ARTHU'B. TREVOR DAWSON AND GEORGE THOMAS BUCKHAM, OF WESTMINSTER,

LONDON, ENGLAND, ASSIGNORS 'IO VICKERS LIMITED, OF WESTMIN STER, ENG- LAND.

PERCUSSIVE FIB/ING MECEANISM OF BREIGH-LOADIN G GUNS.

To all 'whom it may concern Be it known that we, ARTHUR TREvon Dawson, knight, and GEORGE T I-ioMAs BUCK- Imir, both subjects of the King of Great Britain, residing at Vickers House, Broadway, festininsteig in the county of London, England, have invented certain new and useful Improvements in or Relating to the Percussive Firing Mechanism of Bi'eeCh-Loading Guns, of which the following is a specification.

This invention relates to percussive firing mechanism for breech loading guns, of the kind in which the striker is released by a trigger or firing handle mounted on the gun carriage.

rI'he chief object of the present invention is to provide improved means whereby the triggei' or firing handle can be mounted on a part of the carriage which is not co-axial with the gun trunnions, and the operative relationship between the said trigger or handle and the striker can be maintained notwithstanding the movements of the gun in elevation or depression.

According to this invention the gun cradle is provided with a pivoted device suitably connected with the iring shaft and having a curved surface with which the trigger or firing handle, or a part moved thereby, is capable of engaging at any elevation of the gun to transmit movement to the firing shaft and thereby re the gun.

In order that the said invention may be clearly understood and readily carried into effect, we will describe the same more fully with reference to the accompanying drawings, in which Figure 1 is a side elevation of a portion of a gun mounting provided with a constructional form of the improved firing mechanism, the gun being in its horizontal position. Fig. 2 is a plan of a port-ion of Fig. 1, and Fig. 3 is a view similar to Fig. l showing the gun elevated to an angle of about 70 degrees. Fig. 4 is a view similar to Fig. 1 showing a slightly modified form of the mechanism. Figs. 5, 6 and 7 are respectively a side elevation, a partial sectional plan, and a rear elevation showing a constructional forni of the invention in which the trigger is carried on the handle of the elevating hand wheel or lever. Figs. 8 and 9 are respectively a side elevation and Specication of Letters Patent.

Application led October 18, 1913.

Serial No. 795,854.

a sectional plan showing a further application of the improved firing mechanism.

A. is the gun, B the gun cradle, B one of the trunnions and C the gun carriage.

D represents the aforesaid device which is pivoted at d to the cradle. D is the trigger or firing handle and D2 the firing shaft.

E is the elevating handwheel or lever which is omitted from Figs. 5 and 8.

In the examples shown, the aforesaid device D is in the form of a curved plate the pivot d of which is arranged parallel to the trunnions and in front thereof when the gun is horizontal. The firing handle D is in Figs. 1 to 4 pivoted at d on the carriage C, preferably (as shown) at-a point behind the trunnions. A. roller d carried by an arm of the said handle bears against either the front or, as illustrated, the rear surfaces of the said curved plate D. The curvature of the plate when the latter is in its normal position is concentric with the trunnions. iieeted either directly as in Figs. 1 to 3 or through a two armed lever as in Fig. 4 to a. connecting rod D2 (constituting the aforesaid firing shaft) carried on a guard plate attached to the cradle, the rear end of this rod being pivoted to a link cl2 which lies in loose contact with an arm Dc on the gun; this arm is suitably connected with the seai of the striker. The rod D2 has a spring D2x which serves to hold the plate D in contact with the roller clx. The said curved plate is shown in Figs. l to 4 as being for convenience of construction in the form of a ring or disk, and the tiring handle is disposed in a convenient position contiguous to the elevating hand wheel E.

The aforesaid pivoted device having a curved surface, instead of heilig in the form of acurved plate, ring or disk as aforesaid, may7 be modified in shape in order to adapt it to the requirements of the particular form of mounting with which it is to be employed.

In the construction shown in Figs. 5 to 7 the firing trigger D is carried on the handle of the elevating handwheel or lever E which is mounted on the gun carriage. The said trigger operates through the known arrangement of a sliding pin d3, a lever cl3* and another` sliding pin (Z4 upon an arm di* on a The curved plate mayv be eonvertical shaft (Z5 mounted on the carriage. This shaft has another arm c 5X that carries the aforesaid roller (Z. The rod D2 connected to the curved plate D operates upon the arm DX on the gun in a similar manner t0 that described with reference to Figs. 1 to 3.

In the construction shown in Figs. 8 and 9, the rod D2 is connected at its rear end to an arm D3 which carries a bevel pinion DSX gearingivith a similar pinion forming part of or connected to'a sleeve D. This sleeve is mounted on the cradle and carries a plunger' D5 which is adapted to engage with a sleeve D5X carried by the gun, in a similar manner to that described in the prior British specicatiouNo. 16216 of 1911. In the example shown in Figs. S and 9 the rod -D2 is displaced, from the trigger D on the elevating handwheel or lever in asimilar manner toV that described with reference to Figs.

., 'lelie curved plate D in the constructions Figs.E 5 to 9 differs slightly from that of Figs.; 1 to -l in that it is not a colnplete ring. t That lWe claim and desire to secure by Letters Patent of the United States is 1. Iny percussive firing mechanism for ordnance, the combination With aA noirelevating part of the mounting and the gun cradle, of a ,firing device mounted on said non-elevating part, a curved member moved by said device and pivotally mounted on the cradle in co-axial relation with the gun trunnions, a striker releasing member on the gun, and a connecting rod pivoted to said curved member and serving to transmit the pivotal movements of said curved member to the striker releasing member on the. gun.

2. In percussive firing mechanism for ordnance, the combination with a non-elevating part of the mounting and the gun cradle, of a firing device mounted on said non-elevating part, a curved member moved by said device, a pivot for said member carried by the cradle and arranged parallel to the gun trunnions, a striker releasinginem` ber on the gun and a connecting rod pivoted to said curved member and serving to transmit thel pivotal movements of said curved member to the striker releasing member on the gun.

3. In percussive tiring mechanism for ordnance, the combination with a non-elevating part of the mounting and the gun cradle, of a firing device mounted on said non-elevating part, a curved plate moved by said device, a pivot for said plate carried by the cradle and arranged parallel to the guntrunnions, a striker Areleasing member on the gun and a connecting rod pivoted to said curved plate and serving to transmit theJ pivotal movements of said curved plate to the striker releasing member on the gun.

et. In percussive iii-ing mechanism vfor ordnance, thecombination with a non-ele-A vating part of the mounting and the gun cradle, of a tiring device mounted on said non-elevating part, a curved plate moved by said device,a pivot for said plate vcarried bythe ,cradle and arranged. parallel to the gun trunnions, a striker releasing arm on the gun, a iever in contact With said arm and a. connecting rod pivoted to said lever and tothe curved plate. l E
