SPECIFILCATION forming part of Letters Patent No. 733,166, dated July '7, 1903.

Application filed SJptembeI 5, 1902.

To aZZ whom, Ilium/my concern:

Be it known that we, ARTHUR TREVOR DAWSON,lieutenant of the RoyalNavy and director and superintendent of ordnance-works, and GEORGE 'lnona's Bucunnn, engineer, subjects of the King of Great Britain, both residing at Victoria street, \Vestminster, in the county of London, England, have invented certain new and useful Improvements in and Relating to Field Gun-Carriages, of which the following is a specification.

This invention relates to field carriages or mountings chiefly designed for howitzers.

The said invention has reference to the elevating-gear, which is constructed to enable the howitzer to be readily and quickly moved through large angles of elevation for permitting it to be brought rapidly to loading position when firing at extreme angles of elevation.

We will now describe our invention with reference to the accompanying drawings, in which Figure 1 'is a side elevation, Fig. 2 a plan, and Fi 3 a rear end view, of a howitzer and its carriage constructed in accordance with our invention, one of the carriage-\'-'l1ee1s being removed in Fig. 1. is a front eletion, and Fig. 5 a vertical section taken ap proximately on the line 1 1 of Fig. 4, showing a portion of the elevating-gear on an enlarged scale. Fig. 6 is a side elevation of the carriage, showing a modified form oft-he elevate ing-gear and also showing the spade carried by the forward part of the trail.

In all the figures like letters of refei'ence indicate similar parts. A is the howitzer.

it recoils.

O is the trail.

The elevating-gear comprises an elevatin arm (l, Figs. i and 5, pivoted to a bolt :1, screwed into the left-hand trunnion (1 of the cradle 13, the said trunnion being prolonged through the bearing for this purpose. The said elevating-arm is attached by a pivot-pin i3 is the cradle in which d and a connecting-rod d to the elevatingscrew hand-wheel 1).

pattern provided All the gear of the ordinary with the actuating Serial No. 122,217. \No model.)

outer screw-clamp (l is provided, by meansof which the said arm may be fixed at any angle of elevation upon a slotted quadrant or clamping-arc d", secured end b of the said tagonal or other suitable form to receive a bell-crank lever, one arm, B", of which forms a long rearwardly-extending handle, while the other arm, 1%, carries a spring-b0lt U, by

to the trailside. The outer means of which the gun is locked to the ele- 6o vetting-arm (land through said arm to the elevating-gear worked by the hand-wheel I). An incline is out on a projection d of the elevating-arm (7,, by means of which the bolt 1) is automatically itzer is returned angularly to its firing posi tion, so that the said bolt can under the action of its spring reengage with the elevatingarm and lock the howitzer at the proper angle of elevation. A stop (1 on the elevating-arm (L in a position to rehave the bolt 1) from the lateral stressit' would otherwise experience as the howitzer is brought suddenly to rest in its firing position by actuating long handle ii The howitzer is elevated by the hand-wheel'l) in the usual manner, and the elevating-gear is clamped in position by turning the screw-clamp d. Then to bring the gun quickly to the loading piece in the form of a small lever (I? on the elevating-arm (Z is pressed inward, thereby bringing a nose (1" thereof against the springbolt U and by forcing the latter inwardly unlocking the howitzer, so that it can brought to the loading position by the haudie 13 independently of the elevatingnrin After loading the said howitzer can quickly be returned to iiring position, where it is antomatically locked again to the elevating-arm c (I by tho spring-bolt b" reengaging with the olcvating-arnn It will thus be seen that after the elevating-gear is once set for any desired angle of elevation it is unnecessary to again operate it unless the angle of elevation 9 is to be varied. We thus insure increased rapidity in iirin".

In some instances, as in the example illusor free end of the elevatingarin d a so trunnion extension is of oopushed in as the how- 05 is also provided '70 returning to i 1 the aforesaid position apushbe quickly trated by Fig. 6, we make the clamping-arc d in one piece with the elevating-arm d and fix the screw-clamp cl? to the side of their-ail.

What we claim, and desire to secure byLetters Patent of the United States, is-

1. In a field gun-carriage, the combination with the gun audits cradle, of an elevatingarm pivotally connected with one of the cradle-trunnions, gear for operating said arm, an aetuating handle fixed to said trunnions, and means for readily locking and unlocking said actuating-handle to and from said elevating-arm, substantially as and for the purpose specified.

2. In a field gun-oarriage, the combination with the gun and its cradle, of an elevatingarm pivotally connected With one of the eradle-trunnions, gear for actuating said arm, a bell-crank lever fixed to said trunnions and provided with a rearwardly-extending handle, and means for readily locking and unlocking said bell-crank lever to and from said elevating-arm substantially as and for the purpose specified.

3. In a field gun-carriage, the combination with the gun and its cradle, of an elevatingarm pivotally connected with one of the cradle-trunnions, gear for actuating said arm, means for locking" said arm'in its an gnlarly-adjusted position, a bell-crank lever fixed to the said trunnion and rovided with a rearWardly-extending handle, and means for readily locking and unlocking said bellerank lever to and from said substantially as and for the purpose specified.

4. In a field gun-carriage, the combination withthe gun and its cradle, of an elevatingtrm pivotally connected with one of the radle-trunnions, gear for actuating said arm, tclamp on said arm, a fixed slotted segment n which said clamp Works and to which said Mn is adapted to be fixed by the clamp, a iell-crank lever fixed to the aforesaid trunllOD and provided with a rearwardlyextendng handle, andmeans for readily locking nd unldcking said hell-crank lever to and rom said'elevati ng-arm, substantially as and or the purpose specified.

5. In a field gun-carriage,

'ith the gun and its cradle,

the combination of an elevatingelevating-arm arm pivotally connected with one of the cradle-trunnions, gear for actuating said arm, means for locking said arm in its angularlyadjusted position, a bell-crank lever fixed .to the said trunnions and provided with a rearwardly-extending handle, a spring-bolt for looking said. bell-crank lever to said elevating-arm and means for liberating said springbolt when the bell-crank lever is to be operated independentlyof the elevating-arm substantially as and for the purpose specified.

6. In a field gun-carriage, the combination with the gun and its cradle, of an elevatingarm pivotally connected With one of the eradle-trunnions, gear for actuatingsaid arm, means for locking said arm in its angularlyadjusted position, a bell-crank lever fixed to the said trunnion and provided with a rear- Wardly-extending handle,a spring-bolt on the bell-crank lever for locking the latter to said elevating-arm, and a puslrpiece on the elevating-arm for disengaging the spring-bolt from the elevating-arm substantially as and for the purpose specified.

7. In a field gun-carriage, the combination with the gun and its cradle, of an elevatingarm pivotally connected with one of the eradle-trunnions, gear for actuating said arm, means for locking said arm in its angular-lyadjusted position, a bell-crank lever fixed to the said trunnion and provided with a rearwvardly-extending handle,a spring-bolt on the bell-crank lever for locking the latter to said elevating-arm, a push-piece on the elevatingarm for disengaging the spring-bolt, an incline on the elevating-arm for actuating said spring-bolt as the elevating-arm returns to its position of reengagement with the springbolt, and a stop on the elevating-arm to relieve the springbolt from lateral stress as the parts are returned to firing position substantially as and for the purpose specified.

In testimony whereof our hands,in presence of two subscribing witnesses, this 26th day of August, 1902.
