, this is to say those parts of the gun mounted for movement about the elevation axis, lying forward of the elevation axis. Consequently, the rapidity and ease of laying of the gun in elevation is adversely affected unless some counteracting mass is added to the elevating mass behind the elevation axis. Such an added mass however increases t-he total Weight o-f the gun and reduces its transport and handling qualities.
  • the present invention provides a field gun mounting in which the weight of the gunner can be utilised for balancing the gun about the elevation axis and also takes account of the fact that the weight of a gunner' is more than is required for this purpose.
  • the invention therefore comprises a field mounting for a gun of which the centre of gravity of the elevating mass States Patent G M lies forward of the elevation axis and having a gunner support pivotally coupled to the elevating mass to apply thereto, rearward of the elevation axis, at least part of the Weight of a gunner, and, according to the invention, spring means are provided to apply to the elevating mass a lmoment acting'about the elevation axis in the same direction as the weight of the elevating mass to counterbalance the applied weight of a gunner.
  • the moment applied by the spring means is adjustable so that the total moment acting in opposition to the gunners applied weight can vbe varied to suit the weight of a particular gunner and so bring any out-ofbalance moment to within a range of values permitting the gun to be easily layed in elevation.
  • FIG. l shows a eld gun and its mounting, in plan
  • FIG. 2 shows, in schematic form, spring means for applying a moment to the eleva-ting mass of the gun of FIG. 1.
  • the gun illustrated is an automatic gun 'having a barrel 1 carried in a mounting comprising a cradle 2 pivoted about ⁇ an elevation axis X-X on a training sub-frame on a carrier base 3.
  • the cradle 2 is provided with hand grips respectively having a trigger, for rng the gun and a control lever for friction brakes, for the training subframe and the elevating mass, which hold the gun on aim during firing.
  • the carrier base 3 is provided at the front with a pair of lfeet 4, which are vertically adjustable to enablel the carrier base to be supported in a horizontal position on uneven ground, and at the back with a pair of long outwardly-diverging and rearwardly-extending spades 5 having blades 6 at their outer ends which engage the ground during tiring to prevent rearward movement of the carrier base.
  • the spades 5 and struts 7 can be folded together to for-m a two-bar and the carrier base 3 may be provided with wheels (indicated in broken lines) for transport purposes.
  • the linkage 11 upon which the couch 1-0 is suspended is constructed so that, during firing, it, and the couch, follow aiming movement of the gun.
  • the linkage 11 upon which the couch 1-0 is suspended is constructed so that, during firing, it, and the couch, follow aiming movement of the gun.
  • adjustable spring means In order to bring the out-of-balance -moment to Within a range of values permitting easy laying of the gun, adjustable spring means, indicated generally at 13 in FIG. 1 and illustrated more fully in FIG. 2, are provided between the cradle 2 and the training sub-frame carrying the cradle trunnions.
  • the spring means are arranged to apply a moment to the elevating mass in the same direction as the moment therein due to the Weight of the elevating mass so as to oppose the excess weight of the gunner.
  • any small remaining unbalanced moment can be held by a friction brake 14 for the elevating mass.
  • the adjustable spring means include a crank 15 mounted on ball bearings 16 for pivotal movement about a pivot 17 on the cradle 2 and a compression spring 18, located in a spring housing 19 mounted on the cradle 2.
  • the force of the spring is applied tothe crank through a plunger 21 slidably mounted in the spring housing, one end of the housing being pivoted upon the cradle at 20.
  • the forward end of the plunger is forked and carries a roller 22 engaged within an adjuster fork 23 slidable lengthwise along a channel in a radial arm 24 of the crank 15.
  • the -adjuster fork 23 can be moved along the ch-annel of the arm 24 to vary the effective distance between the pivot 17 and the axis of the roller 22 so as to vary the throw of the crank.
  • reaction arm 25 Carried by the crank arm 24, for rotation therewith, is a reaction arm 25 which transmits the force of the spring 18 Ito an elevation brake drum casing 26 which is coaxial with the elevation axis X-X and is secured fast to the training sub-fra-me.
  • a roller 27 at the outer end of the reaction larm 25 is engaged in a slotted lug 28 on the casing 26 to anchor the reaction arm 2S with respect to the elevation axis.
  • the relative positions of the pivots 17 and 20 and the lug 28 are such that the force of the spring 18 applies a moment to the elevating mass acting, about the elevation axis, in the same direction as the moment due to the weight of the elevating mass itself.
  • the value of the moment applied by the spring means 13 is dependent upon the throw ⁇ of the crank, that is to say ion the length of the lever arm between the pivot 17 and the axis of the roller 22.
  • the throw, and therefore the moment due to the Spring means is at a maximum with the roller 22 positioned as shown in FIG. 2, and at a minimum when the roller 22 is adjusted to lie as close as possible to the pivot 17.
  • a gunner positions himself upon the couch L? so as to he able to aim through the sight 12 and then adjusts the throw of the crank 15, for balance, byl
  • the characteristics of the spring 18 and the dimensions of the spring means 13 are ⁇ so designed that, after setting of the throw of the crank, any change in the counteracting moment due to the gunners weight as a result of a change in the elevation of the gun is closely followed by a corresponding change in the moment applied by the spring means so as to maintain the sum of the moments acting ion the elevating mass Within an acceptable out-of-b alance ran ge.
  • the angle between the crank arm 24 and the reaction .arm 2S could be made adjustable.
  • a field gun mounting comprising a gun and a cradle lforming an elevating mass of which the center of gravity lies forward of the elevation axis and gunner support means pivotally coupled to the elevating mass to apply thereto, rearward of Ithe elevation axis, at least part of the Weight of a gunner on said support means;
  • said improvement which comprises spring means to apply to the elevating mass a moment acting aboutthe elevation axis in the same direction as the weight of the elevating mass to counterbalance the applied weight of said gunner, said spring means comprising acrank pivoted on said elevating mass, said crank having a rst arm and a second arm, and a spring mounted on said elevating mass and operatively connected to said rst arm, said second arm being pivotally connected as a reaction arm to a relatively iixed part of the mounting.
  • a eld gun mounting according -to claim 2 said first arm having .a channel therein, a fork constituting said adjuster member and slidable in said channel, screw means for adjustment of said fork along said channel and a roller journalle-d in said fork bearing in said channel and forming part of said means pivotally interconnecting said plunger and said fork.
