To all whom it may concern: thebolts after the properbalance is obtained.

Be it known that we, JOHN F. MEIGs, a The slot 1 is open at one end of the case and citizen of the United States, residing at communicates with an opening 8 in that end South Bethlehem, and HERMAN G. JAKoBsto permit the case to be withdrawn without 5 SON, a subject of the King of Sweden, residwholly removing the bolts, and the case is ing at Bethlehem, in the county of Northopen at the inner side to permit the insertion ampton, State of Pennsylvania, have inventand removal of the weights 5 between the cd certain new and useful Improvements in partitions 6, and when the case is in place a Adjustable Balancing-VVeights, of which the pendent flange 9 of the frame retains the 10 following is a specification. weight within the case.

This invention relates to an improvement In the construction shown in Figs. 4 and 5 in ordnance, and has for its object to change there is a single weight 10, which conforms at the balance of any gun pivotally mounted to its upper part to the outer form of the recoil- 6o swing vertically; and it consists in providing cylinders E E, and this weight, which is car- I 5 the gun or its attachments with a support ried on a threaded sleeve N, is movable upon for a weight adjustable thereon, as fully set the support, which is in the form of a screwforth hereinafter and as illustrated in the acshaft F, turning in said sleeve and in bearcompanying drawings, in which ings 12 of the cradle and limited in its niove- Figure 1 is a side elevation of a gun and its ment longitudinally by a head 13 and nut 14,

In the construction shown in Figs. 1 and 3 By providing the gun with a balancing the gun is mounted upon the cradle B, proweight or weights, as described, a prepondervided with the usual trunnions 7, although in ance of weight at the breech or the muzzle carrying out our invention the trunnions and to any varying extent required may be 30 may be upon the gun itself. Connected with secured to adapt the manipulation of the the gun or its attachments, whatever the latgun to the personal equation of the person ter may be, there is a support F, which, as using the same in the case of smaller arms, shown in Figs. 1 to 3, is a flange, the said while with guns of larger caliber, where the support being the means of supporting adelevating is done through the medium of 3 5 justably a balanced weight or weights the pogearing and where the balance varies in acsition of which in respect to the trunnions decordance with the elevation of the gun in tel-mines the extend to which the gun is bal consequence of attachments connected thereanced 0r overbalanced upon its pivots, on with-as, for instance, shields carried by the which it swings vertically. gunthe weight may be adjusted so as to 40 In the construction of Figs. 1 to 3 there is a properly balance the gun when it is in its difseries of weights 5 within a case A, bolted to ferent positions for firing. The adjustable the support F by means of bolts C, which ex weight also permits of the change of balance tend through the flange or support F and required when in target practice. A small- 0 through a longitudinal slot 1 in the top of the caliber auxiliary barrel is inserted in the gun 45 case A, permitting the latter to be shifted in place of the charge. By use of the ballongitudinally to change the balance and to ance-weight also the assembling and mountbe secured in position by turning the nuts of ing of the parts of the gun may be facilitated lll llll in 'i by approximately locating the center of the trunnions without balancing and compensating for any irregularity by adjustment of the weight, so as to avoid the necessity of balancing each gun and cradle together in order to locate the center of trunnions on the cradle.

Without limiting ourselves to balance means and shiftin appliances of any special construction, we 0 aim 1. The combination with a gun pivoted to swing in a vertical plane, of balancing means adjustable to different positions relative to the pivot of the gun, substantially as described.

The combination with a gun mounted to swing on trunnions, of a weight, a support for said weight, and means whereby said weight may be shifted and retained on said support in different positions in respect to the gun,
