Application filed October 1, 1923. Serial Io. 665,869.

(FILED UNDER THE ACT OF MARCH 3, 1 888, 22 STAT. L, 625.)

To allwkom it may conoem:

Be it known that I, BRYAN citizen of the United States, and a resident of- Davenport, county. of Scott and State 5 of Iowa have invented an Improvement in separable Gun Carriages, of which thefollowing is aspecification. w

The invention described herein may be used by the Government,.or'any of its ofiicers or employees in prosecution of work for the Government, or by any other person in the United States, without payment to me of any r0 alty thereon, in accordance with the act of arch 3, 1883.

The present invention relates to separable gun carriages and particularly to that type of carriage adapted to accompany infantry troops on the advance. The primary object of my invention is D the provision of a, gun carriage which may be knocked down for convenience in transportation.

Another object of this invention is the provision of a gun carriage in which the 5 traversing mechanism is embodied in the means for connecting the gun carriage pro er to the support therefor.

ith the foregoing and other objects in view, my invention resides in the novel arv rangement and combination of parts and in the details of construction hereinafter de- I scribed and claimed, it being understood that changes in the precise embodiment o the inventlon'herein disclosed may be made i within the sec e of What claimed without departing rom the spirit of the invention. i A practical'embodiment of the invention is illustrated in the accompanying drawings wherein: j v

Fig. 1 is a plan'view of the gun carriage; Fig. 2 is a view in side elevation;

Fig. 3 is a partial sectional vlew showing the elevating and traversing mechanism;'

and

Fig. 4 is a detailsectional view ,of the elevatin mechanism.

lie erring tothe drawing by numerals of reference: I have shown a t5-agun carriage support- P. JOYCE, a.

ed in its firing osition by a spade 6 and carriage wheels connected'together by an axle 8. The spade is provided with alined apertures!) adapted to receive a pin to lock the spade upon the limber in travel.

In the preferred embodiment of my 1nvention the gun carriage is provided with trail members 10 and llwhich are attached at one end to the spade 6. These trail members are made of an le iron and are trunnioned by means of 13 of a housing 14. The housing 14 is adapted to receive the carriage axle which is screw threaded as at 15 for a'portion of its length. One of the sleeves of the axle I housing is threaded as at 16 to engage with the threads on the axle so as to traverse the axle housing and the trail members connected1 theretoon the 'axle on rotation of the ax e.

The wheels 7 are journaled on the axle inthe usual manner and are retained thereon by offsets 17 on the axle against which the inner sides of the Wheel hubs seat and by nuts 18 threaded on the axle and seating against the outersides of these hubs. At

one endthe axle is rovided with an extension 19 and squared on this extension is a hand wheel 20 for manipulating the axle to traverse the trails.

In the referred embodiment of my invention t e housing 14 intermediate the f trail members 10 and 11 is formed with a chamber 21 separated by a artition- 22 from the axle housing proper. is adapted to contain the elevating mechanism for the gun which in the preferred embodiment of my. invention comprises a series of telescoping members "23, he outer rackets 12 on sleeves his chamber 21 members 23 and 23 of which a e hollow and internally and externally screw-thread;

ed to engage with one another and. the inner member 23 of which is externally screw threaded and adapted to intermesh with the internal threads of the next succeeding member 23".

t While I have chosen to employ three such telescoping membersE23, 1t

The outer telescoping member 23* is screw-threaded into a sleeve 24 to which is fixed a gear 25 meshing with a gear 26 mounted in a housing 27 secured on the chamber 21. The gear 26 is keyed on a shaft 28 on which is squared a hand wheel 29 formanipulating the elevating mechanism. A cap 30 secured to one end of the chamber 21 prevents movement of the sleeve 24 in the chamber in one direction, the partition 22 preventing movement in the opposite direction.

The outermost of the telescoping members 23 is provided with an aperture 31 adapted to receive a key 32 attached by means of a chain 33 to the gun cradle 36. This key passes through the aperture 31 and registering apertures 34 formed in lugs 35 on the gun cradle 36.

The gun barrel 37 may be mounted on the cradle in any suitable manner. As shown a casing 38 is provided which is adapted to enclose the gun barrel. On either side of the cradle are attached angle iron members 40 which extend rearwardly of the cradle and are fastened by means of Y-elips 41 to a trunnion 42 mounted in brackets 43' on the trail members 10 and 11. The Y-clips are detachably secured to the trunnion by means of pins 44 passed through registering apertures in the clips and trunnion and secured by means of chains 45 to the rearwardly extending arms 40. With a cradle mounting such as described the cradle in elevation is adapted to move in an arc whose center is the trunnion '42.

The gun-barrel may be fastened to the cradle against removal in travel or preferably may be releasably fastened thereto in a manner such as described in my co-pending application Serial No. 665,867, filed October '1, 1923.

Any suitable recoil mechanism ma be employed for counteracting the recoil of the gun, when fired. As shown a cylinder 46 is secured to the casing 38. A piston 47 is reciprocally mounted in this cylinder and secured to the gun barrel by means of the locking member 48 hinged at one end between lugs 50 formed on the'gun barrel and secured in locking position between said lugs'by means of a spring pressed plunger 51 mounted in a lug on the gun barrel.- In

this manner the piston is secured'to thegun barrel so as to move therewith in recoil and in counter recoil.

The usual sighting mechanism 52 is provided and the sighting mechanism is carried on the trail member 11 which trail member extends somewhat beyond the axle 8 and is secured to said trail member'by a bracket 53 ivoted to the trail member.

' ovement of the gun-is transmitted to the sight by means of a bracket 54 fixedly secured to the trunnion 42 and connected by links 55 and 56 to the sight bracket.

The gun may be adjusted by manipulation of the hand wheel 20 and 29 for firing and may be knocked down for transport for carriage by mules or the troops serving the gun. In order to separate the parts of the as one load, the cradle and casing as another load, the trail members and spade as a third load and the axle, wheels and sight is a fourth load.
