In Germany December 31, 1932 17 Claims. (01. '102 40) form supports cheeks or bearing standards in r and partly in section showing the manner in which the weapon or a cradle for the latter is supported by means of its trunnions. The distinguishing feature of the gun support according to the invention is that the said support, for the purpose of facilitating the transportation in various manners, for instance especially on horseback, is easy to separate into the main parts here mentioned: the legs, the bottom frame, the top frame or platform and the cheeks or bearing standards. Each of the legs is fitted, at the foot end with a vertically adjustable foot disposed in a casing, which casing can readily be separated from the leg itself and, after the latter has been detached from the bottom frame, can readily be attached to'the latter in theplace of the leg, whereby the advantage is attained that the gun support (without legs) can be brought into position for firing from a platform that is not much larger than the bottom frame itself (for instance on a motor vehicle), There are further provided as accessories to the gun support two wheels, each journaled on an axle pin attached in a suitably sloping position on a head, which in a similar easy manner can be attached to the bottom frame in the place of a leg, the advantage being thereby attained that by replacing two of the legs of the gun support by the said wheels the gun support can be converted into a wheeled gun carriage with a stock (the third leg).

Figure 14 is an enlarged detail, partly in elevation and partly in section and showing the manner of attaching the wheels to the bottom frame.

A are the three legs of the gun support, B the circular bottom frame, C the top frame adapted to be rotated therein and D the cheeks, or bearing standards, at the top of which is a cradle-E for the gun F. G is the hand-wheel for the latoral-adjustment mechanism and H the handwheel for the vertical-adjustment mechanism of the gun, the first mentioned wheel having its shaft journaled in the top frame or platform and driving by a suitable transmission a pinion, which is in engagement with a toothedrirn g on the inner side of the bottom frame. The wheel H is connected through a suitable transmission (not shown) in a housing H to a shaft consisting of sections it two of which are universally jointed ath and between two of which sections is acontrolling clutch h. The terminal section n is connected to gearing h for vertical training of the gun. 7

At three points'on the outside of the bottom frame, spaced 120 from one another, there are fitted vertical U-shaped shoes 20 which are open on the front sides, and are welded to the said bottom frame. Each shoe carries at the top a horizontal bolt 21, obliquely disposed relatively to the frame. 'Each shoe carries somewhat further down on the inside of each flange, a short but heavy pin 22, the said shoe being filled out at the bottom by means of a solid block, the looking block 23, which is attached to the shoe by welding. I

' Each of these three shoes 20 serves to hold the inner end of one leg A and to attach the same to the bottom frame-B, the said leg which suitably is of I-shaped cross-section being fitted at the'inner end with a clip24 welded or otherwise secured in position. At the top of the clip 24 is a fork 25, which is adapted to engage the bolt 21 from below, forming together with the latter an open hinge 21, 25, while the said clip is fitted at the bottom with a toe 26, which extends in- 'wardly toward the bottom frame and, after. the

fork has been caused to engage the bolt 21, fits closely on top of the-locking block 23. The top side of the locking block 23 is fitted with a deep transverse groove, and the bottom side of the toe' 26 is fitted with a shallow groove confronting the first groove, the said two grooves forniing' to-S a manner that the said bolt by being all tom frame relatively to one another.

Ling boltmay be non rotatively mounted in a yoke the Way down into the recess will give free pas-- sage for the toe 26 closely above the locking block, while the said'bolt, when the same, after the leg has been brought into positon, is turned through a suitable angle, will be projecting up into the cylindrical, groove in the bottom face of the toe and, thereby will lock the latter and the loeking block'23 and, thereby, .theleg and the bot- The lockmember 28, which from a hanging position corre spending to free passage for the too can be swung,

up into a horizontal position, whereby the locking bolt will brought into its locking position.

' The said yoke member is arranged to be fixed in the last mentioned position by means ofv a threaded spindle 30 fitted with a hand wheel 29, for which spindle the central part of the said yoke member forms the nut, and screwed with its pin-shaped pointinto a corresponding hole 31 in the rear side of the locking block, where it is held in position by means of a clamping ring 32 adapted'to slide-transversely in the central part A threaded pin 33 pro-' of the said yoke member.- jects from the ring out through the side of the said central part of the yoke and is fitted with a nut 34', which by being screwed up against the central piece effects a lateral motion of the clamping ring 32 so'asto press the latter against the sp'indle 30.

It will be seen that after the lock 23, 2'7, 26 has been opened, the leg can be detached from the bottom member.

Instead of the hinge bolt 21 and the fork 25 being disposed at the top and the fork opening upwardly, the parts mentioned here may be situated at the bottom, and the fork be pen at the bottom, the locking device being then situated at the top. Such aconstruction offers theadvantage :that the locking parts do not have tdbeactuated so forcibly, as care can then be taken that the end of the leg shall then, at the top, rest against the front edges of the side flanges of the shoe 29, in such a. manner that the pressure from the top edge of the leg against the bottom frame willbe resisted there, while the pull acting on the bottom frame, at the bottom side of the leg will be transmitted through the hinge, which will be able to transmit these forces better than the lock.

Instead of a hinge bolt 21 running through and a broad fork 25 being used a short hinge pin- 22 may be used in each of the flanges of'the shoe 20 of the bottom frame as shown by I the, connection, later described, between thefoot end of the legand the casing for the adjustable foot of the same as shown in Fig. 9. I

For taking up the outward bending moment originating from the legs and acting on the part of the shoes 20 that projectsbelow the bottom frame itself, the said shoes are preferably interconnected by means of stays 35 I The top frame or platform C, which is rotatable in and on the bottom frame B,'but issecured against detachment from the bottom frame, as

long as the gun support is in use, is fitted with supporting rollers 36 and guide rollers 37, which latter, besides centering the top frame in the bottomfrain'e, also serve to hold the two frames together and, for that purpose are fitted with a flange engaging thebottom side'of a peripheral circular part of the bottom frame.

In order to' enable the t'op frame andthei bottom frame to be separated from one another when desired the flange rollers37 are each journaled on a pin 38 disposed eccentricallyi on the bottom end of a cylinder 39, which is'pivotedin the top frame or platform 13 and by means of a locking device is releasably locked to the top frame in the position in which. the rollers are in engagement with the bottom frame and, suitably, also in another, preferably diametrically opposite position, in such a manner that, after the cylinders 39 have been released and readjust eoLto disengage the" rollers '37 from the bottom frame, the top frame can be lifted from the bottom frame. In the construction sliown'the said locking device consists of a locking arm 41 pivoted at the top end. of the cylinder 3'9 to swingabout a horizontal shaft 40; One end of this arm is engagedby a pin 43 journaled in the cylinder and actuated by 'aspring 42, the result being that the other end thereof will beheld down mono or the other one of two preferably diametrically opposed notches 44 (see Fig. 6) in a ring 45 connected rigidly to the top frame, but can be lifted out from the same and then together with the cylinder be turned to' engagement with the other notch.-

Iii the construction shown for the gun support, the supporting frame D, which preferably con-- sists of two mainly vertical cheek walls 47 connected at the front by a. base plate 46, is connected to the top frame by being held at the front between two lugs 48 on the top side of the top frame and by engaging by means or a flange 49 beneath a flange 50 on the periphery of the top frame (see Fig.- 8). The frame is further locked at its rear to the top frame by means of bolts 52 adapted to slide in barrels or cylinders 51 fixed on the said top frame. Each bolt 52 engages a suitably conical hole 53 at the rear end of each of the cheeks. When the bolt 52 is pulled out from the hole 53, the supporting frame can be pushed forward in such a; manner that the flange 49 is freed from the flange 50, after which the sup orting frame can freely be removed from the top frame, since by the said displacement of the cheeksals'o the two parts of the elevation-adjuster shaft 7L have been disconnected from one another by separation of the parts of the clutch coupling m. The bolt 52 is preferably cylindrical and is journaled in the cylindrical barrel 51. Each bolt is fitted with a handle lever 54, working in a bayonet slot 55 iii the outer end of the barrel, as common in bolts, thus allowing the bolt to be locked in the opening 53 but permitting the bolt to be withdrawn from said opening.

The checks may at the front be connected to the top frame by means of a dove-tail connection instead of by means of a clutch and lateral guides, and the locking device at the rear may be of any other known suitable construction than the one here described, and the locking device, instead of being disposed at the rear, may be disposed at the front, the dove-tail connection or the clutch connection having then correspondingly to be disposed at the rear.

A foot 59 is provided at the outer end of each of the legs A, which foot is adjustable with respect to a foot casing 60 in vertical direction by means of an adjusting screw 58 provided with a handwheel 57. The foot casing 66, is detachably connected to the leg A itself, in similar manner the connection of the top end of the leg to the bottom frame, and by means of connecting and locking members also can be attached directly to the bottom frame in the place-of the leg, although it should be noted that if the cross-sectional depth of the leg is smaller at the foot end than at the top end, then the side flanges of the shoes of the bottom frame must be fitted with special hinge pins-the above mentioned pins 22belo'-.v the hinge bolt 21 for the fork of the leg.

The detailed arrangement of the connection between the foot casing 6i) and the leg A itself in the construction shown is as follows (see Figs. 9 and 10).

To the outer end of the leg A a frame 61 is welded or otherwise attached, the side walls of which carry each a short lateral pin 122 serving as hinge pins. The side walls of the casing 60 are extended as at 66' to form a fork embracing the frame 61 and having notched arms 125 engaging the pins 122. At the bottom of the frame 61 a locking block 123 is fixed, and in the top member of the frame there is rotatably held a hollow threaded spindle 63 having a hand-wheel 62. This spindle forms the nut for a threaded pin 64 supporting at its bottom end a cone 65 having at its lower end a cylinder 66, which seats in the locking block 123. Similarly to the top clip 2% of the leg the foot casing is fitted with a projecting toe 126 which when the hinge 122, 125 has been assembled engages on top of the locking block 122. The toe 12s on its bottom side a shallow cylindrical groove corresponding to the recess in the bottom side of the toe 26 on the inner end of the leg. The toe 126 is bifurcated and provided with a conical eye to receive the cone 65 on the threaded pin 64. Thus when by rotation of the hand-wheel 62 the cone 65 and the cylinder 66 have been lowered so far down into the locking block 123 that the top of the cone lies below the bottom side of the toe 126, the latter will be able to be moved along the top of the locking block, the two branches of the bifurcated toe passing each on one side of the threaded bolt 64, and whenthe toe 126 has thus been brought into position, the cone 65 can again be lifted and will then ascend into, and fill out, the conical eye hole formed in the toe to receive the cone, so that thereby the foot casing will be locked to the leg.

Fig. 11 shows the foot 59 with its foot casing 60 attached to the bottom frame B in the shoe 20 on the same. pins 22, and the toe 126 is locked to the looking block 23 by means of the locking bolt 27.

As accessories to the gun support (see Figs. 12, 13 and 1 1) two wheels 67 are provided, each disposed on an axle pin 68, which in a suitably angular position is attached in a head 69 of the The forks 125 enga e here the a craft guns and the like comprising a circular botsame height as the top end of the legs. This head forms at thetop a fork 225 corresponding to the fork 25 on the top clip 24 of the legs, and is fitted at the bottom with a heavy bottom plate 226, corresponding to the toe 26 on the said clip and with a cylindrical shallow recess in the bottom face exactly like the said toe, so that each of the wheels with the axle head belonging thereto can immediately be attached and locked to the bottom frame in place of one of the legs, the gun support being thereby converted into a wheeled gun carriage with a stock or trail formed by the third leg.
