Y'rRAv'n'Linie Loon FOR een cARRrAGns.

For gun'ca'rriagcs having,- a large range. and' provided with a quadrilateral' support on the ground composed of two-wheels and two spades, one of the means employed in ordei` that 'the' said' quadrilateral support may be adapted to the ground consists in pivoting'ithe' vehicle axle to the carriage by means a longitudinal spindle.` Suitable locking lmeans must be provided for lthevpivot in conditionsof travel. Y

When the sai carriage is provided'with an elastic suspension device for road travel, consisting 'for example of plate Ispring-sor like elastic means interposed between Athe can' riage'and'the,axle, it is necessaryjto vprovide locking means' in order vthat the `suspension parts shall not be subjected to the Itiring shocks'. E

Thepresentinventionhas for itsobject to provide'fan ai'rangementA whereby Ethe locking may be obtainedfineither ofl the abovementioned cases by theo'pcration of a single common control device in either direction, exclusive of all other operations, and chiefly without being obliged to raise the said carriage in order to provide for the expansion ol' the elastic parts of the suspension.

The said arrangement comprises locking elements and a control for actuating the said. elements. When the control is operated in a given direction, it brings the locking` elements into the firing position; the lateral inclination is le't free while the vertical motion is prevented by the said locking means. By operating the control in the contrary direction, the locking devices are brought into the position for road travel; the lateral inclination is now prevented, while the vertical motion is released.

rlhe appended drawings show by way of example which is no wise limitative, two emhodin'ients of the said invention.

Fig. l is a front elevational view of the first form ot construction, the carriage being,r reduced to its cross-piece.

Figs. Z and 3 are cross-sections on the lines iii- A and B-B of Fig). l respectively.

Fig. 4 is an elevational view of the same device with the springremoved, and Fig.. 5 is a vertical section on the line C-C of Fig.

Figs. G and 7 are views analogous to Fig'. 4, showing` the elements in their diliierent positions.

Figs. 8 and 9 are views analogous to Figs.

' Application led March 2'1, 1924, Serial No.r 700,920, and in France April 24, 19.23.

l and 7, relate to the second form of the device, with the spring removed.

Fig. l0 is a section on' the line D.-D o 'l Fig. y

ln the first form or" constructiointhe locking device consists of two wedges l which are slidablc on the axle 2 by means of a control screw 8 having` two threads in con trarydirections, each thread being engaged with corresponding threads formed in the said plates; the said screw is rotated for instance by a lratchet lever or a-handlc il. At the middle part of the axle 2 are two extensions 5 serving` supports and guides 'for the said wedges.

The wedges may be moved apart or may be brought together until. they are in Contact; when in contact, their upper surfaces coineide so as to form a cylindrical surface oi. revolution 6 whose centre line is the loi @"tudinal pivoting axis. The crosspiece 7 the carriage has a corresponding' cylindrical sur tace 8 whereby the carriage is caused to bear upon the aXle for the firing operation, and one ol' these elements can be laterally inclined with reference to the other. Upon the said cross-piece is revcluble an axle 9 which constitutes the longitudinal pivotand to which are secured at the middle part two transverse plate springs l0 and ll v-.fhose ends are attached to the vehicle asile by shackles; on the axle 9 is also revoluble retaining strap @Xtending,` below trie said 'wedges when in the tiring' position and preventing the cross-piece 7 dtrom being raised from the vehicle axle. The. said cross-piece is provided with two pairs et downwardly eftcnding lugs 13 having thereon the roller.V le with which the said wedges may co-operate when moved apart.

In this posi-tion oli the wedges, the sin face 8 of the cross-piece is allowed to descend, passingbetween the said plates which prevent any moven'ient of inclination et the carriage relative to the axle.

The control rod for the said wedges i.: through the centre oil the vehicle axle and is connected to the saine in an elastic manner by means of the springs l5, whereby all iai ring motion between the rollers and wedges is obviated when in the position of travelf In the second form of construction, Fien.

and l1, which are attached to the aide by shackles, are fitted at the middle part inte 8, 9 and 10, the plate suspension snrings l0 ses the members 'l (3 which comprise aniextension 17 andare traversed `by a. longitudinal axle 9. To the latter are pivoted on the one hand the crossfpjece'4 of the carriage and on the other hand tivo pairsI of'loent arrn's 18 Whose ends 19 can "lieinaintainedeither in the adjacent or separated positionffor. instance by means of a rod with double screw-thread 90 which isiturned V1oy1a handle or a ratchet lever 4 and the rod and link gear 21 which is properly jointed and sliclahle.

Vhen in the separated position, the two pairs-ot arms are held in tivo out-out portions 22 of the vehicle axle, thereby locking theisuspension by connecting the vehicle axle with thepivotinzg` axle 9. In this event the carriage can loe inclinedy laterally With reteneneertothe vehicle. axle by pivoting on the axle 9.

Wlieni moved together, the two pairs of' armsy comeinto` contact with the extensions 17 ot' the members 1G whilst their ends QB hold-the oross-piece 7, so that theisaid arms and thecross-piece heee-ine secured to the members 16 into which the vehicle springs arewlitted; i

The' carriage is thus suspended from the axle in an elastic inanneri and can nolonger pivot upon the axle 9.

lClaims:

1. In afield gunvvith Wide range, the coinbination of a carriage, an axle, an elastic slaaiension lwiwren the said aigle and the said' carriage, a longitudinall pivot about which the said carriage can turn relatively to the said axle, and a connnon. mechanism `for locking the `said elastiojsuspension and 'for locking thi,` carriage'upon its' pivot, said mechanism being` adapted to allow of locking,r Athe elastie suspension at same time as the unlocking of the carriage-.upon the longitudinal pivot, or the unlocking of the suspension a; same time as the locking of.` the' carriage upon this pivot.

2. In a field .f 'annon having a great tiring range, the, combination of an axle,.trans.erse plate springs pivoted at' the ends to the said axle, a longitudinal sha'lft mounted at the middle of the said springs, a gun carriage pivoted upon the said. shaft, movable elements which act in their irst position to permit the rotation oit the carriage on the said longitudinal shalt Whilc'preventing all vertical motion thereof relatively tothe said axle, and in the second position tofprevent all rotation oit the gun carriage onI the said shaft While pern'iitting the ascent ol thc carriage relatively to the said: aXle,vand` a -control `rod with right andV left hand screwthread which is screwed upon the said ele-A inentsand serves to change their position.

In testimony that I claiin thev foregoingv as iny invention, I have signed my name.
