WHEELED GUN CARRIAGE WITH WIDE SCOPE OF FIRE.

Specification of Letters Patent.

Patented July 9, 1918.

Application filed June 17, 1914. Serial No. 845,578.

To all whom z'tmay concern:

Be it known that I, EMILE RIMAILHo, a citizen of the French Republic, and residing in Paris, France, 98 Rue de la Victoire, consulting engineer, have invented certain new and useful improvements in and relating to Wheeled Gun-Carriages with Wide Scope of Fire, of which thefollowing is a complete specification.

In those gun carriages which at the moment of firing are in contact with the ground at four points, the latter points are represented on the one hand by the lower part of each of the wheels, (hereinafter called the axle wheel system) and on the other hand by the ends of two trails (hereinafter called the trail'system), special arrangement having to be made in order to enable all the four points of support to grip the ground during the firing.

The object of the present invention is the construction of a gun carriage in which the above purposes are secured, by connecting the axle-wheel system to the trail system through the agency of a spherical or ball joint, the male part of which is carried by one of the two systems and the female part by the other; the carriage proper, carrying the pivot which supports the gun can form part either of the axle-wheel system or of the trail system. I

On the drawings annexed:

Figure 1 is a plan with a part section of a first working construction,

Fig. 2 is an elevation with part section,

Fig. 3 is a section through AB of Fig. 2,

Fig. 4 is a section through C-D of Fig. 2,

Figs. 5 to 7 are similar views of another working construction,

Figs. 8 and 9 are respectively a plan with section and cross section of a variant,

Figs. 10 and 11 are details,

Figs. 12 to 18 show another working construction, in which Fig. 12 is an axial longitudinal section on the line GG of Fig. 16.

Fig. 13 is a vertical section on the hne H-Hof Fig. 12. a

Fig. 14 is a vertical section on the line II of Fig. 12.

Fig. 15 is a vertical section on the line JJ of Fig. 12.

Fig. 16 is a plan with part section on the line E-E of Fig. 12. V

Fig. 17 is a horizontal section on the line F-F of Fig. 12.

Fig. 18 is a view similar to Fig. 16 showmg the trails and the small carriage in another position relatively to the axle.

' Fig. 1 shows by way of example, a workmg construction in which the male part- 1 of the ball joint, is carried by the trail system, the female part 2 being carried by the axle-wheel; Fig. 2 shows in this case the body 3 of a gun carriage fixed to the system axle-wheel by means of the axle 4 and carrying the recess 5 for receiving the pivot supporting the gun.

Fig. 5 shows by way of example a form of construction in which the male part 1 of the ball joint is carried by the axle-wheel system, and the female part 2 is carried by the trail system. Figs. 6 and 7 in this case show a gun carriage body 3 fixed in the trail system and carrying the recess 5 for the gun pivot.

Figs. 1 to 7 likewise show the connections which allow all the relative movements which the two systems are required to .be able to carry out, in relation to each other. The ball joint allows the trail system (Fig. .1) to pass from

position

6, 7 to position 6., 7 the line 8 of the point of. sup port of the butt endsv being parallel to the axle when the axis of the trail system is perpendicular to the axis, but being able to take up the position 8 and 8 oblique relatively to the axle, according to therequirements of the ground.

Fig. 4 shows that the ball joint also allows the

trail system

6, 7 to be inclined relatively to the axle from. right to left or from left to right as required by the ground while the axle remains horizontal.

Finally if we consider the movement of elevation which the trail system must be capable of undergoingaround the axle, journal when the butt ends are raised, for instance, it may be desirable to include the whole of the carriage in this movement; with this object, for the working constructions of Figs. 1 to 4, a sliding piece 9 is able to undergo lateral displacement in the wide window 10 contained between the supowing to theballjoint', to assume right'and left of that perpe i dicular to the axle, the movement allowing the system to"'incl1ne "to and 7, the possibilities of inclining the system on eithefside of theperpendiculartothe axle and making it lean-right or le'ft,1are

Figs. 8;"and-9represent-a variant which; showsfithat it: isnpossible to confine oneselfto apart 'ball 21, the center of Which maybeplaced eitherfabove orbel'ow the axle or'elseon the axleitself. 1 "Evidently the' ball andthe socket joint can be replaced by a Cardan joint,and"the efiects' described above thus obtained.

It.will beremarkedthat, in 4' 1131911v l(1Figs, 12;;to 1 "Z) thepivot 4;9'of the "small carriage is mounted; on the ,tr'ail 'pfarallelto the axle,

The spherical part of the axle carries on *its upper race a-ylindri'cal vertical pin 51, the axis of which passes through the center "arms-tan and which serves as a pivot' for plate 5.2 belonging to the socket 18 of gudgeon 47. This plate carries a toothed segment 53 on'which thepinion 54; for direction pointing rnns. That is, when carriage is operated by pinion 54; it is merely for the purpose of training, andthe pinion 54L may control any displacement of carriage 5O independently' ofthe trail 1;; pinion 5% be ingjcontrolledby a wormwheel as indicated :in Fig; 12.1 ;The plateis-held in a. suitable position relatively to theaxl'eby means optv a triple clamping arrangement 55%56 57.

recess 43 provided in the center of the axle enables the wheel brake control to be lodged here so as to reduce the space occupied by the carriage a whole, and preventing the dust making its way into this brake.

This control comprises a box 63 (Figs. 12 and 17) mounted in an invariable position in a tube end 64 of the recess 43. This box carries at its outside end a hand wheel 65 fixedly connected with a screw 66 mounted so as to be able to turn without longitudinal displacement. This screw is in engagement with a nut 67 sliding in the box 63 and supporting a plate 68 on which is pivoted a pulley 69. A cable 7 O, the middle of which catches on this pulley, passes elsewhere onto two fixed guide pulleys 71 mounted in the recess 43, and its ends pass through the interior of the axle 44 and run out to the usual wheelbrake control levers, not shown, consisting of spring segments.

What I claim is 1. A wheeled gun carriage comprising an axle wheel frame, a trail frame united thereto by a ball and socket coupling, braking means carried by the wheels of the carriage, and means carried by the ball and socket coupling for controlling the braking means.

2. A wheeled gun carriage comprising an axle wheel frame, and a trail frame coupled thereto by a ball and socket joint, the ball disposed in the front of the trail frame and the socket disposed in the axle, said trail frame also provided with a pivotally mounted oscillatory small gun carriage.

3. A wheeled gun carriage comprising an axle wheel frame and a trail frame coupled thereto by a ball and socket joint, said joint consisting of a ball and neck thereon Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

Washington, D. C.

held in a recess formed therein, a pair of threaded half collars, the neck resting on the axle and extending through a two part socket, the internal section of which is cylindrical and the external section being po lygonal whereby a constant surface of support is obtained irrespective of the direction of the trails relatingly to the axle.

4. In a wheeled gun carriage comprising an axle wheel frame and a trail frame coupled thereto by a ball and socket connecting a cylindrical socket havin oppositely disposed gudgeons, said socket secured to a plate pivotally mounted on a vertical pin reaching from the upper portion of the axle, the axis of said pin passing through the center of the trail joint ball, said plate held to the axle by clamps concentric to the vertical pin, a tooth segment supported by said plate, direction pointing pinion meshing with said segment, said plate having a cylindrical surface in its lower rear portion concentric with the gudgeons.

5. A wheeled gun carriage comprising in combination an axle wheel frame and a trail frame coupled thereto by a ball and socket connection, a movable pulley and fixed pulleys therein, a brake operating cable threaded around said pulleys within the ball member of the socket, openings in the sides of the ball and the socket through which the ends of the cable may pass.

In testimony whereof I have hereunto set my hand at Paris (France), this fifth day of J une, 1914.
